Abstract
A prosthetic apparatus and system for a trans-tibial amputee consisting of a post-operative interface socket that can be adjusted to accommodate the size of an amputated limb and changes in size of the limb. The prosthetic apparatus includes a lower socket into which the post-operative socket can be inserted, the lower socket being adjustable for changes in size of the post-operative interface socket. The post-operative socket also has a removable upper back shell that immobilizes movement of the knee during an initial recovery phase but can be removed to allow the knee of the amputee to flex.
Claims24
An interface socket for a trans-tibial amputee comprising:
- a. a base cup;
- b. a lower back shell attached to said base cup by a flexible back strut having a first end and a second end;
- i. said first end being connected to said lower back shell at a point above a bottom edge of said lower back shell with a first set of open ended slots on either side of said flexible back strut, said first set of open ended slots open at said bottom edge of said lower back shell and terminate at opposite closed ends where said first end of said flexible back strut connects to said lower back shell;
- ii. said second end being connected to a bottom of said base cup with a second set of open ended slots on either side of said flexible back strut, said second set of open ended slots open at a rim of said base cup and terminate at a closed end adjacent to said connection of said second end to said bottom of said base cup;
- and
- iii. said back strut having a bend in it that positions a plane formed by said base of said base cup approximately perpendicular to a plane formed by a line up a middle of said lower back shell;
- c. an upper back shell connected to a top edge of said lower back shell;
- d. a front shell connected to said base cup by a flexible front strut;
- e. wherein said interface socket is made of a flexible, resilient and formable material;
- f. wherein said lower back shell is movable in relation to said front shell to vary said space between said lower back shell and said front shell;
- and
- g. wherein said front shell and said lower back shell with said upper back shell attached are positioned to form a space therebetween to receive a limb of a trans-tibial amputee and be adjusted to vary the space therebetween to hold and grip said limb in a secure and comfortable fashion.
A lower socket for holding and supporting an interface socket comprising:
- a. a bottom cup;
- b. a front shell connected to a front top edge of said bottom cup;
- c. a back shell attached to said bottom cup by an articulated adjustable strut;
- d. wherein said lower socket is made of a flexible, resilient and formable material;
- and
- e. wherein said articulated adjustable strut comprises a center plate with a first plate hingedly attached at a first edge of said center plate and a second plate attached at a second edge or said center opposite said first edge, wherein said first plate is detachably connected to said back shell and said second plate is detachably connected to said bottom cup;
- and
- f. wherein said front shell and said back shell form an interior space to accept an interface socket and said space between said front shell and said back shell can be varied by movement of said articulated strut to accommodate post-operative interface sockets of varying sizes.
A prosthetic system for amputees that have undergone a trans-tibial amputation comprising:
- a, a post-operative interface socket comprising:
- i. a base cup;
- ii. a lower back shell attached to said base cup by a flexible back strut having a first end and a second end,
- said first end being connected to said lower back shell at a point above a bottom edge of said lower back shell with a first set of open ended slots on either side of said flexible back strut, said first set of open ended slots open at said bottom edge of said lower back shell and terminate at their opposite end where said first end of said flexible back strut connects to said lower back shell;
- said second end being connected to a bottom of said base cup with a second set of open ended slots on either side of said flexible back strut, said second set of open ended slots open at a rim of said base cup and terminate at a closed end adjacent to said connection of said second end to said bottom of said base cup;
- and
- said back strut has a bend in it that positions a plane formed by said base of said base cup approximately perpendicular to a plane of formed by a line up a middle of said lower back shell;
- iii. an upper back shell connected to a top edge of said lower back shell;
- iv. a front shell connected to said base cup by a flexible front strut, said flexible front strut having a first end and a second end, said first end connected to a portion of said rim of said base cup opposite a bottom edge of said front shell, and said second end connected to a portion of a bottom of said front shell with open ended slots on either side of said flexible front strut forming said bottom edge of said front shell separated from and opposite from a portion of said rim of said base cup;
- v. wherein said interface socket is made of a flexible, resilient and formable material;
- and
- vi. wherein said lower back shell is movable in relation to said front shell to vary said space between said lower back shell and said front shell;
- vii. wherein said structure described allows for a flexing of side edges of said front shell to thereby allow said side edges of said front shell to slip inside of outside of edges of said lower back shell;
- and
- viii. wherein said front shell and said back shell are positioned to form a space there between to receive a limb of a trans-tibial amputee and be adjusted to vary the space there between to hold and grip said limb in a secure and comfortable fashion;
- b. A lower socket for holding and supporting said post-operative interface socket comprising:
- i. a bottom cup:
- ii. a front shell connected to a top edge of a front of said bottom cup;
- iii. a back shell attached to said bottom cup by an articulated adjustable strut;
- iv. wherein said lower socket is made of a flexible, resilient and formable material;
- and
- v. wherein said front shell and said back shell form an interior space to accept a post-operative interface socket and said space between said front shell and said back shell can be varied by movement of said articulated strut to accommodate post-operative interface sockets of varying sizes.
A single socket adjustable prosthetic system comprising:
- a. a first shell with an extended surface configured to fit against a first side of an amputee's limb, said surface terminating at a base, said base configured to extend under the amputee's limb and said base having a limb facing surface and a bottom surface;
- b. a second shell with an extended surface configured to fit against a second side of the amputee's limb;
- c. an articulated hinge having three plates, a center plate with a first plate hingedly attached at a first end of said center plate and a second plate hingedly attached at a second end of said center plate, with said first plate of said articulated hinge attached to said base and said second plate of said articulated hinge attached to said second shell;
- and
- d. said articulated hinge connected at said first plate to said base of said first shell and connected at said second plate to said second shell forms a space between said first shell and said second shell, said space to be varied to hold, and accommodate swelling and shrinking of the amputee's limb.
