20230071969 · 2023-03-09 ·

A surgical instrument includes an end effector, and a shaft assembly. The end effector includes an ultrasonic blade, a rotating body, and a clamp arm movable between an open and a closed position. The shaft assembly extends along an axis and includes clamp arm clocking assembly and a clamp arm pivot assembly. The clamp arm clocking assembly can drive the rotating body and the clamp arm between a first clocked position and a second clocked position. The clamp arm pivot assembly includes an actuator body defining a track, where the actuator body can actuate to drive the clamp arm between the open position and the closed position while the actuator body is in a rotational position relative to the ultrasonic blade. The track houses a portion of the clamp arm in the first clocked position and the second clocked position while the actuator body is in the rotational position.

SURGICAL INSTRUMENTS HAVING A MOVABLE BLADE MEMBER FOR TREATING TISSUE

A surgical instrument for treating tissue includes an articulating elongated shaft (14), a drive shaft (124) extending through the elongated shaft and configured to rotate about a longitudinal axis defined by the drive shaft, and an end effector assembly 100) coupled to a distal end portion of the elongated shaft. The end effector assembly includes a jaw member (110) and a blade member (112) configured to oscillate in response to a rotation of the drive shaft (124) to treat tissue disposed between the jaw member and the blade member.

Stapling assembly comprising a shiftable 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.

Surgical instruments with torsion spine drive arrangements

Surgical instruments with articulatable surgical end effectors and rotary driven flexible drive members.

SURGICAL END EFFECTORS

An end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

TREATMENT TOOL AND METHOD OF ADJUSTING TREATMENT TOOL

A treatment tool includes: a first grasper; a second grasper that is rotatably provided with respect to the first grasper, the second grasper being configured to grasp a target region together with the first grasper by approaching the first grasper; a shaft configured to rotate the second grasper with respect to the first grasper; and an adjustment mechanism configured to adjust a trajectory along which the second grasper passes when the second grasper rotates about the shaft and approaches the first grasper, the adjustment mechanism including a protrusion provided according to a predicted length to be required due to variations in components.

Push-to-close actuated dual action spaced pivot assembly for surgical instrument jaws, blades, and forceps

A push-to-close actuated, dual-action, spaced pivot, assembly for jaws, blades, and forceps devices. The assembly is structured for use with a push rod, cable, or solid wire forceps actuator surgical instrument. A jaw receiving body of the assembly is adapted to receive a wide variety of types of jaws performing different surgical functions. Two separate moving jaws each pivot about a separate spaced pivot pin, on opposite sides of the jaw body centerline. A handle with a pushing actuating rod provides a pushing motion to a drive rod, cable, or solid wire within a cable sheath to push a connected yoke in the assembly to push against the jaws to close the jaws together.
