[0092] The energy surgical electrode assembly in the related art cools and dissipates heat through the direction control of the cold-heat conversion by designing a thermoelectric cooling plate in the jaw area and realizing cooling and heat dissipation in the direction of the jaw clamping. However, on the one hand, the basic principle of the thermoelectric cooling plate is to realize refrigeration or heating by using the Peltier effect of semiconductor materials, which is an energy conversion technology. When the direct current power is connected, the temperature of one end of the thermoelectric refrigeration device is reduced, and the temperature of the other end is simultaneously increased. Not only is the refrigeration performance coefficient low, but also the other side will generate new heat due to the principle of refrigeration. This part of heat needs another set of heat dissipation mechanism to conduct heat synchronously. Not only is the structure complex and the process difficult, but also the jaw cooling efficiency is low. On the other hand, the existing energy surgical electrode assembly is only suitable for the clinical operation scene after the fascia around the blood vessels is released. The operation space under this operation scene condition is relatively large, and the heating area on the back of the electric heat refrigeration can be dissipated by natural convection. However, the risk of heat on the heating surface still exists. More importantly, in the actual clinical operation process such as tumor resection and fascia release, the operator actually operates in a very small space, and the surrounding blood vessels and nerves are always in close proximity to the instrument jaw. When both jaws are heated, if the doctor or operator touches the nerve or blood vessel due to fatigue and other inevitable factors, irreversible injury will occur, and there is a great safety risk.
[0093] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0094] The embodiments of the present application will be described below with reference to FIGS. 1 to 17.
[0095] According to the embodiments of the present application, on the one hand, an energy surgical active cooling device is provided, comprising:
[0096] a first clamping body 101;
[0097] a second clamping body 102 connected with the first clamping body 101, and a distal end of the second clamping body 102 being adapted to abut against a distal end of the first clamping body 101;
[0098] a cooling structure 103 arranged 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 is adapted to accommodate a cooling medium;
[0099] The accommodation cavity 104 is in communication with the external cold source 200, and the accommodation cavity 104 is suitable for circulating cooling medium between the accommodation cavity 104 and the external cold source 200, so as to conduct heat on the first clamping body 101 and / or the second clamping body 102 from the distal tip to the external cold source 200.
[0100] It should be noted that, for better understanding, the terms "proximal" and "distal" are defined from the perspective of a doctor (or other operator). Therefore, the term "proximal" is used to indicate the side or end of the device closest to the external body wall and / or the operator, while the term "distal" refers to the structure side or end in the opposite direction of the external body wall and / or the operator.
[0101] It should be noted that the "cooling medium" has thermal conductivity, which 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 limited here.
[0102] It is worth noting that, compared with the heat dissipation mode of the electrode sealing assembly in the related art, the energy surgical active cooling device provided by the present application continuously circulates cooling between the cooling structure 103 and the external cold source 200, so that the cooling medium in the accommodation cavity 104 is always in a good low-temperature cooling state. During operation, the cooling structure 103 and the cooling medium therein not only can timely remove the heat on the opposite side of the first clamping body 101 and the second clamping body 102, but also can timely remove the heat on the side away from 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 region of the first clamping body 101 and / or the second clamping body 102. In the actual clinical operation process, the operator or the physician can selectively use the first clamping body 101 and / or the second clamping body 102 as a fulcrum away from the nerve or blood vessel, effectively avoiding the damage to the surrounding blood vessels or nerves caused by the redundant heat generated during electrocoagulation or electrocision when both clamping bodies are heated, greatly improving the safety of electrosurgical 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 application sets the cooling structure 103, so that the accommodation cavity 104 of the cooling structure 103 is in communication with the external cold source 200, and continuously circulates cooling between the cooling structure 103 and the external cold source 200, eliminating the risk of heat on the heating surface, avoiding the setting of another set of heat dissipation structure in the clamping body to simultaneously conduct heat, not only improving the heat dissipation and cooling efficiency of the clamping body, improving the safety in the clinical operation process, but also simplifying the heat dissipation structure of the clamping body, reducing the process difficulty of the energy surgical active cooling device.
[0103] The energy surgical active cooling device provided by the application, by setting the 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 the accommodating cavity 104, the accommodating cavity 104 is filled with cooling medium, thereby cooling the heat generating part of the first clamping body 101 and / or the second clamping body 102; the accommodating cavity 104 is communicated with the external cold source 200, thereby continuously transferring the heat of the heat generating part to the external cold source 200 through the circulation of the cooling medium, not only eliminating the risk of heat generation surface heat, avoiding setting another set of heat dissipation structure in the clamping body to synchronously conduct heat, improving the heat dissipation and cooling efficiency of the clamping body, but also simplifying the heat dissipation structure of the clamping body, reducing the process difficulty of the energy surgical active cooling device.
[0104] It should be noted that the energy surgical active cooling device provided by the application is mainly applied to the intraoperative active cooling of electrosurgical energy instruments; in order to facilitate better illustration and understanding of the application, the following will be described by taking the energy surgical active cooling device applied to the single-pole and double-pole metal electrode under the endoscope and the energy surgical active cooling device applied to the high-frequency double-pole forceps as examples.
