Improved encephalic puncture guiding method and device

Abstract

An improved encephalic puncture guiding method comprises the following steps of 1, puncture planning guidance, wherein 1.1, an encephalic scanning image sequence is loaded, a three-dimensional encephalic model is built, and meanwhile measurement angle correction data are loaded; 1.2, reference points are set, perpendicular reference planes are built in the three-dimensional model; 1.3, a target spot and an entry point are set, the length of a puncture path composed of the target spot and the entry point and the included angle between the puncture path and the reference planes are worked out; the final plan puncturing angle and depth are obtained by correcting the angle correction data; 2, puncture execution, wherein in the step 1.3, when an encephalic coordination system and a ground coordinate system are not consistent, the encephalic coordination system and the ground coordination system are registered by adopting the point registration method based on output data of a gyroscope, and the included angle between the reference planes and the puncture path obtained after registration is automatically worked out. The invention provides an improved encephalic puncture guiding device. The improved encephalic puncture guiding method and device are easy to implement and convenient to operate and facilitate clinical application.

Description

technical field [0001] The invention relates to a guiding method and device for intracranial puncture, which is used for intracranial puncture, belongs to the technical field of medical equipment, and can make the guiding system more practical and convenient in clinical application. Background technique [0002] Intracranial puncture is one of the effective surgical methods for the treatment of intracranial hematoma caused by hypertensive cerebral hemorrhage. Compared with craniotomy, puncture treatment of cerebral hemorrhage has the characteristics of less trauma, safety, reliability, simple operation, and lower price, and its application is becoming more and more extensive. However, the puncture direction angle and puncture depth often need to be determined by the doctor's experience and are greatly affected by human factors. Therefore, the implementation of puncture surgery often requires the use of some expensive and cumbersome navigation equipment, and it also needs to ...
