  • Patent number: 11937864
    Abstract: The invention relates to a magnetic-navigation joint type puncture needle which comprises a head section and needle sections, wherein, the head section is made of stainless steel material with high magnetic conductivity and is connected with the following needle sections coaxially mounted with the head section through a flexible joint; two needle sections are also coaxially connected with each other through a flexible joint; the needle sections are made of non-magnetic stainless steel material; the flexible joints adopts serpentine tubes formed by melting and engraving cobalt-chromium alloy through laser; and both the head section and the needle sections can be bent, but the flexibility of the head section and that of the needle sections are smaller than the flexibility of the flexible joints.

  • Patent number: 11304739
    Abstract: The present disclosure relates to systems and methods for mixing and injecting fluid treatment, such as cement to treat bone or hard tissue. In some embodiments, a mixing apparatus may facilitate mixing within a syringe. Additionally, the syringe may be configured to extract bone cement from a cement mixer. A syringe for mixing and injecting cement may include a detachable handle that may be detached after extracting bone cement from a mixer to facilitate coupling to a high-pressure syringe for injection.

  • Patent number: 8523871
    Abstract: Systems and methods for delivering bone cement into a bone can include a handle body defining a flow path, a thermal emitter in the handle body to apply energy to bone cement passing through the flow path, a source of bone cement and an injection cannula. The cannula can be in communication with the flow path such that inserting the cannula into a bone can allow a flow of bone cement therethrough to an opening at a distal end of the cannula. Other systems and methods for delivering bone cement into a bone can include an injector body with a handle portion, and a cannula, a bone cement container, a low pressure drive mechanism configured to effect a flow of bone cement from said container to the injector body and a high pressure drive mechanism configured to effect a flow of bone cement through the injector body into the bone.
