Abstract
The utility model relates to an improved medical electric knife head, which is characterized in that a knife head 1 is a thin stainless steel needle, and the utility model can particularly use a medical syringe needle head 2 which is connected with a nozzle 4 of a handle 5 through a connector 3. The thin needle-shaped stainless steel electric knife head can cause energy to be concentrated to a needle tip on the end. When the utility model conducts an operation of cutting tissues and conducting haemostasis, the utility model has the advantages of quick energy transmission, rapid cutting of the tissues, and reduced cauterization and coking quantity. The utility model is suitable for surgical operations of burn, shaping, etc.
Description
This utility model relates to a kind of improvement of electro-medical cutter head.
The electro-medical cutter head is that surgical operation cuts and organizes, the hemostatic medical apparatus and instruments, as one of critical piece of electric knife, electric coagulating knife, comprises handle and cutter head, and the cutter head that uses generally is flat at present, and knife face is big and thick.There is following defective in the cutter head of this shape: the energy that is delivered to cutter head disperses; be difficult for concentrating; when surgical cut is organized; electric knife head is grown with organizing time of contact; so that tissue injury's face is big, also darker, the coking tissue is many during cutting; amount of smoke is big, and some normal activity tissues have in various degree burn, inactivation on the wound surface of cutting back.Damage influence is in various degree especially arranged in burn plastic operation, skin transplantation.Simultaneously extensive tiny petechia on to wound surface also exists cutter head contact bleeding point to organize time point long, that burn also bigger during hemostasis, and the certain influence that skin transplantation is survived is especially to having considerable influence such as operating effects such as burn, shapings.
This utility model purpose is to provide a kind of electro-medical cutter head of novelty, to overcome the above-mentioned defective that existing electric knife head exists.
Technical solutions of the utility model are: adopt thin stainless pin to replace existing flat and thick cutter head.Because fine acicular cutter head volume, surface area are less, energy easily focuses on the needle point of plagiocephaly end, undergo surgery and cut and organize, have when stopping blooding that energy delivery is rapid, the time is short, cut and organize very easily rapidly agilely, and the coking amount is little and reduce amount of smoke when burning, more be applicable to some trainings, as operating requirements such as burn, shapings.
Be described further below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a kind of example structure sketch map of this utility model electric knife head.
Fig. 2 is the another kind of example structure sketch map of this utility model electric knife head.
By Fig. 1, this electro-medical cutter head comprises handle 5 and cutter head 1, cutter head 1 is thin stainless pin, for keeping certain degree of hardness, soft bullet phenomenon can not occur when contacting and shank, needle point are contacted effectively with tissue tight with tissue in burnt scar of excision and hemostasis, preferably adopt the hollow thin stainless pin, this pin result of use is better.Fig. 2 is this utility model another embodiment:, be connected by the nozzle 4 of adapter 3 with handle 5 front ends as cutter head with the commonly used injection needle 2 of hospital, adapter is preferably cone, and there is screw thread 6 on the surface.Can be used with the entry needle of different model like this.The cutter head forward part can bend to certain angle, and it is convenient, laborsaving more to feel nature when hemostasis operation.
