3D operation guide plate for cerebral hemorrhage operation

Abstract

The invention discloses a 3D operation guide plate for a cerebral hemorrhage operation. The 3D operation guide plate comprises a base, a puncture part supported by the base and a fixing part connectedwith the base and fixed to the surface of a human body. The fixing part comprises a fixing band tightly attached to the brain in a winding mode and a fixing patch attached to the fixing band, and concave positioning points which are embedded with the fixing patch to fix the base are arranged on the lower surface of the base; and the puncture part comprises a connecting section connected with thebase and a puncture guide section used for puncture positioning, wherein the connecting section is hollow in inner part, and a guide channel is formed in the puncture guide section. Compared with theprior art, the 3D operation guide plate for cerebral hemorrhage operation is obvious in artificial bony landmark, firm and free of displacement, the range of the operation guide plate can be freely designed, the operation process is simplified, and the operation accuracy is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a 3D surgical guide for cerebral hemorrhage surgery. Background technique [0002] With the widespread use of 3D printing technology in the medical field, minimally invasive surgery using 3D printed surgical guides has become a good surgical method for patients with cerebral hemorrhage. Through preoperative CT scan positioning, the approximate position of the hematoma on the body surface is estimated, and the puncture path is calculated. , puncture angle and puncture depth. [0003] In the prior art, there are 3D printed surgical guides for minimally invasive puncture surgery of cerebral hemorrhage. Generally, existing bony landmarks in the human body are selected, including the bridge of the nose, auricle, and eyebrow arch. After establishing a preoperative 3D model, combined with the position of the puncture point, a 3D printed surgical guide was designed based on the existin...

Problems solved by technology

[0003] In the prior art, there are 3D printed surgical guides for minimally invasive puncture surgery of cerebral hemorrhage. Generally, existing bony landmarks in the human body are selected, including the bridge of the nose, auricle, and eyebrow arch. After establishing a preoperative 3D model, combined with the position of the puncture point, a 3D printed surgical guide was designed based on the existing bony landmarks of the human body. The puncture sites and puncture requirements require personalized design of the shape and size of the surgical guide, resulting in poor matching and easy displacement of the surgical guide, especially the transfrontal or transtemporal puncture will lead to an overly large surgical guide model, long production time, and increased consumables , to delay the best time for surgery
