A medical instrument includes a first hand lever which has a manually actuated grip portion at its proximal end, a work portion for gripping, clamping or cutting an object at its distal end, and, lying between these, a bearing portion on which a bearing element engages in order to permit pivotability about a rotation axis between the first hand lever and a second hand lever, wherein the second hand lever has a grip portion at its proximal end, a work portion at its distal end, and, lying between these, a guide portion on which the bearing element engages, wherein the guide portion of the second hand lever has on one side a recess for receiving the bearing portion of the first hand lever such that two guide protrusions located distally and proximally of the recess at least partially cover the bearing portion in an operating position.

A surgical retractor is disclosed herein. In some embodiments, a surgical retractor includes a body extending from a proximal end to a distal end and having a first portion coupled to a second portion via a hinged connection, wherein the first and second portions are configured to rotate about a body axis; a first radiolucent tip coupled to a distal portion of the first portion; a second radiolucent tip coupled to a distal portion of the second portion; a holder coupled to one of the first or second portions; and a deformable member extending through the holder, wherein the deformable member is configured to be deformed to facilitate fixation of the surgical retractor at a desired location.

A surgical tool includes a drive housing, a shaft extending from the drive housing, an end effector at an end of the shaft and having opposing jaws and a cutting element, and an unclamp lockout mechanism. The unclamp lockout mechanism including a pawl rotatably mounted to the shaft and positioned proximal to a closure yoke operatively coupled to the shaft, the pawl being pivotable between a stowed position, where the pawl is received within an aperture of the shaft, and a deployed position, where the pawl protrudes out of the aperture, and a biasing device that biases the pawl toward the stowed position. When the pawl is in the stowed position, the closure yoke is movable to a proximal position over at least a portion of the pawl to open the opposing jaws. When the pawl is in the deployed position, the closure yoke is prevented from moving to the proximal position.

A needle holder is described, comprising first and second handles. Each handle comprises a finger loop at a proximal end of the handle, an arm fixedly attached to the finger loop, extending toward a distal end of the handle and defining a longitudinal axis, and a jaw fixedly attached to the arm, extending along the longitudinal axis toward the distal end of the handle. The needle holder further includes a sliding pivot joint connecting the first and second handles at a connection point between the arms and the jaws, the sliding pivot joint configured to allow the first and second handles to move rotationally with respect to one another about a rotational axis orthogonal to the longitudinal axis at the connection point, and/or translationally with respect to one another along the longitudinal axis. A method of grasping a needle is also described.

A forceps including a gripping assembly. The gripping assembly includes an upper jaw and a lower jaw. The upper jaw includes a proximal end and a distal end. The upper jaw includes an upper tooth having an upper proximally facing canted tooth surface and an upper distally facing canted tooth surface. The lower jaw includes a proximal end and a distal end. The lower jaw includes a socket having a lower distally facing canted socket surface and a lower proximally facing socket surface. The upper jaw, the lower jaw, or both are moveable so that the gripping assembly moves between an open position and a gripping position, in the gripping position, a gap is defined between the upper distally facing canted tooth surface and the lower proximally facing socket surface.

A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.

A forceps device includes a grasping part, a support that holds the grasping part, a first rotating shaft that turnably supports the support, a base member that holds the first rotating shaft, guide pulleys arranged coaxially with the first rotating shaft, grasping portion wires, a support pulley, and a support wire. The grasping portion wires run over the guide pulleys and the grasping part without other pulleys therebetween, and transmit a first driving force to the grasping part to move the grasping part. The support pulley is provided on the support, and the support wire runs over the support pulley and transmits a second driving force to the support to turn the support about the first rotating shaft.

A surgical clamp for laparoscopic or endoscopic surgeries provides autonomous adjustable pressure and placement with a releasable or integrated remote manipulator. Two jaws move simultaneously with respect to the main body of the clamp to open and close to secure or release tissue and/or organs. In a first embodiment, the instrument is made up of two separable components; a remote manipulator component, and a releasable adjustable pressure clamp component that is linked or separated at an interlocking connection point. The main body of the clamp includes a central tubular port through which a pressure bar passes. An assembly of cam arms connects the push rod to jaws, allowing for symmetrical and simultaneous actuation. A compression spring is positioned around the pressure bar and is secured by an adjustable nut on the threaded end of the pressure bar. Adjustment varies the compressive force of the spring and thereby the gripping force.

An apparatus comprises an electrically power surgical instrument having a handle assembly. The apparatus also comprises a communication device positioned within the handle assembly. The communication device is operable to communicate with at least a portion of the electrically powered surgical instrument. The apparatus further comprises an external device in wireless communication with the communication device. The external device is operable to receive information from the communication device and the external device is operable to provide an output viewable to the user.
