US Patent:

58938753, Apr 13, 1999

Filed:

May 15, 1997

Appl. No.:

8/856938

Inventors:

Paul D. O'Connor - East Bridgewater MA
Christopher M. Batchelder - Wells ME
Giuseppe Lombardo - Bridgewater MA

Assignee:

TNCO, Inc. - Whitman MA

International Classification:

A61B 1728
A61B 1732

US Classification:

606205

Abstract:

A detachable and replaceable end effector assembly. The detachable mechanism is made of standard end effectors attached to an actuating tip and pinned inside a yoke assembly. Replacement is made by pulling back a spring loaded radial lock 90, to disengage two rear tabs 51 on the outer tip 50. The yoke assembly is then rotated 90 degrees to disengage the rear yoke pin 9 from the tubular shaft 70. This rotation of 90 degrees also unlocks the T-bar 45 from the front "T" slot of the long actuator 80. The end effector or jaw assembly is then free to be pulled away from the remainder of the shaft. In addition there is a bayonet connection to hold the parts together and prevent accidental disconnection.

International Classification:

A61B 17/16

US Classification:

606 83

Abstract:

A microfracture pick having features configured to aid a user in advancing the microfracture pick through bone. The microfracture pick has an elongated member with a proximal end, a distal end, a sharp, optionally angled tip disposed adjacent the distal end of the elongated member, and at least one engaging feature disposed at one or more locations on the elongated member for engaging a complementary feature of a strike instrument. By striking an impact surface of the strike instrument, the user can produce a force that is translated via the elongated member of the microfracture pick through the tip, thereby making penetration of the tip through the bone more effective.
