Description
Technical field
The invention belongs to HealthCare Enterprise fields, are related to a kind of conveyer, and in particular to a kind of bracket conveyer.
Background technology
Periphery vascular surgery is the method for traditional treatment periphery hemadostewnosis, and stent in the treatment method is compared to traditional week
Side vascular surgery uses the small minimally invasive intervention operation wound of stent in the treatment, few intercurrent disease, effect good, becomes treatment week at present
The main method of side hemadostewnosis.Intravascular stent is implanted to and needs to use transport system in vivo, it is in the prior art, general to use
The hollow bowl and outer tube being mutually socketed, the hollow portion of inner tube convenient for seal wire poling when operation, intravascular stent setting in inner tube and
Between outer tube;When operation, seal wire guides the conduit tube component of transport system to reach operative site, and control assembly makes on rear side of outer tube,
Intravascular stent is unfolded and is formed in blood vessel in the process.
Due to the length limitation of intravascular stent, the structure of transport system is restricted, is not easy to existing bracket conveyer
The surgical procedure of medical staff, needs both hands to operate, and is also easy to produce in the transmission process of longer conveying stroke and trembles and deviate, defeated
Send it is unstable, severe patient can even make intravascular stent generate offset, influence the normal progression of operation.Transport system was conveying
Pause conveying operations occur for Cheng Zhonghui, and operating personnel is needed to grip transport system at this time, extremely inconvenient, and defeated in the prior art
Send system that there is two-stage pause button, but in performing the operation, pausing operation may occur at any time, and two-stage pause button, which cannot be satisfied, to be needed
It asks.Intravascular stent in transmission process there are certain resistance, and transport system delivery device there is also certain frictions
Power causes transport system to need larger push power, is not easy to medical staff's operation, and push intensity is larger, and due to pushing power
It is larger, easily lead to intravascular stent conveying it is unstable, there are the situations such as tremble and deviate, severe patient can even be such that intravascular stent generates
Deviation influences the normal progression of operation.
Invention content
A kind of bracket conveyer is provided the invention aims to overcome the deficiencies in the prior art.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of bracket conveyer, it includes shell, installation
Trigger on the housing, in the shell and one end extends to centre pipe outside the shell and slidably
Ground is sheathed on the outer sheath on the centre pipe, it further include be mounted in the shell and respectively with the trigger and described
The transmission mechanism that outer sheath is connected, the transmission mechanism include the transmission gear being connected with the centre pipe surface and institute
State transmission gear be meshed and the rack being connected with the trigger and one end be connected with the trigger for make its reset
Elastic component.
Optimally, one end of the centre pipe is equipped with the end outside the outer sheath.
Optimally, the guide rod for being used to support positioned at the outer sheath both sides is fixed in the shell.
Further, it further includes being slidably mounted on the shell for limiting the outer sheath and the center
The sliding block of conduit sliding, the sliding block are slideably sheathed on the guide rod.
Optimally, one end of the rack is connect with the trigger phase pivot.
Further, it further includes being sheathed on outside the outer sheath to slide for limiting the outer sheath and the centre pipe
Dynamic limited block, the limited block extend partially into outside the shell.
Optimally, the shell includes handle portion and the straight sections with handle portion one.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：Holder conveying of the present invention
Device, by installing the transmission mechanism being connected with trigger and centre pipe in shell, which includes rack, driving cog
Wheel and elastic component, can avoid conveyer from being generated in longer conveying stroke and tremble and deviate, and be easy to control conveying in this way
Start and stop, the conveying that accurately controls centre pipe formed, it is ensured that the safety of operation carries out.

Specific implementation mode
Below in conjunction with attached drawing embodiment, invention is further explained.
Embodiment 1
Below in relation in the definition in direction, being that direction observed when holding the bracket conveyer according to user is given
With definition.
Bracket conveyer as depicted in figs. 1 and 2, mainly include shell 1, trigger 2, transmission mechanism 3, outer sheath 6 and in
Cardiac catheter 7 etc..
Wherein, shell 1 includes straight sections 11 and handle portion 12, they can be arranged as needed integral or can
Dismounting；In addition, shell 1 can be arranged to be made of symmetrical two parts, they can be disassembled in actual use person
To replace the parts of damage.Trigger 2 is mounted on shell 1, only needs to press i.e. it when using bracket conveyer
It can.The part of centre pipe 7 is located in shell 1, its rear end is fixed or on shell 1（Shell 1 can also be extended to
Outside）, its front end then extends to outside shell 1.Outer sheath 6 is then slidably sleeved on centre pipe 7, and transmission mechanism 3 is then pacified
It is connected in shell 1 and with trigger 2 and outer sheath 6 respectively.Transmission mechanism 3 includes rack 31, transmission gear 32 and elasticity
Part 33；Transmission gear 32 is connected with 7 surface of centre pipe, and connection type here can be engagement, can also be to have friction
The surface of power contacts；Rack 31 is meshed with transmission gear 32, and its one end is connected with trigger 2；One end of elastic component 33
It is connected with trigger 2, the other end is usually fixed with 1 phase of shell, for making trigger 2 reset, and then being capable of answering with carry-over bar 31
Position；Spring is used in the present embodiment.The operation principle of bracket conveyer is：When in use, driver is driven by trigger squeeze 2
Structure 3 moves, and then drives outer sheath 6 to be slided with respect to centre pipe 7 by the transmission mechanism 3 for contacting or engaging with 6 surface of outer sheath
It is dynamic so that the holder being placed between centre pipe 7 and outer sheath 6 is released.
In the present embodiment, the front end of centre pipe 7 is equipped with the end 8 outside outer sheath 6, to guarantee in blood
Centre pipe 7 is smoothly pushed in pipe forward.It is fixed with each guide rod 4 positioned at 6 both sides of outer sheath in shell 1, plays support
The effect of outer sheath 6.Sliding block 5 is slidably mounted on shell 1, it is also slidably sleeved on guide rod 4, by using existing
Some structures can be realized applies active force to the surface of outer sheath 6；Since outer sheath 6 is toughness, when there is active force application
At its surface, frictional force between outer sheath 6 and centre pipe 7 increases and plays the role of limiting and slide between them.
