Two-dimensional angle digital display needle and method for display angle by utilizing same

Abstract

The invention relates to a two-dimensional angle digital display needle. The two-dimensional angle digital display needle comprises an angle display device and a needle body; the angle display device is fixedly connected with the needle body; the angle display device comprises an angle sensing element, a display screen, a microprocessor and a power supply module; the angle sensing element is arranged on the needle body; the angle sensing element, the display screen and the microprocessor are respectively electrically connected with the power supply module; the microprocessor is respectively electrically connected with the angle sensing element and the display screen. By adopting the design, the two-dimensional angle data in the transverse direction and longitudinal direction can be simultaneously measured and displayed, the angle control can be carried out by a doctor in real time when the puncture operation under the guide of CT or MR is carried out, so that a focus can be accurately punctured according to a predetermination direction, the ablation or biopsy operation can be carried out, the workload can be alleviated, the adjusting time is saved, and the complication can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical electronic equipment, in particular to a method for monitoring a two-dimensional digital display ablation needle and its display angle. Background technique [0002] At present, clinical CT or MRI-guided ablation surgery relies too much on the operator's experience in puncture. Most clinical CT or MR-guided ablation surgery requires preoperative reading of CT or MR images, and first measures the direction and angle of the needle on the computer. Then the operator penetrates the ablation needle into the lesion according to the set angle for tumor ablation. There are many problems in use. For example, after the operator determines the angle on the computer, he can only enter the machine room for puncture according to memory and experience. As a result, there is often a certain error between the puncture angle and the pre-conceived angle, and repeated adjustments are required. In addition, some larg...

There are many problems in use. For example, after the operator determines the angle on the computer, he can only enter the machine room for puncture according to his memory and experience. As a result, the puncture angle often has a certain error from the pre-conceived angle, and repeated adjustments are required. In addition, some large-scale hospitals use 3D simulation imaging technology to solve the above problems, but the high cost is not conducive to widespread promotion
