Embodiment 1

[0024] Please see attached figure 1 , figure 1 It is a three-dimensional structure schematic diagram of a puncture probe used for neuronavigation of the present invention. A puncture probe for neuronavigation, the puncture probe for neuronavigation includes an adapter 1 and a puncture needle 2; the adapter 1 includes a positioning body 11 and a fixing part 12; the fixing part 12 Located at the bottom of the positioning body 11; the positioning body 11 is a triangular bracket structure, and the three end surfaces are respectively connected with navigation reflective balls 13 through threaded rotation; the length of the puncture needle 2 is 17-22mm; The end of the puncture needle 2 is fixed inside the fixing part 12 .

[0025] It should be noted that: the puncture probe of the present invention is formed by fusion of the adapter 1 and the puncture needle 2; the positioning body 11 is a triangular bracket structure, and the surface of the end point is connected with a navigatio...

Embodiment 2

[0027] Please see attached figure 2 , figure 2 It is a schematic diagram of the three-dimensional structure of another puncture probe used for neuronavigation of the present invention. This embodiment is basically the same as Embodiment 1, the difference is that the surface of the needle body of the puncture needle 2 in this embodiment is provided with a scale line 21; It is convenient to accurately judge the needle insertion depth of the puncture needle during the puncture process, so as to ensure the accurate puncture position.

[0028] A puncture probe used for neuronavigation of the present invention, the design of the puncture needle length is 17-22mm is based on the inventor's long-term clinical work experience, and it is a specification that can be generally applied to clinical practice, that is, it can take into account the skull The puncture depth at each angle avoids the puncture offset caused by the displacement of the end of the puncture needle caused by too lo...

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. [0003] Chinese patent document: CN201811303773.1, application date 2018.11.03, patent name: A hematoma puncture needle for human neuronavigatio...
