Intraoral skin anastomat and using method thereof

Abstract

The invention relates to an intraoral skin anastomat which comprises a sheath shell, a pushing block, clamping pincers and an anastomosis nail. The sheath shell is a hollow cuboid strip, the upper endof the sheath shell is open, a cylindrical shaft is arranged at the end opening, and a spring catch is arranged on the inner center line. The pushing block is a cuboid strip, an isosceles triangle groove is formed in the lower end of the pushing block, a rectangular through hole-spring hole is formed in the middle section of the pushing block, and a spring is arranged in the spring hole; the pushing block is arranged in the sheath shell, and the spring catch is arranged in the spring hole. The clamping pincers achieve the opening and closing functions of the pincers with a sheath shell cylindrical shaft as the axis, pincer mouths are two sections of arcs, a groove with the arc section is formed in the inner side center line, a spring piece is arranged between pincer arms, the pincer armsare arranged in the isosceles triangle groove, and the tail ends of the pincer arms make contact with the waist line of the isosceles triangle groove. The two ends of the anastomosis nail are providedwith metal wires with the same curvature as the clamping forceps, and the outer diameter is the same as the inner diameter of the clamping forceps groove. The skin anastomat is suitable for anastomosis of wounds in the oral cavity and also suitable for anastomosis of narrow and deep wounds.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intraoral skin stapler and a method for using the same. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers , Lung cutting stapler, etc. Compared with traditional manual suturing, instrumental suturing has the following advantages: 1. Simple and convenient operation, saving operation time; 2. One-time use, avoiding cross infection; 3. Using titanium nails or stainless steel nails (skin stapler) to suture tightly and elastically Moderate; 4. It has few side effects and effecti...

Problems solved by technology

[0003] The current skin stapler is not suitable for oral wound anastomosis in terms of structure and size, and it is difficult to suture oral wounds, so a skin stapler suitable for oral cavity is needed
