Surgical robot and its puncture mechanism

Abstract

The present invention provides a puncture mechanism, which is used to drive a puncture needle assembly to perform an intervention operation, and the puncture mechanism includes: a base; a puncture movement structure slidably arranged on the base; the puncture needle assembly is set On the puncture movement structure, the puncture movement structure drives the puncture needle assembly to slide out or slide in relative to the base; and a limiting structure is slidably arranged on the base, and the limiting structure It can abut against the puncturing movement structure, and is used to limit the movement stroke of the puncturing movement structure. In this way, the length of the puncture needle assembly extending into the focus of the patient can be ensured; the puncture needle assembly can be accurately inserted into the focus of the patient, preventing the puncture needle assembly from passing through the focus or failing to reach the focus, and improving the puncture mechanism for interventional operations Timely security and reduce potential safety hazards. The invention also provides a surgical robot.

Description

technical field [0001] The invention relates to medical puncture equipment, in particular to a surgical robot and a puncture mechanism thereof. Background technique [0002] Puncture biopsy is very common in interventional surgery. Since everyone's body shape and lesion location are almost different, the length of each puncture needle entering the human body will also change accordingly. Usually, the puncture needle will have a circle mark every 10mm on the outer wall of the needle barrel, which is used to help doctors calculate the length of the puncture needle pierced into the human body, so as to judge whether it has reached the target position. Since the markings on the outer ring of the puncture needle are at intervals of 10 mm, the doctor can only read the approximate length when observing with the naked eye, for example, the penetration depth of the puncture needle is between 30 and 40 mm. If a more accurate value is required, it is often necessary to use ultrasound ...

AI Technical Summary

Problems solved by technology

[0003] Based on this, it is necessary to provide a puncture mechanism that can conveniently judge the penetration depth of the puncture needle assembly and ensure safety in view of the safety problems caused by the inability of current medical staff to accurately judge the length of the puncture needle inserted into the lesion of the patient. Provide a kind of surgical robot containing above-mentioned puncture mechanism
