[0033] During surgical procedures, doctors frequently operate control buttons. Prolonged use and frequent keystrokes can wear out the buttons and damage internal electronic components. Furthermore, exposure of the medical handle to any one or more of high temperature, high humidity, and corrosive environments can accelerate damage to the control buttons. Regardless of the cause of control button damage, the buttons must be replaced or repaired. Existing medical handles require disassembly for button replacement or maintenance, which is complex and time-consuming.

[0034] Based on this, the utility model proposes a medical handle.

[0035] See also Figure 1 and Figure 2 In one embodiment of the present invention, the medical handle 100 includes:

[0036] The handle body 1 has a button mounting groove 12, and the button mounting groove 12 has a mounting opening 121 extending to the outer wall of the handle body 1; and

[0037] The button assembly 2 is detachably disposed in the button installation slot 12 through the installation opening 121 .

[0038] In the technical solution of the present invention, by providing a button mounting groove 12 on the handle body 1 and detachably mounting the button assembly 2 in the button mounting groove 12 through the mounting opening 121, when the control button 21 or the internal electronic components are damaged, the button assembly 2 can be replaced alone without having to disassemble the entire handle to replace the button assembly 2. This can reduce the difficulty of maintenance, improve the convenience of maintenance, and reduce the time and cost of maintenance.

[0039] Specifically, there are no specific limitations on the detachable manner of the button assembly 2 and the handle body 1; for example, they may be a snap-on connection or a threaded connection. There are no specific limitations on the shape of the button mounting groove 12; for example, they may be a circular groove or a square groove, as long as they are compatible with the button assembly 2. The specific design can be based on the shape of different button assemblies 2. It should be noted that the medical handle 100 can be a planer handle, which can be adapted to a planer blade and a grinding tool with a tissue adsorption channel. Of course, the medical handle 100 can also be a grinding handle, a milling handle, or other types of medical handles 100.

[0040] In the embodiments of the present invention, please refer to Figure 2 , the button component 2 includes:

[0041] The button 21 is inserted into the button installation slot 12; and

[0042] The positioning member 22 is detachably provided on the handle body 1 and is located on a side of the button 21 facing away from the interior of the handle body 1 so as to position the button 21 in the button installation slot 12 .

[0043] This structure uses a positioning member 22 to fix the button 21 in the corresponding position in the button mounting groove 12, preventing the button 21 from shifting during use, thereby providing a stable and reliable control experience. There is no specific limitation on the structure of the positioning member 22. For example, it can be a positioning plate or a positioning sleeve. During the process of pressing the button 21, the positioning member 22 can move synchronously with the button 21, or the button 21 can only slide inside the positioning member 22, and the positioning member 22 does not move. The detachable positioning member 22 makes the installation and replacement of the button assembly 2 easier. During installation, the button 21 and the positioning member 22 can be assembled first and then the combined structure can be installed together on the handle body 1. During disassembly, the button 21 and the positioning member 22 can be removed from the handle body 1 together and then the two can be separated. The entire disassembly and assembly process does not require the use of other complex auxiliary tools, and the replacement of the button 21 can be completed quickly.

[0044] In the embodiments of the present invention, please refer to Figure 3 and Figure 4The button assembly 2 further includes a fastener 23, through which the positioning member 22 is detachably secured to the handle body 1. The fasteners 23 are provided at each end of the positioning member 22, and are both provided on the side of the positioning member 22 facing the interior of the handle body 1. The specific detachable connection method between the fasteners 23 and the handle body 1 is not specifically limited, and may be, for example, a threaded connection or a plug-in connection. By adding the fasteners 23 to the positioning member 22, the positioning member 22 can be more securely secured to the handle body 1, ensuring that the button 21 will not become loose during operation.

[0045] Of course, the positioning member 22 can also be positioned on the handle body 1 in other ways, for example, the positioning member 22 can be threadedly connected to the handle body 1, which can also achieve a detachable connection between the positioning member 22 and the handle body 1. Specifically, the positioning member 22 can be provided with an external thread, and the button mounting groove 12 on the handle body 1 can be provided with an internal thread, so as to achieve a detachable connection between the positioning member 22 and the handle body 1.

[0046] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 The button 21 includes a pressing member 211 and a trigger switch 212. The pressing member 211 is arranged on the side of the trigger switch 212 away from the inside of the handle body 1. The pressing member 211 can operate the contact trigger switch 212. The trigger switch 212 can be an electronic device such as a touch switch. In this way, when the pressing member 211 contacts the trigger switch 212, a signal feedback will be generated, such as controlling the opening or closing of the handle, or changing the rotation, speed regulation and other operations of the tool connected to the handle. It is worth mentioning that in this button with a pressing member 211 and a trigger switch 212, the operator will not directly contact the trigger switch 212 during use. The pressing member 211 plays a certain protective role on the trigger switch 212, which is conducive to improving the service life of the button 21.

[0047] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 The button 21 further includes a protective body 213 that covers the trigger switch 212. The protective body 213 covers the trigger switch 212, so that the trigger switch 212 only contacts the pressing member 211 and does not contact other structures. This effectively prevents damage to the trigger switch 212 caused by external physical impacts, liquid splashes, etc., thereby increasing the service life of the trigger switch 212. Optionally, a sealing ring 214 is further provided between the protective body 213 and the button mounting groove 12. The sealing ring 214 can block the gap between the button mounting groove 12 and the button 21, preventing external liquids, impurities, etc. from entering the circuit cavity through the gap between the button mounting groove 12 and the button 21.

[0048] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 The button 21 has a pressing operation part 2111, which protrudes from the side of the positioning member 22 away from the handle body 1. That is to say, the upper surface of the pressing operation part 2111 should protrude from the outer surface of the handle body 1, so that the position of the button 21 is more obvious, reducing the time required to find the button 21; and, if the size of the button 21 is small, the protruding pressing operation part 2111 can avoid the situation where the downward pressure is limited due to the large thumb of the operator, and the protruding design of the pressing operation part 2111 is ergonomic, and the user experience is better.

[0049] In the embodiments of the present invention, please refer to Figure 2 The handle body 1 also has a circuit cavity 11 connected to the button mounting groove 12. A limiting step surface 10 is formed between the button mounting groove 12 and the circuit cavity 11. The limiting step surface 10 abuts against the button 21. The setting of the limiting step surface 10 can limit the button 21, so that the button 21 is more firmly fixed in the mounting groove, reducing the looseness caused by vibration, and thereby improving the accuracy of the installation position of the button 21 in the button mounting groove 12.

[0050] In the embodiments of the present invention, please refer to Figure 2 The handle body 1 also has a circuit cavity 11 connected to the button mounting groove 12. The medical handle 100 also includes a circuit board 3. The circuit board 3 is arranged in the circuit cavity 11. The button assembly 2 is electrically connected to the circuit board 3. In this way, when the circuit board 3 needs to be maintained, the circuit board 3 can be taken out through the button mounting groove 12 and the mounting opening 121 for maintenance without affecting other parts of the handle, thereby improving the maintainability of the device. Of course, this application does not rule out the use of a method of placing the circuit board 3 in the host corresponding to the medical handle 100.

[0051] In the embodiment of the present invention, the circuit cavity 11 includes a placement groove 110 for positioning the circuit board 3. When the circuit board 3 is placed in the placement groove 110, it faces the key mounting groove 12. Thus, when the circuit board 3 needs maintenance, it is only necessary to disassemble the key assembly 2. The circuit board 3 can be visually viewed through the mounting opening 121. The circuit board 3 can then be removed from the placement groove 110 through the key mounting groove 11 for maintenance, making it easier to maintain the circuit board 3. It is worth mentioning that the placement groove 110 can be formed on a component inside the handle, for example, it can be set on the outer wall of the support member 5 for winding the tool identification coil.

[0052] In the embodiments of the present invention, please refer to Figure 1 and Figure 2The circuit cavity 11 includes a wire groove 111 and a wire channel 112. The wire channel 112 is arranged along the axial direction of the handle body 1. The wire channel 112 and the button mounting groove 12 are respectively connected to the wire groove 111. The circuit board 3 is arranged in the wire groove 111. For example, the wire groove 111 may include an annular groove arranged along the radial direction inside the handle body 1, the placement groove 110 is connected to the annular groove, and the wire channel 112 is a long strip-shaped channel extending along the axial direction of the handle body 1. The combined design of the wire groove 111 and the wire channel 112 provides a clear and fixed path for the wires inside the handle body 1, making the layout of the wires inside the handle more orderly and reducing the risk of entanglement and wear between cables.

[0053] Optionally, see Figure 1 A cable assembly 4 extends from the rear end of the handle body 1. A wire is connected to the circuit board 3. One end of the wire is connected to the circuit board 3, and the other end of the wire passes through the wire groove 111 and the wire channel 112 in sequence and connects to the cable assembly 4. This hides the wires inside the handle body 1, reducing safety hazards such as short circuits and leakage caused by exposed cables. The cable assembly 4 extends toward the outside of the handle body 1, allowing the medical handle 100 to be electrically connected to an external surgical device through the cable assembly 4, thereby enabling the surgical device to control the medical handle 100.

[0054] The present invention also proposes a surgical power device, which includes a matching medical handle 100 and a medical knife. The specific structure of the medical handle 100 refers to the above-mentioned embodiment. Since the present surgical power device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. It should be noted that there is no specific limitation on the type of medical knife, for example, it can be a planer knife, etc. In addition, a surgical power device can be installed with one medical handle 100 or multiple medical handles 100, so that the operation of multiple medical handles 100 can be controlled by one surgical power device.

[0055] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
