Degradable material and preparation method for fallopian tube extraction hook

Abstract

The invention provides a degradable material for a fallopian tube extraction hook and a preparation method. It is made of polymer main material and reinforcing agent of degradable base material. Its injection molding process is: feed inlet 150-165°C, compression section 160-170°C, metering section 160-175°C, nozzle 165-175°C ;Mold temperature: 20-45°C; injection pressure: 45-85Mpa; injection time: 40-55 seconds; holding time: 0 seconds; screw speed: 180 rpm. The properties of the obtained degradable fallopian tube extraction hook meet the requirements of the national industry standard YY91024-1999, and can completely replace the metal fallopian tube extraction hook. After the fallopian tube extraction hook is discarded, it does not need to be incinerated and will not pollute the environment. It can be buried in the natural environment Fully biodegradable, especially suitable for one-time use, not only to avoid cross-infection of iatrogenic diseases, but also to achieve the purpose of environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the field of environment-friendly, energy-saving and degradable disposable medical devices, in particular to a degradable material for a fallopian tube extraction hook and a manufacturing method. Background technique [0002] The fallopian tube extraction hook is clinically used by the family planning department to extract the fallopian tubes for female fallopian tube ligation. At present, most of the fallopian tube extraction hooks are made of metal materials such as stainless steel. Repeated use can easily cause cross-infection of diseases, and patients will feel very cold when using them in winter. Disposable fallopian tube extraction hooks made of plastics such as ABS are also available. The disposable medical devices produced are basically processed by centralized incineration, which pollutes the environment. Therefore, research and development of degradable disposable fallopian tube extraction hooks can not only avoid the...

Problems solved by technology

At present, most of the fallopian tube extraction hooks are made of metal materials such as stainless steel. Repeated use can easily cause cross-infection of diseases, and patients will feel very cold when using them in winter. Disposable fallopian tube extraction hooks made of plastics such as ABS are also available. The disposable medical devices produced are basically processed by centralized incineration, which pollutes the environment. Therefore, research and development of degradable disposable fallopian tube extraction hooks can not only avoid the repeated use of metal fallopian tube extraction hooks to prevent cross-infection of iatrogenic diseases, but also Avoid the disadvantages of polluting the environment when the plastic disposable fallopian tube extraction hook is incinerated, and because the degradation substrate polylactic acid has many advantages of good biocompatibility, it will gradually replace disposable medical devices made of stainless steel and petroleum-based plastics

But so far, there is no research and report on degradable materials and preparation methods for fallopian tube extraction hooks at home and abroad.
