Manual bone grinding machine convenient to use

Abstract

The invention discloses a manual bone grinding machine convenient to use. The machine comprises a base, an upper cover, a bone grinding roller assembly and a bone receiving box, wherein the upper cover is arranged above the base, a feeding port is formed in the top of the upper cover, one side of the upper cover is connected with one side of the base in a pivoted mode, the other side of the uppercover is connected with the other side of the base through a bolt assembly, the bone grinding roller assembly is arranged in a containing cavity formed by the upper cover and the base, the bone receiving box is arranged in the bone grinding roller assembly in a drawable mode, the bone grinding roller assembly comprises an outer roller, a plurality of discharging holes are formed in the circumferential face of the outer roller, and bone grinding blades are arranged on one side of each discharging hole. According to the machine, the bone grinding hole diameter can be adjusted through the bone grinding roller assembly, so that bone grains with different particle sizes are prepared, the requirements of different operations or different bone grafting parts for different bone diameters are met,and the work which can be completed by multiple devices can be completed through one device.

Description

Technical field [0001] The present invention relates to the field of medical devices, and in particular, to a manual manual bone diagram for easy use. Background technique [0002] The mannels are commonly used in orthopedic surgery. The main role is to pulverize the human body or artificially pulverized into different particle sizes in order to implant the human body needs to be bone. The current grinding bone machine is mainly divided into two categories of electric and manual, including high cost, large size, and use occasion, and cannot be cleaned at will after use, otherwise it will damage the internal electrical components; Although the bone machine is simple, the cost is low, the use occasion is limited, but there are still some problems, such as: [0003] 1. The existing manual manual bone machine can only process one dimensional bone granules, which cannot meet the need for bone grain in different particle sizes, when the bone granules are needed, can only be used The mo...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing manual bone grinder can only process bone particles of one size and particle size, which cannot meet the needs of different operations for bone particles of different particle sizes. When it is necessary to prepare bone particles of various particle sizes, only different Model bone grinder, so the operation is not convenient enough;

[0004] 2. After the bone is crushed, it is not convenient to collect the crushed bone particles, and the equipment needs to be disassembled;

[0005] 3. The parts of the existing manual bone grinding machine are usually connected by welding or bolts, so it is inconvenient to clean. Either the equipment needs to be disassembled for cleaning with the help of tools, or because the welding is not easy to disassemble, there are cleaning dead ends, which is not hygienic enough
