Description

Dental drill

The present invention relates to a "dental drill" that can collect the bone debris after drilling to the greatest extent.

Teeth are a part of the digestive system. It is mainly used to cut, chew, and grind food during a series of actions before eating the food smoothly, and the teeth also have a good appearance. , Help pronunciation and other functions, so teeth are really one of the vital organs indispensable to the human body.

However, it is believed that many people will have problems such as tooth-related diseases that cause their original teeth to no longer be available for use, or tooth loss due to collisions. If this happens, it is often necessary to use artificial dental implants in the oral cavity. (The dental implant is used to replace the root of the original tooth after extraction). During the implantation process, the dentist will connect a dental bone drill with a surgical instrument (drill). The dental bone drill drills the alveolar bone of the affected part in the patient's oral cavity, and can facilitate the implantation and lock of the dental implant on the alveolar bone after drilling.

However, the above-mentioned conventional structure still has the following problems in practical applications: whether the dental bone drill is a twist drill or a straight flute drill, it does not have the ability to make the bone debris from the drill. The function of proper collection makes it easier for the bone debris to be washed away by the water flow during drilling Loss occurs. When the patient’s alveolar bone shrinks due to periodontal disease or missing teeth for too long, and it is necessary to take the patient’s autologous bone for the bone repair procedure, it often happens that there is not enough autologous bone debris available for use. The problem is that the implantation of autologous bone debris cannot be replaced by other alternative materials because it has a good effect of promoting proliferation. Therefore, it is really necessary to improve and innovate breakthroughs.

Therefore, the inventor of the present invention is in view of this, thinking and creating ideas, so he designed with many years of experience, and after many discussions and trial samples, and many modifications and improvements, he came up with the present invention.

No matter the conventional dental bone drill is a twist drill or a straight flute drill, it does not have the function of properly collecting the bone debris from the drilling. This is the technical problem to be solved.

The dental bone drill of the present invention includes: a dental bone drill body and a collecting cover, wherein the dental bone drill body has a first blade and a second blade made by stamping technology, the second blade A blade is formed on both sides of a blade plate and a second blade plate, and the center of the first blade plate is penetrated with a straight insertion hole, and the straight insertion hole is used to provide one side of the second blade plate to penetrate again. Extending outwards, the first blade and the second blade can complete the set in a crisscross shape with four bone debris receiving grooves. After the set, the first blade and the second blade are welded by laser The first blade and the second blade are welded together so that The first blade and the second blade can jointly form a drill body with a drilled tip at the bottom end, and a drill shank is connected to the top end of the drill body, and the drill shank is close to the drill body A ring groove is provided below to provide the collection cover as a sleeve. The collection cover has a closed end and a ring wall. The closed end and the ring wall are surrounded by the connection between the closed end and the ring wall to form the inside of the collection cover. There is an accommodating space, and the lower part of the accommodating space is open, and a set of holes is provided in the center of the closed end, and the drill shank is provided through the set of holes, and then the hole edge of the set of holes is inserted into the drill The positioning in the ring groove of the shank enables the collection cover to be smoothly installed on the drill shank. By using the downward extension of the ring wall, the entire ring wall can be used to cover the outer side of the upper section of the drill body. In addition, the bottom surface of the closed end is provided with four slits arranged in a cross shape and four groups of scraping parts composed of two-by-two spaced scraping strips. The slits are provided between the sleeve hole and the scraping part. , And is connected to the sleeve hole, but does not penetrate the top surface of the closed end upward, so that the slit can be fully expanded when the collection cover is pushed down. The two scraping strips of the scraping part are respectively attached to the two surfaces of each of the first blade and the second blade, so that when the collection cover is pushed down, the scraping strips can be used The bone debris attached to the first blade and the second blade are scraped down, so that the dental bone drill body can make the most proper and complete bone debris after drilling. Collection, to avoid excessive loss of the bone debris, resulting in inadequate use; thereby, it can constitute the dental bone drill.

(1) The dental bone drill of the present invention uses the collecting cover to cover the drill body of the dental bone drill body, so that the bone debris obtained by drilling can be retained to the greatest extent. Take the bones When the bone repair procedure is performed, there will be no trouble of insufficient bone debris for application.

(2) In the dental bone drill of the present invention, after the bone debris is collected, it can be obtained quickly, conveniently and completely by using the downward movement of the collecting cover, so that the collection of bone debris will no longer be a hassle Difficult things.

(3) In the dental bone drill of the present invention, the first blade and the second blade are combined by stamping and then welding, which has the characteristics of convenient processing, low production cost, and good structural strength. The straight fluted dental bone drill made by traditional electric discharge machining has more competitive advantages in the industry.
