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...
