Description
[technical field]
This utility model relates to medical spray line, is specifically related to a kind of scope spray line.
[background technology]
In endoscopic surgery, due to the existence of various body fluid, mucus in human body natural's tract, the scope visual field is produced to impact, improve operating difficulty.For the clear endoscopic surgery visual field, check exactly inside of human body lesion tissue, accurately carry out endoscope operation, the treatment apparatus that needs the cooperation scopes such as spray line to use.This utensil is because of easy to operate, lower-price characteristic, is widely used in the clinical and operation of scope.
Known, existing spray line utensil mainly has following structure: shower nozzle, spray core, flexible sheath pipe, injection interface etc., wherein spray core adopts artificial stranded the forming of some stainless steel silks, and is pressed into shower nozzle inside.Medicinal liquid is filled with and is rushed to shower nozzle by syringe pressure, and through spray core, shunting makes medicinal liquid produce flushing or spray effect.Because the Clinical symptoms of pathological tissues in patient's tract is numerous and complicated, conventional spray line enters after body cavity by scope pipeline, the scope of spray liquid and angle are subject to the unstability restriction of spray core size and produce deviation down to vaporific DeGrain or cause pipeline blockage in shower nozzle, affect sprinkling or developing result, increased the operation easier of scope clinical operation.
In order to solve the problems of the technologies described above, a kind of novel spiral spray core spray line is provided, it has the superior spiral spray core of size, and spray effect is good, and mist pearl is even, and spraying range and angle are accurate, and operation technique is simple and easy controlled.
[summary of the invention]
The purpose of this utility model is to overcome the defect of existing product structure and technology existence, provides a kind of novel spray line, by the novel spray core of shower nozzle inside, to medicinal liquid shunting accurately, spraying range is accurately controlled, and spray effect is good, reduces the operation easier of scope clinical operation.
For achieving the above object, design a kind of scope spray line, comprise shower nozzle, spray core, flexible sheath pipe, protective casing, injection interface and stifle, in shower nozzle, be provided with spray core, it is characterized in that spray core surface is provided with continuous helical structure, spray core embeds in the endoporus of shower nozzle, form spirality pipeline with shower nozzle inwall, described shower nozzle end is provided with pawl structure, flexible sheath pipe is connected with the pawl part of shower nozzle, described injection interface front end is provided with pawl structure, be connected with flexible sheath pipe rear end, described protective casing is coated on the rear end of described flexible sheath pipe, described injection interface rear end is provided with stifle.
Described spray core surface continuous helical structure is double-spiral structure or triple-helix structure.
Described shower nozzle and spray core adopt stainless steel material to make.
Described spray core and spray line shower nozzle are connected.
Described flexible pipe sheath is made up of polytetrafluoroethyltubing tubing.
This utility model compared with prior art, has following characteristics:
1. shower nozzle, spray core preferentially adopt stainless steel material, spray core surface is provided with continuous helical structure, multiple in respect of Double helix and triple helical etc., embed in the endoporus of shower nozzle, form spirality pipeline with shower nozzle inwall, medicinal liquid pressurized, by after spirality pipeline, forms shear action with the spray hole of shower nozzle front end, produces spray effect.When clinical, this structure spray line spray effect is good, and mist pearl is even, and spraying range and angle are accurate, and operation technique is simple and easy controlled;
2. spray core adopts machining, and dimensional accuracy is high, and relatively prior art is affected by human factors lowly, and stability is good;
3. spray core can be used in conjunction with the spray line shower nozzle of various corresponding uses (as surveyed spray, contrary spray etc.), and the suitability is good;
4. spray line flexible pipe sheath is made up of polytetrafluoroethyltubing tubing, and connected position adopts pawl structure, and bonding strength is solid and reliable.
