An end effector assembly for an optical surgical instrument includes a jaw member and a plurality of optical elements positioned within a cavity of the jaw member. The jaw member has a tissue contacting surface. The jaw member has a proximal portion that is configured to secure a fiber optic cable thereto such that a distal end of the fiber optical cable extends into the cavity. The plurality of optical elements are arranged in a staircase-like manner that rises towards the tissue contacting surface as the plurality of optical elements extends distally within the cavity. The plurality of optical elements is configured to direct a beam of light exiting the fiber optic cable towards the tissue contacting surface.

A surgical instrument configured for both grasping and cutting operations has a shaft with a push rod extending through it. An end effector on the shaft has a grasping jaw, a cutting jaw, and an intermediate jaw. The grasping jaw forms a grasping device with the intermediate jaw, and the cutting jaw forming a cutting device with the intermediate member. A segment of the shaft proximal to the end effector is axially rotatable between a first position, in which the push rod can advance through the segment to actuate the cutting device, and a second position in which the push rod can advance through the segment to actuate the grasping device.

Clamping forceps device includes two clamps in pivotal connection to one another and each having an operator end for being operated by a health care provider. The device also includes an extension extending aft of the operator end of each clamp, the extension forming a space therebetween sized to form a disconnecting wedge mechanism for separating a tube from a patient tube connector. Each extension defines a ramped surface increasing in thickness moving from an extension tip towards the operator end.

Techniques for grasp adjustment include a computer-assisted device comprising a repositionable structure configured to support an end effector and one or more processors. The one or more processors are configured to receive one or more images of the end effector; determine, based on the one or more images, at least one of a first length between a proximal end of jaws of the end effector and a proximal end of a grasping zone, a second length corresponding to a length of the grasping zone, a third length between a distal end of the grasping zone and the distal end of the at least one jaw; or an angle between the jaws of the end effector; and adjust a force or a torque magnitude limit used to limit actuation of the end effector based on at least one of the first length, the second length, the third length, or the angle.

A surgical extractor including a second arm having a proximal end and a distal end, and a first arm having a proximal end for attachment to an extraction device. The first arm additionally has a distal end for attachment to a first modular jaw. The first arm further includes a transverse opening having fastener structure configured to releasably retain an extraction impactor or an extraction device connector. The surgical extractor additionally includes a link pivotably connected to the first and second arms, the link having a distal end for attachment to a second modular jaw.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A vibration transmission member includes: a main body portion configured to transmit ultrasound vibration; a treatment portion that is provided at a distal end of the main body portion, the treatment portion being configured to apply ultrasound vibration to a living tissue; a coating portion that is made of an electrically insulating material containing a first resin, the coating portion being configured to cover a part of a surface of the treatment portion; and a mold portion that is made of an electrically insulating material containing a second resin different from the first resin, and that is fused to at least a part of the coating portion.

A surgical instrument comprising an end effector, an articulation system, a firing system, a closure system, a lock system, and a control unit is disclosed. The end effector comprises a pair of movable jaws. The articulation system articulates the end effector when the articulation system is in an active state. The closure system is actuatable to move the pair of jaws. The lock system prevents the closure system from actuating when the lock system is in a locked state. The control unit controls the supply of power from a power source to the articulation system, the firing system, and the lock system. The control unit transitions the lock system to the locked state and prevents the supply of power from the power source to the firing system when the articulation system is in the active state.
