A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

Surgical Stapling Apparatus

An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.

Vessel sealer and divider

A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of the cartridge (10) and the anvil (22). The cartridge (10) can be moved towards the anvil (22) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge (10) and is positioned such that there is at least one row of staples on at least one side of the knife.

Newness and distinctiveness is claimed in the features of ornamentation as shown inside the broken line circle in the accompanying representation.

Display screen or portion thereof with graphical user interface

A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Surgical stapling instrument with an articulatable end effector

In a manipulator, an actuator block contains motors and rotary shafts extending from the motors. A working unit of the manipulator contains a connecting portion, attachable to and detachable from the actuator block. The connecting portion has pulleys connectable to ends of the rotary shafts, and has a locking plate movable by alignment pins. The locking plate has slits, which are engaged with plate-shaped portions formed on the upper ends of the pulleys. A coil spring is placed between the locking plate and a top plate.

Manipulator for medical use

A medical manipulator (10) includes an operation command unit (14) having motors and a working unit (16) detachably mounted on the operation command unit (14) The operation command unit (14) includes a grip handle (26) for being gripped by a human hand, and a trigger lever (32) movable toward and away from the grip handle (26) The trigger lever (32) comprises a pulling member (101) which can be pulled toward the grip handle (26) by a finger held against the pulling member (101), and a pushing member (102) which can be pushed away from the grip handle (26) by the finger held against the pushing member (102), the pushing member (102) being disposed in facing relation to the pulling member (101) The pushing member (102) has a hemispherical cavity (104) defined in a surface thereof which faces the pulling member (101)

Operating mechanism, medical manipulator, and surgical robot system

A manipulator includes a composite input unit that is manually operable by the fingers, a connector shaft extending from an operating unit, and a working unit mounted on the distal end of the connector shaft. The working unit comprises a rolling mechanism, a tilting mechanism, and an opening and closing mechanism. The composite input unit includes a shuttle ring for actuating the rolling mechanism. The manipulator also includes a gripper for gripping a curved needle. The gripper is placed near a DVC, whereupon the rolling mechanism is actuated to roll the gripper and to pierce a living body with the curved needle, until the point of the curved needle projects outside of the living body.

Intracoelomic suturing and ligating method

PROBLEM TO BE SOLVED: To prevent power distribution to an electricity action part at the distal end when a working part is detached from an actuator block. SOLUTION: The medical manipulator 10 includes the actuator block 30 with motors 40a-40c; a connection part 15 with pulleys 50a-50c, detachable from the actuator block 30 to be connected the axes of rotation of the motors 40a-40c; the working part 16 including a distal end operating part 12 operatively connected with the pulleys 50a-50c; an electrode 400 disposed in the connection part 15 and to which a power feed line 404 for feeding electric power to the distal end operating part 12 is connected; and a switch part 426 for electrically opening/closing a connection shaft 48 and the electrode 400. The switch part 426 is operated interlocking with the attaching/detaching of the actuator block 30 to/from the working part 16. The switch part 426 is conductive when the actuator block 30 is connected with the working part 16, and is inconductive when the actuator block 30 is not connected with the working part 16.
