Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a lymphatic puncture needle. Background Technology

[0002] Lymph nodes are distributed throughout the body, and many factors can cause them to swell, such as infections (bacteria, viruses, fungi, filariasis), tuberculosis, hematopoietic system tumors (leukemia, lymphoma), and metastatic tumors. Lymph node aspiration to obtain fluid, followed by cytological or bacteriological examination, can aid in the diagnosis of these diseases.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a lymph node puncture needle, including a puncture needle tube 1, the outer wall of which is provided with a threaded groove 11, a needle tube sheath 2 is sleeved on one end of the puncture needle tube 1, a mounting seat 3 is connected to one end of the needle tube sheath 2, an interface seat 5 is connected to one end of the mounting seat 3, a connector branch 51 is connected to one side of the interface seat 5, and a locking screw seat 7 is provided at one end of the interface seat 5. The threaded groove 11 enables laser-cut threaded grooves to enhance high echo reflectivity and enhance ultrasound imaging. In use, the interface seat 5 is screwed onto the locking screw seat 7, and an injection agent is introduced into the interface seat 5 to enter the puncture needle tube 1 to achieve normal liquid injection. The connector branch 51 enables the injection of two liquids. The needle length is a 5-6cm special length designed for lymph node puncture, and a commercially available Luer connector is used for easy connection with other instruments. The needle body is injection molded from polyetheramide polymer.

[0020] The puncture needle 1 is made of 304 stainless steel. 304 stainless steel has good lubricity and also prevents rust.

[0021] The mounting base 3 has an L-shaped guide groove 31 inside. One end of the L-shaped guide groove 31 passes through the outer wall of the mounting base 3. A drain wire 6 slides through the L-shaped guide groove 31. The drain wire 6 slides in the L-shaped guide groove 31 to guide the movement of the drain wire 6. When it continues to slide deeper, it will enter the inner wall of the puncture needle tube 1 to clear the iodine oil blockage inside.

[0022] A roller bracket 4 is installed on the outer wall of the mounting base 3. A guide roller 41 is rotatably mounted on the roller bracket 4. The unclogging wire 6 is in contact with the guide roller 41. The guide roller 41 guides the movement trajectory of the unclogging wire 6 and prevents the unclogging wire 6 from deviating from the trajectory.

[0023] A sealing ring 8 is installed on the inner wall of the L-shaped guide groove 31. The sealing ring 8 is used to seal the liquid inside the L-shaped guide groove 31 and prevent liquid leakage.

[0024] The mounting base 3 has a liquid channel 32. The lower end of the liquid channel 32 is connected to the L-shaped guide groove 31, and the upper end of the liquid channel 32 is connected to the interior of the interface base 5. The liquid injected enters the L-shaped guide groove 31 and then enters the interior of the puncture needle tube 1 through the liquid channel 32. During normal injection, the distal end of the unblocking wire 6 needs to be pulled out to prevent it from blocking the injection.

[0025] When finished using the drain cleaner 6, pull it out completely and disinfect it separately for easy reuse. The drain cleaner 6 is best pulled by hand, but it can also be connected to other pulling devices to achieve a pulling effect.

[0026] By incorporating threaded grooves and laser-cut threaded grooves to enhance the high echo reflection surface and improve ultrasonic imaging, the 304 stainless steel tube avoids blockage caused by injected iodine oil. In case of blockage, the internal iodine oil can be cleared by repeatedly pulling and pushing the unblocking thread.
