Abstract
Description
Technical Field
[0001] This invention relates to the field of medical assistive device technology, specifically to an ablation needle fixation bracket. Background Technology
[0002] In the field of minimally invasive tumor treatment, ablation therapy has become one of the commonly used clinical treatment methods due to its advantages of small trauma, rapid recovery, and clear efficacy. Its core is to accurately deliver energy to the lesion tissue through the ablation needle to achieve in situ inactivation of the lesion. The ablation needle fixation frame, as a key auxiliary device in ablation therapy, is mainly used to stabilize and position the ablation needle during the operation, avoiding the displacement of the ablation needle due to factors such as doctor's hand tremors, slight changes in patient position, or collision of surgical instruments, ensuring that the energy is accurately applied to the lesion and reducing damage to surrounding normal tissues.
[0003] In actual clinical practice, whether it is the ablation of solid tumors in the liver, lungs and breast, or the minimally invasive treatment of superficial lesions, the ablation needle fixation stent plays an important role in maintaining the spatial stability of the ablation needle and improving the safety and accuracy of the operation. It is one of the core auxiliary devices to ensure the effect of ablation treatment, and its performance directly affects the efficiency of the operation and the patient's treatment prognosis.
[0004] However, the adjustment mechanism of traditional ablation needle fixation stents is mostly manual spiral type, which can only achieve single adjustment in the up-down or left-right direction. It cannot achieve precise positioning at multiple angles according to surgical needs. When facing lesions that are deep and irregular in shape, it is difficult to meet the doctor's need for fine adjustment of the ablation needle angle. The existing solution has introduced a manual multi-dimensional adjustment stent, which can be freely bent and adjusted, avoiding the problem that the traditional single adjustment mechanism cannot adapt to the positioning of complex lesions. However, in actual operation, it is prone to loosening after long operation or slight external force, which further reduces the positioning stability. This not only prolongs the operation time, but also leads to incomplete ablation or damage to normal tissue due to positioning deviation, which is difficult to meet the clinical needs for high-precision and high-stability positioning. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an ablation needle fixation bracket, which solves the problem that existing ablation needle fixation brackets are prone to loosening after slight external force contact, thus reducing positioning stability.

[0008] Preferably, the disassembly mechanism includes a counterweight insertion seat, which is fixedly connected to the top of the first clamping plate. The top of the counterweight insertion seat has an insertion hole. The bottom end of the height adjustment rod is fixedly connected to an insertion block. A second sliding column is slidably connected to the right side of the counterweight insertion seat. The left end of the second sliding column passes through the right side of the counterweight insertion seat and is fixedly connected to a locking block. A second spring is fixedly connected to the outer wall of the second sliding column.
[0009] Preferably, the bottom of the vacuum cylinder passes through the top of the first clamping plate and is connected to the adsorption hole, and the outer wall of the sealing ring is slidably connected to the inner wall of the vacuum cylinder.
[0010] Preferably, a module is mounted on the right side of the fixture, and a threaded hole is provided on the right side of the module.
[0011] Preferably, an adjusting member is fixedly connected to the left end of the telescopic rod, and a threaded member is fixedly connected to the left end of the adjusting member, with the left end of the threaded member threadedly connected to the inside of the threaded hole.
[0012] Preferably, the outer wall of the height adjustment rod is threaded with a first reinforcing bolt, and the outer wall of the telescopic rod is threaded with a second reinforcing bolt.

[0014] Preferably, a hidden groove is provided on the bottom right side of the second clamping plate, and a hook is rotatably connected to the inner side of the hidden groove.
[0015] Preferably, a magnetic sheet is fixedly connected to the right side of the hook, and a recessed strip is provided on the top of the second clamping plate.
[0016] This invention provides an ablation needle fixation bracket. It has the following beneficial effects: 1. This invention allows the locking plate to disengage from the locking disc by pulling the sliding column, and then, after adjusting the telescopic rod, releasing the sliding column allows the locking plate to engage with the locking disc under the restoring force of the spring, thus completing the angle locking operation of the telescopic rod. When applied in surgical scenarios, this invention can effectively prevent the telescopic rod angle from shifting due to accidental contact, or the fixation effect from being affected by inaccurate angle.
[0017] 2. This invention uses a rotating stud to drive the oxygen extraction disc, thereby removing the air between the oxygen extraction disc and the fixed surface, and expelling the air from the top of the inner side of the vacuum cylinder through the air hole. This operation can improve the adsorption force and prevent the support from shaking due to insufficient clamping force.
[0018] 3. In this invention, when the plug block is placed into the plug hole, the locking block retracts inward under the pressure of the plug block. At this time, the plug block is fully inserted into the plug hole, and the locking block is re-locked into the slot on the plug block under the rebound action of the second spring, thus completing the preoperative rapid assembly work. This is not only more convenient and faster, but also saves the trouble of multiple people working together to assemble, thereby effectively improving surgical efficiency. Attached Figure Description

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.
[0022] Reference Figure 2 , Figure 4 and Figure 8 This invention provides an ablation needle fixation bracket, including a first clamping plate 1, a height adjusting rod 2 and a telescopic rod 3. A clamp 4 is provided at the left end of the telescopic rod 3, an adjusting mechanism 5 is provided at the top end of the height adjusting rod 2, the adjusting mechanism 5 is used to lock the angle of the telescopic rod 3, a reinforcing mechanism 6 is provided at the top of the first clamping plate 1, the reinforcing mechanism 6 is used to prevent shaking, and a disassembly mechanism 7 is provided at the bottom end of the height adjusting rod 2. The adjustment mechanism 5 includes a connector 501, which is fixedly connected to the top of the height adjustment rod 2. The connector 501 supports the adjustment mechanism 5. The height adjustment rod 2 can adjust the height of the fixed bracket according to actual needs to better adapt to the application environment. A connecting shaft 502 is rotatably connected to the top inner side of the connector 501. The front end of the connecting shaft 502 passes through the inner side of the connector 501 and is fixedly connected to a locking disc 503. The telescopic rod 3 and the connecting shaft 502 are integrally formed, allowing the telescopic rod 3 to rotate 180 degrees to adjust the direction of use. At the same time, the locking disc 503 and the connecting shaft 502 are also integrally formed. Multiple sets of slots are opened on the outer wall of the locking disc 503, which can lock the telescopic rod 3 precisely according to the required angle. A limit block 504 is fixedly connected to the front side of the connector 501. A sliding column 505 is slidably connected to the inner side of the limit block 504. A spring 506 is fixedly connected to the top of the outer wall of the sliding column 505. A lock plate 506 is fixedly connected to the top of the sliding column 505. The locking plate 507 has an inner center with a locking shape that matches the outer wall of the locking disc 503, enabling them to engage. When the sliding pin 505 is pulled, the spring 506 retracts inward, disengaging the locking plate 507 from the locking disc 503. At this point, the telescopic rod 3 can be adjusted to any angle. After releasing the sliding pin 505, the locking plate 507, under the return of the spring 506, engages with the locking disc 503, completing the angle locking. This is useful when applied in surgical settings. It can avoid accidental touch and inaccurate angle, which would affect the fixing effect; a module 11 is installed on the right side of the clamp 4, and a threaded hole 10 is opened on the right side of the module 11. The clamp 4 adopts the design of module 11, which can quickly process the clamp 4 according to the needs. An adjusting part 8 is fixedly connected to the left end of the telescopic rod 3. The adjusting part 8 can be bent at will and fine angle control can be performed, which greatly improves adaptability. A threaded part 9 is fixedly connected to the left end of the adjusting part 8, and the left end of the threaded part 9 is threaded to the inside of the threaded hole 10. Specifically, the connector 501 is fixed to the top of the height adjustment rod 2. The connector 501 primarily serves as a support and connection for the entire adjustment mechanism 5. The height adjustment rod 2 has flexible height adjustment capabilities, allowing for precise adjustment of the fixed bracket height according to specific usage needs, thus better adapting to various application environments and meeting diverse usage requirements. A connecting shaft 502 is installed on the inner top of the connector 501. The front end of the connecting shaft 502 penetrates the inner area of the connector 501, and a locking disc 503 is fixed to its front end. The telescopic rod 3 and the connecting shaft 502 are manufactured using an integrated molding process, enabling the telescopic rod 3 to rotate a wide range of 180 degrees, facilitating adjustment of its direction of use to adapt to different operational needs. The locking disc 503 and the connecting shaft 502 also have an integrated molding structure, with multiple sets of clips on the outer wall of the locking disc 503. The slots are designed to precisely lock the telescopic rod 3 according to the required fine angle. A limiting block 504 is fixed to the front of the connector 501. The limiting block 504 is used to limit the sliding of the sliding column 505. A spring 506 is installed between the sliding column 505 and the locking plate 507. At the same time, the inner middle of the locking plate 507 is provided with a locking structure that is completely consistent with the shape of the outer wall of the locking disc 503. This design can ensure that the two can lock together. The clamp 4 adopts the modular design of 11, which can be quickly and conveniently processed according to actual needs, greatly improving the flexibility and efficiency of use. An adjusting component 8 is fixedly connected to the left end of the telescopic rod 3. This adjusting component 8 has the ability to bend at will and can perform very fine angle control operations. This feature greatly improves the adaptability of the entire device, enabling it to better meet the needs of use in various complex scenarios.
[0023] Reference Figure 2 , Figure 5 and Figure 6The reinforcement mechanism 6 includes a rubber pad 601, which is fixedly connected to the bottom of the first clamping plate 1. The function of the rubber pad 601 is to better fit the fixing surface. Two adsorption holes 602 are opened at the bottom of the rubber pad 601, located on both sides of the bottom. Two vacuum cylinders 603 are connected to the top of the first clamping plate 1. The vacuum cylinders 603 are interconnected with the adsorption holes 602. A stud 604 is threadedly connected to the top of each vacuum cylinder 603. The bottom end of each stud 604 passes through the top of the vacuum cylinder 603 and is rotatably connected to an oxygen extraction disc 605. The bottom end of the stud 604 passes through the vacuum cylinder 603 and is installed and connected to the oxygen extraction disc 605. A sealing ring 606 is fixedly connected to the outer wall of the oxygen extraction disc 605. The sealing ring 606 can improve... The contact area between the oxygen pumping disc 605 and the vacuum cylinder 603 is such that the top of the vacuum cylinder 603 has two air holes 607. When the rotating stud 604 drives the oxygen pumping disc 605 to slide upward, it will draw away the air between the oxygen pumping disc 605 and the fixed surface, thereby improving the adsorption force. At the same time, the air at the top is discharged through the air holes 607. The bottom of the vacuum cylinder 603 passes through the top of the first clamping plate 1 and is connected to the adsorption hole 602. This can avoid insufficient clamping force and the bracket shaking. The outer wall of the sealing ring 606 is slidably connected to the inner wall of the vacuum cylinder 603. The bottom of the first clamping plate 1 is rotatably connected to the torsion shaft 14, and the bottom of the torsion shaft 14 is rotatably connected to the second clamping plate 15. The first clamping plate 1 and the second clamping plate 15 are pressed against each other, and the clamping is achieved by the torsion shaft 14. Specifically, the rubber pad 601 is connected to the bottom of the first clamping plate 1. The function of the rubber pad 601 is to better fit the fixed surface. The adsorption holes 602 are set on both sides of the bottom of the rubber pad 601. The vacuum cylinder 603 and the adsorption holes 602 are interconnected. The bottom end of the stud 604 passes through the vacuum cylinder 603 and is installed and connected to the oxygen pumping plate 605. The outer wall of the oxygen pumping plate 605 is fixed with a sealing ring 606. The sealing ring 606 can increase the contact area between the oxygen pumping plate 605 and the vacuum cylinder 603. The top of the vacuum cylinder 603 has two air holes 607, through which excess air is discharged. The bottom of the first clamping plate 1 is rotatably connected to the torsion shaft 14, and the bottom of the torsion shaft 14 is rotatably connected to the second clamping plate 15. The first clamping plate 1 and the second clamping plate 15 are pressed against each other, and the clamping operation is achieved by means of the torsion shaft 14.
[0024] Reference Figure 1 , Figure 3 and Figure 7The disassembly mechanism 7 includes a counterweight connector 701, which is fixedly connected to the top of the first clamping plate 1. The counterweight connector 701 not only provides corresponding counterweight for the entire bracket, improving its stability, but also enables multi-specification assembly of the bracket, enhancing the convenience of installation and storage. The top of the counterweight connector 701 has a connector hole 702, and the bottom end of the height adjustment rod 2 is fixedly connected to a connector block 703. The height adjustment rod 2 and the connector block 703 are integrally formed. The connector block 703 is square and matches the connector hole 702. This shape design also achieves a limiting effect. A sliding contact is slidably connected to the right side of the counterweight connector 701. The left end of the sliding column 705 passes through the right side of the counterweight insertion base 701 and is fixedly connected to the locking block 704. The outer wall of the sliding column 705 is fixedly connected to the spring 706. When the insertion block 703 is inserted inward, the locking block 704 and the spring 706 are squeezed and retracted inward. When the insertion block 703 is fully inserted into the insertion hole 702, the locking block 704 will spring back and lock into the slot on the insertion block 703, completing the rapid preoperative assembly. This is not only more convenient, but also saves the assembly of multiple people and improves surgical efficiency. Subsequently, by pulling the sliding column 705, the locking block 704 is disengaged from the slot on the insertion block 703, and disassembly is achieved. Specifically, the counterweight connector 701 is fixed to the top of the first clamping plate 1. The counterweight connector 701 provides necessary counterweight to the entire support, greatly improving its stability during use and preventing tipping due to external forces or structural problems. Furthermore, it allows for multi-specification assembly of the support, greatly simplifying installation and operation. It also saves space during storage, making storage and transportation easier. A connector hole 702 is provided at the top of the counterweight connector 701, and a connector block 703 is fixed to the bottom of the height adjustment rod 2. Furthermore, the height adjustment rod 2 and the plug block 703 are integrally formed, which ensures a firm connection between the two. The plug block 703 is designed to be square, and this shape is compatible with the plug hole 702. It can play a good limiting role during insertion, preventing the plug block 703 from rotating or misaligning within the plug hole 702. In addition, a sliding column 2 705 is slidably connected to the right side of the counterweight plug seat 701. The left end of the sliding column 2 705 passes through the right side of the counterweight plug seat 701 and is fixed with a locking block 704. A spring 2 706 is also fixedly connected to the outer wall of the sliding column 2 705. The bracket can be quickly assembled through the locking block 704.
[0025] Reference Figure 1 , Figure 2 and Figure 6The height adjustment rod 2 has a reinforcing bolt 12 threaded on the front side of its outer wall, and the telescopic rod 3 has a reinforcing bolt 23 threaded on the front side of its outer wall. The reinforcing bolt 12 and the reinforcing bolt 23 are used to adjust the telescopic length. The bottom right side of the second clamping plate 15 has a hidden groove 16. The inside of the hidden groove 16 is rotatably connected to a hook 17. The right side of the hook 17 is fixedly connected to a magnetic sheet 18. The top of the second clamping plate 15 has a recessed strip 19. The hook 17 can be stored and placed by the hook 17. When in use, it can be rotated and hidden in the hidden groove 16 and fixed by the magnetic sheet 18. Specifically, the height adjustment rod 2 and the telescopic rod 3 are equipped with reinforcing bolt 12 and reinforcing bolt 23, respectively. Their main function is to adjust the telescopic length to meet different usage needs. The bottom of the second clamping plate 15 is provided with a hidden groove 16. Inside this hidden groove 16, there is a hook 17 with a rotating connection. When in use, the hook 17 can rotate and be hidden in the hidden groove 16, and is fixed by adsorption through the magnetic piece 18 on its right side, thereby ensuring the stability and convenience of the hook 17 during use.
[0026] Working principle: When adjusting the angle of the telescopic rod 3, pulling the sliding column 505 will cause the spring 506 to retract inward, thereby causing the locking plate 507 to disengage from the locking disc 503. At this time, the telescopic rod 3 can be freely adjusted to any angle. When the user releases the sliding column 505, the locking plate 507 will re-engage with the locking disc 503 under the rebound force of the spring 506, thus completing the angle locking operation of the telescopic rod 3. By pressing the first clamping plate 1 and the second clamping plate 15, the clamping process is achieved with the help of the torsion shaft 14. The bottom of the vacuum cylinder 603 passes through the top of the first clamping plate 1 and is connected to the adsorption hole 602. When the stud 604 is rotated, it will drive the oxygen pumping plate 605 to slide upward. This process will remove the air between the oxygen pumping plate 605 and the fixed surface, thereby improving the adsorption force. The air at the top will be discharged through the air hole 607. This structural design can prevent the bracket from shaking due to insufficient clamping force. When the plug block 703 needs to be inserted inward, the locking block 704 and the second spring 706 will retract inward due to the pressure from the plug block 703. After the plug block 703 is fully inserted into the plug hole 702, the previously compressed locking block 704 will spring back under the action of the second spring 706 and lock into the pre-set slot on the plug block 703. When disassembly is required later, the locking block 704 can be disengaged from the slot on the plug block 703 by pulling the second sliding post 705, thus smoothly realizing the disassembly operation.
