Description

A kind of anorectal probe

Technical field

This utility model relates to a kind of anorectal probe, and this probe can crookedly also can pass through its hollow injection stain or contrast agent to adapt to the fistula tract trend, realizes judging the trend of complicated anal fistula fistula and the position of internal orifice.

Background technology

Anal fistula is anorectal section common disease, wherein Fu Za anal fistula is because fistula tract, collar extension, internal orifice number are more, it is complicated that fistula tract is moved towards, it is long to have the course of disease, the characteristics that are difficult to one-time cure, make patient usually in the hardship of being performed the operation, also will bear heavier financial burden and mental burden; In view of this, the anal fistula treatment is the emphasis and the difficult point of clinical treatment always, the treatment key of success is correctly to judge the trend of fistula tract and the position of internal orifice, wherein, judges that with probe fistula tract trend and internal orifice position are one of clinical important means commonly used.

Chinese patent 95221433 has been announced a kind of pipe plastics disposable anus intestinal probe, this probe is made up of needle handle, needle body, steel wire three parts, its complex structure, because solid wireline does not possess function of injection, be confined to the diagnosis of simple property anal fistula, therefore, the injection of the diagnosis of anal fistula and medicinal liquid needs to be finished jointly by pipe plastics needle body and steel wire; For complicated anal fistula, when using this probe also to be difficult to find internal orifice, also need adopt staining injection stain or lipiodol angiography method to diagnose.But directly cause stain or iodized oil to reveal on the one hand easily from anal fistula collar extension injection stain or iodized oil, stain or iodized oil are difficult to arrive actual anal fistula internal orifice on the other hand, to making the failure of dyeing or radiography.Therefore need provide a kind of more scientific and reasonable, be that probe can be implemented again to dye, the apparatus of radiography, judging complicated anal fistula fistula tract trend and internal orifice position more accurately, thereby improves the cure rate of this disease.

Summary of the invention

Order of the present utility model provides a kind of anorectal probe, this probe can be crooked to adapt to the fistula tract trend, also can pass through its hollow injection stain or contrast agent, realize judging the trend of complicated anal fistula fistula and the position of internal orifice, and then the especially complicated anal fistula of diagnosis and treatment anal fistula.

The purpose of this utility model is achieved by the following technical solution: a kind of anorectal probe, a needle body is arranged, described needle body is flexible hollow circular-tube, and an end of described needle body is the circle obtuse syringe needle, and the other end of described needle body is a needle stand that can be connected with syringe.

In order to make stain or iodized oil can arrive actual anal fistula internal orifice, avoid the failure of dyeing or radiography, described needle body length is 200mm～260mm.

Described needle body length is preferably 200mm, 230mm, 260mm.

In order to make the not only easy bending of described probe but also certain intensity to be arranged, described needle body external diameter is 1.2mm～2.0mm.

Described needle body external diameter is preferably 1.2mm, 1.5mm, 1.8mm, 2.0mm.

Smooth and easy for stain or contrast agent are injected, the intravital hollow diameter of described pin is 0.4～0.7mm.

In diagnostic procedure fistula is caused secondary damage for fear of probe, described syringe needle can be oval spherical.

Described syringe needle can also be a spherical shape.

This utility model compared with prior art has following advantage:

1, anorectal probe of the present utility model is can be arbitrarily crooked to adapt to the fistula tract trend, is connected with syringe more easily to judge the trend and the internal orifice position of complex fistulae with stain or contrast agent through the hollow injection of probe;

2, anorectal probe structure of the present utility model is reasonable, simple, easy and simple to handle, is not prone to secondary damage and stain or iodized oil and reveals, and is easy to numerous medical personnels and grasps;

3, the syringe needle of anorectal probe of the present utility model, needle body, needle stand are structure as a whole, and make easily, and it make for silver material, and pliability is good, and sterilization makes things convenient for, and is easy to clinical expansion.

The specific embodiment

Below in conjunction with drawings and Examples this utility model being done one describes in detail.

Embodiment 1: referring to Fig. 1, Fig. 2, Fig. 3, a kind of anorectal probe has a needle body 2, and described needle body is flexible hollow circular-tube, and described needle body one end is a circle obtuse syringe needle 3, and the described needle body other end is a needle stand 1 that can be connected with syringe; Described needle stand is connected with syringe ozzle insertable.

This utility model can adopt conventional syringe needle manufacture method to make the anorectal probe, and described probe is silver material, and its syringe needle, needle body, needle stand are formed in one.

Do touch and anoscopy during clinic diagnosis earlier and understand situation in the anus, then gauze is rolled into tubular and fills in the anal canal, do not twist fold, insert probe tip this moment along the fistula collar extension, probe into gently, and probe can not be subjected to the influence of fistula bending.When probe meets obstructions can not continue to insert the time, it is retreated slightly, extract the mixed liquor of 1: 2 methylene blue, hydrogen peroxide with the 5ml syringe, syringe is connected with needle stand, slowly inject mixed liquor, must guard against high-pressure injection, injection volume is about 2～5ml.Extract probe subsequently out and compress the fistula collar extension, and gently rub this position, then, roller is pulled out along anal canal, note observing the distance at its coloring site and anus edge, again in conjunction with anoscopy, thus the position of definite fistula internal orifice.With stain by the gauze of syringe pressure injection, to show the internal orifice position of fistula to fistula internal orifice dyeing anal.

When implementing the lipiodol angiography inspection, extract 30%～40% the about 5～10ml of iodized oil with syringe, linking probe slowly injects iodized oil, then, takes positive bit slice and lateral projection, according to contrast examination consequence devised treatment operation plan.

Syringe is connected with needle stand, can be in fistula pressure injection distilled water pipe blow-through, also can realize that medicine takes off Tube Drain to the intrinsic pressure injection thing of fistula.

In the present embodiment, described needle body preferred length is 200mm, 30mm, 260mm.

In the present embodiment, described needle body external diameter is preferably 1.2mm, 1.5mm, 1.8mm, 2.0mm; Can select to use according to the characteristics of different cases.

Embodiment 2: referring to Fig. 4, present embodiment is the improvement on embodiment 1 basis, in diagnostic procedure fistula is caused secondary damage for fear of probe, and described syringe needle 4 can be oval spherical.

Embodiment 3: referring to Fig. 5, present embodiment is the improvement on embodiment 1 basis, and described syringe needle 5 can also be a spherical shape.

Science and practicality in order to prove anorectal probe of the present utility model are summarized as follows a large amount of clinical experiments:

This group has patient's 240 examples, wherein, and male 150 examples, women 90 examples; Between year, the mean age is 46.8 years old to patient age at 8-65; Patient's course of disease is half a year to 15 year; In the middle of above-mentioned case, the complicated anal fistula of low level has 130 examples, and high-order complicated anal fistula has 110 examples; Above-mentioned case all adopts anorectal probe combined staining agent of the present utility model or contrast agent to make a definite diagnosis the whole one-time cures of operative treatment.
