Description
Technical field
The present invention relates to a kind of vascular pattern that is mainly used in the purposes such as the performance test of arterial intervention operating theater instruments, apparatus parametric measurement, surgical simulation experiment, more particularly, relate to a kind of blood circulation simulating device that uses this vascular pattern to carry out Wicresoft's interventional therapy simulated experiment.
Background technology
Due to population aging increasingly, the rising of the incidences of disease such as hypertension, diabetes, high fat of blood, and the developing rapidly of diagnostic imaging, the incidence of disease and the discovery rate of arterial disease raise day by day.The process that adopts traditional prosthetic vessel replacement to treat is very complicated, wound is large, mortality ratio is high, and adopt endovascular graft intervention intravascular stent to carry out minimally-invasive treatment, there is safe and effective advantage, thereby by most doctors and patient, accepted, become the primary treatment method of arterial disease.Especially for advanced age and the many patients of complication, first-selected especially, or even unique cure method.
Thing followed problem is need to be by intravascular stent safety smooth and easy and be delivered to exactly arterial vascular lesion locations, this just requires endovascular graft to get involved intravascular stent and induction system is provided with professional test device, this device energy sham operated condition test support and induction system performance parameter; Meanwhile, operator can be familiar with internal blood vessel structure and blood circulation process, and can skillfully intravascular stent be got involved to human vas quickly and accurately, with in low damage, few vascular diseases for the treatment of painful in the situation that.Obviously, by static blood vessel picture, can not effectively make operator there is aforementioned capabilities already.
At present, comparatively effectively the operation training of arteries Wicresoft interventional therapy operation and experiment are mainly to complete by zoopery, yet animal blood vessels experiment has gap after all with human vas experiment, and zoopery cost is higher, the repeatability of operation technique exercise is low, operative process is not directly perceived, and aligning is really executed Wicresoft's intervene operation and brought equally certain influence.
Summary of the invention
It is a kind of transparent that one object of the present invention is to provide, and clear and intuitive and with low cost, reusable vascular pattern, by inject simulate blood in this model, can show sanguimotor process intuitively.
For this reason, vascular pattern provided by the invention is by the machine-shaping of transparent or semitransparent material simulation human aortic blood vessel, and is designed to detachable split-type structural, and the vascular pattern after moulding can have respectively aorta pectoralis and abdominal aorta.In addition, described vascular pattern also can further comprise and being connected with abdominal aorta with aorta pectoralis and detachable bifurcated artery vascular pattern.Such design can split this vascular pattern according to actual needs, to be simulated for the blood circulation of aorta pectoralis or abdominal aorta and each bifurcated artery thereof especially.
Preferably, the character such as the hardness of described transparent or semitransparent material, surfaceness, toughness and elasticity are similar to the character of human body artery blood vessel, thereby are convenient in intervene operation, experimental performance parameter be measured.In addition, can by the ratio setting of described vascular pattern, be also advantageously identical with the arterial vascular ratio of normal human, true sense organ when increase operator tests.
In order to guarantee the smooth circulation of simulate blood, the inner chamber of described vascular pattern should be set to unobstructed, and preferably on model the opening part of each bifurcated artery vascular pattern of corresponding arteries be provided with removable sealing-plug.
Alternatively, described transparent or semitransparent material can be selected from the soft macromolecular materials such as soft PVC, silicon rubber.
Another object of the present invention is to provide a kind of blood circulation simulating device, by means of this analogue means, capable of dynamic shows the blood circulation process in blood vessel, particularly can carry out blood vessel by operating this analogue means, especially the interventional therapy simulated experiment of arterial vascular Wicresoft, greatly improves operator's clinical operational skill.
For achieving the above object, blood circulation simulating device provided by the invention comprises experimental implementation case, holds liquid case and main control system, this main control system with hold liquid case and be connected for control simulation blood supply and discharge, wherein, in experimental implementation case, be placed with and the foregoing vascular pattern that holds liquid case sealing and be communicated with, on described experimental implementation case, be also provided with the opening that mis instruments gets involved, this opening can be sealed.In one embodiment, this opening can seal by adding for example packoff of O-ring seal type; In another embodiment, can preferably adopt for example rubber plug to carry out sealed open.Under latter event, mis instruments can directly be passed packoff, and the incision size forming while entering packoff due to mis instruments is very little, so still can keep the sealing state of experimental implementation case inside, and this set is very beneficial for recycling of control box, and cost effectively reduces.
In one embodiment, described experimental implementation case can be hierarchy, comprises blood vessel simulation layer, pipeline layer and drain layers etc.Wherein, blood vessel simulation layer is mainly operation technique Experimental Area, for placing described vascular pattern, with clear and intuitive instant situation of observing simulate blood and operation technique experiment; Pipeline floor is mainly placed the pipeline floor on simulation blood transportation tube road, so that the pipeline of whole equipment is regular, concentrate on compactly this layer, when analogue means has the blood analog functuion of numerous capillaries, this layer is particularly favourable; Drain layers is mainly used in cleaning to simulate blood after experiment, clean in order to the liquid in whole device is all got rid of, and prevents liquid corrosion equipment.
Advantageously, described experimental implementation case is made by transparent or semitransparent material, and operator can observe described vascular pattern intuitively by the transparent or semitransparent upper cover of this experimental implementation case.
More preferably, experimental implementation case can be made by transparent or semitransparent macromolecular material.Like this, blood circulation simulating device of the present invention can carry out pivot operation under X-ray machine, because experimental implementation case and vascular pattern all do not comprise hardware, operator can only see the shape of vascular pattern and the blood circulation process of dynamic similation wherein under X-ray, has effectively realized the realistic simulation to true surgical environments.
Further, described main control system can comprise control circuit, the hydraulic pump being connected with control circuit, monitoring element, and corresponding Electronic Display Panel and regulation and control button, wherein this monitoring element respectively with control circuit with hold liquid case and be connected for monitoring simulate blood temperature and hydraulic pressure, hydraulic pump can be simulated heart and carry simulate blood in vascular pattern.In one embodiment, this hydraulic pump can be positioned over and hold in liquid case, to save accommodation space.Preferably, described monitoring element can be sensor.
Visible, the present invention has mainly solved performance test and the checking of artery Wicresoft intervention apparatus under surgical environments, can be widely used in each scientific research institution and apparatus manufacturing company occasions such as aptitude test to arterial intervention operating theater instruments; Meanwhile, also efficiently solve the problems such as in existing Minimally Invasive Surgery operation practice, cost is high, surgical procedure is not directly perceived, arterial intervention surgery training difficulty, can be used for the intervene operation experiment of arteries Wicresoft, operation technique exercise.
