Abstract

The utility model claims an esophagojejunostomy ligating band comprising a band body and a tightening head connected with one end of the band body. One side of the band body is distributed with ratchets along the length direction, the ratchet face of the ratchet is inclined towards the tightening head direction, the tightening head is opened with a hole for the passage of the band body, the hole is provided with latches matched with the ratchets internally, and the space formed by the latch and the hole inner wall is identical with the shape and size of the band body. The esophagojejunostomy ligating band of the utility model winds the esophagus or jejunum by a circle then penetrates into the tightening head, the latches in the tightening head are locked tightly unidirectionally with the ratchets on the band body to make the esophagus or jejunum ligated tightly and not loose in a self-lock type ligation. The operation is convenient, rapid and stable and the operation processes are simplified.

Description

Esophagojejunostomy ligation band

Technical field

This utility model relates to technical field of medical instruments, is specifically related to a kind of medical ligation band.

Background technology

In the gastrointestinal resection operation, after stomach or intestinal tube excision, need to rebuild digestive tract, reconstruction mode is respectively esophagojejunostomy, esophagogastrostomy and jejunojejunal anastomsis etc.In coincideing; Earlier in esophagus or jejunum stump, insert resist-nailed seat of anastomat; Sew up esophagus or the ligation of jejunum stump then with fixing nail supporting base, utilize stitching thread back-roll esophagus or one week of jejunum ligation in case of necessity again, tighten nail supporting base; And then use anastomat that esophagus and jejunum are drawn close, coincide.But this coincide and when under peritoneoscope, operating comparatively complicacy, sews up difficulty, and the operating time is long, and ligation is not firm.

Therefore, need to explore a kind of device that can firmly tighten esophagus or jejunum stump fast, make things convenient for operation technique, save operating time.

Summary of the invention

In view of this, this utility model provides a kind of esophagojejunostomy ligation band, can conveniently tighten esophagus or jejunum stump, makes things convenient for operation technique, saves operating time.

The esophagojejunostomy ligation band of this utility model; Comprise belt body and the locking head that is connected with belt body one end; Said belt body one side upper edge tape body length direction is distributed with ratchet, and the flank of tooth of said ratchet tilts towards locking head, has the hole that supplies belt body to pass on the said locking head; Be provided with in the hole with belt body on the latch that matches of ratchet, the space that said latch and hole inwall form is identical with the shape of belt body and size.

Further, said latch is arranged at the side of hole inwall near belt body;

Further, the free end of said belt body is that thin-walled is most advanced and sophisticated;

Further, said ligation band is the plastic tie band.

The beneficial effect of this utility model is: the esophagojejunostomy ligation band of this utility model, and belt body penetrates in the locking head around esophagus or after one week of jejunum ligation, latch in the locking head and the ratchet one-way locking on the belt body; Esophagus or jejunum can only be tightened; Can not unclamp, be the self-locking ligation, convenient to operation; And firm, saved operation technique.

Description of drawings

For the purpose, technical scheme and the advantage that make this utility model is clearer, will combine accompanying drawing that this utility model is done further to describe in detail below, wherein:

Fig. 1 is the vertical view of this utility model;

Fig. 2 is the longitudinal sectional view of this utility model;

Fig. 3 is the ligation state diagram of Fig. 2.

The specific embodiment

Below will be with reference to accompanying drawing, the preferred embodiment of this utility model is carried out detailed description.

Fig. 1 is the vertical view of this utility model, and Fig. 2 is the longitudinal sectional view of this utility model, and Fig. 3 is the ligation state diagram of Fig. 2; As shown in the figure; The esophagojejunostomy ligation band of this utility model comprises belt body 1 and the locking head 2 that is connected with belt body 1 one ends, and said belt body 1 one side upper edge belt body 1 length direction is distributed with ratchet 11; The flank of tooth of said ratchet 11 tilts towards locking head 2; Have the hole 21 that supplies belt body 1 to pass on the said locking head 2, be provided with in the hole 21 with belt body 1 on the latch 22 that matches of ratchet 11, said latch 22 is identical with size with the shape of belt body 1 with the space that hole 21 inwalls form.In operation technique, belt body 1 is penetrated in the locking head 2 around esophagus or after one week of jejunum ligation, latch 22 in the locking head 2 and ratchet 11 one-way lockings on the belt body 1 can only be tightened esophagus or jejunum, can not unclamp, and are the self-locking ligation.

In the present embodiment, said latch 22 is arranged at the side of hole 21 inwalls near belt body 1; So be provided with, as shown in Figure 3, under the ligation state, the ratchet 11 on the belt body 1 is in the ligation ring inner surface, and it tightens with esophagus or jejunum surface, makes ligation more firm, can not skid.

In the present embodiment, the free end of said belt body 1 is that thin-walled is most advanced and sophisticated; Being convenient to belt body 1 penetrates in the locking head 2.

In the present embodiment, said ligation band is the plastic tie band; Best material is chosen as the medical grade plastics that do not have rejection with human body.

Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although the preferred embodiment through with reference to this utility model is described this utility model; But those of ordinary skill in the art should be appreciated that and can make various changes to it in form with on the details, and the spirit and the scope of this utility model that does not depart from appended claims and limited.
