[0002] Trigeminal nerve balloon compression surgery (PBC) is a minimally invasive neurological treatment. The basic method of the surgery is: the patient is under general anesthesia, and under the guidance of a C-arm, a puncture is made through the facial skin to reach the site where the trigeminal nerve exits the cranial cavity - the oval foramen. A balloon catheter is used to insert a McColl capsule, and the balloon expansion is used to moderately compress the trigeminal ganglion, fully blocking the pain neurons of the trigeminal nerve to achieve the purpose of treatment.

[0003] In traditional technology, the puncture point is usually located by drawing a line on the patient's face. However, this positioning method often requires adjusting the position of the line, which is cumbersome and easily leads to the problem of long positioning time. Utility Model Content

[0033] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0034] Embodiment 1:

[0035] See also Figure 1 and Figure 2 A positioner for trigeminal nerve balloon compression surgery comprises an arc-shaped support frame 1, and the positioner for trigeminal nerve balloon compression surgery also comprises:

[0036] A main positioning member 2 movably connected to the end of the arc-shaped support frame 1;

[0037] Such an arrangement enables the main positioning member 2 and the arc-shaped support frame 1 to move relative to each other, thereby facilitating the operator to adjust the position of the main positioning member 2 .

[0038] An auxiliary positioning member 3 slidably connected to the arc-shaped support frame 1;

[0039] Such an arrangement enables the auxiliary positioning member 3 to move on the arc-shaped support frame 1, thereby facilitating an operator to adjust the auxiliary positioning member 3 to a target position.

[0040] A positioning earplug 5 with a developing function is arranged on the inner side of the main positioning member 2, and both the main positioning member 2 and the auxiliary positioning member 3 can emit red light.

[0041] Specifically, the positioning earplug 5 contains a barium sulfate filling material, which can be developed under the irradiation of CT and C-arm. When in use, the locator is set on the patient's brain, and the positioning earplug 5 is inserted into the patient's ear, so as to realize the positioning of the main positioning member 2, and the patient is irradiated by CT or C-arm. In the image obtained by CT irradiation and development, the trigeminal nerve at the lesion site of the patient shows a point-shaped high-density image, so as to obtain the position parameters of the trigeminal nerve at the lesion site of the patient; the bottom of the main positioning member 2 can emit oblique red line light, and by adjusting the optical path of the red line light (see Example 2 for the adjustment of the optical path), the red line light is irradiated from the patient's ear to the nasolabial groove, and the oblique red line light forms a first indicator line 11 on the patient's face;

[0042] The position of the auxiliary positioning member 3 is adjusted so that it is located above the patient's pupil. When the longitudinal red line light emitted by the auxiliary positioning member 3 is directly facing the patient's pupil, the position of the auxiliary positioning member 3 is determined, and a second indicator line 12 is formed on the patient's face.

[0043] The first indicator line 11 and the second indicator line 12 meet to form an intersection, which is the puncture point. The puncture needle passes through the point and enters the site where the trigeminal nerve exits the cranial cavity: the oval foramen.

[0044] In this embodiment, by setting the positioning earplug 5 to cooperate with the CT or C-arm for imaging positioning, by adjusting the position of the auxiliary positioning member 3 to move it to the target position, the positioning of the auxiliary positioning member 3 is realized, and the puncture point is located by the red line light emitted by the positioned main positioning member 2 and the auxiliary positioning member 3. Compared with the traditional method of locating the puncture point by drawing a line, the present application only needs to change the position of the main positioning member 2 and the auxiliary positioning member 3 to realize the optical path adjustment of the red line light, which is simple and fast to operate and the positioning time is short.

[0045] Embodiment 2:

[0046] See also Figure 2 , based on the first embodiment, further and optionally, the main positioning member 2 includes a telescopic rod 4, a fixing member 41 and a projector 6 for emitting red light;

[0047] One end of the telescopic rod 4 is fixedly connected to the fixing piece 41 , and the other end is movably connected to the arc-shaped support frame 1 . The middle part of the fixing piece 41 is hinged to the projector 6 .

[0048] Specifically, the adjustment of the red line light path is as follows: since the fixing member 41 is hinged to the projector 6, the projector 6 can rotate in the vertical direction. The projector 6 is rotated to move forward or backward on the side face of the patient, thereby driving the red line light trajectory to change, thereby achieving the adjustment of the red line light path.

[0049] See also Figure 3 and Figure 4The arc-shaped support frame 1 is provided with a telescopic slot 7 for allowing the telescopic rod 4 to pass through, and a plurality of card slots 8 are arranged at intervals in the telescopic slot 7.

[0050] The telescopic rod 4 is provided with an elastic protrusion 9 which matches with the slot 8 .

[0051] The positioning earplug 5 is made of a developable material.

[0052] Specifically, when the size of the locator needs to be changed, the arc-shaped support frame 1 can be pulled up or pushed down to make the telescopic rod 4 and the telescopic slot 7 move relative to each other. When the telescopic rod 4 slides in the telescopic slot 7, the elastic protrusion 9 abuts against the side wall of the telescopic slot 7 and is in a contracted state. When the elastic protrusion 9 slides into the card slot 8, it will immediately expand and be stuck in the card slot 8, thereby realizing the size adjustment of the locator to adapt to the brain size of different patients; in addition, by reducing the spacing between the card slots 8 and increasing the number of the card slots 8, the adjustment accuracy can be improved.

[0053] See also Figure 2 , based on the first embodiment, further and optionally, the auxiliary positioning member 3 includes a slider 10 and a red line light;

[0054] The slide block 10 is passed through the arc-shaped support frame 1 , and the red line light is fixed on the slide block 10 .

[0055] The sliding block 10 is provided with screw holes for installing screws, and the screws abut against the arc-shaped support frame 1 through the screw holes.

[0056] Specifically, adjust the position of the slider 10 so that it is located above the patient's pupil. When the longitudinal red line light emitted by the red line light lamp on the slider 10 is directly facing the patient's pupil, tighten the screw to make it abut against the arc support frame 1, so as to fix the slider 10, thereby fixing the optical path of the second indicator line 12 and improving the positioning accuracy.

[0057] In summary, the present application sets a positioning earplug 5 to cooperate with CT or C-arm for imaging positioning, adjusts the position of the auxiliary positioning member 3 to move it to the target position, realizes the positioning of the auxiliary positioning member 3, and locates the puncture point through the red line light emitted by the positioned main positioning member 2 and the auxiliary positioning member 3. Compared with the traditional method of drawing lines to locate the puncture point, the present application only needs to change the position of the main positioning member 2 and the auxiliary positioning member 3 to achieve the optical path adjustment of the red line light, which is simple and fast to operate and has a short positioning time; the present application pulls up or pushes down the arc support frame 1 to make the telescopic rod 4 and the telescopic slot 7 move relative to each other. When the telescopic rod 4 slides in the telescopic slot 7, the elastic protrusion 9 abuts against the side wall of the telescopic slot 7 in a contracted state. When the elastic protrusion 9 slides into the card slot 8, it will immediately relax and be stuck in the card slot 8, thereby realizing the size adjustment of the locator, so as to adapt to the brain size of different patients; the present application tightens the screw to make it abut against the arc support frame 1, thereby realizing the fixation of the slider 10, thereby fixing the optical path of the second indicator line 12 and improving the positioning accuracy.

[0058] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it.
