Sacrum fixing bracket

Abstract

The invention provides a sacrum fixing bracket. The sacrum fixing bracket comprises fixing plates (1), support rods (2) and patches (4), wherein the plurality of support rods (2) comprise first support rods (21) and second support rods (22), and the first support rods (21) and the second support rods (22) are parallel to each other or have included angles in the axial extension direction; the patches (4) are arranged between the first support rods (21) and the second support rods (22); each support rod (2) comprises a rod head part (201), a rod body part (202) and a rod tail part (203); the rod head part (201), the rod body part (202) and the rod tail part (203) are connected in sequence; each fixing plate (1) is connected with the corresponding rod head part (201); the rod tail part (203)of each first support rod (21) is connected with the rod tail part (203) of the corresponding second support rod (22). For the sacrum fixing bracket, cut-off grooves are arranged in each fixing plate, the fixing position of each fixing plate on the ilium is adjusted according to use demands, the redundant parts of the fixing plates are cut off, and thus the surgeries with different sacrum cut-offlengths are adapted.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sacral fixation bracket. Background technique [0002] About 1% to 7% of primary spinal tumors occur in the sacrum. According to literature reports, extended tumor resection is the best treatment to reduce the recurrence rate, and partial or even total sacral resection is often required to achieve extended tumor resection. Due to the complex anatomical location near the sacrum, extended resection of sacral tumors is accompanied by many complications, including massive blood loss, wound infection, nerve function damage, and pelvic structure destruction. [0003] As we all know, the maintenance of defecation function requires the normal anatomical shape and function of the levator ani muscle, and the integrity of the pelvic floor muscle is also a prerequisite for the normal support of the pelvic floor. However, during a sacrectomy, the pelvic floor muscles will inevitably lose th...

Problems solved by technology

According to the patent literature, it can effectively solve the problem of unreliable support and easy fatigue fracture of the nail-rod system in the prior art.

However, the structure provided by this patent document cannot effectively adapt to different sacrum and ilium sizes of different patients, and the length of sacrum resection during surgery is not fixed, and the specification and installation position of the sacral prosthesis itself are difficult to achieve flexible adjustment.
