Description

Bone marrow collection device

Technical field

The utility model relates to the field of medical instrument technology, in particular to a kind of Bone marrow collection device.

Background technique

Clinically when encountering the patient, especially sufferers of osteoporosis face of a large amount of bone defects or nonunion, doctor is most The also most intractable of headache is no bone, and common practice is taken from body bone collection at present, and popular saying is to tear Dong Qiang benefit open Xi Qiang, the ilium or fibula for being derived from body carry out free or pedicle graft, the disadvantage is that bone amount is limited and causes donor site function Obstacle.Also allograph bone can be used or artificial bone is filled, but will appear rejection and bone largely absorbs in this way, it is past It is not so good as people's will toward effect.How to obtain bone tissue and is capable of the factor puzzlement clinician of promoting bone growing and knitting.? In clinical practice we have found that when carrying out expansion marrow, a large amount of marrow and bone slag can be generated, these during surgery all by It is discarded, however the also active constituent of a large amount of bone tissues and bone in these discarded tissues, such as osteoblast, osteoclast, Mesenchymal stem cell and active factors and protein.We must also should get up these tissue collectings, again sharp It with effectively being treated, both solves the problems, such as bone amount, also solves the problems, such as to promote growth.

However, existing Bone marrow collection mainly leans on empty needle negative-pressure ward ilium at present, to obtain marrow.It can be made after extraction At the pain of extracting region.It takes ilium to rob Peter to pay Paul, causes the pain in belt area.Rejection is had using allograph bone and bone is inhaled Receipts problem, and the marrow for expanding marrow outflow in bone surgery, there is no special collection method.

Utility model content

The purpose of this utility model is：It proposes a kind of Bone marrow collection device, can very easily collect and expand in marrow operation The largely discarded marrow generated, then separated, so that the function according to different component targetedly treats different type Defect and damage.

Technical solution adopted by the utility model to solve its technical problems is：

Bone marrow collection device, including collecting pipe and Guan Gai cover in the pipe and are inserted with suction tube, suction tube and negative respectively Pressure pipe；The negative tube is connect by a connecting tube with a vacuum extractor；The suction tube is attracted by a diversion pipe and one Pillow connection；The middle part of the collecting pipe is equipped with a filter screen, and it is through described that the tube body of the suction tube passes through the filter screen The bottom of collecting pipe.

Further, the nozzle base of the suction tube and negative tube is located at the top of the filter screen.

Further, the top of the suction tube is equipped with a sealing-plug, and when not in use, which is sealed by sealing-plug.

Further, the collecting pipe is connected through a screw thread with the pipe lid, and sealing ring is equipped in the pipe lid.

Further, the aperture of the filter screen is less than 1mm, can filter marrow slag.

The utility model has the beneficial effects that：Discarded marrow can be collected using the present apparatus during operation, then carry out richness Collection and separation, then it is used for the treatment of sufferers of osteoporosis face, to compensate for bone defect, strainer can be directly separated out greatly Block bone slag, improves the effect of separation.In addition, the present apparatus can also be used to collect cell.The present apparatus has compact structure, at low cost It is honest and clean and easy to use, the features such as having a wide range of application.

Detailed description of the invention

Fig. 1 is the utility model structure diagram.

In figure：1- collecting pipe, 2- pipe lid, 3- suction tube, 4- suction tube, 5- negative tube, 6- diversion pipe, 7- attract syringe needle, 8- connecting tube, 9- vacuum extractor, 10- sealing-plug, 11- filter screen.

Specific embodiment

Below in conjunction with attached drawing, the utility model is described further.

The specific implementation structure of the utility model as shown in Figure 1, include collecting pipe 1, pipe lid 2, suction tube 3, suction tube 4, Negative tube 5 attracts syringe needle 7 and vacuum extractor 9.

Wherein, collecting pipe 1 and pipe lid 2 are connected through a screw thread, and sealing ring is arranged in pipe lid 2, for reinforcing sealing effect Fruit.

Suction tube 3, suction tube 4 and negative tube 5 are plugged in the top of pipe lid 2 respectively, and suction tube 3 passes through a diversion pipe 6 It is connect with syringe needle 7 is attracted, negative tube 5 is connect by connecting tube 8 with vacuum extractor 9.

It is equipped with a sealing-plug 10 at the top of suction tube 4, when collecting marrow, sealing-plug 10 clogs suction tube 4, keeps its close Envelope.

It is equipped with a filter screen 11 at the middle part of collecting pipe 1, and the aperture of filter screen is less than 1mm, for isolating bulk Bone slag.

The bottom of suction tube 3 and negative tube 5 is located at the top of filter screen 11, and it is straight that the tube body of suction tube 4 passes through filter screen 11 Up to the bottom of collecting pipe 1.

Vacuum extractor 9 is the commonly used equipment in hospital, and no longer it is described in detail in this programme.

The working principle of the utility model is：Start vacuum extractor 9, the discarded marrow that syringe needle 7 will be attracted to be placed on outflow In, under the action of atmospheric pressure, marrow is flowed into collecting pipe 1 by diversion pipe 6, and wherein filter screen 11 is by the bone slag in marrow Filtering is above strainer, and marrow flows into the bottom of collecting pipe 1, after the completion of collecting, can take out collecting pipe 1 and be put into centrifuge Different tissues is inside isolated, when need to use, the sealing-plug 10 at 4 top of suction tube is opened, is extracted from the top of suction tube 4 Marrow in collecting pipe 1.

The advantages of basic principles and main features and this programme of this programme have been shown and described above.The technology of the industry Personnel are it should be appreciated that this programme is not restricted to the described embodiments, and the above embodiments and description only describe this The principle of scheme, under the premise of not departing from this programme spirit and scope, this programme be will also have various changes and improvements, these changes Change and improvement is both fallen within the scope of claimed this programme.This programme be claimed range by appended claims and its Equivalent thereof.
