Abstract: A surgical instrument includes first and second shaft members defining proximal and distal end portions and including handles at the proximal end portions thereof. A pivot member couples the distal end portions with a gap defined therebetween proximally of the pivot member. First and second jaw members extend distally from the shaft members, distally of the pivot member. A lockout bar is movable between an unlocked position, withdrawn from the gap, and a locked position, disposed within the gap. The handles are pivotable between spaced-apart and approximated positions to pivot the jaw members between open and closed positions. The handles are yawable between the approximated position and a yawed position to yaw the jaw members between the closed position and a cutting position. The gap provides clearance to permit yawing such that, when the lockout bar is disposed in the locked position, yawing of the handles is inhibited.

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.

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.

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: 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.
