Abstract

An apparatus and method of performing a cholecystectomy procedure through a 3-centimeter incision in the minimum stress triangle through the falciform ligament which provides for direct vertical view of the biliary ducts during dissection. Special tools are provided for this type and other types of surgical operations including obtuse-angled retractors having optionally fixed thereto lighting devices and/or suction devices.

Claims

1. A combination self-retaining surgical retractor, lighting device, and suction means apparatus, comprising:

a substantially stationary toothed arm having a first end and a second end;

a toothed cross bar also having a first end and a second end;

said toothed cross bar first end being secured to said first end of said substantially stationary toothed arm in a generally perpendicular relation and forming a generally L-shaped section;

a moveable toothed arm having a first end and a second end;

said first end of said moveable toothed arm having a housing with a slotted opening which is attachable to said toothed cross bar and is laterally moveable along the length of said cross bar;

a plurality of self-retaining surgical retractors;

a lighting device which is unitary with at least one of said self-retaining surgical retractors;

suction means which is unitary with at least one of said self-retaining surgical retractors; and

each of said self-retaining surgical retractors being releasably securable to said substantially stationary toothed arm, said toothed cross bar, or said moveable toothed arm.

2. Apparatus according to claim 1, including:

securement means for releasably and moveably securing an associated self-retaining surgical retractor to said substantially stationary toothed arm, said toothed cross bar, or said moveable toothed arm; and

said securement means permits moveable positioning of said associated self-retaining retractor including pivotal motion of said associated retractor with respect to a plane containing said substantially stationary toothed arm, said toothed cross bar, and said moveable toothed arm.

3. Apparatus according to claim 2, including:

first finger-actuatable locking and unlocking means positioned on a first side of said securement means for controlling the pivotal orientation of said associated retractor with respect to said plane;

second finger-actuatable means for releasably locking and unlocking said associated retractor for controlling the position of said retractor along its central elongated axis relative to said securement means;

said second finger-actuatable means being located on a second side of said securement means which is opposite said first side; and

said lighting device includes a fiberoptic carrier.

4. Apparatus according to claim 2, wherein:

said lighting device includes a fiberoptic light carrier.

5. Apparatus according to claim 2, wherein:

said lighting device includes a light radiating portion which is oriented obliquely to major edges of its associated retractor.

6. Apparatus according to claim 5, wherein:

said lighting device includes a fiberoptic light carrier.

7. Apparatus according to claim 2, including:

a rotatable hand knob upwardly connected with said housing; and

whereby rotation of said hand knob causes said moveable toothed arm to move along said toothed cross bar.

8. Apparatus according to claim 1, including:

securement means for releasably and moveably securing an associated self-retaining surgical retractor to said substantially stationary toothed arm, said toothed cross bar, or said moveable toothed arm;

said securement means permits moveable positioning of said associated self-retaining retractor including pivotal motion of said associated retractor with respect to a plane containing said substantially stationary toothed arm, said toothed cross bar, and said moveable toothed arm; and

first finger-actuatable locking and unlocking means positioned on a first side of said securement means for controlling the pivotal orientation of said associated retractor with respect to said plane.

9. Apparatus according to claim 8, including:

second finger-actuatable means for releasably locking and unlocking said associated retractor for controlling the position of said retractor along its central elongated axis relative to said securement means;

said second finger-actuatable means being located on a second side of said securement means which is opposite said first side; and

said lighting device includes a light-radiating portion which is oriented obliquely relative to major edges of its associated self-retaining retractor.

10. Apparatus according to claim 9, wherein:

said lighting device includes a fiberoptic light carrier.

11. Apparatus according to claim 8, wherein:

said lighting device includes a fiberoptic light carrier.

12. Apparatus according to claim 1, wherein:

said substantially stationary toothed arm, said toothed cross bar, and said moveable toothed arm each comprise a toothed external member having teeth disposed along at least one edge thereof;

each of said self-retaining surgical retractors has sawtooth teeth disposed along a portion thereof;

said apparatus further includes securement means for releasably and moveably securing an associated one of said surgical retractors to a desired one of said toothed external members, said securement means comprising;

a first housing having a first channel therein for securement to said desired one of said toothed external members;

a second housing pivotally secured to said first housing;

said second housing having a toothed sector depending therefrom and being provided with a channel through which said sawtooth teeth portion of said associated surgical retractor may be disposed;

said second housing being provided with a first finger-activatable control mechanism which permits releasably locking and unlocking of said associated surgical retractor in a desired position relative to said second housing;

said first finger-activatable control mechanism being disposed on a first side of said second housing;

a second finger-activatable control mechanism being disposed on a second side of said second housing which is opposite to said first side thereof;

said first housing having a second channel therein for accommodating said toothed sector and being dimensioned such that no portion of said toothed sector will protrude through a surface of said first housing which is remote from said second housing;

said first housing being provided with a spring-biased latching member which is adapted to releasably latch with the teeth of said toothed sector; and

said second finger-activatable control mechanism being operable to move said spring-biased latching member.

13. Apparatus according to claim 1, including:

securement means for releasably and moveably securing an associated self-retaining surgical retractor to said substantially stationary toothed arm, said toothed cross bar, or said moveable toothed arm;

said securement means permits moveable positioning of said associated self-retaining retractor including pivotal motion of said associated retractor with respect to a plane containing said substantially stationary toothed arm, said toothed cross bar, and said moveable toothed arm;

first finger-actuatable locking and unlocking means positioned on a first side of said securement means for controlling the pivotal orientation of said associated retractor with respect to said plane;

second finger-actuatable means for releasably locking and unlocking said associated retractor for controlling the position of said retractor along its central elongated axis relative to said securement means; and

said second finger-actuatable means being located on a second side of said securement means which is opposite said first side.

14. Apparatus according to claim 1, wherein:

said lighting device includes a fiberoptic light carrier.

15. Apparatus according to claim 1, wherein:
