Problems solved by technology

In the same situation, a large amount of force is required to actuate the switch or valve, which can cause shaking of the hand and thus the suction and irrigation device
This interferes or interrupts the treatment and even increases the surgical risk, if the instrument is used with an operating microscope, as a result small movements of the instrument may lead to undesired shifts in the field of view of the microscope

Embodiment Construction

[0048] In general, in the figures, the same elements are indicated by the same reference numerals.

[0049] exist figure 1 , a first embodiment of a suction and irrigation device 1 is shown, comprising a valve body 2 with a connected proximal irrigation conduit 3, a connected proximal suction conduit 4 and a distally connected suction / irrigation Tube 5. The irrigation conduit 3, suction conduit 4 and suction / irrigation tube 5 are attached to the valve body 2 by connectors such as luer locks or similar ports. The valve body 2 is designed as a rectangular body, including large areas at the top and bottom and four sides connecting the top and bottom. The large top area is designed as an elastically deformable push surface 6 according to the invention. The distal side comprises a distally connected suction / irrigation tube 5 and the proximal side comprises a proximally connected irrigation catheter 3 and suction catheter 4 . The size of the large area and the push surface 6 are...

Abstract

A suction and irrigation device for medical use comprises a valve body with an irrigation passage and a suction passage. At least one irrigation pipe and at least one suction pipe are connectable to the irrigation passage and the suction passage by connections at a proximal side of the valve body. A suction / irrigation tube is connectable to the irrigation passage and the suction passage at a distal side of the valve body by at least one further connection. A valve assembly is provided within the valve body, which in a first position opens the suction passage and closes the irrigation passage and in a second position closes the suction passage and opens the irrigation passage. The device comprises at least one push element which interacts with at least one movable element of the valve assembly, whereas the movable element is movable by mechanical force acted upon the push element such, that the push element activates the valve assembly from one position to the other position.

Description

technical field [0001] The present invention relates to a suction and irrigation device for medical use, in particular to a hand-held suction and irrigation device operated by a person with medical training. Background technique [0002] Suction and irrigation devices are frequently used in various medical fields, for example in surgery, dentistry or general medical care. Such a device comprises a suction line and an irrigation line connected to the proximal side of the handpiece, while a tip hole is provided on the distal side, which is directed to the treatment area. An aspiration line is connected to a vacuum for drawing fluid through the tip hole, and an irrigation line is connected to a fluid reservoir for directing irrigation fluid to the treatment area through the tip hole. The handpiece may comprise an actuation unit in the form of a switch or valve for reciprocating between suction mode and irrigation mode. Many treatments require repeated back and forth between a...
