Mini track for opening hand skin of children with syndactylia

Abstract

The invention relates to a mini track for opening hand skin of children with syndactylia. The mini track comprises two groups of fixing pieces, a first fixing plate, a second fixing plate, a first sliding piece, a second sliding piece and a sliding limiting device, wherein the fixing pieces are fixedly connected with the first fixing plate and the second fixing plate respectively, the first fixingplate is connected with the first sliding piece, the second fixing plate is connected with the second sliding piece, and the first sliding piece and the second sliding piece are connected through a sliding rail and an embedding piece; and one end of the sliding limiting device is fixed to the first sliding piece, and the other end of the sliding limiting device is fixed to the second sliding piece for fixing and limiting after the first sliding piece and the second sliding piece move. According to the mini track, the opening angle can be adjusted according to a recovery plan of a patient through scales of the sliding rail, the correction effect is better, operation is convenient, self-operation can be achieved, and the operation burden of doctors is greatly reduced. Through the design ofan elastic material of the fixing plates, the joint part of the middle of the finger of the patient can also be bent to a certain extent, and comfort is improved.

Description

technical field [0001] The invention relates to the field of correction of syndactyly deformity of children, in particular to a hand skin stretching mini track for syndactyly deformity of children. Background technique [0002] Finger webs are the joints between the fingers or toes of the human body. Children’s fingers or toes are born with syndactyly, or adults have severe burns on the finger webs or after finger web skin grafting, the finger webs are prone to adhesions, which will affect the patient’s fingers or toes. The range of motion and the function of fingers or toes are also very unsightly, causing very bad effects on the patient's physiology and psychology. Additional pain, more serious, because the skin is not enough, the skin tension is high after pulling and suturing, and it is easy to necrosis. [0003] At present, the prior art also has corresponding finger skin stretchers, such as the finger skin stretcher disclosed in CN201831912U and the children finger sk...

AI Technical Summary

Problems solved by technology

[0002] Finger webs are the joints between the fingers or toes of the human body. Children’s fingers or toes are born with syndactyly, or adults have severe burns on the finger webs or after finger web skin grafting, the finger webs are prone to adhesions, which will affect the patient’s fingers or toes. The range of motion and the function of fingers or toes are also very unsightly, causing very bad effects on the patient's physiology and psychology. Additional pain, more serious, due to insufficient skin, high skin tension after pulling sutures, easy to necrosis

[0003] At present, the prior art also has corresponding finger skin stretchers, such as the finger skin stretcher disclosed in CN201831912U and the children finger skin stretcher disclosed in CN203107189U. , but there is a problem that the angle between the two retracted fingers needs to be constantly adjusted, which is not easy to realize natural stretching, while the combined finger separation spreader disclosed in CN102302380B has a relatively complicated structural design, which means Installation, use, and removal are more complicated, and the convenience of use is poor, so it is not suitable for promotion and application

In addition, there is a skin spreader disclosed by CN209847261U. The angle of expansion is determined by adjusting the installation position of the elastic element and the telescopic spring of the elastic element. Elastic elements, and there may be the problem that the elastic elements need to be disassembled and replaced during the recovery process of the patient, the operation is complicated and not convenient, the utilization rate of parts is low, and the manufacturing cost is wasted
