Abstract

A staple delivery applicator for delivering radioactive staples during brachytherapy medical treatment has an actuating device for attaching source staples located distally thereform. The actuating device is removably attachable to an actuator arm on a proximal end. A staple applicator cartridge holder is attached to the actuator arm on a distal end. The staple applicator cartridge is mountable in the holder and has slots for mounting of radioactive source staples therein. An anvil therein crimps the staples. The staple applicator cartridge holder is removably mountable in a connector and the connector is also removably mounted to a surgical staple holder. A trigger device has a control for closing the anvil of the cartridge holder and for firing of the source staples in the cartridge therein to cause the staples to crimp, and a control for opening the anvil and releasing the trigger device from the actuator arm.

Claims

1. A staple delivery applicator for delivering radioactive source staples during a medical treatment, said staple delivery applicator comprising:

an actuating means, said actuating means for controlling crimping of the source staples located distally from said actuating means, wherein a trigger device comprises;

a hand holding section, a lever mounted in said hand holding section;

a control section, said control section having one or more controls therein for crimping staples located distally from said trigger device, said control section having a control for closing an anvil of a source cartridge holder and for firing of source staples in a source staple cartridge therein to cause the staples to crimp, and a control for opening the anvil and releasing said trigger device, the lever being pivotally mounted to a reversible gear and operatively connected to a control cable within an actuator arm for controlling said source cartridge holder; and

an actuator arm mounting section;

said actuating means being removably attachable to said actuator arm on a proximal end; and

a modular connector with two modular units, one modular unit being adapted to removably hold said source cartridge holder, the other modular unit being adapted to removably hold a surgical staple cartridge holder, said units being removably mounted together in said modular connector when in use, said source cartridge holder operatively attached to said actuator arm on a distal end and adapted to removably mount therein said source staple cartridge;

wherein said actuating means is adapted for closing the anvil of said source cartridge holder and for firing of the source staples in said source staple cartridge therein to cause the staples to crimp, and opening and closing of the anvil by movement of the control cable.

2. The staple delivery applicator as recited in claim 1, wherein said modular unit for said cartridge holder may be mounted to either side of the modular unit for holding said surgical staple cartridge holder.

3. The staple deliver applicator as recited in claim 2, wherein said modular connector further includes radiation shielding.

4. A staple delivery applicator for delivering radioactive source staples during medical treatment, said staple delivery applicator comprising:

an actuating means, said actuating means for controlling crimping of the source staples located distally from said actuating means;

an actuator arm, said actuating means being removably attachable to said actuator arm on a proximal end;

a source cartridge holder, said source cartridge holder operatively attached to said actuator arm on a distal end and adapted to removably mount therein a source staple cartridge;

a modular connector with two modular units, one modular unit being adapted to removably hold said source cartridge holder, the other modular unit being adapted to removably hold a surgical staple cartridge holder, said units being removably mounted together in said modular connector when in use,

wherein said actuating means is adapted for closing an anvil of said source cartridge holder and for firing of source staples in said source staple cartridge therein to cause the staples to crimp, and opening and closing of the anvil.

5. The staple delivery applicator as recited in claim 4, wherein said modular unit for said source cartridge holder may be mounted to either side of the modular unit for holding said surgical staple cartridge holder.

6. The staple deliver applicator as recited in claim 4, wherein said modular connector further includes radiation shielding.
