Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As it is shown on figure 3, give the structural representation of the absorption injection ligation treatment device of the present invention, Fig. 1 and Fig. 2 all gives its sectional view, and the trigger in Fig. 1 is in the state of not pulling, and the trigger in Fig. 2 is pulled to rearmost end state.The absorption injection ligation treatment device of the present invention by gun-shaped body 1, trigger 19, sucker 8, suction nozzle 6, push away circle 7, ejector sleeve 5, accumulator 4, inhale negative pressure pump 3, circuit part and drive mechanism form, sucker 8 is internal is cavity and front opening, the front end of suction nozzle 6 communicates with the internal cavities of sucker 8, the rear end of suction nozzle 6 communicates with the air inlet inhaling negative pressure pump 3, and accumulator 4 is powered to inhaling negative pressure pump 3 by circuit part.When suction negative pressure pump 3 works, the internal cavities in sucker 8 is made to produce negative pressure by suction nozzle 6, it is achieved to patient's blood stasis or the adsorption of polyp.
Ejector sleeve 5 is positioned at the outer end of suction nozzle 6, and can be along suction nozzle 6 advance the puck.The front end of ejector sleeve 5 fixes with pushing away circle 7, and rear end is connected with pushing block 10；Pushing away the peripheries that circle 7 is positioned at sucker 8, cushion rubber 29 is placed in the periphery of sucker 8, when pushing away circle 7 advance the puck, can be pushed by cushion rubber 29 foremost on sucker 8, it is achieved the set bundle effect to patient's affected area.
As shown in Figure 4 and Figure 5, sets forth in Fig. 1 the partial enlarged drawing in B region in a-quadrant and Fig. 2, shown drive mechanism is made up of pushing block 10, two guide pad 12, tooth bar 13 and spring leaf 34, the rear end of ejector sleeve 5 is connected with pushing block 10, in order to ejector sleeve 5 can be driven to move during pushing block 10 motion.As shown in Figure 7 and Figure 8, give the structural representation of pushing block 10, two guide pads 12 are fixed on the both sides of pushing block 10, the gathering sill 11 matched with pushing block 10 is offered on the inwall of gun-shaped body 1, by gathering sill 11 to the spacing of guide pad 12 and guide effect, it is ensured that pushing block 10 moves along the length direction of ejector sleeve 5 all the time.It is provided with equally distributed upper stopper 15 on the lower surface of shown guide pad 12, the lower stopper 18 matched with upper stopper 15 it is evenly distributed with on the upper surface of gathering sill 11, as shown in Figure 9, give the structural representation that pushing block 10 matches with gathering sill 11, the risers of shown upper stopper 15 backwards, the risers of lower stopper 18 forward, so by the position-limiting action of upper stopper 15 with lower stopper 18, make pushing block 10 advance the puck only, and can not move backwards.
Tooth bar 13 is fixed on the rear of pushing block 10, and the lower surface of tooth bar 13 is provided with multiple promotion tooth 14, promotes the risers of tooth 14 backwards, and inclined plane is forward.Spring leaf 34 is fixed on trigger 19 by screw 36, for the ease of the installation and removal of screw 36, shown trigger 19 offers counterbore 35.Being provided with and limiting stand on trigger 19, spring leaf 34 is positioned at the front of limiting stand, by the position-limiting action of limiting stand so that spring leaf 34 can bend forward, and can not bend backward.Tooth bar 13 be provided above limited block 33, with prevent on tooth bar 13 move.By trigger 19 by pulling foremost to rearmost end, as it is shown in figure 5, give the schematic diagram that trigger 19 promotes a cushion rubber, by the driving to promoting tooth 14 of the upper end of spring leaf 34, pushing block 10 can be made to travel forward, and then drive pushes away circle 7 and pushed by a cushion rubber on sucker 8.
As shown in Figure 6, give schematic diagram during spring leaf 34 return in Fig. 5, after unclamping trigger 19, trigger 19 is under the effect of return spring 20, make spring leaf 34 have ordering about of rearward movement, due to spring leaf 34 and the contact of incline plane promoting tooth 14 being currently at directly over trigger 19, therefore can cross inclined plane, it is repositioned to promote the rear side of tooth 14 risers, in order to the set carrying out next cushion rubber 29 when again pulling trigger 19 is pricked.So, pull a trigger 19 and only overlap one cushion rubber 29 of bundle, solve the drawback in the past controlling set bundle cushion rubber quantity by controlling the rotational angle of trigger 19, use convenient.
In Fig. 1 and Fig. 2, between suction nozzle 6 and suction negative pressure pump 3, it is additionally provided with the storage device that the liquid to the patient's affected area sucked is kept in, to prevent liquid entry in suction negative pressure pump 3, affects it and normally work.Shown storage device is made up of the first reservoir 24 and standby fluid reservoir 28, suction nozzle 6 communicates with the first reservoir 24, first reservoir 24 is communicated by the upper-end part of driving of communicating pipe 25 with standby fluid reservoir 28, inhales negative pressure pump 3 and is communicated by the top of inhaling hose 9 with standby fluid reservoir 28.When there being a small amount of liquid to enter through suction nozzle 6, the first reservoir 24 can realize storing it；But when the amount of liquid of entrance is bigger, the standby fluid reservoir 28 bigger by the first reservoir 24 and volume stores simultaneously.
The front end of shown gun-shaped body 1 is battery compartment 22, is used for depositing accumulator 4, and rear end is handle portion, and suction negative pressure pump 3 and circuit board 2 may be contained within the internal cavities of handle portion, and circuit part is arranged on circuit board 2.The front end of gun-shaped body 1, the periphery of ejector sleeve 5 are provided with multiple illuminating lamp 27, illuminating lamp 27 and suction negative pressure pump 3 are powered by accumulator 4 through circuit part, it is provided with on and off switch 30 on the outer wall of gun-shaped body 1, can the opening and closing state that inhale negative pressure pump 3 and illuminating lamp 27 be controlled by and off switch 30 simultaneously.
Offering two T-shaped on the lateral surface of shown gun-shaped body 1 and fix groove 31, syringe base 32 can snap in be fixed in groove 31 to T-shaped, fixes syringe with realization.
The use process of the absorption injection ligation treatment device being easily manipulated of the present invention is:
As needed Drug therapy, then syringe is placed on syringe base 32, and the front end of syringe is linked together with syringe adapter 26.It is first turned on and off switch 30, illuminating lamp 27 and suction negative pressure pump 3 are started working, and the opening of sucker 8 front end are directed at the affected area of patient, under the suction suction function inhaling negative pressure pump 3, the affected area of patient is sucked in sucker 8, and now the syringe needle in sucker 8 has stretched to affected area.Then pushing syringe injects medicine to the affected area of patient；After drug injection, cocking 19, pushes cushion rubber 29 from sucker 8, it is achieved prick the set of patient's affected area.As patient exists multiple blood stasis, after changing syringe medicine, by cocking 19 sequential therapeutic.
