ELECTROMECHANICAL ACTUATOR DEVICE FOR USE WITH ANASTOMOSIS, STAPLING AND RESECTION INSTRUMENTS.

摘要

Clamping and linear stapling instrument (180), anastomosis and stapling instrument (200), each presenting different functions, and electromechanical actuator (100) for remotely operating the instruments (180, 200), presenting the instruments (180 , 200) rotating elements (158a, 158b, 206a, 206b) therein, the electromechanical actuator (100) comprising a flexible shaft (122) and a handle part (102), including the flexible shaft (122) at least two axially rotating and flexible elements (136a, 136b) disposed within the flexible shaft (122), said rotating elements (136a, 136b) having distal and proximal ends, each rotating element (136a, 136b) being able to transmit an applied torque to the proximal end thereof along it to said distal end thereof, said distal ends including means for engaging said corresponding rotating elements (158a, 158b, 206a, 206b) of the inst surgical routes (180, 200), characterized in that the handle part (102) has an engine arrangement comprising at least two selectively geared motors (110, 112) arranged in the handle part (102) and coupled with the elements corresponding of said rotary elements (136a, 136b), the selective gearing of any of said at least two motors (110, 112) rotating the corresponding rotary element (136a, 136b), thus transmitting a torque to an element corresponding swivel (158a, 158b, 206a, 206b) of the instruments (108, 200), and because the instruments (180, 200) are each accessories that have a coupling interface (154, 203) conceived in common that is adapted to join the electromechanical actuator (100) and because the electromechanical actuator (100) can be reused to activate the different functions of each instrument (180, 200), so that the different functions of the instruments Mentos (180, 200) are only specific to the accessories.
