Splash-proof bone grafting device for orthopedic surgery and using method of bone grafting device

Abstract

The invention relates to the technical field of medical apparatuses, and in particular to a splash-proof bone grafting device for an orthopedic surgery and a using method of the bone grafting device.The bone grafting device comprises a placing drum, a pressing rod and a blanking drum, wherein the placing drum is screwed with the blanking drum; a knob handle, which rotates around the pressing rod,sleeves the top of the pressing rod; a pressing plug, which is matched with the inner diameter of the placing drum, is arranged at the bottom of the pressing rod; a stable pressing mechanism is arranged on the knob handle; a round sleeve movably sleeves the placing drum; a handle is arranged on the round sleeve; and a sealing structure, which is matched with the pressing plug, is arranged in theblanking drum. The bone grafting device provided by the invention is simple in structure, convenient to operate and is safe and reliable, and the bone grafting device has a function of preventing splashing of bone chips; the bone grafting surgery can be easily and stably completed; the feeling of being painful of a patient can be avoided since additional impact force is avoided in a surgery process; and moreover, the bone grafting device has the characteristics of being stable in entire surgery process, conducive to implementation of bone grafting and capable of improving surgery efficiency.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a splash-proof bone grafting device for orthopedic surgery and a use method thereof. Background technique [0002] At present, bone grafting methods are often used to treat patients with bone defects or remove necrotic parts in orthopedic surgery. The usual surgical methods include drilling holes by the surgeon, and then using forceps to implant artificial bone, allogeneic bone or autogenous bone, or using a funnel The method of bone grafting with bone grafting rod. [0003] For example, an orthopedic splash-proof bone graft with the authorized announcement number CN207341778U (hereinafter referred to as plan A), the above plan A is to press the artificial bone, allogeneic bone or autogenous bone through the compaction block to the bone where the bone is implanted. However, the above solution A cannot keep the extrusion at a uniform speed during the process of extruding the art...

AI Technical Summary

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
