A laparoscopic varicocele ligation and puncture device

Abstract

The invention discloses a laparoscopic varicocele ligation puncture device. Such structure design that a fixing mechanism and an anti-disengagement mechanism is adopted, the expansion stretch-out and draw-back principle of an elastic air bag and the adsorption principle of a carbon nano tube array are made use of, a conical head can be effectively prevented from being disengaged from a puncture part, a main sheath tube thus does not move in the human body or outside the human body in the operation process, the operability is largely improved, meanwhile an air guide hole is formed in the conical head, the air inflation effect of a veress needle can be achieved, and the safe use function requirements of puncture and pneumoperitoneum are met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a laparoscopic varicocele ligation and puncture device. Background technique [0002] Varicocele refers to the swelling of the veins in the male scrotum, manifested as swelling and discomfort of the scrotum, pain in the testicles or lower abdomen, aggravated by standing or exertion, relieved when lying down or resting, swollen and drooping scrotum when standing, and loose skin , Visible venous plexus expansion, bending, elongation. Earthworm-like varicose veins can be palpated during palpation, and the varicose veins shrink or disappear after lying down. It is an andrological disease of unknown cause. Any man may suffer from it. Severe cases can lead to testicular atrophy and infertility. question. It is characterized by varying degrees of expansion and tortuosity of the varicose vein plexus in the spermatic cord. According to the etiology, it can be divided into prima...

Problems solved by technology

It consists of a casing sheath with a handle at the tail and a core rod with a core rod seat at the tail. The core rod is a hollow tube with a pinhole at the front end. Veress needle and airway with reset device, the needle of the Veress needle extends out of the core rod from the pinhole, the airway is sleeved outside the end of the Veress needle, and one end of the reset device is connected to the airway and fixed on the On the inner wall of the sheath, the other end of the reset device is fixed on the Veress needle; when the sheath with handle is combined with the mandrel with the mandrel seat and the front end of the mandrel fully extends out of the sheath, it is located in the rubber unidirectional Ventilation holes are provided on the side wall of the core rod below the valve, and the upper opening of the airway is not bordered on the inner wall of the core rod seat. The present invention has the advantages of simple operation and reduced surgical risk; however, the spiral puncture with pneumoperitoneum device Existence of the trocar and its use method: the set positioning ring can only simply prevent the trocar from being inserted into the deep abdominal cavity, and cannot be reliably fixed or positioned, that is, the device is prone to horizontal or axial displacement during the operation , thereby increasing the difficulty of the operation; at the same time, when the axial displacement occurs, the needle tip will fall off from the puncture part. In order to avoid such a situation, the surgeon must perform the puncture very carefully, so the workability is extremely poor and the operation requirements are relatively high. high
