Negative pressure treatment device used for craniomaxillofacial soft tissue defect disease

Abstract

The invention relates to a negative pressure treatment device used for a craniomaxillofacial soft tissue defect disease. As the negative pressure technology is used for changing inward expansion for treating a craniomaxillofacial soft tissue defect part into outward expansion, treatment risks can be reduced, the treatment effect can be improved, and the negative pressure treatment device brings benefits to patients accordingly. The negative pressure treatment device is characterized by comprising a negative pressure cup; a cup opening of the negative pressure cup is provided with an attachment edge; and the attachment edge is provided with a fitting surface corresponding to an outer enveloping ring of the craniomaxillofacial soft tissue defect part.

Description

technical field [0001] The invention relates to medical equipment for treating craniomaxillofacial soft tissue defects, in particular to a negative pressure treatment device for cranial and maxillofacial soft tissue defects. Expansion can not only reduce the risk of treatment, but also improve the treatment effect, thus benefiting patients. Background technique [0002] Scar contracture after tissue damage, depressed scar, hemifacial atrophy and unexplained soft tissue depression diseases can all lead to soft tissue defects in the face or the whole body, affecting the shape, especially facial lesions, leading to the destruction of the patient's appearance and serious psychological disorders . Treatment methods for such diseases include vascularized flap transplantation, expander flap transfer repair, and autologous fat injection transplantation. Among them, autologous fat injection transplantation is to take out fat from other parts of the body only by liposuction, wash an...

AI Technical Summary

Problems solved by technology

The main reasons are as follows: 1. Scars and diseased tissues are hard in texture, poor in ductility, and difficult to fill; the amount of injection per operation is limited

2. Tissue extensibility is poor. After fat particles are implanted, the pressure is high, and the increase in pressure will promote the absorption of fat cells, resulting in a decrease in surgical effect or hours

3. Poor blood supply of diseased soft tissue, poor fat tissue implantation, difficulty in establishing blood supply around fat cells, leading to fat cell apoptosis and absorption

However, soft tissue expansion requires surgery to implant the expansion capsule into the tissue, which increases the trauma of the patient.

And for tissue scar contracture, hemifacial atrophy tissue is implanted with soft tissue expander, which can easily lead to complications such as skin infection and perforation, high surgical risk and poor treatment effect
