Patent number: 12023203Abstract: A force limiting assembly for a surgical instrument that has a handle and a lever pivotally mounted to the handle at a pivot point for movement of an internal drive shaft. The lever is coupled to the drive shaft by a cantilever spring that is positioned within the lever. The free end of the cantilever is spaced apart from the pivot point of the lever and coupled to the drive shaft via stops positioned on the drive shaft on either side of the free end of the cantilever spring. As the lever is pivoting by a user, the forces move the drive shaft and bias the cantilever spring, thereby reducing and ultimately limiting the amount of force that a user may apply to the drive shaft via operation of the lever.Type: GrantFiled: February 6, 2019Date of Patent: July 2, 2024Assignee: Conmed CorporationInventors: Michael Olichney, Mason Williams, Julia Concelman

The rigid handle and the flexible operative end may be joined to each other between a pivot point and a proximal end of the device. The device may form hybrid scissors or hybrid forceps.Type: ApplicationFiled: June 5, 2012Publication date: May 16, 2013Applicant: TRI-MEDICSInventors: Bradley BENDER, Michael SCHULER, Jeffrey I.

Patent number: 8438739Abstract: A scissors includes a pair of scissors constitution bodies which have a cutting portion and a holding portion formed continuously from the cutting portion. The cutting portion has cutter blades formed on both sides in a width direction. The pair of scissors constitution bodies are rotatably joined by a shaft portion in a base end portion of the cutting portion. The pair of scissors constitution bodies cross and rotate in both directions through the shaft portion. The holding portion includes a handle portion mounted therein so as to be visually unrecognized from the outside, the handle portion projected only in one width direction. A slider provided in the holding portion is operated to form a handle portion.Type: GrantFiled: November 24, 2009Date of Patent: May 14, 2013Assignee: Raymay Fujii CorporationInventor: Akio Fujii

Patent number: 8424211Abstract: A pivoting hand tool is provided including handle structures which control the relative angular position of pivotable arms to allow disassembly and reassembly and to prevent accidental disassembly during use. Handle structures includes an elastic interference portion which provides a first interference between the first arm and second arm at the predetermined angle to prevent angular displacement of the arms from exceeding a first predetermined angle until a disassembly pivoting force is applied to the first arm and the second arm.Type: GrantFiled: August 31, 2010Date of Patent: April 23, 2013Assignee: Helen of Troy LimitedInventors: Lucas O Nene, Thomas William Hartman, Evan Mark Abel, Frank J.

Publication number: 20130091713Abstract: A branch scissors structure with an adjustable structure includes a main body and an adjustable structure. One handle of the main body has a wedging opening at a front end near a blade, and a slot is recessedly formed at a bottom wall of the wedging opening. The adjustable structure located corresponding to the wedging opening has a connecting block, a restricting block, a pressing unit and a restricting unit. The position of the restricting block can be adjusted, so that the restricting block can protrude and lean against the outer periphery of the blade through the opening of the connecting block and forms a secure positioning when the restricting unit engages with the restricting slot. The blade can be restricted by the restricting block, and the angle between the handle and blade cab be further limited.Type: ApplicationFiled: October 16, 2011Publication date: April 18, 2013Applicant: JIIN HAUR INDUSTRIAL CO.,LTD.Inventor: Shih-Piao Wu

Patent number: 8393084Abstract: An adjustment device for manual cutting tools is provided. The cutting tool for which the device is intended takes the form of pruning shears having two arms with the respective cutting blades thereof hinged to one another by a transverse bolt forming the main element of the device. A tightened nut for locking the bolt is provided with a transverse hole into which a lateral locking screw is screwed, thereby enabling the hinge to be adjusted. The nut and the locking screw are positioned in a recess in the cutting blade such that the nut cannot rotate when the bolt is being manipulated using a protrusion of the nut housed in a cavity in the cutting blade. The through-hole provided in the cutting blade for the bolt includes a bushing which enables the bolt to be better adjusted in the hole.Type: GrantFiled: January 28, 2008Date of Patent: March 12, 2013Assignee: Bellota Herramientas, S.A.Inventor: José María Azpeitia Urrestarazu

Patent number: 8365417Abstract: A combined scissors and tape dispenser configured as a unitary construction. The combined scissors and tape dispenser apparatus includes a pair of blades. A first blade includes a first elongated cutting member integrated with a first looped handle portion. A second blade is pivotally connected to the first blade. The second blade includes a second elongated cutting member integrated with a second looped handle portion. A dispenser reel including a cutting implement is integrated as part of at least one of the first looped handle portion and the second looped handle portion. The dispenser reel includes a through-hole adapted to be gripped by at least one of the user's fingers.Type: GrantFiled: October 4, 2010Date of Patent: February 5, 2013Assignee: Edison Nation, LLCInventor: Michael Scott Bland

Patent number: 8365418Abstract: A cable tie removal tool for cutting a cable tie off of an underlying structure with which the cable tie is engaged. The tool has an opposed pair of cutting members each having a cutting edge, the cutting members movable between an open position in which the cutting edges are spaced from one another and a cutting position in which the cutting edges are close together or touching. The tool also has a mechanical structure that holds at least one cutting member off of the underlying structure as the cutting members are moved from the open to the cutting position.Type: GrantFiled: June 2, 2006Date of Patent: February 5, 2013Inventors: Kenneth Tomasetti, David A. Hewes

Patent number: 8327548Abstract: A multi-function blade-and-anvil type cutting tool that uses standard type razor blades includes a blade-and-anvil section connected to a first handle portion and a non-tool blade holder and a blade clamp assembly connected to a second handle portion. The standard blades are able to be changed with out tools when the first and second handle portions are moved from a first open position to a second open position to allow the blade holder and the clamp assembly to pivot with one another causing a screw and O-ring latch to move away from a latching slot in the second handle portion. This movement positions the razor blade between the screw and O-ring latch and a blade clamp guide element for easy removal. Each handle portion having a gripping cover disposed thereon. One of the handle portions has a sliding storage tray disposed therein for storing replacement razor blades.Type: GrantFiled: July 17, 2009Date of Patent: December 11, 2012Inventor: John S. Ronan

Patent number: 8266804Abstract: A garden shears includes a pressing member, a holding member, a cutting member and a ratchet. An aperture of the cutting member combines with an aperture of the pressing member for a pivot. The holding member and the ratchet are assembled together at an assembling portion of the pressing member, and teeth of the ratchet engage with a pawl of the cutting member such that the pressing member, the holding member and the ratchet have different pivot points. An opening between the blade and the anvil is smaller than an opening formed between the handle and the holding member. Since the opening formed between the handle and the holding member is larger than the cutting opening between the blade and the anvil, a stronger cutting torque is applied to increase the clipping strength derived from the anvil and the blade.Type: GrantFiled: July 26, 2010Date of Patent: September 18, 2012Assignee: Ho Cheng Garden Tools Co., Ltd.Inventor: Yao-Chung Huang
