A forceps includes first and second shafts, each having a jaw member disposed at a distal end thereof. At least one jaw member is moveable from an open to a closed position for grasping tissue therebetween. At least one jaw member is configured for reciprocation of a blade therethrough. A trigger assembly includes a trigger and at least one linkage coupled to the trigger and to the blade such that rotation of the trigger translates the blade between the retracted and the extended position. An interference member moveable between a locked position and an unlocked position is also provided. The interference member is configured to engage the linkage(s) when in the locked position to inhibit translation of the blade from the retracted to the extended position.

A forceps device includes forceps deployable through a needle. In one embodiment, both jaws of the forceps are movable with respect to each other, and their movement is controlled by a box slider. In another embodiment, one jaw is fixed and the other jaw is movable. In one embodiment the jaws include teeth that increase in length from the proximal end of the jaws to the distal end of the jaws. In a further embodiment, suction may be achieved through the needle when the forceps are removed.

A compact medical treatment tool having an end portion, used for surgery, and a surgical system having such a medical treatment tool are provided. A medical treatment tool includes an end effector, a wrist member, a shaft, a first pulley, and a second pulley. A first pulley portion included in the end effector is rotatably mounted on the wrist member via a first connection, and is located closer to a first end of the first connection. The first pulley is mounted on the wrist member. A rotational axis of the first pulley intersects with a plane defined by a shaft axis and a first axis that is defined by the first connection. The rotational axis of the first pulley is located closer to a second end of the first connection, opposite to the first end of the first connection, than a groove of the first pulley portion.

The invention provides a pair of dual-purpose forceps, comprising a first forceps body and a second forceps body. When the first forceps body is connected with the second forceps body by means of a first pressurizing connecting member and a second pressurizing connecting member, a first handheld member and a second handheld member move towards each other, and a first pressurizing functional member and a second pressurizing functional member also move towards each other to complete pressurizing; when the first forceps body is connected with the second forceps body by means of a first opening connecting member and a second opening connecting member, the first handheld member and the second handheld member move towards each other, and a first opening function member and a second opening function portion face away from each other to complete opening. The dual-purpose forceps is simple in structure and is operated conveniently so that the double-purpose forceps can switch freely between opening and pressurizing functions conveniently and quickly.

Disclosed is an instrument assembly for a selected procedure. The procedure may include a dissection and neural monitoring. The instrument may be insulated to allow for a selected and precise electrical conductive path.

Conventional vasectomy techniques suffer from a number of potential complications, including, for example, a substantial risk for the development of hematomas, and swelling, and post-surgical pain, a potential for spontaneous duct reconnection and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The vasectomy methods of the present invention reduce and/or minimize contact with sensory nerves located on the distal side of the vas deferens, particularly the distal region of the outer vas deferens sheath, so as to minimize nerve damage and the post-surgical pain associated therewith. In addition, the methods of the present invention overcome the disadvantages and deficiencies of the prior art, resulting in a rapid, reliable, minimally-invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

A surgical instrument includes a body, an ultrasonic blade, a clamp arm, and a resilient member. The body includes an electrical conductor and defines a longitudinal axis. The clamp arm is pivotably coupled with the body at a pivot assembly. The clamp arm is operable to compress tissue against the ultrasonic blade. The clamp arm includes an electrode operable to apply RF energy to tissue, wherein the clamp arm is configured to be loaded onto and removed from the body at the pivot assembly along a path that is transverse to the longitudinal axis defined by the body. The resilient member is located within the pivot assembly. The resilient member is configured to provide electrical continuity between the electrode of the clamp arm and the electrical conductor of the body.

A surgical instrument includes a rotatable electrical coupling assembly having a first part and a second part that electrically couple and rotate relative to each other. The second part is carried by and rotates with a tube collar coupled to a transducer. A portion of the transducer is inserted through an aperture of the second part, but does not contact the second part. The first part of the assembly may electrically couple to the second part via pogo pins, brush contacts, or ball bearings. Alternatively, the first part may comprise conductive channels formed in the casing. The second part may comprise a rotatable drum with a conductive trace. In some versions, one or more components may comprise MID components. In another version, the rotatable electrical coupling assembly comprises a rotatable PC board and brush contact. Further still, a circuit board may be provided with the transducer inside a transducer casing.

A forceps includes first and second shafts, each having a jaw member disposed at a distal end thereof. At least one jaw member is moveable from an open to a closed position for grasping tissue therebetween. At least one jaw member is configured for reciprocation of a blade therethrough. A trigger assembly includes a trigger and at least one linkage coupled to the trigger and to the blade such that rotation of the trigger translates the blade between the retracted and the extended position. An interference member moveable between a locked position and an unlocked position is also provided. The interference member is configured to engage the linkage(s) when in the locked position to inhibit translation of the blade from the retracted to the extended position.

A device including forceps having first and second working arms, a blade, and an arm securing mechanism having an electromagnetic latch. Distal ends of the first and second arms are biased toward each other by a first force when the electromagnetic latch is energized. The device is switchable between a first configuration where the distal ends of the arms are biased away from each other and the blade is proximal to the distal ends of the arms; a second configuration where the distal ends of the arms are biased toward each other by the first force and the blade is proximal to the distal ends of the arms; and a third configuration where the distal ends of the arms are biased toward each other by the first force and the blade is substantially flush with or extends beyond the distal ends of the arms.
