Problems solved by technology

In the existing steel wire cerclage, doctors use cerclage pliers to manually bind and fix the steel wires. This method does not adjust the fineness of the tension of the steel wires enough. During the postoperative recovery stage, if an external impact is received, the fracture position will easily appear. secondary dislocation

Abstract

The invention discloses a minimally invasive cerclage device which comprises a cannula. A first thread is arranged on the inner wall of the cannula, an adjusting column is nested in the cannula, a second thread which meshes with the first thread is arranged on the outer surface of the adjusting column, two first through holes are symmetrically formed in the side surfaces of the cannula, and two ends of a cerclage thread are inserted into the cannula via the two first through holes; a plurality of protrusions are uniformly arranged on the top of the second thread, a first groove is formed in the bottom of the first thread, a first rubber layer is arranged in the first groove, the protrusions are in contact with the first rubber layer, hang rings are fixedly connected with two ends of the cerclage thread, and each hang ring is connected with an optional protrusion in a hung manner after penetrating the corresponding through hole. The minimally invasive cerclage device has the advantagesthat the shortcomings in the prior art can be overcome by the aid of the minimally invasive cerclage device, and the cerclage tension degree control precision can be improved for fracture sites.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a minimally invasive cerclage device. Background technique [0002] When carrying out fracture site fixation to fracture patient, steel wire cerclage is a kind of commonly used means. In the existing steel wire cerclage, doctors use cerclage pliers to manually bind and fix the steel wires. This method does not adjust the fineness of the tension of the steel wires enough. During the postoperative recovery stage, if an external impact is received, the fracture position will easily appear. A dislocation situation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a minimally invasive cerclage device, which can solve the deficiencies of the prior art and improve the control precision of the tension of the cerclage at the fracture site. [0004] In order to solve the above technical problems, the technical solutions adopted by the ...
