Description

Technical Field

[0001] This application relates to the field of medical devices, specifically to a cooling and anti-adhesion bipolar electrocoagulation forceps. Background Technology

[0002] Bipolar electrocoagulation forceps, a commonly used hemostatic device in surgical procedures, plays a crucial role in the medical field. With the continuous development of medical technology, the requirements for the precision and safety of surgical equipment are also increasing. Bipolar electrocoagulation forceps utilize high-frequency current to generate heat through human tissue to achieve hemostasis. This working method improves surgical efficiency and safety to a certain extent, reduces bleeding during surgery, and provides strong support for the smooth progress of surgical procedures. It is widely used in various surgical procedures, helping doctors to better perform surgical operations, reduce surgical risks, and play a positive role in patient recovery.

[0003] In the past, traditional bipolar electrocoagulation forceps mostly used solid forceps tips. During operation, the current from the high-frequency host flows through one arm of the forceps to the tip, passes through the gripped tissue, and then returns to the host via the other tip and arm, forming a confined loop. In this process, due to its structural characteristics, the current density tends to concentrate at the edges, creating a "point effect." Simultaneously, the solid structure easily accumulates heat during electrocoagulation, and this heat diffuses to the surrounding area through thermal conduction. Furthermore, the surface of traditional solid electrodes is relatively smooth, causing a large amount of eschar to adhere to the electrode surface during electrocoagulation.

[0004] However, existing solid forceps tips have significant drawbacks. On the one hand, severe eschar adhesion occurs; during electrocoagulation, eschar generated by traditional solid electrodes adheres extensively to the smooth surface of the electrode, reducing conductivity and forcing surgeons to frequently interrupt the procedure to scrape off the eschar, sometimes even causing rebleeding during removal. On the other hand, there are issues with uneven energy distribution and thermal damage diffusion. The current density of solid electrodes tends to concentrate at the edges, creating a "point effect" that leads to uneven tissue heating. Simultaneously, the solid structure easily accumulates heat, which diffuses to surrounding healthy tissue through heat conduction, causing unnecessary collateral damage. Summary of the Invention

[0005] In order to solve the technical problems in the prior art, this application provides a cooling and anti-sticking bipolar electrocoagulation tweezers.

[0006] The cooling and anti-sticking bipolar electrocoagulation tweezers provided in this application adopt the following technical solution:

[0007] A cooling and anti-sticking bipolar electrocoagulation forceps includes two cores. Each core has a forceps tip at its end. A cooling fluid channel extends from the end furthest from the forceps tip towards the forceps tip. The inner surface of the forceps tip forms an electrocoagulation surface for electrocoagulating tissue, and the outer surface forms a non-electrocoagulation surface. Each forceps tip includes a connecting section connected to the core and a working section extending from the connecting section. At least one outlet communicating with the cooling fluid channel is provided on the electrocoagulation surface of the connecting section. A hollow heat dissipation channel is provided inside the working section, and multiple heat dissipation micropores communicating with the hollow heat dissipation channel are provided on the non-electrocoagulation surface of the working section.

[0008] In some embodiments, the hollow heat dissipation channel is a honeycomb structure, a micropore array structure, or a porous groove structure.

[0009] In some embodiments, the cooling and anti-sticking bipolar electrocoagulation forceps further includes two forceps handles and two forceps bars extending from the forceps handles, wherein the forceps handles and the forceps bars are fixedly sleeved on the corresponding core body.

[0010] In some embodiments, anti-slip grooves are formed on the handle of the tweezers.

[0011] In some embodiments, the cooling and anti-sticking bipolar electrocoagulation tweezers further includes a connecting block, the two ends of which are respectively fixedly connected to the two tweezer handles.

[0012] In some embodiments, the cooling and anti-sticking bipolar electrocoagulation tweezers further includes a housing with a sealed receiving cavity inside. The ends of the two cores away from the tweezer tips are both housed in the receiving cavity. The housing is provided with a water inlet hole to allow cooling liquid to enter the receiving cavity and then be discharged from the water outlet through the cooling fluid channel.

[0013] In some embodiments, an insulating spacer is also provided between the two tweezers.

[0014] In some embodiments, the insulating spacer includes an insulating sleeve and an insulating plug, the insulating sleeve and the insulating plug being fixed to the two tweezer rods respectively, and the insulating plug being insertable into the insulating sleeve.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. The bipolar electrocoagulation forceps of this embodiment solves the problems of traditional electrocoagulation forceps through a unique dual heat dissipation system design. The passive heat dissipation system, consisting of hollow heat dissipation channels and heat dissipation micropores, dissipates the heat generated by the forceps tip, reducing heat accumulation. The active cooling system, consisting of cooling fluid channels and outlets, targets and cools the electrocoagulation surface through the flow of cooling fluid, effectively reducing the temperature of the forceps tip and preventing the adhesion of tissue eschar.

[0017] 2. By setting microstructures such as honeycomb structures at the tip of the tweezers, the dense linear contact network formed by its wall-like edges allows the current to be distributed more evenly throughout the entire action area, avoiding local overheating and carbonization, and further reducing collateral damage to surrounding healthy tissues;

[0018] 3. The inclusion of insulating spacers ensures electrical safety and prevents dangerous situations such as electrical leakage. This design improves the efficiency and safety of electrocoagulation forceps, reduces interference during surgery, and provides strong support for the smooth progress of surgical procedures. It represents a significant improvement over traditional solid-tip electrocoagulation forceps. Attached Figure Description

[0026] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 The cooling and anti-adhesion bipolar electrocoagulation forceps provided in this application embodiment include two cores 1, two forceps handles 2, two forceps bars 3, a connecting block 4, a housing 5, and an insulating spacer 6. The two forceps handles 2 and the forceps bars 3 are respectively fixedly sleeved on the corresponding cores 1. The connecting block 4 connects the two forceps handles 2. The forceps tip 11 at the end of the core 1 has heat dissipation and cooling channels. The housing 5 provides a cavity for the cooling fluid and a water inlet 51. The insulating spacer 6 ensures electrical insulation between the forceps bars 3, achieving the effects of reducing the temperature of the forceps tip, preventing tissue adhesion, and reducing thermal damage. This is because the passive heat dissipation through the hollow heat dissipation channel and heat dissipation micropores, as well as the active cooling through the cooling fluid channel and water outlet, effectively removes heat, avoiding heat accumulation and tissue adhesion. At the same time, the insulating spacer 6 improves the safety of use.

[0028] Please refer to Figure 3 Specifically, the core 1 is the core component for achieving conductivity and fluid transport. The core 1 is typically made of a metal material with good conductivity, such as stainless steel, and is shaped like a slender rod to meet the structural requirements of the electrocoagulation tweezers. In some alternative solutions, other alloy materials with similar conductivity can also be used. A cooling fluid channel 12 is formed on the core 1, extending from the end furthest from the tweezer tip 11 towards the tweezer tip 11. This channel can be formed inside the core 1 through machining, and its function is to transport the cooling fluid to the tweezer tip 11.

[0029] Please refer to Figure 2 and Figure 6The forceps tip 11 is a key part for electrocoagulating tissue. In this embodiment, the inner surface of the forceps tip 11 forms an electrocoagulation surface 111 for electrocoagulating tissue, and the outer surface of the forceps tip 11 forms a non-electrocoagulation surface 112. Simultaneously, the forceps tip 11 is divided into two parts along the axial direction: a connecting section 11A connected to the core 1, and a working section 11B extending forward from the connecting section 11A. The electrocoagulation surface 111 typically comes into direct contact with the tissue during surgery for electrocoagulation. The cooling fluid channel 12 inside the core 1 extends to the connecting section 11A. An outlet 114 is provided on the electrocoagulation surface 111 (i.e., the inner surface) of the connecting section 11A, and this outlet 114 communicates with the cooling fluid channel 12. After being transmitted to the connecting section 11A via the cooling fluid channel 12, the cooling fluid is directly discharged from the outlet 114 to rinse and cool the electrocoagulation surface. A hollow heat dissipation channel is provided inside the working section 11B. This hollow heat dissipation channel can be a honeycomb structure, a microporous array structure, or a porous groove structure. Multiple heat dissipation micro-holes 113 are formed on the non-electrocondensing surface 112 (i.e., the outer surface) of the working section 11B. These heat dissipation micro-holes 113 are connected to the internal hollow heat dissipation channels to form a passive heat dissipation system. Since the water outlet 114 is located in the inner connecting section 11A, while the heat dissipation micro-holes 113 are located in the outer working section 11B, the two systems are spatially independent, and the cooling fluid will not enter the internal hollow structure of the working section 11B, thus ensuring functional independence.

[0030] Please refer to Figure 1 The handle 2 is the part where the operator holds the electrocoagulation forceps, and anti-slip grooves 21 are formed on the handle 2. The anti-slip grooves 21 can take various shapes, such as wavy or serrated, and their function is to increase the friction between the operator's hand and the handle 2, preventing the electrocoagulation forceps from slipping during the operation. The handle 2 is usually made of materials with certain elasticity and anti-slip properties, such as plastic or rubber. In alternative solutions, metal materials with special surface treatment can also be used to achieve the anti-slip effect. The forceps bar 3 extends from the handle 2 and is an integral structure with the handle 2. Both the handle 2 and the forceps bar 3 are fixedly sleeved on the corresponding core 1, serving to protect the core 1 and support the forceps tip 11.

[0031] Please refer to Figure 4 and Figure 5 The two ends of the connecting block 4 are fixedly connected to the two tweezer handles 2 respectively. It can be fixed to the tweezer handles 2 by means of a socket connection. The function of the connecting block 4 is to maintain the relative position of the two tweezer arms, making the electrocautery tweezers more stable during use. The connecting block 4 is usually made of metal to ensure its strength and stability.

[0032] Please refer to Figure 1The housing 5 has a sealed cavity inside, and the ends of the two cores 1 furthest from the tweezers tip 11 are both housed within the cavity. A water inlet 51 is provided on the housing 5. The housing 5 can be made of plastic or metal, and its shape depends on the actual design requirements. The function of the water inlet 51 is to allow cooling fluid to enter the cavity. The cooling fluid is typically a liquid with good cooling properties, such as physiological saline. After entering the cavity, the cooling fluid, under pressure, enters the cooling fluid channels 12 at the rear ends of the two cores 1, and is transported along the cores 1 to the tweezers tip 11, finally exiting from the outlet 114 on the electrocoagulation surface 111, thus achieving active and targeted cooling of the electrocoagulation working surface.

[0033] Furthermore, the core 1, as an integral conductive component, has an end furthest from the forceps tip 11 (i.e., the end housed within or extending beyond the housing 5) serving as an electrical connection terminal. In practical use, this electrical connection terminal is connected to an external high-frequency electrosurgical generator (bipolar main unit) via a standard wire plug. When the switch is activated, high-frequency current is conducted through the two cores 1 to the two forceps tips 11 respectively. When the forceps tips grasp human tissue, the current passes through the tissue to form a circuit, generating a thermal effect to achieve the cutting or coagulation function.

[0034] Please refer to Figure 1 The insulating spacer 6 includes an insulating sleeve 61 and an insulating plug 62, which are respectively fixed to the two forceps arms 3. The insulating sleeve 61 and the insulating plug 62 can be made of insulating materials such as plastic and ceramic. The insulating plug 62 can be inserted into the insulating sleeve 61 to achieve a stable insulating connection, ensure electrical insulation between the two electrode arms, and improve surgical safety.

[0035] The implementation principle of this embodiment is as follows: The bipolar electrocoagulation forceps of this embodiment solves the problems existing in traditional electrocoagulation forceps through a unique dual heat dissipation system design. The passive heat dissipation system, composed of a hollow heat dissipation channel and heat dissipation micropores 113, is used to dissipate the heat generated by the forceps tip 11, reducing heat accumulation. The active cooling system, composed of a cooling fluid channel 12 and a water outlet 114, targets and cools the electrocoagulation surface 111 through the flow of cooling fluid, effectively reducing the temperature of the forceps tip 11 and preventing the adhesion of tissue eschar. At the same time, the setting of the insulating spacer 6 ensures electrical safety and avoids dangerous situations such as leakage. This design improves the efficiency and safety of the electrocoagulation forceps, reduces interference during the operation, and provides a strong guarantee for the smooth progress of the surgery, representing a significant improvement compared to traditional solid-tip electrocoagulation forceps.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
