Examples

Referring to fig. 1 to 2, the embodiment of the application provides a catgut embedding needle with injection function, including needle body 1 and needle handle 2, wherein, needle body 1 integrated into one piece is on needle handle 2, the inside stock solution chamber 3 that is provided with of needle handle 2, stock solution chamber 3 is used for keeping in injection medicine, for conveniently to the injection medicine of supplementary in stock solution chamber 3, be provided with injection port 11 on the lateral wall of needle handle 2, injection port 11 department threaded connection has end cap 12, when needs supplementary injection medicine, unscrew end cap 12, add injection medicine through injection port 11 to liquid storage chamber 3 in, after injection medicine is supplementary accomplished, with end cap 12 threaded connection in injection port 11, seal injection port 11. The liquid storage cavity 3 is communicated with the needle body 1, and a pushing component for pushing the injection medicine to the acupuncture point through the needle body 1 is arranged in the liquid storage cavity 3.

In one embodiment, to enable bolus injection of an injected drug to an acupoint, referring to fig. 2, the bolus assembly includes a moving piston 4, a wedge sled 5, a wedge pusher 6, and a return spring 10, specifically:

the movable piston 4 is arranged in the liquid storage cavity 3, and the movable piston 4 is in sealing fit with the inner wall of the liquid storage cavity 3, and the movable piston 4 can move along the liquid storage cavity 3 to press out the injection medicine in the liquid storage cavity 3. The wedge-shaped sliding block 5 is fixed on one side of the movable piston 4 away from the needle body 1; as a way of fixedly connecting the wedge-shaped slide block 5 and the movable piston 4, see fig. 2, a T-shaped caulking groove is formed in one end of the movable piston 4 facing the wedge-shaped slide block 5, a T-shaped plug is arranged in one end of the wedge-shaped slide block 5 facing the movable piston 4, and the T-shaped plug is inserted into the T-shaped caulking groove, so that the movable piston 4 and the wedge-shaped slide block 5 are connected, and separation of the two can be effectively prevented.

Further, the wedge-shaped push block 6 is connected with the wedge-shaped slide block 5 by an inclined plane side, the wedge-shaped push block 6 moves along a direction vertical to the long axis of the liquid storage cavity 3, and when the wedge-shaped push block 6 moves transversely, the wedge-shaped push block 6 is connected with the wedge-shaped slide block 5 by the inclined plane side, so that the wedge-shaped slide block 5 is pushed to slide towards one side of the needle body 1 under the drive of the transverse movement of the wedge-shaped push block 6, and the movable piston 4 is driven to extrude injection medicine out of the liquid storage cavity 3.

Of course, in order to operate the wedge-shaped push block 6 to move transversely, as shown in fig. 2, a guide sleeve 8 is integrally formed on the side wall of the needle handle 2, the guide sleeve is vertically arranged with the needle handle 2, the wedge-shaped push block 6 is slidably arranged in the guide sleeve 8, a through hole is formed at the tail end of the guide sleeve 8, the diameter of the through hole is smaller than that of the wedge-shaped push block 6, so that the wedge-shaped push block 6 is limited in the guide sleeve 8 and does not slide out of the guide sleeve 8, a push rod 7 is integrally formed at one end of the wedge-shaped push block 6 far away from the wedge-shaped slide block 5, the push rod 7 extends out of the guide sleeve 8 through the through hole, and a pressing block 9 is integrally formed at the tail end of the push rod 7, and it is conceivable that when a medical staff holds the needle handle 2 with a hand, the push block 9 can be pressed by a thumb, the push rod 7 is linked to push the wedge-shaped push block 6 to move transversely, so that the wedge-shaped slide block 5 can push the movable piston 4 to the side of the needle body 1, and the injection medicine in the liquid storage cavity 3 can be extruded, and the operation of medicine injection can be completed.

It will be appreciated that, in order to reset the movable piston 4, the wedge-shaped slider 5 and the wedge-shaped push block 6 after the injection of the medicine is completed, referring to fig. 2, the reset spring 10 is fixed to the wedge-shaped slider 5 and the end of the liquid storage cavity 3 away from the needle body 1, when the pressing block is pressed down, the movable piston 4 moves toward the needle body 1 side, the reset spring 10 is elongated, when the pressing block is released, the reset spring 10 pulls the wedge-shaped slider 5 together with the movable piston 4 back to the original position, and the wedge-shaped push block 6 is also restored to the original position under the action of the wedge-shaped slider 5.

To sum up, the embodiment of the application provides a catgut embedding needle with injection function, and when using, not only can catgut embedding treatment through needle 1, but also through after filling injection medicine to liquid storage cavity 3, can be when catgut embedding treatment, through pressing briquetting 9, drive push rod 7 and promote wedge ejector pad 6 sideslip to drive wedge slider 5 and drive and remove piston 4 and to needle 1 one side and remove, extrude the injection medicine in the liquid storage cavity 3. Therefore, the effect of simultaneously carrying out the wire embedding treatment and the drug treatment is realized, and the treatment times of patients and the workload of medical staff are reduced.
