Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] The present invention provides such as Figure 1-5 A medical large-scale bone cement filler is shown, which includes a tube 1, a tube sleeve 2, a first piston 3 and a piston rod 4. The tube sleeve 2 is threaded and fixed on the end of the tube 1, and the end of the tube sleeve 2 has a The material hole, and the surface of the discharge hole is threaded and fixedly connected with the mud outlet pipe 5, and the inner side of the end of the bobbin tube 1 i...

The invention discloses a medical large bone cement filler comprising a bobbin, a sleeve, a first piston and a piston rod. The sleeve is in threaded connection with and fixed at the end part of the bobbin; a discharging hole is formed in the end of the sleeve; and a sludge discharging pipe is fixedly connected to the surface of the discharging hole in a threaded mode. A pressure buffering device is connected to the inner side of the end of the bobbin in a threaded mode and comprises a fixing shell; a stop block is fixedly arranged on the surface of one side of the fixing shell; multiple through holes are formed in the surface of the stop block; and a telescopic sleeve is fixedly connected to the middle of one side of the stop block. A sealing block is driven to return to the original position through deformation recovery of the spring in the pressure buffering device and is abutted against the surface of an annular protruding block, so that excessive overflowing of bone cement is avoided and thus the influence on an operation is avoided; the pain of a patient can be reduced; and blood and body fluid can be sucked into a liquid suction pipe through a liquid guide pipe by arranging the liquid suction pipe on the side wall of the bobbin, so that the operation effect is improved.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a large medical bone cement filler. Background technique [0002] Vertebral compression fracture is the most common complication in patients with osteoporosis. The previous open surgical treatment was traumatic and complicated. Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are a new type of minimally invasive surgery that has developed rapidly in spinal surgery in recent years. The mechanical stability of the diseased vertebral body is enhanced by expanding the balloon and then injecting bone cement, artificial bone and other fillers. Clinical application has confirmed its stable, reliable, rapid and effective therapeutic effect with few complications. [0003] In minimally invasive surgery, it is necessary to use a filler to push in the bone cement. Usually, the capacity of the bone cement filler is relatively small. Overflow will not only af...
