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.

Abstract

The invention belongs to the technical field of medical equipment and discloses a 3D printed cerebral hemorrhage puncture drainage path positioning device and a preparation method thereof. The positioning device comprises a fixed seat provided with an attachment part attached to the brain outline of a patient, a guide support is arranged on the fixed seat, and a puncture channel pointing to a hematoma center of the brain of the patient is formed in the guide support. The problem of inaccurate puncture positioning on the patient is solved, the puncture positioning accuracy is improved, the lifesafety of the patient is guaranteed, the operation is convenient, and the success rate of puncture surgery is increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a 3D printed cerebral hemorrhage puncture drainage path positioning device and a preparation method thereof. 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...
