Therefore, we need an auxiliary prosthesis that is convenient for surgery.

[0003] After searching, a Chinese patent with publication number CN208926600U discloses a universally bendable minimally invasive surgical manipulator. The utility model controls the bending of the bending arm by stretching the first tension member, and at the same time drives the swing rod to rotate and the second tension member to stretch by rotating the flexible shaft to control the opening and closing of the clamp, so that the bending of the bending arm and the opening and closing of the clamp do not interfere with each other. However, the following defects still exist: it is difficult to adjust the extended length of the clamp, it is difficult to meet different clinical needs, and the practicality is poor.

The other end of the connecting shaft is fixed with a disk by bolts, and one end of the disk is fixed with a rotating disk by bolts. The circumferential outer wall of the connecting shaft is provided with a positioning component that enables the disk to rotate at a fixed angle.

[0007] As a further solution of the utility model, the positioning component is a second mounting shell, which is rotatably connected to the circumferential outer wall of the connecting shaft, and the connecting shaft is fixed to the supporting shell. A mounting groove is provided on one side of the supporting shell, a spring is welded in the mounting groove, a positioning bead is welded at one end of the spring, and a positioning groove is provided at the bottom of the disc, and the positioning groove is in contact with the positioning bead.
