Abstract

A surgical device includes a housing and a hollow shaft extending from the housing. The hollow shaft includes one or more drive shafts disposed within the hollow shaft. Each drive shaft is detachably coupled to a surgical instrument and is operable to control moving parts on the surgical instrument. A method for performing a surgical procedure includes the steps of inserting a hollow shaft containing one or more drive shafts into the body via a first orifice; inserting a surgical instrument into the body via a second orifice, the surgical instrument being configured to couple with the hollow shaft to connect the surgical instrument with one or more drive shafts; and coupling the hollow shaft and the surgical instrument after the hollow shaft and surgical instrument are inserted into the body.

Dependent claims

A method for performing a procedure on a body, comprising the steps of:

(a) providing a hollow shaft having a proximal end and a distal free end without any surgical instrument supported on the distal free end, the hollow shaft having a diameter and containing a drive shaft rotatably disposed therein, the distal free end of the hollow shaft configured to permit a surgical instrument to be mounted to the distal free end of the hollow shaft;
(b) inserting the distal free end of the hollow shaft without any surgical instrument attached thereto in the body via a first body orifice;
(c) inserting a surgical instrument into the body via a second body orifice, the surgical instrument including a coupling complimentary to and configured to couple with the distal free end of said hollow shaft to connect the drive shaft with the surgical instrument in operable communication;
and
(d) coupling the hollow shaft and the surgical instrument via the coupling to mount the surgical instrument to the distal end of the hollow shaft after the steps of inserting the hollow shaft and inserting the surgical instrument.
