Detailed description of the invention

For the ease of the understanding of those skilled in the art, be further described this utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.

Shown in Fig. 3, closed, the cutting electrode of electrosurgery of the present utility model, comprises binding clip 1 and clamp handle 2, the sheathed claw beam 3 in described binding clip 1 rear end, and is screwed in binding clip 1 rear end, described clamp handle 2 is rotary with interior bar 4; Described claw beam 3 is sheathed on interior bar 4, and is screwed in clamp handle 2; Described binding clip 1 is provided with cutter.

Described clamp handle 2 is provided with rotating wheel 21, start button 22, cutting trigger 23 and handle 24.

Described interior bar 2 and claw beam 3 are all screwed in clamp handle 2 by rotating wheel 21.

Described clamp handle 2 is connected with high frequency lead plug 6 by bipolar electric synezis 5.

Described high frequency lead plug 6 exterior material adopts medical grade 70G10HL nylon, and integral ultrasonic is welded; Back panel wiring terminal adopts pyrite machining.

Described binding clip 1 can be 10MM friction clamp head, 10MM curved forceps head, the large curved forceps head of 10MM and 5MM friction clamp head; Described cutter are of a size of length 50mm, width 2mm, thickness 0.4mm.

Electrosurgery of the present utility model using method that is closed, cutting electrode, step is as follows:

Step one: be placed in by binding clip 1, clamp handle 2, claw beam 3 and the interior bar 4 after splitting after multienzyme liquid soaks 1-10 minute, use giant to clean tube chamber inside, use compressed air to dry up or dry, then carry out disinfection sterilizing;

Step 2: after electrode assembling is good, the plug of electrode is plugged on high frequency generator, and selects suitable set value of the power;

Step 3: frontly push away electrode flexible handle, makes jaw open, the blood vessel needed for clamping and tissue, and makes its optimal number of organizing clamped between jaw be 2/3 of jaw;

Step 4: rotation electrode rotates the swiveling wheel of clamp handle front end, control electrode jaw opens or closes and carries out organized processing and dissection, closed vascular and tissue bundle.

Procedures electrode needs simple and efficient operation in operation, design not only can control by the foot switch connecting main frame to export and stop, and can control to export and stop by manual switch, manual switch needs eye-catching color to remind operator to note using, therefore require that the manual start button of apparatus is at handle end, start button color is blue simultaneously, flexible and convenient operation.

The position of standing due to the change of operative site and operator in operation is moved needs procedures electrode to have good position transformation function, therefore requires the angle increasing rotating wheel: rotate the knob on handle, claw beam can be done to be not less than 320 degree of rotations.

Need in operation to remind the state residing for the current apparatus of user at any time, therefore requirement sends the sound to remind the state residing for the current apparatus of user after closing, and requires that binding clip opening and closing should be flexible, must not have clamping stagnation, loosens phenomenon.Close handles, electrode should be able to send " click clatter " sound, and prompting is completely closed.

Simultaneously require that apparatus can be reused to reduce use cost, require detachable product, electrode dismounting should be flexible, should firm non-loosening after assembling.

Product major function is blood coagulation and cutting and organizing in operation, owing to using blade cuts tissue, the hardness of the blade just required in operation wants high, and surface roughness is little, and therefore in technical specification, we require: apparatus cutter case hardness is not less than 350HV0.2.Cutter surface roughness Ra should be not more than 0.8 μm.

Propose the requirement of Interface Electrical reliability: the electrode conduction between binding clip electrode and high frequency lead plug, during switch connection on handle, resistance is should≤5 Ω simultaneously.>=1M Ω is answered during disconnection.

The requirement of interface Mechanical Reliability: should be connected firmly between wire and electrode, the pulling force 15s applying 20N should not rupture.

Material corrosion resistance requires: binding clip electrode and cutter corrosion resistance should be able to reach the b level requirement of boiling test law regulation in YY/T 0149.

Biocompatibility requirement: with the binding clip electrode of human contact and the requirement of cutter: cytotoxicity is not more than 1 grade should without delayed hypersensitivity, should without Intradermal irritant reaction.
