The application discloses a kind of laser scanning cutting endoscope robots based on carbon fiber paper micro-vibration mirror, the endoscope robot is fixedly installed with paper transmission structure in one end of support structure, and the other end is fixedly installed with GRIN lens;Fixed mirror, X galvanometer and Y galvanometer are fixedly installed in paper transmission structure, and optical path is formed by optical fiber, GRIN lens, fixed mirror, X galvanometer and Y galvanometer;First piezoelectric bimorph driver and second piezoelectric bimorph driver are piezoelectric bimorph driver installed between support structure and paper transmission structure;First piezoelectric bimorph driver is used to drive X galvanometer to rotate around Y axis and / or by paper transmission structure;Second piezoelectric bimorph driver is used to drive Y galvanometer to rotate around Z axis by paper transmission structure.The above-mentioned endoscope robot is compact, light, stable in motion and has excellent dynamic performance by using piezoelectric bimorph driver and paper transmission structure.

The application provides a surgical instrument and a computer-aided medical system with a wider motion space, which comprises an execution member and a clamp assembly, an instrument rod, a two-degree-of-freedom wrist joint assembly, a first transmission assembly, a second transmission assembly, and an execution member driving mechanism and a wrist joint driving mechanism. The execution member driving mechanism comprises a rack movable along the length direction of the instrument rod. The proximal end of the first transmission assembly is connected to the rack through the instrument rod, the distal end of the first transmission assembly is connected to the execution member through the wrist joint assembly, and the proximal end of the second transmission assembly is connected to the wrist joint driving mechanism through the instrument rod. Wherein, the rack drives the execution member to move between the distal end and the proximal end of the clamp assembly through the first transmission assembly, and the wrist joint driving mechanism drives the deflection of the wrist joint assembly through the second transmission assembly.

This invention discloses a multi-degree-of-freedom hybrid manipulator and its usage method, relating to the field of manipulator technology. The manipulator includes a turntable mechanism, with a hybrid arm mechanism positioned above the turntable mechanism and a mechanical gripper mechanism connected below it via a buffer mechanism. The turntable mechanism includes a turntable, with a fixed ring rotatably connected to its outer side. Multiple insertion holes are evenly distributed in a ring along the circumference on the inner side of the fixed ring. A cross-shaped groove is formed inside the turntable, and a trapezoidal block with an upward-sloping bevel is slidably positioned near the end of each groove. Insertion rods extending to the outer surface of the turntable are mounted on the sides of the trapezoidal blocks, and return springs are sleeved on the insertion rods. The manipulator of this invention uses insertion rods inserted into the insertion holes of the fixed ring within the turntable to self-lock the turntable, eliminating the need for the motor drive end to prevent object rotation, reducing the force on the motor drive end, and extending the service life of the rotary motor.
