The invention discloses a high-performance polyphenyl ether material and a preparation method thereof.The preparation method comprises the steps that modified polyphenyl ether reacts with a modified additive, bromine atom sites on the modified polyphenyl ether react with phenolic hydroxyl groups on the modified additive, then the product is mixed with modified carbon nanotubes, a cross-linking agent and benzophenone, a mixture is prepared, the mixture is subjected to vacuum drying, and the high-performance polyphenyl ether material is obtained. The preparation method comprises the following steps: modifying carbon nanotubes and modified polyphenyl ether, reacting under the condition of ultraviolet irradiation to prepare the high-performance polyphenyl ether material, reacting double bonds on the modified carbon nanotubes and double bonds on the modified polyphenyl ether with sulfydryl on a cross-linking agent during ultraviolet irradiation to further form dynamic cross-linking, dissipating energy through dynamic bond exchange, actively relaxing stress and passivating cracks, and preparing the high-performance polyphenyl ether material. The modified polyphenyl ether reacts with the modified additive to form a cross-linked network, and the modified additive is an organic silicon elastomer and can serve as a stress concentration point to induce a matrix to generate a large amount of crazing and shear bands, so that a large amount of energy is absorbed, and cracks are prevented from further expanding.

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.
