Problems solved by technology

This device utilizes a hospital negative pressure suction system or a conventional fat negative pressure suction device (the negative pressure value of the high negative pressure device here is 0.02-0.07Mpa), and connects the negative pressure suction system to the silica gel at the outlet of the cavity. Tube connection, so that high negative pressure is formed in the cavity and the cavity outlet, and the fat of the patient is sucked through the large-diameter liposuction tube. It solves the problem of fat cell necrosis caused by too large fat particles, and solves the problem of low ADSCs content in the obtained adipose tissue, and at the same time ensures cell activity. The experiment also found that the use of a large-diameter liposuction tube can significantly improve Clinical Liposuction Efficiency

Embodiment 1

[0031] Such as figure 1 As shown, this embodiment, as the core of the device, includes a cylinder 1, the cylinder 1 is supported on the ground by the feet 6, a cavity is formed in the middle of the cylinder 1, and a liposuction port is provided on the cylinder 1 11. Water inlet 12, negative pressure drainage port 13, fat discharge collection port 14 and sewage outlet 15, the inlet of the liposuction port 11 is connected with a large-diameter liposuction tube (φ of the large-diameter liposuction tube ≥ 4mm, side hole Caliber area S≥10mm 2 ), the negative pressure outlet 13 is connected with a high negative pressure suction pipe (the high negative pressure here is a negative pressure value of 0.02~0.07Mpa), and a fat particle cutting device is arranged in the cylinder body 1.

[0032] The fat particle cutting device includes a blade set arranged directly below the liposuction port 11 in the cylinder body 1 and a first motor 21 that drives the blade set to rotate, and the first ...

Embodiment 2

[0040] This embodiment is further improved on the basis of Embodiment 1. The cylinder body 1 is provided with a nozzle on the water inlet, and the nozzle faces the blade group. The four sides and the bottom surface of the disc 4 are filter screens and upper openings. The filter screen aperture of the collecting disc 4 is smaller than the fat particles after cutting. The bottom of the collecting disc 4 is provided with a valve through the hose line 7 and the fat discharge collection port. In communication, the negative pressure drain port 13 of the cylinder body 1 is arranged on the outer side of the collecting pan 4, not higher than the upper opening of the collecting pan 4. With this embodiment, fat particles can be cleaned while cutting large fat particles. After cleaning, blood water is drawn out from the outlet of the cavity through negative pressure, while small fat particles remain in the collection tray due to the filtering effect of the filter. Inside, the syringe can ...

Embodiment 3

[0043] This embodiment is further improved on the basis of Embodiment 2. A stirring device is provided below the collecting pan 4 in the cylinder body 1. The collecting pan 4 and the stirring device are separated by a protective net 5. The stirring device includes a The stirring blade 34 and the second motor 31 that drives the stirring blade to rotate, the second motor 31 is connected with the second rotating shaft through the second transmission device 32, the stirring blade 34 is installed on the second rotating shaft, and the first The two rotating shafts are sealed and connected with the cylinder body 1 through the second sealing member 33, and the cavity includes a cutting area, a collecting area and a stirring area sequentially from top to bottom, the fat particle cutting device is arranged in the cutting area, and the collecting plate Set in the collection area, the stirring device is set in the stirring area, so that the stirring device will stir the cut and broken fat ...

Abstract

An in-vitro fine granule fat preparation integrated machine comprises a sterile sealed cavity, an inlet and an outlet are formed in the cavity, the inlet of the cavity is connected with a large-aperture fat absorption pipe (pipe diameter is larger than or equal to 4 mm and side hole area is larger than or equal to 10 mm<2>, the outlet of the cavity is connected with a high negative pressure devicethrough a silicone tube, and a fat granule cutting device and a washing device are arranged in the cavity. The problems that fat suction is time-consuming and labor-consuming in a fat transplantationprocess, the content of fat stem cells is low and the purification process is easy to pollute are solved.

Description

technical field [0001] The invention relates to an all-in-one machine for preparing fine particle fat in vitro. Background technique [0002] Autologous fat has been widely used in clinical practice due to its rich sources, convenient material collection, no rejection, simple operation, good filling shape, no disease infection, and no scar left after surgery. Common means of wound repair. But its transplant survival rate, especially the uncertainty of long-term survival is still the main obstacle limiting its application. Improving the survival rate of transplanted fat, especially the long-term survival rate, is still an urgent problem to be solved. A large number of studies have shown that currently only 50%-80% of the volume of transplanted adipose tissue can be retained. [0003] Studies have shown that in the early stage of transplantation, adipose tissue is in a state of ischemia and hypoxia, relying on the surrounding tissue fluid to provide nutrition, fat cells sur...
