Description

The safety block structure of tube type anastomat

Technical field

This utility model relates to a kind of safety block structure of tube type anastomat, belongs to medical instruments field.

Background technology

At present, it is loosening automatically that safety block can take place when the needs safety position or during release conditions the safety block of the tube type anastomat under the prior art, causes safety block to break away from safety position or off-position, thereby make safety block lose the effect of insurance.

Summary of the invention

The purpose of this utility model is the deficiency that overcomes prior art, provide a kind of when needing safety position or during release conditions safety block all can not become flexible the safety block structure of the tube type anastomat that breaks away from automatically.

The technical scheme that realizes this utility model purpose is: a kind of safety block structure of tube type anastomat; It comprises safety block, first handle and second handle; First handle is fixedly connected with second handle; Safety block is hinged on first handle and the second handle, and described safety block is provided with positioning boss and elastic groove, has the release conditions locating hole and the safety position locating hole that cooperate with positioning boss on the second handle.

After having adopted technique scheme; Because the positioning boss of safety block is stuck in the safety position locating hole of second handle when safety position; The positioning boss of safety block is stuck in the release conditions locating hole of second handle when release conditions; Add the effect of elastic groove, make positioning boss can not throw off safety position locating hole and release conditions locating hole easily, so just make safety block bring into play the effect of insurance.
