Puncturer with defogging tube guide structure

Abstract

The invention aims at providing a puncture outfit with a demisting tube guide structure, and the puncture outfit is capable of effectively improving the neck operation efficiency of an endoscope. The puncture outfit comprises the puncture outfit as a main body and the guide structure, wherein the guide structure is communicated end to end; the head and the tail of the guide structure are flush with those of a puncture sheath of the puncture outfit; the guide structure is attached to the puncture sheath to form a whole body. The puncture outfit has the advantages that (1) a demisting tube can be conveniently arranged in the puncture outfit; (2) a good sealing effect can be achieved; (3) the demisting tube can synchronously move along with the endoscope, so that smoke near the endoscope can be removed in time, the monitoring effect of the endoscope is prevented from being interfered, and the operation time is effectively shortened; (4) the puncture outfit is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a piercer with a defogging pipe guide structure. Background technique [0002] Since the skin in the surgical area of ​​the neck is exposed, the scars of the incisions are often visible after conventional surgery. With the extensive and in-depth development of minimally invasive surgery, many scholars have begun to explore the use of endoscopic techniques for thyroidectomy in recent years, so as to achieve aesthetic and minimally invasive results. For example, when using endoscopic techniques for thyroid surgery, the three-hole method is usually used: the first puncture port is located 0.5 cm to the right and left of the patient's sternal body at the line connecting the two nipples. The endoscope is placed in the center; the other two puncture ports are selected at the upper edge of the patient's double breast areola or near the bilateral armpits. Incorporate minimally invasive instruments and electrocoagulation hemostats (or...

Problems solved by technology

For example, when using endoscopic techniques for thyroid surgery, the three-hole method is usually used: the first puncture port is located 0.5 cm to the right and left of the patient's sternal body at the line connecting the two nipples. The endoscope is placed in the center; the other two puncture ports are selected at the upper edge of the patient's double breast areola or near the bilateral armpits. Incorporate minimally invasive instruments and electrocoagulation hemostats (or ultrasonic scalpels), and electrocoagulation hemostasis is required for electrocoagulation hemostasis during the operation, and a large amount of smoke will be generated during electrocoagulation hemostasis, if the smoke is not removed, it will It interferes with the monitoring effect of the endoscope and affects the progress of the operation. Therefore, during the operation, a demist tube is often placed next to the trocar at the first puncture port

However, once the position of the trocar placed in the endoscope is moved, because the defogging tube cannot move with the movement of the trocar by itself, the defogging tube cannot remove the smoke near the trocar in time, and the smoke will still interfere with the endoscope Therefore, the defogging tube has to be manually moved; in addition, the defogging tube is inserted from the side of the puncture device at the first puncture port, and then the defogging tube and the skin are pasted with adhesive tape, which makes it difficult to When the mist tube is not pasted firmly, the injected carbon dioxide gas will easily escape from the periphery of the demist tube, resulting in air leakage; this not only brings inconvenience to the operation, but also prolongs the operation time; moreover, because human skin tissue It will be inconvenient to insert the defogging tube directly from the first puncture port
