Problems solved by technology

[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

Embodiment 1

[0016] see Figure 1-2 In this embodiment, it includes a plasma injector 1, a thrombin injector 2, and an air injector 3, and the plasma injector 1, the thrombin injector 2, and the air injector 3 are connected and fixed into one body through a fixing device;

[0017] The fixing device comprises a first positioning piece 4 and a second positioning piece 5 arranged parallel to the first positioning piece 4, the two ends of the first positioning piece 4 are respectively vertically fixed with guide shafts 30, and the guide shafts The end of 30 passes through the second positioning piece 5 which is slidingly fitted with the gap, and the two ends of the second positioning piece 5 are respectively provided with a first U-shaped groove 6 for the passage of the plasma syringe 1 and a gap for the thrombin syringe 2. Through the second U-shaped groove 7, one side of the first U-shaped groove 6 is provided with a first limiting groove 61 parallel to it, and the first flange part 11 of th...

Embodiment 2

[0022] 1. First pump the processed PRP plasma into the plasma syringe 1, the plasma syringe 1 in this embodiment is a 5-10ml medical syringe;

[0023] 2. Prepare the thrombin injection solution according to the ratio of 500u thrombin powder mixed with 1ml normal saline, and pump the prepared thrombin injection solution into the thrombin syringe 2, the thrombin syringe 2 in this embodiment is a 1ml medical syringe;

[0024] 3. Drag the height distance between the first positioning piece 4 and the second positioning piece 5 to a suitable position, insert the first flange part 11 of the plasma syringe 1 into the first U-shaped groove 6 and the first limiting groove 61, insert the first push rod end piece 12 of the plasma syringe 1 into the first positioning slot 41; insert the second flange part 11 of the thrombin syringe 2 into the second U-shaped groove 7 and the second limit Between the slots 71, insert the second push rod end piece 22 of the thrombin syringe 2 into the second...

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...
