A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

A handle of a device such as an endoscopic surgical appliance is provided with a grip for actuation of an effector mechanism positioned at a distal end. A grip force attenuator within the handle absorbs excessive force after the grip force required to fully actuate the effector mechanism has been reached. The handle includes a first spring which deflects in response to hand grip force up to a predetermined level for actuation of the effector mechanism and a second spring which deflects in response to hand grip force which exceeds the predetermined level without applying such excess force to the first spring.

A surgical sizer sound, comprising an actuatable shaft. The surgical sizer sound also comprises an angled shaft coupled to the actuatable shaft. The surgical sizer sound also comprises a sizer coupler comprising a guide tip and a limit, pivotably coupled to the angled shaft and a sizer, removably coupled to the sizer coupler.

A surgical instrument system includes a surgical fastener applier and a positioning guide. The positioning guide includes an implant guide. The implant guide defines a guide channel configured to receive a portion of an implant to support the implant relative to the end effector to enable the surgical fastener applier to fire one or more fasteners through the implant for securing the implant to tissue.

A method includes obtaining an implant plan, defining a range of motion for a surgical tool based on the implant plan, adjusting, by an actuator and based on the range of motion, a passive joint coupled between the actuator and the surgical tool, and allowing manual movement of the surgical tool through the range of motion via rotation at the passive joint.

Various torque-limiting screwdriver devices, systems, and methods are disclosed. The screwdriver can include a body, a motor that is configured to rotate a screw engaged with the screwdriver, and a processor configured to control operation of the screwdriver. The screwdriver can have torque-limiting functionality, such as by monitoring the amount of torque applied to the screw and reducing or stopping rotation of the screw when certain torque-limiting criteria are met. In some embodiments, the screwdriver can be switched between manual operation by a user, and automated operation by a motor within the screwdriver. In some embodiments, the screwdriver can be attached to a robotic arm.

An ingress-egress apparatus for protection of a surgical work site during removal of a surgical implant therefrom includes an inverted frustum surface having a sidewall defining: a bottom open area at a base portion of the frustum surface sidewall, and an opposing top open area at a top portion of the frustum surface sidewall. The top open area has a larger area than the bottom open area. The apparatus includes an ingress port located at the base portion of the frustum surface sidewall and an egress port located at the base portion of the frustum surface sidewall. During surgical removal of the surgical implant using a surgical burr, the apparatus can be used to irrigate the work site, thereby cooling it and protecting it from damage, and further removing metal implant particles generated during burring.

A surgical tool system including a tool unit and a first battery and control module and a second battery and control module. The tool unit includes a power generating unit and a head for supporting an energy applicator. The first battery and control module is configured to releasably receive the tool unit. The first battery and control module having a first shape so that when the tool unit is attached to the first battery and control module, the tool unit and the first battery and control module have a pencil-grip configuration. The second battery and control module is also configured to releasably receive the tool unit. The second battery and control module having a second shape so that when the tool unit is attached to the second battery and control module, the tool unit and the second battery and control module have a pistol-shaped configuration.

An embodiment in accordance with the present invention provides a remote center of motion robot. The RCM here is a parallelogram bar type RCM mechanism with a novel joint arrangement. The novel joint arrangement facilitates the mounting of the medical instrument and offers improved clearance relative to the patient. Moreover, the robot was built to guide a bone biopsy cannula, needle, or drill. Even though exact interventional values are unknown, it is expected that the forces exerted laterally on the needle-guide are higher than those encountered for slender needle insertion into soft tissue. For this, the RCM has been built with novel structure to enhance stiffness.

An implantable suspension device (1) for fixing an elongated flexible implant (G) or tissue (B) in a desired position, comprising a suspension plate (100) and a single suture element (200) engaging with the suspension plate (100) such that the suture element (200) forms an adjustable suspension loop (300) for connecting said implant (G) or tissue (B) to the suspension plate (100), wherein the single suture element (200) comprises a free first end section (201) and a second end section (202), and wherein the single suture element (200) comprises a stopper (20) arranged on the second end section (202), and wherein the suture element (200) forms a locking loop (40) for pressing the first end section (201) against the suspension plate (100) and thereby locking the first end section (201) of the suture element (200) with respect to the suspension plate (100).
