Forceps jaw flanges
Forceps can include an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can extend along a longitudinal axis and can include a pair of outer arms extending from a distal portion of the outer tube. The first jaw can be pivotably connected to the outer tube and the first jaw can include a first flange and a second flange each located at a proximal portion of the first jaw. The first flange and the second flange can each include a proximal portion extending outward of the outer tube when the jaws are in an open position. The proximal portions can be shaped to limit extension of the proximal portions laterally beyond the outer arms.
Forceps having actuator splay control
Forceps with improved actuation include a housing and a body that is longitudinally slidable relative to the housing. The body having a peripheral flange extending outward towards the housing. A trigger includes an actuation surface configured to receive a force input from a user. The trigger further including at least one arm configured to transfer the received force input to the body. To inhibit lateral splaying of the at least one arm when the trigger is actuated, the housing includes a first control surface, such as a rib proximate the arm.
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.
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.
Forceps with intentionally misaligned pin
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.
Minimally invasive methods for multi-fluid tissue ablation
Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.
Forceps guide plug
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.
SURGICAL INSTRUMENT WITH MULTI-FUNCTION BUTTON
An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes an activation member that is operable to move in a first direction to select a mode of operation. The shaft assembly extends distally from the body and includes an acoustic waveguide. The end effector includes an ultrasonic blade that is in acoustic communication with the acoustic waveguide. The activation member is operable to move in a second direction to activate the end effector in a mode of operation selected by movement of the activation member in the first direction.
Forceps blade control
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.
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.
