Orthopedic-screw guiding positioning forceps

Abstract

The invention relates to orthopedic-screw guiding positioning forceps, and belongs to a tool used in the medical field. The orthopedic-screw guiding positioning forceps are characterized by comprisinga first forcep body and a second forcep body, an included angle of 120 degrees to 150 degrees is formed between the front ends of the first forcep body and the second forcep body and the back ends ofthe first forcep body and the second forcep body, the first forcep body is hinged to the second forcep body at the back end of the position of the included angle, the inner side faces of the clampingfront ends of the first forcep body and the second forcep body are each provided with an arc inner groove, and the inner grooves of the two forcep bodies are opposite to form a circle; at least two rotatable rolling shafts are arranged on the side face of the inner groove of each forcep body, rotating shafts of the rolling shafts are arranged on the side face of each forcep body, faces passed when center shafts of the rolling shafts and the front ends of the forcep bodies are open and closed and swing are perpendicular, and threads are formed in the surfaces of the rolling shafts; after the front end of the first forcep body is engaged with the front end of the second forcep body, the rolling shafts are in contact with the outer surface of an orthopedic screw, clamping force is applied tothe orthopedic screw in at least four directions, the rolling shafts are distributed at equal angle on the circle formed by the inner grooves, the orthopedic screw rotates, and the rolling shafts rotate along with the orthopedic screw.

Description

technical field [0001] The invention relates to an orthopedic screw guiding and positioning forceps, belonging to a tool used in the medical field. Background technique [0002] At present, when screwing in screws clinically in orthopedics, especially when the operating space is narrow, nail holders are often used instead of hands to hold the screws, which include left handles and right handles. The rear parts of the rods are respectively connected with tooth-shaped fixing cards, and the front ends of the two connecting rods are respectively equipped with jaws, each jaw is bent inwards to form a semicircle, and the two jaws form a circle after closing; the left handle connects the jaws of the front end of the rod Combined with the jaws at the front end of the connecting rod on the right handle, it just forms a circle, which can fix the nails in the jaws. Use the nail holder to hold the nails firmly without slipping. Difficult to operate problem. At the same time, avoid t...
