| Zusammenfassung: | A retractor assembly (20) for positioning tissue in a surgical arena, such retractor assembly (20) comprising a shaft (310) adapted for longitudinal movement in a clamp channel (42) of non-circular cross-sectional shape wherein the shaft (310) has at least one elongated surface ridge (311) such that the shaft (310) rotates freely within a limited range in said channel (42) for self alignment when contacting tissue and the shaft (310) jams against the channel (42) by interference of said ridge (311) with said channel (42) to automatically limit a range of rotation of the shaft (310). |
