Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a punching assembly and a punching device. The punching device comprises a fixing assembly used for fixing a wound covering and a punching assembly used for punching the wound covering; the punching assembly comprises a knife rest, an adjusting plate and a distance locking piece; the knife rest comprises a fixed arm used for installing and fixing a puncture piece and a movable arm used for installing and moving the puncture piece; one end of the adjusting plate is connected with the fixed arm; andthe other end of the adjusting plate is connected with the movable arm through a distance locking piece. Due to the fact that the distance locking piece can fix the movable arm to different positionsof the adjusting plate, the distance between the fixed puncture piece and the movable puncture piece can be adjusted, and the distance between the fixed puncture piece and the movable puncture piece can be adjusted according to needs. A user can hold the punching assembly by hand to punch a wound covering, and the wound covering with evenly distributed holes is obtained. According to the punchingdevice, punching operation can be completed by one person, safety and convenience are achieved, the hole distance is uniform, and the appearance effect of postoperative wound coverings is good.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a punching assembly and a punching device. Background technique [0002] Various wound coverings are often used in wound repair surgery, including autologous skin, allogeneic skin, heterogeneous skin, artificial dermal scaffolds, and various special dressings. Due to their biological or material characteristics, these wound coverings are not permeable, which often causes blood and fluid accumulation in the human tissue under the covering and infection. In severe cases, the covering will dissolve and fall off as a whole, resulting in failure of wound repair or even infection. Diffusion aggravates the condition. In clinical use, it is necessary to punch holes in various wound coverings to facilitate the drainage of blood and fluid under the coverings. The usual method is that 2-3 surgical personnel hold or clamp the wound coverings, and then use a scalpel b...
