Puncturing and positioning device

Abstract

The invention discloses a puncturing and positioning device which comprises a bed plate, a puncturing template bracket arranged on the bed plate and a puncturing template arranged on the puncturing template bracket, wherein the puncturing template bracket comprises an upper bracket on the upper part and a base on the lower part; the upper bracket can move up and down relative to the base and be locked to regulate the height of the puncturing template; the base of the puncturing template bracket can slide along the length direction of the bed plate and be locked; and the puncturing template can slide and rotate along the upper bracket in the width direction of the bed plate. In a puncturing operation, through the guide of CT (Computed Tomography), puncturing and positioning can be exactly realized through adjusting the position and the angle of the puncturing template and guaranteed to be accurate, and the puncturing operation is convenient. The puncturing template can also guarantee that puncturing implants are uniformly distributed as required, and moreover, the puncturing and positioning device can realize multi-point puncturing, save the operation time and has high puncturing efficiency.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a puncture positioning device for clinical percutaneous puncture operations. Background technique [0002] At present, the method of percutaneous puncture is often used clinically to diagnose and treat diseases. The outstanding advantage of this method is that it is minimally invasive. Whether it is diagnosis or treatment, patients recover quickly after surgery, so it is more and more used. to the clinic. [0003] A large number of clinical data show that 70-80% of cancer patients are already in the middle and advanced stages when they are diagnosed. Traditional tumor treatment methods, such as radiotherapy and chemotherapy, are limited by dose and other factors, and it is difficult to completely inactivate tumor cells, and the therapeutic effect is not good. ideal. Tumor interventional therapy has the advantages of minimally invasive, low cost, safety, and good curative effect. ...

AI Technical Summary

Problems solved by technology

[0007] In view of the above problems, some solutions have been proposed in the prior art. Now there are also some puncture positioners, puncture racks, navigation robots, etc., which have improved the accuracy of puncture to a certain extent, but there are still some shortcomings: after image scanning and positioning, Only single-point puncture can be achieved. When magnetic thermal seeds or radioactive particles need to be implanted in different positions of the tumor, multiple scans and multiple positioning are required. The puncture process is cumbersome and the puncture position is not accurate enough. The uniform distribution of radioactive particles affects the therapeutic effect of tumors

At the same time, due to the long time consumption, the number of patients treated per unit time has been greatly reduced
