[0020] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0021] Figures 1 to 5 , is a preferred embodiment of an adjustable bone drilling locator provided by the utility model. Figures 1 to 5As shown, the adjustable bone drilling locator includes a drilling positioning guide 10 and a bone surface positioning guide column 20 arranged on the drilling positioning guide 10, the bone surface positioning guide column 20 is matched with a bone surface positioning cone 30, and the bone surface positioning guide column 20 is provided with a plurality of through holes 21 that match the bone surface positioning cone 30. The drilling positioning guide 10 is provided with at least one drill hole 14, and the central axis of the drill hole 14 and the central axis of each through hole 21 converge at the same point. The drilling positioning guide is also connected to a handle 40, so that medical staff can hold the handle 40 with one hand and insert the bone surface positioning cone 30 into the through hole 21 with the other hand for positioning, and then insert the drill rod into the drill hole 14 for drilling. It has a simple structure and is easy to operate. It can prevent displacement during the drilling process, and solves the problem that the hole position may be deviated when drilling holes on the bone in existing bone reconstruction surgery or ligament reconstruction surgery.

[0022] As a first implementation method, Figure 1 As shown, the bone surface positioning guide column 20 is fixedly set on the drilling positioning guide plate 10, and the drill holes 14 are distributed on the side of the drilling positioning guide plate 11. The central axis of each drill hole 14 and the central axis of each through hole 21 converge at the same point, ensuring that the drilling position is accurate and drilling can be performed in different directions.

[0023] As a second implementation method, Figure 2 and Figure 3 As shown, the bone surface positioning guide post 20 is movably arranged on the drilling positioning guide plate 10, and the drill holes 14 are distributed on the side of the drilling positioning guide plate 10. The drilling positioning guide plate 10 is provided with a slot 11 for inserting the bone surface positioning guide post; the drilling positioning guide plate is also provided with a positioning seat 15, which is on one side of the slot 11. The positioning seat 15 is provided with an outer positioning hole 12 for positioning the bone surface positioning guide post in the slot, and an inner positioning hole 22 corresponding to the outer positioning hole 12 is distributed on the side wall of the bone surface positioning guide post, and the outer positioning hole 12 and the inner positioning hole 22 are matched with a positioning pin 13; like this, medical staff can adjust the position of the bone surface positioning guide post 20 in the slot 11 as needed, and use the positioning pin 13, the outer positioning hole 12 and the inner positioning hole 22 to position the bone surface positioning guide post 20, while the central axis of each drill hole 14 and the central axis of each through hole 21 converge at the same point to perform drilling operation to ensure that the drilling position is accurate.

[0024] In the second embodiment, the length of the slot 11 is consistent with the width of the bone surface positioning guide column 20, and the width of the slot 11 is consistent with the thickness of the bone surface positioning guide column 20, so that it is convenient for the bone surface positioning guide column 20 to slide up and down, and at the same time, it also limits the bone surface positioning guide column 20 to prevent the bone surface positioning guide column 20 from shifting laterally.

[0025] The bone surface positioning guide post 20 is arc-shaped, and multiple through holes 21 are distributed in an arc shape on the bone surface positioning guide post 20. The central axis of each through hole 20 is consistent with the radial line of the bone surface positioning guide post 20, avoiding displacement when adjusting the bone surface positioning cone 30, thereby alleviating the patient's pain. Figure 1 and Figure 2 As shown, the bone surface positioning guide column 20 is provided with five through holes 21, and the drilling positioning guide plate 10 is provided with three drill holes 14, wherein the through hole 21 at the middle position corresponds to the drill hole 14 at the middle position.

[0026] like Figure 5 As shown, the bone surface positioning cone 30 includes a cone 31 and a handheld end 32 provided at one end of the cone, and a conical puncture portion 311 is formed at the other end of the cone for easy positioning. The diameter of the handheld end 32 is larger than the diameter of the through hole 21, preventing the bone surface positioning cone 30 from passing through the through hole 21 and avoiding medical accidents. Among the inner walls of the through hole 21, the inner wall on the left side and the inner wall on the right side are planes, and the inner wall on the upper side and the inner wall on the lower side are arc surfaces; the cross section of the cone is consistent with the cross section of the through hole, and the cross section of the entire through hole 31 is similar to a lantern shape; the cross section of the cone is consistent with the cross section of the through hole, so that when the cone 31 is inserted into the through hole 21, the rotation of the cone can be limited.

[0027] The drilling positioning guide plate 20 is connected to the handle 40 as a whole through a connecting plate 50. The width of the connecting plate 50 is smaller than that of the positioning guide plate 20, which is convenient for connection with the handle 40 and reduces the weight, making it easier for medical staff to operate.

[0028] The specific method of using the adjustable bone drilling locator is as follows: 1) the medical staff can hold the handle 40 with one hand and select a suitable through hole 21 with the other hand, select a suitable through hole 21, and insert the bone surface positioning cone 30 into the through hole 21; (2) then insert the drill rod into the suitable drill hole 14 to drill.

[0029] In summary, the technical solution of the present utility model can fully and effectively achieve the above-mentioned purpose of the utility model, and the structure and functional principles of the present utility model have been fully verified in the embodiments and can achieve the expected efficacy and purpose. Without departing from the principle and essence of the present utility model, various changes or modifications can be made to the embodiments of the utility model. Therefore, the present utility model includes all replacement contents within the scope of the patent application, and any equivalent changes made within the scope of the patent application of the present utility model are within the scope of the patent application of this case.
