Dactylion separating and spreading device

Abstract

The invention discloses a dactylion separating and spreading device. The device comprises a first U-shaped frame (13), a second U-shaped frame (14), wherein the first U-shaped frame (13) and the second U-shaped frame (14) are buckled together mutually to form an enclosed ring capable of regulating width; the opening ends of a first finger bone U-shaped frame (21) and a second finger bone U-shapedframe (27) are provided with hinges (24); the hinges are provided with hinge holes (25); and a locking screw (11) penetrates through guide grooves (19) on a guide positioning sleeve (12), the first U-shaped frame (13) and the second U-shaped frame (14). According to the invention, the defect that the additional pain caused by the cutting of the conglutination part by the existing operation methodis overcome; and by elastically regulating the spreading force of a bolt, the finger web can be separated apart naturally, the finger web can also be prolonged naturally, and natural physiological skin can be formed.

Description

technical field [0001] The invention relates to a medical device, more specifically, it is a finger separation spreader using tension-stress constant force. 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. After the adhesion is formed, the existing method is to cut the adhesion part through plastic surgery and give the patient cause additional pain. [0003] In order to improve this situation, the applicant of this patent applied for the patent of the joint finger spreader on September 3, 2010, the patent number is 201020516223.0, but this kind of joint...

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. After the adhesion is formed, the existing method is to cut the adhesion part through plastic surgery and give the patient cause extra pain

[0003] In order to improve this situation, the applicant of this patent applied for the patent of the joint finger spreader on September 3, 2010, the patent number is 201020516223.0, but this kind of joint finger spreader is inconvenient for doctors to install, especially splints, clamps, etc. It takes a long time for the doctor to install the seat, bolt positioning clip, double-needle positioning clip, etc., and requires a high level of installation technology for the doctor, and it is easy to loosen during use.

In addition, the overall stability of the frame is not enough, which is easy to cause injury to the patient. In actual use, due to the patient's misoperation, it is easy to cause the deformation of the frame, and the medical effect cannot be guaranteed.
