Improved minimally invasive cranial drill for neurosurgery clinical operation

Abstract

The invention discloses an improved minimally invasive cranial drill for a neurosurgery clinical operation, which comprises a cranial drill main body and a handle arranged at the bottom of the cranialdrill main body, wherein a rotating cavity is formed in a left end of the cranial drill main body; a motor is fixedly arranged in the rotating cavity; and a rotating shaft is fixedly arranged on an output shaft of the motor. By the adoption of the improved minimally invasive cranial drill for the neurosurgery clinical operation, when a drill bit and the skull generate larger vibration in a cranial drill process, the drill bit can carry out buffering movement, so that the drill bit has a good buffering function, the risk of bone cracking caused by overlarge vibration of the drill bit in the cranial drill process is prevented, potential safety hazards are avoided, the drill bit is quickly disassembled and replaced by people, the working difficulty of disassembling and assembling the drill bit by medical personnel is reduced, meanwhile, the drill bit is more stable to install and fix after replacement, and subsequent safe use of the drill bit is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an improved minimally invasive cranial drill for neurosurgery clinical operations. Background technique [0002] Neurosurgery mainly treats diseases of the brain, spinal cord and other nervous systems caused by trauma, such as cerebral hemorrhage that is life-threatening, brain trauma caused by a car accident, or brain tumor compression that requires surgical treatment. [0003] In neurosurgery clinical work, in order to quickly diagnose and treat patients, cranial drilling is often performed on patients. At present, the front cutting edge of the drill used in drilling surgery has a flat pointed structure, twist drill structure, etc., and the drill does not need to be cut with a blade. , Directly use the tip of the flat pointed part to pierce the scalp to directly locate and drill holes on the skull. The operation is simple, convenient, and less traumatic. It can real...

Problems solved by technology

[0004] However, the cranial drill bits in the existing minimally invasive cranial drills are all fixedly installed in the minimally invasive cranial drills. Once the drill bit is damaged, or when the size of the drill bit is changed, it is very inconvenient to disassemble and assemble, which brings difficulty to the medical staff. Moreover, the existing minimally invasive cranial drills for neurosurgery clinical operations do not have a buffer function. If the vibration is too large during the cranial drilling process, it may easily lead to the risk of bone fractures and bring potential safety hazards.
