Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical power handle and surgical power device. Background Technology

[0002] In the field of minimally invasive medical devices, some medical powered handpieces are adapted to disposable cutting tools, allowing the energy output from the built-in power source to be transferred to the tool, enabling the tool to perform operations such as planing, grinding, milling, or drilling on human tissue. To ensure the safety and accuracy of the surgery, the cutting tool mounted on the powered handpiece needs to be identified; a common method is to install an identification coil inside the powered handpiece.

[0003] For traditional medical power handpieces with recognition functions, there is a large axial gap between the recognition coil and the motor inside the handpiece housing. The overall length of the handpiece is relatively long, resulting in a heavy handpiece. Doctors are prone to fatigue during surgical operations, which is not conducive to doctors holding the handpiece for a long time to perform surgical operations. Utility Model Content

[0031] For traditional medical power handpieces with recognition functions, there is a large axial gap between the recognition coil and the motor inside the handpiece housing. The overall length of the handpiece is relatively long, resulting in a heavy handpiece. Doctors are prone to fatigue during surgical operations, which is not conducive to doctors holding the handpiece for a long time to perform surgical operations.

[0032] This utility model proposes a medical power handle.

[0033] Please see Figure 1 In one embodiment of this utility model, the medical power handle 100 includes:

[0034] The handle body 1 has a cavity extending along its own axial direction;

[0035] Identification component 2 is fixedly installed inside the cavity, and identification component 2 has an internal space that runs through the front and back; and

[0036] The motor assembly 3 is fixedly installed inside the cavity and has an output section for connecting to the tool drive;

[0037] The identification component 2 is located adjacent to the front of the motor component 3, and its internal space is designed to include a tool mounting space, with the output part extending into the internal space.

[0038] The technical solution of this utility model arranges the identification component 2 and the motor component 3 adjacently, greatly reducing the axial distance between them. The internal space of the identification component 2 is effectively utilized to accommodate a part of the tool (such as the interface section, connecting section, or part of the working section of the tool). At the same time, the output part of the motor component 3 can extend into the internal space to drive the tool. The space inside the cavity can be fully utilized, thereby shortening the overall length of the handle body 1 in the axial direction. A shorter handle means better operational flexibility and accessibility, which helps to reduce the fatigue of doctors during long-term surgical operations.

[0039] Specifically, the handle body 1 can be made of plastic or metal, and the cavity can be a channel extending along the length of the handle, which fits with the recognition component 2 and the motor component 3 with clearance for easy assembly. Optionally, the rear end of the cavity has a closable opening with a step or chamfer to guide the motor component 3 and the recognition component 2 into the cavity. Furthermore, the inner wall of the cavity can also have multiple mounting bosses or limiting steps to accurately define the installation positions of the motor component 3 and the recognition component 2. The recognition component 2 can be a housing with a hollow cylindrical or square internal space. The output part of the motor component 3 can mate with the tool connector extending into the internal space. For example, when the tool is a planer, the inner tube connector of the planer is located at the rear end of the outer tube connector and connects to the output connector of the motor component 3. The inner tube of the planer is directly connected to the inner tube of the rotor of the motor component 3. This means that part of the docking structure between the motor component 3 and the planer is located in the internal space, making the internal structure of the entire handle body 1 compact.

[0040] In the embodiments of this utility model, please refer to Figure 1 The medical power handle 100 also includes a first sealing structure 4, which is disposed between the motor assembly 3 and the identification assembly 2 to seal the gap between the identification assembly 2 and the motor assembly 3.

[0041] In some possible implementations, the first sealing structure 4 can be an O-ring, V-ring, U-ring, Y-ring, rectangular ring, etc. Regardless of the type of sealing ring used, when the sealing ring is compressed, it will produce elastic deformation, filling the gap between the motor assembly 3 and the identification assembly 2, thereby achieving a seal.

[0042] In the embodiments of this utility model, please refer to Figure 2The first sealing structure 4 includes a sealing gasket 41, and the identification component 2 includes a coil frame 21 and an identification coil 22. The coil frame 21 is disposed in the cavity, and the internal space is formed on the coil frame 21. The identification coil 22 is wound around the outer periphery of the coil frame 21. A pressing part 211 protrudes from the end of the coil frame 21 near the motor assembly 3. The sealing gasket 41 is pressed into the gap between the pressing part 211 and the motor assembly 3. Alternatively, the pressing part 211 can also protrude from the end of the motor assembly 3 near the coil frame 21, and the sealing gasket 41 can be pressed into the gap between the pressing part 211 and the coil frame 21.

[0043] The coil frame 21 can be cylindrical, and a groove can be provided on the length direction of the outer peripheral surface. The groove can be a continuous spiral groove for fixing the wiring of the identification coil 22, or it can be multiple annular grooves arranged at intervals. A wire hole or wire groove is provided between adjacent annular grooves so that the identification coil 22 can be wired around the adjacent previous annular groove and then enter the next annular groove through the wire hole or wire groove.

[0044] Furthermore, a clamping part 211 is provided at the rear end of the coil frame 21 (the end near the motor assembly 3) or the front end of the motor assembly 3 (the end near the coil frame 21). The sealing gasket 41 is confined within the gap between the clamping part 211, the motor assembly 3, and the coil frame 21, and its position is fixed, making it difficult to shift or rotate. The clamping part 211 directly applies pressure, ensuring tight contact between the sealing gasket 41 and the motor assembly 3. Compared to the traditional method of sealing with a sealing ring, this method uses the clamping part 211 to pressurize the sealing gasket 41 during assembly, ensuring that the sealing gasket 41 can deform to a greater extent, thereby forming a more reliable sealing structure. Optionally, the clamping part 211 is an annular protrusion, and the sealing gasket 41 is an annular sealing gasket.

[0045] Optionally, the abutting part 211 is a structure that protrudes outward from the rear end of the coil frame 21. It can be a protrusion with a specific contour (such as an arc shape). The arc shape can increase the contact area with the sealing gasket 41 and achieve a more effective seal.

[0046] In the embodiments of this utility model, please refer to Figure 2The identification component 2 has a receiving groove 5 near the end of the motor component 3 and / or the end of the motor component 3 near the identification component 2, and the sealing gasket 41 is disposed in the receiving groove 5. In this embodiment, at the position where the identification component 2 and the motor component 3 abut against each other, the receiving groove 5 can be provided on one of the two contact ends (the end face of the motor component 3 or the end face of the identification component 2), or a portion of the receiving groove 5 can be provided on each of the two end faces, to provide a preset, precisely limited installation space for the sealing gasket 41, preventing displacement during installation or use. Optionally, a retaining ring can also be provided around the opening of the receiving groove 5 to prevent the sealing gasket 41 from falling out of the receiving groove 5.

[0047] In the embodiments of this utility model, please refer to Figure 2 The receiving groove 5 is located at the end of the motor assembly 3 near the identification component 2. At least a portion of the pressing part 211 extends into the receiving groove 5 and abuts against the sealing gasket 41. In this embodiment, the receiving groove 5 is provided on the end face of the motor assembly 3 near the identification component 2. The receiving groove 5 can be an annular or rectangular groove. The sealing gasket 41 is an annular ring fitted around the outer periphery of the motor assembly 3. The depth and width of the receiving groove 5 are slightly larger than the size of the sealing gasket 41 so that the sealing gasket 41 can be smoothly inserted and leave appropriate compression space. The pressing part 211 can extend entirely or partially into the receiving groove 5 to press the sealing gasket 41. In this embodiment, the shape of the pressing part 211 is not specifically limited; for example, it can be square or arc-shaped.

[0048] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The end of the clamping part 211 that abuts against the sealing gasket 41 is configured with an arc-shaped structure. In this embodiment, the clamping part 211 is arc-shaped, for example, it can be hemispherical or ellipsoidal. This can concentrate the pressure of the clamping part 211 on the sealing gasket 41 in a relatively small area, resulting in greater deformation of the sealing gasket 41. Furthermore, the arc-shaped clamping part 211 avoids local stress concentration that may be caused by sharp edges or flat surfaces, thus preventing the sealing gasket 41 from being damaged due to excessive local force.

[0049] In the embodiments of this utility model, please refer to Figure 2The identification component 2 includes a coil frame 21 and an identification coil 22. The coil frame 21 is disposed within a cavity, and the internal space is formed on the coil frame 21. The identification coil 22 is wound around the outer periphery of the coil frame 21. The medical power handle 100 also includes a second sealing structure 6, which is disposed between the cavity wall and the coil frame 21 and located in front of the identification coil 22. The second sealing structure 6 can be an O-ring or a lip seal, etc., which creates pre-compression between the cavity wall and the outer wall of the coil frame 21. This not only forms a sealing barrier from the front area of ​​the identification coil 22 to prevent external contaminants from intruding into the identification coil 22 and its surrounding area, but also provides a certain radial support and positioning effect for the coil frame 21.

[0050] In the embodiments of this utility model, please refer to Figure 2 A sealing groove 7 is provided on the inner wall of the handle body 1 or the outer wall of the coil frame 21. The second sealing structure 6 is disposed in the sealing groove 7 to seal the gap between the cavity wall and the outer wall of the coil frame 21. For the installation of the second sealing structure 6, the sealing groove 7 can be provided at the position on the outer periphery of the coil frame 21 (in front of the identification coil 22), or the sealing groove 7 can be provided at the corresponding position on the cavity wall. The sealing groove 7 can be an annular groove or multiple discontinuous grooves joined together, so that the second sealing structure 6 is embedded in the sealing groove 7 and compressed to fill the gap in the sealing groove 7 to form a seal.

[0051] This utility model also proposes a surgical power device, which includes a medical power handle 100 as described in any of the above embodiments and a cutting tool adapted to the medical power handle 100. The specific structure of the medical power handle 100 is as described in the above embodiments. Since this surgical power device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. It should be noted that the type of medical cutting tool is not specifically limited, for example, it can be a planing tool, a grinding tool, etc.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
