Description
Technical field
The present invention relates to minimally invasive medical instrument field, especially a kind of rapid exchange stent imbedding system.
Background technique
Last century the seventies are traced back to, at that time, for the jaundice that Malignent Biliary Obstruction causes, alleviation method still has very much
Limit.The morbidity and mortality of biliary tract Bypass Surgery are high, and percutaneous liver drainage operation causes pain and bile to be lost, extremely
It is also very high to die rate.In the seventies later period, the appearance of biliary tract rack Intra drainage is placed under scope, is the mirror of Malignent Biliary Obstruction
Lower treatment brings breakthrough progress.
Relative to Endoscopic nasobiliary drainage, the merging of bile duct inner drainage tube will eliminate patient's oropharynx and nasal cavity not
The shortcomings that fitting, overcoming the loss of body fluid caused by nasobiliary drainage, acid-base imbalance and water and rock-soil coupling, it is also unlikely
In the feed and instrument that influence patient.But it can not observe the drainage situation of bile after being placed in, can not be rinsed, into
Synthesis, adequately assessment should be carried out when row therapeutic choice.
Since Minimally Invasive Surgery does not have to operate on, wound is small, and operating time is short, and complication is few compared with surgical operation, the hospital stays
It greatly shortens, it is deep to be welcome by patient.Huge achievement is clinically achieved in short decades, has become current pancreas gallbladder disease
The seriously ill treatment means wanted, the market demand are also increasing.
Plastic stent imbedding system currently used in the market is essentially all conventional structure, using 4.5m long seal wire into
Row guide instrument, it is inconvenient in change of equipment.In order to make medical staff more convenient using instrument, exchange more rapidly, from
And reduce operating time, cause less pain to patient, provide can fast exchange medical instrument and method increasingly have must
It wants.
A kind of mainstream fast exchange scheme is that a slope is arranged in guiding tube portion to export, and seal wire enters from inner spout, meets
It exports out to guide pipe slope, since it needs to accomplish inner tube completely into bracket is discharged in guide pipe, inner tube needs again
The bracket of its releasable longest specification is wanted, therefore the outlet of its slope needs the length at least more than inner tube apart from guide pipe far distance port
(its inner tube assembly is made of one piece of steel wire of one section of inner tube and push), then seal wire is drawn from its system, is needed in its system
Very long a distance is inside occupied, seal wire, then there may be the defect of curtailment, will be unfavorable for medical care after the introducing of its support system
Personnel's operation.
It only punches the shortcomings that directly leading out scheme (COOK) of seal wire on inner pipe currently on the market to be, only on inner pipe
Punching, after bracket imbedding system is introduced human body by seal wire, due to the obstruction of seal wire, inner tube cannot be introduced into guide pipe, then bracket
It can not discharge, it is therefore necessary to first take out seal wire from system, just releasable bracket, such support system loses seal wire guidance, then
Bracket releasing position loses accuracy.
Summary of the invention
The purpose of the present invention is to provide a kind of bracket imbedding systems of fast exchange, to realize the mesh of fast exchange instrument
's.
The technical scheme is that
A kind of rapid exchange stent imbedding system, the bracket imbedding system (10) include seal wire (2), inner tube (3), plastics
Bracket (4), guide part, developing ring (7), guiding outer tube (8), front hand grip (15), Handleset (16), boost tube (17) and defensive position
Handle (18), seal wire (2) setting are oriented to outer tube (8) proximal end and front hand grip (15) are fixed together, inner tube (3) is close in inner tube (3)
End is fixed on back handle (18) by boost tube (17), and developing ring (7) is fixed on inner tube (3), and guide part is mounted on inner tube
(3) on, the slit (20) of the release stent length enough of guiding outer tube (8) setting one, inner tube (3) installs guide part, guide part limit
Position is placed in slit (20), and inner tube (3) is opened a side opening (3a), and seal wire (2) is inserted into from inner tube (3) front end, encounter guide part from
Inner tube (3) is drawn, and by pulling back handle (18) that inner tube (3) is driven to make inner tube (3) completely into guiding outer tube (8), is then moulded
Expect that bracket (4) are i.e. releasable, while seal wire (2) can be along slit (20) activity of guiding outer tube (8), thus real on inner tube (3)
The fast exchange function of existing instrument.
The seal wire (2) is fast exchange 2.6m short-length guidewires.
Side opening (3a) setting of said inner tube (3) is in distally close guiding outer tube (8) distal end endface position, and side opening
The opening direction of (3a) and slit (20) are consistent.
Distal face of slit (20) initial position apart from guide pipe (8) retains a distance.
The guide part is first scheme guide part (5), and first scheme guide part (5) is mounted on inner tube (3) by proximal aperture
At (3a), the front end of first scheme guide part (5) has an arc surface (5a), and the rear end of first scheme guide part (5) has
One guide protrusions (5b)；Wherein: the guide protrusions (5b) of first scheme guide part (5) are placed in slit (20)；] seal wire
(2) be inserted into side opening (3a) from inner tube (3) front end, seal wire (2) encounter the guide part arc surface (5a) of first scheme guide part (5) from
Inner tube (3) is drawn, and by pulling back handle (18) that inner tube (3) is driven to make inner tube (3) completely into guiding outer tube (8), is then moulded
Expect that bracket (4) are i.e. releasable；Seal wire (2) can be along slit (20) activity of guiding outer tube (8), thus real on inner tube (3) simultaneously
The fast exchange function of existing instrument.
The guide part is alternative plan guide part (35), and alternative plan guide part (35) includes the guiding with arc surface
Head (35a) and guide and limit body (35b)；The guide head (35a) of alternative plan guide part (35) is mounted in inner tube (3)；Second
The guide and limit body (35b) of scheme guide part (35) is placed in slit (20), and guide and limit body (35b) is T-type, T-type top
Part is wider than the width of slit (20), it is ensured that alternative plan guide part (35) will not because of guide pipe (8) distortion and lose
Guiding role；Seal wire (2) is inserted into from inner tube (3) front end, is encountered after the guide head (35a) of alternative plan guide part (35) from inner tube
(3) it draws, pulls back handle (18) that inner tube (3) is driven to keep inner tube (3) interior completely into guiding outer tube (8), then plastic stent (4)
It is i.e. releasable；Slit (20) of the seal wire (2) on inner tube (3) along guiding outer tube (8) is movable simultaneously, to realize the quick of instrument
Function of exchange.
The guide part is third program guide part comprising two independent components, it is respectively only with arc surface
Vertical guide head (44) and independent pilot tail (45), independent pilot tail (45) are equipped with protuberance component (46), independent pilot head (44)
It being mounted in inner tube (3) with independent pilot tail (45), the protuberance component (46) of independent pilot tail (45) is placed in slit (20),
Inner tube (3) is opened a side opening (3a), and seal wire (2) is inserted into from inner tube (3) front end, is drawn after encountering independent pilot head (44) from inner tube (3)
Out, inner tube (3) are driven to keep inner tube (3) interior completely into guiding outer tube (8) by pulling back handle (18), then plastic stent (4)
It is i.e. releasable, while seal wire (2) can be along slit (20) activity of guiding outer tube (8), to realize the fast of instrument on inner tube (3)
Fast function of exchange.
The beneficial effects of the present invention are:
The present invention compared with the prior art for, do not need first to extract seal wire out when Stent Implantation, seal wire can be still
It is maintained at the position of medical staff's needs.The present invention because of the position of slit and apart from adjustable, seal wire only need very short one section away from
From that can draw from system, then the above problem is not present.
