Title: FLEXIBLE SURGICAL INSTRUMENT SYSTEM BASED ON CONTINUOUS BODY STRUCTURE
Abstract:
Disclosed is a flexible surgical instrument system based on a continuous body structure. The flexible surgical instrument system comprises a flexible surgical instrument (10) and a driving unit (20). The flexible surgical instrument (10) comprises a flexible continuous body structure composed of a distal structural body (101), a proximal structural body (102) and a middle connecting body (103). The distal structural body (101) comprises distal structural segments (104, 105), the distal structural segments (104, 105) each comprising a distal spacer plate (106, 109), a distal fixed plate (107, 110) and a structural bone (108, 111). The proximal structural body (102) comprises proximal structural segments (112, 113), the proximal structural segments (112, 113) each comprising a proximal spacer plate (114, 117), a proximal fixed plate (115, 118) and a structural bone (116, 119). The middle connecting body (103) comprises a channel fixing plate (120) and a structural bone guiding channel (121). The driving unit (20) comprises an electric motor part (206), a motion conversion part (207) and a plurality of linear motion mechanisms (201). The electric motor part (206) comprises a first fixed plate (208) and a first electric motor (209). The motion conversion part (207) comprises a plurality of transmission chains (210). Each transmission chain (210) converts a rotation output from the first electric motor (209) into linear motions of two output rods (221, 222), and transfers same to input ends of the linear motion mechanisms (201) by means of a sterile barrier (223). Output ends of the linear motion mechanisms (201) are connected to one end of one driving bone (202), the driving bone (202) passes through the proximal spacer plates (114, 117), and the other end of the driving bone is connected to the proximal fixed plates (115, 118).
