Embodiment 1

[0033] Such as figure 1 with Figure 9 As shown, an acetabular labrum processor for hip joint replacement surgery includes a handle 1, a control handle 2, a first connecting rod 3, a second connecting rod 4 and a cutter head 5; the handle 1 passes through The first connecting rod 3 is connected to the control handle 2, and the control handle 2 is connected to the cutter head 5 through the second connecting rod 4; the handle 1 is spherical, the control handle 2 is flat hexagonal, and the first connection The rod 3 is a short straight rod, and the second connecting rod 4 is a straight rod.

[0034] Such as figure 2 with image 3 As shown, the cutter head 5 is a cuboid frame structure, and the angle between the bottom frame 501 and the horizontal plane is 15°; the cutter head 5 is 5-8mm wide, 8-10mm long, and the height of the right frame is The thickness of each frame is 10mm, and the thickness of each frame is 3-5mm; the bottom frame 501 is an isosceles triangular prism st...

Embodiment 2

[0038] Such as Figure 4 , Image 6 with Figure 9 As shown, an acetabular labrum processor for hip joint replacement surgery includes a handle 1, a control handle 2, a first connecting rod 3, a second connecting rod 4 and a cutter head 5; the handle 1 passes through The first connecting rod 3 is connected to the control handle 2 , and the control handle 2 is connected to the cutter head 5 through the second connecting rod 4 . The handle 1 is spherical, the control handle 2 is flat hexagonal, and the first connecting rod 3 is a short straight rod. Such as Figure 5 with Figure 7 As shown, the second connecting rod 4 is an angle bending rod, which is an integrated natural bending without interruption in the middle, its upper half is vertical, and the acute angle formed by the lower half and the upper half is 10- 30°, in order to achieve the required mechanical strength requirements during the cutting process. The handle 1, the control handle 2, the first connecting rod 3...

Abstract

The invention provides an acetabular labrum treater for use in hip-joint replacement surgery. The acetabular labrum treater comprises a holding handle, a control handle, a first connecting rod, a second connecting rod and a tool bit, wherein the holding handle is connected with the control handle through the first connecting rod; the control handle is connected with the tool bit through the second connecting rod; the tool bit has a frame type structure; an angle between a bottom border the tool bit and a horizontal plane is an acute angle; at least one long edge of the bottom border is a sharp edge; the second connecting rod can be a straight rod or an angular bent rod. Through application of the treater to the hip-joint replacement surgery, quick, clean and neat removal of acetabular labrum can be realized, and good preparation is made for subsequent surgical steps.

Description

technical field [0001] The invention belongs to the field of medical surgical instruments, in particular to an acetabular labrum processor used in hip joint replacement surgery. Background technique [0002] Hip replacement is a revision surgery in which all or part of the hip joint is replaced with an artificial hip prosthesis to restore joint movement. For example, hip osteoarthritis, aseptic necrosis of the femoral head, femoral neck fracture, etc., all require hip replacement under certain conditions. In hip replacement surgery, it is necessary to grasp and determine the abduction angle and anteversion angle according to the shape of the acetabulum in order to obtain a stable joint after surgery. However, in many cases, exposure is difficult due to the obstruction of the acetabular labrum soft tissue or local bone hyperplasia, which affects the judgment of the angle during the acetabular grinding process during the operation. Implantation of the acetabular prosthesis a...
