Portable adjustable joint traction device

Abstract

The invention relates to the technical field of medical auxiliary equipment, in particular to a portable adjustable joint traction device which comprises an adjustable retaining ring, an annular traction sliding rail is arranged on the adjustable retaining ring, a first traction mechanism is slidably connected to the annular traction sliding rail, and a second traction mechanism is connected to the upper end of the first traction mechanism. A plurality of pin holes are formed in the annular traction sliding rail, penetrating holes corresponding to the pin holes are formed in the first traction mechanism, and the first traction mechanism is connected to the annular traction sliding rail in a positioning mode through a pin shaft. According to the portable adjustable joint traction device, the surgical palm of a patient penetrates through the adjustable protective ring to be arranged in the inner ring hole of the annular traction sliding rail, the tail end of a kirschner wire on the finger joint of the patient is connected with a rubber belt, the other end of the rubber belt is connected to the first traction mechanism or the second traction mechanism, and the traction effect is achieved; finger joints can be effectively dragged, and better treatment and rehabilitation of a patient are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a portable adjustable joint traction device. Background technique [0002] During the treatment of patients with hand trauma, especially the leftover finger joint problems of patients after the primary surgery for hand trauma, such as the postflexion contracture of the distal interphalangeal joints, proximal interphalangeal joints and metacarpophalangeal joints. When the joint flexion contracture requires a second-stage operation, most of the recovery is not satisfactory after the surgeon loosens the joint during the operation, which is manifested in the unsatisfactory improvement in joint flexion and extension. Contents of the invention [0003] In order to overcome the lack of traction affecting the recovery of the existing knuckle patients after operation, the present invention provides a portable adjustable joint traction device, which puts the palm of t...

Problems solved by technology

[0002] During the treatment of patients with hand trauma, especially the leftover finger joint problems of patients after the first-stage hand trauma surgery, such as the leftover flexion contracture of the distal interphalangeal joints, proximal interphalangeal joints and metacarpophalangeal joints. When the joint flexion contracture requires a second-stage operation, after the surgeon loosens the surgical joint, most of the recovery is not satisfactory, and the joint flexion and extension cannot be improved satisfactorily.
