Embodiment 1

[0047] This embodiment provides a drainage catheter, referring to Figure 1 to Figure 6 , the drainage catheter includes a distal flexible pipe 1, a proximal connecting pipe 2 and a pipe joint 3; Silk channel 200. The proximal end of the distal hose 1 is connected to the distal end of the proximal connecting pipe 2 through the pipe joint 3, and the proximal end of the liquid passage 100 of the distal hose 1 is docked with the distal end of the liquid passage 100 of the pipe joint 3 , the distal end of the liquid passage 100 of the proximal connecting tube 2 is docked with the proximal end of the liquid passage 100 of the pipe joint 3; The distal end of the proximal connecting tube 2 is docked one by one with the proximal end of the steering wire channel 200 of the pipe joint 3 .

[0048] In the drainage catheter provided in this embodiment, the connection between the distal flexible tube 1 and the proximal connecting tube 2 is realized through the tube joint 3, and through t...

Embodiment 2

[0058] This embodiment provides a drainage catheter. The structure of the drainage catheter is obtained in combination with Embodiment 1, and on the basis of the drainage catheter provided in Embodiment 1, further, the distal hose 1, the pipe joint 3 and the proximal connection Among the three tubes 2, at least one is also provided with a camera wiring channel 300 .

[0059] The drainage catheter provided in this embodiment can be used in conjunction with the camera module, so that the distal end of the drainage catheter has a monitoring function, so that the doctor can monitor the lavage and suction of subdural hematoma fluid in real time during the operation, which is beneficial to The hematoma fluid was completely removed, reducing the risk of secondary surgery.

[0060] Preferably, but not limited to, the far-end flexible pipe 1, the pipe joint 3 and the proximal connecting pipe 2 are all provided with a camera routing channel 300; The far end of the camera routing channe...

Embodiment 3

[0064] This embodiment provides a kind of lavage drainage device, refer to Figure 7 and Figure 8 , combined with Figure 1 to Figure 6 , the irrigation and drainage device includes at least one steering wire 5 and the drainage catheter provided in any optional implementation manner in the first embodiment. Specifically, the steering wire 5 passes through the steering wire channel 200 of the distal hose 1, the steering wire channel 200 of the pipe joint 3 and the steering wire channel 200 of the proximal connecting tube 2 from the distal end to the proximal end, and the steering wire 5 The distal end of the distal end is connected to the distal end of the distal hose 1; the steering wire 5 can pull the distal end of the distal hose 1 to drive the distal hose 1 under the condition of being pulled toward the proximal end. The distal bend turns.

[0065] The functional effects that can be achieved by the irrigation and drainage device provided in this embodiment can be obtain...

Abstract

The invention provides a drainage catheter and a lavage drainage device, and relates to the field of medical instruments, wherein the drainage catheter comprises a far-end hose, a near-end connecting pipe and a pipe connector; the far-end hose, the near-end connecting pipe and the pipe connector are respectively provided with a liquid passing channel and at least one steering wire channel; the near end of the far-end hose is connected with the far end of the near-end connecting pipe through the pipe connector, the near end of the liquid passing channel of the far-end hose is in butt joint with the far end of the liquid passing channel of the pipe connector, and the far end of the liquid passing channel of the near-end connecting pipe is in butt joint with the near end of the liquid passing channel of the pipe connector; the near ends of the steering wire channels of the far-end hose are in one-to-one butt joint with the far ends of the steering wire channels of the pipe connector; and the far ends of the steering wire channels of the near-end connecting pipe are in one-to-one butt joint with the near ends of the steering wire channels of the pipe connector. The problem that hematoma liquid cannot be thoroughly removed due to the fact that a doctor cannot adjust the position of a suction opening of a silicone pipe in an existing lavage drainage technology is at least solved, and then the risk of a secondary operation is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a drainage catheter and a lavage drainage device. Background technique [0002] Clinically, chronic subdural hematoma refers to those with intracranial hemorrhage occurring in the subdural space more than three weeks after injury. After the hematoma increases, it will produce a mass effect, resulting in pressure on the ventricles and brainstem, resulting in vomiting, disturbance of consciousness, and headache. , mainly increased intracranial pressure, CT diagnosis and decisive surgical intervention should be performed in time. At present, the main treatment method is the closed drainage of skull drilling. The doctor opens a hole in the corresponding skull position of the patient, inserts the silicone drainage tube into the subdural intracranial, and repeatedly lavages and drains the hematoma fluid until the aspiration fluid is clear. to clear the hematoma. [0003] ...
