Method for manufacturing total auditory ossicle prosthesis

Abstract

The invention discloses a method for manufacturing total auditory ossicle prosthesis. The method is characterized by comprising the following steps of: manufacturing a model prosthesis of a total auditory ossicle by adopting a titanium material, wherein the model prosthesis consists of a mesh end and a strip handle, the mesh end is a rectangular slice provided with a circular hole, and the strip handle and the mesh end are in 'L'-shaped right-angled connection; and after the model prosthesis is adaptively regulated and corrected, correcting the geometric dimension of a standard prosthesis of the total auditory ossicle so that the standard prosthesis and the model prosthesis of the total auditory ossicle are totally matched. Compared with the prior art, the method greatly avoids and reduces standard prosthesis waste caused by over correction, greatly saves the surgery cost, and has simple manufacture and good adaptability.

Description

technical field [0001] The invention relates to the technical field of artificial organs, in particular to a method for making a total ossicle prosthesis. Background technique [0002] In the 1950s, the ossicle prosthesis implanted in the middle ear was made by hand using materials that were considered harmless at the time. For example, Schacknecht used stainless steel wire to wrap a group of earlobe fat to replace the excised stapes. Ossicular prostheses made of vinyl or Teflon. This kind of prosthesis has good biocompatibility, the rejection rate is very small, the material is not expensive, and the amount of the prosthesis made is very small (only a few grams), and the cost of hand-made by the surgeon is almost no cost. As long as the design of this type of ossicle prosthesis is reasonable, easy to manufacture and suitable for implantation, the success rate of the operation is quite high, and the complications are also very low. It is generally used in the operation of o...

AI Technical Summary

Problems solved by technology

[0003] Today, the production of ossicle prostheses is produced by companies certified by the state or FDA using certain technical specifications and requirements. The safety and quality of these standard prostheses are fully guaranteed, but the prices are relatively expensive. In our country, the cost of ossicle prosthesis is negligible compared to more expensive surgery fees. In our country, the doctor's surgery fee is relatively low, but the cost of an imported full ossicle prosthesis is almost equal to or More than one surgery fee or several times the surgery fee

Since the length of the ossicle prosthesis varies from person to person, different corrections need to be made according to individual differences. Because the correction results are not always as expected, the over-corrected ones can only be discarded and replaced with new prostheses. It is so easy Cause waste and increase the burden of surgery costs
