Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of rotatable hemostasis clamp device.
Background technique
Endoscope hemostatic clamp is because its traumatic small, anthemorrhagic speed is fast, bleeding event is low again, few intercurrent disease, curative for effect
The features such as, it has also become one of the 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 by Non-Variceal and visible vessels stump lesion is reliable, has obtained
The approval of doctor and patient；Hemostatic clamp can also be used to be closed gastral mucous membrane simultaneously, promote the healing of wound.It is existing
Hemostasis clamp device usually front end be detached from part be provided with symmetrical side opening, in order to which the hook guaranteed on intermediate plate can accurately enter
The size of side opening, general side opening is bigger, and when hemostatic clamp enters endoscope working clamp road, intermediate plate needs to be in closed state,
Due to endoscope enter after human body can as esophagus or enteron aisle are bent, the intermediate plate of closure when by endoscope corner,
The hook of side intermediate plate rear end may be stretched out by side opening, to scratch the pincers road inner wall of endoscope；Side opening size is larger, receives
Fixed pipe front end opens intermediate plate by the way that fixed pin is arranged, and not only the quantity of one-piece parts is more, also adds mach difficulty
Degree, meanwhile, the lower edges of side opening will form sharp blade, into human body after may scratch the cavity of inside of human body, add
The state of an illness of weight patient；The blade that the lower edges of side opening are formed is also possible to that the inside in endoscope working clamp road can be scratched, and causes
The electric system of endoscope, which seeps water, to be damaged, so as to cause the failure of operation.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of rotatable hemostasis clamp device, pass through
Cavity is set by the side opening for tightening casing, while second step is set in cavity, tightening casing is can effectively prevent and scratches

First step 1-62, internal diameter of the first step 1-62 outer diameter greater than fixing sleeve 1-5, and first step 1-62 internal diameter, which are less than, to be turned
The internal diameter of axis 1-6；The front end the shaft 1-6, which is symmetrically arranged with, to extend outwardly and deformable first position-limited edge 1-61, and described first
Position-limited edge 1-61 is set in the hook cavity 1-34 at the tightening rear portion casing 1-3, and the maximum between the first edge position-limited edge 1-61
Distance is greater than the internal diameter of annular base 1-31.The first step 1-62 of shaft 1-6 is connected to the rear end of fixing sleeve 1-5, the first limit
Position side 1-61 is connected to the front end annular base 1-31, and shaft 1-6 is made to realize axial restraint, radial rotary；The of the front end shaft 1-6
One position-limited edge 1-61 uses metal material, when the rearward pulling force of application is greater than predetermined force, makes the first position-limited edge 1-61 that shape occur
Become, at this point, the first position-limited edge 1-61 and annular base 1-31 is detached from.
Further, the traction element 3 further includes butt tube 3-1, and the butt tube 3-1 outer diameter is less than first step
1-62 internal diameter, the front end the drag-line 3-2 are fixedly connected by butt tube 3-1 with the rear end pull rod 1-7.
Further, there are two the pull rod 1-7 is set, the front pull rod 1-7 is connect with middle part in 150 ° of angles, two pull rods
1-7 constitutes Y shape, and middle part is provided with location hole 1-72 and welding hole 1-73 up and down, and rear portion is welded on inside butt tube 3-1,
The front pull rod 1-7 front end is deformable crook 1-71, is equipped with short pin in two pull rod 1-7 crook 1-71
1-8 is followed closely, two crook 1-71 are respectively arranged on the both ends of dump bolt 1-8, also wear in the middle part of the dump bolt 1-8 by two
The length of a middle and back the intermediate plate 1-4, the dump bolt 1-8 is greater than second step 1-32 back end inside diameter.Intermediate plate 1-4 is used
Material with certain elasticity is made, and is still able to maintain whole complete after so that intermediate plate 1-4 retraction is tightened casing 1-3, and is tightening
Under the action of casing 1-3 inner wall, the end hook 1-41 of intermediate plate 1-4 is forced outwardly；Pull rod 1-7 uses metal material, hook
When shape portion 1-71 is greater than predetermined force by pulling force backward, the crook 1-71 of pull rod can be straightened disengagement or fracture.
Further, the first position-limited edge 1-61 and the second position-limited edge 1-33 is assembled by clamp die mould technique.
Further, the front end the fixing sleeve 1-5 is provided with outwardly extending flange, the outer diameter and bourdon tube of the flange
1-2 outer diameter is identical, and the outer diameter of fixing sleeve 1-5 is identical as the internal diameter of bourdon tube 1-2.
In use, made in the part intermediate plate 1-4 income tightening casing 1-3 by pulling back handle component 2, it at this time will only
Blood folder front end by the working clamp road of endoscope enter human body reach affected part, reach affected part be pushed forward backward fixed handle component 2 thus
Intermediate plate 1-4 is discharged, rotating handle component 2 drives the components such as tightening casing 1-3 to carry out rotational positioning, controls hand after the completion of positioning
Shank part 2 pulls back drag-line 3-2, so that intermediate plate 1-4 be driven to be closed, repressive hemostasis will be carried out at bleeding, links up with 1-41
In hook cavity 1-34；It is gradually increased 2 pulling force of handle component, after being greater than second step 1-32 due to dump bolt 1-8 length
Internal diameter is held, dump bolt 1-8 is stuck in the front end second step 1-32, and when pulling force is greater than predetermined force, pull rod 1-7 crook 1-71 is drawn
Straight or fracture, the hook 1-41 of the rear end intermediate plate 1-4 tangle the rear end of the second step 1-32 in tightening casing 1-3, pull on
Drag-line 3-2 is detached from pull rod 1-7 inside tightening casing 1-3, into shaft 1-6 internal cavities, until by the first position-limited edge
1-61 is pulled to deformation, separates tightening casing 1-3 with components such as bourdon tube 1-2, intermediate plate 1-4 and tightening casing 1-3 interaction
Bleeding portion mechanical pressure is stopped blooding, rest part is exited by endoscope working clamp road, completes hemostasis task.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present invention
Within.
