Problems solved by technology

The application of granular fat needs to effectively remove impurities and avoid contamination during the application process. At present, centrifuge tubes are used to centrifuge the extracted adipose tissue clinically, and after centrifugation, put them into an open device and use a syringe to extract the purified granular fat For injection or other operations, it is very cumbersome to handle and has a high possibility of contamination
[0007] Therefore, it is necessary to provide a double-layer injector device for the purification of granular fat to solve the shortcomings of the existing purification methods, which are cumbersome to operate and easy to be polluted, so as to solve the technical problem of the safety of the purified granular fat after use

Abstract

The invention relates to a double-layer injector device for granular fat purification, an external injector comprises an outer tube, an external injector push rod and an external injector piston, the external injector push rod and the external injector piston are arranged in the outer tube, the external injector piston is arranged at the top end of the external injector push rod, and the external injector push rod and the external injector piston are respectively provided with an opening end; the internal injector comprises an inner tube arranged in the push rod of the external injector, a second port is formed in the top end of the inner tube, and the second port is detachably connected with the open end of the push rod of the external injector. The external injector piston and the external injector push rod are both provided with the opening ends, the second port of the internal injector is detachably connected with the opening ends and communicated with the external injector through the opening ends, the external injector is connected with the sealing cap, and the unique closed centrifugal device is formed. The method solves the technical problem that the safety of the purified granular fat after use is affected due to the fact that an existing purification mode is tedious in operation and easy to pollute.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-layer syringe device used for granular fat purification. Background technique [0002] Autologous adipose tissue has been used as a potential filler material for soft tissue defects. As a soft tissue graft material, autologous fat has obvious advantages, good biocompatibility, no rejection reaction, rich sources, simpler operation, less trauma, faster recovery, and soft and natural postoperative transplant area; at the same time, it also has the effect of shaping and slimming . [0003] In recent years, autologous fat has been widely used in clinical practice. The main indications for autologous fat cell injection and transplantation are: (1) soft tissue defects or depressed deformities on the body surface, such as congenital diseases, such as hemifacial atrophy, short hemifacial, etc.; traumatic injury, Such as soft tissue depression deformity, scar depression...
