The chronic subdural hematoma is treated by adopting a drilling and tube-placing drainage method in a conventional way, and a specific method is to drill a hole on a skull. Then the silica gel drainage tube is inserted and matched with external flushing equipment to flush the drainage hematoma, and the silica gel drainage tube is kept for 48-72h after the operation. Because the skull drill hole is small (10 mm-15 mm), the silica gel drainage tube is relatively hard and is not easy to bend at the narrow drill hole, which causes the difficulty of tube placement. The silica gel drainage tube is easy to damage cerebral cortex and arachnoid, even placed in brain to damage brain tissue.
In order to solve the above problem, a publication (bulletin) no: CN211096894U discloses a guide plate of a chronic subdural hematoma drainage tube, which is characterized in that the guide plate is inserted along a hole on a skull firstly, and the first plate body is bent towards the side wall of the skull after the first plate body is completely inserted due to an included angle between the first plate body and the second plate body, so that the first plate body can not touch and damage cerebral cortex and arachnoid. Finally, the silica gel drainage tube is inserted along the groove of the guide plate, and the insertion end of the silica gel drainage tube is also bent along the guide plate, so that the cerebral cortex and the arachnoid are prevented from being damaged.
However, the above patents still have disadvantages: because there is the contained angle between first plate body and the second plate body, the drainage tube is difficult to the crooked in contained angle department, especially under the condition that the contained angle is less than 90. In addition, the drainage tube is along the in-process of recess male, because is manual insertion, unexpected circumstances such as hand trembles, rocks probably appear, leads to the drainage tube to drop, separate from the recess, and can not insert along the recess, has the danger of touching injury cerebral cortex and arachnoid equally.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1 and 3, the present embodiment provides a guide plate 1 for an intracranial drainage tube, including a guide plate 1 having a semicircular cross section, and provided with a slide groove 2 along a central axis of the guide plate 1; the lower portion of the guide plate 1 is bent toward the slide groove 2. Specifically, the angle between the lower portion of the guide plate 1 and the guide plate 1 is greater than 90 ° and less than 170 °. The drainage tube is easy to bend for 90-170 degrees, and particularly, the difficulty of inserting the drainage tube is greatly reduced at the bending part of the guide plate 1.
As shown in fig. 2, the guide plate 1 is made of medical-grade stainless steel, and the outer surface of the guide plate 1 and the sliding groove 2 are both polished smooth, so as to reduce the frictional resistance as much as possible. The guide plate 1 is sleeved with a rubber sleeve 3 which can stretch along the axial direction of the guide plate 1, and the guide plate 1 is internally provided with a traction wire 4. The two ends of the traction wire 4 extend out of the upper end and the lower end of the guide plate 1 respectively, and the lower end of the traction wire 4 extends upwards to the lower end of the rubber sleeve 3 by bypassing the outer side of the guide plate 1. The lower extreme of the pull wire 4 that upwards extends and the lower extreme fixed connection of gum cover 3 through the upper end of dragging pull wire 4, and then makes pull wire 4 pulling gum cover 3 down extend and cover baffle 1. Further, two pull wires 4 are arranged inside the guide plate 1. The inside of baffle 1 is equipped with the through-hole 5 with two pull wires 4 one-to-one, and every pull wire 4 sliding connection is in corresponding through-hole 5. The two through holes 5 are respectively close to two ends of the guide plate 1, and the two through holes 5 are symmetrically distributed. The upper ends of the two traction wires 4 are connected, so that the two traction wires 4 are connected to form one traction wire 4. The upper ends of the two traction wires 4 are knotted, the traction wires 4 can be pulled simultaneously only by hooking the knotted positions with fingers, and the use is very convenient.
In this embodiment, the rubber sleeve 3 is made of transparent medical silica gel, has good elasticity, and can elastically deform, that is, can recover to an original state under the action of elasticity after being stretched. The upper end of the rubber sleeve 3 is fixedly connected with the outer surface of the guide plate 1, and the upper end of the rubber sleeve 3 is close to the upper end of the guide plate 1. The outer surface of the guide plate 1 is provided with a handle 6, and the handle 6 is positioned above the upper end of the rubber sleeve 3. The diameter of the guide plate 1 is small, the guide plate is inconvenient to hold, and the area of the handle 6 is large, so that the guide plate is convenient for medical staff to hold.
The specific operation of placing the drainage tube in the clinical operation process is as follows:
