Abstract

The utility model provides a kind of special seal wire of Ileus tube, by thick seal wire, seal wire film, thin seal wire, soft conductive filament head composition are gentle excessive for one between thick seal wire and thin seal wire, entire seal wire, which is integrated, to be process, and thick seal wire is wrapped up with thin seal wire by seal wire film, and soft conductive filament head is connect with thin seal wire.The utility model is designed reasonably, gentle excessive for one between thick seal wire and thin seal wire, entire seal wire, which is integrated, to be process, easy to make and at low cost.By the way that seal wire is inserted into conduit during use, soft guidewire sections surmount catheter proximal end.Because before the seal wire being soft seal wire, behind be harder seal wire, conduit can be supported well, while the soft guidewire sections of long-distance sand transport can be carried out, guiding catheter enters pyloric canal, duodenum and barnyard.The utility model is the dual function for having both soft seal wire guiding and stiff guide wire support, can improve the ease-to-operate and success rate of Ileus tube merging.

Description

A kind of special seal wire of Ileus tube

Technical field

The utility model instrument category field of medical devices, is related to a kind of interventional treatment field, applied to intervention doctor in x-ray Lower Ileus tube merging dredging obstruction intestinal tube etc..

Background technology

At present, in intestinal obstruction Case treatment, Ileus tube placement in the treatment art is accepted extensively and is carried out by clinic, special It is not as preferred treatment in the treatment of Adhesive ileus.Ileus tube is a kind of dedicated for therapies for ileus Medical devices by special designing and enteron aisle the wriggling in itself of conduit, voluntarily drive conduit downlink and pass through and block section intestinal tube, So as to have the function that dredging obstruction enteron aisle.There are 2 kinds of methods in the implantation of Ileus tube：Merging and x-ray are underlying under gastroscope Enter.2 kinds of methods respectively have advantage and disadvantage.Implantation is operated by intervening doctor under x-ray：The Ileus tube of seal wire will be configured through patient Side nasal cavity be inserted into, reach stomach by oesophagus, then into conduit guided to the pylorus of stomach under the guiding of seal wire, by pylorus simultaneously Barnyard upper end is reached through duodenum, exits seal wire, fills catheter proximal end water pocket, completes whole operation process.The intestines stalk of merging Conduit gradual downlink of meeting under the wriggling of intestinal tube and the gravity of water pocket is hindered, until by blocking section intestinal tube, reaching dredging intestines The effect of pipe, while the side opening of conduit institute band plays fully drainage enteral and holds and inject the function of nutrients.In merging operation, Seal wire provisioned in Ileus tube used in the clinic hard seal wire thick for 1.24mm at present, front end are soft for 10cm length Seal wire head end, be by tortuous pyloric canal and small with preferable supporting role, but due to the particularity of gastrointestinal tract structure Intestines often encounter difficulties, in order to which by corresponding tube chamber, the technology clinically having to using exchanging pipe is inserted into advance Duodenal nutrition conduit by the guiding of the hydrophilic film seal wire of 0.89mm thicknesses, is placed in 12 by duodenal nutrition conduit In duodenum 12, Ileus tube assorted guide wire is then exchanged by duodenal tube, then intestines stalk is placed under the guiding of seal wire Conduit is hindered, this method is time-consuming, laborious, X-ray exposure time lengthening, while increases the expense of patient.

Invention content

The purpose of the utility model is to overcome the shortcomings of the prior art, provide a kind of Ileus tube special seal wire, By thick seal wire, seal wire film, thin seal wire, soft conductive filament head composition, gentle excessive for one between thick seal wire and thin seal wire, entire seal wire It is integrated and is process, a diameter of 1.2mm-1.5mm of thick seal wire, thin guidewire length is 30mm-45mm, thick seal wire and thin seal wire It is wrapped up by seal wire film, seal wire membrane material selects polyamino resin+surface hydrophilic membrane coat, and surface is smooth, soft conductive filament head and thin seal wire Connection, the diameter of thin conductive filament head is in 0.8mm-0.95mm, and soft conductive filament head diameter is in the junction of thin seal wire and thin seal wire diameter one Size is caused, head-end tapers into, in head end diameter about 0.3mm.

Thick seal wire selects stainless steel material or hard Nitinol material with thin seal wire.Soft 4 material selection polyamine of conductive filament head Resin+surface hydrophilic membrane coat.

The utility model is designed reasonably, gentle excessive for one between thick seal wire and thin seal wire, entire seal wire, which is integrated, to be added Work forms, easy to make and at low cost.By the way that seal wire is inserted into conduit during use, soft guidewire sections surmount catheter proximal end.It because should Be soft seal wire before seal wire, behind be harder seal wire, conduit can be supported well, while the soft seal wire of long-distance sand transport can be carried out Section, guiding catheter enter pyloric canal, duodenum and barnyard.The utility model is to have both soft seal wire guiding to support with stiff guide wire Dual function can improve the ease-to-operate and success rate of Ileus tube merging, save for nearly 1/3 time for entire operation. The cost of manufacture of the utility model compared with the prior art, may save the expense of half seal wire.

Specific embodiment

The utility model is further described in conjunction with the accompanying drawings and embodiments.

Embodiment 1

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model is by thick seal wire 1, seal wire film 2, thin seal wire 3, soft 4 groups of conductive filament head Into the diameter of thick seal wire 1 is wrapped up in 1.2mm~1.5mm by seal wire film 2, and seal wire film 2 selects polyamino resin+surface hydrophilic film Coating material, surface is smooth, the diameter of thin conductive filament head 3 in 0.8mm-0.95mm, thin 3 length of seal wire between 30mm~45mm, It is equally wrapped up by seal wire film 2, there are one gently excessively, be integrated and be process between thick seal wire 1 and thin seal wire 3.Soft conductive filament head 4 It is connect with thin seal wire 3, soft 4 diameter of conductive filament head gradually becomes in the junction of thin seal wire 3 size consistent with thin seal wire diameter, head-end It is small, in head end diameter about 0.3mm.

Thick seal wire 1 selects stainless steel material or hard Nitinol material with thin seal wire 3.Soft 4 material selection of conductive filament head gathers Polyimide resin+surface hydrophilic membrane coat.

Referring to the cross section that Fig. 3, seal wire are formed with seal wire film, show seal wire 5 (being made of thick seal wire and thin seal wire) and lead Cortina 2.

Embodiment 2

When in use, the utility model conductive filament head 4 is passed through into conduit 6, is soft thin seal wire 3 before the seal wire, behind be Harder thick seal wire 1 can allow soft seal wire that can pass through conduit 6 well, carry out gastral cavity and small enteral is remote by operating thick seal wire Distance conveying.After soft seal wire is by corresponding cavity, continues to push stiff guide wire and intestines conduit is guided to enter until reaching ideal area Domain and position.
