Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a preoperative localization and puncture kit for pulmonary nodules and its method of use. Background Technology

[0002] The preoperative lung nodule localization puncture kit is a minimally invasive tool used to accurately mark the location of lung nodules before thoracoscopic surgery. The marker is implanted through CT-guided puncture, providing a reliable reference for rapid intraoperative localization.

[0003] Traditional positioning structures typically use metal anchor pins for surgical positioning. During use, the operator inserts the metal anchor pin through a needle and guides it to the target location. However, in practical applications, the smooth surface of the metal reduces tissue adhesion and increases the risk of unstable fixation. This can lead to an increased risk of pneumothorax / bleeding due to displacement, and the needle-like object can also cause the fixation to shift within the body as the person moves.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides, for example Figure 1-6 Shown: Example 1: A preoperative localization and puncture kit for lung nodules, comprising: The developing absorption auxiliary component 1 includes a first auxiliary structure 101, a second auxiliary structure 102 is provided on one side of the first auxiliary structure 101, and a third auxiliary structure 103 is provided on one side of the second auxiliary structure 102. The riveting assembly 2 is disposed in the middle of the developing and absorbing auxiliary assembly 1. The riveting assembly 2 is used to form the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103 into a triangular shape. The puncture component 3 is disposed on one side of the anchoring component 2 and is used to move the position of the imaging absorption auxiliary component 1.

[0025] It should be noted that the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 are all identical in shape and material, and are all made of absorbable and radiopaque material, achieving integrated positioning, resection, and degradation, thus avoiding the risk of secondary surgery in case of positioning failure or changes in the condition. In use, the riveting component 2 is first connected to the radiopaque and absorbable auxiliary component 1. After the radiopaque and absorbable auxiliary component 1 is moved to the required position by the puncture component 3, the riveting component 2 forms the radiopaque and absorbable auxiliary component 1 into a triangular shape. The triangular shape is designed with multiple support points to improve the anti-displacement performance.

[0026] Specifically, the riveting assembly 2 includes a riveting positioning line 201. The first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103 are all provided with through holes in the middle. The riveting positioning line 201 is inserted and connected inside the through hole. One end of the riveting positioning line 201 is provided with a positioning coil 202. The positioning coil 202 is sleeved in the middle of the positioning coil 202.

[0027] It should be noted that the through hole is adapted to the rivet positioning line 201, so that when the rivet positioning line 201 is inserted into the positioning coil 202, the inner wall of the positioning coil 202 presses against the rivet positioning line 201, preventing it from moving automatically. This allows the rivet positioning line 201 to pass through the through hole to the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103. The diameter of the through hole is smaller than the width of the positioning coil 202, preventing the positioning coil 202 from passing through the through hole to the first auxiliary structure 101. Therefore, after the rivet positioning line 201 passes through the first auxiliary structure 101, one end of the rivet positioning line 201 is blocked by the positioning coil 202, preventing it from fully penetrating the first auxiliary structure 101. The position of one end of the rivet positioning line 201 is restricted; the positioning coil 202 is set at one end of the rivet positioning line 201 and is directly formed by wrapping around the rivet positioning line 201. Through this design, a circular positioning coil 202 is formed at one end of the rivet positioning line 201. When it is necessary to fix the position of the developing absorption auxiliary component 1, the rivet positioning line 201 is first passed through the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103, and the end of the rivet positioning line 201 away from the positioning coil 202 is passed through the rivet positioning line 201. The first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103 are restricted on the rivet positioning line 201 by the rivet positioning line 201 and the positioning coil 202.

[0028] Specifically, the puncture assembly 3 includes a metal push rod 301 disposed on one side of the imaging absorption auxiliary assembly 1, a riveting assembly 2 inserted into the middle of the metal push rod 301, a metal puncture needle 302 sleeved on the outer wall of the metal push rod 301, the imaging absorption auxiliary assembly 1 inserted into the inside of the metal puncture needle 302, and a metal push block 303 fixedly connected to one side of the metal push rod 301, the metal push block 303 being used to move the position of the metal push rod 301.

[0029] It should be noted that the metal puncture needle 302 has a rigid and sharp tip, which can effectively reduce tissue damage and ensure the accuracy and controllability of the puncture process. During use, the operator first inserts the metal puncture needle 302 into the patient's skin and advances it along a predetermined path until the tip of the needle reaches the target position. An insertion hole is also provided in the middle of the metal puncture needle 302 to accommodate the metal push rod 301, ensuring that the metal push rod 301 can smoothly enter the metal puncture needle 302 while maintaining a stable fit to prevent shaking or displacement during operation. The metal push block 303 is cylindrical, with a diameter larger than the diameter of the insertion hole, preventing the metal push block 303 from entering the insertion hole. This design limits the insertion of the metal push block. The moving distance of the push rod 301 is specified. A hole is provided in the middle of the metal push rod 301. The diameter of the hole is larger than the diameter of the rivet positioning line 201, but less than twice the diameter of the rivet positioning line 201. This allows the rivet positioning line 201 to pass through the metal push rod 301, while the positioning coil 202 cannot pass through it. This design ensures the stability and controllability of the rivet positioning line 201 during operation, avoiding the impact on surgical precision due to the arbitrary movement of the rivet positioning line 201. Secondly, by restricting the passage of the positioning coil 202, this design can form a reliable mechanical block when the rivet positioning line 201 is pulled, ensuring that the positioning coil 202 always stays in the predetermined position, thereby achieving precise fixation of the implant.

[0030] Specifically, the material of the imaging absorption accessory component 1 is a material or polymer that is absorbable by the human body and can be visualized under X-ray, such as absorbable microcapsules containing contrast agent, and the anchoring positioning line 201 is an absorbable surgical suture.

[0031] It should be noted that the absorbable surgical sutures used are surgical sutures made of biodegradable materials that can be gradually hydrolyzed or enzymatically absorbed in the body, eliminating the need for suture removal. Their absorption time ranges from several weeks to several months. Depending on the material and weaving process, they can be divided into single-strand and multi-strand types. They provide necessary wound support while reducing foreign body residue and infection risks, promoting natural tissue healing. The absorbable polymers used are selected from, but are not limited to, PLA, PGA, PCL, PLGA, and their copolymers.

[0032] Example 2: A method for using a preoperative lung nodule localization and puncture kit, comprising the above-mentioned preoperative lung nodule localization and puncture kit, and the method of use includes the following steps: S1, Removal of the kit: Remove the imaging absorption accessory 1, the anchoring assembly 2, and the puncture assembly 3, and place them in the desired positions; S2, Assembly of the kit: Manually assemble the developing absorption accessory component 1, the riveting component 2, and the puncture component 3; S3, the kit is punctured into the required position, and the puncture component 3 drives the imaging absorption accessory component 1 and the anchoring component 2 to be inserted into the lung tissue; S4, Fixing the developing absorption accessory component 1: The developing absorption accessory component 1 is fixed in the required position by the combined use of the riveting component 2 and the puncture component 3. S5, work completion, manually pull the puncture component 3 out of the body and process the rivet positioning line 201.

[0033] Specifically, assembling the kit in S2 involves the following steps: S201, Assembly between the developing absorption auxiliary component 1 and the riveting component 2, the riveting positioning line 201 is passed through the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103 in sequence, and the positioning coil 202 is reserved on one side of the first auxiliary structure 101. Finally, the riveting positioning line 201 is passed through the middle of the positioning coil 202 and the riveting positioning line 201 is pulled so that the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103 are on the same horizontal line; S202, Installation of puncture assembly 3: The metal push rod 301 is sleeved on the middle of the riveting assembly 2, and the imaging absorption auxiliary assembly 1, the riveting assembly 2 and the metal push rod 301 are sequentially inserted into the interior of the metal puncture needle 302.

[0034] Specifically, the fixation of the developing absorption auxiliary component 1 in S4 includes the following steps: S401, Remove the developing absorption accessory component 1 and push it out of the metal puncture needle 302 by the push of the metal push rod 301; S402, adjust the shape formed by the developing and absorbing auxiliary component 1, and by pulling the rivet positioning line 201, drive the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103 to change their positions, so that the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103 on the same horizontal line form a triangle.

[0035] It should be noted that a riveting positioning line 201 with a positioning coil 202 is used to form an adjustable linkage structure by passing the end of the riveting positioning line 201 away from the positioning coil 202 through the first auxiliary structure 101, the second auxiliary structure 102, the third auxiliary structure 103, and the positioning coil 202 in sequence. When the free end of the riveting positioning line 201 is pulled, the tension of the riveting positioning line 201 will drive the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 to move closer to the center. At the same time, the constraint of the positioning coil 202 ensures that the relative positions of the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 are fixed, so that the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 automatically arrange themselves into a stable triangular structure. Its principle is based on tension balance and geometric constraints in mechanics: the tension of the anchoring positioning line 201 is evenly distributed among the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103, while the positioning coil 202 cannot pass through the metal push rod 301 and the first auxiliary structure 101, thus making the positioning coil 202 a fixed point. The fixed point restricts the movement direction of the first auxiliary structure 101, the second auxiliary structure 102 and the third auxiliary structure 103, forcing them to support each other at a 120-degree angle, thus forming a triangle with self-stabilizing characteristics.

[0036] Specifically, the work completion process in S5 includes the following steps: S501, the puncture component 3 is pulled out of the body by the metal puncture needle 302 driving the metal push rod 301 together, leaving the anchoring positioning line 201 and its end imaging absorption accessory component 1 in the lung tissue. S502, shortening of the anchoring positioning line 201: the anchoring positioning line 201 is exposed to the outside of the body or shortened along the skin surface using a scalpel.

[0037] It should be noted that the diameter of the metal push block 303 is larger than the diameter of the insertion hole on the metal puncture needle 302, making it impossible for the metal push block 303 to pass through the insertion hole. When the metal puncture needle 302 is pulled out, the metal push block 303 is moved by the metal puncture needle 302, and the metal push rod 301 is moved by the metal push block 303, so that the metal push rod 301 is pulled out directly when the metal puncture needle 302 is pulled out. When the rivet positioning line 201 is pulled out, the exposed part of the rivet positioning line 201 will increase. In order to prevent the exposed rivet positioning line 201 from being pulled out by non-medical personnel, it can be directly exposed outside the body with surgical scissors or cut short along the skin surface.

[0038] Furthermore, in actual use, the end of the riveting positioning line 201 away from the positioning coil 202 is first passed through the through holes opened in the middle of the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 in sequence. Then, the end of the riveting positioning line 201 away from the positioning coil 202 is passed through the positioning coil 202. This structure restricts the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 to the riveting positioning line 201. Next, the riveting positioning line 201 away from the positioning coil 202 is passed through the middle of the metal push rod 301 and the metal push block 303. The side of the metal push rod 301 away from the metal push block 303 is moved to the side of the positioning coil 202. Finally, the metal push rod 301, the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 are all inserted into the metal piercing. The needle 302 is inserted into the interior, and the third auxiliary structure 103 does not exceed the tip of the metal puncture needle 302. When in use, the metal puncture needle 302 is inserted to the desired position through the tip. The first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 are pushed out of the metal puncture needle 302 by the metal push rod 301. Then, the rivet positioning line 201 is pulled, which drives the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 to move, so that the first auxiliary structure 101, the second auxiliary structure 102, and the third auxiliary structure 103 form a triangular structure. Then, the metal puncture needle 302 is pulled out, which drives the metal push block 303 and the metal push rod 301 to be pulled out from their original positions. Finally, the rivet positioning line 201 is exposed outside the body or cut short along the skin surface by surgical scissors.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
