Degradable material for tubal extraction hook and manufacturing method

Abstract

The present invention provides a degradable material for tubal extraction hooks and a manufacturing method. The degradable material is prepared by polymer main ingredient of a degradable substrate and an enhancer. The injection molding process includes that: a feed inlet is of 150-165 DEG C, a compression segment is of 160-170 DEG C, a metering section is of 160-175 DEG C, a nozzle is of 165-175 DEG C, the mold temperature is 20-45 DEG C, the injection pressure is 45-85 Mpa, the injection time is 40-55 seconds, the dwell time is 0 sec, and the screw speed is 180 rpm. The performances of the degradable tubal extraction hook are in line with the requirements of national industry standard YY91024 1999. The degradable tubal extraction hook can completely replace a metal tubal extraction hook. The waste degradable tubal extraction hook does not pollute the environment by burning, and can completely degrade by landfilling in the natural environment. The degradable tubal extraction hook is especially suitable for disposable use, and helps to prevent iatrogenic disease cross-infection and achieve environmental-protection and energy-saving purposes.

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.
