Embodiment 1

[0023] Such as figure 1 , 2 , 3, the puncture guide template includes a guide template body 1, the guide template body 1 is an irregularly shaped plate-like structure in this embodiment, the guide template body 1 can have a 3D printer using transparent or translucent medical polymers The material is printed, and the thickness of the guide template body 1 is 1-5mm. The specific thickness of the guide template body 1 can be determined according to the experimental results. The guide template body 1 is provided with at least one puncture hole group, and each puncture hole group includes three puncture holes 2 that run through the guide template body 1. Of course, the number of puncture holes 2 in each puncture hole group can also be four or five. One or more, in order to make the puncture needles passing through the same group of puncture holes 2 parallel to each other and at equal distances, the three puncture holes 2 in the same puncture hole group are parallel to each other a...

Embodiment 2

[0031] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the guide template body 1 in this embodiment matches the curve of the body surface of the treatment site, by printing the guide template body 1 to match the curve of the body surface of the treatment site The matching shape can better control the position and angle of the puncture needle inserted into the tumor lesion, and improve the treatment effect.

Abstract

The invention relates to a puncture guide template. The puncture guide template comprises a guide template body, at least one puncture hole group is formed in the guide template body, each puncture hole group comprises at least three puncture holes running through the guide template body, and the puncture holes in the same puncture hole group are mutually parallel and are distributed on the same straight line at equal intervals. A hollow-out window is arranged in the area, where no puncture holes are formed, of the guide template body, and the positions of the puncture holes correspond to thepositions of preset puncture holes of a to-be-punctured tumor one by one. According to the puncture guide template, a puncture needle is fixed and guided through the puncture holes so that the puncture needle can be inserted into the tumor lesion location according to a preset, and depth to treat the tumor lesion location. The puncture guide template has the advantages that the structure is simple, the template is suitable for various different tumors, and the insertion angle and depth of the puncture needle into the tumor lesion location can be accurately and controlled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture guiding template. Background technique [0002] Cancer is one of the major diseases that threaten human health and life. According to a data released by the World Union Against Cancer (UICC), in 2008, there were 12.7 million cancer patients worldwide, of which 7.6 million died. According to the survey and statistics report of the Ministry of Health of China, in the past 30 years, cancer mortality has increased by more than 80%. At present, cancer has become an important disease and the number one killer of health that causes the death of urban and rural residents. The report of the World Health Organization (WHO) also pointed out that on a global scale, new cancer cases and cancer patient death rates will also increase at a rate of 1% per year, while the increasing rate in developing countries such as China, Russia, and India It will be faster. It is estimated...
