A surgical instrument includes first and second shaft members defining proximal and distal end portions and including handles at the proximal end portions thereof. A pivot member couples the distal end portions with a gap defined therebetween proximally of the pivot member. First and second jaw members extend distally from the shaft members, distally of the pivot member. A lockout bar is movable between an unlocked position, withdrawn from the gap, and a locked position, disposed within the gap. The handles are pivotable between spaced-apart and approximated positions to pivot the jaw members between open and closed positions. The handles are yawable between the approximated position and a yawed position to yaw the jaw members between the closed position and a cutting position. The gap provides clearance to permit yawing such that, when the lockout bar is disposed in the locked position, yawing of the handles is inhibited.

A surgical instrument system comprising a first motor, a second motor, and a third motor is disclosed. The surgical instrument system comprises a first handle comprising a first number of controls, a second handle comprising a second number of controls, and a shaft assembly. The shaft assembly is attachable to the first handle in a first orientation in order to engage one of the motors. The shaft assembly is attachable to the second handle in a second orientation to engage a different motor. The surgical instrument system is configured to perform a different function of an end effector in the first orientation and the second orientation.

An end effector assembly of a surgical device for shallow depth ablation includes first and second jaw members movable between open and closed positions and including hemicylindrical surfaces that cooperate to define a cylindrical cavity in the closed position for capturing tissue therebetween. At least one electrode array includes a plurality of first and second electrode portions disposed on or within at least one of the hemicylindrical surfaces and extending annularly at least partially thereabout. The plurality of first and second electrode portions are configured to be energized with electrosurgical energy at different potentials to thereby conduct electrosurgical energy between adjacent first and second electrode portions and through captured tissue to affect shallow depth ablation of captured tissue in the closed position of the first and second jaw members.

A forceps includes an end effector assembly having first and second jaw members. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes an opposed jaw surface having an electrically-conductive tissue sealing plate disposed thereon. The electrically-conductive tissue sealing plate includes a first portion configured to conduct energy through tissue grasped between the jaw members to create a main tissue seal and a second portion including a plurality of spaced-apart fingers extending from the first portion. The second portion is configured to conduct energy through tissue grasped between the jaw members to create an auxiliary tissue seal extending from the main tissue seal for reducing stress concentrations adjacent the main tissue seal.

Surgical tools are disclosed that include a first handle having a first recess, a second handle having a second recess, a first tip disposed in the first recess and extending distally, and a second tip disposed in the second recess and extending distally. The first tip has a first external surface and a first internal surface. The second tip has a second external surface and a second internal surface. The surgical tool has a first configuration wherein the surgical tool operates as forceps. The surgical tool has a second configuration wherein the surgical tool operates as scissors. The first internal surface can be moved adjacent to the second internal surface to permit rotation of the first tip relative to the first recess and permit rotation of the second tip relative to the second recess. The rotation of the first tip and the second tip transitions the surgical tool between the first configuration and the second configuration.

An end effector assembly of a tissue resection device. The end effector assembly including a first cut guide including a first support surface that extends from a first proximal end portion to a first distal end portion including a first outer distal portion, and a second cut guide located around the first cut guide. The second cut guide having a second support surface that extends from a second proximal end portion to a second distal end portion having a second outer distal portion. The first outer distal portion located distal of the second outer distal portion and the first outer distal portion being located farther laterally from the longitudinal axis than the second outer distal portion. The end effector assembly further including a cutting device located between the first and second cut guides.

A medical connecting device, having a proximal end and a distal end; the medical connecting device includes an insulating layer (3, 123, 222, 322) and a spiral tube (2, 124, 223, 323), the insulating layer (3, 123, 222, 322) covering the outermost layer of the whole device; the spiral tube (2, 124, 223, 323) has a conductive hollow tubular structure; and the spiral tube (2, 124, 223, 323) has a spiral structure, and a pitch of the spiral structure gradually changes in the direction from the proximal end to the distal end. The medical connecting device is able to integrate multiple functions such as electricity conducting, liquid passage, powder spraying, negative pressure suction, sealing, insulation, and support.

An electrically energized medical instrument uses one or more drive cables to both actuate mechanical components of a wrist mechanism or an effector and to electrically energize the effector. Electrical isolation can be achieved using an insulating main tube through which drive cables extend from a backend mechanism to the effector, an insulating end cover that leaves only the desired portions of the effector exposed, and one or more seals to prevent electrically conductive liquid from entering the main tube. Component count and cost may be further reduced using a pair of pulleys that are shared by four drive cables.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.
