Description

Technical Field

[0001] This utility model relates to the field of dental technology, and more specifically, to an automatic rinsing dental implant drill. Background Technology

[0002] In dental implant surgery, implant handpieces are often used in conjunction with dental drills for drilling operations. For example, an implant handpiece proposed in application number "CN202120996215.9" includes an implant handpiece body, which includes a handle, a head, and a drill bit. One end of the head is connected to the handle, and the drill bit is connected to the other end of the head. The axis of the head and the axis of the handle are at an angle in a direction perpendicular to the axis of the drill bit.

[0003] However, in the above-mentioned technical solutions, during the drilling operation, the high-speed rotation of the drill bit generates a lot of heat due to friction with the gingival tissue, and also produces bone fragments and tissue debris. It is necessary to rinse and cool down in time and clean up the debris. Therefore, during the processing, it is often necessary to arrange an additional medical staff to hold a water hose to rinse the drilling area. This not only increases labor costs, but also the stability of the handheld water hose is poor, and the water flow is difficult to accurately and continuously act on the contact area between the drill bit and the gingiva, which can easily lead to untimely rinsing or insufficient rinsing area. Therefore, we propose an automatic rinsing dental implant drill to solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide an automatic rinsing dental implant drill, which solves the problem that during drilling, the high-speed rotation of the drill bit generates a lot of heat due to friction with the gingival tissue, and produces bone fragments and tissue debris. It is necessary to rinse and cool down the drill bit and clean up the debris in time. Therefore, during the processing, it is often necessary to arrange an additional medical staff member to hold a water hose and rinse the drilled area. This not only increases labor costs, but also makes it difficult to accurately and continuously apply water flow to the contact area between the drill bit and the gingiva due to the poor stability of the handheld water hose. This can easily lead to problems such as untimely rinsing or insufficient rinsing area.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic rinsing dental implant drill includes an implant handpiece. A motor is installed at one end of the implant handpiece. A drive shaft is movably installed through the lower end of the implant handpiece, near the motor. The upper end of the drive shaft is connected to the output end of the motor. A rinsing mechanism is installed between the drive shaft and the implant handpiece. A drill bit is installed at the lower end of the drive shaft. The rinsing mechanism includes a temporary storage tank located inside the implant handpiece, near the motor. A liquid inlet pipe is installed through the implant handpiece, with its end near the motor connected to the temporary storage tank. The end of the liquid inlet pipe away from the motor is connected to an external implant machine. A pressing groove is provided on the lower inner surface of the temporary storage tank. A movable groove is provided at the lower inner end of the pressing groove. An installation groove is provided through the lower inner end of the movable groove. A rotating ring is engaged inside the installation groove. Several drain pipes are installed through the rotating ring, each with a nozzle installed at its lower end. The rotating ring is connected to the drive shaft.

[0007] Preferably, bearings are installed at both ends of the mounting groove, and the inner and outer sides of the rotating ring are respectively in contact with the bearings.

[0008] Preferably, pressure rings are installed at both ends of the inner cavity of the pressing groove, and several bolts are threaded between the pressure rings and the pressing groove.

[0009] Preferably, movable rings are installed on the inner and outer sides of the upper end of the rotating ring, and the movable rings are engaged between the pressure ring and the movable groove.

[0010] Preferably, an extension ring is mounted on the lower surface of the rotating ring, and an extension plate is mounted on the upper end of the shaft of the drive shaft, with the extension ring and the extension plate connected together.

[0011] Preferably, several transmission plates are bolted to the lower surface of the extension plate and the extension ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) By setting up a rinsing mechanism, the rinsing operation can be carried out without the need for additional medical staff to hold the water pipe. The external implant machine can transport the rinsing liquid to the storage tank through the inlet pipe, and then spray it directly from the nozzle to the contact area between the drill bit and the gum through the outlet pipe. This realizes the synchronous automation of drilling and rinsing, reduces the manpower input, and avoids the instability problem caused by holding the water pipe. It ensures that the water flow can accurately and continuously act on the target area, effectively protects the clarity of the surgical field, and improves the overall stability of the dental implant processing process.

[0014] (2) When the drive shaft drives the drill bit to rotate under the drive of the motor, the extension plate, the transmission plate and the extension ring can drive the rotating ring and the drain pipe and nozzle installed on the rotating ring to rotate synchronously. The rotating nozzle can spray water in all directions without dead angles on the drilling area, which greatly expands the rinsing range and speeds up the cleaning speed of bone fragments and tissue residues. At the same time, the continuous and comprehensive water flow contact can more efficiently remove the heat generated by the friction between the drill bit and the gum, avoid the local temperature from being too high and causing damage to the surrounding tissues, significantly improve the cooling effect and rinsing efficiency, and further ensure the safety of dental implant surgery.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1 to 7 As shown in the figure, this utility model embodiment proposes an automatic rinsing dental implant drill, including an implant handpiece 1. A motor 4 is installed at one end of the implant handpiece 1. A drive shaft 5 is movably installed through the lower end of the implant handpiece 1 and near the motor 4. The upper end of the drive shaft 5 is connected to the output end of the motor 4. A rinsing mechanism 3 is installed between the drive shaft 5 and the implant handpiece 1. A drill bit 2 is installed at the lower end of the drive shaft 5. The rinsing mechanism 3 includes a temporary storage tank 302, which is located inside the implant handpiece 1 and near the motor 4. A liquid inlet pipe 3 is installed through the inside of the implant handpiece 1. 01. The end of the inlet pipe 301 near the motor 4 is connected to the temporary storage tank 302. The end of the inlet pipe 301 away from the motor 4 is connected to the external planting machine. The lower inner surface of the temporary storage tank 302 is provided with a pressing groove 303. The lower inner end of the pressing groove 303 is provided with a movable groove 304. The lower inner end of the movable groove 304 is provided with a mounting groove 305. A rotating ring 306 is fitted inside the mounting groove 305. Several drain pipes 307 are installed inside the rotating ring 306. The lower end of the drain pipes 307 is respectively installed with a nozzle 308. The rotating ring 306 is connected to the drive shaft 5.

[0025] like Figure 6 and Figure 7 As shown, in another embodiment of the present invention, bearings 309 are respectively installed at both ends of the mounting groove 305, and the inner and outer sides of the rotating ring 306 are respectively in contact with the bearings 309. Pressure rings 311 are respectively installed at both ends of the pressing groove 303. Several bolts are threadedly installed between the pressure rings 311 and the pressing groove 303. Movable rings 310 are respectively installed on the inner and outer sides of the upper end of the rotating ring 306. The movable rings 310 are engaged between the pressure rings 311 and the movable groove 304. An extension ring 312 is installed on the lower surface of the rotating ring 306. An extension plate 313 is installed on the upper end of the shaft of the transmission shaft 5. The extension ring 312 and the extension plate 313 are connected. Several transmission plates 314 are bolted to the lower surface of the extension plate 313 and the extension ring 312.

[0026] When the external implant machine is started, the motor 4 inside the implant handpiece 1 starts working. The output end of the motor 4 drives the drive shaft 5 to rotate, and the drive shaft 5 in turn drives the drill bit 2 at the lower end to rotate at high speed to drill holes in the gingival tissue. Then, the external implant machine delivers the rinsing solution to the temporary storage tank 302 through the inlet pipe 301. The rinsing solution in the temporary storage tank 302 flows into the drain pipe 307 on the rotating ring 306, and is finally sprayed between the drill bit 2 and the gingiva through the nozzle 308. At the same time, when the drive shaft 5 rotates, the rotating ring 306 is driven to rotate synchronously through the linkage of the extension plate 313, the drive plate 314 and the extension ring 312, so that the drain pipe 307 and the nozzle 308 on the rotating ring 306 rotate accordingly, realizing all-round water spraying of the drilling area.

[0027] The temporary storage tank 302 can temporarily store the rinsing fluid, ensuring a continuous and stable supply of the rinsing fluid and preventing water flow interruption from affecting the rinsing effect;

[0028] The connection design between the inlet pipe 301 and the external planting machine enables automatic delivery of the rinsing solution, eliminating the need for manual addition and saving manpower.

[0029] The installation of the pressure ring 311 and the bearing 309 serves to limit and support the rotating ring 306, ensuring smooth rotation of the rotating ring 306, reducing frictional loss, and extending the service life of the equipment.

[0030] The snap-fit ​​installation of the movable ring 310 enhances the stability of the rotating ring 306 during rotation and prevents the rotating ring 306 from shifting, which would cause the nozzle 308 to spray inaccurately.

[0031] The linkage structure of the extension ring 312, extension plate 313 and transmission plate 314 enables the synchronous rotation of the transmission shaft 5 and the rotating ring 306, ensuring that the nozzle 308 rotates synchronously with the drill bit 2, and ensuring that the flushing range is completely matched with the drilling area.

[0032] The working principle of this self-rinsing dental implant drill:

[0033] In use, the external implant machine is first started, and at the same time, the motor 4 inside the implant handpiece 1 starts working. The output end of the motor 4 drives the drive shaft 5 to rotate, and the drive shaft 5 in turn drives the drill bit 2 at the lower end to rotate at high speed to drill holes in the gingival tissue. Then, the external implant machine delivers the rinsing solution to the temporary storage tank 302 through the inlet pipe 301. The rinsing solution in the temporary storage tank 302 flows into the drain pipe 307 on the rotating ring 306, and is finally sprayed between the drill bit 2 and the gingiva through the nozzle 308. At the same time, when the drive shaft 5 rotates, the rotating ring 306 is driven to rotate synchronously through the linkage of the extension plate 313, the drive plate 314 and the extension ring 312, so that the drain pipe 307 and the nozzle 308 on the rotating ring 306 rotate accordingly, realizing all-round water spraying of the drilling area.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
