Abstract
Tissue manipulation and retraction devices. In various forms, the manipulation devices include a cannula that is insertable through the abdominal wall. A plurality of independently controllable manipulation members extend through the cannula and are attachable to various forms of surgical tools. The surgical tools may be manipulated and controlled by a surgeon from a position outside of the patient.
Claims20
A tissue manipulation device, comprising:
- a hollow cannula having a distal and a proximal end;
- a plurality of manipulation members, each said manipulation member having a manipulation distal end;
- an adjustment assembly coupled to said proximal end of said hollow cannula and operably interfacing with each of said plurality of manipulation members to selectively apply thereto separate actuation motions thereto;
- and
- at least one surgical tool removably coupled to at least one of said plurality of manipulation members, wherein each said surgical tool is at least initially configured to pass through said cannula.
2 more elements
The tissue manipulation device of claim I wherein said adjustment assembly is operably supported on a body coupled to said proximal end of said hollow cannula and wherein said adjustment assembly comprises:
- a plurality of actuator members operably supported on said body wherein each of said rotatable wheels operably interfaces with a corresponding one of said plurality of manipulation members;
- and
- locking means interfacing with said plurality of actuator members for selectively locking said actuator members in unactuatable positions.
A tissue manipulation device comprising:
- a body portion;
- a hollow cannula coupled to said body portion and having a distal end configured to puncture tissue;
- a first manipulation cable extending through said hollow cannula, said first manipulation member coupled to a first rotatable disc assembly operably supported by said body portion such that by rotating said first rotatable disc assembly in a first deployment direction, a first portion of said first manipulation cable is deployed in a first distal direction relative to said distal end of said hollow cannula and by rotating said first rotatable disc assembly in a first actuation direction, said first portion of said first manipulation cable is moved in a first proximal direction relative to said distal end of said cannula;
- a first releasable lock member interfacing with said first rotatable disc assembly to selectively prevent rotation of said first rotatable disc assembly;
- a second manipulation cable extending through said hollow cannula, said second manipulation member coupled to a second rotatable disc assembly operably supported by said body portion such that by rotating said second rotatable disc assembly in a second deployment direction, a second portion of said second manipulation cable is moved in a second distal direction relative to said distal end of said hollow cannula and by rotating said second rotatable disc assembly in a second actuation direction, said second portion of said second manipulation cable is moved in a second proximal direction toward said distal end of said cannula;
- a second releasable lock member interfacing with said second rotatable disc assembly to selectively prevent rotation of said second rotatable disc assembly;
- a third manipulation cable extending through said hollow cannula, said third manipulation member coupled to a third rotatable disc assembly operably supported by said body portion such that by rotating said third rotatable disc assembly in a third deployment direction, a third portion of said third manipulation cable is moved in a third distal direction relative to said distal end of said hollow cannula and by rotating said third rotatable disc assembly in a third actuation direction, said third portion of said third manipulation cable is moved in a third proximal direction toward said distal end of said cannula;
- a third releasable lock member interfacing with said third rotatable disc assembly to selectively prevent rotation of said third rotatable disc assembly;
- and
- at least one surgical tool removably couplable to a distal end of at least one of said first, second and third manipulation cables, said at least one surgical tool selected from a group of surgical tools comprising:
- a grasping device;
- and
- a substantially flexible tissue-retaining net.
10 more elements
A surgical procedure comprising:
- installing a cannula through a patient's abdominal wall such that a distal end of the cannula protrudes into the patient's abdomen, the cannula having a plurality of manipulation cable assemblies protruding out of the distal end of the cannula into the patient's abdomen wherein each of the manipulation cable assemblies are independently selectively actuatable relative to each other;
- coupling a first surgical tool to an end of one of the manipulation cable assemblies;
- coupling a second surgical tool to another end of another one of the manipulation cable assemblies;
- applying an actuation motion to the first surgical tool through the one manipulation cable assembly coupled thereto;
- and
- applying another actuation motion to the second surgical tool through the another one of the manipulation cable assemblies attached thereto.
