Problems solved by technology

[0002] In clinical work, the slow healing speed of chronic wounds (such as pressure sores) is mostly due to the existence of necrotic tissue, so it is necessary to remove necrotic tissue (ie, slough) to achieve debridement to facilitate wound healing. In the process, it is necessary to use tweezers and scissors together to remove the rotten tissue, but for the deep necrotic tissue, it is difficult for tweezers to grasp the irregular and slippery necrotic tissue, and even small pieces of necrotic tissue cut off by scissors are easy to fall into the Deep, resulting in incomplete debridement, troublesome operation, low treatment efficiency, prolonging the wound healing time of patients, increasing the pain and economic burden of patients

Abstract

The invention discloses a debridement knife for carrion. The debridement knife comprises a joint pipe, a connecting pipe and a driving mechanism,the connector pipe is detachably and spirally connected with the connecting pipe, the top end of the connector pipe is connected with a hemispherical cleaning cover, and an opening is formed in the upper side face of the hemispherical cleaning cover. A cleaning cutter assembly is rotationally arranged on the inner side of the connecting pipe and comprises a cleaning cutter head and a center rotating shaft connected to the cleaning cutter head. The negative pressure connecting pipe is arranged on the connecting pipe, and the negative pressure connecting pipe is communicated with hospital negative pressure, so that necrotic tissues are directly sucked through the opening in the hemispherical cleaning cover and extend into the hemispherical cleaning cover from the opening when the necrotic tissues are cleaned;compared with traditional cleaning through tweezers and scissors matching pieces, the operation is convenient and efficient, the pain of a patient is relieved, and wound healing is facilitated.

Description

technical field [0001] The invention relates to the technical field of carrion meat debridement knife, in particular to a carrion meat debridement knife. Background technique [0002] In clinical work, the slow healing speed of chronic wounds (such as pressure sores) is mostly due to the existence of necrotic tissue, so it is necessary to remove necrotic tissue (ie, slough) to achieve debridement to facilitate wound healing. In the process, it is necessary to use tweezers and scissors together to remove the rotten tissue, but for the deep necrotic tissue, it is difficult for tweezers to grasp the irregular and slippery necrotic tissue, and even small pieces of necrotic tissue cut off by scissors are easy to fall into the In the deep part, it causes incomplete debridement, troublesome operation, low treatment efficiency, prolongs the wound healing time of patients, and increases the pain and economic burden of patients. Contents of the invention [0003] The purpose of the...
