Abstract
The utility model provides a porta hepatis blood blocking device, the blocking area is furnished with a sleeve pipe and elasticity card. When the blocking belt is used, the hepatic portal blood vessel and part of tissues are surrounded by the blocking belt, the two ends of the blocking belt are sleeved by the sleeves, the blocking belt is tensioned, the hepatic portal blood vessel and part of tissues are blocked or partially blocked by pushing the sleeves, and the hepatic portal blood vessel and part of tissues are clamped by the elastic clamp, so that the effect of blocking blood in the hepatectomy operation can be achieved.
Description
Technical Field
The utility model relates to a medical instrument, specific porta hepatis blood blocking device that says so.
Background
When a patient is subjected to laparoscopic hepatectomy, the blood flow of the porta hepatis needs to be blocked by a hospital, so that the flow of the hepatic blood entering the patient is controlled, due to the lack of special blocking instruments, the blocking methods adopted by hospitals in various regions are different, many methods are rough, time-consuming and poor in effect, the difficulty in placement, blocking and relaxation is difficult, creation is increased, and the effect of blocking the hepatic blood flow is poor.
Disclosure of Invention
The technical purpose of the utility model is to solve the above-mentioned problem that exists, provide a porta hepatis blood blocking device, it is very convenient to use, and it is effectual to block blood volume.
The utility model discloses a stop band and sleeve pipe and elasticity card, the technical scheme who adopts lies in: the porta hepatis blood blocking device is composed of a blocking belt and a sleeve with an elastic clamp at the tail end.
In the above technical scheme: the elastic card is characterized in that an opening is reserved on one side of the elastic card, one end of the elastic card is connected with an integrated sealing tongue, the other end of the elastic card is connected with an integrated sealing groove, a sealing plug integrated with the elastic card is arranged below the sealing tongue, and sawtooth cards capable of being clamped mutually are respectively arranged on the inner side of the sealing groove and the outer side of the sealing plug.
The length of the blocking belt is 60cm, the diameter of the middle end is 2mm, and the diameters of the two ends are less than 2 mm.
The length of the sleeve is 20cm, the diameter of the lumen of the sleeve is 6mm, and the thickness of the wall of the sleeve is 2 mm.
The utility model has the following advantages and effects: according to the technical scheme, the blocking belt is matched with the sleeve and the elastic clamp to interact, when the hepatic portal blood vessel blocking device is used, the blocking belt is firstly used for surrounding the hepatic portal blood vessel and part of tissues, the sleeve is sleeved at two ends of the blocking belt, the blocking belt is tensioned, the hepatic portal blood vessel and part of tissues are blocked or partially blocked by pushing the sleeve, and then the hepatic portal blood vessel and part of tissues are clamped by the elastic clamp.
