Auto-synchronous respiratory gating device and control method

Abstract

The invention provides an auto-synchronous respiratory gating device and a control method. The device comprises a gating controller, wherein the gating controller comprises an air pressure detection module, a processor module, a communication module and an indication module; the collection end of the air pressure detection module is arranged at the pressure collection position of a corrugated pipedevice; the output end of the air pressure detection module is connected with the processor module; and the processor module is connected with an external host through the communication module. Compared with the prior art, the device has the advantages that the air pressure value corresponding to respiratory gating is collected through the gating controller and is sent to the external host and isadded with the time-stamp of the external host, and an air pressure value sequence with the time-stamp is formed; when the external host controls a host to prepare for performance of operation planning, and the respiratory gating respiratory amplitude corresponding to the corresponding time-stamp can be known according to the time information in an image file in the current operation planning, sothat a patient can be guided to hold breath, the breath holding state of the patient can be monitored, current respiratory gating position is synchronized with the respiratory position correspondingto the image planning, and puncture can be performed accurately.

Description

Technical field[0001]The present invention relates to the technical field of medical equipment, in particular to an automatically synchronized breathing gate control device and a control method.Background technique[0002]In traditional puncture operations, the process of puncturing the puncture needle to the lesion requires the doctor to rely on the image of the CT / MRI imaging machine and then perform the puncture based on experience. The accuracy depends on the doctor’s experience; with the development of technology, the use of respiratory gating has begun to appear. For assisted puncture technology, the existing respiratory gating device for interventional surgery requires the doctor to manually perform baseline recording. During CT / MRI scans, the patient is required to hold his breath, and the indicator light on the respiratory gate to record the position of the patient’s breathing during the scan is recorded. Then the human eyes judge whether the breathing position indicated by t...

Problems solved by technology

This method is also greatly influenced by the operator's subjective

In addition, if the patient's breath-hold position is not fixed during the operation, the baseline position will drift, resulting in low accuracy and affecting the therapeutic effect of puncture surgery
