[0043] As shown in Figures 1 to 4 The anti-collision structure 100 provided by the embodiment of the application includes a bottom plate 10, a cover plate 20, and a switch assembly 30, the switch assembly 30 is arranged between the bottom plate 10 and the cover plate 20; wherein the switch assembly 30 includes a trigger switch 31, a first conductive sheet 32, and a second conductive sheet 33, the trigger switch 31 is electrically connected to the first conductive sheet 32 and the second conductive sheet 33 respectively, the first conductive sheet 32 is installed on the bottom plate 10, and the second conductive sheet 33 is installed on the cover plate 20. So that the cover plate 20 can control the contact / separation between the second conductive sheet 33 and the first conductive sheet 32; when the second conductive sheet 33 is in contact with the first conductive sheet 32, the trigger switch 31 is powered on and generates a feedback signal. Here, the trigger switch 31 can be triggered by detecting the current and voltage in the circuit through which the first conductive sheet 32 and the second conductive sheet 33 are conducted, and the feedback signal generated by the trigger switch 31 can finally be displayed in the form of light emission, sound emission, etc. according to the use requirements, which will not be expanded here.
[0044] As can be seen from the above, the anti-collision structure 100 can use the feedback signal generated by the trigger switch 31 to reflect that the cover plate 20 of the anti-collision structure 100 is subjected to a collision, so that the treatment risk and equipment damage caused by the collision when the target object enters the medical device body 200 can be effectively distinguished and excluded; in addition, the anti-collision structure 100 not only can realize the detection of different collisions of the medical device body 200, but also can be adapted to different shapes and different positions of the medical device body 200, so that the anti-collision structure 100 has a wide range of adaptation.
[0045] As shown in Figure 1 , Figure 4 and Figure 5As shown in the figure, in some embodiments, the cover plate 20 comprises a guide protrusion 21 which is arranged through the bottom plate 10; in addition, the anti-collision structure 100 further comprises a limiting piece 211 which is mounted on the portion of the guide protrusion 21 which passes through the bottom plate 10 and abuts against the bottom plate 10, for limiting the cover plate 20 on the bottom plate 10. In this way, on the one hand, the guide protrusion 21 and the bottom plate 10 are inserted and fitted, which can guide the movement of the cover plate 20 relative to the bottom plate 10; on the other hand, the limiting piece 211 and the bottom plate 10 abut, which can realize the assembly limiting of the cover plate 20 on the bottom plate 10, so as to facilitate the assembly of the cover plate 20 on the bottom plate 10. Here, the limiting piece 211 is configured as a snap spring, a screw, etc.
[0046] As shown in the figure, Figure 1 , Figure 5 in some embodiments, the number of guide protrusions 21 is multiple, and the multiple guide protrusions 21 are arranged along the length direction of the cover plate 20, so that the multiple guide protrusions 21 can simultaneously guide the movement of the cover plate 20 relative to the bottom plate 10, which can improve the smoothness of the movement of the cover plate 20. Here, the guide protrusion 21 is connected with the cover plate 20 as a whole.
[0047] As shown in the figure, Figure 1 in some embodiments, the number of switch assemblies 30 is multiple, and the multiple switch assemblies 30 are arranged along the length direction of the cover plate 20, so that the trigger switches 31 on the multiple switch assemblies 30 can all be triggered due to the touch of the cover plate 20, which can improve the sensitivity of the anti-collision structure 100 assembled on the medical equipment body 200 for collision detection.
[0048] As shown in the figure, Figures 1 to 4 in some embodiments, the trigger switch 31 and the first conductive sheet 32 are electrically connected by a first wire 34, and the trigger switch 31 and the second conductive sheet 33 are electrically connected by a second wire 35. In this way, by using the structural characteristics of the first wire 34 and the second wire 35, the assembly position of the trigger switch 31 in the anti-collision structure 100 can be arbitrarily adjusted according to requirements, so as to facilitate the assembly of the trigger switch 31.
[0049] As shown in the figure, Figure 1 , Figure 2 and Figure 4As shown in the drawings, in some embodiments, the first conductive sheet 32 and / or the second conductive sheet 33 comprises an elastic protrusion 321; when the second conductive sheet 33 contacts the first conductive sheet 32, the elastic protrusion 321 is compressed and elastically deformed. That is, when the second conductive sheet 33 is driven by the cover plate 20 to contact the first conductive sheet 32, the elastic deformation of the elastic protrusion 321 can buffer the contact between the first conductive sheet 32 and the second conductive sheet 33, thereby preventing the first conductive sheet 32 and the second conductive sheet 33 from being structurally damaged due to contact, and prolonging the service life. Here, the elastic protrusion 321 is provided on the first conductive sheet 32. It can be understood that in other embodiments, the elastic protrusion can also be provided on the second conductive sheet 33, or both the first conductive sheet 32 and the second conductive sheet 33 are provided with the elastic protrusion.

That is, after the cover plate 20 is removed from the external force, the cover plate 20 can be reset under the elastic pushing of the elastic member 40, and the automatic rebound of the cover plate 20 is realized, so that the detection of the next collision of the cover plate 20 is realized, so that the anti-collision structure 100 can be used for repeated detection of collision. Here, the elastic member 40 is configured as a spring and is sleeved on the guide protrusion 21. It can be understood that in other embodiments, the elastic member 40 can also be configured as a rubber sleeve or other accessories with high elasticity.

[0053] In addition, the application also provides a medical device, which comprises a medical device body 200 and the above-mentioned anti-collision structure 100, and the anti-collision structure 100 is mounted on the medical device body 200.
[0054] As shown in Figure 6 In some embodiments, the anti-collision structure 100 is detachably connected to the medical device body 200. In this way, when the anti-collision structure 100 is damaged, only the anti-collision structure 100 needs to be replaced, without affecting the medical device body 200, thereby reducing the maintenance cost of the anti-collision structure 100.

[0055] As shown in Figure 6 In some embodiments, the medical device body 200 is internally formed with a passage hole 201 for the target object to enter and exit, and the anti-collision structure 100 is arranged at the periphery of the passage hole 201 and extends along the axial direction and / or the radial direction of the passage hole 201. In this way, when the anti-collision structure 100 is assembled to the medical device body 200, the radial and / or axial collision detection of the passage hole 201 can be performed to meet different use requirements.
[0056] In some embodiments, the anti-collision structure 100 is left-right symmetrical with respect to the center line of the passage hole 201, so that the anti-collision structure 100 is arranged on the left and right sides of the medical device body 200 where collisions are more likely to occur. It can be understood that in other embodiments, the anti-collision structure 100 can also be in the form of a circular ring.
