For solving the problem being difficult to the position of accurately locating focus in prior art, this utility model provides a kind of can carry out exact space location to patient's focus and use simple and convenient three-dimensional surgical navigational film.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is:
A kind of three-dimensional surgical navigational film, comprise the paper-tear picture layer, pad pasting layer and the developing layer that stack gradually from bottom to top, paper-tear picture layer is covered in and pastes film surface and for protector rete before use, developing layer is provided with crisscross grid lines, and grid lines is provided with coordinate digital; The one side that pad pasting layer contacts with paper-tear picture layer is adhesive faces, and adhesive faces is provided with the painted scale for leaving the marking at patient, and developing layer is provided with the development scale for irradiating development at X-ray, and development scale overlaps with painted scale; Wherein painted scale is drawn by coloring matter; Development scale is made up of the lead that can develop under X-ray or steel or titanium alloy; Pad pasting layer is made up of medical macromolecular materials, and thickness is 0.03-0.2 millimeter; Developing layer is made up of medical macromolecular materials, and thickness is 0.03-0.6 millimeter; Paper-tear picture layer is made up of papery, and thickness is 0.1-0.8 millimeter; The binding agent that the adhesive faces of pad pasting layer uses is acryloid cement.
Further, this three-dimensional surgical navigational film, comprises the first surgical navigational film and the second surgical navigational film, and the first surgical navigational film and the second surgical navigational film can be wholely set or be provided separately.
Further, pad pasting layer and developing layer are integrated into one deck, namely form development pad pasting layer, and three-dimensional surgical navigational film comprises paper-tear picture layer and development pad pasting layer.
Further, the material of pad pasting layer and developing layer or development pad pasting layer is polyurethane film.
Further, the air penetrability of pad pasting layer and developing layer or development pad pasting layer is 385 ~ 825g/m
2/ 24hrs.
Technique effect of the present utility model is, its design philosophy to be combined with x-ray fluoroscopy by projection line principle to carry out three-dimensional fix accurately to the focus in patient body, and technical scheme is ingenious.By arranging the first surgical navigational film and the second surgical navigational film, first surgical navigational film is affixed on patient back, second surgical navigational film is affixed on patient's sidepiece, three-dimensional localization accurately can be carried out to the affected area of patient, shorten operating time, reduce the wound of patient, reduce intraoperative blood loss, reduce the misery of patient, improve the success rate of operation, X-ray also can be avoided simultaneously to the Health cost of surgical staff and patient.

Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in further detail.Should be appreciated that specific embodiment described herein only in order to understand this utility model, and be not used in restriction this utility model.
As shown in Figure 1, this utility model provides a kind of principle schematic of three surgical navigational films.Suppose that A point is the affected area of patient.From the angle shot X-ray overlooked, obtain the projection A1 of A point at horizontal plane, thus determine that focus A point is in the position of horizontal plane, again from the angle shot X-ray of side-looking, obtain the projection A2 of A point in side-looking plane, thus the height of focus A point distance horizontal plane can be determined, therefore just obtain the three-dimensional space position of focus A point.In actual operation process, generally with α angle for operation entrance angle, after the height A A1 being obtained focus distance patient back flat by X-ray, doctor can obtain suitable operation incision path A 3A.
As shown in Figure 2, this utility model provides a kind of three-dimensional surgical navigational film.This utility model comprises the paper-tear picture layer 13, pad pasting layer 14 and the developing layer 15 that stack gradually from bottom to top; paper-tear picture layer 13 is covered in pad pasting layer 14 surface and for protector rete 14 before use; developing layer 15 is provided with crisscross grid lines, and grid lines is provided with coordinate digital.The one side that pad pasting layer 14 contacts with paper-tear picture layer 13 is adhesive faces, and adhesive faces is provided with the painted scale for leaving the marking at patient, and developing layer 15 is provided with the development scale for irradiating development at X-ray, and development scale overlaps with painted scale.Wherein painted scale is drawn by coloring matter.Development scale is made up of the lead that can develop under X-ray or steel or titanium alloy.Pad pasting layer 14 is made up of medical macromolecular materials, and thickness is 0.03-0.2 millimeter.Developing layer 15 is made up of medical macromolecular materials, and thickness is 0.03-0.6 millimeter.Paper-tear picture layer 13 is made up of papery, and thickness is 0.1-0.8 millimeter.The binding agent that the adhesive faces of pad pasting layer 14 uses is acryloid cement.
As shown in Figure 3, three-dimensional surgical navigational film provided by the utility model comprises the first surgical navigational film 10 and the second surgical navigational film 12, first surgical navigational film 10 and the second surgical navigational film 12 and can be wholely set or be provided separately.Before surgery, the paper-tear picture layer 13 of three-dimensional surgical navigational film is torn off to expose pad pasting layer 14, then sticking pad pasting layer 14 is attached to patient's affected area, first surgical navigational film 10 is affixed on patient back, second surgical navigational film 12 is affixed on patient's sidepiece, pad pasting layer 14 and developing layer 15 have just been stayed on patient skin, developing layer 15 is stayed on patient skin to ensure the smooth of pad pasting simultaneously, and then X-ray shooting is carried out to lesions position, first surgical navigational film 10 is taken from overlooking visual angle and takes from side-looking visual angle to the second surgical navigational film 12 respectively, namely the development scale of developing layer 15 can demonstrate position under X-ray irradiates.Doctor is when performing the operation, lesion localization can be carried out easily according to the corresponding patient of the scale on developing layer 15 visible pigment scale with it, doctor can calculate operation incision path according to the height A A1 of the focus distance patient back flat obtained, thus performs operation.
Alternatively, as shown in Figure 4, pad pasting layer and developing layer can be integrated into one deck, namely form development pad pasting layer 16, three-dimensional surgical navigational film is made up of paper-tear picture layer 17 and development pad pasting layer 16.
Further, in order to improve the safety of operation, pad pasting layer 14 and developing layer 15(or development pad pasting layer 16) material be polyurethane film.
Further, in order to improve the safety of operation, pad pasting layer 14 and developing layer 15(or development pad pasting layer 16) air penetrability be 385 ~ 825g/m
2/ 24hrs.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
