The drainage tube body 10 includes an adjustment end and an insertion end; the adjustment end is provided with at least two tearing cuts, and the tearing cuts are parallel to the axial direction of the drainage tube body 10.

[0032] The beneficial effects of this embodiment are as follows: by providing the drainage tube body 10 with an adjustment end and an insertion end, since the adjustment end can be torn open, the length of the drainage tube body 10 can be adjusted through the adjustment end, and the length of the drainage tube body 10 is convenient to adjust; at least two tearing cuts are provided, which is convenient for manually holding and tearing the adjustment end of the drainage tube body 10; since the tearing cut is parallel to the axial direction of the drainage tube body 10, when the adjustment end of the drainage tube body 10 is torn open by the tearing cut, the overlap of the extension position of the subsequent tearing of the tearing cut can be reduced, which is conducive to the successful adjustment of the length of the drainage tube body 10; when in use, the axial length of the adjustment end is adjusted according to the length of the guide rod 30, the guide rod 30 enters the drainage tube body 10 along the adjustment end, and continues to penetrate the drainage tube body 10 until the guide rod 30 extends into the insertion end, so that the drainage tube body 10 can be driven by the guide rod 30 to accurately reach the position where drainage is required, so as to accurately control the depth and position of the insertion end and improve the accuracy of the placement of the drainage tube body 10.

[0033] Preferably, in the embodiments, see Figures 1 to 3 At least two tearing cuts divide the adjustment end into at least two tearing parts 11 along the axial direction, and an auxiliary head 12 is connected to the end of each tearing part 11.

[0034] The beneficial effect of adopting the preferred solution in the above embodiment is that each tearing portion 11 is individually connected to an auxiliary head 12, which is convenient for operators to hold and facilitates manual tearing and growth of the tearing incision.

[0035] During specific use, the auxiliary head 12 is columnar, and the outer wall of the auxiliary head 12 may be provided with a threaded anti-slip structure or a step structure to facilitate the holding of the auxiliary head 12 and assist in tearing open the drainage tube body 10 .

[0036] Preferably, in the embodiment, the auxiliary head 12 presses the tearing portion 11 by means of a threaded structure or a clamping structure.

[0037] The beneficial effect of adopting the preferred scheme in the above embodiment is that the threaded structure clamps the tearing part 11, which is convenient for disassembly and adjustment. When the length of the tearing part 11 is too long, the auxiliary head 12 can be removed and the length of the tearing part 11 can be manually shortened, and then the auxiliary head 12 can be reinstalled, thereby facilitating the auxiliary head 12 to be stressed and used correctly during tearing; the clamping structure can simplify the disassembly method, and the tearing part 11 can be fixed by deforming the auxiliary head 12 or setting a special clamping position, thereby facilitating the disassembly and adjustment of the tearing part 11.

[0038] On the basis of the above scheme, the thread structure can be a double-layer thread structure, and the auxiliary head 12 can have two layers of separable columnar clamping parts, which have internal and external threads respectively. By extending the tearing part 11 between the two clamping parts and then tightening the two clamping parts, the tearing part 11 is pressed, which has good stability and high reliability. When the clamping structure is set to press the tearing part 11, it can be set as a double-layer clamping structure, that is, the auxiliary head 12 includes at least two detachable workpieces, and the two workpieces are clamped and fixed in position. During installation, the tearing part 11 is located between the clamping fitting surfaces of the two workpieces, and then the two workpieces are clamped, thereby pressing the tearing part 11, that is, fixing the tearing part 11 and the auxiliary head 12; a single-layer clamping structure can also be set, and the auxiliary head 12 is only one workpiece. By setting a clamping position on the auxiliary head 12, the tearing part 11 is wrapped or clamped on the clamping position during installation, thereby fixing the tearing part 11 and the auxiliary head 12.

[0039] Preferably, in the embodiments, see Figures 1 to 3 The tearing cuts are evenly arranged along the circumferential direction.

[0040] The beneficial effect of adopting the preferred solution in the above embodiment is that the tearing cuts are evenly arranged, which facilitates uniform force during tearing, reduces the probability of overlapping of the extended positions of the tearing cuts during tearing, and improves the stability of the drainage tube body 10 when adjusting its length.

[0041] Preferably, in the embodiments, see Figure 3 , Figure 4 , and also includes a Luer connector 20, which is plugged and connected to the drainage tube body 10 along the adjustment end.

[0042] The beneficial effect of adopting the preferred solution in the above embodiment is that the Luer connector 20 is provided to facilitate the connection of the drainage tube body 10 with other pipes, improve the stability of the connection, and thus facilitate the subsequent connection of the drainage tube or the collection of drainage fluid.

[0043] As a parallel technical solution of the above-mentioned solution, when the Luer connector 20 is not provided, the drainage tube body 10 can also be directly connected to the subsequent pipeline, or can also directly collect the drainage fluid, etc., which can be selected according to the application scenario.

[0044] Preferably, in the embodiments, see Figure 3 , Figure 4 The Luer connector 20 includes a clamping tube 21 and a clamping groove 22. The clamping tube 21 is located at one end of the Luer connector 20 and is used to be inserted into the drainage tube body 10. The clamping groove 22 is an annular concave structure surrounding the outer circumference of the clamping tube 21. The clamping groove 22 is used to clamp with the adjustment end.

[0045] The beneficial effect of adopting the preferred scheme in the above embodiment is that a clamping tube 21 and a clamping groove 22 are provided on the Luer connector 20, wherein the clamping tube 21 is used to be inserted into the drainage tube body 10 and play the effect of draining out the drainage fluid, and the clamping groove 22 is arranged around the clamping tube 21, and is used to clamp the adjustment end, so that the Luer connector 20 is tightly connected with the adjustment end and guides the fluid; when installing the Luer connector 20, firstly, all the parts with the tearing cut are folded toward the insertion end of the drainage tube body 10, so that the position where the clamping tube 21 is clamped into the drainage tube body 10 is a complete pipe without a cut, and then the drainage tube body 10 is gradually pressed into the clamping groove 22, and the drainage tube body 10 is preferably pressed into the groove bottom of the clamping groove 22. After the Luer connector 20 and the drainage tube body 10 are clamped, the operation is completed. At this time, the structure of the groove bottom pressed into the clamping groove 22 is a double-layer part of the drainage tube body 10, one layer is a pipe without a cut, and the other layer is a pipe with a tearing cut.

[0046] On the basis of the above technical solution, the outer ring of the open end of the snap-in groove 22 has a taper to facilitate the snap-in of the adjustment end.
