In one aspect, a surgical retractor having sliders configured to have tissue engaging members connected thereto and slider drives including operating members. The operating members are rotatable to cause the slider drives to shift the sliders relative to one another. The surgical retractor includes a coupler having a coupling configuration wherein the coupler connects the slider drives and rotation of one of the operating members causes movement of the sliders. The coupler also has a decoupling configuration wherein the coupler disconnects the slider drives and rotation of the one operating member causes movement of fewer sliders than the sliders that are moved with the coupler in the coupling configuration. The retractor has an actuator connected to the coupler and movable between a dependent slider movement position and an independent slider movement position to shift the coupler between the coupling configuration and the decoupling configuration.

An apparatus for operating on tissue includes a body assembly, a shaft, an acoustic waveguide, and an end effector. The end effector includes an ultrasonic blade, a clamp arm, and a blade guard. The ultrasonic blade is in acoustic communication with the waveguide. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The clamp arm has a first tine. The blade guard extends from the shaft. The blade guard has a longitudinally extending arm defining a concave pathway and a second tine located distal to the longitudinally extending arm. The ultrasonic blade is partially housed within the concave pathway. The first tine and the second tine are configured to grasp tissue when the clamp arm pivots toward the ultrasonic blade.

A medical device for performing a hysterectomy is provided. The medical device has a tissue incision assembly that includes a first cup nested within a second cup. The tissue incision assembly also includes a spacer assembly between the first cup and the second cup in order to maintain a spacing between the first and second cups. The tissue incision assembly also has a cutting implement that has a portion extending between, and movable with respect to, the first and second cups. The cutting implement can provide a circular cut guided via the spacing between the first and second cups.

A surgical stapling system for treating tissue of a patient is disclosed. The surgical stapling system comprises an end effector, a firing member, a motor, a RF transceiver configured to transmit RF signals, and a sensing array. The end effector comprises an elongate channel, an anvil rotatable relative to the elongate channel from an open position toward a closed position, and a staple cartridge removably positioned in the elongate channel. The staple cartridge comprises a plurality of staples removably stored therein. The firing member is movable between an unfired position and a fired position. The staples are deployed from the staple cartridge based on the firing member being moved toward the fired position. The motor is configured to drive the firing member toward the fired position. The sensing array is configured to sense compression of the tissue, properties of the tissue, and a presence of metallic elements within the tissue.

A surgical drain including an introducer having a central axis, a proximal end, and a distal end. The proximal end disposed along the central axis and configured to couple to a drain. The distal end having a blunt distal tip and the introducer at least partially tapering from the proximal end to the distal end, wherein the introducer has a length of 30 cm or greater.

Integratable treatment devices, assemblies including a treatment device, at least one anchor, and a tether coupled thereto, and various methods and devices for inserting such devices and assemblies are disclosed herein. The treatment devices can be made of an integratable material that is not fully bioresorbable but promotes native tissue growth in and around the material. Certain methods involve first inserting at least one anchor and then advancing a treatment device via a tether coupled to the at least one anchor. Further various insertion devices that can be used to implant any of the treatment devices herein using any of the methods herein are disclosed.

The present invention relates to a method for registration of 2D images of a region of interest of a patient, wherein the images are acquired using an X-ray imaging system and an imaging kit (1) comprising abase (2) and a registration phantom (3), wherein the method comprises the following steps: receiving a first (respectively second) set of 2D X-ray images of at least one first (respectively second) portion of a region of interest, said first and second sets of images comprising each at least two 2D images containing each at least one detectable radiopaque fiducial of the registration phantom (3); registering the first (respectively second) set of images in the coordinate system of the registration phantom in the first (respectively second) phantom fixation position; registering the first and second sets of 2D images in the coordinate system of the base.

A surgical retractor tool includes a handle and a blade extending transversely from a front end of the handle. The blade includes a proximal portion and a distal portion with respective proximal and distal tissue engaging surfaces. The distal tissue engaging surface may be skewed relative to the proximal tissue engaging surface such that the handle may be angled relative to a direction of retraction when the surgical retractor tool is used. A distal tip of the retractor may include a curved tongue that may be curved in a direction opposite the direction of retraction.

A medical instrument with a distal and a proximal end. A first tool element and a second tool element are arranged or formed on the distal end so as to be movable relative to one another. The tool elements define a tool element direction of extent from proximal to distal. The first tool element defines a first tool element face and the second tool element defines a second tool element face. The first tool element face and the second tool element face face toward one another. The tool elements define in the region of their tool element faces a width. The widths extend in a direction transverse to the tool element direction of extent and transverse to a surface normal of the first tool element face and/or the second tool element face.

An offset guide that places a surgical tool through a bone of a surgical joint. The offset guide may hold the surgical joint in a reduced configuration at a first location along the bone; the first location preferred for engaging the bone. The offset guide may engage the bone with a hook that engages two opposing sides of the bone to center the surgical tool through the bone. The offset guide may guide placement of a surgical tool through the bone center at a second location along the bone, the second location offset from the first location. The second location may be a preferable location for receiving the surgical tool therethrough. The surgical tool may include both a drill and an implant insertion tool. The implant insertion tool may place an implant at the second location, while the offset guide holds the surgical joint.
