Abstract
A tissue stabilizer including an elongated arm, a collet, and a head-link assembly. The collet is disposed at a distal end of the arm. The head-link assembly includes a tube and a spreading mechanism. The tube forms an intermediate section and opposing arms each terminating at a tip. The spreading mechanism can adjust a lateral distance between the tips, and includes first and second articulating members each having a leg and a collet interface body. The first member further includes a female hinge feature, whereas the second member includes a male hinge feature differing from the female hinge feature. The legs of are mounted to discrete regions of the tube, and the male hinge feature is pivotably coupled to the female hinge feature. Automatic spreading of a lateral distance between the tips occurs in response to a compressive force applied to the collet interface bodies.
