Patent number: 5890296Abstract: A cartridge-connecting subassembly for a shaving razor handle including a cartridge connecting structure, a handle connecting structure, and a movable component within the cartridge connecting structure that interacts with a replaceable cartridge when it is connected. The cartridge connecting structure and handle connecting structure have outer side surfaces that mate with inwardly directed surfaces of the cartridge and handle so that the subassembly is substantially covered when it is mounted in the handle and a cartridge is connected. The subassembly has an assembly opening for receiving the movable component during assembly, a cartridge interaction opening through which the component is movable for interaction with the cartridge, and blocking structure that retains the movable component in the subassembly. The movable component is an ejector structure that is separate from the cartridge connecting structure. The subassembly is connected to the handle by staking.Type: GrantFiled: February 12, 1998Date of Patent: April 6, 1999Assignee: The Gillete CompanyInventors: Stephen C. Metcalf, Charles B. Worrick

Patent number: 5616144Abstract: An osteosynthesis plate system is particularly well adapted to securely fuse adjacent cervical vertebrae. The plates are for mounting upon the anterior or posterior surfaces of the vertebrae. Plates for mounting on the anterior vertebral surfaces have a concave bone contacting surface and a bone screw locking mechanism integral with each screw hole. Moreover, the bone contacting surface of the plate has a plurality of bone penetrating protrusions to more securely affix the plate to bone. Plates for mounting on the posterior vertebral surfaces also have bone penetrating protections on their bone contacting surfaces. Such plates are formed so as to have a curved bone contacting surface that is concave in the transverse axis of the plate and convex in the longitudinal axis of the plate. The screw holes of such plates are constructed so as to guide a bone screw along a desired angle to improve the anchoring of the screws in bone.Type: GrantFiled: June 6, 1995Date of Patent: April 1, 1997Assignee: Codman & Shurtleff, Inc.Inventors: Ronald A. Yapp, Charles B. Worrick, III

Patent number: 5207692Abstract: A surgical clip applier includes a pair of pivotal housing sections on which are provided a pair of clip actuating jaws. An elongated clip sleeve which receives a plurality of surgical clips arranged front to back in a row is mounted for longitudinal reciprocating movement between the housing sections. The clip sleeve includes a pair of clip retaining jaws adjacent to its open front to receive and hold a surgical clip advanced from the clip sleeve between the clip actuating jaws on the housing sections. A pusher is mounted on the clip sleeve for engaging the rearmost clip in the row. The surgical clip applier includes a ratchet mechanism which is operable each time the clip sleeve is reciprocated to advance the pusher and the row of clips by one step corresponding to the length of one surgical clip in the row. The ratchet mechanism includes a first ratchet on the clip sleeve and a second ratchet on one of the housing sections which are engaged by pawls on opposite sides of the pusher.Type: GrantFiled: July 30, 1990Date of Patent: May 4, 1993Assignee: Codman & Shurtleff, Inc.Inventors: Robert G.

Patent number: 4990148Abstract: A rongeur with special features applied to the footplate area to prevent the intersection of stress fields to allow the rongeur to be reduced in size and mass without materially reducing the strength of the rongeur. A transverse groove is used at the intersection of the anvil surface of the base plate and the shank base plane. Also the base of the footplate recess is offset from the shank base plane and the inside wall of the recess meets the recess base in a gentle curve. These features can be used individually or together to prevent the intersection of stress fields in the footplate area and thus allow the size of the footplate to be reduced without materially reducing the strength of the rongeur.Type: GrantFiled: January 13, 1989Date of Patent: February 5, 1991Assignee: Codman & Shurtleff, Inc.Inventors: Charles B. Worrick, III, John A. Santangelo

Patent number: 4961743Abstract: A torsion spring with a coil portion having extensions extending from the ends of the coil for receiving forces for torquing the spring. The spring provides a more balanced stress distribution about the coil which in the preferred embodiment include a region of increased cross-sectional area on one side of the coil and a region of decreased cross-sectional area across the coil from the region of increased cross-sectional area and smooth contouring of the coil between these two regions. A particular use of the torsion spring of the present invention is in a torsion spring-type aneurysm clip for providing more uniform stress distributions about the coil portion of the aneurysm clip and for permitting the aneursym clip to open wider so that it may be used on larger aneurysms.Type: GrantFiled: January 3, 1989Date of Patent: October 9, 1990Assignee: Codman & Shurtleff, Inc.Inventors: George Kees, Jr., Charles B. Worrick, III, John A. Santangelo

Patent number: 4604089Abstract: A pressure regulated system for an irrigation system including a reservoir of irrigation fluid, a pump, catheters for providing access to and egress from the irrigation site and a pressure regulation circuit, all connected in series with one another. The pressure regulation circuit includes a flow restriction branch having a normally-open valve and a variable orifice, diaphragm-operated, restrictor and a pressure accumulation branch, having a check valve, accumulator, and a normally-closed valve. A conduit running from the pressure accumulation branch to the diaphragm controls the pressure regulator. The operator may raise the pressure by closing the normally-open valve to direct pump flow to the pressure accumulation branch and thereby restrict the orifice of the pressure regulator until the desired pressure has been reached, and then releases the valve to maintain that pressure.Type: GrantFiled: August 15, 1983Date of Patent: August 5, 1986Assignee: Codman & Shurtleff, Inc.Inventors: John A. Santangelo, Charles B. Worrick, III
