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 becaus

Example Embodiment

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

[0016] This embodiment is directed to a tissue expander with an external valve, which is characterized in that it includes an injection pot A, a water pipe B, an expansion capsule C, and a mold D. The installation method is:

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

[0018] The size and shape of the die D and the expansion capsule C are exactly the same, and the material is paper or plastic, and is placed in a sterile package.

[0019] The injection pot A is composed of the front wall A-1. Because the injection pot is placed outside, it is filled with water directly, without the need for built-in iron plates. The injection pot cavity A-2 and the rear wall A-3 are composed of the front wall A-1. Thickening reduces the possibility of water seepage after needle sticks.

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] At present, the widely used controllable dilator is designed and applied according to the built-in method of the injection pot. Therefore, it is necessary to place an iron sheet in the pot to prevent the needle from penetrating when injecting water. The silicone sheet is weak and prone to water seepage after multiple needle sticks. Circumstances, and the biggest problem with the built-in is the pain of needle stick during injection. In current clinical operations, most of the injection pots have been placed externally. The advantage is that it reduces the pain of needle sticks during injection, simplifies the operation, saves time, and is clinically proven that this does not increase the risk of infection. [0003] In the first phase of application of the tissue expander, a expander of appropriate size and shape nee...
