Description

Bone meal collector

Technical Field

The utility model relates to the technical field of medical equipment, more specifically the bone meal collector that can use in operations such as otology that says so relates to one kind.

Background

In ear or tooth surgery, it is often necessary to remove or aspirate surgical waste fluids using a negative pressure suction device. Since the waste surgical fluid often contains a large amount of blood clots and bone debris powder,not only the suction apparatus is easy to be blocked, but also the bone fragment crushing waste liquid with certain value is discarded, thus being easy to cause waste. At present, the traditional bone meal collecting method often leads to bone meal loss due to excessive flushing or suction, and the collection process needs to repeatedly suspend the work of an electric drill and use a stripper to gather together and remove bone fragments, so that the collection efficiency is not high. And commercial bone meal collectors, such as Sheehy: (

US) or Moffat-Robinson (

Uk) can overcome these disadvantages but are expensive.

Therefore, how to provide a simple and economical bone meal collector, which can significantly improve the quality and efficiency of bone meal collection during surgery compared with the conventional method, is an important research topic for those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the above-mentioned technical problem among the prior art to a certain extent at least.

Therefore, the utility model aims to provide a bone meal collector, which comprises a collector main body and a pusher,

the collector main body comprises a cylindrical collecting cavity, a water inlet and a water outlet are respectively arranged at two ends of the collecting cavity, the water inlet is hermetically and detachably connected with a water inlet pipe, the water outlet is hermetically and detachably connected with a water outlet pipe, the water inlet pipe and the collecting cavity can rotate relatively, and the water outlet pipe and the collecting cavity can also rotate relatively; a filtering device is arranged in the collecting cavity and close to the water outlet, the filtering device comprises a circular ring with a certain thickness and a filtering net sleeved on the circular ring, an elastic rope playing a role of fastening the ring sleeve is fixed at the edge of the filtering net, and the circular ring is detachably connected to the inner wall of the collecting cavity;

the pusher comprises a circular pushing plate and a pushing rod vertically fixed on the pushing plate, the overall outer diameter of the pushing plate is slightly smaller than the inner diameter of the collecting cavity, so that the pushing rod can push the pushing plate to move freely in the collecting cavity, and gaps between the pushing plate and the collecting cavity can also be minimized.
