Description

Technical Field

[0001] This invention relates to the field of laparoscopic technology, specifically to a laparoscopic assist device. Background Technology

[0002] Laparoscopic surgery has been widely used in clinical practice due to its advantages such as minimal trauma and rapid recovery. During the operation, a specialist must hold the laparoscope and continuously maintain its stability to ensure a clear field of vision. Currently, clinical practice often uses manual laparoscope holding or simple support to assist in holding the laparoscope. Manual laparoscope holding is prone to image shaking due to fatigue or arm tremors of medical staff, affecting the accuracy of the operation. While simple support can reduce physical burden, it lacks flexibility in height and angle adjustment and has poor adaptability.

[0003] Currently, laparoscopic surgery requires the entire instrument to be replaced if the lens becomes contaminated, resulting in the need to carry a large number of spare laparoscopic rods during the operation. This not only leads to low instrument utilization but also causes frequent disassembly and replacement, cumbersome operation, long interruption time in the operation, and affects the continuity of the operation.

[0004] To address the above issues, a laparoscopic assist device is proposed. Summary of the Invention

[0020] 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 embodiments of the present invention, and not all embodiments. Based on the 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.

[0021] To address the technical problem of obstructed vision due to contamination of the laparoscopic telescope during surgery, leaving no time for cleaning, such as... Figure 1 and Figure 2 As shown, the following preferred technical solution is provided: a laparoscopic assist device, including a movable structure 1, a cleaning structure 2 fixedly installed on the top of the movable structure 1, a positioning structure 3 rotatably connected to the top of the cleaning structure 2, a support structure 4 fixedly installed on the top of the positioning structure 3, a support frame 5 rotatably connected to the top of the support structure 4, an operating table 6 fixedly installed on the side wall of the support frame 5, an original laparoscopic rod 9 provided in the inner cavity of the support frame 5, and the outer wall of the original laparoscopic rod 9 may be made of iron, a laparoscopic handle 7 is snapped onto one end of the original laparoscopic rod 9, and a spare laparoscopic rod 8 is provided in the inner cavity of the positioning structure 3.

[0022] Specifically, when using this auxiliary device, first fix the auxiliary device to the bed railing, insert the moving structure 1 horizontally from above into the railing and tighten it to achieve positioning, then place the original laparoscope rod 9 at one end of the laparoscopic handle 7 into the inner cavity of the support frame 5, and support the original laparoscope rod 9 through the support frame 5 to reduce the force required for medical staff to maintain support. The height of the support frame 5 can also be adjusted by adjusting the support structure 4, and then the support structure 4 can be extended and fixed to adjust the height of the support frame 5 so that the laparoscopic handle 7 can adapt to different height requirements. The position of the laparoscopic handle 7 can be adjusted in conjunction with the mobility of the moving structure 1, so that medical staff can maintain the stability of the laparoscopic handle 7 and the original laparoscope rod 9 for a long time.

[0023] Furthermore, if the original laparoscope rod 9 becomes contaminated during use, obstructing the view of the miniature camera, medical staff can remove the original laparoscope rod 9 from the patient's body. Then, the medical staff vertically place the original laparoscope rod 9 and the laparoscope handle 7 into the collection module of the positioning structure 3. During this process, the original laparoscope rod 9 slides downward in the inner cavity of the support frame 5. Then, press the disassembly pressing part of the laparoscope handle 7 and the original laparoscope rod 9 to separate them. The medical staff can then hold the laparoscope handle 7 and insert it again into the top of the spare laparoscope rod 8, locking it into the inner cavity of the laparoscope handle 7, thus completing the assembly of the laparoscope handle 7 and allowing it to be reused in the surgery.

[0024] The remaining original laparoscope rod 9 can be used by medical staff to activate the drive mechanism in the cleaning structure 2 via the operating table 6. This allows the original laparoscope rod 9 to enter the inner cavity of the cleaning structure 2. Once the original laparoscope rod 9 is inside the cleaning structure 2, the cleaning module of the cleaning structure 2 can be activated again via the operating table 6. This causes the cleaning module to spray water onto the miniature camera of the original laparoscope rod 9, thus achieving a cleaning effect and facilitating its reuse. Meanwhile, any remaining water falls into the inner cavity of the cleaning structure 2, to be cleaned again after the surgery.

[0025] To address the technical issue of image shakiness and reduced precision during surgery caused by manual scope manipulation due to staff fatigue and arm tremors, such as... Figure 1 - Figure 4As shown, the following preferred technical solution is provided: The movable structure 1 includes a fixed platform 16 fixedly installed at the bottom of the cleaning structure 2. A slide table 15 is fixedly installed at the bottom of the fixed platform 16. A slide rod 12 is slidably connected to the inner wall of the slide table 15. A transverse clamping plate 11 is fixedly installed at the bottom of the slide rod 12. A bolt 14 is threadedly connected to the side wall of the transverse clamping plate 11. One end of the bolt 14 is rotatably connected to a pressing plate 13, and the pressing plate 13 is located in the inner cavity of the transverse clamping plate 11. The support structure 4 includes a support rod 41 fixedly installed at the top of the positioning structure 3. A support telescopic tube 42 is fixedly installed at the top of the support rod 41. The inner cavity at the top of the support telescopic tube 42 is slidably connected to... An extension rod 44 is attached, and a No. 2 bolt 43 is threadedly connected to the inner wall of the telescopic tube 42. The support frame 5 includes a fixed frame 51 rotatably connected to the top of the extension rod 44. A steering tube 53 is rotatably connected to the side wall of the fixed frame 51. A placement plate 52 is fixedly installed at one end of the steering tube 53. A movable groove 54 is opened in the inner cavity of the placement plate 52. A plastic rod 55 is rotatably connected to the inner wall of the movable groove 54. A magnetic ring 56 is rotatably connected to the outer wall of the plastic rod 55. An anti-slip sleeve 57 is fixedly installed on the outer wall of the magnetic ring 56. The magnetic ring 56 is rotatably connected to the outer wall of the original laparoscopic rod 9 by the magnetic force generated by the magnetic ring 56.

[0026] The laparoscopic handle 7 includes a connecting tube 74 that is inserted into one end of the original laparoscopic rod 9. One end of the connecting tube 74 is fixedly installed on the handle housing 71. The top of the handle housing 71 is provided with a laparoscopic disassembly button 72. The laparoscopic disassembly button 72 is existing technology. By pressing the laparoscopic disassembly button 72, the original laparoscopic rod 9 can be disengaged, thereby achieving the effect of quick disassembly of the original laparoscopic rod 9. A miniature camera data cable 75 is fixedly installed on the top of the handle housing 71. A handle 73 is rotatably connected to the inner wall of the handle housing 71.

[0027] Specifically, when using this auxiliary device, first fix the auxiliary device to the bed railing, insert the transverse clamp 11 horizontally from above into the railing, then rotate the No. 1 bolt 14 so that the outer wall of the No. 1 bolt 14 is threadedly connected to the outer wall of the transverse clamp 11, thereby pushing the compression plate 13 to press against the bed railing, thus tightening the transverse clamp 11. Then, place the original laparoscopic rod 9 at one end of the connecting tube 74 into the inner cavity of the placement plate 52, and support the original laparoscopic rod 9 through the fixing bracket 51, reducing the force required for medical staff to maintain support. The device can also be adjusted... The extension rod 44 adjusts the height of the fixing frame 51. By rotating the second bolt 43, the extension rod 44 loses the tightening effect of the second bolt 43. Then, the extension rod 44 is pulled to extend or retract into the inner cavity of the support telescopic tube 42. After the position is adjusted, the second bolt 43 is rotated again to tighten the outer wall of the extension rod 44, thereby achieving a fixed effect. This allows the laparoscopic handle 7 to adapt to different height requirements. Combined with the sliding table 15, it can slide on the sliding rod 12, making it convenient to adjust the position of the handle shell 71. This facilitates medical staff to maintain the stability of the handle shell 71 and the original laparoscopic rod 9 for a long time.

[0028] To address the technical problem of not having time to rinse and disinfect the contaminated laparoscopic rods after replacement, such as Figure 4 - Figure 9 As shown, the following preferred technical solution is provided: The positioning structure 3 includes a positioning platform 31 fixedly installed at the bottom of the support rod 41. Multiple positioning frames 32 are provided at the bottom of the positioning platform 31. A filter frame 33 is fixedly installed at the bottom of the positioning frame 32. A positioning magnet 34 is provided in the inner cavity at the bottom of the positioning frame 32. The cleaning structure 2 includes a connecting block 262 fixedly installed at the top of the fixed platform 16. A drive motor 26 is fixedly installed at the top of the connecting block 262. A square block 261 is fixedly installed at the output end of the drive motor 26. A lifting tube 28 is slidably connected to the outer wall of the square block 261, and the top of the lifting tube 28 is rotatably connected to the bottom of the positioning platform 31.

[0029] The inner cavity of the lifting tube 28 has a square groove 281. A push block 282 is fixedly installed on the outer wall of the bottom of the lifting tube 28. A first connecting frame 283 is fixedly installed on the inner side of the bottom of the push block 282. A telescopic rod 284 is rotatably connected to the inner cavity of the first connecting frame 283. A return spring 287 is movably sleeved on the outer wall of the telescopic rod 284. A second connecting frame 286 is rotatably connected to the bottom of the telescopic rod 284. A rotating plate 285 is fixedly installed on the bottom of the second connecting frame 286. The two sides of one end of the rotating plate 285 are rotatably connected to the inner side of the bottom of the push block 282. The outer wall of the drive motor 26 is rotatably connected to the inner tube 22 and is limited by the inner tube 22, so it cannot move up or down. Limit grooves 221 are opened on both sides of the outer wall of the inner tube 22. A limit rod 222 is fixedly installed on the top of the inner tube 22 and the limit rod 222 is located in the inner cavity of the positioning table 31. The inner tube 22 is slidably connected to a cleaning box 21 fixedly installed on its side wall. A fixing ring 27 is fixedly installed on the inner wall of the inner tube 22. An inclined triangular block 271 is fixedly connected to the inner wall of the top of the fixing ring 27. A threaded guide tube 23 is slidably connected to the inner cavity of the inner tube 22. Slider 231 is fixedly installed on both sides of the outer wall of the threaded guide tube 23. The slider 231 is slidably connected to the inner cavity of the limiting groove 221. A partition box 24 is placed in the inner cavity of the top of the cleaning box 21. A dustproof plastic film 241 is provided on the top of the partition box 24. A film inlet 242 is opened on the top of the dustproof plastic film 241. A plastic clamp 25 is inserted into the outer wall of the top of the cleaning box 21. Multiple limiting rings 252 are provided on the outer wall of the plastic clamp 25. A water guide pipe 251 is provided on the inner side of the limiting ring 252. A water spray nozzle 253 is fixedly installed at one end of the water guide pipe 251.

[0030] Specifically, if the original laparoscope rod 9 becomes contaminated during use, obstructing the view of the miniature camera, medical personnel can remove the original laparoscope rod 9 from the patient's body. Then, the medical personnel align the original laparoscope rod 9 and handle housing 71 vertically with the positioning frame 32. During this process, the original laparoscope rod 9 slides downwards within the inner cavity of the support frame 5 until its outer wall falls into the inner cavity of the positioning frame 32. The positioning magnet 34 magnetically attracts the outer wall of the original laparoscope rod 9. Then, pressing the laparoscope disassembly button 72 allows the handle housing 71 to be pulled out from the top of the original laparoscope rod 9, achieving separation. Medical personnel can then hold the handle housing 71 and align it with the top of the spare laparoscope rod 8, inserting it and locking it into the inner cavity of the laparoscope handle 7, thus completing the assembly of the laparoscope handle 7 and allowing it to be reintroduced into the surgery, achieving rapid replacement.

[0031] The replaced original laparoscope rod 9 can be driven by the medical staff through the operating table 6 by activating the drive mechanism in the drive motor 26. The top of the drive motor 26 drives the square block 261 to rotate clockwise, which in turn drives the lifting tube 28 to rotate. As the lifting tube 28 rotates, the push block 282 slides down along the groove on the outer wall of the threaded guide tube 23, and drives the support rod 41 to move downward until the rotating plate 285 at the bottom of the push block 282 descends to the upper surface of the fixing ring 27. At this moment, the original laparoscope rod 9 and the spare laparoscope rod 8 will pass through the membrane inlet 242 on the upper surface of the dustproof plastic film 241 and enter the... The inner cavity of the separator box 24 allows the separator box 24 to receive the water. At this moment, the water source connected to the water pipe 251 is activated again through the operating table 6. Water for disinfection and cleaning enters from the water pipe 251 and sprays out from the spray nozzle 253, thereby cleaning and disinfecting the miniature camera at the bottom of the original laparoscope rod 9. The remaining water will remain in the inner cavity of the separator box 24 for subsequent cleaning. After the original laparoscope rod 9 is cleaned, the drive motor 26 can be activated again to drive the square block 261 to rotate counterclockwise, so that the push block 282 enters the groove on the outer wall of the threaded guide tube 23 and slides, thereby driving the positioning structure 3 to rise and reset as a whole.

[0032] If the push block 282 is located on the upper surface of the fixed ring 27, the continued rotation of the square block 261 can push the side wall of the inclined triangular block 271 through the rotating plate 285, thereby driving the inner tube 22 to rotate. At the same time, the cleaning box 21 rotates synchronously, thereby driving the positioning frame 32, the filter frame 33 and the used separator box 24 to switch positions together, so that the unused separator box 24 can be used directly next time.
