Abstract

The invention provides a disposable intraoperative bone powder collector, which relates to the field of medical equipment, and comprises a collecting container, a negative pressure connecting pipe and a middle ear aspirator connecting pipe, wherein a detachable end cover is arranged on one end of the collecting container and is communicated with the middle ear aspirator connecting pipe; a middle ear aspirator connector is arranged on one end, far away from the end cover, of the middle ear aspirator connecting pipe; the other end of the collecting container is communicated with the negative pressure connecting pipe; a negative pressure aspirator connector is arranged on one end, far away from the collecting container, of the negative pressure connecting pipe; a filter device is arranged in the collecting container and is connected with the inner wall of the collecting container. The disposable intraoperative bone powder collector provided by the invention solves the technical problems of heat injury easily caused on tissues, poorer local hemostatic effect, non-ideal surgery cleanliness degree, waste of healthy bone powder and poor collecting effect in the prior art.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable intraoperative bone powder collector. Background technique [0002] The surgery on the middle ear, mastoid, and oral and maxillofacial parts is a delicate minimally invasive surgery. The surgical approach needs to be drilled through the surface of the bone to enter the surgical cavity. These bones are often healthy tissues, which can be ground to form autologous bone powder, which can be used to repair the operation cavity after the operation. Therefore, it is of great significance to collect healthy bone meal during surgery. [0003] When grinding bone with an electric drill, it is generally required to use flowing normal saline to continuously flush the operation cavity, and use a suction device to continuously attract the polished bone debris, tissue fragments and other components, so as to keep the operation field clean and facilitate the operator to identify th...
