Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a tumor interventional therapy device. Background Technology

[0002] A tumor is a new growth formed by the abnormal proliferation of local tissue cells under the influence of various tumorigenic factors. This new growth often manifests as a space-occupying, mass-like protrusion, hence it is also called a neoplasm. Based on the cellular biological characteristics of the new growth and its degree of harm to the body, tumors can be further divided into two major categories: benign tumors and malignant tumors. Interventional radiology, also known as interventional therapy, is a rapidly developing emerging discipline that integrates imaging diagnosis and clinical treatment. Its core is a series of techniques that, under the guidance and monitoring of imaging equipment such as digital subtraction angiography, CT, ultrasound, and MRI, use interventional instruments such as puncture needles and catheters to precisely insert specialized instruments into the lesion site through natural body orifices or tiny incisions to perform minimally invasive treatment.

[0003] In the clinical operation of microwave probe ablation, precise location of the puncture site is required first, followed by disinfection of the marked area. The operator holds the puncture instrument to pierce the skin, while simultaneously using imaging equipment to observe the puncture process in real time, ensuring that the puncture needle accurately penetrates the tumor tissue and providing assurance for subsequent treatment effects. However, the current mainstream clinical puncture method is still mainly manual operation by the operator. For hard tumors such as pancreatic cancer, some intrahepatic metastases of liver cancer, and scleroderma of the breast, these lesions are often solid, highly fibrotic, or accompanied by calcification, and their tissue density is significantly higher than that of normal soft tissue and ordinary tumor tissue. When manually holding the puncture needle to penetrate such lesions, a large pushing force is required to overcome the mechanical resistance of the tumor stroma. This operation process is prone to various problems: Firstly, the tip of the puncture needle is prone to bending, which can cause deviation of the puncture path and a significant reduction in puncture speed, affecting the subsequent tumor ablation effect. Secondly, excessive resistance may directly cause the puncture needle to break. Third, forced puncture can easily cause the tumor capsule to rupture, thereby increasing the risk of tumor cell spread; Fourth, if the puncture force decreases instantaneously, it may accidentally puncture normal tissue on the opposite side of the tumor, causing unnecessary damage. Therefore, a tumor interventional treatment device is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a tumor interventional therapy device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an alternative solution to the tumor interventional therapy device described in this invention, the tumor interventional therapy device includes a fine-tuning lifting mechanism, a rotary insertion module, a microwave probe, and an adaptive adjustment module. A rotary insertion module is installed on one side of the fine-tuning lifting mechanism. A microwave probe is installed inside the rotary insertion module. The rotary insertion module is used to drive the microwave probe to rotate to ensure that the tumor is punctured. A vertically set adaptive adjustment module is also fixedly connected to one side of the rotary insertion module, with one side of the adaptive adjustment module located on the outside of the microwave probe. The rotary insertion module includes a placement plate that is fixedly connected to the fine-tuning lifting mechanism. A rotating disk is installed inside the placement plate. A limiting sleeve is fixedly connected inside the rotating disk. A microwave probe is installed on the inner side of the limiting sleeve. The first forward and reverse motor is fixedly connected inside the placement plate. The main shaft of the first forward and reverse motor is fixedly connected to the end of the drive gear. The outer side of the drive gear meshes with the driven gear ring. The inner side of the driven gear ring is fixedly connected to the rotating disk. An adjusting sleeve is fixedly connected to the top of the rotating disk. A threaded shaft is screwed inside the adjusting sleeve. A second handle is fixedly connected to the top of the threaded shaft. An adjusting plate is rotatably connected to the outside of the threaded shaft. A lower pressure plate is rotatably connected to the bottom of the adjusting plate. A pressure sensing unit is installed at the bottom of the lower pressure plate. A control unit is fixedly connected to the top of the adjustment plate.

[0006] As an optional embodiment of the tumor interventional therapy device of the present invention, the driven gear ring is provided with limit rings on both the upper and lower sides. The inner side of the limit ring is fixedly connected to the rotating disk, and the outer side of the limit ring is rotatably connected to the placement plate.

[0007] As an optional embodiment of the tumor interventional therapy device of the present invention, a rotating block is rotatably connected to one side of the bottom of the rotating disk, a rotating rod is fixedly connected to one side of the rotating block, a connecting disk is fixedly connected to the other side of the rotating rod, and a laser lamp is fixedly connected to the bottom of the connecting disk.

[0008] In the clinical operation of microwave probe ablation, the puncture site must first be accurately located, followed by disinfection of the marked area. The operator holds the puncture instrument to puncture the skin, while simultaneously using imaging equipment to observe the puncture process in real time, ensuring that the puncture needle accurately enters the tumor tissue and providing assurance for the subsequent treatment effect. However, the current mainstream puncture method in clinical practice is still mainly manual operation by the operator. For hard tumors such as pancreatic cancer, some intrahepatic metastases of liver cancer, and scleroderma of the breast, these lesions are often solid, highly fibrotic, or accompanied by calcification. Their tissue density is significantly higher than that of normal soft tissue and ordinary tumor tissue. When manually holding the puncture needle to penetrate such lesions, a large pushing force is required to overcome the mechanical resistance of the tumor stroma. This operation process is prone to several problems: First, the puncture needle tip is prone to bending, leading to deviation of the puncture path and a significant slowdown in puncture speed, affecting the subsequent tumor ablation effect; second, excessive resistance may directly cause the puncture needle to break; third, strong resistance may cause the needle to break. Puncture can easily cause tumor capsule rupture, increasing the risk of tumor cell spread. Fourthly, if the puncture force weakens momentarily, it may accidentally puncture normal tissue on the opposite side of the tumor, causing unnecessary damage. This solution uses a rotating insertion module to fix the microwave probe. During puncture, the microwave probe is first placed in the rotating disk. By rotating the second handle, the threaded shaft and adjusting sleeve rotate synchronously. Simultaneously, the lower pressure plate is attached to one side of the microwave probe, and a pressure sensing unit is installed inside the lower pressure plate to monitor the upward reaction force on the microwave probe in real time. The operator manually adjusts the fine-tuning lifting mechanism to smoothly lower the rotating insertion module and microwave probe, achieving precise puncture of the lesion area, ensuring puncture quality and efficiency, and laying the foundation for subsequent tumor ablation. When the bottom of the microwave probe contacts hard tumor tissue, the squeezing force of the tumor tissue on the probe is transmitted to the pressure sensing unit, and the pressure data is fed back to the control unit in real time. The control unit compares the collected pressure value with a preset threshold. Once the pressure value exceeds the threshold, it is determined that the probe has contacted the tumor tissue. At this point, the first forward and reverse motors start and drive the drive gear to rotate. The drive gear meshes and drives the driven gear ring to rotate, which in turn drives the microwave probe to reciprocate. The rotational motion during the puncture process can effectively reduce puncture resistance, ensure that the probe is stably inserted into the lesion area, and at the same time avoid damage to the needle body due to excessive force, thus ensuring the structural integrity of the microwave probe.

[0009] As an optional embodiment of the tumor interventional therapy device described in this invention, the fine-tuning lifting mechanism includes a guide plate, an adjusting shaft is rotatably connected inside the guide plate, a first handle is fixedly connected to the top of the adjusting shaft, an adjusting block is spirally connected to the outside of the adjusting shaft, one side of the adjusting block is fixedly connected to the rotary insertion module, the outside of the adjusting block is slidably connected to the guide plate, and a connecting block is fixedly connected to one side of the guide plate.

[0010] As an optional embodiment of the tumor interventional therapy device described in this invention, a connecting arm is fixedly connected to one side of the connecting block, and a multi-angle adjustable base is connected to the other end of the connecting arm.

[0011] When performing microwave probe insertion into the skin, the first handle is rotated to drive the adjustment shaft to rotate, thereby causing the adjustment block to make fine adjustments up and down, which in turn causes the rotary insertion module to move smoothly, ensuring the puncture operation of the microwave probe.

[0012] As an optional solution of the tumor interventional treatment device of the present invention, the adaptive adjustment module includes a vertical plate fixedly connected to the rotary insertion module, a second forward and reverse motor is fixedly connected inside the vertical plate, a threaded rod is fixedly connected to the end of the main shaft of the second forward and reverse motor, and the other end of the threaded rod is rotatably connected to the vertical plate. A movable sleeve is helically connected to the outer side of the threaded rod. A support shaft is fixedly connected to one side of the movable sleeve. A reinforcement mechanism is fixedly connected to the other end of the support shaft. A microwave probe is provided on the inner side of the reinforcement mechanism. The outer side of the movable sleeve is slidably connected to the vertical plate.

[0013] As an optional embodiment of the tumor interventional therapy device of the present invention, the reinforcement mechanism includes a reinforcement ring fixedly connected to the support shaft. Multiple reinforcement rings are arranged and distributed vertically. A fixing rod is fixedly connected to one side of the uppermost reinforcement ring, and the other end of the fixing rod is fixedly connected to the vertical plate.

[0014] As an optional embodiment of the tumor interventional therapy device of the present invention, wherein: the upper surface of all the reinforcing rings below the reinforcing ring connected to the fixing rod is fixedly connected to a connecting column, and the other end of the connecting column is fixedly connected to a retaining ring; Guide grooves are provided on the surface of the reinforcing ring above the reinforcing ring connected to the support shaft.

[0015] As an optional embodiment of the tumor interventional therapy device described in this invention, the connecting columns above the multiple reinforcing rings are staggered. The number of guide grooves on the upper surface of the multiple reinforcing rings distributed vertically increases sequentially from bottom to top.

[0016] As an alternative embodiment of the tumor interventional therapy device described in this invention, a rangefinder is installed at the bottom of the lowest reinforcing ring.

[0017] As the microwave probe gradually penetrates the patient's body, the rotating insertion module drives the probe downwards synchronously, and the adaptive adjustment module moves downwards in tandem. The rangefinder on this module monitors the distance between the module and the skin in real time. When the rangefinder detects that the module is about to contact the skin, a control command triggers the second forward and reverse motors to rotate, driving the threaded rod to rotate. This, in turn, causes the moving sleeve, support shaft, and reinforcement mechanism to move synchronously, maintaining a safe distance between the reinforcement mechanism and the skin, preventing interference with the puncture path, and ensuring the puncture accuracy of the microwave probe. Furthermore, the reinforcement mechanism, fitted around the outside of the microwave probe needle, provides radial support, preventing bending deformation of the needle when puncturing hard tumors. As the needle gradually penetrates the body, the reinforcement rings of the reinforcement mechanism adaptively move closer and contract, neither hindering the puncture process nor hindering the gradual release of the needle, further improving puncture stability.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This solution incorporates a rotary insertion module to secure the microwave probe. During the puncture procedure, the microwave probe is first placed into the rotating disk. Rotating the second handle drives the threaded shaft and adjusting sleeve to rotate synchronously. Simultaneously, a lower pressure plate adheres to one side of the microwave probe, and a pressure sensor unit is installed on the inner side of the lower pressure plate to monitor the upward reaction force acting on the microwave probe in real time. The operator manually adjusts the fine-tuning lifting mechanism to smoothly lower the rotary insertion module and microwave probe, achieving precise puncture of the lesion area, ensuring puncture quality and efficiency, and laying the foundation for subsequent tumor ablation effects.

[0019] When the bottom of the microwave probe contacts hard tumor tissue, the squeezing force exerted by the tumor tissue on the probe is transmitted to the pressure sensing unit, and the pressure data is fed back to the control unit in real time. The control unit compares the collected pressure value with a preset threshold. Once the pressure value exceeds the threshold, it is determined that the probe has contacted the tumor tissue. At this time, the first forward and reverse motor starts and drives the drive gear to rotate. The drive gear meshes and drives the driven gear ring to rotate, thereby driving the microwave probe to reciprocate. The rotational motion during the puncture process can effectively reduce puncture resistance, ensure that the probe is stably inserted into the lesion area, and at the same time avoid damage to the needle body due to excessive force, thus ensuring the structural integrity of the microwave probe.

[0020] As the microwave probe gradually penetrates the patient's body, the rotating insertion module drives the probe downwards synchronously, and the adaptive adjustment module moves downwards in tandem. The rangefinder on this module monitors the distance between the module and the skin in real time. When the rangefinder detects that the module is about to contact the skin, the control command triggers the second forward and reverse motors to rotate, driving the threaded rod to rotate, which in turn drives the moving sleeve, support shaft and reinforcement mechanism to move synchronously, so that the reinforcement mechanism maintains a safe distance from the skin, avoids interference with the puncture path, and ensures the puncture accuracy of the microwave probe.

[0021] In addition, the reinforcement mechanism, fitted around the outside of the microwave probe needle, provides radial support to prevent bending deformation of the needle during puncture of hard tumors. As the needle is gradually inserted into the body, the reinforcement rings of the reinforcement mechanism can adaptively move closer together and contract, which neither hinders the puncture process nor hinders the gradual release of the needle, further improving puncture stability.

[0024] Example 1: Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The present invention provides a technical solution: A tumor interventional therapy device includes a fine-tuning lifting mechanism 4, a rotary insertion module 5, a microwave probe 6, and an adaptive adjustment module 7; A rotary insertion module 5 is installed on one side of the fine-tuning lifting mechanism 4. A microwave probe 6 is installed inside the rotary insertion module 5. The rotary insertion module 5 is used to drive the microwave probe 6 to rotate to ensure that the tumor is punctured. A vertically arranged adaptive adjustment module 7 is also fixedly connected to one side of the lower part of the rotary insertion module 5. One side of the adaptive adjustment module 7 is located on the outside of the microwave probe 6. The rotary insertion module 5 includes a placement plate 501 fixedly connected to the fine-tuning lifting mechanism 4. A rotating disk 502 is provided inside the placement plate 501. A limiting sleeve 503 is fixedly connected inside the rotating disk 502. A microwave probe 6 is provided on the inner side of the limiting sleeve 503. The first forward and reverse motor 511 is fixedly connected inside the placement plate 501. The main shaft end of the first forward and reverse motor 511 is fixedly connected to the drive gear 512. The outer side of the drive gear 512 is meshed with the driven gear ring 513. The inner side of the driven gear ring 513 is fixedly connected to the rotating disk 502. An adjusting sleeve 504 is fixedly connected to the top of the rotating disk 502. A threaded shaft 505 is screwed inside the adjusting sleeve 504. A second handle 506 is fixedly connected to the top of the threaded shaft 505. An adjusting plate 508 is rotatably connected to the outside of the threaded shaft 505. A lower pressure plate 507 is rotatably connected to the bottom of the adjusting plate 508. A pressure sensing unit 509 is installed at the bottom of the lower pressure plate 507. A control unit 510 is fixedly connected to the top of the adjustment plate 508.

[0025] Limiting rings 514 are provided on both the upper and lower sides of the driven gear ring 513. The inner side of the limiting ring 514 is fixedly connected to the rotating disk 502, and the outer side of the limiting ring 514 is rotatably connected to the placement plate 501.

[0026] A rotating block 515 is rotatably connected to one side of the bottom of the rotating disk 502. A rotating rod 516 is fixedly connected to one side of the rotating block 515. A connecting disk 517 is fixedly connected to the other side of the rotating rod 516. A laser light 518 is fixedly connected to the bottom of the connecting disk 517.

[0027] A connecting arm 2 is fixedly connected to one side of the connecting block 3, and a multi-angle adjustable base 1 is connected to the other end of the connecting arm 2.

[0028] In the clinical operation of microwave probe ablation, precise location of the puncture site is required first, followed by disinfection of the marked area. The operator holds the puncture instrument to pierce the skin, while simultaneously using imaging equipment to observe the puncture process in real time, ensuring that the puncture needle accurately penetrates the tumor tissue and providing assurance for subsequent treatment effects. However, the current mainstream clinical puncture method is still mainly manual operation by the operator. For hard tumors such as pancreatic cancer, some intrahepatic metastases of liver cancer, and scleroderma of the breast, these lesions are often solid, highly fibrotic, or accompanied by calcification, and their tissue density is significantly higher than that of normal soft tissue and ordinary tumor tissue. When manually holding the puncture needle to penetrate such lesions, a large pushing force is required to overcome the mechanical resistance of the tumor stroma. This operation process is prone to various problems: Firstly, the tip of the puncture needle is prone to bending, which can cause deviation of the puncture path and a significant reduction in puncture speed, affecting the subsequent tumor ablation effect. Secondly, excessive resistance may directly cause the puncture needle to break. Third, forced puncture can easily cause the tumor capsule to rupture, thereby increasing the risk of tumor cell spread; Fourth, if the puncture force decreases instantaneously, it may accidentally puncture normal tissue on the opposite side of the tumor, causing unnecessary damage. This solution uses a rotary insertion module 5 to fix the microwave probe 6. During the puncture operation, the microwave probe 6 is first placed in the rotating disk 502. By rotating the second handle 506, the threaded shaft 505 and the adjusting sleeve 504 rotate synchronously. Simultaneously, the lower pressure plate 507 is attached to one side of the microwave probe 6, and a pressure sensing unit 509 is configured inside the lower pressure plate 507 to monitor the upward reaction force on the microwave probe 6 in real time. The operator can manually adjust the fine-tuning lifting mechanism 4 to drive the rotary puncture module 5 and microwave probe 6 to descend smoothly, achieving precise puncture of the lesion area, ensuring puncture quality and efficiency, and laying the foundation for subsequent tumor ablation effects. When the bottom of the microwave probe 6 contacts the hard tumor tissue, the squeezing force of the tumor tissue on the probe is transmitted to the pressure sensing unit 509, and the pressure data is fed back to the control unit 510 in real time. The control unit 510 compares the collected pressure value with a preset threshold. Once the pressure value exceeds the threshold, it is determined that the probe has contacted the tumor tissue. At this time, the first forward and reverse motor 511 starts and drives the drive gear 512 to rotate. The drive gear 512 meshes and drives the driven gear ring 513 to rotate, thereby driving the microwave probe 6 to reciprocate. The rotational motion during the puncture process can effectively reduce puncture resistance, ensure that the probe is stably inserted into the lesion area, and at the same time avoid damage to the needle body due to excessive force, ensuring the structural integrity of the microwave probe 6. Also includes the following: During the puncture procedure, when the tip of the microwave probe 6 contacts the lesion tissue, the puncture resistance will increase sharply momentarily due to the dense structure of hard tumor lesions, which are often highly fibrotic and calcified. The lesion area exerts a reverse squeezing force on the needle tip, which is transmitted upward along the axial direction of the microwave probe 6. The pressure sensing unit 509 attached to the upper end of the probe collects the reaction force data in real time, and the pressure data is synchronously transmitted to the control unit 510 for threshold comparison. When the detected reaction force value exceeds the preset threshold range inside the control unit 510, the control system immediately triggers an action command, driving the first forward and reverse motor 511 to start running, which drives the drive gear 512 to rotate. The drive gear 512 and the driven gear ring 513 are meshed and transmitted, thereby driving the driven gear ring 513 and the rotating disk 502 fixed to it to rotate synchronously. A limiting sleeve 503 is provided on the inner side of the rotating disk 502. The microwave probe 6 is locked in the limiting sleeve 503, and the rotation of the needle body is realized by the rotation of the rotating disk 502.

[0029] It is worth noting that the upper end of the microwave probe 6 is fitted into a pre-set groove on the inner side of the lower pressure plate 507. The groove and the upper end of the probe are in clearance fit, which can both limit the axial movement of the probe and not interfere with the rotation of the probe, thus ensuring the smoothness and stability of the microwave probe 6 rotation puncture process. Before performing a puncture, the positioning and calibration of the equipment must be completed. The multi-angle adjustable base 1 provided in this solution can be stably installed on the support platform or ground base on the side of the hospital bed. The base has a built-in multi-degree-of-freedom adjustable joint, which can realize multi-dimensional posture adjustment such as horizontal rotation and pitch angle adjustment. By adjusting the joint angle of the multi-angle adjustable base 1, the operator can drive the connecting arm 2 and the connecting block 3 to flexibly adjust their spatial position, thereby driving the rotary insertion module 5 and microwave probe 6 connected to the connecting block 3 to move synchronously until the needle tip axis of the microwave probe 6 is precisely aligned with the puncture area marked before the operation, providing basic positioning guarantee for subsequent puncture operations.

[0030] To further improve the accuracy of puncture positioning, this solution adds a laser positioning auxiliary mechanism. The operator rotates the rotating rod 516, which drives the connecting plate 517 fixed to it for fine-tuning of the angle. A laser lamp 518 is fixed to the bottom of the connecting plate 517, positioned directly below the limiting sleeve 503, with its laser emission direction coaxial with the needle axis of the microwave probe 6. After activating the laser lamp 518, the laser beam is projected vertically onto the patient's surface. When the laser spot completely coincides with the pre-marked puncture point, precise positioning and calibration before puncture can be completed, effectively avoiding errors caused by manual visual positioning and improving the accuracy and reliability of the puncture operation.

[0031] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2Specifically, the fine-tuning lifting mechanism 4 includes a guide plate 401, an adjusting shaft 402 is rotatably connected inside the guide plate 401, a first handle 403 is fixedly connected to the top of the adjusting shaft 402, an adjusting block 404 is spirally connected to the outside of the adjusting shaft 402, one side of the adjusting block 404 is fixedly connected to the rotary insertion module 5, the outside of the adjusting block 404 is slidably connected to the guide plate 401, and a connecting block 3 is fixedly connected to one side of the guide plate 401.

[0032] When the microwave probe 6 is inserted into the skin, the first handle 403 is rotated to drive the adjustment shaft 402 to rotate, thereby driving the adjustment block 404 to make fine adjustments up and down, which in turn drives the rotary insertion module 5 to move up and down smoothly, ensuring the puncture work of the microwave probe 6. Also includes the following: The outer side of the adjusting block 404 is slidably connected to the guide plate 401 to ensure that the adjusting block 404 moves stably up and down, and to ensure that the microwave probe 6 moves stably up and down, avoiding shaking.

[0033] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 6 and Figure 7 Specifically, the adaptive adjustment module 7 includes a vertical plate 701 fixedly connected to the rotary insertion module 5. A second forward and reverse motor 702 is fixedly connected inside the vertical plate 701. A threaded rod 703 is fixedly connected to the end of the main shaft of the second forward and reverse motor 702. The other end of the threaded rod 703 is rotatably connected to the vertical plate 701. A movable sleeve 704 is screwed to the outer side of the threaded rod 703. A support shaft 705 is fixedly connected to one side of the movable sleeve 704. A reinforcing mechanism 706 is fixedly connected to the other end of the support shaft 705. A microwave probe 6 is provided on the inner side of the reinforcing mechanism 706. The outer side of the movable sleeve 704 is slidably connected to the vertical plate 701.

[0034] The reinforcement mechanism 706 includes a reinforcement ring 7061 fixedly connected to the support shaft 705. Multiple reinforcement rings 7061 are arranged and distributed vertically. A fixing rod 7065 is fixedly connected to one side of the uppermost reinforcement ring 7061, and the other end of the fixing rod 7065 is fixedly connected to the vertical plate 701.

[0035] All the upper surfaces of the reinforcing rings 7061 below the reinforcing rings 7061 connected to the fixing rod 7065 are fixedly connected to the connecting post 7063, and the other end of the connecting post 7063 is fixedly connected to the retaining ring 7064. The surface of the reinforcing ring 7061 above the support shaft 705 is provided with guide grooves 7066.

[0036] The connecting posts 7063 above the multiple reinforcing rings 7061 are all staggered; The number of guide grooves 7066 on the upper surface of the multiple reinforcing rings 7061 distributed vertically increases sequentially from bottom to top.

[0037] A rangefinder 7062 is installed at the bottom of the lowest reinforcing ring 7061.

[0038] As the microwave probe 6 gradually penetrates the patient's body, the rotary insertion module 5 drives the probe downward synchronously, and the adaptive adjustment module 7 moves downward in tandem. The rangefinder 7062 mounted on this module monitors the distance between the module and the skin in real time. When the rangefinder 7062 detects that the module is about to contact the skin, the control command triggers the second forward and reverse motor 702 to operate, driving the threaded rod 703 to rotate, which in turn drives the moving sleeve 704, the support shaft 705 and the reinforcement mechanism 706 to move synchronously, so that the reinforcement mechanism 706 maintains a safe distance from the skin, avoids interference with the puncture path, and ensures the puncture accuracy of the microwave probe 6. Furthermore, the reinforcement mechanism 706 is fitted onto the outer side of the microwave probe 6 needle body, providing radial support to prevent bending deformation of the needle body during puncture of hard tumors. As the needle body is gradually inserted into the body, the reinforcement rings 7061 of the reinforcement mechanism 706 can adaptively move closer together and contract, which neither hinders the puncture process of the needle body nor prevents the gradual release of the needle body, further improving puncture stability. Also includes the following: During the puncture process of the microwave probe 6, the rangefinder 7062 monitors the distance between the reinforcement mechanism 706 and the skin in real time. When the monitored distance exceeds the preset threshold, the second forward and reverse motor 702 is started and drives the threaded rod 703 to rotate, which drives the movable sleeve 704 sleeved on the outside of the threaded rod 703 to move synchronously, and then drives the reinforcement mechanism 706 to complete the contraction action through the support shaft 705. The specific contraction process is as follows: The connecting post 7063 above the bottom reinforcing ring 7061 moves upward. The outer side of the connecting post 7063 slides with the adjacent upper reinforcing ring 7061 to ensure that all reinforcing rings 7061 are always on the same vertical line. At the same time, the guide groove 7066 on the surface of the reinforcing ring 7061 is precisely matched with the connecting post 7063 below. By sliding the connecting post 7063 along the guide groove 7066, multiple reinforcing rings 7061 move closer to each other, completing the overall contraction of the reinforcing mechanism 706, and thus realizing the gradual release of the microwave probe 6-pin body.
