Abstract

Surgical tools that can be used in single port laparoscopic procedures can include a low-profile handle assembly to minimize tool interference adjacent the incision site. For example, a handle assembly for a surgical instrument can have a generally in-line configuration extending linearly along a central longitudinal axis of an elongate shaft of the instrument. A linkage mechanism including a trigger, an actuation link, and an actuation shaft can be positioned within the in-line handle. The linkage mechanism can be pivoted between an open position in which end effectors of the instrument are open and a toggle position in which the end effectors are locked closed. A locking mechanism such as a ratchet mechanism can also be used to lock the end effectors. A surgical dissector can include gripping jaws having a curved profile or an angled elongate shaft to minimize tool interference and maximize visibility within a procedure site.

Claims13

Dependent claims

A surgical instrument comprising:

a handle assembly having a proximal end and a distal end;
an elongate shaft extending from the distal end of the handle assembly along a central longitudinal axis, the elongate shaft having a distal end opposite the handle assembly;
and
an end effector assembly disposed at the distal end of the elongate shaft;
wherein the handle assembly further comprises:
a handle body comprising an exterior surface, a first aperture formed in the exterior surface and a second aperture formed in the exterior surface and diametrically opposed to the first aperture;
and
a linkage mechanism comprising:
a trigger pivotably coupled to the handle body near the distal end of the handle assembly, the trigger comprising a first end extendable from the first aperture and a second end extendable from the second aperture, the trigger being pivotable between an open position in which the first end extends from the first aperture and the end effector assembly is in an open state, and a closed position in which the second end extends from the second aperture and the end effector assembly is in a closed state;
an actuation link pivotably coupled to the trigger between the first end and the second end and extending generally proximally within the handle body;
an actuation shaft pivotably coupled to the actuation link proximal of the coupling of the actuation link with the trigger, the actuation shaft being longitudinally slidable with respect to the elongate shaft responsive to pivotal movement of the trigger;
and
a ratchet mechanism to selectively latch the trigger to the handle body.

A surgical instrument comprising:

a handle assembly having a proximal end and a distal end;
an elongate shaft extending from the distal end of the handle assembly along a central longitudinal axis, the elongate shaft having a distal end opposite the handle assembly;
and
an end effector assembly disposed at the distal end of the elongate shaft;
wherein the handle assembly extends generally linearly from the proximal end to the distal end thereof;
and wherein the handle assembly further comprises:
a handle body having an outer surface and comprising a first aperture in the outer surface and a second aperture in the outer surface opposite the first aperture;
and
a linkage mechanism comprising:
a shuttle pivotably coupled to the handle body near the distal end of the handle assembly and extending across the handle body between the first aperture and the second aperture, the shuttle comprising a first surface extendable from the first aperture of the handle body and a second surface extendable from the second aperture and pivotable between a first position in which the first surface protrudes from the first aperture and a second position in which the second surface protrudes from the second aperture, wherein movement of the shuttle between the first position and the second position actuates the end effector assembly;
and
a ratchet mechanism to selectively lock the shuttle to the handle body.
