Abstract
An endoscopic apparatus for the continuous application of a suture includes a suturing body that is shaped and dimensioned for attachment to the distal end of a commercially available endoscope in a manner permitting actuation thereof. The suturing body is composed of a suture housing in which a needle and drive assembly are housed for movement of the needle about a continuous circular path facilitating the application of a suture secured to a distal end of the needle. The drive assembly includes a rocker that moves along the suture housing under the control of a drive cable and a pin, wherein actuation of the drive cable and pin cause the rocker to selectively engage and disengage the needle causing the needle to move about a circular path in a continuous manner.

An endoscopic apparatus for the continuous application of a suture, comprising:
- a suturing body that is shaped and dimensioned for attachment to the distal end of a commercially available endoscope in a manner permitting actuation thereof;
- the suturing body is composed of a suture housing in which a needle and drive assembly are housed for movement of the needle about a continuous circular path facilitating the application of a suture secured to a distal end of the needle, the suture housing including a first track in which the needle is positioned, a second track and a third track;
- the drive assembly includes a rocker that moves along the second track of the suture housing under the control of a drive cable and a pin that moves along the third track of the suture housing, wherein actuation of the drive cable and pin cause the rocker to selectively engage and disengage the needle causing the needle to move about a circular path in a continuous manner.
An endoscope for the continuous application of a suture, comprising:
- an endoscope body;
- a suturing body that is shaped and dimensioned for attachment to the distal end of the endoscope body in a manner permitting actuation thereof;
- the suturing body is composed of a suture housing in which a needle and drive assembly are housed for movement of the needle about a continuous circular path facilitating the application of a suture secured to a distal end of the needle, the suture housing including a first track in which the needle is mounted, a second track and a third track;
- the drive assembly includes a rocker that moves along the second track of the suture housing under the control of a drive cable and a pin that moves along the third track of the suture housing, wherein actuation of the drive cable and pin cause the rocker to selectively engage and disengage the needle causing the needle to move about a circular path in a continuous manner.
