Abstract

The invention discloses an electric revision instrument for hip joint revision surgery, and belongs to the field of hip joint surgery. The electric revision instrument comprises a main box; a blow-offpipe is mounted on the lower side of the main box; a collecting bottle is detachably mounted at the bottom end of the blow-off pipe through a threaded pipe; a main pipe is mounted on one side of themain box; a telescopic pipe is slidably mounted at the end, away from the main box, of the main pipe; a sub-pipe is mounted at the end, away from the main pipe, of the telescopic pipe; a first spiralblade rod is rotatably mounted in the main pipe; a second spiral blade rod is rotatably mounted in the blow-off pipe; and a main shaft is rotatably mounted in the main box. According to the electric revision instrument, through the arrangement of all the structures, the functions of cutter crushing and dirt cleaning can be achieved at the same time, the two functions can be rapidly switched, operation is smoother, operation time consumption is reduced, and meanwhile, dirt such as bloody water, bone residues and tissue debris and the like can be rapidly and smoothly cleaned and collected, and pipeline blockage during collection is avoided.

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...
