[0023] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

The meaning of "multiple" is two or more, unless otherwise specifically limited. The meaning of "several" is one or more, unless otherwise specifically limited.

[0025] As Figures 1 to 3 shown, the CT puncture positioning regulator in an embodiment of the utility model, including fixed seat 1, fixed seat 1 is set to puncture area, and fixed seat 1 is detachably connected with temperature regulating piece 2, and temperature regulating piece 2 is used to adjust the temperature of puncture area.

[0026] Before CT puncture ablation operation is carried out, first, fixed seat 1 is accurately placed in puncture area, and it is ensured that it is stably connected. Fixed seat 1 is fixed by pasting or bandage etc. to adapt to the puncture demand of different parts. Then, temperature regulating piece 2 is installed on fixed seat 1 according to the need. When hot ablation needle or ice ablation needle carries out puncture operation, temperature regulating piece 2 starts to work. If hot ablation needle is used, there is cooling medium, such as low-temperature gas or liquid, in temperature regulating piece 2, and it exchanges heat with puncture area, and the normal tissue around puncture area is cooled at the same time that hot ablation needle works, and the high-temperature influence brought by hot ablation needle is balanced. If ice ablation needle punctures, there is warm medium in temperature regulating piece 2, and the tissue around puncture area is kept at a relatively suitable temperature, avoiding frostbite due to low temperature. In the puncture ablation process, thermometer can be set on temperature regulating piece 2, and the real-time temperature of puncture area is continuously monitored, and the intensity of cooling or heating is adjusted according to the temperature change, to ensure that the temperature of the tissue around puncture area is always maintained within a safe range until the operation is completed, and finally temperature regulating piece 2 and fixed seat 1 are removed from the patient's body.

[0027] In this embodiment, the positioning regulator solves the limitation problem caused by poor temperature control in traditional CT puncture and ablation surgery by setting a temperature regulator, so that the surgery can be performed more safely, the application range of CT puncture and ablation technology is expanded, more patients are provided with reliable treatment options, and the further development of minimally invasive ablation treatment technology is promoted. Secondly, the fixed seat 1 and the temperature adjusting part 2 are detachably connected. On the one hand, the use convenience of the equipment is improved. Before and after the operation, medical staff can quickly complete the installation and disassembly, saving operation time. On the other hand, it is convenient for the maintenance and maintenance of the equipment. When the temperature adjusting part 2 fails or needs to be cleaned, it can be easily disassembled for separate repair or replacement, reducing the overall maintenance cost. Moreover, this design enhances the adaptability of the product. Temperature adjusting parts 2 of different models and functions can be used with the same fixed seat 1 to meet diverse surgical needs. In addition, by adjusting the temperature of the puncture area in real time, the risk of normal tissue burns by heat ablation needles and frostbite by ice ablation needles is effectively reduced, greatly reducing the complications caused by secondary injury after operation, such as tissue inflammation and necrosis, and promoting faster and better recovery of patients after operation.

[0028] In a preferred example, the temperature adjusting part 2 and the fixed seat 1 are connected by a magic tape.

[0029] Specifically, the surface of the fixed seat 1 is pasted with the nap part of the magic tape. The hook part of the magic tape is also installed on the side of the temperature adjusting part 2 corresponding to the connection of the fixed seat 1. When the temperature adjusting part 2 needs to be connected with the fixed seat 1, medical staff only need to accurately align the hook surface of the temperature adjusting part 2 with the nap surface of the fixed seat 1, and then press gently. The hook surface and the nap surface of the magic tape can be tightly attached together to complete the connection of the two. When the temperature adjusting part 2 needs to be replaced or after the operation is completed, it can be quickly separated from the fixed seat 1 by gently peeling off.

[0030] In this embodiment, the tight hooking and pasting of the magic tape can ensure that the temperature adjusting part 2 will not easily loosen or fall off during the operation process, and stably play the role of adjusting the temperature. Secondly, the operation convenience is greatly improved. The quick pasting and separating characteristics of the magic tape enable medical staff to quickly complete the installation and disassembly of the temperature adjusting part 2 before and after the operation. Furthermore, the magic tape allows the position of the temperature adjusting part 2 to be adjusted within a certain range, which can better adapt to the puncture area of different patients and meet diverse surgical needs. Moreover, the cost of the magic tape is relatively low. When the magic tape is damaged during equipment maintenance, the replacement cost is also low, further reducing the overall maintenance cost of the equipment.

[0031] Alternatively, the temperature adjusting part 2 and the fixed seat 1 are connected by a buckle.

[0032] Specifically, the fixing seat 1 is provided with a clamping groove on the supporting leg, and the temperature adjusting part 2 is provided with a buckle matched with the clamping groove. When it is necessary to connect, the medical staff aligns the temperature adjusting part 2 with the fixing seat 1, and then presses gently. The buckle is embedded in the clamping groove and is tightly clamped by the clamping groove, so that the temperature adjusting part 2 is tightly connected with the fixing seat 1. When disassembled, the temperature adjusting part 2 is pulled up, the buckle is separated from the clamping groove, and the temperature adjusting part 2 is taken off from the fixing seat 1.

[0033] In this embodiment, the buckle connection can also provide a firm connection, and ensure that the temperature adjusting part 2 will not easily fall off even if it is subjected to a certain degree of external impact or equipment movement during the operation, providing reliable protection for the smooth progress of the operation. The material and structure design of the buckle make it have high wear resistance and fatigue resistance, and it can withstand multiple installation and disassembly operations without being easily damaged, and has a long service life. At the same time, this connection method also has the advantage of precise positioning, because the matching accuracy of the buckle and the clamping groove is high, the position of the temperature adjusting part 2 is fixed accurately after installation, and the temperature of the puncture area can be adjusted more accurately, improving the safety and effectiveness of the operation. In addition, the operation of the buckle connection is relatively simple, and the medical staff can master it after simple training, which improves the efficiency of the operation preparation work to a certain extent.

[0034] Alternatively, the temperature adjusting part 2 and the fixing seat 1 are connected by adhesive.

[0035] Specifically, the adhesive is selected from medical-grade high-strength and low-allergic reaction adhesives. On the bonding surface of the fixing seat 1 and the temperature adjusting part 2, a layer of adhesive with appropriate thickness is uniformly applied by using a glue coating device. When the temperature adjusting part 2 needs to be installed, it is precisely aligned with the adhesive surface of the fixing seat 1, gently placed and a certain pressure is applied to make the two tightly bonded. When disassembled, the temperature adjusting part 2 is pulled up, the adhesive surface is separated, and the temperature adjusting part 2 and the fixing seat 1 are separated.

[0036] In this embodiment, the adhesive can provide a firm connection, and there is almost no risk of loosening or falling off. During the operation, the position of the temperature adjusting part 2 can be stably maintained to ensure that it can play a stable role. Moreover, this connection method has relatively low cost, and the adhesive is cheap.

[0037] As shown in Figure 1 and Figure 2 In a preferred example, the temperature adjusting part 2 is ring-shaped and filled with a temperature adjusting medium.

[0038] The temperature adjusting part 2 is ring-shaped, which can make the ablation needle pass through the central hole to normally puncture the lesion area, and can balance the temperature of the puncture area. In the inside of the temperature adjusting part 2, the temperature adjusting medium such as nitrogen, water, and ethylene glycol solution is uniformly filled.

[0039] In a preferred example, the temperature regulating medium is a fluid.

[0040] As shown in the figure, the temperature regulating member 2 is provided with a medium input port 201 and a medium output port 202. Figure 1

[0041] Specifically, the medium input port 201 and the medium output port 202 are provided with standard threaded interfaces, which are convenient for connecting with external medium supply equipment and recovery equipment. Before performing CT puncture ablation surgery, the fixing seat 1 is first installed around the puncture area, and then the annular temperature regulating member 2 is connected to the fixing seat 1. When the operation is ready, the medium input port 201 is connected to the temperature regulating medium supply equipment through the connecting pipeline, and the medium output port 202 is connected to the recovery equipment. If a hot ablation needle is used, the low-temperature liquid or gas temperature regulating medium flows into the temperature regulating member 2 from the input port, and in the process of circulating flow, quickly absorbs the heat generated by the hot ablation around the puncture area, and the medium after being warmed up flows out from the output port and enters the recovery equipment for cooling treatment, and then circulates into the temperature regulating member 2 again. If it is a cryoablation needle, the warm medium flows in from the input port, releases heat and flows out from the output port, and is heated again for circulation, so as to effectively regulate the temperature of the puncture area. During the entire operation, the flow rate, temperature and other parameters of the medium supply equipment can be adjusted according to the real-time temperature change of the puncture area, so as to flexibly adjust the temperature regulating effect.

[0042] In this embodiment, by providing the medium input port 201 and the medium output port 202, the temperature regulating medium can be replaced conveniently, so that when the performance of the temperature regulating medium is degraded or contaminated, it can be replaced in time, prolonging the service life of the equipment and reducing the maintenance cost. Through the circulating flow of the medium and the regulation of the temperature and flow rate of the input medium, the temperature change of the puncture area in different operation stages and different ablation modes can be quickly and accurately responded, and the adaptability is stronger than that of the temperature regulating member 2 filled with fixed medium.

[0043] Alternatively, the temperature regulating member 2 is provided with a heating device and / or a refrigeration device inside.

[0044] ​The heating device is a thin film heating sheet, which is light, thin and has high heating efficiency. The thin film heating sheet is evenly distributed on the inner layer of the temperature adjusting member 2 and closely adheres to the temperature adjusting member 2. The refrigeration device is a semiconductor refrigeration sheet, which uses the Peltier effect to achieve refrigeration. The temperature adjusting member 2 is provided with a temperature sensor for real-time monitoring of the temperature of the puncture area. When performing CT puncture ablation surgery, the fixed seat 1 is first stably installed around the puncture area, and then the temperature adjusting member 2 is connected to the fixed seat 1 to ensure that it covers the puncture area. During the operation, the temperature sensor transmits the real-time monitored temperature data to the control system. If a hot ablation needle is used, when the temperature of the puncture area is detected to be too high, the control system will start the semiconductor refrigeration sheet to quickly reduce the temperature inside the temperature adjusting member 2, thereby absorbing the heat around the puncture area. If the temperature is too low, the thin film heating sheet will be started to raise the temperature of the temperature adjusting member 2 to provide heat for the puncture area.

[0045] In this embodiment, by means of the built-in heating and refrigeration devices, once the temperature sensor detects abnormal temperature, the heating or refrigeration device can quickly respond and quickly adjust the temperature to timely respond to temperature changes. The temperature sensor cooperates with the PID temperature control system to accurately control the intensity of heating or refrigeration according to the actual temperature requirement, accurately adjusts the temperature of the puncture area, and effectively avoids damage to the tissue caused by excessively high or low temperature. In addition, the independence of the device is greatly enhanced, and it does not need to rely on external medium supply and recovery equipment, which reduces the complexity and floor area of the device and improves the applicability and stability of the device in different surgical environments.

[0046] As shown in Figure 1 In a preferred example, the temperature adjusting member 2 is provided with a notch 203.

[0047] The notch 203 is provided on one side of the temperature adjusting member 2 to form an open loop. When disassembling, the temperature adjusting member 2 can be separated from the fixed seat 1 by gently applying force from the notch 203, which is convenient for operation and does not need to remove the ablation needle. The presence of the notch 203 makes the installation and disassembly process more easy and efficient, saving the operation time of medical staff.

[0048] As shown in Figures 1 to 3 In a preferred example, the fixed seat 1 is rotationally connected with two mutually perpendicular arc-shaped supports 3, the arc-shaped supports 3 are each provided with a sliding groove 301, the arc-shaped supports 3 are provided with a scale line 302 on the side of the sliding groove 301, and a guide seat 4 is slidingly arranged in the two sliding grooves 301.

[0049] In the embodiment, the scale line 302 is provided to provide an intuitive quantitative basis for the adjustment of the puncture angle, and medical staff can accurately adjust the position of the guide seat 4 in the sliding groove 301 according to the operation requirement by observation, so as to accurately control the puncture angle and effectively avoid operation failure caused by angle deviation. In terms of flexibility, the two mutually perpendicular arc-shaped supports 3 enable the guide seat 4 to be flexibly moved in three-dimensional space, meet the puncture requirement in different directions and at different angles, and improve the flexibility of puncture operation.

[0050] The above merely describes the preferred embodiments of the utility model and is not intended to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
