Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly to a probe sheath wearing device and an ultrasonic imaging system. Background Art

[0002] Endocavity ultrasonic probes have advantages such as a large ultrasonic field of view, high resolution, clear images, and accurate positioning, and are currently widely used in the examination of various diseases. When an endocavity ultrasonic probe is in use, a sheath needs to be worn on the probe. If a doctor manually wears the sheath on the probe, hand bacteria will be introduced, and the doctor will also need to perform frequent disinfection and cleaning operations, which is very inconvenient.

[0003] Therefore, a probe sheath wearing device is usually introduced to assist in wearing. However, the existing probe sheath wearing devices are usually provided with a cover to limit the sheath to prevent the sheath from falling off when wearing the sheath on the probe. When such a probe sheath wearing device is in use, after wearing the sheath on the probe, it is necessary to release the limit of the cover on the sheath to take out the probe with the worn sheath, and the operation is very troublesome.

[0036] In the following description, a large number of details are provided to enable a thorough understanding of the present invention. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some well-known technical features in the art are not described in detail.

[0037] According to one aspect of the present invention, a probe protective cover wearing device is provided. The probe protective cover wearing device can be applied to any suitable system, including but not limited to an ultrasonic imaging system. Therefore, according to another aspect of the present invention, an ultrasonic imaging system is provided. The ultrasonic imaging system can include a probe, an ultrasonic device, and any one of the probe protective cover wearing devices to be introduced below. The probe protective cover wearing device can be connected to an ultrasonic host, a control panel, an ultrasonic examination bed, a desktop, etc. The probe can be an intracavitary ultrasonic probe, a volume probe, or any other suitable form. The probe protective cover wearing device can assist in wearing a protective cover on the probe, and during the process of wearing the protective cover on the probe, it can reduce the contact between the operator's hand and the protective cover to meet the sterile environment required when the probe is used, and reduce the required disinfection and cleaning actions.

[0038] See Figure 1 and Figure 2, the probe protective cover wearing device 11 may include a seat body 100. A through hole 110 for inserting the probe 12 may be formed on the seat body 100. The through hole 110 may be in the form of a through hole on the seat body 100. At least a portion of the probe 12 may pass through the through hole 110. The through hole 110 may have a size and shape that is compatible with the probe 12. For example, for a probe 12 in the form of a volume probe, the through hole 110 may have a larger size, while for a probe 12 in the form of an intracavitary ultrasound probe, the size of the through hole 110 may be relatively small. When the probe protective cover wearing device 11 is applied to an ultrasound imaging system, the seat body 100 may be connected to an ultrasound device, so that the probe protective cover wearing device 11 may be connected to the ultrasound device. The seat body 100 may be connected to a connecting frame 300, and the connecting frame 300 may be rotatably connected to the ultrasound device. A connection groove 310 may be provided at one end of the connection frame 300 away from the base body 100, and a connection bolt 320 may be inserted into the connection groove 310, and a connection bearing 330 may be provided between the connection bolt 320 and the inner side wall of the connection groove 310. The connection bolt 320 may be threadedly connected to the ultrasonic device, and the connection frame 300 may rotate relative to the connection bolt 320, so that the connection frame 300 may be rotatably connected to the ultrasonic device. A gasket 340 may also be provided between the connection frame 300 and the ultrasonic device, and the gasket 340 may be abutted against the outer peripheral edge of the connection groove 310, and the gasket 340 may reduce the rotational friction, so that the connection frame 300 may rotate more smoothly relative to the ultrasonic device. The ultrasonic device may include a control panel, and the connecting bolt 320 may be threadedly connected to the bottom of the control panel of the ultrasonic device, so that the connecting frame 300 may be hung under the control panel of the ultrasonic device. When the probe protective cover wearing device 11 needs to be used, the connecting frame 300 may be unscrewed. After use, the connecting frame 300 may be rotated to hide the probe protective cover wearing device 11 under the control panel of the ultrasonic device. In particular, the connecting bolt 320 may be in the form of a stepped bolt, and such a connecting bolt 320 may have a threaded section and a non-threaded section, wherein the threaded section may be used to connect to the ultrasonic device, and the non-threaded section may be used to connect to the connecting frame 300, so that the connecting frame 300 may be threadedly connected to the ultrasonic device through the connecting bolt 320 in the form of a stepped bolt, and may be smoothly rotated around the connecting bolt 320, so that the probe protective cover wearing device 11 may be more smoothly unscrewed and retracted relative to the ultrasonic device. Connecting the probe protective cover wearing device 11 to the ultrasonic device in this manner may reduce the overall space occupied.

[0039] On the base body 100, a protruding portion 120 for insertion into the protective sleeve 13 can be provided. The protruding portion 120 can protrude along the periphery of the through hole 110 toward the first direction (the X direction shown in the figure), and the protruding portion 120 can be in the form of an annular protrusion. The protruding portion 120 can be integrally formed with the base body 100 or connected to the base body 100 in the form of an independent component. The protective sleeve 13 is usually a condom or has a structure similar to that of a condom. The protective sleeve 13 can have a rim 13a. By folding the opening of the fully unfolded protective sleeve 13, the protective sleeve 13 in the form that has not been unfolded can be obtained. The protective sleeve 13 in the form that has not been unfolded can have a rim 13a and a middle portion 13b. Usually, the protective sleeve 13 in the form that has not been unfolded is used for wearing. When wearing the protective sleeve 13, folding the rim 13a can make the protective sleeve 13 sleeved on the probe 12. In this process, the rim 13a gradually becomes smaller and the middle portion 13b gradually becomes larger. The protective sleeve 13 can have a direction. For example, as shown in Figure 1 and Figure 2 the protective sleeve 13 shown is in the second direction (the Y direction shown in the figure). Folding the rim 13a in the first direction X opposite to the second direction Y can unfold the protective sleeve 13, so that the probe 12 wears the protective sleeve 13. The rim 13a can be sleeved on the protruding portion 120. There can be a first gap between the probe 12 inserted into the through hole 110 and the protruding portion 120 to limit the rim 13a of the protective sleeve 13. The first gap can be the gap between the probe 12 and the inner side wall of the protruding portion 120. When the probe 12 is inserted into the through hole 110, a gap will naturally be formed between the probe 12 and the inner side wall of the protruding portion 120. The probe 12 inserted into the through hole 110 can abut against the middle portion 13b of the protective sleeve 13. The probe 12 inserted into the through hole 110 along the second direction Y makes the middle portion 13b of the protective sleeve 13 also move toward the second direction Y. As a result, the rim 13a is abutted by the protruding portion 120, and the protruding portion 120 exerts an abutting force on the rim 13a toward the first direction X, which is equivalent to making the rim 13a fold toward the first direction X. In this way, the rim 13a will gradually become smaller and the middle portion 13b will gradually become larger until the probe 12 is completely worn with the protective sleeve 13. Among them, since there can be a first gap between the probe 12 and the protruding portion 120 to limit the rim 13a, when the probe 12 abuts against the middle portion 13b and moves together toward the second direction Y, the rim 13a cannot pass through the first gap and thus cannot move toward the second direction Y and is always abutted by the protruding portion 120 and folds toward the first direction X. Based on this, the first gap actually forms a limit for the rim 13a. And during the process of wearing the protective sleeve 13 on the probe 12, the rim 13a will gradually become smaller. The meaning that the first gap forms a limit for the rim 13a here is that until the probe 12 is completely worn with the protective sleeve 13, during this process, even when the rim 13a has the smallest size, it cannot pass through the first gap.

[0040] The probe protection sleeve wearing device 11 provided by the present utility model utilizes the first gap between the probe 12 inserted into the through hole 110 and the protruding portion 120 to limit the circular edge of the protection sleeve 13, which can prevent the protection sleeve 13 from falling off when the protection sleeve 13 is worn on the probe 12. In this way, the protection sleeve 13 is limited, and there is no need to design other special structures on the protection sleeve 13 wearing device to limit the protection sleeve 13, so the overall structure can be simpler. Since the circular edge is simply sleeved on the protruding portion 120, after the protection sleeve 13 is worn on the probe 12, the probe 12 with the protection sleeve 13 worn can be directly taken out from the through hole 110. Such a protection sleeve 13 wearing device is more convenient to operate and can provide a better user experience. Moreover, such a protection sleeve 13 wearing device is conducive to reuse, and the cost can be lower.

[0041] In an embodiment of the present utility model, a rounded surface may be formed at one end of the protruding portion 120 away from the seat body 100 in the first direction X. The contact surface between the protruding portion 120 and the protection sleeve 13 may be in the form of a rounded surface, which can reduce the friction force when folding the circular edge 13a. In this way, during the process of wearing the protection sleeve 13 on the probe 12, that is, when folding the circular edge 13a, it can be smoother and it can be easier to complete the wearing of the protection sleeve 13 on the probe 12.

[0042] Exemplarily, the rounded surface may include a semi-circular cross-section. This can further reduce the friction force when folding the circular edge 13a, so that during the process of wearing the protection sleeve 13 on the probe 12, when folding the circular edge 13a, it can be smoother, and thus it can be easier to complete the wearing of the protection sleeve 13 on the probe 12.

[0043] In an embodiment of the present utility model, the protruding portion 120 may include a plurality of roller structures (not shown in the figure) connected to each other, and the rotation direction of the roller structures may be the same as the folding direction of the circular edge 13a. The plurality of roller structures connected to each other may be formed by arranging and connecting a plurality of rollers in sequence along their respective axial directions. Such a protruding portion 120 is actually connected to the seat body 100 as an independent component. The friction between such a protruding portion 120 and the protection sleeve 13 is changed from sliding friction to rolling friction, further reducing the friction force when folding the circular edge 13a, so that during the process of wearing the protection sleeve 13 on the probe 12, when folding the circular edge 13a, it can be smoother, and thus it can be easier to complete the wearing of the protection sleeve 13 on the probe 12.

[0044] In an embodiment of the present utility model, refer to Figure 3 、 Figure 4 and Figure 5, the probe protective cover wearing device 11 may include a locking limit mechanism 200 that can be switched between a locked state and an unlocked state. The locking limit mechanism 200 may include a first limiting member 210. The first limiting member 210 may be rotatably connected to the base body 100. The first limiting member 210 may be rotatably connected to the base body 100 by means of threaded connection or any other form. The first limiting member 210 may include a first arc segment 213. Wherein, when the locking limit mechanism 200 is in the locked state, the first arc segment 213 may limit the protective cover 13. The first arc segment 213 limiting the protective cover 13 may be achieved by a gap formed between the peripheral edge of the first arc segment 213 and the protruding portion 120 to limit the loop edge 13a. When the locking limit mechanism 200 is in the unlocked state, the first arc segment 213 may release the limit on the protective cover 13. On the basis that a first gap between the probe 12 and the protruding portion 120 limits the protective cover 13, the setting of the locking limit mechanism 200 can limit the protective cover 13 through the first arc segment 213, so that when the locking limit mechanism 200 is in the locked state, the overall device has better limitation on the protective cover 13, and the protective cover 13 is less likely to fall off.

[0045] In an embodiment of the present invention, refer to Figure 3 , Figure 4 and Figure 5, the probe protection sleeve wearing device 11 may include a locking limit mechanism 200 that can be switched between a locked state and an unlocked state. The locking limit mechanism 200 may include a first limit member 210 and a second limit member 220. The first limit member 210 and the second limit member 220 may both be rotatably connected to the seat body 100. The first limit member 210 and the second limit member 220 may be rotatably connected to the seat body 100 by means of threaded connection or any other form, wherein the form in which the first limit member 210 is rotatably connected to the seat body 100 may be the same as or different from the form in which the second limit member 220 is rotatably connected to the seat body 100. The first limit member 210 may include a first arc segment 213, and the second limit member 220 may include a second arc segment 223. When the locking limit mechanism 200 is in the locked state, it may be that either the first arc segment 213 or the second arc segment 223 individually forms a limit on the protection sleeve 13; correspondingly, when the locking limit mechanism 200 is in the unlocked state, it may be that either the first arc segment 213 or the second arc segment 223 releases the limit on the protection sleeve 13, which is similar to the first arc segment 213 forming a limit on the protection sleeve 13 or the first arc segment 213 releasing the limit on the protection sleeve 13 in the above text, and will not be elaborated here. When the locking limit mechanism 200 is in the locked state, the first arc segment 213 and the second arc segment 223 may together form a limit on the protection sleeve 13; correspondingly, when the locking limit mechanism 200 is in the unlocked state, the first arc segment 213 and the second arc segment 223 may release the limit on the protection sleeve 13. Since the first limit member 210 and the second limit member 220 are both rotatably connected to the seat body 100, by respectively rotating the first limit member 210 and the second limit member 220, a relative position may exist between the first limit member 210 and the second limit member 220, and at this time, the first arc segment 213 may enclose with the second arc segment 223. When the first arc segment 213 encloses with the second arc segment 223, a through hole substantially the same as the through hole 110 may be formed. Among them, when the locking limit mechanism 200 is in the locked state, the first arc segment 213 and the second arc segment 223 may enclose to form a limit on the protection sleeve 13. The first arc segment 213 and the second arc segment 223 enclosing to form a limit on the protection sleeve 13 may be achieved by having a gap for limiting the loop edge 13a formed between the peripheries of the first arc segment 213 and the second arc segment 223 and the protruding portion 120. When the locking limit mechanism 200 is in the unlocked state, the first arc segment 213 and the second arc segment 223 may be separated to release the limit on the protection sleeve 13. Of course, even when the first arc segment 213 and the second arc segment 223 together form a limit on the protection sleeve 13, when releasing the limit on the protection sleeve 13, it may also be achieved by rotating either the first arc segment 213 or the second arc segment 223.On the basis that a first gap between the probe 12 and the protruding portion 120 limits the protective sleeve 13, the locking and limiting mechanism 200 can limit the protective sleeve 13 when the first arc segment 213 and the second arc segment 223 are enclosed. When the locking and limiting mechanism 200 is in the locked state, the overall device has better limitation on the protective sleeve 13, and the protective sleeve 13 is less likely to fall off. It should be noted that through reasonable dimension design, it is possible to take out the probe 12 with the protective sleeve 13 worn without the locking and limiting mechanism 200 being in the unlocked state. For example, after the first arc segment 213 and the second arc segment 223 are enclosed, a gap for limiting the protective sleeve 13 is formed between the whole and the protruding portion 120. This gap can be slightly larger than the first gap. That is to say, the locking and limiting mechanism 200 can participate in limiting the edge 13a when the edge 13a has a larger size. As the protective sleeve 13 is folded, the edge 13a gradually becomes smaller, and the locking and limiting mechanism 200 may not limit the edge 13a with a smaller size. Since there is a first gap between the probe 12 and the protruding portion 120, the protective sleeve 13 still will not fall off. On this basis, only by designing the through hole formed by enclosing the first arc segment 213 and the second arc segment 223 to be larger, the probe 12 can be directly taken out after the probe 12 wears the protective sleeve 13. In this way, through reasonable dimension design, it is actually equivalent to realizing the automatic unlocking of the locking and limiting mechanism 200 through the size change of the edge 13a. Of course, after the probe 12 wears the protective sleeve 13, the locking and limiting mechanism 200 can also be switched to the unlocked state. For example, at least one of the first limiting member 210 and the second limiting member 220 can be rotated so that the first arc segment 213 and the second arc segment 223 are separated, and the limitation of the protective sleeve 13 by the locking and limiting mechanism 200 can be released. The setting of the locking and limiting mechanism 200 can make the protective sleeve 13 less likely to fall off, and the overall device has stronger stability during use; moreover, the locking and limiting mechanism 200 does not make it more complicated to take out the probe 12 with the protective sleeve 13 worn. Whether through reasonable dimension design or rotating at least one of the first limiting member 210 and the second limiting member 220 to unlock the locking and limiting mechanism 200 to take out the protective sleeve 13 is very convenient.

[0046] Exemplarily, referring to Figure 5, a first auxiliary convex edge 214 may be provided on the periphery of the first arc segment 213 and protrude towards the base 100. The first auxiliary convex edge 214 may have a similar extension trend to the first arc segment 213. The first auxiliary convex edge 214 may be in the form of an arc-shaped protrusion. The first auxiliary convex edge 214 may be integrally formed with the first limiting member 210, or may be connected together in various forms such as welding after being separately processed. A second auxiliary convex edge 224 may be provided on the periphery of the second arc segment 223 and protrude towards the base 100. The second auxiliary convex edge 224 may have a similar extension trend to the second arc segment 223. The second auxiliary convex edge 224 may be in the form of an arc-shaped protrusion. The second auxiliary convex edge 224 may be integrally formed with the second limiting member 220, or may be connected together in various forms such as welding after being separately processed. When the locking and limiting mechanism 200 is in the locked state, there may be a second gap with a limiting ring edge between the first auxiliary convex edge 214 and / or the second auxiliary convex edge 224 and the protruding portion 120. The first auxiliary convex edge 214 or the second auxiliary convex edge 224 may separately have a second gap with the protruding portion 120, or the first auxiliary convex edge 214 and the second auxiliary convex edge 224 may enclose and have a second gap with a limiting ring edge between them and the protruding portion 120. The forms of the first auxiliary convex edge 214 and the second auxiliary convex edge 224 may be the same or different. The settings of the first auxiliary convex edge 214 and the second auxiliary convex edge 224, when the locking and limiting mechanism 200 is in the locked state, may cause a gap to exist between the first limiting member 210 and the second limiting member 220 as a whole and the base 100. An operator can observe the state of the protective cover 13 in the gap to avoid the protective cover 13 being broken during the process of wearing the protective cover 13 on the probe 12 and not being discovered.

[0047] See Figure 3 , Figure 4 and Figure 5, a support column 130 can be provided on the seat body 100 to protrude along the first direction X. Among them, exemplarily, a first auxiliary support column 215 can be provided on the side of the first limiting member 210 facing the seat body 100. When the first limiting member 210 is in the locked state, the first auxiliary support column 215 can abut against the support column 130. When the first limiting member 210 is in the locked state, the first limiting member 210 can limit the protective sleeve 13. At this time, it can be considered that the locking and limiting mechanism 200 is also in the locked state. When the first auxiliary support column 215 abuts against the support column 130, the first auxiliary support column 215 and the support column 130 as a whole can make the relative position of the first limiting member 210 and the seat body 100 more stable. The arrangement of the first auxiliary support column 215 and the support column 130 can also make the structure of the overall device more stable. Since there may be a gap between the first limiting member 210 and the seat body 100 for the operator to observe the state of the protective sleeve 13, the arrangement of the first auxiliary support column 215 and the support column 130 can also make this gap more stable. When the first limiting member 210 is located above the seat body 100, the seat body 100 can provide better support for the first limiting member 210 by abutting against the first auxiliary support column 215 through the support column 130.

[0048] Exemplarily, a second auxiliary support column 225 can be provided on the side of the second limiting member 220 facing the seat body 100. When the second limiting member 220 is in the locked state, the second auxiliary support column 225 can abut against the support column 130. When the second limiting member 220 is in the locked state, the second limiting member 220 can limit the protective sleeve 13. At this time, it can be considered that the locking and limiting mechanism 200 is also in the locked state. When the second auxiliary support column 225 abuts against the support column 130, the second auxiliary support column 225 and the support column 130 as a whole can make the relative position of the second limiting member 220 and the seat body 100 more stable. The arrangement of the second auxiliary support column 225 and the support column 130 can also make the structure of the overall device more stable. Since there may be a gap between the second limiting member 220 and the seat body 100 for the operator to observe the state of the protective sleeve 13, the arrangement of the second auxiliary support column 225 and the support column 130 can also make this gap more stable. When the second limiting member 220 is located above the seat body 100, the seat body 100 can provide better support for the second limiting member 220 by abutting against the second auxiliary support column 225 through the support column 130.

[0049] Exemplarily, refer to Figure 4 , the first limiting member 210 can have opposite first and second ends 211 and 212, and the first arc segment 213 can be located between the first end 211 and the second end 212. Referring to Figure 5, a first rotating groove 2111 may be provided on the first end 211. A first rotating bolt 2112 may be inserted into the first rotating groove 2111. A first rotating bearing 2113 may be provided between the inner side wall of the first rotating groove 2111 and the first rotating bolt 2112. The first end 211 may be rotatably connected to the seat body 100 through the first rotating bolt 2112. A first rotating handle 2122 may be provided on the second end 212. The first rotating bolt 2112 may have a non-threaded section and a threaded section. The threaded section may be threadedly connected to the seat body 100, and the non-threaded section may be inserted into the first rotating groove 2111 through the first rotating bearing 2113. Thus, the first rotating bolt 2112 may be threadedly connected to the seat body 100, and the first limiting member 210 may rotate relative to the first rotating bolt 2112, so that the first limiting member 210 can be rotatably connected to the seat body 100. Among them, the length of the non-threaded section on the first rotating bolt 2112 may not be less than the length of the first rotating groove 2111. In this way, the first limiting member 210 is rotatably connected to the seat body 100, and the overall structure is simpler. The first rotating handle 2122 may be designed in any form as needed. The setting of the first rotating handle 2122 can make it simpler and more convenient to rotate the first limiting member 210.

[0050] Exemplarily, referring to Figure 4 , the second limiting member 220 may have opposite third end 221 and fourth end 222, and the second arc segment 223 may be located between the third end 221 and the fourth end 222. Referring to Figure 5 , a second rotating groove 2211 may be provided on the third end 221. A second rotating bolt 2212 may be inserted into the second rotating groove 2211. A second rotating bearing 2213 may be provided between the inner side wall of the second rotating groove 2211 and the second rotating bolt 2212. The third end 221 may be rotatably connected to the seat body 100 through the second rotating bolt 2212. A second rotating handle 2222 may be provided on the fourth end 222. The second rotating bolt 2212 may have a non-threaded section and a threaded section. The threaded section may be threadedly connected to the seat body 100, and the non-threaded section may be inserted into the second rotating groove 2211 through the second rotating bearing 2213. Thus, the second rotating bolt 2212 may be threadedly connected to the seat body 100, and the second limiting member 220 may rotate relative to the second rotating bolt 2212, so that the second limiting member 220 can be rotatably connected to the seat body 100. Among them, the length of the non-threaded section on the second rotating bolt 2212 may not be less than the length of the second rotating groove 2211. In this way, the second limiting member 220 is rotatably connected to the seat body 100, and the overall structure is simpler. The second rotating handle 2222 may be designed in any form as needed. The setting of the second rotating handle 2222 can make it simpler and more convenient to rotate the second limiting member 220.

[0051] Exemplarily, referring to Figure 5 , a first magnetic attraction member 141 may be provided on the base body 100, and a first magnetic attraction mating member 2121 may be provided on the first limiting member 210. When the locking and limiting mechanism 200 is in the locked state, the first magnetic attraction member 141 and the first magnetic attraction mating member 2121 may form a magnetic attraction mating. The position where the first magnetic attraction member 141 is provided on the base body 100 may correspond to the position where the first limiting member 210 is located when the locking and limiting mechanism 200 is in the locked state. The arrangement of the first magnetic attraction member 141 and the first magnetic attraction mating member 2121 can lock the position of the first limiting member 210 when the locking and limiting mechanism 200 is in the locked state through magnetic attraction mating. In this way, the locking and unlocking of the position of the first limiting member 210 are both simpler and more convenient. Particularly, in an embodiment where a support column 130 is provided on the base body 100 and a first auxiliary support column 215 is provided on the first limiting member 210, the first magnetic attraction member 141 may be provided in the support column 130, and the first magnetic attraction mating member 2121 may be provided in the first auxiliary support column 215. For example, magnet accommodation grooves may be provided in the support column 130 and the first auxiliary support column 215, and the first magnetic attraction member 141 and the first magnetic attraction mating member 2121 may be respectively provided in the magnet accommodation grooves. This can further save space.

[0052] Exemplarily, a second magnetic attraction member 142 may be provided on the base body 100, and a second magnetic attraction mating member 2221 may be provided on the second limiting member 220. When the locking and limiting mechanism 200 is in the locked state, the second magnetic attraction member 142 and the second magnetic attraction mating member 2221 may form a magnetic attraction mating. The position where the second magnetic attraction member 142 is provided on the base body 100 may correspond to the position where the second limiting member 220 is located when the locking and limiting mechanism 200 is in the locked state. The arrangement of the second magnetic attraction member 142 and the second magnetic attraction mating member 2221 can lock the position of the second limiting member 220 when the locking and limiting mechanism 200 is in the locked state through magnetic attraction mating. In this way, the locking and unlocking of the position of the second limiting member 220 are both simpler and more convenient. Particularly, in an embodiment where a support column 130 is provided on the base body 100 and a second auxiliary support column 225 is provided on the second limiting member 220, the second magnetic attraction member 142 may be provided in the support column 130, and the second magnetic attraction mating member 2221 may be provided in the second auxiliary support column 225. For example, magnet accommodation grooves may be provided in the support column 130 and the second auxiliary support column 225, and the second magnetic attraction member 142 and the second magnetic attraction mating member 2221 may be respectively provided in the magnet accommodation grooves. This can further save space.

[0053] In an embodiment of the present utility model, referring to Figure 6 and Figure 7, the probe protective cover wearing device 11 may include a locking limit mechanism 200 that can be switched between a locked state and an unlocked state. The locking limit mechanism 200 may include a third limiting member 230. The third limiting member 230 may include a third arc segment 231 and a first connection end 232 opposite to the third arc segment 231. The first connection end 232 may be rotatably connected to the seat body 100 so that the third limiting member 230 can be rotated relative to the seat body 100 between a first folding position and a first opening position. Wherein, when the third limiting member 230 is in the first folding position, the locking limit mechanism 200 may be in the locked state, and the third arc segment 231 may limit the protective cover 13; when the third limiting member 230 is in the first opening position, the locking limit mechanism 200 may be in the unlocked state. The first connection end 232 may be rotatably connected to the seat body 100 through a hinge structure or any other suitable form. As Figure 6 and Figure 7In the illustrated embodiment, the third limiting member 230 is in the first folding position. It can be understood that the first opening position of the third limiting member 230 does not refer to a single position point, but can be a set of positions. For example, after the third limiting member 230 leaves the first folding position, there are many positions where the third limiting member 230 can keep the locking and limiting mechanism 200 in the unlocked state, and all these positions can be considered as the first opening position. On the basis that the first gap between the probe 12 and the protrusion 120 limits the protective sleeve 13, the setting of the locking and limiting mechanism 200 can limit the protective sleeve 13 through the third arc segment 231, so that when the locking and limiting mechanism 200 is in the locked state, the overall device has better limitation on the protective sleeve 13, and the protective sleeve 13 is less likely to fall off. It should be noted that through reasonable dimension design, it is possible to take out the probe 12 with the protective sleeve 13 worn without the locking and limiting mechanism 200 being in the unlocked state. For example, a gap for limiting the protective sleeve 13 is formed between the third arc segment 231 and the protrusion 120, and this gap can be slightly larger than the first gap. That is to say, the locking and limiting mechanism 200 can participate in limiting the edge 13a when the edge 13a has a larger size, and as the protective sleeve 13 is folded, the edge 13a gradually becomes smaller, and the locking and limiting mechanism 200 may not limit the smaller-sized edge 13a. Since there is a first gap between the probe 12 and the protrusion 120, the protective sleeve 13 still will not fall off. On this basis, after the probe 12 is worn with the protective sleeve 13, the probe 12 can be directly taken out. In this way, through reasonable dimension design, it is actually equivalent to realizing the automatic unlocking of the locking and limiting mechanism 200 through the change in the size of the edge 13a. Of course, after the probe 12 is worn with the protective sleeve 13, the locking and limiting mechanism 200 can also be switched to the unlocked state. For example, the third limiting member 230 can be rotated so that the third limiting member 230 leaves the first folding position, and the limitation of the protective sleeve 13 by the locking and limiting mechanism 200 can be released. The setting of the locking and limiting mechanism 200 can make the protective sleeve 13 less likely to fall off, and the overall device has stronger stability during use; moreover, the locking and limiting mechanism 200 does not make it more complicated to take out the probe 12 with the protective sleeve 13 worn. Whether it is through reasonable dimension design or rotating the third limiting member 230 to unlock the locking and limiting mechanism 200 to take out the protective sleeve 13 is very convenient.

[0054] Exemplarily, referring to Figure 6 and Figure 7, on the periphery of the third arc segment 231, a third auxiliary convex edge 233 may be convexly provided towards the base 100. The third auxiliary convex edge 233 may have a similar extension trend to that of the third arc segment 231. The third auxiliary convex edge 233 may be in the form of an arc-shaped protrusion. The third auxiliary convex edge 233 may be integrally formed with the third limiting member 230, or may be connected together in various forms such as welding after being separately processed. When the locking and limiting mechanism 200 is in the locked state, there may be a third gap in the form of a limiting ring edge between the third auxiliary convex edge 233 and the protruding portion 120. The setting of the third auxiliary convex edge 233, when the locking and limiting mechanism 200 is in the locked state, can make there be a gap between the third limiting member 230 and the base 100, and the operator can observe the state of the protective cover 13 in the gap, so as to avoid that the protective cover 13 is broken during the process of wearing the protective cover 13 on the probe 12 and cannot be discovered.

[0055] Exemplarily, referring to Figure 6 and Figure 7 , on the base 100, a support column 130 may be convexly provided along the first direction X. On the side of the third limiting member 230 towards the base 100, a third auxiliary support column 234 may be provided. When the locking and limiting mechanism 200 is in the locked state, the third auxiliary support column 234 may abut against the support column 130. When the third auxiliary support column 234 abuts against the support column 130, the third auxiliary support column 234 and the support column 130 as a whole can make the relative position between the third limiting member 230 and the base 100 more stable. The setting of the third auxiliary support column 234 and the support column 130 can also make the structure of the overall device more stable. Since there may be a gap between the third limiting member 230 and the base 100 for the operator to observe the state of the protective cover 13, the setting of the third auxiliary support column 234 and the support column 130 can also make this gap more stable. When the third limiting member 230 is located above the base 100, the base 100 can provide better support for the third limiting member 230 by abutting against the third auxiliary support column 234 through the support column 130.

[0056] In an embodiment not shown, the locking and limiting mechanism 200 may further include a fourth limiting member. The fourth limiting member may include a fourth arc segment and a second connection end opposite to the fourth arc segment. The second connection end may be rotatably connected to a side of the seat body 100 away from the first connection end 232, so that the fourth limiting member is rotatable relative to the seat body between a second folding position and a second opening position. The fourth limiting member may be similar to the third limiting member, and details thereof will not be described herein. Exemplarily, the fourth limiting member may be the same as the third limiting member 230, and the fourth limiting member and the third limiting member 230 may be symmetrically disposed on the seat body 100. It should be noted that when the locking and limiting mechanism 200 includes the third limiting member 230 and the fourth limiting member, the locking and limiting mechanism 200 is in a locked state when the third limiting member 230 is in the first folding position and / or the fourth limiting member is in the second folding position.

[0057] Among them, when the fourth limiting member is in the second folding position, the locking and limiting mechanism 200 can be in the locked state, the fourth limiting member can be in the second folding position, and the fourth arc segment can limit the protective sleeve 13 alone, or the fourth arc segment and the third arc segment 231 can surround and limit the protective sleeve 13. When the locking and limiting mechanism 200 is in the unlocked state, the fourth limiting member can be in the second open position. The second connecting end can be rotatably connected to the side of the seat body 100 away from the first connecting end 232 through a hinge structure or any other suitable form. Taking the fourth arc segment and the third arc segment 231 surrounding and limiting the protective sleeve 13 as an example for illustration. When the locking and limiting mechanism 200 is in the locked state, the third limiting member 230 is in the first folding position, the fourth limiting member is in the second folding position, and the fourth arc segment and the third arc segment 231 can surround and limit the protective sleeve 13. The fourth limiting member and the third limiting member 230 can be located on opposite sides of the seat body 100 respectively. When unlocking, the third limiting member 230 and the fourth limiting member can be flipped open to both sides respectively, so that the third limiting member 230 is in the first open position and the fourth limiting member is in the second open position; or at least one of the third limiting member 230 and the fourth limiting member 240 can be flipped, so that the third limiting member 230 is in the first open position and / or the fourth limiting member is in the second open position. The first folding position and the second folding position here are only for distinction and are not limited in any way; similarly, the first open position and the second open position are only for distinction and are not limited in any way. In such a probe protective sleeve wearing device 11, when the locking and limiting mechanism 200 is in the locked state, it can be that the third limiting member 230 is in the first folding position or the fourth limiting member is in the second folding position. Correspondingly, it can be that the third arc segment 231 or the fourth arc segment alone limits the protective sleeve 13, so as to meet the requirements of more application scenarios; when the locking and limiting mechanism 200 is in the locked state, it can also be that the third limiting member 230 is in the first folding position and the fourth limiting member is in the second folding position. Correspondingly, it can be that the fourth arc segment and the third arc segment 231 surround and limit the protective sleeve 13, which can further improve the stability of the limit on the protective sleeve 13. Similarly, through reasonable size design, it is possible to take out the probe 12 with the protective sleeve 13 worn without the locking and limiting mechanism 200 being in the unlocked state. That is to say, whether through reasonable size design or rotating at least one of the third limiting member 230 and the fourth limiting member 240, it is very convenient to unlock the locking and limiting mechanism 200 for the protective sleeve 13 and thus take out the protective sleeve 13.

[0058] Similarly, a third auxiliary convex edge 233 may be provided protruding toward the base 100 on the periphery of the third arc segment 231, and a fourth auxiliary convex edge may be provided protruding toward the base 100 on the periphery of the fourth arc segment. When the locking and limiting mechanism 200 is in the locked state, a fourth gap with a limiting ring edge may exist between the third auxiliary convex edge 233 and / or the fourth auxiliary convex edge and the protruding portion 120. A fourth gap may exist independently between the third auxiliary convex edge 233 or the fourth auxiliary convex edge and the protruding portion 120, or a fourth gap with a limiting ring edge 13a may exist between the third auxiliary convex edge 233 and the fourth auxiliary convex edge surrounding the protruding portion 120. The provision of the third auxiliary convex edge 233 and the fourth auxiliary convex edge may create a gap between the third limiting member 230 and the fourth limiting member 240 as a whole and the base 100 when the locking and limiting mechanism 200 is in the locked state, allowing the operator to observe the state of the protective cover 13 in the gap, so as to avoid failing to detect that the protective cover 13 is broken during the process of wearing the protective cover 13 on the probe 12.
