Description
Technical field
The utility model relates to a kind of technical field of medical instruments, especially a kind of cutter for the preoperative cleaning skin of surgery.
Background technology
Before carrying out operation, guarantee that operation completes smoothly for preventing hair infected wound, medical worker needs first to be rejected by the hair at corrective surgery position clean with preparation skin knife.The preparation skin knife of current use, its similar shaver, dynamics, angle are not easy to grasp, and easily scratch skin, and the place such as oxter, groin not easily scrape totally, thus the process of impact operation.Meanwhile, hand also may be caused when medical personnel use injured.
Utility model content
For the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of rational in infrastructure, the disposable preparation skin knife that easy to operate, safe surgery is preoperative.
The technical solution of the utility model is: disposable preparation skin knife, comprise the supporting plate, blade, the pressing plate that to be fixed on by fixed screw on handle of a knife, wherein, before, during and after described pressing plate divides three, one end of forward and backward and middle hinged, another termination of forward and backward is provided with nut, arranges adjustment stud between two nuts, and described adjustment stud is arranged in the fairlead of sheet termination in pressing plate.
The screw thread at described adjustment stud two ends is oppositely arranged.
The corner of described blade is all set to the circular arc without sword.
Described supporting plate both sides length direction is provided with floating guide ribs.
The utility model structure is simple, uses safe and reliable.Blade is hidden between supporting plate and pressing plate, and during use, rotate and regulate stud, pressing plate is circled round, and blade exposes, and after using, pressing plate outward turning blade is hidden, by medical waste treatment.

Fig. 3 is supporting plate cross sectional representation of the present utility model;
In figure: 1-handle of a knife, 2-guide ribs, 3-blade, 4-pressing plate, 5-nut, 6-supporting plate, 7-fixed screw, 8-fairlead, 9-regulates stud.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1,2,3, the disposable preparation skin knife that the utility model provides, comprise the supporting plate 6, blade 3, the pressing plate 4 that to be fixed on by fixed screw 7 on handle of a knife 1, wherein, before, during and after described pressing plate 4 points three, one end of forward and backward and middle hinged, another termination of forward and backward is provided with nut 5, arrange between two nuts 5 and regulate stud 9, described adjustment stud 9 is arranged in the fairlead 8 of sheet termination in pressing plate 4.Before using, forward and backward of pressing plate 4 is in most outward turning position, makes blade 3 be hidden between supporting plate 6 and pressing plate 4, during use, rotate and regulate stud 9, make forward and backward convolution of pressing plate 4, blade 4 exposes, nut 5 and regulate stud 9 effect under forward and backward of fixation clip 4.
Preferably, the screw thread at stud 9 two ends is regulated oppositely to arrange.This structure, when rotating adjustment stud 9, can make forward and backward synchronous outward turning or the convolution of pressing plate 4.
Preferably, the corner of blade 3 is all set to the circular arc without sword.When preserved skin groin or underarm areas, encounter surrounding skin when blade two ends and also can not cause additional injuries, decrease the misery of patient.
Preferably, supporting plate 6 both sides length direction is provided with floating guide ribs 2.When preserved skin operates, guide ribs 2 prior to blade 3 and skin contact, guide ribs 2 with have relative high friction between skin, skin is convenient to blade 3 and is carried out scraping after being unfolded, improve the quality of preserved skin.
The utility model structure is simple, uses safe and reliable.Before using, forward and backward of pressing plate is in most outward turning position, hides blade between supporting plate and pressing plate, ensure that the safety of medical personnel when tool for transmitting.During use, rotate and regulate stud, make forward and backward convolution of pressing plate, blade reveals, and the corner of blade is all set to the circular arc without sword, can not cause additional injuries, decrease the misery of patient.After using, rotate and regulate stud, make forward and backward outward turning of pressing plate, hide blade, by medical waste treatment.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
