Description

Laser-assisted in-plane guided ultrasonic probe puncture intervention auxiliary instrument Technical Field The invention relates to the technical field of ultrasonic assistance, in particular to an auxiliary instrument for guiding an ultrasonic probe to puncture and intervene in a laser-assisted plane. Background The ultrasonic probe puncture intervention technology is a minimally invasive technology widely applied to modern clinical diagnosis and treatment, and has the core principle that a real-time ultrasonic imaging device is utilized to accurately position an in-vivo target, a real-time sound image is utilized to guide a puncture needle to reach a focus position through skin accurately, so that diagnosis and treatment operations such as tissue biopsy, liquid drainage, drug injection or tube placement are completed, when in puncture, a doctor firstly performs ultrasonic scanning through a handheld probe to determine focus positions, depth and anatomical relations between the focus positions and depth and surrounding important organs and blood vessels, then marks a needle inlet point on a body surface and performs local disinfection and anesthesia, when in formal puncture, the doctor needs to stably hold the probe with one hand to maintain continuous display of an ultrasonic section, and the other hand holds the puncture needle to puncture along a preset path, so that the needle point always remains in an ultrasonic scanning plane and accurately tracks the movement track until the needle point reaches a target area through continuously fine tuning the angle and the needle inlet direction of the probe. In clinical practice, the core limitation of the ultrasonic guided puncture is that the operation precision and the safety of the ultrasonic guided puncture are highly dependent on the personal experience and hand-eye coordination capability of doctors, especially when in-plane puncture, because the ultrasonic scanning is only an extremely thin sector section, an operator needs to maintain the needle body not to deviate from a virtual plane only by echo signals under the condition that the needle body cannot be directly seen, and meanwhile, the operator needs to deal with real-time interference caused by respiration, tissue resistance change and hand vibration of a patient, the operation difficulty is extremely high, surrounding tissues are extremely easy to be accidentally injured once a needle point deviates from an ultrasonic detection range, serious complications are caused, therefore, partial clinical attempts adopt simple auxiliary means, such as temporarily fixing a word line laser on the side of the probe through an adhesive tape, in an attempt to indicate the ultrasonic detection direction by utilizing projection formed by laser on the surface of the needle body, however, because the laser head is only fixed through flexible binding, the angle of the laser head is extremely easy to be changed by external force, the strict coincidence between the laser emission plane and the ultrasonic beam scanning plane is difficult to be ensured, and the operator has deviation between an actual needle insertion path judged by the laser line and an actual imaging plane due to lack of effective calibration mechanism in use. Disclosure of Invention The laser head is fixed only through flexible binding, the angle of the laser head is extremely easy to be changed due to the influence of external force, strict geometric coincidence between a laser emission plane and an ultrasonic beam scanning plane is difficult to ensure, and an effective calibration mechanism is lacking in use, so that an operator judges that deviation exists between a needle inserting path according to a laser line and an actual imaging plane. In order to solve the technical problems, the embodiment of the application provides an in-plane guiding ultrasonic probe puncture intervention auxiliary instrument which comprises a first combination plate, a second combination plate and a laser guide arranged on the first combination plate, wherein the first combination plate is arranged on an ultrasonic probe, a movable block capable of lifting is arranged on the first combination plate, a deflection seat is arranged on the movable block, a deflection shaft connected with the laser guide is rotatably arranged on the deflection seat, combination units are arranged on the first combination plate and the second combination plate and used for detachably arranging the first combination plate, the second combination plate and the laser guide on the ultrasonic probe, a path adjusting unit connected with the movable block and the deflection shaft is arranged on the first combination plate and used for synchronously driving the movable block to lift so as to adjust the height of the laser guide and driving the deflection shaft to deflect so as to adjust the deflection angle of the laser guide according to the insertion depth and angle change of a puncture needle in
