Abstract
This utility model relates to the technical field of medical instruments of cardiovascular treatment, particularly a kind of puncture convergent divergent channel of multilayer nest.Its structure comprises handle, the front end of described handle connects convergent divergent channel, described handle rear end is connected with female Luer, described handle and convergent divergent channel center are provided with silk guide passage, convergent divergent channel by tail pipe, sleeve pipe group is nested with puncture tube yi word pattern forms, described tail pipe one end connecting handle, the other end is nested in the rear end of sleeve pipe group, the front end of described sleeve pipe group is nested in the rear end of puncture tube, and described convergent divergent channel is provided with elastic seal ring.The puncture convergent divergent channel of a kind of multilayer nest of the present utility model, it not only can realize the dual function puncturing and expand simultaneously, and can adjust convergent divergent channel length as required, thus is suitable for different operation needs.
Description
Technical field
This utility model relates to the technical field of medical instruments of cardiovascular treatment, particularly a kind of puncture convergent divergent channel of multilayer nest.
Background technology
Puncture dilator is the medical apparatus and instruments of a kind of skin expansion, subcutaneous tissue and the vascular puncture passage used in intervene operation, especially in the operative treatment of cardiovascular disease, generally uses especially.
Existing vascular puncture method mainly contains two kinds, and one uses surgical means to cut skin and subcutaneous tissue, exposes vessel outer wall, use the direct penetration rate of blood tube wall of puncture needle, penetrates after seal wire sets up track, then imports other apparatuses, as conduit etc. along seal wire.The shortcoming of this method is, need surgeon to carry out otch and the stitching of postoperative wound, hands intraoperative blood loss is large simultaneously, and the probability of infection of incisional wound is higher.
Another kind of mode uses puncture mode exactly, directly use puncture acupuncture transdermal, subcutaneous tissue and blood vessel wall, when piercing needle arrives internal blood vessel, penetrate seal wire by pin internal holes and set up track, the shortcoming of this mode is that puncture channel is longer and have larger tightening force, after needing expansion assistive device puncture channel to be expanded, could import follow-up therapeutic device.
Under prior art, there is a kind of puncture convergent divergent channel of taper, its convergent divergent channel entirety is tapered, so just can expand corresponding passage while puncture, realize the multiple function of an apparatus, but this puncture convergent divergent channel entire length is very long, for the human body that some are more shallow, then cannot adjust the length of convergent divergent channel, the scope of application is limited.
Summary of the invention
In order to solve the problem of prior art, this utility model provides a kind of puncture convergent divergent channel of multilayer nest, and it not only can realize the dual function puncturing and expand simultaneously, and can adjust convergent divergent channel length as required, thus is suitable for different operation needs.
The technical scheme that this utility model adopts is as follows:
A kind of puncture convergent divergent channel of multilayer nest, comprise handle, the front end of described handle connects convergent divergent channel, described handle rear end is connected with female Luer, and described handle and convergent divergent channel center are provided with silk guide passage, convergent divergent channel by tail pipe, sleeve pipe group is nested with puncture tube yi word pattern forms, described tail pipe one end connecting handle, the other end is nested in the rear end of sleeve pipe group, and the front end of described sleeve pipe group is nested in the rear end of puncture tube, and described convergent divergent channel is provided with elastic seal ring.
By mutually nested tail pipe, sleeve pipe group and puncture tube, thus the length of whole convergent divergent channel can be controlled by free-extension, make its adjustable length, to adapt to the puncturing operation needs of different depth, elastic seal ring ensure that the level and smooth and sealing of tail pipe, sleeve pipe group and puncture tube junction, thus is convenient to the carrying out of puncture working.
Between tail pipe and sleeve pipe group, between the composition sleeve pipe of sleeve pipe group, and be threaded connection between sleeve pipe group and puncture tube.Be threaded connection and can ensure tail pipe, sleeve pipe group and puncture tube fixing when mutually nested, ensure its firmness.
Tail pipe, sleeve pipe group and puncture tube are all cone, and it is connected to form an overall cone, and the design of cone more makes whole convergent divergent channel external diameter adjustable, with the expansion effect of satisfied different size.
The composition sleeve pipe of sleeve pipe group and the front elevational sectional of tail pipe are ramped shaped, and ramp designs ensure that the smooth connection at tail pipe, sleeve pipe group place mutually nested with puncture tube again.
The beneficial effect that the technical scheme that this utility model provides is brought is:
The convergent divergent channel that this utility model is consisted of tail pipe nested with one another, sleeve pipe group and puncture tube, thus make the adjustable length of convergent divergent channel, and then the expansion effect of different inner diameters size can be selected, meet the use of different surgical depth, different size medical apparatus and instruments, with better function abundant, while reducing medical apparatus and instruments use cost, decrease the operation link of doctor, while shortening operating time, more can reduce the misery of patient.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in this utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the internal structure schematic diagram of the puncture convergent divergent channel of a kind of multilayer nest of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.
Embodiment one
As shown in Figure 1, a kind of puncture convergent divergent channel of multilayer nest, comprise handle 1, the front end of described handle 1 connects convergent divergent channel 2, described handle 1 rear end is connected with female Luer 3, described handle 1 and convergent divergent channel 2 center are provided with silk guide passage 4, convergent divergent channel 2 is by tail pipe 21, sleeve pipe group is nested with puncture tube 22 yi word pattern to be formed, in the present embodiment, described sleeve pipe group is made up of nested before and after two sleeve pipes 23, described tail pipe 21 one end connecting handle 1, the other end is nested in the rear end of sleeve pipe group, the front end of described sleeve pipe group is nested in the rear end of puncture tube 22, described convergent divergent channel 2 is provided with elastic seal ring 5.
For increasing nested fastness, between the sleeve pipe 23 of tail pipe 21 and sleeve pipe group rear end, between the composition sleeve pipe 23 of sleeve pipe group, and be threaded connection between sleeve pipe group and puncture tube 22.
As shown in drawings, the tail pipe 21 in the present embodiment, sleeve pipe group and puncture tube 22 are all cone, and it is connected to form an overall cone.
The composition sleeve pipe 23 of the sleeve pipe group in the present embodiment and the front elevational sectional of tail pipe 21 are ramped shaped.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
