  • Patent number: 10870213
    Abstract: A utility instrument is in the form of a cutting tool suitable for fitting onto a user's finger. The tool has a blade and a sheath, both coupled to a mounting structure. The blade and sheath are pivotable with respect to each other. A user can wear the tool on a finger about a finger joint. The user can bend the finger to set the tool to an open condition to expose the blade for use, and can stretching the finger to set the tool to a closed condition to safely shade the blade using the sheath. The tool may further have a housing for fully receiving the blade. The blade may extend out of the housing for use, and may be retracted into the housing for safety.

  • Patent number: 9855035
    Abstract: This disclosure includes needle holders and related methods. Some holders use or include an elongated handle having a proximal portion and a distal portion, a first jaw member coupled to the distal portion of the handle, a second jaw member pivotally coupled to the first jaw member, and a lever pivotally coupled to the handle and coupled to the second jaw member such that the lever can be actuated by a user's thumb to selectively open and close the jaw members. In some holders, the handle extends proximally beyond the lever such that the lever can be actuated by the user's thumb to selectively open and close the jaw members while the handle is grasped within the user's hand. In some holders, the handle is defined by an elongated housing defining an interior volume configured to receive at least a portion of the lever when the jaw members are closed.

  • Patent number: 9724835
    Abstract: A pair of scissors has a first cutting blade with a thumb handle and a thumb ring and a second cutting blade with a finger ring. The second cutting blade is pivotally attached to the first cutting blade, and the first and second cutting blades pivot relative to one another within a first plane. The thumb ring is slidably attached to the first cutting blade by a shaft that moves freely but with a certain amount of friction along a longitudinal slot in the thumb handle of the first cutting blade when the scissors are in use. The longitudinal slot in the thumb handle is situated within a second plane that is perpendicular to the first plane.

  • Patent number: 9549771
    Abstract: The present invention provides a fingerstall-cannulated guide device for accurate and efficient guide wire placement for antegrade femoral nailing systems. The said device comprises a fingerstall with a cannulated guide connected with or without a threaded guide wire. Using this device, surgeons can determine the entry point for the guide wire fast and accurately by tactile hand-eye coordination. After correct entry point is obtained, the guide wire is advanced and the fingerstall-cannulated guide can be easily detached. The device and method can accomplish the following: (1) reduction of the surgery time; (2) reduction of the radiation exposure times, and (3) reduction of the soft tissue damage during surgery. The device is also beneficial for use in fastening together any or all portions of bone surrounding a fracture site.

  • Patent number: 8726522
    Abstract: A pair of scissors with an open second handle includes a first blade and a second blade pivotally connected by a pivot member. A first grip portion of the first handle surrounds the basal portion of a user's thumb, the thumb extends out of an inserting hole of the first blade in a lateral direction and presses against a first extension section, so that the user can hold the first grip portion with the thumb without bending too much at the wrist, thus enhancing stability of holding the scissors. The user's middle, ring and little fingers press against the grip section of the second handle, and the index finger rests against the second extension section. Besides, since the second grip portion is an open structure, the fingers of the user are supported but not restricted by the second grip portion, which improves stability and flexibility when using the scissors.

  • Patent number: 8555512
    Abstract: Each of handles of a pair of scissors includes a hard core member and a soft member softer than the core member and including a contact face portion with which a finger of a user comes in contact, a bottomed recessed hole portion adjacent to the contact face portion and thinner than portions around it, and a through hole portion continuous with the bottomed recessed hole portion. When the user inserts and removes his/her fingers into and from finger rings, the contact face portions escape while compressing the through hole portions and the contact face portions tilt by using the bottomed recessed hole portions as fulcrums. Moreover, the bottomed recessed hole portions and the through hole portions continuous with each other are molded, which allows an elastic deformation property and a shape retaining property of the contact face portions to go together and also contributes to durability of the soft members including the contact face portions.

    Abstract: A scissor has a finger hole mechanism mounted on the side of one of the scissor handles. The finger hole mechanism may allow the scissor to be worn, rather than gripped. When the scissor is not in use, the scissor remains on the finger—yet allows the use of all fingers for other tasks. To resume use, only the thumb is needed to press the scissor closed—as it no longer needs to be held, merely used when needed.

    Abstract: The present invention has been accomplished to provide cost effective scissor sizer devices that can be used to adjust the size of finger openings on scissors. The sizer may be of a pre-determined size or may be malleable so as to conform to the shape of the scissor handle opening to provide a more secure fit of the sizer with the handle. The sizer may be smooth on its inner surface or may have rough areas on its inner surface in order to help prevent the fingers of the user from slipping within the handle openings. The sizer may be secured to the scissor handle openings by various means. Means of attachment include use of bendable tabs capable of being bent to grasp and fit to the handle opening. The sizer may also be attached using screws to secure the sizer to the handle opening. The sizer may also contain a ratchet mechanism to secure the sizer to the handle. Further, the sizer may be permanently affixed, by glue or some other means of permanent attachment, to the handle opening.

    Abstract: The present invention relates to a new type of scissors for hairstylist which allows the hairstylist to optimise the cutting operations, in particular by eliminating the need to go over the tip of the locks of hair with the tip of the straight scissors or to go over the locks of hair with trimming scissors in order to move the edge of the lock of hair, which is straight when the lock of hair is cut using the straight scissors or other similar known models of the prior art. Instead, the scissors according to the present invention allows in a single cutting operation to obtain a “perfectly irregular” end of the lock of hair, obtaining an irregular line of perfect measure and combining the gripping comfort and the manageability of the scissors for hairstylists with the efficacy of a tool capable of obtaining a non-straight cut of the lock of hair, conferring in this manner a greater comfort of use and a greater efficacy to the scissors.

The distal end parts (4a, 5a) of the blades (4, 5) form a heart-shaped contour form C in a state in which the blades (4, 5) are closed and the cutting blades (2, 3) are brought together. Even while the children's scissors (1) are open, there is no danger of an injury being caused by a sharp corner of the cutting blades becoming exposed and a finger tip or other body part coming into contact with the cutting blades, which is a problem in conventional scissors, and safety is achieved.
