Problems solved by technology

[0003] Most of the currently used stereotaxic devices use a frame structure. The positioning principles use rectangular coordinates, spherical coordinates, and half-circle measurement, etc. The structure is complicated, and manual calculations will inevitably cause positioning errors. For small targets , positioning error means damage to other tissues, even important organs, nerves, blood vessels, etc., resulting in serious adverse consequences
Although some stereotaxic equipment uses electrical components and computer control, because it must be operated under the real-time monitoring of CT, the patient is injured by X-rays for a long time, and the doctor and patient are blocked. Influenced by the structure, interventional treatment at multiple points in a small area cannot be performed at one time, which will affect the treatment effect

Embodiment 1

[0029] According to attached figure 1 The beam structure is as follows:

[0030] The horizontal linear transmission structure (1) consists of a horizontal beam-type linear slide rail (1.3) and a driving screw (1.2) that slides horizontally on the beam-type linear slide rail, and the driving screw is fixed on (B) , the driving screw is connected with a stepping motor (1.1), the stepping motor is located at the top of the beam-type linear slide rail, the vertical linear transmission structure (2) consists of a vertical linear slide rail (2.2), and an online The driving screw (2.1) that slides up and down on the slide rail is composed of a driving screw connected to the angular displacement sensor (4) and then connected to the stepping motor (5.1) that guides the pan / tilt rotation mechanism (5), and the stepping motor (5.1 ) is connected with the pitch mechanism (6) of the guiding platform, the inclination sensor (7) is located above the guiding platform, the elastic locking mec...

Embodiment 2

[0033] According to attached figure 1 The cantilever type is adopted, and one end of the beam type linear slide rail (13) with the beam overturning mechanism (3) is installed on the movable base (A) with casters. All the other structures are with embodiment 1.

Description

Technical field: [0001] The invention relates to a tomography image information based on CT, which can accurately restore the tomographic direction and tomographic angle of CT under the real-time monitoring state separated from CT, accurately repeat the spatial position described by the tomographic image, and realize high precision, multi-point, Repeatable numerically controlled stereotaxic method and system thereof. Background technique: [0002] Minimally invasive surgery was invented by a French doctor in the late 1980s. Since it was introduced to our country for more than 20 years, this technology has achieved rapid development in our country because of the small trauma, less pain and quick recovery of patients. Along with the development of minimally invasive surgery, the new technology of stereotaxic is also being continuously improved and innovated. With the wide application of computed tomography (CT), it has opened up a new field and broad prospects for the applic...
