Description
[technical field]
Technical field of medical equipment is the utility model is related to, specifically a kind of clamping device.
[background technology]
With the development of endoscope treatment technology, the illness of many human body natural's cavities is generally carried out by ESS
Treatment, wherein the mucosa infection defect bleeding of human body, the treatment of cavity perforation are both needed to directly use clamping device to be treated.Its
As a kind of physical mechanical method of disposal, clamping device is imported into the human body by endoscope channel first, filled using clamping
Mechanical pressure power caused by the clamping part closure put, 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 until organization healing, and the conveying operations portion of clamping device
Post operation withdraws from endoscope and human body.
In the prior art, wound closure, hemostasis are carried out using following clamping device, clamping tissue：
In the patent document that the number of patent application that China announces is CN200980123274.7, a kind of hemostatic clamp is disclosed
Apparatus and method are held, the clamping device irrotationality rotation mechanism, the claming angle relative to tissue can not be adjusted, cause clamping effect poor
Even clamping failure.
The utricule inner body of the clamping device is more 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, repetition folding after-opening diminishes, nothing by deforming into utricule
Method clamps larger tissue.
In the patent document that the number of patent application that China announces is CN201180059362.2, disclose that a kind of have can
Dismantle the medical treatment device of pivotable jaws, the enclosure interiors of the Medical Devices is complex-shaped, outside there are four elongated slots as clamp
Guiding surface, fit precision requires high, and part processing and manufacturing is difficult, qualification rate is low, cost is high, complicated with other component assemblies
It is difficult.
The clamp of the Medical Devices are with structures such as little gears, and part fabricates difficulty, qualification rate is low, cost is high, with
Other component assemblies are complicated difficult.
The drive belts of the Medical Devices have the structures such as rack, and part processing and manufacturing is difficult, qualification rate is low, and cost is high, with
Other component assemblies are complicated difficult.
In the patent document that the number of patent application that China announces is CN201410222753.7, a kind of stop is disclosed
Blood is pressed from both sides, and Detachable connection structure is formed by buckle between the holder and transition cap of the hemostatic clamp, and the structure is more complicated, assembling is tired
Hardly possible, connection reliability are poor.
Pass through transition cap mold insert between the transition cap of the hemostatic clamp and fixation and form rotational structure, the rotational structure part
More, assembling and connection are difficult.
The clamping limb of the hemostatic clamp is provided with the chute coordinated with fixed pin shaft, and design of part is more complicated, and assembling is more difficult.
The clamping limb and afterbody crotch structure of the hemostatic clamp and holder convex to form locking, make clamping limb by back pull
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
It is big or too small, and can not lock.
In the patent document that the number of patent application that China announces is CN201310272522.2, a kind of clamping dress is disclosed
Put and its jaw part, the intermediate plate of the clamping device are also easy to produce moulding yield deformation, intermediate plate repeats to open by deforming into clamp pipe
Close after-opening to diminish, big tissue can not be clamped.
The intermediate plate fixed seat and unlock piece axial length of the clamping device are longer, it is necessary in longer clamp pipe,
Too long of clamp pipe is detained human body, can stab the tissue relative with retaining part.
The intermediate plate fixed seat and unlock piece shape design of the clamping device are complicated, and the isostructure processing of reed of clamp pipe is multiple
Miscellaneous, cost of parts is high, and Product Assembly is difficult.
Therefore needing to design a kind of clamping part can depart from miscellaneous part, and combining structure is more convenient, and grasp opening is big,
It is detained the short clamping device of length.
