Bone powder collecting and cleaning device

Abstract

A bone powder collecting and cleaning device comprises a bone powder collecting tank and a bone powder separator. The bone powder collecting tank comprises a tank body. The tank body has one opening and furthermore the opening is in threaded connection with a cover. The cover is provided with a first plugging pipe and a second plugging pipe. The first plugging pipe is in plugging connection with aconnecting flexible pipe. The connecting flexible pipe is in insertion connection with a hard attracting head. A second connecting pipe is connected with a negative pressure flexible pipe. The negative pressure flexible pipe is provided with an adapter. The adapter is connected with a medical attracting device. The bone powder separator comprises an upper circular pipe and a lower bracket. The upper flexible pipe is hollow and is provided with a channel. The channel is internally provided with a filtering film along the end surface of the upper flexible pipe. A lower bracket is provided witha snapping channel. The bone powder collecting tank forms a negative pressure in the tank body through a medical attractor for attracting the bone powder into the tank body along with flushing liquid.The waste liquid which is collected in the tank body is poured into the bone powder separator. A filtering film in the upper circular pipe is utilized for separating the waste liquid from the bone powder, thereby realizing collection and separation of the bone powder, and greatly improving bone powder collecting, separating and taking-out speed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone meal collection and cleaning device. Background technique [0002] Bone defects caused by various reasons are very common in humans. The reconstruction materials include autologous bone, allograft bone and artificial materials, and autologous bone is still the preferred material. Reconstruction of the bone wall of the air-space-containing cavity, including the mastoid, involves reconstruction of the air cells with cortical bone fragments, covering of cortical bone with bone particles to form the inner layer of the reconstructed bone wall, and bone meal to form the outer layer of the reconstructed bone wall. [0003] At present, there is a lack of special equipment for bone powder collection and cleaning in China. The operator carefully grinds the bone during the operation, and cannot wash the bone grinding surface with water. After the bone grinding, only a small a...

Problems solved by technology

[0004] In the above technical solution, the bone powder in the waste liquid can be collected by connecting the ear bone powder collector to the suction tube of the negative pressure suction device through the waste liquid suction joint and the waste liquid discharge joint, but the bone powder is deposited on the bone powder collector during use. Internally, it is difficult for nurses to clean the bone powder, which affects the effect of the operation and the recovery progress of the patient. There are improvements in the existing technology
