AI Technical Summary

Technical Problem

The endoscope cable protective sleeve is easily damaged during the axial stretching of the cable, resulting in the inability to effectively protect the cable.

Method used

An endoscope cable protective sleeve is designed, adopting a combined structure of a cylindrical film and shrinking ribs. The cylindrical film is compressed and folded in the axial length. The shrinking ribs are arranged on the inner peripheral wall of the cylindrical film in the axial direction.

Description

Technical Field

[0001] The present application relates to the technical field of endoscopes, and in particular to an endoscope cable protective cover and an endoscope. Background Art

[0002] The endoscope handle is connected to the host through a cable to establish a passage, wherein the cable is detachably connected to the endoscope handle, that is, the cable is reusable.

[0003] Since the endoscope needs to enter different patients' bodies to observe lesions, during the observation process, pollutants (such as blood, body fluids, etc.) may splash onto the cables through splashing, dripping, etc., so the cables need to be disinfected and cleaned before they can be reused. Therefore, in order to protect the cables and reduce the cost of cleaning and disinfection, the relevant technology will put a protective cover on the cables when using the endoscope.

[0004] However, in actual operation, the plastic film in the protective cover needs to be unfolded for use. During the pulling process, the protective cover is easily torn due to the thinness of the plastic film itself, which makes it difficult for the protective cover to provide good protection for the cable. Summary of the invention

[0005] The present application provides an endoscope cable protective cover and an endoscope, which are at least used to solve the problem that the endoscope cable protective cover is easily damaged during the axial stretching process on the cable.

[0006] In the first aspect, an embodiment of the present application provides an endoscope cable protective cover, comprising: a cylindrical film, which is compressed and folded in the axial length; a contraction rib, which is axially arranged on the inner circumferential wall of the cylindrical film, and is compressed and folded in the axial length, and the contraction rib has multiple connection points with the cylindrical film in the axial direction, and the folding amount of the contraction rib between two adjacent connection points is smaller than the folding amount of the cylindrical film; one end of the cylindrical film is moved axially to drive the cylindrical film and the contraction rib to unfold, and the contraction rib is straightened before the cylindrical film.

[0007] In some embodiments of the present application, the endoscope cable protective cover also includes a cylinder, which includes a first cylinder and a second cylinder, and a accommodating cavity is provided between the first cylinder and the second cylinder; a connecting part, which can be disconnected by an external force, and the connecting part connects the first cylinder and the second cylinder; the cylindrical film is arranged in the accommodating cavity, one end of the cylindrical film is connected to the first cylinder, and the other end is connected to the second cylinder, and the second cylinder is moved axially to drive the cylindrical film and the contraction ribs to expand.

[0008] In some embodiments of the present application, the tubular film is folded in a zigzag shape in sequence in the axial direction, and the multiple connection points are located at the bottom of the tubular film.

[0009] In some embodiments of the present application, the second cylinder includes a first half cylinder and a second half cylinder, and the second cylinder is formed by connecting the first half cylinder and the second half cylinder. By pulling the first half cylinder and the second half cylinder with force, the second cylinder can be separated along the first connecting seam between the first half cylinder and the second half cylinder, and the cylindrical film can be torn open.

[0010] In some embodiments of the present application, the endoscope cable protective cover further includes a separation portion, which is axially arranged on the cylindrical film, and when the first semi-cylinder is separated from the second semi-cylinder, the cylindrical film is torn along the separation portion.

[0011] In some embodiments of the present application, the separation portion is a separation rib, and the separation rib is the same as the folding amount of the tubular film, and there are multiple separation ribs; the separation ribs are axially arranged on the inner circumferential wall and / or the outer circumferential wall of the tubular film corresponding to the first connecting seam; or, every two of the separation ribs constitute a group of separation ribs, and two of the separation ribs in the group of separation ribs are symmetrically arranged on the inner circumferential wall and / or the outer circumferential wall of the tubular film at both sides of the first connecting seam, and when the first half cylinder is separated from the second half cylinder, the tubular film is torn apart from between the two separation ribs in the group of separation ribs.

[0012] In some embodiments of the present application, the endoscope cable protective cover also includes at least one connecting portion, which is arranged at the first connecting seam to connect the first half cylinder and the second half cylinder. The connecting portion is pulled out, and based on the remaining gap after pulling out the connecting portion, the first half cylinder and the second half cylinder are separated along the first connecting seam.

[0013] In some embodiments of the present application, the endoscope cable protective cover further includes a rotating portion, which is sleeved on the outer peripheral wall of the second cylinder, and the rotating portion is connected to the connecting portion and is used to rotate to pull out the connecting portion.

[0014] In some embodiments of the present application, the rotating portion includes a first rotating sub-portion and a second rotating sub-portion, and the rotating portion is formed by connecting the first rotating sub-portion and the second rotating sub-portion. The first rotating sub-portion and the second rotating sub-portion are pulled forcefully, so that the rotating portion can be separated along the second connecting seam between the first rotating sub-portion and the second rotating sub-portion. The second connecting seam and the first connecting seam are staggered in the circumferential direction. The rotating portion is rotated until the second connecting seam is aligned with the first connecting seam, and the connecting portion is pulled out. Based on the gap remaining after pulling out the connecting portion, the first half cylinder, the second half cylinder, the first rotating sub-portion and the second rotating sub-portion are separated.

[0015] In a second aspect, an embodiment of the present application provides an endoscope, comprising an operating handle and a cable, wherein the operating handle is provided with a cable interface, the cable interface is used to dock with the cable, and the cable is provided with an endoscope cable protective cover.

[0016] Beneficial effects of this application:

[0017] By setting shrinkage ribs in the cylindrical film, the folding amount of the shrinkage ribs between two adjacent connection points of the cylindrical film and the shrinkage ribs is smaller than the folding amount of the cylindrical film. When the cylindrical film is unfolded to the far end, on the one hand, between any two adjacent connection points, the shrinkage ribs will be fully unfolded before the cylindrical film because the folding amount of the shrinkage ribs is smaller. When the shrinkage ribs are fully unfolded, the cylindrical film still maintains a slightly folded state, ensuring that the cylindrical film will not be stretched by excessive force in the axial direction, thereby causing it to be damaged. On the other hand, by setting shrinkage ribs on the inner wall of the cylindrical film, the cylindrical film and the cable itself can be isolated, forming a certain gap between the two, reducing the contact area between the cylindrical film and the cable surface, and further reducing the interaction force between the two, thereby avoiding the cylindrical film from being damaged due to the interaction force between the cable surface during use.

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0036] In order to facilitate understanding of the embodiments of the present application, the relevant technologies are first introduced in conjunction with application scenarios.

[0037] It should be noted that, in each embodiment of the present application, "proximal end" and "distal end" refer to the position of the endoscope and its accessories relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0038] In order to facilitate understanding of the embodiments of the present application, the relevant technologies are first introduced in conjunction with application scenarios.

[0039] During the use of the endoscope, the operating handle 500 needs to be connected to the host through the cable 600. The cable 600 is reusable, but because the cable 600 is exposed to the air during use, it may be contaminated with pollutants (for example, blood, etc.), and needs to be cleaned and disinfected before it can be used again. In order to reduce the cost of cleaning and disinfecting the cable 600, a protective cover can be provided on the cable 600 to protect it.

[0040] In the related art, when using the protective cover, it is necessary to pull it open and put it on the cable 600. However, in this process, the protective cover is often damaged. The inventors found that the main reason for the damage of the protective cover is that the protective cover is unevenly piled on the surface of the cable 600, resulting in excessive force and damage to some parts of the protective cover when it is unfolded, resulting in the failure of the protective cover to provide protection.

[0041] In view of this, the embodiment of the present application provides an endoscope cable protective cover and an endoscope, Figure 1-Figure 11 , describe in detail the technical solutions disclosed in each embodiment of this application.

[0042] In the embodiments of the present application, Figure 7 , 8 As shown in FIGS. 9 and 10 , the endoscope cable protective cover comprises a cylindrical film 100 and a contraction rib 200 . The cylindrical film 100 is a plastic film of a cylindrical structure, which can be covered on the surface of the cable 600 to protect it.

[0043] Since the cylindrical film 100 needs to be completely covered on the cable 600, its axial length is greater than the length of the cable 600. Therefore, the axial length of the cylindrical film 100 is too long, which is not convenient during transportation, storage and use. Therefore, the cylindrical film 100 needs to be compressed and folded in the axial length, and then stretched and unfolded during actual use.

[0044] Specifically, the tubular film 100 can be compressed and folded in the axial direction in a variety of ways, such as rolling or zigzag folding, so as to compress the axial length of the tubular film 100 .

[0045] like Figure 7 , 8 As shown in FIGS. 9 and 10 , the shrink ribs 200 are used to limit the extent to which the tubular film 100 is pulled apart in the axial direction. In some embodiments, the shrink ribs 200 may include a variety of structures, such as plastic belts, thin ropes, silk threads, and the like.

[0046] In some embodiments, the shrink ribs 200 are compressed and folded along the axial length in a manner similar to that of the tubular film 100 , which will not be described in detail herein.

[0047] In some embodiments, the shrink ribs 200 and the tubular film 100 may be connected in various ways, such as gluing, welding, etc.

[0048] Specifically, the shrink ribs 200 and the tubular film 100 have connection points 210 at least at the head and tail ends of the tubular film 100. In the specific implementation process, in order to better realize the protection function of the shrink ribs 200, the connection points 210 can be arranged more densely so that each section of the tubular film 100 can be protected.

[0049] When using the endoscope cable protective cover, it is necessary to fix the proximal end of the cylindrical film 100 and keep it still, and pull the distal end of the cylindrical film 100 to move toward the distal end of the cable 600. At this time, the cylindrical film 100 is pulled open and covers the surface of the cable 600 to protect the cable 600. Since the contraction ribs 200 are connected to the cylindrical film 100 at least at both ends, the contraction ribs 200 will unfold toward the distal end as the cylindrical film 100 moves. Because the folding amount of the contraction ribs 200 between any two connection points 210 is less than the folding amount of the cylindrical film 100, therefore, between any two connection points 210, the contraction ribs 200 will be fully unfolded before the cylindrical film 100, and at this time, the cylindrical film 100 still remains in a slightly folded state, so the cylindrical film 100 will not be stretched straight due to the tension and then damaged by the force.

[0050] By arranging the contraction ribs 200 in the tubular film 100, the folding amount of the contraction ribs 200 between two adjacent connection points 210 of the tubular film 100 and the contraction ribs 200 is smaller than the folding amount of the tubular film 100. When the tubular film 100 is unfolded toward the distal end, on the one hand, between any two adjacent connection points 210, the contraction ribs 200 are fully unfolded before the tubular film 100. At this time, the tension during the distal unfolding first acts on the contraction ribs 200, and when the contraction ribs 200 are fully unfolded, the tubular film 100 still maintains a slight fold, ensuring that the tubular film 100 will not be subjected to excessive force in the axial direction and be tightened, thereby causing it to be damaged. On the other hand, by setting the shrink ribs 200 inside the cylindrical film 100, the cylindrical film 100 and the cable 600 itself can be isolated, and a certain gap is formed between the two, which reduces the contact area between the surface of the cylindrical film 100 and the cable 600, and further reduces the interaction force between the two, thereby avoiding the damage of the cylindrical film 100 during use. In addition, since the surface of the cable 600 is usually made of rubber or other materials, and the cylindrical film 100 is usually made of plastic, in addition to the friction between the two, static adsorption will also be generated during the contact process. When the cylindrical film 100 and the cable 600 contact at a certain point, due to the electrostatic adsorption effect, the contact point between the cylindrical film 100 and the cable 600 will expand rapidly, forming a surface contact, thereby expanding the contact surface, and the contact area between the cylindrical film 100 and the cable 600 will continue to increase. At this time, under the combined effect of the pulling force that causes the cylindrical film 100 to unfold and the electrostatic adsorption, the cylindrical film 100 is very easy to be damaged. In the embodiment of the present application, by providing the shrinkage ribs 200, the range of the electrostatic adsorption between the cylindrical film 100 and the surface of the cable 600 can be further reduced, limiting the expansion of the adsorption area of ​​the electrostatic adsorption on the plane, thereby reducing the risk of damage to the cylindrical film 100.

[0051] In some embodiments, Figure 2 , 3 As shown in FIG. 4 , the endoscope cable protective sleeve further includes a barrel 300. The barrel 300 includes a first barrel 310 and a second barrel 320. The first barrel 310 and the second barrel 320 can be arranged opposite to each other along the axial direction, or, as shown in FIG. Figure 3 As shown, the second cylinder 320 is sleeved on the first cylinder 310 to form an inside-outside arrangement.

[0052] There is a receiving cavity (not shown) between the first cylinder 310 and the second cylinder 320, and the receiving cavity is used to store the cylindrical film 100. Since the cylindrical film 100 itself is a plastic film with low strength, it is easy to be damaged by external force. In addition, if the plastic film is directly exposed to the air, it will also be contaminated with dust and pollutants.

[0053] Therefore, by placing it in the accommodating cavity between the first cylinder 310 and the second cylinder 320, the cylindrical film 100 can be protected. One end of the cylindrical film 100 is connected to the first cylinder 310, and the other end is connected to the second cylinder 320. When the cylindrical film 100 needs to be unfolded, it is only necessary to keep the first cylinder 310 still and move the second cylinder 320 toward the distal end, and one end of the cylindrical film 100 will move toward the distal end axially with the second cylinder 320, thereby driving the cylindrical film 100 and the contraction rib 200 to unfold and lay on the cable 600 to protect the cable 600.

[0054] The first cylinder 310 and the second cylinder 320 are respectively connected to the cylindrical film 100 in a manner including gluing, welding, etc., which is not limited here.

[0055] In addition, in order to constrain the first barrel 310 and the second barrel 320 to maintain a certain relative position and prevent them from shifting, a connection portion is provided between the first barrel 310 and the second barrel 320. The connection portion is a weak connection and can be disconnected by an external force. When the second barrel 320 needs to be pulled to move to the far end, the connection portion can be disconnected by pulling the second barrel 320 with force, so that the first barrel 310 and the second barrel 320 can move relative to each other.

[0056] Exemplarily, the connection part may be glue with weak bonding force, or a knot, paper strip, plastic tape, etc. that is easy to break.

[0057] By providing the first barrel 310 and the second barrel 320, a storage cavity for storing the cylindrical film 100 is formed, and the cylindrical film 100 is wrapped, so that the cylindrical film 100 is protected from being damaged by external forces during transportation and storage, providing a good protective effect. On the other hand, by providing a connecting portion to connect the first barrel 310 and the second barrel 320, the relative position of the first barrel 310 and the second barrel 320 can be limited, thereby preventing the endoscope cable protective cover from being scattered or relatively dislocated when not in use, causing damage to the cylindrical film 100, and further improving the convenience of transporting and storing the endoscope cable protective cover.

[0058] In some embodiments, Fig.10 As shown, the tubular film 100 is folded in a zigzag shape in sequence in the axial direction, and a plurality of connection points 210 are located at the bottom of the tubular film 100 .

[0059] Since there is a connection structure (such as glue, etc.) at the connection point 210 between the cylindrical film 100 and the contraction rib 200, and based on the connection structure, the cylindrical film 100 and the contraction rib 200 are both subjected to force, the strength of the connection point 210 on the cylindrical film 100 is much greater than the strength of the part of the cylindrical film 100 that is not connected to the contraction rib 200. Therefore, when the cylindrical film 100 is stretched under tension, the part of the connection point 210 is less likely to be damaged than other unconnected parts. By setting the connection point 210 at the bottom of the cylindrical film 100, it can be ensured that in the process of unfolding the endoscope cable protective cover to the far end, the contact point between the cylindrical film 100 and the cable 600 (i.e., the bottom of the cylindrical film 100) is isolated by the contraction rib 200. At this time, only the contraction rib 200 and the surface of the cable 600 act with force, and the cylindrical film 100 is only subjected to force at the connection point 210, which ensures the safe unfolding of the cylindrical film 100 and will not be damaged during the unfolding process.

[0060] In some embodiments, Figure 3 As shown, the second cylinder 320 includes a first half cylinder 321 and a second half cylinder 322. The first half cylinder 321 and the second half cylinder 322 are weakly connected by various fixing methods such as gluing and clamping.

[0061] In some embodiments, the first half cylinder 321 and the second half cylinder 322 may be two completely identical halves, or one of the first half cylinder 321 and the second half cylinder 322 may be larger and the other smaller, which is not limited here.

[0062] When the endoscope cable protective cover is used up, if the protective cover is removed by taking it off, it is inevitable that the pollutants on the outside of the protective cover will fall onto the cable 600, causing pollution to the cable 600. Therefore, in order to achieve a better protection effect, when removing the endoscope cable protective cover, since the first half cylinder 321 and the second half cylinder 322 are weakly connected, the first half cylinder 321 and the second half cylinder 322 can be directly torn apart along the first connecting seam 323 between the first half cylinder 321 and the second half cylinder 322.

[0063] At this time, since the protective film is connected to the second cylinder 320 along the circumferential direction, when the second cylinder 320 is separated, the cylindrical film 100 connected to the first half cylinder 321 and the second half cylinder 322 will also separate with it, forming a crack, and correspondingly, the remaining cylindrical film 100 will also be torn apart with the crack. During the tearing process, the outer peripheral wall of the cylindrical film 100 that may be contaminated with pollutants is always outward and does not contact the cable 600, thereby greatly reducing the possibility of pollutants falling on the cable 600, and further forming a good protective effect on the cable 600 during the entire process of setting, using, and removing the endoscope cable protective cover.

[0064] By constructing the first half cylinder 321 and the second half cylinder 322 so as to make a weak connection therebetween, when the endoscope cable protective cover is used up, the connection between the first half cylinder 321 and the second half cylinder 322 can be directly disconnected by force, thereby tearing the cylindrical film 100 along both sides. During the tearing process, the contaminated surface of the cylindrical film 100 is always facing outward, thereby reducing the risk of contaminants dripping onto the surface of the cable 600 and further ensuring the protective effect of the endoscope cable protective cover on the cable 600.

[0065] In some embodiments, the endoscope cable protective cover further includes a separation portion (not shown in the figure), which is a guide line when tearing the tubular film 100 .

[0066] In some embodiments, the separation portion can be constructed in a variety of ways. For example, the separation portion can be a plastic film thinner than the thickness of the tubular film 100. For another example, the separation portion can be openings distributed along the axial direction.

[0067] The separation portion is disposed on the cylindrical film 100 along the axial direction. When the first semi-cylindrical body 321 and the second semi-cylindrical body 322 are separated, the cylindrical film 100 is torn along the separation portion.

[0068] Specifically, the separation portion can be arranged corresponding to the first connecting seam 323. When the first half cylinder 321 and the second half cylinder 322 are separated along the first connecting seam 323, an opening of the cylindrical film 100 is torn along the separation portion. Since the strength of the separation portion on the cylindrical film 100 is weakest in the circumferential direction, the force will continue to be transmitted axially along the separation portion, and the cylindrical film 100 will be torn along the separation portion, thereby avoiding problems such as the cylindrical film 100 breaking in the middle of the tearing process.

[0069] In some embodiments, in order to ensure that the strength of the cylindrical film 100 itself does not change and to prevent pores in the cylindrical film 100 that would cause pollutants to enter the cylindrical film 100 through the pores, the separation portion may be configured as a separation rib.

[0070] The separation ribs are connected to the tubular film 100 in the axial direction. In some embodiments, the separation ribs can be various structures, such as thin ropes, silk threads, etc.

[0071] The separation ribs have the same folding amount as the tubular film 100 , that is, the separation ribs can continuously provide separation guidance to the tubular film 100 in the axial direction to prevent the tubular film 100 from breaking or branching in the middle.

[0072] Specifically, there can be multiple separation ribs, which can be arranged on the inner circumferential wall or the outer circumferential wall of the cylindrical film 100, corresponding to the position of the first connection seam 323. At this time, when the first half cylinder 321 and the second half cylinder 322 are separated along the first connection seam 323, the cylindrical film 100 is separated along the separation ribs.

[0073] The separation ribs can also be arranged in a variety of ways. Exemplarily, every two separation ribs constitute a group of separation ribs, and the two separation ribs in a group of separation ribs are symmetrically arranged on the inner circumferential wall and / or outer circumferential wall of the cylindrical film 100 at both sides of the first connection seam 323. At this time, since the strength of the cylindrical film 100 at the position connected to the separation ribs is greater than the position not connected to the separation ribs, the position between the two separation ribs naturally becomes a position with weaker strength. When the first half cylinder 321 and the second half cylinder 322 are separated along the first connection seam 323, the distal end of the cylindrical film 100 will first tear an opening from the first connection seam 323 (i.e., the position between the two separation ribs). When tearing downwards, due to the limitation of the two separation ribs, the cylindrical film 100 will be torn downwards along the weak position in the middle of the separation ribs. In the entire process of tearing the cylindrical film 100, the cracking line of the cylindrical film 100 is limited between the two symmetrically arranged separation ribs.

[0074] By setting separation ribs, the tearing trajectory of the cylindrical film 100 can be limited without changing the state of the cylindrical film 100 itself. Avoid weak parts or openings on the cylindrical film 100, which will affect the strength and sealing condition of the cylindrical film 100 itself and reduce its protective effect on the cable 600. At the same time, separation ribs are symmetrically set on the inner circumferential wall and / or outer circumferential wall of the cylindrical film 100 on both sides of the first connecting seam 323, so that the cylindrical film 100 is torn along the two separation ribs, which can further limit the trajectory of the cylindrical film 100 when being torn, so that the cylindrical film 100 is torn in half, and the convenience of tearing the cylindrical film 100 is improved. Moreover, when the separation ribs are set on the inner circumferential wall of the cylindrical film 100, the separation ribs can also play a role in isolating the cylindrical film 100 from the surface of the cable 600.

[0075] In some embodiments, Figure 3 , 4 As shown in FIG. 5 , the endoscope cable protective cover further includes at least one coupling portion 410. The coupling portion 410 is disposed at the first connecting seam 323 and is used to isolate the first half cylinder 321 and the second half cylinder 322 so that a gap is left therebetween to facilitate separation of the first half cylinder 321 and the second half cylinder 322.

[0076] Illustratively, the coupling portion 410 may be disposed only at a portion of the first connection seam 323 .

[0077] Exemplarily, the coupling portion 410 may also cover the entire first connection seam 323 to form a connection structure connecting the first semi-cylinder 321 and the second semi-cylinder 322. At this time, the coupling portion 410 is pulled out, and the first semi-cylinder 321 and the second semi-cylinder 322 are naturally separated.

[0078] In some embodiments, the connecting portion 410 is a sheet structure with a certain thickness. Specifically, the connecting portion 410 can be a plastic sheet with a certain thickness. The thickness of the connecting portion 410 can be set manually as needed and is not limited here.

[0079] In some embodiments, the connecting portion 410 may be disposed only between one first connecting seam 323 , or may be disposed at two first connecting seams 323 at the same time.

[0080] When the connecting portion 410 is pulled out, a gap will be left at the first connecting seam 323 . Based on the gap, external force can be applied to the first half cylinder 321 and the second half cylinder 322 respectively, so that the first half cylinder 321 and the second half cylinder 322 can be separated along the first connecting seam 323 .

[0081] By providing the connecting portion 410 , the first half cylinder 321 and the second half cylinder 322 can be separated more conveniently, thereby avoiding the problem of difficulty in applying force during separation, and greatly improving the convenience of separating the first half cylinder 321 and the second half cylinder 322 .

[0082] In some embodiments, Figure 2 , 3 As shown in FIG. 4 , the endoscope cable protective cover further includes a rotating portion 400 for rotating to extract the connecting portion 410 .

[0083] The rotating part 400 is sleeved on the outer peripheral wall of the second cylinder 320, and the rotating part 400 can rotate relative to the second cylinder 320. Exemplarily, the inner peripheral wall of the rotating part 400 can be clamped with the outer peripheral wall of the second cylinder 320, or the second cylinder 320 is provided with a groove along the circumferential direction, the groove clamps the rotating part 400 in the axial direction, and the rotating part 400 can rotate in the groove along the circumferential direction.

[0084] The rotating part 400 and the connecting part 410 are fixedly connected by various methods, such as gluing, welding, etc. When the rotating part 400 is rotated, the connecting part 410 fixedly connected to the rotating part 400 will rotate along with the rotating part 400, be pulled out from the first connecting seam 323, and stay in the gap between the rotating part 400 and the outer peripheral wall of the second cylinder 320.

[0085] By setting the rotating part 400 sleeved on the outside of the second cylinder 320, the second cylinder 320 can be limited in the axial direction to prevent the second cylinder 320 from being hit or collided before use, so that the first half cylinder 321 of the second cylinder 320 is disconnected from the second half cylinder 322, affecting the normal use of the endoscope cable protective cover. Secondly, by rotating the rotating part 400 to extract the connecting part 410, the force of extraction and extraction can be converted into torsion, which simplifies the extraction action of the connecting part 410 and improves the user experience of the operator. In addition, a groove is provided on the second cylinder 320 to clamp the rotating part 400, which can reduce the protrusion of the rotating part 400 in the circumferential direction. On the basis of convenient clamping, the simplicity of its packaging is improved, and the assembly process of the two is simplified at the same time, reducing the production cost of the endoscope cable protective cover.

[0086] In some embodiments, the rotating part 400 includes a first rotating sub-part 420 and a second rotating sub-part 430. Exemplarily, the first rotating sub-part 420 and the second rotating sub-part 430 can be two halves symmetrical along the center of the rotating part 400, or the first rotating sub-part 420 and the second rotating sub-part 430 are arranged in a large and a small configuration, similar to the first semi-cylinder 321 and the second semi-cylinder 322, which is not limited here.

[0087] The first rotating sub-part 420 and the second rotating sub-part 430 are weakly connected. By pulling the first rotating sub-part 420 and the second rotating sub-part 430, the rotating part 400 can be separated along the second connecting seam 440 between the first rotating sub-part 420 and the second rotating sub-part 430. The connection method between the first rotating sub-part 420 and the second rotating sub-part 430 is similar to the connection method between the first semi-cylinder 321 and the second semi-cylinder 322, and will not be repeated here.

[0088] Since the rotating portion 400 has a limiting effect on the second cylinder 320 in the radial direction, the second connecting seam 440 and the first connecting seam 323 are staggered in the circumferential direction, that is, the second connecting seam 440 and the first connecting seam 323 are not aligned to avoid the first connecting seam 323 and the second connecting seam 440 being disconnected due to being stressed at the same time.

[0089] When it is necessary to remove the endoscope cable protective cover, the rotating part 400 is rotated until the second connecting seam 440 is aligned with the first connecting seam 323, and the connecting part 410 is pulled out. Based on the remaining gap after pulling out the connecting part 410, the first half cylinder 321 and the second half cylinder 322 are separated, and the first rotating sub-part 420 and the second rotating sub-part 430 arranged on the outside thereof are also separated by force at the same time.

[0090] By setting the first rotating sub-section 420 and the second rotating sub-section 430, the rotating section 400 can be separated by separating the first half cylinder 321 and the second half cylinder 322, which simplifies the steps of separating the rotating section 400 from the second cylinder 320. At the same time, the second connecting seam 440 and the first connecting seam 323 are staggered to ensure the limiting effect of the rotating section 400 on the second cylinder 320 in the axial direction. When the rotating section 400 is rotated, the connecting section 410 is pulled out on the one hand, and the first connecting seam 323 is aligned with the second connecting seam 440, and external force is applied to them, so that the second cylinder 320 can be separated from the rotating section 400 together, simplifying the disassembly process of the endoscope cable protective cover, and preventing it from being accidentally disconnected due to external force when it is not used, thereby improving the convenience and safety of using the endoscope cable protective cover.

The operating handle 500 is provided with a cable 600 interface, the cable 600 interface is used for docking with the cable 600, and the cable 600 is provided with an endoscope cable protective cover.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
