Problems solved by technology

The shortcoming of existing soft tissue dilator is: one is to make the expansion bag fully expand as far as possible, obtain suturing skin area as early as possible, also must prevent the pressure of expansion bag from causing skin soft tissue necrosis at the same time, so the water injection process must be performed by medical personnel. For the operation, the patient must go to the hospital to inject water every two or three days, which brings inconvenience and even pain to the patient; secondly, the pressure fluctuation in the expansion sac is large, and the expansion treatment course is too long (about 45-60 days), which prolongs the patient's life. pain
[0003] In order to make patients safer and more convenient, and to reduce pressure fluctuations in the pores, some related improvements have also been disclosed in Chinese and foreign patents. For example, 97240319.1 in Chinese patent describes a continuous dripping skin The soft tissue dilator adopts an infusion bottle for intravenous infusion, a drip pot, a drip tube, and a drip control switch clip to form an extracorporeal liquid pressure device, and a screw is installed between the water injection valve of the expansion bag, the catheter, and the drip tube. In order to achieve a certain degree of con

Example Embodiment

[0033] Example 1

[0034] Such as figure 1 Shown: a self-service or automatic skin and soft tissue expansion device of the present invention consists of a dilatation balloon buried in the subcutaneous 1, connecting tubes 2-1 and 2-2 with a length extending from the subcutaneous to above the body surface. The elastic airbags 3 of the air inlet 3-1 and the air outlet 3-2 are connected in sequence. The airbag 3 is connected to the air inlet 3-1 with a one-way suction valve 4, and the air outlet 3-2 is connected with a one-way Outlet valve 5;

[0035] The connecting pipe is divided into upper and lower sections. The lower section 2-1 of the connecting pipe is the lead-out section of the expansion capsule 1, and the upper section 2-2 is the pipe section outside the body surface. There is a sealing movable joint between the two sections, and the sealing is movable The connector includes the lower part 2-1 port and the peripheral threaded pipe clamp 6, the upper part 2-2 port inner shea...

[0038] Example 2

[0039] Such as figure 2 Shown: the embodiment of the gas-liquid composite pressure charging device of the present invention, that is, a liquid pressure bottle 10 is connected in series on the connecting pipe between the pressure limiting valve 8 and the upper port 2-2, and the liquid pressure bottle 10 is connected in series on the connecting pipe between the pressure limiting valve 8 and the upper port 2-2. Two catheters are inserted into the air-tight stopper 11 of the pressurized bottle 10, of which the long catheter 12-1 deep into the bottom of the bottle communicates with the outlet tube 2-1 from the expansion balloon 1, and the outlet tube 2 of the expansion balloon 1 The lower port of 1 is connected in series with an on-off valve 13; the other short tube 12-2, which is shallow and close to the stopper, communicates with the port of the connecting pipe from the pressure limiting valve 8 and the inflatable bag 1;

Abstract

The self-supporting or automatic skin soft tissue dilator consists of dilating bag under the skin, connecting pipe and inflator connected successively. It features the connecting pipe extending from under skin to body surface and with section outside the body connected to an adjustable pressure-limiting valve via a T-union. The inflator is one elastic bag with air inlet connected to a non-return sucking valve and air outlet connected to a non-return outlet valve. The connecting pipe includes two sections connected via a sealing union. The pressure-limiting valve is also connected to a pressure gauge with red warning label beyond 60-80 mmHg area. The present invention is used to dilated under skin and has less pressure fluctuation.

Description

【Technical field】 [0001] The invention relates to a plastic surgery instrument, in particular to a skin and soft tissue plastic surgery instrument. 【Background technique】 [0002] In plastic surgery, it is often necessary to suture the surgical opening where the skin and soft tissue have been removed in a large area, or where the scalp is hard and difficult to suture. It is very troublesome to use heterodermal transplantation or even self-skin grafting. Currently, the most popular is A skin and soft tissue expander is embedded subcutaneously near the skin and soft tissue at the sutured site, and the surface area of ​​the skin and soft tissue is gradually expanded by using the skin and soft tissue expander, so that it can gradually reach the level of self-suture, thereby greatly simplifying the operation and improving the quality of life. The safety and quality of the operation; currently there are two main structures of soft tissue expanders used clinically: one is to embed ...
