Description

Electrosurgical forceps

Technical field

The utility model relates to medical instruments fields, and in particular to a kind of Electrosurgical forceps.

Background technique

High frequency electrosurgical surgical instrument is the surgical operating instrument for electric coagulation hemostasis in surgical procedure or cutting tissue, It is clinically commonly used.Currently, high frequency electrosurgical surgical instrument is used for open surgery.High frequency electrosurgical surgical kit Include two kinds of structures of gun-type and jaw type.Wherein, the high frequency electrosurgical surgical instrument (Electrosurgical forceps) of jaw type is generally included with electrode Jaw, upper lower handle and switch.Electrosurgical forceps are connected by connector with radio-frequency generator.It is exported by radio-frequency generator High-frequency current, electric current provide high-frequency electrical energy to tissue by the electrode being separately positioned on two jaws, make between two electrodes Tissue dewatering solidification, to achieve the purpose that electric coagulation hemostasis.Since in the prior art, each jaw includes a conductive seal Surface, and need to insulate between jaw and conductive seal, cause current Electrosurgical forceps processing technology complicated, cost increase.

Utility model content

This programme technical problems to be solved are to provide a kind of Electrosurgical forceps, simplify jaw structure, reduce equipment cost.

In order to solve the above technical problems, this programme provides a kind of Electrosurgical forceps, including handle and jaw, the jaw includes First jaw and the second jaw, first jaw includes: skeleton, is fixedly connected with the handle；Insulate middleware, in institute It states and is formed after encapsulated injection molding for the first time on skeleton；Electrode is fixedly connected with the insulation middleware；Insulation crust, in the bone The outside of frame, insulation middleware and electrode by second encapsulated injection molding formation, the insulation crust envelope the skeleton, Insulate middleware and electrode；Second jaw is integrated chemical conversion type.

Preferably, the outer surface coating insulation figure layer of the skeleton.

Preferably, second jaw is made by metal injection molded moulding process.

Preferably, second jaw includes the first surface contacted with electrode, and second not contacted with electrode Surface is coated with coatings on the second surface.

Preferably, the coatings are Teflon.

Preferably, the coatings are ceramics.

Detailed description of the invention

Fig. 1 is the schematic diagram of the Electrosurgical forceps of the utility model.

Fig. 2 is the jaw schematic diagram of the Electrosurgical forceps of the utility model.

Fig. 3 is the cross-sectional view of the Electrosurgical forceps of the utility model.

Specific embodiment

The utility model is described in further detail with specific embodiment with reference to the accompanying drawing.

Referring initially to Fig. 1, open electro-surgical device 10 includes elongated handle 130 and 140, respectively has head Hold 130a, 130b and end 140a and 140b.Hereinafter " head end " refers to the closer user of open electro-surgical device 10 Hand-held one end, and " end " refers to the one end held further away from user.

Such as Fig. 1, jaw 110 is connected at the end 140b of elongated handle 140.With reference to Fig. 2 and 3, jaw 110 is wrapped Include electrode 110a, insulation crust 110d and insulation middleware 110b and skeleton 110c.Jaw 110 is encapsulated by being molded twice Mode injection molding.Specifically, encapsulated injection molding for the first time: injection molding insulation middleware 110b on skeleton 110c；Second injection molding: first Skeleton 110c, insulation middleware 110b and electrode 110a are first fixed, then insulation crust 110d is formed by encapsulated injection molding manner, absolutely Edge shell 110d firmly envelopes skeleton 110c, insulation middleware 110b and electrode 110a.In some embodiments, in skeleton The outer surface of 110c coats insulating coating, equally plays insulation crust 110d function, reduces the stray electrical current during seal tissue It concentrates.

Such as Fig. 1, jaw 120 is connected at the end 140b of elongated handle 140.With reference to Fig. 2 and 3, jaw 120 with 110 structure of jaw is different.Jaw 120 is the integrated design, and can pass through techniques production such as machining, metal injection molded molding etc. It arrives.In some embodiments, the surface (except the surface 120a of jaw 120) of jaw 120 is coated with one layer of coatings (such as Teflon, ceramic coating etc.) reduces the stray electrical current during sealing and concentrates.

The utility model is described in detail above by specific embodiment, which is only that this is practical new The preferred embodiment of type, the utility model are not limited to above embodiment.The case where not departing from the utility model principle Under, the equivalent replacement made such as shape, structure, material and improvement of the those skilled in the art to rolling Electrosurgical forceps should all regard For in the technology scope that the utility model is protected.
