Description

Technical Field

[0001] The invention relates to the technical field of animal radiofrequency ablation puncture assistance, in particular to an animal radiofrequency ablation puncture positioning assistance device. Background Art

[0002] Experimental research, also known as experimental research, is a method of collecting direct data. Select appropriate groups, control relevant factors through different means, and test the differences in responses between groups. The main purpose of researchers using the principles and methods of scientific experiments is to establish a causal relationship between variables. The general practice is that researchers put forward a tentative hypothesis of causal relationship in advance, and then test it through experimental operations. It is a controlled research method that evaluates the effect of one or more variables through the change of one or more variables. Animal radiofrequency ablation uses the heat generated by radiofrequency current to destroy diseased tissue. When radiofrequency current is introduced into the target tissue in the animal's body through electrodes, the ions in the tissue will vibrate with the change of current. This vibration friction will generate heat, causing the local tissue temperature to rise rapidly. The protein in the tissue will denature and the cell structure will be destroyed, leading to cell death, achieving the purpose of ablating the diseased tissue. At the same time, high temperature can also coagulate local blood vessels, reduce blood flow, and further prevent the development and spread of lesions.

[0003] In experimental research, animal diseases will be studied. In the process of experimental research on small animals, some small animals suffer from tumors, arrhythmia treatment, glandular hyperplasia and erosive tissue, which generally require surgical operations. These animals are in a physical state that does not meet the conditions for surgery due to congenital nutritional deficiencies and long-term illness. Radiofrequency ablation puncture can be performed in such scenarios. However, due to the certain differences in the size of different small animals, the existing radiofrequency ablation puncture device lacks the function of positioning assistance for different small animals, and cannot be adjusted for different small animal sizes. In addition, the puncture device is difficult to use with different types of operations during use, which causes many inconveniences. Based on this, an animal radiofrequency ablation puncture positioning assistance device is proposed through experimental research. Summary of the invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the device is in use, the operator places the small animal on the operating table, and sleeves the U-shaped plate seat on the outside of the small animal, and then stretches the length of the telescopic rod frame according to the body length of the small animal, and after the length is fixed, the adsorption fixing mechanism is rotated to cause the adsorption fixing mechanism to be adsorbed and fixed on the table, and then the Velcro fixing mechanism is used to restrain and limit the telescopic outer side of the small animal, and then the concave ring frame mechanism that slides and limits on the outer side of the telescopic rod frame is moved through the transmission action of the screw transmission mechanism, and the position of the electric-controlled telescopic rod and the puncture mechanism is adjusted. The puncture position is determined by adjusting the moving mechanism to move inside the concave ring frame mechanism according to the puncture position, and driving the electric-controlled telescopic rod and the puncture mechanism to rotate, thereby adjusting the circumferential position and length position of the electric-controlled telescopic rod and the puncture mechanism outside the small animal. Finally, the control device controls the electric-controlled telescopic rod to extend, and the puncture mechanism is inserted into the affected part of the small animal to assist in radiofrequency ablation and assist in positioning the puncture. The device is suitable for small animals of different sizes, and is easy to adjust and use. It is also small in size and suitable for animal experimental research and small animal surgery, and is easy to position and assist in puncture.

[0017] 2. When the puncture mechanism is puncturing, the vertical position of the puncture mechanism is driven by the extension of the electrically controlled telescopic rod, thereby adjusting the puncture position. When it is necessary to open the needle to remove and fix the eroded tissue tumor and other tissues, and when the needle core is opened and pierced in the middle of the tumor like an umbrella rib, the reversible electromagnet is started to generate magnetic force. At this time, the magnetic pole and the magnet column have a moving effect of repelling each other with the same poles. Under the limit of the hollow puncture rod, the magnet column pushes the piston 2 to move, and the piston 2 pushes the hydraulic oil inside the hydraulic oil chamber to move, thereby exerting a moving effect on the piston 3 and the support rod, prompting the limit support ring to move downward, and pushing the connecting rod to move downward, and then through the hinged position of the connecting rod, the semi-ring plate is prompted to open on the inner side of the semi-ring groove, so that the semi-ring plate is opened to the outside of the hollow puncture rod, and the position of the small animal tissue is limited, which is convenient for cooperating with different types of operations, increasing the use scenarios of the structure, and increasing the convenience of use, thereby stabilizing the use effect, facilitating control, and having a small displacement and a fast control response;

[0018] 3. When the puncture mechanism needs to move, the transmission motor rotates, driving the worm to rotate. The two ends of the worm are tapered and match the meshing turbine gear sleeve. As the rotation proceeds, the turbine gear sleeve is gradually pushed to move. Since the turbine gear sleeve is fixed, a moving operating force is applied to the annular slider, so that the annular slider and the bottom slide seat move on the inner side of the concave main ring frame. The annular slider and the bottom slide seat slide and limit on the inner side of the concave main ring frame, and are limited by the sleeve connection of the annular slide rod, which facilitates the stable moving position and reduces dislocation, thereby ensuring the stability of the structural movement, achieving more precise moving positions, facilitating more accurate moving operations, and facilitating stable movement.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 13 The present invention provides a technical solution: an animal radiofrequency ablation puncture positioning auxiliary device, comprising a U-shaped plate seat 1 and a concave ring frame mechanism 6, the number of the U-shaped plate seats 1 is two, and four telescopic rod frames 2 are fixedly installed on the opposite sides of the two U-shaped plate seats 1, and the outer sides of the four telescopic rod frames 2 are movably sleeved with Velcro fixing mechanisms 4, and the bottoms of the opposite sides of the two U-shaped plate seats 1 are fixedly installed with adsorption fixing mechanisms 3, and the opposite sides of the two U-shaped plate seats 1 are provided with label grooves 101, and the outer side of one of the two U-shaped plate seats 1 is fixedly installed with a control panel 102, and the outer side of the other of the two U-shaped plate seats 1 is fixedly installed with a hanger mechanism 5.

[0035] The top transmission of the concave ring frame mechanism 6 is provided with a screw transmission mechanism 7, and the concave ring frame mechanism 6 includes a concave main ring frame 601, the inner ring surface of the concave main ring frame 601 is fixedly installed with a turbine gear sleeve 603, the middle part inside the concave main ring frame 601 is fixedly installed with an annular slide bar 604, the four corners of the concave main ring frame 601 are fixedly installed with sliding sleeve seats 602, and a plurality of rolling support rollers 6021 are movably installed on the inner side of the sliding sleeve seat 602.

[0036] The working principle of the above technical solution is as follows: when in use, the operator places the small animal on the operating table, and sleeves the U-shaped plate seat 1 on the outside of the small animal, and then stretches the length of the telescopic rod frame 2 according to the body length of the small animal, and after fixing the length, rotates the adsorption fixing mechanism 3 to make the adsorption fixing mechanism 3 adsorbed and fixed on the table, and then uses the Velcro fixing mechanism 4 to restrain and limit the outside of the small animal, and then moves the concave ring frame mechanism 6 that slides and limits on the outside of the telescopic rod frame 2 through the transmission action of the screw transmission mechanism 7, and adjusts the electric-controlled telescopic rod 8 and the puncture mechanism 9 to the puncture position, and then adjusts the moving mechanism 10 to move the position inside the concave ring frame mechanism 6 according to the puncture position, and drives the electric-controlled telescopic rod 8 and the puncture mechanism 9 to move the position inside the concave ring frame mechanism 6 ... The retractable rod 8 and the puncture mechanism 9 rotate to adjust the circumferential position and length of the electrically-controlled telescopic rod 8 and the puncture mechanism 9 outside the small animal's body. Finally, the control device controls the electrically-controlled telescopic rod 8 to extend, and the puncture mechanism 9 is inserted into the affected part of the small animal. Finally, after confirming that the position of the top electrode of the puncture mechanism 9 is accurate, the external radiofrequency ablation device is started, and appropriate radiofrequency energy, time and other parameters are set according to the size and nature of the lesion, so that the lesion tissue gradually undergoes coagulative necrosis under the action of high temperature, assisting the radiofrequency ablation operation and assisting in positioning the puncture. The whole device is suitable for small animals of different sizes, and is easy to adjust and use. It is also small in size, suitable for animal experimental research and small animal surgery, and convenient for positioning puncture assistance.

[0037] In another embodiment, Figure 1-Figure 5As shown, the telescopic rod frame 2 includes four telescopic outer frames 201, and the inner sides of both ends of the four telescopic outer frames 201 are movably sleeved with telescopic inner plates 202, and the opposite sides of the four telescopic outer frames 201 are provided with groove openings 206, and the opposite sides of the telescopic inner plates 202 are fixedly installed with convex plates 205, and the opposite sides of the telescopic inner plates 202 are provided with a plurality of positioning grooves 204, and the outer sides of the four telescopic outer frames 201 are threadedly connected with adjustment bolts 203, and the convex plates 205 are slidably sleeved in the groove openings 206. On the inner side, the telescopic inner plate 202 and the convex plate 205 are convex, the telescopic outer frame 201 and the groove mouth 206 are concave, the positioning grooves 204 are linearly evenly distributed on the outer side of the telescopic inner plate 202, the specifications and dimensions of the adjusting bolts 203 are compatible with the specifications and dimensions of the positioning grooves 204, and the end of the telescopic inner plate 202 away from the telescopic outer frame 201 is fixedly installed on the opposite side of the U-shaped plate seat 1, and the four telescopic outer frames 201 and the telescopic inner plate 202 are rectangularly symmetrical and evenly distributed on the inner side of the U-shaped plate seat 1.

[0038] When the telescopic rod frame 2 is adjusted, the U-shaped plate seat 1 is stretched outward, and the relative length of the telescopic outer frame 201 and the telescopic inner plate 202 is changed. After reaching the required position, the concave ring frame mechanism 6 is located at the affected part of the small animal, and is inserted into the positioning groove 204 by adjusting the bolt 203 to fix it, thereby stabilizing the position of the telescopic rod frame 2. The telescopic outer frame 201 and the telescopic inner plate 202 maintain a smooth top surface through the convex plate 205 and the groove 206, which facilitates the stable sliding limit of the sliding sleeve seat 602 to avoid misalignment and maintain the structural movement. The stability of movement is ensured, and through the opening of the groove mouth 206, and the scale line is set on the inner side of the groove mouth 206, the position of the telescopic inner plate 202 on the inner side of the telescopic outer frame 201 can be easily observed, which is convenient for use in multiple working positions. The U-shaped plate seat 1 is fixed by the adsorption fixing mechanism 3. At this time, it is only necessary to release the limit of the adjusting bolt 203 and the positioning groove 204, and slide the telescopic inner plate 202 to the relative position on the inner side of the telescopic outer frame 201, so as to move the position of the concave ring frame mechanism 6, which is convenient for auxiliary adjustment and increases the convenience of telescopic adjustment.

[0039] In another embodiment, Figure 1-Figure 5 and Fig.12 As shown, the adsorption and fixing mechanism 3 includes four side supporting legs 301, and the four side supporting legs 301 are rectangular, symmetrical and evenly fixed on the bottom ends of the opposite sides of the two U-shaped plate seats 1, and two rubber pads 302 are fixedly installed on the bottom of the four side supporting legs 301, and the inner sides of the four side supporting legs 301 are fixedly sleeved with support tubes 304, and the top of the support tubes 304 is threadedly sleeved with a spiral top cover 303, and the top of the inner cavity of the spiral top cover 303 is fixedly installed with a sleeve column 306, and the bottom of the sleeve column 306 is fixedly installed with a piston 1 307, and the sleeve column 306 and the piston 1 307 are movably sleeved on the inner side of the support tube 304, and the bottom of the support tube 304 is fixedly installed with a suction cup 305.

[0040] When it is necessary to fix the bottom of the U-shaped plate seat 1, the spiral top cover 303 is rotated, and the threaded connection between the spiral top cover 303 and the support tube 304 causes the spiral top cover 303 to move upward during the rotation, and drives the sleeve 306 and the piston 307 to move upward. Since the suction cup 305 and the rubber pad 302 are in contact with the table surface, a negative pressure is formed on the inner side of the support tube 304 and the suction cup 305 during the upward movement of the piston 307, thereby adsorbing the suction cup 305 on the table surface, thereby prompting the adsorption and fixing mechanism 3 to fix the bottom of the U-shaped plate seat 1, reducing the misalignment of the operation and ensuring stability.

[0041] In another embodiment, Figure 1-Figure 5 As shown, the Velcro fixing mechanism 4 includes a double-sided Velcro 401 and a sliding frame 402, the outer side of the sliding frame 402 is threadedly connected with a fixing bolt 403, the sliding frame 402 is movably sleeved on the outer side of the telescopic inner plate 202, the specifications and dimensions of the fixing bolt 403 are compatible with the specifications and dimensions of the positioning groove 204, the inner side of the double-sided Velcro 401 is the Velcro fur surface, and the outer side of the double-sided Velcro 401 is the Velcro hook surface, the number of Velcro fixing mechanisms 4 is compatible with the number of telescopic rod frames 2, the hanger mechanism 5 includes a fixed seat 501 and a bottle hanging rod 502, the fixed seat 501 is fixed to the outer side of the U-shaped plate seat 1 by bolts, the bottle hanging rod 502 is movably penetrated and sleeved on the inside of the fixed seat 501, the internal thread of the fixed seat 501 is connected with a top screw, and the bottle hanging rod 502 is fixed to the inner side of the fixed seat 501 by the top screw.

[0042] When the Velcro fixing mechanism 4 is in use, the double-sided Velcro 401 is looped around the outside of the small animal's body, and the hook surface on the outside of the double-sided Velcro 401 is in contact with the fur surface on the inside, thereby achieving surrounding restraint and positioning of the small animal, and adjusting the position through multiple double-sided Velcro 401 and the sliding frame 402. After the sliding frame 402 slides, it is rotated and inserted into the positioning groove 204 through the fixing bolt 403, thereby fixing the sliding frame 402, and then adjusting and fixing the position of the double-sided Velcro 401, so as to facilitate multi-point or fixed-point restraint of small animals of different sizes, and facilitate subsequent positioning operations. After the hanging bottle rod 502 is fixed to the position of the fixing seat 501 by the top screw, the hanging bottle is hung on the hook at the top of the hanging bottle rod 502, so as to facilitate hanging water for the small animal, facilitate subsequent operations, and the drip effect of life maintenance.

[0043] In another embodiment, Figure 1-Figure 7As shown, the screw transmission mechanism 7 includes two Ω-shaped brackets 701 and a screw sleeve 704. The two Ω-shaped brackets 701 are fixedly mounted on opposite sides of the top telescopic outer frame 201. The internal threads of the screw sleeve 704 are connected with a transmission screw 703. One end of the transmission screw 703 is transmission-connected with a servo motor 702. The end of the servo motor 702 away from the transmission screw 703 is fixedly mounted on the opposite side of the Ω-shaped bracket 701. The end of the transmission screw 703 away from the servo motor 702 is rolling-limited on the opposite side of the Ω-shaped bracket 701 through a bearing seat. The screw sleeve 704 is fixedly mounted on the top of the concave main ring frame 601. The sliding sleeve 602 is movably sleeved on the outer side of the telescopic outer frame 201. The outer side of the rolling support roller 6021 is in rolling contact with the opposite side of the telescopic outer frame 201. The side of the sliding sleeve 602 away from the rolling support roller 6021 has a gap with the telescopic outer frame 201 that is adapted to the adjusting bolt 203.

[0044] When the position of the concave ring frame mechanism 6 needs to be moved, the servo motor 702 is started to rotate, and the rotation of the servo motor 702 drives the transmission screw 703 to rotate, and the transmission screw 703 and the screw sleeve 704 perform threaded transmission, thereby applying a threaded movement force to the screw sleeve 704, and the concave ring frame mechanism 6 is slidably sleeved on the outer side of the telescopic rod frame 2 by the sliding sleeve seat 602, and the rolling limit of the rolling support roller 6021 on the outer side of the telescopic outer frame 201 reduces the friction and plays a role in stabilizing the position to avoid dislocation, thereby supporting the concave ring frame mechanism 6 to move on the outer side of the telescopic rod frame 2, facilitating the movement of the screw sleeve 704 to push the concave ring frame mechanism 6 to move, and facilitating the control and movement of the structure by the control device of the radio frequency ablation device, thereby increasing the movement stability of the structure.

[0045] In another embodiment, Figure 1-Figure 11 As shown, the puncture mechanism 9 includes a top mounting seat 901 and a hollow puncture rod 902, a reversible electromagnet 903 is fixedly mounted on the top of the inner cavity of the hollow puncture rod 902, a magnet column 904 is movably sleeved on the inner side of the top of the hollow puncture rod 902, a piston 2 905 is fixedly mounted on the bottom of the magnet column 904, a piston 3 907 is movably sleeved on the inner side of the bottom end of the hollow puncture rod 902, and a hydraulic oil chamber 90 is provided on the opposite sides of the piston 2 905 and the piston 3 907. 6. A support rod 908 is fixedly installed at the bottom of the piston 3 907, and a limit support ring 909 is fixedly installed at the bottom of the support rod 908. Three connecting rods 912 are rotatably hinged at the bottom of the limit support ring 909. The ends of the three connecting rods 912 away from the limit support ring 909 are rotatably hinged with a semi-ring plate 911. Three semi-ring grooves 910 are opened at the bottom end of the hollow puncture rod 902, and a conical puncture electrode head 913 is fixedly installed at the bottom of the hollow puncture rod 902.

[0046] When the puncture mechanism 9 is puncturing, the vertical position of the puncture mechanism 9 is driven by the extension of the electrically controlled telescopic rod 8, thereby adjusting the puncture position. When it is necessary to open the needle to remove and fix the eroded tissue tumor and other tissues, and when the needle core is opened and inserted into the middle of the tumor like an umbrella rib, the reversible electromagnet 903 is started to generate magnetic force. At this time, the magnetic pole and the magnet column 904 have a moving effect of repelling each other with the same poles. Under the limit of the hollow puncture rod 902, the magnet column 904 pushes the piston 2 905 to move, and the piston 2 905 pushes the hydraulic oil inside the hydraulic oil chamber 906 to move, thereby exerting a moving effect on the piston 3 907 and the support rod 908, prompting the limit support ring 9 09 moves downward, and pushes the connecting rod 912 downward, and then through the hinged position of the connecting rod 912, the semi-annular plate 911 is prompted to open on the inner side of the semi-annular groove 910, so that the semi-annular plate 911 is opened to the outside of the hollow puncture rod 902, and the position of the small animal tissue is limited, which is convenient for coordinating with different types of surgical operations, increases the use scenarios of the structure, and increases the convenience of use, thereby stabilizing the use effect. If reset is performed, the reversible electromagnet 903 can be reversed at this time to achieve the effect of like-pole attraction on the magnet column 904, thereby driving the bottom structure to move upward, and then realizing the retraction and closure of the semi-annular plate 911, which is convenient for control, with small displacement and fast control response.

[0047] In another embodiment, Figure 1-Figure 11 As shown, the top mounting seat 901 is fixed to the bottom of the bottom mounting seat 801 by bolts, the hollow piercing rod 902 is fixedly installed at the bottom of the top mounting seat 901, the magnet column 904 is located at the bottom of the reversible electromagnet 903, the piston second 905 is movably sleeved on the inner side of the hollow piercing rod 902, the piston third 907 is located at the bottom of the piston second 905, the inner side of the hydraulic oil chamber 906 is filled with hydraulic oil, the limit support ring 909 is movably sleeved on the inner side of the hollow piercing rod 902, and the three semi-annular grooves 910 are evenly distributed on the inner side of the hollow piercing rod 902 in a circular shape. The specifications and dimensions of the semi-annular plate 911 are compatible with the specifications and dimensions of the semi-annular groove 910, and the semi-annular plate 911 is hinged on the inner side of the semi-annular groove 910, and there are two hinged positions of the semi-annular plate 911.

[0048] By fixing the bottom mounting seat 801 and the top mounting seat 901, it is convenient to replace the puncture mechanism 9, and it is convenient to replace the puncture mechanism 9 of different specifications and the opening position of the semi-ring plate 911 according to different operation needs. The hydraulic oil inside the hydraulic oil chamber 906 is convenient for the function of transmitting the driving force. The hydraulic oil is a non-polar or weakly polar liquid such as silicone oil and mineral oil, or a liquid with a low dielectric constant and low conductivity, and avoids the output position of the radio frequency microwave, so as to reduce the output at other positions. In terms of material, only the conical puncture electrode head 913 and the semi-ring plate 911 are selected as electrodes and metal materials that match the radio frequency microwave, which is convenient for cooperating with the radio frequency ablation operation, and the semi-ring plate 911 and the semi-ring groove 910 There are two types of hinge positions, which are hinged at the top and bottom of the semi-annular groove 910 respectively, and cooperate with the hinge position of the adjusting connecting rod 912 and the semi-annular plate 911. When hinged at the bottom of the semi-annular groove 910, if the connecting rod 912 pushes the top of the semi-annular plate 911 to expand outward, the tissue can be clamped and it is convenient to fix and pull. If the connecting rod 912 is hinged at the top of the semi-annular plate 911, the connecting rod 912 pushes the semi-annular plate 911 to move, and the bottom of the semi-annular plate 911 expands outward, which is convenient for increasing the contact surface during radiofrequency ablation, and after high-temperature necrosis of the tissue, the retraction will not limit the cavity, thereby reducing resistance, and different puncture mechanisms 9 can be replaced according to different types of operations to facilitate cooperation with different operations.

[0049] In another embodiment, Figure 3 and Figure 4 and Fig.10 and Fig.13As shown, the moving mechanism 10 includes an annular slider 1001, a bottom slide seat 1008 is fixedly installed at the bottom of the annular slider 1001, a mounting groove 1005 is provided on the inner side of the annular slider 1001, a transmission motor 1006 is fixedly installed on the inner side of the mounting groove 1005, an output end of the transmission motor 1006 is transmission-connected with a worm 1004, an outer side of the worm 1004 away from the transmission motor 1006 is movably sleeved with a support shaft seat 1007, a plurality of ball grooves 1003 are provided on both sides of the annular slider 1001, a rolling ball 1002 is rollingly installed on the inner side of the ball groove 1003, an electric control telescopic rod 8 is fixedly installed on the bottom of the bottom slide seat 1008, the annular slider 1001 is slidably installed on the inner side of the concave main ring frame 601, and the annular slider 1001 and The specifications and dimensions of the bottom slide seat 1008 are compatible with the specifications and dimensions of the concave main ring frame 601.

The shape of the worm 1004 from both ends to the middle is arc-shaped, and the specifications and dimensions of the worm 1004 are compatible with the specifications and dimensions of the turbine gear sleeve 603. The support shaft seat 1007 is fixedly installed on the inner side of the mounting groove 1005, and the outer side of the rolling ball 1002 is in rolling contact with the inner side of the concave main ring frame 601. The ball groove 1003 and the rolling ball 1002 are evenly distributed in an arc-shaped circle on both sides of the annular slider 1001.

[0050] When the puncture mechanism 9 needs to move, the transmission motor 1006 rotates, driving the worm 1004 to rotate. The two ends of the worm 1004 are tapered and match the meshing turbine gear sleeve 603. As the rotation proceeds, the turbine gear sleeve 603 is gradually pushed to move. Since the turbine gear sleeve 603 is fixed, a moving operating force is applied to the annular slider 1001, so that the annular slider 1001 and the bottom slide 1008 move inside the concave main ring frame 601. 08 is limited by sliding on the inner side of the concave main ring frame 601, and is limited by the sleeve connection of the annular slide bar 604, so as to stabilize the moving position and reduce misalignment, thereby ensuring the stability of the structural movement. Through the transmission of the worm 1004 and the turbine gear sleeve 603, the self-locking feature is realized, and the transmission ratio is increased. The worm 1004 rotates many times and changes the moving position of the turbine gear sleeve 603 less, thereby realizing a more precise moving position, facilitating more accurate moving operations, and facilitating stable movement.
