发明名称 Medical cutting instrument for severing muscles and tendons
摘要 A medical cutting instrument for cutting muscles and tendons, with an instrument body that includes a handle on its proximal end and at least one cutting knife in the area of its distal end. To provide a medical cutting instrument that guarantees ease of handling and simple structure along with secure cutting of the muscle/tendon tissue, the instrument body should be of grooved configuration in the area of its cutting knife in such a way that the instrument body includes a hollow space extending in the longitudinal direction of the instrument body to receive and guide the muscle/tendon tissue that is to be cut, such that the instrument body includes an opening extending in the longitudinal direction of the instrument body and the cutting knife constitutes a side of the instrument body.

主权项 1. A medical cutting instrument for cutting muscles and tendons, with an instrument body that comprises a handle on its proximal end and at least one cutting knife in the area of its distal end, wherein the instrument body has a grooved configuration in the area of the cutting knife in such a way that the instrument body comprises a hollow space extending in the longitudinal direction of the instrument body to receive and guide the muscle or tendon tissue that is to be cut, such that the instrument body is configured as an L-shaped rectangular profile with a first side of the L-shape profile extending about the total length of the instrument body and defining the handle at its proximal end and with a second short side-wall of the L-shaped profile extending in the area of the cutting knife rectangular to the first side in the longitudinal direction of the instrument body, wherein the instrument body comprises an opening extending in the longitudinal direction of the instrument body and the cutting knife constitutes one side of the grooved configuration of the instrument body, wherein the cutting knife extends rectangular from the second short side-wall of the instrument body and parallel to the first side of the instrument body which extends about the total length of the instrument body, wherein the cutting knife overlaps a side of the grooved configuration of the instrument body opposite to the cutting knife in a direction perpendicular to the longitudinal axis of the instrument and wherein the cutting knife on the distal end comprises a cutting edge aligned perpendicularly to the longitudinal direction of the instrument body and the proximal side of the cutting knife that is opposite to the cutting edge is configured as running diagonally toward the open side of the grooved configuration of the instrument body, and wherein the hollow space is surrounded and circumscribed by wails on three sides, namely by the first side of the L-shaped profile, the second short side-wall of the L-shaped profile, and the knife.
