A surgical instrument for applying surgical staples to tissue comprises an end effector with a first and a second jaw that are movable between an open and a closed position. The instrument includes a drive element configured to move distally from the shaft into the end effector to deliver one or more staples to the first and second jaws. The instrument further includes at least one actuating rod extending through the shaft laterally to the drive element relative to the longitudinal axis and configured to move the jaws between the open and closed positions. Positioning the jaw actuator laterally to the drive element creates space for the drive element to deliver multiple staples to the jaws without interfering with the opening and closing of the jaws.

A surgical clamp assembly for clamping tissue and supporting a navigation tracker. The assembly includes a clamp body. Clamp arms are coupled to the clamp body to grip tissue. At least one of the clamp arms includes a distal portion having a clamp surface to grip tissue and a proximal portion that is pivotable relative to the clamp body about a first pivot. A linear displacement mechanism and a carrier are coupled to the clamp body. The carrier is moveable relative to the clamp body along a carrier axis in response to movement of the linear displacement mechanism. The carrier is coupled directly to the proximal portion of the clamp arm. The clamp arm is also pivotable relative to the carrier about a second pivot in response to movement of the carrier.

An orthopaedic surgical instrument assembly operable to taper lock orthopaedic components to one another includes a taper assembly instrument (150) having a handle (182) with a draw rod (154, 156) extending therethrough so as to be slidable relative to the handle and a clamp instrument (60) configured to selectively engage the taper assembly instrument so as to move the draw rod relative to the handle. A sacrificial tensile bar component (180) of the taper assembly instrument is configured to break when a predetermined load has been applied to the orthopaedic components. A method of using an orthopaedic surgical instrument assembly to taper lock orthopaedic components to one another is also disclosed.

Surgical tools (10) are disclosed comprising a surgical clamp (20) having at least two, preferably exactly two, legs (21) and a base (22) connecting the legs (21). The tools (10) comprise one or more of the following additional elements: a handle (30) integrally connected to the clamp (20), wherein the handle (30) is connected to the base (22) of the clamp (20) by at least a predetermined first breaking point (91); a drilling aid (40) having at least two openings (41) the distance (D) between which is greater than the distance (d) between the legs (21) of the clamp (20); a drill bit (50) connected, in particular at a first end (51), to the handle (30) by at least a predetermined third breaking point (93);a parting opening (42) designed such that, in particular after separation of the drilling aid (40) from the handle (30), the clamp can be received in the parting opening (42), particularly in the region of the first predetermined break point (91), such that the clamp (20) can be separated from the handle (30) at the first predetermined break point (91). More generally, one-piece surgical tools (10; 10') having at least two elements interconnected by predetermined break points are also disclosed.

A pelvic bone plate for use in for stabilizing a fracture of a pelvic bone of a patient includes a brim segment configured to be affixed to a portion of a pelvis of a patient and a quadrilateral surface (QLS) segment coupled to the brim segment via at least one bridge. The QLS segment can include a bearing surface configured to be arranged directly adjacent to a QLS of the pelvis and an engagement surface substantially opposing the bearing surface that is configured to be engaged by a surgical clamp. The brim segment can include a plurality of openings configured to receive one or more fasteners.

A surgical clamp for aligning the margins of incised or wounded tissue has jaws with parallel clamping faces, and a handle for manipulating the clamp to align the margins of the tissue. The jaws are in a normally closed position, however they can be opened by compressing the handle to open the jaws. Prongs project from the inferior surface of the jaws. The clamp is positioned in a desired position over the margins of a wound to be closed, the prongs engage the margins of the wound to be aligned, and the jaws are closed by releasing compressive force on the handle. As the jaws close the prongs help move the tissue into alignment. Suture guide slots through the jaws assist in the placement of precisely placed sutures across the incision. The disclosed surgical clamp is particularly suited for selectively closing and reopening surgical incisions, such as a sclerotomy incision in the eye. Methods are disclosed for using the clamp during intraocular and other surgical or minimally invasive procedures. In one example the clamp is used during implantation into the retina of a scaffold on which choroid and retinal pigment epithelium cells and retina grow in a three-dimensional matrix that mimics the native structure of the retina.

Methods and devices for carrying out pulsed field ablation are disclosed. Specifically, the instant disclosure includes surgical clamps configured to clamp tissue and determine the distance between repositionable jaws and tailor pulse field ablation energy to the thickness of the clamped tissue, which is indicative of the spacing between the repositionable jaws. Also disclosed are methods of calibrating pulse field ablation devices and methods of using pulse field ablation devices.

Systems, devices, and methods for electroporation ablation therapy are disclosed, with the device including a first jaw including a plurality of first electrodes and a second jaw including a plurality of second electrodes. The first jaw and the second jaw may be substantially rigid, elongate, and collectively define a longitudinal axis. The first jaw and the second jaw may be configured to engage tissue therebetween during use.

Surgical devices and related methods are disclosed. An example surgical device may include an end effector disposed at a distal end of the shaft, the end effector comprising a head, the head comprising an articulating mechanism, the articulating mechanism being operable to move a first jaw between an open position in which the first jaw and a second jaw are separated and substantially non-parallel and a closed position in which the first jaw and the second jaw are substantially adjacent and substantially parallel, where each of the first jaw and the second jaw comprises a first substantially straight portion proximate the head, a second substantially straight portion, a third substantially straight portion distant from the head, a first curved portion between the first substantially straight portion and the second substantially straight portion, and a second curved portion between the second substantially straight portion and the third substantially straight portion.

The application discloses a composite heat insulation structure suitable for radio frequency sealing and plasma ablation, and relates to the field of electrosurgical instruments. The composite heat insulation structure is arranged in a non-working area of a surgical clamp and is used for limiting heat diffusion and non-target conduction in a multi-energy working condition. The composite heat insulation structure comprises a first functional layer and a second functional layer. The first functional layer is arranged outside a metal base of the surgical clamp and is used for limiting heat and current diffusion to the non-working area in a radio frequency sealing working condition. The second functional layer is arranged outside the first functional layer and is used for improving the electrical insulation stability in a wet environment in a plasma ablation working condition. The composite heat insulation structure is designed in layers and is matched with differentiated functional layers, and is specifically adapted to different working condition requirements of radio frequency sealing and plasma ablation, so that the pain point that a single structure cannot simultaneously consider high-temperature heat insulation and wet-state insulation is effectively solved.
