Description
Technical field
The utility model relates to gastrointestinal surgeries, and in particular to a kind of intestinal surgery fistula mouth fistula-building device.
Background technique
In recent years, the disease incidence of colorectal cancer rises in significant, and rejuvenation is presented in incidence trend.Radical-ability knot is straight
Intestinal cancer resection is still to treat the most common method of colorectal cancer.Only operation has cut off cancerous lesions and has cooperated chemotherapy, puts
The measures such as treatment, targeted therapy could really understand carninomatosis stove, the service life for extending patient, the life for improving patient to greatest extent
Treatment
The range of radical-ability Resection for Colorectal Carcinoma includes: intestinal loop where cancerous swelling and its total colectomy mesentery and lymph node.Institute
It leaves the stumps of colorectal cancer patients intestines to draw by abdominal skin to body surface, inflection estimated forms fistula mouth at being sewn on after tortoise neck sample
Place, here it is the fistulization of currently used post operative colo-rectal cancer, it is intended to maximum magnitude cut off colorectal cancer while, build
The channel of vertical patient's defecation, restores the bowel movement function of patient's physiological as much as possible.The indication of enterostomy is main are as follows: 1)
Left side colon acute obstruction wouldn't can be eradicated, can do transverse colon fistulization and temporarily depressurize；2) left colon complicated with acute blocks,
Temporarily decompression or late case are as permanent colostomy；3) colon traumatic rupture or colon, rectum coincide not on the left of
It can temporarily be depressurized when reliable, to guarantee to heal；4) ulcerative colitis, lesion is limited to left hemicolon person, transverse colon fistulization make
Excrement changes its course, and releases the stimulation to diseased region；5) colon, the first stage operation including proctectomy.
But fistulization surgical procedure is complicated, and colon stump is needed to connect with stomach wall in the process, passes through cut-out of performing the operation
Abdominal skin muscle constructs an artificial fistula mouth, could be connected with stump.The mode of the fistula mouth of surgical procedure building at this stage
Or skin is cut by patient in vitro and separates muscle peritonaeum, cuts off a part of skin and muscle to realize, process is more miscellaneous.
There is presently no a kind of fistula mouth fistula-building devices of quickly and easily to operate performing the operation.
Such as the ostomy needle of Patent No. CN201020049957.2 (Publication No. CN201602851U), which uses and wears
Pricker carries out fistulization, and dynamics is smaller when in use for puncture needle, and does not prepare the positioning of fistula mouth, and fistulization process is longer.

Wheel seat connects two handles by two gears, and described two handles are located at the left and right sides of center-pole, and described two handles are logical
Gear is crossed to link with externally threaded engage with the center-pole；
A hollow tube is fixed with below the pinion stand, the hollow bush is located at support rod periphery, the support rod
Upper surface and the bottom of center-pole fix, offer downward opening channel in the support rod, the channel and described logical
Hole conducting, and the internal diameter in the channel is consistent with the internal diameter of the through-hole；
The outer diameter of the center-pole is less than the internal diameter of the hollow tube, and the depth in the channel is not less than the length of the steel needle
Degree.
Further, the upper end of the cutter is equipped with projected direction lower sawtooth blade directed downwardly, under the cutter
End is equipped with the upper sawtooth blade of projected direction upward, and the upper sawtooth blade is engaged with the lower sawtooth blade.
Further, the thickness of the upper sawtooth blade is gradually incremented by from top to bottom, and the thickness of the upper sawtooth blade exists
1mm-5mm；The thickness of the lower sawtooth blade is gradually incremented by from bottom to up, and the thickness of the lower sawtooth blade is in 1mm-5mm.
Further, the outer profile of the cutter is oval, round, any one in rectangle.
Further, the cutter is the cutter of steel.
Further, the upper end of the cutter is fixed on the hollow tube by nut.
Further, the outer diameter of the cutter is between 2cm-10cm.
Further, the handle outer side covering has a non-slip mat.
Further, the support rod is the support rod of steel.
Further, the outer diameter of the steel needle is between 2mm-5mm.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get the utility model respectively compared with
Good example.
The positive effect of the utility model is:
1, the lower end of cutter and steel needle are punctured from centring point on the inside of abdomen and are gone out by the utility model, by steel needle
Top cover in the through-hole of cutter upper end, pull handle then up, center-pole is transported down with the upward of handle
It is dynamic, so that support rod be made to resist the upper end of cutter, and the upper end of cutter is pushed to connect the upper end of cutter slowly
It is bordering on the lower end of cutter, steel needle protrudes into channel with the movement of support rod, until the upper end of cutter and cutting
The lower end of device is closed completely, and fistulization can be completed.
2, the utility model is easy to operate, easily implements.
3, fistula mouth can be quickly made, operation time is reduced.
