Description

Technical Field

[0001] The utility model belongs to the field of oral implantology, and particularly relates to an oral implant stop drill. Background Art

[0002] Oral dental implant technology refers to a tooth defect restoration method that supports and retains the upper dental prosthesis based on the lower structure implanted in the bone tissue. It includes two parts: the lower supporting implant and the upper dental prosthesis. An artificial material is used to make the implant, which is implanted into the tissue through a surgical method and obtains firm retention support from the bone tissue, and the upper dental prosthesis is connected and supported through a special device and method.

[0003] According to the Chinese patent with the publication number "CN206365932U", a safety stop drill needle device for dentists' dental implants is disclosed, which includes a drill needle with a stop portion provided thereon, and a stop device is arranged at the lower edge of the stop portion; the external shape of any interface of the stop device is larger than the cross-sectional shape of the drill needle. It mainly adds a stop device at an appropriate position of the drill needle used by dentists for drilling; when the drill needle drills into the tooth or gum and the stop device touches the tooth or gum, the drill needle can no longer drill in, and the drilling can accurately obtain an appropriate depth, so as to achieve the purposes of safe operation, convenient diagnosis and treatment, etc.

[0004] From the above structure, it can be seen that this new type can automatically set the drilling depth to achieve many purposes such as safe operation, increased speed and convenient diagnosis and treatment. However, the stop device of this device is composed of two semi-circular rings that are buckled together and fixed only by mutual extrusion. It is easy to fall off when installed on a high-speed rotating drill needle, resulting in the situation that the falling semi-circular ring accidentally injures the patient. Moreover, when drilling holes of different depths, stop devices of different sizes need to be installed, the operation is cumbersome, and the function of this device is low and it cannot achieve versatility.

[0009] Further, as a preferred technical solution, the other end of the water storage bucket is provided with a water filling port. A rubber cover is inserted inside the water filling port, and a sealing gasket is fixedly connected to the inner side of the rubber cover. The sealing gasket is inserted into the water filling port.

[0010] Further, as a preferred technical solution, a fastening cover is threadedly connected to the outer side of the operating rod. An internal thread is formed on the inner side of the fastening cover, and an external thread is formed on the outer side of the other end of the operating rod. The internal thread and the external thread are threadedly connected to each other. The inner side of the fastening cover is movably connected with the rubber cover.

[0011] Further, as a preferred technical solution, an anti-slip pad is fixedly connected to the outer surface of the operating rod. An extrusion block is fixedly connected to the inner side of the fastening cover, and the extrusion block is movably connected with the rubber cover.

[0012] Further, as a preferred technical solution, a connecting rubber rope is fixedly connected to the outer side of the operating rod.

[0014] In summary, the main beneficial effects of the present utility model are as follows:

[0015] First, through the provided stop component, when adjusting the distance of the drill bit during use, by pushing with a finger on the surface of the adjusting plate, the friction generated between the finger and the adjusting plate when pushing causes the threaded rod to rotate inside the threaded hole. When the threaded rod rotates inside the threaded hole, the threaded rod will slowly extend out of the threaded hole, so that when the threaded rod extends out of the threaded hole, a certain adjustment effect can be achieved on the stop plate, and thus the length of the drill bit can be adjusted. By pushing the adjusting plate forward and backward, the distance of the stop plate can be adjusted up and down. Moreover, the stop component is not directly connected to the drill bit, so it will not affect the normal operation of the drill bit. At the same time, the stop component will not break away while the drill bit is rotating, which increases the safety of the device.

[0016] Second, through the provided water spraying component, when the drill bit drills a hole in the tooth, by starting the air pump, gas is injected into the water storage bucket under the action of the air pump, so that the air pressure inside the water storage bucket is too high, causing the water body to enter the water inlet chamber through the water inlet pipe, then enter the stop plate through the water inlet chamber and finally spray out through the water spraying holes. The inner side of the stop plate is chamfered, so that the sprayed water body sprays downward in a conical shape, so that the drilling part and the drill bit can be sprayed with water. The main purpose of spraying water is to cool the drill bit to prevent it from generating too much heat during high-speed rotation, thereby protecting the tooth and surrounding tissues from thermal damage. At the same time, the water also helps to wash away the debris and bacteria generated during the dental drilling process and keep the oral cavity clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Principle of use and advantages: When in use, first open the fastening cover 15 and then pull out the rubber cover 713. Water can be filled into the interior of the water storage bucket 71 through the water filling port 711. After filling, the rubber cover 713 can be inserted into the water filling port 711, and under the action of the sealing gasket 712, a clamping and sealing effect is achieved. Then, by connecting the fastening cover 15 to the outer side of the operating rod 3, the pressing block 17 contacts and presses the rubber cover 713 during the connection, which can further enhance the sealing effect of the water storage bucket 71 and prevent the rubber cover 713 from being pushed open by gas during use. Then, when adjusting the distance of the drill bit 5, push with fingers on the surface of the adjusting plate 64. When pushing, the friction between the fingers and the adjusting plate 64 causes the threaded rod 63 to rotate inside the threaded hole 62. When the threaded rod 63 rotates inside the threaded hole 62, the threaded rod 63 will slowly extend out of the threaded hole 62. Thus, when the threaded rod 63 extends out of the threaded hole 62, a certain adjustment effect can be achieved on the stop plate 65, and then the length of the drill bit 5 can be adjusted. By pushing the adjusting plate 64 forward and backward, the distance of the stop plate 65 can be adjusted up and down. After the adjustment is completed, the normal equipment can be used. The drill bit 5 is driven by the drill press body 4 to rotate for the teeth. When in use, the air pump 72 is started, and under the action of the air pump 72, gas is filled into the interior of the water storage bucket 71. As a result, the air pressure inside the water storage bucket 71 becomes too high, causing the water body to enter the water inlet chamber 74 through the water inlet pipe 73, then enter the stop plate 65 through the water inlet chamber 74, and finally spray out through the water spray holes 76. The inner side of the stop plate 65 is chamfered, so that the sprayed water body sprays downward in a conical shape, thus enabling the water spraying effect on the drilling part and the drill bit 5. The main purpose of water spraying is to cool the drill bit 5 to prevent it from generating too much heat during high-speed rotation, thereby protecting the teeth and surrounding tissues from thermal damage. And through the set limit sleeve rod 12 and limit movable rod 13, a limiting effect can be achieved on the stop plate 65 to prevent the stop plate 65 from rotating during use.
