Description
Technical field
The present invention relates to scalpel technical field more particularly to a kind of anal fistula operating knifes.
Background technique
Anorectal fistula mainly invades anal canal, is seldom related to rectum, therefore is commonly referred to as anal fistula, refers to the granulation of perianal
Swollen property pipeline, is made of internal orifice, fistula, collar extension three parts.Internal orifice is frequently located in rectum lower part or anal canal, mostly one；Collar extension exists
It can be one or more on anal skin, not recover for a long time or intermittent recurrent exerbation, fistula is by reactive dense fibrous tissue
It wraps, is inflammatory granulation tissue at nearly lumen, is common one of anorectal disease.Anal fistula is unable to self-healing, and not treating can be anti-
Perianorectal abscess is made in recurrence, it is therefore necessary to operative treatment.Traditional Treatment of Anal Fistula operation has syringotomy, hanging wire to treat
Method and anal fistulectomy, syringotomy are all to cut fistula to open, and grow the method to cicatrize a wound by granulation tissue,
Suitable for low level anal fistula, because fistula in external sphincter deep hereinafter, only damage Subcutaneous section of external shincter muscle and superficial part after cutting, will not
There is postoperative anal incontinence；Ligating method for treating anal fistula is acted on using the mechanical pressure of rubber band or the medicated thread for having corrosiveness, slowly
The advantages that method for cutting anal fistula, skin incision bonding will not occur before rubber band falls off for the method；Anal fistulectomy is to cut
Open fistula and by fistula wall complete resection to health tissues, the surface of a wound not sutures, if the surface of a wound is larger, can partially suture, and part is spacious
It opens, inserts oil gauze, make the surface of a wound is outward from the bottom to grow to healing, be suitable for simple low anal fistula.
Traditional principle of reatment is all to cut fistula, forms the open surface of a wound, rejects the lesions groups such as fistula wall by hand
It knits, then makes wound growth healing.There are many modus operandi, and operation should be according to the height, fistula and anal sphincter of internal orifice position
Relationship select, the key of operation is to try to reduce the damage of anal sphincter, prevents fecal incontinence, while avoiding anal fistula
Recurrence.But traditional anal fistula surgical wound is big, amount of bleeding is big, and the pain of patient is big, and treatment time is long, restores slow, leaves very
The big edge of a knife, influences beauty.
Summary of the invention
The technical problems to be solved by the invention and the technical assignment of proposition are improved to the prior art, and one kind is provided
Anal fistula operating knife solves anal fistula operation traditional in current technology by the way of fistula incision, and wound is big, and treatment time is long,

It can stablize on pole one and generate plasma, ensure that operative stabilization is implemented.
Further, the side wall on elongated tubular at insulative head, elongated tubular and electrode one is arranged in the apopore
Conducting apart from short, it is ensured that physiological saline can effectively be connected elongated tubular and electrode one, ensure that anal fistula operating knife is stablized and work normally.
Further, the apopore is along the circumferential direction uniformly arranged, so that water outlet is uniform in whole circumference direction, is made
The plasma all on whole circumference direction on electrode one with high concentration is obtained, avoids local plasma concentration on electrode one too low
And lesion tissue can not be effectively melted, eliminate treatment dead angle, it is ensured that entire fistula can be cleaned, and improve therapeutic effect.
Further, seal chamber is provided on the handle, elongated tubular is perforated through seal chamber and connect with power supply wiring, defeated
Liquid pipe penetrates in seal chamber, and the tube wall of elongated tubular has opened up blasthole, so that physiological saline stabilization enters in elongated tubular, avoids
Physiological saline, which leaks into handle, leads to equipment Damage by Short Circuit.
Further, the junction of the elongated tubular and seal chamber is provided with sealing device, improves leakproofness, avoids giving birth to
Reason salt water leakage leads to accidental shock, improves safety in utilization.
Further, it is provided with flow regulator on the perfusion tube, physiological saline is adjusted according to operation demand
Supply flow rate ensures that operative stabilization carries out.
Compared with prior art, the invention has the advantages that:
Anal fistula operating knife of the present invention destroys lesion tissue using Inferior turbinate hypertrophy, decomposition, reaches the mesh for the treatment of
, plasma makes tissue vaporization, rather than high temperature coagulation is downright bad, and it is small to myoneural tissue damage, it is relatively low
Temperature makes cutter head be reduced to minimum to the damage of tissue, and sphere of action limitation, minimally invasive, pain is minimum, and amount of bleeding is small, operation
Time is short, alleviates postoperative pain, and postoperative aesthetics is good；Electrode one is in mushroom head, at electrode one side edge it is equal from
Sub- concentration highest can effectively melt by twitching cutter head in the fistula of anal fistula, decompose fistula wall, cleaning without dead angle,
