Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an adjustable thyroid puncture device with a rapid positioning function. Background Art

[0002] Thyroid puncture is commonly used for certain thyroid diseases that are still difficult to diagnose after multiple examinations. It is a routine examination method for goiter and thyroid nodular diseases. In the existing thyroid puncture method, a doctor holds a thin needle and inserts it into the lesion of the thyroid gland to extract a small amount of tissue, and then understands the nature of the cells through a microscope to make a diagnosis. When a doctor performs thyroid puncture with a thyroid puncture device, due to the shaking of the novice doctor's hand, the needle of the thyroid puncture device is likely to deviate in the thyroid gland, affecting the puncture accuracy of the thyroid puncture device, resulting in inaccurate substance adsorption, and multiple negative pressure operations are required. This requires a certain level of proficiency in the doctor's operation. At the same time, multiple puncture failures not only increase the operation time but also increase the puncture risk and discomfort.

[0003] Therefore, the Chinese patent with the publication number "CN118356217A" discloses "an adjustable thyroid puncture device with a rapid positioning function". Its main structure includes an operating bed, a position adjustment component, a positioning component, a smearing component, a puncture adjustment component, and an auxiliary support component; a positioning component for fixing the patient's neck to prevent involuntary rotation during thyroid puncture is installed at the upper end of the operating bed; a position adjustment component for adjusting the movement of the positioning component on the operating bed is installed at the lower end of the positioning component; a smearing component for quickly and evenly smearing and disinfecting the puncture area is arranged inside the positioning component; a puncture adjustment component for quickly and stably controlling the angle and position of the puncture instrument is fixedly connected to the upper end of the positioning component; an auxiliary support component for stably supporting the lower end of the doctor's elbow is installed on one side of the positioning component close to the edge of the operating bed.

[0004] The above-mentioned adjustable thyroid puncture device with a rapid positioning function stably supports the doctor's hands from below through the auxiliary support component to avoid involuntary hand shaking during the doctor's operation. The puncture target position on the neck can be quickly located through the puncture adjustment component, and then the positioned puncture needle is pressed multiple times, and the puncture needle is inserted into the puncture target position to complete the puncture sampling. However, the puncture needle can only slide along the periphery of the arc positioning frame, and due to the fixed connection method of the arc positioning frame, the puncture needle can only move in a longitudinal plane, so the movement angle of the puncture needle in the working state is relatively narrow.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 and Figure 2 , an adjustable thyroid puncture device with a fast positioning function, including two parallel arc positioning frames 1 and two main docking plates 2 fixedly installed at the bottom ends of the arc positioning frames 1. This device can be used in cooperation with a lifting device that can play a lifting role. When in use, fixedly connect the top end of the lifting rod of the lifting device to the bottom end of the bottom fixing plate 43.

[0024] In order to achieve an adjustable force positioning effect, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is necessary to set an adjustable limiting mechanism 3, which is internally provided with a puncture limiting bracket 31 that can limit the running route of the puncture needle, an arc-shaped sliding sleeve 35 arranged on both sides of the puncture limiting bracket 31 and capable of sliding along the arc positioning frame 1, and an arc-shaped elastic air film 38 installed inside the arc-shaped sliding sleeve 35 and capable of being wrapped and clamped on the outer surface of the arc positioning frame 1 after being subjected to gas pressure. Use an inflation device to inflate the outer layer area of the arc-shaped inner cavity 37 through the gas compensation channel 39 and control the pressure of the inflated gas. Under the action of the air pressure, the inner wall of the arc-shaped elastic air film 38 will be wrapped and clamped on the outer surface of the arc positioning frame 1. When it is necessary to move the arc positioning frame 1, apply a force to it. When the applied force is greater than the friction force between the arc-shaped elastic air film 38 and the arc positioning frame 1, the puncture limiting bracket 31, the upper limiting channel height 32, and the lower limiting channel 33 will move directionally. Through this principle, move the puncture limiting bracket 31, the upper limiting channel height 32, and the lower limiting channel 33 to the required positions. When puncture is required, insert the puncture needle through the puncture limiting hole 34 and complete the puncture.

[0025] For the specific structure of the adjustable limit mechanism 3, please refer to Figure 3 and Figure 4 , including a puncture limit bracket 31. An upper limit channel 32 and a lower limit channel 33 with an integral structure are respectively arranged on the upper arc end face and the lower arc end face of the puncture limit bracket 31. A puncture limit hole 34 for the puncture needle to penetrate is arranged inside the puncture limit bracket 31, the upper limit channel 32 and the lower limit channel 33. An arc-shaped sliding sleeve 35 with an integral structure is respectively arranged at both ends of the puncture limit bracket 31. An arc-shaped sliding hole 36 sleeving the periphery of the arc positioning frame 1 is arranged inside the arc-shaped sliding sleeve 35. An arc-shaped inner cavity 37 is arranged on the periphery of the middle region of the arc-shaped sliding hole 36 of the arc-shaped sliding sleeve 35. An arc-shaped elastic air film 38 located on the periphery of the arc positioning frame 1 is installed inside the arc-shaped inner cavity 37 of the arc-shaped sliding sleeve 35. A gas compensation channel 39 communicating the external space and the outer circumferential surface of the arc-shaped inner cavity 37 and with a gas valve installed inside is arranged on the outer circumferential surface of the arc-shaped sliding sleeve 35. The two end edges of the arc-shaped elastic air film 38 are hermetically embedded in the two end faces of the arc-shaped inner cavity 37. The arc-shaped elastic air film 38 divides the arc-shaped inner cavity 37 into a non-communicating inner region and an outer region. The arc positioning frame 1 is located in the inner region.

[0026] To increase the movement range of the puncture needle, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , two universal connection mechanisms 4 need to be set. Inside them, there are a hemispherical shell 41 with a hollow interior, a rotating ball head 45 installed inside the hemispherical shell 41 and capable of rotating, a braking rubber pad 46 capable of controlling the frictional resistance during the rotation of the rotating ball head 45 inside the hemispherical shell 41, and a top fixing plate 48 connected to the main docking plate 2 and capable of making the arc positioning frame 1 move with the rotating ball head 45. Medical staff can manually apply force to one side of the arc positioning frame 1, so that the arc positioning frame 1 rotates. At this time, the rotating ball head 45 will adaptively rotate inside the hemispherical shell 41. After the movement is completed, since the frictional force of the braking rubber pad 46 on the rotating ball head 45 is sufficient to keep the arc positioning frame 1 in a stable state when no external force is applied, therefore, the puncture limit bracket 31, the upper limit channel 32 and the lower limit channel 33 can be positioned at the required positions and angles, thereby increasing the movement range of the puncture needle.

[0027] For the specific structure of the universal connection mechanism 4, please refer to Figure 5 and Figure 6, including a hemispherical housing 41, a bottom fixing plate 43 integrally structured with the bottom of the hemispherical housing 41 is provided, a hemispherical cavity 42 with an open top is arranged inside the hemispherical housing 41, an inwardly concave mounting groove 44 is provided at the periphery of the hemispherical housing 41 at the bottom of the hemispherical cavity 42, a rotatable rotating ball head 45 is placed inside the hemispherical housing 41 within the hemispherical cavity 42, a braking rubber pad 46 with an inwardly concave surface abutting against the surface of the rotating ball head 45 is installed inside the inwardly concave mounting groove 44, an axial connecting rod 47 integrally structured with the top of the rotating ball head 45 is provided at the top of the rotating ball head 45, a top fixing plate 48 fixed to the bottom of the main docking plate 2 is installed at the top end of the axial connecting rod 47, the frictional force of the braking rubber pad 46 on the rotating ball head 45 is sufficient to keep the arc positioning frame 1 in a stable state when no external force is applied, the structural radius of the rotating ball head 45 matches the structural radius of the hemispherical cavity 42, and the diameter of the open end at the top of the hemispherical cavity 42 is smaller than the structural diameter of the rotating ball head 45.

[0028] During use, an inflation device is used to inflate the outer region of the arc-shaped inner cavity 37 through the gas compensation channel 39 and control the pressure of the inflated gas. Under the action of the air pressure, the inner wall of the arc-shaped elastic air film 38 will be wrapped around and clamped on the outer surface of the arc positioning frame 1. When it is necessary to move the arc positioning frame 1, a force is applied to it. When the applied force is greater than the frictional force between the arc-shaped elastic air film 38 and the arc positioning frame 1, the puncture limiting bracket 31, the upper limiting channel 32 and the lower limiting channel 33 will move directionally. Based on this principle, the puncture limiting bracket 31, the upper limiting channel 32 and the lower limiting channel 33 are moved to the required positions. The medical staff manually applies a force to one side of the arc positioning frame 1, thereby causing the arc positioning frame 1 to rotate. At this time, the rotating ball head 45 will adaptively rotate inside the hemispherical housing 41. After the movement is completed, since the frictional force of the braking rubber pad 46 on the rotating ball head 45 is sufficient to keep the arc positioning frame 1 in a stable state when no external force is applied, therefore, the puncture limiting bracket 31, the upper limiting channel 32 and the lower limiting channel 33 can be positioned at the required positions and angles. When puncture is required, the puncture needle is inserted through the puncture limiting hole 34 to complete the puncture.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
