[0032] like Figure 1-4As shown, this embodiment provides a grinding device for medical device processing, and the grinding device includes: a base 1; a clamping and rotating assembly 2, which is arranged on the base 1 and is used to connect the medical device; a movable frame 4, which is arranged on the base 1; a grinding assembly 3, which is movably arranged on the movable frame 4; wherein, the clamping and rotating assembly 2 includes a clamp motor 21, a clamp body 24 connected to the clamp motor 21 and a pair of clamping jaws arranged on the clamp body 24, the pair of clamping jaws include a lower clamping jaw 25 fixed to the clamp body 24 and an upper clamping jaw 23 movably arranged on the clamp body 24, and a locking space is formed between the pair of clamping jaws, and the medical device is at least partially located in the locking space.

[0033] Specifically, the clamping and rotating assembly 2, the movable frame 4, and the polishing assembly 3 are all installed on the base 1. During the polishing process of the medical device, the clamping and rotating assembly 2 clamps the medical device, and the polishing assembly 3 polishes the medical device while moving on the movable frame 4 to polish one surface of the medical device. The upper clamping jaw 23 moves closer to the lower clamping jaw 25 to gradually shrink the locking space, so that the medical device is fixed between the pair of clamping jaws. During the polishing process, as long as part of the medical device can be extended into the clamping space, the medical device can be clamped and polished. The stability and success rate of the clamping are both high. By providing the clamp motor 21, the clamping jaws can be rotated when needed to adapt to special-shaped medical devices, so that special-shaped medical devices can be better clamped. In addition, during the polishing process, automatic polishing can be achieved through the movable frame 4 and the polishing assembly 3, and the polishing efficiency is high.

[0034] Preferably, two clamping and rotating components 2 are provided, and the two clamping and rotating components 2 are used to better clamp the medical device. In this embodiment, the medical device includes but is not limited to a columnar device, such as an auxiliary walking device (cane, elbow cane, etc.), a roughly rectangular device, such as a rehabilitation table, etc. The above-mentioned devices will be designed with some special-shaped structures due to ergonomic considerations. The clamping and rotating components 2 can form a good clamping for these components, and realize the basis for the automated grinding of most areas of the above-mentioned medical devices. Of course, some special-shaped surfaces still need to be manually polished.

[0035] Furthermore, the polishing assembly 3 includes: a machine base 34, which is movably arranged on the mobile frame 4; a first rotary power source 31, which is arranged on the machine base 34; and a polishing piece 33, which is connected to the first rotary power source 31, and the rotary outer contour generatrix of the polishing piece 33 is at least partially in contact with the outer surface of the medical device.

The preferred clamp seat 22 is installed on the base 1 by fasteners, and its installation position can be adjusted to accommodate medical devices of different lengths.

[0037] Furthermore, the lower clamping jaw 25 and / or the upper clamping jaw 23 are provided with a clamping pad 26. The clamping pad 26 is made of elastic material to avoid damage to the medical device during the clamping process.
