Abstract

The invention provides a guiding device for the pelvic tumor osteotomy, which comprises a handle and a guiding part. The guiding part is divided into a front part and a rear part which are connected; the front part is of a hook shape; the rear part is of a straight line shape; one end of the rear part is connected with the front part; the other end of the rear part is connected with the handle; a cavity running through the front part is arranged in the front part of the guiding part; the front part is provided with an inlet hole and an outlet hole which are communicated with the cavity; the inlet hole is arranged at the end of the front part, which is connected with the rear part, or is arranged on the rear part; and the outlet hole is arranged at the end of the front part, which is far away from the front part. According to the guiding device for the pelvic tumor osteotomy, which is provided by the invention, aiming at the complex anatomical features of the pelvis, the problem of difficulty in reasonably cutting bones totally according to a pre-operation plan is solved, the problem of insufficient cutting of the tumor or excessive cutting of the normal bone tissues in the operating process can also be solved, the possibility of damage to adjacent organs can also be reduced, and the unnecessary operation complications are reduced.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a guide for pelvic tumor osteotomy and a tool kit including the guide. Background technique [0002] Bone tumors that occur in the pelvis mainly include: osteosarcoma, chondrosarcoma, Ewing's sarcoma, lymphoma, myeloma, and metastatic cancer. Limb-salvage surgery for malignant bone tumors of the pelvis is extremely challenging due to the complex anatomy of the pelvic region. In the early reports, the fatal complications were as high as 10%, the overall complications were as high as 75%, and the 5-year survival rate was about 25% to 35%. With the improvement of technology, surgical complications have gradually decreased. Overall complications were reduced to 33% (23% of which were wound complications), the local recurrence rate was 17%, the overall 5-year survival rate was about 37%, and the perioperative mortality rate was close to zero. [0003] At present, pelvic ...
