The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.

A surgical clamp jaw is disclosed, having an inner profile and a deflection control profile opposite the inner profile. In one embodiment, the inner profile has a first substantially concave profile in an unclamped position and a second substantially flat profile in a clamped position. In one embodiment, the deflection control profile has one or more sets of corresponding abutment surfaces, at least one set of which is not contacting each other when the inner profile is in the unclamped position and which is contacting each other when the inner profile is in the clamped position. In one embodiment, the surgical clamp jaw defines one or more flexion assistance voids, wherein at least one of the one or more flexion assistance voids is in contact with a gap between one of the one or more sets of corresponding abutment surfaces.

Forceps with improved actuation include a housing and a body that is longitudinally slidable relative to the housing. The body having a peripheral flange extending outward towards the housing. A trigger includes an actuation surface configured to receive a force input from a user. The trigger further including at least one arm configured to transfer the received force input to the body. To inhibit lateral splaying of the at least one arm when the trigger is actuated, the housing includes a first control surface, such as a rib proximate the arm.

Surgical forceps can include a drive pin an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can define a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a pair of flanges located at a proximal portion of the first jaw, where each flange can include a track receiving the drive pin. The inner tube can be located within the outer tube and can extend along the longitudinal axis. The inner tube can include a pair of arms extending from a distal portion of the inner tube. The drive pin can be securable to the pair of arms. The inner tube can be translatable within the outer tube to drive the drive pin along the tracks to move the second jaw between open and closed positions.

An ultrasonic surgical instrument and method of assembly with a predetermined alignment includes first and second modular assemblies and an electrical lockout. The first modular assembly includes at least a portion of an end effector configured to manipulate a tissue. The second modular assembly includes a transducer power circuit and an activation switch electrically connected to the transducer power circuit. The electrical lockout is electrically connected to the transducer power circuit and configured to inhibit the activation switch from powering the ultrasonic transducer with the first and second modular assemblies misaligned from the predetermined alignment such that the first and second modular assemblies are in a locked-out state. The electrical lockout is further configured to allow the activation switch to power the ultrasonic transducer with the first and second modular assemblies in the predetermined alignment such that the first and second modular assemblies are in an operational state.

The present invention relates to a surgical device that is defined as a single-impulse suturing device, which allows both suturing and grasping a needle at the opposite end for one time without any need for another tool to retrieve the needle after being passed through a tissue during the suturing process, and it comprises the following characteristics of; allowing a safe and minimal invasive access to narrow and deep surfaces, performing a well-directed suturing from a determined point due to its semi-mobile jaw structure, having a stopper that enables suturing by staying at a distance from neurovascular structures in an invisible area, and allowing a multiple suturing with the same needle. The invention keeps suturing function of the single-impulse devices reserved and develops the same in addition to combining this function with ergonomic size characteristics and practical handle advantages of double-impulse devices.

An end effector assembly for a forceps includes first and second jaw members, each including a proximal flange extending therefrom. Each proximal flange defines an aperture extending therethrough configured to receive a pivot assembly including first and second pivot pins. The second proximal flange includes a U-shaped cross section having first and second legs defining a slot therebetween. A guard is disposed between the proximal flanges of the first and second jaw members and includes a U-shaped cross section with first and second legs configured to receive the proximal flange of the first jaw member and seat within the slot of the second jaw member. The guard is configured to eliminate gaps between the proximal flanges of the first and second jaw members during angular rotation of the first and second jaw members between a first, spaced apart position to a second, closer position.

A surgical instrument (1) comprises at least three individual components (2,3,4,5,6) arranged movably relative to one another. Each of the individual components (2,3,4,5,6) is directly and movably connected to at least one further one of the individual components (2,3,4,5,6). All of the constituent parts of the surgical instrument (1) are made of a metallic or metal-containing material. Each individual component (2,3,4,5,6) has at least one friction surface region (9,10) which forms a pair of friction surfaces with at least one friction surface region (9,10) of another individual component (2,3,4,5,6). At least one of the two friction surface regions (9,10) of each pair of friction surfaces has a hard-material surface layer (16).
