The various pins 150 may be distinguished using different colors to avoid repeated injections in the same sub-tube 110.

Specifically, when the drainage tube is required to be inserted into the brain, each sub-tube 110 is moved first, so that the end of each sub-tube 110 is retracted into the tube head 140 through the guide channel 1405, and thus, the sub-tube 110 is not exposed during the insertion of the drainage tube into the brain, and the influence on brain tissue can be reduced. After the tip 140 reaches the target site, each of the sub-tubes 110 is extended to the outside of the tip 140 through the guide channel 1405, and then administration or drainage is performed.

In particular, the diameter of the intermediate tube 120 may be 1.2mm or other dimensions. The intermediate tube 120 may be fixedly connected to the outer sleeve 130 by welding or the like. Each intermediate tube 120 is aligned with a guide channel 1405 of a corresponding tube head 140.

In one embodiment, as shown in fig. 3 and 4, the guide channel 1405 is arcuate. The outlet 1404 and inlet 1403 of guide channel 1405 are not in line so that each of the sub-tubes 110 may be guided to extend from tube head 140 in different directions.

In one embodiment, the number of the sub-tubes 110 is 3, the number of the intermediate tubes 120 is 3, the material used for the sub-tubes 110 is PTFE, and the material used for the tube head 140 and the outer sleeve 130 is 304 stainless steel.

That is, after the ends of the sub-tubes 110 are protruded from the corresponding guide channels 1405, the ends of the sub-tubes 110 are separated from each other, and an angle of 130 degrees is formed between the end of the sub-tube 110 located outside the tube head 140 and the axis of the outer sleeve 130. Since 3 sub-tubes 110,3 are provided, the sub-tubes 110 are separated from each other and are all at an angle of 130 degrees to the axis of the outer sleeve 130, and at the same time, the outlets 1404 of the respective guide channels 1405 are uniformly distributed along the circumferential direction of the tube head 140. This facilitates drug infusion and drainage over as large a range as possible.

It can be appreciated that the above angles can also be set according to the actual situation, so as to meet the drainage requirement of the hematoma area in the brain.

In one embodiment, one end of the middle tube 120 is located outside the outer tube 130 and is bent outwards, one end of each sub-tube 110, which is far away from the tube head 140, is separated from the other end, and the tail end of the outer tube 130 is closed by a silica gel plug. This facilitates the provision of associated auxiliary equipment for each sub-tube 110 and thus the operation of each auxiliary equipment. It is also advantageous to move each sub-pipe 110 so that each sub-pipe 110 does not interfere with each other.

In one embodiment, the tube head 140 includes a tapered portion 1402 and a cylindrical portion 1401, the guide channel 1405 is disposed on the cylindrical portion 1401, the outlet 1404 of the guide channel 1405 is disposed on the outer wall of the outlet 1404 of the guide channel 1405, and the inlet 1403 of the guide channel 1405 is disposed on the end face of the cylindrical portion 1401.

The elastic sleeve is used for locking the sub-tube 110 by deformation after being pressed by the screw 170.

In one embodiment, the elastic sleeve is a silicone sleeve 180, and a handle 190 is disposed at one end of the screw 170.

Specifically, by rotating the screw 170, the screw 170 applies pressure to the silicone sleeve 180, and since one end of the silicone sleeve 180 abuts against the middle tube 120, the silicone sleeve 180 deforms under the action of the pressure, after the silicone sleeve 180 deforms, the inner hole of the silicone sleeve 180 deforms, and the deformed silicone sleeve 180 applies pressure to the sub-tube 110, so that the sub-tube 110 is locked. Reverse rotation of the screw 170 causes the silicone sleeve 180 to reset and the sub-tube 110 to move freely.

In one embodiment, the end of the sub-tube 110 near the end of the tube head 140 is a blind end, and a plurality of through holes 1101 are provided on the side wall of the sub-tube 110 near the end of the tube head 140.

The method of using the drainage tube of the present application is described in detail below.

2. Measuring the hematoma radius on the navigation device, and setting the length of the extension tube head 140 of the sub-tube 110 according to the hematoma radius;

3. After the extension of the sub-pipe 110 from the pipe head 140 reaches a preset length, the screw 170 is rotated to fix the position of the sub-pipe 110;

4. connecting the syringe with the sucked medicine with the pintle 150 at the tail end of the sub-tube 110, and injecting the medicine;

5. Drug is injected through each of the three sub-tubes 110, and then the screw 170 is rotated to retract the sub-tubes 110 within the guide channel 1405 of the tube head 140;

6. Under the guidance of navigation equipment, the drainage tube is rotated or moved according to the need (according to the size and shape of hematoma), so that the drainage tube is moved to different positions of hematoma areas, and then the medicine injection step is repeated;

7. after the injection is finished, drainage operation can be performed.

According to the application, under the guidance of the navigation equipment, the hematoma dissolving point is increased through a plurality of medicine injection channels, so that the problem of low hematoma dissolving speed caused by a single hematoma dissolving point formed by a traditional single medicine injection channel is avoided, and the operation that the hematoma dissolving is carried out by intermittent medicine injection after an operation is avoided. The application accelerates the dissolution speed of hematoma, thereby accelerating the drainage and discharge speed after the dissolution of hematoma, further rapidly removing the compression of hematoma on the drug injection functional structure, reducing the harm caused by hypertensive cerebral hemorrhage diseases, reducing the risk of intracranial infection caused by intermittent drug injection after operation, reducing the drug use amount and lowering the drug expense of patients.
