Abstract
An apparatus (10) supports an endoscope (200) for viewing a surgical site in a patient during surgery on the patient. The apparatus (10) includes a base (118), a part (140) adapted to be fixed to the endoscope (200), and a screw mechanism (160). The base (118) has a guide portion (128). The part (140) engages the guide portion (128) and is movable relative to the guide portion (128). The screw mechanism (160) connects between the base (118) and the part (140). At least a portion (610) of the screw mechanism (160) is rotatable to slide the part (140) relative to the guide portion (128) to change a position of the endoscope (200) relative to the patient. In another feature of the apparatus (10), the apparatus (10) may include a cannula clamp 180 secured to a cannula (11) and rotatable relative to the part (140).
Claims42
An apparatus for supporting an endoscope for viewing a surgical site in a patient during surgery on the patient, said apparatus comprising:
- a base having a guide portion;
- a part adapted to be fixed to the endoscope, said part engaging said guide portion and being movable relative to said guide portion;
- and
- a screw mechanism connected between said base and said part, at least a portion of said screw mechanism being rotatable to slide said part relative to said guide portion to change a position of the endoscope relative to the patient.
An apparatus for supporting an endoscope for viewing a surgical site in a patient during surgery on the patient, the endoscope extending through a cannula into the patient, said apparatus comprising:
- a base;
- a support mechanism for supporting the endoscope on said base;
- a cannula clamp for clamping against an outer surface of the cannula;
- and
- a connection between said base and said cannula clamp, said connection enabling said base to rotate relative to said cannula clamp about an axis of the cannula, said connection including an index mechanism with parts interposed between said base and said cannula clamp for retaining said base at incremental relatively rotated positions relative to said cannula clamp.
An apparatus for supporting an endoscope for viewing a surgical site in a patient during surgery on the patient, the endoscope extending through a cannula into the patient, said apparatus comprising:
- a base for supporting the endoscope;
- a cannula clamp including a pair of spaced apart arms for clamping against an outer surface of the cannula through which the endoscope extends;
- and
- an actuator for moving said arms a predetermined distance toward each other to effect clamping against a cannula;
- said cannula clamp further including an adjustment mechanism for changing the relative position of said arms from which said arms are moved by said actuator to enable said arms to clamp different diameter cannulas.
An apparatus for supporting an endoscope for viewing a surgical site in a patient during surgery on the patient, said apparatus comprising:
- a part for engaging the endoscope, said part having a first surface portion for engaging opposed sides of the endoscope and a second surface portion spaced apart from said first surface portion for engaging a part of the endoscope defining a light port.
An apparatus for supporting an endoscope for viewing a surgical site in a patient during surgery on the patient, said apparatus comprising:
- a base for supporting the endoscope;
- a first part adapted to be fixed to the endoscope;
- a second part adapted to be fixed to a cannula with a longitudinal axis;
- and
- a mechanism for axially and rotationally adjusting said first part relative to said second part, said mechanism including a member supported on said base for rotation on said base about an axis parallel to the longitudinal axis of the cannula and spaced from the longitudinal axis of the cannula.
An apparatus for supporting an endoscope for viewing a surgical site in a patient during surgery on the patient, said apparatus comprising:
- a cannula for insertion into a patient, said cannula having a longitudinal axis;
- a cannula clamp for adjustably engaging an outer surface of said cannula;
- a base supported for rotation relative to said cannula clamp about a longitudinal axis of said cannula;
- and
- a part adapted to be fixed to an endoscope, said part being supported for linear movement on said base, the movement of said part being parallel to said longitudinal axis of said cannula.
