Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 10 This invention provides a technical solution: a puncture-guided visual probe for cryo-radiofrequency sampling, comprising a probe body 1, a main support 2 movably connected to the left side of the top of the probe body 1, a secondary support 3 movably connected to the right side of the top of the probe body 1, and an installation mechanism 4 movably connected between the top of the probe body 1 and the lower parts of the main support 2 and the secondary support 3. It should be noted that the installation mechanism 4 facilitates the quick installation of the guide tube 5 and the adjusting ring 8 onto the probe body 1, and allows a PVC film to be applied to the surface of the probe body 1 for isolation and protection.

[0042] A guide tube 5 is fixedly connected to the top of the main support 2. A support ring 6 is fixedly connected to the right side of the guide tube 5. An L-shaped spring telescopic rod 7 is fixedly connected to the bottom of the support ring 6. The right end of the L-shaped spring telescopic rod 7 is fixedly connected to the left side of the secondary support 3. An adjusting ring 8 is fixedly connected to the top of the secondary support 3. A wrapping mechanism 9 is movably connected inside the adjusting ring 8. It should be noted that the L-shaped spring telescopic rod 7 ensures the stability of the right end of the main support 2 when the main support 2, carrying the guide tube 5, moves horizontally to the right from the left side of the probe body 1.

[0043] A piercing needle 10 is movably inserted inside the guide tube 5. The middle part of the piercing needle 10 is movably inserted inside the adjusting ring 8. An adjusting mechanism 11 is movably connected between the right end of the piercing needle 10 and the surface of the support 3. The surface of the adjusting mechanism 11 is movably connected to the surface of the wrapping mechanism 9. The left end of the adjusting mechanism 11 is fixedly connected to the right side of the main support 2. A sealing mechanism 12 that cooperates with the piercing needle 10 is movably connected to the left side of the inner wall of the guide tube 5.

[0044] The sealing mechanism 12 includes a sealing groove 1201, which is formed at the left end of the inner wall of the guide tube 5. A support shaft 1202 is fixedly connected to the upper part of the inner wall of the sealing groove 1201. A baffle 1203 is rotatably connected to the middle part of the support shaft 1202. The side wall of the baffle 1203 overlaps with the inner wall of the sealing groove 1201. A compression spring 1204 is fixedly connected to the upper part of the inner wall of the sealing groove 1201. One end of the compression spring 1204 is fixedly connected to the right side of the baffle 1203. It should be noted that: by pressing the upper part of the baffle 1203 with the compression spring 1204, the baffle 1203 rotates around the support shaft 1202. At this time, the lower part of the baffle 1203 can stably fit against the inner wall of the sealing groove 1201, sealing the left end of the guide tube 5 and reducing the contamination caused by the use of the piercing needle 10; when the right end of the piercing needle 10 is pressed and moves to the left end of the guide tube 5, the piercing needle 10 can press the baffle 1203 to flip and release the sealing state.

[0045] In this embodiment, as Figures 1 to 10 As shown, the mounting mechanism 4 includes a movable groove 401, which is located on the left side of the top of the probe body 1. A compression spring 402 is fixedly connected to the right side of the inner wall of the movable groove 401.

[0046] A fixing groove 403 is provided on the right side of the top of the probe body 1. Both the fixing groove 403 and the movable groove 401 have mounting sleeves 404 inside. The left mounting sleeve 404 is slidably connected to the inside of the movable groove 401, and the right side of the left mounting sleeve 404 is fixedly connected to the left end of the compression spring 402. The right mounting sleeve 404 is fixedly connected to the inside of the fixing groove 403. It should be noted that when the guide tube 5, carrying the main support 2, is inserted into the left mounting sleeve 404, the guide tube 5 can slide in the position of the movable groove 401. When the adjusting ring 8, carrying the support 3, is inserted into the right mounting sleeve 404, the adjusting ring 8 is restricted to its current position.

[0047] Both the main bracket 2 and the secondary bracket 3 have symmetrically provided mounting grooves 405 inside. A connecting plate 406 is slidably connected inside the mounting groove 405. A pressing rod 407 is fixedly connected to the upper side wall of the connecting plate 406. A pin 408 is fixedly connected to the lower side wall of the connecting plate 406. A short spring 409 is fixedly connected between the side of the connecting plate 406 away from the pressing rod 407 and the inner wall of the mounting groove 405. It should be noted that: the mounting groove 405 is located at the lower part of the main bracket 2 and the slave bracket 3, and the mounting sleeve 404 is a concave sleeve to facilitate the insertion of the main bracket 2 and the slave bracket 3 into the corresponding mounting sleeve 404; the lower part of the main bracket 2 and the slave bracket 3 is tapered, and the inner bottom surface of the mounting sleeve 404 is tapered to facilitate the insertion of the main bracket 2 and the slave bracket 3 into the corresponding mounting sleeve 404, and to position the front and rear sides of the main bracket 2 and the slave bracket 3; trapezoidal guide blocks are fixedly connected to the left and right sides of the inner wall of the mounting sleeve 404 to facilitate the installation and positioning of the left and right sides of the main bracket 2 and the slave bracket 3.

[0048] The inner wall of the mounting sleeve 404 has symmetrically arranged slots 410, with two slots 410 corresponding to two pins 408. One end of the pin 408 passes through the mounting groove 405 and is movably inserted into the corresponding slot 410. It should be noted that by pressing the pressing rod 407, the pressing rod 407 moves the connecting plate 406 and the pin 408, thereby disengaging the pin 408 from the slot 410, allowing for quick disassembly of the guide tube 5 and adjusting ring 8 on the probe body 1.

[0049] In this embodiment, as Figures 1 to 10 As shown, a crossbar is fixedly connected between the two sides of the inner wall of the mounting groove 405, and the middle part of the connecting plate 406 is slidably connected to the surface of the crossbar. It should be noted that the crossbar is designed to ensure that the connecting plate 406 can move stably with the pin 408 during the pressing of the pressing rod 407.

[0050] The inner wall of the mounting slot 405 has symmetrically formed round holes. The pressing rod 407 and the pin 408 are respectively inserted into the two round holes. The end of the pin 408 near the slot 410 is beveled. It should be noted that by making the end of the pin 408 beveled, it is convenient for the main bracket 2 or the secondary bracket 3 to insert the corresponding pin 408 into the mounting sleeve 404.

[0051] In this embodiment, as Figures 1 to 10 As shown, the wrapping mechanism 9 includes a turntable 901, which is rotatably connected inside the adjusting ring 8. A conical toothed ring 902 that cooperates with the adjusting mechanism 11 is fixedly sleeved on the right side of the turntable 901.

[0052] A sealing belt wheel 903 is rotatably connected to the upper left side of the turntable 901. A sealing belt body 904 is wound around the middle of the sealing belt wheel 903. A movable sleeve 905 is fixedly connected to the middle left side of the turntable 901. A pressing telescopic rod 906 is movably inserted inside the movable sleeve 905. A pressing spring 907 is movably connected between the inner wall of the movable sleeve 905 and the surface of the pressing telescopic rod 906. One end of the pressing telescopic rod 906 passes through the movable sleeve 905 and is bonded to the end of the sealing belt body 904. It should be noted that when the end of the pressing telescopic rod 906 away from the axis of the turntable 901 is pressed, the pressing telescopic rod can slide inside the movable sleeve 905. At this time, the pressing telescopic rod 906 will not retract, and the pressing telescopic rod 906, along with the sealing belt body 904 on its surface, presses against the surface of the piercing needle 10.

[0053] An arc-shaped guide plate 908, which cooperates with the pressing telescopic rod 906, is fixedly connected to the lower left side of the adjusting ring 8. It should be noted that when the turntable 901 rotates with the pressing telescopic rod 906 to the position of the arc-shaped guide plate 908 on the surface of the adjusting ring 8, the pressing telescopic rod 906 is pressed and slides inside the movable sleeve 905. When the guide tube 5 slides to the right with the main bracket 2 inside the movable groove 401 to the axis position of the turntable 901, the end of the pressing telescopic rod 906 is pressed by the guide tube 5, and only then will the pressing telescopic rod 906 retract.

[0054] In this embodiment, as Figures 1 to 10 As shown, a support bearing is fixedly fitted onto the outer ring of the turntable 901, and the outer ring of the support bearing is fixedly connected to the inner ring of the adjusting ring 8. It should be noted that the support bearing ensures that the turntable 901 rotates stably within the adjusting ring 8.

[0055] A rotating shaft is fixedly connected to the upper left side of the turntable 901, and the sealing pulley 903 is rotatably connected to the middle of the rotating shaft.

[0056] In this embodiment, as Figures 1 to 10 As shown, the end of the pressable telescopic rod 906 furthest from the sealing tape body 904 is designed as an arc surface that mates with the arc-shaped guide plate 908. A connecting shaft is fixedly connected to the right side of the arc-shaped guide plate 908, and the arc-shaped guide plate 908 is fixedly connected to the left side of the adjusting ring 8 via the connecting shaft. It should be noted that the arc surface design reduces the frictional resistance during the contact process between the pressable telescopic rod 906 and the arc-shaped guide plate 908.

[0057] The end of the telescopic rod 906 near the guide tube 5 is spherical, and the end of the guide tube 5 near the telescopic rod 906 is conical. It should be noted that the combination of the spherical and conical shapes reduces the frictional resistance during the contact between the telescopic rod 906 and the piercing needle 10.

[0058] In this embodiment, as Figures 1 to 10As shown, the adjustment mechanism 11 includes a retaining ring 1101, which is fixedly sleeved on the right side of the piercing needle 10. Rectangular grooves 1102 are symmetrically opened from the upper part of the bracket 3. An adjustment frame 1103 is movably inserted between the two rectangular grooves 1102. A support telescopic rod 1104 is fixedly connected to the right end of the adjustment frame 1103. A U-shaped bracket 1105 is fixedly connected to the top of the support telescopic rod 1104. The upper part of the U-shaped bracket 1105 is movably engaged inside the retaining ring 1101.

[0059] A pad 1106 is fixedly connected to the right side of the bracket 3. A bevel gear rod 1107 that cooperates with the wrapping mechanism 9 is rotatably connected to the middle of the pad 1106. A one-way bearing 1108 is fixedly sleeved on the lower part of the bevel gear rod 1107. A spur gear 1109 is fixedly sleeved on the outer ring of the one-way bearing 1108. The inner wall of the adjusting frame 1103 has a toothed groove 1110 that cooperates with the spur gear 1109. It should be noted that the upper side wall of the bevel gear rod 1107 is meshed with the side wall of the conical toothed ring 902. When the adjusting frame 1103 moves to the left and rotates the spur gear 1109, the spur gear 1109 will not rotate with the bevel gear rod 1107 under the action of the one-way bearing 1108. When the adjusting frame 1103 moves to the right and rotates the spur gear 1109, the spur gear 1109 will rotate with the bevel gear rod 1107 under the action of the one-way bearing 1108.

[0060] The left end of the adjustment frame 1103 is slidably connected to a support rod 1111, and the left end of the support rod 1111 is fixedly connected to the right side of the main bracket 2.

[0061] In this embodiment, as Figures 1 to 10 As shown, a pressing block is fixedly connected to the right end of the adjusting frame 1103, and a support telescopic rod 1104 is fixedly connected to the top of the pressing block. It should be noted that the support telescopic rod 1104 is a spring telescopic rod; through the U-shaped bracket 1105, the right end of the piercing needle 10 can be supported, and by pressing against the pressing block, the U-shaped bracket 1105 can stably slide the piercing needle 10 inside the guide tube 5 to perform the piercing operation.

[0062] The method of use and advantages of this invention: The working process of this puncture visual probe based on cryo-radiofrequency sampling is as follows:

[0063] like Figures 1 to 10As shown, during use, firstly, a PVC plastic film is placed on the surface of the probe body 1. Then, the main bracket 2 at the bottom of the guide tube 5 is inserted into the mounting sleeve 404 on the left side of the probe body 1, and the secondary bracket 3 at the bottom of the adjusting ring 8 is inserted into the mounting sleeve 404 on the right side of the probe body 1. During this process, the inclined surfaces at the ends of the pins 408 at the bottom of the main bracket 2 and the secondary bracket 3 are pressed and slide into the mounting groove 405. When the pin 408 moves to the slot 410 position on the inner wall of the mounting sleeve 404, the compression spring 402 presses against the connecting plate 406, causing the pin 408 to extend and be inserted into the corresponding slot 410, thus completing the installation of the guide tube 5 and the adjusting ring 8, which facilitates the installation and disassembly of the guide tube 5.

[0064] Then, the piercing needle 10 is inserted into the guide tube 5 from the right side of the adjusting ring 8, so that the retaining ring 1101 at the right end of the piercing needle 10 engages with the U-shaped bracket 1105 at the right end of the adjusting frame 1103. Then, the right end of the adjusting frame 1103 is pressed, so that the adjusting frame 1103 slides to the left on the surfaces of the two rectangular grooves 1102 and the support rod 1111. The adjusting frame 1103 and the U-shaped bracket 1105 carry the piercing needle 10 to the left under the guidance of the guide tube 5 to perform the piercing operation.

[0065] After the piercing operation is completed, the piercing needle 10 is moved to the right by pulling the adjustment frame 1103. During this process, the toothed groove 1110 on the inner wall of the adjustment frame 1103 meshes with the surface of the spur gear 1109. The spur gear 1109 drives the bevel gear rod 1107 to mesh with the conical toothed ring 902, causing the conical toothed ring 902 to rotate the turntable 901. During the rotation of the turntable 901, the pressing telescopic rod 906 on the left side of the turntable 901 presses against the side wall of the arc-shaped guide plate 908 on the left side of the adjustment ring 8, so that the pressing telescopic rod 906 is pressed and the sealing tape body 904 presses against the surface of the piercing needle 10. During the rotation of the turntable 901 and the sealing tape wheel 903, the sealing tape body 904 at the end of the pressing telescopic rod 906 wraps around the surface of the piercing needle 10.

[0066] As the adjusting frame 1103 moves to the right with the piercing needle 10, the adjusting ring 8 rotates synchronously, so that the frequency of the sealing tape body 904 winding on the surface of the piercing needle 10 is synchronized with the speed of the adjusting frame 1103 to avoid the occurrence of missed winding. When the piercing needle 10 enters the interior of the guide tube 5, the compression spring 1204 inside the guide tube 5 presses against the baffle 1203 to flip and reset, and the baffle 1203 seals the left end of the guide tube 5. Meanwhile, the adjusting frame 1103, which continues to move, pulls the main support 2 to slide to the right inside the movable groove 401 through the support rod 1111. At this time, the guide tube 5 at the top of the main support 2 moves to the inner ring position of the adjusting ring 8, and the sealing tape body 904, which continues to rotate, winds the left end of the guide tube 5 together with the used piercing needle 10.

[0067] Press the rightmost main bracket 2 and the pressing rod 407 on the surface of the bracket 3. The pressing rod 407 moves the connecting plate 406 and the pin 408, causing the pin 408 to disengage from the corresponding slot 410, so that the guide tube 5 and the adjusting ring 8 can be pulled out from the probe body 1.
