Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and in particular to an energy surgery active cooling device and an energy surgery active cooling system. Background Art

[0002] Energy medical devices are mainly used in electrosurgery for tissue cutting and blood vessel or tissue sealing. The problem of thermal diffusion damage to adjacent or surrounding tissues caused by the thermal diffusion of the electrode at the closed position is an important issue that needs to be solved in the current clinical surgery process.

[0003] Existing energy surgical electrode assemblies usually utilize the principle of thermoelectric cooling plates, design thermoelectric cooling plates in the clamp head area, and control the direction of heat conversion to achieve cooling and heat dissipation in the clamp head clamping direction. However, 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 a DC power supply is connected, the temperature of one end of the thermoelectric cooling device will decrease, while the temperature of the other end will increase at the same time. Due to this principle, while cooling one side, new heat will be generated on the other side. This part of the heat requires another set of heat dissipation mechanisms to conduct heat simultaneously. Therefore, the existing energy surgical electrode assemblies are not only complex in structure and difficult in process, but also have low cooling efficiency of the clamp head. Utility Model Content

[0089] In the energy surgical electrode assembly in the related art, by utilizing the principle of a thermoelectric cooling plate, a thermoelectric cooling plate is designed in the jaw area. By controlling the direction of the cold and heat conversion, cooling and heat dissipation are achieved in the jaw clamping direction. However, on the one hand, since the basic principle of the thermoelectric cooling plate is an energy conversion technology that uses the Peltier effect of semiconductor materials to achieve refrigeration or heating, when a DC power supply is connected, the temperature of one end of the thermoelectric refrigeration device will decrease, while the temperature of the other end will increase simultaneously. Not only is the coefficient of performance of refrigeration low, but also due to this principle, new heat will be generated on the other side while cooling one side. This part of the heat requires another set of heat dissipation mechanisms to conduct heat synchronously. Not only is the structure complex and the process difficult, but also the cooling efficiency of the jaw is relatively low. On the other hand, the existing energy surgical electrode assembly is only applicable to the clinical surgical scenario after the fascia around the blood vessels has been dissected. In this surgical scenario, the surgical space is relatively large, allowing the heat generation area on the back of the electrothermal refrigeration to dissipate heat through natural convection and other means. However, the risk of heat on the heating surface still exists in essence. More importantly, during actual clinical surgeries such as tumor resection and fascia dissection, the surgeon is actually operating in a very narrow space, and the surrounding blood vessels and nerves are always very close to the instrument jaws. When both jaws of the bipolar are heated, if the physician or surgeon touches a nerve or blood vessel with any one of the two jaws due to inevitable factors such as fatigue, irreparable trauma will occur, posing a great safety risk.

[0090] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0091] The following combines Figures 1 to 17 , and describes the embodiments of the present invention.

[0092] According to an embodiment of the present invention, on the one hand, an energy surgical active cooling device is provided, including:

[0093] A first clamping body 101;

[0094] A second clamping body 102, 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, and a cooling medium is adapted to be received in the receiving cavity 104;

[0096] The receiving cavity 104 is in communication with an external cold source 200, and the receiving cavity 104 is adapted to circulate a cooling medium between the receiving cavity 104 and the external cold source 200, so as to conduct the heat on 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 a doctor (or other surgeon). Therefore, the term "proximal (end / side)" is used to indicate the side or end of the device closest to the external body wall and / or the surgeon or a part thereon, while the term "distal (end / side)" refers to the side or end of the structure in the opposite direction 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 mixed cooling medium; the specific composition of the cooling medium can be configured according to actual clinical needs and is not specifically limited herein.

[0099] It should be noted that, compared with the heat dissipation method of the electrode sealing assembly in the related art, the energy surgical active cooling device provided by the present utility model enables the cooling medium in the accommodation cavity 104 to always be in a good low-temperature cooling state through the continuous cooling cycle between the cooling structure 103 and the external cold source 200; during the working process, the cooling structure 103 and the cooling medium therein can not only timely take away the heat on the opposite side of the first clamping body 101 and the second clamping body 102, but also timely take away the heat on the opposite side of the first clamping body 101 and the second clamping body 102, and at the same time, no extra heat is generated, so that a low-temperature safety zone is formed in the entire circumferential area of the first clamping body 101 and / or the second clamping body 102, facilitating the surgeon or physician to selectively use the first clamping body 101 and / or the second clamping body 102 as a fulcrum away from nerves or blood vessels during the actual clinical operation, effectively avoiding the redundant heat generated during electrocoagulation or electrosection due to both clamping bodies generating heat and damaging the surrounding blood vessels or nerves, greatly improving the safety of the electro-surgical operation; compared with the heat dissipation structure of the electrode sealing assembly in the related art, the energy surgical active cooling device provided by the present utility model is provided with a cooling structure 103, so that the accommodation cavity 104 of the cooling structure 103 is communicated with the external cold source 200, and through the continuous cooling cycle between the cooling structure 103 and the external cold source 200, the heat risk of the heating surface is eliminated, and the need to set up another set of heat dissipation structure in the clamping body to conduct heat synchronously is avoided. This not only improves the heat dissipation and cooling efficiency of the clamping body and the safety during the clinical operation, but also simplifies the heat dissipation structure of the clamping body and reduces the process difficulty of the energy surgical active cooling device.

[0100] The energy surgical active cooling device provided by the present utility model cools and reduces the temperature of the heating part of the first clamping body 101 and / or the second clamping body 102 by arranging 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 inside and forms an accommodation cavity 104, and the accommodation cavity 104 accommodates a cooling medium, so as to cool and reduce the temperature of the heating part of the first clamping body 101 and / or the second clamping body 102; the accommodation cavity 104 is communicated with the external cold source 200, so that the heat of the heating part is continuously transferred to the external cold source 200 through the circulation of the cooling medium. This not only eliminates the heat risk of the heating surface, avoids setting up another set of heat dissipation structure in the clamping body to conduct heat synchronously, improves the heat dissipation and cooling efficiency of the clamping body, but also simplifies the heat dissipation structure of the clamping body and reduces the process difficulty of the energy surgical active cooling device.

[0101] It should be noted that the active cooling device for energy surgery provided by the present utility model is mainly applied to the active cooling during electro-surgical energy instruments. For better illustration and understanding of the present utility model, the following will specifically take the active cooling device for energy surgery applied to single and bipolar metal electrodes under laparoscopy and the active cooling device for energy surgery applied to high-frequency bipolar forceps as examples for illustration respectively.

The cooling block body 11 is fixedly arranged 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 is arranged in a fitting manner with the side of the first clamping body 101 away from the second clamping body 102 along the first direction 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, facilitate the cooling block body 11 to take away the heat on the clamping body in time, and is beneficial to improving the cooling efficiency and avoiding redundant heat from damaging the surrounding blood vessels or nerves;

[0105] A first accommodation groove 111 is formed on the cooling block body 11; the first plugging head 12 is suitable for plugging the first accommodation groove 111 to enclose the first accommodation groove 111 to form an accommodation cavity 104, thereby reducing the processing difficulty of the first accommodation groove 111 and the assembly difficulty of the cooling structure 103.

[0106] Furthermore, please refer to Figure 3 As shown, a counterbore (not shown in the figure) can be formed at the tip position of the forceps tip 107 of the first clamping body 101. The counterbore is suitable for being arranged in a fitting manner and fixedly connected with one side of the cooling block body 11.

[0107] In some embodiments, please refer to Figure 3As shown, the cooling structure 103 further includes a first tube body 13 and a second tube body 14.

[0110] In this embodiment, by arranging the first tube body 13 and the second tube body 14, a circulating cooling circuit is formed between the cooling block body 11 and the external cold source 200. Not only will there be no excess heat generation, avoiding damage to surrounding blood vessels or nerves caused by redundant heat, but also the cooling efficiency of the cooling structure 103 for the first clamping body 101 can be greatly improved.

[0111] Furthermore, please refer to 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 body 13 and the second tube body 14 in the limiting groove. This can not only reduce the risk of damage to the first tube body 13 and the second tube body 14, but also be beneficial to optimizing the overall structure of the first clamping body 101, reducing the volume of the first clamping body 101, and facilitating more refined cutting or electrocoagulation operations by the operator during clinical surgery.

[0112] It can be understood that in the specific implementation process, technicians can adjust the specific structure and dimensions of the side of the first clamping body 101 away from the second clamping body 102 according to the actual shapes and dimensions of the cooling block body 11, the first plugging head 12, the first tube body 13 and the second tube body 14, not limited to the situation described in this embodiment.

[0113] Please also refer to Figure 4 and Figure 5 As shown, the following exemplarily gives a second energy surgical active cooling device applied to a single / double-pole metal electrode under a laparoscope.

The input end of the third tube body 21 is communicated with the cooling medium output port of the external cold source 200, and the output end of the third tube body 21 is communicated with the cooling medium return port of the external cold source 200. The cooling medium is adapted to circulate in the third tube body 21 to cool the first clamping body 101.

[0116] In this embodiment, the input end of the third tube body 21 is communicated with the cooling medium output port of the external cold source 200, and the output end of the third tube body 21 is communicated with the cooling medium return port of the external cold source 200, so as to form a circulating cooling loop with the external cold source 200; during the working process, the third tube body 21 can timely take away the heat on both sides of the first clamping body 101 in the first direction, and there will be no excessive heat generation at the same time, so as to form a low-temperature safety zone in the entire circumferential area of the first clamping body 101, thereby effectively avoiding damage to the surrounding blood vessels or nerves and greatly improving the safety of electro-surgical operations; on the other hand, the third tube body 21 is an integrally formed "U" - shaped structure, without additional heat dissipation components and sealing components, greatly simplifying the cooling structure and reducing the process difficulty.

[0117] Furthermore, please refer to Figure 5 As shown, a "U" - shaped limiting groove (not shown in the figure) can be formed at the edge position of the first clamping body 101 to embed the third tube body 21 in the limiting groove, which can not only reduce the damage risk of the third tube body 21, but also help to optimize the overall structure of the first clamping body 101, reduce the volume of the first clamping body 101, and facilitate more refined cutting or electrocoagulation operations by the surgeon during the clinical operation.

[0118] It can be understood that in the specific implementation process, the technical personnel can 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 body 21, not limited to the situation described in this embodiment.

[0119] Please also combine with Figure 6 and Figure 7As shown below, an exemplary third energy surgical active cooling device applied to a single and bipolar metal electrode under a laparoscope is given. Among them, the cooling structure 103 mainly includes a fourth tube body 31 and a circulating cooling assembly 32. The fourth tube body 31 and the circulating cooling assembly 32 are both independently arranged with the first clamping body 101. Among them, the circulating cooling assembly 32 mainly includes a connecting block 321, a fifth tube body 322 and a sixth tube body 323, thus forming an "independent three-way block - independent three-tube body cooling structure".

[0120] In some embodiments, please refer to Figure 1 As shown, the first clamping body 101 includes a clamp body 106 and a clamp tip 107; please refer to Figure 6 As shown, the cooling structure 103 includes a fourth tube body 31 and a circulating cooling assembly 32. The fourth tube body 31 and the circulating cooling assembly 32 are arranged on the side of the first clamping body 101 away from the second clamping body 102 along the first direction;

[0121] The fourth tube body 31 is arranged at one end of the first clamping body 101 close to the clamp tip 107 along the axial direction. The fourth tube body 31 is adapted to accommodate a cooling medium to cool down the first clamping body 101;

[0122] The circulating cooling assembly 32 is arranged at one end of the first clamping body 101 close to the clamp body 106 along the axial direction. The distal end of the circulating cooling assembly 32 is connected to the fourth tube body 31, and the proximal end of the circulating cooling assembly 32 is adapted to be connected to an external cold source 200. The circulating cooling assembly 32 is adapted to continuously cool down the cooling medium in the fourth tube body 31.

[0123] It should be noted that, please refer to Figure 6 and Figure 7 As shown, the fourth tube body 31 is embedded in the side of the first clamping body 101 away from the second clamping body 102 along the first direction. The fourth tube body 31 is arranged at one end of the first clamping body 101 close to the clamp tip 107 along the axial direction to cool down the first clamping body 101; the distal end of the fourth tube body 31 is closed, and the proximal end of the fourth tube body 31 is connected to the circulating cooling assembly 32. Between the fourth tube body 31 and the circulating cooling assembly 32, it is mainly in the form of heat conduction between the high-temperature cooling medium and the low-temperature cooling medium, and there is also at least partial flow circulation of the cooling medium; during the working process, the circulating cooling assembly 32 and the external cold source 200 form a circulation loop. At the same time, heat transfer occurs between the circulating cooling assembly 32 and the fourth tube body 31 to conduct the heat on the first clamping body 101 to the external cold source 200, thereby realizing the cooling of the first clamping body 101.

[0124] It should be noted that the fourth tube body 31 is arranged at one end of the first clamping body 101 close to the clamp tip 107 along the axial direction. It can not only cool down the first clamping body 101, but also reduce the thickness of the first clamping body 101 at the position of the clamp tip 107 along the first direction and the width along the second direction, thereby reducing the volume of the clamp tip 107. On the premise of ensuring the basic clamping and cutting functions and cooling efficiency, the first clamping body 101 can be made more miniaturized, so as to avoid the clamp head touching nerves or blood vessels in a complex and narrow surgical space and avoid the risk of heat damage, greatly improving the safety of electro-surgical operations.

[0125] In some embodiments, please refer to Figure 6 As shown, the circulating cooling assembly 32 includes a connecting block 321, a fifth tube body 322 and a sixth tube body 323. Among them, the connecting block 321 has a tee structure, and the connecting block 321 is adapted to connect the fourth tube body 31, the fifth tube body 322 and the sixth tube body 323 in communication at the same time;

[0126] Both the fifth tube body 322 and the sixth tube body 323 are arranged at the proximal end of the first clamping body 101; the distal end of the fifth tube body 322 is connected to the connecting block 321, and the proximal end of the fifth tube body 322 is adapted to be connected to the cooling medium outlet of the external cold source 200; the distal end of the sixth tube body 323 is connected to the connecting block 321, and the proximal end of the sixth tube body 323 is adapted to be connected to the cooling medium return port of the external cold source 200.

[0127] In this embodiment, by arranging the connecting block 321 to connect the fourth tube body 31, the fifth tube body 322 and the sixth tube body 323 in communication at the same time, the heat in the fourth tube body 31 can be conducted into the connecting block 321 and continuously circulated and cooled through the fifth tube body 322 and the sixth tube body 323, so as to conduct the heat in the fourth tube body 31 to the external cold source 200. Thus, the fourth tube body 31 can take away the heat of the first clamping body 101 in time without generating excessive heat, effectively avoiding damage to surrounding blood vessels or nerves and improving the safety of electro-surgical operations; at the same time, the first clamping body 101 can be made more miniaturized, so as to avoid the clamp head touching nerves or blood vessels in a complex and narrow surgical space and avoid the risk of heat damage, greatly improving the safety of electro-surgical operations.

[0130] The first plate body 41 is fixedly arranged on one side of the first clamping body 101 close to the second clamping body 102 along the first direction. The first plate body 41 is adapted to abut against the second clamping body 102 to achieve the clamping function; a cooling part 411 is formed on one side of the first plate body 41 away from the second clamping body 102 along the first direction.

[0132] It should be noted that the cooling part 411 and the first plate body 41 in this embodiment are of an integrally formed structure. Compared with the "independent cooling block - independent double-tube body cooling structure", in addition to having the beneficial effects of the "independent cooling block - independent double-tube body cooling structure", it can also make the part of the first clamping body 101 to be cooled disassembled into a component directly connected to the water path, avoiding the separate setting of the cooling block, thereby further improving the cooling and heat dissipation efficiency.

[0133] In some embodiments, please refer to Figure 9 As shown, the cooling structure 103 further includes a seventh tube body 43 and an eighth tube body 44. The seventh tube body 43 and the eighth tube body 44 are both arranged on one side of the first clamping body 101 away from the second clamping body 102 along the first direction;

[0136] In this embodiment, by providing the seventh tube body 43 and the eighth tube body 44, a circulating cooling circuit is formed between the cooling part 411 of the first plate body 41 and the external cold source 200. Not only will there be no excess heat generation, avoiding damage to surrounding blood vessels or nerves caused by redundant heat, but also the cooling efficiency of the cooling structure 103 for the first plate body 41 can be greatly improved.

[0137] Furthermore, please refer to Figure 9 As shown, two first limiting grooves (not shown in the figure) can be provided on the side of the first plate body 41 away from the second clamping body 102 along the first direction. At the same time, two second limiting grooves (not shown in the figure) are respectively provided on both sides of the first clamping body 101 in the second direction, so as to embed the seventh tube body 43 and the eighth tube body 44 in the first limiting groove and the second limiting groove. This can not only reduce the risk of damage to the seventh tube body 43 and the eighth tube body 44, but also help to optimize the overall structure of the first plate body 41 and the first clamping body 101, reduce the volume of the first plate body 41 and the first clamping body 101, and facilitate more refined cutting or electrocoagulation operations by the operator during clinical surgery.

[0138] Please also refer to Figure 10 and Figure 11 As shown, the following exemplarily gives a fifth type of energy surgical active cooling device applied to a single and bipolar metal electrode under a laparoscope. Among them, the cooling structure 103 mainly includes a housing part 51, a second plate body 52, a first through hole 53, a second through hole 54, a ninth tube body 55 and a tenth tube body 56. Among them, the housing part 51 is integrally formed with the first clamping body 101, the first through hole 53 and the second through hole 54 are provided on the first clamping body 101, and the second plate body 52, the ninth tube body 55 and the tenth tube body 56 are all independently provided relative to the first clamping body 101, thus forming an "integral cooling groove - double deep holes - independent double tube body cooling structure".

[0139] In some embodiments, please refer to Figure 1 As shown, the first clamping body 101 includes a forceps body 106 and a forceps tip 107; please refer to Figure 11As shown, the cooling structure 103 includes a housing portion 51. The housing portion 51 is disposed at one end of the first clamping body 101 near the clamp tip 107 along the axial direction, and the housing portion 51 is integrally formed with the first clamping body 101.

[0140] On one side of the housing portion 51 close to the second clamping body 102 along the first direction, a third receiving groove 511 is formed by opening. The cooling structure 103 further includes a second plate body 52. The second plate body 52 is fixedly disposed on one side of the first clamping body 101 close to the second clamping body 102 along the first direction. The second plate body 52 is adapted to cover the third receiving groove 511 to enclose the third receiving groove 511 to form a receiving cavity 104.

[0141] It should be noted that in this embodiment, by providing the housing portion 51 and the second plate body 52, a closed receiving cavity 104 is formed around the clamp tip 107 position of the first clamping body 101. Compared with any one of the first four energy surgical active cooling devices applied to single and bipolar metal electrodes under the endoscope, the volume of the receiving cavity 104 in this embodiment is larger, and the amount of cooling medium contained is more, greatly increasing the cooling area of the first clamping body 101, which is beneficial to improving the cooling efficiency of the first clamping body 101.

[0142] In some embodiments, please refer to Figure 10 As shown, a first through hole 53 and a second through hole 54 are formed at the proximal end of the first clamping body 101. The first through hole 53 and the second through hole 54 respectively extend along the axial direction towards the position close to the clamp tip 107 and are both connected to the third receiving groove 511.

[0143] Please also refer to Figure 11 As shown, the cooling structure 103 further includes a ninth pipe body 55 and a tenth pipe body 56.

[0144] The distal end of the ninth pipe body 55 is connected to the first through hole 53, and the proximal end of the ninth pipe body 55 is adapted to be connected to an external cold source 200. The ninth pipe body 55 is adapted to continuously introduce the cooling medium from the external cold source 200 into the receiving cavity 104 via the first through hole 53.

[0145] The distal end of the tenth pipe body 56 is connected to the second through hole 54, and the proximal end of the tenth pipe body 56 is adapted to be connected to an external cold source 200. The tenth pipe body 56 is adapted to continuously guide the heat-absorbed cooling medium from the receiving cavity 104 to the external cold source 200 via the second through hole 54.

[0146] It should be noted that the first through hole 53 and the second through hole 54 can be formed by deep hole machining on the first clamping body 101, so that both the first through hole 53 and the second through hole 54 are axially communicated with the third receiving groove 511; the second plate body 52 can be fixedly welded to the side of the first clamping body 101 close to the second clamping body 102 along the first direction, so as to cover the third receiving groove 511 and form a closed receiving cavity 104.

[0147] In this embodiment, by providing the first through hole 53 and the ninth tube body 55, and the second through hole 54 and the tenth tube body 56, a circulating cooling circuit is formed between the receiving cavity 104 formed by enclosing the housing part 51 and the second plate body 52 and the external cold source 200. There will not be any redundant heat generation, avoiding damage to surrounding blood vessels or nerves caused by redundant heat, and moreover, the cooling efficiency of the cooling structure 103 for the first clamping body 101 can be greatly improved.

[0148] Please also refer to Figure 12 、 Figure 13 and Figure 15 As shown, the following exemplarily gives the first energy surgical active cooling device applied to a high-frequency bipolar forceps. Among them, the cooling structure 103 is arranged on any one of the first clamping body 101 and the second clamping body 102, so as to form a "single-sided forceps body cooling structure"; the following takes the first clamping body 101 as an example for description.

[0149] It should be noted that Figure 15 shows the receiving cavity 104 formed at the position of the forceps tip 109 of the second clamping body 102. As can be seen from Figure 15 shown, the receiving cavity formed at the position of the forceps tip 109 of the first clamping body 101 can refer to the receiving cavity 104 formed at the position of the forceps tip 109 of the second clamping body 102.

[0150] In some embodiments, please refer to Figure 12 shown, the first clamping body 101 includes a forceps body 108 and a forceps tip 109; please also refer to Figure 15 shown, the tip position of the forceps tip 109 of the first clamping body 101 is hollow inside and forms a receiving cavity 104;

[0151] Please refer to Figure 13 shown, the cooling structure 103 includes an eleventh tube body 61 and a twelfth tube body 62. The eleventh tube body 61 and the twelfth tube body 62 are respectively arranged on both sides of the second direction of the forceps body 108 of the first clamping body 101 and axially extend to the tip position of the forceps tip 109 of the first clamping body 101;

[0152] The distal end of the eleventh tube body 61 is in communication with the accommodation cavity 104, and the proximal end of the eleventh tube body 61 is in communication with the cooling medium outlet of the external cold source 200. The eleventh tube body 61 is adapted to continuously introduce the cooling medium from the external cold source 200 into the accommodation cavity 104; the distal end of the twelfth tube body 62 is in communication with the accommodation cavity 104, and the proximal end of the twelfth tube body 62 is in communication with the cooling medium return port of the external cold source 200. The twelfth tube body 62 is adapted to continuously direct the heat-absorbed cooling medium from the accommodation cavity 104 to the external cold source 200.

[0153] Further, in the manufacturing process, the eleventh tube body 61 and the twelfth tube body 62 can be embedded in the tweezer body 108 and the tweezer tip 109 of the first clamping body 101, and the distal ends of the eleventh tube body 61 and the twelfth tube body 62 are simultaneously in communication with the accommodation cavity 104 at the tip position of the tweezer tip 109 of the first clamping body 101, and the proximal ends of the eleventh tube body 61 and the twelfth tube body 62 are in communication with the external cold source 200, so that a circulating cooling circuit is formed between the accommodation cavity 104 at the tip position of the tweezer tip 109 of the first clamping body 101 and the external cold source 200.

[0154] In this embodiment, by providing the eleventh tube body 61 and the twelfth tube body 62, a circulating cooling circuit is formed between the accommodation cavity 104 at the tip position of the tweezer tip 109 of the first clamping body 101 and the external cold source 200; during the working process, the cooling structure 103 and the cooling medium therein can timely take away the heat at the tip of the tweezer tip 109, and at the same time, no extra heat is generated, so that a low-temperature safety zone is formed in the entire circumferential area of the first clamping body 101 and / or the second clamping body 102, which is convenient for the surgeon or physician to selectively use the first clamping body 101 as a fulcrum away from nerves or blood vessels during the actual clinical operation, effectively avoiding the redundant heat generated during electrocoagulation or electrosection due to the heating of both clamping bodies, which greatly improves the safety of the electrosurgical operation; at the same time, the heat risk of the heating surface is eliminated, and the need to set up another set of heat dissipation structures in the clamping body to conduct heat synchronously is avoided, which not only improves the heat dissipation and cooling efficiency of the clamping body, improves the safety during the clinical operation process, but also simplifies the heat dissipation structure of the clamping body and reduces the process difficulty of the energy surgical active cooling device.

[0155] It should be noted that the principle of the "single-side tweezer body cooling structure" of the second clamping body 102 is the same as that of the first clamping body 101, and will not be elaborated here.

[0156] Please also combine Figures 12 - 15As shown below, an exemplary second energy surgical active cooling device applied to a high-frequency bipolar forceps is given. Among them, cooling structures 103 are provided on both the first clamping body 101 and the second clamping body 102, thus forming a "bilateral forceps body cooling structure". The cooling structure 103 of the first clamping body 101 has been given in the above embodiment and will not be elaborated here.

[0157] In some embodiments, please refer to Figure 12 As shown, the second clamping body 102 includes a forceps body 108 and a forceps tip 109; please refer to Figure 15 As shown, the tip of the forceps tip 109 of the second clamping body 102 is hollow inside and forms a receiving cavity 104;

[0158] Please refer to Figure 14 As shown, the cooling structure 103 includes a thirteenth tube body 71 and a fourteenth tube body 72. The thirteenth tube body 71 and the fourteenth tube body 72 are respectively arranged on both sides of the second direction of the forceps body 108 of the second clamping body 102 and axially extend to the tip position of the forceps tip 109 of the second clamping body 102;

[0159] The distal end of the thirteenth tube body 71 is communicated with the receiving cavity 104, the proximal end of the thirteenth tube body 71 is communicated with the cooling medium outlet of the external cold source 200, and the thirteenth tube body 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 body 72 is communicated with the receiving cavity 104, the proximal end of the fourteenth tube body 72 is communicated with the cooling medium return port of the external cold source 200, and the fourteenth tube body 72 is adapted to continuously guide the heat-absorbed cooling medium from the receiving cavity 104 to the external cold source 200.

[0160] It should be noted that, compared with the above "unilateral forceps body cooling structure", in the working process of the "bilateral forceps body cooling structure" in this embodiment, the cooling structure 103 and the cooling medium therein can timely take away the heat at the tips of the forceps tips 109 of the two clamping bodies, and there will be no excess heat generation.
