Endoscopic stitching device having angled suture needle
11751866 · 2023-09-12 · ·

A surgical stitching device includes a suture needle configured to reliably pass through a typically thick scarred tissue present along, e.g., an edge of midline hernias. The surgical stitching device includes first and second jaws. The suture needle is selectively supported on the first or second jaws at, e.g., an acute, angle with respect to a longitudinal axis defined by the corresponding first or second jaw. The suture needle may be selectively secured with the first or second jaw by first and second needle receiving blades configured for reciprocating axial displacement. A suture is connected to the suture needle to perform suturing of tissue.

Device for atrial appendage exclusion

A surgical applicator for a fastener, the surgical applicator comprising: a handle; a trigger movable relative to the handle between an initial position, an actuated position, and an intermediate position between the initial position and the actuated position; and a lockout mechanism movable relative to the trigger between a locked position and an unlocked position, the lockout mechanism operatively arranged to: lock the trigger in the intermediate position when the trigger is moved from the initial position toward the actuated position; and permit movement of the trigger from the intermediate position toward the initial position or the actuated position when the lockout mechanism is moved from the locked position to the unlocked position.

Stapling assembly comprising a retraction drive

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.

CLEANING SYSTEM FOR IMAGING DEVICES

An apparatus includes a tubular structure having a proximal end, a distal end, and a body extending between the proximal and distal ends, wherein the body includes a lumen for housing at least a part of an imaging device, and a fluid delivery channel that is fixed in position relative to the body, and an opening that is in fluid communication with the fluid delivery channel, wherein the fluid delivery channel has a first portion, and a second portion that forms an angle with an axis of the first portion.

METHOD FOR OPERATING A SURGICAL STAPLING SYSTEM

A surgical instrument system is disclosed which comprises a distal end and a staple cartridge assembly comprising staples removably stored therein. The instrument system further comprises a firing drive including an electric motor and a firing member operably couplable with the electric motor. The electric motor is operable to advance the firing member toward the distal end during a staple firing stroke to eject the staples from the staple cartridge. The electric motor is operable to retract the firing member away from the distal end during a retraction stroke. The surgical instrument system further comprises a manually-operated bailout mechanism operable to perform the retraction stroke in lieu of the electric motor, a controller, and a display in communication with the controller. The controller is configured to display the progress of the retraction stroke when the firing member is being manually retracted by the bailout mechanism.

Surgical stapler having a powered handle

A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.

Powered surgical stapler

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.

Cleaning system for imaging devices

An apparatus includes a tubular structure having a proximal end, a distal end, and a body extending between the proximal and distal ends, wherein the body includes a lumen for housing at least a part of an imaging device, and a fluid delivery channel that is fixed in position relative to the body, and an opening that is in fluid communication with the fluid delivery channel, wherein the fluid delivery channel has a first portion, and a second portion that forms an angle with an axis of the first portion.

Electrosurgical devices

In various embodiments, a surgical instrument is disclosed. The surgical instrument comprises a handle assembly having a closure trigger, a closure actuator coupled to the closure trigger at a first pivot, and a closure spring. The closure actuator moves proximally on a longitudinal axis in response to actuation of the closure trigger. The closure spring applies a force vector to the closure spring tangential to the longitudinal axis. A shaft assembly is coupled to the handle assembly. An end effector is coupled to a distal end of the shaft assembly. The end effector comprises a jaw assembly comprising a first jaw member and a second jaw member. The first jaw member is pivotally moveable with respect to the second jaw member. At least one of the first and second jaw members are operatively coupled to the closure actuator.
