A kind of anti-skidding nail anvil of hysteroscope staplerTechnical field
The present invention relates to medical instruments field, more particularly to a kind of anti-skidding nail anvil of hysteroscope stapler.
Background technology
Minimally Invasive Surgery occupies the critical role in surgical operation at present, wherein, it is surgical operation that focus is carried out into excisionAn important part, general method is that the operating theater instruments of surgery has a long axle or shaft-like knot at presentStructure, axle or bar are probeed into focus under the cooperation of endoscope, and by lesion resection.
The one kind of hysteroscope stapler as operating theater instruments, it is the equipment of the replacement manual suture medically used；StaplerOperation principle be that stapler is clamped in lesions position, cut off, while excision by focus using titanium follow closely to organize intoRow detachment is coincide, similar to stapler.
But anti-skidding design is not done on the head of the hysteroscope stapler nail anvil table wall of prior art, mainly restricted traditional deviceIt is small that the nail anvil head of tool accommodates power, can not play ideal effect head design is anti-skidding.
The content of the invention
Goal of the invention：In view of the shortcomings of the prior art with defect, the present invention provide a kind of operation is simple, oozing of blood risk is low,The anti-skidding nail anvil of hysteroscope stapler that sustainable productivity is high, cost is low.
Technical scheme：A kind of anti-skidding nail anvil of hysteroscope stapler of the present invention, it is characterised in that：Including nail anvil plate and anvil head；Described anvil head is located at the head of nail anvil plate and is fixedly connected with nail anvil plate, and anvil head is provided with several spherical anti-skid bulges；It is describedAnti-skid bulge surface be provided with anti-skid structure layer.
Wherein, described nail anvil plate is metallic sintered products.
Wherein, described nail anvil plate material is 05Cr17Ni4Cu4Nb stainless steels.
Wherein, described nail anvil plate is made of powder metallurgy injection moulding.
Wherein, described anti-skid bulge is ball bumps.
Wherein, described anti-skid structure layer is rubber layer or plastic layer.
Beneficial effect：Compared with prior art, the present invention has following remarkable advantage：The anti-skidding nail anvil of the present invention reduces auxiliaryInstrument carries out tissue clamping, improves operation simple type；Prevent the nail that tissue flowing is brought not to be molded, reduce oozing of blood risk；MouldInjection moulding, sustainable productivity is high, and cost is superior.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
1 is anti-skid bulge in figure.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to technical scheme.
A kind of anti-skidding nail anvil of hysteroscope stapler of the present invention, including nail anvil plate and anvil head；Anvil head is located at the head of nail anvil plateAnd be fixedly connected with nail anvil plate, anvil head is provided with several spherical anti-skid bulges 1；The surface of anti-skid bulge 1 is provided with anti-skid structure layer, preventsSliding projection 1 is ball bumps, and anti-skid structure layer is rubber layer or plastic layer；Nail anvil plate is metallic sintered products, nail anvil plate materialFor 05Cr17Ni4Cu4Nb stainless steels, nail anvil plate is made of powder metallurgy injection moulding.
Anti-skidding design, the nail of mainly restricted traditional instruments are not done in the head of the hysteroscope stapler nail anvil table wall of prior artIt is small that anvil head accommodates power, can not play ideal effect head design is anti-skidding.It is easy for problems with occur in this case：1、Apparatus clamp thick tissue when, formed squeeze after organize easily occur slipping, it is necessary to by other apparatuses to tissue carry out it is spacing,Side tissue is possible to can be swollen by folder；2nd, such as clamp without auxiliary, flowed when being organized in suture, stapler goes out nail and easily occurredTilt, cause nail not to be molded when serious, tissue sutures power deficiency and oozing of blood occurs after dicing, has hidden danger.
The anti-skidding nail anvil of the present invention reduces aid and carries out tissue clamping, improves operation simple type；Prevent tissue fluxion strapThe nail come is not molded, and reduces oozing of blood risk；Mould is injection moulded, and sustainable productivity is high, and cost is superior.
The technical solution adopted by the present invention is the anti-skidding design in nail anvil head, compared to the anti-skidding work of clamping of the existing product to tissueWith becoming apparent from.The nail anvil plate is metallic sintered products, and its head is provided with spherical anti-skid structure anti-skid bulge 1, contrast machining orSheet metal component, production powder metallurgy injection moulding MIM techniques have following advantage：1st, the intensity deficiency of sheet metal component, itself does not just haveIt is necessary design method, and the part after powder metallurgical technique injection moulding, it is enough can to ensure that part has by heat treatmentIntensity, so in head design, this anti-skidding can play ideal effect；2nd, machining and sheet metal process are processed into anti-slip tankThis is huge, and metallic sintered products are realized more simple due to the advantage of its mould.
