3D-printed guide bracket for cerebral hemorrhage minimally invasive surgery and preparation method thereof

Abstract

The invention discloses a 3D-printed guide bracket for cerebral hemorrhage minimally invasive surgery and a preparation method thereof, and belongs to the technical field of medical appliances. The guide bracket comprises a craniofacial attaching part, wherein the lower surface of the craniofacial attaching part is attached to the surface of the craniofacial part, and a limiting sleeve is arrangedon the right side surface of the craniofacial attaching part. According to the 3D-printed guide bracket for cerebral hemorrhage minimally invasive surgery and the preparation method thereof, the craniofacial attaching part, the limiting sleeve and a guiding branch pipe are arranged, and the craniofacial attaching part, the limiting sleeve and the guiding branch pipe are manufactured through a 3Dprinting technology, so that the craniofacial attaching part is closely attached to the craniofacial part of a patient; the facial surface of the patient is sleeved with the limiting sleeve, and the guiding direction of the guiding branch pipe is aligned with the hematoma center, so that the problem of inaccurate puncture positioning of the hematoma position of the patient by a doctor during minimally invasive surgery is solved, the operation is convenient, the puncture positioning accuracy rate and the puncture operation success rate are improved, and the puncture positioning to the patient is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a 3D printed guide bracket for minimally invasive surgery of cerebral hemorrhage and a preparation method thereof. Background technique [0002] Cerebral hemorrhage has a high disability and fatality rate. The healing of cerebral hemorrhage is closely related to the bleeding site, bleeding volume and rescue time. Craniofacial musculature and digestive visceral tissue are completely different. They not only pass through important nerve fiber bundles, but also pass through the dense network of blood vessels that dominate the functional area. The operation is extremely difficult and requires extremely high precision in the operation. [0003] Minimally invasive hematoma puncture for cerebral hemorrhage generally relies on CT positioning, and selects the scalp puncture point, puncture direction and puncture depth according to the maximum level of intracranial hematoma.

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a 3D-printed guide bracket for minimally invasive surgery of cerebral hemorrhage and its preparation method, which solves the problem that due to the irregularity of the shape of the skull, especially the need for the catheter to form a certain When adjusting the angle, the catheterization path, direction and depth of the catheterization are often not precisely controlled, and the puncture direction is prone to deviation, resulting in poor surgical results.
