Description

Technical Field

[0001] This invention relates to the field of laparoscopic technology, and more particularly to a laparoscopic device for controllable release of hernia repair patches. Background Technology

[0002] Laparoscopy is an endoscope used for examination and treatment within the abdominal cavity. In essence, it is a fiber optic endoscope that includes a laparoscope, an energy system, a light source system, an irrigation system, and an imaging system. Many surgeries require the use of laparoscopy, such as hernia repair surgery, which requires the use of laparoscopy to observe the inside of the patient's abdominal cavity. In existing laparoscopic devices, the handgrip is held by the doctor, who moves the handgrip and optical endoscope to adjust the position of the endoscope inside the patient's body and observe the patient's condition from multiple angles. However, this method suffers from problems such as the inability to precisely move and adjust the optical endoscope's position within the patient, making it very inconvenient to use. Therefore, there is an urgent need for a laparoscopic device with controllable release of hernia repair patches. Summary of the Invention

[0003] Based on the technical problems in the background art, the present invention proposes a laparoscopic device for controllable release of hernia repair patches.

[0005] Preferably, the conveying mechanism further includes: a fixed ring, wherein multiple fixed rings are respectively fixedly sleeved on both ends of at least three planetary rods; an intermediate ring, wherein the intermediate ring is fixedly sleeved on the middle of the planetary rod; an external thread, wherein at least two external threads are respectively spirally wound and integrally formed and fixedly installed on both ends of the planetary rod; a threaded cylinder, wherein two threaded cylinders are respectively threadedly sleeved on both ends of the planetary rod; a prism ring, wherein two prism rings are movably sleeved on both ends of the planetary rod; and a movable sleeve, wherein one end of the movable sleeve is fixedly sleeved on the prism ring.

[0006] Preferably, the conveying mechanism further includes: a magnetic ring, which is fixedly disposed at the other end of the movable sleeve; a rubber ring, which is fixedly disposed on the side of the magnetic ring; an inner arc plate, which is movably arranged around the periphery of the planetary rod; an outer arc plate, which is fixedly disposed on the surface of the inner arc plate; and a metal strip, which is spirally arranged around the surface of the outer arc plate.

[0007] Preferably, the conveying mechanism further includes: a rubber strip, which is spirally wound around the surface of multiple outer arc plates; a spiral groove, which spirally wound around the surface of multiple outer arc plates; pin holes, which are opened in multiple inner arc plates; a spacer plate, which is movably disposed in the gaps between multiple inner arc plates; pin rods, which are fixedly disposed on both sides of the spacer plate; planetary plates, which are rotatably disposed at both ends of multiple planetary rods via a rotating component; and prisms, which are integrally formed and fixedly disposed at both ends of the planetary rods.

[0008] Preferably, the internal gear on the inner wall of the planetary cylinder simultaneously meshes with at least three ring gears, and the two pinions respectively mesh with the outer teeth of the two planetary cylinders. The diameter of the pinions is smaller than the diameter of the ring gears, and the at least three ring gears are arranged around the inner side of the planetary cylinder.

[0009] Preferably, the intermediate ring is located in the middle of the two external threads, the two external threads on both sides of the two intermediate rings have opposite helical directions, and the threaded cylinder is located between the fixed ring and the intermediate ring.

[0010] Preferably, the movable sleeve is movably sleeved around the fixed ring, the threaded cylinder is made of nickel alloy, one end of the threaded cylinder is provided with an inclined surface, and the inclined surface of one end of the threaded cylinder abuts against the middle of multiple inner arc plates.

[0011] Preferably, the length of the movable sleeve is greater than the movable distance of the threaded cylinder on the planetary rod, so that the rubber ring at the end of the movable sleeve can abut against the other end of the threaded cylinder. The two prism rings are located on the periphery of the two fixed rings respectively. The prism part is octagonal in shape, and the prism part is matched with the prism hole opened in the middle of the prism ring. The prism ring is movably sleeved on the prism part.

[0012] Preferably, both the inner and outer arc plates are arc-shaped, multiple inner arc plates form a ring, multiple outer arc plates form a ring, multiple outer arc plates are sleeved around the multiple inner arc plates, and the rubber strip is wrapped around the surface of the metal strip.

[0013] Preferably, the pin is inserted into the pin hole of the inner arc plate, multiple spacers are located in the gaps between the multiple inner arc plates, and the shape of the rubber strip matches the spiral groove, so that the metal strip and the rubber strip spirally surround the periphery of the multiple outer arc plates.

[0014] The beneficial effects of this invention are as follows: Multiple planetary rods surround the periphery of the optical endoscope, and multiple rubber strips spirally surround the periphery of the planetary rods. When the multiple rubber strips rotate synchronously, their surfaces rub against the optical endoscope, causing the optical endoscope to move. Because the multiple rubber strips are in close contact with the surface of the optical endoscope, the rotation angle of the multiple rubber strips is proportional to the moving distance of the optical endoscope. By precisely adjusting the rotation angle of the rubber strips, the movement of the optical endoscope can be precisely controlled, providing the advantage of precise optical endoscope movement. The threaded cylinders move at the ends of the planetary rods, and the two threaded cylinders synchronously open the multiple inner arc plates, ensuring that the multiple outer arc plates are opened synchronously. The metal strip moves in the spiral grooves on the surface of the multiple outer arc plates as they are opened. The rubber strips can be opened by the multiple outer arc plates, increasing the normal pressure of the rubber strips on the surface of the optical endoscope. The increased friction between the rubber strip surface and the optical endoscope surface enhances the accuracy of the optical endoscope movement when multiple rubber strips move it, providing the advantage of precise optical endoscope movement. The prism ring can move around the periphery of the prism section, and the shape of the prism section matches the prism hole in the center of the prism ring, allowing the planetary rod, prism section, movable sleeve, magnetic ring, rubber ring, and prism ring to rotate synchronously. The magnetic force between the magnetic ring and the threaded cylinder ensures that the rubber ring always abuts against the end of the threaded cylinder, guaranteeing synchronous rotation of the planetary rod, prism section, and threaded cylinder. This prevents the threaded cylinder from moving during planetary rod rotation, ensuring its positioning at the end of the planetary rod. The threaded cylinder is stably supported in the middle of multiple inner arc plates, ensuring the positive pressure of the rubber strips on the optical endoscope surface, thus guaranteeing the advantage of precise optical endoscope movement.

[0017] Reference Figures 1 to 10 A laparoscopic device for controllable release of hernia repair patches includes: a hand grip 1, which is internally equipped with components such as control switches. The control switches are connected to the servo motor 32 via wires. The control switches and other components can be purchased on the market or custom-made.

[0018] In this invention, the conveying mechanism includes: a drive frame 3, one end of which is movably fitted onto an optical endoscope 2, the optical endoscope 2 movably passing through the drive frame 3, two planetary plates 329, and a sealing plate 31, etc., the two planetary plates 329 limiting the optical endoscope 2 to prevent the optical endoscope 2 from contacting the ring gear 310; a sealing plate 31, which is fixedly disposed on the inner wall of the other end of the drive frame 3, sealing the other end of the drive frame 3; a servo motor 32, which is fixedly disposed on the inner wall of one end of the drive frame 3 by a support rod, the servo motor 32 can be obtained by purchasing from the market or by private customization; and multiple fixing plates 33, which are respectively fixedly disposed on the inner walls of both ends of the drive frame 3, and the multiple fixing plates 33 are respectively fixed around the inner wall of the drive frame 3.

[0019] In this invention, the active rod 34 has one end fixedly mounted on the power output end of the servo motor 32. After the servo motor 32 is connected to the power supply, its power output end drives the active rod 34 to rotate. The planetary cylinder 36 is rotatably mounted on multiple fixed plates 33 via a rotating component, which is a large bearing 35. The large bearing 35 is sleeved on the end of the planetary cylinder 36, and its surface is fixedly mounted on the side of the multiple fixed plates 33. The large bearing 35 is a ball bearing, which can be obtained by purchasing from the market or by private customization, so that the planetary cylinder 36 can be rotatably mounted in the middle of the multiple fixed plates 33.

[0020] In this invention, an internal gear 37 is integrally formed and fixedly disposed on the inner wall of a planetary cylinder 36. The internal gear 37 and a ring gear 310 mesh on the inner wall of the planetary cylinder 36. When the internal gear 37 and the planetary cylinder 36 rotate, they drive multiple ring gears 310 to rotate synchronously. A plurality of peripheral teeth 38 are integrally formed and fixedly disposed on the surface of the planetary cylinder 36. Two pinions 39 are respectively fixedly sleeved on both ends of a drive rod 34. The pinions 39 mesh with multiple peripheral teeth 38. At least three planetary rods 311 are movably disposed inside a drive frame 3. Multiple ring gears 310 are respectively fixedly sleeved on both ends of at least three planetary rods 311. The multiple ring gears 310 rotate synchronously, allowing at least three planetary rods 311 to rotate and revolve inside the drive frame 3.

[0021] In this invention, the conveying mechanism further includes: a fixed ring 312, wherein multiple fixed rings 312 are respectively fixedly sleeved on both ends of at least three planetary rods 311; an intermediate ring 313, wherein the intermediate ring 313 is fixedly sleeved on the middle of the planetary rods 311; an external thread 314, wherein at least two external threads 314 are respectively spirally wound and integrally formed and fixedly installed on both ends of the planetary rods 311; a threaded cylinder 315, wherein two threaded cylinders 315 are respectively threadedly sleeved on both ends of the planetary rods 311, and the rotation of the planetary rods 311 causes the threaded cylinders 315 to move along their axial direction; a prism ring 316, wherein two prism rings 316 are movably sleeved on both ends of the planetary rods 311, and the prism rings 316 slide at the ends of the planetary rods 311, so that the end of the movable sleeve 317 abuts against the end of the threaded cylinder 315; and a movable sleeve 317, one end of which is fixedly sleeved on the prism ring 316.

[0022] In this invention, the conveying mechanism further includes: a magnetic ring 318, which is fixedly disposed at the other end of the movable sleeve 317. The magnetic force between the magnetic ring 318 and the threaded cylinder 315 causes the magnetic ring 318 to approach the end of the threaded cylinder 315, and a rubber ring 319 to press against the end of the threaded cylinder 315, so that the threaded cylinder 315, the rubber ring 319, the prism ring 316, the planetary rod 311, and the movable sleeve 317 rotate synchronously; a rubber ring 319, which is fixedly disposed on the side of the magnetic ring 318; an inner arc plate 320, which is movably arranged around the periphery of the planetary rod 311; an outer arc plate 321, which is fixedly disposed on the surface of the inner arc plate 320; and a metal strip 323, which is spirally arranged around the surface of the outer arc plate 321, so that the surfaces of the outer arc plate 321 are gathered together.

[0023] In this invention, the conveying mechanism further includes: a rubber strip 324, which is spirally wound around the surface of multiple outer arc plates 321; and a spiral groove 325, which spirally wound around the opening of the multiple outer arc plates 321. The rubber strip 324 spirally wound in the spiral groove 325 of the multiple outer arc plates 321. The rubber strip 324 and the multiple outer arc plates 321 rotate synchronously. The rotation of the rubber strip 324 rubs against the optical endoscope 2, causing it to move along its axial direction, thereby driving the optical endoscope 2 to move among the multiple rubber strips 324. ; Pin holes 326, multiple pin holes 326 are set in the inner arc plate 320; partition plates 327, multiple partition plates 327 are movably arranged in the gaps of multiple inner arc plates 320; pin rods 328, multiple pin rods 328 are respectively fixedly set on both sides of the partition plate 327, and the pin rods 328 on both sides of the partition plate 327 are respectively inserted into the pin holes 326 of the two inner arc plates 320; planetary plates 329, two planetary plates 329 are rotatably set at both ends of multiple planetary rods 311 through a rotating component.

[0024] In this invention, the internal gear 37 on the inner wall of the planetary cylinder 36 is simultaneously engaged with at least three ring gears 310. When the planetary cylinder 36 and the internal gear 37 rotate, the internal gear 37 simultaneously drives at least three ring gears 310 to rotate synchronously on their own axis, and at the same time, at least three ring gears 310 revolve around the planetary cylinder. Two pinions 39 are respectively engaged with the outer teeth 38 on the outer periphery of the two planetary cylinders 36. The two pinions 39 respectively drive the two planetary cylinders 36 to rotate. The diameter of the pinions 39 is smaller than the diameter of the ring gears 310. At least three ring gears 310 are arranged around the inner side of the planetary cylinder 36.

[0025] In this invention, the intermediate ring 313 is located in the middle of the two external threads 314, and the two external threads 314 on both sides of the intermediate ring 313 have opposite helical directions. The threaded cylinder 315 is located between the fixed ring 312 and the intermediate ring 313. The planetary rod 311 and the two external threads 314 rotate synchronously, causing the threaded cylinders 315 at both ends of the planetary rod 311 to move in opposite directions along their axial direction, so that the two threaded cylinders 315 move closer to each other or further away from each other. When the two threaded cylinders 315 move closer to each other, they push the multiple inner arc plates 320 to separate synchronously, so that the rubber strips 324 on the surface of the multiple outer arc plates 321 are tightly attached to the surface of the optical endoscope 2.

[0026] In this invention, the movable sleeve 317 is movably fitted around the fixed ring 312. The threaded cylinder 315 is made of nickel alloy, and one end of the threaded cylinder 315 has a bevel. The bevel at one end of the threaded cylinder 315 abuts against the middle of multiple inner arc plates 320. The length of the movable sleeve 317 is greater than the movable distance of the threaded cylinder 315 on the planetary rod 311, so that the rubber ring 319 at the end of the movable sleeve 317 can abut against the other end of the threaded cylinder 315. Two prism rings 316 are respectively located around the two fixed rings 312. The prism portion 330 is octagonal in shape, and the prism portion 330 matches the prism hole opened in the middle of the prism ring 316. The 6 is movably sleeved on the prism part 330, so that the prism ring 316, the prism part 330 and the planetary rod 311 rotate synchronously. The rubber ring 319 abuts against the end of the threaded cylinder 315. The friction between the threaded cylinder 315 and the rubber ring 319 fixes the threaded cylinder 315 to the rubber ring 319, preventing the threaded cylinder 315 from rotating at the end of the planetary rod 311. This allows the threaded cylinder 315 and the planetary rod 311 to rotate synchronously, preventing the threaded cylinder 31 from moving at its end when the planetary rod 311 rotates, preventing the inner walls of the multiple inner arc plates 320 from losing support, and ensuring that the rubber strip 324 on the surface of the outer arc plate 321 is always in close contact with the surface of the optical endoscope.

[0027] In this invention, both the inner arc plate 320 and the outer arc plate 321 are arc-shaped. Multiple inner arc plates 320 form a ring, and multiple outer arc plates 321 form a ring. Multiple outer arc plates 321 are sleeved around the periphery of multiple inner arc plates 320. A rubber strip 324 wraps around the surface of a metal strip 323. A pin 328 is inserted into the pin hole 326 of the inner arc plate 320. Multiple spacers 327 are located in the gaps between multiple inner arc plates 320. The shape of the rubber strip 324 matches the spiral groove 325, so that the metal strip 323 and the rubber strip 324 spirally surround the periphery of multiple outer arc plates 321.

[0028] In use, firstly, the servo motor 32 is connected to the power supply. The servo motor 32 is controlled by a control switch. The power output of the servo motor 32 drives the drive rod 34 to rotate clockwise or counterclockwise, causing the drive rod 34 and the two pinions 39 to rotate synchronously. The rotation of the two pinions 39 drives the two planetary cylinders 36 to rotate, causing the two planetary cylinders 36, the two internal gears 37, and the two peripheral gears 38 to rotate synchronously. The peripheral gears 38 on the inner wall of the two planetary cylinders 36 drive multiple ring gears 310 to rotate synchronously, causing multiple planetary rods to rotate synchronously. While rotating on their own axis, planetary gear 311 and ring gear 310 also revolve around the center of the orbit. The planetary gear 311, inner arc plate 320, outer arc plate 321 and rubber strip 324 rotate synchronously. Multiple rubber strips 324 rotate on their own axis while revolving around the surface of the optical endoscope 2. The rubber strips 324 rotate synchronously and rub against the surface of the optical endoscope 2. The friction of the rubber strips 324 against the surface of the optical endoscope 2 drives it to move. This can transport the optical endoscope 2 to move in the middle of the drive frame 3 and complete the position adjustment of the optical endoscope 2. During adjustment, the optical endoscope 2 can be inserted through the drive frame 3 and the sealing plate 31, and inserted between the two planetary plates 329. Simultaneously, the optical endoscope 2 is inserted between at least three planetary rods 311. Then, push the movable sleeves 317 at both ends of one of the planetary rods 311 with both hands to move them, so that the rubber rings 319 at the ends of the movable sleeves 317 move away from the threaded cylinders 315. Next, rotate both threaded cylinders 315 by hand simultaneously. The two threaded cylinders 315 move at the ends of the planetary rods 311 respectively, and move between multiple inner arc plates 320. The textured cylinder 315 pushes multiple inner arc plates 320 to separate synchronously. The pin rod 328 moves in the pin hole 326 of the inner arc plate 320, causing multiple inner arc plates 320 and multiple outer arc plates 321 to separate synchronously. The multiple outer arc plates 321 separate and spread the metal strip 323 and rubber strip 324. Adjust the diameter of the rubber strip 324. According to the above operation, adjust the spreading position of multiple outer arc plates 321 around the other multiple planetary rods 311, so that the surface of multiple rubber strips 324 is in close contact with the surface of the optical endoscope 2. The multiple rubber strips 324 clamp the optical endoscope 2 to complete the fixation work.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
