Abstract
The invention relates to a reducible vessel blocking device which comprises a water cell, and the water cell is provided with a gas injection pipe communicated with the water cell. The invention has simple structure, convenient use and obvious reducible blocking effect.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of recoverable vascular blocking device.
Background technology
When carrying out some surgical operations, carry out clamping after needing the vein that will have and arteries to peel off, be convenient to observe patient's reaction and make corresponding emergency treatment.Recoverable vascular blocking-up method commonly used at present mainly contains:
1, tiretube process.Referring to Fig. 1, it is to utilize operating theater instruments to peel off blood vessel, ligature is passed from the blood vessel bottom, ligature two of passing blood vessel mentioned pass resilient sleeve pipe in the lump, utilize mosquito forceps to clamp telescopic end, utilize another mosquito forceps slowly blood vessel to be pushed along the sleeve pipe direction simultaneously, spring-backed quill is owing to self have elasticity, in the process of extruding, free blood vessel is carried out the recoverability blocking-up.Can't accurately control occluding pressure during this method blocking-up blood vessel, and ligature is thinner, hurts blood vessel easily, especially when blood vessel wall approaches or inflammatory edema is arranged.And complicated operating process, use inconvenience, poor effect have prolonged the operation preorder time, have influenced the operation process.
2, chucking method.This method is to adopt a thin expansible air bag that has clip that blood vessel is carried out direct clamping, the collet segment broad of this clip, scope is less can't settle when blood vessel dissociates, need other medical worker to cooperatively interact during operation to obtain to the clamping of blood vessel or lax, the bad control of occluding pressure, and the easy damaged blood vessel uses inconvenient.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the background technology, the invention provides a kind of simple in structure, easy to operate, tangible recoverable vascular blocking device of barrier effect.
Technical solution of the present invention is: the invention provides a kind of recoverable vascular blocking device, its special character is: described recoverable vascular blocking device comprises water pocket; Described water pocket is provided with coupled logical water injection pipe.
Above-mentioned water pocket is provided with locking device.
Above-mentioned locking device is a lock valve.
Also be provided with scale on the above-mentioned water pocket.
The end of above-mentioned water injection pipe is provided with automatic lock valve.
Above-mentioned water pocket is strip or ellipticity.
Advantage of the present invention is:
1, simple in structure.The present invention directly is provided with water pocket on ligature, simplified the various apparatuses that adopted in the existing tiretube process greatly, make simple in structure, can be rapidly recoverable vascular blocking-up to peeling off, shortened the operation preorder time greatly.
2, easy to operate.The present invention directly is provided with water pocket on ligature, after the air injection pipe that utilization is connected with water pocket was injected air or liquid, water pocket can expand rapidly, and the water pocket after the expansion pushes blood vessel, the recoverability blocking blood flow, and it is quite convenient to operate.
3, the recoverability barrier effect is remarkable.The present invention utilizes water pocket to come the blood vessel of peeling off is carried out the recoverability blocking-up, for the situation that the rapid recoverability blocking-up of needs blood vessel comes block blood to circulate, and can be rapidly to water pocket inflation or injection liquid; For needs slowly recoverability blocking-up blood vessel come the situation of block blood circulation, can be slowly to the water pocket inflation or inject liquid.Can control the size of water pocket at any time and judge the physiological reaction of patient at recoverability blocking-up blood vessel, the recoverability barrier effect is quite remarkable.
Description of drawings
Fig. 1 by in the prior art the employing tiretube process to the structural representation of recoverable vascular blocking-up;
Fig. 2 is the structural representation of recoverable vascular blocking device provided by the present invention;
Fig. 3 is a user mode reference diagram of the present invention;
Fig. 4 is the A-A phase view of Fig. 3.
The specific embodiment
Referring to Fig. 2, the invention provides a kind of recoverable vascular blocking device, this recoverable vascular blocking device comprises water pocket 2; Coupled logical air injection pipe 3 is arranged on the water pocket 2.
The end of air injection pipe 3 is provided with automatic lock valve 4, can prevent to inject the air or the leaked liquid of water pocket 2.Water pocket 2 can be other analogous shapes such as strip, ellipticity.On water pocket 2, lock valve 5 can be set, be used for after ligature passes blood vessel 6, containing water pocket 2 and lock, can replace the function of mosquito forceps in the prior art two.
Participate in Fig. 3 and Fig. 4, the present invention in use, the present invention is passed from blood vessel 6 bottoms that separate, utilize the air injection pipe 3 that is connected with water pocket 2 to inject liquid then to water pocket 2, utilizing a mosquito forceps will contain water pocket 2 clamps, water pocket 2 expands rapidly under the condition that has air or liquid to exist, and is strip or this ellipticity, water pocket 2 after the expansion can push its inner blood vessel 6, make that blood vessel 6 is firmly clamped, reach the hemostatic function, simultaneously, can be according to the needs swelling degree of regulating water pocket 2 of operation, for more accurate, on water pocket 2, also be provided with scale 1, when lock valve 5 from the side initiating terminal (being 0 scale) of water pocket 2 when clamping the opposite side of water pocket 2, can be according to the scale 1 of lock valve 5 at water pocket 2 opposite sides, judge the force value of blood vessel, promptly to the pine of blood vessel clamping with tight, it is quite convenient to use.Certainly on water pocket 2, be provided with locking device again, all can realize the function of recoverable vascular blocking device of the present invention such as lock valve 5 grades, the function that just can replace mosquito forceps, and make the present invention more convenient in the process of using, can simplify the preorder work of operation greatly, shorten operating time.
