Abstract

A surgical apparatus for simultaneously deploying a first instrument while retrieving a second instrument from the distal end of a sheath and vice versa with a single stroke actuator. The actuator includes an elongated support having a provision for grasping at one end thereof, a first sliding member having provisions for grasping and which is movable in first and second directions relative to the support, and a second sliding member operably coupled to the first sliding member such that translation of the first and second sliding members is in opposite directions relative to the support. The first sliding member is connected to the first instrument and the second sliding member is connected to the second instrument.

Claims

1. An apparatus comprising:

a first instrument including an injection needle;

a second instrument including a snare;

sheathing means for sheathing said first and second instruments, said sheathing means having a proximal end and a distal end; and

actuator means for simultaneously extending said first instrument relative to said distal end of said sheathing means in a first direction and retracting said second instrument in a second direction relative to said distal end of said sheathing means, and for simultaneously extending said second instrument relative to said distal end of said sheathing means in said first direction and retracting said first instrument in said second direction relative to said distal end of said sheathing means.

2. The surgical apparatus recited in claim 1, wherein said actuator means comprises:

a support having means for grasping thereof;

a handle having means for grasping thereof, said handle slidably connected to said support for movement in said first direction and said second direction relative thereto and connected to at least one of said first instrument and said second instrument; and

slide means for enabling movement of said first instrument and said second instrument in opposite directions, said slide means movable with respect to said support and operably connected to said handle.

3. The surgical apparatus recited in claim 2, wherein said operable connection between said slide means and said handle comprises an elongated endless belt and at least first and second axles affixed relative to said support, said endless belt being disposed about said axles and attached to said slide means and attached to said handle for causing said slide means to move in said first and second directions relative to said support.

4. An apparatus, comprising:

a first instrument;

a second instrument;

sheathing means for sheathing said first and second instruments, said sheathing means having a proximal end and a distal end; and

actuator means for simultaneously extending said first instrument relative to said distal end of said sheathing means in a first direction and retracting said second instrument in a second direction relative to said distal end of said sheathing means, and for simultaneously extending said second instrument relative to said distal end of said sheathing means in said first direction and retracting said first instrument in said second direction relative to said distal end of said sheathing means; and

locking means for maintaining at least one of said first and second instruments in a retracted position within said sheathing means, said locking means requiring manual manipulation thereof to facilitate extension and retracting of said at least one of said first and second instruments relative to said sheathing means.

5. A surgical apparatus, comprising:

a needle attached to an elongated extension line for communicating fluids to and from said needle, said needle being extendable in a first direction and retractable in a second direction;

a snare attached to an elongated extension line and extendable in said first direction when said needle is retracted in said second direction and retractable in said second direction when said needle is extended in said first direction;

sheathing means for sheathing said needle, said snare and said extension lines, said sheathing means having a proximal and a distal end; and

actuator means for simultaneously extending said needle in said first direction and retracting said snare in said second direction, relative to said distal end of said sheathing means.

6. A surgical apparatus, comprising:

a needle attached to an elongated extension line for communicating fluids to and from said needle, said needle being extendable in a first direction and retractable in a second direction;

a snare attached to an elongated extension line and extendable in said first direction when said needle is retracted in said second direction and retractable in said second direction when said needle is extended in said first direction;

sheathing means for sheathing said needle, said snare and said extension lines, said sheathing means having a proximal and a distal end; and

actuator means for extending said needle in said first direction and retracting said snare in said second direction, relative to said distal end of said sheathing means;

said actuator means including;

a support having means for grasping thereof;

a first slide slidably connected to said support for movement in said first direction and said second direction relative thereto and connected to at least one of said needle and said snare; and

a second slide for enabling movement of said needle and said snare in opposite directions, said second slide being movable with respect to said support and operably connected to said first slide.

7. A surgical apparatus, comprising:

a first instrument extendable in a first direction and retractable in a second direction;

a second instrument extendable in said first direction as said first instrument is being retracted in said second direction and retractable in said second direction as said first instrument is being extended in said first direction;

sheathing means for sheathing said first and second instruments, said sheathing means having a proximal end and a distal end;

a support having means for grasping thereof, said support and said sheathing means being secured together for movement as a unit;

a handle having means for grasping thereof, said handle being slidably connected to said support for movement in a first direction and a second direction relative thereto and connected to at least one of said first instrument and said second instrument; and

slide means for enabling movement of said first instrument and said second instrument in opposite directions, said slide means being movable with respect to said support and operably connected to said handle.

8. An apparatus comprising:

a first instrument;

a second instrument;

sheathing means for sheathing said first and second instruments, said sheathing means having a proximal end and a distal end; and

actuator means for simultaneously extending said first instrument relative to said distal end of said sheathing means in a first direction and retracting said second instrument in a second direction relative to said distal end of said sheathing means, and for simultaneously extending said second instrument relative to said distal end of said sheathing means in said first direction and retracting said first instrument in said second direction relative to said distal end of said sheathing means;

said sheathing means and said actuator means being secured together for movement as a unit.
