Referring to fig. 1 to 3, the present embodiment provides a novel needle 1000. The novel needle 1000 includes: a main shaft 100, a sleeve 200, a needle tube 300, and a strut 400.

The sleeve 200 is slidably fitted over the main shaft 100. The main rod 100 has a flow passage 110 through which a medium passes. One end of the needle tube 300 is engaged with the main shaft 100 and is communicated with the flow passage 110. The rod 400 is hinged to the needle tube 300 at one end and to the sleeve 200 at the other end, so that the sleeve 200 can push the needle tube 300 to open and close.

After the new needle 1000 reaches the blood lump after the needle insertion is completed, the needle tube 300 can be opened by pushing the sleeve 200, so that the needle tube 300 is opened relative to the main rod 100, thereby improving the effect of the new needle 1000 in extracting the large and viscous blood lump.

In the extraction process, the extraction may be performed directly through the flow passage 110 of the main rod 100, or may be performed through the main rod 100 using a syringe, but the specific extraction method is not limited thereto.

Overall, the novel needle 1000 has simple structure, simple operation and strong controllability, and can effectively accelerate the blood drawing efficiency. The blood lump extractor has good extraction effect on blood lumps with large volume and high viscosity. Effectively reduces the operation difficulty and complexity and improves the operation efficiency.

In this embodiment, the sleeve 200 and the main rod are coaxially disposed, and the inner wall of the sleeve 200 is attached to the outer wall of the main rod 100, so as to ensure that the sleeve 200 can stably slide along the main rod 100, and the opening and retraction of the needle tube 300 are more stable. The flow passage 110 is coaxially disposed with the main rod 100 and extends in the axial direction of the main rod 100.

Further, the end of the sleeve 200 adjacent to the needle tube 300 has a flange 210, and the flange 210 is formed by protruding the outer wall of the sleeve 200. Strut 400 is hinged to flange 210. In the present embodiment, the needle tubes 300 are provided in plural, and the plural needle tubes 300 are provided at regular intervals in the circumferential direction of the main rod 100. The flanges 210 are continuously arranged along the circumference of the sleeve 200 in a ring shape, and the struts 400 are all hinged to the flanges 210. The plurality of needle tubes 300 can be simultaneously opened in an umbrella shape by driving the cannula 200.

In this embodiment, the needle tube 300 is fixedly connected to the main shaft 100, the needle tube 300 is communicated with the flow passage 110 of the main shaft 100, and the needle tube 300 has elasticity. When the cannula 200 pushes the needle tube 300 to open through the supporting rod 400, the needle tube 300 has elasticity, and the needle tube 300 is generally long and thin, so that the needle tube 300 has very good elasticity and can be smoothly opened without breaking. After withdrawal, the sleeve 200 is repositioned and the needle cannula 300 is reattached to the main shaft 100.

Referring to fig. 4 and 5, in other embodiments of the present invention, the needle cannula 300 and the main shaft 100 may be connected by a connector 500. The connector 500 is wrapped around the end of the main rod 100, and the connector 500 has an inner cavity 510, and the inner cavity 510 is communicated with the flow channel 110. The end of the needle 300 extends through the connector 500 and connects to the connector 500, and the needle 300 communicates with the lumen 510. The connector 500 is made of a flexible material. With this configuration, when the needle tube 300 is pushed open by pushing the sleeve 200, the needle tube 300 is easily deflected due to the local elastic deformation of the connecting member 500 because the connecting member 500 is made of a flexible material. When the needle tube 300 is retracted by pushing the sleeve 200, the elastic deformation of the connector 500 is removed and the needle tube 300 is smoothly retracted. In a natural state, the needle 300 is attached to the main shaft 100. Through this design, can make constantly keep soft connection between needle 300 and mobile jib 100, guarantee the intercommunication effect of the two on the one hand, on the other hand avoids needle 300 to warp.

When the needle tube 300 is connected with the main rod 100 through the connecting member 500, the extension tube 600 may be directly coaxially and fixedly connected with the main rod 100, the extension tube 600 is communicated with the flow passage 110 of the main rod 100, on the basis, the connection part of the extension tube 600 and the main rod 100 is provided with the bypass hole 610, the bypass hole 610 is communicated with the flow passage 110 of the main rod 100, the aperture of the bypass hole 610 is larger than the outer diameter of the needle tube 300, and the plurality of bypass holes 610 are uniformly arranged along the circumferential direction of the main rod 100 at intervals. The end of the syringe 300 extends into the bypass hole 610, and the connector 500 needs to be changed at this time, and the connector 500 is still made of a flexible material, but the connector 500 is disposed differently, where the connector 500 is filled in a gap between the outer wall of the syringe 300 and the inner wall of the bypass hole 610, to function as a coupling of the syringe 300 to the bypass tube. Because connector 500 is flexible, needle cannula 300 is still flexible to extend and retract with respect to main shaft 100. In order to facilitate the manipulation of the needle tube 300, a bent portion 310 may be disposed at an end of the needle tube 300, and the bent portion 310 may be connected to the bypass hole 610, so that the needle tube 300 can be attached to the main rod 100 in a natural state.
