Multifunctional flap retractor for breast surgery

Abstract

The invention discloses a multifunctional flap retractor for breast surgery. The multifunctional flap retractor comprises a supporting block, wherein a sleeve is arranged on the surface of the supporting block in a sleeved mode, a limiting frame is fixedly connected to the upper surface of the sleeve, a first gear is arranged in the limiting frame in a limiting and rotating mode, a rectangular hole is formed in the inner wall of the first gear, a rectangular rod is connected to the inner wall of the first gear in a sliding mode through the rectangular hole, a screw rod is fixedly connected tothe bottom of the rectangular rod, an internal thread sleeve is in threaded connection with the surface of the screw rod, the side face of the internal thread sleeve is fixedly connected to the innerwall of the sleeve, and the bottom of the screw rod is fixedly connected to the top of the supporting block. Through cooperative use of the structures, the problems that in an actual use process, dueto the fact that a first drag hook can cause secondary damage to the skin tissue of a patient when the first drag hook pierces into the dermis layer at the margin of the skin, postoperative wound recovery of the patient is not facilitated, and meanwhile the first drag hook is prone to loosening after piercing into the skin, so that inconvenience is brought to use are solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multifunctional skin flap retractor in breast surgery. Background technique [0002] A skin flap is formed from the skin with its blood supply and its attached subcutaneous fatty tissue. In the process of flap formation and transfer, a part must be connected with the main body (for the flap area). This connected part is called the pedicle to maintain the blood supply. After the first wound (recipient flap area), the pedicle blood supply is still supplying nutrition for the time being, and after the blood vessels in the wound surface of the flap recipient area grow into the flap and a new blood supply is established, the pedicle is cut off to complete the flap transfer Therefore, it is also called pedicled flap, but the pedicle does not need to be broken after partial flap or island flap transfer. [0003] In breast surgery, it is often necessary to perform extensive...

Problems solved by technology

[0005] However, in actual use, since the first retractor and the first retractor will cause secondary damage to the patient's skin tissue when piercing into the dermis layer of the skin edge, it is not conducive to the recovery of the patient's wound after the operation, and it is also easy to pierce into the skin simultaneously. Loose phenomenon occurs, causing inconvenience to use
