Anti-spattering bone grafting instrument and using method thereof

Abstract

The invention relates to the technical field of medical instruments, in particular to an anti-spattering bone grafting instrument and a using method thereof. The instrument comprises a placing tube, atamping rod and a discharging tube, the placing tube is screwed to the discharging tube, the top of the tamping rod is sleeved with a knob handle which rotates around the top of the tamping rod, themiddle of the knob handle is sleeved with an auxiliary rotating sleeve ring, the bottom of the tamping rod is provided with a tamping plug which matches with the inner diameter of the placing tube, astable tamping mechanism is installed on the knob handle, a handle is installed on a circular sleeve, and a sealing structure which matches with the tamping plug is arranged in the discharging tube. The anti-spattering bone grafting instrument has the advantages of simple structure, convenient operation, safety, reliability and broken bone spattering resistance, bone grating operation can be smoothly and stably completed, a handle allows the sleeve ring to be rotated in the placing tube in a more labor-saving way, there exits no additional impacting force in the operation process, the sense ofpain of a patient is not caused, the whole operation process of the bone grating instrument is stable to facilitate bone grating, and the operational efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a splash-proof bone grafting device and a method for using the same. Background technique [0002] At present, in orthopedic surgery, bone grafting is often used when treating patients with bone defects or removing necrotic parts. The usual surgical methods are to rely on the surgeon to drill a hole, and then use forceps to implant artificial bone, allogeneic bone or autologous bone, or use a funnel Bone grafting with the method of bone grafting stick. [0003] For example, the authorized announcement number is CN207341778U, a kind of orthopedic splash-proof bone grafting device (hereinafter referred to as plan A), the above-mentioned plan A is to press artificial bone, allogeneic bone or autologous bone into the bone by compacting block. However, the above scheme A cannot keep the extrusion at a uniform speed during the extrusion process of artificial bone, allogeneic b...

Problems solved by technology

[0003] For example, the authorized announcement number is CN207341778U, a kind of orthopedic splash-proof bone grafting device (hereinafter referred to as plan A), the above-mentioned plan A is to press artificial bone, allogeneic bone or autologous bone into the bone by compacting block. However, the above scheme A cannot keep the extrusion at a uniform speed during the extrusion process of artificial bone, allograft bone or autologous bone, which may lead to uneven extrusion strength, resulting in uneven compaction and prolonging the operation time

[0004] For example, an orthopedic splash-proof bone graft with the authorized announcement number CN205667571U (hereinafter referred to as plan B), and a splash-proof bone graft with the authorized announcement number CN202376207U (hereinafter referred to as plan C), the above-mentioned plan B and plan C can be realized The bone is implanted with new bone, but there are the following same problems: it is necessary to use a tamping rod to pound back and forth in the funnel to implant the new bone, so that the patient will feel pain due to the impact force during the pounding process, and Causes the instability of the whole bone graft, which is not conducive to bone grafting
