Patent ID: 7887481

Claim:
A surgical retractor device, comprising: a) a mount assembly having opposed upper and lower clamping jaws disposed to receive and grip a mounting rod; b) a clamping mechanism comprising a cam shaft rotatably retained in a cam shaft passage by a shaft pin disposed in the lower clamping jaw a lever, wherein the shaft pin rides in a stop channel in the cam shaft, the stop channel corresponding to rotational movement less than 360° of the cam shaft in the cam shaft passage such that the clamping mechanism provides for selectively moving the upper and lower clamping jaws into and out of a closely spaced relationship, wherein when the cam shaft is actuated to move the clamping jaws into a closely spaced relationship, the mount assembly is capable of gripping a mounting rod received therein and when the cam shaft is actuated to move the clamping jaws into a relatively spaced apart relationship, they are releasable from a mounting rod to allow for repositioning of the clamping mechanism comprising the retractor device along a length of a mounting rod; c) a retractor assembly pivotably supported on the upper clamping jaw of the mount assembly, the retractor assembly comprising: i) a housing having a top surface, a side surface, a bottom surface, and a slot comprising an open channel extending into the top surface and meeting with opposed open ends at the housing side surface; and ii) a retractor mechanism in the retractor assembly housing; and d) wherein a rod receivable in the slot of the retractor assembly housing is releasably engageable by the retractor mechanism to thereby adjust a portion of a rod's length extending beyond the retractor assembly housing.
