Problems solved by technology

[0005] ① Autologous fat granule harvesting currently lacks a method for evaluating the activity of fat granules. Therefore, in the current process of fat granule harvesting, the damage to fat granules caused by various factors such as uneven pressure is a blind process.
The main problems in this process are that the exposure operation is easy to produce pollution, the hand injection pressure is uneven, and the fat particles are easy to be damaged.
At the same time, due to the different sizes of fat particles and large changes in resistance, it is difficult to control the amount of manual injection, and local excessive injection may easily cause necrosis, liquefaction and other problems

Embodiment Construction

[0027] The detailed description and technical content of the present invention are now described as follows in conjunction with the accompanying drawings: at first referring to Fig. 1, Fig. 1 is a schematic structural view of an embodiment of the present invention, in this embodiment, the autologous fat transplantation device is divided into three Part, fat acquisition instrument 1, fat screening instrument 2 and fat particle injection instrument 3. Among them, the fat harvesting instrument 1 is a negative pressure extraction tube, which extracts the fat particles through the optimal expansion pressure, negative pressure and the setting of the suction tube diameter, and passes through the gap between the fat acquiring instrument 1 and the screening instrument. The negative pressure or peristaltic pump 4 injects the obtained particles into the screening instrument. The screening instrument removes liquid oil through adsorption materials, and removes blood clots, thick fiber str...

Abstract

An auto-fat transplanting apparatus is composed of negative- pressure sucking tube, container with internal multi-tooth comb shaped rotary rod, laminar flow separator, dewatering device, injection tube, sealed connecting tube and pump. Its fat particles screening method for purifying and separating fat particles to make Them have higher activity is also disclosed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an autologous fat transplantation device and a method for screening fat particles based on the device. Background technique [0002] Clinical autologous fat transplantation mainly refers to the existence of depressions on the body surface or insufficient or asymmetric local tissue volume. By extracting fat from other parts of the body, it is transplanted to the insufficient or depressed parts to achieve therapeutic purposes. It generally includes the following steps: ①The acquisition of autologous fat is through the expansion method, that is, a large amount of liquid containing local anesthetics and angiotensin is injected into the subcutaneous fat layer to disperse and dissociate the fat particles, and then the fat particles are removed through a negative pressure suction tube. The fat particles are sucked out of the body; ②The aspirated fat particles are cleaned to remove impurit...
