Abstract

The utility model discloses a new probe for exploring sinus tract and fistulae, comprising a needle head and a needle shank connected with the needle head. The needle head and the needle shank are molded in one-piece by the silica gel materials. A communicated pipe is arranged in the needle head and the needle shank along the axis, one end of the pipe is opened at the end terminal of the needle shank, and the other end of the pipe is opened on the needle head or the lateral face of the connecting part of the needle shank and the needle head. A length scale mark which can develop the X-ray is arranged on the needle shank. The new probe for exploring sinus tract and fistulae has the advantages of soft texture, convenient operation, satisfying the exploring requirements of different inner diameters with the pipeline type compacting, and facilitating the push-in of the contrast agent for the contrast of sinus tract and fistulae.

Description

The novel probe that is used for probing sinus tract and fistula

Technical field

This utility model relates to medical operating utensil field, especially relates to a kind of novel probe that is used for probing sinus tract and fistula.

Background technology

In surgical operation, often to use probe that sinus tract and fistula are detected; existing probe all is solid metal needle; yet because the complex structure of sinus tract or fistula is various; the metal needle pliability is poor; not only be awkward but also often can not complete probing sinus tract or the fistula channel trend; concrete conditions such as the degree of depth; usually also to could further grasp the structure of sinus tract and fistula in conjunction with contrast agent; and; existing solid probe does not also possess contrast agent is drained into function in sinus tract and the fistula; in addition; use metal needle also easily sinus tract and fistula to be caused damage; therefore, need a kind of quality softness, flexibility is good; easy to use, and be convenient to the novel probe of drain contrast agent.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of novel probe that is used for probing sinus tract and fistula, and its quality softness is easy to operate, can seek and visit needs to satisfy different inner diameters with the conduit types plastotype, and be convenient to push contrast agent and carry out sinus tract and fistulography.

For achieving the above object, this utility model by the following technical solutions:

This utility model probe comprises syringe needle and the needle body that links to each other with this syringe needle, and described syringe needle and needle body adopt silica gel material one-body molded; The conduit of a perforation is set along axis in syringe needle and needle body inside, and this conduit one end opening is in the needle body end, and the other end is opened on the side of syringe needle or needle body and syringe needle coupling part.

Further, being provided with on described needle body can be to the length graduation mark of X ray development;

Further, described length graduation mark is by not made by the heavy metal material that X ray penetrates;

Further, this probe length is 16 ~ 20cm, and the needle body section diameter is 1 ~ 2mm;

Further, this probe also comprises a hollow syringe adapter, and this syringe adapter one end links to each other with described needle body is terminal, and the other end can link to each other with syringe needle.

The beneficial effects of the utility model are: compared with prior art, probe of the present utility model adopts silica gel one-body molded, the quality softness, flexibility is good, thereby easy to operate, can not cause the damage of sinus tract and fistula, can seek and visit needs to satisfy different inner diameters with the conduit types plastotype; Hollow on the structure is carried out sinus tract and fistulogrphy so that push contrast agent; Because needle body is provided with the length graduation mark that can develop to X ray, thereby can verify the location under X ray, makes more convenient to operate.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further described.

Fig. 1 is a front view of the present utility model;

Fig. 2 is an A-A profile of the present utility model.

The specific embodiment

As shown in Figure 1, 2, this utility model comprises syringe needle 1 and needle body 2 two parts that link to each other with this syringe needle 1, and described syringe needle 1 and needle body 2 adopt silica gel material one-body molded; Syringe needle 1 and 2 smooth connections of needle body, syringe needle 1 is a cone, its top is smooth, needle body 2 is a hollow circular cylinder, promptly be provided with the conduit 3 of a perforation along axis in syringe needle 1 and needle body 2 inside, these conduit 3 one end openings are in needle body 2 ends, the other end is opened on syringe needle 1, be provided with on needle body 2 and can use the impenetrable heavy metal material of X ray to apply into this graduation mark 4 to the length graduation mark 4 of X ray development, probe length be about 16 ~ 20cm, diameter is about 1 ~ 2mm, probe also comprises a hollow syringe adapter 5, and these syringe adapter 5 one ends link to each other with described needle body is terminal, and the other end can link to each other with syringe needle.

During use, can according to circumstances make different models, to satisfy the needs of detecting of different inner diameters sinus tract and fistula; Silica gel material quality softness, flexibility is good, can be convenient to the complete passage trend and the degree of depth of seeking and visiting with to crooked 0-180 degree, also can avoid damaging passage; Silica gel material is easily manufactured, and cost is low, and the sterilization of medical silica gel material is convenient, long service life; Probe hollow structurally, syringe adapter can be received the end of needle body 2 in the time of radiography, then syringe needle is inserted in the cavity of syringe adapter 5, contrast agent is pushed into sinus tract by syringe needle 5, conduit 3 to the pushing syringe piston successively and the fistula road carries out radiography; Probe trunk shell carries scale mark, can be convenient to probing sinus tract and the fistula road length and the degree of depth, graduation mark 4 adopts the impervious heavy metal material of X ray to make, therefore under roentgen radiation x, can develop, so just, can under the X line, verify the position of probe, the degree of depth of fistula and sinus tract also comes into plain view, and greatly facilitates operation and use.

As a kind of improvement, can be located at conduit 3 at the opening of syringe needle one end the side of the part that needle body 2 links to each other with syringe needle 1, the opening of opening conduit 3 of syringe needle one end when the side can prevent from pushing contrast agent is blocked by when injected organism tissue, helps the drain of contrast agent.

In sum, novel probe has solved clinical practical problem, has improved diagnostic level, for treatment provides good data, has greatly improved the success rate of operation.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, the modification that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
