Description
Technical Field
The invention relates to the field of intracardiac surgical instruments, in particular to a intracardiac puncture positioning device.
Background
The cardiology department is a clinical department set by the department of major department of hospitals for diagnosing and treating cardiovascular diseases, and the treated diseases comprise angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beat, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. The puncture is a diagnosis and treatment technology for puncturing a puncture needle into a body cavity to extract secretion for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting medicine into the body cavity.
The conventional puncture operation comprises an anterior approach method, a middle approach method and a posterior approach method.
Front path method: the operator touches the common carotid artery pulse with the index finger and middle finger of the left hand 3cm beside the midline at the front edge of the midpoint of the sternocleidomastoid muscle corresponding to the upper edge of the formative cartilage, pushes the common carotid artery inwards, advances the needle at 0.5cm of the outer edge of the common carotid artery, makes an angle of 30-40 degrees with the skin, and the needle tip advances toward the 1/3 junction in the nipple or collarbone on the same side. Often, the needle is inserted into the internal jugular vein behind the middle section of the sternocleidomastoid muscle, which results in less chance of pneumothorax, but is easily inserted into the common carotid artery by mistake.
The middle road method comprises the following steps: at the apex of the triangle formed by the clavicle and the sternum head of the sternocleidomastoid muscle, the internal jugular vein is just in the center of the triangle, the point is about 3-5 cm away from the upper edge of the clavicle, the stem and the skin form an angle of 30 degrees when the needle is inserted, and the stem and the midline are parallel and direct to the foot end. If the test is unsuccessful, the needle tip is withdrawn subcutaneously and then deflected outwardly by about 10 ° to the trailing edge within the clavicle head of the sternocleidomastoid muscle, often with success.
If the patient is obese, short necked or in children, the marking of the breast lock mastoid muscle after general anesthesia is often unclear, and the positioning has some difficulties. At this time, a small notch at the upper edge of the medial end of the collarbone can be used as a osseous marker (this notch is the attachment point of the sternocleidomastoid bone) through which the internal jugular vein just descends to merge with the subclavian vein. The puncture is performed by pressing the left thumb to confirm the incision, and the needle is inserted about 1-1.5 cm above the incision (the needle insertion is also called as a low-level needle insertion point), the needle stem is parallel to the midline, the needle tip points to the foot end, and the internal jugular vein can be accessed by inserting the needle generally about 2-3 cm. If the needle is not successfully withdrawn subcutaneously, a slightly outward deflection of the needle may often be successful.
Back-pass method: the point of intersection of 1/3 of the middle and lower part of the posterior edge of the sternocleidomastoid muscle or 3-5 cm above the collarbone is used as a needle insertion point, the internal jugular vein is located under the sternocleidomastoid muscle and slightly deviates to the outer side, the face turns to the opposite side as much as possible during puncturing, the needle shaft is generally kept horizontal, and the deep part of the sternocleidomastoid muscle advances towards the fossa sternum. The needle tip should not be too deep inward to damage the common carotid artery or even penetrate into the trachea.
The three needle insertion points are generally more than the middle way, and because the points can directly contact the common carotid artery and avoid the common carotid artery, the chance of accidentally injuring the artery is less. In addition, the internal jugular vein is shallow, and the middle-jiao-meridian rate is high. In addition, it should be noted that, because the internal jugular vein is very close to the common carotid artery, in order to avoid accidentally injuring the artery, a thin needle must be used to try to determine the angle and depth of penetration before formally performing the penetration.
In auxiliary puncture operation equipment of the prior art, the equipment that can nimble adjustment pjncture needle angle lacks, can't audio-visual display angle and degree of depth, consequently in the in-service use, can't play the accurate demand of operation requirement, produces medical accident easily, and lacks the auxiliary assembly of inserting needle among the prior art, and the pressure that the syringe needle received when can't show the needle influences doctor's judgement.
