[0030] As shown in FIG. 1 , the present application provides an automatic injection varicose vein medical glue surgical system 100 , comprising an automatic glue injection component 10 , a withdrawal component 20 , a pressing component 30 and a control device 40 .

[0031] The automatic glue injection assembly 10 is used to inject medical glue (hereinafter referred to as glue injection) into the glue injection part of the human body through the glue injection tube 50. As shown in Figures 2 to 4, the automatic glue injection assembly 10 includes an injection motor 110, a first linear drive mechanism 120, a syringe 130 and an injection bar 140. The injection motor 110 drives the injection bar 140 to move through the first linear drive mechanism 120. When the injection bar 140 moves along the first direction X, it can push the injection push rod 131 of the injection motor 110 to inject glue. The injection port of the syringe 130 is used to connect the glue injection tube 50.

[0032] The retraction assembly 20 is used to retract the glue injection tube 50 during glue injection to control the glue injection amount. As shown in Figures 1, 2 and 5, the retraction assembly 20 includes a retraction motor 210, a second linear drive mechanism 220 and a traction structure 230. The retraction motor 210 drives the traction structure 230 to move through the second linear drive mechanism 220, and the traction structure 230 is used to connect and drive the glue injection tube 50 to move.

[0033] As shown in Fig. 1, Fig. 6 to Fig. 8, the pressing assembly 30 is used to press the injection site. The pressing assembly 30 includes a moving motor 310, a third linear drive mechanism 320 and a pressing mechanism 330. The moving motor 310 drives the pressing mechanism 330 to move through the third linear drive mechanism 320, and the pressing mechanism 330 is used to press the injection site.

[0034] As shown in Fig. 1 to Fig. 3, the control device 40 is electrically connected to the injection motor 110, the retraction motor 210 and the moving motor 310. The control device 40 is configured as follows: the control device 40 controls the injection motor 110, the retraction motor 210 and the moving motor 310 to work, wherein in response to the injection motor 110 driving the injection bar 140 to move along the first direction X, the retraction motor 210 drives the traction structure 230 to move along the second direction Y, and the moving motor 310 drives the pressing mechanism 330 to move along the second direction Y, and the second direction Y is opposite to the first direction X.

[0035] The first linear drive mechanism 120 , the second linear drive mechanism 220 , and the third linear drive mechanism 320 may be any mechanism capable of converting rotational motion into linear motion, such as a rack and pinion structure, a worm gear mechanism, and the like.

[0036] Specifically, the first linear drive mechanism 120 is in transmission connection with the motor shaft of the injection motor 110 and the injection bar 140, and converts the rotational motion of the motor shaft of the injection motor 110 into the linear motion of the injection bar 140 in the first direction X. The injection bar 140 can push the injection push rod 131 of the injection motor 110 to move along the first direction X for glue injection. The second linear drive mechanism 220 is in transmission connection with the motor shaft of the withdrawal motor 210 and the traction structure 230, and converts the rotational motion of the withdrawal motor 210 into the linear motion of the traction structure 230 in the second direction Y, and then the traction structure 230 drives the glue injection tube 50 to move. The third linear drive mechanism 320 is in transmission connection with the moving motor 310 and the pressing mechanism 330, so that the pressing mechanism 330 moves along the second direction Y, so that the new glue injection position can be continuously pressed.

[0037] In the present application, when the injection motor 110 drives the injection strip 140 to move along the first direction X, the control device 40 simultaneously controls the withdrawal motor 210 to drive the traction structure 230 to move along the second direction Y, and simultaneously controls the moving motor 310 to drive the pressing mechanism 330 to move along the second direction Y. The control device 40 enables the injection motor 110, the withdrawal motor 210, and the moving motor 310 to be coordinated and controlled to realize the automation of varicose vein surgery; thereby, the injection amount and the tube withdrawal speed are stabilized, and the injection site can be pressed evenly and in a timely manner.

[0038] In some embodiments, as shown in FIG. 2 and FIG. 3 , the control device 40 includes a control box 410 and a main control board 420 disposed in the control box 410. The main control board 420 is electrically connected to the injection motor 110, the retraction motor 210, and the moving motor 310. The automatic glue injection assembly 10 and the retraction assembly 20 are both installed in the control box 410. The control box 410 is an installation carrier of the main control board 420, and also serves as an installation carrier of the injection assembly and the return assembly, which simplifies the structure of the system.

[0039] In some embodiments, as shown in FIGS. 1 to 3 , the syringe 130 is removably fixed to the top of the control box 410. The top of the control box 410 is provided with a first guide groove 411 along the first direction X. The first linear drive mechanism 120 includes an injection gear 121 and an injection rack 122 located in the control box 410, and the injection gear 121 is drivingly connected to the injection motor 110. The injection rack 122 is meshed with the injection gear 121; the injection bar 140 is connected to the injection rack 122, and the injection bar 140 is inserted into the first guide groove 411 and located on one side of the injection push rod 131.

[0040] The syringe 130 is removably fixed to the top of the control box 410, so that after all the medical glue in the syringe 130 is pushed out, the syringe 130 can be replaced to perform the next operation. Optionally, a card slot is provided on the top of the control box 410, and the syringe 130 is removably fixed in the card slot.

[0041] The injection gear 121 and the injection rack 122 are hidden inside the control box 410. The length direction of the injection rack 122 is parallel to the first direction X. The bottom end of the injection bar 140 is connected to the end of the injection rack 122, and the top end of the injection bar 140 is located above the control box 410. The injection and injection rack 122 can be formed into an integral structure, or an assembled structure.

[0042] As shown in Fig. 2, the top of the injection bar 140 is located on the right side of the injection push rod 131 of the injector 130. When the injection bar 140 moves along the first direction X, the injection bar 140 pushes the injection push rod to move to the left side, thereby performing glue injection.

[0043] In some embodiments, as shown in FIG. 2 , FIG. 3 and FIG. 5 , in the retraction assembly 20, the second linear drive mechanism 220 includes a retraction gear 221 and a retraction rack 222 located in the control box 410, the retraction gear 221 is drivingly connected to the retraction motor 210, and the retraction rack 222 is meshed with the retraction gear 221; the traction structure 230 is connected to the retraction rack 222 and extends out of the top of the control box 410. The retraction gear 221 and the retraction rack 222 are hidden inside the control box 410. The traction structure 230 extends out of the control box 410. A second guide groove 412 is provided on the top of the control box 410 for the traction structure 230 to pass through.

[0044] In this embodiment, the type of the traction structure 230 is not limited, as long as it can be connected to the glue injection tube 50 to drive the glue injection tube to move along the second direction Y.

[0045] Specifically, the traction structure 230 includes a clamping groove 231 for clamping the injection tube 50. As shown in FIG5 , the traction structure 230 includes a pair of clamping arms 232 arranged at intervals, and the pair of clamping arms 232 are both connected to the ends of the retracting rack 222. The clamping groove 231 is formed between the pair of clamping arms 232. The size of the clamping groove 231 is slightly smaller than the outer diameter of the injection tube 50.

[0046] In other embodiments, the traction structure 230 is, for example, a clamp capable of clamping the glue injection tube 50 .

[0047] In some embodiments, as shown in FIGS. 6 to 8 , the pressing assembly 30 further includes a base 340 and a control box 350. The moving motor 310 and the pressing mechanism 330 are fixed to the control box 350. The third linear drive mechanism 320 includes a guide rail 321, a moving gear 322, and a moving rack 323, wherein the guide rail 321 is fixed to the base 340 and is relatively movable with the control box 350, the moving gear 322 is drivingly connected to the moving motor 310, and the moving rack 323 is meshed with the moving gear 322 and fixed to the guide rail 321.

[0048] In this embodiment, when the motor shaft of the moving motor 310 rotates, the moving gear 322 moves along the moving rack 323 and drives the control box 350 to move together. The pressing mechanism 330 is disposed on the control box 350, so as to stably move with the control box 350. The guide rail 321 supports and fixes the moving rack 323 on the one hand, and provides support and guidance for the movement of the control box 350 on the other hand, so that the control box 350 moves smoothly.

[0049] In some embodiments, as shown in Figures 6 and 7, a groove 351 is provided at the bottom of the control box 350, and the moving motor 310 is fixed in the control box 350; the guide rail 321 and the moving rack 323 are inserted into the groove 351; the moving gear 322 is exposed in the groove 351 and is located above the moving rack 323.

[0050] In the above manner, the moving motor 310 and the moving gear 322 are hidden between the control box 350 and the guide rail 321, and can be protected by the control box 350. In addition, the moving gear 322 is located above the moving rack 323, so it can be closely meshed with the moving rack 323 under the action of gravity.

[0051] In some embodiments, as shown in FIG. 6 and FIG. 8 , the pressing mechanism 330 includes an adjusting rod mechanism 331 and a pressing block 332 movably connected to the adjusting rod mechanism 331 via a universal joint 333 .

[0052] The pressing block 332 is used to press the injection site on the human body. The pressing block 332 is movably connected to the adjusting rod mechanism 331 through the universal joint 333, so that the pressing block 332 can adapt to the changes of the human body surface curve.

[0053] The pressing block 332 is detachably connected to the universal joint 333 , and the pressing block 332 can be removed from the universal joint 333 . The pressing block 332 is replaced every time an operation is completed.

[0054] In some embodiments, as shown in FIG6 and FIG8 , the adjustment rod mechanism 331 includes a first vertical rod 3311, a cross rod 3312, and a second vertical rod 3313. The first vertical rod 3311 is fixed to the control box 350. One end of the cross rod 3312 is pivotally connected to the first vertical rod 3311 through a first pivot 3314, and a first fastener 3315 is provided on the first pivot 3314, and the first fastener 3315 is used to lock the cross rod 3312 and the first vertical rod 3311; the other end of the cross rod 3312 is pivotally connected to the second vertical rod 3313 through a second pivot 3316, and a second fastener 3317 is provided on the second pivot 3316, and the second fastener 3317 is used to lock the cross rod 3312 and the second vertical rod 3313. The universal joint 333 is connected to the second vertical rod 3313.

[0055] By providing the first vertical rod 3311 , the horizontal rod 3312 , and the second vertical rod 3313 , the pressing block 332 can be located at one side of the control box 350 , so as not to conflict with the movement of the control box 350 .

[0056] In addition, the cross bar 3312 is pivotally connected to the first vertical bar 3311 and locked by a first fastener 3315, and the cross bar 3312 is pivotally connected to the second vertical bar 3313 by a second pivot 3316 and locked by a second fastener 3317. In this way, the position of the universal joint 333 in space can be adjusted, and then the position of the pressing block 332 can be changed to adapt to patients of different body shapes.

[0057] Optionally, the first fastener 3315 and the second fastener 3317 are both nuts.

[0058] In some embodiments, as shown in FIG. 2 , the automatic injection varicose vein medical glue surgical system 100 further includes a main switch 430 , a foot switch 440 , a gear knob 450 , a retraction switch 460 , a counting screen 470 , and a guide wire 480 .

[0059] Specifically, the main control panel 420 and the injection motor 110, the main control panel 420 and the retraction motor 210, the main control panel 420 and the counting screen 470, the main switch 430 and the main control panel 420, the foot switch 440 and the main control panel 420, the retraction switch 460 and the main control panel 420, and the gear button and the main control panel 420 are connected through a wire 480. Among them, the counting screen 470, the main switch 430, the retraction switch 460, the gear knob 450, etc. are all arranged in the control box 410. The foot switch 440 is arranged on one side of the control box 410.

[0060] The foot switch 440 controls the injection motor 110, the retraction motor 210 and the moving motor 310 through the main control panel 420. The specific operation is to press the foot switch 440 once, and the injection motor 110, the retraction motor 210 and the moving motor 310 each move forward a working angle.

[0061] The gear knob 450 controls the single rotation angle of the injection motor 110, the retraction motor 210, and the movement motor 310 through the main control board 420, thereby controlling the single movement distance of the injection bar 140, the single retraction distance of the traction structure 230, and the single movement distance of the pressing mechanism 330. Different positions of the gear knob 450 correspond to different single retraction distances of the traction structure 230 and single movement distances of the pressing mechanism 330.

[0062] The retraction switch 460 is electrically connected to the control device 40, so that when the retraction switch 460 is activated, the injection motor 110 drives the injection bar 140 to move along the second direction Y, the retraction motor 210 drives the traction structure 230 to move along the first direction X, and the moving motor 310 drives the pressing mechanism 330 to move along the first direction X.

[0063] In the present application, the retraction switch 460 controls the injection motor 110, the retraction motor 210 and the moving motor 310 through the main control board 420. The retraction switch 460 is, for example, a push-type switch. When the retraction switch 460 is pressed once, unlike when the foot switch 440 is activated, the injection motor 110, the retraction motor 210 and the moving motor 310 automatically rotate in their respective opposite directions.

[0064] When the retraction switch 460 is pressed once, the injection motor 110 drives the injection gear 121 to rotate in the opposite direction, and moves the injection bar 140 along the second direction Y. When the injection bar 140 moves in the first guide groove 411 until it touches the control box 410, the injection motor 110 stops rotating. Optionally, when the injection bar 140 touches the control box 410, the torque of the injection motor 110 increases, so that the control device 40 controls the injection motor 110 to stop rotating.

[0065] When the retraction switch 460 is pressed once, the retraction motor 210 drives the retraction gear 221 to rotate in the opposite direction, and moves the retraction rack 222 in the first direction X. When the injection motor 110 stops transferring, the retraction motor 210 stops moving. The moving motor 310 drives the moving gear 322 to move along the moving rack 323 in the first direction X. When the injection motor 110 stops rotating, the moving motor 310 stops moving.

[0066] The counting screen 470 records the working times. The specific operation is to press the foot switch 440 once, and the counting screen 470 automatically accumulates and counts once. At the same time, it automatically calculates the injection amount and withdrawal distance at this time according to the state of the gear knob 450.

[0067] In the non-working state, the injection bar 140 can be manually controlled to move, the rack 222 and the control box 350 can be withdrawn, and moved to a specified position. The injection tube 50 can be provided with a position mark to indicate the position of the traction structure 230 on the withdrawal bar.

[0068] The method of using the automatic injection varicose vein medical glue surgical system 100 of the present application is as follows:

[0069] (1) Check the equipment, connect the power supply after confirming that it is correct, and turn on the main switch 430.

[0070] (2) Based on the preoperative evaluation, calculate the approximate injection volume and the corresponding withdrawal distance after a single injection, and select the appropriate injection and withdrawal parameters using the gear knob 450.

[0071] (3) Use the syringe 130 to extract an appropriate amount of medical glue, and fix the syringe 130 on the control box 410, and manually move the injection bar 140 to make the injection bar 140 contact with the injection push rod 131 of the syringe 130.

[0072] (4) Connect the glue injection tube 50 to the injection port of the syringe 130 , and retract the traction structure 230 on the rack 222 to connect the glue injection tube 50 .

[0073] (5) Insert the injection tube 50 into the body and reach the designated position.
