Surgical instrument attachment system
First Claim
1. A surgical implement for use with a hand-piece of a surgical instrument for performing a surgical treatment to a human or animal body, the surgical implement comprising:
- an outer tube member including an outer hub and an outer tube extending longitudinally from the outer hub, the outer tube and the outer hub defining a longitudinal bore, the outer hub including a circumferentially extending locking groove and an engaging element respectively disposed at an outer surface of the outer hub and configured for releasable attachment of the outer tube member to a corresponding member of the surgical instrument, a proximal end portion of the outer hub having an enlarged bore coaxial with the longitudinal bore of the outer tube and the outer hub; and
an inner tube member including an inner hub and an inner tube extending longitudinally from the inner hub, the inner tube and the inner hub defining a longitudinal bore, the inner tube configured to insert within the longitudinal bore of the outer tube member and including an effect portion for performing a surgical treatment there-about, the inner hub including a connection element configured for detachably connecting to an actuator of the surgical instrument for performing a the surgical treatment, a distal end portion of the inner hub configured to be rotatably received within the enlarged bore of the outer hub.

Abstract
A surgical implement for use with a hand-piece of a surgical instrument for performing a surgical treatment, comprises: an outer tube member including an outer hub and an outer tube extending longitudinally from the outer hub, the outer tube and the outer hub defining a longitudinal bore, the outer hub having a generally circular outer surface and including a circumferential locking groove and a key for releasable attachment of the outer tube member to the surgical instrument; and, an inner tube member including an inner hub and an inner tube extending longitudinally from the inner hub, the inner tube and the inner hub defining a longitudinal bore, the inner tube configured to insert within the longitudinal bore of the outer tube member and including an end effect portion disposed adjacent to a distal end of the inner tube, the inner hub having a generally circular outer surface and including a plurality of bosses radially formed on the outer surface thereof for releasably connecting the inner tube member to an actuator of the surgical instrument for performing the surgical treatment. A surgical instrument having a coupling for releasable attachment of the surgical implement is also disclosed.

13. A surgical Instrument for performing a surgical treatment, comprising:
-
a surgical implement including an elongate outer tube member and an elongate inner tube member, the outer tuber member defining a longitudinal bore, the outer tube member including a distal outer tube and a proximal outer hub, the outer hub having a circumferential locking groove and an engaging element at an outer circumference thereof, a proximal end portion of the outer hub having an enlarged bore coaxial with the longitudinal bore of the outer tube and the outer hub, the inner tuber member defining another longitudinal bore, the inner tube member including a distal inner tube and a proximal inner hub, the inner hub having a connection element, a distal end portion of the inner hub configured to be rotatably received within the enlarged bore of the outer hub, the inner tube of the inner tube member configured to slidably insert within the longitudinal bore of the outer tube member;
a hand-piece including an actuator, and a coupling for attaching the surgical implement to the hand-piece;
wherein the coupling includes a generally cylindrical coupler, the coupler having a longitudinal opening configured to receive a proximal portion of the surgical implement therein and at least one circumferential hole formed through the cylindrical coupler in a radial direction, the coupler further having a counterpart engaging element connectable with the engaging element of the outer hub for attachment of the surgical implement to the hand-piece, the coupling further includes at least one locking ball slidably received within the circumferential hole of the coupler, and an outer slider having a longitudinal opening for receiving the coupler therein, the outer slider including a circumferential inner recess and being moveable along the coupler between a lock position where the locking ball is pushed radially by the outer slider for engaging with the circumferential locking groove of the outer hub of the surgical implement for connection of the surgical implement to the coupling of the hand-piece and an unlock position where the locking ball is at least partially retrieved into the circumferential recess of the outer slider for allowing detachment of the surgical implement from the coupling of the hand-piece; and
wherein a distal end of the actuator includes a counterpart connection element for connecting with the connection element of the inner hub of the surgical implement for performing a surgical treatment. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
