Systems and methods for forming a handle apparatus may include shaping a strip of composite material with a flexible central portion, two grips, and two end portions. The strip may be bent onto itself such that the end portions are fastened together by a fastening device. The handle apparatus may also include a hole disposed in the flexible central portion through which a tool actuator may be passed.

A surgical instrument comprising a lockout is disclosed.

A surgical instrument comprising an end effector is disclosed. The end effector comprises a staple cartridge including a cartridge body comprising an annular array of staple cavities, staples removably stored in the staple cavities, a firing drive configured to eject the staples from the staple cavities, and a cutting member circumscribed by the staple cavities. The end effector further comprises an anvil including a tissue compression surface, forming surfaces configured to deform the staples and a tissue block. The anvil is movable toward the cartridge body to compress tissue between the cartridge body and the tissue block and the cutting member is configured to incise the tissue and the tissue block during a cutting stroke of the cutting member.

A laparoscopic scissor instrument can include a scissor assembly pivotally coupled to an elongate shaft. The scissor assembly can be formed of scissor blades having pivot posts thereon. The pivot posts can engage apertures on the elongate shaft, thus eliminating the need for a through-pinned pivot connection of the scissor blades. The scissor blades can also include actuation posts thereon. An actuation mechanism can include a slot to engage the actuation posts and open or close the blades of the scissor assembly. The scissor assemblies described herein can have a relatively low operational height such that they do not extend beyond a diameter of the elongate shaft during opening and closing of the scissor assembly.

A surgical instrument has an end-effector located on the end of a rotatable shaft, the shaft projecting from a handle. A thumbwheel is provided at the proximal end of the handle, which controls the rotation of the shaft, and hence the rotational orientation of the end-effector. The end-effector is capable of grasping, cutting, and sealing and/or coagulating tissue, and one of the operations is controlled by a switch located on the upper surface of the proximal end of the handle. The switch is oriented on the handle to be generally above the thumbwheel, in a relative position to the thumbwheel so that both the thumbwheel and the switch may be activated by the user's thumb, without the user having to alter his grip on the handle. In one embodiment of the invention the switch is therefore vertically oriented above the thumbwheel.

An anchor assembly can include at least one anchor member, such as a pair of anchor members that are configured to be implanted in a target anatomical location in a first configuration, and can subsequently be actuated to an expanded configuration that secures the anchor members in the target anatomy. The anchor assembly can further include a connector member configured as a stitch lock that attaches the pair of anchor members together across a gap so as to approximate the anatomical defect.

Disclosed is an instrument assembly usable in a procedure. The instrument includes a connection for a working portion and to a tool handle. A tracking device or assembly may be associated with the instrument for determining a position of the instrument.

Provided are an end tool of a surgical instrument and a method of manufacturing the same, and more particularly, an end tool of a surgical instrument that may be manually operated to be used in laparoscopic surgery or other various surgery and a method of manufacturing the end tool, wherein a load applied to a pin (rotary shaft) and the pulley is appropriately distributed such that the pulley may be sufficiently rotated and at the same time, an overall durability may be improved.

A medical sliding-shaft instrument having a first handle arm, a second handle arm pivotably mounted to the first handle arm, a shaft connected to the first handle arm and a slider coupleable to the second handle arm and axially displaceable on the shaft. The slider is removable from the shaft and is guided along a sliding path. A cross-pin couples the second handle arm to the slider and is received in a slot defined by first and second legs of the second handle arm. The first leg is a resilient tongue moveable transversely to a longitudinal axis of the first leg and outwardly away from the second leg. The second handle arm is positioned so that the cross pin lies in the slot. The cross pin is covered and held back by the first leg and is released by applying a force and displacing the end of the first leg.

A deployment mechanism for selectively deploying and retracting an energizable member and/an insulative member relative to an end effector assembly of a surgical instrument includes one or more actuators, a clutch assembly, and a drive assembly. The clutch assembly is configured to couple to the actuator(s) to provide rotational motion in the first direction in response to such rotation of the actuator(s) and to decouple from the actuator(s) in response to rotation thereof in the second direction. The drive assembly is operably coupled to the clutch assembly and is configured to convert the rotational motion provided by the clutch assembly into longitudinal motion to translate the energizable member and/or insulative member from a storage position to a deployed position and to translate the energizable member and/or the insulative member from the deployed position back to the storage position.
