Problems solved by technology

The existing drainage tube is straight in one direction. After the drainage tube is placed under the dura mater, it can only face one direction. Often, the drainage tube can be moved to change the direction and re-drainage due to incomplete drainage of hematoma in other directions.
The disadvantage is that even if the direction of drainage is changed, it is difficult to completely flow out the hematoma in all directions. Changing the direction increases the chance of brain injury and infection, and the drainage tube is easy to come out of the drill hole
There is currently no suitable drainage device for subdural hematoma

Embodiment 1

[0018] Such as figure 1 with figure 2 As shown, a drainage device for subdural hematoma includes a drainage tube 3 and a connecting tube 6. One end of the drainage tube 3 and the connecting tube 6 is connected through a joint 4, and the two tubes are connected internally. The drainage tube The other end of 3 is provided with 6 forks 2-1, and the 6 forks 2-1 are arranged around the central axis of the drainage tube 3, and the 6 forks are used to place under the dura And the drainage head 2 with fixed function, the drainage head 2 is covered with a control part 1 for making it fold up, and the control part 1 is a pipe connected at both ends. It is convenient for the drainage head 2 to be inserted into the drilling hole of the skull. After the drainage head 2 is inserted into the drilling hole, the bifurcation 2-1 is spread out. This setting ensures that the drainage head 2 enters in one piece, and there is no special requirement for the size of the drilling hole in the skull. ...

Embodiment 2

[0021] Such as figure 1 with image 3 As shown, the present invention is a drainage device for subdural hematoma. The difference from Embodiment 1 is that there are three bifurcations 2-1 arranged in a ring at intervals, and the bifurcations 2-1 are arched. . Large contact surface for easy drainage.

[0022] A drainage device for subdural hematoma of the present invention, when the bifurcation 2-1 is valve-shaped, each bifurcation 2-1 can also be arranged in a ring at intervals; when the bifurcation 2-1 is arched, each The bifurcations 2-1 can also be closely adjacently arranged to form a ring.

Abstract

The invention discloses a drainage device for subdural hematoma, which comprises a drainage tube and a connecting tube. One end of the drainage tube and the connecting tube is connected through a joint, and the two tubes are connected internally. The other end of the drainage tube is provided with a There are multiple bifurcations, and multiple bifurcations are arranged around the central axis of the drainage tube. The multiple bifurcations form a drainage head that is used to place under the dura mater and play a role in drainage and fixation. The drainage head is covered with a useful The other end of the connecting tube is connected with the drainage bag for the control piece that makes it retract and release. The drainage device for subdural hematoma can drain in multiple directions, avoid dead angles, and has good fixation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a drainage device for subdural hematoma. Background technique [0002] Acute and chronic subdural hematoma is a very common disease in neurosurgery. It is necessary to drill holes and place drainage tubes to relieve the pressure of hematoma on brain tissue and treat patients. The routine drainage operation process is as follows: incision of the scalp, drilling of the skull, incision of the dura mater, placement of a drainage tube into the subdural hematoma cavity, and the other end of the drainage tube is led out from under the scalp and connected to a drainage bag. The existing drainage tube is straight in one direction. After the drainage tube is placed under the dura mater, it can only face one direction. Often, the drainage tube can be moved to change the direction and re-drainage due to incomplete drainage of hematoma in other directions. The disadvantage is that ev...
