Costal cartilage incision dilator for plastic surgery

Abstract

The invention discloses a costal cartilage incision dilator for plastic surgery, and belongs to the technical field of novel medical instruments. The dilator comprises four arc-shaped plates, every two adjacent arc-shaped plates are fixedly connected through an angle adjusting mechanism, dilating mechanisms are fixedly connected to the upper surfaces of the arc-shaped plates. Each dilating mechanism comprises a concave block, a dilating rod, a dilating piece, a rotating handle and a rotating rod. The concave blocks are fixedly welded to the upper surfaces of the arc-shaped plates, the inner walls of the concave blocks are connected with the dilating rods in a sliding manner, and one ends, far away from the concave blocks of the dilating rods are fixedly connected with the dilating pieces through bolts. According to the dilator, the angle adjusting mechanisms are arranged, the angle between every two adjacent arc-shaped plates can be changed, then the maximum dilating area of the dilating pieces can be changed, and therefore the dilator can be suitable for different incisions, and the practicability of the dilator is improved.

Description

technical field [0001] The invention belongs to the technical field of new medical equipment, and in particular relates to a costal cartilage incision dilator for plastic surgery. Background technique [0002] Plastic surgery is a branch of surgery, also known as plastic surgery or plastic surgery. The scope of treatment is mainly skin, muscle and bone trauma, diseases, congenital or acquired defects and deformities of tissues or organs. Treatment includes repair and repair. Create two more content. Surgical autologous tissue transplantation is the main method, and allogeneic, heterogeneous tissues or tissue substitutes can also be used to repair tissue defects or deformities caused by various reasons, so as to improve or restore physiological functions and appearance. [0003] During costal cartilage surgery, we often operate on the tissue in the incision. However, in order to avoid excessive trauma, the incision is usually not too large.

Problems solved by technology

[0003] During costal cartilage surgery, we often operate on the tissue in the incision. However, in order to avoid excessive trauma, the incision is usually not too large. However, if the incision is too small, it will bring great inconvenience to the operation. We The dilator is usually used to dilate the incision, so as to facilitate the smooth operation of the operation. However, when the existing dilator is used, its function is single, and it cannot well assist the doctor to perform the operation, and the dilator is inconvenient to fix. Easy to slip during surgery, which can greatly increase the risk of surgery
