Abstract

A surgical retractor and a method of minimally invasive surgery, wherein the surgical retractor includes ribs and a mechanism for microns-resolution transferring of linear and rotational movements of the ribs and wherein each rib can be easily replaced without use of any additional tools. According to an embodiment of the present invention the transmission is simpler. Likewise, an auxiliary handle is added to facilitate the insertion of the ribs into the body of the operated patient, and the vast majority of components of the surgical retractor are made with biocompatible, and FDA approved material ULTEM HU 1000 RESIN transparent (radiolucent) to X-ray radiation and are designated for single use.

Claims16

Dependent claims

A surgical retractor comprising:

(a) a ribs assembly, said ribs assembly including at least two ribs;
(b) a mechanism for transferring of radial linear and rotational movement adapted to apply mechanical forces and moments to said ribs assembly;
(c) a casing, said casing including:
(i) a channeled disc wherein said mechanism for transferring of linear and rotational movement and said ribs assembly are mounted on said channeled disc;
and
(ii) a cover disc, wherein said cover disc is connected to said channeled disc;
(d) a grooved disc mounted inside said casing, wherein said grooved disc has a grooved disc body, wherein in said grooved disc body, there are a grooved disc central perforation and at least two curved grooves, and wherein said grooved disc has grooved disc teeth on a grooved disc outer surface;
and
(e) a transmission, for granting rotational movement to said grooved disc, said transmission being mounted on said casing, wherein said transmission includes:
(i) a transmission first cog wheel;
and
(ii) a transmission bolt head mechanically connected to said transmission first cog wheel,
wherein said transmission first cog wheel is engaged with said grooved disc teeth.
