Publication number: 20230371942Abstract: Surgical tools that are capable of both manipulating a needle and cutting surgical thread during a suturing operation can sometimes be problematic due to inadvertent severing of the surgical thread. Surgical tools capable of exposing a bladed cutting surface only when severing of surgical thread is desired can substantially alleviate this issue. Such surgical tools may comprise an end effector comprising an end effector axle, a first jaw and a second jaw rotatably mounted to the end effector axle, and a first cutting body having a first blade and second cutting body having a second blade. The first cutting body is configured to move in tandem with the first jaw and the second cutting body is configured to move in tandem with the second jaw, such that the first and second blades are occluded when the first and second jaws are closed or partially opened.Type: ApplicationFiled: August 7, 2023Publication date: November 23, 2023Inventors: Andrew Crews, Michael Chirumbolo, John A.

Patent number: 11642163Abstract: 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.
