Hydrops box for ultrasonic emulsification operation

Abstract

The invention discloses a hydrops box for an ultrasonic emulsification operation. The hydrops box comprises a box body composed of a front plate, a main body and a rear plate, the box body is communicated with a waste liquid bag; the main body is provided with a perfusion passage and a suction passage which are independently arranged; the filling passage is a sealed circulation cavity jointly defined by the cover body and the main body; the circulation cavity is communicated with a first connector and a second connector on the main body for perfusion, a gap exists between the cover body and the main body, and the cover body is extruded to control the connection and disconnection of the perfusion passage; the suction channel is a pipeline which is communicated with the third connector and the waste liquid bag and conducts suction through a peristaltic pump, and the suction channel is further communicated with a negative pressure adjusting loop so as to adjust the pressure in the suction channel. The perfusion channel and the suction channel are independently arranged, so that the perfusion channel and the suction channel do not interfere with each other and work independently; meanwhile, it is guaranteed that the pressure in the perfusion channel is stable, changes of intraocular pressure are reduced, and use safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an effusion box used for phacoemulsification. Background technique [0002] Clouding of the lens or cataracts are fairly common as we age. Cataracts can be treated by replacing the cloudy lens with an intraocular lens. Ophthalmic phacoemulsification surgery is the most advanced cataract treatment technology. The phacoemulsification system usually uses ultrasonic energy to break the lens and suction the lens from the capsular bag. [0003] Precise control of fluid volume and intraocular pressure in the eye is important during cataract surgery and other treatments of the eye. While ultrasonic energy can fragment the cataract and allow it to be drawn into the treatment probe with suction, a corresponding irrigation fluid needs to be introduced into the eye so that the total volume of fluid in the eye does not change excessively. If the total volume of fluid in the eye ...

AI Technical Summary

Problems solved by technology

[0004] During the operation, when the cataract at the needle is suddenly sucked away, a surge often occurs, which can cause rapid changes in intraocular pressure, which can easily cause damage to the eye

[0005] In the existing ophthalmic surgery system, a surgical box that can cooperate with the host is usually used to realize the perfusion and suction functions, but the existing technology usually uses the form of gravity perfusion to realize the perfusion function, and the perfusion pressure cannot be detected in real time; and the existing When a surge occurs, the technology often uses the fluid from the perfusion channel to flow into the suction channel. This method will cause instability of perfusion pressure and aggravate changes in intraocular pressure.
