Abstract
The utility model discloses a kind of endoscopic ligation ring, including the collar（2）And lock body（1）；The lock body（1）It is interior symmetrically to offer left channel（11）And right channel（12）, the left channel（11）And right channel（12）Inside it is respectively provided with lock tooth（13）；The collar（2）Neck be each passed through left channel（11）And right channel（12）And the collar（2）On be respectively arranged with and passage internal lock tooth（13）The sprocket of cooperation（21）.The utility model is reasonable in design, can effectively, must persistently tighten wound location, facilitate endoscopic surgery to be smoothed out, with good actual application value.
Description
Technical field
The utility model is related to the auxiliary implement in endoscopic sinus surgery, specially a kind of endoscopic ligation ring.
Background technology
Endoscopic ligation ring is set bundle, surface of a wound diminution and the perforation suture for being widely used in big polyp during endoscopic surgery
Conventional operating theater instruments, existing ligation ring covered as shown in figure 1, including lock body and the collar, middle part offers a through hole in lock body
Prick after loop section passes through the through hole and form big ring and small ring, big ring is used to tighten suture site, and small ring tightens up big ring for pulling.
When using, big ring sleeve is lived around suture site, device for posting is put into using endoscopic biopsy duct, the small hook in front end of device for posting catches on
Small ring, outer drawing, now lock body maintained static against the front end face of device for posting, continue outer drawing so that big ring progressively reduces to be tightened up, and is entered
And conjunction position will be pricked and tighten up ligation, last device for posting departs from looping and binding device.There is shortcoming in the looping and binding device, when device for posting and looping and binding device are de-
From rear, the extrusion friction effect holding for relying solely on lock body middle through-hole and ligation ring tightens state, but after the time is long, big ring
It is possible to progressively to relax, influences the degree of tightening up of ligation, is unfavorable for the recovery carried out with later stage patient of performing the operation.
The content of the invention
The utility model is easily lax after tightening in order to solve the problems, such as current endoscopic ligation ring, there is provided a kind of new
Endoscopic ligation ring.
The utility model adopts the following technical scheme that realization：
A kind of endoscopic ligation ring, including the collar and lock body；Left channel and right channel symmetrically are offered in the lock body,
Lock tooth is respectively provided with the left channel and right channel；The neck of the collar is each passed through left channel and right side is logical
The sprocket coordinated with passage internal lock tooth is respectively arranged with road and the collar.
It is the same compared with ligation ring when using, first big ring sleeve is lived to prick and close position, it is put into using endoscopic biopsy duct and is inserted
Device, the small hook in front end of device for posting catches on small ring, outer drawing, and now lock body is maintained static against the front end face of device for posting, continue it is outer draw,
The collar under tooth mating reaction so that big ring progressively reduces to be tightened up, and then bundle conjunction position is tightened up respectively by left and right wing passage
Ligation, last device for posting departs from ligation ring.Due to lock tooth and sprocket mating reaction, with stopping function, will not counter motion,
Big ring tightens state in last all the time, relaxation will not occur, using being smoothed out for endoscopic surgery.
The utility model has the following advantages that：
1st, using wiring harness ribbon principle, the big ring of the collar does not relax after tying-off positions, can only prick tighter and tighter, using wound
The stitching processing at place.
2nd, the endoscopic ligation ring low cost of manufacture, beneficial to promoting the use of, also will not substantially increase the medical expense of patient.
The utility model is reasonable in design, can effectively, must persistently tighten wound location, facilitate endoscopic surgery to be smoothed out,
With good actual application value.
Brief description of the drawings
Fig. 1 represents the structural representation of existing endoscopic ligation ring.
Fig. 2 represents endoscopic ligation ring structure schematic diagram described in the utility model.
In figure, 1- lock bodies, 2- ligation rings, 11- left channels, 12- right channels, 13- lock teeth, 21- sprockets.
Specific embodiment
Specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
A kind of endoscopic ligation ring, as shown in Fig. 2 including the collar 2 and lock body 1；The symmetrical left side that offers leads in the lock body 1
Lock tooth 13 is respectively provided with road 11 and right channel 12, the left channel 11 and right channel 12；The neck portion of the collar 2
The sprocket 21 coordinated with passage internal lock tooth 13 Chuan Guo not be respectively arranged with left channel 11 and right channel 12 and the collar 2.Set
After ring 2 passes through left and right side passage 11,12, one end forms big ring, and the other end then forms small ring, and big ring is used to tighten suture site,
Small ring tightens up big ring for pulling.The similar wire harness with for arranging cotton rope of the mating reaction of sprocket and passage internal lock tooth on the collar
Band, harness band is that nylon material makes, for tying up the belt of thing.
When using, first big ring sleeve is lived around suture site, device for posting is put into using endoscopic biopsy duct, before device for posting
Hold small hook to catch on small ring, outer drawing, now lock body maintained static against the front end face of device for posting, continue it is outer draw, the collar passes through respectively
Left and right wing passage, under tooth mating reaction so that big ring progressively reduces to be tightened up, and then ligation is tightened up at bundle conjunction position, it is most rearmounted
Enter device and depart from looping and binding device.Now, big ring will not relax all the time in state is tightened.
During specific implementation, the collar 2 is made using nylon rope.
As described in Figure 2, left and right wing passage passes through the passage of lock body beneficial to the collar in being symmetrically obliquely installed, and conveniently makes
With.
Finally it should be noted that above example is only used to illustrate the technical solution of the utility model and unrestricted, although
It has been described in detail with reference to the utility model embodiment, it will be understood by those within the art that, to the utility model
Technical scheme modify or equivalent, without departure from the spirit and scope of the technical solution of the utility model, its is equal
In should covering claims of the present utility model.
