Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of gasbag-type blocking band.
Background technique
With the development of minimally invasive endoscopic technic, more and more open surgeries can be operated by laparoscopic surgery,
Implement with succeeding under laparoscope including the more complex operation of the series such as hepatectomy, the nephrectomy, pneumonectomy, these complexity
Laparoscopic surgery is higher for the control requirement of amount of bleeding, therefore blood vessel blocking also becomes an important technology under laparoscope
Component part.The Basilar artery of blood vessel is widely used in various surgical operations, such as hepatotomy, and kidney excision etc. is common
Operation, blood vessel blocking can reduce amount of bleeding when organ removal, while the blocking of vessel branch may determine that organ removal
Edge.
Currently, patient often uses not damaged vascular occlusion clamp clamp artery or quiet in provisional blocking organ blood supply
The vascular wall of arteries and veins and achieve the purpose that blocking blood flow, the tissue for be easy to causeing vessel outer wall to damage in this way and aggravating near vessels is viscous
Even, blood vessel damage causes thrombosis and thrombosis, and this method is not easy to implement under laparoscope.Therefore,
It is necessary to develop a kind of gasbag-type blocking band, to solve the above problems.
Utility model content
The purpose of this utility model is that: in view of the above problems, provide a kind of gasbag-type blocking band, operation letter
It is single, to blood vessel hurtless measure, and it can be rapidly achieved the purpose of blocking blood flow, save inflationtime, improve work efficiency.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of gasbag-type blocking band, one end of the air bag including a strip, the air bag connect flexible blocking ring, institute
The other end for stating air bag, which can bypass, is then passed through the elastic blocking ring after blood vessel, to cover on the blood vessel, the air bag it is tight
The one side for pasting blood vessel is equipped with elastic layer, and the one side of the separate blood vessel of the air bag is equipped with the confining layers for preventing expansion；The air bag
Outer wall be additionally provided with a groove, the elasticity blocking ring is snapped on the groove, the inner plenum and gas tube of the air bag
Road connection.
Further, 2nd/1st to seven/7th of the thickness with a thickness of the air bag of the confining layers.
Further, the material of the confining layers is hard material.
Further, the material of the elastic layer is medical grade rubber or elastic non-woven cloth.
Further, the thickness of the elastic layer is slightly larger than the thickness of the confining layers.
Further, one end concavity of the air bag close to the elastic blocking ring.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. the utility model is easy to operate and to blood vessel hurtless measure, blocked by the way that elasticity is arranged in one end of strip air bag
The outer wall of ring, air bag is equipped with groove, and the other end of air bag is then passed through elastic blocking ring around blood vessel, buckles elastic blocking ring
On groove；Since the one side that air bag is close to blood vessel is equipped with elastic layer, the one side far from blood vessel is equipped with the limit for preventing expansion
Given layer, when inflating to air bag, elastic layer can make air bag expansion not damage blood vessel, while can effectively block blood vessel, be more convenient
Operative doctor is performed the operation；Confining layers can prevent air bag towards expansion outside blood vessel, make only to need a small amount of gas that can make gas when inflation
Capsule is expanded toward vessel directions, and then is rapidly achieved the purpose of blocking blood flow, and this saves inflationtimes, improve work efficiency.
2. the utility model can block vascular flow by inflating air bag, deflates and restore vascular flow, i.e., by simple
The quick inflatable and deflatable blocking repeatedly and release that vascular flow can be realized, it is easy to operate, conducive to the progress of operation.
Detailed description of the invention
Fig. 1 is that a kind of gasbag-type of the utility model blocks band to cover the structural schematic diagram on blood vessel.
In figure: 1- air bag；2- elasticity blocking ring；3- loading line；4- blood vessel.

Embodiment
Such as Fig. 1, a kind of gasbag-type blocking band, one end of the air bag 1 including a strip, air bag 1 connects flexible blocking
Ring 2, the other end of air bag 1 is then passed through elastic blocking ring 2 after can bypass blood vessel 4, to cover on blood vessel 4.The abutting blood vessel of air bag 1
One side be equipped with elastic layer (not shown) so that when operation 1 inner wall of air bag to 4 hurtless measure of blood vessel, the separate blood vessel 4 of air bag 1
It is equipped with the confining layers (not shown) for preventing expansion on one side.The outer wall of air bag 1 is additionally provided with a groove (not shown), elastic blocking ring 2
It is snapped on the groove, the inner plenum of air bag 1 is connected to loading line 3.
The thickness of confining layers can be 2nd/1st to seven/7th of the thickness of air bag 1.The material of confining layers is using hard
Material, to play the purpose of a surface expansion of the separate blood vessel 4 for preventing air bag 1.In the present embodiment, the thickness of confining layers is preferred
It is 1/7th of the thickness of air bag 1, while playing a surface expansion of the separate blood vessel 4 for preventing air bag 1, can also prevents from limiting
Given layer is blocked up and increases the volume of the utility model, and the utility model is caused to be difficult in laparoscopic surgery through laparoscope sheath
Into abdominal cavity.
The thickness of the elastic layer is slightly larger than the thickness of confining layers, to fully ensure that 1 inner wall of air bag to 4 hurtless measure of blood vessel.
The material of the elastic layer can be medical grade rubber or elastic non-woven cloth etc., and in the present embodiment, the material of the elastic layer is preferred
For medical grade rubber.
The utility model is easy to operate, is arranged elastic blocking ring 2 by one end of the air bag 1 in strip, air bag 1 it is outer
Wall is equipped with groove, and the other end of air bag 1 is then passed through elastic blocking ring 2 around blood vessel 4, elastic blocking ring 2 is made to be buckled in groove
It is upper；Since the one side that air bag 1 is close to blood vessel 4 is equipped with elastic layer, the one side far from blood vessel 4 is equipped with the restriction for preventing expansion
Layer, when inflating to air bag 1, elastic layer can make air bag 1 not damage blood vessel 4 when expanding, to 4 hurtless measure of blood vessel, while can be effective
Blood vessel is blocked, more convenient operative doctor is performed the operation；Confining layers can prevent air bag 1 towards expansion outside blood vessel, make only to need when inflation
A small amount of gas can be such that air bag 1 expands toward vessel directions, and then be rapidly achieved the purpose of blocking blood flow, and this saves when inflation
Between, it improves work efficiency.It, only need to be by loading line 3 to air bag 1 since the inner plenum of air bag 1 is connected to loading line 3
It is inflated or deflates, that is, can reach the blood flow for blocking blood vessel 4 or restore the purpose of the blood flow of blood vessel 4, it is easy to operate, it is conducive to hand
The progress of art.It is convenient in laparoscopic surgery to be entered by laparoscope sheath since the air bag 1 of strip is small in inflation front volume
Abdominal cavity after operation, deflates to air bag 1, and 1 volume of air bag reduces, after elastic blocking ring 2 is removed from groove, i.e.,
The utility model can be taken out.
