Abstract

The utility model relates to a disposable scalpel used for medical surgery. Which comprises a knife head and a knife holder which are connected into a whole by compression molding, wherein, the knife head adopts a metal blade; the knife holder is made of non-poisonous plastics. The disposable scalpel after wrapped is processed with the cobalt 60 radiation sterilization, and unsealed before operations for use. Therefore, the preoperative sterilization and the installation procedure can be omitted; the iatrogenic cross infection can be avoided; the preparation time of operations is shortened, and the rescue work can be timely. The disposable scalpel can be extensively suitable to the occasions of the surgical operations, such as the clinical, the outpatient service and the salvage at scene.

Description

Disposable scalpel

This utility model belongs to medical apparatus and instruments.

The scalpel that common surgery is used generally is made up of stainless handle of a knife and blade, through sterilization treatment, assembles before the art.During sterilization treatment, then with soaking before the on-the-spot art of medicinal liquid, it is inconvenient that the medical worker feels for handle of a knife vapor sterilization, blade.Even also found blade generation rusty stain phenomenon in the first-aid kit.In addition, also can not possess because of condition under some situation, operate lack of standardizationly, sterilization does not thoroughly stay the hidden danger of cross infection.Medical plastic is used widely at present, and it provides condition for the integrated manufacturing of scalpel.And, make disposable use possess realistic possibility because cost reduces.

The purpose of this utility model is to provide a kind of incorporate disposable surgical cutter, thereby has overcome above-mentioned existing in prior technology some shortcomings.

The disposable surgical cutter that this utility model relates to structurally is made up of handle of a knife and cutter head two parts.The blade of cutter head part and handle of a knife end are connected with suitable key or the pin in insert pocket or hole by one.Blade perhaps is fixed on the amesiality position in the middle of being fixed on by compression moulding.The latter's fixed form adopts the hot pressing riveting, also can adopt the mode of sliding card connection of the prior art.Intensity can improve by increase safe edge in the handle of a knife end in blade back place.Handle of a knife adopts avirulent plastics, and as the PVC material manufacture, blade adopts ready-made knife blade.According to the specification and the use habit of present surgical blade, handle of a knife can be made big young waiter in a wineshop or an inn's kind, big handle of a knife and 21 ^#Blade cooperates, little handle of a knife and 10 ^#, 10 ^#, 12 ^#, 15 ^#Blade cooperates.This all-in-one-piece disposable surgical cutter, the shape of its cutter head changes with blade shapes is different.Scalpel is packed after cleaning, dried, makes irradiation sterilization with cobalt 60 then and handles, and single treatment can reach the safe and sanitary storage life in 2 years.

From now on, blade also can substitute with the good hard nonpoisonous plastic material of structural stability, thereby produce complete plastifying disposable surgical cutter.

The disposable surgical cutter has following advantage

1, because the disposable use of scalpel can avoid iatrogenic operation (cutter) to infect.

2, the disposable use of scalpel is guaranteed to its quality, also helps improving the operation quality.

3, save disinfecting time, saved disinfectant solution, got rid of the probability that blade gets rusty.

4, help performing the operation preparation and rescue.The disposable surgical cutter is sealed off and can be performed the operation, and need not sterilize temporarily, has striven for valuable rescue time.

Further specify below in conjunction with embodiment and accompanying drawing

Fig. 1 is the structural representation of disposable surgical cutter

Fig. 2 be the disposable surgical cutter embodiment two

Fig. 3 be the disposable surgical cutter embodiment three

Fig. 4 is the another kind of version of adapted blade

With reference to Fig. 1, the disposable surgical cutter is made up of cutter head 1, handle of a knife 2.Blade 5 is existing 21 ^#Knife blade, plastic compression are fixed on the centre of handle of a knife end, and dotted line is represented is coupling part between blade 5 and the handle of a knife 2.Handle of a knife 2 is a flat pattern, and the handle of a knife stricture of vagina 3 on the handle of a knife is to be used for increasing frictional force between finger and handle of a knife.Point of a knife, the edge of a knife are continuously and expose, and it is multiple that the back part of blade 5 is that the end of handle of a knife is buried.

The embodiment that Fig. 2 represents, the blade 5 of cutter head part are positioned on the side of deflection handle of a knife end, among the figure blade 5 below be the support face, in order to increase area with proof strength.Be blade 5 above, it is fixed on the handle of a knife 2 by connecting key 4 usefulness hot pressing riveting forms.Also can overlap the lastblock plastic spacer more above.

In the present embodiment, press fixingly, and guide groove is set in the side of connecting key 4, just can carry out with sliding card installation method with existing knife blade handle of a knife if do not adopt.Finished product installs packing again before dispatching from the factory.

What Fig. 3 represented is the basic structure situation of overall plasticization disposable surgical cutter.

The adapted blade that Fig. 4 represents, blade are provided with 1-2 the fixedly hole 6 of usefulness.
