Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a bone chip collector for dentistry. Background Art

[0002] With the development of science and technology, the improvement of people's living standards and health awareness, more and more patients with missing teeth have accepted dental implants as a restoration method. Dental implants are called the "third set of teeth" of humans and are currently the most ideal restoration method after tooth loss. Due to various reasons, many dental implant patients have insufficient bone mass in the implant area. This insufficient bone mass in the implant area will bring certain risks to the dental implant surgery and reduce the long-term success rate of dental implants, especially in the anterior tooth area, which will also affect the appearance. In clinical practice, there are many solutions and applications of bone repair materials for dental implant patients with insufficient bone mass.

[0003] A primary condition for the success of dental implants is to ensure that there is enough alveolar bone in the implant area. However, during dental implant surgery, insufficient bone around the implant is often encountered, and most of the time, autologous bone or xenogeneic bone is used for repair. Although xenogeneic bone has good biocompatibility and the ability to guide bone formation, it lacks osteoinductivity and needs to be mixed with autologous bone and biomembrane for reliable results, and it is expensive. Autologous bone is considered to be the most ideal transplant material because of its direct bone formation ability, but the acquisition of autologous bone often requires the opening of a second surgical area, and the corresponding surgical equipment needs to be prepared, which prolongs the operation time, increases the patient's pain and the possibility of complications, especially when the bone defect around the implant is small, there is often a sense of loss.

[0004] Therefore, there is an urgent need for a simple and easy-to-use bone chip collector to collect mixtures such as bone crushing chips. Utility Model Content

[0005] The purpose of the present application is to provide a dental bone chip collector which has a simple structure and is easy to operate.

[0006] The embodiments of the present application can be implemented through the following technical solutions:

[0007] A dental bone chip collector comprises a main body, a handle, a nozzle, a limiting structure and a bone scraper. The two ends of the main body are respectively fixedly connected to the handle and the nozzle, and the main body and the nozzle form a collection chamber for bone powder to pass through and store.

[0009] Furthermore, the main body realizes the conversion between the first state and the second state through the connecting shaft. When the main body is in the first state, the first main body and the second main body are closed through the limiting structure to form a collecting chamber; when the main body is in the second state, the second state is that the first main body rotates through the connecting shaft and is staggered with the second body.

[0010] Furthermore, the nozzle comprises a first nozzle and a second nozzle, the first nozzle and the second nozzle are fixedly connected to the first body and the second body respectively, and the first nozzle is an arc structure and smoothly transitions with the first body.

[0011] Furthermore, the bone scraper is a conical structure and is fixedly installed at the end of the second nozzle. The diameter of the bone scraper expands in the direction close to the nozzle. The bone scraper abuts against the first nozzle and the two sides of the bone scraper and the first nozzle form a through hole for bone powder to pass through.

[0012] Furthermore, the limiting structure includes a buckle, which is an inverted L-shaped structure and is arranged at any end in the width direction of the second main body. When the main body is in the first state, the buckle is engaged and connected with the first main body.

[0026] The present application provides a dental bone chip collector. Figure 1 and Figure 2The overall structure diagrams of the dental bone chip collector in the present application in the second state and the first state are shown respectively. Figure 1 and Figure 2 As shown, it includes a main body 1, a handle 3, a nozzle 5, a limiting structure 2 and a bone scraper 6, the two ends of the main body 1 are respectively fixedly connected to the handle 3 and the nozzle 5, and the main body 1 and the nozzle 5 form a collection chamber for bone powder to pass through and store, and the bone scraper 6 is fixedly connected to the end of the nozzle 5.

[0027] Furthermore, the main body 1 includes a first main body 11, a second main body 12 and a connecting shaft 13, the first main body 11 and the second main body 12 are rotatably connected through the connecting shaft, the limiting structure 2 is arranged between the first main body 11 and the second main body 12, and the main body 1 realizes the conversion between the first state and the second state through the connecting shaft 13. When the main body 1 is in the first state, the first main body 11 and the second main body 12 are closed through the limiting structure 2 to form a collecting chamber, and the collecting chamber is used to collect the bone powder scraped by the scraper 6; when the main body 1 is in the second state, the second state is that the first main body 11 rotates through the connecting shaft 13 and is staggered with the second main body 12, so as to facilitate medical staff to take bone powder.

[0028] Furthermore, the nozzle 5 includes a first nozzle 51 and a second nozzle 52, the first nozzle 51 and the second nozzle 52 are fixedly connected to the first body 11 and the second body 12 respectively, the first nozzle 51 is an arc structure and smoothly transitions with the first body 11, and the cross-sectional area of ​​the nozzle 5 along its vertical direction gradually decreases in the direction away from the handle 3. During use, the target position can be reached more accurately to scrape bone powder.

[0029] Furthermore, the bone scraper 6 is a conical structure and is fixedly installed at the end of the second nozzle 52. The diameter of the bone scraper 6 expands in the direction close to the nozzle 5. The bottom edge of the bone scraper 6 is a blade for scraping bone powder. The two sides of the bone scraper 6 and the first nozzle form a through hole for bone powder to pass through. When the bone scraper 6 is in the process of scraping bone powder, due to the conical structure of the bone scraper 6, the scraped bone powder accumulates on the bottom edge of the bone scraper 6 and enters the collecting chamber from the through hole, thereby achieving the acquisition and collection of bone powder.

[0030] In some preferred embodiments of the present application, the bone scraper 6 is made of stainless steel.

[0031] In some preferred embodiments of the present application, the main body 1, the limiting structure 2, the handle 3 and the nozzle 5 are all made of plastic materials, which can save costs and reduce waste of resources.

[0032] Furthermore, the limiting structure 2 includes a buckle 21, which is an inverted L-shaped structure and is arranged at any end of the second body 12 in the width direction. Figure 1 As shown in the figure, D is the width direction. When the main body 1 is in the first state, the buckle 21 is engaged with the first main body 11 to achieve the limitation and fixation of the first main body 11.

[0033] Furthermore, the limiting structure 2 includes a second protrusion 23 provided on the second body 12, such as Figure 3 As shown, when the main body 1 is in the first state, the second protrusion 23 is engaged with the first main body to limit and fix the first main body 11, ensuring that the first main body 11 and the second main body 12 are not separated during operation. At the same time, the first main body 11 is provided with a second groove 231 that is engaged with the second protrusion 23. The connection between the second protrusion 23 and the second groove 231 allows the collection chamber to be divided into a main chamber and a secondary chamber. The main chamber is a chamber close to the nozzle 5, which is used to collect bone powder. Since a small amount of bone powder is required for each operation, the main chamber can meet daily needs. At the same time, the reduction in volume is more conducive to the collection of bone powder.

[0034] Furthermore, the second body 12 is provided with a stopper 121 along its axial direction, the stopper 121 and the buckle 21 are on the same side of the second body 12, the stopper 121 is fixedly connected to the second body 12 and the stopper 121 can abut against the first body 11, and when the body 1 is in the first state, the stopper 121 abuts against the first body 11, so that the first body 11 is fixed, is not easy to loosen during human operation, and is more stable and reliable.

[0035] Further, the limiting structure 2 includes a first protrusion 22, which is arranged at the end of the second main body 12 away from the buckle 21, and the first protrusion 22 is fixedly connected to the first main body 11 and protrudes toward the end away from the stop block 121. At the same time, a first groove 221 corresponding to the position and size of the first protrusion 22 is provided on the second main body 12, and the first groove 221 is used to accommodate the first protrusion 22. When the main body 1 is in the first state, the first protrusion 22 is located in the first groove 221. When the bone powder needs to be taken out according to actual conditions, the first protrusion 22 is pulled to rotate, which can further overcome the resistance brought by the buckle 21 and the second protrusion 23 when limiting the first main body 11, and the operation is more convenient.

[0036] In some preferred embodiments of the present application, the surface of the handle 3 is a threaded anti-slip structure. Since the operating environment of the dental bone chip collector is in the oral cavity, the operable space is small. If improper force is used, it may cause damage to other surrounding tissues. The threaded anti-slip structure can effectively increase the friction between the hand and the dental bone chip collector, so as to better control and apply force to it.

[0037] Further, compared with other bone chip collectors, the dental bone chip collector in the present application has a simple structure and is more convenient to operate. During the operation, there is no need to connect the drive structure. When bone powder needs to be obtained, only manual operation is required, which shortens the operation time and reduces the possibility of patient pain and complications. At the same time, the dental bone chip collector in the present application is not provided with a filter, and the scraping and collection steps of bone powder are simpler and easier to operate. The collected bone powder has good osteogenic activity in histology, and it is already in powder form, and can be directly used for transplantation without reprocessing. In addition, it also contains a small amount of blood clots and bone marrow. Bone tissue contains both cancellous bone and cortical bone, and cancellous bone has strong osteogenic ability and anti-infection ability, rapid revascularization, and good stability of cortical bone, which is conducive to maintaining the shape of the graft. Therefore, collecting bone powder for transplantation has the advantages of both. At the same time, a small amount of blood clots can increase the adhesion of the graft, which is conducive to shaping and retention, and is also conducive to revascularization. Bone marrow tissue has strong osteogenic activity, which further increases the osteogenic ability of the graft. After the bone graft is collected, the mesenchymal cells in the recipient area can differentiate into osteoblasts under the action of growth factors and migrate into the graft to play an osteogenic role. With the growth of blood vessels, bone formation and bone remodeling proceed simultaneously, eventually forming a good bone bond with the implant.

[0038] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications may be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
