Abstract

The utility model relates to a three-dimensional stereotaxic apparatus, which is characterized in that the three-dimensional stereotaxic apparatus comprises a frame (1), an X directional guide rail (5) arranged on the frame (1), a Y directional guide rail arranged on the frame (1), a cambered plate arranged on the X directional guide rail (5) and the Y directional guide rail (8), and a Z directional regulating mechanism arranged on the cambered plate. The center of the frame (1) is provided with a hole; the periphery of the hole is provided with a plurality of skull positioning nails (3). The utility model has the advantages that the cambered plate and a guide cambered plate has large regulating range, and is capable of marking the projection of a focus on the surface of a scalp; the guide cambered plate can be regulated to more near to a target point.

Description

Three-dimensional brain solid positioner

This utility model relates to a kind of department of cerebral surgery medical apparatus and instruments.

In the prior art, the name that Patent Office of the People's Republic of China disclosed CN1050676A on April 17th, 1991 is called the application for a patent for invention of " universal directional multifunctional three dimensional direction finder for brain ", and what this technology adopted is the spherical coordinates location, and guidance system has universal function.This position finder can not the selection operation apparatus and scalp between distance, operate miss increases when causing performing the operation.In addition, its guiding mechanism is not open, the action of hands when hindering operation.

The purpose of this utility model is to provide a kind of three-dimensional brain solid positioner that can improve the operation technique degree of accuracy.

The technical solution of the utility model is: a kind of three-dimensional brain solid positioner, it comprises framework, be arranged at X on the described framework to guide rail, be arranged at Y on the described framework to guide rail, be arranged at described X to guide rail and Y the arc plate on guide rail, be arranged at Z on the described arc plate to governor motion, described framework central authorities have the hole, be provided with a plurality of skull locating pins around the hole, framework has X to guide groove along directions X, framework has Y to guide groove along the Y direction, described X is slidingly connected to guide groove to guide rail and described Y, described Y is slidingly connected to guide groove to guide rail and described X, described arc plate and described X all are slidingly connected to guide rail to guide rail and described Y, slidely connect guide plate on the described arc plate, this guide plate is provided with longitudinally Z to column, described Z is connected with described guide plate slides to the lower end of column, and described Z longitudinal sliding motion on column is connected with guiding arc plate.

This utility model compared with prior art has following advantage:

The range of accommodation of arc plate and guiding arc plate is big, can go out focus in the projection mark of scalp surface so that perform the operation, and the guide plate plate can be regulated closelyer from target spot, makes the operation technique time error reduce.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is a perspective view of the present utility model; Wherein:

[1], framework; [2], X is to guide groove; [3], skull locating pin; [4], Y is to guide groove; [5], X is to guide rail; [6], lower curved plate; [7], upper curved plate; [8], Y is to guide rail; [9], operating apparatus; [10], guiding arc plate; [11], Z is to column; [12], guide plate;

Embodiment: referring to accompanying drawing, a kind of three-dimensional brain solid positioner, it comprises framework [1], be arranged on the described framework [1] X to guide rail [5], be arranged on the described framework [1] Y to guide rail [8], be arranged at described X to guide rail [5] and Y to the arc plate on the guide rail [8], be arranged at Z on the described arc plate to governor motion.Described framework [1] central authorities have the hole, are convenient to be enclosed within on the head, are provided with four skull locating pins [3] around the described hole, and the both sides of framework [1] have X to guide groove [2] along directions X, and the both sides in addition of framework [1] have Y to guide groove [4] along the Y direction.Described X to guide rail [5] be inserted in described Y in guide groove [4] and both can on the Y direction, be slidingly connected, described Y to guide rail [8] be inserted in described X in guide groove [2] and both on directions X, be slidingly connected.Described arc plate be positioned at described X to guide rail [5] and described Y to the top of guide rail [8], described arc plate and described X all are slidingly connected to guide rail [8] to guide rail [5] and described Y.On described arc plate, slidely connect guide plate [12], this guide plate [12] is provided with longitudinally Z to column [11], described Z is slidingly connected to the lower end and the described guide plate [12] of column [11], and described Z goes up longitudinal sliding motion to column [11] and is connected with guiding arc plate [10].

Described arc plate is made up of upper curved plate [7], [6] two of lower curved plates, the curvature of two blocks of arc plates is identical, the center of circle is identical and be slidingly connected mutually, described guide plate [12] is arranged on the described upper curved plate [7], and described lower curved plate [6] is slidingly connected to guide rail [8] to guide rail [5] and Y with described X respectively.

Described guiding arc plate [10] is provided with operating apparatus [9], and described guiding arc plate [10] and the described Z rotating shaft by level between column [11] is pivotally connected.

Be slidingly connected between above-described two parts, also should between two parts, locking device be set, make two parts that are slidingly connected mutually after mixing up the position, can lock.
