Description

Collar taking-out device for medical breaking instrument Technical Field The invention relates to the technical field of medical instruments, in particular to a collar taking-out device of a medical breaking instrument. Background In the medical field, such as orthopaedics, maxillofacial surgery and dental socket surgery, bone removal is often required by using a drill, dental department needs to use a file needle for root canal preparation, and due to reasons of improper use, fatigue of instruments and the like, the drill is broken in bone occasionally, and the file needle is broken in the root canal. Clinically, the breaking devices are locked in a narrow cavity space, and the common clamp forceps cannot be taken out and need to be taken out by using special devices. Aiming at the problem, the existing breaking instrument extraction devices are mainly divided into three types, namely a sleeve-cone, a lasso and a micro clamp. The sleeve-awl scheme needs to prepare a series of sleeves and awls with different thicknesses for the breaking instrument with the thickness of the pen container, and the sleeve can block the vision when the breaking instrument is taken by the instrument due to the fact that the sleeve needs to be aligned with the breaking instrument. The micro-clamp scheme is not suitable for taking a break instrument with relatively tight clamping due to the fact that the clamping heads of the clamp are very small and the clamping force is limited. The prior art 'lasso' (or lantern ring) technical scheme, for example, chinese patent application publication No. CN115105230A discloses a lantern ring system for taking out a combined type intraductal breaking instrument, which comprises an outer sleeve, wherein a lasso pipe assembly with part extending out of the outer sleeve is arranged in the outer sleeve, the lasso pipe assembly comprises a sleeve and a filiform lasso arranged at one end extending out of the sleeve to form a lantern ring, an adjustable installation assembly for installing the lasso pipe assembly is arranged in the outer sleeve, a pushing conduction block which is matched with the adjustable installation assembly to push the sleeve to move so as to adjust the size of the lantern ring is arranged in the outer sleeve, and a handheld power assembly which is detachably connected with the outer sleeve and provides thrust for the pushing conduction block is arranged outside the outer sleeve. The lasso-type prior art has the advantages of good operation visual field and large clamping force, but has the problems of complex device structure, inconvenient installation of lasso wires and inconvenient operation when tightening the lantern ring. Disclosure of Invention The invention provides a medical breaking instrument taking-out collar device, which aims to solve the technical problems of complex structure and inconvenient operation of a breaking instrument taking-out device in the prior art.
