Publication number: 20240023986Abstract: A surgical knife safety device having a handle, a blade connected to the handle, and a guard carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard radius is provided at the distal end of the handle to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder, preventing unwanted blade or handle movement due to guard mechanism tolerances. A spring, such as leaf spring or a cantilever beam, and a pair of detents or slots are provided to fix the guard in the extended or retracted position and to provide resistance during movement between the two positions.Type: ApplicationFiled: September 27, 2023Publication date: January 25, 2024Inventors: Dana Cote, Brian Rapp, Paul Karnafel, Xiaoyu Zhang

Publication number: 20220054740Abstract: A fluid delivery device has a syringe barrel-type reservoir with plunger and plunger driver assembly comprising nested, telescopic screws comprising an innermost screw keyed to a first side of the plunger or intermediate pusher to prevent rotation. In a fully retracted position, the nested screws do not extend into the reservoir. The nested screws all have right handed threads and employ the same pitch in their respective inner thread and outer thread designs. The outermost screw is connected to a motor for controllable rotation. The decreasing torque ratios from the outermost to innermost screw member and anti-rotation feature allows the innermost screw to advance the plunger into the reservoir before the adjacent concentric screw member commences rotating and advancing within its corresponding screw, and so on, to translate the plunger and expel fluid in a fluid chamber defined on the other, second side of the plunger.Type: ApplicationFiled: August 13, 2021Publication date: February 24, 2022Inventors: Mark WOOD, Dana COTE, Alessandro PIZZOCHERO

Patent number: 9095322Abstract: A speculum is provided herein which includes first and second arms, connected by a hinge, each having a channel formed thereon adapted to the shape of an eyelid. First and second elements are respectively located on the first and second arms configured to cooperatively retain the first and second arms in select rotational positions. A slot is defined in the second arm to partially separate first and second portions of the second arm with the first portion being displaceable away from the second portion. The second element is located on the first portion. Advantageously, with this arrangement, the first portion acts as a spring-loaded hinge which applies not only biasing force to the second element for retention, but also permits the second element to be separable from the first element. The subject invention provides a mechanical feature beyond the inherent memory of the material for operation of the speculum.Type: GrantFiled: September 21, 2011Date of Patent: August 4, 2015Assignee: Beaver-Visitec International (US), Inc.Inventors: Frederick M.

Patent number: 8757378Abstract: A package for a surgical blade tip is provided herein. The package cooperates with the surgical blade tip to properly retain it and facilitate mounting onto a surgical blade handle. In one aspect, the invention includes a package having a body with a side wall and at least two detents extending inwardly from the side wall. In addition, a surgical blade tip is provided having an adaptor with a blade extending therefrom. The adaptor includes at least two recesses formed therein. The surgical blade tip is disposed in the package with the detents being at least partially inserted into the recesses. Also, the detents are configured to apply a retentive force to the adaptor to retain the adaptor in a first position and configured to deflect with a predetermined amount of torque being applied to the surgical blade tip so as to permit the adaptor to rotate from the first position to a second position where the detents are not inserted into the recesses.Type: GrantFiled: March 31, 2010Date of Patent: June 24, 2014Assignee: Beaver-Visitec International (US), Inc.Inventors: Dana Cote, Robert DeMarinis, Gregory P.

Publication number: 20140155700Abstract: In one aspect, a speculum is provided herein which includes a first arm having a first channel formed thereon adapted to the shape of an eyelid; a second arm having a second channel formed thereon adapted to the shape of an eyelid; a hinge unitarily formed with the first and second arms, the hinge permitting the first and second arms to selectively rotate about an axis rotation, the selective rotation causing the first and second channels to selectively move closer and farther apart; and, a position retaining arrangement. The position retaining arrangement includes a first element formed unitarily with the first arm, and a second element formed unitarily with the second arm. The first and second elements are configured to cooperatively retain the first and second arms in a selected rotational position. Advantageously, a unitary speculum may be formed which includes an adjustable position retaining arrangement.Type: ApplicationFiled: February 4, 2014Publication date: June 5, 2014Applicant: BEAVER-VISITEC INTERNATIONAL (US), INC.Inventors: FREDERICK M.
