Description

Dilator

Technical field

This utility model relates to a kind of dilator, belongs to the medical device technology mechanical field.

Background technology

Open in the abdomen operation process at human body, otch need be strutted, make in the body to get a clear view, particularly small incision surgery needs special-purpose otch distraction instrument.Prior art is opened the abdomen operative incision to human body and is strutted, there is not special equipment, carrying out the gripping otch with general pincers class opens to both sides, its defective is that operating theater instruments does not match, particularly little otch, otch opens just more inconvenient, easily causes the otch damage, and the effect of influence operation also prolongs operating time.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of reasonable in design, the dilator that can effectively operative incision be strutted.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of dilator, comprise trumpeter's handle and two trumpeter's handles, one trumpeter's handle is connected by bolt with two trumpeter's handles, it is characterized in that: it also comprises arc device head and tooth plate, arc device head has two, be separately fixed at the front end of trumpeter's handle and two trumpeter's handles, two arc device heads match each other; The end of one trumpeter's handle and two trumpeter's handles is provided with stage clip, and an end of two stage clips is separately fixed on trumpeter's handle and the two trumpeter's handles, and the other end compresses mutually; One end of tooth plate is fixed on two trumpeter's handles, and the other end passes trumpeter's handle; Tooth plate is provided with tooth bar, has latch on trumpeter's handle, and latch snaps in tooth bar and matches each other.

All have arcuate groove on two arc device heads described in the utility model, arcuate groove is configuration, and matches each other.

This utility model compared with prior art has following positive effect: reasonable in design, and can effectively operative incision be strutted, and keep stable, guarantee to perform the operation and carry out smoothly.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the left TV structure sketch map of trumpeter's handle and arc device head among Fig. 1.

Among the figure: 1 one trumpeter's handles, 2 two trumpeter's handles, 3 bolts, 4 camber device heads, 5 tooth plates, 7 latches, 8 stage clips, 10 arc shaped grooves, 11 tooth bars.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment:

Referring to Fig. 1～Fig. 2, present embodiment comprises that mainly trumpeter's handle 1, two trumpeter's handles 2, arc device head 4 and tooth plate 5, one trumpeter's handles 1 are connected also and can rotate by bolt 3 with two trumpeter's handles 2; Arc device head 4 has two, is separately fixed at the front end of trumpeter's handle 1 and two trumpeter's handles 2, and two arc device heads 4 match each other; All have arcuate groove 10 on two arc device heads 4, arcuate groove 10 is configuration, and matches each other.The end that the end of one trumpeter's handle 1 and two trumpeter's handles 2 is provided with 8, two stage clips 8 of stage clip is separately fixed on trumpeter's handle 1 and the two trumpeter's handles 2, and the other end compresses mutually; One end of tooth plate 5 is fixed on two trumpeter's handles 2, and the other end passes trumpeter's handle 1; Tooth plate 5 is provided with on tooth bar 11, one trumpeter's handles 1 and has latch 7, and latch 7 snaps in tooth bar 11 and matches each other.

During use, arc device head 4 is inserted in otch, hold with a firm grip trumpeter's handle 1 and two trumpeter's handles 2 strut arc device head 4, it is fixing with arc device head 4 latch 7 to be snapped in tooth bar 11 again, arc device head 4 is according to the fixed amplitude that struts, otch is strutted, and the doctor undergos surgery in the arcuate groove 10 that struts, and is very convenient; After operation is finished, move down tooth plate 5, latch 7 and tooth bar 11 are thrown off, and under the effect of stage clip 8, trumpeter's handle 1 and two trumpeter's handles 2 reset, and arc device head 4 also resets.

In addition, need to prove, specific embodiment described in this description, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of this utility model patent according to this utility model patent.
