Abstract

The present disclosure describes systems and methods for selectively constraining an orientation of a portion of a surgical tool system relative to another. Example surgical tool systems may include a surgical tool having at least one movable component, at least one actuation component, and a surgical tool attachment. The surgical tool attachment may be operable selectively to engage and disengage the moveable component so as to prevent movement of the movable component relative to the surgical tool in an engaged configuration and to permit movement of the movable component relative to the surgical to in a disengaged configuration, respectively. In the engaged configuration, a dynamic component of the surgical tool system may be fixed relative to the surgical tool, and, in a disengaged configuration, the dynamic component may be freely movable relative to the surgical tool.

First claim

What is claimed is:

1. A surgical tool system comprising:
a surgical tool comprising:
a handle portion configured to be grasped by a hand of a user;
a ventilation passage formed in the surgical tool;
at least one movable component; and
at least one actuation component; and

a surgical tool attachment configured to be coupled to the surgical tool, the surgical tool attachment comprising:
a body comprising:
a tab extending from a first end of the body and operable to interfere with the at least one movable component of the surgical tool;
a cavity extending longitudinally through the body and configured to slidably receive the surgical tool, wherein the cavity comprises a non-round cross-sectional shape that corresponds to a complimentary non-round cross-sectional shape of the surgical tool; and
a slot extending radially outwards from the cavity through an entirety of a side of the body and extending at least partially along a length of the body so as to not interfere with the at least one actuation component of the surgical tool;
wherein the surgical tool attachment further comprises an aperture formed in the body and extending from the cavity to an exterior of the body, wherein the aperture aligns with the ventilation passage to prevent positive or negative pressure between the surgical tool attachment and the surgical tool when the surgical tool attachment is being attached and/or removed from the surgical tool.

2. The surgical tool system of claim 1 , wherein the surgical tool attachment is integrated into the surgical tool.

3. The surgical tool system of claim 1 , wherein the tab is disposed on an outer edge of the body.

4. The surgical tool system of claim 1 , wherein the cross-sectional shape of the cavity is hexagonal.

5. The surgical tool system of claim 1 , wherein the surgical tool attachment further comprises at least one depression formed in an exterior surface of the body, the exterior surface of the body forming an ergonomic gripping surface to the hand of the user.

6. The surgical tool system of claim 1 , wherein the at least one movable component comprises a plurality of notches, and
wherein the tab comprises a cross-sectional shape that corresponds to a cross-sectional shape of the notches, and
wherein the tab is configured to be insertable into at least one of the notches so as to secure the at least one movable component in an orientation with respect to the surgical tool.

7. The surgical tool system of claim 1 , wherein the at least one movable component comprises a plurality of raised portions,
wherein the tab has a cross-sectional shape that defines a channel that is configured to receive at least one of the raised portions of the at least one movable components so as to secure the at least one movable component in an orientation with respect to the surgical tool.
