Description
Technical field
This utility model provides a kind of roll shaft skin fetching knife, belongs to field of surgical, the operating theater instruments that especially a kind of burns unit uses.
Background technology
In skin graft operation, need to cut from body skin or heterodermic graft in damaged skin place with roll shaft skin fetching knife, need to help when using the roll shaft skin fetching knife bark fetching help skin-tightening, often owing to exerting oneself the inhomogeneous skin graft became uneven that takes off that makes, the trend of blade is passed through manual control during operation, be easy to depart from the direction of anticipation, cause the skin graft irregularity got, and during bark fetching, need to measure skin graft length by ruler, operation is trouble comparatively, and medical matters efficient is lower.
Chinese patent CN201220097370.8 discloses a kind of novel roll shaft skin fetching knife, it comprises: blade, pressure roller, handle of a knife, and the blade both sides are fixed with slide block, and the slide block below is provided with framework, framework is provided with the guide rail that cooperates with slide block, and wherein the outside of a guide rail is provided with scale.During use, framework is fixed on the bark fetching place, the pulling handle of a knife makes blade and pressure roller move forward along guide rail can realize bark fetching, and it is simple in structure, and is easy to operate, has significant practicality.The deficiency of its existence is, can not determine the lateral length at bark fetching position, and blade angle is non-adjustable, causes easily bark fetching thicker.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: the roll shaft skin fetching knife that a kind of accurate control bark fetching process is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of roll shaft skin fetching knife, the place ahead that is included in blade is provided with by the fixing pressure roller of support, blade one side is provided with handle of a knife, it is characterized in that: the blade both sides are fixed with slide block, the slide block below is provided with framework, and framework is provided with the guide rail that cooperates with slide block, and wherein the outside of a guide rail is provided with the first rule, blade is fixed on the support by blade holder, and blade holder arranges the second rule.
The first rule can be used for marking reference length, and the second rule can be used for marking the width of bark fetching, avoids bark fetching not of uniform size, causes area inadequate, and the perhaps excessive waste of area realizes accurately control bark fetching.
Wherein preferred version is:
Described blade holder arranges the angular adjustment knob, and the angular adjustment knob is divided into 8 grades, 0.2 °-0.5 ° of every grade of angle.Use at present Humby knife to be provided with 4 scales and select, regulate scale, span is large, and is thicker, meticulous not.Arrange after 8 grades, can realize accurate THICKNESS CONTROL.
Described blade holder arranges the paraffin oil adding trough.In can inject a small amount of paraffin oil, before normal doctor's bark fetching, generally smear blade and skin donor site with medical paraffin oil first, keeps moistening, reduce friction, easier bark fetching, but in the operation, the easy drying such as auxiliary and bark fetching time of assistant is long need be added paraffin oil again.Add sulculus (identical with blade face), interiorly inject a small amount of paraffin oil, keep a period of time, be more conducive to pipetting of skin graft.
Compared with prior art, the beneficial effect that this roll shaft skin fetching knife has is: be fixed with slide block by the blade both sides, the slide block below is provided with framework, framework is provided with the guide rail that cooperates with slide block, wherein the outside of a guide rail is provided with the first rule, blade is fixed on the support by blade holder, blade holder arranges the second rule, the first rule can be used for marking reference length, the second rule can be used for marking the width of bark fetching, avoids bark fetching not of uniform size, causes the bark fetching area inadequate, the perhaps excessive waste of area realizes accurately control typing bark fetching.By global optimization, this utility model is easy and simple to handle, and target is accurately located, and has both kept the integrity (spready hide) of skin, does not waste again the skin source.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Wherein, 1, framework 2, pressure roller 3, support 4, handle of a knife 5, angular adjustment knob 6, the second rule 7, blade holder 8, blade 9, slide block 10, guide rail 11, the first rule.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
Embodiment 1:
As shown in Figure 1, be provided with the pressure roller 2 of fixing by support 3 in the place ahead of blade 8, blade 8 one sides are provided with handle of a knife 4, blade 8 both sides are fixed with slide block 9, slide block 9 belows are provided with framework 1, and framework 1 is provided with the guide rail 10 that cooperates with slide block 9, and wherein the outside of a guide rail 10 is provided with the first rule 11, blade 8 is fixed on the support 3 by blade holder 7, and blade holder 7 arranges the second rule 6.
Blade holder 7 arranges angular adjustment knob 5, and angular adjustment knob 5 is divided into 8 grades, 0.2 °-0.5 ° of every grade of angle.Can realize accurate THICKNESS CONTROL.
Blade holder 7 arranges the paraffin oil adding trough.
Operation principle or use procedure:
During use, framework 1 is fixed on the bark fetching place, pulling handle of a knife 4 makes blade 8 and pressure roller 2 move forward along guide rail 10 and can realize bark fetching, because guide rail 10 1 sides are provided with scale, can show the length of bark fetching, need not to re-use rule and measures.The first rule 11 can be used for marking reference length, and the second rule 6 can be used for marking the width of bark fetching, avoids bark fetching not of uniform size, causes area inadequate, and the perhaps excessive waste of area realizes accurate configuration control bark fetching.
