Description

Disposable intraoperative bone meal collector

technical field

The utility model relates to a disposable bone powder collector in operation.

Background technique

During ear or dental surgery, it is often necessary to use a vacuum suction device to remove or aspirate surgical waste. Because the operation waste liquid often contains a large amount of blood clots and bone debris powder, not only it is easy to cause the suction device to be blocked, but also the bone debris is crushed and the waste liquid is discarded, resulting in waste. Autologous bone powder is needed to repair surrounding bone defects in operations such as dental implants. In open mastoid surgery such as chronic suppurative otitis media, mastoid packing after thorough treatment of the lesion is beneficial to reduce postoperative complications. Among them, autologous mastoid cortical bone powder is used by surgeons because it is convenient to obtain materials and overcomes the rejection problem of artificial materials. During the restoration and filling treatment, the autologous mastoid cortical bone was used as the material, and the mastoid cortical bone was ground with a large cutting drill before opening the mastoid, and the bone powder was collected for future use. However, bone debris and bone powder are often mixed in the surgical waste liquid, which is difficult to collect, and the surgical waste liquid may also be mixed with soft tissues, which is not conducive to the reuse of bone powder. Therefore, it is necessary to provide a new type of intraoperative bone powder collector.

Utility model content

The purpose of the utility model is to provide a disposable bone powder collector in the operation. The bone powder collector of the utility model is disposable. After the operation, the collecting chamber can be cut off to take out the bone powder.

The disposable intraoperative bone meal collector provided by the utility model includes a disposable transparent collection chamber; a water inlet and a water outlet are arranged on the collection chamber, and the water inlet is connected with a water inlet pipe. The water outlet is connected with the drain pipe;

An upper filter net and a lower filter net are arranged in the cavity of the collection chamber; the upper filter net is connected to the water inlet end of the collection chamber and communicated with the water inlet; the lower filter net is connected to the water inlet The water outlet end of the collection chamber is connected to the water outlet.

In the above-mentioned disposable intraoperative bone meal collector, the mesh size of the upper filter screen can be 15-20, so as to pass through the bone powder with a smaller particle diameter, and components such as soft tissue or granulation that may be mixed in the operation cavity can be filtered out ;

The mesh size of the lower filter screen may be 180-200, and through the lower filter screen, bone chips in the surgical waste liquid are filtered and retained in the collection cavity, and the surgical waste liquid is discharged.

In the above-mentioned disposable intraoperative bone powder collector, the collection cavity is a cylindrical cavity.

In the above-mentioned disposable intraoperative bone powder collector, near the water inlet end, a pipeline is connected to the water inlet pipe, and the opening end of the branch pipeline is sealed by a rubber cap; the branch pipeline is used as a "spare" The water inlet pipe is used, when the water inlet pipe is blocked, it is used as a temporary water inlet pipe, and is connected with a negative pressure suction device, and the water inlet end is sealed with the rubber cap.

In the above-mentioned disposable intraoperative bone meal collector, the free end of the drainage pipe is provided with an interface connected with the negative pressure suction device, which is convenient for connecting with the negative pressure suction device.

The collection chamber, the water inlet pipe and the drain pipe can be made of soft transparent plastic such as medical polyvinyl chloride, so that the filtered bone powder can be collected by cutting off the collection chamber.

The utility model disposable intraoperative bone powder collector has the following advantages:

The utility model realizes the collection of intraoperative bone debris by arranging two filter screens with different apertures in the collecting cavity. And the structure is simple, the cost is low, and it can be prepared from polyvinyl chloride. When using the disposable intraoperative bone powder collector of the utility model to collect bone powder, the operation is convenient and fast, and finally the bone powder obtained by filtering can be collected by cutting the collection cavity.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings, but the utility model is not limited to the following embodiments.

As shown in Figure 1, the disposable intraoperative bone powder collector provided by the utility model includes a disposable transparent collection chamber 1, which is cylindrical and made of polyvinyl chloride, so it can be cut to take out the collection chamber 1. bone meal. One end of the collection chamber 1 is provided with a water inlet 2, and the other end is provided with a water outlet 3. The water inlet 2 is connected with the water inlet pipe 4, and the operation waste liquid enters the collection chamber 1 from here, and the water outlet 3 is connected with the drain pipe. 5 is connected, and the filtered surgical waste liquid is discharged from the collection chamber 1 from here. An upper filter screen 6 and a lower filter screen 7 are arranged in the cavity of the collection chamber 1, wherein the upper filter screen 6 is connected to the water inlet end of the collection chamber 1 and communicated with the water inlet 2; the lower filter screen 7 is connected to the collection chamber 1's water outlet end, and communicate with water outlet 3. In the utility model, the mesh number of the upper filter screen 6 is 16, the purpose is to pass through the bone powder with a smaller particle diameter, and the components such as soft tissues that may be mixed in the operation cavity can be filtered out; the mesh number of the lower filter screen 7 is 200 , through the lower filter screen 7, the bone debris in the surgical waste liquid is filtered and retained in the collection cavity, while the surgical waste liquid is discharged.

In the utility model disposable intraoperative bone meal collector, in order to cope with the situation that the water inlet pipe 4 is blocked, a branch pipeline 8 is connected to the water inlet pipe 4 near the water inlet end, and the opening end of the branch pipeline 8 passes through a rubber cap 9 It is sealed and used as a "spare" water inlet pipe, which acts as a temporary water inlet pipe. Branch pipeline 8 also can be made by medical polyvinyl chloride. When the water inlet pipe 4 is blocked and cannot be repaired, the rubber cap 9 can be removed from the spare branch pipe 8 to seal the entrance of the water inlet pipe 4; and the spare branch pipe 8 is connected with the negative pressure suction device head to continue working.

In the utility model disposable intraoperative bone meal collector, in order to be conveniently connected with the negative pressure suction device, an interface (not shown) that can be connected with the negative pressure suction device is set at the free end of the 5 drainage pipes.

When using the disposable intraoperative bone powder collector of the utility model, the drainage pipe is connected with the negative pressure suction device used in the operation, and the water inlet pipe joint is placed in the operation cavity to attract the operation waste liquid. At this time, the liquid in the waste liquid Composition will be sucked away by negative pressure suction device, and bone meal will stay between upper filter screen 6 and lower filter screen 7 two filter screens. After the required bone meal is collected, the collector is separated from the negative pressure suction tube, and the part between the two filter screens of the collector is cut off to obtain the required bone meal.
