People are after producing dermatosis, often be the mode that adopts manually scratching, extruding, manual squeezing is because antibacterial on hand, and the size of finger, cause handling unclean, very easily cause infection, and stayed nonvolatil cicatrix, cause other problem, skin site of pathological change volume ratio sometimes is bigger, after puncturing, only expose a bit, it can't be pushed out, caused idle work.
The utility model content
The purpose of this utility model is to overcome the problems that existing scalpel brings when carrying out large volume morbidity skin treatments, designed a kind of new type medical equipment, this medical apparatus and instruments simple in structure, after skin is punctured, utilize the arc-shaped structure of its end face, increased the contact area with the skin disease locus, the morbidity skin of large volume can have been tripped out, the affected part has been handled clean.
The purpose of this utility model is achieved through the following technical solutions: a kind of new type medical equipment, 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, described joint pin is connected with cutter head away from an end of support column, and cutter head is tabular sheet metal, and sheet metal is arc surface away from the end face of an end of union joint, the smooth connection of sidewall of arc surface and sheet metal, the radian of its arc surface is 2rad to 3rad.
Further, the radian of described arc surface is 2.5rad.
Further, the angle between the axis of the axis of described cutter head and joint pin is 10 ° to 15 °.
Further, the angle between the axis of the axis of described cutter head and joint pin is 12.5 °.
Further, described support column forms groove away from the end face indent of joint pin, and groove is circular groove, and the degree of depth of circular groove is 1.5mm.
Further, the outer wall indent of described support column forms several annular grooves, and the distance between the adjacent annular groove is 13mm to 15mm.
Further, the distance between the adjacent annular groove is 14mm in the described annular groove.
Further, the outer wall indent of described support column forms platform, and the degree of depth of platform is 2.5mm.
Further, the quantity of described platform is two, and is symmetricly set on the support column along the axis of support column.
In sum, the beneficial effects of the utility model are: this medical apparatus and instruments simple in structure, after skin is punctured, utilize the arc-shaped structure of its end face, increased the contact area with the skin disease locus, the morbidity skin of large volume can have been tripped out, the affected part has been handled clean.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Labelling and corresponding parts title in the accompanying drawing: 1-circular groove; 2-platform; 3-support column; 4-annular groove; 5-joint pin; 6-cutter head.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of new type medical equipment, the support column 3 that comprises inner hollow and an end opening, described support column 3 inside are provided with joint pin 5, and joint pin 5 one ends are arranged on the outside of support column 3, and described joint pin 5 is connected with cutter head 6 away from an end of support column 3, cutter head 6 is tabular sheet metal, and sheet metal is arc surface away from the end face of an end of union joint, and smooth connection of sidewall of arc surface and sheet metal, the radian of its arc surface is 2rad to 3rad; The best radian of arc surface is 2.5rad.In mathematics and physics, radian is the linear module at angle, and two rays penetrate to circumference from the center of circle, shape in an angle with angle over against one section arc.When this section arc length just in time equals radius of a circle, article two, the radian of the angle of ray is 1, be set to arc surface by the sheet metal termination, arcwall face has a progressively process of contact in the time of can making to large volume morbidity skin treatment, final realization comprehensive engagement, increased contact area, can the skin treatment of large volume is clean, avoided causing the phenomenon of idle work.
