Auxiliary guiding device for precise puncture of intracranial hematoma based on laser guiding and puncture method

Abstract

The invention provides an auxiliary guiding device for precise puncture of intracranial hematoma based on laser guiding and a puncture method, and relates to the technical field of clinical medicine. According to the invention, preoperative planning is carried out by utilizing an axial position sheet and a sagittal position sheet of the craniocerebral CT of a patient, angles alpha and beta between a puncture path and a set x axis and a set y axis are obtained, and puncture depth is measured; then the guiding device is arranged on the head of the patient, a cross-shaped semiconductor laser on the guiding device is used for simulating a planned x axis and a planned y axis, a double-axis inclinometer arranged in a point-shaped semiconductor laser is used for adjusting the laser to enable an angle between the point-shaped laser and the x axis and the angle between the point-shaped laser and the y axis to be alpha and beta, and at the moment, the emitting direction of the point-shaped laser is a puncture direction; and in a puncture process, a laser focus is continuously arranged at the center of the tail of a puncture needle, and at the moment, the puncture direction of the puncture needle continuously faces the center of the hematoma, so rapid and accurate determination of a needle insertion path is achieved, selection of the needle insertion path is not limited by the subjective opinion of an operator, and rapid and accurate puncture facing the focus is achieved.

Description

technical field [0001] The invention relates to the technical field of clinical medical devices, in particular to a guiding device and a puncturing method for precise puncturing of intracranial hematoma based on laser guidance. Background technique [0002] Hypertensive intracerebral hemorrhage has the clinical characteristics of high morbidity, high mortality and high disability rate. Early elimination of intracerebral hematoma can minimize or eliminate secondary brain damage and play a positive and important role in reducing the disability rate. Significance, especially for elderly (> 60 years old) patients with deep brain hemorrhage, because of their poor tolerance to surgery, it is necessary to use a surgical method that is less invasive, easy to accept, and has a good effect. In recent years, with the rapid development of surgical instruments and materials, minimally invasive surgery for cerebral hemorrhage has gradually attracted attention. After years of developme...

Problems solved by technology

However, the needle insertion process of the above methods all rely on the operator's bare hands, and the puncture accuracy is heavily dependent on the operator's experience and technology, resulting in large errors and poor repeatability.

Moreover, the needle insertion direction of the above-mentioned puncture methods is usually limited to a single CT scan plane, and cross-scan tomographic puncture cannot be performed.
