Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of elastic adjusting type single-chamber sacculus dilating catheter.
Background technology
Sacculus dilating catheter is the soft conduit that a kind of head end carries balloon-expandable, in image-guided lower expansion people
Internal narrow hollow organ, such as alimentary canal, tracheal bronchus, the urinary tract etc..In the case of non-bloating, sacculus dilating catheter
Guided in seal wire or target lesion position is entered by endoscope channel, the sacculus that can be bounced back after treating successfully is led to withdraw from sacculus
Manage external.Sacculus dilating catheter is widely used at narrow aspects of natural cavity such as treatment alimentary canal, tracheal bronchus.
At present, in alimentary canal, stricture of trachea and bronchus surgical procedure, generally require and insert during using sacculus dilating catheter
Guiding wire, targeting moiety could be directed under the monitoring of X developing apparatuses by seal wire guiding by sacculus dilating catheter；Even if logical
Cross endoscope channel and use sacculus dilating catheter, it is also desirable to which sacculus dilating catheter could be directed in targeting portion by being pre-filled with seal wire
Position.Existing sacculus dilating catheter product specification is largely used to alimentary canal, and conduit diameter is generally 2.3mm, can pass through
Endoscope channel enters alimentary canal.When being applied in stricture of trachea and bronchus treatment, it need to be guided by X developing apparatuses and seal wire,
Doctor has inconvenience when in use.
Design is a kind of to be carried seal wire and conduit diameter can be adapted to the sacculus dilating catheter in bronchoscopic forceps road, Ke Yiji
Facilitate use of the doctor in surgical procedure greatly, with larger market prospects.
The content of the invention
The present invention, can be by simple to overcome above-mentioned drawback there is provided a kind of elastic adjusting type single-chamber sacculus dilating catheter
Its guide function is quickly realized in operation, and guidewire proximal is connected provided with flexible member with conduit thereon so that during balloon expandable, elasticity
Element from main regulation, can improve the stability of whole device work, and this dilating catheter is designed using single lumen catheter, is saved into
This, at the same conduit cavity again be provided with multiple tracks reinforcement, can keep product by property, and entirely seal wire only need to be connected to conduit
Distally, seal wire usage amount is saved, production cost has been saved.
To achieve the above object of the invention, the technical solution adopted by the present invention is：A kind of elastic adjusting type single-chamber balloon expandable
Conduit, including seal wire, sacculus, conduit and handle, handle proximate end is liquid injection port, is distally connector, catheter proximal end and connector
Connection, distal outer surface and sacculus sweat soldering, seal wire outer surface are covered with thermoplastic sleeve pipe, and balloon distal and seal wire outer surface heat
Fusion welding, seal wire is provided with coiling integral spring element in its near-end, and flexible member is connected with conduit；
Flexible member can be turn, can be in balloon expandable or contraction, with whole internal pressure and length of balloon
Change is stretched.
Further, conduit is single lumen catheter；
Further, conduit cavity is provided with multiple tracks reinforcement；
Because nothing needs guiding through seal wire in conduit, therefore single lumen catheter just can realize the mechanism of the device, and conduit cavity is provided with multiple tracks
Reinforcement, can keep product by property；
Further, wire distal head is provided with soft head, it is possible to prevente effectively from injury tissue.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
The present invention can quickly realize its guide function by simple operations, can quickly realize that it is oriented to work(by simple operations
Can, guidewire proximal is connected provided with flexible member with conduit thereon so that during balloon expandable, and flexible member can be carried from main regulation
The stability of high whole device work, and this dilating catheter is using single lumen catheter design, it is cost-effective, while conduit cavity is set again
Have multiple tracks reinforcement, can keep product by property, and whole seal wire only needs to be connected to distal end of catheter, saves seal wire and uses
Amount, has saved production cost.
Also, seal wire outer surface is provided with thermoplastic sleeve pipe, when carrying out sweat soldering, agreeing with for high polymer material is more perfect,
The seal and stability of structure are higher, while soft head collective effect is provided with wire distal head, it is possible to prevente effectively from damage
Tissue.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment 1：
A kind of laparoscope cleaning fume extractor is present embodiments provided, shown in Figure 1, handle 1 is bidirectional handle, distally for even
Interface 11, near-end is liquid injection port 12, and the connector 11 of distal end is connected with the near-end of conduit 2, the distal end of the near-end of sacculus 3 and conduit 2
Sweat soldering, and the distal end of sacculus 3 and the distal outer surface sweat soldering of seal wire 4, and the outer surface of seal wire 4 is provided with thermoplastic sleeve pipe, its
Near-end is provided with the flexible member 5 that coiling is molded, and the flexible member 5 is fixed on conduit 2.
Above, because nothing needs guiding through seal wire 4 in conduit 2, therefore conduit 2 uses single lumen catheter, and its inner chamber is provided with multiple tracks
Reinforcement, can keep product by property, be provided with thermoplastic sleeve pipe in the outer surface of seal wire 4, it is to carry out sweat soldering that it, which is acted on,
When, agreeing with for high polymer material is more perfect, and the seal and stability of structure are higher.
The presence of flexible member 5 causes this ball-bag dilation tube independently to carry out flexible adjustment in the course of the work, specifically
, flexible member 5 can be turn, can be when sacculus 3 is expanded or shunk, with whole internal pressure and the length of sacculus 3
Change stretched.
It is preferred that, wire distal head is provided with soft head, it is possible to prevente effectively from injury tissue.
This elastic adjusting type single-chamber sacculus dilating catheter operation principle is as follows：
The seal wire 4 carried can cause dilating catheter without preset seal wire, just sacculus dilating catheter can be directed into target location,
Meanwhile, soft head can be seal wire 4 during guiding, it is to avoid injury tissue, and the thermoplastic sleeve pipe in the outside of seal wire 4 is likewise supplied with this
Function, while seal wire 4 can also be caused to connect compatible degree height during sweat soldering, so that stability is high.
During ball-bag dilation tube is moved to target location, the inner chamber of conduit 3 is provided with multiple tracks reinforcement again, can keep production
Product pass through property.
After sacculus dilating catheter reaches specified location, liquid is injected by liquid injection port 12, liquid enters sacculus from conduit 2
In 3, so that sacculus 3 is expanded, when pressure reaches specified pressure in sacculus 3, implement liquid discharge in operation, subsequent sacculus 3,
Sacculus shrinks.
And during the expansion and contraction of sacculus 3, flexible member 5, preferably turn effect, specifically, sacculus 3 expands
, its diameter is accordingly extended, turn elastic elongation, and sacculus 3 shrinks, and turn is gradually tapered up to initial position.
The technical concepts and features of above-mentioned embodiment only to illustrate the invention, its object is to allow be familiar with technique
People can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent transformation or modification that Spirit Essence is done, should all be included within the scope of the present invention.
