Referring to fig. 3 to 8, fig. 3 is a schematic structural view of a dental elbow pad with an anti-fouling cover according to a first embodiment of the present utility model; FIG. 4 is a cross-sectional view taken in the direction A-A of FIG. 3; FIG. 5 is a schematic view of an anti-fouling cover according to a first embodiment of the present utility model; FIG. 6 is an axial cross-sectional view of FIG. 5; FIG. 7 is a radial cross-sectional view of FIG. 5; fig. 8 is a schematic structural view of a dental elbow handset with an anti-fouling cover according to a second embodiment of the utility model.

The utility model provides an anti-fouling cover which is applied to a motor 2 of a dental handpiece and comprises a cover body, wherein the cover body is of a cylindrical structure with two open ends, and the cover body is sleeved and fixed on the motor 2. In particular, the cover body and the motor 2 can be fixedly connected in a screw, a buckle or a magnetic attraction mode. The dental handpiece 1 includes a handpiece on which a needle is provided, and a motor 2. The dirty liquid easily enters the movement from the shell of the motor 2, and finally the motor 2 is scrapped, so that the problem that the anti-fouling cover actually solves is that the liquid is prevented from entering the movement of the motor 2.

The scheme provides an antifouling cover, uses a cover body that can carry out repeated disinfection to replace operation disinfection piece of cloth 3, and this antifouling cover's structural design is simple, dismouting operation uses portably. Because the cover body is sleeved and fixed on the motor 2, the motor 2 and the dirty liquid can be isolated during normal operation, the cover body is not required to be removed during the change of the bending machine, and the motor 2 can still effectively isolate the motor 2 and the dirty liquid.

In one embodiment, the housing is removably attachable to the motor 2 for replacement or cleaning.

In a specific embodiment, the inner wall of the cover body close to the output end of the motor 2 is provided with a sealing structure, wherein the sealing structure is tightly matched with the outer wall of the motor 2 so as to realize detachable fixed connection. The sealing structure is mainly utilized to realize that the cover body is close to the output end of the motor 2 and is in sealing contact with the outer wall of the motor 2, so that the motor 2 and dirty liquid can be isolated during normal operation, and in the operation using process, the bending machine can be conveniently and rapidly replaced, thereby effectively realizing that the motor 2 and the dirty are isolated during the operation without influencing the replacement of the bending machine.

In a specific embodiment, as shown in fig. 3 and fig. 4, when the flexible disinfection cover 4 provided by the utility model is used, the flexible disinfection cover 4 is sleeved on the motor 2, and is provided with the flexible sealing structure 41, and the flexible sealing structure 41 is in sealing contact with the outer wall of the motor 2 to play a role in sealing, so that the contact of dirty liquid with the motor 2 can be effectively prevented. And, because of its flexibility, can be deformed, it can be effectively fixed to the motor 2 without having to have a structure similar to the tightening rope 31. When the structure is used, the flexible disinfection cover 4 is not required to be removed, and the bending machine can be replaced for use, so that the structure is convenient and quick.

The flexible disinfection cover 4 is made of flexible materials such as silica gel, rubber and the like, has flexibility and elasticity after being molded, is applicable to the condition that the size of the motor 2 is equal to or slightly larger than that of the flexible disinfection cover 4, and the flexible disinfection cover 4 is wrapped on the motor 2, can generate certain deformation and can restore the original shape after being removed.

The flexible sealing structure 41 may be a flexible sealing ring, and its material also includes, but is not limited to, flexible materials such as silica gel, rubber, etc.

On the basis of the above specific embodiment, as shown in fig. 5, in addition to the flexible sealing structure 41, the outer surface of the flexible sterilization cover 4 is further provided with anti-slip patterns 42, so that the motor 2 can be well held under the condition of wrapping the flexible sterilization cover 4.

In addition, as shown in fig. 6 and 7, the supporting ribs 43 are further disposed in the flexible sterilizing cover 4, so that the structure of the flexible sterilizing cover 4 is more stable, and when the flexible sterilizing cover 4 is sleeved on the motor 2, the inner wall of the flexible sterilizing cover is not completely attached to the motor 2, so that the flexible sterilizing cover 4 can be detached easily when the flexible sterilizing cover 4 needs to be detached. If the support ribs 43 are not provided, the flexible sterilizing cover 4 is completely attached to the motor 2 when the flexible sterilizing cover is detached, and negative pressure is formed inside the flexible sterilizing cover, so that the detachment difficulty is extremely high.

In another embodiment, based on similar principles, the housing structure may also be formed as a rigid sterilization housing 5, as shown in fig. 4 and 8, and then a flexible sealing structure 51 may be provided thereon for sealing.

In addition, a fixing structure 52 can be added on the rigid sterilizing cover 5 to effectively fix the sterilizing cover on the motor 2. The bending machine is replaced in the operation process, and the fixing structure 52 can be replaced conveniently and rapidly without being removed. The securing structure 52 includes, but is not limited to, a set screw structure. The fixed structure 52 may be provided at any position of the motor 2, and in particular, may be provided at an opposite end of the output end of the motor.

When the fixing structure 52 is a fastening screw, a screw hole for connection with the fastening screw is provided on the motor 2.

The working principle of the antifouling cover provided by the scheme is as follows:

the conventional surgical towel 3 is limited to a fixed manner in use, and is not convenient enough and the motor 2 is at risk of being polluted when the bending machine needs to be replaced in some complex application scenes.

The anti-fouling cover provided by the utility model can be effectively fixed on the motor 2 without other fixing modes because of the flexible material of the flexible disinfection cover 4; for the rigid sterilizing cover 5, the fixing mode is that the sterilizing cover is not required to be dismantled when the bending machine is replaced, and the sterilizing cover is convenient to use.

The utility model does not limit the material of the flexible disinfection cover 4 further, is flexible, has certain deformability, resists high-temperature disinfection and has good biocompatibility. The utility model does not limit the material of the rigid sterilizing cover 5 further, and the utility model has high temperature resistance, sterilization and good biocompatibility. The fixing mode of the cover body and the motor 2 is not limited, and the cover body and the motor 2 can be detachably fixed.

The flexible sterilization cover 4 and the rigid sterilization cover 5 can be sterilized by high-temperature high-pressure steam like the well-known dental curve hand piece 1 and the operation sterilization towel 3 so as to avoid cross infection among different operations.

In addition, in this embodiment, there is also provided a medical apparatus including the dental handpiece 1 and the anti-fouling cover as described above, the anti-fouling cover being used to cover the motor 2 of the dental handpiece 1.

The medical device has the anti-fouling cover, so the medical device has the beneficial effects brought by the anti-fouling cover, and the description is omitted herein.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
