Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical device processing, in particular to a 360-degree clamp for magnetron sputtering of bone prosthesis. BACKGROUND

[0002] The basic principle of magnetron sputtering is that magnetron sputtering is a physical vapor deposition (PVD) technology that uses the combined action of magnetic and electric fields to sputter atoms or molecules from the surface of the target material and form a thin film on the substrate surface. At present, in order to improve the better fit of bone prosthesis after being assembled to human bone, a titanium-based tantalum coating is generated on the contact surface between the bone prosthesis and the human bone by magnetron sputtering to promote the tight combination of autologous bone growth and bone prosthesis. However, since the shapes of the bone skeletons are different, it is extremely important to use a suitable clamp during the magnetron sputtering process.

[0003] The clamps used in the prior art for magnetron sputtering mainly include standard clamps for magnetron sputtering of sheet-shaped devices and standard clamps for magnetron sputtering of spherical devices, which are clamps designed specifically for certain regular-shaped devices.

[0004] At present, the clamps for common regular-shaped devices in the prior art can only be applied to devices of a certain specific shape, and the shapes of bone prostheses used in different parts are also different. Therefore, the clamps for regular devices in the prior art cannot be applied to firmly and tightly clamp bone prostheses, which can easily cause the bone prostheses to fall and be damaged during the magnetron sputtering process. Moreover, most bone prostheses are irregularly shaped objects. When 360° full-range magnetron sputtering is required on a certain specific surface, the clamps in the prior art are mostly metal clamps, which are easily attached with the materials released by magnetron sputtering during the magnetron sputtering process, causing the joints of the rotating or moving clamps to be stuck with the released materials, resulting in the clamps being stuck and unable to rotate during subsequent use. At the same time, the released materials deposited in the gap of the rotating joint are difficult to clean because they are attached to the metal clamp. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a 360-degree clamp for magnetron sputtering of bone prosthesis to solve the problem that there is no bone prosthesis magnetron sputtering clamp in the prior art that can simultaneously achieve 360° rotation of firmly and tightly clamped irregular bone prostheses and easy cleaning of the released materials in the magnetron sputtering area, resulting in the problem that the irregular bone skeletons are not firmly and tightly clamped, the bone prostheses are easily damaged during magnetron sputtering, the clamps are easily stuck with the released materials in the magnetron sputtering area, and subsequent rotation and use are difficult.

[0006] The present application is achieved by the following technical solutions:
