Individualized stereotactic head ring placing support

Abstract

The invention discloses an individualized stereotactic head ring placing support which comprises a base ring arranged at the bottom, a front face support pillar, a back face support pillar, a left side support pillar, a right side support pillar, cross laser alignment devices and the like. The two sides of each cross laser alignment device are each provided with an adjusting and fixing screw ejector rod, the tail end of the front face support pillar and the tail end of the back face support pillar are each provided with a top supporting and adjusting screw ejector rod, and the bottom of the base ring is attached to and detachably connected with the top of a head ring. The individualized stereotactic head ring placing support has the advantages that the application range is wide, simpleness, practicability, safety and reliability are achieved, a painful feeling does not occur, the position positioning is accurate, and it is guaranteed that the stereotactic head ring is parallel to the AC-PC plane height.

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
