Surgical device and surgical robot

Abstract

The utility model relates to the field of medical apparatus and instruments, especially a surgical device and surgical robot. The surgical device comprises a surgical instrument and a sheath, the surgical instrument comprises a distal end executor, a movable joint and a connecting rod connected in sequence from the distal end to the proximal end, the sheath is made of flexible insulating material, and the sheath comprises a sheath body, a first connecting piece and a second connecting piece. The sheath body is used for coating the movable joint, the first connecting piece and the second connecting piece are fixedly connected to the distal end and the proximal end of the sheath body respectively, the first connecting piece and the distal end executor form a limiting cooperation along the axial direction of the sheath when the sheath is sleeved on the surgical instrument, the second connecting piece and the connecting rod are locked through a clamping structure, and the clamping structure responds to the radial deformation of the second connecting piece to release the locking state of the second connecting piece and the connecting rod. The first connecting piece of the sheath and the distal end executor form axial limiting cooperation, the second connecting piece and the connecting rod are locked through the clamping structure, and the stable connection of the sheath on the surgical instrument is realized.
