Description
The technical field is as follows:
the invention relates to the technical field of medical instruments, in particular to an external skin stretching device.
Background art:
the principle is that the skin edges on two sides of the wound are pulled towards the center by using an external stretching device by utilizing the looseness and the extensibility of the skin, so that the wound is gradually reduced, and finally the wound surface is sutured and eliminated. The currently adopted distractor is an independent pair of teeth and buckles which are matched for use, and the teeth and the buckles are respectively sewed and fixed on the skin at two sides perpendicular to the long axis of the wound. 3 to 4 distractors are selected according to the size of the wound or the wound surface. However, such a distractor has the obvious disadvantage that the force application points are limited to a few points in the longitudinal direction of the wound edge, and the following disadvantages are generated during the use process: 1. the stretching efficiency is low, and the treatment time is long; 2. the excessive tension of part of the parts is easy to cause necrosis and tearing of stress points, thus increasing the pain of patients; 3. because the skin at the wound edge often has the adverse conditions of inflammation, edema, scar hyperplasia and the like, the difference of the wound traction distance is large, the ductility of the part with the large traction distance is poor, the texture of the skin is thinned after the skin is reluctantly stretched, and the wound healing quality is influenced; 4. more and healthier skin on both sides of the wound is not effectively mobilized. According to the patent with the patent number ZL201420763740.6, two fixing plates are arranged on two sides of a wound of a human body, a plurality of fixing pieces are correspondingly arranged on opposite sides of the two fixing plates, the fixing pieces on the two sides correspond in position and are equal in number and face the wound, and the fixing pieces on the two sides are detachably connected through connecting strips; the fixing plate and the fixing plate are both provided with suture holes for fixing on the skin. Effectively mobilize the skin at the wound margin and the normal skin at the outer side of the wound margin in a larger range, so that the stretching effect is good, the healing quality is higher, the probability of tearing the skin is reduced, and the pain of a patient is relieved. However, the fixing plate and the fixing plate are symmetrically arranged on two sides of the wound, the tension force is symmetrical, the device is suitable for the wound with a regular shape, the reasonable arrangement of the fixing plate can not be carried out according to the shape of the wound for the wound with a complicated wound surface with an irregular shape of skin wound, and the direction of the tension force can not be adjusted in the wound recovery process, so that the tension effect is general, and the wound healing speed is influenced.
