Description
Technical field
This utility model relates to intervention armarium, refers in particular to the medical guiding wire of a kind of intervention.
Background technology
Interventional therapy is a kind of invasive treatment utilizing modern high tech method to carry out--be exactly under the guiding of medical imaging device, by special conduit, the precision instruments such as seal wire, introduce human body, diagnose and topical therapeutic morbid state in body.Interventional therapy Applied Digital technology, expand the visual field of doctor, by conduit, seal wire extends the both hands of doctor, its otch (point of puncture), only there is grain of rice size, need not tissue be cut, just can treat and manyly cannot to treat in the past, must operative treatment or the not good enough disease of medical treatment curative effect, as tumor, hemangioma, various hemorrhage etc.
Current, the guiding wire that intervene operation uses, adopts stainless steel silk and stainless steel spring surface to be coated with PTFE and hydrophilic coating usually.Utilize X-ray development to observe seal wire during operation and enter human body and pathological changes situation.In operation process, all observe seal wire by X-ray development due to needs and enter human body situation, easy discrete surgical doctor attention, increase operating time, have certain operation risk, therefore, need a kind of guiding wire with tagged architecture.
Application number be 200910080762 Chinese invention patent disclose " a kind of guiding wire ", this patented technology is provided with spring housing at the far-end of guiding wire, and conical section is fixed on spring housing, thus make guiding wire possess certain rigidity and flexibility simultaneously, but its defect existed is that spring housing is only arranged on the end of guiding wire, its limited length, therefore the flexibility of its far-end is not high, and the situation far away for pathological changes is not suitable with; Meanwhile, the external diameter of conical section is less, when being therefore connected with spring housing, not stressed, connects insecure, and junction is positioned at the far-end of guiding wire, if occurring connecting after guiding wire gos deep into blood vessel during operation loosens, intractability is large.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of reasonable in design, the medical guiding wire of the intervention that application is strong.
The technical scheme that this utility model is taked is as follows: the medical guiding wire of a kind of intervention, it is characterized in that: comprise seal wire skin, guidewire core and spring housing, wherein, above-mentioned seal wire outer layer covers is outside in above-mentioned guidewire core, form guiding wire, this guiding wire is arranged on near-end, and the outer field space outside of seal wire arranges at least two Marking rings, to observe guiding wire move distance; The outer field far-end of above-mentioned seal wire is fixedly connected with by the inwall of adapter sleeve with above-mentioned spring housing, and above-mentioned guidewire core stretches out the outer field far-end of seal wire, extends in above-mentioned spring housing.
Preferably, described spring housing distally extends, and the end face of spring housing is provided with plumb joint.
Preferably, described guidewire core runs through spring housing, and the far-end of guidewire core and spring housing is fixed together by plumb joint, and the end face of plumb joint is curved surface, to prevent from damaging when advancing blood vessel.
Preferably, the outer field far-end of described seal wire stretches in spring housing, is provided with adapter sleeve between the outer field outer wall of seal wire and the inwall of spring housing, and seal wire skin and spring housing are connected and fixed by adapter sleeve.
Preferably, the external coated of described Marking ring has hydrophilic coating.
The beneficial effects of the utility model are:
This utility model employing near-end is the combining form of seal wire skin and guidewire core, far-end is the combining form of spring housing and guidewire core, by the seal wire of near-end, outer and guidewire core ensure that the rigidity of guiding wire and turns round control, be ensure that flexibility and the elasticity of guiding wire by the spring housing of far-end and guidewire core; Meanwhile, only spring housing is arranged on the structure of distal end relative to conventional lead seal wire, the length of guiding wire spring housing of the present utility model is longer, and flexibility is better; In addition, the seal wire skin larger by external diameter is fixedly connected with spring housing inwall, than conventional lead seal wire seal wire external diameter smaller part connect greatly stressed, be connected firmly, safety coefficient is higher, and junction point is positioned at near-end, even if therefore occur that seal wire outer connection with spring housing loosens, there is disengaging situation, be also convenient to the spring housing departed to take out.
In addition, this utility model is also provided with at least two segment mark rings at the near-end of guiding wire, and Marking ring is arranged on the outer field outside of seal wire, when being convenient to operation, observes the move distance of guiding wire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described:
As shown in Figure 1, the technical scheme taked of this utility model is as follows:
