Problems solved by technology

Before making the incision in the first-stage operation, it is necessary to mark the area to be stripped on the body surface according to the size and shape of the dilator. Generally, the traditional method is to use the dilator directly on the skin for marking, but because the dilator is an implant material, it is easy to occur. Complications of infection, and this step directly contacts the dilator with the skin. Although the skin has been disinfected, there may still be residual bacteria on the dilator, aggravating the risk of infection

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] This embodiment is aimed at a tissue expander with an external valve, which is characterized in that it includes an injection pot A, a water guide tube B, an expansion bag C, and a die piece D. The installation method is as follows:

[0017] One end of the aqueduct B is connected to the injection pot A and the other end is connected to the expansion bag C.

[0018] The mold piece D is exactly the same size and shape as the expansion bag C, and its material is paper or plastic sheet, and it is placed in a sterilized package.

[0019] The injection pot A is composed of the front wall A-1, because the injection pot is placed outside, and the water is injected under direct vision, there is no need for a built-in iron sheet in the pot, the injection pot cavity A-2, the rear wall A-3, and the front wall A-1 Thickened to reduce the possibility...

Abstract

The invention relates to the field of tissue expansion, in particular to a tissue expander with an external valve. The expander comprises an injection pot (A), a water guide tube (B), an expansion bag (C) and a matrix (D). One end of the water guide pipe (B) is connected with the injection pot (A), the other end of the water guide pipe is connected with the expansion bag (C), and the matrix (D) completely identical with the expansion bag (C) in size is arranged in a disinfected package. The tissue expander is simple in operation and saves operation time. Water injection is conducted under direct sight, a built-in iron piece is not required, the silica gel at the injection portion can be thickened, water seepage is reduced after needle punching, the disinfected matrix replaces the expander to conduct skin marking, and the postoperative infection risks are reduced.

Description

technical field [0001] The invention relates to the field of tissue expansion, in particular to a tissue expander with an external valve. Background technique [0002] The currently widely used controllable dilator is designed and applied according to the built-in method of the injection pot, so it is necessary to place an iron sheet in the pot to prevent the needle from being pierced when injecting water. The silicone sheet is weak, and it is prone to water seepage after multiple needle sticks. situation, and the biggest built-in problem is the pain of needle sticking during injection. At present, during clinical operations, most of the injection pots have been placed externally. The advantages are to reduce the pain of needle sticks during injection, simplify the operation, save time for the operation, and a large number of clinical trials have confirmed that this does not increase the risk of infection. [0003] In the first-stage application of the tissue expander, it i...
