Handheld automatic device used for sucking and injecting fat and use method of device

Abstract

The invention discloses a handheld automatic device used for sucking and injecting fat and a use method of the device. The handheld automatic device comprises a syringe, a piston, a shell and a driving assembly, wherein the piston is connected with the interior of the syringe in a sliding mode, and the driving assembly is arranged in the shell and drives the piston; the driving assembly comprisesa power device, a flexible long shaft, a round gear rotating disc and a motor, and the flexible long shaft is connected to the end, close to the tail portion of the syringe, of the piston; the long shaft is wound on and connected with the round gear rotating disc, and the motor drives the gear rotating disc; a handheld handle is arranged at the end, away from the syringe, of the shell; the handheld handle is provided with a forward switch, a backward switch and a propulsion switch, and the advancing switch, the retreating switch and the propulsion switch are connected to the motor. The syringeis integrally connected with the shell, a driving device drives the piston so that the piston can move in the syringe in the radial direction, automatic operation can be achieved when operators suckand inject the fat, therefore fat transplantation is more precise and safer, and medical accidents in a controllable range are reduced.

Description

technical field [0001] The present invention relates to the technical field of fat transplantation, more specifically, it relates to a hand-held automatic device for suctioning and injecting fat and its application method. Background technique [0002] Fat transplantation is to suck out the excess fat in the waist, abdomen, thighs and other parts of the body. After centrifugation, purification and purification, complete fat particles are selected to improve the survival rate of fat particles. , apple muscles, cheeks and other facial filling, wrinkle removal and shaping, in order to achieve the purpose of body shaping. [0003] In the operation of fat transplantation, in order to reduce the damage to fat, many doctors use syringe liposuction to take fat.

Problems solved by technology

[0003] In the operation of fat transplantation, in order to reduce the damage to fat, many doctors use syringe liposuction to take fat. However, when using a syringe of more than 20ml for liposuction, due to the high vacuum pressure in the syringe, the hand controls the syringe lever. It is very laborious, and some small devices are needed to help block the syringe lever, but these small devices have their own advantages and disadvantages, some are inconvenient to use, some have poor results, and some are cumbersome to operate

With the continuous improvement of fat transplantation technology and awareness, there are more and more operations using large-volume fat transplantation. Syringe liposuction is recognized and used by doctors because of its light damage to fat. Fatty doctors are discouraged by liposuction, and large-volume liposuction makes doctors feel worried

[0004] Most of the existing syringe fat injection methods use a 1ml syringe for single-point uniform injection, but when the syringe is manually controlled, the single-point injection volume and continuity are affected by conditions such as the doctor's proficiency, fat purification treatment methods, and adipose fibrous tissue blockage. It will cause problems such as uneven bolus injection and fat mass accumulation, which will affect the survival rate of fat grafting surgery
