The utility model relates to an adaptive device and a surgical robotic.The adaptive device comprises a cannula, a sterile
isolator and a base, the cannula comprises a cannula body and a cannula base, the cannula body is arranged on the cannula base and provided with a cannula cavity allowing a
surgical instrument to penetrate through, the sterile
isolator comprises a flexible sleeve, the flexible sleeve is arranged between the base and the cannula base, the cannula base is connected with the base in a clamped mode through the flexible sleeve, and the sterile
isolator is arranged in the cannula cavity. The sleeve and the base are isolated in a sterile mode. The tube body is used for penetrating through surgical instruments such as an
endoscope, the tube body is arranged on the tube base, the tube base is connected with the base in a clamped mode, the sleeve and the base can be disassembled and assembled more conveniently through the clamping mode, and rapid adaptive disassembly and
assembly of the sleeve and the base are achieved; the sterile isolator comprises a flexible sleeve, the flexible sleeve is arranged between the base and the tube seat, the tube seat is connected with the base in a clamped mode through the flexible sleeve, the flexible sleeve can achieve sterile isolation between the base and the sleeve and reduce infection, meanwhile,
friction force among the tube seat, the flexible sleeve and the base can be increased through flexible deformation, and the clamping fixing effect is better.
