Abstract

The invention discloses an adjustable sacral osteotomy guide plate, which comprises a first guide plate, a second guide plate, a third guide plate and a guide groove extension block; the first guide plate and the third guide plate are respectively hinged to the second guide plate, and the third guide plate is connected to the The two guide plates are slidingly connected, and the third guide plate approaches or moves away from the first guide plate during sliding movement; the cross section of the second guide plate is "convex", including the first member and the second member, and the thickness of the first member is greater than the thickness of the second member The guide groove extension block is arranged on the second member, which can be switched between the first position and the second position. When it is at the first position, the first member is in contact with the third guide plate. When it is at the second position, the second A member is not in contact with the third guide plate. In the present invention, the first guide plate and the third guide plate are hinged on both sides of the second guide plate, and the third guide plate slides on the second guide plate toward or away from the first guide plate, so that the position can be flexibly adjusted during the osteotomy operation And angle, easy to operate, flexible, low cost.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an adjustable sacral osteotomy guide plate. Background technique [0002] The sacrum is one of the important bones that make up the pelvis. It assists in connecting the trunk and lower limbs, plays an important role in supporting and protecting the organs and soft tissues in the pelvis, and also plays an important role in maintaining the balance of the human body. The sacrum is formed by the fusion of five sacral vertebrae in an inverted triangle shape and is divided into the base of the sacrum, the side, the tip of the sacrum, the pelvic surface, and the dorsal surface. The incidence of sacral tumors is mainly the primary malignant tumor. The early symptoms are not obvious, and the tumor volume is usually large when it is discovered. Surgical resection is the best treatment for sacral tumors. However, the anatomical structure around the sacrum is complex and ...
