Abstract

The utility model discloses an alveolar bone exploration bone drill (named as Pan's exploration bone drill), which comprises a drill handle and a drill bit, wherein the tail part of the drill bit is connected with the head part of the drill handle, the drill handle is cylindrical, the tail part of the drill handle is provided with an annular motor bayonet, and the tail end of the drill handle is provided with a motor buckle; the drill bit is a triangular sharp edge structure with a finely polished surface, and the drill bit gradually narrows from the tail of the drill bit to a drill point. Because the bone drill is provided with the triangular sharp edge structure with the finely polished surface, an operator can probe cavities in upper and lower jaw bone tissues by hand feeling when using the bone drill, and the bone drill which is mistakenly inserted into the cavities in the implantation operation to cause implantation failure or damage blood vessel nerve tissues is avoided. Hundreds of years of clinical operations show that the alveolar bone exploration bone drill is safe and reliable, reduces the risk of dental operations and improves the success rate of the operations.

Description

Alveolar bone probing bone drill

Technical Field

The utility model belongs to the technical field of dentistry medical instrument, especially, relate to an alveolar bone explores bone drill.

Background

The CT three-dimensional imaging technique popularizes artificial dental implants to bring benefit to human beings to a new stage, however, because of the complex structures and tissues of maxillary sinus cavities, mandibular nerve canals and the like existing in the jawbone of human body, the safe implantation of implants with sufficient thickness and length in the jawbone by the operators faces huge technical difficulties. Alveolar bone is a part where the root of tooth is embedded in the lower edge of maxilla and the upper edge of mandible, and dental surgery of alveolar bone is also faced with the above-mentioned difficulties.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide an alveolar bone exploration bone drill of exquisite, the convenient to use of structure, excellent effect.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the alveolar bone exploration bone drill comprises a drill handle and a drill bit, wherein the tail part of the drill bit is connected with the head part of the drill handle, the drill handle is cylindrical, an annular motor bayonet is arranged at the tail part of the drill handle, and a motor buckle is arranged at the tail end of the drill handle; the drill bit is a triangular sharp edge structure with a finely polished surface, and the drill bit gradually narrows from the tail of the drill bit to a drill point.

The section of the drill bit is triangular, and three sharp edges of the edge part of the drill bit are in a micro-spiral structure from the drill point to the tail part of the drill bit.

The length of the blade part is 13mm, and the diameter of the thickest position of the tail part of the blade part is 1.2 mm.

The drill handle and the drill bit are integrally formed by grinding a high-strength stainless steel rod.

Aiming at the problem that an effective bone drill tool is lacked in dental operation, the inventor researches and designs an alveolar bone exploration bone drill (named as Pan exploration bone drill) through search and summary for over ten years, wherein the alveolar bone exploration bone drill comprises a drill handle and a drill bit, the tail part of the drill bit is connected with the head part of the drill handle, the drill handle is cylindrical, the tail part of the drill handle is provided with an annular motor bayonet, and the tail end of the drill handle is provided with a motor buckle; the drill bit is a triangular sharp edge structure with a finely polished surface, and the drill bit gradually narrows from the tail of the drill bit to a drill point. Because the bone drill is provided with the triangular sharp edge structure with the finely polished surface, an operator can probe cavities in upper and lower jaw bone tissues by hand feeling when using the bone drill, and the bone drill which is mistakenly inserted into the cavities in the implantation operation to cause implantation failure or damage blood vessel nerve tissues is avoided. Hundreds of years of clinical operations show that the alveolar bone exploration bone drill is safe and reliable, reduces the risk of dental operations and improves the success rate of the operations.

Drawings

Fig. 1 is a schematic structural view of the alveolar bone exploring bone drill of the present invention.

Fig. 2 is a schematic cross-sectional view of the drill bit of the alveolar bone exploration bone drill according to the present invention.

In the figure: 1 drill handle, 2 drill bits, 3 motor bayonets, 4 motor buckles, 5 blade, 6 triangle-shaped.

Detailed Description

As shown in figures 1 to 2, the alveolar bone exploration bone drill of the utility model comprises a drill handle 1 and a drill bit 2, wherein the drill handle and the drill bit are integrally ground and formed by a high-strength stainless steel rod, and the tail part of the drill bit is connected with the head part of the drill handle. Wherein the content of the first and second substances,

the drill handle is cylindrical, the tail of the drill handle is provided with an annular motor bayonet 3, and the tail end of the drill handle is provided with a motor buckle 4, so that the drill handle is conveniently connected with a motor to transmit power.

The drill bit is a triangular sharp edge structure (without a rough coating) with a fine polished surface, and the drill bit gradually narrows from the tail of the drill bit to a drill tip; the section of the drill bit is triangular 6, and three sharp edges of the edge part 5 of the drill bit are in a micro-spiral structure from the drill point to the tail part of the drill bit; the length of the blade part is 13mm, and the diameter of the thickest position of the tail part of the blade part is 1.2 mm.

The alveolar bone exploration bone drill adopts non-manual operation as power, when in use, the tail part of the drill handle is connected with the motor head, and because the drill bit has a fine and smooth triangular sharp edge structure, an operator can sensitively catch a breakthrough feeling when encountering a cavity in the bone drilling process, thereby effectively avoiding the operation risk; meanwhile, the sharp drill bit edge part with a specific size is adopted through screening, so that the bone drill has enough strength and precision, is not easy to break, and can clearly sense the condition of the bone drill, stagger dangerous cavities and fragile tissues to avoid serious damage.
