CT coplanar puncture template provided with identifier guiding devices and making method of CT coplanar puncture template

Abstract

The invention relates to a CT coplanar puncture template provided with identifier guiding devices. The CT coplanar puncture template comprises a plate body, puncture needle holes, marking lines and lead wires, wherein the puncture needle holes are uniformly distributed in the plate body in rows and columns; the marking lines are arranged on the portions, positioned between any two rows of puncture needle holes and positioned between any two lines of puncture needle holes, of the surface of the plate body; the lead wires are embedded in portions, right below the marking lines, of the plate body; and the lead wires are consistent with the marking lines in length and are parallel with the marking lines. According to the coplanar puncture template provided with the identifier guiding devices, puncture directions of puncture needles can be precisely guided, the template can be placed in accordance with the position and size of a focus before an operation so as to avoid dangerous organs around the focus, the puncture needles can be precisely inserted, and by virtue of the template, the various puncture needles can be kept under a parallel state. The CT coplanar puncture template can shorten an operation time, reduce operation risks and reduce operation difficulty. The template is provided with the guiding lead wires as the puncture needle guiding devices, so that a doctor can intuitively predict moving trends of the puncture needles before inserting the puncture needles, and therefore CT scanning times and puncture difficulty are further reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a CT coplanar puncture template with an identification guide device. Background technique [0002] Tumor is a disease that seriously endangers human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. Whether it is pathological diagnosis or minimally invasive treatment (such as: radioactive seed implantation, radiofrequency, microwave ablation treatment), it is inseparable from extracorporeal puncture, and extracorporeal puncture is an important way to obtain pathological and minimally invasive treatments. [0003] The technique of freehand puncture is difficult and the learning period is long. Therefore, most doctors rely on puncture templates to achieve more precise positioning. Existing puncture te...

AI Technical Summary

Problems solved by technology

The existing puncture template does not have a marking line that can be developed on CT, so the pinholes of the template cannot be quickly matched with the CT image, and the puncture needle needs to be inserted and verified repeatedly to determine the pinhole to be punctured, and multiple CT scans are required at the same time

Secondly, an additional fence-type locator needs to be installed during positioning, which is cumbersome and time-consuming to use

Thirdly, the existing template cannot predict the direction of the puncture needle, and it usually requires repeated puncture to position the puncture needle, which increases the pain of the patient and the number of CT scans, and increases the risk of surgery
