Skull drill

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a skull drill. The skull drill comprises a supporting table; a round hole is formed in the center of the supporting table; a second mounting frame is fixedly connected to the bottom wall of the supporting table; threaded rods are fixedly connected to the two bottom walls of the second mounting frame; a first mounting frame is movably mounted on one side of the second mounting frame through two threaded rods; the first mounting frame and the second mounting frame are symmetrically arranged; and fastening nuts are spirally mounted at one ends, extending out of the second mounting frame, of the two threaded rods. According to the invention, the position of a drilling machine is adjusted through a rotating mechanism, a supporting frame is driven by a rotating disc to rotate in a circular rail, the position of a movable frame can be adjusted through an arc-shaped rail, and meanwhile, the position of a limiting frame can be adjusted through a horizontal rail, and thus, the skull drill can be convenient for medical staff to adjust the position of the drilling machine and convenient to drill, and meanwhile, the stability of the drilling machine can be improved, so that the drilling precision can be improved, and treatment of a patient is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a skull drill. Background technique [0002] The human skull is composed of 23 bones, which can support and protect important organs such as the brain. The cranium is composed of an outer plate, a barrier, and an inner plate, including the frontal bone, parietal bone, occipital bone, temporal bone, and part of the zygomatic bone and the greater wing of the sphenoid bone. , connected together by the coronal suture, sagittal suture, "person" suture and squamous suture, the inner surface of the calvaria is depressed, and the impression is composed of gyrus, arachnoid granules, venous sinus and meningeal blood vessels, and the base of the skull The inner surface of the bony skull base is uneven, bounded by the sphenoid crest and petrosal crest from front to back, forming a three-level stepped structure, called the anterior, middle, and posterior cranial fossae, and the ce...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned skull drill can control the drilling depth of the drill bit through the precise control of the stroke of the push rod motor and the auxiliary inspection of the pressure sensor, it can avoid the inability to grasp the drilling depth during manual drilling and cause the patient's dura mater and brain tissue to be drilled. Injuries occur, thereby improving the success rate of the operation, but there are still the following disadvantages: the electric drill can only slide back and forth in the same direction on the guide rail, it is inconvenient to adjust the drilling machine to any position on the top of the patient's head, and it takes a lot of time make adjustments
