Minimally invasive tooth implanting surgical drill

Abstract

The invention discloses a minimally invasive tooth implanting surgical drill, which comprises a directional perforating head, a first broaching section, a second broaching section, a main body broaching and sizing section, a scale section and a locking section connected sequentially, wherein the directional perforating head has a conical structure; the first broaching section has a frustum-shaped structure, and the diameter of the small end of the first broaching section is as same as that of the conical bottom of the directional perforating head; the second broaching section has a cake-shaped structure, and the diameter of the second broaching section is greater than that of the big end of the first broaching section; the main body broaching and sizing section has a spiral cylindrical structure, and the diameter of the main body broaching and sizing section is greater than that of the second broaching section; and the diameters of the scale section and the locking section are smaller than the diameter of the main body broaching and sizing section. The minimally invasive tooth implanting surgical drill is simple in structure, convenient, practical and easy to make, requires little high-precision machining, and is beneficial to popularization; and skeletal fragments can be used for bone transplantation.

Description

technical field [0001] The invention relates to medical instruments, in particular to a minimally invasive dental implant surgery drill. Background technique [0002] At present, the two-stage implant model characterized by incision and lifting of the periosteum is still the mainstream method of dental implant surgery at home and abroad. This kind of dental implant method needs alveolar mucoperiosteotomy. The intraoperative trauma is large, there is a lot of bleeding, and the vision is blurred. The operation time is long and the postoperative reaction is large. Minimally invasive dental implant technology allows doctors to perform precise surgery without having to cut the gums. Compared with the traditional flap implant surgery, the minimally invasive dental implant surgery combined with 3D computer scanning positioning technology or aimer positioning technology pays more attention to the protection of the lesion area and its surrounding tissues, minimizes trauma, avoids or...

Problems solved by technology

However, the area of ​​direct contact between the traditional surgical drill and the hole wall is large, which requires many places for high-precision machining, which brings a lot of inconvenience to mass production

Finally, due to the existence of rib grooves in traditional surgical drills, the walls of the drilled bone holes are not very smooth, and cracks may occur in some places with different bone densities, which is also a major reason for poor surgical results.
