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

[0020] 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 are connected by a joint 4, and the two tubes are communicated internally. The drainage tube There are 6 bifurcations 2-1 at the other end of 3, and 6 bifurcations 2-1 are arranged around the central axis of drainage tube 3, and the 6 bifurcations are composed for placing under the dura and for drainage The drainage head 2 has a fixed effect, and the drainage head 2 is covered with a control piece 1 for closing it, and the control piece 1 is a tube communicating at both ends. It is convenient for the drainage head 2 to be inserted into the skull drill hole. When the drainage head 2 is inserted into the drill hole, the bifurcation 2-1 is spread out. This arrangement ensures that the drainage head 2 enters in one piece, and there is no special size for the skull drill hole. Requirement...

Embodiment 2

[0023] Such as figure 1 with image 3 As shown, the present invention is a drainage device for subdural hematoma. The difference from Example 1 is that the number of bifurcations 2-1 is three, and the bifurcations 2-1 are arranged in a circular shape. . The contact surface is large for easy drainage.

[0024] The present invention is a drainage device for subdural hematoma. When the bifurcations 2-1 are petal-shaped, the bifurcations 2-1 can also be arranged in a ring at intervals; when the bifurcations 2-1 are arched, each The branches 2-1 can also be arranged in a ring shape closely adjacent to each other.

Abstract

The invention discloses a drainage device used for subdural hematoma. The drainage device comprises a drainage tube and a connection tube, one end of the drainage tube is connected with one end of the connection tube through a connector, the inside of the drainage tube is communicated with the inside of the connection tube, multiple branches are arranged at the other end of the drainage tube and are distributed around the central axis of the drainage tube, the multiple branches constitute a drainage head, the drainage head is put under the dura mater and performs the functions of drainage and fixation, the drainage head is sleeved with a control part used for enabling the drainage head to be folded and unfolded, and the other end of the connection tube is connected with a drainage bag. The drainage device used for the subdural hematoma can conduct drainage in multiple directions, head angles are prevented from being generated and the fixation is good.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and specifically relates 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 and place a drainage tube in order to relieve the pressure of the hematoma on the brain tissue and treat the patient. The conventional drainage procedure is as follows: cut the scalp, drill the skull, cut the dura, place the drainage tube into the subdural hematoma cavity, and lead the other end of the drainage tube under the scalp and connect the drainage bag. The existing drainage tube is unidirectional and straight. After the drainage tube is placed under the dura, it can only face one direction. Often, the drainage tube needs to be moved to change the direction to re-drain due to incomplete drainage of the hematoma in other directions. The disadvantage is that even if the direction of drain...
