Technical Field

[0001] This utility model relates to the field of dental instrument technology, specifically to a drill for dental implantation. Background Technology

[0002] During dental implant surgery, holes need to be drilled into the patient's alveolar bone to insert the implant. Currently, dental implant drills inevitably produce bone fragments during the drilling process. To ensure a clear surgical field, the work area is usually rinsed with water. However, with existing drills, bone fragments and water splash during rinsing, which can easily enter the patient's mouth, causing discomfort.

[0003] The main solution to this problem currently is to use an external water-absorbing structure to quickly remove the flushing water. However, this method has limited effectiveness and cannot fundamentally prevent splashing. Furthermore, the surgeon needs to precisely control the angle of the drill during the procedure, requiring a high level of skill and increasing the difficulty of the surgery. Current patents primarily focus on optimizing the drill bit structure to reduce splashing, but they do not effectively address the issue of bone fragments and water splashing during flushing. Summary of the Invention

[0004] The purpose of this invention is to provide a dental implant drill to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides a dental implant drill, including a handle and a drill head. The drill also includes a water spray assembly, which is located at the end of the handle and on the outside of the drill head. The water spray assembly includes an annular base and an annular cover. The annular base is located at the end of the handle, and the annular cover is connected to the annular base via a spiral structure. The annular base is annular in structure with a central through hole for the drill head to pass through. The top of the annular base has a base groove with a flushing fluid inlet. The annular cover is cap-shaped with threads on its inner wall, which mate with the threads on the outer wall of the annular base. The annular cover has an inclined surface near the axis of the drill head, and several flushing micro-holes are provided on the inclined surface. The top of the annular cover has several evenly distributed water curtain outlets.

[0006] Furthermore, a base protrusion is provided on the outer side of the top of the annular base, and a base groove is provided on the top surface of the base protrusion.

[0007] Furthermore, the ring cover has a ring cover protrusion at the position corresponding to the base protrusion, and the top of the base protrusion extends into the interior of the ring cover protrusion.

Detailed Implementation

[0015] 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.

[0016] As attached Figure 1-5As shown, the dental implant drill involved in this utility model includes a handle 1, a drill head 2, and a water spray assembly 3.

[0017] Among them, the water spray component 3 is the core improvement of this utility model. Through the dual-outlet water design, it achieves efficient flushing of the drill bit working area and effective blocking of bone fragments splashing.

[0018] Handle 1, the part held by the doctor, contains a drive mechanism, water supply pipe, and control circuit. Drill head 2, including drill bit holder and drill bit, is used for drilling into the alveolar bone. The specific structure of handle 1 and drill head 2 follows existing products in the field, and their specific structure and connection relationship are not protected by this application.

[0019] The water spray assembly 3 is located at the end of the handle part 1, outside the drill head 2, and includes an annular base 31 and an annular cover 32.

[0020] As attached Figure 2 As shown in Figures 3 and 4, the annular base 31 is disposed at the end of the handle portion 1, and the annular cover 32 is connected to the annular base 31 by a spiral structure.

[0021] The annular base 31 has an annular structure with a through hole in the center for the drill head 2 to pass through. A base protrusion 310 is provided on the outer side of the top of the annular base 31. A base groove 311 is provided on the top surface of the base protrusion 310. The base groove 311 is provided with a flushing fluid inlet, which is connected to the water supply pipe inside the handle part 1. The flushing fluid can enter the base groove 311 through the flushing fluid inlet.

[0022] The ring cover 32 has a cap-like structure with threads on its inner wall, which mate with the threaded structure on the outer wall of the annular base 31. A ring cover protrusion 320 is provided on the ring cover 32 at the position corresponding to the base protrusion 310. The top of the base protrusion 310 extends into the interior of the ring cover protrusion 320, and the watertightness of the contact area is achieved by controlling the size or by setting an O-ring or threaded structure.

[0023] The ring cover 32 has a through hole in the center for the drill head 2 to pass through. Furthermore, to improve structural stability, a fixing ring is provided at the through hole of the ring cover 32. The drill head 2 passes through the fixing ring, and the fixing ring is connected to the inner hole of the annular base 31 by a threaded structure.

[0024] The ring cover protrusion 320 has an inclined surface near the axis of the drill bit 2. Several flushing microholes 321 are provided on the inclined surface. The flushing microholes 321 are arranged in a 360-degree circumferential array. Due to the existence of the inclined surface, the water flow will be inclined towards the drill bit, thereby achieving flushing of the drill bit working area.

[0025] The inclined surface is set in the upper part of the ring cover protrusion 320, and the lower part should be parallel to the inner side wall of the ring cover protrusion 320 to ensure its water tightness.

[0026] The top of the ring cover protrusion 320 is provided with several evenly distributed water curtain outlet holes 322. The flushing liquid flows out through the water curtain outlet holes 322 to form a water curtain that is perpendicular to the ring cover protrusion 320 and parallel to the drill bit.

[0027] The base groove 311 of the annular base 31 and the inner side of the ring cover protrusion 320 form an annular water tank. After the flushing fluid enters the annular water tank from the pipe of the handle part 1, it is divided into two paths: one path directly flushes the drill tip through the flushing micro-hole 321, and the other path forms an annular water curtain through the water curtain outlet hole 322.

[0028] Furthermore, the water curtain outlet holes 322 can be distributed in a 360-degree range, or as shown in the attached figure. Figure 5 As shown, the water curtains are distributed within a 180-degree range, forming either complete annular water curtains or water curtains of approximately 180 degrees. Since the ring cover 32 and the annular base 31 can rotate relative to each other, the area of ​​the water curtain can be adjusted when the water curtain range is 180 degrees.

[0029] The flushing micro-hole 321 is a round hole, as shown in the attached image. Figure 2 As shown in Figures 5 and 6, the water curtain outlet 322 can be a round hole or a narrow slit hole, and can be processed by laser drilling.

[0030] During operation, after starting the drill, the drill head 2 rotates at high speed to drill a hole. Simultaneously, flushing fluid is injected into an annular water tank through a pipe in the handle 1. A portion of the fluid is precisely sprayed into the drill bit's working area through flushing micro-holes 321, washing away bone fragments and cooling the drill bit. Another portion of the fluid forms an annular water curtain barrier outside the drill bit through water curtain outlets 322. This water curtain blocks splashing bone fragments and blood while reducing the diffusion of flushing fluid into the patient's oral cavity. The surgeon can adjust the water curtain area by rotating the ring cap 32 to prevent the water curtain from obstructing their view. An external suction device (such as a negative pressure suction tube) can simultaneously remove the flushing fluid mixed with bone fragments from the working area, maintaining a clear surgical field.

[0031] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
