Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of postoperative fixing structures, in particular to a postoperative fixing structure for total hip replacement. Background Art
[0002] Hip replacement, also known as artificial hip replacement, is an artificial prosthesis, including the femoral part and the acetabulum part, which is fixed to normal bone using bone cement and screws to replace the diseased joint and reconstruct the normal function of the patient's hip joint. It is a relatively mature and reliable treatment method. After hip replacement, a postoperative fixation structure is often required to fix the patient's legs for easy recovery. There are at least the following disadvantages in the use of existing postoperative fixation structures: During use, most of the existing postoperative fixation structures place a rectangular block between the patient's legs and then fix it with a strap. It is not only easy to loosen, but also has limited fixation on the legs, affecting the fixation effect. Therefore, we have introduced a postoperative fixation structure for total hip replacement. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A postoperative fixation structure for total hip replacement comprises a No. 1 fixing piece, wherein the middle part of the right end and the rear part of the right end of the No. 1 fixing piece are fixedly connected with an adjusting rod, and two adjusting rods are interspersed and movably connected with a No. 2 fixing piece, and the No. 2 fixing piece is a structure that is narrow in front and wide in back, and a No. 1 arc groove is opened on the right part of the upper end of the No. 2 fixing piece, and two No. 1 straps are fixedly connected to the upper end of the No. 2 fixing piece, and the No. 1 fixing piece is a structure that is narrow in front and wide in back, and a No. 2 arc groove is opened in the middle part of the upper end of the No. 1 fixing piece, and two No. 2 straps are fixedly connected to the upper end of the No. 1 fixing piece, and the inner walls of the two No. 2 straps and the inner walls of the two No. 1 straps are fixedly connected with Velcro fur surfaces, and the left end of the No. 1 fixing piece and the right end of the No. 2 fixing piece are fixedly connected with two Velcro hook surfaces.
[0006] Preferably, two slide grooves are formed at the left end of the second fixing member.
[0007] Preferably, the right ends of the two adjusting rods are fixedly connected to the limiting circular blocks.
[0008] Preferably, the two limiting round blocks and the two adjusting rods are respectively and movably connected with the two sliding grooves.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] By setting a No. 1 fixing piece and a No. 2 fixing piece, since the No. 1 arc groove is formed on the No. 2 fixing piece and the No. 1 fixing piece is formed on the No. 2 arc groove, the patient's legs can be placed in the No. 2 arc groove and the No. 1 arc groove to lift the patient's legs, and then the upper part of the patient's legs can be limited by two No. 1 straps and two No. 2 straps, so that the patient's legs can be fixed, which improves the convenience of fixation, and by interlacing and connecting two adjustment rods with the No. 2 fixing piece, the No. 1 fixing piece and the No. 2 fixing piece can be pulled to make the two adjustment rods move in the No. 2 fixing piece, so that the distance between the No. 1 fixing piece and the No. 2 fixing piece can be adjusted, which improves the flexibility of use.
