Description
Technical field
The present invention relates to medical operating ancillary technique field, especially a kind of anterior chamber's isolating device.
Background technology
Clinically widely applied cataract operation mode is mainly phacoemulsification cataract surgery in China.Ultrasonic emulsification
Corneal endothelium can cause different degrees of damage when crystal nuclear, keep cataract cure rate low, and bigger is brought to patient
Pain.Past doctor air or balanced salt solution maintain anterior segment surgery space, but the protective effect of its corneal Endothelium is very
It is weak.
At present before carrying out phacoemulsification cataract surgery it should be understood that the endothelial cell situation of patient, if
Corneal endothelium density is low, cannot carry out the operation, prevent patient from timely and effectively being treated.Later, viscoelastic agent became super
Ideal adjuvant in sound phacoemulsification, although viscoelastic agent is comparatively ideal adjuvant in phacoemulsification cataract surgery,
Many adverse reactions are brought to patient's cornea and its adjacent tissue.For example, in use due to clear up it is unclean, itself at
Point and the reasons such as molecular structure also result in that corneal endothelium protection is insufficient and corneal damage etc..

It sets, is used to assist cataract operation, with passability is good, surgical procedure is simple, surgical wound is small, reduces operation risk, no
The advantage of meeting corneal damage.
To achieve the above object, the technical solution that the present invention takes is：A kind of anterior chamber's isolating device, including sacculus, push
Bar, T connectors, seal wire, seal wire handle and gas-charging connection, the sacculus and push rod are integrally formed, and the push rod is hollow knot
Structure, described push rod one end are connect with the first interface of the T connectors, and the relatively described sacculus edge of the push rod other end is prominent
Go out, the T connector second interface opposite with the T connectors first interface has a seal wire handle in succession, and the seal wire is through institute
It states in push rod, one end of the seal wire is connect with the seal wire handle, the third connector among the T connectors and the inflation
Connector connects.Wherein, on the one hand the main function of seal wire is to facilitate surgical operation, is on the other hand conducive to consolidating for sacculus
It is fixed.
As advanced optimizing for said program, the balloon diameter is 8~9mm, and the thickness after the inflated is
0.5~1.5mm.Thickness after inflated is preferably 1mm.
As advanced optimizing for said program, the side of the sacculus is arc, preferably semicircle.Operation is given as a result,
Reserve more spaces in area.
As advanced optimizing for said program, the push rod passes through the center of the sacculus.It is convenient for accurate adjust as a result,
Save the position of sacculus.
As advanced optimizing for said program, the seal wire handle and the T connectors are equipped with corresponding label；More
Further, it is respectively equipped with two lines section on the seal wire handle and the T connectors, the two lines section is mutually parallel and is located at
On same plane.The opening direction that can indicate sacculus by label as a result, convenient for adjusting sacculus by seal wire handle in time
Position.
As advanced optimizing for said program, the sacculus is folded using the push rod as axis.Work as ball as a result,
When capsule folds, convenient for passing through from smaller surgical wound, operation risk is reduced.
As advanced optimizing for said program, gap is equipped between the seal wire and push rod.Gas or liquid as a result,
Reach sacculus through gap, with dilatation balloon to the state of suitable operation.Wherein, seal wire is made of stainless steel.
As advanced optimizing for said program, the seal wire is hollow, and the seal wire is equipped with multiple apertures.As a result,
The efficiency of sacculus ventilation and deflation can be improved by aperture, shorten operating time.
In conclusion beneficial effects of the present invention are：
Push rod and sacculus are integral type hollow structure in anterior chamber's isolating device of the application, and there is seal wire in inside, facilitates ball
Capsule is fixed, and sacculus is finally folded by axis of push rod, and seal wire handle can adjust the open position of sacculus in time, and gas-charging connection can
To be conveniently adjusted the inflated condition of sacculus, make in surgical procedure passability is good, surgical procedure is simple, surgical wound is small, reduce
Operation risk.
