Loading unit detection assembly and surgical device for use therewith
First Claim
Patent Images
1. A surgical device, comprising:
- a device housing defining a connecting portion for selectively connecting with an adapter assembly;
at least one drive motor supported in the device housing and being configured to rotate at least one drive shaft;
a battery disposed in electrical communication with the at least one drive motor;
a circuit board disposed within the device housing for controlling power delivered from the battery to the at least one drive motor;
a loading unit configured to perform at least one function;
an adapter assembly for selectively interconnecting the loading unit and the device housing; and
a loading unit detection assembly disposed in mechanical cooperation with the adapter assembly, the loading unit detection assembly including;
a detection link configured to be engaged by the loading unit, the detection link being longitudinally translatable with respect to the loading unit;
a switch pin disposed in mechanical cooperation with the detection link, such that longitudinal translation of the detection link results in a corresponding longitudinal translation of the switch pin; and
a switch button disposed in mechanical cooperation with the adapter assembly;
wherein a predetermined amount of mechanical engagement between the loading unit and the loading unit detection assembly causes proximal translation of the detection link and causes the switch pin to move proximally into contact with the switch button, and wherein a predetermined amount of force exerted by the switch pin against the switch button activates the switch button, which electronically communicates with a portion of the device housing to permit actuation of the at least one drive motor.

12. An adapter assembly including a loading unit detection assembly, the adapter assembly configured to operably couple a surgical device to a loading unit, the surgical device including a drive motor configured to rotate a drive shaft, the loading unit detection assembly comprising:
-
a detection link configured to be engaged by the loading unit; a switch pin disposed in mechanical cooperation with the detection link such that longitudinal translation of the detection link results in a corresponding longitudinal translation of the switch pin; and a switch button disposed proximally of the switch pin; wherein engagement between the loading unit and the loading unit detection assembly causes the detection link and the switch button to proximally translate with respect to the loading unit such that the switch pin engages the switch button, and wherein engagement of the switch button with a predetermined amount of force from the switch causes an electronic communication from the loading unit detection assembly with a portion of the surgical device to permit actuation of the loading unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
