Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a medical electric bone drill. Background Art

[0002] In medical operations such as orthopedic surgeries, drilling operations are often required. Traditional medical electric drills usually come with a single drill bit. However, with the development of medical technology and the increasing demand for surgical refinement, the limitations of such single-bit electric drills in terms of efficiency and accuracy have gradually emerged.

[0003] Currently in clinical practice, when multiple holes need to be drilled in bone tissue, doctors need to operate the electric drill multiple times, frequently adjusting the drilling position and angle. This not only consumes a large amount of surgical time but also may result in error accumulation due to multiple positioning, affecting the drilling accuracy and thus having an adverse impact on the surgical outcome.

[0004] Therefore, developing a medical electric drill with a simple structure, convenient installation, and capable of simultaneously and efficiently drilling with multiple drill bits has important clinical application value and broad market prospects. Summary of the Invention

The drill bit assembly is detachably installed on the drill body. The drill bit assembly includes a base and at least two mounting fittings. At least two mounting positions are provided on the base, and each mounting fitting is adapted to one mounting position. The mounting fittings are adjustable in position on the mounting positions. The mounting fittings are used to mount drill bits. When the mounting fittings are adjusted on the mounting positions, the positions between adjacent drill bits are adjustable.

[0007] In some embodiments, the base is of a circular structure, a rotating hole is provided in the middle of the base, the rotating shaft of the drill body is matched with the rotating hole, the mounting positions are circumferentially arranged outside the rotating hole, the rotating shaft is detachably installed with the rotating hole, and after the rotating shaft is matched with the rotating hole, it drives the base to rotate.

[0008] In some embodiments, the mounting position is of an arc-shaped groove structure, and the centers of multiple arc-shaped groove structures are the same.

[0009] In some embodiments, the mounting position is of a rectangular groove structure, and a target angle is formed between adjacent two rectangular grooves.

[0010] In some embodiments, there are three mounting positions of the rectangular groove structure, and the three mounting positions form a triangular structure.

[0011] In some embodiments, the base is a rectangular structure, and at least two mounting positions are sequentially arranged at intervals along the length direction of the base of the rectangular structure.

[0012] In some embodiments, the medical electric bone drill further includes a plurality of meshing gears, each meshing gear is adapted to a mounting position, and each fitting gear is slidably arranged on the corresponding mounting position.
