Abstract
Abstract A prosthetic holder is disclosed having prosthetic-grasping jaws located distally, a jaw hinge located centrally, and a jaw locking mechanism located proximally. The locking mechanism can be operated from either side of the holder, and includes studs fixed to each jaw. The studs can be brought into arcuate superimposition, and the jaws into a corresponding prosthesis grasping position, by a locknut carried on one stud. Removable liners are provided for engaging various shaped prostheses.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A prosthesis holder including a pair of opposing jaws adapted for grasping a prosthesis, a short and a long locking stud, one stud mounted on each jaw for angular motion therewith, a locking member carried on the long stud for selectively engaging the short stud and urging the short stud into angular superposition over the long stud, thereby simultaneously urging said holder jaws into their prosthesis grasping position and hinge means for mounting the jaws to one another so as to permit relative angular motion therebetween, said hinge means being located between said jaws and said locking member.
Claim 2
Dependent Claim
98 words
A prosthesis holder including a pair of opposing jaws adapted for grasping a prosthesis, a short and a long locking stud, one stud mounted on each jaw for angular motion therewith, a locking member carried on the long stud for selectively engaging the short stud and urging the short stud into angular superposition over the long stud, thereby simultaneously urging said holder jaws into their prosthesis grasping position and hinge means for mounting the jaws to one another so as to permit relative angular motion therebetween, said hinge means being located between said jaws and said locking member.
Claim 3
Dependent Claim
57 words
A prosthesis holder according to claim 1 wherein said holder jaws each include a cylindrical mounting collar member, the mounting member in cross section describing substantially a circular arc of substantially 180*, and a liner member having an inner face adapted to engage the prosthesis and an outer face adapted to securely engage the jaw mounting collar.
Claim 4
Dependent Claim
42 words
A prosthesis holder according to claim 1 wherein each liner member includes tip portions formed to overhang and engage said mounting collar member and at least one guide slot formed to engage a locating stop lug formed on said mounting collar member.
Claim 5
Dependent Claim
82 words
A locking mechanism for a prosthesis holder having a pair of hinged jaws for angular motion to and from a prosthetic grasping position; said locking device including a short and a long locking stud, one stud mounted on each jaw for angular motion therewith, and a locking member carried on the long stud for selectively engaging the short stud and urging the short stud into angular superposition over the long stud, thereby simultaneously urging said holder jaws into their prosthetic grasping position.
Claim 6
Dependent Claim
82 words
A locking mechanism for a prosthesis holder having a pair of hinged jaws for angular motion to and from a prosthetic grasping position; said locking device including a short and a long locking stud, one stud mounted on each jaw for angular motion therewith, and a locking member carried on the long stud for selectively engaging the short stud and urging the short stud into angular superposition over the long stud, thereby simultaneously urging said holder jaws into their prosthetic grasping position.
Claim 7
Dependent Claim
62 words
A locking device according to claim 4 wherein said locking member is threadedly attached to said long stud for axial motion therealong, motion of the locking member toward said jaws bringing the locking member into engagement with said short stud, and further lock member motion toward the jaws urging the short stud into progressively more exact angular superposition over the long stud.
Claim 8
Dependent Claim
31 words
A locking device according to claim 4 wherein said locking member is a locknut having a conical interior surface for engaging a terminal portion of at least the short locking stud.
Claim 9
Dependent Claim
36 words
A locking device according to claim 6 wherein said locking mechanism includes a jam nut threadedly attached to said long locking stud for jamming said locking member in a given location on said long locking stud.
