6 results about "Surgical Clamps" patented technology

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.

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.
