Patent Images
1. A surgical instrument holder comprising:
- a coupling collar having a bore extending therethrough and a counterbore defining an inner wall with an annular groove formed therein;
a shaft having an end portion which is insertable through the bore;
quick disconnect means disposed on the shaft end portion for releasably coupling the shaft to the coupling collar by engaging the annular groove formed within the inner wall, the quick disconnect means being compressible and expandable for lockably engaging the coupling collar as the shaft is inserted into the bore, and being disengageable from the coupling collar by applying a compressive force to the disconnect means as the shaft is withdrawn from the bore; and
,clamp means disposed on the shaft for clamping a surgical instrument.

Abstract
A portable console includes a universal positioning arm employing a clamp having quick disconnect means for releasably holding a surgical instrument such as an endoscope during a surgical procedure. The clamp includes a shaft with a bayonet connector disposed thereon, for lockably engaging a collar attached to the positioning arm. The bayonet connector includes flared spring arms which compress and engage the collar for releasably coupling the clamp to the collar.

7. A surgical instrument holding apparatus comprising:
-
a coupling collar defined by a cylindrical body intersected by a bore and a counterbore, the counterbore forming an inner wall and defining a guide surface through the body to a position less than the total length of the cylindrical body, the inner wall having an annular groove formed therein; a shaft having an end portion which is insertable through the bore of said collar; a quick release bayonet connector disposed on the shaft and insertable into the counterbore for lockable engagement with the annular groove, the bayonet connector being releasable in response to an applied compressive force; and a clamp coupled to the shaft for holding a surgical instrument, the clamp being adjustable for accommodating different surgical instrument sizes. - View Dependent Claims (8, 9, 10)
