Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a prostate thermal steam ablation handle and steam ablation system based on rotation adjustment. Background Technology

[0002] The prostate gland is the largest unpaired solid organ among accessory glands, located in the pelvic cavity. For benign prostatic hyperplasia (BPH), minimally invasive treatment techniques such as microwave therapy, puncture ablation, and steam therapy are currently the main approaches. These techniques require only local anesthesia, are easy to perform, cause minimal trauma, have little intraoperative bleeding, and allow for rapid postoperative recovery, thus gradually gaining popularity.

[0003] However, current methods primarily combine a prostate steam ablation catheter with a rigid endoscope, using steam ablation for prostate surgery. When the surgeon rotates the prostate steam ablation catheter to locate the ablation area laterally, they also need to rotate the camera at the rear of the rigid endoscope to ensure the image displayed on the screen matches the catheter's position. Rigid endoscopes are typically expensive, and the ablation catheter needs to be inserted into the rigid endoscope system during surgery. This results in a heavy load for the surgeon, longer preparation time, and greater inconvenience, making it difficult to monitor the treatment area in real time. Utility Model Content

[0063] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0064] The following is combined with Figures 1-12The present invention provides a detailed description of the prostate hot steam ablation handle and steam ablation system based on rotation adjustment provided by the present invention through specific embodiments and application scenarios.

[0065] In the first aspect, such as Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a prostate thermal steam ablation handle based on rotation adjustment, including: handle body 1, catheter assembly 2 and rotation adjustment component 4;

[0066] The catheter assembly 2 includes a guide rod 21, a puncture needle 22, and a camera module 23. The guide rod 21 is connected to the handle body 1. The puncture needle 22 is movably inserted through the guide rod 21. The camera module 23 is disposed on the guide rod 21. The camera module 23 is used to acquire treatment images of the area to be ablated and is configured to be electrically connected to the host 13 for displaying the treatment images.

[0067] The rotation adjustment element 4 is disposed on the handle body 1 and is configured to be electrically connected to the main unit 13;

[0068] The rotation adjustment component 4 is used to receive rotation input to control the rotation of the treatment image displayed on the host 13.

[0069] It is understandable that the handle body 1 has an outer shell, which is assembled from multiple different shells. The outer shell includes a main shell and a handheld part that is bent and connected to the main shell.

[0070] The needle tip of the puncture needle 22 can extend or retract from the first end of the guide rod 21. The camera module 23 is disposed at the first end of the guide rod 21 and is disposed opposite to the needle exit area of ​​the puncture needle 22. The second end of the guide rod 21 is connected to the front end of the main housing. The rotating adjustment component 4 can be disposed at the rear end of the main housing. The handheld part is used to be held so as to adjust the posture of the entire handle body 1.

[0071] The camera module 23 can be configured with a lens bracket, a camera, and multiple light sources arranged around the camera. The camera and light sources are respectively mounted on the lens bracket, which is connected to the guide rod 21. The light sources are used to provide illumination for the camera's shooting environment, and can be LED lights.

[0072] For the host 13, the host 13 is configured to control the rotation of the treatment image based on the rotation input received from the rotation adjustment member 4. Exemplarily, the host 13 can generate a rotation matrix from the rotation angle information of the rotation adjustment member 4, and control the pixels displayed on the host 13 screen according to the rotation matrix to achieve the purpose of controlling the image rotation. This part of the image rotation control can be implemented using image rotation algorithms known in the art, which will not be described in detail here.

[0073] The prostate thermal steam ablation handle of this utility model comprises a handle body 1, a catheter assembly 2, and a rotation adjustment component 4. The catheter assembly 2 includes a guide rod 21, a puncture needle 22, and a camera module 23. The camera module 23 is integrated into the guide rod 21 to achieve maximum proximity to the exit area of ​​the puncture needle 22. It can maintain consistency with the movement of the puncture needle 22 at all times. The doctor can adjust the exit position and posture of the puncture needle 22 through the handle body 1. While the camera module 23 acquires treatment images of the area to be ablated, the rotation adjustment component 4 can be manually rotated to perform rotation input, thereby actively adjusting the display posture of the treatment image on the host 13. This ensures that the treatment image displayed on the host 13 is consistent with the doctor's holding posture of the prostate thermal steam ablation handle, allowing the doctor to more accurately control the puncture needle 22 to perform steam ablation treatment on the lesion. It is also beneficial to observe the real-time situation during the steam ablation treatment, improving the guidance effect of the position and movement of the puncture needle 22 during the steam ablation process.

[0074] Compared to existing prostate surgery designs that combine a prostate steam ablation catheter with a rigid endoscope, the prostate steam ablation handle shown in this invention is low-cost, lightweight, and easy to operate. It allows for real-time acquisition of treatment images of the area to be ablated during the operation of the handle, and the display posture of the treatment image on the host 13 can be manually adjusted to conform to the doctor's usage habits, avoiding medical accidents caused by misjudgment.

[0075] It should be noted that the treatment images are different at different time points during the treatment of the ablation area. For example, before the treatment of the ablation area, the treatment image represents the image of the doctor rotating the handle body to find the ablation area in the lateral position; during the treatment of the ablation area, the treatment image represents the image of the needle 22 being withdrawn and the corresponding withdrawal area; after the treatment of the ablation area is completed, the treatment image represents the image of the needle 22 being withdrawn.

[0076] In some embodiments, such as Figure 2 As shown, the rotating adjustment component 4 includes: a rotary potentiometer 41 and a knob 42;

[0077] A rotary potentiometer 41 is disposed on the handle body 1 and is configured to be electrically connected to the main unit 13; a knob 42 is used to receive rotation input, and the knob 42 is connected to the rotary potentiometer 41.

[0078] It is understandable that the knob 42 and the rotating potentiometer 41 are connected by a shaft. The rotating potentiometer 41 usually contacts the resistive element inside it through a brush. When the shaft rotates, the shaft can drive the brush to slide along the resistive element to change the position of the voltage divider point on the resistive element.

[0079] The knob 42 is exposed on the surface of the handle body 1. The knob 42 is used to receive the rotation input of the operator (e.g., a doctor) and drive the rotation shaft of the rotary potentiometer 41 to rotate. The angle information input by the operator can be converted into voltage information transmitted to the host 13 via the rotary potentiometer 41. The host 13 will determine the rotation angle of the treatment image according to the received voltage information, so as to automatically rotate and correct the displayed treatment image to conform to the doctor's usage habits. This makes it easier for the doctor to control the needle insertion of the puncture needle 22 while observing the treatment image of the puncture needle 22 in real time.

[0080] like Figure 3 As shown, when the operator (e.g., a doctor) operates the handle body 1, the rotation of the treatment image P can be controlled by rotating the adjustment component 4 to ensure that the treatment image P always follows the direction of rotation. Figure 3 The posture is displayed as shown. For example, before the puncture needle 22 is withdrawn, the needle tip of the puncture needle 22 is vertically downward as shown in the treatment image P. However, during the treatment of the area to be ablated, the needle tip of the puncture needle 22 is tilted as shown in the treatment image P. This image display posture is consistent with the doctor's holding posture of the prostate thermal steam ablation handle, and it also makes it convenient for the doctor to observe the treatment images of steam ablation treatment using the puncture needle 22 in real time.

[0081] In some embodiments, such as Figure 2 and Figure 3 As shown, the handle body 1 has a receiving cavity 101 and is equipped with a video cable connector 6 and an RF cable connector 7 for connecting the host 13.

[0082] The prostate hot steam ablation handle also includes a circuit board 5, which is disposed in the receiving cavity 101. The camera module 23 and the rotation adjustment component 4 are electrically connected to the circuit board 5, and the circuit board 5 is electrically connected to the video cable connector 6 and the radio frequency cable connector 7, respectively.

[0083] Understandably, by configuring the video cable connector 6 and the radio frequency cable connector 7, the video signal and the radio frequency signal can be transmitted separately, ensuring that the two signals do not interfere with each other. This ensures both the clarity of the video acquisition and facilitates precise adjustment of the display orientation of the treatment image.

[0084] Circuit board 5 can be a PCB board. Circuit board 5 is used to process the video signal acquired by camera module 23 and transmit the processed video signal to video cable connector 6. When the operator rotates knob 42, circuit board 5 is also used to process the electrical signal generated by the rotary potentiometer 41 corresponding to the rotation adjustment component 4 and transmit the processed electrical signal to radio frequency cable connector 7.

[0085] For example, such as Figure 2 and Figure 3As shown, the prostate hot steam ablation handle is equipped with a video cable X1 and an RF cable X2. One end of the video cable X1 is plugged into the video cable connector 6, and the other end is plugged into the video interface on the host 13. One end of the RF cable X2 is plugged into the RF cable connector 7, and the other end is plugged into the RF interface on the host 13.

[0086] In some embodiments, such as Figure 5 and Figure 6 As shown, the guide rod 21 includes a guide joint 211;

[0087] The camera module 23 is located on the guide connector 211, which has a needle insertion and withdrawal channel 2111. The puncture needle 22 passes through the needle insertion and withdrawal channel 2111 and exits under the guidance of the needle insertion and withdrawal channel 2111. The exit direction of the puncture needle 22 is set at an angle to the shooting direction of the camera module 23.

[0088] It is understandable that the angle α between the shooting direction of the camera module 23 and the exit direction of the puncture needle 22 can be set to 55°~75°. For example, the angle α can be 55°, 60°, 65°, 70°, 75° and other suitable angle values. Preferably, the angle α is 70°. This design can effectively ensure that the shooting range of the camera module 23 can accurately face the exit area of ​​the puncture needle 22 and completely cover the exit area of ​​the puncture needle 22, so as to accurately and comprehensively obtain the treatment image of steam ablation treatment using the puncture needle 22.

[0089] In practical applications, the shooting angle of the camera module 23 can be 140°, that is, a shooting angle of 70° above and below the shooting center line of the camera module 23. In other embodiments, the camera module 23 may also use image acquisition devices with other shooting ranges.

[0090] In some implementations, such as Figure 7 and Figure 8 As shown, the guide joint 211 is also provided with a flushing channel 2112, a return water channel 2113 and a wiring channel 2114;

[0091] The guide rod 21 also includes a rod body 212, the first end of which is connected to the guide joint 211, and the second end of which extends into the handle body 1; the rod body 212 contains an infeed / outfeed needle tube 2121, a flushing tube 2122, a return water tube 2123, and a cable routing tube 2124; the infeed / outfeed needle channel 2111 is connected to the infeed / outfeed needle tube 2121, the flushing channel 2112 is connected to the flushing tube 2122, the return water channel 2113 is connected to the return water tube 2123, and the cable routing channel 2114 is connected to the cable routing tube 2124;

[0092] The puncture needle 22 is sequentially inserted into the needle insertion / retraction channel 2111 and the needle insertion / retraction tube 2121. The signal line of the camera module 23 is sequentially inserted into the wiring channel 2114 and the wiring tube 2124. The signal line of the camera module 23 is used to transmit the image signal acquired by the camera module 23 and to power the camera module 23.

[0093] It is understandable that the guide rod 21 is formed by axially splicing the guide joint 211 and the rod body 212. For example, the guide joint 211 and the rod body 212 can be connected by adhesive bonding. Sealing rings can be set between the flushing channel 2112 and the flushing pipe 2122, and between the return water channel 2113 and the return water pipe 2123 to achieve waterproof sealing.

[0094] In this embodiment, the needle insertion / retraction channel 2111 and needle insertion / retraction tube 2121 form a first extension channel for the puncture needle 22 to pass through. The flushing channel 2112 and flushing tube 2122 form a second extension channel for delivering cleaning fluid (e.g., saline) to the steam ablation position. The return water channel 2113 and return water tube 2123 form a third extension channel for discharging wastewater from the steam ablation position. The wiring channel 2114 and wiring tube 2124 form a fourth extension channel for laying the signal line of the camera module 23. This design ensures that each extension channel is independent of the others and does not affect each other. Furthermore, the guide connector 211 and the rod body 212 both adopt independent channel designs, which can effectively separate the water path from the wiring, reduce the sealing difficulty, reduce costs, and improve the production and assembly efficiency of the guide rod 21.

[0095] It should be noted that the infeed and retraction needle tube 2121 can be configured to be connected to the heating module 12 and the water supply tube in sequence. The heating module 12 is located in the receiving cavity 101. The water supply tube, the flushing tube 2122 and the return water tube 2123 extend from the receiving cavity 101 of the handle body 1 to the outside of the handle body 1, respectively. The heating module 12 is used to heat the sterile water supplied by the water supply tube into steam, and the puncture needle 22 is used to transmit the steam to the steam ablation position.

[0096] In some implementations, such as Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the guide joint 211 is also provided with a flushing channel 2112, a return water channel 2113 and a wiring channel 2114;

[0097] The guide rod 21 also includes a rod body 212, the first end of which is connected to the guide joint 211, and the second end of which extends into the handle body 1; the rod body 212 has an inlet / outlet needle tube 2121, a water pipe 2125, and a cable pipe 2124 formed therein; the inlet / outlet needle channel 2111 is connected to the inlet / outlet needle tube 2121, the flushing channel 2112 and the return water channel 2113 are respectively connected to the first end of the water pipe 2125, the second end of the water pipe 2125 is configured to be connected to the flushing pipe and the drain pipe through a three-way valve 201, and the cable channel 2114 is connected to the cable pipe 2124;

[0098] The puncture needle 22 is sequentially inserted into the needle insertion / retraction channel 2111 and the needle insertion / retraction tube 2121, and the signal line of the camera module 23 is sequentially inserted into the wiring channel 2114 and the wiring tube 2124.

[0099] It is understandable that, for the guide connector 211, the first port of the flushing channel 2112 and the first port of the return water channel 2113 extend to both sides of the outlet end of the needle inlet and outlet channel 2111, respectively. The second port of the flushing channel 2112 and the second port of the return water channel 2113 are connected and connected to the end of the water pipe 2125 near the guide connector 211.

[0100] In practical applications, considering that water injection and sewage discharge do not occur simultaneously, this embodiment can use a single water pipe 2125 to replace the flushing pipe 2122 and return pipe 2123 of the above embodiment. The water pipe 2125 is connected to both the flushing pipe and the sewage discharge pipe via a three-way valve 201. When delivering cleaning fluid (e.g., saline solution) to the steam ablation location, the three-way valve 201 can be switched to the first state to connect the flushing pipe and the water pipe 2125. When discharging sewage from the steam ablation location, the three-way valve 201 can be switched to the second state to connect the water pipe 2125 and the sewage discharge pipe. Thus, this embodiment achieves both water injection and sewage discharge operations using the same water pipe 2125. While meeting practical application requirements, the design size of the water pipe 2125 can be maximized, thereby improving the effectiveness of water injection and sewage discharge.

[0101] Similarly, the guide rod 21 shown in this embodiment can also be formed by axially splicing the guide joint 211 and the rod body 212. The needle insertion / retraction channel 2111 and the needle insertion / retraction tube 2121 form a first extension channel as shown in the above embodiment for the puncture needle 22 to pass through. The flushing channel 2112 and the return water channel 2113 are respectively connected to the water pipe 2125 to form an extension channel for flushing and drainage in different time periods. The wiring channel 2114 and the wiring tube 2124 form a fourth extension channel as shown in the above embodiment for laying the signal line of the camera module 23. This design can also ensure that each extension channel is independent of each other and does not affect each other. Furthermore, the guide joint 211 and the rod body 212 both adopt independent channel designs, which can effectively separate the water path and the wiring, reduce the sealing difficulty, reduce costs, and improve the production efficiency and assembly efficiency of the guide rod 21.

[0102] It should be noted that the infeed and retraction needle tube 2121 can be configured to be connected to the heating module 12 and the water supply pipe in sequence. The heating module 12 is located in the receiving cavity 101. The water supply pipe, flushing pipe and drain pipe extend from the receiving cavity 101 of the handle body 1 to the outside of the handle body 1. The heating module 12 is used to heat the sterile water supplied by the water supply pipe into steam, and the puncture needle 22 is used to transmit the steam to the steam ablation position.

[0103] In some embodiments, such as Figure 2 As shown, the prostate thermal steam ablation handle also includes a needle control component 3; the needle control component 3 is disposed in the receiving cavity 101 and connected to the puncture needle 22, the needle control component 3 is electrically connected to the circuit board 5, and can switch between a first state and a second state.

[0104] When the needle control component 3 is in the first state, it controls the puncture needle 22 to move relative to the guide rod 21 toward the guide connector 211, thereby driving the puncture needle 22 out. When the needle control component 3 is in the second state, it controls the puncture needle 22 to move relative to the guide rod 21 toward the side away from the guide connector 211, thereby driving the puncture needle 22 back out. The needle control component 3 can be a telescopic rod or a linear motor, etc.

[0105] In some embodiments, such as Figure 4 As shown, the needle control component 3 includes: a sleeve 31, a stator assembly 32, and a mover assembly 33;

[0106] The stator assembly 32 includes a first stator 321 and a second stator 322, which are disposed in the sleeve 31 along the axial direction of the sleeve 31; the mover assembly 33 includes a sliding seat 331 and a mover 332, which is disposed in the sliding seat 331. The sliding seat 331 is movably disposed in the sleeve 31 along the axial direction of the sleeve 31. A through hole extending along the axial direction of the sleeve 31 is formed in the sliding seat 331. The puncture needle 22 passes through the through hole and is connected to the sliding seat 331.

[0107] The first stator 321 and the second stator 322 cooperate to drive the mover 332 to move the sliding seat 331 within the sleeve 31.

[0108] It is understood that the first stator 321 and the second stator 322 can be coils, the mover 332 can be a permanent magnet, and the through hole of the sliding seat 331 can be used to install the puncture needle 22, as well as the flushing pipe 2122, the return water pipe 2123 and the wiring pipe 2124 shown in the above embodiment.

[0109] The sliding seat 331 is adapted to switch between a first position and a second position. When the first stator 321 is energized and the second stator 322 is de-energized, the needle control component 3 is in the first state. Under the magnetic force of the first stator 321, the mover 332 drives the sliding seat 331 to move forward in the sleeve 31 until the sliding seat 331 reaches the first position. At this time, the sliding seat 331 drives the puncture needle 22 to complete the needle withdrawal.

[0110] Accordingly, when the first stator 321 is de-energized and the second stator 322 is energized, the needle control component 3 is in the second state. Under the magnetic force of the second stator 322, the mover 332 drives the sliding seat 331 to retract within the sleeve 31 until the sliding seat 331 reaches the second position. At this time, the sliding seat 331 drives the puncture needle 22 to complete the needle retraction.

[0111] In some embodiments, such as Figure 1 and Figure 2 As shown, the prostate thermal steam ablation handle also includes:

[0112] The combination button 8 includes a flushing button 81 and a needle insertion button 82. The flushing button 81 and the needle insertion button 82 are respectively located on the handle body 1 and are configured to be electrically connected to the host 13. The flushing button 81 is used to control the water supply source to supply flushing water to the flushing tube 2122 when it is pressed. The flushing button 81 and the needle insertion button 82 are used to control the needle control component 3 to drive the puncture needle 22 out when they are pressed at the same time.

[0113] The needle retraction button 11 is located on the handle body 1 and is configured to be electrically connected to the host 13. The needle retraction button 11 is used to control the needle control component 3 to drive the puncture needle 22 to retract when it is pressed.

[0114] The steam button 9 is located on the handle body 1 and is configured to be electrically connected to the host 13. The steam button 9 is used to control the heating module 12 to work when it is pressed, so as to deliver steam into the puncture needle 22.

[0115] It is understood that a button plate 10 corresponding to the flushing button 81, the needle insertion button 82, the needle withdrawal button 11, and the steam button 9 is provided in the receiving cavity 101 of the handle body 1. The button plate 10 is provided with trigger elements corresponding to each button, such as limit switches or pressure-sensitive elements. The button plate 10 is communicatively connected to the circuit board 5 shown in the above embodiment.

[0116] For the combination button 8, the flushing button 81 is movably inserted into the needle insertion button 82, and the flushing button 81 protrudes from the needle insertion button 82. When the flushing button 81 is pressed, a first pressing signal generated by the flushing button 81 is transmitted to the host 13. The host 13 controls the water supply to supply flushing water to the flushing tube 2122 to flush the steam dissipation area. When the flushing button 81 is pressed again, the needle insertion button 82 is pressed, so that the flushing button 81 and the needle insertion button 82 are pressed simultaneously. A second pressing signal generated by the needle insertion button 82 is transmitted to the host 13. The host 13 controls the needle control component 3 located in the handle body 1 to be in the first state, so as to drive the puncture needle 22 to be inserted.

[0117] As for the needle withdrawal button 11, the needle withdrawal button 11 can be set at a position corresponding to the needle control component 3. When the needle withdrawal button 11 is pressed, the third pressing signal generated by the needle withdrawal button 11 is transmitted to the host 13. The host 13 controls the needle control component 3 set in the handle body 1 to be in the second state so as to drive the puncture needle 22 to withdraw.

[0118] For the steam button 9, when the steam button 9 is pressed, the fourth pressing signal generated by the steam button 9 is transmitted to the host 13. The host 13 controls the heating module 12 connected to the puncture needle 22 to work. The heating module 12 heats the sterile water and converts the sterile water into steam. Under the action of the air pressure difference, the steam will be automatically delivered into the puncture needle 22.

[0119] For example, the heating module 12 is disposed in the receiving cavity 101 of the handle body 1. The heating module 12 may be a bellows with a coil configured. The bellows is connected to the end of the puncture needle 22. A steam channel is formed inside the puncture needle 22, and the needle tip of the puncture needle 22 is provided with a steam outlet.

[0120] In practical applications, the host 13 can supply high-frequency current to the coil corresponding to the heating module 12 through the current generating device. When the high-frequency current flows through the coil, it will form eddy current to heat the bellows. At this time, the sterile water in the bellows is quickly converted into steam in a short time.

[0121] In the second aspect, such as Figure 3 As shown, this utility model embodiment also provides a steam ablation system, including:

[0122] The prostate thermal steam ablation handpiece based on rotation adjustment as described above;

[0123] The main unit 13 includes a body 131 and a display module 132. The camera module 23, the rotation adjustment component 4 and the display module 132 are electrically connected to the body 131 respectively. The display module 132 is used to display treatment images.

[0124] Understandably, the host 13 can be a laptop computer, which is used to provide power, signal transmission and control, sterile water supply and human-computer interaction interface for the prostate hot steam ablation handpiece.

[0125] For example, the device 131 may be configured with a motherboard, which is communicatively connected to the display module 132. Based on an image rotation algorithm program known in the art set on the motherboard, the device 131 controls the rotation of the treatment image displayed on the display module 132 according to information fed back from the rotation adjustment component 4. The display module 132 may be a liquid crystal display screen. The motherboard is communicatively connected to the video cable connector 6 on the prostate thermal steam ablation handle via a video interface and video cable X1, and to the radio frequency cable connector 7 on the prostate thermal steam ablation handle via a radio frequency interface and radio frequency cable X2.

[0126] In actual operation, the doctor adjusts the needle exit position and posture of the puncture needle 22 through the handle body 1, and observes the treatment image captured by the camera module 23 in real time through the display module 132. During this process, the doctor can manually rotate the adjustment component 4. The adjustment component 4 converts the angle information input by the doctor into voltage information transmitted to the host 13. The host 13 will determine the rotation angle of the treatment image according to the received voltage information, realize automatic rotation correction of the displayed treatment image, and ensure that the treatment image is displayed in the display module 132 in the set posture, so as to conform to the doctor's usage habits and facilitate the doctor to control the needle exit of the puncture needle 22 while observing the treatment image of the puncture needle 22 in real time.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
