Background
Ommaya's capsule is a common intracranial implant for neurosurgery, and is composed of a silica gel liquid storage bag which is embedded under the scalp and has a flat bottom end, and a silica gel tube, wherein one end of the silica gel liquid storage bag is connected with the liquid storage bag, and the other end of the silica gel tube is arranged in a ventricle or a focus. When in use, the needle head or the intravenous infusion needle can be connected with an injector, and the scalp is punctured into the liquid storage bag to extract cerebrospinal fluid or conduct continuous drainage, and the medicine can also be injected into the cranium through the liquid storage bag. Because of the special material of the liquid storage bag, the liquid storage bag can bear the needle head to puncture for many times without leakage. Clinically, the intravenous infusion needle is usually bent into an angle of 90-120 degrees manually, is punctured into the liquid storage bag and is connected with a drainage bag to continuously drain cerebrospinal fluid. When the needle is fixed, a sterile absorbent cotton ball is usually padded under the needle and fixed by using a medical adhesive tape, a transparent film patch or a medical application patch. Some units are fixed by sewing.
The fixing methods all have the problem of unstable fixation, and the needle head is easy to separate from the cyst cavity and even from the scalp due to the change of the head position of a patient and the traction caused by operations of extracting cerebrospinal fluid by a doctor and the like, so that the angle adjustment or repeated puncture is required, the tissue injury and infection risks are increased, and the service life of the Ommaya sac is shortened. Suture fixation causes additional trauma to the patient and may also damage the Ommaya sac and silicone tubing.
In addition, because patients have individual difference, the thicknesses of scalps at different parts are different, and the bending part of the puncture needle is also mainly judged by an operator, the distance between the bending part of the puncture needle and the scalps is different after the puncture needle is successfully punctured into the liquid storage bag, and the fixing of the puncture needle is difficult. In addition, it is sometimes clinically possible to have too deep or too shallow a puncture, resulting in an obstructed drainage and requiring adjustment of the depth of the puncture needle.
