Low-temperature granular fat collecting device for fat transplantation

Abstract

The invention discloses a low-temperature granular fat collecting device for fat transplantation. The device comprises two parts, namely, a cylindrical outer housing and a cylindrical inner housing, wherein a cold water chamber for storing cooling water is formed between the outer housing and the inner housing; a water feeding port and a water draining port are correspondingly formed in the upper part and the bottom part of the outer housing; the inner housing consists of an upper cover and a lower barrel body; the upper end surface of the upper cover is provided with an absorbing port which communicates with a negative pressure system, a fat inlet which is connected to a liposuction tube, and a fat extracting port which is connected to a fat extracting needle and is provided with a blocking plug. With the adoption of the device, cooling water can be separated from an operation performing table environment, and the cooling water can be stored in the cold water chamber formed between the outer housing and the inner housing; the granular fat obtained by a small-diameter liposuction tube in a sterile and low-negative-pressure condition and other conditions is stored in the sterile low-temperature environment, so that the granular fat can remain good activity, and as a result, the convenience of transplantation operation can be ensured, and the survival rate of fat tissue can be increased after the operation. The device has the characteristics of being easily clinically operated, easily cleaned and disinfected, and capable of being repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of medical cosmetology, and relates to an autologous fat transplantation technology, in particular to a device for collecting fat particles at low temperature for fat transplantation. Background technique [0002] Autologous fat transplantation technology is a method of liposuction and body shaping. It is different from weight loss liposuction. It simply reduces weight during weight loss and makes the body healthy. Body sculpting liposuction performed by autologous fat transplantation technology is to sculpt the body, followed by weight loss. Sometimes even the body weight does not change, but the body is more perfect. [0003] At present, granular fat transplantation, as a commonly used surgical treatment in plastic surgery, has been widely used in soft tissue augmentation and regeneration for plastic repair and cosmetic purposes. In order to ensure that the obtained fat particles have uniform size, comple...

Problems solved by technology

[0007] Based on the above reasons, in order to meet the smooth completion of autologous fat transplantation technology and solve the problems of aseptic collection and short-term cryopreservation of transplantable fat particles, the present invention provides a special method for sucking out fat particles during liposuction in fat transplantation surgery. The device for low-temperature aseptic collection of the obtained fat particles effectively solves the above-mentioned problems in the existing transplanted fat particle preservation technology
