Description
Technical Field
The invention relates to the field of medical instruments, in particular to a combined type interventional operation guide template which is suitable for various percutaneous interventional minimally invasive operations and used for positioning and guiding surgical instruments.
Background
The interventional operation is one of the common methods for clinical tumor diagnosis and treatment, and the establishment of puncture channel is one very important step in completing the interventional operation. The current guide template mainly has two types, one is a coplanar template, and the other is a non-coplanar template for 3D printing.
The clinical application of coplanar templates has advantages and disadvantages: the coplanar template is formed by punching a plurality of parallel pinholes on a plane, so that puncture needles can be uniformly distributed and kept parallel to each other, which is beneficial to uniform radioactive particle planting, but the problem is that no other organs are shielded around a tumor focus, and the clinical practical situation is that most of the tumor focus and the surrounding organs are shielded mutually, so that the coplanar template has the following defects: the puncture angle on only one plane can be provided, and when bony shielding, important organs and the like are avoided and the tumor focus needs to be punctured from different directions, the coplanar template can not meet the requirement of multi-angle puncture.
The clinical application of 3D printing non-coplanar template has the advantages and disadvantages: although the 3D printing non-coplanar template can provide a plurality of plane angles according to the plan before the operation, theoretically can satisfy the requirement of multi-angle puncture, in the actual operation process, when organs drift due to pneumothorax, intracranial pressure change and the like, the puncture path changes, the 3D printing non-coplanar template manufactured according to the preset puncture angle before the operation cannot be used, and the original plan mode cannot be changed in the operation, so that the plan before the operation fails.
