Description
Technical field
The utility model is related to technical field of medical instruments, and in particular to a kind of rotatable repetition opening and closing hemostatic clamp.
Background technology
Endoscope hemostatic clamp is because its traumatic small, anthemorrhagic speed is fast, bleeding event is low again, few intercurrent disease, determined curative effect
The features such as, it has also become one of hemostasis means of the relatively broad application of critical patient.Hemostatic clamp is that a kind of physical mechanical is repressive only
The hemostatic treatment effect of blood, the active hemorrhage caused to Non-Variceal and visible vessels stump lesion is reliable, has obtained
Doctor and the accreditation of patient；Hemostatic clamp can also carry out the healing that closure promotes wound to gastral mucous membrane.
Existing hemostatic clamp can substantially divide three classes, and the first kind is clip and device separate type hemostatic clamp, and device can be repeated
Use, clip is disposable；Doctor uses be required for Assembling every time, and can not repeat folding from new definition.Due to
The wriggling of intestines and stomach, it is difficult to be accurately positioned to lesion portion.If clip off-position mistake, will be repeated once above-mentioned behaviour
Make, the quality time of patient is cured in delay.Operation is required for the processing that carries out disinfection to device every time, if sterilization is improper to have intersection sense
The risk of dye.Equations of The Second Kind is clip and device integral type hemostatic clamp, it is impossible to repeat folding from new definition, clip off-position is forbidden
True probability still compares high, and operation will be repeated once once release mistake, and the time of patient is cured in delay.Operationally
It is easier than first kind hemostatic clamp.3rd class hemostatic clamp is repeatable folding integral type hemostatic clamp, in human body natural's cavity
It is interior to repeat folding, diseased region can be repositioned.Due to the rotation knot of such repeatable folding integral type hemostatic clamp
Structure is designed and manufacturing process requires one part of increase to realize spinfunction, causes clip to be trapped in human body natural's chamber after discharging
The partial-length in road is in 15.6mm or so；Due to product structure, its chuck afterbody for being detained human body natural's cavity has ratio
Sharp projection, easily causes the risk of perforation.
