摘要： PROBLEM TO BE SOLVED: To mutually independently rotate a first trigger and a second trigger by arresting the rotation of the second trigger until the first trigger moves a shooting conducting assembly to a remote position. SOLUTION: A shooting conducting assembly has a shooting bar 43 extended from a frame to the surgical fixing assembly of an end effector, the shooting bar 43 is arranged between right and left blocking plates 32, 33. When the shooting bar 43 continues to move forward, the tip of a coach shooting trigger link 51 makes contact with the side connecting surface 49 in the proximal end section of the shooting bar 43. Consequently, a shooting trigger 31 which is a second trigger moves the shooting bar 43 to a remote position after perfectly fastening the body tissue, and arrests the rotation of the shooting trigger 31 until the shooting trigger link 51 can be engaged with the terminal engaging surface of the shooting bar 43. Thus, a blocking trigger 30 which is a first trigger and the shooting trigger 31 can be mutually independently rotated.

摘要： PROBLEM TO BE SOLVED: To provide an assembly of a hand piece and a switch allowing a surgeon to freely gain access to tissue and perform an operation for the tissue without caring about the relative position between the switch and a surgical blade. SOLUTION: This hand piece has a main body 150 provided with a distal end 152 and a proximal end 154 for receiving an electric cable 22 and including a first conductive member 170, a switch end cap 200 connected to the main body, and a surgical instrument 30 detachably connected to the main body, wherein the switch end cap has a switch mechanism 110 and a second conductive member 310 engaged with the first conductive member, and while the electric connection between the main body and the switch end cap is kept, the hand piece can be rotated around the main body.

摘要： The present invention provides a surgical handpiece having a switch end cap detachably and rotatably connected to the handpiece body. A surgical instrument is inserted within the handpiece body so that a portion thereof extends beyond the handpiece body and is actuated to perform a surgical operation. The switch end cap includes a switch mechanism having one or more switch button members for selectively signaling the level of power to be delivered to the handpiece from a power source. According to one aspect of the present invention, the switch mechanism within the switch end cap is electrically connected to the handpiece body in such a manner that permits the switch end cap to be freely rotated about the handpiece body, while still maintaining the electrical connection therebetween. This is accomplished by having conductive finger members and complementary conductive members provide the electrical connection between the switch end cap and the handpiece body. This permits a user to position the switch end cap in a desired location relative to the handpiece body and the instrument.

摘要： A linear surgical stapler having clamping and firing triggers pivotally mounted to the frame of the instrument for pivotal rotation toward a hand grip is disclosed. The clamping trigger is positioned between the firing trigger and the hand grip. Each of the triggers are pivotally mounted to pivot pins spaced from each other within the body portion of the frame. Pivotal rotation of the first trigger is independent of pivotal rotation of the second trigger. When the clamping trigger is pivotally rotated toward the hand grip, the clamping and firing transmission assemblies move distally in tandem. Before the first trigger is pivoted, the firing transmission assembly blocks pivotal rotation of the second trigger. When the first trigger is pivoted, the initial distal movement of the firing transmission assembly enables the firing trigger to be in a position to pivotally rotate, and therefore cause the firing of staples. Additionally, a feature enabling the retention of the clamping trigger in intermediate and fully clamped positions is disclosed, where upon release of the retention feature, the clamping trigger can return to its original position by overriding the intermediate position. Finally, although the invention is described with particular reference to a linear stapler containing clamping and firing triggers, it has broader applicability to any surgical instrument which has first and second triggers pivotally actuated to transmit work to an end effector for performing first and second surgical functions during a desired surgical procedure.
