Description
Technical field
The present invention relates to technical field of medical instruments, and in particular to one kind is rotatable to be repeated to be opened and closed hemostatic clamp.
Background technology
Endoscope hemostatic clamp is because its traumatic little, 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 reliability of blood, the active hemorrhage caused by Non-Variceal and visible vessels stump pathology, has obtained
Doctor and the accreditation of patient；Hemostatic clamp can also carry out closing the healing for promoting wound to gastral mucous membrane.
Existing hemostatic clamp can substantially divide three classes, the first kind to be that clip and device separate type hemostatic clamp, device can repeat
Use, clip is single use；Doctor uses every time and is required for Assembling, and can not repeat folding from new definition.Due to
GI wriggling, 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 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 is still relatively higher, will be repeated once operation once release mistake, and the time of patient is cured in delay.Operationally
Easier than first kind hemostatic clamp.3rd class hemostatic clamp is repeatable folding integral type hemostatic clamp, in human body natural's cavity
Interior can repeat folding, diseased region can be repositioned.As the rotation of such repeatable folding integral type hemostatic clamp is tied
Structure design and manufacturing process require to increase a part to realize spinfunction, are trapped in human body natural chamber after causing clip release
The partial-length in road is in 15.6mm or so；Due to 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.
Content of the invention
