[0016] A bone saw capable of collecting bone fragments according to the present invention will be described below in conjunction with the accompanying drawings.

[0017] In the first embodiment of the present application, Figure 1 As shown, a bone saw capable of collecting bone fragments (hereinafter referred to as "this patent") comprises a bone saw body 1, a tooth chain 2, a control block 3, a bone fragment collection component 4, a device host 5, a drain pipe 6, a control button 7 and a handle 8. The front end of the handle 8 is fixedly connected to the device host 5, a groove is formed on the surface of the end of the handle 8 close to the device host to install the control button 7, a through hole is formed at the lower rear part of the device host 5 to install the drain pipe 6, the bone saw body 1 and the bone fragment collection component 4 are respectively installed at the upper and lower parts in front of the device host 5, the tooth chain drive motor 1-1 drives the tooth chain 2 on the surface of the bone saw body 1 through a transmission shaft and a gear, a rectangular through hole is formed in the middle part of the bone saw body 1 to install the control block 3 which can move forward and backward, the lower part of the control block 3 is connected to the front section of the bone fragment collection component 4 through a bracket, the rear end of the bone fragment collection component 4 is connected to the processing hole 5-1 of the device host 5, the upper part of the retractable collection slot 4-1 of the bone fragment collection component 4 is aligned with the tooth chain 2, the rear end of the processing hole 5-1 is connected to the drain pipe 6, and the drain pipe 6 is connected to the negative pressure collection device through a pipeline.

[0018] The utility model number is CN209695303U, which is a fish-belly-shaped double-toothed osteotomy saw (hereinafter referred to as "the patent"). The application only allows the broken bones to be taken out of the osteotomy site, but does not solve the problem that the broken bones will be scattered on the blade or other surfaces. The patent adds a broken bone collection component 4 that can collect broken bones under the bone saw, and cooperates with a counterclockwise rotating tooth chain 2 to allow the broken bones to be directly brought into the broken bone collection component 4, thereby effectively preventing the broken bones from splashing.

[0019] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 2 As shown, in order to prevent the broken bones from being too large to be blown by the wind, the front collecting roller 4-2 is installed on the inner side of the front end of the retractable collecting trough 4-1 through a rotating shaft, the front end of the collecting roller connecting rod 4-3 is hinged to the rotating shaft of the front collecting roller 4-2 through a bearing, and the rear end of the collecting roller connecting rod 4-3 is connected to the rear collecting driving roller 4-4 through a bearing, and the brackets on both sides of the collecting roller connecting rod 4-3 are movably connected to the collecting roller connecting rod slide rail 4-5 on the inner side of the processing hole 5-1 through rollers and sliders, and the broken bone belt 4-6 is connected end to end and rolls counterclockwise on the front collecting roller 4-2 and the rear collecting driving roller 4-4, and the retractable collecting trough 4-1 is formed by splicing a plurality of U-shaped sections front and back, and the retractable collecting trough 4-1 is realized by slide rails and limit blocks between the plurality of U-shaped sections, and a stretchable silicone film is provided on the inner surface of the retractable collecting trough 4-1.

[0020] In order to further optimize the working efficiency of the present application and minimize the problem of bone fragments being thrown out from the upper part by the toothed chain 2, a protective cover is provided on the upper part of the bone saw body 1. In this way, although a small amount of bone fragments will still splash, the bone fragments will be concentrated and scattered in one place through the restriction of the protective cover, which is convenient for subsequent cleaning. In order to allow medical staff to better choose the power supply method, the rear part of the handle 8 is connected to a power supply line or a battery pack.

[0021] When in use, a bone saw that can collect broken bones is installed, connected to the corresponding power supply equipment and put into use.

[0022] When the utility model is in use, the specific operations are as follows:

[0023] When in use, the medical staff first loosens the screws of the control block 3 so that the control block 3 can move back and forth in the rectangular hole of the bone saw body 1, and then operates the retractable collecting slot 4-1 of the bone fragment collection assembly 4 through the control block 3 according to the size of the bone to be sawed, and the front collecting roller 4-2 inside it will drive the collecting roller connecting rod 4-3 and the rear collecting driving roller 4-4 to move forward along the collecting roller connecting rod slide rail 4-5. When the retractable collecting slot 4-1 is retracted to the appropriate position, the screws of the control block 3 are tightened again to fix the control block 3, and the doctor can hold the handle 8 and press the control button 7 to drive the tooth chain ... The motor 1-1 drives the tooth chain 2 to rotate rapidly along the bone saw body 1, and the tooth chain 2 on the lower side of the bone saw body 1 rotates toward the device main unit 5, so that the sawed bone fragments will splash toward the device main unit 5. Since the front end of the retractable collecting tank 4-1 is close to the bone, the splashed bone fragments will also directly enter the retractable collecting tank 4-1, and the rear collection driving roller 4-4 drives the bone fragment shifting belt 4-6 to continuously shift the bone fragments into the processing hole 5-1, so that the bone fragments can quickly enter the processing hole 5-1, and under the negative pressure given by the external negative pressure absorption device, the bone fragments enter the processing hole 5-1 and are discharged to the absorption device through the sewage pipe 6.

[0024] In summary, a bone saw capable of collecting bone fragments in an embodiment of the utility model adds a bone fragment collection component 4 capable of collecting bone fragments under the bone saw, so that the bone fragments will not splash onto the blade or the surface of other objects, thereby ensuring the smooth completion of the operation.
