Integrated thread passing device beneficial to arthroscopic ligament insertion fracture surgery

Abstract

The invention discloses an integrated thread passing device beneficial to arthroscopic ligament insertion fracture surgery. The integrated thread passing device includes an outer needle body and an inner core; the outer needle body is hollow, the inner core is cooperatively arranged inside the outer needle body, the front end of the outer needle body is a tip, a thread embedding hole is formed inthe tip face of the outer needle body, a threading hole is formed in the side wall of the middle of the outer needle body, and a positioning step is arranged on the inner wall of the rear portion of the outer needle body; the front end of the inner core is a tip, a filling column head is arranged on the tip face of the inner core, the tip face of the inner core cooperates with the inner wall faceof the tip of the outer needle body, the front end face of the filling column head is flush with the tip face of the outer needle body, the filling column head fills and cooperates with the thread embedding hole, the positioning step is arranged on the rear portion of the inner core, and a positioning step of the inner core positionally cooperates with the positioning step of the outer needle body. By adopting the integrated thread passing device, the surgery time of the arthroscopic ligament insertion fracture surgery is greatly saved, a ligament insertion fracture block can be fixed all thetime during the surgery, the ligament insertion fracture block is prevented from moving, and thus the integrated thread passing device beneficial to the arthroscopic ligament insertion fracture surgery has excellent popularization significance.

Description

technical field [0001] The invention belongs to the technical field of medical operation equipment, and relates to an integrated wire-passing device that is simple in structure and convenient to use, and is beneficial to arthroscopic ligament insertion fracture surgery. Background technique [0002] The cruciate ligament is an important stable structure in the knee joint. It is hinged between the intercondylar fossa of the femur and the intercondylar eminence of the tibia to prevent the tibia from shifting forward and backward along the femur. Fractures of the cruciate ligament insertion point are very common in clinical practice. Arthroscopic reduction and fixation of cruciate ligament fractures has been used clinically as a gold standard operation. At present, the most commonly used method for bone reduction and fixation under arthroscopy is to reset the bone first and then temporarily fix it with Kirschner wires. Steel wires, threads, anchors and screws can be used for fi...

AI Technical Summary

Problems solved by technology

However, the problem with this method is that the Kirschner wires need to be taken out separately while using Kirschner for temporary fixation of the bone block. Prolonging the operation time will affect the quality of the operation. Therefore, it is of great significance and clinical practical value to develop an integrated wire-passing device that is beneficial to arthroscopic ligament insertion fracture surgery.
