Description

Technical Field

[0001] This utility model relates to the field of microwave ablation electrode technology, specifically a high-performance microwave ablation electrode equipped with a magnetic navigation device. Background Technology

[0002] Ablation therapy has become a hot topic in medical treatment both domestically and internationally. Electromagnetic waves generated by microwave, radiofrequency, or other devices are applied to the treatment site via ablation electrodes. Ablation therapy is mainly used in medical fields such as cardiovascular medicine, oncological surgery, otolaryngology, and orthopedics. Currently, ablation electrodes are primarily solid electrodes, used to remove solid tumors, herniated discs, and nerve blocks. When existing ablation electrodes are applied to bleeding blood vessels, hemangiomas, or tissues with localized fluid, fluid or blood may seep out from the ablation site; this fluid is typically removed from the skin using cotton swabs. Microwave ablation therapy is a treatment method that is highly efficient, rapid, and uniformly heats tumor tissue, provides thorough thermal coagulation, is convenient to use, and safe, and has been widely used in clinical practice for many years.

[0003] Application number CN201320763034.7 discloses an intelligent microwave ablation electrode, comprising a microwave radiation needle, a microwave ablation electrode blade, a temperature measuring device, a handle, a cooling system, and an intelligent input / output device. This invention features automatic blade testing: automatically testing water circulation and microwave output before surgery; and an intelligent safety alarm: automatically cutting off power and stopping the procedure if a malfunction occurs during surgery. However, this application has some inconveniences in practical use, such as: the entire cooling system cannot be placed arbitrarily, and the coolant device cannot be reconnected once it runs out.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A high-performance microwave ablation electrode with a magnetic navigation device includes a treatment mechanism, a cooling mechanism, and a replacement mechanism. The treatment mechanism includes a handle, an ablation needle penetrating one end of the handle, and a radio frequency generator embedded at the other end of the handle. The ablation needle is electrically connected to the radio frequency generator. The cooling mechanism includes an annular cooling cavity inside the handle, two circulating water pipes communicating with the interior of the annular cooling cavity, a first saline bottle inserted into the outer end of the circulating water pipes, a first housing movably fitted onto the outside of the first saline bottle and fixed to the outer wall of the handle, and a micro pump installed on the circulating water pipe near the front of the handle.

The insertion end of the diversion water pipe is located in front of the second saline bottle.

[0007] By adopting the above technical solution, when the saline in the first saline bottle at the front of the handle is used up, the diversion tube is connected to the second saline bottle, and the saline is successfully replenished. Then, the positions of the two saline bottles at the front and back of the handle are swapped to ensure that the saline does not overflow, so that the cooling operation can be seamlessly connected.

[0008] In a preferred embodiment, this invention can be further configured such that two circulating water pipes are vertically symmetrical about the ablation needle, and both the circulating water pipes and the branch water pipes are made of flexible tubing.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1.

[0023] 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.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-performance microwave ablation electrode equipped with a magnetic navigation device.

[0026] Example 1:

[0027] Combination Figure 1-4 As shown, the present invention provides a high-performance microwave ablation electrode with a magnetic navigation device, including a treatment mechanism 100, a cooling mechanism 200 and a replacement mechanism 300. The treatment mechanism 100 includes a handle 110, an ablation needle 120 passing through one end of the handle 110, and a radio frequency generator 130 embedded in the other end of the handle 110. The ablation needle 120 is electrically connected to the radio frequency generator 130.

[0028] Cooling mechanism 200 includes an annular cooling cavity 210 opened inside the handle 110, two circulating water pipes 220 communicating with the inside of the annular cooling cavity 210, a saline bottle 230 inserted into the outer end of the circulating water pipe 220, a sleeve 240 movably sleeved on the outside of the saline bottle 230 and fixed to the outer wall of the handle 110, and a micro pump 250 installed on the circulating water pipe 220 near the front of the handle 110.

[0029] The replacement mechanism 300 includes a second housing 310 installed on the other side of the handle 110, a second saline bottle 320 that is attached to the inner wall of the second housing 310, and a diversion pipe 330 connected to a circulating water pipe 220 near the front of the handle 110. The insertion end of the diversion pipe 330 is located in front of the second saline bottle 320.

[0030] Furthermore, the two circulating water pipes 220 are vertically symmetrical about the ablation needle 120. Both the circulating water pipe 220 and the diversion water pipe 330 are made of flexible tubing. The flexible tubing 220 and the diversion water pipe 330 can be flexibly bent. Fang Bin, the operator, uses this product.

[0031] Furthermore, the diversion water pipe 330 is internally connected to the circulating water pipe 220 near the front of the handle 110. This structural design ensures that the diversion water pipe 330 can draw saline from the saline bottle 320.

[0032] Example 2:

[0033] Combination Figure 1 and Figure 3 As shown, based on Embodiment 1, two housings 240 are located on the front and rear sides of the handle 110, respectively. The housings 240 are made of plastic material. The housings 240 made of plastic material are lightweight and can reduce the load on the operator's hands from the handle 110.

[0034] Example 3:

[0035] Combination Figure 1 and Figure 3-4 As shown, in the above embodiments, the physiological saline bottle 230 and the physiological saline bottle 320 have the same structure. This structural design facilitates the manufacturing of this product.

[0036] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the operator holds the handle 110 and starts the radio frequency generator 130 to complete the ablation needle 120 to kill the lesion. During this period, the micro pump 250 is started, and the circulating water pipe 220 connected to the micro pump 250 draws out the saline bottle 230 at the front of the handle 110. The saline then flows through the annular cooling chamber 210 and then flows into the saline bottle 230 connected to it from the circulating water pipe 220 near the rear of the handle 110. When the saline in the saline bottle 230 is used up, the diversion pipe 330 is connected to the second saline bottle 320, and the saline is successfully replenished. Then, the positions of the two saline bottles 230 at the front and rear of the handle 110 are reversed to ensure that the saline does not overflow, so that the cooling operation can be seamlessly connected.

[0037] 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.
