DETAILED DESCRIPTION

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] As attached Figure 1-2A clavicle coracoid bone channel locator shown in the figure includes a fixing frame 1, a slide groove 13 is opened on the upper surface of one end of the fixing frame 1, a slider 14 is embedded and installed on the inner surface of the slide groove 13 of the fixing frame 1, a first adjusting nut 3 is inserted and installed in the middle of the upper surface of the slider 14, a "T"-shaped limiting ring is provided on the lower surface of the first adjusting nut 3, and the first adjusting nut 3 is embedded in the slider 14 through the limiting ring and is clamped and connected to the slider 14.

[0020] A positioning sleeve 2 is inserted and installed on the inner surface of the first adjusting nut 3, and the lower end of the positioning sleeve 2 passes through the fixing frame 1 and extends to the outside. A guide pin 4 is inserted on the inner surface of the positioning sleeve 2. An adjusting screw 15 is installed on the middle part of one side of the outer surface of the slider 14 through a bearing, and the other end of the adjusting screw 15 passes through the fixing frame 1 and extends to the outside. A scale line is provided on the upper part of one side of the outer surface of the fixing frame 1, and a movable opening with a diameter equal to that of the positioning sleeve 2 is opened in the middle part of the lower surface of the fixing frame 1, and a thread is provided on the upper part of the outer surface of the positioning sleeve 2.

[0021] A second adjusting nut 5 is installed at the other end of the fixing frame 1, and a "T"-shaped limiting ring is provided on the upper surface of the second adjusting nut 5. The second adjusting nut 5 is embedded into the fixing frame 1 through the limiting ring and is connected to the fixing frame 1 by clamping. A receiving groove 6 is opened inside the fixing frame 1, and a movable screw 10 is inserted and installed on the fixing frame 1 through the inner surface of the receiving groove 6.

[0022] A limiting sleeve 11 is installed at the lower end of the movable screw 10, and a third adjusting nut 12 is installed on one side of the outer surface of the limiting sleeve 11, and a positioning bracket 7 is inserted and installed on the other side of the outer surface of the limiting sleeve 11. The outer surface of the end of the positioning bracket 7 close to the limiting sleeve 11 is provided with a thread, and a groove 8 is opened on the upper surface of one end of the positioning bracket 7. The notch size of the groove 8 is equal to the diameter size of the guide needle 4, and a "human" shaped supporting foot 9 is provided at the end of the positioning bracket 7 close to the groove 8. The thread diameter sizes of the positioning sleeve 2, the positioning bracket 7, the movable screw 10 and the adjusting screw 15 are all set to be equal.

[0023] During operation, first touch the position of the coracoid process and the clavicle before the operation. After determining the position of the coracoid process and the clavicle, the body surface can be marked and an opening can be made. At this time, the fixing frame 1 can be moved to the position directly above the clavicle, and the slider 14 can be controlled to slide in the slide groove 13 with the cooperation of the fixing frame 1 by turning the adjusting screw 15 counterclockwise, thereby controlling the positioning sleeve 2 to adjust the alignment position. After the alignment position adjustment of the positioning sleeve 2 is completed, the first adjusting nut 3 can be turned clockwise to control the positioning sleeve 2 to extend toward the clavicle alignment positioning position.

[0024] When the positioning sleeve 2 is aligned and in contact with the positioning position, the second adjusting nut 5 can be turned clockwise to control the movable screw 10 to move and extend inside the receiving groove 6. At this time, the limiting sleeve 11 arranged at the lower end of the movable screw 10 can drive the positioning bracket 7 to adjust the alignment position of the coracoid bone as the movable screw 10 extends. When the alignment position adjustment is completed, the third adjusting nut 12 can be turned clockwise to control the positioning bracket 7 to extend toward the alignment position of the coracoid bone. When the supporting foot 9 at the end of the positioning bracket 7 is clamped on the coracoid bone, the guide needle 4 can be inserted into the positioning sleeve 2 and extended toward the position of the clavicle. When the end of the guide needle 4 passes through the clavicle and is embedded in the groove 8 opened on the positioning bracket 7, the channel positioning of the clavicle can be completed.

[0025] In summary: the locator can complete the channel positioning on the clavicle corresponding to the position of the coracoid bone, which is conducive to the smooth progress of treatment.
