METHODS AND DEVICES FOR CONTROLLING MOTORIZED SURGICAL DEVICES

摘要

Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device can include at least one sensor and a motor, and an output of the motor can be configured to be adjusted based at least in part on an output from the at least one sensor. The output of the motor can be configured to provide power for translation of a cutting element along an end effector of the device. Adjusting the motor's output can cause the cutting element to translate through the end effector at different speeds, thereby allowing the cutting element to cut through tissue being grasped by the end effector at different speeds.

主权项

1. A surgical device, comprising:
a proximal portion configured to be handheld; a distal portion including a working end configured to be advanced into a body of a patient, the working end being configured to be movable relative to the proximal portion using electronic power supplied to the surgical device from a motor; a cord extending from the proximal handle portion such that a free end of the cord is external to the proximal handle portion, the free end of the cord being configured to be selectively operatively connected to and not operatively connected to a generator; and a power source configured to provide power to the motor, the power source being external to the proximal handle portion and being attached to the cord adjacent the free end.
