Suture Screw Anchor

Metal micro injection molding (μMIM) is a forming technology developed by the German IFAM Institute, which is to organically apply MIM technology to the preparation of micron-sized parts.

In general, there are two types of products that μMIM can be used to produce:

① Parts with a size of micron level and a mass as light as a few milligrams;

② The appearance size of the part is similar to the size of the traditional injection molding part, but the size of the local structure reaches the micron-level part with a microstructure.

In recent years, micro-injection molding has become a research hotspot in the field of injection molding. With the development of modern machinery towards miniaturization, the application of micro-injection molding will become more and more extensive.

At present, Qinhuangdao Zhongwei Precision Machinery Co., Ltd. and the Research Center of Central South University have successfully applied μMIM technology to the production of tiny parts of medical devices, such as spectrometers, titer plates, etc. The structure size of the products has reached the micron level, and the minimum wall thickness is 50μm.

The suture anchor for surgical use produced by Qinhuangdao Zhongwei Precision Machinery Co., Ltd. using μMIM technology is only the size of a match head.

Open reduction and anchoring of temporomandibular joint disc is a surgical procedure for the treatment of irreversible anterior displacement of temporomandibular joint disc. Due to the special operation site, anchoring screws and anchoring wires are used in this operation to connect the temporal bone and the jaw. bone. The existing anchoring nail consists of two parts: a nut and a screw. The part of the nut protrudes from the bone surface after surgery. An anchor wire is tied at the connection between the nut and the screw for connection and fixation. The nut of this type of anchoring nail will compress to other surrounding tissues, which is not conducive to the recovery of patients after surgery. At present, there is another kind of anchoring nail with the nut inside the screw. Although this type of anchoring nail solves the problem of the nut compressing the surrounding tissue, it is very inconvenient to use, and it is difficult for doctors to tie the anchoring wire to the concave screw cap.

The Chinese utility model patent "Medical Anchoring Nail" discloses an anchoring nail comprising a nut and a screw rod. The nut of the anchoring nail is provided with a groove along its outer circumference toward its center. When in use, the nut protrudes from the bone. On the other hand, the anchoring wire is tied to the groove of the screw cap, which is convenient to use, but the protruding screw cap compresses other surrounding tissues, which is not conducive to the recovery after the wound. The Chinese utility model patent "A Medical Anchoring Nail" discloses an anchoring nail with the nut located inside the screw. Although the anchoring nail solves the problem that the nut is exposed and compresses the surrounding tissue during anchoring, it is difficult to tie the anchoring wire inside. on the sunk nut.

Often, ruptured tendons are repaired by implanting bone anchors made of titanium, allowing the fracture to heal - but the titanium pins must then be removed. The new implants are made of iron tricalcium phosphate, which is biodegradable despite being made of metals and ceramics. Over time -- two years, actually -- they just break down into your body. Ceramic ingredients can even stimulate bone growth to encourage your body to fill in the holes they leave behind. Not that these will ease the pain of tendon ruptures.
