Abstract
A general type equipment for taking out intramedullary nails includes an expansion head, a expansion wire cylinder, a fastening nut, a screw, a fixation element, a handle and a suspension element. The handle is a main body element provided integrally with a cylinder shape, and the outside of the handle is provided with a concavo-convex shape convenient to be held by hand. The suspension element is disposed at the rear terminal of the handle, a screw is disposed at the front terminal of the handle, the expansion head is disposed at the front terminal of the screw, and the expansion wire cylinder is disposed on the screw behind the expansion head. The expansion wire cylinder is a sleeve cylinder connected with the screw through a cup joint. Pressed worms are provided on the outside of the expansion wire cylinder, three or four slots are provided at the front terminal of the expansion cylinder, and the fastening nut is disposed on the screw behind the expansion cylinder. The fixation element with the same profile as the fastening nut to facilitate fixation and operation is disposed at the rear part of the screw. The disclosed equipment has a general use for taking out diversified intramedullary nails to avoid disturbance and fuss caused by intramedullary nails of incorrespondent models and also avoid patients' pain caused by that intramedullary nails can't be taken out in time.
Description
Technical field:
This utility model relates to shell operation auxiliary device, relates in particular to the general-purpose type intramedullary nail extractor.
Background technology:
The intramedullary nail extractor of prior art is to be the supporting product of product of different model separately, and is not general mutually, so in the practical operation that intramedullary pin takes out, the normal difficult situation that can not find supporting extractor causes difficulty for the doctor of operation, causes suffering also for relevant patient.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of general-purpose type intramedullary nail extractor is provided, to adapt to the needs that various intramedullary pins take out.
General-purpose type intramedullary nail extractor described in the utility model, including expansion-head, expansion wire cylinder, clamp nut, screw rod, fixture, handle and hanging part forms, handle is the main component of general-purpose type intramedullary nail extractor described in the utility model, handle integral body is cylindrical, and it is concavo-convex that the outside is set to be convenient to hand.The rear end of handle is provided with hanging part, and said hanging part is identical with the hanging part of prior art.The front end of handle is provided with screw rod, and the front end of screw rod is provided with expansion-head, on expansion-head screw rod backward, is provided with expansion wire cylinder.Said expansion wire cylinder is a sleeve that is socketed on the screw rod, and telescopic outside is compressed to screw-like, and telescopic front end is provided with 3 to 4 roads and cracks, and adopts the principle and the structure of expansion bolt.On the screw rod of expansion wire cylinder rear end, be provided with clamp nut.Tighten clamp nut for convenience, be provided with fixture, adopt the profile form identical, with convenient fixing and operation with clamp nut at the rear portion of screw rod.During concrete operations, can control fixture with spanner, just controlled screw rod, block clamp nut with the another spanner, tighten clamp nut, can force expansion wire cylinder to move ahead, under the effect of screw front end expansion-head, make the front end of expansion wire cylinder outwards expand, taking-up interface final and the intramedullary pin rear end coincide fixing.After treating fixation, can operate the withdrawing device that the extractor rear end is provided with, progressively intramedullary pin be taken out.
Use general-purpose type intramedullary nail extractor described in the utility model, owing to adopted the basic structure and the principle of expansion bolt, so can adapt to the taking-up operation of the intramedullary pin of various models, characteristics with various intramedullary pin taking-up effect versatilities, avoided clinical when making intramedullary pin and taking out because of the not corresponding puzzlement that takes place of model and busy, also avoided simultaneously because of can not in time taking out the misery that intramedullary pin causes to patient.
