Description
Technical field
The present invention relates to the fixing device of seal wire and conduit used by a kind of intervention operation, more particularly to a kind of medical intervention
Conduit or seal wire fixation clamp.
Background technology
At present, intervention operation with its advantage such as minimally invasive, effective in fields such as cardiovascular and cerebrovascular disease, tumor and non-vascular diseases
Quickly carried out.In intervention operation, seal wire is the most basic equipment of operation, intervenes operation and can be applied to each of different size
Kind of seal wire, is more than 150cm the length of seal wire more, and, up to 300cm, most seal wires can be replaced in performing the operation on the same stage repeatedly should for more elder
With, and seal wire replace using when have part seal wire in placing resting state, now many leading resting state in clinic
It is placed in the disk for filling heparin saline after wire tray song, or to be placed in instrument table after gauze piece winding.But above processing means are equal
There is drawback, if seal wire is excessive, different seal wires is easily caused in being placed in same heparinate water pond and mutually wound, be not easy to take easily
Go out required seal wire, in addition long reinforcement seal wire be not easy to it is tortuous after be placed in disk；Grasp if all seal wires are with gauze piece winding
Make loaded down with trivial details, affect operative process.And above operation measure is easy to make in operation seal wire from sterile operating area
Lose in bacteria district, affect operation technique.
A kind of medical guiding wire clamper is disclosed in Chinese patent literature CN203842150U, which includes upper clamp, lower folder
Body and jointed shaft, its upper clamp and lower clamp are articulated and connected by jointed shaft, and the inner side of the upper clamp and lower clamp is matched somebody with somebody respectively
Upper engaging tooth and lower engaging tooth made by resilient material；It is furnished with clamping locking card on the inside of the upper clamp, in the lower folder
The correspondence position of body, is provided with the fixed hole clipping coordinated with adjustable locking card.Disclose in Chinese patent literature CN100466991C
A kind of blood vessel intervening guide wire holding protection equipment, its main body are one and constitute one by two pieces of hardened member that can carry out opening and closing movement
The fixture that can clamp seal wire is planted, the bindiny mechanism being associated with operation table frame is provided with fixture, its complex structure is not easy to face
Bed application and maintenance.Disclose a kind of for medical catheter or the clip of seal wire in Chinese patent literature CN201939853U, its
Structure is also complex, and including left clamp, right clamping body, rotating shaft and torque spring, above-mentioned left clamp and right clamping body mutually can be rotated
Ground is arranged in rotating shaft, and to grab the portion of pinching, left clamp and right clamping body are in and turn for the part of left clamp and right clamping body above rotating shaft
Part below axle is clamping part, and above-mentioned torque spring is enclosed within rotating shaft, and portion's phase is pinched with grabbing for left clamp in one end of torque spring
Connect, the other end of torque spring is connected with the portion of pinching of grabbing of right clamping body；It is respectively equipped with the clamping part of above-mentioned left clamp and right clamping body
Elastomer.Retaining part in these existing clamping devices is tabular or engagement dentation, and this structure directly clamps seal wire,
Such as clamp tension and may damage seal wire, especially micro-wire, open from the V-arrangement of two clamping plates as clamping slightly pine is likely to result in seal wire
Eject in mouthful, cause the pollution of seal wire.And in prior art, most clamping devices are only the clampings to seal wire, although some can
Conduit is applied to, but the tabular or engagement dentalation of its clamping part cause the more loose then clamping effect of clamping bad, clamp
Tight then be possible to conduit is caused to damage, severe patient can press off conduit, affect operation technique, thus the dynamics to clamping do not allow it is easily-controllable
System, operates with inconvenience.Additionally, existing clamping device cannot directly moisten hydrophilic seal wire, the seal wire clamped by which above
After taking-up, majority just can be applied after being both needed in heparin-saline moistening again again.Therefore, in the urgent need to one kind can be solved
The brand-new clamping device of above-mentioned technical problem.
