Abstract
The invention provides a spraying pipe for an endoscopic surgery. The spraying pipe comprises a handle, an outer pipe, a nozzle and a nozzle sleeve, wherein the handle and the nozzle are connected to two ends of the outer pipe respectively; the nozzle is of a hollow structure and is communicated with the outer pipe, and an opening is formed in the tail end of the nozzle; a plurality of flow guide holes are formed in the side face of the head end of the nozzle; a flow guide groove is formed in the end face of the nozzle and comprises a circular arc groove positioned in the center of the end face of the nozzle and a plurality of guide-in grooves; one edge of each guide-in groove is tangent to the circular arc groove; the guide-in grooves are communicated with the circular arc groove; the flowing directions of liquid medicines, guided into the circular arc groove through the guide-in grooves, in the circular arc groove are consistent; the nozzle sleeve is of a hollow structure, an opening is formed in the tail end of the nozzle sleeve, and the tail end of the nozzle sleeve is connected to the nozzle in a sleeving way; a gap is formed between the inner wall of the side face of the head end of the nozzle sleeve and the outer wall of the side face of the nozzle; a spraying cavity is formed by the gap and is communicated with the guide-in groove and the flow guide hole; a spraying hole corresponding to the circular arc groove in position is formed in the end face of the nozzle sleeve. According to the spraying pipe, a spraying core does not need to be mounted, the resistance of the liquid medicines is greatly reduced, and spray mist which is formed is more uniform and is spirally sprayed out.
Description
Technical field
The invention belongs to medical instruments field, especially a kind of spray line.
Background technology
Spray line is medical apparatus and instruments conventional in endoscopic surgery, for removing the body fluid on lesion tissue position, mucus etc., avoid having an impact to the scope visual field, can the clear endoscopic surgery visual field, be conducive to accurately to endoscope operation, this utensil has the advantages such as easy to operate, cheap, be widely used in scope clinical and operation in.
The spray core that spray line of the prior art comprises handle, outer tube, shower nozzle and is arranged in shower nozzle, modal spray core adopts that some stainless steel silks are manually stranded forms, and be pressed into shower nozzle inside, medicinal liquid fills with punching to shower nozzle by syringe pressure, through spray core shunting, medicinal liquid is produced to rinse or spray effect, this spray core easily causes pipeline blockage in shower nozzle, and spraying range and angle all can be restricted, the effect that impact is sprayed or rinsed; Another kind of spray core adopts spiral spray core, namely spray core is provided with some spiral pipelines, and accurately, operation technique is simple and easy controlled for this spray core spraying range and angle.
But above-mentioned spray line all adopts spray core to be arranged on structure in shower nozzle, adopts this structure, medicinal liquid is very large to the resistance of medicinal liquid in spray core in shower nozzle process, the mist pearl of ejection can be caused uneven, thus affect spray effect.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency that spray core in prior art is larger to medicinal liquid resistance, and provide a kind of endoscopic surgery spray line, this spray line is little to medicinal liquid resistance, can spiral mist pearl, and the mist pearl of ejection is even.
The technical solution adopted for the present invention to solve the technical problems is: a kind of endoscopic surgery spray line, comprise hands handle, outer tube, shower nozzle and nozzle set, described handle and shower nozzle are connected to the two ends of outer tube, described shower nozzle is open-ended hollow structure, and be communicated with outer tube, head end (shower nozzle head end is positioned at outside the outer tube) side of described shower nozzle offers some pod apertures, described shower nozzle end face offers guiding gutter, described guiding gutter comprises the arc groove and some limits that are positioned at shower nozzle end face center and the tangent lead-in groove of arc groove, described lead-in groove is communicated with arc groove, and flow to unanimously in arc groove through the medicinal liquid of some described lead-in grooves importing arc grooves, described nozzle set is open-ended hollow structure, the end of described nozzle set is socketed on shower nozzle, between the inwall of its head end side and the outer wall of shower nozzle side, there is gap, this gap forms spray chamber, described spray chamber is communicated with lead-in groove and pod apertures, and described nozzle set end face has the spray orifice corresponding with arc groove position.The present invention utilizes lead-in groove and arc groove to match and imports medicinal liquid by lead-in groove, due to lead-in groove limit and arc groove tangent, and medicinal liquid flow direction in arc groove that each bar lead-in groove imports is consistent, namely such medicinal liquid defines mist pearl at arc groove inner impact, the curl spraying when spraying.
Further, for improving the connection fastness of handle and shower nozzle and outer tube, the junction of described handle and shower nozzle and outer tube is provided with pawl structure.
As preferably, the connection request of handle and outer tube is higher, and for improving the fastness that handle is connected with outer tube further, described handle and outer tube junction are also provided with protecting pipe, and described protecting pipe is coated on the outside of the outer tube be connected with handle.
As preferably, be simplify structure, described lead-in groove quantity is two, and arranged in parallel.It should be noted that lead-in groove quantity is that two or more has and is applicable to the present invention too, as long as the limit and the arc groove that meet each lead-in groove are tangent, and flow to unanimously in arc groove through the medicinal liquid of some described lead-in grooves importing arc grooves,, but because jet size is less, processing inconvenience, for simplifying structure, lead-in groove quantity is set to two, and arranged in parallel.
Further, for simplifying structure and being convenient to install, described shower nozzle head end outer wall is stepped, and lower diameter is large, and described nozzle set inner diameter is identical with the lower diameter of shower nozzle head end; Certainly nozzle set inwall is arranged to steppedly be applicable to the application too, but due to the parts of spray line all less, this structure processing is inconvenient.
As preferably, can spray from spray orifice smoothly after making the mist pearl of formation, described spray orifice is taper, becomes contraction-like from inside to outside, and its maximum gauge is greater than the diameter of described arc groove.
The invention has the beneficial effects as follows, spray line of the present invention does not need to install spray core, and medicinal liquid reduces greatly at resistance in shower nozzle process, and the spraying of formation is more even, and spiral ejection.
