Description

Strutting arrangement suitable for breast arc incision

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a strutting arrangement suitable for breast arc incision.

Background

When a tumor cutting operation is performed on a breast, in order to ensure the attractiveness of the whole breast after the breast is restored, a doctor can cut an arc-shaped incision along the periphery of the breast during the operation, and then the breast is stretched along the incision by adopting an instrument, so that the doctor can precisely cut a tumor in the breast.

As shown in FIG. 10, when the doctor operates on the breast, the doctor cuts the breast through the half-moon-shaped arc incision of FIG. 10, which causes the left and right side walls of the breast incision to be large and small after the incision is finished; if need expose for propping the tissue of both sides, what adopt at present all stretches into in the middle of the incision through a plurality of independent drag hooks, take off the incision from a plurality of directions again, this in-process is owing to adopt a plurality of drag hooks, consequently need a plurality of doctors to cooperate just can strut the tissue that exposes breast inside with this incision is better, it causes among the operation process on the one hand doctor to operate inconveniently, on the other hand doctor's working strength is big, and the interference of human factor is big, doctor at the pulling the drag hook is stiff in the hand, perhaps be when attention is not concentrated, the incision that appears originally being taken off reduces easily, influence the doctor's operation, and then it is low to cause the operation success rate.

However, because the breast tissues under the arc-shaped incision are distributed according to the sector, the radian of one side of the stretched breast tissues is small, and the corresponding breast tissues are few; the breast tissue on the other side has large radian and more corresponding tissues, the width of two sides of the existing spreader is consistent, and the breast tissue with small radian can block the spreader from being inserted into the breast tissue, so that the spreader can not fully expose the tissues in the incision; although there are spreaders with different sizes in the market at present, if the spreader is selected according to the breast tissue at the side with small radian, the spreader is smaller at the side with large radian, so that the tissue at the side cannot be spread completely; however, if the spreader with the corresponding size is adopted according to the breast tissue on one side with large radian, the spreader is too large to be placed and used, so the existing spreaders in the market at present are very inconvenient to use.
