Method for assisting cerebral hemorrhage puncture and drainage by 3D printing fixing device

Abstract

The invention belongs to the technical field of medical instruments, and discloses a method for assisting cerebral hemorrhage puncture and drainage by a 3D printing fixing device. The method comprisesthe following steps: scanning the brain of a patient by an image device to obtain an image file data packet; constructing a fixing device model by medical modeling; obtaining the fixing device for assisting the cerebral hemorrhage puncture and drainage with a 3D printing method; fixing the fixing device on the brain of the patient, and puncturing the brain of the patient by putting a drainage tube along a puncture channel of the fixing device to suck hematoma. The fixing device is designed completely according to three-dimensional data scanned and reconstructed by the brain of the patient, and perfectly fits the brain of the patient, the problem of different brain contours of different patients is solved, the method can adapt to any cerebral hemorrhage patients. The drainage tube can reach the hematoma center directly through the puncture channel, and accordingly, accuracy of puncture positioning is increased, and the success rate of puncture and drainage operation is increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a method for assisting puncture and drainage of cerebral hemorrhage by using 3D printing fixing equipment. Background technique [0002] Cerebral hemorrhage is a common neurological emergency, which endangers the life of the patient in severe cases, and leaves neurological deficits in mild cases. The disease is characterized by high morbidity, high mortality, and high disability rate. Conventional bone flap craniotomy is often used in traditional treatment methods, which is traumatic, expensive and has serious sequelae. Now a minimally invasive hematoma puncture technique for cerebral hemorrhage has been developed, which has the characteristics of small trauma, simple operation, quick effect, and small sequelae. residual rate. [0003] At present, minimally invasive hematoma puncture for cerebral hemorrhage generally relies on CT positioning, and the scalp p...

Problems solved by technology

At present, the following auxiliary orienting methods are generally used in the puncture of intracranial hematoma to increase the accuracy of the puncture: stereotaxic instrument and neuronavigation system. Puncture and catheterization after positioning scanning, although the surgical positioning is accurate and the precision is high, the surgical process is cumbersome and takes a long time. In clinical practice, most patients with cerebral hemorrhage are in critical condition, unconscious, restless, and are not suitable for the treatment of emergency patients.

The neuronavigation system has extremely high puncture accuracy under neuronavigation, but it is extremely expensive, cumbersome to use, time-consuming to operate, and requires more complicated technical training, etc., so it cannot be widely used and is not suitable for promotion and application in grassroots hospitals.
