Embodiment Construction

[0025] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] The artificial isthmus prosthesis according to the embodiment of the present invention, such as figure 1 As shown, it includes: an isthmus body part 10 and a fixing part 20, the isthmus body part 10 is used to be arranged at a preset position in the femoral medullary canal 40, and the isthmus body part 10 has an isthmus body structure adapted to the femoral stem; The fixing part 20 is detachably connected to the isthmus body 10 to fix the isthmus body 10 at a preset position.

[0027] The artificial isthmus prosthesis applying the technical solution of the present invention includes: an isthmus body 10 and a fixing portion 20, the isthmus body 10 is used to be arranged at a preset posit...

Abstract

The invention provides an artificial isthmus prosthesis. The artificial isthmus prosthesis comprises an isthmus portion and a fixing portion. The isthmus portion is arranged at a preset position in afemoral marrow cavity, and is provided with an isthmus structure matched with femoral components. The fixing portion is detachably connected with the isthmus portion to fix the isthmus portion to thepreset position. The artificial isthmus prosthesis has the advantages that the isthmus of a patient is reconstructed in case of isthmus damage or loss of the patient during artificial hip replacement,and accordingly, sinking of the femoral components is avoided; the problem of proneness to femoral component sinking due to isthmus damage or loss of the patient during artificial hip replacement inthe prior art is solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an artificial isthmus prosthesis. Background technique [0002] Total hip arthroplasty (THA) is one of the most successful surgical procedures in the 20th century. It can effectively eliminate joint pain, reconstruct joint function and correct deformity, thereby improving the quality of life of patients. There are different forms of hip joint lesions, especially the treatment of patients with severe femoral shaft defects has always been one of the most difficult problems for clinicians. If not handled properly, patients will suffer disastrous consequences. [0003] Viewed from the proximal end to the distal end, the diameter of the femoral medullary cavity is from large to small and then to large. In the medullary cavity, with the smallest diameter as the zero line, the cancellous bone segment extending several centimeters to the proximal and distal ends is called the isthmus of...
