Description

Detachable sinus forceps

Technical field

This utility model relates to a kind of nose ethmoid forceps, especially a kind of detachable sinus forceps.

Background technology

The nose ethmoid forceps is a kind of operating theater instruments commonly used in the intranasal videoendoscopic surgery.Because the particularity of nasal cavity, general nose ethmoid forceps structure is all very complicated, and in order to keep the stable use of medical apparatus and instruments, existing nose ethmoid forceps all can't be dismantled.

In the nose ethmoid operation, the nose ethmoid forceps often often need to touch blood stains, and blood stains are easy to preserve in the slit of nose ethmoid forceps, can not often can't clear up completely by entirely disassembled nose ethmoid forceps.These remaining blood stains arch-criminal of cross infection in the nose ethmoid operation just.And in the slit, accumulate more pollutant, and tend to shorten the cycle that the nose ethmoid forceps gets rusty, shorten the service life of nose ethmoid forceps.

The utility model content

The technical problems to be solved in the utility model provides a kind of detachable sinus forceps that can dismantle at any time.

In order to solve the problems of the technologies described above, this utility model provides a kind of detachable sinus forceps, comprises front clamp handle, rear clamp handle, upper push-rod, moving binding clip and decides binding clip; Arrange on the described lower push-rod and decide binding clip, lower push-rod and moving binding clip are rotationally connected; Upper push-rod and moving binding clip are rotationally connected; Described lower push-rod is fixedly connected with rear clamp handle, is provided with the clamp handle jack on the lower push-rod, and the clamp handle jack runs through lower push-rod; All have the U-shaped draw-in groove that Open Side Down in the two sides of clamp handle jack; Be provided with circular dop on the front clamp handle, on dop, correspond to the U-shaped draw-in groove and be provided with the clamp handle pivot pin; On upper push-rod, correspond to dop and be provided with the C shape draw-in groove that Open Side Down, in a side of C shape draw-in groove, be provided with the U-shaped draw-in groove entrance that Open Side Down; Described dop passes the clamp handle jack, behind U-shaped draw-in groove entrance, snaps in the C shape draw-in groove; Described clamp handle pivot pin is stuck on two U-shaped draw-in grooves.

As the improvement to detachable sinus forceps of the present utility model: be provided with front finger circle on the front clamp handle, be provided with rear finger circle on the rear clamp handle.

Detachable sinus forceps of the present utility model, dop snaps in C shape draw-in groove after by U-shaped draw-in groove entrance, and U-shaped draw-in groove entrance is opening down, if with U-shaped draw-in groove entrance break off with the fingers and thumb dop directly over the time, just upper push-rod can be separated with dop, and the clamp handle pivot pin is stuck in the U-shaped draw-in groove that Open Side Down, when dop separates with upper push-rod, just can very easily the clamp handle pivot pin be taken out in the U-shaped draw-in groove.

This detachable sinus forceps that can be for convenience detach can be dismantled and come complete cleaning once after using each time, prevents from remaining in the blood stains corrosion nose ethmoid forceps in the nose ethmoid forceps, prolongs the service life of nose ethmoid forceps; And guarantee that when using real the keeping clean of nose ethmoid forceps energy prevents the generation of cross infection next time.
