Description

Technical Field

[0001] The present invention belongs to the technical field of thyroid, and in particular relates to a system for enucleating necrotic lesions after thermal ablation treatment of large thyroid nodules. Background Art

[0002] Patients with benign large thyroid nodules (maximum diameter ≥ 40 mm) have neck compression symptoms and cosmetic problems. The traditional treatment method is surgical resection, but the trauma of surgical resection is relatively large, leaving scars on the neck, and there are still cosmetic problems. In recent years, thermal ablation (microwave ablation or radiofrequency ablation) technology has become an alternative treatment method for benign large thyroid nodules, with the advantages of small trauma, no scars, and quick recovery. However, after the ablation treatment of patients with benign large thyroid nodules, although the further growth of the lesions is controlled, the absorption and shrinkage process of the necrotic lesions is very slow, and the compression symptoms and cosmetic problems of some patients are not completely solved.

[0003] The thermal ablation treatment technology for patients with benign large thyroid nodules is mature. Its ablation electrode and technology cost are relatively high, but it can control and solve the further growth on the basis of minimally invasive treatment, and make some nodules shrink satisfactorily after treatment. However, there are still some benign large nodules that do not shrink satisfactorily after ablation treatment.

[0004] Therefore, we propose a system for enucleating necrotic lesions after thermal ablation treatment of large thyroid nodules to solve the above problems. Summary of the Invention

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A system for enucleating necrotic lesions after thermal ablation treatment of large thyroid nodules includes an operating rod, a drill rod, and an enucleating tube. The drill rod is fixed at the bottom of the operating rod, and the enucleating tube is arranged inside the drill rod. The inside of the drill rod is hollow, and a perforation is provided on the side of the drill rod. The enucleating tube passes through the inside of the drill rod and exits through the perforation. The inside of the operating rod is hollow, and a driving motor is fixedly connected to the top of the operating rod. The shaft of the driving motor extends into the inside of the operating rod, and the enucleating tube is connected to the shaft of the driving motor through the drill rod.

[0007] In the above system for enucleating necrotic lesions after thermal ablation treatment of large thyroid nodules, the bottom of the drill rod is in the shape of a sharp tip.

[0008] In the above system for enucleating necrotic lesions after thermal ablation treatment of large thyroid nodules, the perforation is arranged near the bottom edge of the drill rod, and the distance between the perforation and the bottom of the drill rod does not exceed 1.5 cm.

[0009] In the above-mentioned system for enucleating necrotic lesions after thermal ablation of large thyroid nodules, the enucleating tube includes a rotating head, a flexible tube, and an axially threaded wire. The rotating head is arranged at the end of the flexible tube and exposed. The rotating head is rotatably connected to the flexible tube. The axially threaded wire is fixedly connected to the rotating head. The flexible tube extends into the interior of the operating rod, and the connection between the flexible tube and the operating rod is threaded. An adjusting knob is sleeved on the flexible tube, and the adjusting knob is rotatably connected to the lower end of the operating rod. The axially threaded wire passes through the flexible tube and is fixedly connected to the shaft of the driving motor.

[0010] In the above-mentioned system for enucleating necrotic lesions after thermal ablation of large thyroid nodules, a telescopic rod is fixedly connected to the end of the axially threaded wire, and the end of the telescopic rod is fixedly connected to the shaft of the driving motor.

Detailed Embodiments

[0028] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0029] Embodiment 1

[0030] Patients with benign large thyroid nodules (maximum diameter ≥ 40 mm) have neck compression symptoms and cosmetic problems. In recent years, thermal ablation (microwave ablation or radiofrequency ablation) technology has become an optional treatment method for benign large thyroid nodules, with the advantages of minimal trauma, no scar, and quick recovery. Although it controls the further growth of the lesion, the absorption and shrinkage process of the necrotic lesion is very slow, and the compression symptoms and cosmetic problems of some patients have not been completely resolved. The thermal ablation treatment technology for patients with benign large thyroid nodules is mature, and its ablation electrode and technology cost are relatively high. However, it can control and solve the further growth on the basis of minimally invasive treatment, and make some nodules shrink satisfactorily after treatment. However, there are still some benign large nodules with unsatisfactory shrinkage after ablation treatment. Therefore, as Figures 1-8 shown, this scheme designs a system for excising necrotic lesions after thermal ablation of large thyroid nodules, including an operating rod 1, a drill rod 2, and an excision tube 3. Among them, the operating rod 1 is strip-shaped with a rounded edge for convenient holding. The operating rod 1 is used for medical staff to hold and operate by hand. The drill rod 2 is made of medical stainless steel. The drill rod 2 punctures into the lesion site that has been radiofrequency ablated, and re-punctures into the lesion position to facilitate the placement of the excision tube 3. The excision tube 3 needs to be placed into the lesion site through the drill rod 2, and the necrotic lesion is excavated little by little through the excision tube 3.

[0031] As Figures 1-3 shown, the drill rod 2 is fixed at the bottom of the operating rod 1, and the excision tube 3 is arranged inside the drill rod 2. The excision tube 3 is sent into the necrotic lesion through the drill rod 2. First, the drill rod 2 punctures to a specific position, and then the excision tube 3 is sent out.

[0032] As Figure 5 shown, in order to facilitate puncture, the bottom of the drill rod 2 is designed to be a sharp tip. The drill rod 2 can enter the patient's lesion in various ways. The inside of the drill rod 2 is hollow, and there is a perforation on the side of the drill rod 2. The drill rod 2 is cylindrical. The excision tube 3 passes through the inside of the drill rod 2 and is set out through the perforation. The perforation is circular, and the diameter of the perforation is the same as that of the excision tube 3. The excision tube 3 is stored inside the drill rod 2. The perforation is arc-shaped, and it turns to the side of the drill rod 2 through the arc of the drill rod 2. The perforation is arranged near the bottom edge of the drill rod 2, and the distance from the perforation to the bottom of the drill rod 2 does not exceed 1.5 cm to prevent excessive puncture of the drill rod 2.

[0033] As Figure 6As shown, the inside of the operating rod 1 is hollow and is used to accommodate the discharged residue of the lesion. In order to drive the operation of the enucleation tube 3, a driving motor 4 is fixedly connected to the top of the operating rod 1. The driving motor 4 is a servo driving motor with high rotational speed control accuracy. After the driving motor 4 is fixed, the shaft part of the driving motor 4 is extended into the inside of the operating rod 1, and the relevant contact parts are sealed. The enucleation tube 3 is connected to the shaft part of the driving motor 4 through the drill rod 2 as the power source for driving the enucleation tube 3 to perform enucleation operations. Specifically: The enucleation tube 3 includes a rotating head 5, a hose 6, and a shaft wire 7. Blades are installed on the end face of the rotating head 5. There are two blades, which are arranged symmetrically with an inclination center. The blades are inclined relative to each other to form a gap. The residue cut by the blades enters the inside of the hose 6 through the gap for collection purposes. The shaft wire 7 is a structure of stranded metal wires and has good rotational toughness. The overall shaft wire 7 has a flexible characteristic to ensure that it can still maintain a good rotational effect after bending. The hose 6 is made of rubber material, and a film layer for improving smoothness is coated on its surface. The film layer is made of hydrophobic material raw materials. The rotating head 5 is arranged at the end of the hose 6 and slightly protrudes, facilitating the blades to cut off the residue. The rotating head 5 and the end of the hose 6 are connected in a rotational manner. Therefore, the rotating head 5 can rotate at the end of the hose 6, and after rotation, the cutting purpose is achieved. The shaft wire 7 controls the rotation speed of the rotating head 5.

[0034] As Figure 4 shown, the rotating head 5 is arranged at the end of the hose 6 and protrudes. The rotating head 5 is rotatably connected to the hose 6. The shaft wire 7 is fixedly connected to the rotating head 5. The overall shaft wire 7 is arranged inside the hose 6 and is used for storage. The hose 6 extends into the inside of the operating rod 1, and the connection between the hose 6 and the operating rod 1 is threadedly connected. An adjustment knob 8 is sleeved on the hose 6. Therefore, the length of the hose 6 can be controlled by rotating the adjustment knob 8. As the adjustment knob 8 rotates, the hose 6 can freely extend and contract part of its length, thereby achieving the purposes of puncture and recovery. At the same time, during the removal process, the hose 6 needs to be continuously extended to control the progress and cutting direction of the rotating head 5. The drill rod 2 is rotatably connected to the bottom of the adjustment knob 8, and when the hose 6 is extended after puncture, it will achieve the effect of being within the clamping and fixing range.

[0035] The operating principle of the adjusting knob 8 is as follows: The adjusting knob 8 is rotatably connected to the lower end of the operating rod 1. An embedding groove 10 is provided on the hose 6, and a convex contact is provided on the inner wall of the adjusting knob 8. The adjusting knob 8 is mutually engaged with the embedding groove 10 through the convex contact. The shaft wire 7 passes through the hose 6 and is fixedly connected to the shaft part of the driving motor 4. One end of the shaft wire 7 is fixedly connected with a telescopic rod 9, and the end of the telescopic rod 9 is fixedly connected to the shaft part of the driving motor 4. Therefore, when the adjusting knob 8 is rotated, the hose 6 will move up and down under the action of the thread. During the moving process, the length of the hose 6 will be changed. Synchronously, there is also the shaft wire 7. The shaft wire 7 moves along with the hose 6 under the action of the telescopic rod 9, so as to complete the effect of rotational drive. In order to maintain the rotational force, the telescopic rod 9 is square-shaped. Therefore, the present invention can actively excise the ablated and necrotic lesion part, discharge the necrotic lesion part little by little, reduce the swelling sequela of the wound part, and achieve the effect of beauty and aesthetics.

[0036] Embodiment 2

[0037] In Embodiment 1, it is necessary to achieve a temporary storage effect through the hose 6, collect the cutting residues into the hose 6, and then send the residues into the operating rod 1 for temporary storage through extrusion. Therefore, the overly stacked hose 6 may affect the normal rotation of the shaft wire 7.

[0038] Therefore, as Figures 7-8 shown, an impeller group 11 is fixedly connected to the shaft part of the driving motor 4. The impeller group 11 is rotatably connected to the telescopic rod 9. During the driving rotation of the driving motor 4, the impeller group 11 is continuously used for suction, so that the residues inside the hose 6 can be quickly attracted into the operating rod 1. A plurality of small holes are opened at the top of the operating rod 1 to help the air flow. And a filter screen 15 is fixedly connected inside the operating rod 1 to prevent it from affecting the impeller group 11. At the same time, since the impeller group 11 needs a high rotation speed while the rotating head 5 does not need such a high rotation speed, a reduction gear group 12 is connected between the impeller group 11 and the telescopic rod 9 to form a speed difference, so that the rotating head 5 can maintain stable operation. In addition, a spiral plate 13 is provided on the shaft wire 7, and a plurality of through holes 14 are provided on the spiral plate 13. The through holes 14 are beneficial to the normal passage of air flow, and the spiral plate 13 can further drive the conveying of residues.

[0039] Although terms such as operating rod 1, drill rod 2, excision tube 3, driving motor 4, rotating head 5, hose 6, shaft wire 7, adjusting knob 8, telescopic rod 9, embedding groove 10, impeller group 11, reduction gear group 12, spiral plate 13, through hole 14, filter screen 15, etc. are used more in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
