Description

Positioning scale for nerve intervention operation

Technical Field

The utility model relates to a neural intervention operation technical field, concretely relates to neural intervention operation positioning scale.

Background

The interventional therapy is a general name of a series of technologies for introducing specific instruments into a diseased part of a human body through natural pores or tiny wounds by using puncture needles, catheters and other interventional devices under the guidance and monitoring of imaging equipment such as a digital subtraction angiography machine, CT, ultrasound, magnetic resonance and the like, has the advantages that ① can complete the therapy without incision and without wound or skin incision of only a few millimeters, the wound is small, ② most patients only need local anesthesia rather than general anesthesia, so that the risk of anesthesia is reduced, ③ has small damage to normal tissues, is quick to recover and has short hospitalization time, and ④ can also well treat the intervention of high-age critical patients who cannot tolerate the operation or patients who do not have the chance of the operation.

The whole interventional therapy is conducted under the guidance and monitoring of the imaging equipment, but in the operation process, the change of the relative position of the blood vessel under the roadmap can be caused due to the influence of the movement of a human body or the breathing amplitude, so that an operator can not accurately judge the interventional angle and size, and the operation accuracy is reduced.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides a neural intervention operation positioning scale can develop under the ray irradiation, supplementary operating personnel accurate operation.

The utility model provides a pair of neural intervention operation positioning scale, include not high shadowy scale body under the ray irradiation, the upper surface of scale body is provided with the scale of developing under the ray irradiation, and the lower surface is provided with fixed establishment, the scale body passes through fixed establishment is fixed in human skin.

Example 1

As shown in fig. 1-3, this embodiment provides a neural intervention operation positioning scale, include the not shadowy scale body 1 under the radiation, the scale body 1 adopts transparent plastics to make, the upper surface of scale body 1 is provided with scale 1a that develops under the radiation, and the lower surface is provided with fixed establishment, scale body 1 passes through fixed establishment is fixed in human skin. The fixing mechanism is made of flexible materials.

The positioning scale can be fixed at any position of a human body through the fixing mechanism, is suitable for different operation positions, the scale body 1 cannot be developed under the radiation irradiation, the operation is guaranteed to have a good operation visual field to the maximum extent, the scale 1a of the development can provide accurate reference for the intervention, and the accuracy of the intervention operation can be improved.

In implementation, the scale 1a has two structures, one is that the scale 1a protrudes out of the upper surface of the scale body 1 and is made of lead, and the thickness of the scale 1a is 0.2-1 mm. The ray has a weak ability to penetrate lead, and a clear image can be formed. The other is that the scale 1a includes a groove engraved on the scale body 1, and the groove is filled with a developing material. The developing material is capable of developing and forming a clear scale 1a under irradiation of radioactive rays. The developing material is a composite material of acrylate polymer resin and an inorganic developing material (barium sulfate, zirconium dioxide and the like).

Because medical instruments need to be strictly disinfected and common small articles are disposable articles, the fixing mechanism is connected with the scale body 1 in a detachable mode. Can dismantle fixing mechanism and handle after using, can reuse after changing new fixing mechanism for scale body 1, reduce the consumption of scale body 1, save the cost. Specifically, a slot 4 is formed in the fixing mechanism, and the scale body 1 is connected with the fixing mechanism through the slot 4. The plug-in connection is convenient and reliable, and the replacement of the fixing mechanism can be rapidly completed.

The fixing mechanism is an adhesive layer 2. The adhesive layer 2 is stable in adhesion, and the staff gauge body 1 is prevented from falling off during an operation.

The scale body 1 is made of flexible materials, and adaptability of the scale body 1 can be improved.

Example 2

Referring to fig. 4, the main structure of this embodiment is the same as that of embodiment 1, and this embodiment mainly proposes another embodiment for the fixing mechanism, where the fixing mechanism includes a patch 3, the patch 3 is made of a flexible material, and a plurality of micro fixing stabs 3a are further disposed on a surface of the patch 3 away from the scale body 1. The fixing pricks 3a can pierce the skin of a patient to fix the scale body 1, and no scar is left. Can solve the problem that partial skin of a patient can not be glued, and the glue can be torn when being taken down, so that pain can be brought to the patient.

The fixing spine 3a is conical, the maximum diameter of the fixing spine 3a is 0.1-0.5mm, and the length of the fixing spine 3a is 0.1-1 mm. Because the size of the fixed thorn 3a is very small, the action time is short, the pain of the patient is small, no obvious scar is left after the fixed thorn 3a is taken down, and the small pierced opening of the fixed thorn 3a on the skin is self-healing.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
