Abstract

A quantitative transplanting device for self purified fat according to the utility model relates to the field of a self fat transplanting shaping surgery device, and is particularly suitable for small-amount and fixed-amount fat transplanting in the self fat transplanting shaping surgery, acts for separating fat from the liquid except for the fat and implanting the purified fat. According to the quantitative transplanting device, a needle pipe is provided with the following components: obtuse head fat suction needles with various geometrical holes, a syringe barrel, a piston, a piston connecting head, a negative pressure adjusting hole, a handle, a piston sealing ring, a filtering net, and a connection port which can be connected with the air pipes with different hole diameters according to different connection modes. According to the quantitative transplanting device for the self purified fat, a mode of generating negative pressure through the syringe for sucking fat is changed, and a negative pressure device is used for providing the negative pressure; the fat suction needles are directly inserted into fat suction parts of the human body. After the fat is separated from the human body, the fat enters the syringe barrel. Under negative pressure function, after fat-water mixture in the needle barrel passes through the filtering net, the fat remains in the needle barrel, and other liquid is separated from the fat after connecting a connecting pipe opening of the negative pressure pump with a negative pressure pipe. The purified fat is directly transplanted to a required position. Therefore the following functions are obtained: reduced time and labor, high safety, and high effectiveness.

Description

From purification Fat quantification grafting device

Technical field

This utility model relates to autologous fat transplantation plastic operation apparatus field, is specially adapted to a small amount of in the autologous fat transplantation plastic operation, quantitatively fat transplantation, act on the fluid separation applications beyond fat and fat and purify after fat implant.

Background technology

Often fill the human body rejected region with foreign bodies such as silica gel in existing body is moulding, discharges because the toxicity of chemical substance is recessive, by long-time demonstration and both at home and abroad to the research of implant, its poisonous implant in use forms potential safety hazard.By contrast, autologous fat transplantation just possessed without repel, the affine advantage that by force, easily survives, more can reach fat-reducing and moulding dual purpose.The main dual mode that adopts in similar Surgical Operation in the past: a kind of is to be used in conjunction with liposuction machine and centrifuge, at first with the liposuction machine, fat is extracted out, re-uses centrifuge and implants after with fluid separation applications such as fat and water.The fat mass that this kind mode is taken out is large, and unnecessary fat goes out of use substantially, simultaneously in using the centrifuge process, the fat of extracting out is exposed in air, after packing with centrifuge high speed decentraction rotation, the long and centrifugal destruction due to process, cause fat transplantation after survival rate not high; Another way is to utilize injector syringe and piston to produce negative pressure by pumping rod in syringe when extracting a small amount of fat, then extracts fat by the fat suction needle liposuction.Be difficult to so disposable extraction requirement fat, and the fat of releasing is purified complicated.The fat inner blood, fill liquid, anaesthetic is residual all must rely on filtered through gauze or by the centrifuge centrifugalize, not only cause the multiple residual of residue, the fat after centrifugal has also reduced self survival rate.

Summary of the invention

principle: this utility model is the blunt nosed liposuction needle that has various geometry shapes hole on needle tubing [1], injector syringe [2], piston [3], piston union joint [4], negative pressure adjustment hole [5], handle [6], piston packing ring [7], filter screen [8], the connection socket [9] that can be connected with the different pore size trachea according to the connected mode difference, concrete connection is as follows: blunt nosed liposuction needle [1] is connected with injector syringe [2], piston packing ring [7] is arranged on piston [3], filter screen [8] is positioned over piston [3] the inside and piston union joint [4] locking is rear and handle [6], trachea connection socket [9] connects successively, mounted piston [3] is directly inserted injector syringe [2] namely complete installation.It is directly product to be inserted injector syringe, provide negative pressure by negative pressure pump, directly insert human body by liposuction needle and get the fat position, fat enters injector syringe after leaving human body, after being subjected to the interior lipid-water mixt of suction function syringe by filter screen, fat is stayed in syringe, other liquid separate with fat after connecting negative tube by negative pressure pump connection tube interface, and the fat after purification is used for being grafted directly to needs the position, reach save time, laborsaving, safe and effective purpose.

This utility model is to overcome some defectives in existing operation process, provide a kind of can be in operation process quantitatively, implant cleans simple, can realize simultaneously the automatic apparatuses that separate of liquid such as fatty and water, reach when implanting can the former syringe of seamless use as grafting device, can cut down the number of intermediate links, shorten operating time, reduce medical-risk.

This utility model is to be achieved through the following technical solutions its purpose:

What this utility model designed is certain volume fat can be done work by negative pressure pump to extract out and be stored in injector syringe, and the device of certain liq in mixture is fallen in automatic fitration simultaneously.Structurally mainly include liposuction syringe needle, injector syringe, piston, handle union joint, handle, filter screen.The liposuction syringe needle is connected in injector syringe, and piston, handle union joint, handle, filter screen interconnect, the negative tube of vacuum extractor directly with handle on hose connection be connected to form negative pressure channel.After the liquid such as fat and water are extracted into syringe from syringe needle, through filter screen with fluid separation applications such as the fat of jewelry, expensive clothing and other valuables and water, fat is stayed in injector syringe, and the liquid such as water are subjected to suction function to be pulled out injector syringe through filter screen from the handle tail end, keeps the fat of purifying and waits to transplant.

The relative prior art of this utility model has following several respects advantage:

When 1, performing the operation, handle is directly connected in the negative pressure pump negative tube, will firmly press wound when having broken away from former operation, can't guarantee that air enters syringe and causes the situation that fat can not taken out without negative pressure simultaneously;

2, can support the use according to actual needs corresponding injector syringe, make the transplanting data clear;

3, safe design theory can realize operation process without numerous and diverse supporting, once extracts, and cleans simultaneously, purifies and transplant without displacement, avoids the superinfection that is caused by apparatus;

4, standby amount transplant fat and liquid mixture through after inherent filtration to fat without secondary injury, improve transplanting success;

5, simplify operative procedure, save time, reduce simultaneously the painful working doctor amount that reduces of patient;

6, simple in structure, easy to operate, without potential safety hazard, improved each side's benefit.
