Problems solved by technology
[0004] The object of the present invention is to provide an orthopedic drilling tool with controllable screwing distance, to solve the above-mentioned background technology. During the use of the orthopedic drilling tool, the doctor needs to hold the drilling tool with both hands, and screw the drill bit into the patient. Slight shaking of the doctor's hand will cause the drilling to deviate from the original track, and if the drilling tool is fixed, it will be inconvenient to adjust the direction, and the adjusted drilling tool cannot be locked

The orthopedic drilling tool comprises a feeding plate, a connecting rod is connected to the lower portion of the feeding plate, a rotating rod is arranged below the connecting rod, a limiting clamping groove is formed in the middle of the rotating rod, and a bottom fixing suction cup is installed below the rotating rod; the locking gear is arranged on the outer portion of the connecting rod in a sleeving mode, a self-locking gear ring is installed on the outer portion of the locking gear, a connecting block is fixed to the outer portion of the self-locking gear ring, and a rotating inner ring is installed on the outer portion of the connecting block; and the arc-shaped plate is arranged below the rotating inner ring. According to the orthopedic drilling tool with the controllable screw-in distance, a transmission gear can drive an arc-shaped plate to rotate in a rotating rod through a transmission gear ring, so that a rotating inner ring is integrally unlocked, rotation of the rotating inner ring is completed, and the rotating inner ring can be reset under the action of a pushing plate; and the rotating inner ring is locked through friction between an arc-shaped plate and a limiting clamping groove, and the feeding plate is prevented from sliding after angle adjustment is completed.
Description
technical field [0001] The invention relates to the technical field of orthopedic drilling tools, in particular to an orthopedic drilling tool with controllable screw-in distance. Background technique [0002] Orthopedics is also known as orthopedics. It is a profession or discipline of medicine that specializes in the study of the anatomy, physiology and pathology of the musculoskeletal system, the use of drugs, surgery and physical methods to maintain and develop the normal form and function of this system, and to treat injuries and diseases of this system. Orthopedic instruments generally refer to professional medical instruments specially used for orthopedic surgery. Orthopedic instruments are mainly divided into orthopedic knives, orthopedic scissors, orthopedic forceps, orthopedic hooks, orthopedic needles, orthopedic scrapers, orthopedic Using cones, orthopedic drills, etc., many operations require opening holes in the original bones, and inserting bone screws to rep...
