Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multifunctional, controllable-angle electric cutting and coagulation device for laparoscopy. Background Technology

[0002] In gynecological laparoscopic minimally invasive surgery, the safe and efficient cutting and reliable hemostasis of tissues such as the uterus, adnexa, and ligaments are core steps. Currently commonly used instruments include: monopolar / bipolar electrocoagulation forceps: primarily used for hemostasis and tissue coagulation, but with low cutting efficiency and limited ability to sever large blood vessel bundles or thicker tissues (such as the uterosacral ligament and uterine artery), and prone to tissue adhesion and eschar formation. Ultrasonic scalpel: possesses cutting and coagulation functions, with a smaller thermal damage area, but its coagulation speed and reliability are sometimes insufficient for dense, vascularized tissues, and the equipment is expensive. Linear cutting and closing device: mainly used for severing and closing intestinal loops and large blood vessel bundles, and can be used to manage uterine vessels in gynecological surgery. However, its large instrument tip and fixed operating angle result in poor flexibility in narrow or tricky deep pelvic areas (such as when dealing with the uterosacral ligament and paracervical tissue), and the staple cartridge is a disposable consumable, leading to high costs. Traditional scissors or L-hook electrocoagulation: This method relies heavily on the surgeon's skill, with cutting and hemostasis performed step-by-step, resulting in low efficiency and requiring a high degree of visualization of the surgical area. Currently, there is an urgent clinical need for a comprehensive instrument that integrates efficient cutting, reliable coagulation, and flexible multi-angle operation, while also reducing the learning curve and surgical costs.

[0003] However, existing auxiliary devices for mannitol infusion have several shortcomings: 1. The working ends of most existing cutting / coagulation instruments are straight or have fixed bends, making it difficult to adapt to the complex three-dimensional anatomical structure of the pelvis. Especially when dealing with tissues behind the uterus and the lateral pelvic wall, there are often "dead angles," forcing the surgeon to use suboptimal angles for forced operation, increasing the risk of collateral damage; 2. The instruments have limited functions, with each device only capable of one of the functions of cutting, coagulation, or separation. Frequent changes of different instruments are required during the operation, increasing the risk of instrument contamination and causing additional damage to tissues due to repeated entry and exit of instruments into the abdominal cavity, prolonging the operation time. Furthermore, switching between multiple instruments can easily lead to human judgment errors, affecting the safety of the operation. Summary of the Invention

[0004] This invention provides a multifunctional, controllable-angle electric cutting and coagulation device for laparoscopy, which solves the technical problems of existing cutting / coagulation instruments with straight or fixed-angle working ends, which are difficult to adapt to the complex structure of the pelvic cavity, have blind spots, increase the risk of collateral damage, have limited functions and require frequent replacement, increase the risk of contamination and tissue damage, prolong the operation time and affect safety.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A multifunctional, controllable-angle electric cutting and coagulation device for laparoscopy includes a gun-shaped handle. A connecting seat is installed on the side wall of the gun-shaped handle. The connecting seat is detachably connected to a docking seat via a quick-release assembly. Multiple first medical supports are installed on the side wall of the docking seat. The ends of the multiple first medical supports are connected to a common first joint block. A rotating seat is installed on the side wall of the first joint block. A rotating rod is rotatably connected between the rotating seats. A rotating block is fixedly connected to the rotating rod. Multiple second medical supports are fixedly connected to the bottom of the rotating block. The bottom of the multiple second medical supports is fixedly connected to the same second joint block. A power assembly is provided on the outer wall of the rotating rod, and the power assembly drives the rotating rod to rotate.

[0007] An angle adjustment limit component is located on the side wall of the first joint block; it is used to adjust the rotation angle of the rotating rod.

[0008] A multi-functional switching component is located at the bottom of the second joint block and is used for switching devices.

[0009] Optionally, the quick-release assembly includes pin holes, with multiple pin holes evenly distributed in a circumferential array on the side wall of the connector seat, and multiple pin rods evenly distributed in a circumferential array on the side wall of the mating seat. Each pin hole supports a sliding connection of one pin rod, and the outer wall of the pin rod has a slot. Multiple strong springs are provided inside one side of the connector seat, with one end of each strong spring fixedly connected to the inner side wall of the connector seat. The multiple strong springs are evenly distributed in a circumferential array on the side wall of the connector seat, and the number of strong springs is equal to the number of pin holes, with each spring corresponding to a specific position. The extension direction of each strong spring is the same as the radial direction of the connector seat. A retaining plate that matches the slot is fixedly connected to the end of each strong spring away from the inner wall of the connector seat. A pressing rod is fixedly connected to the side wall of the retaining plate, and the axis of the pressing rod is perpendicular to the side wall of the connector seat.

[0010] Each of the card plates has two guide rods slidably connected to its sidewall facing the strong spring, and the other ends of the two guide rods are fixedly connected to the inner wall of the connecting seat.

[0011] Optionally, the angle adjustment limiting component includes a side frame, which is fixedly connected to the side wall of the first joint block;

[0012] The power assembly includes a first drive motor, which is fixedly connected to the side wall of the side frame, and a worm is fixedly connected to the output end of the first drive motor. The outer wall of the worm meshes with the outer wall of the worm wheel, and the worm wheel is fixedly connected to the outer wall of the rotating rod.

[0013] Optionally, the multi-function switching component includes:

[0014] A medical housing is fixedly connected to the bottom of the second joint block, and a second drive motor is fixedly connected to the inner top wall of the medical housing. The output end of the second drive motor is fixedly connected to a drive gear that is rotatably connected to the medical housing.

[0015] Multiple sets of screws are rotatably connected to the inner wall of the medical housing and symmetrically distributed about the vertical direction of the medical housing. A driven gear that meshes with the drive gear is fixedly connected to the top of each screw.

[0016] Multiple guide frames are fixedly connected to the inner wall of the medical housing and symmetrically distributed about the vertical direction of the medical housing; the number of guide frames is equal to the number of screws;

[0017] The lifting block is threaded to the outer wall of the screw, and a moving block is slidably connected to the side wall of the lifting block. A driven rod is fixedly connected to the side wall of the moving block, and the driven rod is located on the inner wall of the guide frame and slidably connected to the inner wall of the guide frame.

[0018] Optionally, a drive plate is rotatably connected to the inner wall of the connecting seat, and multiple sets of extrusion grooves are provided on the side wall of the drive plate in a circular pattern along the drive plate, and the extrusion grooves are sleeved on the outer wall of the extrusion rod.

[0019] Optionally, a flexible frame is fixedly connected to the bottom of the movable block. The flexible frame is located at the bottom of the lifting block, and a mounting plate is fixedly connected to the bottom end of the flexible frame. The mounting plate is located outside the medical housing, and surgical instruments are mounted on the mounting plate.

[0020] Optionally, an electric push rod is fixedly connected to the inner wall of the medical housing, and a blunt dissection forceps is also fixedly connected to the inner wall of the medical housing, with one of the handles of the blunt dissection forceps fixedly connected to the output end of the electric push rod.

[0021] Optionally, a sealing shell is fixedly connected to the top of the side frame, and the sealing shell is sleeved on the outer wall of the worm gear.

[0022] Optionally, the sidewall of the pistol grip has multiple sets of grip grooves that are linearly distributed along the edge of the pistol grip. A touch screen is fixedly connected to the sidewall of the pistol grip, and the touch screen is electrically connected to the first drive motor, the second drive motor, and the electric push rod.

[0023] Optionally, an angle sensor is fixedly connected to one side wall of the rotating seat. The angle sensor cooperates with the rotating rod and is electrically connected to the touch screen. The beneficial effects of the above technical solution of the present invention are as follows:

[0024] In the above solution, the angle adjustment is achieved through a motor-driven worm gear mechanism, which also has a self-locking characteristic, effectively preventing accidental angle displacement during surgery and ensuring mechanical stability. With the real-time feedback and digital display of the angle sensor, the surgeon can precisely control the angle and flexibly handle deep or tricky tissue operations, greatly improving the accessibility and precision of the surgery. This solves the problem that the straight or fixed-angle working end of the cutting / coagulation instruments in the existing technology is difficult to adapt to the complex structure of the pelvic cavity, resulting in blind spots and increased collateral damage.

[0025] The mounting plate can be adapted to various functional instruments such as bipolar coagulation, high-frequency cutting, and blunt dissection. The multi-functional switching component enables adaptive switching, eliminating the need to change surgical instruments midway, reducing the risk of contamination from frequent instrument changes, minimizing additional tissue damage caused by instruments entering and exiting the abdominal cavity, and shortening the operation time. At the same time, integrated operation reduces human judgment errors and improves surgical safety. The high-temperature resistant and anti-adhesion coating further optimizes the surgical experience and prevents tissue adhesion from affecting the operation. This solves the problems of existing technologies that require frequent changes due to single functions, increasing the risk of contamination and tissue damage, prolonging the operation time, and affecting safety.

[0026] The quick-release components enable rapid replacement of the actuators, allowing for flexible adaptation to different surgical needs or emergency replacement scenarios during surgery. Meanwhile, all drives and controls are integrated into the handle and centrally managed via a touchscreen, reducing preoperative instrument assembly time and the number of times instruments enter and exit the abdominal cavity during surgery, thus reducing the workload of the scrub nurse. It also shortens the surgical cleanup time and facilitates later maintenance. Attached Figure Description

[0039] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 10 As shown, an embodiment of the present invention provides a laparoscopic multifunctional controllable angle electric cutting and coagulation device, including a gun-type handle 1, and further comprising:

[0041] Connector 3 is fixedly connected to the side wall of gun handle 1, and connector 3 is detachably connected to docking seat 7 via quick-release assembly. A micro vibration motor can be installed inside gun handle 1 to provide the operator with different modes of vibration prompts when the working end completes tissue coagulation or encounters abnormal resistance.

[0042] Multiple sets of first medical stents 15 are fixedly connected to the side wall of the docking seat 7 away from the connecting seat 3 and are symmetrically distributed about the docking seat 7 in the vertical direction; in this embodiment, there are two first medical stents 15.

[0043] The first joint block 16 is fixedly connected to one end of the first medical support 15. Multiple first medical supports 15 have the same first joint block 16 fixedly connected to the same side end. Multiple sets of rotating seats 20, symmetrically distributed vertically about the first joint block 15, are fixedly connected to the side wall of the first joint block 16 away from the first medical support 15. In this embodiment, there are two rotating seats 20. A rotating rod 21 is rotatably connected between the symmetrical rotating seats 20, and a rotating block 22 is fixedly connected to the outer wall of the rotating rod 21.

[0044] Multiple sets of second medical stents 23 are fixedly connected to the bottom of the rotating block 22 and are symmetrically distributed about the vertical direction of the rotating block 22; in this embodiment, there are two second medical stents 23. The rotating block 22 includes a disc-shaped bottom connected to the second medical stents 23 and a protrusion fixedly connected to the rotating rod 21.

[0045] The second joint block 24 is fixedly connected to the bottom of the second medical bracket 23; the bottoms of the two second medical brackets 23 are fixedly connected to the same second joint block 24.

[0046] The worm gear 25 is fixedly connected to the outer wall of the rotating rod 21;

[0047] An angle adjustment limit component is provided on the side wall of the first joint block 16, and the angle adjustment limit component cooperates with the worm gear 25;

[0048] A multi-functional switching component is located at the bottom of the second joint block 24.

[0049] like Figures 2 to 4 As shown, the quick-release assembly includes:

[0050] Multiple sets of pin holes 4 are opened on the side wall of the connecting seat 3 and are evenly distributed in a circular array. Pin rods 5 are slidably connected to the inner wall of the pin holes 4. The end of the pin rod 5 away from the pin holes 4 is fixedly connected to the docking seat 7.

[0051] Slot 6 is formed on the outer wall of pin 5;

[0052] Multiple sets of strong springs 8 are provided, with one end of each strong spring fixedly connected to the inner wall of the connecting seat 3. The multiple sets of strong springs 8 are evenly distributed in a circular array on the side wall of the connecting seat 3. The extension direction of the strong springs 8 is the same as the radial direction of the connecting seat 3. The end of the strong spring 8 away from the inner wall of the connecting seat 3 is fixedly connected to a card plate 9 that engages with the card slot 6. A pressing rod 10 is fixedly connected to the side wall of the card plate 9. The axis of the pressing rod 10 is perpendicular to the side wall of the connecting seat 3.

[0053] Each plate 9 has two guide rods slidably connected to the side wall facing the strong spring 8. The two guide rods 11 are symmetrical with respect to the axis of the strong spring 8, and the other end of the two guide rods 11 is fixedly connected to the inner wall of the connecting seat 3.

[0054] like Figures 2 to 4 As shown, a drive plate 12 is rotatably connected to the inner wall of the connecting seat 3. Multiple sets of extrusion grooves 13 are evenly distributed in a circular array around the drive plate 12 on the side wall of the drive plate 12. The extrusion grooves 13 are sleeved on the outer wall of the extrusion rod 10. The extrusion grooves 13 are inclined. When the drive plate 12 is rotated, the extrusion rod 10 is extruded through the extrusion grooves 13 on the drive plate 12, which drives the clamping plate 9 to compress the strong spring 8 and disengage from the clamping slot 6. The pin 5 can then be pulled out to complete the quick-release assembly disassembly.

[0055] During assembly, the pin 5 connected to the docking seat 7 is inserted into the pin hole 4 of the connecting seat 3. After the pin 5 is in place, the strong spring 8 in the connecting seat 3 pushes the clamping plate 9 into the slot 6 of the pin 5, realizing the quick fixation of the docking seat 7 and the connecting seat 3. The guide rod 11 ensures the precise movement of the clamping plate 9. During disassembly, the drive plate 12 is rotated, and the extrusion groove 13 on the drive plate 12 extrudes the extrusion rod 10, which drives the clamping plate 9 to compress the strong spring 8 and disengage from the slot 6. The pin 5 can then be pulled out to complete the quick disassembly of the component.

[0056] like Figures 5 to 6 As shown, the angle adjustment limit component includes:

[0057] Side frame 17 is fixedly connected to the side wall of the first joint block 16;

[0058] The first drive motor 18 is fixedly connected to the side wall of the side frame 17, and the output end of the first drive motor 18 is fixedly connected to a worm gear 19. The worm gear 19 passes through the side frame 17, and the outer wall of the worm gear 19 meshes with the outer wall of the worm wheel 25. The surgeon issues an angle adjustment command through the touch screen 14 on the pistol grip 1, and the first drive motor 18 starts, driving the worm gear 19 on the side frame 17 to rotate. The worm gear 19 meshes with the worm wheel 25 on the outer wall of the rotating rod 21, driving the rotating rod 21 to rotate in the rotating seat 20. The rotating rod 21 synchronously drives the rotating block 22 to rotate, and then drives the lower multi-functional component to deflect through the second medical bracket 23 and the second joint block 24.

[0059] like Figures 8 to 10 As shown, the multi-functional switching component includes:

[0060] The medical housing 40 is fixedly connected to the bottom of the second joint block 24, and a second drive motor 28 is fixedly connected to the inner wall of the medical housing 40. The output end of the second drive motor 28 is fixedly connected to a drive gear 29 that is rotatably connected to the medical housing 40.

[0061] Multiple sets of vertically arranged screws 30 are rotatably connected to the inner bottom wall of the medical housing 40 and symmetrically distributed about the vertical direction of the medical housing 40. In this embodiment, there are two screws 30. A driven gear 31 that meshes with the drive gear 29 is fixedly connected to the top of the screw 30.

[0062] Multiple guide frames 32 are fixedly connected to the inner wall of the medical housing 40 and are symmetrically distributed about the vertical direction of the medical housing 40; in this embodiment, there are two guide frames 32.

[0063] The lifting block 33 is threaded to the outer wall of the screw 30, and a moving block 34 is slidably connected to the side wall of the lifting block 33. A driven rod 35 is fixedly connected to the side wall of the moving block 34. The axis of the driven rod 35 is perpendicular to the axis of the screw 30, and the driven rod 35 is located in the inner wall of the guide frame 32, passing through the lifting block 33. A touch screen 14 is fixedly connected to the side wall of the gun-type grip 1. The touch screen 14 is electrically connected to the first drive motor 18, the second drive motor 28, and the electric push rod 38. When the touch screen 14 issues a function switching command, the second drive motor 28 inside the medical housing 40 starts, driving the drive gear 29 to rotate. The drive gear 29 meshes with the driven gears 31 at the top of the screw 30, driving the screw 30 to rotate. The screw 30 drives the lifting block 33 threaded to the outer wall to move. The lifting block 33 drives the slidably connected moving block 34 and driven rod 35 to slide along the inner wall of the guide frame 32.

[0064] like Figures 8 to 10 As shown, a flexible frame 36 is fixedly connected to the bottom of the movable block 34, and a mounting plate 37 is fixedly connected to the bottom of the flexible frame 36. Different instruments with different functions can be installed on the mounting plate 37 to target different surgical procedures.

[0065] An electric push rod 38 is fixedly connected to the inner wall of the medical housing 40. A blunt dissecting forceps 39 is fixedly connected to the inner wall of the medical housing 40. One of the handles of the blunt dissecting forceps 39 is fixedly connected to the output end of the electric push rod 38. By extending and retracting the electric push rod 38, the handle of the blunt dissecting forceps 39 is moved to achieve tissue separation and gripping.

[0066] The bottom end of the flexible frame 36 penetrates the bottom wall of the medical housing 40. The driven rod 35 and the flexible frame 36 drive the mounting plate 37 to move, so as to realize the switching and alignment of different functional instruments on the mounting plate 37. Different component instruments are installed on different mounting plates 37, and the microprocessor is also installed on the mounting plate 37. When switching to the bipolar coagulation function, the bipolar electrode plates on the mounting plate 37, under the control of the microprocessor, use pulsed energy to progressively compress and coagulate the clamped tissue, monitoring the tissue impedance in real time until the coagulation impedance plateau is reached. This is existing technology and will not be elaborated here. When switching to the high-frequency cutting function, the system determines the completion of coagulation through impedance feedback and preset time. The ultra-thin high-frequency vibrating cutting wire on the mounting plate 37 cuts the coagulated tissue with high-speed micro-amplitude vibration between the bipolar electrodes. The electrodes simultaneously assist in hemostasis. After cutting, the cutting wire automatically retracts. When switching to the blunt separation function, the touch display screen 14 controls the extension and retraction of the electric push rod 38, which drives the handle of the blunt separation forceps 39 to move, realizing tissue separation (existing technology, which will not be elaborated here). The high-temperature resistant and anti-adhesion coating of the entire working end can prevent tissue adhesion.

[0067] like Figure 5 As shown, a sealing shell 26 is fixedly connected to the top of the side frame 17. The sealing shell 26 is sleeved on the outer wall of the worm gear 25. The sealing shell 26 effectively protects the worm gear 25 and prevents it from being contaminated by dust and water.

[0068] like Figures 1 to 2 As shown, the side wall of the pistol grip 1 has multiple sets of grip grooves 2 that are linearly distributed along the edge of the pistol grip 1. A touch screen display 14 is fixedly connected to the side wall of the pistol grip 1, and the touch screen display 14 is electrically connected to the first drive motor 18, the second drive motor 28, and the electric push rod 38. The operator holds the pistol grip 1 through the grip grooves 2 and centrally completes the instrument replacement confirmation, angle adjustment, function switching, and operation control on the touch screen display 14 without the need for additional operation of other components.

[0069] like Figure 7 As shown, an angle sensor 27 is fixedly connected to the side wall of the rotating seat 20 on one side. The angle sensor 27 cooperates with the rotating rod 21 and is electrically connected to the touch screen 14. The angle sensor 27 monitors the rotation angle of the rotating rod 21 in real time and feeds it back to the touch screen 14 to realize the digital display of the angle.

[0070] The working process of the laparoscopic multifunctional controllable angle electric cutting and coagulation device provided by this invention is as follows:

[0071] During assembly, the pin 5 connected to the docking seat 7 is inserted into the pin hole 4 of the connecting seat 3. After the pin 5 is in place, the strong spring 8 inside the connecting seat 3 pushes the retaining plate 9 into the retaining groove 6 of the pin 5, realizing the quick fixation of the docking seat 7 and the connecting seat 3. The guide rod 11 ensures the precise movement of the retaining plate 9. During disassembly, the drive plate 12 is rotated, and the compression groove 13 on the drive plate 12 compresses the compression rod 10, causing the retaining plate 9 to compress the strong spring 8 and disengage from the retaining groove 6, so that the pin 5 can be pulled out to complete the disassembly of the execution component; the operator uses a gun-style grip. The touch screen 14 on handle 1 issues an angle adjustment command, the first drive motor 18 starts, driving the worm gear 19 on the side frame 17 to rotate. The worm gear 19 meshes with the worm wheel 25 on the outer wall of the rotating rod 21, driving the rotating rod 21 to rotate within the rotating seat 20. The rotating rod 21 synchronously drives the rotating block 22 to rotate, which in turn drives the lower multi-functional component to deflect through the second medical bracket 23 and the second joint block 24. The angle sensor 27 monitors the rotation angle of the rotating rod 21 in real time and feeds it back to the touch screen 14 to realize the digital angle. The touch screen 14 displays a function switching command, and the second drive motor 28 inside the medical housing 40 starts, driving the drive gear 29 to rotate. The drive gear 29 meshes with the driven gear 31 at the top of the multiple sets of screws 30, driving the screws 30 to rotate. The screws 30 drive the lifting block 33 connected to the threaded connection on the outer wall to move. The lifting block 33 drives the sliding block to move. The driven rod 35 on the moving block 34 slides along the inner wall of the guide frame 32. The driven rod 35 and the flexible frame 36 drive the mounting plate 37 to move, realizing the switching and alignment of different functional instruments on the mounting plate 37. The first drive motor 18, the second drive motor 28, and the electric push rod 38 are all electrically connected to the touch screen 14. The operator holds the gun-type handle 1 through the grip groove 2 and centrally completes the instrument replacement confirmation, angle adjustment, function switching and operation control on the touch screen 14 without the need for additional operation of other components.

[0072] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
