Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a miniature bipolar clamp. 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 source, 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] Therefore, the technical problem to be solved by the present invention is that the energy surgical electrode assembly in the prior art is not only complex in structure and difficult to manufacture, but also has low cooling efficiency of the forceps head.

[0005] Therefore, the present invention provides a miniature bipolar clamp, comprising:

[0006] Conductive clamping components;

[0007] A conductive adapter with an internal cavity;

[0008] An insulating element is disposed near the conductive adapter, and the near end of the conductive clamp is hinged to the insulating element; the far end of the conductive clamp and the far end of the conductive adapter are configured to be close to each other to clamp the medium and be electrically connected.

[0009] A piping assembly is connected to the cavity to continuously inject coolant into the cavity.

[0010] A cavity is provided within the conductive adapter, and a piping assembly communicates with the cavity to continuously inject coolant into it. The piping assembly includes an inlet pipe and an outlet pipe arranged in parallel. In use, the inlet pipe continuously delivers coolant into the cavity. The coolant absorbs heat from the conductive adapter and is then discharged through the outlet pipe, thereby cooling the conductive adapter and preventing thermal diffusion damage to adjacent or surrounding tissues due to heat diffusion from the electrodes at the closed position.

[0011] Optionally, the conductive adapter has a placement cavity near its end for placing the insulating component, and a fixing structure for fixing the insulating component is provided between the placement cavity and the insulating component.

[0012] Optionally, the sidewall of the placement cavity is provided with a first placement groove, and the sidewall of the insulating component is provided with a second placement groove. The first placement groove and the second placement groove are aligned to form a placement channel for placing the pipes in the pipe assembly.

[0013] The first placement slot, the second placement slot, and the pipeline in the pipeline assembly constitute the fixed structure.

[0014] The pipes in the pipe assembly will be located inside the channel formed by the first placement slot and the second placement slot. Since the pipes in the pipe assembly are located in the first placement slot and the second placement slot, the fixing structure formed by the pipes in the pipe assembly, the first placement slot and the second placement slot fixes the insulating component, which can prevent the insulating component from falling out of the placement cavity of the conductive adapter.

[0015] Optionally, the conduit assembly has the conduit fixed to the first placement slot, and the insulating element is configured to undergo elastic deformation to enter the placement cavity until the conduit is engaged in the second placement slot.

[0016] Optionally, a through hole suitable for inserting the pipeline assembly is provided between the cavity and the placement cavity, and the pipeline assembly is fixed in the through hole.

[0017] Optionally, the conductive adapter has a snap-fit ​​portion at its proximal end, and the insulating component has a snap-fit ​​adapter portion at its distal end, wherein the snap-fit ​​portion snaps into the snap-fit ​​adapter portion.

[0018] By setting the insulating component to be directly snapped and fixed to the end of the conductive adapter, a larger placement space can be reserved for the insulating component, allowing the insulating component to be made thicker, thus preventing the insulating component from being broken down by the voltage between the conductive clamp and the conductive adapter.

[0019] Optionally, the snap-fit ​​portion includes a through groove penetrating the conductive adapter, and the snap-fit ​​adapter portion is provided with a protrusion suitable for insertion into the through groove.

[0020] By inserting the protrusion into the through groove, the stability of the connection between the insulating component and the conductive adapter can be improved. Since the through groove passes through the snap-fit ​​adapter, after the protrusion is inserted into the groove, the end of the protrusion is located on the bottom side of the conductive adapter. The protrusion and the bottom surface of the conductive adapter can be welded together by welding.

[0021] Optionally, the outer peripheral wall of the insulating component is provided with a mounting groove for installing the pipes in the pipe assembly.

[0022] The installation slots facilitate the installation and fixing of the piping assembly by mounting the piping within it onto the outer wall of the insulating component.

[0023] Optionally, it also includes a fixing pliers head cover, the proximal end of which is annularly sleeved on the proximal end of the insulating member, and the distal end of which is bayoneted and snapped into the snap-fit ​​portion and the snap-fit ​​adapter portion at the snap-fit ​​point.

[0024] The near end of the fixed pliers head cover is fitted onto the surface of the insulating component and fixed, while the far end of the fixed pliers head cover is fixed at the snap-fit ​​point between the snap-fit ​​part and the snap-fit ​​adapter part. By setting the fixed pliers head cover, the conductive adapter can act as a conductor, and the pulling action of the fixed pliers head cover on the insulating component can also prevent the conductive adapter and the insulating component from bending at the connection point.

[0025] Optionally, the distal end of the clamp head cover is provided with a reinforcing groove, which connects to the snap-fit ​​portion and is suitable for being filled with a fixing medium. The fixing medium is used for welding to the surface of the conductive adapter through this reinforcing groove. This arrangement increases the welding area between the clamp head cover and the conductive adapter, improving the stability of the weld.

[0026] The miniature bipolar clamp provided by this invention has the following advantages:

[0027] 1. This invention provides a miniature bipolar clamp, comprising a conductive clamping member, a conductive adapter, an insulating member, and a conduit assembly. The conductive adapter has a cavity, and the insulating member is disposed at the proximal end of the conductive adapter, with the proximal end of the conductive clamping member hinged to the insulating member. The distal end of the conductive clamping member and the distal end of the conductive adapter are configured to be close to each other to clamp a medium and be electrically connected. The conduit assembly is connected to the cavity to continuously inject coolant into the cavity.

[0028] This miniature bipolar clamp features a cavity within the conductive adapter, into which a tubing assembly continuously injects coolant. The tubing assembly includes parallel inlet and outlet pipes. During use, the inlet pipe continuously supplies coolant into the cavity. The coolant absorbs heat from the conductive adapter and is then discharged through the outlet pipe, thus cooling the conductive adapter and preventing thermal diffusion damage to adjacent or surrounding tissues due to heat diffusion from the electrodes at the closed position.

[0029] 2. This invention provides a miniature bipolar clamp, wherein the conductive adapter has a placement cavity for placing the insulating component near its proximal end, and a fixing structure for fixing the insulating component is provided between the placement cavity and the insulating component. The sidewall of the placement cavity has a first placement groove, and the sidewall of the insulating component has a second placement groove. The first placement groove and the second placement groove are aligned to form a placement channel for placing the tubing in the tubing assembly.

[0030] In this miniature bipolar clamp structure, the tubing in the tubing assembly is located inside the channel formed by the first placement slot and the second placement slot. Since the tubing in the tubing assembly is located in the first placement slot and the second placement slot, the fixing structure formed by the tubing in the tubing assembly, the first placement slot and the second placement slot fixes the insulating component, which can prevent the insulating component from falling out of the placement cavity of the conductive adapter.

[0031] 3. The present invention provides a miniature bipolar clamp, wherein the conductive adapter has a snap-fit ​​part at its proximal end and the insulating member has a snap-fit ​​adapter part at its distal end, and the snap-fit ​​part snaps into the snap-fit ​​adapter part.

[0032] This miniature bipolar clamp structure features an insulating component that is directly snapped into and fixed to the end of the conductive adapter. This allows for more space to be reserved for the insulating component, enabling it to be made thicker and preventing voltage breakdown between the conductive clamp and the conductive adapter.

[0033] 4. The present invention provides a miniature bipolar clamp, wherein the snap-fit ​​portion includes a through groove penetrating the conductive adapter, and the snap-fit ​​adapter portion is provided with a protrusion suitable for insertion into the through groove.

[0034] This miniature bipolar clamp structure improves the stability of the connection between the insulating component and the conductive adapter by inserting the protrusion into the through groove. Since the through groove passes through the snap-fit ​​adapter, the end of the protrusion is located on the bottom side of the conductive adapter after it is inserted into the groove. The protrusion can be welded to the bottom surface of the conductive adapter as a whole by welding.

[0035] 5. This invention provides a miniature bipolar clamp that uses a mounting slot to install the tubing in the tubing assembly onto the outer wall of the insulating component, facilitating the installation and fixing of the tubing assembly.

[0036] 6. The present invention provides a miniature bipolar clamp, which further includes a fixed clamp head cover. The proximal end of the fixed clamp head cover is annularly sleeved on the proximal end of the insulating member, and the distal end of the fixed clamp head cover is bayoneted and snapped into the snap-fit ​​portion and the snap-fit ​​adapter portion at the snap-fit ​​point.

[0037] This miniature bipolar clamp has a fixed clamp head cover that is fitted onto and fixed to the surface of the insulating component at its near end, and fixed to the locking part and the locking adapter part at its far end. By setting the fixed clamp head cover, the conductive adapter can act as a wire, and the pulling action of the fixed clamp head cover on the insulating component can also prevent the conductive adapter and the insulating component from bending at the connection point.

[0038] 7. The present invention provides a miniature bipolar clamp, wherein the distal end of the clamp head cover is provided with a reinforcing groove, the reinforcing groove is connected to the snap-fit ​​portion and the reinforcing groove is suitable for filling with a fixing medium.

[0039] In this miniature bipolar clamp structure, the fixing medium is welded to the surface of the conductive adapter through this reinforcing groove. This placement can increase the welding area between the clamp head cover and the conductive adapter, and improve the stability of the weld. Attached Figure Description

[0054] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, 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 effort are within the scope of protection of the present invention.

[0055] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

In addition, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0056] In this embodiment, for ease of explanation, the end closer to the operator is defined as the proximal end, and the end farther from the operator is defined as the distal end.

[0057] Example 1

[0058] This embodiment provides a miniature bipolar clamp, such as Figures 1 to 3 As shown, it includes a conductive clamp 1, a conductive adapter 2, an insulating component 3, and a pipeline assembly 4.

[0059] In this embodiment, as Figure 1 As shown, the insulating element 3 is located near the conductive adapter 2, and the near end of the conductive clamping element 1 is hinged to the insulating element 3. In use, the distal end of the conductive clamping element 1 and the distal end of the conductive adapter 2 are configured to be close together to clamp the medium and be electrically connected. The medium refers to human tissue or blood vessels. This process is a routine operation in electrosurgery, so its principle and specific operation method will not be described in detail here.

[0060] To avoid thermal diffusion damage to adjacent or surrounding tissues due to thermal diffusion of the electrode at the closed position, a cavity is provided inside the distal end of the conductive adapter 2 in this embodiment, and the pipeline assembly 4 is connected to the cavity to continuously inject coolant into the cavity.

[0061] As one implementation method, such as Figure 2 and Figure 3 As shown, the pipeline assembly 4 includes an inlet pipe and an outlet pipe arranged in parallel. In use, the inlet pipe continuously delivers coolant into the cavity. The coolant absorbs heat from the conductive adapter 2 and is then discharged through the outlet pipe to cool the conductive adapter 2 and prevent thermal diffusion damage to adjacent or surrounding tissues due to thermal diffusion of the electrode at the closed position.

[0062] In this embodiment, as Figure 2 As shown, in order to facilitate the fixing of the pipeline assembly 4 after it is inserted into the cavity, the part of the conductive adapter 2 located on the upper side of the cavity is designed to be detachable. That is, during installation, the plate-shaped part on the upper side of the cavity is disassembled, the pipeline assembly 4 is inserted into the cavity and fixed to the conductive adapter 2, and then the plate-shaped part is fixed to the upper side of the cavity by welding or bonding and the connection is sealed. This completes the installation and fixing of the pipeline assembly 4 in the cavity.

[0063] In this embodiment, in order to install and fix the insulating component 3, a placement cavity for placing the insulating component 3 is provided near the conductive adapter 2. For example... Figure 2 and Figure 3 As shown, the upper end of the placement cavity is open, and the insulating component 3 is inserted into the placement cavity through this opening during installation.

[0064] In this embodiment, a fixing structure for fixing the insulating member 3 is provided between the placement cavity and the insulating member 3.

[0065] In one embodiment, the fixing structure consists of two first placement slots 21 formed on the side wall of the placement cavity, two second placement slots 31 formed on the side wall of the insulating member 3, and pipelines (inlet pipe and outlet pipe) in the pipeline assembly 4. The first placement slots 21 and the second placement slots 31 are aligned to form a placement channel for the pipelines in the pipeline assembly 4.

[0066] like Figure 2 and Figure 3As shown, during installation, the inlet pipe and outlet pipe of the pipeline assembly 4 are respectively installed in two first placement grooves 21. The first placement groove 21 is an arc-shaped groove, that is, when the inlet pipe and outlet pipe are installed in the first placement groove 21, part of the side wall of the inlet pipe and outlet pipe protrudes from the side wall surface of the placement cavity. In this embodiment, the insulating component 3 can undergo elastic deformation when subjected to force. Therefore, when the insulating component 3 is inserted into the placement cavity of the conductive adapter 2, the two sides of the insulating component 3 are squeezed by the side walls of the inlet pipe and outlet pipe and undergo elastic deformation until the insulating component 3 is fully installed. After that, the part of the inlet pipe and outlet pipe protruding from the side wall surface of the placement cavity enters the second placement groove 31 on both sides of the insulating component 3, and the insulating component 3 recovers its deformation.

[0067] It is understood that after the above installation is completed, the pipes in the pipe assembly 4 will be located inside the channel formed by the first placement groove 21 and the second placement groove 31. Since the pipes in the pipe assembly 4 are located in the first placement groove 21 and the second placement groove 31, the fixing structure formed by the pipes in the pipe assembly 4, the first placement groove 21, and the second placement groove 31 fixes the insulating component 3, preventing the insulating component 3 from falling out of the placement cavity of the conductive adapter 2. In order to fix the insulating component 3 through the pipes in the pipe assembly 4, the pipes need to have a certain rigidity to prevent deformation and loss of restraint on the insulating component 3. The pipes can be made of metal.

[0068] Furthermore, in order to further improve the stability of the insulating component 3 inside the placement cavity on the conductive adapter 2, liquid adhesive can be dripped into the gap between the insulating component 3 and the placement cavity after the insulating component 3 enters the placement cavity.

[0069] Furthermore, such as Figure 1 and Figure 2 As shown, the upper part of the far end of the insulating component 3 is provided with a protruding part, and the far end of the conductive adapter 2 is provided with a stepped structure accordingly. After the insulating component 3 is installed inside the placement groove of the conductive adapter 2, the protruding part on the insulating component 3 abuts against the stepped structure at the far end of the conductive adapter 2.

[0070] In this embodiment, a through hole suitable for inserting the pipeline assembly 4 is provided between the cavity and the placement cavity, and the pipeline assembly 4 is fixed in the through hole.

[0071] In this embodiment, a placement cavity for placing the insulating component 3 is provided near the conductive adapter 2, and a first placement groove 21 is provided on the side wall of the placement cavity, and a second placement groove 31 is provided on the side wall of the insulating component 3. The first placement groove 21 and the second placement groove 31 are aligned to form a placement channel for the pipeline in the pipeline assembly 4. Thus, the pipeline in the pipeline assembly 4 can not only inject coolant into the cavity at the far end of the conductive adapter 2 to cool the conductive adapter 2, but also fix the insulating component 3 through this pipeline.

[0072] The miniature bipolar forceps provided in this embodiment are used in minimally invasive surgery. Under the premise of ensuring that the diameter of the forceps head is adapted to the trocar, the insulating component 3 is integrated into the placement cavity at the proximal end of the conductive adapter 2. This not only fixes the insulating component 3 in the placement cavity through the fixing structure, but also provides the insulating component 3 with the largest possible placement space to increase the thickness of the insulating component 3 and prevent it from being broken down by voltage.

[0073] Example 2

[0074] This embodiment provides a miniature bipolar clamp, which differs from the miniature bipolar clamp provided in Embodiment 1 in that:

[0075] In this embodiment, as Figures 4 to 6 As shown, the near end of the conductive adapter 2 is snapped into the far end of the insulating component 3, and the conductive adapter 2 and the insulating component 3 are further fixed by a fixing clamp head cover 5.

[0076] In a specific implementation, the conductive adapter 2 has a snap-fit ​​part 22 at its near end, and the insulating member 3 has a snap-fit ​​adapter part 32 at its far end, and the snap-fit ​​part 22 snaps into the snap-fit ​​adapter part 32.

[0077] like Figure 5 As shown, the snap-fit ​​part 22 includes a through groove that penetrates the conductive adapter 2, and the snap-fit ​​adapter part 32 is provided with a protrusion suitable for insertion into the through groove.

[0078] During installation, insert the protrusion on the snap-fit ​​adapter 32 into the through groove on the snap-fit ​​part 22, and inject liquid adhesive at the contact points between the protrusion and the through groove to fix the two together.

[0079] The purpose of setting the through groove and the protrusion in this embodiment is to improve the stability of the connection between the insulating part 3 and the conductive adapter 2 by inserting the protrusion into the through groove. Since the through groove passes through the snap-fit ​​adapter part 32, after the protrusion is inserted into the groove, the end of the protrusion is located on the bottom side of the conductive adapter 2. The protrusion and the bottom surface of the conductive adapter 2 can be welded together by welding.

[0080] In this embodiment, as Figure 5 As shown, the near end of the fixing pliers head cover 5 is annular, and the far end of the fixing pliers head cover 5 is bayoneted, that is, the far end of the fixing pliers head cover 5 has an upward-opening bayonet mouth. During assembly, the near end of the fixing pliers head cover 5 is annularly fitted onto the near end of the insulating part 3, and the far end of the fixing pliers head cover 5 is bayoneted into the bayonet joint of the snap-fit ​​part 22 and the snap-fit ​​adapter part 32.

[0081] During installation, the fixing plier head cover 5 is sleeved on the surface of the insulating part 3 through the far end of the insulating part 3, and then the near end of the fixing plier head cover 5 is fixed to the surface of the insulating part 3 with glue. At this time, the near end of the fixing plier head cover 5 is engaged at the engagement point of the engagement part 22 and the engagement adapter part 32. The near end of the fixing plier head cover 5 is welded to the surface of the conductive adapter 2 by welding.

[0082] In this embodiment, a snap-fit ​​part 22 is provided at the near end of the conductive adapter 2, and a snap-fit ​​adapter part 32 is provided at the far end of the insulating member 3. The snap-fit ​​part 22 and the snap-fit ​​adapter part 32 snap together to fix the conductive adapter 2 and the insulating member 3. Then, a fixing pliers head cover 5 is fitted onto the insulating member 3. The near end of the fixing pliers head cover 5 is fitted onto the surface of the insulating member 3 and fixed, and the far end of the fixing pliers head cover 5 is fixed at the snap-fit ​​point between the snap-fit ​​part 22 and the snap-fit ​​adapter part 32. By setting the fixing pliers head cover 5, the conductive adapter 2 can act as a conductor, and the pulling action of the fixing pliers head cover 5 on the insulating member 3 can also prevent the conductive adapter 2 and the insulating member 3 from bending at the connection point.

[0083] Furthermore, to improve the stability of the connection between the fixing clamp head cover 5 and the conductive adapter 2, such as... Figure 6 As shown, the distal end of the fixing clamp head cover 5 is provided with a reinforcing groove 6, which connects to the snap-fit ​​part 22 and is suitable for being filled with a fixing medium. Specifically, the fixing medium is welded to the surface of the conductive adapter 2 through this reinforcing groove 6. This arrangement can increase the welding area between the fixing clamp head cover 5 and the conductive adapter 2 and improve the stability of the weld.

[0084] In this embodiment, as Figure 5 As shown, the outer wall of the insulating component 3 is provided with a mounting groove for installing the pipes in the pipe assembly 4.

[0085] The miniature bipolar forceps provided in this embodiment uses a mounting groove to install the tubing in the tubing assembly 4 onto the outer wall of the insulating component 3, facilitating the installation and fixation of the tubing assembly 4. Simultaneously, the direct snap-fit ​​fixing of the insulating component 3 to the end of the conductive adapter 2 allows for more space to be provided for the insulating component 3, enabling it to be made thicker and preventing voltage breakdown between the conductive clamping component 1 and the conductive adapter 2. Furthermore, the direct snap-fit ​​fixing of the insulating component 3 to the conductive adapter 2 ensures that the forceps head diameter meets the requirements of minimally invasive surgery, facilitating the use of trocars in minimally invasive procedures.

[0086] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
