Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a micro-hole guide device for hard bone surface. Background Art

[0002] In orthopedic bone grafting surgery or when using bone cement, in order to make the bone graft material or bone cement fully contact with human bone tissue and improve stability, the contact surface of human bone tissue grafting is required to have a good trabecular microporous structure. However, the bone of the bone graft surface is usually sclerotic bone, which is very hard, and it is difficult for the bone graft material and bone cement to fully contact. Traditional micropore creation on hard bone surface usually uses Kirschner wires to create holes and manual tapping to create micropores on the bone surface. This method is very unstable. If too much force is used, the hole is too large, and if too little force is used, the hole is small, which cannot meet the actual clinical needs. Utility Model Content

[0003] The utility model aims to provide a micro-hole guide device for making a hard bone surface, so as to improve the success rate and efficiency of making micro-holes in artificial bones.

[0004] The purpose of the utility model can be achieved through the following technical solutions.

[0005] A micro-hole guide device for making micro-holes on a hard bone surface comprises a guide tube, an end head and a micro-hole cone for making micro-holes. The end head is fixed to one end of the guide tube, and a plurality of identical micro-hole cones are fixed to the front end surface of the end head.

[0006] The utility model can use different knocking forces to knock the guide tube according to different requirements for making microholes, and control the movement of the microhole cone on the end to make microholes.

[0007] The utility model also has the following preferred designs:

[0008] The front end surface of the end head of the utility model is provided with four circles of micro-hole cones in an annular array from the center inside to the outside.

[0009] Preferably, the number of micropore cones on the front end face of the end piece from inside to outside in each circle is 5, 10, 15 and 20 respectively. The efficiency of making micropores is improved by multiple micropore cones, and the micropore cones can be welded on the end piece.

[0010] The bottom diameter of the microporous cone of the utility model is 2 mm, and the cone height is 2 mm.

[0011] Preferably, the end head and the guide tube are both cylindrical, and the diameter of the end head is greater than the diameter of the guide tube.

[0012] The utility model has the following beneficial effects:

[0013] The utility model can use different knocking forces to knock the guide tube according to different requirements for making microholes. The force applied to the guide tube is transmitted to the end head and the microhole cone. The movement of the microhole cone on the end head is controlled to make microholes. The required microholes can be made by knocking the guide tube with a fixed force, and the multiple microhole cones arranged on the end head can improve the efficiency of making microholes.
