Abstract: A surgical tool adaptor includes a distal interface member and a proximal holder. The surgical tool adaptor is formed with a lumen through the distal interface member and the proximal holder for passing a guiding element (e.g., K-wire) distally through the distal interface member. The proximal holder includes a locking element for locking the guiding element in the lumen and the distal interface member includes a connecting element for connecting to a surgical tool. The proximal holder is movable relative to the distal interface member so that the proximal holder is movable to a position wherein the guiding element does not protrude proximally out of the proximal holder.

Abstract: A surgical tool adaptor (10) includes a distal interface member (12) and a proximal holder (14). The surgical tool adaptor is formed with a lumen (16) through the distal interface member and the proximal holder for passing a guiding element (24), e.g. a K-wire, distally through the distal interface member. The proximal holder includes a locking element (26) for locking the guiding element in the lumen and the distal interface member includes a connecting element (18) for connecting to a surgical tool. The proximal holder is movable relative to the distal interface member so that the proximal holder is movable to a position wherein the guiding element does not protrude proximally out of the proximal holder.

Abstract: An actuating element for actuating an instrument for performing minimally invasive interventions comprises a first handle half-shell and a second handle half-shell movable relative to each other and connected with each other at one end by a biasing mechanism; a tube arranged substantially centrally between the handle half-shells; a linkage mechanism arranged between the handle half-shells and the tube in order to transmit an actuating movement of the handle half-shells; a locking mechanism with a latching rocker arranged on the first handle half-shell and a locking rocker arranged on the second handle half-shell, wherein the two rockers enter into locking connection with each other through an opening provided therefor in the tube when the handle half-shells are moved together, and wherein the rockers are mounted around a pivot axis such that a swiveling or pivoting movement of the rockers lies within a plane defined by the handle half-shells.

Abstract: A torque limiting device includes a handle; a drive shaft attached to the handle; a torque limiting assembly coupled to the drive shaft; the torque limiting assembly further including a shaft element; a first transmission member housing the shaft element; a second transmission member, the second transmission member being fixed to the shaft element and interacting with the first transmission member.

Abstract: A torque limiting device (10; 110; 210), comprising: a handle (12; 112; 212); a drive shaft (14; 114; 214) attached to the handle (12; 112; 212); a torque limiting assembly (20; 120; 220) coupled to the drive shaft (14; 114; 214); the torque limiting assembly (20; 120; 220) further comprising a shaft element (40; 140; 240); a first transmission member (30; 130; 230) housing the shaft element (40; 140; 240); a second transmission member (46; 146; 246), the second transmission member (46; 146; 246) being fixed to the shaft element (40; 140; 240) and interacting with the first transmission member (30; 130; 230).

Abstract: An instrument for use in minimally-invasive procedures generally including a pair of coaxially arranged shafts, an end-effector at the distal ends of the shafts, and an actuator at the proximal ends of the shafts. The end-effector is in the form of a suture holder which includes a first, fixed arm at a distal end of a first, fixed outer shaft, and a second, movable arm at a distal end of a second, movable inner shaft. The fixed arm includes a u-shaped end, which defines an opening adapted to receive a portion of an elongate flexible suture material. A closure pin fixed at an end of the movable arm moves back and forth, opening and closing the opening in the u-shaped end of the fixed arm. The closure pin extends from the movable arm into a pin guide opening through one leg of the u-shaped end of the fixed arm.

Abstract: An instrument for endoscopic minimally invasive procedures has a shaft with a working end, such as a clamp, scissors, forceps, or the like. Handle portions extend in an opposed relationship and pivot relative to the shaft. When the handle portions are moved about respective pivot points, the working end of the surgical instrument is actuated. The first and second handle portions each have an indented grasping segment in which a surgeon's finger or thumb may rest. The grasping segments have rounded cross-sections to facilitate a surgeon rotating the handle with a finger and another finger or thumb. The indented portions form a narrow portion when the handle is in a closed configuration. There may be a 1:1 ratio between handle movement and that of the working end, and the balance point of the instrument may be at the distal end of the handle.

Abstract: A trocar system (10) comprises a trocar tube (11), a trocar plunger (12) and a valve housing (13) formed on the end of the trocar tube (11) facing away from the patient. The trocar tube (11) is produced from a flexible material which is stabilized by a spiral (22). The trocar tube (11) has a taper at the end (21) next to the patient which can be supported at a circular shoulder (15) with the trocar plunger (12) inserted into the trocar tube (11). The trocar tube (11) can be bent in the direction of arrow (23) and stretched in the direction of arrow (24).
