Description
[technical field]
The present invention relates to technical field of medical equipment, specifically a kind of clamping device and its operational approach.
[background technology]
With the development of endoscope treatment technology, the disease of many human body natural's tracts is generally carried out by endoscopic surgery
Treatment, wherein the mucosa infection defect bleeding of human body, the treatment of tract perforation are both needed to directly be treated using clamping device.Its
As a kind of physical mechanical method of disposal, first clamping device is imported into the human body by endoscope channel, using clamping dress
The mechanical pressure power for producing during the clamping part closure that puts, tissue and blood vessel are clamped in the lump, so as to close tissue and hemostasis,
Then the clamping part of clamping device is trapped in human lesion tissue up to organization healing, and the conveying operations portion of clamping device
Post operation withdraws from endoscope and human body.
In prior art, using following clamping device, clamping tissue carries out wound closure, hemostasis：
In patent documentation of the number of patent application that China announces for CN200980123274.7, a kind of hemostatic clamp is disclosed
Apparatus and method are held, the clamping device irrotationality rotation mechanism, it is impossible to which adjustment causes clamping effect poor with respect to the claming angle of tissue
Even clamping failure.
The utricule inner body of the clamping device is many and long, causes utricule longer, and too long of utricule is detained people and knows from experience stamp
The wound tissue relative with retaining part.
The jig arm of the clamping device is also easy to produce plastic deformation by deforming into utricule, repeats folding after-opening and diminishes, no
The larger tissue of method clamping.
In patent documentation of the number of patent application that China announces for CN201180059362.2, disclose that a kind of have can
The medical treatment device of dismounting pivotable jaws, the enclosure interior of the armarium is complex-shaped, outside to have four elongated slots as clamp
Guiding surface, quality of fit has high demands, and part processing and manufacturing is difficult, qualification rate is low, high cost, with other parts assemblies complexity
Difficult.
The clamp of the armarium are with structures such as little gears, and part processing and manufacturing is difficult, qualification rate is low, high cost, with
Other parts assemblies are complicated difficult.
The drive belts of the armarium have the structures such as tooth bar, and part processing and manufacturing is difficult, qualification rate is low, high cost, with
Other parts assemblies are complicated difficult.
In patent documentation of the number of patent application that China announces for CN201410222753.7, a kind of stopping is disclosed
Blood is pressed from both sides, and forms Detachable connection structure by buckle between the holder of the hemostatic clamp and transition cap, and the structure is more complicated, assembling is tired
Difficult, connection reliability is poor.
Between the transition cap of the hemostatic clamp and fixation, rotational structure, the rotational structure part are formed by transition cap mold insert
Many, assembling and connection are difficult.
The clamping limb of the hemostatic clamp is provided with the chute for coordinating with fixed pin shaft, and design of part is more complicated, assembles more difficult.
The clamping limb of the hemostatic clamp and afterbody crotch structure and the locking that convexes to form of holder, rely on back pull to make clamping limb
Elastic-plastic deformation, three part manufacturing tolerance scopes determine needed for back pull and reliable lock, in fact it could happen that after be pulled through
Big or too small, and cannot lock.
In patent documentation of the number of patent application that China announces for CN201310272522.2, a kind of clamping dress is disclosed
Put and its jaw part, the intermediate plate of the clamping device is also easy to produce moulding yield deformation by deforming into clamp pipe, and intermediate plate repeats out
Close after-opening to diminish, it is impossible to clamp big tissue.
The intermediate plate fixed seat of the clamping device and unlock piece axial length are longer, need in longer clamp pipe,
Too long of clamp pipe is detained human body, the tissue relative with retaining part of stabbing.
The intermediate plate fixed seat of the clamping device and unlock piece shape design complexity, the reed of clamp pipe is isostructure to be processed again
Miscellaneous, cost of parts height, Product Assembly difficulty.
It is thus desirable to a kind of clamping part of design can be departed from miscellaneous part, and combinative structure is more convenient, and grasp opening is big,
It is detained the short clamping device of length.
