Abstract

The invention discloses a device for stuffing a human body tissue sinus tract with platelet-enriched plasma. The device comprises a plasma syringe (1), a thrombin syringe (2) and an air syringe (3), wherein the plasma syringe (1), the thrombin syringe (2) and the air syringe (3) are integrally connected and fixed through a fixing device; the fixing device comprises a first positioning piece (4) and a second positioning piece (5) parallel to the first positioning piece (4); guiding shaft rods (30) are perpendicularly fixed to two ends of the first positioning piece (4); and the ends of the guiding shaft rods (30) penetrate through the second positioning piece (5) which is in gap sliding cooperation with the guiding shaft rods (30). The device disclosed by the invention is simple in structure and convenient to use; before solidification, each corner in a lacuna can be stuffed; and after mixing is completed for about 3-5min, gel is formed, so that the lacuna in the sinus tract is stuffedto the maximum degree.

Description

technical field

[0001] The invention relates to the field related to medical care technology, in particular to a device for filling human tissue sinuses with platelet-rich plasma. Background technique

[0002] Platelet-rich plasma (platelet-rich plasma, PRP) is a concentrate of autologous platelets. Platelet-rich plasma technology is a technology that collects platelets in the blood. In addition to platelets, it is also rich in substances such as fibrinogen and growth factors.

[0003] PRP is in a liquid state after extraction. After adding thrombin, it can solidify into a gel and be used to fill sinus tracts. However, because there are potential cavities in some sinus tracts, if PRP is to be filled into every corner of the cavity, the gel It is difficult for such tissue to enter every corner of the sinus tract. Contents of the invention

[0004] The object of the present invention is to provide a device for filling sinus tracts of human tissue with platelet-rich plasma...
