Preferably, a first through hole is formed in one end, away from the needle head, of the needle tube, one end, away from the moving plate, of the guide plate penetrates through the first through hole, and a second through hole is formed in the side wall of one side of the first through hole.

Preferably, the inside sliding sleeve of second through-hole is equipped with the gag lever post, and the one end of gag lever post extends to second through-hole outside and is fixed with the fixed plate, and sets up perpendicularly between fixed plate and the gag lever post.

Preferably, the limiting rod extends to the outer side wall of the second through hole and is sleeved with a return spring.

Preferably, a plurality of limiting grooves are formed in the side wall of one side of the guide plate, and the limiting grooves and the limiting rods are clamped.

Compared with the prior art, the invention has the beneficial effects that:

1: through the matching among the arranged needle head, the needle tube, the movable plate, the drainage hole, the reinforcing head, the movable plate, the fixed plate, the limiting rod and the reset spring, the needle head can be slightly bent during puncture and can enter the mirror to puncture scar tissues, and the hardness reinforcement of the needle head through the reinforcing head can be realized during medicine injection, so that the situation that the needle head is difficult to bear force is avoided;

2: through the matching of the arranged liquid inlet pipe and the control valve, the injection of the medicine can be facilitated;

the reinforcing head can be used for slightly bending the needle head during puncture, can enter the mirror to puncture scar tissues, can be used for carrying out hardness reinforcement on the needle head through the reinforcing head during medicine injection, avoids the phenomenon that the needle head is difficult to bear force, and can facilitate medicine injection.

Drawings

Fig. 2 is a schematic structural view of a fixing plate and a needle tube of an injection needle for intraurethral injection of scar-prevention drugs according to the present invention.

In the figure: the device comprises a needle head 1, a needle tube 2, a moving plate 3, a reinforcing head 4, a drainage hole 5, a guide plate 6, a pull plate 7, a limiting groove 8, a limiting rod 9, a pull plate 10, a return spring 11, a liquid inlet tube 12 and a control valve 13.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, a syringe needle for intraurethral injection scar prevention medicine, including syringe needle 1, the one end of syringe needle 1 is connected with needle 2, sliding connection has movable plate 3 between the both sides inner wall of needle 2, one side that movable plate 3 is close to syringe needle 1 is fixed with anchor head 4, and anchor head 4 and syringe needle 1 phase-match, one side lateral wall that movable plate 3 kept away from anchor head 4 is fixed with the deflector 6 of perpendicular setting, the one end that movable plate 3 was kept away from to deflector 6 extends to needle 2 external fixation and has arm-tie 7, the lateral wall of needle 2 is fixed with the feed liquor pipe 12 of a plurality of symmetry settings, be connected with control valve 13 on the feed liquor pipe 12.

A plurality of drainage holes 5 are formed in the movable plate 3, a first through hole is formed in one end, away from the needle head 1, of the needle tube 2, one end, away from the movable plate 3, of the guide plate 6 penetrates through the first through hole, a second through hole is formed in one side wall of the first through hole, a limiting rod 9 is sleeved on the inner sliding sleeve of the second through hole, one end of the limiting rod 9 extends to the second through hole and is externally fixed with a fixing plate 10, the fixing plate 10 and the limiting rod 9 are perpendicularly arranged, the limiting rod 9 extends to the outer side wall of the second through hole and is sleeved with a reset spring 11, a plurality of limiting grooves 8 are formed in one side wall of the guide plate 6, and the limiting grooves 8 and.

The working principle is as follows: when the needle enters the mirror, the fixed plate 10 is pulled, the fixed plate 10 drives the limiting rod 9 to be separated from the limiting groove 8, then the pull plate 7 is pulled, the pull plate 7 drives the moving plate 3, the moving plate 3 drives the reinforcing head 4 to be separated from the inner side wall of the needle 1, so that the reinforcing head 4 enters the needle tube 2, finally the fixed plate 10 is loosened, under the elastic action of the reset spring 11, the limiting rod 9 and the limiting groove 8 are clamped and arranged to limit the fixed head 4, then the needle 1 is punctured, when the scar tissue is punctured and the injection of the medicine is needed, the fixed plate 10 is pulled again, so that the limiting rod 9 is separated from the limiting groove 8, the pull plate 7 is pushed, the guide plate 6 is driven by the pull plate 6 to drive the moving plate 3 to move, the moving plate 3 drives the reinforcing head 4 to enter the needle 1, the hardness of the needle 1 is increased, the control valve 13 is opened, and then the medicine, this design is simple swift, can puncture when, and the syringe needle can be crooked a little, can get into the mirror and puncture scar tissue, can carry out hardness reinforcement to the syringe needle through consolidating the head when injecting the medicine, avoids appearing the syringe needle and is difficult to the atress, can make things convenient for the medicine to inject moreover.
