An electric revision instrument for hip revision surgery

Abstract

The invention discloses an electric revision instrument for hip joint revision surgery, which belongs to the field of hip joint surgery and includes a main box, a sewage pipe is installed on the lower side of the main box, and the bottom end of the sewage pipe is disassembled through a threaded pipe A collection bottle is installed, a main pipe is installed on one side of the main box, and a telescopic tube is slidably installed at one end of the main pipe away from the main box, and a sub-pipe is installed at the end of the telescopic tube away from the main pipe, and a The first helical blade rod, the second helical blade rod is rotatably installed in the sewage pipe, and the main shaft is rotatably installed in the main box. The electric revision instrument of this scheme can have the functions of cutting tools and cleaning dirt at the same time through various structural settings, and can quickly switch between the two functions, making the operation more smooth and reducing the time-consuming operation. Quick and smooth cleaning and collection of debris and other dirt, avoiding pipeline blockage caused by collection.

Description

technical field [0001] The invention relates to the technical field of hip joint surgery, in particular to an electric revision instrument for hip joint revision surgery. Background technique [0002] Hip joint replacement, also known as artificial hip replacement, is to fix the artificial prosthesis, including the femoral part and the acetabular part, on the normal bone with bone cement and screws to replace the diseased joint and reconstruct the normal state of the patient's hip joint. It is a relatively mature and reliable treatment method. Artificial joints began in the 1940s abroad, and gradually developed in my country after the 1960s. In the early days, only the artificial femoral head was replaced, commonly known as half hip replacement, and later developed into total hip replacement. Osteoarthritis, femoral head necrosis, femoral neck fracture, rheumatoid arthritis, traumatic arthritis, benign and malignant bone tumors, ankylosing spondylitis, etc., as long as the...

AI Technical Summary

Problems solved by technology

[0004] The electric overhauling instrument in the prior art has the following disadvantages: when the electric overhauling instrument is in use, a tool with power is required, and at the same time, the function of cleaning blood, bone debris, and even tissue debris and other dirt is required. These functions cannot be realized with the same part of the structure, and cannot be switched quickly and smoothly, resulting in a long time-consuming operation. In addition, when removing blood, bone debris and tissue debris, the use of negative pressure may easily cause pipeline blockage and affect normal use of instruments, so we re-propose a powered revision instrument for hip revision surgery
