Embodiment Construction

[0015] figure 1 It is a three-dimensional view of a hand-operated craniotomy drill in the prior art. From figure 1 It can be seen that since it does not have any depth-limiting means, the mastery of the depth depends entirely on the doctor's feeling and skills during craniotomy and drilling, so it is extremely unfavorable for interns and junior doctors to use. And because the thickness of the skull of each patient is different or the anatomy is different, such as the degree of softness and hardness of the bone, even a skilled neurosurgeon may cause a threat to the safety of the patient due to sensory deviation or excessive force for various reasons .

[0016] figure 2 It is a perspective view of the hand-operated craniotomy drill of the present invention, wherein the hand-operated craniotomy drill with depth-limiting device of the present invention is illustrated, and the hand-operated craniotomy drill consists of a drill bit (1), a thread (2), a drill body (3), consistin...

Abstract

The invention relates to a hand craniotomy drill with a depth limiting device. The hand craniotomy drill comprises a drill bit (1), a thread (2), a drill body (3), a drill body connecting portion (4) and a nut (5). The hand craniotomy drill has the advantages that the operation is simple, the usage is convenient, besides, drilling depth for a cranial bone can be adjusted according to the thickness of the cranial bone of a patient, the use cost is low, and the safety for usage is remarkably improved.

Description

technical field [0001] The invention relates to a hand-operated craniotomy drill for neurosurgical craniotomy, which is equipped with a depth-limiting device, which can adjust the depth of the skull drill according to the thickness of the patient's skull. Background technique [0002] In neurosurgery craniotomy, the craniotomy drill is a must-use instrument. At present, the craniotomy drills used include electric, pneumatic and hand-operated, among which the hand-operated is the most commonly used. The advantages of the hand-operated craniotomy drill are simple structure, easy operation, and low usage cost, so it is widely used. The main disadvantage of hand drills is low safety. After drilling through, under the pressure and inertia of the handle, the drill bit may go deep into the brain, easily damaging the dura mater and brain tissue. [0003] Therefore, there is a need for a hand-operated craniotomy drill that can freely control the drilling depth according to the patie...
