A forceps device includes a grasping part, a support that holds the grasping part, a first rotating shaft that turnably supports the support, a base member that holds the first rotating shaft, guide pulleys arranged coaxially with the first rotating shaft, grasping portion wires, a support pulley, and a support wire. The grasping portion wires run over the guide pulleys and the grasping part without other pulleys therebetween, and transmit a first driving force to the grasping part to move the grasping part. The support pulley is provided on the support, and the support wire runs over the support pulley and transmits a second driving force to the support to turn the support about the first rotating shaft.

The invention relates to a medical instrument having an elongated shaft, a movable tool at a distal end of the shaft, a handle with a movable grip part at a proximal end of the shaft, and a force transmission element which can be moved in the longitudinal direction of the instrument and is operatively connected to the movable grip part and to the tool such that an actuation of the movable grip part is converted into a movement of the tool. The instrument has a spring assembly that is arranged on the handle and has at least one leg spring, which has at least one winding and two legs, and a pin, wherein the at least one winding extends about the pin. When the movable grip part is actuated, a force is applied to at least one of the legs of the leg spring, said force reducing the friction between the winding and the pin such that the leg spring can be rotated about the pin and the force transmission element and the tool can be moved. When a force is transmitted from the tool to the force transmission element in the longitudinal direction thereof, the leg spring cannot be rotated about the pin such that the force transmission element and the tool cannot be moved.

A surgical system includes a detector, comprising an array of pixels configured to detect light reflected by a surgical instrument and generate a first signal comprising a first dataset representative of a visible image of the surgical instrument. The surgical system also includes a processor configured to receive the first signal, generate a modified image of the surgical instrument that includes a control panel. The control panel includes one or more control elements representative of one or more operating parameters of the surgical instrument. The processor is further configured to receive an input to the control panel from a user, the input being effective to change one of the operating parameters. The processor is also configured to generate a command signal based on the input to change the one of the operating parameters.

A left atrium appendage (LAA) isolator, including: a body sized and shaped to fit an at least partially inverted LAA of a human adult, wherein a distal end of said body defines a two-state sealing adaptor interface configured in a first state to apply a radially outward force against a wall of said LAA or against a wall of said LAA opening sufficient to anchor said body to the LAA wall, and in a second state the sealing adaptor interface is configured to apply a radially inward force on a portion of the inverted LAA positioned within said body.

An ultrasonic surgical instrument includes a body, an ultrasonic supported by the body, a shaft extending distally from the body and defining a shaft axis, a waveguide extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade coupled to a distal end of the waveguide and having a primary blade treatment surface configured to treat tissue, and a clamp arm coupled to the distal end of the shaft. The shaft and the waveguide are selectively rotatable relative to one another about the shaft axis through a predefined range of angular motion between an assembly state and an operational state. In the assembly state, the clamp arm and the primary blade treatment surface are rotationally offset from one another. In the operational state, the clamp arm and the primary blade treatment surface are rotationally aligned.

A sensing device for sensing one or more tissue properties includes an adapter assembly, an actuation assembly, a shuttle, and a piston assembly. The adapter assembly is configured to couple to surgical handheld devices. The actuation assembly extends distally from the adapter assembly and is configured to operably couple to and be engaged by handheld devices coupled thereto. The actuation assembly includes a first drive shaft and a second drive shaft. The shuttle has a clamp and a shuttle sensor, and is coupled to the first drive shaft via a coupling. The shuttle sensor is disposed on the clamp. The piston assembly is coupled to the second drive shaft and configured to compress target tissue between the piston assembly and the clamp of the shuttle.

A surgical instrument includes a power pack, an outer shell housing configured to selectively encase the power pack, and an adapter assembly configured to selectively couple the outer shell housing to a loading unit. The outer shell housing includes a motor and a drive shaft coupled to and rotatable by the motor. The outer shell housing includes a drive member supported in a distal portion thereof. The drive member is configured to selectively couple to the drive shaft. The adapter assembly has a drive member supported in its proximal end. The drive member of the adapter assembly is configured to selectively couple to the drive member of the outer shell housing such that rotation of the drive shaft actuates movement of the drive member of the adapter assembly via the drive member of the outer shell housing.

In a method of forming a FinFET, a first sacrificial layer is formed over a source/drain structure of a FinFET structure and an isolation insulating layer. The first sacrificial layer is recessed so that a remaining layer of the first sacrificial layer is formed on the isolation insulating layer and an upper portion of the source/drain structure is exposed. A second sacrificial layer is formed on the remaining layer and the exposed source/drain structure. The second sacrificial layer and the remaining layer are patterned, thereby forming an opening. A dielectric layer is formed in the opening. After the dielectric layer is formed, the patterned first and second sacrificial layers are removed to form a contact opening over the source/drain structure. A conductive layer is formed in the contact opening.
