Surgical system and positioning navigation method

By using a surgical system and positioning navigation method in percutaneous lung puncture biopsy, generating a conversion relationship using a marking unit and an image acquisition unit, and controlling the movement of the surgical unit to the target position, the radiation and risk issues caused by reliance on CT images in existing technologies are resolved, achieving a safer and faster puncture operation.

AI Technical Summary

Technical Problem

The current percutaneous lung puncture biopsy relies on CT images to determine the location of the lesion, which requires doctors to adjust the puncture angle multiple times when they lack experience, increasing the patient's radiation exposure and operation time, and the operation is high-risk.

Method used

A surgical system and a positioning navigation method are used. By setting a first marking unit on the target object, the image acquisition unit and the navigation unit are used to identify the mark, a conversion relationship between the target position and the surgical unit is generated, and the surgical unit is controlled to move to the target position, thereby reducing the number of CT imaging times.

Benefits of technology

It reduces the number of times patients are exposed to CT radiation, shortens the operation time and operation risks, and improves the accuracy and safety of puncture.

Abstract

The present invention relates to a surgical system and positioning navigation method, wherein a surgical unit is capable of moving to a target position of a target object, the target object having a first marking unit, the first marking unit including at least three non-collinear first markings disposed on the target object, the surgical unit having a second marking, an image acquisition unit for acquiring a first transformation relationship of the target position in a coordinate system where the first marking unit is located, a navigation unit for acquiring a second transformation relationship of the second marking in a coordinate system where the first marking unit is located, a control unit connected to the surgical unit, the control unit for generating a third transformation relationship between the target position and the surgical unit based on the first transformation relationship and the second transformation relationship, and controlling the surgical unit to move to the target position based on the third transformation relationship. The first transformation relationship can locate the target position, and acquiring the first transformation relationship only requires a single operation, requiring only one CT scan of the patient, significantly reducing risk.
