Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of self-locking type hepatic portal blocking belt.
Background technique
Liver blood supply is very big, and the blood volume of liver is equivalent to the 14% of human body total amount, adult liver, per minute
Blood flow has 1500~2000ml.The blood vessel of liver is divided into liver blood vessel and out two groups of liver blood vessel.Entering liver blood vessel includes that liver is inherently dynamic
Arteries and veins and portal vein belong to dual vascularity.Liver blood vessel is vena hepatica system out.Arteria hepatica is the nutrient vessel of liver, liver blood supply 1/4
From arteria hepatica enter liver after be divided into it is at different levels be branched off into interlobular artery, will directly from the arterial blood of heart input liver,
Mainly for oxygen.Portal vein is the function blood vessel of liver；From portal vein, portal vein divides after entering liver for the 3/4 of liver blood confession
It is branched off into interlobular veins to be at different levels, is sent nutritious blood is contained from alimentary canal to liver " processing ".
Since hepatic blood supply is abundant, in operation on liver, for reduce liver during surgery big bleeding the case where, usually
It needs to block into hepatic blood flow；Complete in-degree sequence is classical Pringle method, block completely porta hepatis arteria hepatica and
Portal venous flow.This method is most widely used.Common way is: with No. 13 catheters or thin adhesive tape around the finger of liver 12
Intestines ligament tightens catheter or adhesive tape with vessel forceps, but the most common mistake of the method is: usually having takeed for vessel forceps
Vessel forceps slip when tightening adhesive tape or blocking, and operative doctor is not known, causes barrier effect unobvious, is cut liver and is appointed so to go out on the way
Blood is more.
Utility model content
The purpose of this utility model solves problems of the prior art, and providing one kind can simply and easily be applied to
The self-locking type hepatic portal blocking belt of porta hepatis blood flow is blocked in operation on liver.
To achieve the goals above, the utility model provides a kind of self-locking type hepatic portal blocking belt, comprising: blocks stick, resistance
Disconnected band, multiple double wedges and tooth socket；The blocking stick is equipped with one and blocks belt insertion slot, for being inserted into the blocking band；The tooth socket
It is penetrated through on the blocking stick, and with the blocking belt insertion slot, the tooth socket is adapted to the double wedge shape size；It is described
One end of band is blocked to be fixedly connected with the blocking stick；The other end for blocking band is movable end, and can be inserted into the blocking
Belt insertion slot；The outside of the blocking with movable end is uniformly fixed with the multiple double wedge, and the blocking band movable end passes through
The connection of the adaptation of the double wedge and tooth socket is adjustable to be fixed on the blocking stick.
Further, self-locking type hepatic portal blocking belt as the aforementioned, the blocking stick include: soft silica gel section, adjust section and bullet
Property middle layer；The soft silica gel section is fixedly connected with the adjusting section, and is set to the arrival end for blocking belt insertion slot；The tune

The cost that device can thus be reduced on the whole, is easy to the popularization and use of device.
Further, self-locking type hepatic portal blocking belt as the aforementioned, it is described to block with the blocking including being mutually permanently connected
Band outer layer and blocking band internal layer；The blocking band outer layer is plastic layer；The blocking band internal layer is soft silica gel layer.Outer layer is using modeling
The bed of material can preferably prevent from blocking with deformation；Internal layer can to reduce pressure during operation using soft silica gel layer
Compel the blood vessel and bile duct in hepatic portal, reduces and damaged caused by compressing hepatic portal.
Further, self-locking type hepatic portal blocking belt as the aforementioned, the top of the blocking with movable end are wedge shape.Thus
Easily band insertion will can be blocked to block in belt insertion slot.
In the above-mentioned technical solutions, the self-locking type hepatic portal blocking belt of the utility model can quickly form closed loop, and Bao Rao exists
The outside of hepatic portal realizes vascular flow in compressing hepatic portal, liver is made to be in short time ischemic state, reduces operation and cuts going out for liver
Blood, while only needing to press at pressing at the end of operation is fast, can loosen hepatic portal；In addition, blocking band inside and blocking stick one
Side is soft silica gel, can reduce the damage after blocking to hepatic portal blood vessel, and easy to operate, shortens operating time.
