Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a premixing type endoscope injector.
Background
As is known, medical glue is a new medical product for replacing sewing needles, and the main component of the medical glue is alpha-cyanoacrylate which has the fastest polymerization speed in organism tissues. Under the action of anions in wound surface blood and tissue fluid, the medical glue can be quickly polymerized, solidified and formed into a film and tightly inlaid with the wound surface, the involution state of the wound can be firmly kept, blood cells and blood platelets can be prevented from passing through the adhesive film, small blood vessels fractured on the wound surface can be sealed under the combined action of thrombin and fibrinogen, bleeding can be effectively stopped, tissues and bacteria are isolated by the adhesive film, and the medical glue also has the effects of resisting infection and protecting the wound surface.
When the existing medical glue is used, A, B glue is mostly required to be mixed (ethanethiol (1: 1) N-butyl-2-cyanoacrylate: oil) and then injected into a wound or a place needing hemostasis by a syringe, but the existing syringe is mostly input by a single tube, and the two kinds of glue are injected one by one in batches. In practice, it is found that the glue has a setting time, and when the glue is not mixed with another glue (i.e. not set), the glue injected in advance is likely to flow along with the blood in the blood vessel to shift the hemostasis position, and after the second glue is injected, the glue is coagulated at the place which is not hemostasis to form ectopic thrombus, thus bringing harm to patients.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
In the description of the present invention, it should be noted that the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected unless otherwise explicitly stated or limited. Either mechanically or electrically. Either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1 to fig. 3, the premix endoscope injector provided in this embodiment includes a main flow tube 1 and at least two branch flow tubes 2, wherein a tube diameter of the main flow tube 1 is adjusted according to a size of a biopsy channel or a laparoscope channel of a speculum (laparoscope is less than or equal to 8mm, gastrointestinal scope is less than or equal to 3.8mm, etc.), input ports of the two branch flow tubes 1 are respectively and independently present and correspondingly access corresponding medical glue, outlets of the two branch flow tubes 2 are converged and communicated with an inner cavity of the main flow tube 1, and an injection needle 3 communicated with the inner cavity of the main flow tube 1 is disposed at an end of the main flow tube 1.
When the medical glue injection device is used specifically, the medical glue injection device is integrally arranged in a biopsy pipeline of an endoscope or a laparoscope pore channel in a penetrating mode and pushed to a wound along the biopsy pipeline of the endoscope or the laparoscope pore channel, an input port of the branch pipe 2 is arranged outside, and then corresponding medical glue (namely glue A and glue B) is butted, wherein the medical glue can be a needle tube injector or other instruments capable of injecting the medical glue into the straight flow pipe 2. After the medical glue is injected and is finished, the medical glue can be respectively pushed in the branch pipe 2 and is finally sent into the main flow pipe 1 to be mixed, after the medical glue is mixed, a certain length still exists in the main flow pipe 1, the medical glue (A, B glue) can be premixed in the main flow pipe 1, and then the mixed medical glue can be injected into a wound, so that the mixed medical glue is not retained in the wound of a human body by any one monomer medical glue, and the generation of ectopic thrombus can be avoided.
Further, for making two kinds of medical glue mix more fully, the inner chamber wall of mainstream pipe 2 is provided with spiral ripple 4. Mix the back at medical glue, medical glue still is liquid, and under the effect of thrust, medical glue just can touch with spiral ripple 4 on the mainstream pipe 1, touches the emergence back, and the corresponding reaction force of production that corresponds is in medical glue, and its true production corresponds spiral thrust, and its effort is not the level, consequently produces corresponding stirring to medical glue to alright reach the effect that promotes the mixing dynamics.
Further, for improving the mixing effect of the medical glue, in this embodiment, a stirring member is further specially arranged in the main flow pipe 1, so that after the medical glue discharged by the two branch flow pipes 2 is mixed, the stirring member is driven by the flowing thrust of the medical glue to stir the medical glue.
And as for the stirring member, various structures can be adopted, one of which is: the stirring member comprises a rod body 5, the rod body 5 is arranged in the main flow pipe 1 in an aligned mode, at least one spiral surface 6 is arranged on the surface of the rod body 5, when medical glue mixed liquid is pushed, the medical glue mixed liquid flows along a channel formed by the spiral surface 6 and the inner wall of the main flow pipe 1 (it is required to be noted that the rod body 5 is not fixedly connected with the main flow pipe 1 and can meet the autorotation of the rod body in the flowing process), and after the medical glue mixed liquid flows, corresponding spiral thrust can be generated, so that the stirring effect can be achieved.
In another structure, the number of the stirring members is at least one, and each stirring member comprises a shaft rod 7 and a stirring blade 8, the shaft rod 7 is fixedly or rotatably connected to the inner wall of the main flow pipe 1, and the stirring blade 8 is in a spiral arc surface and is fixedly mounted or mounted on the shaft rod 7 through a sleeve opening 9. The basic principle is the same as the mixing principle, and the medical glue flows through the stirring blades 8 by means of the pushing force column of the medical glue, so that the flowing pushing force acts on the stirring blades 8, and the spiral arc surface design on the stirring blades 8 can enable the flowing medical glue to generate corresponding stirring force.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
