Skin distractor capable of simultaneously using negative pressure suction

Abstract

The invention discloses a skin distractor capable of simultaneously using negative pressure suction. The skin distractor comprises: a porous hose arranged along a first direction; a bottom dressing, wherein at least a part of the bottom dressing is in contact with the porous hose; a distraction line arranged in a second direction intersecting with the first direction, wherein one end of the distraction line is connected with a traction plate, and the traction plate is connected with the skin; and a winding mechanism comprising a winding shaft outer cylinder arranged above the bottom dressing, a winding shaft with the lower end arranged in the winding shaft outer cylinder, and a knob matched with the upper end of the winding shaft, wherein a wire outlet hole is formed in the winding shaft outer cylinder, the other end of the distraction line is connected with the winding shaft through the wire outlet hole, the other end of the distraction line is connected with the knob, and one end of the distraction line moves towards the winding shaft or is allowed to move away from the winding shaft by rotating the winding shaft. According to the invention, traction and negative pressure suction of skin can be achieved at the same time, and infection can be avoided through the negative pressure suction technology while the skin traction operation is carried out.

Description

Technical field [0001] The present invention relates to the technical field of VSD suction, particularly to a suction may be used simultaneously distractor skin. Background technique [0002] VSD dressing means comprising internal draft tube to cover or fill in skin, wound and soft tissue defects, and then closed for a biological semi-permeable membrane, making it a closed space, and finally turn on the drainage tube negative pressure source, via the negative control to promote wound healing, a method of preventing infection being treated. [0003] On the other hand skin and soft tissue defects surgery is a common clinical problem, there are many, tumors, scars, trauma, inflammation, surgery and skin disease itself and other reasons. In skin wound edge high tension, the case can not be directly sutured to the usual manner using a flap or skin graft to repair. A recently developed technology utilizes skin stretch and loosen skin extensibility, using the distractor skin edge toward...

AI Technical Summary

Problems solved by technology

[0004] VSD can prevent infection very well, but during its use, the skin will be in a retracted state and adhere to deep tissues, which prevents direct wound suturing in the later stage

On the other hand, in the prior art, the skin stretcher cannot perform VSD suction during use, because skin stretching is a slow process, and in this process, the wound surface can only be bandaged with traditional dressings, which is easy Serious consequences caused by infection of wounds and even deep tissues (muscles, tendons, bones, joints)
