Description

The stereotaxis 3-D measurer

Technical field

The utility model relates to the accessory on a kind of medicine equipment, specifically a kind of stereotaxis 3-D measurer simple in structure, easy to operate, with low cost.

Background technology

Along with improving constantly of medical technique level, stereotactic apparatus is widely used in neurosurgery, basis cranii surgery, oral surgery and the otorhinolaryngologic precision navigation positioning operation.Horseley-Clarke technique is based on main frame, form the symcenter of a three-dimensional, carry out connection by CT, MRI scanning board and main frame, obtain the gauge point of three-dimensional prompting on various tomoscans plane, determine the three-dimensional coordinate of arbitrfary point in its specific region by various calculating means; Guiding and operation be to rely on XYZ to realize to axle and bow-shaped arm and the various annexes that are attached thereto.

At present, when in the location navigation operation, carrying out the surface indicia three-dimensional measurement, usually use the CCD camera, cardinal principle is by infrared and obtains the reflection of arranging according to certain rules in the space and accept spherula, determine the three-dimensional numerical value of certain point of space by internal calculation, what obtain like this is the indirect data.Use the CCD camera to be subjected to more multifactor influence easily, the precision of influence operation, and complex structure cost an arm and a leg, and are unfavorable for promoting the use of.

The utility model content

Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of stereotaxis 3-D measurer simple in structure, easy to operate, with low cost.

Technical scheme: for solving the problems of the technologies described above, stereotaxis 3-D measurer of the present utility model comprise rotation axis, X to axle, Y to axle and Z to axle, described Y is connected with rotation axis respectively to axle with Z to axle; Described X is connected with rotation axis by linking arm to axle; Described X is provided with the registration pen to axle, and the registration pen is installed in X on axle by slide block.

When the three-dimensional data mode was manually read in employing, described registration pen was the fixing registration pen of length.

When the three-dimensional data mode is read in employing automatically, described registration pen is the registration pen of adjustable in length, the registration pen elongates or shortens by the screw propulsion mode, the turnover of registration pen partly is equipped with by angle and changes the first displacement code-disc that shows length, be equipped with in the described rotating shaft Y to axle and Z to the total angle code-disc of axle, described X is equipped with the second displacement code-disc on axle.

Stereotaxis 3-D measurer of the present utility model in use, the utility model is installed in a side of stereotactic apparatus main frame, with staple head is fixed on the main frame again,, makes certain point on the registration nib arrival head by regulating the position of registration pen.The utility model has two kinds of modes that read three-dimensional data: the one, manually read mode, and the 2nd, read mode automatically.When adopting part work and part study to get the three-dimensional data mode, the length of registration pen is fixed, with the nib of registration pen aim at adjustable space more arbitrarily, again by read arrive this point need from initial point (coordinate: 0,0,0) X of Yi Donging to axle, Y to axle and Z corresponding digital on axle determine X, Y, the Z value of this point; When the three-dimensional data mode is read in employing automatically, promote registration pen deeply or shallowly go out and determine by the helical rotation mode by the first displacement code-disc, extending or the shortening of length, be combined in X to the second displacement code-disc of installing on the axle, the Y that in rotating shaft, installs to axle and Z to the total angle code-disc of axle, the common three-dimensional coordinate data of determining the registration nib in specific any spatial point, the particular location data-signal in space is imported by serial ports of computers.

Beneficial effect: stereotaxis 3-D measurer of the present utility model is simple in structure, easy to operate, in use is not subjected to the influence of extraneous factor, and it is very accurate to measure; Can demarcate and manually read three-dimensional numerical value by machinery, also can realize reading automatically three-dimensional numerical value by code-disc is installed; And with low cost, help promoting the use of.

Description of drawings

Accompanying drawing is the new structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

As shown in drawings, stereotaxis 3-D measurer of the present utility model comprise rotation axis 1, X to axle 2, Y to axle 3 and Z to axle 4, Y is connected with rotation axis 1 respectively to axle 4 with Z to axle 3; X is connected with rotation axis 1 by linking arm to axle 2; X is provided with registration pen 5 to axle 2, and registration pen 5 is installed in X on axle 2 by slide block.

When the three-dimensional data mode was manually read in employing, registration pen 5 was the fixing registration pen of length; When the three-dimensional data mode is read in employing automatically, registration pen 5 is the registration pen of adjustable in length, registration pen 5 elongates or shortens by the screw propulsion mode, the rotating part of registration pen 5 is equipped with by angle and changes the first displacement code-disc 6 that shows length, be equipped with in the rotating shaft 1 Y to axle and Z to the common angle code-disc 7 of axle, X is equipped with the second displacement code-disc 8 on axle 2.

Stereotaxis 3-D measurer of the present utility model in use, the utility model is installed in a side of stereotactic apparatus main frame, with staple head 9 is fixed on the main frame again,, makes certain point on the nib arrival head 9 of registering pen 5 by the position of adjusting registration pen 5.The utility model has two kinds of modes that read three-dimensional data: the one, manually read mode, and the 2nd, read mode automatically.When adopting part work and part study to get the three-dimensional data mode, the length of registration pen 5 is fixed, with the nib of registration pen 5 aim on the head 9 more arbitrarily, again by read arrive this point need from initial point (coordinate: 0,0,0) X of Yi Donging to axle 2, Y to axle 3 and Z corresponding digital on axle 4 determine X, Y, the Z value of this point; When the three-dimensional data mode is read in employing automatically, registration pen 5 advances by rotating, extending or the shortening of length, at X the second displacement code-disc 8 is installed on axle 2, the coordinate of X is determined by the second displacement code-disc 8, Y can determine that this particular location data-signal is imported by serial ports of computers on the head 9 to axle 3 and Z by the first displacement code-disc 6 and the angle code-disc in the rotating shaft 17 of registration pen 5 turnover parts to the delta data of axle 4.

The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
