[0039] The utility model provides a protective cover for an ultrasonic transducer handle with switchable states.

[0040] Reference Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the protective cover of the utility model in a protective state. Figure 2 This is a schematic diagram of the structure of the first body of the protective cover of the utility model. Figure 3 It is a cross-sectional view of the second sleeve of the protective sleeve of the utility model.

[0041] In an embodiment of the utility model, the ultrasonic transducer handle includes a transducer assembly 210; the ultrasonic transducer handle protective cover 100 has a first accommodating cavity 1101 for accommodating a front end shell 211 of the transducer assembly 210 and a second accommodating cavity 121 for accommodating a rear end shell 211 of the transducer assembly 210, and the protective cover 100 is sleeved on the transducer assembly 210 through the first accommodating cavity 1101 and the second accommodating cavity 121.

[0042] The protective cover 100 in a technical solution of an embodiment of the utility model is provided with a first accommodating cavity 1101 and a second accommodating cavity 121, and is sleeved on the front end housing 211 of the transducer assembly 210 through the first accommodating cavity 1101, and is sleeved on the rear end housing 211 of the transducer assembly 210 through the second accommodating cavity 121. When the ultrasonic transducer handle falls accidentally, the front end of the transducer assembly 210 generally touches the ground. In this solution, the front end of the transducer assembly 210 is protected by the protective cover 100, which reduces the possibility of damage to the transducer assembly 210; even if the front end does not touch the ground, since the rear end of the transducer assembly 210 is also protected by the protective cover 100, both the front and rear ends of the transducer assembly 210 are protected by the protective cover 100, so the collision force received by the transducer assembly 210 when it falls is greatly reduced, thereby further reducing the possibility of damage to the transducer assembly 210.

[0043] In one embodiment, the protective cover 100 includes a first cover body 110 and a second cover body 120 , the first accommodating cavity 1101 is disposed in the first cover body 110 , and the second accommodating cavity 121 is disposed in the second cover body 120 .

[0044] Reference Figures 1 to 3In this embodiment, the protective cover 100 includes a first cover body 110 and a second cover body 120 which are separately arranged. The first cover body 110 protects the front end of the transducer assembly 210, and the second cover body 120 protects the rear end of the transducer assembly 210. The first cover body 110 and the second cover body 120 can be manufactured independently, which reduces the manufacturing difficulty of the protective cover 100. On the other hand, when the first cover body 110 or the second cover body 120 is damaged, it can be replaced separately without replacing the entire protective cover 100, thereby reducing the use cost of the protective cover 100. On the other hand, the first cover body 110 and the second cover body 120 can be manufactured from different materials according to the different protection requirements of the front and rear shells 211, so as to better balance the protection performance and manufacturing cost.

[0045] In one embodiment, the first housing 110 is movable relative to the second housing 120 or is detachably connected to the second housing 120 .

[0046] Reference Figure 1 and Figure 7 In this embodiment, the first sleeve 110 can be detachably connected to the second sleeve 120, so that the first sleeve 110 and the second sleeve 120 form a whole, which is convenient for storing and taking out the protective cover 100, and reduces the possibility of losing one of the first sleeve 110 and the second sleeve 120. After the first sleeve 110 and the second sleeve 120 are detached, the two can move relative to each other, which is convenient for setting the first sleeve 110 and the second sleeve 120 at both ends of the transducer assembly 210 on the one hand, and on the other hand, the protective cover 100 can be applied to transducer assemblies 210 of different lengths and sizes, thereby improving the adaptability of the protective cover 100.

[0047] In one embodiment, the protective cover 100 further includes a flexible or elastic connector 130 , which connects the first cover body 110 and the second cover body 120 ; the second cover body 120 is provided with a first receiving groove 122 , and the connector 130 can be partially received in the first receiving groove 122 .

[0048] Reference Figure 1 and Figure 4In this embodiment, the connecting piece 130 connects the first housing 110 and the second housing 120, so that the first housing 110 and the second housing 120 are connected as a whole through the connecting piece 130 regardless of whether they are separated, thereby further reducing the possibility of losing the first housing 110 and the second housing 120. Specifically in this embodiment, a protrusion is provided on the outer peripheral wall of the first housing 110, and a bayonet is provided on the protrusion. One end of the connecting piece 130 is fixed to the bayonet, and the other end of the connecting piece 130 is fixed to the outer peripheral wall of the second housing 120, so that the connecting piece 130 and the first housing 110 and the second housing 120 cannot be separated naturally. The connecting piece 130 is generally in the shape of a rope, a belt, a chain, etc., and can be made of a flexible material, such as fiber or plastic, etc. The connecting piece 130 can also be made of an elastic material, such as rubber or nylon, etc. Specifically in this embodiment, when the protective cover 100 is in the protection state, the distance between the first cover 110 and the second cover 120 is longer; when the protective cover 100 is in the anti-lost state, the distance between the first cover 110 and the second cover 120 is shorter; the length of the connector 130 made of flexible material can be designed with reference to the distance in the protection state; when the protective cover 100 is in the anti-lost state, the connector 130 is wrapped around the periphery of the first cover 110 or the periphery of the second cover 120; the length of the connector 130 made of elastic material can be designed with reference to the distance in the anti-lost state; when the protective cover 100 is in the protection state, the connector 130 is elastic and can be stretched.

[0049] Reference Figure 5In this embodiment, the distance between the first sleeve 110 and the second sleeve 120 will change when they move relative to each other. In order to ensure that the connecting piece 130 meets the usage requirements, the length of the connecting piece 130 is likely to be designed to be longer. Therefore, a first receiving groove 122 is provided on the second sleeve 120. The excessively long connecting piece 130 can be wrapped around the inside of the first receiving groove 122, thereby preventing the excessively long connecting piece 130 from being entangled or hooked with other objects, thereby improving the safety of the surgical environment and the neatness of the protective cover 100. Specifically in this embodiment, after the first sleeve 110 and the second sleeve 120 are sleeved on both ends of the transducer assembly 210, by winding the connecting piece 130 inside the first receiving groove 122, the length of the connecting piece 130 is close to the distance between the first sleeve 110 and the second sleeve 120, and the first sleeve 110 and the second sleeve 120 are restricted by the connecting piece 130 and cannot move away from each other, so that the first sleeve 110 and the second sleeve 120 cannot be separated from the transducer assembly 210, thereby ensuring the protective effect of the protective cover 100 on the transducer assembly 210. Similarly, a second receiving groove can also be provided on the first sleeve 110, and the excessively long connecting piece 130 can be wound inside the second receiving groove, thereby preventing the excessively long connecting piece 130 from being entangled or hooked with other objects, thereby improving the safety of the surgical environment and the neatness of the protective cover 100.

[0050] In one embodiment, the ultrasonic transducer handle further includes a cable 220 connected to the rear portion of the transducer assembly 210 , and the second sleeve 120 may also be sleeved on the cable 220 .

[0051] Reference Figures 7 and 8 In this embodiment, during the use of the ultrasonic transducer handle, the protective cover 100 is not required. At this time, the second cover 120 is connected to the cable 220 at the rear of the transducer assembly 210, making it difficult for the second cover 120 to be separated from the cable 220, thereby reducing the possibility of losing the second cover 120. The second cover 120 is sleeved on the outside of the cable 220 through the second accommodating cavity 121, making the connection between the second cover 120 and the cable 220 more secure. In the case of non-manual disassembly or damage, the second cover 120 cannot be separated from the cable 220, further reducing the possibility of losing the second cover 120. Specifically in this embodiment, the first cover 110 and the second cover 120 are detachably connected, making it difficult for the entire protective cover 100 to be separated from the cable 220, thereby reducing the possibility of losing the entire protective cover 100. Among them, the first cover 110 and the second cover 120 can be detachably connected by various methods such as snap-on, screw locking, or magnetic attraction. Specifically in this embodiment, the first cover 110 and the second cover 120 are detachably connected by socket connection, which is convenient for disassembly and assembly, and improves the aesthetics of the protective cover 100 in the anti-lost state.

[0052] In one embodiment, the protective cover 100 has a protective state and an anti-lost state, and can be switched between the protective state and the anti-lost state; the second accommodating chamber 121 includes a first sub-channel 1211 and a second sub-channel 1212 that are connected to each other, and the second cover 120 is sleeved on the outer wall of the rear end shell 211 of the transducer assembly 210 through the first sub-channel 1211 to put the protective cover 100 in the protective state, and the second cover 120 is sleeved on the outside of the plug 221 provided on the cable 220 through the second sub-channel 1212 to put the protective cover 100 in the anti-lost state.

The first sleeve 110 and the second sleeve 120 are sleeved on both ends of the transducer assembly 210 to protect the transducer assembly 210, so that the protective cover 100 is in a protective state; when the transducer assembly 210 needs to be used, the first sleeve 110 and the second sleeve 120 are separated from the transducer assembly 210, and the second sleeve 120 is sleeved on the cable 220. The first sleeve 110 and the second sleeve 120 are detachably connected, so that the entire protective cover 100 is difficult to be separated from the cable 220, thereby reducing the possibility of losing the protective cover 100 and putting the protective cover 100 in an anti-lost state.

[0054] Reference Figure 3 and Figure 8 In this embodiment, the second accommodating cavity 121 includes a first sub-channel 1211 and a second sub-channel 1212 that are connected to each other. When the protective cover 100 is in the protection state, the second cover body 120 is sleeved on the outside of the transducer assembly 210 through the first sub-channel 1211; one end of the cable 220 is connected to the rear of the transducer assembly 210, and the other end is provided with a plug 221. When the protective cover 100 is in the anti-lost state, the second cover body 120 is sleeved on the outside of the plug 221 of the cable 220 through the second sub-channel 1212, so that the second cover body 120 is fixed to the plug 221, and at this time, the first cover body 110 is detachably connected to the second cover body 120, so that the entire protective cover 100 is fixed to the plug 221, so that the protective cover 100 in the anti-lost state is prevented from sliding along the cable 220 or shaking on the cable 220, thereby avoiding the interference of the protective cover 100 with the surgical operation, making it more convenient for the user to hold the transducer assembly 210 for surgery, thereby improving the safety of the surgical process.

[0055] In this embodiment, the first sleeve 110 and the second sleeve 120 are both made of elastic materials, such as rubber or plastic, which can withstand high-temperature steam sterilization and can play a good buffering role when falling, thereby protecting the transducer assembly 210; on the other hand, the friction between the first sleeve 110 and the transducer assembly 210, between the second sleeve 120 and the transducer assembly 210, and between the second sleeve 120 and the plug 221 are all relatively large, which can effectively ensure that the protective cover 100 is maintained in a protective state or an anti-lost state.
