Electric coagulation type planing knifeTechnical Field
The utility model relates to a medical high-speed cutting surgical instruments technical field, concretely relates to electricity congeals formula planing sword.
Background
In recent years, electric shavers have been widely used in foreign countries for surgical treatment of the sinuses, throat, and bronchus, and have been proven to have excellent effects: (1) excellent control and accurate excision of soft tissue; (2) the surrounding tissue is protected because only the tissue in the hole can be cut and excised; (3) increased visibility because blood and debris can be aspirated from the surgical field. However, in the high-speed cutting process, the bleeding of tissues can occur, and the cutter is replaced to stop bleeding, so that the operation time is increased virtually, the risk of the operation process is increased, and the pain is brought to patients. Accordingly, there is a need for those skilled in the art to develop an electrocoagulation type planing tool.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the deficiencies existing in the prior art, providing an electric coagulation type planing knife, which can coagulate blood for tissues, improve the accuracy of operation and improve the operation quality.
In order to achieve the purpose of the utility model, the utility model provides a technical scheme as follows: the utility model provides an electricity congeals formula planer tool, this planer tool include handle of a knife portion, cutter arbor, insulating sheath, electrode holder, most advanced electrode, outer sword pipe and inlayer attraction sword pipe, the cutter arbor adaptation sets up in handle of a knife portion one end, cutter arbor one end is provided with outer sword pipe and inlayer attraction sword pipe, the inlayer attraction sword pipe sets up in outer sword intraductal side, the outer sword outside of tubes is provided with the electrode holder, be provided with most advanced electrode on the electrode holder, insulating sheath sets up in the cutter arbor outside, the clearance is established to the notes mouth of physiological saline water droplet between outer sword pipe and the inlayer attraction sword pipe.
Preferably, the tip electrode is in the form of a wire or a sheet or a ring made of a refractory metal or an alloy thereof.
Preferably, the electrode holder is made of heat-resistant insulating material, and the heat-resistant insulating material is ceramic or high-temperature plastic.
Preferably, a power cable is arranged at one end of the cutter bar, the power cable penetrates through the cutter bar and is electrically connected with the tip electrode, and the other end of the power cable is connected with external equipment.
Preferably, the insulating sheath is made of PTFE, PVC or PE.
Preferably, the cutter bar is integrally formed by a stainless steel pipe.
Preferably, the outer layer knife pipe and the inner layer suction knife pipe are both processed by stainless steel.
Based on the technical scheme, compared with the prior art, the utility model have following technical advantage:
the utility model discloses an electricity congeals formula planer sharpener, structural design is reasonable, when excising pathological change tissue, to the tissue electricity congeals hemostasis, reduces the painful sense of operation time and patient, guarantees the degree of accuracy and the effect of operation, improves the operation quality.
Drawings
Fig. 1 is a schematic structural view of the electric coagulation type planing tool of the present invention.
Fig. 2 is an enlarged schematic view of the front end of the electrocoagulation type planing tool of the present invention.
In the figure: 1. the device comprises a cutter handle part, a cutter rod 2, aninsulating sheath 3, an electrode seat 4, atip electrode 5, an outerlayer cutter tube 6, an inner layersuction cutter tube 7, apower supply cable 8 and a physiological saline water drop injection port 9.
Detailed Description
The invention is further explained below with reference to the drawings and examples.
As shown in fig. 1-2, an electrocoagulation type planing tool comprises atool shank portion 1, a tool bar 2, aninsulating sheath 3, an electrode holder 4, atip electrode 5, anouter tool tube 6 and an inner layersuction tool tube 7, wherein the tool bar 2 is adapted to be arranged at one end of thetool shank portion 1, theouter tool tube 6 and the inner layersuction tool tube 7 are arranged at one end of the tool bar 2, the inner layersuction tool tube 7 is arranged at the inner side of theouter tool tube 6, the electrode holder 4 is arranged at the outer side of theouter tool tube 6, thetip electrode 5 is arranged on the electrode holder 4, theinsulating sheath 3 is arranged outside the tool bar 2, thetip electrode 5 extends out of theinsulating sheath 3, and a gap between theouter tool tube 6 and the inner layersuction tool tube 7 is set as a physiological saline drip injection port 9.
Thetip electrode 5 is made of high-temperature-resistant metal or alloy thereof and is in a wire shape, a sheet shape or a ring shape. The electrode seat 4 is made of heat-resistant insulating material, and the heat-resistant insulating material is ceramic or high-temperature plastic. Apower cable 8 is arranged at one end of the cutter bar 2, and thepower cable 8 penetrates through the cutter bar 2 and is electrically connected with thetip electrode 5. The insulatingsheath 3 is made of PTFE or PVC or PE. The cutter bar 2 is integrally formed by a stainless steel pipe. The outerlayer knife pipe 6 and the inner layersuction knife pipe 7 are both made of stainless steel.
When the motor works to drive the inner layersuction knife tube 7 to chip the lesion tissue at high speed, the suction port of the inner layersuction knife tube 7 sucks out the lesion tissue, and when the tissue bleeds, thetip electrode 5 on the outer side of the outerlayer knife tube 6 is used for electric coagulation hemostasis, so that the operation process is smoothly completed.
The foregoing is illustrative and explanatory of the invention and is not intended to limit the advantages attainable thereby, and it is within the scope of the present application to practice the invention with simple modifications to the structure and/or one or more of the advantages achieved in some embodiments.
