[0002] The Ling Shu large needle, also known as the large needle, is a kind of needle in traditional Chinese medicine acupuncture and belongs to one of the nine ancient needles. The Ling Shu large needle is characterized by a thick and long needle body, and the needle tip is flat and slightly round. When in use, it is inserted into the human body after breaking the skin with a sharp needle. It is mainly used to dredge joint bone bi and the obstruction in the deep layer of the lumbar spine. The flat and slightly round needle tip will not cause damage to important tissues and organs such as human nerves, blood vessels, and muscles.

[0003] For example, a Ling Shu needle disclosed in the authorized announcement number CN212067197U. Medical staff insert the needle tip into the patient's body to perform bi syndrome dredging treatment. However, in the clinical treatment process of some bi syndrome dredging, it is necessary to inject nutrient solution or medicinal liquid into the dredged part to assist the patient's recovery. However, the existing Ling Shu large needles all adopt a solid structure, which can only achieve physical dredging and cannot introduce the nutrient solution or medicinal liquid into the dredged part. It is necessary to use a syringe for liquid injection separately. When injecting separately, it is not easy to control the insertion depth of the syringe needle and it is impossible to accurately insert it into the bi obstruction area. Therefore, it is impossible to ensure that the syringe can directly and accurately inject the nutrient solution or medicinal liquid into the bi obstruction area dredged by the Ling Shu large needle. Moreover, the needle tip of the syringe is very sharp, and it is easy to damage deep nerves, blood vessels and other tissues when injecting separately. Content of the Utility Model

[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required to be used in the embodiments will be briefly introduced below. Obviously, the drawings in the following description are some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0019] Please refer to Figures 1 to 3, an embodiment of the present utility model provides a Ling Shu large needle with a liquid injection function, including a needle body 1 and a needle handle 2 provided at the end of the needle body 1. The needle body 1 is a thick and long structure in a circular or flat shape. The tip of the needle body 1 is in a flat and slightly round shape. A central hole is opened along the length direction inside the needle body 1 to form a liquid medicine drainage channel. An outlet hole 3 is opened at the tip of the needle body 1 away from the needle handle 2 and is communicated with the liquid medicine drainage channel inside the needle body 1. The outlet hole 3 is opened on the side wall of the tip of the needle body 1. A connector 4 for inserting a syringe barrel 8 is provided at the tail of the needle handle 2. The connector 4 is communicated with the liquid medicine drainage channel inside the needle body 1. The syringe barrel 8 is a syringe without a needle head 9 and is used for injecting nutrient solution or liquid medicine. The specification of the connector 4 matches the plug of the syringe barrel 8. The syringe barrel 8 and the connector 4 are in a sealed connection. While dredging the obstruction, the syringe barrel 8 filled with nutrient solution or liquid medicine can be inserted into the connector 4 at the tail of the needle handle 2, and then the syringe barrel 8 is pushed to push the nutrient solution or liquid medicine towards the needle body 1, and it flows through the liquid medicine drainage channel inside the needle body 1 to the outlet hole 3, so that the nutrient solution or liquid medicine is directly discharged from the outlet hole 3 to the dredging part of the human body.

[0020] Please refer to Figure 4 , in a further solution, in order to facilitate the injection operation of a syringe with a needle head 9, a sealing plug 5 is provided inside the connector 4 at the tail of the needle handle 2. The sealing plug 5 is made of a rubber plug or a silicone plug. The sealing plug 5 and the connector 4 are in interference fit to seal the connector 4. The sealing plug 5 is used in cooperation with a syringe with a needle head 9. During the injection operation, the needle head 9 of the syringe can be directly inserted into the sealing plug 5. After the needle head 9 passes through the sealing plug 5, it is inserted into the inside of the connector 4 for injection operation. The sealing plug 5 and the connector 4 are detachably installed. When injecting with a syringe without a needle head 9, the sealing plug 5 can be removed by oneself.

[0021] Please refer to Figure 1 , in order to avoid contamination at the connector 4, a detachable protective cap 6 is sleeved on the connector 4 at the tail of the needle handle 2. The protective cap 6 is connected to the tail of the needle handle 2 by means of screw connection or snap connection and is used to provide sanitary protection for the connector 4.
