Embodiment 1

[0026] The injection molding method of embodiment 1 degradable scalpel handle:

[0027] The first step, vacuum drying: dry the degradable substrate pellets of formula 1 or formula 2 at 50°C for 3 hours in vacuum, and set aside;

[0028] The second step, injection molding: add the dried degradable substrate pellets of formula 1 or formula 2 to an injection molding machine for injection molding.

[0029] The barrel temperature is set as follows: feed inlet 160°C, compression section 165°C, metering section 175°C, nozzle 170°C;

[0030] Mold temperature: 15-20°C;

[0031] The injection pressure is: the first section is 75pa, the second section is 80Mpa, and the third section is 50Mpa;

[0032] Injection molding cycle: 43 seconds;

[0033] The holding time is: 0 seconds;

[0034] The screw speed is: 180 rpm.

[0035] Obtain the degradable scalpel handle adopting the degradable base material of formula 1 or formula 2.

Abstract

The present invention provides a degradable material for surgical knife handles and a preparation method. The degradable surgical knife handle is prepared by a degradable polymer main ingredient of a degradable substrate and an enhancer. The injection molding process includes: a feed inlet is of 155-165 DEG C, a compression segment is of 160-165 DEG C, a metering section is of 165-175 DEG C, a nozzle is of 165-170 DEG C, the mold temperature is 15-20 DEG C, the injection pressure is 75 MPa for a first grade, 80 MPa for a second grade, and 50 MPa for a third grade, the molding cycle is 43 seconds, the dwell time is 0 sec, and the screw speed is 180 rpm. The performance of the degradable surgical knife handle is in line with the requirements of national industry standard YY0175-2005 surgical knife handle, and the degradable surgical knife handle can completely replace disposable surgical knife handle made of modified polystyrene and other plastics. The waste surgical knife handle does not pollute the environment by incineration, and can completely degrade by landfilling in the natural environment to achieve low-carbon, environmental protective 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 scalpel handle and a manufacturing method. Background technique [0002] At present, the surgical knife handles used in clinical surgery in hospitals are made of metal materials such as stainless steel and disposable surgical knife handles made of ABS and other plastics. The advantages of stainless steel surgical knife handles are beautiful appearance and durability. The disadvantage is the price of metal surgical knife handles. High and repeated use, cleaning and disinfection are not only time-consuming, but also disinfection is difficult to kill viruses such as hepatitis B, so there is a hidden danger of cross-infection of diseases. "Disposable plastic scalpel handle" is made of ABS and other plastics. It is gradually accepted by clinics because of its cheap price, light weight, and portabil...
