Incision traction device for orthopedic surgery

Abstract

The invention provides an incision traction device for orthopedic surgery. The incision traction device comprises a fixing assembly, a telescopic column and a traction device body; the traction device comprises a box body, a driving assembly, two traction arms and traction blocks at the lower ends of the traction arms, and length adjusting assemblies are arranged on the traction arms; the driving assembly comprises a horizontal rotating disc, the traction arms are fixedly connected with the horizontal rotating disc, the other ends of the traction arms extend out of the front side wall of the box body, a vertical rotating shaft penetrates through a driven bevel gear, a horizontal rotating shaft is arranged on the rear side wall of the box body, a driving bevel gear and gears penetrate through the horizontal rotating shaft, the gears are meshed with each other, A horizontal rotating shaft extends out of the rear side wall of the box body and is fixedly connected with a hand crank; and the traction blocks are rotationally connected with the traction arms through vertical hinge shafts, and rotary positioning assemblies are arranged between the traction blocks and the hinge shafts. The device is connected with an operating bed, the structure is stable, time and labor are saved, the adjusting speed is gentle, the situation that a doctor pulls off force to make an incision slide is avoid, the traction blocks are more attached to the inner wall of the incision, the medical burden is relieved, and the operation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an incision traction device for orthopedic surgery. Background technique [0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries has undergone significant changes. For example, bone and joint tuberculosis, osteomyelitis, polio and other diseases have decreased significantly, and trauma caused by traffic accidents has increased significantly. The changes in the spectrum of orthopedic injuries undoubtedly have higher requirements for orthopedic surgical instruments. [0003] Orthopedic surgery usually uses a scalpel to cut open the injured part of the patient and operate dir...

AI Technical Summary

Problems solved by technology

However, the incision in orthopedic surgery is generally larger and deeper. If the doctor or assistant simply uses tweezers or other medical tools to hold and open the incision, the doctor or assistant is likely to lose strength during the long operation and make the incision slide, which is harmful to the operation. The process has a great impact, increasing the workload of medical staff, and the medical staff are crowded together, which is inconvenient for doctors to operate and reduces the efficiency of surgery

[0004] At present, there are many incision traction devices that do not use manual traction, but there are still some problems. For example, the existing traction devices adjust their relative positions with the fixed arms through the movement of the moving arm. Such an operation causes the skin on both sides of the opening The muscle and the muscle cannot be retracted at the same time with the same strength. Doctors often need to adjust the moving arm while moving the entire retractor to the side of the fixed arm, which is more laborious; The tearing and injury of the opening affect the entire operation process; moreover, the angle between the pulling block and the pulling arm is fixed, and when the pulling angle changes, the pulling block cannot fit well with the inner wall of the incision, resulting in weak force on the inner wall of the incision. Even, it is easy to cause the incision to tear, causing secondary injury to the patient
