Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a thrombus removal device. Background Art

[0002] Thrombi are small pieces of blood formed on the surface of peeling or repaired parts of the inner surface of the cardiovascular system blood vessels. In the variable fluid-dependent type, thrombi are composed of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells. Long-term accumulation of thrombi inside the patient's blood vessels will cause poor blood flow, which will cause certain harm to the patient's body. Therefore, a thrombus removal device is needed to remove the thrombus.

[0003] When using the thrombus removal device in the prior art, due to the different operating proficiency among different medical staff, when the medical staff are performing thrombus removal, they are disturbed by their own factors or external factors, and are prone to improper control of the puncture angle or depth, resulting in the puncture needle failing to smoothly enter the blood vessel cavity, but penetrating the posterior wall of the blood vessel, etc., thereby increasing the patient's physical pain and psychological burden.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing thrombus removal devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect.

DETAILED DESCRIPTION

[0040] 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.

[0041] Example 1: Please refer to Figure 1-Figure 13 The present invention provides a technical solution: a thrombus removal device, comprising a main body mechanism 1, the main body mechanism 1 comprises a base 11, the front and back sides of the base 11 are fixedly mounted with Velcro 12, and a removal mechanism 2 is arranged above the base 11;

[0042] The removal mechanism 2 includes an auxiliary unit 21 , which is located above the base 11 . The auxiliary unit 21 is used to assist the puncture needle to enter the patient's body.

[0043] As a further definition of the taking-out mechanism 2 of the present invention, the auxiliary unit 21 includes four connecting boxes 2101, the bottom surface of each connecting box 2101 is fixedly connected to the upper surface of the base 11, the interior of each connecting box 2101 is rotatably connected to a first ball screw 2102, the outer surface of each first ball screw 2102 is threadedly connected to a moving column 2103, the outer surface of each first ball screw 2102 is fixedly installed with a first conical wheel 2104, the interior of each connecting box 2101 is rotatably connected to a rotating shaft 2105, and each rotating shaft 2105 is fixedly installed with a second conical wheel 2106 at one end close to the first conical wheel 2104, and the outer surface of each second conical wheel 2106 is threaded with the first conical wheel 2104. The outer surfaces are meshed with each other, and a universal joint 2107 is fixedly installed on the upper surface of each moving column 2103. A placement plate 2108 is fixedly installed on the top of the four universal joints 2107. The universal joint 2107 is a mechanical component used to connect two intersecting axes and transmit power and rotational motion. By rotating the first ball screw 2102 at different positions, different moving columns 2103 can move up and down, thereby adjusting the inclination angle of the placement plate 2108. A rotating disk 2109 is fixedly installed on the end of each rotating shaft 2105 away from the first conical wheel 2104. Four electric push rods 2110 are fixedly installed on the inner bottom wall of the base 11. The telescopic ends of the four electric push rods 2110 are fixedly installed with a connecting plate 2111, which connects Four limit rods 2112 are fixedly installed on the bottom surface of the plate 2111, and the four limit rods 2112 are respectively clamped in the inside of the four rotating disks 2109. The outer surface of the rotating disk 2109 is provided with grooves arranged at equal distances for the limit rods 2112 to extend into, so as to lock the rotating disk 2109. The power provided by the electric push rod 2110 is used to drive the connecting plate 2111 and the limit rods 2112 to move, so as to clamp the limit rods 2112 in the inside of the rotating disk 2109. An electronic inclinometer 2113 is fixedly installed on the upper surface of the placement plate 2108. The electronic inclinometer 2113 detects angle changes based on the principles of gravity and conservation of angular momentum, so that the inclination angle of the placement plate 2108 can be detected. Two installation boxes 2114 are fixedly installed on the upper surface of 08, and two groups of connecting springs 2115 are fixedly installed on the inner walls of the two installation boxes 2114. The number of each group of connecting springs 2115 is two, and a wedge block 2116 is fixedly installed on the end close to each other of each group of connecting springs 2115. The four wedge blocks 2116 are symmetrically distributed in pairs inside the two installation boxes 2114. A pull rod 2117 is fixedly installed on the side of each wedge block 2116 close to the connecting spring 2115, and the end of each pull rod 2117 away from the wedge block 2116 passes through the outside of the installation box 2114. A connecting pipe 2118 is arranged inside the placement plate 2108, and the first fixing rod 2119 is fixedly installed on both sides of the connecting pipe 2118.The two first fixing rods 2119 are respectively clamped in the inside of the two installation boxes 2114, and the bottom surface of each wedge block 2116 is in contact with the outer surface of the first fixing rod 2119. The wedge block 2116 cooperates with the elastic force of the connecting spring 2115 to limit the first fixing rod 2119, so as to facilitate the replacement of different instruments inserted into the patient's body. An auxiliary unit 21 is provided, so that after the medical staff determines the puncture angle according to the imaging data such as angiography, by adjusting the angle of the placement plate 2108, the risk of penetration of the posterior wall of the blood vessel or inadequate puncture caused by angle deviation is reduced. For medical staff with relatively insufficient experience, the auxiliary unit 21 can help the medical staff to complete the thrombus removal operation more accurately.

[0044] See also Figure 4-Figure 5 A sliding rod 2120 is fixedly installed on the inner wall of each connection box 2101, and the outer surface of each sliding rod 2120 is slidably connected to the inner wall of the moving column 2103. The installation of the sliding rod 2120 serves to limit the moving trajectory of the moving column 2103, thereby preventing the moving column 2103 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the moving column 2103.

[0045] See also Figure 7 Four telescopic rods 2121 are fixedly installed on the inner walls of the two installation boxes 2114, and each telescopic rod 2121 is located inside the connecting spring 2115. The telescopic end of each telescopic rod 2121 is fixedly connected to a side of the wedge block 2116 close to the connecting spring 2115. The installation of the telescopic rods 2121 serves to limit the moving trajectory of the wedge block 2116, thereby preventing the wedge block 2116 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the wedge block 2116.

[0046] The specific implementation of this embodiment is as follows: when in use, the medical staff first fixes the base 11 at the position where puncture is required using the Velcro 12, and at the same time exposes the puncture site. Then, the medical staff rotates the corresponding rotating disk 2109 according to the puncture angle determined by the imaging data such as angiography, so that the rotating disk 2109 drives the rotating shaft 2105 to rotate, so that the rotating shaft 2105 drives the second conical wheel 2106 to rotate, and then the second conical wheel 2106 drives the first conical wheel 2104 meshed with it to rotate, so that the first conical wheel 2104 drives the first ball screw 2104 connected to it. 102 is rotated, so that the first ball screw 2102 drives the moving column 2103 threadedly connected thereto to move up and down. During the adjustment process, the medical staff simultaneously adjusts the two diagonal first ball screws 2102 to rotate, so that the two adjusted moving columns 2103 move up and down, while the other two moving columns 2103 do not move up and down, and only the universal joint 2107 changes its angle. Therefore, by changing the height of the two diagonal moving columns 2103 and coordinating with the angle change of the universal joint 2107, the inclination angle of the placement plate 2108 is adjusted, and the two diagonal moving columns 2103 are adjusted. 103, so that one moves upward and the other moves downward. Since the universal joint 2107 can move in any direction, when the two diagonal moving columns 2103 move, the other two diagonal moving columns 2103 are equivalent to an axis. As long as the other two universal joints 2107 rotate, they do not need to move up and down, so the placement plate 2108 will not be twisted. At the same time, when the four moving columns 2103 are locked, the angle of the universal joint 2107 will not change, so it is convenient to fix the puncture angle, so that medical staff can determine the placement plate 2108 by observing the electronic angle meter 2113. The tilt angle is consistent with the puncture angle. The medical staff then turns on the electric push rod 2110 through the external remote control device, and uses the power provided by the electric push rod 2110 to drive the connecting plate 2111 to move downward, so that the connecting plate 2111 drives the limiting rod 2112 to move downward, thereby clamping the limiting rod 2112 inside the rotating disk 2109, and then locking the rotating disk 2109, so that the auxiliary unit 21 assists the medical staff in performing the puncture operation, so that the medical staff can puncture the patient at a more precise tilt angle, avoiding the medical staff from piercing the patient's blood vessels during the puncture process.

[0052] The specific implementation of this embodiment is as follows: before the medical staff fixes the base 11, first remove the film on the release paper 2222, so as to fix the sealing shell 2220 and the rubber sleeve 2221 to the puncture site of the patient, and then the medical staff adjusts the rotating ball 2224 so that the channel on the rotating ball 2224 is consistent with the puncture angle, and at the same time uses the elastic force of the limiting spring 2227 to make the protruding block 2228 clamped in the inside of the limiting groove 2225, so as to limit the rotating ball 2224 to a certain extent. After the medical staff inserts the micro guide wire into the patient's body through the auxiliary unit 21, the medical staff rotates the rotating shaft 2210 so that the rotating shaft 2210 drives the fourth conical wheel 221 1 is rotated, so that the fourth conical wheel 2211 drives the third conical wheel 2209 to rotate, and then the third conical wheel 2209 drives the second ball screw 2208 to rotate, so that the second ball screw 2208 drives the moving plate 2212 to move up and down, so that the height of the first touch switch 2213 is adjusted according to the scale position corresponding to the first pointer 2214 and the first scale 2215, and then the rotating motor 2205 is turned on by the external remote control device, and the power provided by the rotating motor 2205 is used to drive the connecting gear 2206 to rotate, so that the connecting gear 2206 drives the rack plate 2204 to move downward, and then the rack plate 2204 drives the moving plate 2212 to move up and down. The expansion tube 2202 moves downwardly by the block 2203 and the expansion tube 2202. When the expansion tube 2202 moves downwardly, the expansion tube 2202 drives the trigger plate 2207 to move downwardly. When the trigger plate 2207 contacts the first touch switch 2213, the first touch switch 2213 turns off the rotating motor 2205, thereby stopping the extension of the expansion tube 2202, thereby adjusting the length of the expansion tube 2202 extending into the patient's body. After that, the medical staff inserts the first fixing rod 2119 into the installation box 2114. During the process of inserting the first fixing rod 2119 into the installation box 2114, the expansion tube 2202 will pass through the rotating ball 2224 and move therewith to be inserted into the patient's body. The process of adjusting the length of the extension section is outside the patient's body and is not adjusted after insertion, thereby assisting medical staff to insert the expansion tube 2202 into the patient's body at an accurate inclination angle. During the extension of the first fixing rod 2119, the first fixing rod 2119 will push the wedge block 2116 to move to the side close to the connecting spring 2115. When the expansion tube 2202 is inserted, the elastic force provided by the connecting spring 2115 is used to limit the wedge block 2116 to the first fixing rod 2119. When the thrombus is removed, the rotating motor 2205 is used to rotate in the opposite direction, so that the expansion tube 2202 is pulled out at a uniform speed, further preventing the patient's blood vessels from being damaged.

[0053] Example 3: Please refer to Figure 1 and Figure 14-16The present invention provides a technical solution: a thrombus removal device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A puncture mechanism 3 is arranged above the base 11. The removal mechanism 2 is used in conjunction with the puncture mechanism 3. The puncture mechanism 3 is used to adjust the insertion length of the puncture needle.

[0054] As a further limitation of the puncture mechanism 3 of the present invention, the puncture mechanism 3 includes a connecting frame 301, the connecting frame 301 is located above the base 11, and the second fixing rod 302 is fixedly installed on both sides of the connecting frame 301. The third ball screw 303 is rotatably connected inside the connecting frame 301, and a rotating motor 304 is fixedly installed on the upper surface of the connecting frame 301. The output end of the rotating motor 304 passes through the connecting frame 301 and is fixedly connected to the top of the third ball screw 303. The outer surface of the third ball screw 303 is threadedly connected to a limiting frame 305, and a puncture needle body 306 is arranged inside the limiting frame 305. A second scale 307 is fixedly installed on the left side of the connecting frame 301, and a touch plate 308 is fixedly installed on the left side of the limiting frame 305. An electromagnet 309 is fixedly installed on the front of the connecting frame 301, and a mounting plate 310 is arranged on the front of the electromagnet 309. A second touch switch 311 is fixedly installed on the upper surface of the mounting plate 310. The second touch switch 311 is electrically connected to the rotary motor 304 through a wire, so that when the second touch switch 311 is triggered, the rotary motor 304 stops running. A second pointer 312 is fixedly installed on the left side of the mounting plate 310, and a magnet 313 is fixedly installed on the bottom surface of the mounting plate 310. The back of the magnet 313 contacts the front of the electromagnet 309. The attraction between the electromagnet 309 and the magnet 313 is used to fix the mounting plate 310 on the electromagnet 309, so as to facilitate the adjustment of the height of the second touch switch 311. By providing the puncture mechanism 3, the device can assist medical staff to insert the puncture needle body 306 into the patient's body along the specified angle and length by installing the puncture mechanism 3 on the auxiliary unit 21, thereby further avoiding damage to the patient's blood vessels. At the same time, the puncture needle body 306 is pulled out of the patient's body at a uniform speed using the power provided by the rotary motor 304, further avoiding damage to the patient's blood vessels.

[0055] See also Figure 14-16 A limiting column 314 is fixedly installed on the inner wall of the connecting frame 301, and the inner wall of the limiting column 314 is slidably connected to the inner wall of the limiting frame 305. The installation of the limiting column 314 plays a role in limiting the moving trajectory of the limiting frame 305, thereby ensuring the stability of the movement of the limiting frame 305.

[0056] The specific implementation of this embodiment is as follows: during the puncture of the patient, the medical staff first adjusts the second pointer 312 to correspond to the scale on the second scale 307 according to the puncture depth, and then turns on the electromagnet 309, and uses the attraction between the electromagnet 309 and the magnet 313 to set the mounting plate 310 at the corresponding height, and then uses the power provided by the rotating motor 304 to drive the third ball screw 303 to rotate, so that the third ball screw 303 drives the limit frame 305 to move downward, and the limit frame 305 drives the touch plate 308 to move downward. When the touch plate 308 contacts the second touch switch 311, the operation of the rotating motor 304 is stopped, and then the medical staff inserts the second fixing rod 302 into the interior of the mounting box 2114, and uses the wedge block 2116 to rotate. The second fixing rod 302 is limited, and then the medical staff passes the puncture needle body 306 through the limiting frame 305 and inserts it into the patient's body. When the puncture needle body 306 is clamped in the limiting frame 305, the insertion of the puncture needle body 306 is stopped, thereby achieving the purpose of controlling the insertion depth of the puncture needle body 306. Then the medical staff passes the micro guide wire through the puncture needle body 306 and inserts it into the patient's body. Then the medical staff makes the rotating motor 304 rotate in the opposite direction, so that the rotating motor 304 cooperates with the third ball screw 303 and the limiting frame 305 to pull the puncture needle body 306 out of the patient's body at a constant speed. Then the medical staff pulls the pull rod 2117 to one end away from each other, thereby pulling the second fixing rod 302 out of the inside of the installation box 2114, thereby facilitating the medical staff to perform subsequent thrombus removal operations.
