System for single-puncture endoscopic surgery
First Claim
1. A system for single-puncture endoscopic surgery comprising:
- a cannula divided longitudinally into a first channel and a second channel;
an optically clear cap sealingly attached adjacent to a distal end of the first channel, thereby forming a camera compartment;
a camera adapted to be inserted in the camera compartment; and
a light generating source adapted to be inserted in the camera compartment;
wherein the system is adapted for use with an instrument having an elongated shaft, the system further comprising an engagement member attached to the cannula, the engagement member being adapted to engage the instrument at a portion of the instrument that is spaced from the elongated shaft when the instrument is inserted into the second channel, so that manipulation of the portion of the instrument that is spaced from the elongated shaft can simultaneously alter positioning of the camera and the elongated shaft of the surgical instrument.

Abstract
A cannula is divided longitudinally into a camera chamber and an instrument passage. The distal end of the camera is sealed by an optically clear member. In use, a camera assembly which includes a camera sled on which are mounted a charge-coupled device camera and lights is inserted into the camera chamber and a conventional laparoscopic instrument is inserted into the patient through the instrument passage. The camera sled is isolated from the patient by the cannula, eliminating the need to sterilize the camera sled. The instrument is held in position by an attachment member which extends from the cannula. This allows the surgeon to control the position of the instrument and the camera with one hand. The cannula includes a port for connecting a source of CO2 to inflate the patient'"'"'s abdominal cavity and a port for connecting a conventional suction/irrigation trumpet-valve assembly.

2. An endoscopic sheath for use with a surgical instrument having an elongated shaft, the sheath comprising:
-
a cannula to receive an endoscope and the elongated shaft of the surgical instrument; and an engagement member, attached to the cannula, adapted to releasably engage a portion of the surgical instrument that is spaced from the elongated shaft, so that manipulation of the portion of the surgical instrument spaced from the elongated shaft can simultaneously alter positioning of the endoscope and the elongated shaft of the surgical instrument. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

28. A method of performing endoscopic surgery on a patient using a laparoscopic surgical instrument having a handle and an elongated shaft, the elongated shaft of the laparoscopic surgical instrument being disposed in a cannula having a docking member, the cannula further having a viewing assembly disposed therein to allow viewing of a surgical site, the method comprising the steps of:
-
engaging a portion of the surgical instrument that is spaced from the elongated shaft with the docking member; and manipulating the viewing assembly and the surgical instrument simultaneously by manipulating a portion of the surgical instrument spaced from the elongated shaft. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
