[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0027] For further understanding the contents of the utility model, the utility model is described in detail with reference to the drawings.

[0028] With reference to Figures 1-5 The utility model discloses a hollow drill for step type transzonal implantation, including drill rod 1, the right side of drill rod 1 is fixedly connected with connecting rod 2, and this connecting mode guarantees the stability between both, and will not appear loose in the drilling process, ensures the structural stability of the whole hollow drill. The right side of connecting rod 2 is fixedly connected with mounting seat 4, and mounting seat 4 is used to install the hollow drill on corresponding drilling equipment, so that the hollow drill can work under the driving of equipment, and different mounting seat 4 design can be adapted to multiple types of drilling equipment, improve the versatility of the hollow drill.

[0029] Water inlet structure details: the inside of the front end of connecting rod 2 is provided with water inlet 3, which is the inlet of water flow into the hollow drill. The inside of connecting rod 2 is also provided with water inlet tank 7, and water inlet 3 is communicated with water inlet tank 7, after water enters water inlet 3, along water inlet tank 7. The inside of drill rod 1 is provided with connecting groove 9, and water inlet tank 7 is communicated with connecting groove 9, so that water flow can smoothly enter drill rod 1 from connecting rod 2, provides water source for subsequent cooling and chip removal, and can conveniently add medicine.

[0030] The polishing assembly is configured as follows: the polishing assembly comprises a triangular drill 6 arranged on the left side of the connecting rod 2, which is triangular in shape. The right side of the triangular drill 6 is fixedly connected with four-section drill bits 5, and the drill bits 5 increase in size from left to right. This design allows the smaller drill bits 5 to first contact the bone and perform preliminary drilling during the drilling process. As the drilling process proceeds, the larger drill bits 5 play a role in turn, gradually expanding the diameter of the drill hole, thereby ensuring the accuracy and quality of the drilling. The four-section drill bits 5 are each provided with a conveying groove 8 for conveying the cut bone chips and cooling water during the drilling process, so as to prevent the accumulation of bone chips from affecting the drilling effect. The middle end of the drill bit 5 is provided with a water outlet groove 10. The cooling water flowing into the connecting groove 9 can reach the middle end of the drill bit 5 through the conveying groove 8 and then flow out of the water outlet groove 10, thereby directly cooling the drilling site, reducing the temperature during drilling, and reducing the friction loss between the drill bit 5 and the bone.

[0031] Working principle: the triangular drill 6, due to its special triangular shape, can play a good positioning role when it contacts the zygoma, helping the doctor to more accurately control the drilling direction. After the triangular drill 6 is positioned, the drill bit 5 starts to work. The four-section drill bits 5, which increase in size from left to right, first contact the bone with the smallest drill bit 5 on the left side to perform preliminary drilling. As the drilling device advances, the subsequent larger drill bits 5 expand the drill hole in turn, realizing a step-by-step drilling process and ensuring that the drilling accuracy and diameter meet the requirements of implantation. Cooling water is introduced into the water inlet 3. After the cooling water enters the water inlet 3, it flows into the connecting groove 9 along the water inlet groove 7 and then enters the inside of the drill rod 1 through the connecting groove 9. Then, the cooling water reaches the middle end of the drill bit 5 along the conveying groove 8 and finally flows out of the water outlet groove 10, directly acting on the drilling site to cool the drill bit 5 and the drilling area, reduce the high temperature generated during drilling, avoid changes in the performance and hardness of the drill bit 5 due to high temperature, thereby reducing the friction loss between the drill bit 5 and the bone, prolonging the service life of the drill bit 5, and facilitating the introduction of medicine.
