Abstract

An endoscopic surgical instrument is used in minimally invasive laparoscopic surgery for inserting a gastric band into a patient'"'"'s abdomen through a laparoscopic port. The gastric band insertion instrument includes a handle, an elongated shaft and a distal end assembly. The elongated shaft includes an actuator rod that opens and closes a movable jaw at the distal end. A pin at the distal end assembly engages a hole in the front of the gastric band, and the movable jaw is closed thereby securely capturing the front end of the gastric band. The shaft and the captured gastric band are inserted through a laparoscopic port into the patient'"'"'s abdomen.

Claims

1. A method for inserting an elongated strap via minimally invasive surgery into a patient'"'"'s body the method comprising:

providing an elongated strap comprising a buckle end and a distal end, said buckle end comprising a pull tab;

providing an elongated shaft extending along a longitudinal axis, wherein said elongated shaft comprises a handle attached to a proximal end of said elongated shaft and an end assembly attached to a distal end of said elongated shaft, and wherein said end assembly comprises a flat member having a first end attached to said distal end of said elongated shaft, a rounded cone-shaped nose extending from a second end of said flat member, and a movable jaw articulately connected to said second end of said flat member;

engaging a hole in said pull tab with said end assembly and securely capturing said pull tab;

inserting said elongated shaft with the captured elongated strap into the patient'"'"'s body; and

pushing said pull tab and thereby said elongated strap through into the patient'"'"'s body.

2. The method of claim 1 wherein said flat member further comprises a top surface having a pin projecting from it and wherein said pin is configured to first engage said hole in said pull tab and then said movable jaw is configured to close downward over said pin, and thereby securely capturing said pull tab between said pin and said closed movable jaw.

3. The method of claim 2 wherein said elongated shaft comprises a hollow tube and said hollow tube encloses an actuator rod configured to move back and forth along said longitudinal axis, and wherein said actuator rod is connected to said movable jaw and is configured to actuate said movable jaw through said back and forth motion.

4. The method of claim 3 wherein said handle comprises a collar configured to slide back and forth along said handle and thereby to move said actuator rod back and forth along said longitudinal axis.

5. The method of claim 2 wherein said handle is configured to provide tactile control of said movable jaw orientation.

6. The method of claim 2 wherein said handle comprises a cylindrical body having first and second side indentations opposite to each other and a thumb indentation on a top surface of said cylindrical body, said thumb indentation being aligned with said movable jaw.

7. The method of claim 1 further comprising inserting a minimally invasive cannula into the patient'"'"'s body and inserting said elongated shaft through said cannula into the patient'"'"'s body.

8. The method of claim 7 wherein said elongated shaft is dimensioned to enter one end, pass through and extend beyond the other end of said cannula.

9. The method of claim 7 wherein said rounded cone-shaped nose opens seals and gates in a port of said cannula.

10. The method of claim 7 wherein said elongated strap encircles an internal organ and said distal end passes through and lockingly engage said hole thereby tightening said elongated strap around said internal organ.
