[0043] like Figure 1 and Figure 6 As shown, in the first aspect, an embodiment of the present application provides a connector 100 , which relates to the technical field of medical devices, and is mainly used in a therapeutic device 1000 having a position sensor 200 and an ablation gun 300 , and is used to install the position sensor 200 on the ablation gun 300 .

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, the connector 100 provided in this embodiment includes: a fixing portion 110 , a fitting portion 120 , a first elastic clamping portion 130 and a second elastic clamping portion 140 .

[0045] The fixing portion 110 is used to fix the position sensor 200. The fitting portion 120 is connected to one end of the fixing portion 110 and is used to fit on the front end 310 of the ablation gun 300. The first elastic clamping portion 130 is connected to one end of the fixing portion 110 away from the fitting portion 120 and is used to clamp on the rear end 320 of the ablation gun 300. The second elastic clamping portion 140 is connected to the fixing portion 110 and is located between the fitting portion 120 and the first elastic clamping portion 130. The second elastic clamping portion 140 is used to clamp on both sides of the ablation gun 300.

[0046] It should be noted that the fixing portion 110 is used to fix the position sensor 200, which means that the fixing portion 110 can limit the relative movement of the position sensor 200 and the connector 100. The fitting portion 120 is used to fit the front end 310 of the ablation gun 300, which means that the shape of the fitting portion 120 is compatible with the shape of the front end 310 of the ablation gun 300, and the contact between the two is surface contact.

[0047] In the related art, the position sensor is fixed by a connector, and screws are arranged around the connector to fix the connector to the ablation gun, so that the connector and the position sensor are installed on the ablation gun together. However, in the process of installing and removing the connector, a disassembly tool such as a screwdriver is required, which affects the installation efficiency and disassembly efficiency of the position sensor.

[0048] It is understandable that when the connector 100 provided in this embodiment is installed, the fitting portion 120 is fitted to the front end 310 of the ablation gun 300, and the first elastic clamping portion 130 is clamped to the rear end 320 of the ablation gun 300, and the second elastic clamping portion 140 is clamped to both sides of the ablation gun 300, so that the connector 100 and the position sensor 200 are installed on the ablation gun 300 together. When the connector 100 provided in this embodiment is disassembled, it is only necessary to apply a force to the connector 100 so that the fitting portion 120, the first elastic clamping portion 130 and the second elastic clamping portion 140 are separated from the ablation gun 300 respectively, so that the connector 100 and the position sensor 200 can be disassembled from the ablation gun 300 together. Since the connector 100 provided in this embodiment does not need to be installed and disassembled with the aid of a disassembly tool, the operation process is more convenient and quick, thereby improving the installation efficiency and disassembly efficiency of the position sensor 200.

[0049] like Figure 2 and Figure 3 As shown, in one embodiment, the second elastic clamping portion 140 includes a first elastic arm 141 and a second elastic arm 142, the fixing portion 110 is connected between the first elastic arm 141 and the second elastic arm 142, the first elastic arm 141 is used to clamp on one side of the ablation gun 300, and the second elastic arm 142 is used to clamp on the other side of the ablation gun 300.

[0050] In this embodiment, since the first elastic arm 141 is clamped on one side of the ablation gun 300 and the second elastic arm 142 is clamped on the other side of the ablation gun 300, that is, the connector 100 is clamped on both sides of the ablation gun 300 by the first elastic arm 141 and the second elastic arm 142 respectively, a better supporting effect can be formed, so that the connector 100 is stably installed on the ablation gun 300.

[0051] like Figure 3 and Figure 4As shown, further, the first elastic arm 141 and / or the second elastic arm 142 includes a first curved segment 1421 and a second curved segment 1422, one end of the first curved segment 1421 is connected to the fixed portion 110, and the second curved segment 1422 is connected to an end of the first curved segment 1421 away from the fixed portion 110.

[0052] It should be noted that the first elastic arm 141 and / or the second elastic arm 142 including the first curved segment 1421 and the second curved segment 1422 means that at least one of the first elastic arm 141 and the second elastic arm 142 includes the first curved segment 1421 and the second curved segment 1422 .

[0053] In this embodiment, since at least one of the first elastic arm 141 and the second elastic arm 142 includes a first curved segment 1421 and a second curved segment 1422, one end of the first curved segment 1421 is connected to the fixing portion 110, and the second curved segment 1422 is connected to an end of the first curved segment 1421 away from the fixing portion 110. In this way, by clamping the first curved segment 1421 and the second curved segment 1422 on the ablation gun 300 respectively, a better supporting effect can be formed, so that the connector 100 is installed on the ablation gun 300 more stably.

[0054] Furthermore, the first curved section 1421 is used for surface contact with the ablation gun 300 , and the second curved section 1422 is used for line contact with the ablation gun 300 .

[0055] In this embodiment, compared with the point contact method, the connector 100 can be more stably installed on the ablation gun 300 by surface contact with the ablation gun 300 through the first curved section 1421 and line contact with the ablation gun 300 through the second curved section 1422.

[0056] like Figure 3 As shown, further, the first elastic arm 141 and the second elastic arm 142 are respectively provided with multiple, that is, the first elastic arm 141 is provided with multiple, the second elastic arm 142 is provided with multiple, two adjacent first elastic arms 141 are arranged at intervals, and two adjacent second elastic arms 142 are arranged at intervals.

[0057] For example, the number of the first elastic arms 141 or the second elastic arms 142 may be two, three, four, five, etc., which is not specifically limited herein.

[0058] In this embodiment, since there are multiple first elastic arms 141 and second elastic arms 142 respectively, two adjacent first elastic arms 141 are arranged at intervals, and two adjacent second elastic arms 142 are arranged at intervals, multiple groups of spaced-apart supporting forces can be formed, so that the connector 100 can be more stably installed on the ablation gun 300.

[0059] In another embodiment, the second elastic clamping portion 140 may also adopt the form of the above-mentioned fitting portion 120, that is, the second elastic clamping portion 140 is an elastic arc-shaped fitting plate, and the elastic arc-shaped fitting plate can also be clamped on both sides of the ablation gun 300, and the arc-shaped fitting plate can fit with the ablation gun 300, that is, the two are in surface contact, so as to achieve a better clamping and stabilizing effect. No specific restriction is made on the structure of the second elastic clamping portion 140 herein.

[0060] like Figure 3 and Figure 4 As shown, in one embodiment, the first elastic clamping portion 130 includes a connecting section 131 and a third curved section 132 , the connecting section 131 is connected between the fixing portion 110 and the third curved section 132 , and the third curved section 132 is used for line contact or surface contact with the rear end 320 of the ablation gun 300 .

[0061] In this embodiment, the connection section 131 is provided to facilitate the mutual connection between the first elastic clamping portion 130 and the fixing portion 110. Compared with point contact, the line contact or surface contact between the third curved section 132 and the rear end 320 of the ablation gun 300 can form a better support effect.

[0062] In another embodiment, the first elastic clamping portion 130 may also adopt the design of the elastic arm and the bending section of the second elastic clamping portion 140 , and no specific limitation is imposed on the structure of the first elastic clamping portion 130 .

[0063] like Figure 1 and Figure 2 As shown, in one embodiment, the first elastic clamping portion 130 is used to clamp at a groove 321 provided at the rear end 320 of the ablation gun 300 .

[0064] In this embodiment, the first elastic clamping portion 130 is accommodated by the groove 321 , which can limit the first elastic clamping portion 130 , so that the first elastic clamping portion 130 can be clamped on the rear end 320 of the ablation gun 300 more stably.

[0065] like Figure 4 and Figure 5As shown, in one embodiment, the fixing part 110 includes a base 111 and a flip cover 112, the base 111 is connected to the fitting part 120, the first elastic clamping part 130 and the second elastic clamping part 140 respectively, a connecting piece 1111 is provided on the base 111, and an open cavity 1113 for placing the position sensor 200 is defined, and a waist hole 1112 is opened on the connecting piece 1111. A rotating shaft 1121 is provided on one side of the flip cover 112, and the rotating shaft 1121 is movably arranged in the waist hole 1112, and an elastic clamping piece 1122 is provided on the side of the flip cover 112 away from the rotating shaft 1121, and a limiting piece 1114 adapted to the elastic clamping piece 1122 is provided on the base 111, and the limiting piece 1114 is located in the open cavity 1113.

[0066] like Figure 6 As shown, when the flip cover 112 moves to the first preset position relative to the base 111 in the preset direction x, the elastic clamping member 1122 is clamped with the limiting member 1114, and the flip cover 112 is locked on the base 111. Figure 7 As shown, when the flip cover 112 moves to the second preset position relative to the base 111 in the preset direction x, the elastic clamping member 1122 separates from the limiting member 1114, and the flip cover 112 can rotate relative to the base 111 around the rotation axis 1121. Through the above design, medical personnel can more conveniently and quickly install or remove the position sensor 200 from the connector 100, thereby improving the installation efficiency and removal efficiency of the position sensor 200.

[0067] like Figure 5 and Figure 8 As shown, further, the limiting member 1114 includes a first limiting rib 11141 and a second limiting rib 11142, the second limiting rib 11142 is limited to an L shape and is arranged around the first limiting rib 11141, the elastic clip 1122 includes a first elastic segment 11221 and a second elastic segment 11222 connected to each other, and the second elastic segment 11222 is provided with a clip groove 11223 adapted to the shape of the first limiting rib 11141.

[0068] Exemplarily, the card groove 11223 can be a V-shaped groove, a rectangular groove, an arc groove, etc.

[0069] like Figure 6 As shown, when the flip cover 112 moves to the first preset position relative to the base 111 in the preset direction x, the first limiting rib 11141 is inserted into the slot 11223, and the second limiting rib 11142 can abut against the second elastic section 11222. Figure 7As shown, when the flip cover 112 moves to the second preset position relative to the base 111 in the preset direction x, the first limiting rib 11141 slides out of the slot 11223. Through the above design, the flip cover 112 has a higher stability when in the locked state, thereby effectively reducing the possibility of accidental unlocking of the flip cover 112 during the use of the connection structure.

[0070] like Figure 5 As shown, further, an annular partition 1115 is provided on the base 111, and the annular partition 1115 is used to separate the open cavity 1113 into a first cavity 11131 and a second cavity 11132. The second cavity 11132 is arranged around the first cavity 11131, and the first cavity 11131 is used to place the position sensor 200. The limit member 1114 is arranged on the side of the annular partition 1115 facing the second cavity 11132.

[0071] In this embodiment, the first cavity 11131 is separated by the annular partition 1115, which facilitates the fixing of the position sensor 200. At the same time, the arrangement of the annular partition 1115 and the second cavity 11132 facilitates the arrangement of the stopper 1114.

[0072] Of course, for the above-mentioned embodiment of the limiting member 1114, the limiting member 1114 can also be a limiting groove opened on the annular partition 1115. Through the mutual engagement of the limiting groove and the elastic clip 1122, the flip cover 112 can also have a higher stability when in the locked state. No specific restrictions are made on the structure of the limiting member 1114 here.

[0073] In another embodiment, the fixing part 110 includes a limiting plate and a screw, and the screw is passed through the position sensor 200 to fix it on the limiting plate, which can also achieve the limitation of the position sensor 200, and the position sensor 200 can be disassembled relative to the connector 100 by screwing the screw. No specific limitation is made to the structure of the fixing part 110 herein.

[0074] like Figure 1 and Figure 2 As shown, in a second aspect, an embodiment of the present application provides a therapeutic device 1000, including an ablation gun 300, a position sensor 200, a cystoscope 400 (the structure of the cystoscope 400 is not shown in the drawings), and a connector 100 in any of the above embodiments.
