[0002] Breast augmentation surgery is a method of placing prosthetic materials suitable for the patient's chest type on the chest through surgery. There are many types of incisions, which can be selected according to the patient's specific basic conditions.

[0003] After searching, the patent application number CN201420269783.9 discloses a special pusher for breast augmentation implants. When in use, the surgeon opens the cap, places the prosthesis into the main cavity of the injector, places the front end of the main cavity into the surgical incision, passes through the subcutaneous tissue channel, and reaches the prosthesis placement site. Fix the device with one hand and rotate the threaded injection handle with the other hand to drive the rubber piston forward slowly, slowly injecting the prosthesis into the target placement site. After completion, remove the injector and then adjust the position of the prosthesis.

[0004] However, in actual use, the above patent has the following defects: after use, the user cannot easily clean the prosthesis remaining on the inner wall of the syringe. Therefore, we propose a prosthesis inserter for breast plastic surgery. Utility Model Content

[0007] Furthermore, a piston is movably connected inside the injection cylinder, a piston rod is fixedly connected to the left side of the piston, and the left end of the piston rod passes through the injection cylinder and the retaining ring in sequence and extends to the outside of the retaining ring and is fixedly connected to a push plate.

[0008] Furthermore, the fixing mechanism includes a connecting groove, a connecting block, a limiting groove, a through groove, a column, a threaded plate, a sliding plate, a screw, a handle and a limiting block. The top and bottom of the side of the retaining ring close to the injection barrel are both provided with connecting grooves, and the internal movably clamped connection of the connecting groove is connected with a connecting block.

[0009] Furthermore, the connecting block is fixedly connected to the injection cylinder, and a limiting groove is provided on the side of the two connecting blocks away from each other, and a through groove is provided at the top and bottom of the retaining ring at the position corresponding to the limiting groove.

[0010] Furthermore, the top and bottom of the retaining ring are fixedly connected to two columns, the sides of the two columns away from the retaining ring are fixedly connected to the same threaded plate, and the sides between the two columns and close to the retaining ring are slidably connected through a sliding plate.

[0011] Furthermore, the sliding plate is in movable contact with the retaining ring, a bearing is fixedly connected to the center of the side of the sliding plate away from the retaining ring, and a screw is rotatably connected to the side of the bearing away from the retaining ring.

[0012] Furthermore, the end of the screw away from the bearing passes through the threaded plate and extends to the outside of the threaded plate and is fixedly connected to a handle. The screw and the threaded plate are threadedly connected. The side of the sliding plate close to the retaining ring is fixedly connected to a limiting block. The side of the limiting block away from the sliding plate sequentially passes through the through groove and the limiting groove and extends to the inside of the limiting groove. The limiting block and the limiting groove are movably engaged.
