[0035] In the technical solution of the present invention, the handle housing 1 includes a housing body 11 and an end cap 12. A first through hole 121 is provided in the end cap 12, allowing the extension 211 of the motor assembly 2 to extend through the first through hole 121. A locking member 3 is provided on the outer periphery of the extension 211. The locking member 3 is positioned with the extension 211 and abuts against the outer side of the end cap 12, thereby forming a stable connection between the end cap 12 and the handle housing 1. Through the detachable connection between the locking member 3 and the extension 211, the end cap 12 is firmly pressed against the housing body 11 by the locking member 3. This installation method of the end cap 12 replaces the existing threaded connection method of the end cap 12 and the housing body 11. The shape of the end cap 12 is no longer limited to a circular shape, and can be adapted to a variety of end caps 12 shapes, thereby increasing the flexibility and adaptability of the design of the medical handle 100, thereby enabling the medical handle 100 to be adapted to a wider variety of medical instruments. Specifically, in this embodiment, the provision of the extension 211, the locking member 3, and the first through-hole 121 on the end cap 12 facilitates a removable connection between the end cap 12 and the handle housing 1. This solves the problem of the existing threaded connection between the end cap 12 and the handle housing 1, which requires the end cap 12 to be circular. This expands the designability of the end cap 12, allowing it to be shaped in any other manner, such as square, elliptical, or trapezoidal. It should be noted that the end cap 12 can be directly attached to the rear of the housing body 11 or connected to the housing body 11 via other structures, such as a light-transmitting shell disposed between the end cap 12 and the housing body 11. Furthermore, the shape of the first through-hole 121 is not specifically limited and can be, for example, circular or triangular, as long as it is compatible with the extension 211 of the motor assembly 2. It should be noted that the medical handle 100 described above can be a planer handle, which can be adapted to planer blades and grinding tools with tissue adsorption channels.

[0037] In the embodiments of the present invention, please refer to Figure 2 The first through hole 121 is a countersunk hole, which includes small holes and large holes arranged in sequence from front to back, so that the locking sleeve can sink into the large hole more firmly, thereby enhancing the connection stability between the handle housing 1 and the end cover 12, and reducing the shaking and displacement that may occur during use.

[0038] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The medical handle 100 also includes a cable assembly 4. A second through hole 122 is provided on the end cover 12, and the cable assembly 4 passes through the second through hole 122. The setting of the second through hole 122 provides a fixed path for the cable assembly 4, and can maintain the orderliness of the cable assembly 4, avoiding the safety hazards caused by the scattered cable assembly 4. In this embodiment, there is no specific limitation on the shape of the second through hole 122. For example, it can be circular or triangular, etc., as long as it can fix the cable assembly 4. In this way, the first through hole 121 and the second through hole 122 are respectively provided on the end cover 12, so that the extension 211 of the cable assembly 4 and the motor assembly 2 are both connected to the end cover 12, which further improves the connection stability of the end cover 12, and is also conducive to simplifying the arrangement of components on the handle housing 1 and reducing production costs.
