Portable puncture outfit and puncture device and method composed of same

Abstract

The invention discloses a portable puncture outfit. The portable puncture outfit comprises a target, a working sheath, a puncture needle and a handle; the working sheath is of a hollow structure; thepuncture needle comprises a needle base, a needle tube, a lining core and a limiting block; one end of the lining core is fixedly connected with the bottom end of the limiting block, and the other endof the lining core is embedded into the working sheath and is in threaded connection with the working sheath; the top end of the limiting block is detachably connected with the needle base; the top end of the needle tube is fixedly connected with the needle base, and the bottom end of the needle tube penetrates through the limiting block, the lining core and the working sheath and extends out ofthe working sheath; the lining core rotates along the inner wall of the working sheath in a threaded mode and can limit the length of the portion, extending out of the outer end of the working sheath,of the needle tube; the handle is fixed under the working sheath; and the target is fixed right above the working sheath. The puncture needle is convenient to disinfect and clean, puncture deviationor slipping is prevented, and the accuracy and safety of a puncture operation can be effectively improved.

Description

technical field [0001] The invention relates to the field of puncture surgery, in particular to a portable puncture device and a puncture device and method thereof. Background technique [0002] When performing minimally invasive spinal percutaneous puncture, it is necessary to perform accurate puncture with the assistance of X-rays. At present, surgeons mostly use preoperative data obtained through MRI, CT machines, X-ray machines and other imaging equipment combined with anatomical and pathological knowledge to plan surgery, and combine real-time images obtained by X-ray machines during surgery to roughly determine the needle insertion point and puncture direction. In the actual puncture process, in order to ensure accurate avoidance of damage to important soft tissues, it is usually necessary to perform multiple X-ray irradiations on the human body, which will not only increase the operation time, but also greatly increase the number of radiation exposures of doctors and...

Problems solved by technology

In the actual puncture process, in order to ensure accurate avoidance of damage to important soft tissues, it is usually necessary to perform multiple X-ray irradiations on the human body, which not only increases the operation time, but also greatly increases the number of radiation exposures of doctors and patients

[0003] In addition, during the puncture process, the doctor is affected by personal experience and operating habits, and is limited by the error of human beings' sense of direction in three-dimensional space, resulting in poor puncture accuracy. Even through practice, it is difficult to achieve the desired effect with one needle insertion. , it is necessary to repeatedly try, adjust the angle and depth to approach the puncture target, which will not only easily cause unnecessary tissue damage, but even cause serious complications leading to puncture failure
