The utility model adopts the technical proposal that:

the utility model provides a mammary prosthesis syringe, including cylinder, syringe needle and with cylinder complex piston push rod, the one end of cylinder is equipped with annotates the liquid head, the syringe needle includes outer needle and interior needle, the afterbody of outer needle with annotate the liquid head and connect, the syringe needle of outer needle is arc, the syringe needle orientation of outer needle the cylinder sets up, the syringe needle of outer needle is equipped with the confession the opening that the interior needle passed, be equipped with the confession on the piston push rod the through-hole that the interior needle passed.

The injection needle is punctured into a breast prosthesis of a human body, the inner needle of the injection needle is punctured rapidly, after the puncture is successful, the inner needle is taken out, medical workers inject injection liquid (normal saline or silica gel) in the needle cylinder into the outer needle through the liquid injection head by pushing the piston push rod, the injection liquid is injected into the breast prosthesis through the opening on the needle head of the outer needle, and then the concave position of the breast prosthesis is repaired. The breast prosthesis injector can rapidly inject normal saline or silica gel into the breast prosthesis, and has the advantages of convenient and rapid injection and high injection efficiency.

Further, a sealing ring is arranged between the outer needle and the liquid injection head.

The sealing ring is arranged between the outer needle and the liquid injection head, so that the injection liquid in the outer needle can be isolated from the outside, and the outside air is prevented from entering the human body.

Furthermore, one end of the piston push rod, which is far away from the injection needle, is provided with a block matched with the through hole.

Plug up the interior needle in with the through-hole through the sprue, avoid medical personnel interior needle to wear out the through-hole when using and cause the injury to medical personnel, when needs take out interior needle, take off the sprue, then take out interior needle, convenient operation is swift.

Furthermore, a syringe seat is arranged at one end of the syringe far away from the injection needle.

When the medical staff is used, the fingers are fixed on the syringe seat, so that the operation is convenient, and the working efficiency is improved.

The utility model has the advantages that:

1. the normal saline or the silica gel can be quickly injected into the breast prosthesis, the injection is convenient and quick, and the injection efficiency is high;

2. a sealing ring is arranged between the outer needle and the liquid injection head, so that the injection liquid in the outer needle can be isolated from the outside, and the outside air is prevented from entering the human body;

3. the inner needle in the through hole is blocked by the blocking block, so that the inner needle is prevented from penetrating out of the through hole to hurt medical staff when the medical staff use, when the inner needle needs to be taken out, the blocking block is taken down, then the inner needle is taken out, and the operation is convenient and rapid;

4. when the medical staff is used, the fingers are fixed on the syringe seat, so that the operation is convenient, and the working efficiency is improved.
