Artificial hip joint replacing-retracting-exposing positioner

Abstract

The invention relates to an artificial hip joint replacing-retracting-exposing positioner which belongs to medical appliances. The top side part and one side part of the n-shaped frame are respectively sheathed with a first elastic clamp seat assembly and a second elastic clamp seat assembly; a draw hook connecting rod and a sharp hook connecting rod are respectively inserted on the first elastic clamp seat assembly and the second elastic clamp seat assembly; a pelvis obturator foramen long-handle draw hook and an acetabula front-edge exposing-positioning sharp hook sleeve are respectively connected to the draw hook connecting rod and the sharp hook connecting rod through an adjustment through hole A and an adjustment through hole B; the ends on both sides of the n-shaped frame are respectively provided with a shallow-layer tissue retracting-positioning hook and a positioning column; a parenchyma retracting hook is sheathed on the positioning column through an adjustment through hole C; a shallow-layer tissue retracting-positioning brace rod is fixed on a shallow-layer tissue retracting-positioning hook; and an acetabula upper edge retracting-positioning pin is arranged on the outer side of the open end of the n-shaped frame. The invention has the advantages of simple structure, convenient use, reliable operation, accurate and stable operative field range, and is beneficial to ensuring the operation quality and enhancing the operation efficiency.

Description

technical field

[0001] The invention belongs to medical equipment, and mainly relates to an orthopedic artificial hip joint replacement operation equipment. Background technique

[0002] At present, during artificial hip replacement surgery, after incision of the skin and soft tissue layers, four auxiliary medical staff are required to hold the soft tissue retraction hook plate, the pelvic obturator hook plate and the acetabular anterior edge exposure hook plate respectively. Use manpower to pull the soft tissue apart, exposing enough of the hip joint to allow the surgical operation to be completed. However, since the determination of the range of the operative field is manually controlled by four surgical assistants holding four hook plates, and the operation time is long, the range of the operative field often changes due to changes in the traction force. Unstable, even the phenomenon that the hook plate slips from the soft layer tissue and other parts, not only many surg...
