Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a puncture temperature measuring needle. Background Art

[0002] Magnetic induction hyperthermia tumor ablation technology is a new ablation technology. This technology introduces magnetic media into the tumor through a puncture needle, and uses an external alternating magnetic field to induce the magnetic media to heat up, thereby achieving the purpose of thermal ablation. High temperature can cause cell apoptosis. After tumor cells apoptosis, phagocytes in the body devour the cell fragments, and the treatment area is gradually replaced by normal tissue.

[0003] In order to ensure the safety of ablation therapy, the temperature of the treatment area needs to be monitored. If the temperature of the magnetic medium is too high, the normal tissue around the tumor will also be heated, causing unnecessary damage.

[0028] Combine the following Figure 1 and Figure 2 A puncture temperature measuring needle provided by the utility model is described. It should be understood that the following description is only an illustrative embodiment of the utility model and does not constitute any particular limitation to the utility model.

[0029] The embodiment of the utility model provides a puncture temperature measuring needle, comprising: a puncture needle 100, the puncture needle 100 is provided with a receiving cavity 110; a temperature measuring element 200, the temperature measuring element 200 is movably arranged in the receiving cavity 110, and the temperature measuring element 200 can be switched between a temperature measuring position and a storage position. For example, the receiving cavity 110 is located in the middle of the puncture needle 100, and its central axis coincides with the central axis of the puncture needle 100.

[0030] In the temperature measuring position, the temperature measuring component 200 can pass through the side wall of the puncture needle 100 and extend to the outside of the puncture needle 100 ; in the storage position, the temperature measuring component 200 can be stored in the accommodating cavity 110 .

[0031] During use, the puncture needle 100 is punctured into the tissue and the temperature measuring element 200 is moved so that the temperature measuring element 200 is switched to the temperature measuring position to detect the temperature at the current position. Subsequently, the temperature measuring element 200 can be switched to the storage position, and after the puncture needle 100 is rotated to a certain angle, the temperature measuring element 200 is switched to the temperature measuring position to detect the temperature at the current position. According to the above operation, the temperature measurement operation at multiple positions can be realized without puncturing the tissue multiple times, thereby reducing tissue damage.

[0032] In one embodiment of the present invention, a temperature measuring hole 120 is provided on the side wall of the puncture needle 100. The temperature measuring hole 120 is matched with the temperature measuring element 200.

[0033] In one embodiment of the present invention, in the temperature measuring position, the temperature measuring member 200 can extend to the outside of the puncture needle 100 through the temperature measuring through hole 120 .

[0034] In another embodiment of the present invention, in the state of the storage position, the end of the temperature measuring component 200 is flush with the inner wall of the accommodating cavity 110 .

[0035] For example, Figure 1 and Figure 2 As shown, a temperature measuring perforation 120 is provided on the side wall of the puncture needle 100. The diameter of the temperature measuring perforation 120 is slightly larger than the diameter of the temperature measuring element 200. When a temperature measuring operation is required, the temperature measuring element 200 is pushed so that the temperature measuring end of the temperature measuring element 200 passes through the temperature measuring perforation 120 and extends to the outside of the puncture needle 100. When the temperature measuring position needs to be switched, the temperature measuring element 200 is pulled so that the temperature measuring end of the temperature measuring element 200 is retracted into the storage cavity, specifically, so that the temperature measuring end of the temperature measuring element 200 is flush with the inner side wall position of the accommodating cavity 110, and the puncture needle 100 is rotated to a corresponding angle and then the temperature measuring element 200 is pushed again so that the temperature measuring end of the temperature measuring element 200 passes through the temperature measuring perforation 120 again and extends to the outside of the puncture needle 100.

[0036] In one embodiment of the present invention, the temperature measurement perforation 120 is arranged obliquely. Figure 1 and Figure 2 As shown, one end of the puncture needle 100 is used to puncture tissue. The temperature measuring element 200 is inserted into the accommodating cavity 110 from the other end of the puncture needle 100. The outer end of the temperature measuring perforation 120 is arranged close to the puncture end of the puncture needle 100, and the inner end of the temperature measuring perforation 120 is arranged away from the puncture end of the puncture needle 100. Therefore, it is convenient for the temperature measuring element 200 to pass back and forth in the temperature measuring perforation 120.

[0037] In one embodiment of the present invention, the puncture temperature measuring needle further comprises a guide structure, which is disposed in the accommodating cavity 110 and is used to provide a puncture guide for the temperature measuring element 200 .

[0038] For example, in one embodiment of the present invention, the guide structure is a guide plate. One end of the guide plate is connected to the inner edge of the temperature measuring through hole 120 , and the guide plate is parallel to the central axis of the temperature measuring through hole 120 .

[0039] For another example, the temperature measuring element 200 is movably arranged in the accommodating cavity 110 along the central axis of the accommodating cavity 110. A guide groove can be provided on the guide plate, and the guide groove is arranged obliquely. One end of the guide groove extends to the inner edge position of the temperature measuring through hole 120, and the other end of the guide groove extends to the central axis position of the accommodating cavity 110. Thus, the guide groove can provide a guide for the temperature measuring element 200 to be inserted.

[0040] In one embodiment of the present invention, the puncture temperature measuring needle also includes a display device, which is connected to the temperature measuring component 200 and is used to display the detection results of the temperature measuring component 200 for medical staff to view.

[0041] The temperature measuring component 200 may be a temperature measuring optical fiber.

[0042] It should be noted that the above embodiment is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention. That is, the temperature measuring element 200 includes but is not limited to a temperature measuring optical fiber.

[0043] In one embodiment of the utility model, the puncture temperature measuring needle further comprises a handheld end. The handheld end is connected to the puncture needle 100. The handheld end is used for medical personnel to hold and perform puncture and temperature measurement operations.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
