Anti-damage directional guide subdural drainage tube suite

Abstract

The invention relates to the field of medical instruments, in particular to an anti-damage directional guide subdural drainage tube kit. The anti-damage directional guide subdural drainage tube kit comprises a drainage tube implanting sleeve, a top opening is formed in the top of the drainage tube implanting sleeve; a positioning skirt edge is arranged on the outer edge of the top opening; a drainage tube leading-out hole is formed in the bottom of the drainage tube implanting sleeve; and an arc-shaped curvature guide platform is arranged on one side of the drainage tube guide-out hole. Blood vessels, blood supply arteries, drainage veins, bridge veins and arachnoid particles exist on the surface of the brain tissue cortex; the drainage tube is inserted into the drainage tube, so that bridge veins, drainage veins on the brain surface and the like can be effectively avoided, and damage to blood vessels is avoided. On the basis of the arc-shaped curvature guide platform, the drainage tube can smoothly turn into the subdural space and enter the encephalic in parallel; therefore, 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 field of medical devices, in particular to an anti-injury directional guide subdural drainage tube set. 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 is located on the side with the largest hematoma diameter, such as the apical tubercle or the top of the temporum, to locate the surgical incision. 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 incision about 3.5 cm in length is ma...

Problems solved by technology

[0009] In order to make up for the deficiencies of the prior art, the present invention provides an anti-injury directional guide subdural drainage tube set, 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 that the drainage tube is inserted into the subdural space. The problem of localized brain damage caused by excessive insertion of the tip into the brain
