Technical field
The present invention relates to a kind of medical device, particularly a kind of miniaturization easily support can be inserted human organ
Support inserting device.
Background technology
Existing support inserting device complex structure, including inner tube, outer tube, middle pipe, soft first-class structure, and will ensure
Inner tube diameter can pass through diameter 0.035 " zebra guide wire of (0.889mm) so that interior caliber is larger, cause inner tube with outer
Between pipe, gap reduces, so that the space putting support reduces, designer has to increase outer tube external diameter, has reached loading
The purpose of support.The tissue of much long and narrow bendings in human body so cannot be applied to.
For example, the implantation of trachea bracket is in order to treat malignant disease：As pulmonary carcinoma and benign disease such as tuberculosis etc. cause
Trachea and the method for bronchus luminal stenosis, have obtained the affirmative of medical circle, but the release steps of support are loaded down with trivial details,
Healthcare practitioner has high demands, and patient risk is big.

Put support.Its shortcoming complex steps, does not have the lower accurate positioning of bronchoscope direct-view reliable, and medical personnel and patient are subject to
The shortcomings of radio radiation.
3. the bronchoscope pass by is inserted under directly guiding：Will be equipped with support two-ply plastic be enclosed within bronchoscope or
Support is directly bundled on bronchoscope, discharges support when bronchoscope is inserted through narrow.This method bronchoscope activity
Very flexible, the poor accuracy inserted, and fragile bronchoscope, clinical few application.List of references《Prop up gas
Pipe mirror interventional therapy》
The above tradition method inserted of bronchial stent why using blind put and X-ray examination under discharge, mainly because
Only have φ 2.8mm for electric bronchoscope pincers road is maximum, and traditional bronchus cytoskeletal implanting device external diameter is usually 9Fr (φ
3mm), 10Fr (φ 3.3mm), 11Fr (φ 3.65mm), 12Fr (φ 4mm), therefore cannot put into device and be entered by biopsy channel hole
Enter pathology location.
Again for example, various malignants tumor of digestive tract, in late cases, can cause tight because of the direct invasion of tumor or compressing
Block again, have 40% patients with gastric cancer and 95% to involve duodenal pancreas patient according to statistics and all cannot make radical correction.
Now under selection scope, inner support is inserted is wise, and the narrow positions commonly used at present has：
1) narrow caused by malignant tumor of esophagus；
2) stomach, descendant duodenum, pancreas gallbladder panel of tumor and gastric cancer Post operation anastomotic stricture；
3) malignant tumor of colon obstruction and colonic operation after anastomotic stricture.
The traditional method for releasing of support is at present：First scope is reached pathology stenosis, scope can not be by narrow sexually transmitted disease (STD)
Become, first a zebra guide wire is passed through narrow section, insert plastic bushing along seal wire, inject contrast agent, under x-ray
Determine the lesion locations of far-end, measure the length of whole pathological changes, needed for determining again, the length of support (surpasses up and down
Cross pathological changes 2cm), then TTS inserter is passed through endoscope and reach stenosis along seal wire, then carry out support release.
Content of the invention
Goal of the invention：The technical problem to be solved is for the deficiencies in the prior art, provides a kind of to mount
Enter device.
In order to solve above-mentioned technical problem, the invention discloses a kind of support inserting device, including for placing the outer of support
Pipe, the far-end of outer tube is provided with head construction, is provided with the core being fixedly connected with head construction and middle pipe in outer tube；
When needing to discharge support, head construction, core and middle pipe keep fixed position, and outer tube is dropped back, and support is released
Put, then recall head construction, core and middle pipe.
One of the solution of the present invention, described head construction is hard structure.
The two of the solution of the present invention, described head construction is soft structures, makes inserter have guide function.
Heretofore described head construction deviates from outer tube one end and is provided with the elongated lengthened hose developing, and described core is worn
