Bone cement stirring and filling device

Abstract

The invention discloses a bone cement stirring and filling device. The bone cement stirring and filling device comprises a stirring device, a filling device and a water injection component, wherein the bottom of the stirring device is connected to the filling device; the water injection component is arranged at one side of the stirring device; the stirring device comprises a first cylinder; a necking portion is arranged at the bottom of the first cylinder; the filling device comprises a second cylinder; a steel wire filter screen is fixed inside the second cylinder through a bolt; the inner wall of the steel wire filter screen is in slip connection with a piston; the top of the second cylinder is movably connected to a screw through a bearing; one end of the screw is connected to a rotaryknob; a screw hole is formed in the piston; the screw is in threaded connection with the screw hole; the necking portion passes through the outer wall of the top of the second cylinder; the piston isannular and is connected to a movable baffle plate correspondingly through a hinge; and the movable baffle plate is circular. The bone cement stirring and filling device has the characteristics of time and labor saving and a good stirring effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone cement stirring and filling device. Background technique [0002] Bone cement is a common name for bone cement. Bone cement is a medical material used in orthopedic surgery. Some of its physical properties and appearance and properties after solidification are quite similar to white cement for construction and decoration. Bone cement consists of a white powder and a colorless, pungent-smelling liquid two-part formulation. [0003] The mixing and filling process of the existing bone cement is completed on two instruments respectively. After the mixing is completed, the bone cement needs to be separately pulled out into the filling device to fill the bones of the human body. This process consumes a lot of time for doctors. The treatment process is undoubtedly harmful; the existing bone cement stirring shaft is only one-way stirring, although the direction of rotatio...

Problems solved by technology

[0003] The mixing and filling process of the existing bone cement is completed on two instruments respectively. After the mixing is completed, the bone cement needs to be separately pulled out into the filling device to fill the bones of the human body. This process consumes a lot of time for doctors. The treatment process is undoubtedly harmful; the existing bone cement stirring shaft is only one-way stirring, although the direction of rotation can be changed, but because the bone cement is relatively viscous, the fibers cannot be cut off, and the stirring effect is not good; in addition, the bone cement stirring Finally, it is necessary to squeeze out excess water to ensure that it will not cause water seepage when injected into the wound surface of the patient's body, so as to ensure the dryness of the wound
