Abstract

The utility model relates to an incision model capable of continuously adjusting different depths for an animal experiment. The characteristics are as follows: a third thin plate and a fourth thin plate are parallel to and equal to a first base and a second base, and are fixed with the first base and the second base through screws; the ends of the third thin plate, the fourth thin plate, the first base and the second base are embedded into a hinge and are screwed up through screws; the screws at both sides are respectively embedded into a first arc-shaped scribing sheet and a second arc-shaped scribing sheet of which the middle parts are provided grooves; a gap is arranged between the third thin plate, the fourth thin plate and the first base, the second base, a first thin plate and a second thin plate are respectively located on the third thin plate and the fourth thin plate and are fixed through two screws; and a blade is arranged in the gap among the first thin plate, the second thin plate, the third thin plate, the fourth thin plate, the first base and the second base and is vertical to the bases. The third thin plate and the fourth thin plate are opened and closed, the blade can be used for cutting a required depth, so that the incision model has active effect on wound healing and regeneration and scar healing and is an effective incision model for the animal experiment.

Description

The continuous adjustable different depth otch model of a kind of zoopery

Technical field

This utility model relates in the zoopery by the model that gos deep into shallow continuous cutting.

Background technology

In zoopery; A lot of specialties are especially at the animal model that need make some line style different depth otch aspect the orthopedic cicatrization; The superficial injury of skin histology is mainly accomplished the wound regenerative healing through hypertrophy, migration and the flap coverage of basal cell; Yet can cause tangible cicatrization after injuring lamina reticularis; The degree of depth that dermal tissue is damaged is directly proportional with the degree of scar hyperplasia, can what kind of degree of depth dermal tissue is damaged to actually just not form cicatrix? People such as Dong Ting are at " critical depth that cicatrix takes place behind the skin injury: accurately measure progressive degree of depth corium damage among the volunteer " (Dunkin CS J, Pleat JM; Gillespie PH; Tyler MPH, Roberts AHN, people such as McGrouther DA. are at Scarring Occurs at a Critical Depth of Skin In jury:Precise Measurement in a Graduated Dermal Scratch in Human Volunteers.Plast Reconstr Surg.2007; 119 (6): introduced a kind of otch model 1722-1732.); Yet the degree of depth of this kind model is fixed, and can't regulate the degree of depth of cutting, and the skin thickness at each position of human body is different.The place is the thinnest with eyelid, is about 0.3mm; Vola portion skin is the thickest, and this application of model scope just is restricted.For extremely, cut a same line style otch ratio of the degree of depth and be easier to realize so far, want in zoopery adjustablely continuously, cutting different depth otch is difficulty relatively just.Therefore developing a kind of continuous otch model from shallow to deep just seems necessary.

Summary of the invention

In view of above-mentioned, the purpose of this utility model is to provide a kind of zoopery continuous adjustable different depth otch model.This model can be adjustable continuously, the otch of cutting different depth, thus objectively adapt to the various physiological changies in the wound healing process.

The purpose of this utility model is achieved in that

The continuous adjustable different depth otch model of a kind of zoopery is by blade, first thin plate, second thin plate, the 3rd thin plate, the 4th thin plate, first base, second base, and the first arc scribing, the second arc scribing and hinge are formed.The 3rd thin plate equates with second base is parallel with the 4th thin plate and first base, and is fastening with screw; Its end embeds hinge, screws down; In the middle of embedding respectively, the both sides screw has in the first arc scribing and the second arc scribing of groove; Gapped between the 3rd thin plate and the 4th thin plate and first base and second base; First thin plate, second thin plate are located in respectively on the 3rd thin plate and the 4th thin plate; Fix by two screws; Blade places between the gap of first thin plate, second thin plate, the 3rd thin plate, the 4th thin plate, first base, second base, and perpendicular to base.

The advantage of this utility model and the beneficial effect of generation are:

This utility model utilizes blade holder existing and that generally use, and movable the 3rd thin plate and the 4th thin plate can arrive at arbitrary scale in the scribing, and utilization is colluded strand law and can accurately be calculated the degree of depth of cutting.Blade can cut the required degree of depth, and it does not show scar hyperplasia and produce positive role for the healing of wound, is the effective zoopery otch of tool model.

The specific embodiment

As shown in Figure 1; The continuous adjustable different depth otch model of a kind of zoopery; Be to form by handle of a knife 1, first thin plate 2, second thin plate 3, the 3rd thin plate 6, the 4th thin plate 7,

first base

9,10, the first arc scribings 4 of second base, the second arc scribing 5 and hinge 8.The 3rd thin plate 6 and the 4th thin plate 7 and first base 9 and second base 10 are rectangle and parallel, occupy a plane in twos respectively, use screw fastening therebetween; The end of the 3rd thin plate 6, the 4th thin plate 7, first base 9, second base 10 embeds hinge 8, screws down.What have groove in the middle of the both sides screw embeds respectively is in the first arc scribing 4 and the second arc scribing 5 of radius with the 3rd thin plate 6 length, in the arc scribing scale is arranged.The 3rd thin plate 6 and the 4th thin plate 7 and

first base

9 and 10 of second bases are gapped; First thin plate 2, second thin plate 3 are located in respectively on the 3rd thin plate 6 and the 4th thin plate 7; Fix by two screws; The handle of a knife 1 that contains No. 11 blades places between the gap of first thin plate 2, second thin plate 3, the 3rd thin plate 6, the 4th thin plate 7, first base 9 and second base 10; When the 3rd thin plate 6 and the 4th thin plate 7 slide when changing angles, unscrew the back through the screw on first thin plate 2, second thin plate 3 and regulate the angle of handle of a knife 1 and make it all the time the plane formed perpendicular to first base 9 and second base 10.

Movable the 3rd thin plate 6 and the 4th thin plate 7, the three thin plates 6 and the 4th thin plate 7 slide at the groove of the first arc scribing 4 and the second arc scribing 5, can arrive at arbitrary scale in the scribing, and utilization is colluded strand law and can accurately be calculated the degree of depth of cutting.Blade can be through the required degree of depth of gap cutting knife of first thin plate 2, second thin plate 3, the 3rd thin plate 6, the 4th thin plate 7, first base 9, second base 10.
