Individualized Stereotaxic Headband Placement Bracket

Abstract

The invention discloses an individualized stereotactic head ring placement bracket, which includes a base ring arranged at the bottom, a front pillar, a rear pillar, a left pillar, a right pillar, a cross laser alignment device, and the like; And both sides of the cross laser alignment device are respectively provided with adjusting and fixing screw ejector rods, and the ends of the front and rear ejector posts are respectively provided with top supports and adjustment screw ejector rods; the bottom of the base ring and the head ring Fitted top with detachable attachment. The individualized stereotaxic headband placement bracket provided by the present invention has the characteristics of being widely used, simple and practical, safe (no pain) and reliable, and accurate in positioning (ensuring that the stereotaxic headband is highly parallel to the AC-PC plane).

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an individualized stereotaxic head ring placement bracket. Background technique [0002] As we all know, accurate anatomical positioning is the premise of implementing stereotaxic functional neurosurgery, and it is also the basis of all stereotactic surgery. [0003] The anterior commissure (AC) and posterior commissure (PC) of the human brain are recognized as the positioning landmarks of the anatomical structure in the brain due to their constant positions and relative distances. Therefore, it is particularly important to determine the anterior and posterior commissures through imaging before surgery. However, since AC and PC are located in the deep part of the brain, it is difficult to directly measure them. Therefore, it is the best method for brain stereotaxic surgery to try to make the stereotaxic head ring (head ring for short) parallel to the AC-PC plane so as to ...

Problems solved by technology

[0007] However, analyzing the traditional auxiliary structures mentioned above (such as figure 1 and figure 2 Two kinds of auxiliary structures shown), there are some obvious technical defects in turn: for example: traditional supporting auxiliary structures (ie, such as figure 1 The plastic rod in the middle) needs to be inserted into the external auditory canal of the patient, and they will feel uncomfortable to the patient; at the same time, when the position of the head ring is adjusted, the plastic rod will be driven to sting the patient's ear, so this traditional auxiliary structure is not convenient to apply (At the same time, if figure 2 In the application structure of the adjustable belt, repeated tightening of the scalp during specific use will also bring discomfort to the patient)

At the same time, the traditional auxiliary structure cannot finely adjust the position of the head ring, and cannot meet the modern precise positioning adjustment requirements

In addition, the above-mentioned traditional auxiliary structures all require two or more assistants to assist in the operation and observe the parallel situation; obviously, this method is not only inaccurate in parallel positioning, but also may waste more time
