An instrument tray 100 is known. The screw tool tray 100 uses a plurality of screw tools X having different shapes used for fixing the osteosynthesis plate by being fitted in the receiving portions 101 in advance. Then, a medical practitioner such as a doctor or a nurse attaches the screw tool X to be used to the tip of a tightening tool Y such as a driver from among the plurality of screw tools X fitted in the receiving portion 101, Used for plate fixation. Specifically, when the medical practitioner attaches the screw tool X to the tightening tool Y, the tip of the tightening tool Y advances vertically toward the upper surface of the head X1 of the screw tool X, and the screw tool X The tip Y1 of the tightening tool Y is pushed into the groove X3 provided in the head X1. Thereby, the front-end | tip part Y1 of the fastening tool Y bites into the groove part X3, and the screw tool X is mounted | worn with the fastening tool Y with a frictional force.

  However, since the screw tool tray 100 is used by being placed on the work table, the medical practitioner unintentionally advances the tightening tool Y from the oblique direction with respect to the upper surface of the head X1, or the screw. Despite the insufficient mounting of the tool X to the tightening tool Y, it may be assumed that the tip Y1 of the tightening tool Y has been sufficiently pushed into the groove X3, and the mounting work may be terminated. . When the screw tool X is not securely attached to the tightening tool Y, the screw tool X is tightened during the movement from the work table on which the tray 100 is placed to the position for fixing the plate. There is a risk of falling off the tool Y. In particular, if the screw tool used to fix the osteosynthesis plate is dropped on the floor surface or other undisinfected parts even though the unit price is expensive, for reasons of hygiene The inconvenience arises that the screw tool X which has to be disposed of and has fallen off from the tightening tool Y cannot be reused.

On the other hand, as a holder for holding a plurality of screw tools, a holder in which a plurality of funnel-shaped receiving portions are formed along the longitudinal direction of a plate-like body is known (see Patent Document 1). Such a holder holds a plurality of screw tools having the same shape in a receiving portion and supplies them to a robot. When such a holder is used for an operation without using a robot, the tip of the shaft portion X2 of the screw tool X touches the work table when the holder is placed on the work table, which is not preferable in terms of hygiene.
