US 11,627,952 B2 · Surgical retractor

Abstract

In one aspect, a surgical retractor having sliders configured to have tissue engaging members connected thereto and slider drives including operating members. The operating members are rotatable to cause the slider drives to shift the sliders relative to one another. The surgical retractor includes a coupler having a coupling configuration wherein the coupler connects the slider drives and rotation of one of the operating members causes movement of the sliders. The coupler also has a decoupling configuration wherein the coupler disconnects the slider drives and rotation of the one operating member causes movement of fewer sliders than the sliders that are moved with the coupler in the coupling configuration. The retractor has an actuator connected to the coupler and movable between a dependent slider movement position and an independent slider movement position to shift the coupler between the coupling configuration and the decoupling configuration.

Dependent claims

A surgical retractor comprising:

sliders configured to have tissue engaging members connected thereto;
slider drives including operating members, the operating members rotatable to cause the slider drives to shift the sliders relative to one another;
a coupler having a coupling configuration wherein the coupler connects the slider drives and rotation of one of the operating members causes movement of the sliders, the coupler having a decoupling configuration wherein the coupler disconnects the slider drives and rotation of the one operating member causes movement of fewer sliders than the sliders that are moved with the coupler in the coupling configuration;
and
an actuator connected to the coupler and movable between a dependent slider movement position and an independent slider movement position to shift the coupler between the coupling configuration and the decoupling configuration.

2 more elements

A retractor system comprising:

a retractor;
a tissue engaging member assembly having a proximal end portion to connect to the retractor and a distal end portion;
a bone screw having a head portion and a threaded shank portion for engaging a bone, the head portion having a rotary drive structure;
an adapter of the tissue engaging member assembly configured for being secured to the bone screw, the adapter comprising:
a body having an interior to receive the head portion of the bone screw, the body having a body thread and a central longitudinal axis;
an opening of the body sized to permit the body and the bone screw head to be shifted laterally relative to one another to advance the bone screw head portion through the opening of the body and into the interior of the body;
and
a locking member having a locking member thread configured to engage the body thread and a locking member rotary drive structure to receive a driver for turning the locking member, the locking member rotatable by the driver in a first direction to shift the locking member along the central longitudinal axis of the body via engagement of the body thread and the locking member thread from an unlocked position wherein the locking member permits the locking member and body to pivot relative to the bone screw to a locked position wherein the locking member clamps the bone screw head between the locking member and the body to fix the locking member and body against pivoting relative to the bone screw.

5 more elements

A surgical retractor comprising:

a base frame having a portion to be secured to a support structure;
a first slider to receive a first tissue engaging member;
a first slider drive operable to shift the first slider between extended and retracted positions relative to the base frame;
an intermediate frame;
a frame slide connection between the base frame and intermediate frame;
second and third sliders on opposite sides of the first slider to receive second and third tissue engaging members, the second and third sliders including bodies, arms, and pivot connections between the bodies and the arms;
wherein the pivot connections between the bodies and the arms are onboard the intermediate frame;
slide connections between the bodies of the second and third slider and the intermediate frame;
second and third slider drives operable to shift the second and third sliders longitudinally between extended and retracted positions relative to the intermediate frame;
the arms of the second and third sliders extending laterally outward from the intermediate frame to position the second and third tissue engaging members laterally offset and spaced from the intermediate frame;
and
an intermediate frame drive operable to shift the intermediate frame and the second and third sliders connected thereto relative to the base frame to facilitate positioning of the second and third sliders independent of the first slider.
