3D improved multifunctional minimally invasive surgery auxiliary guide plate, design method and operation method

Abstract

The invention belongs to the technical field of 3D minimally invasive surgery equipment, and discloses a 3D improved multifunctional minimally invasive surgery auxiliary guide plate, a design method and an operation method. A puncture guide plate base and an angle-adjustable puncture channel with an angle ruler are designed by taking a puncture point as the center; and the puncture base and the puncture channel are integrated, and a basal ganglia region cerebral hemorrhage and thalamic hemorrhage transfrontal puncture guide plate is determined and printed through a 3D conversion technology. The 3D improved multifunctional minimally invasive surgery auxiliary guide plate comprises the angle-adjustable puncture channel with the angle ruler; and the puncture channel is fixed on the puncture guide plate base. The inner diameter of the puncture channel is 5mm. According to the invention, the 3D improved multifunctional minimally invasive puncture surgery guide plate is designed and prepared by utilizing the 3D printing conversion technology, so that the requirements of a cerebral hemorrhage emergency minimally invasive surgery are met, and the clinical diversified requirements are met.

Description

technical field [0001] The invention belongs to the technical field of 3D minimally invasive surgery equipment, and in particular relates to a 3D improved multifunctional minimally invasive surgery auxiliary guide plate, a design method and an operation method. Background technique [0002] At present, the anatomical location of the basal ganglia and thalamus is at the 4-6cm level on the OM line of the CT image. [0003] The minimally invasive puncture plane for basal ganglia cerebral hemorrhage and thalamic hemorrhage is this plane. At present, transfrontal puncture is more commonly used, which is safe and suitable for operation, and the effect is good.

AI Technical Summary

Problems solved by technology

[0007] Minimally invasive surgery for cerebral hemorrhage requires free-hand puncture, which is not guaranteed to be accurate, especially for thalamic hemorrhage. Inaccurate puncture will lead to poor results and even re-injury

[0008] Neuronavigation can guarantee the accuracy of minimally invasive puncture, but it is expensive, and most primary hospitals do not have this condition; neuroendoscope-assisted hematoma evacuation can partially solve such problems, but there are also clinical problems such as slightly larger trauma, expensive equipment, and technical requirements. Higher and younger doctors cannot fully grasp the implementation

[0009] The transformation of 3D printing technology, individualized printing assisted guide plate assisted minimally invasive puncture surgery can effectively guarantee the accuracy of the operation, but the preparation of the guide plate requires a certain amount of preparation time. Individualized applications cannot meet diverse needs
