Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an energy surgical active cooling device and an energy surgical active cooling system. Background Technology
[0002] Energy-based medical devices are primarily used in electrosurgical procedures for tissue cutting and the closure and sealing of blood vessels or tissues. The thermal diffusion damage to adjacent or surrounding tissues caused by the electrodes at the closure site is a critical issue that urgently needs to be addressed in current clinical surgical procedures.
[0003] Existing energy surgical electrode assemblies typically utilize the principle of thermoelectric cooling plates, incorporating thermoelectric cooling plates in the clamping area to control the direction of heat transfer and achieve cooling. However, since the basic principle of thermoelectric cooling plates is an energy conversion technology that utilizes the Peltier effect of semiconductor materials to achieve cooling or heating, when connected to a DC power supply, the temperature at one end of the thermoelectric cooling device decreases while the temperature at the other end simultaneously increases. Because this principle generates new heat on the other side while cooling one side, a separate heat dissipation mechanism is needed to conduct this heat simultaneously. Therefore, existing energy surgical electrode assemblies are not only structurally complex and difficult to manufacture, but also have low clamping head cooling efficiency. Summary of the Invention
[0004] In view of this, the present invention provides an active cooling device and an active cooling system for energy surgery to solve the problems that existing energy surgical electrode assemblies are not only complex in structure and difficult to manufacture, but also have low cooling efficiency of the forceps tip.
[0005] In a first aspect, the present invention provides an energy-assisted surgical active cooling device, comprising:
[0006] First clamping body;
[0007] The second clamping body is connected to the first clamping body, and the distal end of the second clamping body is adapted to abut against the distal end of the first clamping body;
[0008] A cooling structure is disposed on at least one of the first clamping body and the second clamping body; the cooling structure is hollow inside and forms a receiving cavity, the receiving cavity being adapted to contain a cooling medium.
[0009] The receiving cavity is connected to an external cold source, and the receiving cavity is adapted to allow cooling medium to circulate between the receiving cavity and the external cold source so as to conduct heat from the first clamp and / or the second clamp from the distal tip to the external cold source.
[0010] Beneficial effects: The energy surgical active cooling device provided by the present invention provides a cooling structure on at least one of the first and second clamping bodies. The cooling structure is hollow and forms a receiving cavity. The receiving cavity contains a cooling medium, thereby cooling down the heat-generating parts of the first and / or second clamping bodies. The receiving cavity is connected to an external cold source, thereby continuously transferring the heat of the heat-generating parts to the external cold source through the circulation of the cooling medium. This not only eliminates the heat risk of the heat-generating surface and avoids setting up another heat dissipation structure in the clamping body for simultaneous heat conduction, thus improving the heat dissipation and cooling efficiency of the clamping body, but also simplifies the heat dissipation structure of the clamping body and reduces the manufacturing difficulty of the energy surgical active cooling device.
[0011] In one alternative embodiment, the first clamping body includes a clamping body and clamping tips; the cooling structure includes a cooling block body and a first sealing head;
[0012] The cooling block body is independently disposed at the tip of the first clamping body. The cooling block body is disposed on the side of the first clamping body away from the second clamping body along the first direction. The cooling block body and the side of the first clamping body away from the second clamping body along the first direction are attached to each other.
[0013] A first receiving groove is formed on the cooling block body; a first sealing head is adapted to seal the first receiving groove to close the first receiving groove and form a receiving cavity.
[0014] Beneficial effects: The cooling block body and the first clamping body are fitted together along the side away from the second clamping body in the first direction to ensure the heat transfer area between the cooling block body and the first clamping body, improve the heat transfer efficiency between the cooling block body and the first clamping body, and facilitate the cooling block body to remove the heat on the clamping body in time, which is conducive to improving the cooling efficiency and avoiding redundant heat damage to surrounding blood vessels or nerves; the first receiving groove is sealed by the first sealing head to form a receiving cavity, thereby reducing the processing difficulty of the first receiving groove and the assembly difficulty of the cooling structure.
[0015] In one optional embodiment, the cooling structure further includes a first tube and a second tube, both of which are disposed on the side of the first clamping body away from the second clamping body along a first direction.
[0016] The distal end of the first tube is connected to the receiving cavity, the proximal end of the first tube is adapted to be connected to an external cold source, and the first tube is adapted to continuously introduce the cooling medium from the external cold source into the receiving cavity.
[0017] The distal end of the second tube is connected to the receiving cavity, and the proximal end of the second tube is adapted to be connected to an external cold source. The second tube is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity to the external cold source.
[0018] Beneficial effects: By setting up the first tube and the second tube, a circulating cooling circuit is formed between the cooling block body and the external cold source. Not only will there be no excess heat generation, avoiding redundant heat damage to surrounding blood vessels or nerves, but the cooling efficiency of the cooling structure for the first clamping body can also be greatly improved.
[0019] In one optional embodiment, the first clamping body includes a clamping body and a clamping tip; the cooling structure includes a third tube, which is disposed on the side of the first clamping body away from the second clamping body along a first direction; the third tube has a U-shaped structure, and the third tube is bent and deflected at the distal end of the clamping tip of the first clamping body.
[0020] The third tube is a one-piece molded structure. The input end of the third tube is connected to the cooling medium output port of the external cold source, and the output end of the third tube is connected to the cooling medium return port of the external cold source. The cooling medium is suitable for circulating inside the third tube to cool the first clamping body.
[0021] Beneficial effects: During operation, the third tube can promptly remove heat from both sides of the first clamping body in the first direction without generating excess heat. This creates a low-temperature safety zone around the entire circumference of the first clamping body, effectively preventing damage to surrounding blood vessels or nerves and greatly improving the safety of electrosurgical procedures. On the other hand, the third tube is a one-piece molded "U"-shaped structure, eliminating the need for additional heat dissipation and sealing components, greatly simplifying the cooling structure and reducing manufacturing difficulty.
[0022] In one alternative embodiment, the first clamping body includes a clamping body and a clamping tip; the cooling structure includes a fourth tube and a circulating cooling assembly, the fourth tube and the circulating cooling assembly being disposed on the side of the first clamping body away from the second clamping body along a first direction;
[0023] The fourth tube is located at one end of the first clamping body along the axial direction near the tip of the clamp. The fourth tube is adapted to contain a cooling medium to cool the first clamping body.
[0024] The circulating cooling component is located at one end of the first clamping body along the axial direction near the clamp body. The far end of the circulating cooling component is connected to the fourth tube body, and the near end of the circulating cooling component is adapted to be connected to an external cold source. The circulating cooling component is adapted to continuously cool the cooling medium inside the fourth tube body.
[0025] Beneficial effects: During operation, the circulating cooling component forms a circulation loop with the external cold source. Simultaneously, the circulating cooling component and the fourth tube transfer heat to the external cold source, thereby cooling the first clamping body. The fourth tube is located at the end of the first clamping body near the tip along the axial direction. This not only cools the first clamping body but also reduces the thickness of the tip along the first direction and the width along the second direction, thus reducing the size of the tip. While ensuring basic clamping and cutting functions and cooling efficiency, the first clamping body can be miniaturized, preventing the clamp tip from touching nerves or blood vessels in complex and confined surgical spaces, avoiding the risk of heat damage, and greatly improving the safety of electrosurgical procedures.
[0026] In one alternative embodiment, the circulating cooling assembly includes a connecting block, a fifth tube, and a sixth tube, the connecting block being adapted to simultaneously connect the fourth, fifth, and sixth tubes.
[0027] Both the fifth and sixth tubes are located near the first clamping body; the distal end of the fifth tube is connected to the connecting block, and the proximal end of the fifth tube is adapted to be connected to the cooling medium outlet of the external cold source; the distal end of the sixth tube is connected to the connecting block, and the proximal end of the sixth tube is adapted to be connected to the cooling medium return port of the external cold source.
[0028] Beneficial effects: By setting up a connecting block to simultaneously connect the fourth, fifth, and sixth tubes, heat within the fourth tube can be conducted to the connecting block. Through continuous cooling via the fifth and sixth tubes, the heat within the fourth tube is transferred to an external cold source. This allows the fourth tube to promptly remove heat from the first clamping body without generating excess heat, effectively preventing damage to surrounding blood vessels or nerves and improving the safety of electrosurgical procedures. Simultaneously, it allows for a more miniaturized first clamping body, preventing the clamp tip from touching nerves or blood vessels in complex and confined surgical spaces, avoiding the risk of heat injury, and greatly improving the safety of electrosurgical procedures.
[0029] In one alternative embodiment, the first clamping body includes a clamping body and clamping tips; the cooling structure includes a first plate and a second sealing head;
[0030] The first plate is fixedly disposed on the side of the first clamping body that is close to the second clamping body along the first direction, and the first plate is adapted to abut against the second clamping body; a cooling part is formed on the side of the first plate that is away from the second clamping body along the first direction, and the cooling part is disposed at one end of the first plate that is close to the tip of the clamp along the axial direction, and the cooling part and the first plate are integrally formed.
[0031] A second receiving groove is formed on the cooling section; a second sealing head is adapted to seal the second receiving groove to close the second receiving groove and form a receiving cavity.
[0032] Beneficial effects: It allows the cooling part of the first clamping body to be disassembled into a single component that is directly connected to the water channel, avoiding the need for a separate cooling block, thereby further improving the efficiency of cooling and heat dissipation.
[0033] In one optional embodiment, the cooling structure further includes a seventh tube and an eighth tube, both of which are disposed on the side of the first clamping body away from the second clamping body along a first direction.
[0034] The distal end of the seventh tube is connected to the receiving cavity, and the proximal end of the seventh tube is adapted to be connected to an external cold source. The seventh tube is adapted to continuously introduce the cooling medium from the external cold source into the receiving cavity.
[0035] The distal end of the eighth tube is connected to the receiving cavity, and the proximal end of the eighth tube is adapted to be connected to an external cold source. The eighth tube is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity to the external cold source.
[0036] Beneficial effects: By setting the seventh and eighth tubes, the cooling section of the first plate is connected to the external cold source to form a circulating cooling circuit. This not only prevents the generation of excess heat and avoids damage to surrounding blood vessels or nerves from redundant heat, but also greatly improves the cooling efficiency of the cooling structure for the first plate.
[0037] In one optional embodiment, the first clamping body includes a clamping body and a clamping tip; the cooling structure includes a housing portion disposed at one end of the first clamping body along the axial direction near the clamping tip, and the housing portion is integrally formed with the first clamping body.
[0038] The housing portion has a third receiving groove formed on the side of the first clamping body near the second clamping body along the first direction; the cooling structure also includes a second plate, which is fixedly disposed on the side of the first clamping body near the second clamping body along the first direction. The second plate is adapted to cover the third receiving groove to close the third receiving groove and form a receiving cavity.
[0039] Beneficial effects: The larger volume of the accommodating cavity allows for a greater amount of cooling medium, which greatly increases the cooling area of the first clamping body and improves the cooling efficiency of the first clamping body.
[0040] In one optional embodiment, the proximal end of the first clamping body is provided with a first through hole and a second through hole, the first through hole and the second through hole extending axially toward the position near the clamp tip and both communicating with the third receiving groove.
[0041] The cooling structure also includes a ninth tube and a tenth tube, both of which are located at the end of the first clamping body that is axially away from the tip of the clamp.
[0042] The distal end of the ninth tube is connected to the first through hole, the proximal end of the ninth tube is adapted to be connected to an external cold source, and the ninth tube is adapted to continuously introduce the cooling medium from the external cold source into the receiving cavity through the first through hole.
[0043] The distal end of the tenth tube is connected to the second through hole, the proximal end of the tenth tube is adapted to be connected to an external cold source, and the tenth tube is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity to the external cold source through the second through hole.
[0044] Beneficial effects: By setting the first through hole and the ninth tube, as well as the second through hole and the tenth tube, the cavity formed by the shell and the second plate is connected to the external cold source to form a circulating cooling circuit. Not only will there be no excess heat generation, avoiding redundant heat damage to surrounding blood vessels or nerves, but the cooling efficiency of the cooling structure for the first clamping body can also be greatly improved.
[0045] In one alternative embodiment, the first clamping body includes a tweezer body and a tweezer tip; the tip of the first clamping body is hollow inside and forms a receiving cavity;
[0046] The cooling structure includes an eleventh tube and a twelfth tube, which are respectively disposed on the second side of the tweezers body of the first clamping body and extend axially to the tip of the tweezers of the first clamping body.
[0047] The distal end of the eleventh tube is connected to the receiving cavity, and the proximal end of the eleventh tube is connected to the cooling medium outlet of the external cold source. The eleventh tube is adapted to continuously introduce the cooling medium from the external cold source into the receiving cavity. The distal end of the twelfth tube is connected to the receiving cavity, and the proximal end of the twelfth tube is connected to the cooling medium return port of the external cold source. The twelfth tube is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity to the external cold source.
[0048] Beneficial effects: By setting up the eleventh and twelfth tubes, a circulating cooling circuit is formed between the receiving cavity at the tip of the first clamping body and the external cold source. During operation, the cooling structure and its internal cooling medium can promptly remove heat from the tip of the clamping body without generating excess heat. This creates a low-temperature safety zone throughout the entire circumferential area of the first and / or second clamping bodies. This allows surgeons or physicians to selectively use the first clamping body as a fulcrum away from nerves or blood vessels during actual clinical surgery, effectively avoiding redundant heat damage to surrounding blood vessels or nerves caused by both clamping bodies heating up during electrocoagulation or electroresection, greatly improving the safety of electrosurgical procedures. Simultaneously, it eliminates the heat risk from the heating surface, avoiding the need for a separate heat dissipation structure within the clamping body for simultaneous heat conduction. This not only improves the heat dissipation and cooling efficiency of the clamping body and enhances the safety during clinical surgery, but also simplifies the heat dissipation structure of the clamping body and reduces the technological difficulty of the active cooling device for energy surgery.
[0049] In one optional embodiment, the second clamping body includes a tweezer body and a tweezer tip; the tip of the second clamping body is hollow inside and forms a receiving cavity;
[0050] The cooling structure includes a thirteenth tube and a fourteenth tube, which are respectively disposed on both sides of the tweezers body of the second clamping body in the second direction and extend axially to the tip of the tweezers of the second clamping body.
[0051] The distal end of the thirteenth tube is connected to the receiving cavity, and the proximal end of the thirteenth tube is connected to the cooling medium outlet of the external cold source. The thirteenth tube is adapted to continuously introduce the cooling medium from the external cold source into the receiving cavity. The distal end of the fourteenth tube is connected to the receiving cavity, and the proximal end of the fourteenth tube is connected to the cooling medium return port of the external cold source. The fourteenth tube is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity to the external cold source.
[0052] Beneficial effects: During operation, the cooling structure and cooling medium of the "double-sided tweezers cooling structure" can remove the heat from the tips of the two clamping bodies in a timely manner without generating excess heat. This creates a low-temperature safety zone in the entire circumferential area of the first and second clamping bodies, thereby further improving the efficiency of cooling and heat dissipation.
[0053] In one alternative embodiment, the energy surgical active cooling device further includes a connecting block disposed between the first clamping body and the second clamping body, the connecting block being adapted to connect the proximal end of the first clamping body to the proximal end of the second clamping body.
[0054] Beneficial effects: In an energy surgical active cooling device for monopolar and bipolar metal electrodes used in laparoscopy, the connecting block is suitable for rotatably connecting the first clamping body and the second clamping body to achieve basic clamp opening and closing functions; in an energy surgical active cooling device for high-frequency bipolar forceps, the connecting block is suitable for fixing the first clamping body and the second clamping body to achieve basic forceps tip pinching functions.
[0055] Secondly, the present invention also provides an energy surgical active cooling system, comprising: an external cold source, and an energy surgical active cooling device as described above, wherein the external cold source is adapted to supply a cooling medium to the cooling structure.
[0056] Beneficial effects: The second aspect of the energy surgical active cooling system includes the first aspect of the energy surgical active cooling device, therefore, the second aspect of the energy surgical active cooling system includes all the beneficial effects of the first aspect of the energy surgical active cooling device.
[0057] In one alternative implementation, the energy surgical active cooling system further includes a pumping device adapted to power the circulation of cooling medium between the cooling structure and an external cold source.
[0058] Beneficial effects: The active cooling system for energy surgery uses a pumping device to provide power for the circulation of cooling medium between the cooling structure and the external cold source. During operation, the circulation rate and flow rate of the cooling medium can be adjusted by the pumping device, thereby adjusting the cooling effect of the cooling structure on the clamping body.
[0059] In one alternative implementation, the energy surgical active cooling system further includes a refrigeration device adapted to cool the cooling medium.
[0060] Beneficial effects: The active cooling system for energy surgery uses a refrigeration device to cool the cooling medium, thereby increasing the temperature difference between the heating part of the clamp and the cooling medium, and improving the cooling efficiency of the cooling structure for the clamp.

[0089] In related technologies, energy surgical electrode assemblies utilize the principle of thermoelectric cooling plates, designing thermoelectric cooling plates in the clamping head area. By controlling the direction of heat transfer, cooling and heat dissipation are achieved in the clamping direction of the clamping head. However, on the one hand, since the basic principle of thermoelectric cooling plates is an energy conversion technology that uses the Peltier effect of semiconductor materials to achieve cooling or heating, when connected to a DC power supply, the temperature of one end of the thermoelectric cooling device decreases while the temperature of the other end increases simultaneously. This not only results in a low coefficient of performance, but also, because this principle generates new heat on the other side while cooling one side, this heat requires a separate heat dissipation mechanism to conduct heat simultaneously. This not only makes the structure complex and difficult to manufacture, but also results in low clamping head cooling efficiency. On the other hand, existing energy surgical electrode assemblies are only suitable for clinical surgery after the fascia around blood vessels has been freed. While applicable to certain scenarios, the surgical space in these scenarios is relatively large, allowing for heat dissipation from the heated area on the back of the electrothermal cooling system through natural convection. However, the inherent risk of heat from the heated surface remains. More importantly, in actual clinical surgeries such as tumor resection and fascia dissection, the surgeon operates in a very confined space, with surrounding blood vessels and nerves constantly in close proximity to the instrument heads. When both bipolar forceps heads are heated, if either forceps head touches a nerve or blood vessel due to unavoidable factors such as fatigue, it can cause irreversible trauma and poses a significant safety risk.
[0090] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0091] The following is combined Figures 1 to 17 The following describes embodiments of the present invention.
[0092] According to an embodiment of the present invention, in one aspect, an energy surgical active cooling device is provided, comprising:
[0093] First clamping body 101;
[0094] The second clamping body 102 is connected to the first clamping body 101, and the distal end of the second clamping body 102 is adapted to abut against the distal end of the first clamping body 101.
[0095] A cooling structure 103 is disposed on at least one of the first clamping body 101 and the second clamping body 102; the cooling structure 103 is hollow inside and forms a receiving cavity 104, which is adapted to contain a cooling medium.
[0096] The receiving cavity 104 is connected to the external cold source 200. The receiving cavity 104 is adapted to circulate a cooling medium between itself and the external cold source 200 so as to conduct heat from the first clamping body 101 and / or the second clamping body 102 from the distal tip to the external cold source 200.
[0097] It should be noted that, for better understanding, the terms "proximal (end / side)" and "distal (end / side)" are defined from the perspective of the physician (or other surgeon). Therefore, the term "proximal (end / side)" is used to refer to the side or end of the device closest to the external body wall and / or the surgeon, or the portion thereon, while the term "distal (end / side)" refers to the side or end of the structure in the direction opposite to the external body wall and / or the surgeon.
[0098] It should be noted that the "cooling medium" has thermal conductivity and can be a gaseous cooling medium, a liquid cooling medium, or a gas-liquid mixture cooling medium; the specific composition of the cooling medium can be configured according to actual clinical needs, and no specific limitations are made here.
[0099] It is worth noting that, compared with the heat dissipation method of electrode sealing components in related technologies, the energy surgical active cooling device provided by the present invention continuously cools the cooling medium in the receiving cavity 104 through the continuous cooling cycle between the cooling structure 103 and the external cold source 200, ensuring that the cooling medium is always in a good low-temperature cooling state. During operation, the cooling structure 103 and the cooling medium therein can not only remove heat from the opposite side of the first clamping body 101 and the second clamping body 102 in a timely manner, but also remove heat from the opposite side of the first clamping body 101 and the second clamping body 102 in a timely manner, without generating excess heat. This creates a low-temperature safety zone in the entire circumferential area of the first clamping body 101 and / or the second clamping body 102, allowing the surgeon or physician to selectively cool the first clamping body 101 and / or the second clamping body 102 during actual clinical surgery. The two clamping bodies 102, acting as fulcrums away from nerves or blood vessels, effectively prevent redundant heat generated during electrocoagulation or electrocautery from damaging surrounding blood vessels or nerves, thus greatly improving the safety of electrosurgical procedures. Compared with the heat dissipation structure of electrode sealing assemblies in related technologies, the energy surgical active cooling device provided by this invention, by setting a cooling structure 103, connects the receiving cavity 104 of the cooling structure 103 to an external cold source 200, and through continuous cooling circulation between the cooling structure 103 and the external cold source 200, eliminates the heat risk of the heating surface and avoids setting another set of heat dissipation structures in the clamping body for simultaneous heat conduction. This not only improves the heat dissipation and cooling efficiency of the clamping body and enhances the safety of clinical procedures, but also simplifies the heat dissipation structure of the clamping body and reduces the manufacturing difficulty of the energy surgical active cooling device.
[0100] The energy surgical active cooling device provided by the present invention provides a cooling structure 103 on at least one of the first clamping body 101 and the second clamping body 102. The cooling structure 103 is hollow and forms a receiving cavity 104. The receiving cavity 104 contains a cooling medium, thereby cooling down the heat-generating parts of the first clamping body 101 and / or the second clamping body 102. The receiving cavity 104 is connected to an external cold source 200, thereby continuously transferring the heat of the heat-generating parts to the external cold source 200 through the circulation of the cooling medium. This not only eliminates the heat risk of the heat-generating surface and avoids setting up another heat dissipation structure in the clamping body for simultaneous heat conduction, thus improving the heat dissipation and cooling efficiency of the clamping body, but also simplifies the heat dissipation structure of the clamping body and reduces the manufacturing difficulty of the energy surgical active cooling device.
[0101] It should be noted that the energy surgical active cooling device provided by the present invention is mainly used for active cooling of energy instruments in electrosurgical procedures during surgery. To better illustrate and understand the present invention, the following description will specifically use the energy surgical active cooling device applied to monopolar and bipolar metal electrodes under laparoscopy and the energy surgical active cooling device applied to high-frequency bipolar forceps as examples.
[0102] Please combine them together Figures 1-3 As shown, the following provides an example of a first energy surgical active cooling device for monopolar and bipolar metal electrodes under laparoscopy, wherein the cooling structure 103 mainly includes a cooling block body 11, a first sealing head 12, a first tube body 13 and a second tube body 14, thereby forming an "independent cooling block-independent dual tube cooling structure".
[0103] In some embodiments, see Figure 1 As shown, the first clamping body 101 includes a clamping body 106 and clamping tips 107; please refer to... Figure 2 As shown, the cooling structure 103 includes a cooling block body 11 and a first sealing head 12;
[0104] Please combine them together Figure 3 As shown, the cooling block body 11 is independently disposed at the tip of the clamping tip 107 of the first clamping body 101. The cooling block body 11 is fixedly disposed on the side of the first clamping body 101 away from the second clamping body 102 along the first direction. The cooling block body 11 and the side of the first clamping body 101 away from the second clamping body 102 along the first direction are fitted together to ensure the heat transfer area between the cooling block body 11 and the first clamping body 101, improve the heat transfer efficiency between the cooling block body 11 and the first clamping body 101, and facilitate the cooling block body 11 to remove the heat on the clamping body in time, which is beneficial to improving the cooling efficiency and avoiding redundant heat damage to surrounding blood vessels or nerves.
[0105] A first receiving groove 111 is formed on the cooling block body 11; the first sealing head 12 is adapted to seal the first receiving groove 111 to close the first receiving groove 111 to form a receiving cavity 104, thereby reducing the processing difficulty of the first receiving groove 111 and the assembly difficulty of the cooling structure 103.
[0106] Further, please see Figure 3 As shown, a countersunk platform (not shown in the figure) can be formed at the tip of the clamping tip 107 of the first clamping body 101. The countersunk platform is adapted to fit and be fixedly connected to one side of the cooling block body 11.
[0107] In some embodiments, see Figure 3 As shown, the cooling structure 103 also includes a first tube 13 and a second tube 14, both of which are independently disposed on the side of the first clamping body 101 away from the second clamping body 102 along the first direction.
[0108] Please combine them together Figure 2 As shown, the distal end of the first tube 13 is connected to the receiving cavity 104, and the proximal end of the first tube 13 is adapted to be connected to the external cold source 200. The first tube 13 is adapted to continuously introduce the cooling medium from the external cold source 200 into the receiving cavity 104.
[0109] The distal end of the second tube 14 is connected to the receiving cavity 104, and the proximal end of the second tube 14 is adapted to be connected to the external cold source 200. The second tube 14 is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity 104 to the external cold source 200.
[0110] In this embodiment, by setting the first tube 13 and the second tube 14, the cooling block body 11 and the external cold source 200 form a circulating cooling circuit. Not only will there be no excess heat generation, avoiding redundant heat damage to surrounding blood vessels or nerves, but the cooling efficiency of the cooling structure 103 on the first clamping body 101 can also be greatly improved.
[0111] Further, please see Figure 3 As shown, a limiting groove (not shown in the figure) can be formed on the side of the first clamping body 101 away from the second clamping body 102 along the first direction, so as to embed the first tube 13 and the second tube 14 into the limiting groove. This not only reduces the risk of damage to the first tube 13 and the second tube 14, but also helps to optimize the overall structure of the first clamping body 101, reduce the volume of the first clamping body 101, and facilitate the surgeon to perform more precise cutting or electrocoagulation operations during clinical surgery.
[0112] It is understandable that, in the specific implementation process, technicians may adjust the specific structure and size of the first clamping body 101 on the side away from the second clamping body 102 along the first direction according to the actual shape and size of the cooling block body 11, the first sealing head 12, the first tube body 13 and the second tube body 14, and are not limited to the situation described in this embodiment.
[0113] Please combine them together Figure 4 and Figure 5 As shown, the following provides an example of a second type of energy surgical active cooling device for monopolar and bipolar metal electrodes under laparoscopy. The cooling structure 103 mainly includes a third tube 21, which is an integrally formed "U"-shaped structure. The third tube 21 and the first clamping body 101 are independently set to form an "independent U-shaped cooling structure".
[0114] In some embodiments, please combine Figure 1 As shown, the first clamping body 101 includes a clamping body 106 and clamping tips 107; please refer to... Figure 5As shown, the cooling structure 103 includes a third tube 21, which is disposed on the side of the first clamping body 101 away from the second clamping body 102 along a first direction; please refer to the diagram. Figure 4 As shown, the third tube 21 has a U-shaped structure, and the third tube 21 is bent and deflected at the distal end of the clamp tip 107 of the first clamping body 101.
[0115] The third tube 21 is an integrally formed structure. The input end of the third tube 21 is connected to the cooling medium output port of the external cold source 200, and the output end of the third tube 21 is connected to the cooling medium return port of the external cold source 200. The cooling medium is suitable for circulating inside the third tube 21 to cool the first clamping body 101.
[0116] In this embodiment, the input end of the third tube 21 is connected to the cooling medium output port of the external cold source 200, and the output end of the third tube 21 is connected to the cooling medium return port of the external cold source 200, thereby forming a circulating cooling circuit with the external cold source 200. During operation, the third tube 21 can remove the heat from both sides of the first clamping body 101 in the first direction in a timely manner, without generating excess heat. This creates a low-temperature safety zone in the entire circumferential area of the first clamping body 101, effectively avoiding damage to surrounding blood vessels or nerves and greatly improving the safety of electrosurgical procedures. On the other hand, the third tube 21 is an integrally formed "U"-shaped structure, eliminating the need for additional heat dissipation and sealing components, greatly simplifying the cooling structure and reducing the manufacturing difficulty.
[0117] Further, please see Figure 5 As shown, a U-shaped limiting groove (not shown in the figure) can be formed at the edge of the first clamping body 101 to embed the third tube 21 into the limiting groove. This not only reduces the risk of damage to the third tube 21, but also helps to optimize the overall structure of the first clamping body 101, reduce the volume of the first clamping body 101, and facilitate the surgeon to perform more precise cutting or electrocoagulation operations during clinical surgery.
[0118] It is understandable that, in the specific implementation process, technicians may adjust the specific structure and size of the limiting groove on the first clamping body 101 according to the actual shape and size of the third tube 21, and are not limited to the situation described in this embodiment.
[0119] Please combine them together Figure 6 and Figure 7As shown, the following provides an exemplary third type of energy surgical active cooling device for monopolar and bipolar metal electrodes under laparoscopy. The cooling structure 103 mainly includes a fourth tube 31 and a circulating cooling component 32. The fourth tube 31 and the circulating cooling component 32 are independently set from the first clamping body 101. The circulating cooling component 32 mainly includes a connecting block 321, a fifth tube 322 and a sixth tube 323, thereby forming an "independent three-way block-independent three-tube cooling structure".
[0120] In some embodiments, please combine Figure 1 As shown, the first clamping body 101 includes a clamping body 106 and clamping tips 107; please refer to... Figure 6 As shown, the cooling structure 103 includes a fourth tube 31 and a circulating cooling assembly 32, which are disposed on the side of the first clamping body 101 away from the second clamping body 102 along a first direction.
[0121] The fourth tube 31 is disposed at one end of the first clamping body 101 along the axial direction near the clamp tip 107. The fourth tube 31 is adapted to contain a cooling medium to cool the first clamping body 101.
[0122] The circulating cooling component 32 is located at one end of the first clamping body 101 along the axial direction near the clamp body 106. The far end of the circulating cooling component 32 is connected to the fourth tube body 31, and the near end of the circulating cooling component 32 is adapted to be connected to an external cold source 200. The circulating cooling component 32 is adapted to continuously cool the cooling medium in the fourth tube body 31.
[0123] It should be noted that this should be combined with other information. Figure 6 and Figure 7 As shown, the fourth tube 31 is embedded in the first clamping body 101 on the side away from the second clamping body 102 along the first direction. The fourth tube 31 is located at one end of the first clamping body 101 along the axial direction near the clamp tip 107 to cool the first clamping body 101. The distal end of the fourth tube 31 is closed, and the proximal end of the fourth tube 31 is connected to the circulating cooling assembly 32. The heat transfer between the fourth tube 31 and the circulating cooling assembly 32 is mainly between the high-temperature cooling medium and the low-temperature cooling medium, and there is also at least a partial flow circulation of the cooling medium. During operation, the circulating cooling assembly 32 forms a circulation loop with the external cold source 200. At the same time, the circulating cooling assembly 32 and the fourth tube 31 transfer heat to the external cold source 200, thereby achieving cooling of the first clamping body 101.
[0124] It is worth noting that the fourth tube 31 is located at one end of the first clamping body 101 along the axial direction near the tip 107. This not only cools the first clamping body 101, but also reduces the thickness of the tip 107 along the first direction and the width along the second direction, thereby reducing the volume of the tip 107. While ensuring basic clamping and cutting functions and cooling efficiency, this allows the first clamping body 101 to be more miniaturized, thus preventing the clamp tip from touching nerves or blood vessels in the complex and narrow surgical space, avoiding the risk of heat damage, and greatly improving the safety of electrosurgical procedures.
[0125] In some embodiments, see Figure 6 As shown, the circulating cooling assembly 32 includes a connecting block 321, a fifth pipe body 322 and a sixth pipe body 323. The connecting block 321 is a three-way structure and is adapted to connect the fourth pipe body 31, the fifth pipe body 322 and the sixth pipe body 323 simultaneously.
[0126] The fifth tube 322 and the sixth tube 323 are both located at the proximal end of the first clamping body 101; the distal end of the fifth tube 322 is connected to the connecting block 321, and the proximal end of the fifth tube 322 is adapted to be connected to the cooling medium output port of the external cold source 200; the distal end of the sixth tube 323 is connected to the connecting block 321, and the proximal end of the sixth tube 323 is adapted to be connected to the cooling medium return port of the external cold source 200.
[0127] In this embodiment, by setting a connecting block 321 to connect the fourth tube 31, the fifth tube 322, and the sixth tube 323 simultaneously, the heat in the fourth tube 31 can be conducted to the connecting block 321. Through continuous cooling circulation via the fifth tube 322 and the sixth tube 323, the heat in the fourth tube 31 is conducted to the external cold source 200. This allows the fourth tube 31 to promptly remove the heat from the first clamp 101 without generating excess heat, effectively avoiding damage to surrounding blood vessels or nerves and improving the safety of electrosurgical procedures. At the same time, it allows the first clamp 101 to be more miniaturized, thereby preventing the clamp tip from touching nerves or blood vessels in complex and confined surgical spaces, avoiding the risk of heat damage, and greatly improving the safety of electrosurgical procedures.
[0128] Please combine them together Figure 8 and Figure 9As shown, the following provides an exemplary fourth type of energy surgical active cooling device for monopolar and bipolar metal electrodes under laparoscopy. The cooling structure 103 mainly includes a first plate 41, a second sealing head 42, a seventh tube 43, and an eighth tube 44. The first plate 41, the seventh tube 43, and the eighth tube 44 are all independently arranged relative to the first clamping body 101. The first plate 41 forms a cooling section 411 on the side away from the second clamping body 102 along the first direction, thereby forming an "independent plate and its cooling section - independent dual tube cooling structure".
[0129] In some embodiments, please combine Figure 1 As shown, the first clamping body 101 includes a clamping body 106 and clamping tips 107; please refer to... Figure 9 As shown, the cooling structure 103 includes a first plate 41 and a second sealing head 42;
[0130] The first plate 41 is fixedly disposed on the side of the first clamping body 101 close to the second clamping body 102 along the first direction. The first plate 41 is adapted to abut against the second clamping body 102 to realize the clamping function. A cooling part 411 is formed on the side of the first plate 41 away from the second clamping body 102 along the first direction. The cooling part 411 is disposed at one end of the first plate 41 close to the clamp tip 107 along the axial direction. The cooling part 411 and the first plate 41 are integrally formed.
[0131] Please see Figure 9 As shown, a second receiving groove 412 is formed on the cooling section 411; please refer to the diagram. Figure 8 As shown, the second sealing head 42 is adapted to seal the second receiving groove 412 to close the second receiving groove 412 to form a receiving cavity 104.
[0132] It should be noted that the cooling part 411 and the first plate 41 in this embodiment are integrally formed. Compared with the "independent cooling block-independent dual-pipe cooling structure", in addition to having the beneficial effects of the "independent cooling block-independent dual-pipe cooling structure", it can also make the part to be cooled of the first clamping body 101 disassembled into a single component and directly connected to the water channel, avoiding the need to set up a separate cooling block, thereby further improving the efficiency of cooling and heat dissipation.
[0133] In some embodiments, see Figure 9 As shown, the cooling structure 103 also includes a seventh tube 43 and an eighth tube 44, both of which are disposed on the side of the first clamping body 101 away from the second clamping body 102 along the first direction.
[0134] Please combine them together Figure 8As shown, the distal end of the seventh tube 43 is connected to the receiving cavity 104, and the proximal end of the seventh tube 43 is adapted to be connected to the external cold source 200. The seventh tube 43 is adapted to continuously introduce the cooling medium from the external cold source 200 into the receiving cavity 104.
[0135] The distal end of the eighth tube 44 is connected to the receiving cavity 104, and the proximal end of the eighth tube 44 is adapted to be connected to the external cold source 200. The eighth tube 44 is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity 104 to the external cold source 200.
[0136] In this embodiment, by setting the seventh tube 43 and the eighth tube 44, the cooling part 411 of the first plate 41 and the external cold source 200 form a circulating cooling circuit. Not only will there be no excess heat generation, avoiding redundant heat damage to surrounding blood vessels or nerves, but the cooling efficiency of the cooling structure 103 on the first plate 41 can also be greatly improved.
[0137] Further, please see Figure 9 As shown, two first limiting grooves (not shown in the figure) can be opened on the side of the first plate 41 away from the second clamping body 102 along the first direction, and two second limiting grooves (not shown in the figure) can be opened on both sides of the first clamping body 101 in the second direction, so as to embed the seventh tube 43 and the eighth tube 44 into the first limiting grooves and the second limiting grooves. This not only reduces the risk of damage to the seventh tube 43 and the eighth tube 44, but also helps to optimize the overall structure of the first plate 41 and the first clamping body 101, reduce the volume of the first plate 41 and the first clamping body 101, and facilitate the surgeon to perform more precise cutting or electrocoagulation operations during clinical surgery.
[0138] Please combine them together Figure 10 and Figure 11 As shown, the following exemplarily illustrates a fifth type of energy surgical active cooling device for monopolar and bipolar metal electrodes under laparoscopy. The cooling structure 103 mainly includes a shell 51, a second plate 52, a first through hole 53, a second through hole 54, a ninth tube 55, and a tenth tube 56. The shell 51 is integrally formed with the first clamping body 101. The first through hole 53 and the second through hole 54 are formed on the first clamping body 101. The second plate 52, the ninth tube 55, and the tenth tube 56 are all independently set relative to the first clamping body 101, thereby forming an "integral cooling tank - double deep hole - independent double tube cooling structure".
[0139] In some embodiments, please combine with Figure 1 As shown, the first clamping body 101 includes a clamping body 106 and clamping tips 107; please refer to... Figure 11As shown, the cooling structure 103 includes a housing portion 51, which is disposed at one end of the first clamping body 101 along the axial direction near the clamp tip 107. The housing portion 51 is integrally formed with the first clamping body 101.
[0140] The housing portion 51 is formed by opening a third receiving groove 511 on the side of the first clamping body 102 along the first direction; the cooling structure 103 also includes a second plate 52, which is fixedly disposed on the side of the first clamping body 101 along the first direction near the second clamping body 102. The second plate 52 is adapted to cover the third receiving groove 511 to close the third receiving groove 511 and form a receiving cavity 104.
[0141] It should be noted that, in this embodiment, by setting the housing part 51 and the second plate 52, a closed receiving cavity 104 is formed at the clamp tip 107 position of the first clamping body 101. Compared with any of the previous four energy surgical active cooling devices for monopolar and bipolar metal electrodes applied under laparoscopy, the receiving cavity 104 in this embodiment has a larger volume and contains more cooling medium, which greatly increases the cooling area of the first clamping body 101 and is beneficial to improving the cooling efficiency of the first clamping body 101.
[0142] In some embodiments, see Figure 10 As shown, the first clamping body 101 has a first through hole 53 and a second through hole 54 at its proximal end. The first through hole 53 and the second through hole 54 extend axially toward the position near the clamp tip 107 and are both connected to the third receiving groove 511.
[0143] Please combine them together Figure 11 As shown, the cooling structure 103 also includes a ninth tube 55 and a tenth tube 56, both of which are located at one end of the first clamping body 101 away from the clamp tip 107 along the axial direction.
[0144] The distal end of the ninth tube 55 is connected to the first through hole 53, and the proximal end of the ninth tube 55 is adapted to be connected to the external cold source 200. The ninth tube 55 is adapted to continuously introduce the cooling medium from the external cold source 200 into the receiving cavity 104 through the first through hole 53.
[0145] The distal end of the tenth tube 56 is connected to the second through hole 54, and the proximal end of the tenth tube 56 is adapted to be connected to the external cold source 200. The tenth tube 56 is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity 104 to the external cold source 200 through the second through hole 54.
[0146] It should be noted that a first through hole 53 and a second through hole 54 can be formed on the first clamping body 101 by deep hole machining, so that the first through hole 53 and the second through hole 54 are axially connected to the third receiving groove 511; the second plate 52 can be welded and fixed to the side of the first clamping body 101 close to the second clamping body 102 along the first direction, thereby sealing the third receiving groove 511 and forming a closed receiving cavity 104.
[0147] In this embodiment, by providing the first through hole 53 and the ninth tube 55, as well as the second through hole 54 and the tenth tube 56, the receiving cavity 104 formed by the housing part 51 and the second plate 52 is connected to the external cold source 200 to form a circulating cooling circuit. This not only prevents the generation of excess heat and avoids redundant heat damaging surrounding blood vessels or nerves, but also greatly improves the cooling efficiency of the cooling structure 103 on the first clamping body 101.
[0148] Please combine them together Figure 12 , Figure 13 and Figure 15 As shown, the following provides an exemplary first energy surgical active cooling device for high-frequency bipolar forceps, wherein a cooling structure 103 is disposed on either the first clamping body 101 or the second clamping body 102, thereby forming a "single-sided forceps cooling structure"; the following description uses the first clamping body 101 as an example.
[0149] It should be noted that, Figure 15 The cavity 104 formed at the position of the tweezer tip 109 of the second clamping body 102 is shown in the figure. Figure 15 As shown, the receiving cavity formed by the tweezer tip 109 of the first clamping body 101 can be referenced to the receiving cavity 104 formed by the tweezer tip 109 of the second clamping body 102.
[0150] In some embodiments, see Figure 12 As shown, the first clamping body 101 includes a tweezers body 108 and a tweezers tip 109; please combine them together. Figure 15 As shown, the tip of the tweezers 109 of the first clamping body 101 is hollow and forms a receiving cavity 104.
[0151] Please see Figure 13 As shown, the cooling structure 103 includes an eleventh tube 61 and a twelfth tube 62. The eleventh tube 61 and the twelfth tube 62 are respectively disposed on both sides of the tweezer body 108 of the first clamping body 101 in the second direction and extend axially to the tip of the tweezer tip 109 of the first clamping body 101.
[0152] The distal end of the eleventh tube 61 is connected to the receiving cavity 104, and the proximal end of the eleventh tube 61 is connected to the cooling medium outlet of the external cold source 200. The eleventh tube 61 is adapted to continuously introduce the cooling medium from the external cold source 200 into the receiving cavity 104. The distal end of the twelfth tube 62 is connected to the receiving cavity 104, and the proximal end of the twelfth tube 62 is connected to the cooling medium return port of the external cold source 200. The twelfth tube 62 is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity 104 to the external cold source 200.
[0153] Furthermore, in the manufacturing process, the eleventh tube 61 and the twelfth tube 62 can be embedded in the tweezers body 108 and tweezers tip 109 of the first clamping body 101, so that the distal ends of the eleventh tube 61 and the twelfth tube 62 are simultaneously connected to the receiving cavity 104 at the tip of the tweezers tip 109 of the first clamping body 101, and the proximal ends of the eleventh tube 61 and the twelfth tube 62 are connected to the external cold source 200, thereby forming a circulating cooling circuit between the receiving cavity 104 at the tip of the tweezers tip 109 of the first clamping body 101 and the external cold source 200.
[0154] In this embodiment, by setting the eleventh tube 61 and the twelfth tube 62, the receiving cavity 104 at the tip of the forceps 109 of the first clamping body 101 forms a circulating cooling circuit with the external cold source 200. During operation, the cooling structure 103 and the cooling medium inside it can remove the heat from the tip of the forceps 109 in a timely manner, without generating excess heat. This creates a low-temperature safety zone in the entire circumferential area of the first clamping body 101 and / or the second clamping body 102. This allows the surgeon or physician to selectively use the first clamping body 101 as a fulcrum away from nerves or blood vessels during actual clinical surgery, effectively avoiding redundant heat damage to surrounding blood vessels or nerves caused by both clamping bodies heating up during electrocoagulation or electroresection, greatly improving the safety of electrosurgical procedures. At the same time, it eliminates the heat risk of the heating surface, avoiding the need to set up another heat dissipation structure in the clamping body for simultaneous heat conduction. This not only improves the heat dissipation and cooling efficiency of the clamping body and enhances the safety during clinical surgery, but also simplifies the heat dissipation structure of the clamping body and reduces the technological difficulty of the active cooling device for energy surgery.
[0155] It should be noted that the principle of the "single-sided tweezer cooling structure" of the second clamping body 102 is the same as that of the first clamping body 101, and will not be repeated here.
[0156] Please combine them together Figures 12-15As shown, the following provides an exemplary second energy surgical active cooling device for high-frequency bipolar forceps, wherein a cooling structure 103 is provided on both the first clamping body 101 and the second clamping body 102, thereby forming a "double-sided forceps cooling structure". The cooling structure 103 of the first clamping body 101 has been given in the above embodiment and will not be described again here.
[0157] In some embodiments, see Figure 12 As shown, the second clamping body 102 includes a tweezers body 108 and a tweezers tip 109; please refer to... Figure 15 As shown, the tip of the tweezers 109 of the second clamping body 102 is hollow and forms a receiving cavity 104.
[0158] Please see Figure 14 As shown, the cooling structure 103 includes a thirteenth tube 71 and a fourteenth tube 72. The thirteenth tube 71 and the fourteenth tube 72 are respectively disposed on both sides of the tweezer body 108 of the second clamping body 102 in the second direction, and extend axially to the tip of the tweezer tip 109 of the second clamping body 102.
[0159] The distal end of the thirteenth tube 71 is connected to the receiving cavity 104, and the proximal end of the thirteenth tube 71 is connected to the cooling medium outlet of the external cold source 200. The thirteenth tube 71 is adapted to continuously introduce the cooling medium from the external cold source 200 into the receiving cavity 104. The distal end of the fourteenth tube 72 is connected to the receiving cavity 104, and the proximal end of the fourteenth tube 72 is connected to the cooling medium return port of the external cold source 200. The fourteenth tube 72 is adapted to continuously guide the heat-absorbing cooling medium from the receiving cavity 104 to the external cold source 200.
[0160] It should be noted that, compared with the above-mentioned "single-sided tweezers cooling structure", the "double-sided tweezers cooling structure" in this embodiment can remove the heat from the tips of the tweezers 109 of the two clamping bodies in time during operation, without generating excess heat. This creates a low-temperature safety zone in the entire circumferential area of the first clamping body 101 and the second clamping body 102, thereby further improving the efficiency of cooling and heat dissipation.
[0161] In some embodiments, the energy surgical active cooling device further includes a connecting block 105 disposed between the first clamping body 101 and the second clamping body 102, and the connecting block 105 is adapted to connect the proximal end of the first clamping body 101 to the proximal end of the second clamping body 102.
[0162] It should be noted that, please refer to Figures 1-11As shown, in an energy-assisted surgical active cooling device for monopolar and bipolar metal electrodes used in laparoscopy, the connecting block 105 is adapted to rotatably connect the first clamping body 101 and the second clamping body 102 to achieve basic clamp opening and closing functions; please refer to Figures 12-14 As shown, in an energy surgical active cooling device applied to high-frequency bipolar forceps, the connecting block 105 is adapted to fix the first clamping body 101 and the second clamping body 102 together to achieve a basic forceps tip pinching function. Those skilled in the art can configure the specific structure of the connecting block 105 according to different application scenarios of the energy surgical active cooling device, and are not limited to the above embodiments. Figures 1-14 The situation described in the text.
[0163] According to an embodiment of the present invention, on the other hand, please refer to... Figures 1-17 As shown, an energy surgical active cooling system is also provided, including: an external cold source 200, and an energy surgical active cooling device as described above, wherein the external cold source 200 is adapted to supply a cooling medium to the cooling structure 103.
[0164] The energy surgical active cooling system in this solution includes the aforementioned energy surgical active cooling device. Therefore, the energy surgical active cooling system in this solution includes all the beneficial effects of the aforementioned energy surgical active cooling device.
[0165] It should be noted that, Figure 16 A schematic diagram illustrating the working principle of an active cooling system for laparoscopic monopolar and bipolar metal electrodes in energy surgery is provided. For better explanation and understanding, this embodiment is described in conjunction with the first active cooling device for laparoscopic monopolar and bipolar metal electrodes described above. The distal ends of the first tube 13 and the second tube 14 of the active cooling device are connected to the receiving cavity 104. The proximal end of the first tube 13 can be connected to the cooling medium output port of the external cold source 200, and the proximal end of the second tube 14 can be connected to the cooling medium return port of the external cold source 200. This continuously circulates cooling to the distal heating portions of the first clamping body 101 and / or the second clamping body 102 without generating excess heat. This effectively avoids redundant heat damage to surrounding blood vessels or nerves caused by the clamping body heating during electrocoagulation or electroresection, greatly improving the safety of electrosurgical procedures. The working principle of other active cooling devices for laparoscopic monopolar and bipolar metal electrodes in this active cooling system is the same as that of the first one, and will not be repeated here.
[0166] It should be noted that, Figure 17A schematic diagram illustrating the working principle of an active cooling system for energy surgery applied to high-frequency bipolar forceps is shown. The eleventh tube 61 and twelfth tube 62 (and / or thirteenth tube 71 and fourteenth tube 72) of the active cooling device form a circulating cooling loop with the cavity 104 at the tip of the forceps 109 of the first clamping body 101 (and / or the second clamping body 102) and an external cold source 200. This continuously and cyclically cools the heated portion of the forceps tip 109 of the first clamping body 101 and / or the second clamping body 102 without generating excess heat. This effectively avoids redundant heat damage to surrounding blood vessels or nerves caused by the clamping body heating during electrocoagulation or electroresection, greatly improving the safety of electrosurgical procedures.
[0167] In some embodiments, the energy surgical active cooling system further includes a pumping device 300 adapted to power the circulation of cooling medium between the cooling structure 103 and the external cold source 200.
[0168] Optionally, the pumping device 300 can be a peristaltic pump.
[0169] In this embodiment, the energy surgical active cooling system is equipped with a pumping device 300 to provide power for the circulation of cooling medium between the cooling structure 103 and the external cold source 200. During operation, the circulation flow rate and flow rate of the cooling medium can be adjusted by the pumping device 300, thereby adjusting the cooling effect of the cooling structure 103 on the clamping body.
[0170] In some embodiments, the energy surgical active cooling system further includes a refrigeration device 400 adapted to cool the cooling medium.
[0171] In this embodiment, the energy surgical active cooling system is equipped with a refrigeration device 400 to cool the cooling medium, thereby increasing the temperature difference between the heating part of the clamp and the cooling medium, and improving the cooling efficiency of the cooling structure 103 on the clamp.
