Description
Technical field
The utility model is related to scalpel technical field more particularly to a kind of plasma debridement surgical knives.
Background technology
Debridement is method surgically, removes the foreign matter in open wound, excision necrosis, inactivation or is seriously polluted
It organizes, sew up a wound, be allowed to reduce pollution to the greatest extent or even become clean wound, reach first intention, the work(of advantageous injury
It can be with the recovery of form.Debridement is a kind of operation of surgery basic operative, the quality of wound initial stage processing, to wound healing, by
The recovery of the function and form of traumatic part bit organization plays a decisive role, and when debridement should thoroughly cut off the tissue to have lost vigor,
It cherishes and retains the tissue of survival as possible again, be just avoided that wound infection in this way, promote healing, preserve function.
Debridement mode traditional at present has surgical debridement, biochemical debridement and mechanical debridement, and surgical debridement is profit
Surgically mode clears up wound slough, and debridement is more thorough, but has bleeding, the possibility for damaging normal structure, suffers from
Person's pain, it is impossible to be resistant to；Biochemical debridement is to spread on wound using water active dressing, enzyme preparation etc., except the tissue that depollutes, but is needed
Will regular debridement repeatedly, long time period, it is often necessary to consider the safeguard measure of skin, part enzyme preparation price；It is mechanical clear
Creating main mode has hydrotherapy douche, easy to operate, just with brine or cleaning agent to be vortexed or backwashing manner cleans the surface of a wound
Victory, but low-pressure flushing effect is poor, high pressure may damage active tissue.Traditional debridement mode is less efficient,
And debridement is not thorough, and patient pain is severe, difficult to scar tissue.

Into stable plasma thin layer, debridement treatment can be accurately carried out, when only emitter comes close to or in contact with human body wound tissue
Ablation, the resolution process of plasma could be carried out, to tissue when efficient playing debridement work, and minimizing debridement
Degree of injury.
Further, the emitter protrudes from 2~5mm of front end of circuit pole, and physiological saline flows through emitter with returning
Circuit pole and emitter are connected when between the pole of road and forms stable plasma thin layer.
Further, the circuit pole, emitter are located on the front end face of insulating base, are conveniently operated, and ensure at debridement
The accuracy of reason.
Further, the emitter protrudes from the front end face of insulating base or emitter is less than the front end face of insulating base
0.2~1mm, emitter protrude from the front end face of insulating base, and wound surface is gently scraped by emitter, and cleaning plasma can be assisted clear
Human tissue surface after wound ensures debridement completeness；Simultaneously when emitter is less than 0.2~1mm of front end face of insulating base, both
Ensure debridement efficiency, and will not be damaged to patient and pain.
Further, the suction hole is located on circuit pole and the same end face direction of emitter, is generated after debridement
Discarded tissue through normal saline flushing, is attracted by suction hole and walks waste, completes the Overall Steps of wound cleaning.
Further, the aperture of the suction hole is less than 2~3mm of emitter, and guarantee can siphon away rapidly debridement waste
While, suction hole and the contact of the human body surface of a wound are also avoided, reduces debridement treatment to pain caused by patient.
Further, the pass of the suction hole is semicircular arc, avoids and causes mechanical trauma during human contact, is dropped
Low debridement treatment is to pain caused by patient.
Further, the aperture size of the suction hole is 10mm*3mm, effectively siphons away debridement waste.
Compared with prior art, the utility model advantage is：
Plasma debridement surgical knife described in the utility model using Inferior turbinate hypertrophy, decompose destroy wound foreign matter and
Slough becomes clean wound, reaches first intention, the recovery of the function and form of advantageous injury, and plasma makes group
Vaporization rather than high temperature coagulation necrosis are knitted, small to myoneural tissue damage, relatively low temperature makes cutter head to group
The damage knitted is reduced to minimum degree, and sphere of action limitation, minimally invasive, pain is minimum, and amount of bleeding is small, and the debridement efficient time is short,
Postoperative pain is alleviated, debridement is thorough, and effectively scar tissue can be handled, and debridement treatment accuracy is high, minimizes clear
To the degree of injury of tissue during wound, the bacterium of wound surface can be killed, is not easily accessible in debridement simultaneously for drug
Human body wound tissue have preferably and direct bactericidal effect.
