Abstract
A medical instrument for placement of a knot, in particular, for operating within closed spaces. With the use of such instrument, the thread can be held, guided and/or manipulated at least on one side of the knot and adjacent thereto by an instrument head in such a way that the knot can be pushed into the vicinity of a target point and placed exactly in the target point by spreading at least one free end of the thread.
Claims20
A medical instrument for directed placement of a knot formed by two free ends of a surgical thread or the like suture material accompanied by formation of a continuous loop, comprising:
- an instrument head for holding, guiding and/or manipulating the surgical thread at least on one side of the knot and adjacent thereto in such a way that the knot can be pushed into the vicinity of a target point and placed exactly in the target point by spreading at least one free end of the thread, said instrument head having a profile for separately holding, guiding and/or handling at least one of the free ends of the thread and the knot and the adjacent portions of the loop and wherein the profile has at least one peripheral region for the free ends and a central region for the knot and their adjacent loop portions and wherein the peripheral and central regions are connected via a recess, said peripheral region having a bevel, for supporting the knot and the free ends, which extends from the outer circumference of the instrument head in the direction of a front part of the instrument head and toward the center line of the instrument head, said bevel ending in the recess.
The medical instrument for directed placement of a knot formed by two free ends of a surgical thread or the like suture material accompanied by formation of a continuous loop, comprising:
- an instrument head for holding, guiding and/or manipulating the surgical thread at least on one side of the knot and adjacent thereto in such a way that the knot can be pushed into the vicinity of a target point and placed exactly in the target point by spreading at least one free end of the thread, said instrument head having a profile for separately holding, guiding and/or handling at least one of the free ends of the thread and the knot and the adjacent portions of the loop wherein the instrument head has a profile with a peripheral region and central region, which regions end in a recess having branches said peripheral region having a bevel, for supporting the knot and the free ends, which extends from the outer circumference of the instrument head in the direction of the front part and toward the center line of the instrument head and ends in the recess approximately at the point where the branches merge;
- wherein one branch of the recess for receiving the free ends is a dead-end branch which extends in the longitudinal direction of the instrument head roughly along the center line of the latter as far as a front part of the instrument head and wherein another branch of the recess for receiving and guiding at least the knot extends from the end of said dead-end branch on the front part side away from the front part at an acute angle and exits from the instrument head.
The medical instrument for directed placement of a knot formed by two free ends of a surgical thread or the like suture material accompanied by formation of a continuous loop, comprising:
- an instrument head for holding, guiding and/or manipulating the surgical thread at least on one side of the knot and adjacent thereto in such a way that the knot can be pushed into the vicinity of a target point and placed exactly in the target point by spreading at least one free end of the thread, said instrument head having a profile for separately holding, guiding and/or handling at least one of the free ends of the thread and the knot and the adjacent portions of the loop and wherein the profile has at least one peripheral region for the free ends and a central region for the knot and their adjacent loop portions and wherein the peripheral and central regions are connected via a recess;
- wherein a dead-end branch of the recess for receiving the free ends extends in the longitudinal direction of the instrument head roughly along the center line of the latter as far as a front part of the instrument head and wherein another branch of the recess for receiving and guiding at least the knot extends from the end of said dead-end branch on the front part side away from the front part at an acute angle and exits from the instrument head, and wherein the central region has a bore hole coaxial to said instrument head for receiving at least the knot in a front part of the instrument head, which bore hole opens into the recess and wherein the diameter of the bore hole is greater than the clear width of the dead-end branch and the bore hole completely penetrates the branch in the axial direction of the instrument head in such a way that a lateral guide for the knot is formed along the bore hole.
