[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clear and understandable, this application is further described in detail. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0033] In one embodiment, a cranial drainage device includes a drainage catheter 1, a core guide system 3 is provided in the drainage catheter 1, and an endoscope system 2 is provided in the core guide system 3; the drainage catheter 1 includes a drainage cavity 13, an imaging component is provided at one end of the drainage cavity 13, and side holes 12 are provided on both sides of the drainage cavity 13; the core guide system 3 includes a metal tube 31, and the surface of the metal tube 31 is coated with a hydrophilic coating; the endoscope system includes an electric wire 22, an endoscope 21 is provided at one end of the electric wire 22, a circuit board 23 is provided at the other end of the electric wire 22, and an interface 231 is provided on the circuit board 23; an adhesive film 311 is provided at one end of the metal tube 31, and the adhesive film 311 is on the same side as the imaging component; the electric wire 22 and the endoscope 21 are provided in the metal tube 31; a handle 32 is provided at the other end of the metal tube 31; the cranial drainage device also includes a cranial drainage display screen 4, a computer interface 5 is provided on the cranial drainage display screen 4, and the computer interface 5 cooperates with the interface 231.

[0034] Specifically, the drainage catheter 1 is made of silicone, the imaging component end needs to be inserted into the skull, and the other end is connected to the Luer connector outside the skull; the imaging component includes a plugging hole 11, which is a cube and made of silicone. The plugging hole 11 is mirror-transparent as a whole, with a width of 3-5mm and a transmittance greater than 80%; the plugging hole 11 on the side away from the drainage cavity 13 is a plugging plane 111, and the plugging plane 111 adopts a relatively flat structure to ensure transmittance and imaging effect. The end point of the plugging hole 11 is provided with a rounded corner 121, which can reduce the damage to the skull when the drainage catheter 1 enters the skull; the side hole 12 is used for drainage after the operation is completed to remove hematoma and water accumulation. The drainage cavity 13 is used to insert the guide core system 3 into the drainage cavity 13 and pull it out from the drainage cavity 13 after completion, without the need to open a separate cavity for the endoscope system 3; the drainage cavity 13 can be designed as a single cavity or multiple cavities, or a cavity can be used for dual purposes, that is, it can be used for extracranial drainage and visual system channels during surgery;

[0035] The endoscope 21 penetrates the brain to perform imaging and transmits the brain visual field to the brain drainage display screen 4 via the wire 22, facilitating real-time monitoring of the surgical field of view. The wire 22 is electrically connected to the computer interface 5 via the interface 231 provided on the circuit board 23, which can be configured as a Type-C interface. The brain drainage display screen 4 is equipped with a professional brain drainage control system and a visual system, which provide real-time feedback to the brain drainage display screen 4, allowing the drainage catheter 1 to be inserted into the designated position and accurately injected into the bleeding point.

[0036] The metal tube 31 needs to be smaller than the drainage catheter 1 to facilitate the insertion of the metal tube 31 into the drainage catheter 1; the endoscope 21 and the wires 22 are hidden in the metal tube 31, and the adhesive film 311 at the front end of the metal tube 31 can form a protective film, which can ensure imaging and also ensure that the endoscope 21 does not come into contact with blood and brain tissue. The adhesive material is insulating to ensure that no leakage occurs; the endoscope 21 can observe the brain tissue through the adhesive film 311 and the plugging hole 11 of the drainage catheter 1, and display it on the cranial drainage display screen 4 through data transmission; during drainage surgery, the drainage tube usually needs to be guided to the correct position using a guide needle; the metal tube 31 can support the inner cavity of the soft drainage catheter 1 to prevent the soft drainage catheter 1 from being broken by resistance after being inserted into the brain due to being too soft. The metal tube 31 can replace the guide needle in drainage surgery;

[0037] The surface of the metal tube 31 is coated with a hydrophilic coating, which can play an anti-coagulant and lubricating role and reduce inflammation; reduce the adsorption of platelets and fibrin to prevent coagulation; increase the lubrication effect to prevent the metal tube 31 from being difficult to withdraw after the operation is completed, reduce the occurrence of inflammation on the hands during the process, reduce the risk of infection, and protect the brain; the handle 32 is set at the end away from the endoscope 21 and is used to hold the drainage device.

[0038] During the cranial drainage operation, the image transmitted on the cranial drainage display screen 4 is used to observe and determine whether the drainage catheter 1 is inserted into the required position during the operation, and then drainage is performed. After the operation is completed, the core guide system 3 and the endoscope system 2 are pulled out from the drainage catheter 1 together, and then subsequent cranial drainage treatment is performed. After the treatment is completed, the consumables are destroyed.

[0039] The present application provides a cranial drainage device, comprising a drainage catheter, a core guide system provided in the drainage catheter, and an endoscope system provided in the core guide system; the drainage catheter comprises a drainage cavity, an imaging component is provided at one end of the drainage cavity, and side holes are provided on both sides of the drainage cavity; the core guide system comprises a metal tube, and the surface of the metal tube is coated with a hydrophilic coating; the drainage catheter of the present application is made of thermoelastic material and is disposable. By adding a highly transmittance plugging hole and providing rounded corners on the plugging hole, the imaging effect can be guaranteed and damage to brain tissue can be prevented; the drainage catheter can be designed as a single cavity or multiple cavities, or a single cavity can be used for two purposes; the core guide system is hydrophilically treated to play an anti-coagulant, lubricating and inflammation-reducing role; the core guide system can be used to replace the surgical drainage guide needle and is more convenient to use; the visual system and the professional cranial drainage control system are used to accurately insert the drainage catheter into the bleeding point; the cranial drainage device has a simple structural design, a clear field of view, good cranial and brain protection effect, and is safe and effective.
