Abstract
The utility model relates to a medical dressing tweezers, including last tweezers arm (1), pick up something with tweezers arm (2), first joint portion (3) and second joint portion (4) down, on pick up something with tweezers the arm and pick up something with tweezers the arm under with and set up relatively to pick up something with tweezers on, and be provided with guide block (11) on the arm, be provided with first guide block (21) and second guide block (22) that are parallel to each other on picking up something with tweezers the arm under, spacing distance between first guide block and the second guide block can hold the thickness of guide block, a binding site converges the part in what the arm was picked up something with tweezers under with to last tweezers arm jointly, the 2nd binding site also lies in between first joint portion and first guide block and the second guide block between first joint portion and last guide block, the second joint portion is the elasticity split ring of " omega " form for the appearance. The utility model has the advantages of fatigue strength is high, picking up something with tweezers the arm from top to bottom, to open and shut the number of times many.
Description
Technical field
This utility model patent relates to a kind of medical apparatus and instruments, especially a kind of disposable medical dressing tweezer.
Background technology
Medical dressing tweezer is the tweezers for surgery clamping dressing, the medical tweezers of existing surgical operation generally for and prevent cross infection accident, often adopt disposable plastic tweezer, as shown in Figure 2, Chinese patent ZL201520158780.2 relates to a kind of integrated-type medical tweezers, it comprises tweezer arm 100, lower tweezer arm 200 and two basic change portion 300 and 400, wherein the second joint portion 400 is for having elastic arcuation body, play enhancing two tweezer arms 100, the effect of the rigidity of 200, but, because these tweezers are plastic tweezer, the fatigue resistance with elastic arcuation body is very low, there is opening/closing frequency in use few, the phenomenon that arcuation body easily ruptures.
Based on this, the utility model that special proposition is following.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, this utility model provides a kind of medical dressing tweezer, and its joint portion adopts new structure, not only can play the effect of the rigidity of enhancing two tweezer arms, also there is high fatigue resistance, significantly can increase the opening/closing frequency of dressing forceps.
The technical solution of the utility model is: a kind of medical dressing tweezer, comprise tweezer arm, lower tweezer arm, the first joint portion and the second joint portion, described upper tweezer arm and lower tweezer arm are oppositely arranged, upper tweezer arm is provided with guide block, lower tweezer arm is provided with the first lower guide block be parallel to each other and the second lower guide block, and the spacing distance between described first lower guide block and the second lower guide block can hold the thickness of guide block; Described first binding site converges part jointly in upper tweezer arm and lower tweezer arm, described second binding site is between the first joint portion and upper guide block, also in the first joint portion and between the first lower guide block and the second lower guide block, it is characterized in that, the elastic opening ring of to be profile be in described second joint portion " Ω " shape.
Further, the opening part of elastic opening ring is away from the first joint portion.
Further, described upper tweezer arm there is upper anti-slip tank, lower tweezer arm has lower anti-slip tank.
Further, described medical dressing tweezer is adopted made of plastic.
The beneficial effects of the utility model: owing to adding the elastic opening ring that one profile is " Ω " shape on tweezers, the fatigue resistance of the second joint portion can be strengthened, thus significantly can increase the opening/closing frequency of dressing forceps.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model medical dressing tweezer.
Fig. 2 is the structural representation of existing integrated-type medical tweezers.
In figure, the upper tweezer arm of 1-, the upper guide block of 11-, the upper tweezer head of 12-, the upper anti-slip tank of 13-, tweezer arm under 2-, 21-first lower guide block, 22-second lower guide block, tweezer head under 23-, anti-slip tank under 24-, 3-first joint portion, 4-second joint portion, the upper tweezer arm of 100-, tweezer arm under 200-, 300-first joint portion, 400-second joint portion.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model medical dressing tweezer is described further.
As shown in Figure 1, a kind of medical dressing tweezer of this utility model, comprise tweezer arm 1, lower tweezer arm 2, first joint portion 3 and the second joint portion 4, described upper tweezer arm 1 and lower tweezer arm 2 are oppositely arranged, upper tweezer arm 1 is provided with guide block 11, lower tweezer arm 2 is provided with the first lower guide block 21 and the second lower guide block 22 be parallel to each other, and the spacing distance between described first lower guide block 21 and the second lower guide block 22 can hold the thickness of guide block 11; What described first joint portion 3 was positioned at tweezer arm 1 and lower tweezer arm 2 converges part jointly, described second joint portion 4 is between the first joint portion 3 and upper guide block 11, also in the first joint portion 3 and between the first lower guide block 21 and the second lower guide block 22, described second joint portion 4 for profile be the elastic opening ring of " Ω " shape.Because the second joint portion 4 is elastic opening ring, its fatigue resistance significantly promotes, and significantly can increase the opening/closing frequency of dressing forceps.
As the elastic opening ring of the second joint portion 4, its opening is towards the direction of two tweezer heads (12,23) of dressing forceps, and also just have a talk about, its opening direction is towards the direction away from the first joint portion 3.
In order to increase frictional force when operator is affectedly bashful tweezers, upper tweezer arm 1 being manufactured with anti-slip tank 13, lower tweezer arm 2 is manufactured with lower anti-slip tank 24.
In order to save cost of manufacture, this medical dressing tweezer is adopted made of plastic.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
