Description

Technical Field

[0001] This invention relates to the field of abdominal cavity technology, and more specifically to a laparoscope. Background Technology

[0002] Similar to an electronic gastroscope, a laparoscope is a medical device equipped with a miniature camera. Laparoscopic surgery is a surgical procedure performed using a laparoscope and related instruments. Laparoscopic surgery is a newly developed minimally invasive method and an inevitable trend in the future development of surgical techniques. With the rapid advancement of industrial manufacturing technology and the integration of related disciplines, a solid foundation has been laid for the development of new technologies and methods. Coupled with increasingly skilled surgeons, many previously open surgeries have been replaced by endoscopic procedures, greatly increasing surgical options.

[0003] During laparoscopic surgery, the laparoscope lens often fogs up. The hospital usually removes the laparoscope, wipes the lens, and then reinserts it. However, removing and reinserting the laparoscope is time-consuming and laborious. In addition, it is difficult to align the angle of the laparoscope with the original angle after reinsertion, which requires medical staff to spend time adjusting the angle of the laparoscope. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a laparoscope to solve the technical problem mentioned in the background art where the laparoscope needs to be removed from the body for defogging when it fogs up.

[0005] To solve this technical problem, the technical solution adopted by the present invention is as follows:

[0006] A laparoscope includes a laparoscope body, a housing, a drive mechanism, a pushing assembly, a transmission mechanism, a lifting assembly, a wiping block, a limiting assembly, and a sealing assembly;

[0007] The laparoscope body is disposed on the outer wall of the housing, the housing has a cavity inside, and a connecting hole is provided on the side near the laparoscope body;

[0008] The drive mechanism is rotatably disposed inside the housing, with one end located outside the housing;

[0009] The pushing component is slidably disposed within the housing, and the rotation of the driving component can drive the pushing component to slide.

[0010] The transmission mechanism is rotatably disposed within the housing and engages with the lifting assembly. When the pushing assembly slides away from the connecting hole, it can drive the transmission mechanism to rotate in one direction.

[0011] The wiping blocks are provided in multiple ways and are respectively placed on the lifting assembly. The side walls of the wiping blocks respectively abut against the inner wall of the housing. The lifting assembly is slidably disposed on the inner wall of the housing. The wiping blocks are also provided with snap-fit ​​grooves.

[0012] The inner wall of the housing is provided with a plurality of sliding grooves along its length, and the plurality of limiting components are slidably disposed in the sliding grooves and can spontaneously reset.

[0013] Sliding the pushing component toward the connecting hole allows it to engage with the wiping block; sliding the pushing component away from the connecting hole allows the transmission component to rotate and drive the lifting component to slide toward the top surface of the housing, causing the wiping block to press against and slide the limiting component, and allowing the wiping block to be placed on the top surface of the limiting component. Continuing to slide will allow the pushing component and the wiping block to engage.

[0014] The sealing assembly is slidably disposed on the inner wall of the housing and connected to the driving mechanism. Rotating the driving mechanism can cause the sealing assembly to close the communicating hole.

[0015] Furthermore, the driving mechanism includes a wheel assembly, a transmission belt, and a first gear assembly; the wheel assembly and the first gear assembly are rotatably disposed on the inner wall of the housing, the transmission belt tightly wraps around the wheel assembly and the first gear assembly, one end of the wheel assembly is located outside the housing, and the rotation of the first gear assembly can drive the sliding of the pushing assembly. It should be understood that the rotation of the wheel assembly can drive the first gear assembly to rotate via the transmission belt.

[0016] Furthermore, the rotating wheel assembly includes a rotating shaft and a drive turntable, and the first gear assembly includes a first gear body and a first rotating shaft; the rotating shaft and the first rotating shaft are respectively rotatably connected to the inner wall of the housing, the drive turntable is coaxially fixed on the rotating shaft, and a portion of the drive turntable protrudes outside the housing; the first gear body is coaxially fixed on the first rotating shaft, and the transmission belt tightly wraps around the rotating shaft and the first rotating shaft. Preferably, the central axes of the first rotating shaft and the rotating shaft are located on the same vertical plane.

[0017] Furthermore, the pushing assembly includes a pushing block, a pushing rack, a locking connector, and a positioning plate; the pushing block is slidably connected to the inner wall of the housing, the top surface of the pushing block is provided with the pushing rack, and it meshes with the first gear body; the bottom surface of the pushing block is also provided with the pushing rack, and it meshes with the transmission assembly; the side of the pushing block is provided with a positioning plate, the lifting assembly can abut against the positioning plate, and restrict the positioning plate from continuing to move towards the communicating hole; the other side of the pushing block is provided with a locking connector, and the locking connector can engage with the rubbing block.

[0018] Furthermore, the transmission mechanism includes a second rotating shaft, a second gear body, a one-way component, a hollow gear, and a third rotating shaft; the second rotating shaft is rotatably connected to the inner wall of the housing, the second gear body and the one-way component are coaxially fixed to the second rotating shaft, and the second gear body meshes with the push rack located on the bottom surface of the push block; the third rotating shaft is rotatably connected to the inner wall of the housing and coaxial with the second rotating shaft, the hollow gear is coaxially disposed on the third rotating shaft, the hollow gear meshes with the lifting component, and the inner wall of the hollow gear is also provided with multiple ratchet teeth; the rotation of the one-way component can drive the hollow gear to rotate in one direction.

[0019] Furthermore, the one-way component includes a one-way turntable, a pawl, and a one-way spring; the one-way turntable is coaxially fixed on the second rotating shaft, the pawl is slidably connected to the one-way turntable radially along the one-way turntable, and is connected to the second rotating shaft through the one-way spring; the pawl can drive the ratchet to rotate in one direction.

[0020] Furthermore, the lifting assembly includes a lifting rack, a positioning baffle, a lifting rod, and a pressing rod; the lifting rack is slidably connected to the inner wall of the housing, the positioning baffle is fixed to the side wall of the lifting rack, and the positioning baffle can abut against and restrict the positioning plate from sliding toward the communicating hole; the lifting rod is fixed to the other side of the lifting rack, and the lifting rod can abut against and lift the rubbing block; the pressing rod is fixed to the side of the lifting rod, and can press the snap-fit ​​connector as the pressing rod is lifted, thereby releasing the snap-fit ​​state of the snap-fit ​​connector, and the pressing rod can pass through the rubbing block.

[0021] Furthermore, the limiting component includes a limiting plate and a limiting spring; the limiting plate is slidably connected in the slide groove and connected to the slide groove through the limiting spring; lifting the rubbing block can squeeze and slide the limiting plate.

[0022] Furthermore, the sealing assembly includes a sealing plate and a connecting rope; the sealing plate is slidably connected to the inner wall of the housing and connected to the rotating shaft through the connecting rope, and the sealing plate can close the communicating hole.

[0023] As can be seen from the above, rotating the drive mechanism allows the pushing component to move closer to or away from the connecting hole. Since the transmission mechanism is unidirectional, it can be set so that when the pushing component moves closer to the connecting hole, the transmission component does not drive the lifting component to slide. When the transmission mechanism moves away from the connecting hole, it drives the lifting component to slide. Due to the lifting of the lifting component, the wiping block placed on it slides, causing the wiping block to press the limiting component and slide into the groove. When the wiping block passes through the top surface of the wiping block, the limiting component automatically resets. At this time, moving the lifting component down allows the wiping block to be placed on the limiting component. Continuing to slide the pushing component causes it to engage with the wiping block, allowing the pushing component to push the wiping block out of the connecting hole, so that the wiping block can wipe and defog the fogged laparoscope body. When the wiping block is retracted, the lifting component will release the engagement between the pushing component and the wiping block. The next wiping block will push the previous insert block onto the limiting component closer to the top surface of the housing and can be placed on the limiting component parallel to the bottom surface of the pushing component. Therefore, by pushing the component to slide, the wiping block can be replaced, avoiding the problem of the previous wiping block being contaminated during the wiping process and affecting the next wiping.

[0041] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0042] Please refer to the following: Figures 1-6 The present invention provides a laparoscope, including a laparoscope body 1, a housing 2, a drive mechanism 3, a pushing component 4, a transmission mechanism 5, a lifting component 6, a wiping block 7, a limiting component 8, and a sealing component 9.

[0043] The laparoscope body 1 is located on the outer wall of the housing 2. The housing 2 has a cavity inside and a connecting hole 21 on the side near the laparoscope body 1. It should be understood that the bottom surface of the housing 2 is the insertion surface, and the connecting hole 21 is directly opposite the laparoscope's camera. In addition, the cavity inside the housing 2 can be roughly divided into left and right parts, separated by two plates with a gap between them. The gap is large enough to allow the pushing component 4 to pass through. The sides of the wiping block 7 abut against the inner wall of the housing 2 and the two plates respectively, making it difficult for the wiping block 7 to sway left and right when raised.

[0044] The drive mechanism 3 is rotatably disposed inside the housing 2, with one end located outside the housing 2.

[0045] In other embodiments, the drive mechanism 3 includes a wheel assembly 31, a transmission belt 32, and a first gear assembly 33. The wheel assembly 31 and the first gear assembly 33 are rotatably mounted on the inner wall of the housing 2. The transmission belt 32 tightly wraps around the wheel assembly 31 and the first gear assembly 33. One end of the wheel assembly 31 is located outside the housing 2. The rotation of the first gear assembly 33 can drive the sliding of the push assembly 4. It should be understood that the rotation of the wheel assembly 31 can drive the first gear assembly 33 to rotate via the transmission belt 32.

[0046] In other embodiments, the wheel assembly 31 includes a rotating shaft 311 and a drive turntable 312, and the first gear assembly 33 includes a first gear body 331 and a first rotating shaft 332; the rotating shaft 311 and the first rotating shaft 332 are rotatably connected to the inner wall of the housing 2, the drive turntable 312 is coaxially fixed on the rotating shaft, and a portion of the drive turntable 312 protrudes outside the housing 2; the first gear body 331 is coaxially fixed on the first rotating shaft 332, and the transmission belt 32 tightly wraps around the rotating shaft 311 and the first rotating shaft 332. Preferably, the central axes of the first rotating shaft 332 and the rotating shaft 311 are located on the same vertical plane.

[0047] The push component 4 is slidably disposed inside the housing 2, and the rotation of the drive component can drive the push component 4 to slide.

[0048] In other embodiments, the pushing assembly 4 includes a pushing block 41, a pushing rack 42, a locking connector 43, and a positioning plate 44. The pushing block 41 is slidably connected to the inner wall of the housing 2. The top surface of the pushing block 41 is provided with a pushing rack 42, which meshes with the first gear body 331. The bottom surface of the pushing block 41 is also provided with a pushing rack 42, which meshes with the transmission assembly. The side of the pushing block 41 is provided with a positioning plate 44, and the lifting assembly 6 can abut against the positioning plate 44 and restrict the positioning plate 44 from continuing to move towards the connecting hole 21. The other side of the pushing block 41 is provided with a locking connector 43, which can engage with the wiping block 7. It should be understood that one side of the pushing block 41 is slidably connected to the inner wall of the housing 2, and the opposite side is close to the transmission mechanism 5. The range of motion of the pushing block 41 is the distance between the pushing block 41 abutting against the inner wall of the housing 2 and the positioning plate 44 abutting against the lifting assembly 6. It should also be understood that when the pushing block 41 slides and is ready to engage with the wiping block 7, the sealing assembly 9 is still in the state of closing the connecting hole 21.

[0049] The transmission mechanism 5 is rotatably disposed inside the housing 2 and engages with the lifting component 6. When the pushing component 4 slides away from the connecting hole 21, it can drive the transmission mechanism 5 to rotate in one direction.

[0050] In other embodiments, the transmission mechanism 5 includes a second rotating shaft 51, a second gear body 52, a one-way component 53, a hollow gear 54, and a third rotating shaft 55. The second rotating shaft 51 is rotatably connected to the inner wall of the housing 2. The second gear body 52 and the one-way component 53 are coaxially fixed to the second rotating shaft 51. The second gear body 52 meshes with the push rack 42 located on the bottom surface of the push block 41. The third rotating shaft 55 is rotatably connected to the inner wall of the housing 2 and is coaxial with the second rotating shaft 51. The hollow gear 54 is coaxially disposed on the third rotating shaft 55 and meshes with the lifting component 6. The inner wall of the hollow gear 54 is also provided with multiple ratchet teeth 56. The rotation of the one-way component 53 can drive the hollow gear 54 to rotate in one direction. It should be understood that the second rotating shaft 51 and the third rotating shaft 55 are rotatably connected to the two opposite inner walls of the housing 2, and the third rotating shaft 55 is an L-shaped rod, one end of which is fixed to the inner wall of the hollow gear 54 and is spaced apart from the ratchet 56. In this embodiment, the sliding of the pushing block 41 toward the connecting hole 21 can drive the second rotating shaft 51 to rotate clockwise, but the one-way transmission of the one-way component 53 prevents the lifting component 6 from sliding; when the pushing block 41 slides away from the connecting hole 21, the second rotating shaft 51 reverses direction and causes the lifting component 6 to slide toward the top surface of the housing 2 through the one-way component 53. That is, the clockwise rotation of the second gear causes the one-way component 53 to slide past the ratchet 56 on the inner wall of the hollow gear 54 in sequence, while the counterclockwise rotation of the second rotating shaft 51 abuts against the ratchet 56 and drives the hollow gear 54 to rotate counterclockwise.

[0051] In other embodiments, the one-way component 53 includes a one-way turntable 531, a pawl 532, and a one-way spring 533. The one-way turntable 531 is coaxially fixed on the second rotating shaft 51. The pawl 532 is radially slidably connected to the one-way turntable 531 and connected to the second rotating shaft 51 via the one-way spring 533. The pawl 532 can drive the ratchet 56 to rotate in one direction. It should be understood that when the second rotating shaft 51 rotates clockwise, the pawl 532 slides along the side wall of the ratchet 56 and slides into the next ratchet 56 under the push of the one-way spring 533. During this process, the hollow gear 54 does not rotate. When the second rotating shaft 51 rotates counterclockwise, the pawl 532 abuts against the ratchet 56 and drives the ratchet 56 to rotate.

[0052] Multiple wiping blocks 7 are provided and are respectively placed on the lifting assembly 6. The side walls of the wiping blocks 7 abut against the inner wall of the housing 2. The lifting assembly 6 is slidably disposed on the inner wall of the housing 2. The wiping blocks 7 are also provided with locking grooves 71. It should be understood that the locking grooves 71 of the wiping blocks 7 are sideways "T"-shaped, and there is a protruding plate on one side wall. The lifting assembly 6 abuts against this plate to lift the wiping blocks 7. It should also be understood that the top surface of the wiping blocks 7 has a certain degree of flexibility and can wipe the camera of the laparoscopic body 1.

[0053] In other embodiments, the lifting assembly 6 includes a lifting rack 61, a positioning baffle 62, a lifting rod 63, and a pressing rod 64. The lifting rack is slidably connected to the inner wall of the housing 2. The positioning baffle 62 is fixed to the side wall of the lifting rack and can abut against and restrict the positioning plate 44 from sliding toward the connecting hole 21. The lifting rod 63 is fixed to the other side of the lifting rack and can abut against and lift the wiping block 7. The pressing rod 64 is fixed to the side of the lifting rod 63 and can press against the locking connector 43 as the pressing rod 64 is lifted, thereby releasing the locking state of the locking connector 43. The pressing rod 64 can pass through the wiping block 7. It should be understood that the lifting rod 63 is located above the pressing rod 64, and the lifting rod 63 abuts against the protruding flat bottom surface of the wiping block 7 and can lift the wiping block 7. Part of the pressing rod 64 is located within the vertical projection of the groove 22 of the wiping block 7 and can pass through the groove 22. When the pushing block 41 is not engaged with the wiping block 7, the pushing block 41 slides towards the connecting hole 21, and then slides away from the connecting hole 21, causing the lifting rack to rise. This, in turn, drives the wiping block 7 to rise via the lifting rod 63, until it presses against the limiting component 8 and finally moves onto the limiting component 8. At this point, the wiping block 7 can be placed on the limiting component 8. If there are other wiping blocks 7 above this wiping block 7, the pushing block 41 continues to slide away from the connecting hole 21, causing the wiping block 7 to push the wiping block above it so that it can be placed on another limiting component 8. Then, the drive turntable 312 is gradually released, and the lifting rack slides down under the action of gravity, allowing the wiping block 7 to be placed on the limiting component 8 parallel to the bottom surface of the pushing block 41. At this time, the sliding pushing block 41 slides towards the connecting hole 21, and the snap-fit ​​connector 43 can be snapped into the snap-fit ​​groove 71. When the wiping block 7 slides out of the connecting hole 21 and slides inward, the lifting block slides upward from the side of the pushing block 41, and as the wiping block 7 gradually slides inward, the pressing rod 64 gradually slides into the slide groove 22, pressing the snap-fit ​​connector 43 and finally sliding out of the slide groove 22. It should also be understood that the top surface of the wiping block 7 is provided with a groove, and when the next wiping block 7 pushes the previous wiping block 7, the limiting component 8 located above can be inserted into the groove.

[0054] The inner wall of the housing 2 is provided with multiple sliding grooves 22 along its length, and multiple limiting components 8 are slidably disposed in the sliding grooves 22 and can automatically reset.

[0055] In other embodiments, the limiting assembly 8 includes a limiting plate 81 and a limiting spring 82; the limiting plate 81 is slidably connected within the slide groove 22 and is connected to the slide groove 22 via the limiting spring 82; the lifting wiping block 7 can press and slide the limiting plate 81. It should be understood that the plane containing the bottom surface of the pushing block 41 is provided with multiple limiting plates 81, the wiping block 7 can be placed on the top surface of the limiting plate 81, and the sliding wiping block 7 will not fall off.

[0056] Sliding the push component 4 towards the connecting hole 21 allows it to engage with the wiping block 7. Sliding the push component 4 away from the connecting hole 21 causes the transmission component to rotate and drives the lifting component 6 to slide towards the top surface of the housing 2, causing the wiping block 7 to press against and slide the limiting component 8, and allowing the wiping block 7 to be placed on the top surface of the limiting component 8. Continuing to slide will allow the push component 4 and the wiping block 7 to engage.

[0057] The sealing component 9 is slidably disposed on the inner wall of the housing 2 and connected to the drive mechanism 3. Rotating the drive mechanism 3 can cause the sealing component 9 to close the connecting hole 21.

[0058] In other embodiments, the sealing assembly 9 includes a sealing plate 91 and a connecting rope 92. The sealing plate 91 is slidably connected to the inner wall of the housing 2 and connected to the rotating shaft 311 via the connecting rope 92. The sealing plate 91 can close the communicating hole 21. It should be understood that the connecting rope 92 is not taut at the beginning. It only becomes taut when the snap-fit ​​connector 43 is about to be inserted into the snap-fit ​​slot 71. When the snap-fit ​​connector 43 is inserted into the snap-fit ​​slot 71, the connecting rope 92 drives the sealing plate 91 to slide and open the communicating hole.

[0059] Rotating the drive mechanism 3 allows the pushing component 4 to move closer to or further away from the connecting hole 21. Since the transmission mechanism 5 operates in one direction, it can be configured so that when the pushing component 4 approaches the connecting hole 21, the transmission mechanism does not drive the lifting component 6 to slide; when the transmission mechanism 5 moves away from the connecting hole 21, it drives the lifting component 6 to slide. The lifting component 6's elevation causes the rubbing block 7 placed on it to slide, causing the rubbing block 7 to press against the limiting component 8 and slide into the groove 22. When the rubbing block 7 passes through its top surface, the limiting component 8... When the device automatically resets, the lowering and lifting component 6 allows the wiping block 7 to be placed on the limiting component 8. Continuing to slide and push the component 4, it engages with the wiping block 7, pushing it out of the connecting hole 21. This allows the wiping block 7 to wipe and defog the fogged laparoscope body 1. When the wiping block 7 is retracted, the lifting component 6 releases the engagement between the pushing component 4 and the wiping block 7. The next wiping block 7 pushes the previous block onto the limiting component 8, which is closer to the top surface of the housing 2, and can then be placed on the limiting component 8, which is parallel to the bottom surface of the pushing component 4. Thus, by sliding the pushing component 4, the wiping block 7 can be replaced, avoiding the problem of the previous wiping block 7 being contaminated during wiping and affecting the next wiping.

[0060] The above-mentioned laparoscope operation process is as follows: Initially, the push block 41 is pressed against the inner wall of the housing 2 away from the connecting hole 21, and the first rubbing block 7 is positioned below the bottom surface of the push block 41. The drive turntable 312 is rotated, causing the push block 41 to slide towards the connecting hole 21. The push rack 42 below drives the second gear body 52 to rotate, and at the same time drives the pawl 532 to rotate. Due to the unidirectional transmission characteristic of the transmission mechanism 5, the pawl 532 slides from one ratchet 56 to another ratchet 56, and does not drive the hollow gear 54 to rotate. The lifting component 6 and the rubbing block 7 do not move. When the push block 41 slides to a certain point, the connecting rope 92 becomes taut, and the connecting hole 2 is opened as the push block 41 continues to slide. 1. When the pushing block 41 moves to the point where the positioning plate 44 abuts against the positioning baffle 62, the pushing block 41 can no longer move towards the connecting hole 41. At this time, the reverse rotation of the drive turntable 312 causes the pushing block 41 to slide away from the connecting hole 21. At this time, the lower pushing rack 42 drives the second gear body 52 to rotate in the opposite direction, and at the same time drives the pawl 532 to rotate in the opposite direction. The pawl 532 abuts against the side wall of the ratchet 56 and drives the hollow gear 54 to rotate. The rotation of the hollow gear 54 drives the lifting rack 61 to slide upward. Since the lifting rod 63 abuts against the protruding part of the rubbing block 7, the rubbing block 7 is lifted upward until the rubbing block 7 causes the limiting plate 81 to slide into the slide groove 22 and then continues to lift until the rubbing block 7 can be placed. On the top surface of the limiting plate 81, the pushing block 41 can still slide away from the connecting hole 21, and the locking connector 43 and the wiping block 7 are at a distance. The pulling rope 92 is in the carding state. The pushing block 41 continues to slide towards the connecting hole 21. The connecting rope 92 gradually tightens and drives the sealing plate 91 away from the connecting hole 21. The wiping block 7 abuts against the sealing plate 91. After the locking connector 43 begins to enter the locking groove 71, the sealing plate 91 gradually slides. When it is locked in the locking groove 71, the connecting hole opens. Pushing the pushing block 41 causes the wiping block 7 to wipe the camera of the laparoscopic body 1. Due to the one-way transmission of the transmission mechanism 5, the lifting rod 63 does not change height. Then, the pushing block 41 slides backward, lifting the rack 6. 1. Slide upwards. Since the pushing block 41 abuts against the protruding part of the wiping block 7, when the wiping block 7 slides away, the lifting rod 63 lacks a stop and slides upwards. When the wiping block 7 slides inwards to a certain position, the squeezing rod 64 begins to enter the slide groove. When the wiping block 7 is completely inside the housing 2, the squeezing clamp 43 process is completed. Continue to slide the pushing block 41 inwards. This squeezing rod 64 continues to slide in the clamping groove 71 and eventually passes through. The next wiping block 7 is lifted by the next lifting rod 63 and pushes the previous wiping block 7 onto the higher limiting component 8.
