Description
Technical field
The present invention relates to medical operation device field, specifically a kind of medical shield knife and its application method.
Background technology
Need to carry out lock out operation in surgical procedures, separation is to appear field of operation dissection and removal lesion tissue, device
The important essential surgical technique of official, should try one's best and be carried out according to normal structure gap, and it is hand to carry out separation in correct anatomy relationship
The key of art, it is possible to reduce bleeding, tissue damage, shortening time, operating equipment turns into the key factor of operation technique and art formula.
Separation can be divided into two kinds of sharp property and passivity by form, and sharp property separation refers to knife or the solution that sharp instruments are carried out such as cuts
Subdivision is from being usually used in the separation of compact tissue such as aponeurosis (aponeuroses), sheath and scar tissue etc.；Blunt separation vessel forceps, closure
Dissecting scissors, handle of a knife, elevator, the stripper of specific use（Such as film clothing stripper, dural dissector）Stretched into Deng apparatus or finger
Loose tissue space, surrounding tissue is lightly gradually spread with appropriate strength.It is usually used between open texture such as normal structure
The dissection of gap, more loose adhesion, benign tumour or tumour coating external series gap etc..
Finger separation is one of method for commonly using in blunt separation, and the subjectivity that finger is separated is too strong, surgical doctor
Qualification and the extent of damage of histoorgan, how many, the operating time length of bleeding etc. there is close relationship, separation process
In easily cause the damage or tear of vital tissue structure, cause adverse consequences.
Surgical operation chorista is currently without separation simultaneously, the operating theater instruments rinsed and cleared up, more after tissue separation
By clamp, cut off and remove tissue, have by coagulation, the form such as burn and cut tissue, surgical wound surface can residual fraction tissue,
The not enough cleaning of surgical anatomic region and clear, the progress operation behaviour still not in the form of shield tissue and vacuum cavitations power supply
Make, to ensure operation safety, it is to avoid tissue further damage.
The content of the invention
