Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a surgical clamp and medical device. Background Technology

[0002] Monopolar medical devices play a crucial role in single-port surgery. Their working principle involves conducting high-frequency current from the electrosurgical device to the surgical clamp, enabling electrocoagulation, electroresection, and other surgical procedures upon contact with the tissue. Simultaneously, the high-frequency current flows through the tissue back to the electrosurgical device via a neutral current. Unlike bipolar devices, the distal electrodes of monopolar medical devices do not require insulation. Furthermore, because the voltage and power of monopolar medical devices are higher than those of bipolar devices, their insulation methods differ.

[0003] In related technologies, surgical clamps typically include a base, two clamps, a drive structure, an insulation structure, and an electrical connection structure. Both clamps are mounted on the base. The drive structure is used to open and close the two clamps. The electrical connection structure is used to introduce high-frequency current into the two clamps. The insulation structure is used to insulate the structures within the surgical clamps (excluding the clamps) from the tissue. Because surgical clamps require high compactness, it is necessary to consider driving the opening and closing of the two clamps within a limited space. That is, while ensuring reasonable and reliable cable arrangement and insulation, sufficient drive space must be reserved. The insulation structure of existing surgical clamps is relatively complex, making it impossible to achieve insulation while reserving sufficient drive space within a small area, resulting in low compactness of the surgical clamps. Summary of the Invention

[0004] The purpose of this application is to provide a surgical clamp and medical device to solve the problem that the insulation structure of surgical clamps in the prior art is relatively complex.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, embodiments of this application provide a surgical clamp, the surgical clamp comprising:

[0007] The base includes an insulating base and a conductive base. One end of the insulating base is connected to a flexible joint, and the other end of the insulating base is connected to the conductive base. The conductive base is electrically connected to a power source.

[0008] The first clamp and the second clamp are both disposed on the conductive base;

[0009] A drive wheel is rotatably mounted on the base, and the drive wheel is used to drive the first clamp to rotate relative to the conductive base and / or the second clamp to rotate relative to the conductive base;

[0010] A first cable, comprising an insulated rope segment, is wound around the drive wheel for driving the drive wheel to rotate.

[0011] In one embodiment, the insulating base has a first through hole, and the conductive base has a second through hole. The first through hole and the second through hole are interconnected. The surgical clamp also includes a cable that passes through the first through hole and the second through hole, and both ends of the cable are electrically connected to the power source and the conductive base, respectively.

[0012] In one embodiment, the transmission wheel is rotatably mounted on the conductive base, the insulating base has a third through hole, and the conductive base has a fourth through hole that communicates with the third through hole. The third through hole and the fourth through hole are used to thread the first rope through, and the diameter of the fourth through hole gradually increases in the direction from the insulating base to the conductive base.

[0013] In one embodiment, a protective sleeve is provided on the outer side of the first rope. The protective sleeve is disposed at the junction of the third through hole and the fourth through hole, and at least a portion of one end of the protective sleeve extends and passes through the third through hole, and at least a portion of the other end of the protective sleeve extends and passes through the fourth through hole.

[0014] In one embodiment, the insulating base includes an insulating base body and a gasket with a strength greater than that of the insulating base body. The outer peripheral wall of the insulating base body is provided with a mounting groove, and the gasket is embedded in the mounting groove.

[0015] In one embodiment, the surgical clamp further includes a first rotating shaft and a second rotating shaft arranged parallel to each other. The first clamp is rotatably mounted on the conductive base via the first rotating shaft, and the second clamp is rotatably mounted on the conductive base via the second rotating shaft.

[0016] In one embodiment, at least one of the first clamp and the second clamp is provided with a limiting hole, and the surgical clamp further includes a third rotating shaft, the third rotating shaft, the first rotating shaft and the second rotating shaft are parallel to each other, the transmission wheel is rotatably disposed on the conductive base through the third rotating shaft, and the third rotating shaft passes through the limiting hole and slides in cooperation with the limiting hole.

[0017] In one embodiment, the transmission wheel includes a transmission wheel body and a first sliding shaft and a second sliding shaft respectively disposed on opposite sides of the transmission wheel body. The first sliding shaft, the second sliding shaft and the third rotating shaft are parallel to each other, and the line connecting the first sliding shaft and the second sliding shaft passes through the third rotating shaft.

The medical device also includes a flexible joint and a driving device. The flexible joint is connected to the insulating base, and the driving device is used to drive the flexible joint and to drive the first cable to move, thereby causing the surgical clamp to move.

[0021] The beneficial effects of the surgical clamp provided in this application embodiment are as follows: Since the base includes an insulating seat and a conductive seat, one end of the insulating seat is connected to a flexible joint, and the other end of the insulating seat is connected to the conductive seat, the first clamp and the second clamp are both disposed on the conductive seat, and the transmission wheel is rotatably disposed on the base, the first cable includes an insulating rope segment, which is wound around the transmission wheel. Therefore, in the process of driving the transmission wheel to rotate through the insulating rope segment, thereby driving the first clamp to rotate relative to the conductive seat and / or the second clamp to rotate relative to the conductive seat, not only can the insulating seat achieve insulation between the first clamp, the second clamp, the conductive seat as a whole and the flexible joint, but also the insulating rope segment can achieve insulation between the first clamp, the second clamp, the conductive seat, the transmission wheel as a whole and the driving device connected to the insulating rope segment. Its structure is relatively simple and can improve the compactness of the surgical clamp.

[0044] In related technologies, surgical clamps typically include a base, two clamps, a drive structure, an insulation structure, and an electrical connection structure. The two clamps are mounted on the base. The drive structure is used to open and close the two clamps. The electrical connection structure is used to introduce high-frequency current into the two clamps. The insulation structure is used to insulate the structures within the surgical clamps (excluding the clamps) from the tissue. Because surgical clamps require high compactness, it is necessary to consider driving the opening and closing of the two clamps within a limited space. That is, while ensuring reasonable and reliable cable arrangement and insulation, sufficient drive space must be reserved. The insulation structure of existing surgical clamps is relatively complex, making it impossible to achieve insulation while reserving sufficient drive space within a small area, resulting in low compactness of the surgical clamps.

[0045] To address the aforementioned issues, this application provides a surgical clamp and medical device that can resolve the problem of complex insulation structures in existing surgical clamps.

[0046] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the surgical clamp provided in the embodiments of this application. Figure 2 This is a schematic diagram of the exploded structure of the surgical clamp provided in the embodiment of this application.

[0047] In a first aspect, embodiments of this application provide a surgical clamp, which includes a base 100, a first clamp 200, a second clamp 300, a drive wheel 400, and a first cable 500.

[0048] The base 100 includes an insulating base 110 and a conductive base 120. One end of the insulating base 110 is connected to a flexible joint, and the other end of the insulating base 110 is connected to the conductive base 120. The conductive base 120 is electrically connected to a power source.

[0049] The insulating base 110 is insulating, thus the flexible joint is insulated from the conductive base 120.

[0050] The first clamp 200 and the second clamp 300 are both disposed on the conductive base 120. The transmission wheel 400 is rotatably disposed on the base 100 and is used to drive the first clamp 200 to rotate relative to the conductive base 120 and / or the second clamp 300 to rotate relative to the conductive base 120.

[0051] The first rope 500 includes an insulated rope segment 510, which is wound around the transmission wheel 400 and used to drive the transmission wheel 400 to rotate.

[0052] The insulating rope segment 510 is insulating, thus insulating the drive device connected to the insulating rope segment 510 from the transmission wheel 400.

[0053] The first clamp 200 and the second clamp 300 do not need to be insulated from each other. The conductive base 120, the first clamp 200 and the second clamp 300 are all energized.

[0054] The first clamp 200 is rotatably connected to the conductive base 120, and the second clamp 300 is fixedly connected to the conductive base 120. The insulating rope segment 510 is used to drive the transmission wheel 400 to rotate. The transmission wheel 400 drives the first clamp 200 to rotate relative to the conductive base 120, so that the first clamp 200 and the second clamp 300 clamp the object being clamped.

[0055] Alternatively, the second clamp 300 is rotatably connected to the conductive base 120, the first clamp 200 is fixedly connected to the conductive base 120, and the insulating rope segment 510 is used to drive the transmission wheel 400 to rotate. The transmission wheel 400 drives the second clamp 300 to rotate relative to the conductive base 120, so that the first clamp 200 and the second clamp 300 clamp the object being clamped.

[0056] Alternatively, both the first clamp 200 and the second clamp 300 are rotatably connected to the conductive base 120, and the insulating rope segment 510 is used to drive the transmission wheel 400 to rotate. The transmission wheel 400 drives the first clamp 200 to rotate relative to the conductive base 120 and the second clamp 300 to rotate relative to the conductive base 120, so that the first clamp 200 and the second clamp 300 clamp the object being clamped.

[0057] The surgical clamp provided in this embodiment includes an insulating base 100 and a conductive base 120. One end of the insulating base 110 is connected to a flexible joint, and the other end is connected to the conductive base 120. Both the first clamp 200 and the second clamp 300 are mounted on the conductive base 120, and the drive wheel 400 is rotatably mounted on the base 100. The first cable 500 includes an insulating rope segment 510, which is wound around the drive wheel 400. Therefore, the insulating rope segment 510 drives the drive wheel 400 to rotate, thereby driving the first clamp. During the rotation of the first clamp 200 relative to the conductive base 120 and / or the rotation of the second clamp 300 relative to the conductive base 120, the insulating base 110 can not only achieve insulation between the first clamp 200, the second clamp 300, the conductive base 120 as a whole and the flexible joint, but also achieve insulation between the first clamp 200, the second clamp 300, the conductive base 120 and the transmission wheel 400 as a whole and the drive device connected to the insulating rope segment 510. Its structure is relatively simple and can improve the compactness of the surgical clamp.

[0058] The surgical clamp provided in this application has a simple transmission structure, requires no secondary conversion, and has high transmission efficiency. The surgical clamp provided in this application is not limited to active instruments, but can also be used with passive instruments; it is not limited to single-port instruments, but can also be used in other areas of the medical industry.

[0059] Optionally, the base 100 includes a pin 130, which can be integrated with the conductive base 120. The insulating base 110 is provided with a pin hole 115 that is adapted to the pin 130.

[0060] Optionally, the insulating rope segment 510 includes a rope head and a rope tail, and the drive wheel 400 is provided with a groove. The rope head and rope tail are respectively connected to the non-insulated rope segment of the first rope 500. The middle part of the insulating rope segment 510 is fixed in the groove, such as by mechanical fitting, bonding or welding.

[0061] Please refer to this as well. Figure 3 and Figure 4 , Figure 3 This is an exploded structural diagram of the base 100 of the surgical clamp provided in this embodiment of the application. Figure 4 This is a cross-sectional view of the surgical clamp provided in an embodiment of this application.

[0062] In this embodiment, the insulating base 110 is provided with a first through hole 111, and the conductive base 120 is provided with a second through hole. The first through hole 111 and the second through hole are interconnected. The surgical clamp also includes a cable 600, which passes through the first through hole 111 and the second through hole, and both ends of the cable 600 are electrically connected to the power supply and the conductive base 120, respectively.

[0063] By adopting the above solution, the cable 600 can be housed within the base 100, thus preventing the cable 600 from occupying external space of the base 100 and causing the surgical clamp to be less compact. Furthermore, since the cable 600 is connected to the conductive base 120, and both the first clamp 200 and the second clamp 300 are located on the conductive base 120, the opening and closing process of the first clamp 200 and the second clamp 300 has no impact on the cable 600, improving the stability of the surgical clamp.

[0064] The transmission wheel 400 is rotatably mounted on the conductive seat 120. The insulating seat 110 is provided with a third through hole 112, and the conductive seat 120 is provided with a fourth through hole 121 that communicates with the third through hole 112. The third through hole 112 and the fourth through hole 121 are used to thread the first rope 500 through. The diameter of the fourth through hole 121 gradually increases in the direction from the insulating seat 110 to the conductive seat 120.

[0065] This design allows the first cable 500 to be housed within the base 100, thus preventing the first cable 500 from occupying external space of the base 100 and resulting in low compactness of the surgical clamp. Furthermore, the diameter of the fourth through hole 121 gradually increases from the insulating base 110 to the conductive base 120, allowing the diameter of the third through hole 112 to be smaller, reducing the space occupied by the third through hole 112. Simultaneously, it allows for a smooth transition of the first cable 500 through the fourth through hole 121 as it extends from the fourth through hole 121 to the third through hole 112, preventing abrupt changes in the bending angle and sharp turns.

[0066] Optionally, the non-conductive portion of the cable 600 may be housed inside the insulating base 110.

[0067] Please refer to this as well. Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the surgical clamp for removing the conductive base 120 provided in an embodiment of this application, viewed from a first perspective. Figure 6 This is a schematic diagram of the surgical clamp for removing the conductive base 120 provided in an embodiment of this application from a second perspective.

[0068] Since the first rope 500 will bend when passing through the third through hole 112 and the fourth through hole 121, in order to avoid wear of the first rope 500 during force transmission, a protective sleeve 530 is optionally provided on the outside of the first rope 500. The protective sleeve 530 is located at the junction of the third through hole 112 and the fourth through hole 121, and at least a portion of one end of the protective sleeve 530 extends and passes through the third through hole 112, and at least a portion of the other end of the protective sleeve 530 extends and passes through the fourth through hole 121.

[0069] This design prevents the first rope 500 from wearing out and breaking at the junction of the third through hole 112 and the fourth through hole 121.

[0070] For example, the protective sleeve 530 may be a plastic protective sleeve with a low coefficient of friction to reduce wear.

[0071] The first cable 500 may include a traction cable segment 520 connected to the insulating cable segment 510. The insulating cable segment 510 is wound around the drive wheel 400, and the traction cable segment 520 is connected to the end of the insulating cable segment 510 and is used to connect to the drive device.

[0072] Specifically, the insulating rope segment 510 can be a rope woven from non-conductive aramid fibers. The traction rope segment 520 can be a metal wire braided rope with greater strength than the insulating rope segment 510. To ensure tensile strength, the insulating rope segment 510 and the traction rope segment 520 can be fixedly connected by crimping using a fastener, which can be a thin-walled hollow metal tube. To avoid the sharp edges breaking the rope during crimping, the crimping position is slightly away from both ends of the fastener.

[0073] At least a portion of the traction rope segment 520 and / or a portion of the insulating rope segment 510 near the traction rope segment 520 are fitted with a spring tube 540.

[0074] Optionally, the insulating base 110 includes an insulating base body 113 and a gasket 114 with a strength greater than that of the insulating base body 113. The outer peripheral wall of the insulating base body 113 is provided with a mounting groove 1131, and the gasket 114 is embedded in the mounting groove 1131.

[0075] By adopting the above solution, the stability of the connection between the insulating seat 110 and the joint rope 900 that controls the movement of the flexible joint can be increased by the gasket 114.

[0076] Specifically, the gasket 114 can be a metal gasket 114. The gasket 114 can increase the stability of the connection between the insulating seat 110 and the joint cable 900 that controls the movement of the flexible joint.

[0077] Specifically, the insulating base 110 may be provided with four connecting through holes 116 for placing the articulated rope 900. Since the outer diameter of the articulated rope 900 is small and the contact area with the insulating base 110 is small, the stress of the articulated rope 900 on the insulating base 110 is relatively large. However, in this embodiment, the pressure of the articulated rope 900 on the insulating base 110 can be borne by the gasket 114.

[0078] Optionally, an insulating sleeve 700 is provided on the outer side of the conductive base 120, and the end of the first clamp 200 away from the conductive base 120 and the end of the second clamp 300 away from the conductive base 120 both extend to the outside of the insulating sleeve 700.

[0079] This design insulates the conductive base 120 from the external space of the insulating sleeve 700, preventing damage to healthy tissue during the operation of the surgical clamps.

[0080] To prevent the insulating sleeve 700 from slipping off the conductive base 120, a boss 800 is provided on the outer layer of the insulating base 110, and the boss 800 is tightly connected to the insulating sleeve 700.

[0081] Please refer to Figure 2 , Figure 5 and Figure 6 In this embodiment, the surgical clamp also includes a first rotating shaft 910 and a second rotating shaft 920 arranged parallel to each other. The first clamp 200 is rotatably mounted on the conductive base 120 via the first rotating shaft 910, and the second clamp 300 is rotatably mounted on the conductive base 120 via the second rotating shaft 920.

[0082] By adopting the above scheme, the first clamp 200 and the second clamp 300 can be synchronously rotated and opened and closed through the transmission wheel 400, and the opening and closing angles of the first clamp 200 and the second clamp 300 are the same.

[0083] Specifically, the first rotating shaft 910 and the second rotating shaft 920 pass through the rotation center of the first clamp 200 and the rotation center of the second clamp 300, respectively, and the first rotating shaft 910 and the second rotating shaft 920 are not coaxial. Both the first rotating shaft 910 and the second rotating shaft 920 can be connected to the conductive base 120 by means of riveting, laser welding, adhesive bonding, and mechanical fitting.

[0084] Understandably, since both the first clamp 200 and the second clamp 300 need to be energized, when both the first rotating shaft 910 and the second rotating shaft 920 are conductive, the conductive base 120 can be electrically connected to the first clamp 200 and the second clamp 300.

[0085] At least one of the first clamp 200 and the second clamp 300 is provided with a limiting hole 210. The surgical clamp also includes a third rotating shaft 930. The third rotating shaft 930, the first rotating shaft 910, and the second rotating shaft 920 are parallel to each other. The transmission wheel 400 is rotatably mounted on the conductive base 120 via the third rotating shaft 930. The third rotating shaft 930 passes through the limiting hole 210 and slides in cooperation with the limiting hole 210. This arrangement allows the transmission wheel 400 to drive the first clamp 200 and the second clamp 300 to rotate and open and close synchronously. The limiting hole 210 can firstly avoid the third rotating shaft 930, so that the third rotating shaft 930 does not interfere with the first clamp 200 and / or the second clamp 300. Secondly, the limiting hole 210 can also limit the opening angle of the clamp jaws.

[0086] Understandably, since both the first clamp 200 and the second clamp 300 are energized, the transmission wheel 400 will also be energized when it is conductive. Furthermore, because the non-conductive insulating rope segment 510 is wound around the transmission wheel 400, the surgical clamps will not conduct current through the first rope 500 to other parts of the medical device. Combined with the insulating effect of the insulating base 110, the purpose of insulation between the conductive base 120 and other parts can be achieved.

[0087] Specifically, the transmission wheel 400 includes a transmission wheel body 410 and a first sliding shaft 420 and a second sliding shaft 430 respectively disposed on opposite sides of the transmission wheel body 410. The first sliding shaft 420, the second sliding shaft 430 and the third rotating shaft 930 are parallel to each other, and the line connecting the first sliding shaft 420 and the second sliding shaft 430 passes through the third rotating shaft 930. The first clamp 200 is provided with a first sliding groove 220 that slides with the first sliding shaft 420, and the second clamp 300 is provided with a second sliding groove 310 that cooperates with the second sliding shaft 430.

[0088] With this configuration, the first clamp 200 and the second clamp 300 can be driven to rotate and open and close synchronously via the transmission wheel 400, and the opening and closing angles of the first clamp 200 and the second clamp 300 are the same.

[0089] Please refer to Figure 2 and Figure 3 In this embodiment, the surgical clamp includes a first elastic member 940, which abuts against the first clamp 200. The first elastic member 940 is used to apply an elastic force to the first clamp 200 to bring the first clamp 200 closer to the second clamp 300.

[0090] The surgical clamp includes a second elastic element 950 that abuts against a second clamp 300. The second elastic element 950 is used to apply a spring force to the second clamp 300 to bring the second clamp 300 closer to the first clamp 200.

[0091] By adopting the above scheme, the first elastic element 940 can be used to apply a spring force to the first clamp 200, causing the first clamp 200 to move closer to the second clamp 300, thereby avoiding a gap between the first clamp 200 and the second clamp 300 during the shearing process. The second elastic element 950 can be used to apply a spring force to the second clamp 300, causing the second clamp 300 to move closer to the first clamp 200, thereby avoiding a gap between the first clamp 200 and the second clamp 300 during the shearing process.

[0092] Specifically, both the first elastic element 940 and the second elastic element 950 can be made of elastic gasket 114, spring, or elastic rubber sleeve, etc. The elastic gasket 114 has a certain thickness and elasticity. After assembly, the elastic gasket 114 is in a compressed state to ensure that the first clamp 200 and the second clamp 300 are in close contact.

[0093] For example, the conductive base 120 may be provided with an assembly groove, in which the first clamp 200 and the second clamp 300 are both located. The first elastic member 940 is located between the inner wall of the assembly groove and the first clamp 200, and the second elastic member 950 is located between the inner wall of the assembly groove and the second clamp 300. The conductive base 120 may be U-shaped.

[0094] Secondly, this application provides a medical device including the surgical clamp of the first aspect. The medical device also includes a flexible joint and a driving device. The flexible joint is connected to the insulating seat 110. The driving device is used to drive the flexible joint and to drive the first cable 500 to move, thereby driving the surgical clamp to move.

[0095] The medical device provided in this application embodiment has a surgical clamp base 100 that includes an insulating base 110 and a conductive base 120. One end of the insulating base 110 is connected to a flexible joint, and the other end of the insulating base 110 is connected to the conductive base 120. The first clamp 200 and the second clamp 300 are both disposed on the conductive base 120, and the transmission wheel 400 is rotatably disposed on the base 100. Therefore, the first cable 500 includes an insulating rope segment 510, which is wound around the transmission wheel 400. Thus, the transmission wheel 400 is driven to rotate by the insulating rope segment 510, thereby driving the first clamp 200. During the rotation of the conductive base 120 and / or the rotation of the second clamp 300 relative to the conductive base 120, the insulating base 110 can not only achieve insulation between the first clamp 200, the second clamp 300, the conductive base 120 as a whole and the flexible joint, but also achieve insulation between the first clamp 200, the second clamp 300, the conductive base 120, the transmission wheel 400 as a whole and the drive device connected to the insulating rope segment 510. Its structure is relatively simple, which can improve the compactness of the surgical clamp, and thus improve the compactness of the medical device.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
