Abstract

The invention relates to a surgical instrument in the medical field and mainly relates to anultrasonic acetabular reamers and file thereof suitable for minimally invasive/total hip replacement. The ultrasonic acetabular reamers comprises a control device, a handle and a file, wherein the handle comprises a piezoelectric ultrasonic generator and a transmission mechanism; the piezoelectric ultrasonic generator comprises two groups of piezoelectric elements, and the two groups of piezoelectric elements respectively control the transverse and longitudinal ultrasonic vibration, the piezoelectric ultrasonic generator is connected with the transmission mechanism, the control device is connected with the ultrasonic generator, and the transmission mechanism is connected with the file through the conversion adapter. Compared with the prior art,, the ultrasonic acetabular reamers can quickly and safely grind the rigid tissue with smooth grinding surface and small amount of bleeding, while preventing wear through the acetabulum, and the two kinds of designed cutter heads can be used with the ultrasonic acetabular reamers, the acetabular reamers handle and the file are angled for minimally invasive/total hip replacement. The ultrasonic acetabular reamer reduces the damage of the operation and improves the operability, accuracy and safety of the operation.

Description

technical field [0001] The invention relates to surgical instruments in the medical field, and mainly relates to an ultrasonic acetabular file and a file head suitable for minimally invasive total hip replacement. Background technique [0002] Artificial total hip replacement is a treatment for patients with hip joint lesions. Artificial hip replacement uses materials with good biocompatibility and mechanical properties to make a prosthesis, and the joint prosthesis is implanted into the damaged joint through surgery. place, an artificial prosthesis replaces the joint, eliminating pain and restoring mobility. During the operation, the acetabular reamer is used to ream the acetabulum, remove the articular cartilage and subchondral bone, and ream the surface of the acetabulum to better match the artificial prosthesis. The current acetabular reamers are connected to the rotating motor head, and the acetabular reamer can be quickly rotated and reamed in a small surgical space b...
