Abstract
Description
Technical Field
[0001] This utility model belongs to the field of oral implant technology, specifically relating to a bone harvesting drill for oral implant surgery. Background Technology
[0002] Dental implants, also known as artificial dental implants, do not involve planting natural teeth. Instead, pure titanium metal, which is highly compatible with human bone, is precisely designed and processed into a cylinder or other shape similar to a tooth root. This is then surgically implanted into the alveolar bone in the area of the missing tooth. After a period of healing, a crown is then made on the artificial tooth root.
[0003] Existing bone harvesting drills for dental implant surgery have some shortcomings. Most of them lack assembly capabilities, and when the bone harvesting tooth is damaged, the entire bone harvesting drill needs to be replaced, which increases the cost of use. Therefore, we propose a new bone harvesting drill for dental implant surgery. Utility Model Content
[0004] The purpose of this invention is to provide a bone harvesting drill for oral implant surgery, in order to solve the problem that most of the aforementioned background technologies do not have assembly capabilities.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bone harvesting drill for oral implant surgery, comprising a bone harvesting drill body and a connecting rod, wherein the connecting rod is provided at one end of the bone harvesting drill body, and an insertion block is provided at one end of the bone harvesting drill body, the insertion block and the bone harvesting drill body are fixedly connected, a storage groove is embedded at the top of the insertion block, a first spring is provided inside the storage groove, the first spring and the storage groove are fixedly connected, a buckle is provided inside the storage groove, the buckle and the storage groove are slidably connected, a slot is embedded at one end of the connecting rod, a slot is provided on one side of the slot, and the buckle and the slot are fixed by engaging.
[0006] Preferably, a guide block is provided on one side of the insert, and a guide groove is embedded in the inner wall of the slot, wherein the guide block and the guide groove are slidably connected.
[0007] Preferably, the slot has a top plate inside, the top plate and the slot are slidably connected, and a second spring is provided on one side of the top plate.
[0008] Preferably, the surface of the bone-harvesting drill body is provided with bone-harvesting holes, and there are multiple bone-harvesting holes.
[0009] Preferably, one end of the bone-harvesting drill body is provided with bone-harvesting teeth, and one end of the connecting rod is provided with a connecting part.
[0010] Preferably, there are two sets of guide blocks and guide grooves, located at both ends of the insert block.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The device is assembled by means of a plug, a storage slot, a first spring, a buckle, a slot, and a groove. It can be fixed by simply inserting the plug into the slot and snapping the buckle into the groove, which reduces the cost of using the device.
[0013] 2. The stability of the insert is improved by the provided guide block and guide groove. When the insert is inserted into the slot, the guide block will insert into the guide groove, thereby increasing the contact area between the two and making it less prone to shaking during use, thus improving the usability of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 This utility model provides a technical solution: a bone harvesting drill for oral implant surgery, including a bone harvesting drill body 1 and a connecting rod 2. One end of the bone harvesting drill body 1 is provided with the connecting rod 2, and one end of the bone harvesting drill body 1 is provided with an insert block 3. The insert block 3 and the bone harvesting drill body 1 are fixedly connected. The top of the insert block 3 is provided with a storage groove 4. The inside of the storage groove 4 is provided with a first spring 5. The first spring 5 and the storage groove 4 are fixedly connected. The inside of the storage groove 4 is provided with a buckle 6. The buckle 6 and the storage groove 4 are slidably connected. One end of the connecting rod 2 is provided with a slot 7. One side of the slot 7 is provided with a groove 8. The buckle 6 and the groove 8 are fixed by engaging.
[0020] In this embodiment, when assembling the bone retrieval drill, the insert 3 is inserted into the slot 7. The buckle 6 is squeezed by the inner wall of the slot 7 and retracts into the storage groove 4. At the same time, the first spring 5 is compressed. When the buckle 6 moves to the position of the slot 8, the buckle 6 will be locked into the slot 8 under the reaction force of the first spring 5, thus completing the fixation. When the bone retrieval tooth 14 is damaged, simply press the buckle 6 to pull the insert 3 out of the slot 7, complete the disassembly, and then replace it. There is no need to replace the entire bone retrieval drill, which reduces the cost of use.
[0021] Specifically, a guide block 9 is provided on one side of the insert block 3, a guide groove 10 is embedded in the inner wall of the slot 7, the guide block 9 and the guide groove 10 are slidably connected, a top plate 11 is provided inside the slot 7, the top plate 11 and the slot 7 are slidably connected, a second spring 12 is provided on one side of the top plate 11, a bone extraction hole 13 is embedded on the surface of the bone extraction drill body 1, there are multiple bone extraction holes 13, a bone extraction tooth 14 is provided at one end of the bone extraction drill body 1, a connecting part 15 is provided at one end of the connecting rod 2, and two sets of guide blocks 9 and guide grooves 10 are provided, located at both ends of the insert block 3 respectively.
[0022] In this embodiment, the stability of the insert 3 is improved by the provided guide block 9 and guide groove 10. When the insert 3 is inserted into the slot 7, the guide block 9 will be inserted into the guide groove 10, thereby increasing the contact area between the two and making it less prone to shaking during use, thus improving the usability of the device. The provided top plate 11 and second spring 12 facilitate the disassembly of the device. When the insert 3 is inserted into the slot 7, it will squeeze the top plate 11, thereby compressing the second spring 12. During disassembly, pressing the buckle 6 will cause the top plate 11 to push the insert 3 out of the slot 7 under the reaction force of the second spring 12, thus completing the disassembly.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
