Embodiment Construction

[0020] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] see Figure 1-Figure 2 , a negative pressure skin external dilator of the present invention is composed of an air cushion type negative pressure cover, a right angle conversion tube, a connecting tube, and a negative pressure generating device. One end of the right angle conversion tube is connected to the top of the air cushion type negative pressure cover , the other end of the right-angle conversion pipe is connected to the connecting pipe, and the connecting pipe is connected to the negative pressure generating device.

[0022] The air cushion type negative pressure cover is composed of a cover body, an air bag, and an air valve. The air bag is connected to the edge of the bottom of the cover body, and the air valve is fixed on the cover body, and the air valve communicates with the air bag. The cover body is in the shape o...

Abstract

The invention relates to a skin expander, in particular to a negative pressure type skin external expander. The negative pressure type skin external expander comprises an air cushion type negative pressure cover, a right-angle conversion pipe, a connecting pipe and a negative pressure generation device, wherein one end of the right-angle conversion pipe is connected with the top of the air cushion type negative pressure cover, the other end of the right-angle conversion pipe is connected with the connecting pipe, and the connecting pipe is connected with the negative pressure generation device. The negative pressure type skin external expander can be sufficiently attached to different curved-surface portions of the human body, can also be attached to the portions with much hair, can form a sealed partial space, is simple in operation, is convenient to adjust, can eliminate the fear of a patient, resolves the problem that it is difficult for the patient to see a doctor, and improves work efficiency.

Description

technical field [0001] The invention relates to a skin expander, in particular to a negative pressure external skin expander. Background technique [0002] Tissue expansion is a surgical method that uses the expansion of tissue expanders to obtain extra skin and soft tissue for skin defect repair and organ reconstruction. Tissue expansion is a revolutionary achievement in the field of plastic surgery in the past 20 years. It is the most widely used in the treatment of scars and body surface tumors. It solves many difficult clinical problems and replaces some skin grafts and flaps. . The application of skin expansion not only improves the quality of plastic surgery, but also reduces the surgical injury. [0003] Expansion can increase the area of ​​skin, and there are three sources of extra skin and soft tissue: ① tissue growth induced by expansion stimulation, and skin growth exists both during the expansion process and after the expansion flap is transferred. The expansi...
