A kind of multifunctional skin flap retractor in breast surgery

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and especially relates to a multifunctional flap retractor in breast surgery. The flap retractor includes a number one clamping plate; a number two clamping plate is installed in the number one clamping plate, and the lower surface of the number one clamping plate is in spinning connection with a rotary knob througha screw thread; a vertical cylinder is integrally formed on the upper surface of the number two clamping plate; the upper part of the vertical cylinder is provided with a number one cross rod; a vertical rod, a column block and a sleeve block are successively connected between the vertical cylinder and the number one cross rod; and a number two cross rod penetrates one side of the number one cross rod. Through the stable effects of the sliding connection between the vertical cylinder and the vertical rod and between the number two cross rod and the number one cross rod, space adjustment can be performed on the positions of operation components of flap traction; through the utilization of the relative moving between the number two clamping plate and the number one clamping plate and the spinning operation of the rotary knob, installation and dismantling can be conveniently achieved, and the operation time of medical personnel can be decreased; and through the symmetric sector arrangement of hooks on the two sides and the spaced clamping and fixing effects of clamping blocks in interval blocks, the effects of flap traction can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates 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 the pedicled flap, but the pedicle does not need to be cut after the local flap or island flap is transferred. In breast surgery, it is often necessary to perform ...

Problems solved by technology

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 the pedicled flap, but the pedicle does not need to be cut after the local flap or island flap is transferred. In breast surgery, it is often necessary to perform extensive flaps or flaps on the subcutaneous, chest muscle or rib surface. Tissue separation, due to the large potential separation surface, dense tissue, and rich blood vessels, the operation process is difficult, time-consuming, and causes a lot of bleeding. Therefore, good traction and exposure of the flap or tissue will help the operation go smoothly , the flap retractor for breast surgery in the prior art is inconvenient to adjust during use, and has poor flexibility; at the same time, the installation and disassembly effect is not good, which easily leads to prolonged operation time for medical staff and poor practicability; and The effect of skin flap stretching needs to be improved, which reduces the efficiency of breast surgery to a certain extent
