Prosthetic foot

A prosthetic foot having an adjustable height heel includes a frame portion with an ankle link pivotally supported on the frame portion at a first pivot axis. A detent rod is pivotally connected to the ankle at a second pivot axis, and a detent member is pivotally affixed to the frame portion at a third pivot axis. The detent member is selectively operable to receive and releasably retain a length of the detent rod therein so that the length of the detent rod extending between the second and third pivot axes may be selectably adjusted. When the length of the rod is so adjusted, the angular relationship of the frame portion and the ankle link is changed thereby changing the heel height of the foot. The detent mechanism may be activated by various means including fluidic means, mechanical means, electromechanical means, and the like.

An ankle block for a leg prosthesis comprising an insert having a body with an upper mounting surface and a bottom interface surface opposite from the upper mounting surface. The insert body defines a central coaxial hole therethrough. An over mold is formed about an exterior of the body and extends upwardly therefrom defining a central cavity above the insert and above the upper mounting surface.

Exoskeletal leg prosthesis and method for alignment

A prosthetic foot gasket for sealing between a foot shell covering a foot portion of an endoskeletal prosthetic leg and a leg portion thereof comprises a peripheral body having an upper surface and further defining a central opening therethrough. A lip extends from a bottom of the body and in combination with the body defines a groove therearound for receiving a top portion of the foot shell. A seal is affixed to an upper surface of the body for sealing engagement with the leg portion of the prosthetic leg.

A prosthetic foot assembly includes an ankle member, a heel member pivotally connected to the ankle member, an elongate metatarsal-toe member having a rear portion underlying a forward portion of the heel member and projecting forwardly from the heel member. The metatarsal-toe member is pivotally connected to the heel member. A first compressible element is engaged between a portion of the ankle member and a portion of the heel member and a second compressible element having first and second substantially circular bearing surfaces engaged between a portion of the heel member and a portion of the metatarsal-toe member to resist upward pivotal movement of a forward end of the metatarsal-toe member relative to the heel member. A portion of the compressible element spaced apart from one of the bearing surfaces has a smaller diameter than the diameter of at least one of the first and second bearing surfaces. Also disclosed is a prosthetic foot assembly incorporating noise abatement features including surface treatments and modified compressible elements or pads.

The present invention is footwear for use by an able-bodied person to test and appreciate the functions of a prosthetic foot. The footwear includes an upper for attachment to a user's foot and a mounting plate attached to the inside sole of the footwear. An adapter is mounted to the mounting plate for receipt of the foot prosthesis. The adapter allows for adjustment of the prosthesis with respect to the footwear.

A prosthetic foot assembly, said assembly includes an ankle member, a heel member pivotally connected to the ankle member, an elongate metatarsal-toe member having a rear portion underlying a forward portion of the heel member and projecting forwardly from the heel member. The metatarsal-toe member being pivotally connected to the heel member. A first compressible element is engaged between a portion of the ankle member and a portion of the heel member and a second compressible element having first and second substantially circular bearing surfaces engaged between a portion of the heel member and a portion of the metatarsal-toe member to resist upward pivotal movement of a forward end of the metatarsal-toe member relative to the heel member. A portion of the compressible element spaced apart from one of the bearing surfaces has a smaller diameter than the diameter of at least one of the first and second bearing surfaces.

This invention provides a linear stapling instrument for use in surgical procedures including, inter alia, a staple housing. The housing includes a plurality of staple openings and a plurality of staples disposed in the staple openings. The housing further includes a plurality of staple drivers. The staple drivers have an upper surface bearing on a staple and a lower camming surface. The staple drivers are slidably mounted in the housing for movement from an initial lower position to an upper position. They also are arranged such that their lower camming surfaces are disposed in one or more spaced rows. The housing also includes a sled slidably mounted in the housing for movement from an unfired position to a fired position. The sled has at least one camming surface. The camming surface is disposed on the sled such that movement of the sled from its unfired to its fired position causes the camming surface to contact in sequence the lower camming surface of the staple drivers in at least one the row. The staple drivers, thus, are cammed from their lower to their upper positions, and they in turn eject the staples from the staple openings.

Linear stapling instrument with improved staple cartridge

This invention provides an articulated surgical instrument for use in laparoscopic surgical procedures including, in general, a handle, an elongated shaft, and a tip. The shaft is coupled to the handle, and the tip is pivotally coupled to the distal end of the shaft for articulation about an articulation axis. The tip includes two opposed jaws. The jaws are pivotally coupled at a pivot axis for movement between an open position and a closed position, and at least one of the jaws has a camming portion proximal to the pivot axis of the jaws. The instrument further includes a camming driver disposed in the shaft for reciprocating movement between a proximal position and a distal position. The camming driver has a camming portion. The drive camming portion contacts the jaw camming portion at a cam point. Preferably, the jaw camming portion is a hemispherically-shaped projection and the driver camming portion is a ramp. Movement of the camming driver from its proximal position to its distal position causes the jaws to pivot from their open position to their closed positions.

Articulated surgical instrument with improved jaw closure mechanism

This invention provides articulated surgical instruments for use in laparoscopic surgical procedures including, in general, a handle, an elongated shaft, and an articulated tip. A gap extends longitudinally between the shaft and the tip. The instruments further include a flexible compression drive member, preferably a flexible cable, which is slidably disposed in the shaft and extends through the gap. The flexible drive member bends through the gap in a plane of articulation when the tip is articulated. A flexible support is attached at one end to the shaft and at another end to the tip. At least one of those connections is a slidable connection. The support extends through the articulation joint adjacent to the flexible drive member in the plane of articulation such that the support bends through the gap in the plane of articulation and the flexible drive member bends against the support when the tip is articulated in one direction from its aligned position. Preferably, the instruments include a pair of such supports extending adjacent to opposite sides of the flexible drive member.
