A kind of anal fistula dragging lineTechnical field
Technical field of medical instruments is the utility model is related to, particularly a kind of anal fistula dragging line.
Background technology
Anal fistula is the infectious pipeline that anal tube, lower rectum communicate with anal skin, by internal orifice, fistula, the position of collar extension threeComposition, normal recurrent exerbation, does not recover for a long time.Anal fistula is unable to self-healing, it is necessary to operative treatment.
At present, the dragging line clinically used is mostly simple rubber band, so following four be present：1）Present facesBed lacks the anal fistula dragging line dedicated for anal fistula operation, and the diversified in specifications of rubber band can be applied to all treatment requirements surely,So need the anal fistula dragging line of special plurality of specifications；2）The easy aging of simple rubber band, fracture, make operation achievement lose in advanceEffect；3）The overall thickness of rubber band is consistent, it has not been convenient to ligatures；4）Rubber band is inconvenient to drain.
Utility model content
The purpose of this utility model is to provide a kind of easy to use, more preferable anal fistula dragging line of surgical effect.
The technical solution adopted in the utility model is：
A kind of anal fistula dragging line, including elastomeric belt body, its innovative point are：If the surface of the elastomeric belt body laterally offersDry drainage trough, the inner transverse of the elastomeric belt body set the silk thread of several Wave-shaped structurals, the elastomeric belt bodyThe fastener of spherical structure is fixedly installed in both ends, and the elastomeric belt body is integrally formed with fastener.
Further, the silk thread is nonabsorbable surgical suture, and quantity is at least 3.
The beneficial effects of the utility model are as follows：
The utility model is simple in construction, cost is relatively low, is adapted to production extensively, can produce the anal fistula dragging line of plurality of specifications,Meets the needs of different patients；It can be ligatured by fastener, it is convenient to use；Drainage trough can arrange the body fluid of operative siteRelease, be advantageous to the treatment of patient；Silk thread can prevent whole anal fistula dragging line to be broken, Er Qiesi after elastomeric belt body agingInto Wave-shaped structural, the stretching for not influenceing elastomeric belt body uses line.
Brief description of the drawings
The utility model is described in further details with reference to the accompanying drawings and detailed description.
Fig. 1 is the utility model structure diagram；
Fig. 2 is the sectional view of A in Fig. 1.
In figure：1 elastomeric belt body, 2 drainage troughs, 3 silk threads, 4 fasteners.
Embodiment
Described a kind of anal fistula dragging line as shown in Figure 1, Figure 2, including elastomeric belt body 1, if the surface of elastomeric belt body 1 laterally offersDry drainage trough 2, the inner transverse of elastomeric belt body 1 set the silk thread 3 of several Wave-shaped structurals, the both ends of elastomeric belt body 1The fastener 4 of spherical structure is fixedly installed, elastomeric belt body 1 is integrally formed with fastener 4.
In use, can be ligatured by the fastener 4 at both ends, it is convenient to use；Drainage trough 2 can be by the body of operative siteLiquid emits, and is advantageous to the treatment of patient；Silk thread 3 can prevent whole anal fistula dragging line to be broken after elastomeric belt body aging, andAnd silk thread 3, into Wave-shaped structural, the stretching for not influenceing elastomeric belt body 1 uses.
Described above is preferred embodiment of the present utility model, it is impossible to the right model of the utility model is limited with thisEnclose.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified orPerson's equivalent substitution, without departure from the scope of protection of the utility model.
