Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a conductive joint. Background Art

[0002] Endoscopic mucosal resection or dissection is a minimally invasive surgery performed under endoscopy, mainly used to treat benign tumors and early malignant tumors in the gastrointestinal tract. This surgery usually requires the use of a high-frequency electric knife device to cut and coagulate the diseased tissue through the high-frequency current generated by the electrode, thereby achieving the purpose of removing the lesion.

[0003] In the existing technology, there are two main solutions. One is to use a monopolar medical device with a negative electrode plate to remove the diseased tissue. The negative electrode plate is attached to the patient and cooperates with a high-frequency electrosurgical device to form a current loop, thereby achieving cutting and coagulation of the diseased tissue. The other is to use a bipolar medical device to remove the diseased tissue.

[0004] Active medical devices require conductive connectors during use. The conductive connectors in the prior art have a complex structure and high cost. The conductive connectors need to be moved during use, which can easily cause the conductive connectors to separate from the medical devices, thereby affecting the quality of life for patients.

[0005] The prior art includes an invention patent named "plug", the publication number of which is JP2023064779A. The scheme of this invention is: a plug connected to a cable having a core wire and a conductor different from the core wire, the plug having: a first electrode having a pin-shaped terminal electrically connected to the core wire, a cylindrical second electrode insulated from the first electrode via an insulating component, a receiving portion connected to the second electrode and for the cable to be inserted, and a cylindrical cable conversion tube for the cable to be inserted and capable of being loaded and unloaded according to the cable diameter, and the cable conversion tube covers the side of the pin-shaped terminal through the cable in the installed state. However, this invention is relatively complex and the replacement cost is high if there is a problem.

[0006] Prior art includes an invention patent entitled "Connection plug for electromedical electrodes, mating plug, electromedical electrodes and electromedical connectors", the publication number of which is DE102021105988A1. This invention relates to improvements in the technical field of electromedical connectors, and proposes a connection plug for electromedical electrodes, which has at least one contact electrode, and the contact electrode is coated with a non-conductive protective layer that can be opened at least partially. However, this invention cannot achieve a good mating effect during movement. Summary of the invention

[0007] The purpose of the utility model is to provide a conductive joint with high self-protection capability, high cost compression, multiple usage scenarios, modular design and good matching effect.

[0008] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0009] The conductive connector comprises a conductive substrate, wherein the conductive substrate is embedded with at least one conductive plug-in sheet, and the output end of the conductive plug-in sheet is connected with a plug pin.

[0010] The length direction of the conductive plug is the same as that of the conductive substrate, and the conductive plug is evenly arranged in the conductive substrate. When there are two or more conductive plugs, the conductive plug is evenly arranged in the circumferential direction. A plug pin is provided at the end of the conductive plug to output the current inputted at the input end of the conductive plug through the plug pin, that is, the conductive connector outputs the current through the plug pin, that is, the receiving device needs to be provided with a receiving device corresponding to the conductive substrate and the plug pin to receive the current.

[0011] It should be noted that the conductive connector is mainly used for active medical devices, and the conductive plug mainly uses one or two conductive plugs to power the active medical devices. More specifically, a monopolar medical device uses a single conductive plug to be set in a conductive matrix, and a bipolar medical device uses two conductive plugs to be set in a conductive matrix. At this time, the direct current, low-frequency alternating current or high-frequency alternating current inputted at the input end of the conductive plug is outputted to the medical device through the pin.

[0012] It should be noted that the conductive substrate is made of insulating material.

[0013] According to an embodiment of the present invention, a notch is formed at the output end of the conductive plug, and the plug pin is arranged corresponding to the notch.

[0014] Through the above design, the corresponding arrangement of the pin and the notch enables the pin to cooperate with the conductive plug more flexibly. It should be noted that the arrangement of the notch achieves a contact connection between the pin and the conductive plug.

[0015] Furthermore, the pins can be replaced, so that the conductive connector can be modularly designed, and the pins can be replaced or produced according to the sizes of different receiving devices, thereby saving costs and improving the ease of replacement.

[0016] Furthermore, the slot is provided with a buffer section. It should be noted that the buffer section can reduce the possibility of damage and bending of the plug pin during the process of cooperating with the receiving device, that is, when the plug pin is subjected to a large impact force along the length direction, the buffer section can absorb the impact and control the position of the plug pin at the same time, so that the length of the plug pin extending out of the conductive substrate is controllable and limited, that is, when the plug pin is compressed and retracted into the buffer section, there will be a force to return to the original position to realize the return of the length of the plug pin extending out of the conductive substrate. It should be noted that the force here includes but is not limited to elastic force or pressure.

[0017] Furthermore, the pin is made of conductive material. More specifically, the pin is made of metal conductive material. Since the device will inevitably separate and combine the pin and the conductive substrate with the corresponding receiving device during use, the material selection of the pin will affect the service life of the pin and the overall device during this process. The use of metal material can increase the service life of the pin and reduce the possibility of the pin bending or breaking.

[0018] According to an embodiment of the utility model, the pin portion is exposed outside the conductive substrate.

[0019] It should be noted that the pin is used to transfer the current received by the conductive plug to the receiving device, and the pin portion is exposed to the outside to achieve contact with the receiving device.

[0020] According to an embodiment of the present invention, the conductive insert is partially exposed outside the conductive substrate.

[0021] The conductive plug needs to be connected to an external power source, and the exposed portion of the conductive plug is used to achieve the connection with the external power source.

[0022] According to an embodiment of the present invention, the input end and the output end of the conductive plug are arranged in parallel and staggered, and a connecting section is obliquely arranged between the input end and the output end of the conductive plug.

[0023] The length, angle, thickness and width of the connecting section of the conductive plug can be adjusted according to different needs. The setting of the connecting section of the conductive plug can improve the ability of the slot to absorb impact force, and the connecting section can achieve the ability to adapt to external cold and heat, preventing the conductive plug from being disconnected from the pin or the input device at its input end after the external temperature changes. In addition, the setting of the connecting section can achieve the accuracy of the conductive plug lower than that of the straight conductive plug, which is conducive to the control of production and replacement costs.

[0024] Furthermore, when used on a bipolar ferrule, two symmetrically arranged conductive plugs are provided in the conductive matrix, and the connecting sections of the two conductive plugs are arranged to be tilted back to back, that is, the input end spacing of the two conductive plugs is smaller than the output end spacing.

[0025] According to an embodiment of the utility model, the conductive substrate has an expansion portion, and at least one boss is provided on the side of the expansion portion.

[0026] The expansion portion can make it easier to distinguish the input end and the output end of the conductive substrate, and the expansion portion can also form protection for the conductive insert in the conductive substrate.

[0027] Through the above design, the boss arranged on the side of the expansion part is used to achieve a snap-fit ​​fit with the receiving device. It should be noted that a groove corresponding to the boss needs to be provided on the inner side wall of the receiving device. The expansion part and the receiving device can be firmly fitted together through the cooperation of the groove and the boss to prevent the conductive connector from falling off during use or the pin from having poor contact with the receiving device.

[0028] According to an embodiment of the utility model, an input portion is extended from one end of the expansion portion, an exposed section is embedded in a side surface of the input portion, and the exposed section is arranged corresponding to one end of the conductive plug.

[0029] The input part corresponds to one end of the conductive plug. It should be noted that the exposed section of the input part can realize the connection between the external current and the conductive plug, thereby realizing the power supply of the conductive plug to the cut wire. The exposed part of the conductive plug is set corresponding to the exposed section. Moreover, the probability of disconnection of the conductive plug can be reduced by the exposed section.

[0030] According to an embodiment of the utility model, a cavity for accommodating the conductive plug is provided in the expansion portion.

[0031] By providing a chamber for accommodating the conductive plug in the expansion part, the expansion part can protect the output end and the connecting section of the conductive plug, and can prevent the conductive plug from breaking through the conductive substrate during the process of inputting direct current, low-frequency alternating current or high-frequency alternating current.

[0032] According to an embodiment of the utility model, at least one clamping groove is provided on the expansion portion facing the insertion pin.

[0033] The snap-in groove is used to improve the connection effect between the pin and the receiving device, and can improve the docking tightness between the pin and the receiving device, which is beneficial to reduce the misalignment of the pin and the receiving device during the use of the overall device, and is beneficial to the convenience of operation for the operator.

[0037] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods and drawings:

[0038] Embodiment 1:

[0039] like Figure 1 and Figure 2 The conductive connector comprises a conductive substrate 1 , in which at least one conductive plug 2 is embedded, and an output end 23 of the conductive plug 2 is connected to a plug pin 3 .

[0040] The length direction of the conductive plug 2 is the same as that of the conductive substrate 1, and the conductive plug 2 is evenly arranged in the conductive substrate 1. When there are two or more conductive plugs 2, the conductive plugs 2 are evenly arranged in the circumferential direction. A pin 3 is provided at the end of the conductive plug 2 to output the current input from the input end 22 of the conductive plug 2 through the pin 3, that is, the conductive connector outputs the current through the pin 3, that is, the receiving device needs to be provided with a receiving device corresponding to the conductive substrate 1 and the pin 3 to receive the current.

[0041] It should be noted that the conductive connector is mainly used for active medical devices, and the conductive plug 2 mainly uses one or two conductive plugs 2 to power the ferrule. More specifically, the monopolar ferrule uses a single conductive plug 2 to be set in the conductive substrate 1, and the bipolar ferrule uses two conductive plugs 2 to be set in the conductive substrate 1. At this time, the direct current, low-frequency alternating current or high-frequency alternating current inputted from the input end 22 of the conductive plug 2 is outputted to the medical device through the pin 3.

[0042] It should be noted that the conductive substrate 1 is made of insulating material.

[0043] The output end 23 of the conductive plug 2 is provided with a slot 21 , and the plug pin 3 is arranged corresponding to the slot 21 .

[0044] Through the above design, the corresponding arrangement of the pin 3 and the notch 21 enables the pin 3 to cooperate with the conductive plug 2 more flexibly. It should be noted that the arrangement of the notch 21 achieves a contact connection between the pin 3 and the conductive plug 2.

[0045] Furthermore, the pin 3 can be replaced, so that the conductive joint can be modularly designed, and the pin 3 can be replaced or produced according to the sizes of different receiving devices, thereby saving costs and improving the ease of replacement.

[0046] Furthermore, the slot 21 is provided with a buffer section. It should be noted that the buffer section can reduce the possibility of damage and bending of the plug pin 3 in the process of cooperating with the receiving device, that is, when the plug pin 3 is subjected to a large impact force along the length direction, the buffer section can absorb the impact and control the position of the plug pin 3, so that the length of the plug pin 3 extending out of the conductive substrate 1 is controllable and limited, that is, when the plug pin 3 is compressed and retracted into the buffer section, there will be a force to return to the original position to realize the return of the length of the plug pin 3 extending out of the conductive substrate 1. It should be noted that the force here includes but is not limited to elastic force or pressure.

[0047] Furthermore, the pin 3 is made of conductive material. More specifically, the pin 3 is made of metal conductive material. Since the device will inevitably separate and combine the pin 3 and the conductive substrate 1 with the corresponding receiving device during use, the material selection of the pin 3 will affect the service life of the pin 3 and the entire device during this process. The use of metal material can increase the service life of the pin 3 and reduce the possibility of the pin 3 being bent or broken.

[0048] The pins 3 are partially exposed outside the conductive substrate 1 .

[0049] It should be noted that the pin 3 is used to transfer the current received by the conductive plug 2 to the cutting wire or receiving device, and a portion of the pin 3 is exposed to the outside to achieve contact with the receiving device.

[0050] The conductive insert 2 is partially exposed outside the conductive substrate 1 .

[0051] The conductive plug 2 needs to be connected to an external power source, and the exposed portion of the conductive plug 2 is used to achieve the connection with the external power source.

[0052] The input end 22 and the output end 23 of the conductive plug 2 are arranged in parallel and staggered, and a connecting section 24 is arranged obliquely between the input end 22 and the output end 23 of the conductive plug 2 .

[0053] The length, angle, thickness and width of the connecting section 24 of the conductive plug 2 can be adjusted according to different needs. The setting of the connecting section 24 of the conductive plug 2 can improve the ability of the slot 21 to absorb impact force, and the connecting section 24 can achieve the ability to adapt to external cold and heat, preventing the conductive plug 2 from being disconnected from the pin 3 or the input device of its input end 22 after the external temperature changes. In addition, the setting of the connecting section 24 can achieve that the accuracy of the conductive plug 2 can be lower than that of a straight conductive plug 2, which is conducive to the control of production and replacement costs.

[0054] Furthermore, when used on a bipolar medical device, two symmetrically arranged conductive plugs 2 are provided in the conductive substrate 1, and the connecting sections 24 of the two conductive plugs 2 are arranged to be tilted back to back, that is, the spacing between the input ends 22 of the two conductive plugs 2 is smaller than the spacing between the output ends 23.

[0055] The conductive substrate 1 has a bulging portion 11 , and at least one boss 12 is disposed on the side of the bulging portion 11 .

[0056] The expansion portion 11 can make it easier to distinguish the input end 22 and the output end 23 of the conductive substrate 1 , and the expansion portion 11 can also protect the conductive insert 2 in the conductive substrate 1 .

[0057] Through the above design, the boss 12 arranged on the side of the expansion part 11 is used to achieve a snap-fit ​​fit with the receiving device. It should be noted that a groove corresponding to the boss 12 needs to be provided on the inner side wall of the receiving device. The groove and the boss 12 cooperate to achieve a stable fit between the expansion part 11 and the receiving device, thereby preventing the conductive connector from falling off during use or the pin 3 from having poor contact with the receiving device.

[0058] An input portion 13 is extended from one end of the expansion portion 11 , and an exposed section 14 is embedded in a side surface of the input portion 13 . The exposed section 14 is arranged corresponding to one end of the conductive plug 2 .

[0059] The input portion 13 corresponds to one end of the conductive plug 2. It should be noted that the exposed section 14 of the input portion 13 can realize the connection between the external current and the conductive plug 2, thereby realizing the power supply of the conductive plug 2 to the receiving device. The exposed part of the conductive plug 2 is arranged corresponding to the exposed section 14. Moreover, the exposed section 14 can reduce the probability of disconnection of the conductive plug 2.

[0060] The expansion portion 11 has a chamber therein for accommodating the conductive plug 2 .

[0061] By providing a chamber for accommodating the conductive plug 2 in the expansion portion 11, the expansion portion 11 can protect the output end 23 and the connecting section 24 of the conductive plug 2, and can prevent the conductive plug 2 from breaking through the conductive substrate 1 during the process of inputting direct current, low-frequency alternating current or high-frequency alternating current into the conductive plug 2.

[0062] The expansion portion 11 is provided with at least one engaging groove 15 on the side facing the insertion pin 3 .

[0063] The snap-in groove 15 is used to improve the connection effect between the pin 3 and the receiving device, and can improve the docking tightness between the pin 3 and the receiving device, which is beneficial to reduce the misalignment of the pin 3 and the receiving device during the use of the overall device, and is beneficial to the convenience of operation for the operator.
