The Uses and features of Surgical Oscillating Saw.

Uses and features:

The surgical oscillating saw is one of the irreplaceable power tools for joint surgery. High temperature and high-pressure surgical swing saws have replaced industrial drills that can only be fumigated. A sharp surgical oscillating saw can be used for high temperature and autoclave sterilization. It can withstand temperatures up to 135 ° C and autoclave at 1.6 MPa. Some fumigation cannot kill bacteria and viruses, shorten the disinfection time, only 20 minutes at 135 ° C high temperature and high pressure, which has won valuable time for emergency surgery patients.

The surgical oscillating saw is mainly used for hospital surgery. This instrument is optional. The utility model has the advantages of beautiful appearance, small volume, light weight, no wires, convenient carrying, safe operation and short operation time.

Structure: The surgical oscillating saw consists of a main unit, a charger, and a battery. The outer casing of the product is completely enclosed. The charger is not intended for use as a medical electronic device.


The safe use of medical devices is directly related to the safety of patients and medical device users. Therefore, standards must be established to regulate the development, production, use, and maintenance of medical devices. Therefore, it is necessary to strengthen the maintenance and management of medical devices, improve the maintenance and maintenance of medical devices, extend the service life of medical devices, reduce costs, reduce waste, and improve medical quality.

Here are some maintenance methods for you:

  1. Prevent microscopic duration and timely eliminate the influence of external factors on equipment;
  2. Take preventive measures to prevent emergencies and ensure the safe operation of equipment;
  3. Establish a practical, regular inspection system to detect and eliminate hidden dangers of the device itself.

About how a cast saw works

  1. How a Cast Saw Works.

Cast saws have a sharp, small-toothed blade that rapidly vibrates back and forth; it does not spin around like a circular saw. Against the firm surface of the plaster or fiberglass, the cast saw will cut through the material. However, against your skin, the cast saw simply moves the skin back and forth with the vibration, not cutting into the skin.

Newer cast saws have become even easier for patients to tolerate. The most significant difference is the noise coming from the motor of the saw. Older cast saws tend to have very noisy motors that can be frightening, especially for children. Newer saws have much quieter motors that cause much less anxiety for patients.

  1. Are Cast Saws Safe?

Cast saws are very safe, but they should only be used by personnel who have been trained in their proper use and how to avoid problems. Improper use of a cast saw, or use of a cast saw that has worn blades, can cause problems. Cast saws are safe, but there are possible complications of their use that can occur.

  1. Making It Easier to Remove the Cast.

Many patients, especially younger children, are frightened of cast saws, but there are some things that can be done to make the experience less traumatic.

Explain to kids what is happening. Don’t let the doctor or cast tech rush in and start removing the cast without showing the patient the equipment and how it works. Fear of the unknown is usually much worse than the fear of the saw.

Show the patient that the saw will not cut the skin. Skin lacerations are the most common fear, and demonstrating that the saw will not cut your skin can help. I always press the blade of the running cast saw against my hand to demonstrate that it’s safe.

Bring headphones. A cast saw can be noisy, and often the noise is more upsetting than the actual feeling of the saw. Earmuffs, headphones, or a noise-canceling device can help. Often kids will enjoy listening to music while the cast is being removed.

The application of bone saw and bone saw surgery

A bone saw or saw a cutter is a group of tools used to penetrate or amputate bone. Since amputation did not become a surgeon’s job until the mid-19th century, so bone saws are one of the most commonly used tools for surgeons and the most important part of all their tools, although scalpels are now the most commonly used tool for surgeons.

Bone saws or bone saw blades and reciprocating blades are typically used to cut small and large bones in a way that enables the best surgical outcome for the patient.

There are several different bones saw surgery:

  1. Unpowered – Unpowered bone cutting implements include varieties of hacksaw and saber saw. In many applications, the saw is used in specialized jigs to provide accurate, measurable cuts, e.g. in knee surgery.
  2. Specialized saws such as the Gigli saw, a cable made of sharp strands of wire, are also used in some procedures.
  3. Reciprocating – Usually a powered rotary oscillation is applied to a specialized cutting implement to provide smooth controllable cuts into bone, for applications, from skull cutting to rib cutting, which is usually used where precision is necessary.
  4. A sternal saw is a reciprocating bone cutter, used for cutting through the sternum during chest surgery.

When people choose and adapt to computers and the Internet, they begin to have many diseases related to radiation, sedentary lack of exercise, vision loss is faster, and anxiety is more likely.

Today, I want to say why medical bone drills are called perfect ergonomics?

First, what is the medical bone drill structure?

The medical bone drill includes a main body and a drill chuck, and the main body is provided with an electronic device. The power take-off shaft of the electric device is connected to the drill chuck, and the surface of the main body is covered with a sterile outer casing. Such a design can protect the body from sterilization, thereby stabilizing the performance of the electronic components of the bone drill and extending the service life.

Second, what is the use of medical bone drill?

It is mainly used for clinical operations such as cutting, drilling, and grinding of bone tissue.

Third, what are the characteristics of the medical bone drill?

  1. Simple structure, convenient manufacturing, and low cost.
  2. The operation part is small in size, light in weight, easy to operate, stable, safe and fast.
  3. The motor power and control part is separated from the drill body to facilitate high pressure or disinfectant immersion disinfection.
  4. Operate the drill body without any power supply, safe and reliable.

Therefore, it is safe and reliable, and it is easy to operate successfully. It is called the perfect ergonomic design.

In addition to medical bone drills; we company also have other major products including multi-function hollow drills, swing saws, reciprocating saws and medical electric plaster saws, which can be used in many surgical operations such as trauma surgery, thoracic surgery, joint surgery, veterinary orthopedics.

Reusable surgical instrument cleaning questions.

Reusable surgical instruments provide a potential pathway for pathogen transmission in medical procedures. Therefore, the purification process using surgical instruments is an important step in preventing medical-related infections.

Global medical accidents due to improper decontamination of surgical instruments, inadequate or unsuccessful, indicate potential defects in the decontamination practices of medical devices.

According to statistics, in the medical literature database, Medline and Embase, articles detailing events related to the unsuccessful decontamination of surgical instruments were identified. Among them, 21 articles were identified to report incidents related to decontamination failure.

A large part of the incident involves attempting disinfection of the surgical instrument rather than disinfection. It has been reported that the instruments used in ophthalmic surgery are associated with decontamination failure.

Analyzing only the limits of published events means that you must consider the possibility of under-reporting (including an unwillingness to publish failures). Despite these limitations, the risk of cross-infection of reusable surgical instruments is relatively low, subject to cleaning/sterilization procedures. Reporting the diversity of events also indicates that failure is not systematic.

Despite the challenges of the decontamination process, iatrogenic infections directly related to the report appear to be rare. Healthcare professionals should be aware of the precautions associated with different SPT cleanups and should review the manufacturer’s instructions prior to purchase.

Ruijin Medical has been involved in the medical industry for more than 10 years, and the instructions of electric surgical tools are clearer. If you are still looking for quality electric surgical tools, Ruijin Medical is your best choice!
