Tumor therapy has entered the minimally invasive therapeutic era mainly with needle penetration. Needle type operations such as needle biopsy, ablation, argon-helium knife, nano knife, particle implantation and the like all need to be accurately punctured into the tumor and then treated. Accurate puncture is the key to needle surgery. Various puncture guide devices are currently available, such as a planar guide template, an adjustable-angle guide template, a 3D printing individualized guide template, and the like. Can partially meet the requirement of puncture guidance, but various templates have respective advantages and disadvantages and cannot be replaced mutually for a while.
The flat template has the advantages of simple application and easy learning, and has the defects that all needle channels are required to be parallel, partial tumors are difficult to puncture in place during multi-needle puncture, and the used needle channels are more.
The angle-adjustable template is greatly improved on the basis of a plane template, the angles among all the needle channels are not required to be parallel, and the single needle channel guide hole can be detached during operation, so that the direction of the needle channel can be conveniently adjusted during the operation. But still limits the adjustment of the needle paths to a certain extent, and the direction of each row of needles must be consistent and can not puncture non-coplanar needle paths.
The 3D printing individualized guide template is designed completely according to the tumor position, the organs at risk and the body surface contour of a patient, each needle channel can be freely designed and is not parallel to each other completely, and not only can puncture a coplanar needle channel but also can puncture a non-coplanar needle channel. Once the procedure is complete, the procedure must be performed as designed, and the intraoperative surgical plan is difficult to adjust. Encountering an emergency may cause the template to be unusable.
At present, no device can simultaneously meet the advantages of the three templates and has no defects.
