Automated skull drilling mechanism

Abstract

The invention discloses an automated skull drilling mechanism. A base of the automated skull drilling mechanism is provided with a force detection unit which is connected with a computer of a core control device through a circuit, so that the base can be combined to the front end of a multiaxial type robot arm; accordingly, the computer controls the mutliaxial type robot arm to move a drill endpoint to point to a set coordinate, the automated skull drilling mechanism at the front end of the multiaxial type robot arm begins to start drilling, the computer controls the multiaxial type robot arm to move to the coordinate to be fed to or cut off; when the force detection unit detects that pressure changes due to drilling through, a signal is transmitted to the core control device through a circuit, and the core control device stops the feeding of the multiaxial type robot arm at the first time so as to ensure that meninx is not damaged; and the automated skull drilling mechanism is also relatively steady to hold.

Description

technical field [0001] The invention relates to the technical field of a skull drilling machine, in particular to provide an automatic skull drilling mechanism technically. Background technique [0002] Press, when a patient develops Parkinson's disease, brain tumor, or part of the brain tissue needs to be taken out for pathological examination, the location of the symptom is usually determined by MRI or CT first, and then in the patient A round hole with a diameter of about 6mm is drilled in the skull, and the doctor inserts a probe or instrument with a diameter of about 2mm into the brain tissue for laser ablation treatment or removes part of the brain tissue for pathological examination. Among them, the lower layer of the skin of the human brain is the skull of hard tissue, and the lower part of the skull is the dura mater, arachnoid membrane, and pia mater in sequence, in which countless blood vessels shuttle to supply the brain with nutrition. Therefore when carrying o...

Problems solved by technology

In addition, it is known that a special electric drill is designed with a set of safety devices. When the active part (motor) and the passive part (drill bit) similar to the clutch mechanism are under pressure, they will closely cooperate to drive the drill bit to operate to drill the skull. When the drill bit penetrates the skull , the active part is separated from the passive part because it no longer bears the reaction force of the skull, causing the electric drill to stop operating

[0004] However, these methods must rely on the doctor's personal rich clinical experience and hand feeling to judge whether the skull has been drilled through the skull and stop manually; Inadvertently, it is possible to injure the meninges and nerve tissues below the skull while passing through the skull

In addition, when drilling with bare hands, vibration may occur during the drilling process due to insufficient arm strength, which affects the safety, accuracy and comfort of the drilling process

[0005] The technical problem to be solved is: if drilling a round hole or cutting the skull is made of general materials, then there is no need to pay more attention to the situation after it is drilled through, but if it is used to drill the human brain, there will be holes immediately after the hard tissue. The meningeal tissue and nerve tissue cannot be mistaken. However, the current drilling method requires the doctor to hold the tool to drill the hole. The stability is not good, and whether the drilling is done depends on the doctor's hand to stop the drilling. It is too dangerous to put patients in a disadvantaged position, and it is also prone to medical disputes
