Description
Technical field
The present invention relates to a kind of stenter to implant devices of medical instruments field more particularly to a kind of band to load supporting structure
Implanted device.
Background technique
Interventional therapy is one and has merged the new branch of science that diagnostic imaging and clinical treatment are integrated, since it is in image
Equipment will be intervened by human body natural duct or small wound under equipment guidance and import body foci's progress minimally-invasive treatment, therefore
Have many advantages, such as that accurate, safe and efficient, wide indications, few intercurrent disease, wound are small, post-operative recovery is rapid, has become some diseases
The preferred treatment method of disease, and become the clinic three big pillar subject one of arranged side by side with traditional Medicine and Surgery.Common implanting device
Into body cavities corner, corner can not be continued through, operation risk is caused to increase or operative failure.
Therefore, the urgent need to resolve above problem.
Summary of the invention
Goal of the invention: the object of the present invention is to provide one kind can repeatedly be implanted into multiple brackets, keeps operation smoothly safe
The implanted device with filling supporting structure efficiently carried out.
Technical solution: in order to achieve the above object, the invention discloses the implanted devices that a kind of band loads supporting structure, including
The inner and outer tubes being mutually arranged, said inner tube inner cavity are equipped with push rod, and the distal end of the outer tube is connected with soft head, the outer tube
Distal lumen is compressed with first support, and distal end of the both ends of the first support respectively with the proximal end of soft head and push rod abuts against；It pushes away
Dynamic push rod drives first support Forward, so that first support discharges out of outer tube and restores reset condition；The outer wall of the outer tube
It is arranged with filling bracket component, the bracket component that loads includes the pipe that lower half section of jurisdiction by mutually fastening and upper half section of jurisdiction form
It saves, spare bracket can be pre-installed in the tube coupling；The notch communicated with tube coupling is accordingly offered in said inner tube and outer tube.Band of the present invention
Load supporting structure implanted device pushes first push rod drive first support Forward so that first support out of outer tube with soft head
Distal end discharges and restores reset condition；After first support releases, push rod is withdrawn, opens simultaneously upper half section of jurisdiction, by spare branch
Frame is placed in tube coupling, pushes push rod, and spare bracket is pushed into replace first support in the distal cavities of outer tube, repeats release the
The movement of one bracket can discharge spare bracket again, repeatedly, can repeatedly be implanted into multiple brackets, pacify operation can smoothly
Complete efficient progress.
Wherein, the proximal outer tube outer wall is arranged with handle.
Preferably, the distal end inner wall of said inner tube is equipped with stop block.
Furthermore it is equipped in the upper half section of jurisdiction and matches with the notch in inner tube, the filling pipe for pre-installing spare bracket
Piece.
Further, the upper half section of jurisdiction matches with the notch on outer tube.
Preferably, the soft head is hollow structure, is communicated with outer tube bore.
The utility model has the advantages that compared with prior art, the present invention has following remarkable advantage: the present invention can repeatedly discharge multiple
Frame greatly shortens bracket release operating time, reduces patient due to repeatedly passing in and out implanting device bring pain and infecting
Probability, and implanted device cost is saved, improve operational safety.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram that bracket component is loaded in the present invention.
Specific embodiment
Technical solution of the present invention is described further with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of band of the present invention loads the implanted device of supporting structure, including inner tube 1, outer tube 2, pushes away
Bar 3, first support 5, loads bracket component 6, spare bracket 7 and handle 8 at soft head 4.1 outer tube 2 of inner tube is mutually arranged, inner tube 1
Inner cavity is equipped with push rod 3.2 distal end of outer tube is connected with soft head 4, and soft head 4 is hollow structure, communicates with 2 inner cavity of outer tube.Outer tube 2 is remote
End inner cavity is compressed with first support 5, which abuts against with soft 4 proximal end of head and 3 distal end of push rod respectively；Promotion pushes away
Bar 3 drives first support 5 to move forward, so that first support 5 discharges out of outer tube 2 and restores reset condition.2 proximal end outer wall set of outer tube
Equipped with handle 8.The outer wall of outer tube 2, which is arranged with, loads bracket component 6, and loading bracket component 6 includes the lower tube half by mutually fastening
The tube coupling that piece 601 and upper half section of jurisdiction 602 form can pre-install spare bracket 7 in the tube coupling；It is accordingly offered on inner tube 1 and outer tube 2
The notch communicated with tube coupling.It is equipped in upper half section of jurisdiction 602 and matches, with the notch in inner tube 1 for pre-installing filling out for spare bracket
Tubulature piece 603.Upper half section of jurisdiction 602 matches with the notch on outer tube 2.The distal end inner wall of inner tube 1 is equipped with stop block 101, can stop
Keep off first support 5.
The material of outer tube of the invention is polytetrafluoroethylene material；Length can according to for breathing, the difference of alimentary canal etc.
It needs and processes different preferred lengths.The effect of outer tube is that collaboration is soft first with body cavities are passed through, to make other instruments
Or component passes through required position.Inner tube of the invention is to be sent to human body natural's cavity for releasing the bracket in outer tube
Diseased region.The effect of handle is operator's handgrip part during implanting device enters body cavities.
The implanted device that band of the present invention loads supporting structure pushes push rod to drive first support Forward first, so that first
Frame discharges with soft head distal end out of outer tube and restores reset condition；After first support releases, push rod is withdrawn, is opened simultaneously
Spare bracket is placed in tube coupling by half section of jurisdiction, pushes push rod, and spare bracket is pushed into replace first in the distal cavities of outer tube
Bracket repeats the movement for discharging first support, can discharge spare bracket again, repeatedly, can repeatedly be implanted into multiple brackets, make
Operation smoothly can be carried out safely and efficiently.
