A kind of medical shield structure cutter and using method thereofTechnical field
The present invention relates to medical operation device field, specifically a kind of medical shield structure cutter and using method thereof.
Background technology
Need in surgical procedures to carry out lock out operation, separation be appear field of operation dissect and removal lesion tissue, organ important essential surgical technique, should carry out according to normal structure gap as far as possible, carry out being separated at correct anatomy relationship is the key of performing the operation, can reduce hemorrhage, tissue injury, shortening time, operating equipment becomes the key factor of operation technique and art formula.
Be separated and can be divided into sharp property and passivity two kinds by form, sharp property is separated and refers to cutter or the anatomical isolation that sharp instruments carries out such as to cut, and being usually used in compact tissue such as aponeurosis (aponeuroses), sheath is separated with scar tissue etc.; Blunt separation is that the apparatuses such as detacher (as film clothing detacher, meninx dissector) by vascular forceps, closed dissecting scissors, handle of a knife, elevator, specific use or finger stretch into loose interstice, graduallys spread surrounding tissue lightly with suitable strength.Be usually used in the dissection of open texture as normal structure gap, comparatively loose adhesion, benign tumor or cyst peplos external series gap etc.
Finger separation is one of method commonly used in blunt separation, point the subjectivity carrying out being separated too strong, the proficiency level of surgical doctor and the extent of damage of histoorgan, how much hemorrhage, operating time length etc. have close relationship, easily cause the damage of vital tissue structure in separation process or tear, causing adverse consequences.
The operating theater instruments that surgical operation chorista is not separated simultaneously, rinses and clears up at present, many after separate tissue by clamp, cut off and remove tissue, what have is cut and organized by coagulation, the form such as to burn, surgical wound surface meeting residual fraction tissue, surgical anatomic region is clean and clear not, still do not adopt the form of shield structure tissue and vacuum cavitations power supply to carry out operation technique, guarantee operation safety, avoid organizing further damage.
