Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] The invention consists of a sacrum and lumbar connection device, a large pelvis replacement device, a femur and ischium connection device and the like.

[0028] Referring to accompanying drawing 1, the femur and ischium connection device adopts the femur and ischium connection device in "artificial pelvic prosthesis" (patent application number 200420016475.1) and "artificial ilium replacement device" (patent application number 200410064519.2) invented by myself. The femur and ischium connecting device is composed of spherical cup 4, artificial femoral head and handle 5, the lower end of spherical cup 4 is connected with artificial femoral head and handle 5, and the upper end is connected with inner connecting sleeve 3. The device is connected with the femoral reserved bone through the artificial femoral head and the handle 5 . Through t...

Description

technical field [0001] The invention relates to the medical field of bone defect reconstruction caused by extensive resection of pelvic tumors and metastatic cancers invading the pelvis, in particular to a multifunctional large pelvic artificial prosthesis for reconstruction of large pelvic defects. Background technique [0002] The human pelvis is composed of left and right hip bones, sacrum, coccyx and associated ligaments, and can be divided into two parts: the large pelvis and the small pelvis. The pelvis is an important part of the connection between the trunk and the lower limbs. It is characterized by: [0003] 1. The pelvis is the largest flat bone group in the human body, containing a large amount of cancellous bone, which is filled with functional bone marrow. [0004] 2. The pelvis is the main weight-bearing part of the human body, bearing the body weight transmitted from the spine to the sacrum. [0005] 3. There are many important organs, blood vessels and ner...
