3D printing personalized plunger type puncture treatment template with fixing device

Abstract

The invention relates to a 3D printing personalized plunger type puncture treatment template with a fixing device. The treatment template comprises a template base plate, template guide holes, puncture needle guide columns, fine adjustment bracket insertion holes, positioning holes, lightweight through holes, laser alignment lines, puncture needle numbers, depth marks and the like. The template puncture needle guide columns can be taken down at any time, the diameter of the template guide holes is large and the length of the template guide holes is small after template puncture needle guide columns are taken down, so that local anesthesia points are accurate in positioning, local anesthesia is easy to implement, a bone drill with a large diameter can be conveniently used, and drilling andpositioning are precise. The three fine adjustment bracket insertion holes are formed and matched with a fine adjustment bracket in use so that the position of the template can be fine adjusted and fixed. The puncture needle numbers and the depth marks are arranged on the surface of the template base plate, and the situation that puncture needles are inserted by mistake because no depth marks arearranged is prevented. The template is customized, each puncture needle is precisely designed before operations according to CT, magnetic resonance and other medical images, precise minimally invasivesurgery is achieved, operation difficulty and operation risks are greatly reduced, the learning cycle of young doctors is shortened, services are quickly conducted, and then more patients are benefited.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a 3D printed personalized plunger puncture treatment template with a fixing device. Background technique [0002] With the advancement of medical technology, precise, minimally invasive, and personalized treatment technologies for tumors have developed rapidly, and minimally invasive treatments such as coaxial biopsy, microwave, radiofrequency ablation, and seed implantation have been widely used in clinics. However, in the past, doctors needed to insert the puncture needle with their bare hands under the guidance of B-ultrasound and CT. The learning cycle was long, the accuracy was poor, and the repeatability was low, and the expected treatment effect was often not achieved. With the continuous application of 3D printing technology in medicine, the emergence of various 3D printed coplanar and non-coplanar puncture guide templates has greatly improved the accuracy of minimal...

Problems solved by technology

[0003] However, the 3D printed coplanar templates have the same puncture needle track angles, which cannot achieve completely personalized and precise treatment; the non-coplanar template needle tracks are individually designed for each patient. Although personalized and precise treatment can be achieved, there are still the following disadvantages :

[0004] (1) The guide column is long and the hole diameter is small. It is often difficult to perform skin anesthesia at the needle point after the template is placed, but it is impossible to determine the needle point after removing the template. Epidural anesthesia instead, increasing patient suffering

[0005] (2) Due to the need of 2-5 days for positioning, design and printing, and the influence of tumor size, location, body position, breathing and other factors, there may often be a certain deviation between intraoperative and preoperative positioning, which does not match the preoperative design of the needle path. If there is no real-time adjustment during the operation, there is a risk of operation failure

[0006] (3) There is no reliable fixing device for the non-coplanar template, and it cannot be fixed after reset, and it is often necessary to hold it by hand, which increases the difficulty of the operation

[0007] (4) Bone drills with a diameter larger than the puncture needle hole cannot be used when the skull and ribs are blocked. When a puncture needle or a small-sized bone drill is used to make a hole, the puncture needle is difficult to pull out, which increases the difficulty of the operation

[0008] (5) There is no depth mark, and multiple people are often required to confirm the depth repeatedly, which increases the operation time
