Oscillating Saw Head Assembly for Orthopedic Detachable Saw Blade Assembly

Abstract

The invention discloses a swing saw handpiece assembly of a detachable saw blade component in the orthopedics department. The swing saw handpiece assembly comprises a main machine joint and the saw blade component installed on the main machine joint. The saw blade component comprises a saw blade, a transmission part and a sheath body used for installation of the saw blade and the transmission part, and at least a part of the sheath body and all moving parts are of detachable structures. The structure of a swing saw with the sheath body is adopted, little friction exists in use, and vibration, noise and heating are low; because the sheath body can be held by hand, the saw blade is easy to control, and smooth operation of a surgery is facilitated; the whole sheath body or a part of the sheath body or all the moving parts are of detachable structures, can be cleaned and disinfected after operation, and then continue to be used, and therefore repeatability is achieved, internal parts can be replaced after being damaged, and use cost of a patient is reduced; matching precision and strength of components of the whole saw blade can be guaranteed because of the detachable structures, and motion vibration is further eliminated to guarantee the operation effect.

Description

technical field [0001] The invention relates to a medical device, in particular to an accessory part used for an orthopedic operation swing saw device in a surgical operation. Background technique [0002] Oscillating saw (vector saw) is a commonly used tool in orthopedic surgery. It is completed by the orthopedic saw equipment (handle) driving the saw blade to swing. In the prior art, ordinary large swing saw is usually used to remove bone tissue. Due to the long length of the saw blade , large swing vibration, high noise, poor operability, and easy friction with the mold base, generating heat and wear debris, which is not conducive to normal operation. In order to solve the above problems, there is a swinging saw blade with a sheath, which is provided with a reciprocating drive mechanism in the sheath. The swing is driven by the principle of leverage; and in order to control the thickness of the saw blade to facilitate the operation and at the same time ensure the overall...

Problems solved by technology

[0002] Oscillating saw (vector saw) is a commonly used tool in orthopedic surgery. It is completed by the orthopedic saw equipment (handle) driving the saw blade to swing. In the prior art, ordinary large swing saw is usually used to remove bone tissue. Due to the long length of the saw blade , large swing vibration, high noise, poor operability, and easy to rub against the mold base, resulting in heat and wear debris, which is not conducive to the normal operation

In order to solve the above problems, there is a swinging saw blade with a sheath, which is provided with a reciprocating drive mechanism in the sheath. The swing is driven by the principle of leverage; and in order to control the thickness of the saw blade to facilitate the operation and at the same time ensure the overall strength of the saw blade, two sheath blades are formed by stamping thin-walled sheet metal and fixedly connected as a whole, which has strong integrity and strength It can meet the needs; however, the structure cannot be disassembled, and because of the thickness, it forms small gaps, which cannot be cleaned after use. In order to ensure the therapeutic effect and avoid cross-infection, it can only be used once

Due to the above reasons, a lot of use costs are wasted and the patient’s burden is increased; and because the thin-walled sheet metal is used for stamping and combined forming, the matching accuracy and strength of the entire saw blade parts cannot be guaranteed, which affects the surgical effect
