Abstract
Surgical devices and methods for their use in manipulating internal body objects are provided. The subject devices have proximal and distal ends separated by an elongate member. Located at the distal end is at least one articulated member, and usually two or more articulated members. A manual means for actuating the one or more distal articulated members is located at the proximal end of the device. The elongate member may be flexible or rigid. The subject devices find use in a variety of applications, and are particularly suited for use in applications in which it is desired to manipulate an internal body object from a location external to the body.
Claims25
A surgical device comprising:
- proximal and distal ends;
- at least one articulated member comprising a shape memory element located at said distal end, wherein said articulated member comprises compression means for preventing hyperextension of said member and joints that are not pinned hinge joints;
- and
- a manual actuation means located at said proximal end for actuating said at least one articulated member.
A surgical device comprising:
- proximal and distal ends separated by an elongate member;
- at least one articulated member comprising a shape memory element located at said distal end, wherein said articulated member comprises joints that are not pinned hinge joints;
- and
- a manual actuation means located at said proximal end for actuating said at least one articulated member.
A surgical device comprising:
- proximal and distal ends;
- a plurality of articulated members located at said distal end, wherein each articulated member of said plurality comprises a shape memory element and is individually actuatable relative to any other articulated member of said plurality and comprises joints that are not pinned hinge joints;
- and
- a manual actuation means located at said proximal end for independently actuating each articulated member of said plurality.
