Abstract
An operating scissors for treating anal fissure consists of two branches connected as integration via a central axle. Each branch consists of a shank and a cutting part. The operating scissors for treating anal fissure is characterized in that the cutting part of the operating scissors forms transverse bending on the same plane, relatively to the shank; the included angle between the shank and the cutting part is 160-185 DEG. The cutting part length of the operating scissors is 4-4.5 cm, and the length of the operating scissors is 12.5 cm. Because the utility model designs the operating scissors with peculiar angle and transverse bending cutting part, the size of the operative incision can be reduced at least 50% when the operating scissors are used in the anal fissure operation. Moreover, the anal canal isn't needed to cut off in operation, which injures patients lightly. The rectum can not be injured in operation because of apparatus, and the wound can be healed up ahead of time.
Description
Technical field
This utility model relates to a kind of surgical instruments, and particularly a kind of surgical operation cutting device operating scissors is used for the treatment of anal fissure.
Background technology
Anal fissure is a kind of common disease, and in the prior art, treatment anal fissure generally is with common operating scissors the about flesh of expansion of anal canal and periphery thereof to be cut off a part, defective with common operating scissors is that the otch of operation is big, and is also big to the damage of anal canal, hemorrhage more, wound healing is slow.The Chinese patent of publication number 2273174, application number 96214545.9 discloses a kind of operation on digestive tract and has cut, it has finger sleeve ring, handle of a knife, blade by two and forms one by axis, blade is a curved blades, angle α=75-90 between the extended line of its blade and the blade sweep °, distance L=4-6cm between the extended line of blade and the blade sweep top.This utility model is more suitable for the esophagus transverse section cut-out that low coverage is made the intestinal tube and the abdominal part of pelvic cavity, can not be used for the anal fissure treatment.
Technology contents
Technical problem to be solved in the utility model is at the deficiencies in the prior art, a kind of novel structure is provided, can dwindles operative incision and can have lowered the operating scissors that is specifically designed to treatment anal fissure to the damage of operative site greatly.
Problem to be solved in the utility model is to realize by following technical scheme.This utility model is a kind of operating scissors for the treatment of anal fissure, two branches that comprise the arranged coaxial that links into an integrated entity by axis, each branch is made of shank and blade, be characterized in, the blade of described operating scissors becomes horizontal bending on the same plane with respect to shank, and the angle that shank is become with blade is the 160-165 degree.Operating scissors described in the utility model is specifically designed to treatment anal fissure and uses, during operation, make a radial little otch at the about 3cm of distance anus edge place with the sharp knife sheet earlier, be about 0.5cm, reach subcutaneous deeply, holding the novel described operating scissors of this reality then inserts from incision, open operating scissors, make the distance of two blade blade tips of operating scissors be about 0.5-0.6cm (that is: making the outer ramose blade of operating scissors and interior ramose shank be in same horizontal level), again along the external sphincter subcutaneous part, cut off to interior while advancing, the external sphincter inter-drain changes the shear angle degree again, and the outer ramose blade of operating scissors is parallel with the rectum longitudinal axis and open and advance, insert anal canal with left index finger and guide this moment, preventing blade tip break-through anal canal, all cut off the head of internal sphincter with operating scissors, the row post surgery treatment gets final product when last.
Problem to be solved in the utility model can also further realize by following technical scheme.Above-mentioned a kind of operating scissors for the treatment of anal fissure is characterized in, the angle that shank is become with blade is 165 degree, and this angle is best angle.
Problem to be solved in the utility model can also further realize by following technical scheme.Above-mentioned a kind of operating scissors for the treatment of anal fissure is characterized in that the length of the blade of described operating scissors is 4-4.5 centimetre, and the length of described operating scissors is 12.5 centimetres.Like this, can make the size of this utility model operating scissors be controlled at the best, to be fit to the undergoing surgery degree of injury of reduction surgical wound surface.
Compared with prior art, this utility model is owing to designed the operating scissors that the blade of special angle laterally bends, when carrying out the anal fissure operation with this operating scissors, can make the size of operative incision reduce by 50% at least, and when undergoing surgery, need not cut off anal canal, damage to the patient is little, can be during operation technique because of apparatus does not damage rectum, and wound can heal in advance.
