FORCEPS ACTUATION SYSTEMS

Forceps including a housing, a first body, a second body and a drive shaft. The first body has a passageway extending therethrough. The drive shaft extending through the passageway and connected to the first body such that the first body and the drive shaft are slidable with respect to the housing to drive jaws located at a distal portion of the drive shaft between an open position and a closed position. The second body having a second passageway. The drive shaft extending through the second passageway such that the second body is guided by the drive shaft and is slidable relative to the first body and the drive shaft to displace a blade shaft between a retracted position and an extended position.

A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.

A surgical tool can include an outer tube, an end effector, an inner tube, and a distal plug. The outer tube can extend along a longitudinal axis and the outer tube can include a pair of outer arms. The end effector can be connected to the outer arms. The inner tube can be located within the outer tube and can extend along the longitudinal axis. The inner tube can be connected to the end effector and the inner tube can be translatable along the outer tube to operate the end effector. The distal plug can be securable to the outer tube between the outer arms proximal of the end effector. The distal plug can include a wire routing bore extending therethrough.

Advanced leverage instrument

An instrument including a first arm and a second arm. The first arm includes a first jaw including a first distal end. The second arm includes a second jaw including a second distal end. One of the first jaw and the second jaw includes a first protrusion. When the instrument is moved into a closed configuration, the first distal end and the second distal end make contact, which occurs after the first protrusion and the opposing jaw make contact.

A surgical tool can include a shaft, a pin, an end effector, and a translating member. The shaft can define a longitudinal axis. The pin can be located at a distal portion of the shaft. The end effector can be connected to the shaft. The translating member can be positioned laterally inward of the shaft. The translating member can include a track and the pin can extend into the track to limit translation of the translating member along the longitudinal axis with respect to the end effector.

Vascular punch

The invention discloses a novel vascular punch employing compressive normal force for tissue separation from a targeted vessel. This invention is particularly designed for making a large round hole without massive bleeding in vascular surgery. A clean, non-frayed hole-making guided by the normal force cutting principle is realized using a site-biting punch mechanism. The side-biting vascular punch comprises a U-shaped razor blade cutter, a backstop for receiving the cutter, and a linkage mechanism, forming an aligned line of contact for normal compression force generation and thereby severing tissue out of the targeted vessel.

Forceps with two-part drive bar

A forceps having a first jaw and a second jaw, where at least one of the first and second jaws is capable of moving between an open position and a closed positions. The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.

SURGICAL INSTRUMENT

A surgical instrument is provided that may be used to occlude organic body parts during surgery. The surgical instrument is generally composed of an actuating device, a gripping device, and a joint system. The surgical instrument may be rotated about the joint system such that the actuating device can be pivoted out of the operating field during use. The actuating device can be used to transmit a pivoting movement and an actuating movement that operates the gripping device. The gripping device is constructed of gripping elements that can occlude organic body parts. The surgical instrument also includes a locking system that can prevent the rotation of the surgical instrument about the joint system. The locking system may also prevent the operation of the actuating device when the surgical instrument is pivoted about the joint system.
