[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution: a lung nodule ablation auxiliary positioning device, including a mounting base 1. The mounting base 1 is a semi-circular structure with a flat bottom and an arc-shaped top surface. A groove 101 is provided at the bottom of the mounting base 1, and a chute 102 extending along the circumferential direction of the arc surface is opened on the top surface of the mounting base 1;

[0033] A sliding part 3 is slidably fitted in the chute 102. An adjusting rod 2 is connected to the sliding part 3. One end of the adjusting rod 2 extends towards the rear side of the mounting base 1, and an auxiliary sleeve 4 for placing a puncture needle is rotatably provided.

[0034] In this solution, during use, the patient lies flat in the groove 101, and the mounting base 1 is a semi-circular structure with an arc-shaped top surface. At this time, the patient lying flat in the groove 101 is the axis of the mounting base 1, so that the adjusting rod 2 moves around the patient.

[0035] During use, the position of the patient's lung nodule is detected in advance by CT. After observing the position of the lung nodule through the CT image, the patient lies flat, and the mounting base 1 is moved to place the patient's abdomen within the groove 101, and the auxiliary sleeve 4 is located above the patient's chest. At this time, according to the position of the lung nodule, the position of the auxiliary sleeve 4 is adjusted. By pulling the adjusting rod 2, it moves along the groove direction of the chute 102 through the sliding part 3 until the auxiliary sleeve 4 corresponds to the position of the lung nodule. Then, the auxiliary sleeve 4 is rotated to adjust the angle at which the puncture needle is inserted into the patient, thereby assisting medical staff in using the puncture needle and making it easier to master the puncture angle.

[0036] Among them, since the lungs are protected by the ribs, the device is provided with an arc-shaped chute 102 along the circumferential direction of the top surface of the mounting base 1, enabling the adjusting rod 2 and the auxiliary sleeve 4 to move around the patient's chest, facilitating the movement of the auxiliary sleeve 4 between two adjacent ribs. At this time, using the puncture needle can effectively reduce the positional conflict with the ribs and accurately puncture the lung nodule.

[0037] In this embodiment, the sliding part 3 includes an extension block 301 and a sliding plate 302. The sliding plate 302 is located within the chute 102. Limiting grooves 103 are provided on both side walls of the chute 102. Both sides of the sliding plate 302 are inserted into the two limiting grooves 103 respectively and are in sliding fit with the two limiting grooves 103.

[0038] The lower end of the extension block 301 is connected to the top surface of the sliding plate 302, and the upper end is connected to the adjusting rod 2.

[0039] Both ends of the sliding plate 302 are respectively inserted into the two limiting grooves 103, enabling it to move along the groove direction of the chute 102. At the same time, the extension block 301 is fixedly connected to the adjusting rod 2. Thus, when the sliding plate 302 moves, the extension block 301 and the adjusting rod 2 also move synchronously.

[0040] In this embodiment, it further includes a first screw rod 5. The lower end of the first screw rod 5 sequentially penetrates through the adjusting rod 2 and the extension block 301 from top to bottom and is rotatably connected to the top of the sliding plate 302. The first screw rod 5 is in threaded fit connection with the extension block 301.

[0041] A rubber pad 6 is fixedly installed on the upper side wall of the limiting groove 103.

[0042] In this solution, the inner wall of the extension block 301 is provided with a thread adapted to the first screw rod 5.

[0043] By rotating the first screw rod 5, the first screw rod 5 rotates along the thread inside the extension block 301. The first screw rod 5 moves up and down by rotating along the thread. When it is necessary to fix the position of the sliding plate 302, rotate the first screw rod 5 forward while it rotates and moves upward. Since the lower end of the first screw rod 5 is connected to the sliding plate 302 through a bearing, the sliding plate 302 moves upward synchronously with the first screw rod 5 until the sliding plate 302 squeezes the rubber pad 6 in the limit groove 103. By squeezing the rubber pad 6 with the sliding plate 302, the friction coefficient between the two is enhanced, and then the sliding plate 302 is difficult to slide in the sliding groove 102 through the frictional force.

[0044] In this embodiment, a scale line 7 is arranged along the outer edge of the top surface on the front side of the mounting seat 1. One end of the adjusting rod 2 extends towards the front side of the mounting seat 1, and an auxiliary rod 8 covering the scale line 7 is arranged. A visual window 801 for observing the scale line 7 is arranged on the auxiliary rod 8.

[0045] An angle scale 9 is arranged at one end of the adjusting rod 2 close to the auxiliary sleeve 4. One end of the auxiliary sleeve 4 is fixedly provided with a connecting rod 10 passing through the centers of the adjusting rod 2 and the angle scale 9, and a pointing rod 11 attached to one side of the angle scale 9 is connected.

[0046] During the process of the adjusting rod 2 sliding along the sliding groove 102, medical staff can directly observe the scale line 7 on the mounting seat 1 through the visual window 801 on the auxiliary rod 8, so as to observe the angles of the adjusting rod 2 and the auxiliary sleeve 4, and then determine the angle at which the puncture needle is inserted into the patient's lung; a movable rod and a suction cup are also arranged on one side of the auxiliary rod 8 close to the mounting seat 1. The movable rod is movably arranged on the auxiliary rod 8, and the suction cup is arranged at one end of the movable rod close to the mounting seat 1.

[0047] In this embodiment, a pressing plate 12 is arranged to lift and lower in the groove 101, and a soft pad 13 is arranged at the bottom of the pressing plate 12.

[0048] When the patient lies in the groove 101, the abdomen position of the patient is pressed by lowering the pressing plate 12 through the soft pad 13, reducing the movement range of the patient's body and making it not easy to generate jitter to affect the puncture needle.

[0049] Among them, the filling in the soft pad 13 is sponge or cotton, so that it is not easy to cause discomfort to the patient during the process of pressing the patient.

[0050] In this embodiment, a cavity 104 is arranged inside the mounting seat 1, a rotating shaft 14 is rotatably arranged inside the cavity 104, one end of the rotating shaft 14 extends outside the mounting seat 1, and is connected with a driving member 15;

[0051] A second screw 16 and a transmission member are further disposed in the cavity 104. The second screw 16 is in transmission connection with the rotating shaft 14 through the transmission member. One end of the second screw 16 penetrates downward through the cavity 104 and is rotatably connected to the top of the pressing plate 12.

[0052] Wherein, the second screw 16 is in threaded lifting connection with the transmission member.

[0053] When the medical staff rotates the driving member 15 to rotate the rotating shaft 14, the second screw 16 is driven to rotate through the transmission member. While the second screw 16 rotates, it moves downward, so that the pressing plate 12 installed with bearings at the lower end of the second screw 16 also moves synchronously, thereby pressing the abdomen of the patient.

[0054] In this embodiment, the second screw 16 is perpendicularly arranged to the rotating shaft 14. The transmission member includes two meshing bevel gears 17. One of the bevel gears 17 is threadedly sleeved on the second screw 16, and the other bevel gear 17 is fixedly sleeved on the rotating shaft 14.

[0055] Wherein, the rotating shaft 14 and the second screw 16 are respectively coaxial with the two bevel gears 17, and the second screw 16 is in threaded cooperation with one of the bevel gears 17;

[0056] During use, during the rotation of the rotating shaft 14, the second screw 16 is driven through the meshing of the two bevel gears 17, so that while rotating, it moves up and down along the internal thread on the bevel gear 17.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
