Fixtures for 3D printed templates for puncture

Abstract

The invention relates to a medical device, in particular to a fixing device for a 3D printing template for puncturing. The fixing device comprises a three-axis rectangular coordinate system navigation support and a middle connecting piece, wherein the upper end of the middle connecting piece is connected with the three-axis rectangular coordinate system navigation support, and the lower end of the middle connecting piece is connected with the 3D printing template. The 3D printing template is fixed by the three-axis rectangular coordinate system navigation support and the angle of the 3D printing template is spacially regulated, so that the 3D printing template can be stably and accurately reset on the body surface of a patient and thus the tumor target section is precisely reset; the 3D printing template is stably fixed on the body surface of the patient in the whole puncture surgery process and thus the problem that the tumor target section cannot be precisely reset by the result of human factors and surgical factors is effectively solved.

Description

technical field [0001] The invention relates to a medical device, in particular to a fixing device for a 3D printing template for puncture. Background technique [0002] With the rise of 3D printing technology in recent years, coplanar, non-coplanar, and different needle insertion angle puncture templates made by 3D printing technology for various parts of the body are gradually used in clinical practice, but the current 3D printed puncture templates The reset of the 3D printed puncture template can only be achieved by the operator's assistant holding it by hand or fixing it partially with glue. In this way, the reset accuracy of the 3D printed puncture template is easily affected by human factors and surgical factors, resulting in the loss of the target area of ​​the 3D printed template. The accuracy of reduction is poor, which leads to poor treatment effect, and the actual operation during the operation cannot perfectly restore the preoperative plan. Contents of the inve...
