Omnibearing puncture mechanism and medical precise puncture system

Abstract

The invention discloses an omnibearing puncture mechanism and a medical precise puncture system. The omnibearing puncture mechanism comprises an omnibearing rotation mechanism and a puncture device, and the omnibearing rotation mechanism is used for driving the puncture device to rotate by a set angle around a fixed point in three-dimensional space, wherein the fixed point is arranged on the extension line where the puncture direction of the puncture device 30 is located, and the set angle is an arbitrary value between 0 degree and 360 degrees. The puncture device can carry out puncture at anarbitrary angle, and is better kept away from important organs, tissue and the like, and safety of patients is guaranteed.

Description

technical field [0001] The invention relates to a medical device, in particular to an omnidirectional puncture mechanism and a medical precision puncture system. Background technique [0002] Puncture is the process of inserting a puncture needle into the human body to extract secretions and / or soft tissues for laboratory tests, injecting gas or contrast agent into the human body for contrast examination, and placing drugs, positioning markers, and radiated particles into the human body. At least one diagnostic and therapeutic technique for treatment. Since this puncture is carried out on a living body, in order to avoid puncturing into normal tissues by mistake during the puncture process and causing secondary damage to the living body, it is necessary to ensure the accuracy of the puncture. In the past, puncture operations often required the support of X-ray images to achieve precise puncture, which would cause certain radiation damage to medical staff who performed punct...

Problems solved by technology

[0003] However, since the adjustment of the puncture angle of the puncture needle of this puncture needle positioning device needs to adjust the positional relationship to adjust the needle entry angle, that is, the relationship between the distance between the second needle piercer and the first needle piercer and the needle entry angle needs to be adjusted. For conversion, the operation is still relatively complicated; and when the position of the second needle needle is adjusted through the angle adjustment structure, the first needle needle remains stationary. At this time, under the adjustment of the angle adjustment structure, the second needle needle can only Moving along the first direction and / or the second direction can only adjust the needle entry angle of the puncture needle between 0-180° in space, and the needle entry angle of the puncture needle is limited, so it cannot be well avoided when puncturing. defects in organs and tissues

Moreover, these defects also make the use of the puncture needle positioning device limited, and the safety of the patient during puncture cannot be guaranteed.
