Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] An embodiment of the puncture guide used in the puncture guide method of the present invention is as follows: Figure 6 to Figure 8 As shown, the puncture guiding device includes a base 1, a fixing device, a laser light 13, a laser light direction adjusting device and a laser light position adjusting device.

[0037] The fixing device is arranged at one end of the base 1 in the length direction, and is used to fix the body of the patient's surgical site, such as the head.

[0038] Such as Figure 6 As shown, in this embodiment, the fixing device adopts the following structure: the fixing device includes a fixing ring 2 , and fixing foot mechanisms arranged radially on the fixing ring 2 at intervals.

[0039] The fixing ring is arc-shaped, and its two ends are connected with the base 1 . A connection structure in which an installation groove 9...

Abstract

The invention discloses a use method of a puncture guide device. The use method comprises the following steps: firstly, positioning a surgical part of a patient; and then scanning the surgical part of the patient with CT (computed tomography), and connecting a puncture point and a surgical target point in CT imaging to obtain a puncture path and a puncture depth; calculating a projection angle alpha of an included angle between the puncture path and a sagittal line on a coronal plane, and a projection angle beta of an included angle between the puncture path and a coronal line on a sagittal plane by a CT machine system; adjusting the laser lamp light beam direction and the puncture path direction of the puncture guide device to be conform according to the projection angle alpha and the projection angle beta; adjusting the puncture guide device, so that the laser lamp light beams point to the surgical puncture point; and ensuring that a puncture needle is straight and the tail end of a puncture needle is positioned on a laser lamp light beam line in the follow-up guide. The use method provided by the invention realizes the puncture surgery guide, and is accurate and reliable, and is simple and convenient to use.

Description

technical field [0001] The invention relates to a method for auxiliary guidance of surgical puncture. Background technique [0002] Accurate guidance for puncture surgery has always been a clinical problem. For example, the traditional method of puncturing the trigeminal ganglion through the foramen ovale clinically is the Hartel puncture method: the patient is placed in the supine position, and three points are determined on the face (such as Figure 1 to Figure 5 Shown): Point A is the puncture point about 2.5-3.0cm outside the corner of the patient's mouth; Point B is the midpoint of the pupil on the affected side; Point C is 2.5-3.0cm in front of the patient's external auditory canal, which is also the midpoint of the zygomatic arch. This method uses the anatomical landmarks of the human body for positioning, and the accuracy for patients with differences in anatomy is poor, which can easily lead to puncture failure and complications. At the same time, for unskilled ope...
