People often are the modes that adopts manually scratching, extruding after producing dermatosis, and manual squeezing is because antibacterial on hand, and the size of finger, cause handling unclean, very easily cause infection, and have stayed nonvolatil cicatrix, cause other problem.
The utility model content
The purpose of this utility model is to overcome existing dermatosis people when producing and manually extrudes the problem that easy appearance infection causes staying permanent scar, designed a kind of medical surgical knife, this scalpel simple in structure, principle is easy, position by the morbidity of cutter head prick skin, utilize then under the situation of side pressure, to squeeze out the morbidity toxin, can not cause interference, guaranteed patient's safety.
The purpose of this utility model is achieved through the following technical solutions: a kind of medical surgical knife, the support column that comprises inner hollow and an end opening, described support column inside is provided with joint pin, joint pin one end is arranged on the outside of support column, the wall of joint pin contacts with the cavity of support column, and the axis of joint pin and the axis of support column are on same straight line, described joint pin is connected with cutter head away from an end of support column, and the angle between the axis of cutter head and the axis of joint pin is α, and α is 30 ° to 60 °.
Further, described α is 45 °.
Further, be sheathed with protective sleeve on the outer wall of described joint pin, an end of protective sleeve is connected with the end face of support column.
Further, the axial section of described protective sleeve is horn-like, and the end that diameter is bigger is connected with the end face of support column.
Further, the outer wall indent of described support column forms several annular grooves, and the distance between the adjacent annular groove equates.
Further, the outer wall of described support column is provided with annular knurl, and annular knurl is arranged between every adjacent annular groove.
Further, described support column is provided with handle away from an end of joint pin, and the axis of handle and the axis of support column are on same straight line, and the wall indent of handle forms platform.
Further, the quantity of described platform is two, and is symmetricly set on the handle along the axis of handle.
In sum, the beneficial effects of the utility model are: this scalpel simple in structure, and principle is easy, position by the morbidity of cutter head prick skin, utilize then under the situation of side pressure, to squeeze out the morbidity toxin, can not cause interference, guaranteed patient's safety.
