Abstract

The invention relates to the technical field of surgical instruments, in particular to a bone joint, a vertebra joint assembly and a surgical instrument. The bone joint comprises a traction part, a first spherical surface and a second spherical surface, wherein a first through hole and a plurality of second through holes penetrating through the first spherical surface and the second spherical surface are formed in a traction part in an axial direction. The vertebra joint assembly comprises an end joint, a tail joint, a plurality of traction lines and a middle joint formed by sequentially connecting a plurality of joints, and the traction lines are fixedly connected with the end joint and sequentially penetrate through the middle joint and the tail joint. The vertebra joint assembly is applied to the surgical instrument, bending of the vertebra joint assembly in the surgical instrument can drive the tail end operation assembly to deflect in any direction and achieve free rotation, and the bending radius of the vertebra joint assembly is small, so that vertebra joint bending is more flexible; the focus of a patient can be observed more accurately through the endoscope, and finer surgical operation is achieved.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a joint, a vertebral joint assembly and a surgical instrument. Background technique [0002] During the diagnosis and treatment of abdominal minimally invasive surgery, doctors usually use the multifunctional channeler of the soft tissue robot to send surgical instruments with flexible functions into the patient's abdomen for surgery. [0003] Due to the small space in the patient's abdomen, in order to meet the doctor's fine manipulation of the lesion during the operation, the bending radius of the flexible functional structure of the surgical instrument has a high requirement. At present, the flexible function of surgical instruments is mainly realized through the vertebral joint structure. [0004] However, the existing vertebral joint structure can only guarantee the basic flexible function of the operation, and cannot better meet the bending radius required for...
