Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to an auxiliary positioning device for a thyroid sampling probe. Background Technology
[0002] In the diagnosis of thyroid diseases, sampling and analysis of thyroid cysts is a crucial step in determining the nature of the cysts and developing a treatment plan. Traditional thyroid cyst sampling methods typically rely on the experience and feel of medical staff. During the procedure, the staff needs to hold an ultrasound probe in one hand to scan the patient's neck to pinpoint the exact location of the cyst, while simultaneously using the other hand to insert the sampling probe. This method has several inconveniences. First, the staff needs to simultaneously monitor both the ultrasound image display and the patient's neck position to ensure the sampling probe accurately punctures the cyst. Second, due to hand tremors, shifted vision, or lack of proficiency, the sampling probe is prone to deviation during insertion, leading to inaccurate sampling and potentially damaging surrounding healthy tissue, causing unnecessary pain and risks to the patient.
[0003] Therefore, there is an urgent market need for a device that can assist in locating thyroid sampling probes to improve sampling accuracy, reduce the workload of medical staff, and ensure patient safety. Utility Model Content
[0004] The purpose of this invention is to provide an auxiliary positioning device for a thyroid sampling probe, which is used to assist in the positioning of the sampling probe during thyroid cyst sampling, thereby improving sampling accuracy.

[0006] The base has a groove for supporting the patient's neck, and the base also has an arc-shaped groove that surrounds the outer ring of the groove.
[0007] An arc-shaped plate, wherein the arc-shaped plate is slidably disposed within the arc-shaped groove, and the end of the arc-shaped plate extends out from the arc-shaped groove, and the end of the arc-shaped plate is provided with a horizontal sliding groove;
[0008] A first adjustment part is disposed on the base and is used to adjust the extension and retraction of the arc-shaped plate;
[0009] A positioning platform, which is slidably mounted on a horizontal groove of the arc-shaped plate;
[0010] The second adjustment part is disposed at the end of the arc-shaped plate, and the second adjustment part is used to adjust the horizontal position of the positioning platform;
[0011] A positioning sleeve is fixed on the positioning platform. The diameter of the center hole of the positioning sleeve is the same as the outer diameter of the sampling probe, and the center hole of the positioning sleeve faces the groove.
[0012] In one embodiment, the first adjustment unit includes:
[0013] A rotating shaft, which is rotatably mounted on the base;
[0014] A gear is mounted on the rotating shaft, and a rack structure is provided on the surface of the arc-shaped plate, wherein the gear meshes with the rack structure;
[0015] A first adjusting handle is disposed on the rotating shaft.
[0016] In one embodiment, the second adjustment unit includes:
[0017] A lead screw is rotatably mounted on the arc-shaped plate. The length direction of the lead screw is parallel to the direction of the horizontal slide groove. A threaded hole is provided on the positioning platform, and the lead screw is threaded into the threaded hole of the positioning platform.

[0034] Please see Figures 1 to 4This application provides an auxiliary positioning device for a thyroid sampling probe, including a base 1, an arc-shaped plate 2, a first adjustment part 3, a positioning platform 4, a second adjustment part 5, and a positioning sleeve 6. The base 1 has a groove for supporting the patient's neck, and an arc-shaped groove 11 is also provided on the base 1, surrounding the outer edge of the groove. The arc-shaped plate 2 is slidably disposed within the arc-shaped groove 11, with its end extending out of the groove 11 and having a horizontal sliding groove 22 at its end. The first adjustment part 3 is disposed on the base 1 and is used to adjust the extension and retraction of the arc-shaped plate 2. The positioning platform 4 is slidably disposed on the horizontal sliding groove 22 of the arc-shaped plate 2. The second adjustment part 5 is disposed at the end of the arc-shaped plate 2 and is used to adjust the horizontal position of the positioning platform 4. The positioning sleeve 6 is fixed to the positioning platform 4, and the diameter of the central hole of the positioning sleeve 6 is the same as the outer diameter of the sampling probe, with the central hole of the positioning sleeve 6 facing the groove.
[0035] The auxiliary positioning device for thyroid sampling probe provided by this utility model is placed on the examination bed during thyroid examination. The patient lies flat on the examination bed with the patient's neck 10 resting in the groove of the base 1. Medical staff examine the thyroid gland by placing the ultrasound probe 9 close to the patient's neck 10. When a cyst is found in the patient's thyroid gland, the location of the cyst and the insertion position of the sampling probe are determined by the ultrasound probe 9. Then, the positioning sleeve 6 on the positioning platform 4 is aligned with the insertion position by the first adjustment part 3 and the second adjustment part 5. Then, medical staff can insert the sampling probe into the central hole of the positioning sleeve 6, and then insert it from the bottom of the positioning sleeve 6 into the cyst location of the patient's thyroid gland to sample and analyze the cyst tissue. Because the sampling probe is positioned by the positioning sleeve 6 during this process, it avoids deviation of the sampling probe due to hand tremors during the needle insertion process, ensuring that the sampling probe accurately pierces the cyst of the patient's thyroid gland. This solves the technical problem of traditional thyroid cyst sampling, where medical staff need to operate the ultrasound probe 9 with one hand and operate the sampling probe with the other hand, and need to observe the ultrasound image display screen in real time to determine the position of the sampling probe and the cyst, which makes it easy for the sampling probe to deviate during the needle insertion.
[0036] The specific adjustment process of the positioning sleeve 6 is as follows: the extension and retraction of the arc plate 2 can be adjusted by the first adjustment part 3. Since the arc plate 2 is slidably set in the arc groove 11, and the arc groove 11 is arranged around the outer ring of the groove of the base 1, and the patient's neck pillow rests on the groove of the base 1, the positioning platform 4 can be adjusted to move around the outer ring of the patient's neck 10 by the first adjustment part 3, and the positioning platform 4 can be adjusted to move along the horizontal slide groove 22 by the second adjustment part 5, so that the positioning sleeve 6 on the positioning platform 4 can move to any point above the patient's neck 10. After the location of the patient's cyst is known by the ultrasound probe 9 to confirm the needle insertion position, the positioning sleeve 6 can be adjusted to point to the needle insertion position by the first adjustment part 3 and the second adjustment part 5.
[0037] Furthermore, the angle between the positioning sleeve 6 and the end face of the arc plate 2 is the down-needle angle of the sampling probe. Therefore, the angle between the positioning sleeve 6 and the end face of the arc plate 2 can be designed according to the down-needle angle requirements of the sampling probe to ensure that the down-needle angle of the sampling probe meets the requirements after the sampling probe is assisted in positioning by the positioning sleeve 6.
[0038] In one embodiment, the first adjustment part 3 includes a rotating shaft 31, a gear 32, and a first adjustment handle 33. The rotating shaft 31 is rotatably mounted on the base 1. The gear 32 is mounted on the rotating shaft 31, and a rack structure 21 is provided on the surface of the arc-shaped plate 2, with the gear 32 meshing with the rack structure 21. The first adjustment handle 33 is mounted on the rotating shaft 31. During adjustment, simply turning the first adjustment handle 33 rotates the rotating shaft 31 and the gear 32 thereon, thereby driving the arc-shaped plate 2 to extend or retract.
[0039] In one embodiment, the second adjusting part 5 includes a lead screw 51 and a second adjusting handle 52. The lead screw 51 is rotatably mounted on the arc-shaped plate 2, and its length direction is parallel to the direction of the horizontal slide groove 22. A threaded hole is provided on the positioning platform 4, and the lead screw 51 is threaded into the threaded hole of the positioning platform 4. The second adjusting handle 52 is located at the end of the lead screw 51. The lead screw 51 and the positioning platform 4 form a lead screw 51 slider structure, such that when the second adjusting handle 52 is turned, the lead screw 51 rotates, simultaneously driving the positioning platform 4 to slide along the horizontal slide groove 22, thereby adjusting the position of the positioning sleeve 6 on the positioning platform 4.
[0040] like Figure 2 As shown, in one embodiment, a laser calibrator 7 is also included. The laser calibrator 7 is disposed at the bottom of the positioning sleeve 6, and the laser direction emitted by the laser calibrator 7 is parallel to the axis of the central hole of the positioning sleeve 6. The laser emitted by the laser calibrator 7 illuminates the patient's neck 10 below, and can play a positioning role when adjusting the positioning sleeve 6, so that medical staff can accurately and quickly adjust the positioning sleeve 6 into place.
[0041] In one embodiment, a padding layer 8 is provided on the surface of the groove, and the padding layer 8 is made of a flexible material. Specifically, the padding layer 8 can be made of materials such as sponge or cotton, and the padding layer 8 can improve the comfort of the patient's neck 10.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
