The upper jaw includes an upper tooth having an upper proximally facing canted tooth surface and an upper distally facing canted tooth surface. The lower jaw includes a proximal end and a distal end. The lower jaw includes a socket having a lower distally facing canted socket surface and a lower proximally facing socket surface. The upper jaw, the lower jaw, or both are moveable so that the gripping assembly moves between an open position and a gripping position, in the gripping position, a gap is defined between the upper distally facing canted tooth surface and the lower proximally facing socket surface.

Medical forceps with offset teeth

A lever latching system comprising: a housing; a lever having a latch pin fixedly mounted to the lever, the lever being movably mounted to the housing so that the latch pin moves in an arc; and a latch plate movably mounted to the housing for linear movement with respect to the housing, the latch plate comprising a labyrinth for receiving the latch pin.

Endoscopic cutting forceps with jaw clamp lever latching mechanism

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 position. 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 with two-part drive bar

A surgical device comprising: a closure assembly comprising: (a) a movement unit including (i) a bar and (ii) a contact element, wherein the bar, the contact element, or both move in a direction of a prescribed motion; (b) a latch unit comprising: (i) a latch plate including: (1) a hook latch that selectively receives the bar, the latch plate being movable between: (A) a lockable state where the hook latch is engageable by the bar, and (B) an unlockable state where the hook latch is unengageable by the bar; (c) an indicator mechanism that moves into alignment with the prescribed motion of the contact element, the bar, or both when the latch unit is in the unlockable state so that the indicator is contacted by the bar, the contacting element, or both generating an indication.

Forceps including a pre-loaded handle latch

Surgical forceps can include a jaw, a blade, and a tongue. The jaw can include a grip surface defining a slot. The blade can be configured to reciprocate along the slot between an extended position and a retracted position. The tongue can be connected to the jaw where at least a portion of the tongue can be located proximal of the grip surface to guide the blade into the blade slot when the blade moves from the retracted position into the blade slot.

Forceps blade guide

Medical devices, such as forceps including a handpiece having a housing and an inner shaft that extends out of the handpiece along a longitudinal axis to transfer motion to an end effector. The inner shaft being rotatable with respect to the handpiece. An outer shaft that is rotatable with respect to the housing is boated around the inner shaft. The medical device further including an end effector coupled to the inner shaft and the outer shaft. The outer shaft rotationally constrained to the inner shaft at a first longitudinal location and at a second longitudinal location.

Forceps including rotationally locked shafts

A surgical device comprising: a closure assembly including: (a) a movement unit configured to be connected to a movable member, the movement unit including: (i) one or more bars; (ii) one or more bar biasing members in communication with the movement unit and moving the one or more bars; (b) a latch unit configured to be connected to a ground member, the latch unit including: (i) one or more hook latches that selectively receive the one or more bars, and (ii) one or more latch biasing members in communication with the one or more hook latches to selectively move the one or more hook latches; wherein all or a portion of the latch unit is movable relative to the ground member and all or a portion of the movement unit is movable relative to the movable member, and the latch unit and the movement unit are movable relative to each other when the latch unit and the movement unit are in contact.

Forceps including a double biased handle latch

Surgical forceps can include a drive pin an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can define a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a pair of flanges located at a proximal portion of the first jaw, where each flange can include a track receiving the drive pin. The inner tube can be located within the outer tube and can extend along the longitudinal axis. The inner tube can include a pair of arms extending from a distal portion of the inner tube. The drive pin can be securable to the pair of arms. The inner tube can be translatable within the outer tube to drive the drive pin along the tracks to move the second jaw between open and closed positions.

Forceps drive shaft

Surgical tool can include an outer shaft, a guide, an end effector, and a drive shaft. The outer shaft can extend along a longitudinal axis. The guide can be connected to the outer shaft. The end effector can include a first jaw connected to the outer shaft distal of the guide and a second jaw pivotably connected to the outer shaft distal of the guide. The drive shaft can be located within the outer shaft and can extend along the longitudinal axis. The drive shaft can be connected to the end effector and the drive shaft can be engageable with the guide to limit movement of the drive shaft with respect to the outer shaft in a direction not parallel with the guide. The drive shaft can be translatable along the outer shaft to operate the end effector.

Forceps drive shaft control

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.

A forceps including a gripping assembly. The gripping assembly includes an upper jaw and a lower jaw. The upper jaw includes a proximal end and a distal end. The upper jaw includes an upper tooth having an upper proximally facing canted tooth surface and an upper distally facing canted tooth surface. The lower jaw includes a proximal end and a distal end. The lower jaw includes a socket having a lower distally facing canted socket surface and a lower proximally facing socket surface. The upper jaw, the lower jaw, or both are moveable so that the gripping assembly moves between an open position and a gripping position. In the gripping position, a gap is defined between the upper distally facing canted tooth surface and the lower proximally facing socket surface.

The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed position.
