Description

Technical Field

[0001] This invention relates to an active surgical instrument, a mold for manufacturing a jaw assembly of an active surgical instrument, and a method for manufacturing a jaw assembly of an active surgical instrument. Background Technology

[0002] Active surgical instruments refer to surgical instruments that possess energy sources such as electricity, light, heat, sound, and vibration, such as electrosurgical units and laser scalpels. These instruments can provide energy to cut, remove, or coagulate the patient's tissues and organs, but they also carry certain risks. The use of these instruments requires professional training and adherence to standardized surgical procedures; otherwise, it may adversely affect the patient's health.

[0003] Active surgical instruments, such as active surgical forceps used in minimally invasive surgery, require wires to connect the jaws. To prevent the wires from protruding and interfering with the surgical procedure or touching other tissues, the wires need to be tightly fitted within a wire groove. As the jaws move, the wires also rotate within this groove. If an injection molding process is used, the wires are injected into the plastic, which can cause the bending radius to be too large, resulting in most of the wire protruding from its tip. During insertion into the body and the procedure, this protruding wire can constantly rub against adjacent tissues, affecting the surgeon's operation.

[0004] Furthermore, since the specifications of the wires cannot be changed (meaning that thinner wires or thinner insulation cannot be used), excessive bending of the wires can damage the insulation, potentially leading to electrical leakage. Summary of the Invention

[0005] This invention relates to an active surgical instrument having an instrument tip with grippers and two jaw assemblies rotatably supported in the grippers. Each jaw assembly has a wire, a conductive jaw, and an insulating base surrounding a pivot section of the jaw. The wire has a core and an insulating sheath, with the core exposed at one end to form an exposed section. The pivot section of the jaw is electrically fixedly connected to the exposed section of the wire core. The base has a notch at the location where the exposed section is fixedly connected to the jaw, with the exposed section of the wire located within the notch. The end of the insulating sheath of the wire is movable relative to the base.

[0006] In one embodiment, the exposed portion of the conductor is insulated and sealed by a sealant.

[0007] In one embodiment, the sealant is designed as a sealant that fills the recess so that it completely surrounds the exposed portion of the wire core.

[0009] In one embodiment, the substrate has a wire groove that extends in an arc shape from the recessed portion.

[0010] In one embodiment, at the limit position when the jaw assembly is open during normal operation, the insulation of the wire is completely against the wire groove.

[0012] In one embodiment, with the two jaw assemblies installed, the wire rope grooves of the two jaw assemblies are located between the two conductor grooves.

[0013] The present invention also relates to a mold for manufacturing a jaw assembly of an active surgical instrument, the mold being used for injection molding an insulating substrate of the jaw assembly, wherein the mold has a fixed mold and a movable mold, wherein the movable mold is movable relative to the fixed mold, wherein a mechanism assembly for clamping a wire of the jaw assembly is provided in the movable mold, wherein the mechanism assembly has a slider groove, a first slider and a second slider, wherein the first slider and the second slider are arranged in the slider groove and movable between a feed position and a retract position, wherein when the first slider and the second slider are mated at the feed position, a channel is formed, the channel being adapted to the wire, and the end of the channel facing the jaw assembly is adapted to the shape of the jaw, such that a notch is formed after the insulating substrate of the jaw assembly is injection molded, and the exposed portion of the wire core is located within the notch, and the end of the wire insulation is movable relative to the substrate.

[0014] In one embodiment, the first slider and the second slider each have a corresponding first hole, in which an elastic element is placed.

[0015] In one embodiment, the first slider and the second slider each have a corresponding second hole, in which a positioning element is placed.

[0016] In one embodiment, the mechanism assembly has a push rod, and the first slider and the second slider each have corresponding grooves for receiving the end of the push rod.

[0017] In one embodiment, the slider groove has a wider groove space at the exit position compared to the feed position, the first slider and the second slider are separated at the exit position, and the first slider and the second slider are connected at the feed position.

[0018] In one implementation, the space inside the tank continuously widens from the feed position to the exit position.

[0019] In one embodiment, the space inside the slot has a constant first width from the feed position and a constant second width at the exit position, the second width being greater than the first width.

[0020] In one embodiment, the end of the channel facing the jaws is composed of a first protruding structure of a first slider and a second protruding structure of a second slider, and the first and second protruding structures constitute a tubular structure, the outer diameter of which corresponds to the inner diameter of the notch.

[0021] The present invention also relates to a method for manufacturing a jaw assembly for an active surgical instrument, wherein the jaw assembly has a wire, a conductive jaw, and an insulating substrate surrounding a pivot section of the jaw, the method comprising the following steps: - Prepare the conductor and clamps, wherein the conductor has a core and insulation, and the core is exposed at the end of the conductor to form an exposed section. - The pivot section of the clamp jaws is electrically and securely connected to the exposed section of the conductor core. - The jaws and exposed sections are injection molded so that the insulating substrate surrounding the pivot section of the jaws is injection molded, and the substrate has a notch at the position where the exposed section is fixedly connected to the jaws, and the exposed section of the conductor is located in the notch, and the end of the conductor insulation is movable relative to the substrate.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below 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 described 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.

[0034] The accompanying drawings in this invention are not drawn to scale. The specific dimensions and quantity of each structure can be determined according to actual needs.

[0035] Reference Figure 1 and Figure 2This invention provides an active surgical instrument 100, which has an instrument end 1 with grippers 4 and two jaw assemblies 2. The two jaw assemblies are rotatably supported in the grippers 4 by jaw pins 5. Each jaw assembly has a wire 3, conductive jaws 9, and an insulating base 11 surrounding a pivot section 12 of the jaws. The wire has a core and an insulating sheath 14, with the core exposed at the end of the wire to form an exposed section 13. The pivot section of the jaws is electrically fixedly connected to the exposed section of the wire core. The base has a notch 15 at the position where the exposed section is fixedly connected to the jaws, and the exposed section of the wire core is located within the notch. The end of the insulating sheath of the wire is movable relative to the base. This ensures that the bending radius of the wire is very small, so that a portion of the wire always rests against the wire groove 17 and does not protrude when the jaws rotate. Therefore, when the jaw assembly enters the human body and during operation, the wire will not rub against adjacent tissues and will not affect the surgeon's operation.

[0036] Figure 1 The left side shows an overall view of the active surgical instrument 100, which has an instrument housing 102, an instrument rod 101 connected thereto, and an instrument end 1. Figure 1 The mid-view shows an exploded view of the instrument tip 1 of an active surgical instrument, wherein the instrument tip has jaws 4 and two jaw assemblies 2. The two jaw assemblies are rotatably supported in the jaws 4 by jaw pins 5. A wire rope guide pulley 6 is rotatably supported on the jaws 4, and the jaws are rotatably supported on a U-shaped seat 8 by a U-shaped seat pin 7. Each jaw assembly has a wire 3, conductive jaws 9, and an insulating base 11 surrounding a pivot section 12 of the jaws. The conductive jaws 9 may be metal, and the insulating base may be plastic, preferably injection-molded plastic. The wire has a core and an insulating sheath, with the core exposed at the end of the wire to form an exposed section. (Refer to...) Figure 1 An independent view of the jaws on the right side, wherein the pivot section 12 of the jaws is electrically fixedly connected to the exposed section 13 of the conductor core 3, preferably by means of riveting, and the unexposed section of the conductor core is covered by insulation 14.

[0037] Figure 2 The diagram illustrates a jaw assembly 2 (right side) according to the present invention and a jaw assembly 2a (left side) in the prior art. It is evident that in the jaw assembly 2a on the left, the insulation of the conductor is injection-molded into the substrate, resulting in a larger bending radius of the conductor. Consequently, a portion of the conductor protrudes from the conductor groove when the jaws rotate. In the jaw assembly according to the present invention on the right, the substrate has a notch 15 at the location where the exposed section is fixedly connected to the jaws, and the end of the conductor insulation is movable relative to the substrate. That is, the conductor insulation does not form a material bond with the substrate; in other words, the conductor insulation is not injection-molded into the substrate.

[0038] For example, the exposed portion of the conductor is insulated and sealed by a sealant. This reliably prevents leakage and corrosion of the conductor. For instance, the sealant can be a sealant filled in a recess, completely surrounding the exposed portion of the conductor. In this embodiment, the sealant can be easily filled into the recess, thus sealing the exposed portion very simply. Furthermore, the sealant is very soft, so bending of the exposed portion of the conductor has minimal impact on the conductor's movement, ensuring the conductor remains in contact with the conductor groove. In one embodiment, the exposed portion of the conductor is entirely within the recess, and there is no direct contact between the exposed portion of the conductor and the base material. This further reduces the conductor's bending radius, thus further improving conductor safety.

[0039] from Figure 2 As can be seen from the jaw assembly 2 shown according to the invention, the base has a wire groove 17 that extends arcuately from the recessed portion. This wire groove extends approximately circularly and is connected to the recessed portion, or rather, the recessed portion transitions into the wire groove. This design allows for better adaptation to the rotation of the jaws. At the extreme open position when the jaw assembly is operating normally, the insulation of the wire is completely against the wire groove 17 (see reference...). Figure 2 (Right side view). This design allows for greater maneuverability of the jaws and further ensures that the wires do not interfere with the surgical procedure during use.

[0040] A wire rope groove 16 for guiding (not shown) a wire rope is constructed in the base, wherein the wire rope is used to pull the jaw assembly to rotate. Furthermore, in the installed state of the two jaw assemblies, the wire rope grooves of the two jaw assemblies are located between the two guide grooves. This results in a particularly compact structural design of the jaw assembly.

[0041] Reference Figures 3 to 6This invention also provides a mold 20 for manufacturing a jaw assembly of an active surgical instrument. The mold is used for injection molding an insulating substrate of the jaw assembly. The mold has a fixed mold 21 and a movable mold 22, wherein the movable mold is movable relative to the fixed mold. A mechanism assembly for clamping the wire of the jaw assembly is provided in the movable mold. The mechanism assembly has a slider groove 24, a first slider 25 and a second slider 26. The first slider and the second slider are arranged in the slider groove and are movable between a feed position and a retract position. When the first slider and the second slider are mated at the feed position, a channel 31 is formed. The channel is adapted to the wire, and the end of the channel facing the jaw assembly is adapted to the shape of the jaw, so that a notch is formed after the insulating substrate of the jaw assembly is injection molded, and the exposed portion of the wire core is located in the notch, and the end of the wire insulation is movable relative to the substrate. The mold of this invention allows for the efficient manufacture of jaw assemblies according to the invention, particularly enabling the injection molding of the substrate according to the invention, wherein a notch is retained and the insulation of the wire is not injection molded, allowing the end of the wire insulation to be movable relative to the substrate, thus achieving the aforementioned advantages. Furthermore, the mold of this invention can reliably injection mold the substrate according to the invention without concern that the wire insulation will be injection molded into the substrate or contaminated with injection material.

[0042] Figure 3 A general view of a mold 20 for manufacturing a jaw assembly is shown. The mold 20 has a fixed mold 21, a moving mold 22, and a mechanism assembly 23 disposed in the moving mold. In the process of manufacturing the jaw assembly, the jaws with wires fixed to them are first placed in the mechanism assembly 23, and then the mechanism assembly is moved with the moving mold to the injection position.

[0043] Figure 4 An exploded view of the mechanism assembly is shown. The mechanism assembly has a slider groove 24, a first slider 25, and a second slider 26. The first and second sliders are arranged in the slider groove 24 and are movable between a feed position and a retract position. The first slider has one half of a channel 31, and the second slider has the other half of a channel 31. When the two sliders are mated, a complete channel is formed, in which a wire is placed.

[0044] The first and second sliders each have a corresponding first hole, such as a spring hole, for housing an elastic element 28, such as a spring. Furthermore, when the first slider 25 and the second slider 26 are in the feed position, the elastic element 28 is compressed; when the first slider 25 and the second slider 26 are in the retracted position, the elastic element 28 pushes the first and second sliders apart. This design allows for easy separation of the first and second sliders in the retracted position, enabling quick preparation for the next injection molding and achieving good operability.

[0045] The first slider and the second slider each have a corresponding second hole, such as a positioning hole, in which a positioning element 27, such as a positioning pin, is placed. Figure 4 The diagram shows two sets of positioning holes and two positioning pins. This design enables precise alignment of the first and second sliders, providing reliable accuracy for injection molding.

[0046] The mechanism assembly includes a push rod 30, and the first and second sliders each have corresponding grooves for accommodating the ends of the push rod. Therefore, the push rod 30 can move the two sliders between a feed position and a retract position, resulting in convenient operability.

[0047] The slide groove has a wider internal space at the exit position compared to the feed position. The first and second slides separate at the exit position and engage at the feed position. This allows for rapid and reliable movement of the first and second slides, improving the efficiency of injection molding.

[0048] In one embodiment, the space within the slot continuously widens from the feed position to the exit position. In this manner, the two sliders can move between the feed and exit positions with minimal resistance.

[0049] In one embodiment, the space within the slot has a constant first width from the feed position and a constant second width at the exit position, the second width being greater than the first width. This design allows for more stable movement of the two sliders at both the feed and exit positions.

[0050] Figure 5 This shows a view of jaw 9 before injection molding. Figure 5 In the process, the first and second sliders are in the feed position, and the end of the channel is in contact with the jaws 9. The end of the channel is formed by the first protruding structure 32 of the first slider and the second protruding structure 33 of the second slider, and the first protruding structure 32 and the second protruding structure 33 form a tubular structure, the outer diameter of which corresponds to the inner diameter of the recess. Here, the outer diameter of the tubular structure corresponds to the inner diameter of the recess in the molded substrate. During the injection molding process, the insulation of the wire can partially extend into the tubular structure. The free end face of the tubular structure fits tightly with the jaws 9, so the injection-molded plastic does not enter the tubular structure. Therefore, after molding, the position of the tubular structure forms the recess in the substrate, and the exposed portion of the wire core is located within the recess. Thus, the exposed portion of the wire core does not directly contact the substrate material, that is, the exposed portion does not contact the injection-molded material.

[0051] Figure 6 This shows a view of the jaws 9 after injection molding, with the slider in the feed and retract positions. Figure 5 In comparison, Figure 6The left-hand view shows the injection-molded substrate 11. In this view, the two sliders are still in the feed position, where they clamp the wire, and the substrate forms a notch according to the invention, where the wire is not injection-molded; more precisely, the wire insulation is not injection-molded into the substrate and is not connected to it. In the right-hand view, the two sliders are in the retracted position. Due to the widened structure of the slider groove, the two sliders are spring-pushed open in this position, so the wire is no longer clamped by the two sliders, and the injection-molded jaw assembly can be removed. After injection molding is complete, the next jaw can be quickly inserted for injection molding; the two sliders can be quickly pushed back to the feed position for injection molding.

[0052] The mold according to the present invention can manufacture the jaw assembly according to the present invention, and in particular, can manufacture a special injection-molded structure for the connection between the wire and the jaw, so that the wire can achieve a very small bending radius, thereby conforming well to the wire groove during surgery. The mold according to the present invention also has high efficiency, allowing for rapid insertion and removal of the jaw assembly during injection molding. Simultaneously, the mold also has high stability because the design of the slider groove allows the slider to move very stably between the feed and retraction positions, and because the slider groove is also designed with a limit pin, positional accuracy is guaranteed.

[0053] This invention also provides a method for manufacturing a jaw assembly for an active surgical instrument, wherein the jaw assembly has a wire, a conductive jaw, and an insulating substrate surrounding a pivot section of the jaw, the method comprising the following steps: - Prepare the conductor and clamps, wherein the conductor has a core and insulation, and the core is exposed at the end of the conductor to form an exposed section. - The pivot section of the clamp jaws is electrically and securely connected to the exposed section of the conductor core. - The jaws and exposed sections are injection molded so that the insulating substrate surrounding the pivot section of the jaws is injection molded, and the substrate has a notch at the position where the exposed section is fixedly connected to the jaws, and the exposed section of the conductor is located in the notch, and the end of the conductor insulation is movable relative to the substrate.

[0054] The method of this invention can produce a special injection-molded structure for the connection between the wire and the jaw, so that the wire can achieve a very small bending radius. Therefore, it will not rub against the surrounding tissue during use, nor will it affect the doctor's operation during surgery.

[0055] For example, the method according to embodiments of the present invention further includes: insulating and sealingly surrounding the exposed portion of the conductor with a sealing element. This reliably prevents leakage and corrosion of the conductor.

[0056] For example, the method according to an embodiment of the invention further includes filling the recess with sealant so that the sealant completely surrounds the exposed portion of the conductor. In this embodiment, the sealant can be easily filled into the recess, thus sealing the exposed portion is accomplished in a very simple way. Furthermore, the sealant is very soft, so bending of the exposed portion of the conductor has virtually no impact on the movement of the conductor, thereby ensuring that the conductor remains in contact with the conductor groove.

[0057] Furthermore, the method of this embodiment can also be implemented in conjunction with the mold of this embodiment. In this method, the jaws and the wire are placed in a moving mold, and the wire is clamped in a channel formed by a first slider and a second slider. Preferably, the insulation of the wire protrudes from the end of the channel, and the end of the channel mates with the jaws (in a form-fitting manner). Then, the moving mold is moved to a position corresponding to the fixed mold, and the jaws and the exposed portion are injection molded. Thus, the insulating substrate surrounding the pivoting portion of the jaws is injection molded, and the substrate has a notch at the position where the exposed portion is fixedly connected to the jaws (because the tubular structure at the end of the channel forms a closed space with the jaws). The exposed portion of the wire core is located within the notch, and the end of the wire insulation is movable relative to the substrate. By using the mold according to this invention, the efficiency and stability of the above method can be improved, providing a reliability guarantee for the correspondingly manufactured jaw assembly.

[0058] Those skilled in the art should understand that the specific embodiments described above are merely examples and not limitations. Various modifications, combinations, partial combinations, and substitutions can be made to the embodiments of the present invention according to design requirements and other factors, as long as they are within the scope of the appended claims or their equivalents, and thus fall within the scope of the rights to be protected by the present invention.
