Description

Novel tongue mucosa cutter

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a novel tongue mucosa cutter.

Background

The free mucosa is a repair material which is commonly used in urethral forming treatment, and the free mucosa which is applied to clinic comprises bladder mucosa, oral mucosa, tongue mucosa, colon mucosa and the like. At present, the mucous membrane of the bladder is used less frequently due to complications and other factors, and the mucous membrane of the buccal cavity is accepted by vast urologists as a classic substitute for reconstructing the urethra. The tongue mucous membrane reconstruction urethra has obvious curative effect on treating urethral stricture in recent years, and a new repair material is added for treating urethral stricture. Oral mucosa was first proposed as a urethral replacement by Humby in 1941 and applied to the buccal mucosa in the hypospadia, and this formula was widely applied to urethral diseases since 1992. The theoretical advantages of the oral mucosa used as a urethra repair substitute include thicker epithelial cell layer and dense tissue characteristics than other grafts, stronger anti-infection and anti-wound capability of the new urethra than other grafts, convenient material availability, simple operation, easy mucosa stripping, elasticity, slight shrinkage and strong anti-infection capability.

At present, the oral mucosa is accepted by most urology surgeons as a substitute for reconstructing the urethra, and the urethral shaping by the patch method and the effect of treating the bulbar urethral stricture are ideal. Due to the limited source of buccal mucosa and the relatively deep location, it is difficult to use as a graft for urethral reconstruction of complex, lengthy urethral strictures. The mucous membranes on the lateral surface and the bottom surface of the tongue have no special function, are completely the same as the mucous membranes on the cheek in structure, and can be used as the material-taking parts. The tongue mucosa can generally provide a graft with a length of 6-15 cm and a width of 1.5-2.5 cm. In addition, the tongue mucous membrane has good tissue characteristics, thick epithelium, rich elastic fiber, thin mucous membrane inherent layer, easy vascularization after transplantation and easy survival. For doctors with abundant experience, the tongue mucosa is easy to cut, but for urologists without special training, the cutting difficulty is high, the cut tongue mucosa has certain defects, adverse effects can be caused on subsequent urethroplasty operations, and the complication incidence rate is increased. If the tongue mucosa resection device can be invented, the resection of the tongue mucosa is easy, most urologists can easily master the tongue mucosa urethra repair and reconstruction technology, and more patients can be easily diagnosed and treated.
