Embodiment 1

[0041] A method for making a non-coplanar puncture template based on bony multi-point positioning, comprising the following steps:

[0042] Step STP100 Obtain a CT tomographic image Pic covering all target areas, the CT tomographic image Pic includes pre-set marker point imaging in the target area, including four positioning marker points set in the bony area and a The puncture markers set in the puncture area; the four markers set at the bony points are CT scans respectively set at the location of the anterior superior iliac spine on both sides of the hipbone and the location of the greater tuberosity of the humerus on both sides. Image markers. In actual operation, it can be performed during a normal CT examination of the patient, and the tomographic image Pic of the CT examination can be used as the basis for the follow-up of this step.

[0043] Of course, in order to better locate the bony parts, without the need for the doctor to search for the above four bony regions, f...

Embodiment 2

[0056] This embodiment provides a non-coplanar puncture template, which is specifically prepared by the non-coplanar puncture template manufacturing method based on bony multi-point positioning described in Example 1, such as Figure 3-6 As shown, it specifically includes a puncture template body 1, and the puncture template body 1 is also fixedly connected with a plurality of positioning templates extending outward along the periphery of the puncture template body 1 to form a surface fit with the bony parts of the human body. The specific shape of the positioning template can be set according to the actual puncture site. The principle of setting is to collect the bony point positioning points in the axial direction of the human spine, and the thinner the soft tissue coverage is, the better. There are differences depending on the specific puncture site.

[0057] In this embodiment, the puncture site is the chest and abdomen as an example, and the positioning template includes ...

Embodiment 3

[0074] On the basis of Embodiment 1, in order to take into account the production and processing of the preoperative puncture template body 1, and at the same time satisfy the unaffected puncture operation during the operation and provide excellent opening performance, this embodiment further combines the attached Figure 3-Figure 7 As shown, the puncture template body 1 and any one of the positioning templates are fixedly connected by a positioning rod 6, and the positioning rod 6 is composed of a horizontal section 61 arranged horizontally, which is respectively connected to the puncture template body 1 and any one of the positioning templates. The upper surface of the positioning formwork is fixedly connected to form the second vertical section 63 and the first vertical section 62 .

[0075] In order to further quickly locate, to adjust the patient's position during the operation to be consistent with the position during tumor sampling, and realize the rapid positioning of t...

Abstract

The invention discloses a non-coplanar puncture template manufacturing method based on osseous multi-point positioning, which comprises the following steps: acquiring a CT (Computed Tomography) scanning image Pic covering all target areas, performing three-dimensional modeling according to the CT scanning image Pic to obtain a three-dimensional model comprising human skin data and tumor data, taking the length direction of a CT bed as an X axis, the width direction as an Y axis and the normal direction of the CT bed as a Z axis to establish a space coordinate system, taking the mark point with the minimum Z-axis value as the original point of the space coordinate system, and performing expansion processing on any skin data Wn along the Z-axis direction to obtain a plurality of template model data Qn; importing a needle passage plan, exporting puncture template model data K1 and inputting into 3D printing equipment for printing to obtain the non-coplanar puncture template. The puncture template manufactured by the method provided by the invention solves the puncture error caused by the fact that the body position of a patient during tumor sampling before template manufacturing does not correspond to the body position during puncture.

Description

technical field [0001] The present invention relates to the technical field of surgical auxiliary instruments and their manufacturing methods, in particular to the technical field of auxiliary templates for precise puncture and their manufacturing methods, and in particular to a non-coplanar puncture template manufacturing method and template based on bony multi-point positioning . Background technique [0002] Tumor is a major problem faced by medical technology worldwide today. According to the International Agency for Research on Cancer (IARC), in recent years, there are nearly 20 million new cancer patients in the world every year, and nearly 10 million people die because of tumors. Although there are many effective treatment methods for tumors in the existing medical technology, due to the early onset of tumors, there are often no symptoms, which makes early detection and early treatment difficult. Therefore, for example, the method of achieving recovery through surgica...
