Description
Technical Field
The invention relates to the field of medical operation tools, in particular to a femoral neck osteotomy baffle plate in hip joint replacement.
Background
The anatomical basis is as follows: the diameter of femoral head is (46.69 + -3.73) mm; the longitudinal length of the femoral head is (39.22 +/-4.17) mm; the length of the head and neck axis is (95.45 +/-8.16) mm; the length of the upper edge of the head and neck shaft is (84.02 +/-7.11) mm. The length of the lower edge of the head neck shaft is (99.95 +/-9.34) mm; the anterior-posterior diameter of the femoral neck is (26.27 +/-3.15) mm; the longitudinal diameter of the femoral neck is (32.24 +/-3.31) mm; the angle of the shaft is (l26.21 +/-7.13).
In hip replacement surgery, the hip joint is first exposed, followed by resection of the femoral neck and removal of the femoral head to expose the acetabulum. When the femoral neck is cut in the hip joint replacement operation, an assistant uses a hip joint draw hook to insert the hip joint draw hook into a gap between the femoral neck and a glenoid, the femoral neck is slightly jacked up by using the tip of the hip joint draw hook, meanwhile, part of the inner side wall of the femoral neck is shielded, and then the femoral neck is cut by using a swing saw. However, this solution has the following problems during the operation: 1. in the operation process, usually, an operator judges whether the femoral neck is cut off completely according to the falling feeling of the swing saw, but the operator is influenced by inertia, if the swing saw cannot be withdrawn in time, the structural tissue behind the femoral neck is easily damaged, and the subsequent operation cannot be normally performed; 2. the shielding area of the tip of the hip joint draw hook used at present to the inner side wall of the femoral neck is small, so that the protection effect is difficult to play, and the femoral neck is supported by the tip of the hip joint draw hook tip, so that the femoral neck is difficult to fix and reduce the swing. Therefore, the existing hip joint draw hook is difficult to quickly, accurately and safely complete the femoral neck osteotomy.
Disclosure of Invention
The invention aims to provide a femoral neck osteotomy baffle plate in hip joint replacement, which embraces the femoral neck through a set shielding part, can protect a glenoid and the musculature at the back of the femoral neck, can fix the femoral neck to reduce swing, solves the problem that a swing saw easily damages the structural tissue at the back of the femoral neck when the femoral neck is osteotomy is carried out in the hip joint replacement operation, and is beneficial to safely and effectively finishing the femoral neck osteotomy.
The purpose of the invention is realized as follows:
the utility model provides a thighbone neck cuts bone baffle in hip joint replacement art, includes the handle, the front end shaping of handle has the shielding part that extends to the kickup through a straight line extension section to the kickdown, the width of shielding part is 25 ~ 28mm, and the shielding part is the arc bending section, and the radius of this arc bending section is 25mm, and the central angle of arc bending section is 140, the front end of arc bending section includes that the width is less than the guide portion of shielding part width, forms integrated into one piece's thighbone neck cuts bone baffle.
The downward bending part is arc-shaped and bent, so that the handle and the linear extension section form an included angle of 130 degrees.
The width of the narrowest part of the downward bending part is 15-20 mm, two side edges of the downward bending part are forward in an arc shape and smoothly transited to a straight extension section, the arc bending angle is 130 degrees, and the two side edges of the downward bending part gradually widen backwards and are connected with the handle.
The length of the straight extension section is 70-75 mm, and the width is 25-28 mm.
The length of the guide part is 25mm, the width of the guide part is gradually narrowed from 25-28 mm to 5-6 mm from the front end, and the end part is passivated.
