Description
Technical field
The invention belongs to a kind of incision surgical knifes, belong to technical field of medical treatment mechanical.
Background technique
Mucous membrane decollement is that new treatment means and potential applicability in clinical practice occurring in recent years are good under scope
More early stage digestive system cancers disposable on scope can be cut off completely, the pain and device of abdominal are eliminated for technology
The excision of official, the important surgical instrument of mucous membrane decollement is mucous membrane incision knife under scope.It is commonly used in early cancer removing in the market
Incision knife have needle knife, IT knife (band ceramic head), billhook, triangular knife, Flush knife (flushing hole is equipped in cutter head), woodpecker knife
Deng.
As Alimentary tract disease treatment in important means, doctor during mucous membrane decollement under carrying out scope, in order to
It prevents from causing to perforate in surgical procedure, usually first lesions position can be marked using mucous membrane incision knife, then replace injection needle
The injection of physiological saline under mucous membrane is carried out to raise the position of lesion, then replaces mucous membrane incision knife and lesion is removed.So
Doctor in the course of surgery, can frequently replace surgical instrument, to meet the different needs of each operation.But frequent operation
Instrument replacement, it is not only loaded down with trivial details but also time-consuming, it is unfavorable for patient's operation, and the physiological saline injected in the course of surgery can be with operation
Time and be lost, need again this process of injecting normal saline that can waste a large amount of time, will increase due to operation in physiology
Salt water, which is lost, cannot obtain being replenished in time the risk for increasing operation middle punch and the time for extending surgical procedure.
Currently, having a kind of patent discloses a kind of combination electric knife, cutter head portion includes at least two or more than two mutually
Between the cutter head that can relatively move or rotate, doctor can be according to analyzing the case where lesions position tissue and judge using suitable
The different conditions of electric knife choose suitable electric knife type to the tissue of lesions position, make surgical procedure safely and fast；Also there is patent
A kind of utility knife that IT knife and needle knife and water spray is combined is disclosed, has the function of IT knife and needle knife function, also there is spray
Water function, the liquid of ejection can rinse blutpunkte, improve the scope visual field, can also rinse the charred tissue adhered on electrode；
A kind of integrated scheme is disclosed there are also a kind of patent, the function of mucous membrane incision knife and injection needle is combined, reduces surgical instrument
The time of replacement saves surgical energy,
This time for needing that there is multi-functional combination incision knife to save replacement instrument.Above-mentioned two patents may be implemented
Doctor is changed without electric knife and facilitates and select different electrotome heads, or realizes that spraying function improves the internal diameter visual field, or is to realize
The time that instrument is replaced when mark, injection, removing is reduced, but entire surgical procedure is still long.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is provide it is a kind of integrate thulium knife,
Water filling, snare function solid type mucous membrane incision knife effectively can avoid perforating and improve hand under scope in mucous membrane removing operation
Art efficiency solves the problems, such as to propose in background above technology.
The technical scheme adopted by the invention is as follows: a kind of Multifunction cutting is operated on, comprising:
