Novel drainage device for neurosurgical operation

Abstract

The invention discloses a novel drainage device for neurosurgical operation, wherein the drainage device comprises a speed regulating device and a sealing device. According to the drainage device forneurosurgical operation, by adjusting mutual meshed combination of a big gear and a small gear, the drainage speed of paddle blades can be changed, and the drainage speed and pressure can be rapidly adjusted, the drainage speed and pressure of the drainage device can be quickly adjusted, and the use safety of the drainage device is increased. Through arrangement of the sealing device inside a tankbody, when the drainage device is not used, a sealing plate can be clamped on the upper end of an air suction pipe, so that the air suction pipe is in a sealed state, and then dust is blocked. Duringdrainage, a connecting block is pulled to the right end to move to the right end via a connecting rod mechanism, a push rod drives the sealing plate to release the sealing state of the air suction pipe, and the air suction pipe can work normally. The advantages of keeping the sealing state inside the air suction pipe when the drainage device is not used and no dust sticking inside the air suctionpipe are achieved.

Description

technical field [0001] The invention relates to the related field of neurosurgery, in particular to a novel drainage device for neurosurgery. Background technique [0002] At present, in the clinical treatment of many diseases in neurosurgery, such as the treatment of brain tumors, severe intracranial injuries, and hypertensive cerebral hemorrhage, neurosurgical drainage devices are required; There are abundant blood vessels, which require multi-level separation, and there will be more bleeding, which requires drainage of the oozing blood and other waste fluid after the operation. During the drainage process, due to the difference in the amount of bleeding, the existing neurosurgery Surgical drainage devices have the following problems: [0003] 1. It is not easy to quickly adjust the drainage speed and pressure of the drainage device, resulting in intracranial damage and increasing the workload of medical staff; [0004] 2. Keep the inside of the suction pipe sealed when ...
