Description
Technical field
The utility model is related to area of medical devices, and particularly a kind of tube chamber that test scope can be facilitated to be unable to reach is narrow
The seal wire of narrow segment length, while can have seal wire proper function.
Background technology
In internal medicine and intervention operation, some places that visualization scope can not be inserted, such as alimentary canal and blood vessel, these
Place just has different degrees of narrow generation in the event of lesion, and such as Digestive Tract Stenosis is largely narrow for esophagus and cardia portion,
Minority is pylorus, duodenum and proctostenosis, and bile duct, treatment method has laser or micro-wave therapeutic, electric knife under scope to cut
Cut and scope under the method such as dilatable bougie, generally for malignant stricture, Stent Implantation can obtain long-term remission after balloon expandable
Effect.Dilating sacculus and support are both needed to clearly correspond to the dimensional parameters of narrow section, and the current dimensional parameters are by under image
Contrast examination is obtained, if contrast agent can not cannot obtain narrow length by narrow, patient body position and perspective during because checking
The reasons such as two dimensional surface, the size is not necessarily accurate.
Utility model content
The purpose of this utility model is that can be convenient for measuring narrow lumen there is provided one kind in view of the shortcomings of the prior art narrow
The seal wire of section size, enables the clinician to obtain more accurate luminal stenosis segment length size, facilitates next step to treat.
In order to solve the above-mentioned technical problem, the utility model provides a kind of seal wire of measurable narrow segment length, including
Axle center, header hose, pyrocondensation epitheca and developing ring, the axle center are tapered by proximate, make distal end relatively soft, easily
Into narrow section, axle center distal bond header hose, for preventing interlayer during operation or causing blood vessel or cavity wall to be perforated.Axle center
Outside is provided with pyrocondensation epitheca, and axle center is arranged at intervals developing ring since the position that distal end is connected with header hose.
Axle center described in the utility model is made up of NiTi class material, it is ensured that the hardness and reversibility of seal wire.
Header hose described in the utility model is made up of polyurethane material.
Pyrocondensation epitheca described in the utility model is made up of PTFE class materials.
Developing ring described in the utility model is made up of the higher metal material of tantalum metal or density.
Axle center described in the utility model sets one to set aobvious since the position that distal end is connected with header hose every 1CM
Shadow ring.The quantity of the developing ring is more than 20.
The a diameter of 3.2F of seal wire described in the utility model, can pass through 5F conduits.
To ensure that development is clear, the width of the developing ring is 1mm, and is annularly fixed on axle center.It is solid and reliable, show
The quantity of shadow ring typically takes 20~25, because the density of tantalum is higher than the density of Nitinol, so now under X-ray development,
The brightness of developing ring is higher than NiTi seal wire, thus there is a clearly scale.
The utility model considers that seal wire can pass through narrow section, and some scale (marks that can develop are increased in wire distal
Note), these scales (mark) can clearly be recognized under development, and accurate size.Measurable length wire energy of the present utility model
Effectively the length of stenosis will directly be accurately measured by cavity narrow, and save the time for changing other apparatuses, reduced
The probability of infection of reporting to the leadship after accomplishing a task, patient trauma is small, and pain is few.
The beneficial effects of the utility model are:Measurable length wire of the present utility model can effectively will be narrow by cavity
Narrow portion, the length of direct measurement stenosis saves the time for changing other apparatuses, reduces the probability for infection of reporting to the leadship after accomplishing a task, patient
Wound is small, and pain is few.
Brief description of the drawings
The utility model is done with reference to the accompanying drawings and detailed description and further illustrated, the utility model
Above-mentioned and/or otherwise advantage will become apparent.
Fig. 1 a are the utility model structure charts.
Fig. 1 b are the utility model sectional views.
Fig. 2 is the utility model front end profile.
Embodiment
Embodiment
As shown in Fig. 1 a (blackstreak in Fig. 1 a is the pattern on seal wire epitheca, non-developing ring) and Fig. 1 b, this practicality
It is new including axle center 4, header hose 1, pyrocondensation epitheca 3 and developing ring 2, the axle center 4 includes internal axle center, and axle center is by near-end
To distal end tapers down, make distal end relatively soft, be easily accessible narrow section, axle center distal bond header hose 1, for preventing operation
When interlayer or cause blood vessel or cavity wall to be perforated.Pyrocondensation epitheca 3 is provided with outside axle center, axle center connects from distal end with header hose 1
The position connect starts to be arranged at intervals developing ring 2.
Axle center 4 described in the present embodiment is made up of NiTi class material.It ensure that the hardness and reversibility of seal wire.
Header hose 1 is made up of polyurethane material described in the present embodiment.
Pyrocondensation epitheca 3 described in the present embodiment is made up of PTFE class materials.
Developing ring 2 described in the present embodiment is made up of the higher metal material of tantalum metal or density.
As shown in Fig. 2 axle center described in the present embodiment is set since the position that distal end is connected with header hose 1 every 1CM
One setting developing ring 2.
To ensure that development is clear, the width of the developing ring 2 is 1mm, and is annularly fixed on axle center 4.It is solid and reliable,
The quantity of developing ring typically takes 20~25, and the present embodiment takes 20, because the density of tantalum is higher than the density of Nitinol, so
Now under X-ray development, the brightness of developing ring is higher than NiTi seal wire, thus there is a clearly scale.
During operation, under the monitoring of scope or x-ray equipment auxiliary equipment, seal wire is inserted along endoscopic biopsy duct, until arriving
Should be noted that up to predetermined position, during insertion should not make seal wire warpage.Conduit is imported along seal wire.Seal wire can be retained when using.Seal wire
Developing ring can be shown in conduit.
Or seal wire is pre-loaded into conduit, under the monitoring of scope or x-ray auxiliary equipment, inserted along endoscopic biopsy duct, directly
To reaching predetermined position.Seal wire can be retained when using.
Seal wire in the utility model, its soft head by the scale foremost of narrow section and seal wire by narrow section when,
Stop insertion seal wire, inject developer, at this moment under development, it may be clearly seen that narrow section, pass through the development on seal wire
Scale, very easily reads the length of narrow, and such doctor can carry out a step therapeutic scheme according to narrow section size
Selection.
Although the utility model is illustrated and described with regard to preferred embodiment, those skilled in the art should manage
Solution, without departing from claim limited range of the present utility model, can to the utility model carry out various change and
Modification.
