Abstract: A measuring adapter for a measuring instrument for use in connection with hip prosthesis surgery comprises a measuring head and a connector. The measuring head comprises a front end, a rear end and convex upper surface and is divided into at least two separate sections. The measuring head comprises an axially extending central through-going bore adapted to receive an actuating rod . The measuring head is expandable from a relaxed state to an expanded state by axially displacing the actuating rod in the central through-going bore. The connector is hollow and divided at one end in axial direction of the measuring head into a number of legs corresponding to the number of separate sections of the measuring head; each leg being connected to one of the sections of the measuring head. At least a part of the upper surface of the measuring head is adapted, when in the expanded state, to adopt the shape of a spherical cap or a convex shape comprising at least a spherical segment.

Abstract: A measuring adapter (1) for a measuring instrument for use in connection with hip prosthesis surgery is provided. The measuring adapter (1) comprises a measuring head (2) and a connector (3); the measuring head (2) comprises a front end (2a), a rear end (2b) and an upper surface (4a). The upper surface (4a) is convex. The measuring head (2), along an axial direction of the measuring adapter (1), further comprises a central through-going bore (5) adapted to receive an actuating rod (8). The measuring head (2) is adapted to expand from a relaxed state to an expanded state when the actuating rod (8) is axially displaced in the central through-going bore (5); and the measuring head (2) is divided into at least two separate sections (6). The connector (3) is hollow and slotted at one end in axial direction of the measuring head (2) into a number of legs (7), the number of legs (7) corresponding to the number of the at least two separate sections (6) of the measuring head (2).

Abstract: A post-surgery method for evaluating the quality of an insertion of an orthopedic implant (20) after surgery is provided. The method comprises the steps of determining at least two individual quality parameters (60) derived from at least one radiologic image (40) of the area comprising the orthopedic implant (20). The method further comprises the step of computing a total score (70) based on said at least two individual quality parameters (60), wherein the total score is indicative of the quality of the insertion of the orthopedic implant, and storing the total score.

Abstract: A device for transferring liquid, e.g. local anesthetics, from a reservoir (1) to a hypodermic needle (18) for introduction into tissue. The device comprises a pump chamber (11) in a pump housing (19), which is provided with a manually displaceable pump piston (12), which is pivotably connected to a pump grip (13). The pump housing (19) is fluidly connected to the reservoir (1) through a piercing cannula (3) at an inlet (9), and fluidly connected to the needle (18) at an outlet (20).

Abstract: The invention concerns a measuring instrument, preferably for use in connection with press fit hip prosthesis surgery, whereby it is possible to measure/register size (diameter) and modulus of elasticity of acetabulum and femur for inserting an uncemented socket or uncemented femur component.
