Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a microwave closed catheter with a bipolar emission window. Background Technology

[0002] A disposable microwave ablation closure catheter refers to a catheter held in place and inserted through the skin into the lumen of a diseased vein under real-time ultrasound guidance and monitoring. The microwave energy emitted from the tip of the catheter causes the blood vessel to gradually become fibrotic and eventually completely close, thereby achieving the therapeutic goal. Once the catheter is inserted into the human body, it cannot be reused.

[0003] Application number CN202321059823.2 discloses a disposable microwave ablation closed conduit, including a control shell and a water tank. This invention utilizes a cooling pipe, conduit, cooling holes, annular pipe, water inlet pipe, water guide hole, air suction hole, water inlet pipe, air duct, and copper pipe to continuously cool the heat generated by the cooling water during the cooling process, thereby achieving continuous cooling of the conduit and improving cooling efficiency. While this application also has a cooling water heat exchange function, its structural design is very complex, making it difficult to fit into the already intricate conduit structure, thus increasing manufacturing difficulty.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a microwave closed conduit with a bipolar emission window.

[0019] Example 1: Combination Figure 1-4 As shown, the present invention provides a microwave closed conduit with a bipolar emission window, including a conduit mechanism 100 and a heat dissipation mechanism 200. The conduit mechanism 100 includes an outer tube 110, a microwave emission shaft head 120 connected to one end of the outer tube 110, a plurality of wires 130 connected to the microwave emission shaft head 120, and a connector 140 connected between the plurality of wires 130. The outer tube 110 has a cooling cavity 150 inside for insertion of the wires 130. The heat dissipation mechanism 200 includes an isolation sleeve 300 sleeved on the outside of multiple wires 130, two partitions 210 connected between the outer tube 110 and the isolation sleeve 300, a lower channel 220 located at the bottom of the inner cavity of the cooling chamber 150, a connecting channel 230 located at one end of the cooling chamber 150, an upper channel 240 located at the top of the inner cavity of the cooling chamber 150, a sleeve 250 sleeved on the other end of the outer tube 110, and an inlet 260 and an outlet 270 connected and communicating with the sleeve 250. The inlet 260 communicates with the interior of the lower channel 220, and the outlet 270 communicates with the interior of the upper channel 240.

[0020] Furthermore, the length of the partition 210 is less than the length of the cooling chamber 150, and the outer end of the partition 210 is fitted with the inner wall of the sleeve 250. The size design of the partition 210 ensures that the connecting channel 230 can be left in the cooling chamber 150, so that the saline solution can circulate.

[0021] Furthermore, the two partitions 210 are located on the front and rear sides of the isolation sleeve 300 respectively. The two partitions 210 are located on the same horizontal plane. The layout design of the two partitions 210 can make the internal structure of the cooling cavity 150 neat.

[0022] Furthermore, the lower channel 220, the connecting channel 230, and the upper channel 240 are interconnected. This structural design ensures that the saline solution can flow smoothly and that the cooling operation can proceed smoothly.

[0023] Example 2: Combination Figure 3-4 As shown, based on Embodiment 1, multiple conductors 130 are arranged vertically and attached to each other in pairs. This layout design improves the aesthetics of the circuit layout of this device.

[0024] Example 3: Combination Figure 2 As shown, in the above embodiment, an electromagnetic shielding sleeve 400 is movably sleeved on the outside of the isolation sleeve 300. The outer wall of the electromagnetic shielding sleeve 400 is fixedly connected to the inner wall of the cooling cavity 150. The electromagnetic shielding sleeve 400 enables the product to adapt to the electromagnetic environment.

[0025] The working principle and usage process of this utility model are as follows: When this device is put into actual use, multiple wires 130 are connected to an external power supply through a connector 140. Then, the microwave transmitting head 120 is started, and the tumor at the lesion site is ablated. During this process, external saline solution is injected into the lower channel 220 from the inlet 260. The saline solution then flows through the connecting channel 230 and the upper channel 240 to achieve the circulation of the saline solution. Finally, it is discharged from the outlet 270, thereby reducing the heat generated by the microwave transmitting head 120 during operation and preventing the outer sleeve 110 from burning out.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
