Description

Technical Field

[0001] This utility model belongs to the field of thyroid tumors, and specifically relates to a puncture resection component suitable for thyroid tumors. Background Technology

[0002] The thyroid gland, the largest endocrine gland in the human body, is located beneath the thyroid cartilage, closely adjoining the anterior aspect of the third and fourth tracheal cartilage rings, and consists of two lobes and an isthmus. Accurate diagnosis and effective treatment of thyroid tumors have always been a key clinical focus. Thyroid cancer is one of the most common endocrine malignancies, and its incidence is on the rise globally. Early-stage thyroid cancer, if surgically removed promptly, usually has a good prognosis. However, some patients are diagnosed at a locally advanced stage, increasing the difficulty of treatment. For patients with thyroid tumors, precise removal of the tumor tissue, preserving the function of normal thyroid tissue to the greatest extent possible, while avoiding damage to surrounding important structures, is crucial for improving treatment outcomes and reducing complications. Therefore, optimizing thyroid tumor resection techniques is of paramount importance for patient survival and recovery.

[0003] In current technology, the most commonly used method for removing thyroid tumors is open neck surgery. Open neck surgery involves making an incision of a certain length in the front of the neck to expose the thyroid gland, and then precisely removing the thyroid tumor. However, although this method can directly and clearly expose the tumor, it leaves a noticeable scar on the patient's neck. In addition, postoperative complications such as neck pain, difficulty swallowing, and numbness of the neck skin are common. Utility Model Content

The two connecting rods are then rotatably connected to the drive rod. The drive rod extends and retracts, causing the first and second hemispherical shears to cut or open.

[0009] In this method, the puncture needle can precisely reach the location of the thyroid tumor tissue under ultrasound guidance. The resection mechanism then reaches the thyroid tumor tissue through the puncture channel inside the puncture needle and precisely removes the thyroid tumor tissue. The puncture and resection component disclosed in this method causes less trauma to the human body, avoiding the shortcomings of open neck surgery in existing technologies.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0026] Example

[0027] The basics are as follows: Figure 1 To be continued Figure 4 As shown, a puncture and resection assembly for thyroid tumors includes a puncture needle 1 and a resection mechanism 2. The puncture needle 1 is a metal needle with a puncture channel inside. The puncture needle 1 can be precisely moved to the location of the thyroid tumor under ultrasound guidance, and then the resection mechanism 2, which is located inside the puncture channel, can remove the thyroid tumor tissue.

[0028] The cutting mechanism 2 in this embodiment includes a first hemispherical shear 21, a second hemispherical shear 22, a driving structure 24, and a limiting structure.

[0029] In this embodiment, both the first hemispherical shear 21 and the second hemispherical shear 22 are hemispherical in shape, and their interiors are hollow. Both the first and second hemispherical shears 21 and 22 have inclined cutting surfaces at their edges. These cutting surfaces ensure better tumor tissue removal. The diameter of the first hemispherical shear 21 is larger than that of the second hemispherical shear 22, allowing the second hemispherical shear 22 to be accommodated within it. To avoid an excessively large gap between the two shears, the difference between the internal diameter of the first hemispherical shear 21 and the external diameter of the second hemispherical shear 22 is less than 0.2 cm. For example, when the internal diameter of the first hemispherical shear 21 is 1.5 cm, the external diameter of the second hemispherical shear 22 is 1.25 cm. As the second hemispherical shear 22 is accommodated within the first hemispherical shear 21, the two shears work together to remove the tumor tissue.

[0030] To secure the first hemispherical shears 21 and the second hemispherical shears 22, this embodiment includes a rectangular support rod 23 with a U-shaped notch at its front end. Both the first and second hemispherical shears 21 and 22 are housed within this U-shaped notch. A pivot is located at each end of the U-shaped notch, and both ends of the first and second hemispherical shears 21 and 22 are mounted on these pivots. The first and second hemispherical shears 21 and 22 can rotate around the pivot, allowing them to engage or disengage. When engaged, the first and second hemispherical shears 21 and 22 can work together to remove thyroid tumor tissue.

[0031] To ensure the fixed positions of the first hemispherical shear 21 and the second hemispherical shear 22, this embodiment provides a first positioning groove and a second positioning groove on the rotating shaft, respectively adapted to the first hemispherical shear 21 and the second hemispherical shear 22. The first hemispherical shear 21 has a rotating shaft hole, and the rotating shaft hole cooperates with the first positioning groove to limit the positioning, preventing the first hemispherical shear 21 from being misaligned during rotation. The second hemispherical shear 22 also has a rotating shaft hole, and this rotating shaft hole cooperates with the second positioning groove to limit the positioning, preventing the second hemispherical shear 22 from being misaligned during rotation.

[0032] To drive the first hemispherical shear 21 and the second hemispherical shear 22 to engage, the drive structure 24 of this embodiment includes a drive rod 241 and a connecting rod 242. Both the drive rod 241 and the connecting rod 242 are cylindrical rods. Two connecting members are provided, with the two connecting rods 242 respectively connected to the first hemispherical shear 21 and the second hemispherical shear 22 via rotating shafts. Simultaneously, the two connecting rods 242 are also connected to the drive rod 241, and the drive rod 241 and the connecting rod 242 are also rotatably connected via rotating shafts. The two connecting rods 242 and the drive rod 241 are arranged in a Y-shape. When the drive rod 241 extends or retracts, it drives the connecting rod 242 to rotate, and the connecting rod 242 then drives the first hemispherical shear 21 and the second hemispherical shear 22 to engage and disengage. To ensure that the drive rod 241 can be connected to the connecting rod 242 located inside the first hemispherical shear 21 and the second hemispherical shear 22, the first hemispherical shear 21 and the second hemispherical shear 22 are provided with a rectangular connection port. The drive rod 241 can extend from the connection port into the first hemispherical shear 21 and the second hemispherical shear 22, and is rotatably connected to the connecting rod 242 located inside the first hemispherical shear 21 and the second hemispherical shear 22. At the same time, in order to accommodate the drive rod 241, a receiving channel is constructed inside the support rod 23. The drive rod 241 is accommodated inside the receiving channel and can move telescopically within the receiving channel.

[0033] To achieve the telescopic movement of the drive rod 241, the tail end of the drive rod 241 can be connected to a related power mechanism. For example, the drive rod 241 can be connected to a linear motion module, and the linear motion module can drive the drive rod 241 to perform telescopic movement; or the drive rod 241 can be connected to a linear cylinder, and the linear cylinder can drive the drive rod 241 to perform telescopic movement.

[0034] To limit the range of motion of the drive rod 241, the limiting structure in this embodiment includes a limiting groove 251 and a limiting protrusion 252. The limiting groove 251 is a cylindrical groove disposed inside the receiving channel. The limiting protrusion 252 is annular and disposed on the drive rod 241. The limiting protrusion 252 is accommodated inside the limiting groove 251 and can extend and retract within the limiting groove 251. The limiting groove 251 restricts the range of motion of the limiting protrusion 252, thereby limiting the range of motion of the drive rod 241.

[0035] The following detailed description illustrates the specific implementation method: When thyroid tumor tissue needs to be removed, a puncture needle 1 is precisely inserted into the location of the thyroid tumor tissue under ultrasound guidance, with the puncture channel inside the puncture needle 1 extending to the thyroid tumor tissue. Then, the resection mechanism 2 is manually moved along the puncture channel inside the puncture needle 1, causing the tip of the resection mechanism 2 to extend from the puncture channel and contact the thyroid tumor tissue. The first hemispherical shears 21 and the second hemispherical shears 22 in the resection mechanism 2 are driven by a power structure to engage, thereby removing the thyroid tumor tissue. Simultaneously, since the first hemispherical shears 21 and the second hemispherical shears 22 are hollow, the removed thyroid tumor tissue is contained within the internal space of the first hemispherical shears 21 and the second hemispherical shears 22. Finally, as the resection mechanism 2 withdraws along the puncture channel, the thyroid tumor tissue is also removed.

[0036] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
