Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a cold circulation device for an energy surgical electrode assembly. Background Technology

[0002] With the development of minimally invasive surgical techniques, endoscopic thyroid surgery has been increasingly widely used in clinical practice due to its advantages such as no neck scars and rapid postoperative recovery. The thyroid region has a complex anatomical structure, with important tissues such as the recurrent laryngeal nerve and parathyroid glands closely distributed around the thyroid gland, and the surgical operating space is extremely narrow, which places extremely high demands on the thermal damage control capabilities of energy instruments.

[0003] Bipolar electrocoagulation forceps are of significant value in endoscopic thyroid surgery due to their reliable hemostasis and relatively controllable thermal damage. When high-frequency current is applied to tissue, the temperature at the electrode working site becomes extremely high, and the heat diffusion effect can cause considerable thermal damage to surrounding normal tissue. In the confined space of endoscopic thyroid surgery, the surgeon must perform delicate operations extremely close to nerves and blood vessels, which can easily lead to fatigue over prolonged surgery. During the procedure, the surgeon often needs to use one of the forceps heads as a fulcrum for support, but both heads of traditional bipolar instruments are heated surfaces, and any contact of either head with surrounding tissue poses a risk of thermal damage.

[0004] To address this issue, existing technologies include cooling solutions based on the principle of thermoelectric cooling plates. Patent application CN122094015A discloses a heat dissipation device that uses a liquid cooling plate to attach to the component to be cooled. However, given the limited space in surgical operations, adding an additional heat dissipation structure results in complex structure, high manufacturing difficulty, and limited cooling efficiency. Patent application CN118121291A discloses an energy surgical active cooling device that cools the forceps head through a built-in cooling chamber. However, the flow pattern of the coolant inside the cooling chamber is difficult to control stably. The coolant tends to flow directly from the inlet to the outlet, failing to fully circulate throughout the entire cooling chamber, resulting in uneven heat exchange distribution and poor cooling consistency. Summary of the Invention

[0005] This invention provides a cold circulation device for an energy surgical electrode assembly to solve the problems of complex structure, difficult manufacturing process, uneven heat exchange distribution and poor cooling consistency caused by additional heat dissipation structures.

[0006] This invention provides a cold circulation device for an energy surgical electrode assembly, comprising a first clamping member, a second clamping member, and a cooling structure; the first clamping member has a first clamping end; the second clamping member is connected to the first clamping member and has a second clamping end, the first clamping end being adapted to abut against the second clamping end; the cooling structure includes a cooling body and a heat dissipation component, the cooling body being disposed on at least one of the first clamping member and the second clamping member, the cooling body having a cooling cavity, the heat dissipation component being disposed within the cooling cavity and connected to the cooling body to form a return liquid channel within the cooling cavity, the end of the return liquid channel near the clamping end being a liquid inlet, the end of the return liquid channel away from the clamping end being a liquid outlet, the liquid inlet and the liquid outlet being adapted to communicate with a cooling source to realize the flow of cooling medium within the return liquid channel.

[0007] Beneficial effects: By installing heat dissipation components inside the cooling chamber, a complete return channel is formed inside the cooling chamber by the cooperation of the heat dissipation components and the cooling body. The cooling medium flows in from the inlet end near the clamping end and flows out from the outlet end away from the clamping end, which increases the contact time and contact area between the cooling medium and the inner wall of the cooling chamber and the heat exchange surface of the clamping head, ensuring the heat exchange distribution in the cooling chamber. At the same time, the inlet end is arranged on the clamping end side, which can prioritize the supply of low temperature cooling medium to the surgical clamping area with the most heat generation, prioritize the suppression of surgical heat diffusion, and reduce the risk of thermal burns to surrounding normal tissues.

[0008] In one optional embodiment, the heat sink includes heat sink fins connected to the cooling body. The heat sink fins have a first end and a second end. The first end of the heat sink fins is connected to the cavity wall of the cooling chamber, and the second end of the heat sink fins is spaced apart from the cavity wall of the cooling chamber. The cooling chamber has a first cavity wall and a second cavity wall facing each other. Multiple heat sink fins are spaced apart, and one of two adjacent heat sink fins is connected to the first cavity wall, while the other of two adjacent heat sink fins is connected to the second cavity wall.

[0009] Beneficial effects: By connecting multiple heat dissipation fins in an alternating manner to the opposing walls on both sides of the cooling chamber, a continuous S-shaped return fluid channel is formed inside the cooling chamber. This ensures that the cooling medium fully fills every space in the cooling chamber, eliminates dead zones in the fluid, and avoids temperature difference defects such as local overcooling or lack of cooling medium in some areas. The multiple heat dissipation fins simultaneously increase the heat exchange area. The metal substrate of the heat dissipation fins can quickly conduct the high-temperature heat generated by the heat dissipation head, and then the heat is continuously carried away by the cooling medium flowing through the surface of the heat dissipation fins, thereby improving the overall heat exchange efficiency.

[0010] In one optional embodiment, the heat dissipation fins include a connecting portion and a guiding portion, the connecting portion and the guiding portion are connected, the end of the connecting portion away from the guiding portion forms a first end, the connecting portion is connected to the cavity wall of the cooling cavity, the guiding portion forms a second end, and the guiding portion extends along the direction from the liquid inlet end to the liquid outlet end.

[0011] Beneficial effects: The guide section extends along the flow direction of the cooling medium. As a fluid guiding surface, the guide section continuously guides the cooling medium to travel in an orderly manner along the return channel, reducing eddies and stagnant areas, ensuring that the cooling medium flows smoothly against the surface of the heat dissipation fins, and making full use of the heat exchange area of ​​the heat dissipation fins.

[0012] In one alternative embodiment, the connecting portions of two adjacent heat dissipation fins are arranged parallel to each other.

[0013] Beneficial effects: The connection parts of adjacent heat dissipation fins are arranged in parallel to each other, forming multiple folding fluid channels of equal width, regularity and uniformity inside the cooling cavity. The flow rate and flow of the cooling medium are evenly distributed in each channel, the heat exchange conditions are uniform throughout the cooling cavity, the cooling rate of each area of ​​the clamping surface is consistent, and there are no local high temperature hot spots.

[0014] In one alternative embodiment, the extending directions of the connecting portions of two adjacent heat dissipation fins form an included angle, which is a right angle.

[0015] Beneficial effects: The inclined intersection of adjacent heat dissipation fins forms a right angle, causing the cooling medium to deflect when it flows through the heat dissipation fins. The inclined arrangement can widen the lateral coverage of the cooling medium, increase the length of the return channel, and improve the cooling effect.

[0016] In one optional embodiment, the cooling body includes a housing and a plate. The housing is disposed on the first clamping member, and the plate is fixedly disposed on the side of the first clamping member near the second clamping member. A cooling groove is formed inside the housing, with the opening of the cooling groove facing the second clamping member. The plate covers the opening of the cooling groove to close the cooling groove and form the cooling cavity. The heat dissipation component is disposed on the plate.

[0017] In one optional embodiment, the cooling body further includes an inlet pipe and a return pipe, both of which are disposed on the side of the first clamping member away from the second clamping member. The first end of the inlet pipe is connected to the inlet end of the return channel, and the second end of the inlet pipe is adapted to be connected to a cooling source. The first end of the return pipe is connected to the outlet end of the return channel, and the second end of the return pipe is adapted to be connected to a cooling source.

[0018] In one optional embodiment, the heat dissipation fins are provided with perforations, and the liquid inlet pipe passes through the perforations on the multiple heat dissipation fins in sequence and communicates with the liquid inlet end.

[0019] Beneficial effects: The liquid inlet pipe passes through the perforations of all the heat dissipation fins and extends to the liquid inlet end of the clamping end, integrating the main liquid supply pipeline into the heat dissipation fin structure inside the cooling cavity, so as to evenly distribute liquid from inside the cavity and solve the defects of local liquid shortage and uneven heat exchange; the perforations play a limiting and fixing role for the liquid inlet pipe, and multiple heat dissipation fins clamp the liquid inlet pipe together, so that the pipeline does not shake or shift in the cooling cavity, and the pipeline position is stable under long-term circulating pressure impact.

[0020] In one optional embodiment, the liquid inlet pipe is provided with a plurality of diversion holes, which are spaced apart, and the liquid outlet direction of the diversion holes is the same as the flow direction of the cooling medium in the liquid return channel.

[0021] Beneficial effects: By opening multiple flow holes on the liquid inlet pipe that runs through the heat sink fins, and ensuring that the liquid outlet direction of the flow holes is consistent with the flow direction of the cooling medium in the return channel, the low-temperature medium is continuously replenished along the fluid flow direction, maintaining the low-temperature state of the medium in the return channel throughout the process. This prevents the problem of the cooling medium temperature rising after flowing for a certain distance and insufficient cooling capacity at the rear end, ensuring uniform cooling effect at all parts of the clamping surface. At the same time, the consistency between the liquid outlet direction of the flow holes and the flow direction of the cooling medium in the return channel helps to facilitate the flow of liquid in the return channel.

[0022] In one optional embodiment, a connecting hole is provided on the housing near the first clamping end, and part of the liquid inlet tube is embedded in the housing and extends out from the connecting hole.

[0023] Beneficial effects: The shell has a connecting hole at the corresponding position of the first clamping end, and part of the liquid inlet tube is embedded inside the shell and extends from the connecting hole to the liquid inlet end of the clamping end, so that the low temperature cooling medium can directly reach the surgical working surface, absorb the high temperature generated by the electrode operation in the first time, and quickly inhibit the heat from spreading to the surrounding tissue.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0031] According to an embodiment of the present invention, a cold circulation device for an energy surgical electrode assembly is provided, comprising a first clamping member 10, a second clamping member 20, and a cooling structure 30; the first clamping member 10 has a first clamping end; the second clamping member 20 is connected to the first clamping member 10 and has a second clamping end, the first clamping end being adapted to abut against the second clamping end; the cooling structure 30 includes a cooling body 31 and a heat dissipation member 32, the cooling body 31 being disposed on the first clamping member 10, the cooling body 31 having a cooling cavity, the heat dissipation member 32 being disposed in the cooling cavity and connected to the cooling body 31 to form a return liquid channel 33 in the cooling cavity, the end of the return liquid channel 33 near the clamping end being an inlet end 331, the end of the return liquid channel 33 away from the clamping end being an outlet end 332, the inlet end 331 and the outlet end 332 being adapted to communicate with a cooling source to realize the flow of cooling medium in the return liquid channel 33.

[0032] Specifically, the first clamping member 10 and the second clamping member 20 are clamps, with the first clamping end and the second clamping end both being clamp tips. The first clamping member 10 and the second clamping member 20 are pivotally connected, and the first clamping end and the second clamping end are abutted and clamped by controlling the rotation of the second clamping member 20.

[0033] It should be noted that in other alternative embodiments, the cooling structure 30 may also be provided on the second clamping member 20, or there may be two cooling structures 30, with one cooling structure 30 provided on each of the first clamping member 10 and the second clamping member 20.

[0034] It should be noted that, referring to Figure 6 As shown in the figure, the cooling circulation structure in the relevant technology still has obvious shortcomings: the flow state of the coolant inside the cooling chamber is difficult to control stably. As shown by the large bifurcation arrow in the figure, the coolant tends to flow directly from the inlet to the outlet, and cannot flow fully through the entire cooling chamber, resulting in uneven heat exchange distribution and poor consistency of cooling.

[0035] The energy surgical electrode assembly cold circulation device of this embodiment uses a heat sink 32 inside the cooling chamber. The heat sink 32 and the cooling body 31 cooperate to form a complete return channel 33 inside the cooling chamber. The cooling medium flows in from the inlet end 331 near the clamping end and flows out from the outlet end 332 away from the clamping end. This increases the contact time and contact area between the cooling medium and the inner wall of the cooling chamber and the heat exchange surface of the clamping head, ensuring the heat exchange distribution in the cooling chamber. At the same time, the inlet end 331 is arranged on the clamping end side, which can prioritize supplying low temperature cooling medium to the surgical clamping area with the most heat generation, preferentially suppressing the spread of surgical heat and reducing the risk of thermal burns to surrounding normal tissues.

[0036] In one embodiment, refer to Figure 1 and Figure 4 As shown, the heat sink 32 includes heat sink fins 321, which are connected to the cooling body 31. The heat sink fins 321 have a first end and a second end. The first end of the heat sink fins 321 is connected to the cavity wall of the cooling chamber, and the second end of the heat sink fins 321 is spaced apart from the cavity wall of the cooling chamber. The cooling chamber has a first cavity wall 34 and a second cavity wall 35 arranged opposite to each other. Multiple heat sink fins 321 are spaced apart. One of two adjacent heat sink fins 321 is connected to the first cavity wall 34, and the other of two adjacent heat sink fins 321 is connected to the second cavity wall 35.

[0037] Specifically, in this embodiment, the heat dissipation fins 321 are metal structures, utilizing the excellent thermal conductivity of metal to achieve rapid heat dissipation and heat exchange.

[0038] Specifically, refer to Figure 2 As shown, the top side wall of the cooling cavity is the first cavity wall 34, and the bottom side wall of the cooling cavity is the second cavity wall 35. The leftmost heat dissipation fin 321 is connected to the second cavity wall 35. The second heat dissipation fin 321 from the left side is connected to the first cavity wall 34. The third heat dissipation fin 321 from the left side is connected to the second cavity wall 35, and so on.

[0039] It is worth noting that by connecting multiple heat dissipation fins 321 in an alternating manner to the opposing cavity walls on both sides of the cooling cavity, a continuous S-shaped return fluid channel 33 is formed inside the cooling cavity. This ensures that the cooling medium fully fills every space in the cooling cavity, eliminates dead zones in the fluid within the cooling cavity, and avoids temperature difference defects such as local overcooling or local lack of cooling medium. The multiple heat dissipation fins 321 simultaneously increase the heat exchange area. The metal substrate of the heat dissipation fins 321 can quickly conduct the high-temperature heat generated by the clamp head, and then the heat is continuously carried away by the cooling medium flowing through the surface of the heat dissipation fins 321, thereby improving the overall heat exchange efficiency.

[0040] In one embodiment, refer to Figure 2 and Figure 3As shown, the heat dissipation fin 321 includes a connecting portion 3211 and a guiding portion 3212. The connecting portion 3211 and the guiding portion 3212 are connected. The end of the connecting portion 3211 away from the guiding portion 3212 forms a first end. The connecting portion 3211 is connected to the cavity wall of the cooling chamber. The guiding portion 3212 forms a second end. The guiding portion 3212 extends along the direction from the liquid inlet end 331 to the liquid outlet end 332.

[0041] Specifically, refer to Figure 3 As shown, the connecting part 3211 and the guide part 3212 are connected to form an "L" shaped structure.

[0042] Specifically, the guide portion 3212 of the upstream heat dissipation fin 321 is arranged toward the connecting portion 3211 of the downstream heat dissipation fin 321 to guide the cooling medium to the downstream heat dissipation fin 321.

[0043] It is worth noting that the guide portion 3212 is designed to prevent the cooling medium from flowing in an oblique direction between two adjacent heat dissipation fins 321, and to prevent part of the structure of the connecting portion 3211 from not being in sufficient contact with the cooling medium.

[0044] It is worth noting that the guide section 3212 extends along the flow direction of the cooling medium. As a fluid guiding surface, the guide section 3212 continuously guides the cooling medium to move in an orderly manner along the return channel 33, reducing eddies and stagnant areas, ensuring that the cooling medium flows smoothly against the surface of the heat dissipation fins 321, and making full use of the heat exchange area of ​​the heat dissipation fins 321.

[0045] In one embodiment, refer to Figure 2 and Figure 4 As shown, the connecting portions 3211 of two adjacent heat dissipation fins 321 are arranged in parallel to each other.

[0046] It is worth noting that the connecting parts 3211 of adjacent heat dissipation fins 321 are arranged in parallel to each other, so that multiple folding fluid channels of equal width, regularity and uniformity are formed inside the cooling cavity. The flow rate and flow of the cooling medium are evenly distributed in each channel, the heat exchange conditions are uniform throughout the cooling cavity, the cooling rate of each area of ​​the clamping surface is consistent, and there are no local high temperature hot spots.

[0047] It should be noted that in other alternative implementation methods, refer to Figure 5 As shown, the extension directions of the connecting portions 3211 of two adjacent heat dissipation fins 321 form an angle, which is a right angle. It is worth noting that the connecting portions 3211 of adjacent heat dissipation fins 321 intersect at an angle to form a right angle, which causes the cooling medium to be deflected when it flows through the heat dissipation fins 321. The inclined arrangement can widen the lateral coverage of the cooling medium, increase the length of the return channel 33, and improve the cooling effect.

[0048] In one embodiment, refer to Figure 1As shown, the cooling body 31 includes a housing 311 and a plate 312. The housing 311 is disposed on the first clamping member 10, and the plate 312 is fixedly disposed on the side of the first clamping member 10 near the second clamping member 20. A cooling groove is formed inside the housing 311, and the opening of the cooling groove faces the second clamping member 20. The plate 312 covers the opening of the cooling groove to close the cooling groove and form a cooling cavity. The heat dissipation component 32 is disposed on the plate 312.

[0049] Specifically, the plate 312 is a metal structure, and the plate 312 and the heat sink 32 are made of the same material to facilitate rapid heat exchange and heat dissipation.

[0050] Specifically, the housing 311 and the first clamping member 10 are integrally formed.

[0051] In one embodiment, refer to Figure 1 As shown, the cooling body 31 also includes an inlet pipe 313 and a return pipe 314. Both the inlet pipe 313 and the return pipe 314 are located on the side of the first clamping member 10 away from the second clamping member 20. The first end of the inlet pipe 313 is connected to the inlet end 331 of the return channel 33, and the second end of the inlet pipe 313 is adapted to be connected to the cooling source. The first end of the return pipe 314 is connected to the outlet end 332 of the return channel 33, and the second end of the return pipe 314 is adapted to be connected to the cooling source.

[0052] In one embodiment, refer to Figure 2 As shown, the heat dissipation fins 321 have perforations, and the liquid inlet pipe 313 passes through the perforations on multiple heat dissipation fins 321 in sequence and is connected to the liquid inlet end 331.

[0053] Specifically, in this embodiment, the perforation is located at the center of the connecting portion 3211.

[0054] It is worth noting that the liquid inlet pipe 313 passes through the perforations of all the heat dissipation fins 321 and extends to the liquid inlet end 331 of the clamping end. The main liquid supply pipeline is integrated into the heat dissipation fin 321 structure inside the cooling cavity, so as to distribute the liquid evenly from inside the cavity and solve the defects of local liquid shortage and uneven heat exchange. The perforations play a role in limiting and fixing the liquid inlet pipe 313. Multiple heat dissipation fins 321 clamp the liquid inlet pipe 313 together, so the pipeline does not shake or shift in the cooling cavity, and the pipeline position is stable under long-term circulating pressure impact.

[0055] In one embodiment, refer to Figure 2 and Figure 3 As shown, the liquid inlet pipe 313 is provided with multiple diversion holes 3131, which are spaced apart. The liquid outlet direction of the diversion holes 3131 is the same as the flow direction of the cooling medium in the return channel 33.

[0056] Specifically, refer to Figure 3As shown, a diversion hole 3131 is provided on the liquid inlet pipe 313 between two adjacent heat dissipation fins 321.

[0057] It should be noted that in other alternative embodiments, the number of diversion holes 3131 can be adjusted according to the actual situation.

[0058] It is worth noting that by opening multiple flow holes 3131 on the liquid inlet pipe 313 that penetrates the heat dissipation fins 321, the liquid outlet direction of the flow holes 3131 is consistent with the flow direction of the cooling medium in the return channel 33. The low-temperature medium is continuously replenished along the fluid flow direction, maintaining the low-temperature state of the medium in the return channel 33 throughout the process. This avoids the problem of the cooling medium temperature rising after flowing for a certain distance and insufficient cooling capacity at the rear end, ensuring uniform cooling effect at all parts of the clamping surface. At the same time, the consistency between the liquid outlet direction of the flow holes and the flow direction of the cooling medium in the return channel 33 helps to facilitate the flow of liquid in the return channel 33.

[0059] It should be noted that in other alternative implementation methods, refer to Figure 5 As shown, a connecting hole is provided on the housing 311 near the first clamping end, and a portion of the liquid inlet pipe 313 is embedded in the housing 311 and extends out through the connecting hole. It is worth noting that the connecting hole is provided on the housing 311 at the corresponding position of the first clamping end, and a portion of the liquid inlet pipe 313 is embedded inside the housing 311 and extends from the connecting hole to the liquid inlet end 331 of the clamping end, so that the low-temperature cooling medium can directly reach the surgical working surface, absorb the high temperature generated by the electrode operation in the first time, and quickly suppress the heat diffusion to the surrounding tissue.

[0060] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and all such modifications and variations fall within the scope defined by the appended claims.
