Description
The other abdominal cavity mouse of bed.
Technical field
The present invention relates to the mouse used in a kind of medicine equipment, more particularly to a kind of endoscope-assistant surgery.
Background technology
Stamp card（Trocar）Also known as trochar or paracentesis trocar.Trochar is widely used in thoracentesis
In, its specific method：With the trochar of PCI, during puncture, sleeve pipe is needled into pleural cavity, puncture needle is extracted, makes
Sleeve pipe is stayed in pleural cavity, is then operated through sleeve pipe injection or drainage etc..Its advantage is, after puncture needle enters pleural cavity, set
Pipe, which stays in, can large range of movement in pleural cavity.It is particularly suitable for that hydrothorax is few, position is low, near from internal organs such as shy flesh, livers
Patient.But trochar of the prior art still has the disadvantages that：1）Due to being punctured using existing puncture cannula
Afterwards, trochar front end has tunnel vision, and hysteroscope can not be coordinated to establish hysteroscope passage and inspection, therefore cannot pass through existing sleeve pipe
Pin carries out abdominal cavity Peep Technology by bed；2）After puncture cannula is pierced into vivo, puncture cannula displacement may cause puncture cannula to damage
Deep tissue or puncture cannula abjection body cavity, therefore prevent that puncture cannula from shifting or fixed puncture cannula is each puncture cannula
Technical problems to be solved, and existing fixed puncture cannula method is the friction using increase puncture cannula and tissue of perforating
The mode of power, for example add a few screw threads in puncture cannula external diameter or form mat surface, but use this of increase frictional force
Although kind of a mode can play fixed effect, damage of the puncture cannula to surrounding tissue is added simultaneously；3）Due to puncturing
When need to carrying out ventilation supercharging in vivo, and existing fixed form due to use is all that localized contact is fixed so that pressure
Gas easily enters at unsealing subcutaneously causes pneumoderm, so as to cause secondary injury to patient.
The Chinese utility model patent of Application No. 201420440838.8 discloses a kind of automatic stationary type puncture cannula,
It is characterized in that：The puncture cannula outer cover is equipped with an air bag, and the air bag is provided with air inlet, and the air bag is not when working
For hollow cylinder, the length of the air bag is more than the thickness of site of puncture tissue so that the both ends of air bag are set when air bag works
Put outer in tissue.It is strictly a relatively good method to grappling puncture cannula using air bag, however, automatic in the patent
Fixed puncture cannula runs into following technical problem in actual use：1）The frictional force of balloon surface causes paracentesis trocar to exist
Certain resistance and frictional force are produced when being deep into organization internal, or even is difficult to insert, equally causes puncture cannula to surrounding group
The damage knitted；2）The air inlet of air bag is set can not be inflated at all in vivo, but air inlet is set in vitro then
Need to be separately provided gas tube and aerating device so that the operation of trochar becomes sufficiently complex, also increases be manufactured into addition
This；3）Can not solve to establish hysteroscope and the technical problem of drainage channel simultaneously.
The content of the invention
In view of this, it is an object of the invention to provide abdominal cavity mouse by a kind of bed, the other abdominal cavity mouse of this bed can be effective
Ground fixed jacket pipe, outer tube damage deep tissue caused by avoiding outer tube displacement possibility or outer tube abjection body cavity
Problem, while by improving the structure of air bag so that the stamp card can coordinate abdominal cavity by sight glass operation completion bed to spy on skill
Art.
The present invention solves above-mentioned technical problem by following technological means：
Abdominal cavity mouse by the bed of the present invention, mainly including outer tube, the air bag being fixedly installed on above outer tube, fixation
The casing seat, nook closing member and the needle stand for being fixedly installed on nook closing member tail end of outer tube tail end are arranged on, the outer tube is set in nook closing member
On, described sleeve pipe seat, hysteroscope passage is provided with described sleeve pipe seat, the outer tube is provided with inflation close to the opening position of tail end
Joint, the filling channel for connecting the gas-charging connection and air bag is provided with the outer tube.
Further, the longitudinal section of the air bag is the c-type structure of internal cavities, and the air bag is arranged on outer tube front end,
End spaces before outer tube is surrounded by the c-type structure of air bag, and the hole for allowing nook closing member to pass through is provided with the middle part of the air bag.
Further, the outer tube includes inner tube sheath and the outer tube sheath that is set on the outside of inner tube sheath, and the two of said inner tube sheath
End is stretched out from the both ends of outer tube sheath respectively, and the air bag is connected with the front end of inner tube sheath and the forward end seal of outer tube sheath respectively.
Further, the external diameter of the outer tube is 3-5mm.
Further, the gas-charging connection is mainly made up of pressure bladder and the joint being arranged on above pressure bladder, described
Pressure bladder one end is set in the tail end of outer tube sheath, and is fixedly connected with the tail end sealing of outer tube sheath, the pressure bladder it is another
One end casing seat is tightly connected, and the nook closing member passes through inside pressure bladder, and the outer tube sheath is slidably matched with nook closing member.
The invention has the advantages that：Abdominal cavity mouse by the bed of the present invention, by setting air bag on outer tube
Setting not only effectively fixed jacket pipe, avoid outer tube displacement may caused by outer tube damage deep tissue or outer
Sleeve pipe deviates from the problem of body cavity, while air bag is arranged on to the front end of outer tube, can effectively be opened up under inflated condition
The visual field of wide sight glass so that abdominal cavity Peep Technology by bed can be carried out by the stamp card.
