Electro-mechanical surgical device
View Patent ↗An electro-mechanical surgical device includes: a housing; an elongated shaft extending from the housing, a distal end of the elongated shaft being detachably coupleable to a surgical instrument; at least two axially rotatable drive shafts disposed within the elongated shaft, a distal end of each of the drive shafts being configured to couple with the surgical instrument; a steering cable arrangement, the steering cable arrangement being configured to steer the distal end of the elongated shaft; and a motor system disposed within the housing, the motor system being configured to drive the drive shafts and the steering cable arrangement. A control system may be provided for controlling the motor system. A remote control unit may also be provided for controlling the motor system via the control system. Sensors, such as optical or Hall-effect devices, may be provided for determining the position of the elements of the surgical instrument based on the detected rotation of the drive shafts. A memory unit stores a plurality of operating programs or algorithms, each corresponding to a type of surgical instrument attachable to the electro-mechanical surgical device. The control system reads or selects from the plurality of operating programs or algorithms, the operating program or algorithm corresponding to the type of surgical instrument attached to the electro-mechanical surgical device.
1. A surgical instrument for use with an electro-mechanical surgical device, comprising:
a coupling configured to couple the surgical instrument with the electro-mechanical surgical device;
a memory unit configured to store a first data representing a type of the surgical instrument; and
at least one rotatable drive shaft configured to couple with a respective drive shaft of the electro-mechanical surgical device;
wherein the coupling includes a data connector configured to connect the memory unit with the electro-mechanical surgical device.
2. The surgical instrument according to claim 1 , wherein the at least one rotatable drive shaft includes a first rotatable drive shaft and a second rotatable drive shaft, each of the drive shafts being configured to couple with a respective drive shaft of the electro-mechanical surgical device.
3. The surgical instrument according to claim 1 , wherein the memory unit is configured to store a second data representing a usage of the surgical instrument.
4. The surgical instrument according to claim 1 , wherein the first data is readable by a control system of the electro-mechanical surgical device.
5. The surgical instrument according to claim 3 , wherein at least one of the first data and the second data is readable by a control system of the electro-mechanical surgical device.
6. The surgical instrument according to claim 1 , wherein the data connector is configured to electrically and logically connect the memory unit to a control system of the electro-mechanical surgical device.
7. The surgical instrument according to claim 1 , wherein the coupling is configured to detachably attach the surgical instrument to the electro-mechanical surgical device.
8. The surgical instrument according to claim 1 , wherein the surgical instrument includes a surgical stapler/cutter instrument.
9. The surgical instrument according to claim 8 , wherein the surgical stapler/cutter instrument includes an anvil portion and a staple driver/cutter portion.
10. The surgical instrument according to claim 9 , further comprising a first rotatable drive shaft configured to open and close the anvil portion and a second rotatable drive shaft configured to drive the staple driver/cutter portion.
