Patent number: 11779368Abstract: 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: GrantFiled: September 1, 2021Date of Patent: October 10, 2023Assignee: BEAVER-VISITEC INTERNATIONAL (US), INC.Inventors: Dana Cote, Brian Rapp, Paul Karnafel, Xiaoyu Zhang

Patent number: 11389150Abstract: In a first aspect of the subject invention, an iris expander is provided which includes a non-metallic, unitary, multi-segmented body which is expandable from a first state to a second state. The second state defines a larger footprint than the first state with the body being defined by a plurality of segments connected by living hinges. In a further aspect, an iris expander is provided which includes a multi-segmented body that is expandable from a first state to a larger-footprint second state. At least one aperture is formed in the body with a channel extending therefrom embedded in the body such that no portion thereof is exposed externally of the body. The channel is formed to accommodate a portion of an instrument for causing adjustment of the body with avoidance of direct contact of the instrument with the tissue of the iris.Type: GrantFiled: September 10, 2019Date of Patent: July 19, 2022Assignee: BEAVER-VISITEC INTERNATIONAL (US), INC.Inventors: Dana M.

Patent number: 11096823Abstract: An ophthalmic marking device is provided herein for marking a patient's eye. The device may include a handle and a tip with a tip element, a first portion of the tip element protruding from the tip to be exposed. The tip element is electrically conductive to resistively generate heat with electrical flow therethrough. A source of electrical power is associated with the device and electrically coupled to the tip element. The source of the electrical power and the tip element are configured to cause the first portion of the tip element to have a temperature in a range of 250° F.-450° F. Advantageously, the subject invention provides for a relatively low-cost device for marking a patient's eye and allows for creating a less traumatic marking on a patient's eye as compared to higher temperature electrocautery devices.Type: GrantFiled: January 17, 2017Date of Patent: August 24, 2021Assignee: Beaver-Visitec International (US), Inc.Inventors: Robert H.

Patent number: 10117703Abstract: In one aspect, a method is provided herein of marking a patient's eye for reference during a toric lens implantation procedure. The method includes providing an electrocautery device having a handle, a shaft extending from the handle, and a tip defined at the terminus of the shaft. The handle is elongated and extends along a longitudinal axis with the shaft being bent or curved such that the tip is spaced from, and not aligned with, the longitudinal axis. The method further includes using the electrocautery device to cauterize one or more points on the patient's eye, the points being located as reference marks for placement of the toric lens. Advantageously, with the subject invention, a device is used having a bent or curved shaft which may better accommodate the curvature of a patient's eye while marking.Type: GrantFiled: October 17, 2012Date of Patent: November 6, 2018Assignee: BEAVER-VISITEC INTERNATIONAL (US), INC.Inventors: Robert H.

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: 9044265Abstract: A retractable safety knife has a hollow handle with an opening at an end thereof, a pusher that is movably disposed within the handle and is operable by a user, and a blade that is connected with an end of the pusher. When the pusher moves from a blade-retracted position to a blade-extended position, the blade extends outwardly from the handle opening and rotates from a nested position to an extended position.Type: GrantFiled: December 22, 2010Date of Patent: June 2, 2015Assignee: Beaver-Visitec International (US), Inc.Inventor: Dana Michael Cote

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.
