Description

The depth-adjustment sphere touches the skin dermatotome

Technical field

This utility model relates to a kind of medical surgical instrument, and specifically a kind of depth-adjustment sphere in incision of skin when operation that is applicable to touches the skin dermatotome.

Background technology

At present, when surgical operation is cut skin, cut skin with scalpel always, this scalpel is made of blade, handle of a knife, when skin was cut in operation, the patient held handle of a knife armrest method skill and directly cuts skin, its weak point: the one, and notch depth is difficult to adjust, the depth is wayward, crosses and can injure other tissue deeply; The 2nd, touch surface armrest fingers and palms and hold, hold the cutter hands and often produce shake, cause the edge of a knife for straight line, occur askewly partially, influence suture quality.

Summary of the invention

The purpose of this utility model is to provide a kind of depth-adjustment and controls notch depth easily, avoids touching the skin dermatotome because of the askew partially depth-adjustment sphere of otch appears in hands shake.

For reaching above purpose, the technical scheme that this utility model adopted is: this depth-adjustment sphere touches the skin dermatotome, by the cylinder handle of a knife, blade, the location spheroid constitutes, it is characterized in that cylinder handle of a knife and location spheroid are connected to one, in location spheroid and cylinder handle of a knife, establish the flat hole of connection, blade inserts from the flat hole of location spheroid front end, and be screwed, the blade both sides are equipped with blade, establish sliding tray along blade centerline, screw inserts in the sliding tray of blade perpendicular to the axial hole in flat hole along the location spheroid, when nose part stretch out the length of location spheroid selected after, tighten screw, blade is fixed, establish axial screw at the center of cylinder handle of a knife, axially establishing adjusting screw(rod) in the screw, on the cylinder handle of a knife, establish the end on observation seam with the corresponding position of blade tail end, on the edge of end on observation seam, be provided with scale, by the adjustment of adjusting screw(rod), the length that stretch out at the adjustable blade tip, and in the end on observation seam, observe the scale that cutter stretches out.This utility model is also implemented by following measure: the width in the flat hole of insertion of blade is consistent with the width of blade, establish the rotation chuck in the end of adjusting screw(rod), the clamp port that rotates chuck is clipped in the tail end of blade, and the rotation bulb that rotates chuck is stuck in the cave of adjusting screw(rod) end; Cylinder handle of a knife, blade, location spheroid are stainless steel material and make.When using this utility model, according to the operative site skin thickness, determine the point of a knife exposed length by rotating screw bolt, tighten screw then, can determine that blade cuts the skin degree of depth, in operation, also can finely tune at any time by the rotation adjusting screw(rod), because the location spheroid is a sphere, be convenient to slide, can not produce askew partially because of the hands shake.

The beneficial effects of the utility model are: compare with cutting the skin scalpel at present, cutting-in is convenient to adjust fixing, and tangent line is difficult for askew partially, and the edge of a knife two lips are easy to sew up symmetrically.

The specific embodiment

Make this utility model with reference to accompanying drawing 1,2,3,4.This depth-adjustment sphere touches the skin dermatotome, by cylinder handle of a knife 1, blade 2, location spheroid 3 constitutes, cylinder handle of a knife 1 is connected to one with location spheroid 3, in location spheroid 3 and cylinder handle of a knife 1, establish the flat hole 5 of connection, blade 2 inserts from the flat hole 5 of location spheroid 3 front ends, and it is fixing with screw 4, blade 2 both sides are equipped with blade, establish sliding tray 6 along blade 2 centrages, screw 4 inserts in the sliding tray 6 of blade 2 along the axial hole perpendicular to flat hole 5 of location spheroid 3, establish axial screw 9 at the center of cylinder handle of a knife 1, axially establishing adjusting screw(rod) 7 in the screw 9, on cylinder handle of a knife 1, establishing end on observation seam 8, on the edge of end on observation seam 8, be provided with scale 10 with the corresponding position of blade 2 tail ends, by the adjustment of adjusting screw(rod) 7, the length that stretch out at adjustable blade 2 tips.The width in the flat hole 5 of the insertion of blade 2 is consistent with the width of blade 2, establishes in the end of adjusting screw(rod) 7 and rotates chuck 11, and the clamp port that rotates chuck 11 is clipped in the tail end of blade 2, and the rotation bulb that rotates chuck 11 is stuck in the cave of adjusting screw(rod) 7 ends; Cylinder handle of a knife 1, blade 2, location spheroid 3 are stainless steel material and make.
