Phantom capable of automatically simulating respiratory cycle and puncture navigation system comprising phantom

Abstract

The invention discloses a phantom capable of automatically simulating a respiratory cycle, which comprises a motor controller and a motor driving device; the motor controller controls the motor driving device to move according to input real person respiratory data; and the motor driving device moves to drive the simulated skin of the phantom to perform fluctuating motion for simulating respiration. The phantom disclosed by the invention can copy and simulate a real respiratory cycle signal, can be used for simulating a pleuroperitoneal cavity puncture navigation experiment in combination with a puncture navigation system, and can solve the problems as follows: in the prior art, the difficulty of accurately controlling air pressure, air flow and inflation and inhalation frequency is relatively large when a human body change condition is simulated by utilizing airbag deformation during simulated respiration; a real respiratory cycle signal is difficult to simulate and match; and an air bag can generate permanent deformation after being used for many times, so that the experiment effect is influenced.

Description

technical field [0001] The invention relates to the medical field, in particular to a phantom for automatically simulating a breathing cycle and a puncture navigation system including the phantom. Background technique [0002] With the development of minimally invasive interventional therapy technology and imaging technology, breathing tracking and compensation become particularly important in the face of percutaneous thoracoabdominal puncture surgery, because the target area of ​​the lesion in the body will produce periodic movement with breathing. Without the assistance of breathing tracking, doctors will face the following difficulties when performing interventional puncture: [0003] (1) The doctor cannot accurately locate the target area of ​​the lesion, mainly relying on personal skills and clinical experience, resulting in prolonged operation time and increased surgical risk; [0004] (2) Considering the safety and accuracy of the operation, the doctor needs to suspe...

AI Technical Summary

Problems solved by technology

[0003] (1) The doctor cannot accurately locate the target area of ​​the lesion, mainly relying on personal skills and clinical experience, resulting in prolonged operation time and increased surgical risk;

[0004] (2) Considering the safety and accuracy of the operation, the doctor needs to suspend the operation process many times to scan the image to confirm and correct the puncture path, which will cause the patient to receive more radiation exposure, which may lead to other hidden dangers during the operation

It is difficult for such schemes to precisely control the air pressure, airflow size, and inhalation frequency, and it is difficult to simulate and match the real breathing cycle signal, and the airbag will produce permanent deformation after repeated use, which will also affect the experimental results;

[0008] Second, most of the phantoms currently used for percutaneous puncture experiments are static models. This type of phantom has the following problems: the epidermis is permanently damaged after several punctures, and it cannot be repaired. The phantom needs to be replaced as a whole, which increases the cost of the experiment
