Problems solved by technology

[0004] When the peripheral tissues of the inner opening of the sinus tract show fibrosis, the effect of using the above-mentioned therapeutic device combined with the negative pressure of the digestive endoscope will be greatly reduced. Most of the time, it is difficult to inhale the inner opening of the sinus tract and its surrounding tissues into the end port of the cannula. And then affect the effect of the final ligation, need to be improved urgently

Embodiment 1

[0042] see figure 2, the present embodiment specifically provides a sleeve for sealing the inner opening of the sinus tract, including a sleeve body, the sleeve is a straight tube and its end port is a straight mouth, and the inner wall of the sleeve 2 is provided with a support portion 4, so The support part 4 is provided with a hollow cylindrical spacer 5 and the spacer 5 is provided with a hook 5, one end of the hook 5 is connected with a push-pull rod 6, along with the push-pull rod 6 along the axial direction of the casing 2 Move, the hook 5 can move relative to the limit sleeve 5 .

[0043] The cannula is used to install components such as the ligation device; second, its free port can be used to delineate the inner opening of the sinus tract, so that the operator can use the ligation device to seal the inner opening of the sinus tract after triggering the excitation wire.

[0044] The supporting part is the basic component in the present invention, and is used for fix...

Embodiment 2

[0050] see image 3 , the present embodiment specifically provides a sleeve for sealing the inner opening of the sinus tract, including a sleeve body, the sleeve is a straight tube and its end port is a bell mouth, and the inner wall of the sleeve 2 is provided with a support portion 4, so The support part 4 is provided with a hollow cylindrical spacer 5 and the spacer 5 is provided with a hook 5, one end of the hook 5 is connected with a push-pull rod 6, along with the push-pull rod 6 along the axial direction of the casing 2 Move, the hook 5 can move relative to the limit sleeve 5 .

[0051] The usage mode of this embodiment is the same as above.

[0052] In actual operation, even if the internal opening of the sinus tract is located outside the intestinal folds or in front of the gastric folds, however, in view of the different diameters of the internal openings of the sinus tracts, in order to adapt to the internal openings of the sinus tracts with different diameters, th...

Embodiment 3

[0054] see Figure 4 , the present embodiment specifically provides a sleeve for sealing the inner opening of the sinus tract, including a sleeve body, the sleeve is an elbow and its end port is straight, and the inner wall of the sleeve 2 is provided with a support portion 4, so The support part 4 is provided with a hollow cylindrical spacer 5 and the spacer 5 is provided with a hook 5, one end of the hook 5 is connected with a push-pull rod 6, along with the push-pull rod 6 along the axial direction of the casing 2 Move, the hook 5 can move relative to the limit sleeve 5 .

[0055] The usage mode of this embodiment is the same as above.

[0056] In actual operation, since the inner opening of the sinus tract may be located on the inner side of the intestinal folds or the backside of the gastric folds, when the end of the cannula enters the inner side of the intestinal folds or the backside of the gastric folds to search for the inner opening of the sinus tract, if the cannu...

Abstract

When the peripheral tissue of the inner opening of the sinus tract forms fibrosis, the effect of negative pressure is greatly reduced when the existing treatment device is combined with a gastrointestinal endoscopy, in order to solve the technical problems existing in the prior art, the invention provides a cannula used for closing the inner opening of the sinus tract and a treatment device used for closing the inner opening of the sinus tract, which can bring the inner opening of the sinus tract and part of the tissue around the inner opening of the sinus tract into the end opening of the tail end of the cannula when the peripheral tissue of the inner opening of the sinus tract forms fibrosis.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a cannula for sealing the inner opening of the sinus tract, and also relates to a therapeutic device for sealing the inner opening of the sinus tract. Background technique [0002] At present, when treating the internal opening of the sinus tract in clinical practice, a professional therapeutic device for sealing the internal opening of the sinus tract can be used. The therapeutic device includes: a digestive endoscope, a sleeve connected to the end of the digestive endoscope and a set A ligation device on the outer wall of the cannula tip. like figure 1 shown. [0003] The working principle of the existing therapeutic device is as follows: after the operator uses a digestive endoscope to observe the internal opening of the sinus tract in the digestive tract, the end of the cannula is masked to cover the internal opening of the sinus tract, and then the negative pres...
