The invention relates to a medical instrument having a hollow shaft, whose proximal end can be connected to an operating unit and having a tool tip arranged at the distal end of the shaft having a tool arranged at the distal end of the tool tip, wherein the tool has two jaw parts , which can be pivoted relative to one another and wherein the jaw parts are pivoted via actuating elements, which are mounted so as to be axially displaceable in the shaft and which can be actuated on the proximal side via the operating unit and wherein the tool tip can be pivoted via a joint mechanism relative to the longitudinal axis of the shaft.

In order to provide a medical instrument, which ensures a uniform transmission of tensile and compressive forces even via the pivot region to the tool tip, it is proposed according to the invention that the pivotable jaw parts are each coupled via an articulated drive element to the distal end of an actuating element mounted so as to be axially displaceable in the shaft such that the articulated drive element spans the region of the joint mechanism between the distal end of the shaft and the proximal end of the tool tip.

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

Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue.

An end effector assembly includes first and second jaw members movable between an open and closed position to grasp tissue therebetween. First and second proximal flanges extending proximally from the second jaw member and defining a space therebetween, a proximal flange extend proximally from a proximal portion of the first jaw member and define a cam slot. A cam driver operably is coupled to the proximal flange of the first jaw member to define a space between the cam driver and the proximal flange of the first jaw member. A cam bar is disposed within the space defined between the cam driver and the proximal flange of the first jaw member. The cam bar includes a cam pin configured to move within a cam slot of the cam driver to move the first jaw member relative to the second jaw member between the open position and the closed position.

A staple cartridge for use with a surgical instrument is disclosed. The staple cartridge comprises an elongate slot, a deck surface, and a row of staple cavities. Each staple cavity comprises proximal and distal ends. The distal end is closer to the elongate slot than the proximal end. A firing member is configured to drive the staple drivers from an unfired position to a fired position. The distal end of the staple cavity is aligned with a first end of a staple driver, and the proximal end of the staple cavity is aligned with a second end of the staple driver. The first end of the staple driver extends a first distance above the deck surface and the second end of the staple driver extends a second distance above the deck surface when the staple driver is in the fired position. The first distance is different than the second distance.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

An end effector for use and connection to a robot arm of a robotic surgical system, wherein the end effector is controlled and/or articulated by at least one cable extending from a respective motor of a control device of the robot surgical system, is provided. The end effector includes a wrist assembly, and a jaw assembly. The jaw assembly includes a cam pulley rotatably supported on at least one support plate of the jaw assembly, wherein the cam pulley is operatively connected to a proximal end of each of the jaws of the jaw assembly such that rotation of the cam pulley results in one of an opening and closing of the jaw assembly.

A surgical instrument includes a jaw tool with two branches that can be closed for grasping tissue. In order to transmit the closing force to at least one branch, the branch is coupled with a preferably manually actuatable pull/push element, and, for coupling, an actuating pin that supports a sleeve interacts via the sleeve with a coupling track, in which case the sleeve rolls off the coupling track. In this manner, any deformation, abrasion or burr formation on the coupling track is prevented to such an extent that, even after numerous closing movements of the branches, the branches can still be actuated unimpaired by any wear of the coupling track and the actuating pin, respectively.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

A surgical instrument for use with a robotic surgical system includes a knife blade configured to cut tissue and a knife tube coupled to the knife blade and configured to translate to move the knife blade for cutting tissue. The surgical instrument also includes a gearbox assembly coupleable to a robotic surgical system and configured to translate the knife tube to move the knife blade for cutting tissue and a knife blade lock operably coupled to the gearbox assembly. The knife blade lock is movable from a locked position wherein the knife blade lock prevents translation of the knife tube to an unlocked position in response to coupling of the gearbox assembly to the robotic surgical system wherein the knife tube is permitted to translate to move the knife blade for cutting tissue.
