Abstract

The invention discloses a self-purified fat quantitative transplanting device and relates to the field of autologous fat transplantation plastic surgery instruments, which is in particular suitable for a little or quantitative fat transplantation during autologous fat transplantation plastic surgery and acts on separation of fat and liquid outside the fat and implantation of purified fat. According to the self-purified fat quantitative transplanting device disclosed by the invention, injector cylinders of different volumes are respectively and uniquely matched, and an injector cylinder piston head replaces an existing injector cylinder piston push rod so that the original changeless push rod is changed to be a channel with a pipe, the channel is provided with a filter screen with the certain aperture, a piston, a negative-pressure regulating hole and a negative-pressure pump connection pipe joint; a product is directly inserted into the injector cylinder, a negative-pressure pump provides negative pressure, a fat extracting needle is directly inserted into a fat-extracted part of a human body, fat enters the injector cylinder after leaving from the human body, the fat is left in the injector cylinder after a fat and water mixture in the injector cylinder passes through the filter screen under negative pressure, other liquids are separated from the fat after passing through a negative-pressure pipe connected with the negative-pressure pump connection pipe joint, and the purified fat is used for being directly transplanted to a required position; and therefore, purposes of saving time and labor and realizing safety and effectiveness are achieved.

Description

From purification Fat quantification grafting device

Technical field

Profit of the present invention relates to autologous fat transplantation plastic operation apparatus field, is specially adapted in the autologous fat transplantation plastic operation a small amount of, quantitatively fat transplantation, act on the fluid separation applications beyond fat and the 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 the similar Surgical Operation in the past: a kind of is to be used 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 the air, after the packing with centrifuge high speed decentraction rotation because process is long and centrifugal destruction, 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 patent is according to co-content injector syringe diameter is not supporting separately, the cylinder piston head is replaced original cylinder piston push rod, change into the tract of pipeline by obstructed push rod originally, be provided with drainage screen, piston, negative pressure adjustment hole, the negative pressure pump connection tube interface of certain pore size in the tract.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, fat is stayed in the syringe after being subjected to the interior lipid-water mixt of suction function syringe by filter screen, other liquid separate with fat after then connecting negative tube by negative pressure pump connection tube interface, and the fat after the purification is used for being grafted directly to needs the position, reach save time, laborsaving, safe and effective purpose.

This patent is to overcome some defectives in the 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 patent is to be achieved through the following technical solutions its purpose:

What this patent designed is certain volume fat can be extracted out and is stored in the injector syringe by the negative pressure pump acting, and the device of certain liq in the mixture is fallen in simultaneously automatic fitration.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 the 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 patent has following several respects advantage:

Handle is directly connected in the negative pressure pump negative tube when 1, performing the operation, and 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 the 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.
