Description

Technical Field

[0001] The utility model belongs to the technical field of skin stapling devices, in particular to a skin stapling device with replaceable forceps heads. Background Art

[0002] Skin stapler, medically known as "disposable skin stapler" or "skin stapler", "disposable skin stapler", "skin stapler", is a device used in medicine to replace manual suturing. Its working principle is similar to that of a stapler, mainly using titanium staples to staple tissues.

[0003] When using a skin stapler to suture a skin wound, the clamp head of the skin stapler needs to contact the surface of the skin wound and may be contaminated by blood, tissue fluid, etc. These contaminants are difficult to completely remove through conventional methods. In order to prevent patient infection, the skin stapler is a disposable device. The problem with the above technology is that the clamp body of the skin stapler does not contact the skin and is not contaminated. The disposable skin stapler causes the clamp body to be discarded and wasted. Utility Model Content
