Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of single-chamber sacculus dilating catheter for carrying seal wire.
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 single-chamber sacculus dilating catheter for carrying seal wire
Its guide function is quickly realized in operation, and this dilating catheter is designed using single lumen catheter, and cost-effective, guide wire gradual change is thin,
It is kept to pass through performance while the submissive performance for improving product.
To achieve the above object of the invention, the technical solution adopted by the present invention is：A kind of single-chamber balloon expandable for carrying seal wire
Conduit, including seal wire, sacculus, conduit and handle, handle are threeway handle, and it includes the liquid injection port of upper end, the connector of distal end
With the seal wire fixing port of near-end, seal wire outer surface is covered with thermoplastic sleeve pipe, and balloon distal and seal wire outer surface heat fusion welding, and its is near
End and distal end of catheter outer surface heat fusion welding, catheter proximal end is connected with connector, and guidewire proximal can be fixed with seal wire
Mouth adhesive sealing is fixed, and can also be fixed with catheter proximal end；
Further, seal wire proximally can be designed to gradual change fine texture form to distal end, improve the submissive performance of product
It is kept to pass through performance simultaneously；
Further, conduit is single lumen catheter；
Further, when seal wire is fixed with catheter proximal end, inlet is reserved between the two, liquid can enter from the inlet
Sacculus 1；
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, and this dilating catheter is designed using single lumen catheter, is led
Silk is cost-effective using few；Guide wire gradual change is thin, and it is kept by performance while the submissive performance for improving product, also,
Seal wire outer surface be provided with thermoplastic sleeve pipe, carry out sweat soldering when, agreeing with for high polymer material is more perfect, the seal of structure and
Stability is higher, while soft head collective effect is provided with wire distal head, it is possible to prevente effectively from injury 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：
Present embodiments provide a kind of laparoscope cleaning fume extractor, shown in Figure 1, the distal end of sacculus 1 and the outer surface heat of seal wire 2
Fusion welding, near-end and the distal end sweat soldering of conduit 3, the near-end of conduit 3 and the connector 41 of the distal end of handle 4 are fixed, on the middle part of handle 4
End is provided with liquid injection port 42, and near-end is provided with seal wire fixing port 43, and seal wire 2 is specially distal outer surface and the sweat soldering of sacculus 1, closely
End can be fixed with the adhesive sealing of seal wire fixing port 43, can also be fixed with the near-end of conduit 3.
Above, 3 single lumen catheters of conduit, and seal wire 2 proximally can be designed to gradual change fine texture form to distal end,
Keep it by performance while the submissive performance for improving product, thermoplastic sleeve pipe is provided with the outer surface of seal wire 2, carry out thermofussion welding
When connecing, agreeing with for high polymer material is more perfect, and the seal and stability of structure are higher.
When seal wire 2 and the near-end of conduit 3 are fixed, inlet is reserved between the two, liquid can enter from the inlet
Sacculus 1, while because without the usage amount reduction by seal wire 2, then seal wire 2, its cost savings, and the work of conduit 3 in conduit 3
With being then fluid injection, and it can set multiple tracks reinforcement to ensure production in view of the strength problem of conduit 3, in the inside single-chamber of conduit 3
Product pass through performance.
It is preferred that, wire distal head is provided with soft head, it is possible to prevente effectively from injury tissue.
Originally the single-chamber sacculus dilating catheter operation principle for carrying seal wire is as follows：
The seal wire 2 carried can cause dilating catheter without preset seal wire, just sacculus dilating catheter guiding can be put into target location,
Meanwhile, soft head can be seal wire 2 during guiding, it is to avoid injury tissue, and the thermoplastic sleeve pipe in the outside of seal wire 2 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.
After sacculus dilating catheter reaches specified location, liquid is injected into sacculus 1 by liquid injection port 42, sacculus 1 is filled,
Then implement operation, then extract the liquid in sacculus 2 out, sacculus 2 shrinks and taken out.
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.
