How does a plaster saw work without touching the body?

Let's talk about the history of plaster saws. The plaster saw ("Plaster cast cutter") was first patented by Homer H Stryker in the 1940s, and the most common cast cutting saw used today still bears his name: Stryker. In his patent application, the plastic surgeon wrote: "My improved tool is very effective at cutting castings or other hard materials, but if the cutter accidentally touches human skin and does not cut fabrics or other objects, it will not cut or damage the skin surface or material unless they are quite strict support." Although it is difficult to imagine that gypsum removal technology has not improved much in about 70 years, sometimes simplicity is the purest form of genius. Plaster saws are powered by electricity and they plan to use it on your arms or legs to cut off the plaster that touches your skin. How can you protect yourself from bloody disasters? All in all: resistance Once you know this secret, you can be a little more relaxed when the rotating metal saw blade falls on your body. Resistance is not in vain. The principle that makes it work is very similar to what you notice in your daily life: If you try to write on a piece of paper that has no support, you can't write a lot. The paper will only bend and move, with almost no resistance. But once the page gets hard, your pen or pencil will generate enough friction to mark the paper. The same is true for using a plaster saw. Since the saw blade only vibrates and does not rotate, the skin can withstand contact without being cut (with a few exceptions). Therefore, the inflexible casting material - gypsum or fiberglass - provides a lot of resistance and the plaster saw can do its job.

What problems should attend to when using a bone drill?

Bone drills are electronic devices used to drill holes in bones to enable the insertion of nails, screws, etc. (also known as orthopedic twist drills) that are typically used during surgery. Electric bone drill bits are divided into bone drill bits, pendulum hammerheads and hollow drill bits. Precautions before using the bone drill: Metal allergy is disabled. Elderly, osteoporosis, diabetes and other patients who are not suitable for orthopedic surgery should be used with caution. 3, The electric bone drill cannot be dismantled, cannot be knocked at random, so as not to affect the performance; before drilling, confirm that the drill bit is firmly fixed. It is strictly forbidden to use the scope of surgical instruments; it is strictly forbidden to use the solvent that is corrosive to the equipment for wiping and immersion sterilization. When using the drill bit, the water in the battery case should be protected from damage, the battery may be damaged or the electrical equipment may be short-circuited. Maintenance method of electric bone drill: A method of preventing water in a battery case and shorting an electric appliance. First, prepare two sets of cloth for each bone drill and use a cloth cover to maintain sterility before use. In use, a sterile towel wrap is used to expose only the drill bit, and the treated towel is wetted and replaced in time. Second, the rechargeable bone drill is directly wrapped with a disposable surgical cream to expose the drill bit and then peeled off and pasted after use. The maintenance method of the charging bone drill is to take out the drill bit after use, connect the drill bit, wash the blood and dirt with dry saline gauze, and then place it on a spare cloth or directly into 40% formalin. Disinfect in a smoking box, disable high-pressure steam or soak disinfection. Factors that affect the effect of the bone drill. The application effect of the bone drill is closely related to the cutting force and the cutting temperature. Excessive cutting forces can cause breakage. Excessive temperatures can cause thermal damage to bones. As the cutting speed increases, the risk of bone thermal damage and cracks gradually decreases. As the feed rate increases, the risk of bone thermal damage and cracks gradually decreases. According to the clinical situation, the cutting speed and feed rate should be maximized, so that the application effect of the bone drill is better. Ruijin is an internationally renowned brand in the field of high-quality medical devices, producing high-quality medical bone drills, hollow saws, oscillating saws, reciprocating saws and medical electric plaster saws.

Bone drill use and precautions

Bone drills are ubiquitous in many surgical fields, including orthopedics, neurosurgery, craniomaxillofacial and ENT. Cylindrical channels are typically made in the bone using a bone drill to accommodate screws or other threaded devices for rigid fixation provided by the integration of bone (cancellous bone and/or cortex) with the threads. Bone drills are also used in the preparation of bone tunnels, such as anterior cruciate ligament reconstruction. The operating environment of the surgical bone drill bit is unique and very different from the engineering drill bits used in manufacturing or traditional non-bioengineering (building, construction, etc.). What should we pay attention to when using bone drills in this special environment? 1.The medical bone drill is a short-term product that is used for 10 minutes each time. Can not be used continuously for a long time. 2.The battery is strictly prohibited from high temperature and high-pressure sterilization. After the operation, the battery should be taken out of the medical bone drill and placed in the package. If it is not used for a long time, it should not be charged and discharged once to avoid the aging of the plate. 3.The charger power cord cannot be exposed to oil, chemical solution erosion and mechanical damage. 4.The equipment nurse should master the function of the device and the correct installation and use methods. Pay attention to maintenance. Only when properly maintained can the service life be extended and the expensive medical equipment can be used for a longer period of time.

The effect of using a bone saw

In the past, Gigli and manual saws were used. It has now been replaced by pneumatic and electric saws. Over the years, bone saw blades have been significantly improved in manufacturing and design to improve accuracy and reduce the side effects of bone cutting. Despite the progress, there are still many adverse effects. E.g: Saw blade heating Friction generates a lot of heat, and too much heat can damage the meat and cells around the saw blade. Interestingly, however, they found that brine irrigation during the cutting process had little effect on temperature. Vibration frequency Pneumatic and electric hand-held bone saws generate vibrations, and this cumulative effect can be harmful. Because the vibration of too high frequency will make the numbness of the arm lose its perception. We know that the amount of vibration and daily use time when using large industrial tools is significantly higher than the amount of vibration generated during sawing during surgery. However, we still need to further evaluate the long-term cumulative effect of using a vibration tool to obtain a definitive answer because it represents a potential hazard. Produce noise High levels of noise can impair hearing ability and affect speech recognition. However, some researchers have shown that although the sound level of the instrument ranges from 19.6 dB to 73.1 dB within 3 meters, the exposure frequency is small, so the staff has no effect on hearing and speech loss. Finally, there is no evidence that the noise generated during surgery is a direct cause of hearing loss or speech difficulties. In summary, the noise generated during surgery is a potential risk for further research. Cutting errors and debris Inaccurate cutting due to blade and cutting block groove design or operator error can have an adverse effect. Cutting errors will affect implant alignment, which can have serious long-term effects. Bone and metal fragments generated during the cutting process accelerate wear. Using appropriate blade thicknesses and properly matched retention slots will alleviate these problems. Therefore, the best bone saw blades can provide accurate bone cutting without generating too much heat, vibration and noise. Read the full article

New tools in surgery - bone drill

A long time ago, people began to use bone cutting in surgery. Bone drilling is now one of the most common cutting tools. The components of the bone drill: A bone drilling device is a device designed for orthopedic surgery. Because electric energy can make it speed extremely fast, bone drills are usually electric. The instrument has bone physical drilling power. The bone drill is made of surgical grade material and can be operated without adversely affecting open wounds. Surgeons using bone drills can save many patients who require bone treatment. A bone drill is used to mount the pin into the patient's bone and the surgeon may need to drill to secure the pin. This type of surgery is not strictly limited to the repair of a fracture. Bone marrow is also used when bone marrow is extracted from bone, and bone marrow is removed by drilling through small holes in the bone. In general, the cave can gradually fill the new bone according to the body's ability to regenerate, and the bone drill can easily perform this function. If you use the original hand tools, it can take hours and the chances of successful surgery are small. Now with electric bone drills, the surgery can be completed in a matter of minutes, providing patients with a great chance of survival. About electric bone drills and manual bone drills: The advantages of electric bone drills are twofold compared to manual bone drills. Manual bone drilling takes a long time and the surgery is not very precise. Electric bone drills create precise-sized holes in the bone in a fast and rigorous manner, greatly reducing drilling time. Wuhu Ruijin Medical Co., Ltd. specializes in the development, production, and sales of medical orthopedic drilling tools for more than ten years, including bone drills, hollow drills, high-torque hip drills, and craniotomy drills.

How to use a cast cutter safely?

A cast cutter is a device that removes cast material without damaging the skin. Please note the following when operating cast cutter: Equipment maintenance must be carried out by professional technicians. The continuity of the cast cutter floor should be checked regularly. The continuity of the cast cutter floor should be checked regularly. The power cord should always be away from the blade cutting area. When disconnecting, unplug the cast cutter. Never pull on the power cord. Also, to ensure safety, plug the device into an outlet labeled "Hospital Class." Do not operate the equipment in areas where flammable or explosive gases may be present. Disconnect the power cord before replacing the blade. Do not autoclave or immerse any liquids. Also, keep your hands away from the cutting area when operating the device. At the same time, excessive noise is generated during the cutting process, so you should take care to protect your ears. Practical tips for reducing the risk of cutting or burning skin when removing castings: A sharp saw blade should be used. Because the extra friction caused by the blunt blade generates a lot of heat. When the casting is removed, it is filled with a rigid strip of plastic to form a barrier between the saw blade and the patient's skin. If there is no such device, a wooden tongue depressor can also be used to protect the skin at both ends of the casting. It is recommended to turn off the equipment regularly until it is sufficiently cooled, especially when cutting hard materials such as fiberglass and castings. Do not risk burning patients. Where practicable, the bone protrusion should be cut, not cut, to minimize the risk of direct blade contact and thermal damage. Read the full article

Why use a craniotomy drill during surgery?

A craniotomy drill is a piece of surgical equipment that is surgically formed into a hole in a skull, also known as a drill bit. Depending on the type of surgery, the craniotomy drill can be used for further surgery or maybe the only injury to the skull. Simply put, this hole is a small hole that is operated by a craniotomy drill on the skull. Craniotomy drill can be used for a variety of reasons, such as performing a larger craniotomy to allow cerebrospinal fluid drainage or chronic blood drainage. Usually performed under general anesthesia and involves surgical removal of part of the skull. Craniotomy drill is an essential part of most brain surgery. Why? The skull is very hard and it is impossible to make a traditional incision with a scalpel. Saws can be used to cut bones, but cutting the skull requires special skills and techniques to prevent damage to the brain. Drilling allows controlled cutting in the skull without penetrating trauma to fragile brain tissue. The drill hole of the craniotomy can be considered as the beginning of the incision for brain surgery, not the surgery itself. The surgeon can place multiple drill holes and then use different tools to connect the holes and lift a portion of the skull, which provides the surgeon with a working window. Use a craniotomy drill when the brain has problems that must be treated surgically. In order to enter the brain tissue, the skull must be opened to allow access to the brain. In most operations, placing a drill hole in the skull is the best way to treat a disease or injury. Neurosurgeons use craniotomy drills during craniotomy to enable them to complete various brain diseases and injuries. Some of the most common ones include: Relieve pressure on the brain Place a monitor and read the pressure inside the skull Removing blood clots Removing tumor Treating seizures Remove foreign objects Place medical devices, such as shunts or chemotherapy wafers Ruijin specializes in the development, production, and sales of medical devices for more than ten years, including bone drills, hollow drills, oscillating saws, and craniotomy drills, etc. Ruijin is the medical device of choice for your trauma and plastic surgery.
