Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a multimodal surgical electrode for use in the abdominal cavity. Background Technology

[0002] In abdominal surgery, different instruments are typically used for tissue cutting and vascular coagulation. Monopolar electrocoagulation hooks are mainly used to cut lining tissues such as the mesentery, viscera, etc. However, when encountering vascular tissue, bipolar electrocoagulation forceps are needed to coagulate the blood vessels before cutting. Currently, the monopolar electrocoagulation hook and bipolar electrocoagulation forceps are two separate instruments. Switching between them requires removing the former from the abdominal cavity and inserting the latter, which is cumbersome and increases surgical time and risk. Utility Model Content

[0003] The objectives of this invention include, for example, providing a multimodal surgical electrode for the abdominal cavity that can reduce the difficulty of switching between different instruments during surgery, shorten the time, improve surgical efficiency, reduce the risk of infection, and increase the success rate of surgery.

[0004] The embodiments of this utility model can be implemented as follows:

[0005] In a first aspect, this utility model provides a multimodal surgical electrode for use in the abdominal cavity, comprising:

[0006] The device includes an operating handle, a sheath, a cable, a bipolar electrocautery clamp assembly, and a monopolar electrocautery hook. The sheath is connected to the operating handle, which is connected to the bipolar electrocautery clamp assembly via the cable, for controlling the opening or closing of the bipolar electrocautery clamp. At least one of the bipolar electrocautery clamp assembly and the monopolar electrocautery hook slides into the sheath, allowing either the monopolar electrocautery hook or the bipolar electrocautery clamp assembly to extend beyond the distal end of the sheath and operate independently.

[0007] In an optional embodiment, the monopolar electrocautery hook is fixedly connected to the sheath and extends beyond the distal end of the sheath; the bipolar electrocautery clamp assembly is slidably engaged with the sheath, and the bipolar electrocautery clamp assembly has a first position and a second position that can be switched between each other. In the first position, the bipolar electrocautery clamp assembly is located outside the distal end of the sheath, and the monopolar electrocautery hook is attached to the outside of the bipolar electrocautery clamp assembly; in the second position, the bipolar electrocautery clamp assembly is retracted into the sheath.

[0008] Based on the above scheme, the monopolar electrocoagulation hook is set to a fixed type, and the bipolar electrocoagulation clamp assembly is set to a sliding type. By controlling the position of the bipolar electrocoagulation clamp assembly, the bipolar electrocoagulation clamp assembly or the monopolar electrocoagulation hook can be used independently, which is convenient for operation.

[0009] In an optional embodiment, a fixing ring is provided inside the sheath, the bipolar electrocoagulation clamp assembly passes through the fixing ring and is slidably engaged with the fixing ring, and the unipolar electrocoagulation hook is fixed on the fixing ring.

[0010] Based on the above scheme, the unipolar electrocoagulation hook is installed on the fixing ring for easy fixation.

[0011] In an optional embodiment, the bipolar electrocoagulation clamp assembly includes a first clamp arm and a second clamp arm, the first clamp arm and the second clamp arm being rotatably connected, the first clamp arm being slidably engaged with the sheath, and the second clamp arm being connected to the cable, the cable being used to drive the second clamp arm to rotate relative to the first clamp arm; when the bipolar electrocoagulation clamp assembly is in the first position, the unipolar electrocoagulation hook is located on the side of the first clamp arm away from the second clamp arm.

[0012] Based on the above scheme, by pulling the cable, the second clamp arm can be rotated relative to the first clamp arm, thereby adjusting the angle of the second clamp arm relative to the first clamp arm, realizing the opening or closing of the bipolar electrocoagulation clamp assembly, which is simple and flexible to operate.

[0013] In an optional embodiment, a receiving groove is provided on the side of the first clamp arm away from the second clamp arm, and when the bipolar electrocoagulation clamp assembly is in the first position, the unipolar electrocoagulation hook is located in the receiving groove.

[0014] Based on the above scheme, when the bipolar electrocoagulation forceps assembly is needed, the assembly extends out of the sheath, and the monopolar electrocoagulation hook can be actively retracted into the receiving groove. The monopolar electrocoagulation hook and the second clamp arm are located on opposite sides of the first clamp arm. The monopolar electrocoagulation hook does not easily affect the rotation of the second clamp arm relative to the first clamp arm, nor does it easily affect the cooperation between the first and second clamp arms in clamping the tissue. Furthermore, the monopolar electrocoagulation hook, located in the receiving groove, is tightly integrated with the first clamp arm, has a small size, and is unlikely to interfere with the tissue.

[0015] In an optional embodiment, the bipolar electrocoagulation clamp assembly further includes a conductive tube and an insulating tube. The conductive tube is connected to the first clamp arm and is slidably engaged with the sheath. The insulating tube passes through the conductive tube, and the pull cable passes through the insulating tube and is slidably engaged with the insulating tube. The unipolar electrocoagulation hook is electrically connected to the conductive tube.

[0016] Based on the above solution, by using a combination of conductive and insulating tubes, it is possible to connect the first clamp arm to the operating handle, while also ensuring that the cable is isolated from the conductive tube. When energized, the cable and conductive tube will not come into direct contact, making it less likely to short circuit and improving safety.

[0017] In an optional embodiment, the bipolar electrocautery clamp assembly further includes a drive unit mounted on the operating handle and connected to the conductive tube for driving the conductive tube to slide relative to the sheath.

[0018] Based on the above scheme, by driving the conductive tube to slide relative to the sheath tube through the driving unit, the first clamp arm and the second clamp arm can slide together relative to the sheath tube, which is convenient to operate.

[0019] In an optional embodiment, the drive unit includes a drive wheel and a drive cylinder. The drive wheel is rotatably connected to the operating handle, and a first tooth is provided on the outer circumferential surface of the drive wheel. The drive cylinder is slidably engaged with the operating handle, and a second tooth is provided on the outer circumferential wall of the drive cylinder, with the first tooth meshing with the tooth. The drive cylinder is connected to the conductive tube. When the drive wheel is rotated, the drive cylinder drives the first clamp arm and the second clamp arm to slide relative to the sheath tube through the conductive tube.

[0020] Based on the above scheme, by turning the drive wheel, the first toothed body transmits external force to the second toothed body, thereby driving the drive cylinder to slide, and then driving the conductive tube to slide. The operation is convenient, and the first and second toothed bodies mesh together, which has a self-locking function and a stable and reliable cooperation.

[0021] In an optional embodiment, the second tooth is configured as an annular structure surrounding the axis of the drive cylinder.

[0022] Based on the above solution, the second tooth has a wide coverage area, and when installing the drive cylinder, there is no need to consider the relative position of the drive cylinder and the conductive tube in the circumferential direction, making installation convenient and quick. Furthermore, even if the conductive tube drives the first and second clamping arms to rotate and adjust the clamping angle, the first and second teeth can always be in a meshing state, thereby driving the drive cylinder to slide through the drive wheel.

[0023] In an optional embodiment, the operating handle includes a first handle, a second handle, and a knob. The sheath is mounted on the first handle, the second handle is rotatably engaged with the first handle, and the cable is mounted on the second handle. When the second handle rotates relative to the first handle, the cable slides relative to the conductive tube, thereby driving the second clamp arm to rotate relative to the first clamp arm. The knob is rotatably mounted on the first handle, the conductive tube passes through the knob, and the conductive tube and the knob are slidably engaged in the axial direction of the conductive tube. The conductive tube and the knob are relatively fixed relative to each other in the circumferential direction of the knob.

[0024] Based on the above scheme, the cable control is convenient and quick. Furthermore, by rotating the knob, the positions of the first and second clamping arms in the circumferential direction of the sheath can be adjusted, thus regulating the clamping angle and providing a wide range of adaptability.

[0025] The beneficial effects of this utility model embodiment include, for example:

[0026] In summary, the multimodal surgical electrode for subperitoneal surgery provided in this embodiment combines a bipolar electrocoagulation forceps assembly and a monopolar electrocoagulation hook. During surgery, the relative positions of the bipolar electrocoagulation forceps assembly and the monopolar electrocoagulation hook can be adjusted as needed, thereby achieving independent operation of the bipolar electrocoagulation forceps assembly and the monopolar electrocoagulation hook. Furthermore, the switching action between the bipolar electrocoagulation forceps assembly and the monopolar electrocoagulation hook can be performed directly within the abdominal cavity, without the need for repeated entry and exit. This allows for rapid switching within the abdominal cavity, is convenient and time-saving, improves surgical efficiency, reduces the probability of cross-infection, and enhances surgical safety.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model 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 this utility model.

[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0043] In current technology, several different surgical instruments are generally used during abdominal surgery to meet the needs of different stages or types of surgery. Currently, each surgical instrument has a single function and can basically only perform one type of surgery. For example, when tissue removal or cutting is required, bipolar forceps and monopolar hooks are needed respectively. Both surgical instruments need to be removed from the abdominal cavity and inserted separately, which is cumbersome, time-consuming, and increases surgical risks.

[0044] In view of this, the designers have provided a multimodal surgical electrode for the abdominal cavity, which can switch between different surgical instruments in the abdominal cavity. It is convenient to operate, saves time and effort, is highly efficient, reduces surgical risks, and improves the success rate of surgery.

[0045] Please refer to Figures 1-7 This embodiment provides a multimodal surgical electrode for subabdominal surgery, which includes an operating handle 100, a sheath 200, a cable 300, a bipolar electrocoagulation forceps assembly 400, and a monopolar electrocoagulation hook 500. The sheath 200 is connected to the operating handle 100, and the operating handle 100 is connected to the bipolar electrocoagulation forceps assembly 400 via the cable 300 for controlling the opening or closing of the bipolar electrocoagulation forceps. At least one of the bipolar electrocoagulation forceps assembly 400 and the monopolar electrocoagulation hook 500 is slidably engaged with the sheath 200 so that either the monopolar electrocoagulation hook 500 or the bipolar electrocoagulation forceps assembly 400 can extend to the distal end of the sheath 200 and operate independently.

[0046] As described above, the working principle of the subabdominal multimodal surgical electrode provided in this embodiment is as follows:

[0047] During the procedure, the positions of the bipolar electrocoagulation forceps assembly 400 and the monopolar electrocoagulation hook 500 relative to the sheath 200 can be adjusted as needed, changing their relative positions and allowing them to operate independently. When using the bipolar electrocoagulation forceps assembly 400 alone, force can be applied to the operating handle 100, using the cable 300 to move the assembly, switching it from an open to a closed state for tasks such as clamping and removing coagulated tissue. Then, the bipolar electrocoagulation forceps assembly 400 and the monopolar electrocoagulation hook 500 can be readjusted to allow the monopolar electrocoagulation hook 500 to operate independently for tasks such as tissue cutting. Since the switching action between the bipolar electrocoagulation forceps assembly 400 and the monopolar electrocoagulation hook 500 can be performed directly in the abdominal cavity without repeatedly entering and exiting the abdominal cavity, the switching can be completed quickly within the abdominal cavity. The switching is convenient and time-saving, which can improve surgical efficiency, reduce the probability of surgical cross-infection, and improve surgical safety.

[0048] The details of the subabdominal multimodal surgical electrode according to embodiments of this application are described by way of example.

[0049] Please refer to Figures 1-4 In this embodiment, optionally, the operating handle 100 includes a first handle 110, a second handle 120, a knob 130, and a conductive connector 140. The sheath 200 is installed at the distal end of the first handle 110. The second handle 120 is rotatably engaged with the first handle 110. The two can be connected by a torsion spring. The torsion spring causes the first handle 110 and the second handle 120 to always tend to move away from each other. That is, in the initial state, the first handle 110 and the second handle 120 are open. When in use, force is applied to them, and the second handle 120 can rotate closer to the first handle 110. When released, the second handle 120 returns to its original position under the action of the torsion spring. Meanwhile, the top of the first handle 110 is provided with a sliding channel 111 and an assembly hole 112 communicating with the sliding channel 111. The conductive connector 140 is slidably installed in the sliding channel 111, and the pull cable 300 is fixed in the conductive connector 140. The pull cable 300 and the conductive connector 140 are electrically connected. Specifically, the conductive connector 140 has a positive terminal and a negative terminal, and the pull cable 300 is connected to the negative terminal of the conductive connector 140. The second handle 120 and the conductive connector 140 can be connected by a ball joint 150. When the second handle 120 rotates relative to the first handle 110, it can drive the pull cable 300 to move the bipolar electrocautery clamp assembly 400 through the conductive connector 140, thereby realizing the switching of the working state of the bipolar electrocautery clamp assembly 400. The knob 130 is rotatably mounted on the first handle 110. The knob 130 is in transmission cooperation with the bipolar electrocoagulation clamp assembly 400 and the unipolar electrocoagulation hook 500. When the knob 130 is rotated, it can drive the two to rotate synchronously around the axis of the sheath tube 200, thereby adjusting the working direction.

[0050] It should be understood that a through hole can be provided near the distal end of the first handle 110, and the knob 130 is rotatably mounted in the through hole. The knob 130 is fixed relative to the first handle 110 in the extension direction of the sheath 200, that is, the knob 130 can only rotate relative to the first handle 110 and will not slide relative to the first handle 110. The rear end of the sheath 200 is fixed to the distal end of the first handle 110, and the sheath 200 does not extend into the through hole, so it will not affect the engagement of the knob 130 with the bipolar electrocautery pliers assembly 400 and the unipolar electrocautery hook 500.

[0051] In this embodiment, optionally, the monopolar electrocoagulation hook 500 is fixedly connected to the sheath 200 and extends beyond the distal end of the sheath 200; the bipolar electrocoagulation clamp assembly 400 is slidably engaged with the sheath 200, and the bipolar electrocoagulation clamp assembly 400 has a first position and a second position that can be switched between each other. When in the first position, the bipolar electrocoagulation clamp assembly 400 is located outside the distal end of the sheath 200, and the monopolar electrocoagulation hook 500 is attached to the outside of the bipolar electrocoagulation clamp assembly 400; when in the second position, the bipolar electrocoagulation clamp assembly 400 is retracted into the sheath 200.

[0052] Please refer to Figures 3-5 For ease of installation, a retaining ring 600 is provided inside the sheath 200. The retaining ring 600 is circular and rotatably engages with the sheath 200, but the two are relatively fixed in the extending direction of the sheath 200. The rear end of the monopolar coagulation hook 500 is fixed to the retaining ring 600, so the monopolar coagulation hook 500 will not slide relative to the sheath 200, and the position of the monopolar coagulation hook 500 extending out of the sheath 200 will not change. The bipolar coagulation clamp assembly 400 passes through the retaining ring 600 and slidably engages with the retaining ring 600. With this design, when the bipolar coagulation clamp assembly 400 needs to be used, it is slid relative to the sheath 200 and engaged with the monopolar coagulation hook 500. At this time, the monopolar coagulation hook 500 is close to the outside of the bipolar coagulation clamp assembly 400, which does not affect the independent use of the bipolar coagulation clamp assembly 400. When the monopolar electrocoagulation hook 500 is needed, operate the bipolar electrocoagulation clamp assembly 400 to retract it into the sheath 200, and the monopolar electrocoagulation hook 500 is exposed outside the sheath 200 and can be used independently.

[0053] Please refer to Figures 5-6 Optionally, the bipolar electrocautery clamp assembly 400 includes a first clamp arm 410 and a second clamp arm 420. The first clamp arm 410 and the second clamp arm 420 are rotatably connected. The first clamp arm 410 is slidably engaged with the sheath tube 200. The second clamp arm 420 is connected to a cable 300, which drives the second clamp arm 420 to rotate relative to the first clamp arm 410, thereby opening or closing the first clamp arm 410 and the second clamp arm 420. When the bipolar electrocautery clamp assembly is in the first position, the unipolar electrocautery hook 500 is located on the side of the first clamp arm 410 away from the second clamp arm 420.

[0054] Furthermore, a receiving groove 411 is provided on the side of the first clamp arm 410 away from the second clamp arm 420. When the bipolar electrocoagulation clamp assembly is in the first position, the monopolar electrocoagulation hook 500 is located in the receiving groove 411. When the bipolar electrocoagulation clamp assembly 400 needs to be used, the bipolar electrocoagulation clamp assembly 400 extends out of the sheath 200, and the monopolar electrocoagulation hook 500 can be actively stored in the receiving groove 411. The monopolar electrocoagulation hook 500 and the second clamp arm 420 are located on opposite sides of the first clamp arm 410. The monopolar electrocoagulation hook 500 does not easily affect the rotation of the second clamp arm 420 relative to the first clamp arm 410, and does not easily affect the cooperation of the first clamp arm 410 and the second clamp arm 420 in clamping tissue. In addition, the monopolar electrocoagulation hook 500 is located in the receiving groove 411, is tightly coupled with the first clamp arm 410, has a small size, and is unlikely to interfere with tissue.

[0055] Please refer to Figures 3-4 Optionally, the bipolar electrocautery clamp assembly 400 further includes a conductive tube 430 and an insulating tube 440. The distal end of the conductive tube 430 is connected to the rear end of the first clamp arm 410. The conductive tube 430 is located inside the sheath 200 and slidably engages with the sheath 200. The conductive tube 430 passes through a fixing ring 600, which is a metal ring, and the two are electrically connected. The conductive tube 430 also passes through a knob 130, and the conductive tube 430 and the knob 130 are slidably engaged axially in the conductive tube 430 and fixed relative to each other circumferentially in the knob 130. The insulating tube 440 passes inside the conductive tube 430, and the two can be fixed by adhesive bonding or thermoplastic bonding. A pull cable 300 passes inside the insulating tube 440, and the pull cable 300 is slidably engaged with the insulating tube 440. The single-pole electrocoagulation hook 500 is fixed to the fixing ring 600, and is electrically connected to the conductive tube 430 through the fixing ring 600. The conductive tube 430 passes through the sliding channel 111 and is slidably connected to the conductive connector 140, with the positive electrode of the conductive tube 430 electrically connected to the conductive connector 140. It should be understood that the positive electrode plate inside the conductive connector 140 can be annular and has a certain length to ensure that the conductive tube 430 and the conductive connector 140 are always in electrical contact when the conductive tube 430 slides relative to the conductive connector 140. Through the cooperation of the conductive tube 430 and the insulating tube 440, the connection between the first clamp arm 410 and the operating handle 100 can be realized, and the cable 300 can be isolated from the conductive tube 430. When energized, the cable 300 and the conductive tube 430 will not directly contact each other, which reduces the risk of short circuit and improves safety.

[0056] Please refer to Figure 7 Furthermore, the bipolar electrocautery clamp assembly also includes a drive unit, which is mounted on the operating handle 100 and connected to the conductive tube 430, for driving the conductive tube 430 to slide relative to the sheath 200 and the conductive connector 140.

[0057] Optionally, the drive unit includes a drive wheel 450 and a drive cylinder 460. The drive wheel 450 is rotatably connected to the mounting hole 112 of the operating handle 100 via a rotating shaft 470. Multiple first teeth 451 are provided on the outer circumferential surface of the drive wheel 450, and these teeth are evenly spaced around the axis of the drive wheel 450. The drive cylinder 460 is slidably engaged with the sliding channel 111 of the operating handle 100. Multiple second teeth 461 are provided on the outer circumferential wall of the drive cylinder 460, and these teeth are evenly spaced along the axial extension direction of the drive cylinder 460. The first teeth 451 mesh with these teeth. The drive cylinder 460 is sleeved around the conductive tube 430, and the two are fixedly connected. When the drive wheel 450 is rotated, it drives the drive cylinder 460 to move linearly. The drive cylinder 460 drives the first clamp arm 410 and the second clamp arm 420 to slide relative to the sheath tube 200 through the conductive tube 430, thereby enabling the first clamp arm 410 and the second clamp arm 420 to retract or extend from the distal end of the sheath tube 200.

[0058] Furthermore, the drive wheel 450 and the first handle 110 can be connected via a damping layer, making it difficult for the drive wheel 450 to rotate automatically relative to the first handle 110. Also, when controlling the relative rotation of the first handle 110 and the second handle 120, the drive cylinder 460 is unlikely to drive the drive wheel 450, ensuring the normal engagement or disengagement of the first clamp arm 410 and the second clamp arm 420. Alternatively, to prevent the conductive tube 430 from slipping when force is applied to the first handle 110 and the second handle 120, external force can be used to intervene in the drive wheel 450 to prevent its rotation.

[0059] Furthermore, the second tooth 461 is configured as an annular structure surrounding the axis of the drive cylinder 460. The second tooth 461 has a wide coverage area, and when installing the drive cylinder 460, there is no need to consider the relative circumferential position of the drive cylinder 460 and the conductive tube 430, making installation convenient and quick. Moreover, even when the knob 130 rotates to adjust the clamping angle by driving the first clamping arm 410 and the second clamping arm 420 via the conductive tube 430, the first tooth 451 and the second tooth 461 remain in a meshing state, thereby driving the drive cylinder 460 to slide via the drive wheel 450.

[0060] It should be noted that, in order to reduce the wiring harness, the subabdominal multimodal surgical electrode also includes an integrated power supply cable assembly 700. The integrated power supply cable assembly 700 includes a first electrical plug 710, a second electrical plug 720, a busbar circuit board 730, and a third electrical plug 740. The first electrical plug 710 has a positive electrode and a negative electrode, and the second electrical plug 720 has a positive electrode. Both the first electrical plug 710 and the second electrical plug 720 are electrically connected to the busbar circuit board 730, so that the positive electrode of the second electrical plug 720 is integrated with the positive electrode of the first electrical plug 710. A positive terminal and a negative terminal are led out from the busbar circuit board 730, and both the positive terminal and the negative terminal are electrically connected to the third electrical plug 740. The third electrical plug 740 is plugged into a conductive connector 140, with the positive terminal of the third electrical plug 740 connected to the positive terminal of the conductive connector 140, and the negative terminal of the third electrical plug 740 connected to the negative terminal of the conductive connector 140. Thus, the busbar circuit board 730 and the third electrical plug 740 can be connected via positive and negative wires, which can be covered by an insulating tube 440, resulting in fewer wires and a lower probability of them interfering with the surgical procedure. In use, both the first electrical plug 710 and the second electrical plug 720 are electrically connected to the entire device. The first clamp arm 410 and the unipolar electrocautery hook 500 are connected to the positive terminal, and the second clamp arm 420 is connected to the negative terminal.

[0061] It should be understood that in other embodiments, the bipolar electrocoagulation clamp assembly 400 and the unipolar electrocoagulation hook 500 can also be powered by other means, such as being powered independently, etc., which will not be described in detail in this embodiment.

[0062] In this embodiment, the structural design of the sub-abdominal multimodal surgical electrode enables efficient and safe switching between the bipolar electrocoagulation forceps assembly 400 and the monopolar electrocoagulation hook 500 within the abdominal cavity. This facilitates quick and easy operation, increases efficiency, shortens surgical time, and reduces surgical risks.

[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
