Description
Technical field
The utility model belongs to medical instrument technical field of auxiliary equipment, more particularly to a kind of shaping flexibility suction tube group
Part.
Background technology
With the development of science and technology, World Medical health level increases substantially, especially surgical field, micrurgy
It is generally to carry out with endoscopic surgery.Field of neurosurgery, micrurgy have been popularized in past 50 years, endoscopic surgery
It is grown rapidly in past 15 years, equipment and surgical technic make rapid progress.Micrurgy and endoscopic surgery, there are one common ground
It is exactly " minimally invasive ", the excision of lesion or the treatment of disease is completed with the wound of very little；And " minimally invasive " also brings another jointly
Point is exactly operative space " narrow ".
Currently, the especially micrurgy or endoscopic surgery of the section office such as neurosurgery, Head and neck tumour and vascular surgery, due to
Operating space " narrow " is typically only capable to accommodate people's operation；And in the course of surgery, due to：(1) bleeding of operative site,
Cerebrospinal fluid secretion, tissue fluid exudation；(2) it is moistening, protects normal structure and reduce the high temperature of the generations such as bipolar coagulation to normal
The damage of tissue, the flushing liquor of persistently small flow is given in art, and the accumulation of aforesaid liquid can obscure operation interface, cover and close on
Tissue.A kind of settling mode is that patient frequently interrupts procedure, and hematocele and cerebrospinal fluid, flushing liquor etc. are absorbed with hand-held suction tube
Liquid, this can influence the operation of patient's normal surgical, extend operating time, increase operation risk；Another way is held by assistant
Aspirator auxiliary attracts, but due to narrow space, this mode interferes patient's operation, and waste of manpower.
Utility model content
The purpose of the utility model is to overcome the drawbacks described above of the prior art, a kind of attraction tube assembly is provided to absorb visual area
The liquid gathered in range, the suction tube is flexible pipe, but can mould different shape according to actual needs, and be may be implemented solid
Determine without man-hour manually hand-held.
The technical solution of the utility model is achieved by the following way.
A kind of shaping flexibility attraction tube assembly, the component include suction tube and guiding pipe sleeve；The suction tube is soft
Property pipe, on tube wall fusion the pliable shaping metal silk of 1-3 roots is distributed with；The suction tube includes intermediate tube body, the suction side of one end
With the connecting pin of the other end；The suction side is within the scope of pipe end 1mm without the pliable shaping metal silk, the suction side
With several suction holes；The connecting pin is the Quick Release connection-peg for connecting aspirator relay pipe；The angled α of guide pipe tackling
Side opening bend pipe, it is described be oriented to pipe sleeve can be socketed in by the side opening suction tube intermediate tube it is external.
Further, further include the fixing piece for fixing the guiding pipe sleeve outside the guiding pipe sleeve.
Further, the fixing piece is across the adhesive tape of guiding pipe sleeve and both ends with preset adhesive glue.
Further, the fixing piece is across the fixation band of guiding pipe sleeve and both ends with suture eyelet.
Further, ranging from 70-120 ° of the angle [alpha] for being oriented to pipe sleeve, the length at bend pipe angle both ends are respectively
The internal diameter of 10-15mm, the guide sleeve are bigger 0-0.2mm than the outer diameter of suction tube.
Further, the attraction pipe range 15-25cm, lumen diameter φ are less than or equal to 3.0mm, pipe thickness 0.25-
1.0mm。
Further, on the tube wall fusion be distributed with the pliable shaping metal silk of 1-3 roots be wire be embedded in tube wall, or
Person's wire is distributed in outside tube wall and is integrally formed using with tube body same material package and with tube body；When easy using 2 or 3
When curved shaping metal silk, it is uniformly distributed in 180 ° or 120 ° on tube wall periphery.
Further, the pliable shaping metal silk be aluminium wire, tin silk, copper wire or filamentary silver, the pliable shaping metal silk
A diameter of φ 0.25-1.0mm.
Further, the suction hole is distributed within the scope of the inside 10mm of pipe end, described several for 1-3 rows, the total 1-9 of 1-3 row
A uniformly distributed hole.
Further, a diameter of φ 0.5-1mm of the suction hole.
The design of technical solution of the present invention is based on following consideration：
In order to adapt to different operation demands, the utility model suction tube uses flexible design, such as may be used
Prepared by silica gel material, while if whole too soft, being unfavorable for keeping proper shape, is merged on tube wall thus appropriate easy
Curved shaping metal silk, such as wire prepared by aluminium or tin or copper or silver or other materials, operative site as needed can be with
Easily be bent it is moulding, meanwhile, shape after bending can also be kept after bending.Due to being used for micro- or endoscopic surgery, skin
Surface art mouth is smaller, and suction tube will inevitably have the part of bending, and when use flexible material, the part of bending is possible to
Pipeline is set to be built up closure, for this purpose, the utility model matching design guiding pipe sleeve, in the big place of bending angle using leading
To casing protect, be blocked caused by avoiding pipeline from folding.
According to neurosurgery, the ordinary circumstance of Head and neck tumour, vascular surgery, from human skin to art area depths apart from about
10-15cm.Due to there is the connection of " relaying general attraction long tube " between suction tube and aspirator, the utility model design
Shaping flexibility attract pipe range 15-25cm.In order to meet usual drainage flow, and it is not take up visual area space；It can be with smaller
Tension keeps the shape needed, is less than or equal to 3.0mm to design suction tube lumen diameter, caliber is less than or equal to 4.0mm；It is preferred that
The lumen diameter used is 1-2mm.
Wire can be embedded in tube wall or wire is distributed in outside tube wall simultaneously according to the needs of preparation process
Using wrapping up with tube body same material and being integrally formed with tube body, considers easily moulding and support strength combination, choose diameter
The wire of 0.25-1.0mm, specific diameters depend on the diameter and wall thickness of suction tube.Thicker suction tube uses relatively thick gold
Belong to silk.
And preventing the wire of suction tube from being impacted to art area, wire is terminated in pipe end about 1mm inwardly, simultaneously
In order to preferably be absorbed to art area hydrops, in suction tube head end 10mm, design 1-3 row, 1-3 arrange suction hole, according to suction
Skirt diameter can set a diameter of 0.5-1mm of suction hole.
The utility model has the advantages that：
1) in the prior art, the similar devices of same structure are not reported both at home and abroad, and the utility model has higher
Innovation height.
2) suction tube of the utility model is used, it can be achieved that art area is without hematocele, hydrops so that the cleaning of art area, apparent, improvement
Patient, which performs the operation, to be experienced；Also, it no longer needs to individually carry out washing lotion and interrupt Advances of operative technique, accelerates procedure, mitigate patient's fatigue,
Improve procedure efficiency and operation safety.
3) the utility model is simple in structure, and the material of use is harmless, securely and reliably, easy to use.
4) the utility model is widely used, the micrurgies such as neurosurgery, Head and neck tumour, vascular surgery and endoscopic surgery field
Conjunction can use.
