Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a split-type power handle. Background Technology
[0002] In surgical procedures, powered devices (such as bone drills or bone saws) are often used to drill or cut bone tissue. A powered device typically includes a power handle and a cutting tool connected to the handle. The cutting tool is usually mounted at the front of the power handle, and the power supplied by the handle drives the tool to move and process the bone tissue.
[0003] To drive and control the movement of the cutting tool, the power handle contains electronic components such as a motor, reducer, circuit board, and signal recognition system. These components require electrical connections. Existing power handles directly assemble the electronic components within the handle housing and then seal them in their respective locations. However, the power handle requires complete sterilization before use. If the electronic components are not properly sealed, water may enter during the sterilization process, potentially damaging the power handle's functionality. Utility Model Content

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0028] It should be understood that this invention can be embodied in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of this invention to those skilled in the art. In the drawings, the same reference numerals denote the same components throughout.
[0029] The specific structure of the split-type power handle in this utility model is described in conjunction with [reference needed]. Figures 1 to 3 The split-type power handle includes a handle housing 10; the handle housing 10 includes:
[0030] First shell 11;
[0031] The second housing 12 is fastened and fixed to the first housing 11. After the first housing 11 and the second housing 12 are fastened together, they form an enclosing cavity. The front end of the enclosing cavity has a through hole 13 that communicates with the outside of the handle housing 10.
[0032] A sealing sleeve 20 is fitted inside the containment cavity. An electronic drive assembly is sealed inside the sealing sleeve 20. The output part 32 of the electronic drive assembly extends to the front end of the handle housing 10 through the through hole 13.
[0033] In actual implementation, when manufacturing the split-type power handle, the electronic drive component can be pre-equipped in the sealing sleeve 20. After assembly, the sealing sleeve 20 is sealed around its perimeter. Then, the sealing sleeve 20 is placed in the containment cavity, and the first housing 11 and the second housing 12 are fastened together to complete the assembly of the split-type power handle.
[0034] The electronic drive components required for the power handle are assembled within the sealing sleeve 20. The sealing sleeve 20 encloses and seals all electronic drive components, effectively integrating them. The parts of the electronic drive components that are needed extend outside the sealing sleeve 20, allowing for normal operation and electrical connection. The sealing sleeve 20 is then housed within the containment cavity, restricting its movement and thus assembling all electronic drive components. During use, this power handle can be disinfected comprehensively, even by immersion. Because the sealing sleeve 20 seals and protects the electronic drive components, damage from disinfectant is prevented, ensuring the power handle remains undamaged.
[0035] In some embodiments, the sealing sleeve 20 is a hollow tubular structure, with a front end cap 21 detachably provided at its front end and a rear end cap 22 detachably provided at its rear end. For example, Figure 2 , Figure 3 As shown, the tubular sealing sleeve 20 facilitates the installation of the electronic drive assembly. The front cover 21 and the rear cover 22 facilitate the assembly of the electronic drive assembly and, on the other hand, facilitate the sealing of the electronic drive assembly inside the sealing sleeve 20 after the electronic drive assembly is assembled.
[0036] In some embodiments, both the front end cover 21 and the rear end cover 22 are threadedly connected to the sealing sleeve 20, and the threaded connection is sealed with thread sealant. After the electronic drive assembly inside the sealing sleeve 20 is placed, the front end cover 21 and the rear end cover 22 are threadedly connected to the sealing sleeve 20, and thread sealant is used to seal the connection during the threaded connection.
[0037] In some embodiments, the front end cap 21 and / or the rear end cap 22 facing the handle housing 10 have an anti-rotation portion 23, and the front end and / or rear end of the containing cavity are provided with anti-rotation components that cooperate with the anti-rotation portion 23. The anti-rotation portion 23 and the anti-rotation component cooperate to prevent the sealing sleeve 20 from rotating circumferentially within the containing cavity. Since the sealing sleeve 20 is a tubular structure, the sealing sleeve 20 is placed within the containing cavity and can cooperate with the anti-rotation portion 23 and the anti-rotation component to ensure that the sealing sleeve 20 does not rotate circumferentially after assembly, thus facilitating the normal operation of the electronic drive assembly.
[0038] In some embodiments, a plurality of anti-rotation portions 23 are arranged circumferentially along the front end cover 21 or the rear end cover 22, and the number of anti-rotation members corresponds to the number of anti-rotation portions 23, wherein the anti-rotation members prevent the anti-rotation portions 23 from rotating circumferentially. For example, Figure 3 As shown, the anti-rotation part 23 is provided on the rear end cover 22, and an anti-rotation component is correspondingly provided on the inner wall of the containment cavity. The anti-rotation component can be a protrusion that locks the anti-rotation part 23, thereby restricting the circumferential rotation of the sealing sleeve 20. Specifically, the anti-rotation part 23 is also provided on the front end cover 21, and an anti-rotation component that can lock the anti-rotation part 23 is also provided on the front side of the containment cavity.
[0039] In some embodiments, the sealing sleeve 20 has a plurality of cable holes 24 on its cylindrical wall. The cables of the electronic drive assembly extend out of the sealing sleeve 20 through the cable holes 24 and the cable holes 24 are sealed with sealant. For example, Figure 3 As shown, in order to facilitate the electrical connection of the electronic drive components, a cable hole 24 is provided on the sealing sleeve 20. After the cable passes through the cable hole 24, it can be sealed with electronic sealant.
[0040] In some embodiments, a plurality of support ribs 14 are provided on the inner wall of the central portion of the containing cavity. The support ribs 14 are spaced apart along the axial direction of the containing cavity to limit the sealing sleeve 20 in the axial direction. For example, Figure 2 As shown, in order to install the sealing sleeve 20 in the containment cavity and reduce vibration and shaking, a support rib 14 is provided to tighten and limit the position of the sealing sleeve 20.
[0041] In some embodiments, the electronic drive assembly includes a drive module 30, a reduction module 31 connected to the drive module 30, an output section 32 connected to the reduction module 31, and an identification module 33 disposed at one end of the output section 32. Each of the electronic drive components is arranged sequentially from back to front inside the sealing sleeve 20. For example, Figure 2 , Figure 3As shown, the drive module 30 can provide output power to the power handle, and the output part 32 extending from the front end of the sealing sleeve 20 is provided with a tool chuck 34, which is used to hold the tool.
[0042] In some embodiments, one end of the output portion 32 is located inside the sealing sleeve 20, and the other end of the output portion 32 extends out of the sealing sleeve 20 through the sealing sleeve 20. The sealing sleeve 20 and the output portion 32 are sealed together by a sealing ring 25. For example, Figure 3 As shown, in order to completely seal the electronic drive component within the sealing sleeve 20, a sealing ring 25 is used to seal the output part 32 where it extends out of the sealing sleeve 20.
[0043] In some embodiments, the first housing 11 and the second housing 12 are provided with a plurality of screw holes 15 at corresponding positions, and the first housing 11 and the second housing 12 are fixedly connected by screws and the screw holes 15. For example, Figure 1 , Figure 2 As shown, after the first housing 11 and the second housing 12 are fastened together, screws are screwed into the screw holes 15 to make the first housing 11 and the second housing 12 firmly connected.
[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
