Description
Technical field
This utility model relates to that a kind of belt carcass thigh is quiet, arterial cannulation, belongs to technical field of medical instruments.
Background technology
At present, along with the development of cardiac operation is perfect, so far, nearly all congenital heart disease, coronary heart disease, valvular heart disease can both obtain treatment by traditional extracorporeal circulation menisectomy, meanwhile, along with the continuous prosperity of medical science and technology, in the industry except pursuing good surgical outcome, also wish operation risk to be reduced to bottom line, and will consider the aesthetic problem of rear wound.Department of cardiac surgery is also the same with other field, has also become a kind of inexorable trend to Wicresoft's future development.As the indispensable apparatus of minimally invasive cardiac surgery, how to develop that a kind of perfect belt carcass thigh is quiet, tremulous pulse arteries and veins intubate, possess in operation in the major function of the human body that reinjects after good oxygenate outside blood lead body to realize, have the reasonability of self structure concurrently, be an important research direction in the industry always.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, provides that a kind of belt carcass thigh is quiet, arterial cannulation, and it can be applicable to the Minimally Invasive Surgery under the specular state in complete chamber, realize the object that does not need open chest surgery, and result of use is good.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of belt carcass thigh is quiet, arterial cannulation, it comprises guiding core, intubate body and two-way helmet pipe that can external connection body outer circulation pipeline, the head of guiding core is provided with puncture tip, its afterbody is provided with guiding cap, and guiding core has and runs through guiding core and supply the interspersed core chamber of guide wire, intubate body has the drainage lumens that runs through intubate body, described guiding core is inserted in drainage lumens movably, on the sidewall of the head of intubate body, have multiple conduction holes that are connected with drainage lumens, the afterbody of intubate body is arranged on two-way helmet pipe, on the sidewall at the middle part of intubate body, be provided with reinforcement supporting wire.
Further reach effect attractive in appearance and be beneficial in importing blood vessel in order to meet human engineering, the middle part of described intubate body is the large structure of the little back segment of leading portion.
Adopt after technique scheme, the conduction hole of the head of intubate body of the present utility model can be retrieved blood resistance to prevent hypertension, be convenient to insert blood vessel, the middle part of intubate body adopts reinforcement supporting wire to carry out Design of Reinforcement, can ensure the high flow capacity of blood, can the in the situation that of negative pressure, not make again body collapsing, adopt this utility model can pass through Minimally Invasive Surgery, insert blood vessel, realize extracorporeal circulation, thereby can be applicable to the Minimally Invasive Surgery under the specular state in complete chamber completely, realize the object that does not need open chest surgery, and result of use be good.
Brief description of the drawings
Fig. 1 is that belt carcass thigh of the present utility model is quiet, the structural representation of arterial cannulation;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Detailed description of the invention
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail below,
As Fig. 1, shown in 2, a kind of belt carcass thigh is quiet, arterial cannulation, it comprises guiding core 1, intubate body 2 and two-way helmet pipe 3 that can external connection body outer circulation pipeline, the head of guiding core 1 is provided with puncture tip 1-1, its afterbody is provided with guiding cap 1-2, and guiding core 1 has and runs through guiding core 1 and supply the interspersed core chamber 1-3 of guide wire, intubate body 2 has the drainage lumens 2-1 that runs through intubate body 2, guiding core 1 is inserted in drainage lumens 2-1 movably, on the sidewall of the head of intubate body 1, have multiple conduction hole 2-2 that are connected with drainage lumens 2-1, the afterbody of intubate body 1 is arranged on two-way helmet pipe 3, on the sidewall at the middle part of intubate body 2, be provided with and strengthen supporting wire 4.
Reach effect attractive in appearance and be beneficial in importing blood vessel in order to meet human engineering, as shown in Figure 1, the middle part of intubate body 2 is the large structure of the little back segment of leading portion.
Operation principle of the present utility model is as follows:
While carrying out operation on heart, first intubate body 2 is inserted in to guiding core 1, guiding core 1 is inserted into the position that heart needs drain along femoral vein or femoral artery, under the guiding of guiding core 1, be inserted to the position that needs drain, extract guiding core 1 out, retain intubate body 2, and adopt pliers to clamp the afterbody of intubate body 2 simultaneously, two-way helmet pipe 3 is accessed to extracorporeal circulation pipeline, thereby realize the drain in operation on heart, more convenient, realize the object that does not need open chest surgery, can be applicable to the Minimally Invasive Surgery under the specular state in complete chamber.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that this utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
