Abstract

The embodiment of the invention provides a fusion cage holding device which comprises a handheld assembly and a holding assembly connected to each other, wherein the holding assembly comprises a holding sleeve and a connecting rod assembly; the holding sleeve is provided with a first end at the near side, a second end at the far side and a bent part close to the second end; the connecting rod assembly is contained in the holding sleeve in a circumferential rotation mode and comprises a first connecting rod and a second connecting rod which are hinged in a synchronous rotation mode; the end, far away from the second connecting rod, of the first connecting rod is connected to the operation end so as to actuate the first connecting rod to rotate through the operation end, and the second connecting rod is provided with a connecting end used for being connected with the fusion cage. Through the bending part on the holding sleeve, when a doctor performs a lumbar interbody fusion operation on the gap between the fifth lumbar vertebra and the sacral vertebra, the shielding of the iliac bone can be avoided without hurting the iliac bone, so that the doctor is helped to perform the operation smoothly; and the connecting rod assembly capable of rotating in the circumferential direction can realize the holding and implanting operation of the fusion cage holding device on the fusion cage.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fusion device holding device. Background technique [0002] Lumbar disc herniation is more likely to occur in the gap between the fourth lumbar vertebra and the fifth lumbar vertebra and the gap between the fifth lumbar vertebra and the sacral vertebra. Due to the influence of the upper body weight, the gap between the fourth lumbar vertebra and the fifth lumbar vertebra and the fifth The gap between the lumbar spine and the sacrum is just at the bottom of the spine, so it is under greater pressure, which is very easy to cause disc degeneration and disc herniation. At the same time, the lumbar spine protrudes forward and the sacrum protrudes backward. Physiological radian, the sacrum and the ilium form a pelvic ring, the sacrum is relatively stable, and the lumbar spine is movable. Such a turning area makes the gap between the fifth lumbar vertebra and the sacrum mo...
