Abstract
The utility model provides a drill bit depth controller, which comprises a controller body and is characterized in that the controller body consists of an inner ring and a movable outer ring, wherein the inner ring is movably connected with the movable outer ring; the upper end of the inner ring is higher than the upper end of the movable outer ring, and the lower end of the inner ring is higher than the lower end of the movable outer ring; and the upper end of the inner ring, which is higher than the movable outer ring, is provided with a drill chuck. Before operation is conducted, the controller body is sleeved on a drill bit, the thickness of the skull of a patient is measured according to a CT (computerized tomography) radiograph or an X-ray radiograph of the skull of the patient, then the length of the drill bit is measured by using a ruler according to the depth required to be drilled, and the controller body is fixedly arranged on the drill bit by using the drill chuck arranged at the upper end of the inner ring, so as to control the drilling depth and the safety of the patient. The drill bit depth controller has the beneficial effects that either beginners or inexperienced personnel can control the drilling depth and guarantee the safety of the patient when using the drill bit depth controller.
Description
Technical field
This utility model relates to a kind of auxiliary medical apparatus, specifically a kind of bit depth controller.
Background technology
At present, the patient of known spinal column clinically section often can use skull traction in therapeutic process.When carrying out skull traction, need hole at patient's skull, lay the skull traction bow.In clinical position, what use at present is common skull drill bit, and it does not have the dark device of insurance limit, can't guarantee drilling depth in the use, especially abecedarian or the personnel that lack experience in use can occur cranial drill saturating, the situation of damage cranium cerebral tissue, abnormally dangerous.Brought inconvenience for medical worker's work.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, bit depth controller easy to use.
The technical scheme that its above-mentioned technical problem that solves this utility model adopts is: a kind of bit depth controller, it comprises body, it is characterized in that: described body is made up of internal ring and movable outer shroud, internal ring connects with movable outer shroud is movable, the internal ring upper end is higher than movable outer shroud upper end, the internal ring lower end is higher than movable outer shroud lower end, and the upper end that internal ring is higher than movable outer shroud is provided with drill chuck.Before operating, described body is set on the drill bit, according to the CT sheet of patient's skull or the thickness that X-ray film is measured patient's skull, then as required boring the degree of depth, length with the good drill bit of dipstick metering, drill chuck with the internal ring upper end is provided with is fixed on described body on the drill bit, with the keyhole degree of depth and patient's safety.
The beneficial effects of the utility model are: no matter be abecedarian or the personnel that lack experience, and in use can both the keyhole degree of depth and the safety that guarantees the patient.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is overall structure sketch map of the present utility model.
Among the figure: 1. body, 2. internal ring, 3. movable outer shroud, 4. drill chuck.
The specific embodiment
In the drawings, a kind of bit depth controller, it comprises body 1, it is characterized in that: described body 1 is made up of internal ring 2 and movable outer shroud 3, internal ring 2 and movable 3 movable connections of outer shroud, internal ring 2 upper ends are higher than movable outer shroud 3 upper ends, and internal ring 2 lower ends are higher than movable outer shroud 3 lower ends, and the upper end that internal ring 2 is higher than movable outer shroud 3 is provided with drill chuck 4.Before operating, described body 1 is set on the drill bit, according to the CT sheet of patient's skull or the thickness that X-ray film is measured patient's skull, then as required boring the degree of depth, length with the good drill bit of dipstick metering, drill chuck 4 with internal ring 2 upper ends are provided with is fixed on described body 1 on the drill bit, with the keyhole degree of depth and patient's safety.
