Description
Technical Field
The utility model relates to a minimally invasive surgery technical field especially relates to a built-in pincers suit of arresting of minimally invasive surgery intervention pipe.
Background
Although the iatrogenic foreign body of the great vessels of the heart is rare, in recent years, with the development of interventional diagnosis and treatment technology, the wide application of the drug delivery through a peripheral venous indwelling central catheter (PICC) occurs when various catheters, guide wires and other special instruments are broken in the great vessels. Cracked seal wire and pipe can alternate position and form under the scouring action of complicated heart chamber and great vessel blood flow, can hang on the chordae tendineae, also can twine into a group and block up the blood vessel, and its position form in vivo is different, differs to the severity of organism influence: placement of the catheter in the heart chamber may induce arrhythmias, placement in the pulmonary artery may cause pulmonary embolism, and serious conditions may threaten the life of the patient. The traditional surgical incision for taking foreign bodies in a body, particularly foreign bodies in a heart cavity, is complex in operation process, high in operation risk and multiple in complications, and can not be borne by part of patients. The interventional operation only needs the local anesthesia back venipuncture to insert the operation catheter, so that the wound is small, the operation time is short, the postoperative care is convenient and simple, the compliance of the patient is high, the intraoperative and postoperative complications are slight, the operation success rate is high, the influence on the whole body of the patient is small, and the postoperative recovery of the patient is fast.
The existing commonly used instruments for taking out foreign matters by intervention are goose neck snares, basket snares and the like, and the success rate of the commonly used snares is higher for catheter guide wires floating in large blood vessels and free at one end in a heart cavity. However, for a catheter guide wire with one end embedded in a small blood vessel and the other end attached to the wall or hung on a chordae tendineae, the success rate of the conventional snare is low, and the broken catheter or guide wire is usually pulled out of a heart cavity by means of instruments such as a pigtail catheter and the like, so that one end of the broken catheter or guide wire is dissociated, and then the snare is used for extracting foreign matters. The operation is complicated, the operation time is long, the operation success rate is low, and therefore the built-in capture forceps set for the interventional catheter of the minimally invasive surgery is provided.
