One-way locking and pressurizing knotting-loop-free steel plate fixing structure

Abstract

The invention discloses a one-way locking and pressurizing knotting-loop-free steel plate fixing structure. The fixing structure comprises a fracture dislocation opposite side loop steel plate, a surgical incision side loop steel plate, a loop wire and a tail cap, the main body of the loop wire penetrates through a third through hole in the surgical incision side loop steel plate towards the opposite side, then sequentially and continuously penetrates through a first through hole and a second through hole in the fracture dislocation opposite side loop steel plate towards the opposite side, penetrates through a fourth through hole in the surgical incision side loop steel plate towards the surgical incision side, and finally penetrates through a fifth through hole in the tail cap. A fifth clamping tooth is meshed with a third clamping tooth, a first clamping tooth, a second clamping tooth and a fourth clamping tooth in sequence to form a one-way locking structure, four times of progressive pressurization are performed; the tail cap is arranged at the tail end of a loop wire body, so that partial loss of the pressurizing effect in the knotting process is avoided, the fixing stabilityand firmness are improved, the tail cap is used for locking and fixing the tail end of the loop wire body in an occlusion mode, knotting is not needed, and local knotting foreign matter reaction and discomfort caused by too many knots after a patient operation are reduced.

Description

technical field [0001] The invention relates to daily necessities for human beings, in particular to a medical device, in particular to a one-way locking, pressurized, knot-free loop steel plate fixing structure. Background technique [0002] Loop plates are most commonly used in the treatment of fracture-dislocations in trauma orthopedics, most commonly in inferior tibiofibular joint dislocations and coracoclavicular ligament injuries. At present, clinically, most of the bones to be reset are clamped by two Endo button steel plates (button steel plates), and then the two Endo button steel plates are used to connect the two Endo button steel plates. On the opposite side of the fracture and dislocation, another steel plate is placed on the side of the surgical incision. The two steel plates are connected by a loop, pressurized and knotted to complete the fixation. The loop steel plate in the prior art is fixed by pressure at the tail end of the loop wire. In order to maintai...

Problems solved by technology

[0003] The object of the present invention is to provide a one-way locking, pressurizing, knot-free loop steel plate fixing structure. The one-way locking, pressurizing, knot-free loop steel plate solves the problem that the tail end of the loop line in the prior art often needs to be repeatedly tied. Knot at least 5 times, the operation is cumbersome, it is easy to cause local knot reaction, and in the process of knotting operation, it often leads to technical problems that part of the pressurization effect is lost
