Abstract
The invention discloses a kind of human pathology or doctor's source chamber road locking devices, including sheath and push rod, push rod front end connects flexible grasp, the elasticity grasp includes the anchorage being connect with push rod front end and the multiple flexible pierce arms being connect with anchorage, and the pierce arm tail end is needle thorn portion.Elastic grasp is pressed and is placed in sheath together with push rod；Elastic grasp after being detached from sheath, open, and forms claw type grasp by pierce arm rebound.The device of the invention operation is identical as instrumentation in common cavity, has operation simple, plugging effect is good, the few advantage of residue in cavity.
Description
Technical field
The invention belongs to the field of medical instrument technology, more particularly to a kind of human pathology or doctor's source chamber road locking device.
Background technology
In puncturing operation, vascular wall can be punctured, operation finally needs to close certain pathologic or due to medical measure sheet
The cavity that body generates.Such as various atrial ventricle's wall defects；Endoscopic surgery and intravascular intervention operation established by vitro to body
Interior channel.
Current existing closing mode has：
1. the plugging device of dumbbell structure, which can form diameter more than blood vessel orifice after going deep into blood vessel with spreading
The plug of diameter, and then plug is returned and drags and can block blood vessel cavity.
2. deep stitching devices, the similar sewing principle of the device, complicated in mechanical structure is accurate, and whole operation process is cumbersome,
It needs to judge vessel position, then sutures needle, knot, trimming.
3. the methods of hemostasis gel closing.
These measure common problems have：Structure and complicated for operation, user needs to train, it is also possible to lead to cavity
There are the foreign matters of more amount to cause other complication for memory.
Invention content
In view of the above-mentioned problems, the present invention is intended to provide a kind of simple in structure, plugging effect is good, operates easy pathology or doctor
Source chamber road locking device.
The technical solution that the present invention solves the problems, such as is：A kind of human pathology or doctor's source chamber road locking device, including sheath and
Push rod, push rod front end connect flexible grasp, the elasticity grasp include the anchorage being connect with push rod front end and
The multiple flexible pierce arms being connect with anchorage, the pierce arm tail end are needle thorn portion；
Elastic grasp is pressed and is placed in sheath together with push rod；
Elastic grasp after being detached from sheath, open, and forms claw type grasp by pierce arm rebound.
To prevent from falling off elastic grasp rollback after blood vessel cut, the pierce arm outer surface is equipped with hangnail.
Specifically, there are three the pierce arm sets, it is equally spaced.
Preferably, the push rod is releasable push rod, and kickoff mechanism is equipped between push rod and anchorage.
The kickoff mechanism is electric kickoff mechanism or mechanical kickoff mechanism.
The push rod and elastic grasp are made of material absorbed by the body.
Elastic grasp pressure is held together in advance and is placed in sheath together with push rod, sheath is crossed along access needs closed chamber
Road is inserted into blood vessel；Then sheath is slowly exited, the pierce arm of elastic grasp is sprung back under natural resiliency effect opens, and forms claw type
Grasp.Later, push rod is retracted, pierce arm enters the surrounding tissue for needing to close cavity, and by group during retrogressing
It knits and comes together in anchorage.Since pierce arm has hangnail so that the device can only deeper penetrate tissue, so when tissue converges completely
Cavity closing is completed after combining in anchorage；Finally cut push rod, or if push rod per se with kickoff mechanism, releasable
And push rod is exited, complete operation.
The present invention remarkable result be：
1. device operation is identical as instrumentation in common cavity, operation is simple, and plugging effect is good.
2. device residue in cavity is only the tie point anchored, few foreign causes the risk of other complication small.
3. made of the absorbable material of specific absorption time according to the difference of destination organization, will not harmful to human it is strong
Health.

Specific implementation mode
Embodiment 1
As shown in Fig. 1~5, a kind of human pathology or doctor's source chamber road locking device, including sheath 6 and push rod 1, push rod
1 front end connects flexible grasp 2, and the elasticity grasp 2 includes the anchorage 5 and and anchorage being connect with 1 front end of push rod
Three flexible pierce arms 3 being equally spaced of 5 connections, 3 tail end of the pierce arm are needle thorn portion 31.Outside pierce arm 3
Surface is equipped with hangnail 4.
Elastic grasp 2 is held together and be placed in together in sheath 6 with push rod 1 by pressure.Elastic grasp 2 is worn after being detached from sheath 3
The thorn rebound of arm 3 is opened, and claw type grasp is formed.
The push rod 1 and elastic grasp 2 are made of material absorbed by the body.
The pressure of elastic grasp 2 is held together in advance and is placed in together in sheath 6 with push rod, sheath 6 is crossed along access to be needed to close
Cavity be inserted into blood vessel 7；Then sheath 6 is slowly exited, the pierce arm 3 of elastic grasp 2 is sprung back under natural resiliency effect opens,
Form claw type grasp.Later, push rod 1 is retracted, pierce arm 3 enters the surrounding tissue for needing to close cavity, and in retrogressing
Tissue is come together in anchorage 5 in the process.Since pierce arm 3 has hangnail 4 so that the device can only deeper penetrate tissue, institute
It is closed with working as completion cavity after tissue comes together in anchorage 5 completely；Push rod 1 is finally cut, operation is completed.
Embodiment 2
As shown in figs. 6-7, embodiment 1 is repeated, except that:The push rod 1 is set as releasable push rod, pushes away
It send and is equipped with kickoff mechanism 8 between bar 1 and anchorage 5, the kickoff mechanism 8 is electric kickoff mechanism or mechanical kickoff mechanism.
When operation, cavity closing is completed after tissue comes together in anchorage 5 completely；Push rod 1 is finally freed and exits, it is complete
At operation.
