Abstract
Side bite surgical suturing instruments or portions thereof for endoscopic, laparoscopic, endoluminal, and/or transluminal suturing facilitate the use of larger needles to get a bigger bite while suturing.
Claims20
A surgical suturing instrument, comprising:
- a handle assembly;
- a shaft extending distally from the handle assembly;
- a first jaw member coupled to a distal end portion of the shaft;
- and
- a second jaw member including:
- a proximal end portion coupled to the distal end portion of the shaft;
- and
- a distal end portion movably coupled to the proximal end portion and configured for detachable connection of a curved needle.
5 more elements
A surgical suturing instrument, comprising:
- a shaft defining a longitudinal axis and having a distal end portion;
- an outer tube disposed about the shaft and configured to move axially relative to the shaft;
- a first jaw member including:
- a proximal end portion coupled to the distal end portion of the shaft;
- and
- a distal end portion movably coupled to the proximal end portion of the first jaw member and configured for detachable connection of a curved needle;
- and
- a second jaw member including:
- a proximal end portion coupled to the distal end portion of the shaft;
- and
- a distal end portion movably coupled to the proximal end portion of the second jaw member and configured for detachable connection of the curved needle, wherein the distal end portion of the first jaw member is configured to move relative to the proximal end portion of the first jaw member and the distal end portion of the second jaw member is configured to move relative to the proximal end portion of the second jaw member in response to movement of the outer tube.
8 more elements
An end effector assembly of a surgical suturing instrument, comprising:
- a body portion;
- a first jaw member coupled to the body portion and configured for detachable connection of a needle;
- and
- a second jaw member including:
- a proximal end portion coupled to the body portion;
- and
- a distal end portion coupled to the proximal end portion and configured to move relative to the proximal end portion between a first position, in which a longitudinal axis defined by the distal end portion is disposed at a first angle relative to the proximal end portion, and a second position in which the longitudinal axis of the distal end portion is disposed at a second angle relative to the proximal end portion, the second angle being greater than the first angle, wherein the distal end portion of the second jaw member is configured for detachable connection of the needle.
