Second embodiment
As shown in fig. 4 and 5, the present embodiment is different from the first embodiment in the structure of the pressing belt. In the present embodiment, thepressing belt 3 is formed by connecting a plurality ofrollers 32 and oneinflatable bag 31 in series through a connectingstring 33. By means of theroller 32, thepressing belt 3 can be moved forward without loosening the pressing belt, which is very convenient. Theroller 32 may be a sphere, cylinder, spindle, or the like. Theroller 32 may be made of plastic or rubber. Theinflatable bladder 31 may be made of a transparent material having a width of 1 to 6cm, preferably 3cm. In use, theinflatable balloon 31 is positioned over a target vessel to be treated to compress the target vessel. The connectingcord 33 may be a nylon cord or a fabric cord. The connectingcord 33 may be a round cord or a flat belt passing through theroller 32.
One end of the pressing belt 3 (specifically, the connecting rope 33) is provided with amovable buckle 34, and thepressing belt 3 can be unidirectionally tightened when themovable buckle 34 is not pressed, so that thepressing belt 3 is tightly attached to theaffected limb 100; when the livingbuckle 34 is pressed, thepressing belt 3 can be loosened so as to facilitate the removal of thepressing belt 3 from the affectedlimb 100. It should be understood that the livingbuckle 34 may be replaced with other tightening structures, such as a strap tightening buckle.
In this embodiment, theinflatable balloon 31 is connected to aluer 35, theluer 35 being used to connect theair tube 5, theair tube 5 being connected to aluer 41 on thecontrol box 4.
When varicose vein treatment surgery is performed, thepressing belt 3 is sleeved on the position to be treated of the affectedlimb 100 and is tightened, theinflatable air bag 31 is tightly attached to theaffected limb 100, then the operator distributes thetrigger 11 of the gun 1 to inject vascular closure glue into thetarget blood vessel 101, simultaneously triggers the inflation trigger switch, starts the inflator pump, inflates theinflatable air bag 31 to a preset pressure and maintains the preset time (for example, 30 seconds to 3 minutes) so as to press the target blood vessel through thepressing belt 3; theinflated balloon 31 is then depressurized and thepressing belt 3 is moved to the next position by rolling theroller 32, and then the above-described steps of injecting glue, pressing and moving are repeated until the whole target blood vessel treatment is completed. The blood vessel section of injection vascular closure gum is pressed through the inflatable pressing device, the synchronism is high, the force application of an operator is not needed, the vascular pressing stress is even, the vascular closure gum can be uniformly attached to the vascular wall, the closure rate of a target blood vessel is improved, and the treatment effect is good.
Third embodiment
As shown in fig. 6 to 9, the present embodiment is different from the first embodiment in that the width of thepressing belt 3 is relatively large (for example, greater than 20 cm), and theinflatable airbag 31 is configured to be inflatable in segments. Because thepressing belt 3 is wider, a larger range of target blood vessels can be covered, and therefore, only the inflatable air bags corresponding to the target blood vessel sections to be treated are required to be inflated in the treatment process, thepressing belt 3 does not need to move, and the treatment time is greatly saved. It should be understood that fig. 6 shows only oneair tube 5 as an illustration, and that in practical application, the number ofair tubes 5 is the same as the number of segments of theinflatable bladder 31. That is, each segment ofinflatable bladder 31 is in fluid communication with an inflator via arespective gas tube 5.
The width of each section of inflatable air bag is 1-6 cm, preferably 3cm. That is, the length of the target vessel for each treatment was 3cm.
Since the inflatable bladder is inflated in segments, a correspondingsolenoid valve 7 needs to be provided for control. Theelectromagnetic valve 7 is arranged in thecontrol box 4 and is electrically connected with thecircuit board 8. The air inlet of theelectromagnetic valve 7 is in fluid communication with the inflator pump 9, and the air outlet is connected to each segment ofinflatable bladder 31 through a respective air pipe. Preferably, alloutlet pipes 5 may be provided in a sleeve.
As shown in fig. 8 and 9, an airpath distribution block 10 is further provided in the control box, and the airpath distribution block 10 has anair inlet 10a, a total air outlet 10b and a plurality ofair outlets 10c. Theair inlet 10a is connected with the inflator 9 through an air pipe. Theair outlets 10c are connected to the respectiveinflatable bladders 31 through respective air pipes. Asolenoid valve 7 is installed on eachair outlet 10c for controlling the opening and closing of theair outlet 10c. By adopting the airpath distribution block 10, on one hand, connectors can be saved, and on the other hand, theelectromagnetic valve 7 can be conveniently installed.
In order to facilitate the inflation and deflation of the inflatable balloons of the corresponding section, theoperation buttons 43 on thecontrol box 4 further comprise inflatableballoon selection buttons 431, and the inflatableballoon selection buttons 431 are electrically connected with the circuit board.
Since thepressing belt 3 is relatively wide, if the velcro is disposed along the entire width, it may be relatively inconvenient to operate. Therefore, for convenience of operation, the hook andloop fastener 30 on thepressing belt 3 is divided into a plurality of stages (4 stages are shown) to be provided. The width of each section of the magic tape is 3-5 cm. Wherein, two sections of magic subsides 30 are located respectively in pressing the both ends ofarea 3.
In performing the varicose vein treatment surgery, thecompression band 3 is wrapped and fixed on theaffected limb 100, the rear end (the end close to the dispensing gun 1) of thecompression band 3 corresponds to the target blood vessel segment to be treated first, then the operator dispenses thetrigger 11 of the gun 1 to inject the vascular closure glue into thetarget blood vessel 101 while triggering the inflation trigger switch, activates the inflator pump 9, inflates the firstsegment inflation bladder 31 to a preset pressure and holds the preset time (for example, 30 seconds to 3 minutes) to press the target blood vessel by thecompression band 3; then the first section of theinflatable air bag 31 is decompressed, and then the target blood vessels of each section are sequentially injected with glue, and theinflatable air bags 31 of the corresponding sections are inflated, pressed and decompressed until the treatment of all the target blood vessels is completed. The blood vessel section of injection vascular closure gum is pressed through the inflatable pressing device, the synchronism is high, the force application of an operator is not needed, the vascular pressing stress is even, the vascular closure gum can be uniformly attached to the vascular wall, the closure rate of a target blood vessel is improved, and the treatment effect is good.

Themotor 12 and thescrew 13 are installed in thecontrol box 4 and thescrew 13 is connected with an output shaft of themotor 12. Themotor 12 is electrically connected to thecircuit board 8. Themotor 12 may be a servo motor or a stepper motor to achieve precise control of the amount of vascular closure glue. Themotor 12 may be provided with a decelerator. The pushrod attachment block 14 is slidingly engaged on asyringe slot 44 provided on thecontrol box 4. The pushrod connection block 14 has a screw hole screwed with thescrew rod 13 and a catchinggroove 141 for connecting the push rod 151 of thesyringe 15. Thesyringe 15 is detachably mounted in thesyringe slot 44. The shape of thesyringe slot 44 is adapted to thesyringe 15 so that thesyringe 15 can be snapped into thesyringe slot 44. Thesyringe 15 is connected to an injection tube in the catheter assembly 1. It should be appreciated that the automated glue assembly may also employ a pneumatic drive or other configuration of electric drive. Theoperation buttons 43 on thecontrol box 4 further compriseglue injection keys 432, and theglue injection keys 432 are electrically connected with the circuit board. When theglue injection button 432 is pressed, themotor 12 operates to drive the push rod 151 to push forward to inject a predetermined amount of vascular closure glue into a target blood vessel, and then theinflation trigger switch 6 is pressed to realize inflation pressing. It should be appreciated that theglue injection button 432 and the aircharge trigger switch 6 may be ganged or integrated together. For example, theinflation trigger switch 6 may be set to trigger immediately after the glue-injection key 432 is pressed or to trigger after a predetermined time elapses.
In the varicose vein treatment operation, thepressing band 3 is wrapped and fixed on theaffected limb 100, the rear end of thepressing band 3 corresponds to the target vessel segment to be treated first, then the operator presses theglue injection button 432, themotor 12 starts to automatically inject the vascular closure glue into thetarget vessel 101, then presses theinflation trigger switch 4, starts the inflator pump, and inflates the first segment inflation balloon to a preset pressure for a preset time (for example, 30 seconds to 3 minutes) to press the target vessel by thepressing band 3; and then the first section of the inflatable air bag is decompressed, and then the target blood vessels of each section are sequentially injected, and the inflatable air bags of the corresponding sections are inflated, pressed and decompressed until the treatment of all the target blood vessels is completed. The blood vessel section of injection vascular closure gum is pressed through the inflatable pressing device, the synchronism is high, the force application of an operator is not needed, the vascular pressing stress is even, the vascular closure gum can be uniformly attached to the vascular wall, the closure rate of a target blood vessel is improved, and the treatment effect is good.
