Abstract
The utility model provides a hydrophily attracts radio frequency tool bit, establishing the sword shell of cavity in it, being equipped with the attraction pipe in tape spool hole in the sword shell cavity, attract the outside of tubes wall to be equipped with temperature measurement electrode, waterproof stopper and radio frequency output electrode, be located in the sword shell cavity and attract the other feed liquor pipe that is equipped with of pipe, its characterized in that attracts pipe front end to be equipped with the detachable pipe box, and the pipe box front end is equipped with the tool bit. Constantly carry normal saline to openning the surface of a wound through feed liquor pipe, simultaneously through attract pipe and radio frequency electrode to the liver open in step, the radio frequency stanchs and attract to bleed, and in the time need not attracting the function, overlap the pipe box in attracting the pipe front end, can for the hydrophily radio frequency sword of simplicity to the liver open, the radio frequency stanchs. Can be one with various livers operation cutter and the integration of operation mode, solve the big problem of liver surgery hemorrhagic volume, a thing is multi -purpose simultaneously.
Description
Technical field
This utility model relates to a kind of scalpel, and particularly a kind of hydrophily attracts radio frequency cutter head, belongs to surgical operating instrument design and manufacturing technology field.
Background technology
In current operation on liver, one of problem demanding prompt solution is the Excessive bleedings how reduced in operation process.Owing to being covered with a large amount of cancellated blood vessel and bile duct in liver organization, therefore very easily causing in operation on liver and bleed profusely, bring threat to the life of patient.Existing disconnected liver technology and cutter mainly contain: clamp method, high frequency electric knife, Ligasure
tM, ultrasonic attraction system and water cutter.Clamp method can control large footpath blood vessel, but easily causes minute blood vessel hemorrhage; High frequency electric knife, Ligasure
tMthe hemorrhage of closed minute blood vessel can be carried out by coagulation, but blood vessel in the liver that can not meticulously dissociate, easily cause scalpel to touch large footpath blood vessel wall and cause the problem of its bleeding due to trauma, also easily forming eschar affects haemostatic effect; The advantage of ultrasonic attraction system and water cutter can clearly dissociate blood vessel in liver, but shortcoming does not have coagulation function, and during operating cost.Therefore be necessary that research and development one can either know that solution cuts liver interior conduit, efficiently can stop blooding again and keep visual area surgical knife tool clearly.
Summary of the invention
In order to solve, there is coagulating effectiveness difference in existing operation on liver surgical knife tool used, operation is inconvenient, time-consuming and cause liver hemorrhage, thus threatening patient vitals security problems, this utility model provides a kind of hydrophily not only having possessed the hemostasis of hydrophily radio frequency but also had suction function concurrently to attract radio frequency cutter head.
This utility model is completed by following technical proposal: a kind of hydrophily attracts radio frequency cutter head, comprise in it cutter shell establishing cavity, the suction catheter of band axis hole is provided with in cutter shell cavity, suction catheter outer wall is provided with thermometric electrode, waterproof plug and radio frequency output electrode, be positioned at suction catheter side in cutter shell cavity and be provided with feed tube, it is characterized in that suction catheter front end is provided with dismountable pipe box, pipe box front end is provided with cutter head, to complete operation according to following needs: when needs synchronously complete incision, radio frequency hemostasis and when attracting hemorrhage, by feed tube constantly to incision wound surface conveying normal saline, simultaneously by suction catheter and radio-frequency electrode with the mode of operation of " scribbling ", liver is synchronously cut, radio frequency stops blooding and attracts hemorrhage, when not needing suction function, pipe box is placed on suction catheter front end, then synchronously can only cuts liver, radio frequency hemostasis.
Described cutter shell is set to the cylinder of band cavity, suction catheter is fixed in cutter shell cavity, suction catheter outer wall interval arranges thermometric electrode, radio frequency output electrode, suction catheter two ends outwards extend respectively, suction catheter front end is set to inclined-plane and forms sharp knife, rear end is connected with suction pump, to carry out liver incision and to attract hemorrhage operation.
Described feed tube is located in cutter shell cavity, and fixes feed tube in cavity by the waterproof plug in cavity, and feed tube front end is positioned at cavity, and rear end is connected with transfusion device through cutter shell, so that by feed tube conveying normal saline to wound surface.
Described thermometric electrode, radio frequency output electrode are connected with plug respectively by respective wire, then are connected with radio-frequency (RF) ablation main frame by plug.
Described pipe box comprises tail end and establishes uncovered, to establish cavity in it cylinder body, and be located at the cutting knife of body head end, pipe box is placed on suction catheter by uncovered, so that when not using suction function, pipe box is placed on suction catheter, namely can be exchanged into simple hydrophily radio frequency knife and use.
This utility model has following advantages and effect: adopt such scheme, can conveniently by feed tube constantly to incision wound surface conveying normal saline, simultaneously by suction catheter and radio-frequency electrode with the mode of operation of " scribbling ", liver is synchronously cut, radio frequency hemostasis and attract hemorrhage, and when not needing suction function, pipe box is placed on suction catheter front end, namely can be that simple hydrophily radio frequency knife cuts liver, radio frequency hemostasis.Various operation on liver cutter and modus operandi can be integrated into one, solve the problem that operation on liver amount of bleeding is large, there is the feature of one-object-many-purposes.Be a desirable surgical knife tool in fact.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model.
Detailed description of the invention
