Small bone saw for joint surgery

Abstract

The invention discloses a small bone saw for joint surgery and belongs to the field of joint surgery devices. The small bone saw for joint surgery comprises a handheld arm, a power box is fixedly connected to the handheld arm, a long arm rod is connected to the power box in an inserted mode, an electric push rod matched with the long arm rod is fixedly connected to an interior of the power box, one end, away from the power box, of the long arm rod is fixedly connected with a movable joint, the movable joint is connected with a movable rod, one end, away from the movable joint, of the movable rod is fixedly connected with a working end table, the working end table comprises a shell, a mounting hole is formed in the shell, a hollow rotating shaft is rotationally connected into the mounting hole, a circular sawtooth blade is fixedly connected to the hollow rotating shaft, an induced draft fan is arranged in a rotating column, and a corrugated air guide pipe is connected between the induced draft fan and the hollow rotating shaft. Grinding and cutting can be carried out according to needs in an operation process. The small bone saw for joint surgery can be easily adapted to different use environments. By locking and fixing the movable rod and the corrugated air guide pipe, stability of a working end during working is guaranteed.

Description

technical field [0001] The invention relates to the field of joint surgery devices, in particular to a small bone saw for joint 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. [0003] Most orthopedic operations require cutting and other operations on all parts of the bone. However, the general driving device of the existing bone saw is not much different from the traditional saw on the outside; the wound surface is large during ...

AI Technical Summary

Problems solved by technology

[0003] Most orthopedic operations require cutting and other operations on all parts of the bone. However, the general driving device of the existing bone saw is not much different from the traditional saw on the outside; the wound surface is large during cutting, and the bone foam after cutting If it is not cleaned properly, it will cause serious sequelae

[0004] Moreover, most of the current bone saws for joint surgery are manually operated, and the efficiency of the former is low. Due to the technical level of the operator, the bone saws will cause side injuries, affect the healing rate and prolong the postoperative recovery period; Due to the large space limitation, the bone saw is easy to get stuck due to insufficient space in multi-person surgery, which affects the efficiency of the operation and the recovery of the wound, which increases the pain of the patient and increases the cost of treatment.
