The first embodiment is as follows:
the present invention will be described in detail with reference to the accompanying drawings 1-4, and specifically, the structure is as follows:
the embodiment provides a guide tube for laparoscopic sleeve gastrectomy, which comprises a guide head 1, a guide tube main body, a three-channel joint 5 and a balloon 2, wherein one end of the guide tube main body is fixed with the guide head 1, the other end of the guide tube main body is connected with the three-channel joint 5, and the three-channel joint 5 is used for connecting an external instrument. The air bag 2 is fixed on the circumferential outer side of the guiding tube body, and the inflated air bag 2 can enable the guiding tube to be stably clamped on the inner side of the pylorus.
As shown in fig. 1, a check valve 6 is installed in a passage where the three-way joint 5 is connected to the inflation passage 8 to prevent gas inside the airbag 2 from leaking reversely. As shown in fig. 2, the surface of the guiding tube body is marked with a scale for measuring the length of the guiding tube extending into the body and preventing the excessive length from damaging the organ.
The whole body of the guide tube body is cylindrical, three channels, namely an inflation channel 8, a sickle-shaped channel 7 and a extravasated blood absorption channel 3, are separated from the inside of the guide tube body along the axial direction, wherein the inflation channel 8 and the extravasated blood absorption channel 3 are respectively arranged on two sides of the sickle-shaped channel 7, and the axial lines of the inflation channel 8 and the extravasated blood absorption channel 3 are parallel to the axial line of the sickle-shaped channel 7.
The extravasated blood absorption channel 3 is used for discharging liquid in the alimentary canal during the operation; a plurality of liquid suction holes 4 are formed in the side, corresponding to the extravasated blood absorption channel 3, of the guide tube main body at intervals, and liquid in the alimentary canal is sucked into the extravasated blood absorption channel through the liquid suction holes 4 and then discharged. The number of the liquid suction holes 4 is selected according to the actual operation requirement.
The inflation channel 8 is used for inflating the air sac 2 which penetrates through the pylorus and extends into the outer side of the guiding tube in the duodenum in the operation process. The air bag 2 is fixed at one end of the guiding tube main body close to the guiding head 1, a vent hole 9 for communicating the interior of the air bag 2 with the inflation channel 8 is formed in the side surface of the guiding tube main body, and gas can enter the air bag 2 from the inflation channel 8 through the vent hole 9 to inflate the air bag; thereby the guiding tube is blocked in the pylorus, and the pylorus is prevented from being damaged by the back and forth movement of the guiding tube at the pylorus opening.
In this embodiment, the balloon 2 is fixed outside the guiding tube body by adhesive and surrounds the guiding tube body by one circle, so as to ensure that the guiding tube can be stably clamped inside the pylorus during operation. It can be understood that the balloon 2 may be fixed to the guiding tube body in other ways as long as the tight connection between the two is ensured.
The sickle-shaped channel 7 is used for exhausting gas in the alimentary canal in the operation process; as shown in fig. 3, the cross section of the sickle-shaped channel 7 is a central symmetrical structure, the upper side (with the direction shown in fig. 3 as a reference) of the sickle-shaped channel 7 has a curvature curved toward the aeration channel 8, and the lower side has a curvature curved toward the sludge absorption channel 3; the arc length of the lower side arc is longer than that of the upper side arc; the left side and the right side are radians which keep the same direction with the guiding tube main body. The sickle-shaped channel 7 of the embodiment can ensure even and stable discharge of gas through four circular arcs and can ensure the discharge efficiency.
In the present embodiment, as shown in FIG. 3, both the aeration channel 8 and the sludge absorbing channel 3 are channels having a circular cross section, and the diameter of the sludge absorbing channel 3 is larger than that of the aeration channel 8. This is due to the large concentration of fluid in the digestive tract, which requires a larger diameter passage to ensure its smooth discharge. The gas filled in the inflation channel 8 only needs to be enough to enable the air bag 2 to be expanded, and the diameter is not required to be too large. The radian of the upper side of the sickle-shaped channel 7 can be reduced through the inflation channel 8 with a smaller diameter so as to ensure the maximum area of the sickle-shaped channel 7.
When laparoscopic sleeve gastrectomy is performed, the guide tube of the present embodiment is inserted into the digestive tract and inserted into the duodenum through the pylorus, and the insertion length of the guide tube is obtained by observing the scale 10, so that the guide tube is positioned at a desired specific position in the digestive tract; and the air bag 2 at the tail end of the guide head 1 is inflated to bulge to form initial positioning, so that the pylorus is prevented from being damaged by the back and forth movement of the guide tube extending into the pylorus. At this time, the check valve 6 works to prevent gas from leaking reversely. Then, the position is used as a cutting reference line of a surgical instrument to carry out laparoscopic sleeve gastrectomy. At the same time of operation, the liquid and the extravasated blood in the alimentary canal are sucked into the extravasated blood absorption channel 3 from the liquid suction hole 4 on the side wall of the guide tube and are discharged out of the body through the suction device.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
