Description
Technical field
This utility model relates to a kind of Medical surgical utensil.
Background technology
Surgical instrument refers to the medical apparatus and instruments used in clinical operation, except routine operation apparatus, also has the apparatus of some trainings, representative is scalpel, at present, high frequency electric knife adopts high-speed steel base material and ceramic base material, this material is frangible easily crisp during use, cause service life not long, the scalpel of ceramic base material is charged, under band frequency state, impact is had on people, and affect thermal conduction effect, thus affect operation and carry out, increase the injury risk again that patient cures period, in addition, ceramic base material operationally its temperature controls inaccuracy, and thermal control compensate is not enough, blade is made to mend temperature, rise again not, do not reach the result of use of expection, be not suitable with propagation and employment.
How to provide one can accurately control blade temperature, applied range, safety and easily surgical instrument become and need the urgent problem solved.
Summary of the invention
For solving the problem, this utility model provide a kind of can wide, durable, the safe and reliable surgical instrument of precise control of temperature, the scope of application.
This utility model provides a kind of surgical instrument, and this surgical instrument is disposed object position to operation and cut and process, and described surgical instrument comprises:
Handle part, has the accessory held for operator;
Disposal portion, has the disposal parts of cutting, tweezer, hemostasis or ligation;
Linking part, described accessory is with to dispose parts dismantled and assembled or link regularly;
Described handle part and disposal portion are overall structure, and described handle part or periphery, disposal portion are sprayed and had ceramic coating, and described ceramic coating and handle part or disposal portion form composite structure.
Described ceramic coating bearing temperature scope is-1200 DEG C-860 DEG C, described ceramic coating adopts spraying to be injected in handle part or disposal portion outer surface, described handle part or periphery, disposal portion are covered completely by ceramic coating, the thickness of described ceramic coating is within the scope of 1cm-0.01 millimeter, and the density of ceramic coating reaches 90%-99%.Described surgical instrument is heat setting scalpel, cryoprobe or operating scissors.
After adopting this utility model surgical instrument, its beneficial effect is:
Handle part or periphery, disposal portion are sprayed and are had ceramic coating, described ceramic coating bearing temperature scope is-1200 DEG C-860 DEG C, its surface, disposal portion is not glued, operationally, ceramic coating is coated on utensil, its temperature can be good at conducting to utensil outer surface, this ceramic coating can play anti-stick, the effect of hemostasis or ligation, overcome the weak point of other operating theater instruments, when temperature rises to 1 boundary's point, noxious substance can not be given out, more safe and reliable, when cryosurgery, can transition temperature well, in addition, it is strong that the feature of ceramic coating has corrosion resistance, cold-and-heat resistent alternation performance will obviously be better than common paint coatings, anti-wear performance also strengthens greatly, greatly can extend the service life of surgical instrument.
This surgical instrument can to without base material or there is base material to protect again; can use under heat setting or condensed environment; during traditional electric knife about 1000 degree; the function that can reach; by scribbling the surgical instrument of ceramic coating, it just can reach this function within 800 degree, makes conductive performance better; be coated with electricity or coagulate without electric heating or all utensil utilizations in condensation field, making applied range.
Accompanying drawing explanation
Fig. 1 is the structural representation of the heat setting scalpel of the surgical instrument of this utility model embodiment.
Detailed description of the invention
According to Fig. 1, be described the surgical instrument of an embodiment of the present utility model and heat setting scalpel, for heat setting scalpel, this surgical instrument is disposed object position to operation and is cut and process, and described surgical instrument comprises:
Handle part, have the accessory held for operator, heat setting scalpel has blade holder 1;
Disposal portion, have the disposal parts of cutting, tweezer, hemostasis or ligation, heat setting scalpel has knife blade 2, and knife blade is in flake, and its side, front end is provided with blade 3;
Linking part, described accessory is with to dispose parts dismantled and assembled or link regularly, and described knife blade 2 plugs together with blade holder 1 and is fixedly connected with;
Described handle part and disposal portion are overall structure, and described handle part or periphery, disposal portion are sprayed and had ceramic coating 4, and described ceramic coating and handle part or disposal portion form composite structure, and the peripheral injection of described knife blade has ceramic coating 4.
Described ceramic coating 4 adopts spraying to be injected in handle part or disposal portion outer surface, and the thickness of wherein said ceramic coating is within the scope of 1-0.01 millimeter.
Described ceramic coating bearing temperature scope is-1200 DEG C-860 DEG C.
The processing technology of its ceramic coating is:
Process at utensil base and the harmonious face of pottery, ceramic material spray and utensil is made to can be good at merging, different according to utensil shape, in surface-treated degree slightly difference, liquid slurry is injected in thermal spraying gun, sprayed on surgical instrument substrate surface by thermal spraying gun and form sprayed coating, ceramic coating material comprises oxide, the composition such as silicide or nitride, described knife blade outside is covered by ceramic coating, the thickness of wherein said ceramic coating is within the scope of 1-0.01 millimeter, the density of ceramic coating reaches 90%-99%, spray post-drying and form thin shape, transition material is provided with between surgical instrument and ceramic coating, it is overlapping with transition material that it forms thin shape ceramic coating, add that ceramic coating does not glue, anti-wear performance, knife blade entirety is used better, more convenient, ceramic coating bearing temperature is high, its temperature-controllable, adjustable, temperature is regulated by switch key, surgical instrument not easily bonds after using, be convenient to cleaning.
Under essential condition, also can on original surgical instrument basis repeatedly spraying ceramic coat, increase ceramic protective layer.
