Description

Technical Field

[0001] This application relates to the field of protective device technology, specifically a protective device for preventing splashing during filing and sawing. Background Technology

[0002] During bone sawing and reaming of the acetabular fossa, the oscillating and rotating forces of the saw and reamer generate splatter of bone fragments, blood, and tissue. To prevent occupational exposure to these splatters, protective devices can be used to shield the area. Traditional protection involves using gauze or a surgical drape to block the splattered bone fragments, blood, or tissue in front of the surgical field. However, this method not only provides insufficient protection but also hinders the surgeon's real-time observation of the surgical area and affects intraoperative procedures. Utility Model Content

[0003] The purpose of this application is to provide a splash protection device during bone filing and sawing operations to solve the problems mentioned in the background art, such as insufficient protection range, obstruction of surgeons' observation of the real-time surgical area status, and impact on intraoperative operations.

[0004] To achieve the above objectives, this application provides the following technical solution: a protective device for preventing splashing during filing and sawing, comprising: a protective device body, a tightening strap, and a fixing component. The protective device body is composed of a first transparent plastic film and several sets of second transparent plastic films. The first and second transparent plastic films are shaped like trumpets. The proximal end of the second transparent plastic film is fitted onto the outside of the device, and the distal end of the second transparent plastic film is bent inward. The first transparent plastic film is pressed and adhered to each other near the bend of the second transparent plastic film. The parts where the first and second transparent plastic films are adhered are bonded with a multi-point back-side adhesive material. The distal end of the first transparent plastic film is bent outward. The tightening strap is located outside the proximal end of the second transparent plastic film at one end of the device. Small teeth are formed on one side of the outer wall of the tightening strap. The tightening strap is made of soft plastic. The fixing component is located on the outer wall of the tightening strap.

[0005] By adopting the above technical solution, not only can the splattered bone fragments, blood, and tissue be shielded, but when the splattered material adheres to the inner surface of the No. 1 transparent plastic film and affects the surgical field of vision, a brand new, unused No. 2 transparent plastic film can be unfolded by pulling it out and replaced with a new No. 1 transparent plastic film, so as not to affect the surgeon's view of the specific condition of the surgical area.

[0006] Preferably, the fixing component includes a first block integrally formed on one side of the outer wall of the tightening band, a first groove formed inside the first block, and a second groove that passes through and connects the two sides of the first groove.

[0007] By adopting the above technical solution, the internal fixed rod can be made to rotate stably.

[0008] Preferably, the fixing assembly further includes a fixing rod rotatably connected to one of the two sets of slots via a shaft and a handle integrally formed on the outer wall of the fixing rod.

[0009] By adopting the above technical solution, the handle can be held by a person, thereby driving the connected fixed rod to rotate through the shaft.

[0010] Preferably, the fixing component further includes a second block integrally formed on the other side of the outer wall of the tightening band and a third groove formed in the second block.

[0011] By adopting the above technical solution, the mounting block in slot 3 can be rotated stably via the shaft.

[0012] Preferably, the fixing assembly further includes a mounting block rotatably connected to the inside of the third slot via a shaft, a guide rod slidably connected to the inside of the mounting block, a large toothed block integrally connected to one end of the guide rod, and a spring sleeved on the guide rod, wherein the large toothed block meshes with the small toothed block of the tightening belt.

[0013] By adopting the above technical solution, the large toothed block can be engaged with the small toothed block of the tightening belt through the compression of the spring.

[0014] Preferably, the fixing component further includes a fourth groove formed on the mounting block and elastic blocks bonded to both sides of the inner wall of the fourth groove.

[0015] By adopting the above technical solution, the elastic block can be used to position the fixed rod.

[0016] In summary, this application includes at least one of the following beneficial effects:

[0017] 1. By setting up two transparent plastic films, a first-layer transparent plastic film and a second-layer transparent plastic film, the second-layer transparent plastic film is adhered to the first-layer transparent plastic film at multiple points using adhesive material on its back side. During the process of bone fragments, blood, and tissue splatter, these substances will initially adhere to the surface of the first-layer transparent plastic film. When the surgeon cannot see the surgical area through the first-layer transparent plastic film, pulling on the first-layer transparent plastic film will unfold the bent end of the second-layer transparent plastic film, causing the adhesive material on its back side to detach, thus separating the first-layer transparent plastic film from the second-layer transparent plastic film. At this point, the first-layer transparent plastic film, contaminated with bone fragments, blood, and tissue, is separated. This method effectively shields the splatter and prevents obstruction of vision due to splatter adhesion.

[0018] 2. By setting up a No. 2 transparent plastic film, a tightening strap, and a fixing component, the fixing component, in conjunction with the tightening strap, can quickly fix the disposable No. 2 transparent plastic film onto the device without delaying the operation time, and after the device is fixed, it does not affect subsequent surgical operations.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0026] Example 1

[0027] Please see Figures 1-4 This embodiment provides a technical solution: a protective device against splashing during filing and sawing, comprising: a first transparent plastic film 1, a second transparent plastic film 2, a tightening strap 3, and a fixing component 4;

[0028] The main body of the protective device consists of a first transparent plastic film 1 and several sets of second transparent plastic films 2. The second transparent plastic film 2 and the first transparent plastic film 1 are shaped like a trumpet. The near end of the second transparent plastic film 2 is fitted onto the outside of the equipment, and the far end of the second transparent plastic film 2 is bent inward. The first transparent plastic film 1 is pressed and adhered to each other at the bend of the second transparent plastic film 2. The part where the first transparent plastic film 2 and the second transparent plastic film 1 are adhered is glued with a multi-point back and side adhesive material, and the far end of the first transparent plastic film 1 is bent outward.

[0029] The tensioning band 3 is located outside the second transparent plastic film 2 at one end of the device, and small teeth are opened on one side of the outer wall of the tensioning band 3. The tensioning band 3 is made of soft plastic, and the fixing component 4 is located on the outer wall of the tensioning band 3.

[0030] By placing the second transparent plastic film 2 on the device, the tightening strap 3 is rotated and wrapped around the second transparent plastic film 2 and the outside of the device. The fixing component 4 can assist the tightening strap 3 in quickly fixing it, thereby fixing the second transparent plastic film 2 to the outside of the device. The distal end of the second transparent plastic film 2 is bent and pasted to the first transparent plastic film 1. When bone fragments, blood, and tissues adhere to the first transparent plastic film 1 and affect the observation of the surgical field, the first transparent plastic film 1 is pulled. When the first transparent plastic film 1 moves, it will cause the bent end of the second transparent plastic film 2 to unfold, thereby obtaining a brand new first transparent plastic film 1 to continue to play a blocking role.

[0031] Example 2

[0032] Please see Figures 1-4 This embodiment provides a technical solution: a scraping and sawing bone anti-splash protection device, including: block 401, groove 402, groove 403, fixing rod 404, handle 405, block 406, groove 407, mounting block 408, guide rod 409, large tooth block 410, spring 411, groove 412, and elastic block 413;

[0033] The fixing component 4 includes a first block 401 integrally formed on one side of the outer wall of the tightening band 3, a first groove 402 formed inside the first block 401 and a second groove 403 that passes through and connects both sides of the first groove 402, a fixing rod 404 rotatably connected in one of the second grooves 403 by a shaft, and a handle 405 integrally formed on the outer wall of the fixing rod 404.

[0034] The second block 406 and the third groove 407, which are integrally formed on the other side of the outer wall of the tightening band 3, are connected by a shaft to a mounting block 408 inside the third groove 407. The guide rod 409, which is slidably connected inside the mounting block 408, is integrally formed to a large toothed block 410 connected to one end of the guide rod 409, and a spring 411 sleeved on the guide rod 409. The large toothed block 410 meshes with the small toothed block of the tightening band 3. The fourth groove 412 is formed on the mounting block 408 and the elastic block 413 is bonded to both sides of the inner wall of the fourth groove 412.

[0035] After the tensioning strap 3 is wrapped around the second transparent plastic film 2 and the outside of the equipment, one end of the tensioning strap 3 is inserted into the space formed by the outer wall of the tensioning strap 3 and the first block 401, the second block 406 and the mounting block 408. At this time, the tensioning strap 3 continues to move. During the movement, the tensioning strap 3 can achieve precise sealing between the second transparent plastic film 2 and the equipment. When the tensioning strap 3 moves to the designated position, the small toothed block of the tensioning strap 3 contacts the large toothed block 410 on the guide rod 409 inside the mounting block 408. At this time, the large toothed block 410 is squeezed by the spring 411, thus engaging and preventing the tensioning strap 3 from moving further after reaching the designated position.

[0036] When the second transparent plastic film 2 needs to be replaced after use, the handle 405 is used to drive the fixing rod 404 to rotate inside the second slot 403 via the shaft. During the rotation, the fixing rod 404 will no longer be inside the first slot 402. When the fixing rod 404 is no longer inside the fourth slot 412 of the mounting block 408, the elastic block 413 in the fourth slot 412 will no longer position the fixing rod 404. The mounting block 408 rotates in the third slot 407 of the second block 406. At this time, the large toothed block 410 on the mounting block 408 will no longer engage with the small toothed block of the tightening strap 3, thereby enabling the tightening strap 3 to be moved and loosened.

[0037] The implementation principle of the anti-splash protection device for filing and sawing bones in this application is as follows:

[0038] First, by placing the No. 2 transparent plastic film 2 and the No. 1 transparent plastic film 1 on the device, the tightening strap 3 is then rotated and wrapped around the No. 2 transparent plastic film 2 and the outside of the device. The fixing component 4 can assist the tightening strap 3 in quickly fixing the No. 1 transparent plastic film 1 to the outside of the device. The distal end of the No. 2 transparent plastic film 2 is bent and pasted to the No. 1 transparent plastic film 1. When bone fragments, blood, and tissue adhere to the No. 1 transparent plastic film 1 and affect the surgical field of vision, the No. 1 transparent plastic film 1 is pulled. When the No. 1 transparent plastic film 1 moves, it will cause the bent end of the No. 2 transparent plastic film 2 to unfold, thereby obtaining a brand new No. 1 transparent plastic film 1 to continue to play a blocking role.

[0039] Secondly, after the tensioning band 3 is wrapped around the second transparent plastic film 2 and the outside of the equipment, one end of the tensioning band 3 is inserted into the space formed by the outer wall of the tensioning band 3 and the first block 401, the second block 406 and the mounting block 408. At this time, the tensioning band 3 continues to move. During the movement, the tensioning band 3 can achieve precise sealing between the second transparent plastic film 1 and the equipment. When the tensioning band 3 moves to the designated position, the small toothed block of the tensioning band 3 contacts the large toothed block 410 on the guide rod 409 inside the mounting block 408. At this time, the large toothed block 410 is squeezed by the spring 411, thus engaging and preventing the tensioning band 3 from moving further after reaching the designated position.

[0040] Finally, when the second transparent plastic film 2 needs to be replaced after use, the fixing rod 404 is rotated inside the second slot 403 by the hand handle 405 through the shaft. During the rotation, the fixing rod 404 will no longer be inside the first slot 402. When the fixing rod 404 is no longer inside the fourth slot 412 of the mounting block 408, the elastic block 413 in the fourth slot 412 will no longer position the fixing rod 404. The mounting block 408 rotates in the third slot 407 of the second block 406. At this time, the large toothed block 410 on the mounting block 408 will no longer engage with the small toothed block of the tightening strap 3, thereby enabling the tightening strap 3 to be moved and loosened.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
