Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] As described in the background section, during endoscopic foreign body removal, there is a risk of scraping or damaging the cavity wall if the retrieved foreign body is irregularly shaped or has sharp edges, or during passage through a curved body cavity or withdrawal of the endoscope. Such situations may not only cause additional tissue damage to the patient or animal, but may also affect the clinical treatment outcome.

[0047] Based on this, please refer to Figures 1-10 The present invention provides an endoscope assembly 100 and an endoscope 1000, which can effectively improve the aforementioned technical problems. Specifically, it can reduce the occurrence of scratching or damage to the inner wall of the cavity during foreign body removal, thereby improving the clinical treatment effect. The endoscope assembly 100 and the endoscope 1000 will be described in detail below.

[0048] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the endoscope 1000 provided in this embodiment. Figure 2 for Figure 1 A magnified view of a portion at point A. (Combined with...) Figure 1 and Figure 2 The endoscope 1000 includes an endoscope assembly 100, a tip 200, an insertion tube 300, and a handle 400. The tip 200, the insertion tube 300, and the handle 400 are connected in sequence, and the endoscope assembly 100 is sleeved on the distal end of the tip 200 and the insertion tube 300; the endoscope assembly 100 is used for foreign body aspiration.

[0049] Understandably, during the foreign body removal operation, the handle 400 is used to operate the insertion tube 300 and the tip 200 to enter the cavity. The tip 200 is used to identify the exact location of the foreign body. Then, the endoscope assembly 100 sucks up the foreign body and withdraws the endoscope along with the tip 200 and the insertion tube 300, thereby removing the foreign body.

[0050] For details, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the endoscope assembly 100 provided in this embodiment. Figure 4 This is an exploded view of the endoscope assembly 100 provided in this embodiment. (Combined with...) Figures 1-4 The endoscope assembly 100 includes a protective sleeve 110, a magnetic element 50, and a traction structure 60. The magnetic element 50 is disposed on the protective sleeve 110 and is slidably engaged with it. The traction structure 60 is connected to the magnetic element 50 and is used to pull the magnetic element 50 relative to the protective sleeve 110, allowing the magnetic element 50 to extend from or be housed within the protective sleeve 110. It should be noted that the length of the endoscope assembly 100 can be shorter than or similar to the length of the insertion tube 300.

[0051] In this embodiment, both the distal end and the tip 200 of the insertion tube 300 are located within the protective sleeve 110. It is easy to understand that during foreign body removal, the tip 200, located within the protective sleeve 110, is first used to identify the precise location of the foreign body. Then, the traction structure 60 drives the magnetic component 50 to extend from within the protective sleeve 110 to magnetically attract the foreign body. The magnetic component 50 is then retracted back into the protective sleeve 110, thus bringing the foreign body into place within the sleeve. In this way, the protective sleeve 110 effectively prevents the foreign body from contacting the inner wall of the cavity, thereby reducing the risk of scratching or damaging the inner wall of the cavity during foreign body removal and improving the effectiveness of clinical treatment.

[0052] It should be noted that the foreign objects mentioned above can be understood as ferromagnetic metal foreign objects such as nails, iron pieces, and stents that exist inside the human body during medical surgery.

[0053] Please refer to Figure 5 , Figure 5 This is a structural schematic diagram of the protective sleeve 110 provided in this embodiment, combined with... Figures 1-5The protective sleeve 110 includes an outer sleeve 10, a fixing seat 20, and an inner sleeve 30. The fixing seat 20 is disposed inside the outer sleeve 10 and connected to the inner wall of the outer sleeve 10. The inner sleeve 30 is connected to the fixing seat 20 and is spaced apart from the inner wall of the outer sleeve 10. A foreign matter receiving groove 40 is formed between the inner sleeve 30, the fixing seat 20, and the outer sleeve 10. A magnetic component 50 is slidably engaged with the inner sleeve 30 and is located in the foreign matter receiving groove 40. One end of a traction structure 60 passes through the fixing seat 20 and is connected to the magnetic component 50. The traction structure 60 is used to pull the magnetic component 50 to slide relative to the inner sleeve 30, so that the magnetic component 50 extends out of the foreign matter receiving groove 40 or is accommodated in the foreign matter receiving groove 40.

[0054] Specifically, in this embodiment, the insertion tube 300 is sequentially inserted through the outer sleeve 10 and the fixing base 20, with both the distal end and the tip 200 of the insertion tube 300 located within the inner sleeve 30. It is easy to understand that during foreign body removal, the tip 200 located within the inner sleeve 30 is first used to identify the precise location of the foreign body. Then, the traction structure 60 drives the magnetic component 50 to extend from the foreign body receiving groove 40 to magnetically attract the foreign body. The magnetic component 50 is then retracted into the foreign body receiving groove 40, thus placing the foreign body within it. In other words, the outer sleeve 10 effectively prevents the foreign body from contacting the inner wall of the cavity, thereby reducing the risk of scratching or damaging the inner wall of the cavity during foreign body removal and improving the effectiveness of clinical treatment.

[0055] Further, please refer to Figure 6 , Figure 6 This is a schematic diagram of the traction structure 60 provided in this embodiment, combined with... Figures 3-6 The traction structure 60 includes a traction wire 61 and an elastic element 62. The traction wire 61 passes through the fixed base 20 and is connected to the magnetic element 50. The elastic element 62 is sleeved on the traction wire 61, and both ends of the elastic element 62 are connected to the fixed base 20 and the magnetic element 50, respectively.

[0056] Understandably, before foreign object suction, the traction wire 61 can be pulled to place the magnetic component 50 into the foreign object receiving groove 40, and the elastic component 62 can be compressed to cause elastic deformation. In this way, when foreign objects need to be suctioned, the traction wire 61 can be released, and the magnetic component 50 will extend out of the foreign object receiving groove 40 under the action of the elastic force of the elastic component 62, which is convenient for magnetic suction of foreign objects, easy to operate, and can improve the suction efficiency of foreign objects.

[0057] To improve the stability of the traction magnetic component 50 during the traction process, the number of traction structures 60 can be multiple. For example, in this embodiment, the number of traction structures 60 is specifically two; of course, in other embodiments, the number of traction structures 60 can also be one, three, or four, etc.

[0058] Please continue to combine Figure 1 and Figure 4 and Figure 6 To facilitate control of the traction structure 60 to move the magnetic component 50, the endoscope 1000 also includes a traction controller 500, which is located on the handle 400 and connected to the traction structure 60. In this embodiment, the traction controller 500 is connected to the traction wire 61.

[0059] For details, please refer to Figure 7 , Figure 7 This is a structural schematic diagram of the traction controller 500 provided in this embodiment, combined with... Figure 1 , Figure 4 and Figure 7 The traction controller 500 includes a control box 501, a rotating shaft 502, a knob 503, and a fixing pin 504. The control box 501 is disposed on the handle 400, the rotating shaft 502 passes through the control box 501, the knob 503 is connected to one end of the rotating shaft 502, and the fixing pin 504 is disposed on the other end of the rotating shaft 502. The traction structure 60 passes through the control box 501 and is connected to the rotating shaft 502; specifically, in this embodiment, the rotating shaft 502 is connected to the traction wire 61.

[0060] In other words, before foreign object suction, the rotating shaft 502 is rotated by turning the knob 503, causing the traction wire 61 to wind around the rotating shaft 502. This moves the magnetic component 50 and places it into the foreign object receiving groove 40, while simultaneously compressing the elastic component 62. After the knob 503 is tightened, the rotating shaft 502 is fixed by the fixing pin 504, keeping the elastic component 62 in a deformed state and ensuring that the magnetic component 50 is stably fixed in the foreign object receiving groove 40. When it is necessary to suction the foreign object, the fixing pin 504 is removed, and the knob 503 is loosened, thereby releasing the traction wire 61. The magnetic component 50 will then extend from the foreign object receiving groove 40 under the elastic force of the elastic component 62, facilitating the magnetic suction of foreign objects. This convenient operation improves the efficiency of foreign object suction.

[0061] Please continue to combine Figure 4 To facilitate control of the magnetism of the magnetic component 50, the endoscope assembly 100 also includes an electromagnetic wire 70. One end of the electromagnetic wire 70 extends into the protective sleeve 110 and is connected to the magnetic component 50. Specifically, in this embodiment, one end of the electromagnetic wire 70 passes through the fixing base 20 and is connected to the magnetic component 50. That is, the electromagnetic wire 70 can be energized or de-energized to make the magnetic component 50 magnetic or non-magnetic.

[0062] Furthermore, combined Figure 1 and Figure 4In order to better control the on / off operation of the electromagnetic wire 70, the endoscope 1000 also includes an electromagnetic controller 600, which is located on the handle 400 and is used to connect to the electromagnetic wire 70 of the endoscope assembly 100.

[0063] As is easily understood, during foreign object removal, the electromagnetic controller 600 energizes the electromagnetic wire 70, making the magnetic component 50 magnetic, thus attracting the foreign object. When the endoscope 1000 is withdrawn from the cavity, the electromagnetic controller 600 de-energizes the electromagnetic wire 70, making the magnetic component 50 non-magnetic, thereby facilitating the removal of the foreign object from the magnetic component 50.

[0064] Please refer to Figure 8 , Figure 8 This is an assembly diagram of the traction controller 500 and the electromagnetic controller 600 provided in this embodiment, combined with... Figure 1 and Figure 8 In this embodiment, the electromagnetic controller 600 is specifically installed on the control box 501, that is, the electromagnetic controller 600 is assembled on the traction controller 500, which can save installation space and improve assembly efficiency; and it also makes it easier for operators to operate the traction controller 500 and the electromagnetic controller 600.

[0065] Please refer to Figure 9 and Figure 10 , Figure 9 This is a partial structural schematic diagram of the endoscope assembly 100 provided in this embodiment. Figure 10 This is a structural schematic diagram of the magnetic component 50 provided in this embodiment. (In conjunction with...) Figure 5 , Figure 9 and Figure 10 The magnetic component 50 has a first limiting groove 54 on the side near the fixed base 20, and the fixed base 20 has a second limiting groove 21 on the side near the magnetic component 50. The traction wire 61 passes through the second limiting groove 21 and is connected to the bottom wall of the first limiting groove 54. The traction structure 60 also includes a first limiting sleeve 63 and a second limiting sleeve 64. Both the first limiting sleeve 63 and the second limiting sleeve 64 are sleeved on the traction wire 61, with the first limiting sleeve 63 located in the first limiting groove 54 and the second limiting sleeve 64 located in the second limiting groove 21. The two ends of the elastic component 62 are respectively connected to the first limiting sleeve 63 and the second limiting sleeve 64.

[0066] By setting the first limiting sleeve 63 and the second limiting sleeve 64, the installation stability of the elastic element 62 can be improved; at the same time, by setting the first limiting sleeve 63 and the second limiting sleeve 64 in the first limiting groove 54 and the second limiting groove 21 respectively, the stability of the traction wire 61 during movement can be further improved.

[0067] Specifically, the magnetic component 50 is sleeved on the inner sleeve 30, and one of the magnetic component 50 and the inner sleeve 30 is provided with a sliding protrusion 31, while the other of the magnetic component 50 and the inner sleeve 30 is provided with a sliding groove 51. The sliding protrusion 31 is provided in the sliding groove 51, thereby realizing the sliding engagement between the magnetic component 50 and the inner sleeve 30.

[0068] It should be noted that in this embodiment, the inner wall of the magnetic component 50 is provided with a groove 51, while the outer wall of the inner sleeve 30 is provided with a sliding protrusion 31. Of course, in other embodiments, the inner wall of the magnetic component 50 may be provided with a sliding protrusion 31, and correspondingly, a groove 51 may be provided on the outer wall of the inner sleeve 30.

[0069] To improve the sliding stability between the magnetic component 50 and the inner sleeve 30, the number of sliding protrusions 31 and sliding grooves 51 can both be set to multiple. The multiple sliding protrusions 31 are spaced apart, and the multiple sliding grooves 51 are spaced apart, corresponding one-to-one with the multiple sliding protrusions 31. For example, in this embodiment, the number of sliding protrusions 31 and sliding grooves 51 are both four. The four sliding protrusions 31 are arranged circumferentially around the inner sleeve 30, and the four sliding grooves 51 are similarly arranged circumferentially around the inner peripheral wall of the magnetic component 50. Of course, in other embodiments, the number of sliding protrusions 31 and sliding grooves 51 can also be one, two, or three, etc.

[0070] Furthermore, the slide groove 51 includes a first slide groove 511 and a second slide groove 512 that are connected to each other. The magnetic component 50 includes a first cylindrical sliding part 52 and a second cylindrical sliding part 53 that are coaxially arranged. The first cylindrical sliding part 52 is connected to the second cylindrical sliding part 53 and is located on the side of the second cylindrical sliding part 53 away from the fixed base 20. The first cylindrical sliding part 52 and the second cylindrical sliding part 53 are both sleeved on the inner sleeve 30. The inner wall of the first cylindrical sliding part 52 is provided with the first slide groove 511, and the inner wall of the second cylindrical sliding part 53 is provided with the second slide groove 512. The sliding protrusion 31 is simultaneously provided in the first slide groove 511 and the second slide groove 512. The size of the first cylindrical sliding part 52 is smaller than the size of the second cylindrical sliding part 53, and the first cylindrical sliding part 52 is spaced apart from the inner wall of the outer sleeve 10. The second cylindrical sliding part 53 abuts against the inner wall of the outer sleeve 10. The traction structure 60 is connected to the second cylindrical sliding part 53.

[0071] Understandably, the first cylindrical sliding part 52 is a smaller cylindrical structure, which can increase the accommodating space of the foreign object receiving groove 40 to accommodate foreign objects of larger sizes. The second cylindrical sliding part 53 is a larger cylindrical structure, which can abut against the inner wall of the outer sleeve 10, thereby further improving the stability of the magnetic component 50 during the overall sliding process, and thus enhancing the stability during the foreign object suction process.

[0072] Based on the above description, the method for foreign body aspiration using the endoscope 1000 provided in this embodiment is as follows:

[0073] Preparation stage: First, fit the endoscope assembly 100 onto the tip 200 and the insertion tube 300, so that the distal ends of the tip 200 and the insertion tube 300 are both located inside the inner sleeve 30; then, install the traction controller 500 on the handle 400 and connect the traction wire 61 to the rotating shaft 502; next, install the electromagnetic controller 600 on the control box 501 and connect it to the electromagnetic wire 70.

[0074] During the insertion stage: Keep the end face of the tip 200 flush with the end face of the inner sleeve 30, and de-energize the electromagnetic wire 70 through the electromagnetic controller 600 to demagnetize the magnetic component 50; then insert the endoscope assembly 100, the tip 200 and the insertion tube 300 into the cavity.

[0075] Foreign body aspiration stage: After detecting the foreign body through the image captured by the tip 200, the angle of the endoscope 1000 is adjusted to approach the foreign body; the traction controller 500 is operated to release the traction wire 61, and the elastic force of the elastic element 62 is used to extend the magnetic element 50 from the foreign body receiving groove 40. Then, the electromagnetic controller 600 is operated to energize the electromagnetic wire 70, so that the magnetic element 50 becomes magnetic to attract the foreign body; then the traction controller 500 is operated again to retract the traction wire 61 and compress the elastic element 62, while simultaneously driving the magnetic element 50 and the foreign body back into the foreign body receiving groove 40. At this time, the fixing pin 504 can be used to lock the fixing shaft 502 to ensure that the magnetic element 50 and the foreign body are stably contained in the foreign body receiving groove 40; finally, the endoscope 1000 is controlled to withdraw from the cavity as a whole.

[0076] Foreign object removal stage: First, operate the traction controller 500 to release the traction wire 61, and use the elastic force of the elastic element 62 to extend the magnetic element 50 out of the foreign object receiving groove 40, and also extend the foreign object out of the foreign object receiving groove 40; then operate the electromagnetic controller 600 to de-energize the electromagnetic wire 70, so that the magnetic element 50 is demagnetized, and then remove the foreign object from the magnetic element 50.

[0077] In summary, embodiments of this utility model provide an endoscope assembly 100 and an endoscope 1000. The endoscope assembly 100 includes a protective sleeve 110, a magnetic element 50, and a traction structure 60. The magnetic element 50 is disposed in the protective sleeve 110 and is slidably engaged with the protective sleeve 110. The traction structure 60 is connected to the magnetic element 50 and is used to pull the magnetic element 50 relative to the protective sleeve 110 so that the magnetic element 50 extends out of the protective sleeve 110 or is contained within the protective sleeve 110. During foreign body removal, the traction structure 60 pulls the magnetic element 50 out of the protective sleeve 110 to magnetically attract the foreign body, and then pulls the magnetic element 50 back into the protective sleeve 110, so that the foreign body is also brought into the protective sleeve 110. In this way, the protective sleeve 110 can prevent the foreign body from contacting the inner wall of the cavity, thereby reducing the possibility of scratching or damaging the inner wall of the cavity during foreign body removal and improving the clinical treatment effect.
