A method and device provides features for the temporary “parking” of sutures with respect to a cannula. In the preferred embodiments the features are slots that maintain tension on, and orientation of, sutures placed therein. The slots or features may be integral with the cannula or part of a separate device which may be removably affixed to the external portion of a cannula. The invention eliminates the multiple steps inherent in current suture management techniques for arthroscopic procedures, particularly rotator cuff repair and assists in tensioning / advancement of tissue into its repair site.

The invention relates to a special triangle instrument for the teaching field, and specifically relates to a triangle instrument which is provided with an aluminium-chromium alloy step slot corner pointer and is adjustable in the same plane. As the improvement, an upper contour of a rotary disk is provided with an arched convex beam; an upper plane of an edge scale is provided with a step convex trail; a transition convex bar is arranged between the step convex trail and the upper plane of the edge scale, and is centrosymmetric; a step groove is formed in a lower plane of a sliding plate; a transition groove is arranged between the step groove and the lower plane of the sliding plate, and is centrosymmetric; ball base step holes are formed in the lower plane of the sliding plate, and are symmetrically arranged at two sides of the transition groove; the outer protruding sphere of the outer side surface of a sliding ball base on an outer half piece of the sliding ball base on the sliding ball touches the upper plane of the edge scale sliding plate; the step groove on each movable plate is slidingly coordinated with the step convex trail on the adjacent movable plate; and specifically on the upper plane corner scales of the edge scale are corresponding to a corner pointer on the back of the lower plane of the sliding plate on the location so that the rotation angle between the rotary disk part and the scale plate part can be controlled conveniently and visually.

A stabilizing assembly includes a retaining device settled between a drawable carrier and a cabinet body for preventing the drawable carrier from swinging in sliding. The retaining device includes two rails fixed to two opposite laterals of the drawable carrier. Each of the rails has a rack. Two gears engaging with the racks are connected by a rod and rotate simultaneously. Two bushes at two ends of the rod are received in supporting seats that are fixed on the cabinet body or the drawable carrier and allowed to shift vertically. Two stop portions, as a stop unit, each extending from the rail toward a side of the rod opposite to another side of the rod facing the rack on the rail are closely adjacent to the retained portions so that the bushes are retained and stopped by the stop unit, and disengagement between the racks and the gears is prevented.
