Filed:

Apr 28, 1994

Appl. No.:

8/233900

Inventors:

Rene J. Cabrera - Stoughton MA
John R. Bookwalter - Brattleboro VT
Joseph L. Chaudoin - Wrentham MA

Assignee:

Johnson & Johnson Professional, Inc. - Raynham MA

International Classification:

A61B 1702
A61B 1756

US Classification:

600201

Abstract:

A retractor blade having a generally "S" shaped configuration in cross section. The blade is pivotally attached to a rod which may be connected to a table fixed ring retractor. The central portion of the blade moves tissue away from the operative site when the distal end of the blade is placed against a bone and the rod is moved away from the operative site.

International Classification:

A61B 1702

International Classification:

G05G 100
A61B 1702

US Classification:

74577M

Abstract:

A multi-position ratchet mechanism for holding a surgical retractor blade which permits a retractor blade to be rotated into the wound and retracted at the same time to duplicate the natural "toe-in" method of retraction achieved with the hand. The ratchet mechanism includes a ratchet holder to which is pivotally attached a ratchet pivot housing. The retractor blade is mounted in an opening projecting through ratchet pivot housing and held in position by a retractor pawl attached to the ratchet pivot housing. The ratchet pivot housing also has a curved ratchet which depends into a cooperating slot in the ratchet holder and engages a ratchet release bar which is mounted on the ratchet holder and spring biased into the ratchet slot. One end of ratchet release bar is positioned under an actuating surface of the retractor pawl. The application of pressure on the actuating surface will release both ratchets to allow adjustment of the retractor blade.

Thomas W. Eager - Belmont MA

Assignee:

Codman & Shurtleff, Inc. - Randolph MA

International Classification:

A61B 1736

US Classification:

1283031

Abstract:

A surgical tool for intercepting laser energy after it has energized a target site but before it energizes adjacent tissue. The instrument includes substrate of material having a high thermal conductivity for transmitting laser energy away from the surgical site and a highly absorbent surface material for absorbing radiant energy at the wavelength of the incident laser.
