Example 1:
referring to fig. 1 to 4, the embodiment of the utility model discloses a bile duct internal fixation anti-slipping PTCD drainage tube 10 with an air bag, which comprises a main tube 110, a first air bag 120 and an inflation tube 130, wherein the first air bag 120 is installed on the outer side wall of the main tube 110, and the distance between the first air bag 120 and the end part of the main tube 110 is 2 cm-4 cm, so as to meet the requirements of different people; inflation tube 130 is in communication with first bladder 120.
The fixed anti-slipping PTCD drainage tube with balloon in bile duct 10 disclosed in the present embodiment is provided with a first balloon 120 and an inflation tube 130 for allowing gas to flow into the first balloon 120 on the outer wall of the main tube 110. Initially, the first balloon 120 is not inflated, the first balloon 120 is attached to the outer sidewall of the main tube 110, and the main tube 110 can be smoothly inserted into the bile duct 20 with the first balloon 120. After the main tube 110 is inserted into the bile duct 20, the first balloon 120 is inflated through the inflation tube 130, the first balloon 120 is inflated and then expands, the expanded first balloon 120 is larger than the opening on the bile duct 20, at this time, the inner fixation of the main tube 110 and the bile duct 20 is formed, the main tube 110 is prevented from falling off from the bile duct 20, and therefore the effective drainage of the PTD tube is ensured. Before the primary tube is withdrawn, the gas in the first balloon 120 is exhausted, at which time the primary tube 110 may be withdrawn from the bile duct 20.
In this embodiment, an inflation channel 111 may be formed on a side wall of the main tube 110, one end of the inflation channel 111 is communicated with the first air bag 120, and the other end of the inflation channel 111 is communicated with the inflation tube 130. A one-way control valve is installed on the inflation tube 130, and the one-way control valve is located on the inflation device and the inflation tube 130. The inflation device inflates the first air bag 120 through the inflation tube 130, then the inflation tube 130 can be directly disconnected from the inflation device, the first air bag 120 cannot deflate under the limitation of the one-way control valve, and the gas in the first air bag 120 is discharged before the main tube is pulled out.
Of course, the opening of the inflation channel 111 on the side wall of the main tube 110 is only one embodiment of this embodiment, and in other embodiments, the inflation tube 130 is inserted into the main tube 110, and then the inflation tube 130 penetrates through the side wall of the main tube 110 and then is communicated with the first air bag 120 on the outer wall. However, the inflation channel 111 is formed on the side wall of the main pipe 110 to prevent the side wall of the main pipe 110 from being damaged in a penetrating manner, thereby ensuring the sealing performance of the main pipe 110.
Further, a first groove 112 may be further provided on an outer wall of the main tube body 110. The first groove 112 communicates with the inflation passage 111, and the first airbag 120 is installed in the first groove 112. This prevents the first balloon 120 from protruding the outer surface of the main tube 110, thereby ensuring smooth entrance and exit of the main tube 110 into and out of the bile duct 20.
In this case, the first bladder 120 may be a film having elasticity, and the periphery of the film is a connecting edge. The first airbag 120 is connected to the sidewall of the first groove 112 by the connecting edge, and the first airbag 120 is located at the notch of the first groove 112. Such that first bladder 120 is substantially flush with the outer wall of main tube 110 or slightly recessed into first groove 112 when gas is not being passed into first groove 112. At this time, when the main tube body 110 is placed, the side wall of the opening of the bile duct 20 can slide along the surface of the first balloon 120, so as to avoid forming a protruding structure on the surface of the main tube body 110, thereby effectively avoiding causing additional side damage to the puncture channel and the bile duct 20. Of course, the first air bag 120 having a film shape is only one embodiment of the present embodiment, and in other embodiments, the first air bag 120 may have a spherical shape or other shape that can substantially fill the first groove 112 after air suction.
In order to make the connection of the main tube 110 and the bile duct 20 more stable, the first groove 112 and the first balloon 120 may be provided in a ring shape. Thus, after the first balloon 120 is inflated, the first balloon 120 contacts the inner wall of the bile duct 20 more completely and uniformly, and the main tube 110 can be prevented from being deviated. In other embodiments, the first groove 112 is not provided in a ring shape, but the first groove 112 and the first balloon 120 are provided in a plurality, and the plurality of first grooves 112 and the plurality of first balloons 120 are uniformly provided along the circumference of the main tube 110, so that the main tube 110 and the bile duct 20 can be stably connected.
The main tubular body 110 is chamfered at an end thereof so that the main tubular body 110 can be rapidly inserted into an opening in the bile duct 20 when the main tubular body 110 is inserted into the bile duct 20. The wall of the main tube 110 is graduated, and when the main tube 110 is inserted into the tube, the insertion depth of the main tube 110 can be determined by the graduation. A side wall hole is further provided at an end of the main pipe body 110, and the side wall hole penetrates a side wall of the main pipe body 110 along the proceeding of the main pipe body 110. The arrangement of the side wall holes is mainly used for increasing the drainage efficiency. The side wall hole may be provided in plural in the axial direction of the main tube 110. The distance between two adjacent side wall holes in the axial direction of the main tube body 110 is set to be about 2 mm.
Further, a positioning block 140 for universal positioning may be provided on an outer wall of the main tube body 110. The positioning block 140 is detachably connected to the main tube 110. When puncturing, the main tube body 110 is inserted into a proper depth, then the positioning block 140 is mounted on the main tube body 110, after the positioning block 140 is abutted against the abdominal wall 30, the main tube body 110 can be limited, the main tube body 110 is prevented from further extending into the bile duct 20, and at the moment, the first air bag 120 just completely enters the bile duct 20. After the first air bag 120 is inflated, the first air bag 120 and the positioning block 140 can limit two directions of the main pipe body 110, so as to ensure that the main pipe body 110 is in good position.
Example 2:
referring to fig. 5 to 7, the embodiment also discloses an anti-slipping PTCD drainage tube 10 fixed in a bile duct with a balloon, the technical solution described in embodiment 1 is also applicable to the embodiment, and the technical solution disclosed in embodiment 1 is not described again.
Specifically, the present embodiment is different from embodiment 1 in that the fixed anti-slipping PTCD drainage tube with balloon 10 in the bile duct disclosed in the present embodiment further includes a second balloon 150.
Meanwhile, a second groove 113 is also formed in the outer wall of the main tube 110, the second groove 113 and the first groove 112 are axially spaced from each other along the main tube 110, the second groove 113 is not communicated with the inflation channel 111, and the second airbag 150 is located in the second groove 113. in this embodiment, a second inflation tube for independently supplying air to the second airbag 150 is additionally provided, and the second inflation tube may be located in the main tube 110 or attached to the inner wall of the main tube 110, or another inflation channel for inflating the second airbag 150 is directly formed in the side wall of the main tube 110.
With the second groove 113 and the second balloon 150 in the present embodiment, the structure and shape thereof may be the same as those of the first groove 112 and the first balloon 120.
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.
