Anti-injury directional guide subdural drainage method

Abstract

The invention relates to the technical field of intracranial effusion drainage,and concretely relates to an anti-injury directional guide subdural drainage method. The method comprises the following steps: (1) accurately positioning a skull drilling position, cutting a scalp, and drilling a bone hole at a positioning point; (2) inserting the bone hole fixing sleeve into the bone hole, inserting a drainage tube implanting sleeve into the bone hole fixing sleeve, and then inserting a drainage tube from the drainage tube implanting sleeve; (3) connecting the tail end of the drainage tube with an injector, sucking subdural effusion or blood through the injector, injecting normal saline at the same time, and carrying out repeated flushing is carried out till clear; (4) drawing out the drainage tube, rotating the drainage tube implanting sleeve by hand, switching to another direction, and repeatedly sucking and washing along the drainage tube; and (5) taking out the bone hole fixing sleeve and the drainage tube implanting sleeve, subcutaneously leading out the drainage tube from the side of the incision, fixing the drainage tube, and connecting an external drainage device. The drainage direction and angle can be accurately positioned and oriented, the drainage tube can smoothly turn into the subdural space, and local brain injury caused by the fact that the drainage tube is difficult to turn into the subdural space is effectively avoided.

Description

Technical field: [0001] The invention relates to the technical field of drainage of intracranial effusion, in particular to an anti-injury directional guiding subdural drainage method. Background technique: [0002] At present, for the treatment of chronic subdural hematoma and effusion, the most important treatment method is drilling, aspiration and lavage. The operation method is: drilling and drainage operation method (local anesthesia as an example): the patient is placed in supine position, the head is turned to the healthy side, and the hematoma on the side where the hematoma occurs is located at the site with the largest hematoma diameter, such as the apical tubercle or the top of the temporum. Local skin anesthesia with % lidocaine to the galeal aponeurosis, temporalis muscle and periosteum. After the anesthesia is effective, Aner Iodine is used to disinfect the operation area, a sterile surgical towel and antibacterial film are spread, and a longitudinal linear inci...

Problems solved by technology

[0015] In order to make up for the deficiencies in the prior art, the present invention provides an anti-injury directional guiding subdural drainage method, which solves the problem that the drainage tube causes damage to the blood vessels at the drilling hole in the skull, and solves the problem when the drainage tube is inserted into the skull through the drilling hole in the skull. The problem of brain injury caused by the hard curvature of the drainage tube solves the problem of injury or bleeding caused by the excessive insertion of the tip of the drainage tube into the brain
