A pusher for implant bone material

Abstract

The invention discloses a pusher for a bone grafting material, which relates to the technical field of medical equipment. The pusher comprises a multi-linkage mechanism; the outer side surface of themulti-linkage mechanism is connected with a drainage pipe; the top end of the drainage tube is communicated with a funnel; the top end of the funnel is sleeved with a sealing end cover; the upper partof the outer side surface of the drainage pipe is fixedly sleeved with an annular extrusion airbag; the top end of a silicone tube bag is communicated with a connecting tube; the top end of the connecting tube is communicated with a connecting airbag; a mounting notch is respectively correspondingly matched with the position of the silicone tube bag; an elastic plate is respectively fixedly connected with the silicone tube bag; a flexible auger blade is installed in the drainage tube in a rotating manner; and the middle part of the auger blade is fixedly provided with a steel wire rope The pusher has the beneficial effects that the multi-linkage mechanism is used for supporting the drainage tube, and the drainage tube is adjusted, so that the bone grafting operation is more flexible and more convenient; and the bone powder is transported by virtue of the auger blade, so that the blockage caused by the accumulation of the bone powder can be avoided, the operation is smoother, the extrusion area is increased by virtue of an elastic plate, and the compaction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] Bone grafting is to use surgery to transplant bone tissue to the bone defect in the patient's body, which needs to be strengthened or fused. Traditionally, when performing bone grafting, medical staff usually use pipelines to transfer bone tissue such as bone powder to the desired bone grafting site. However, the pipes traditionally used are made of rigid materials and cannot be bent, which causes certain limitations in use. When transferring bone powder, bone powder is easy to accumulate in the pipe, causing blockage, so it needs to be fiddled with tools to make it unblocked. Increase the labor intensity of medical staff and reduce the bone grafting efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pusher for bone graft materials in view of the above existing technical deficienci...
