Puncture probe for neural navigation

Abstract

The invention relates to a puncture probe for neural navigation. The puncture probe for neural navigation comprises an adapter and a needle puncture needle; the adapter comprises a positioning body and a fixing part; the fixing part is arranged at the bottom of the positioning body; the surface of the positioning body is connected with navigation reflective balls; the length of the puncture needle ranges from 17 mm to 22 mm; and the tail end of the puncture needle is fixedly arranged in the fixing part. The puncture probe has the advantages that the puncture probe is formed by fusing the adapter and the puncture needle, adaptation is only needed once, adaptation data are stored in a navigation system, and adaptation is not needed again in an operation; and the puncture needle serves as the puncture probe and also serves as a catheter guide core, direct puncture can be achieved, repeated adaptation is not needed during multi-tube puncture, the operation process is greatly simplified, the operation time is saved, the system error is reduced to the minimum, the puncture depth of each angle of the head can be considered, puncture deviation caused by displacement of the tail end of the puncture needle due to the fact that the puncture needle is too long and insufficient in hardness is avoided, and the puncture accuracy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture probe for neuronavigation. Background technique [0002] With the popularity of neurosurgery navigation systems, especially in primary hospitals, surgical navigation systems have expanded from early tumor positioning to various neurosurgery operations, especially in puncture catheterization operations because of their precise positioning and visual , are widely used. Due to the lack of a dedicated puncture probe, an adapter and a puncture catheter need to be combined during the puncture operation, and the puncture can only be performed after system adaptation. Multi-tube puncture needs to be adapted one by one, which greatly wastes the operation time and increases the number of repeated adaptations. human error.

AI Technical Summary

Problems solved by technology

However, regarding a specification that can be generally applied to clinical practice, there is no need for re-adaptation during the operation, which simplifies the operation process and saves operation time. It can take into account the puncture depth at all angles of the skull, and avoid puncture caused by too long puncture needle and insufficient hardness. The displacement of the needle end leads to puncture deviation, and there is no relevant report on a puncture probe used for neuronavigation to ensure the accuracy of puncture
