Abstract

The invention discloses a sternum fixator, which comprises a right hoop, a left hoop, strengthening nails and fixing screws, wherein the strengthening nail, which is arranged at the lower end of the right hoop, is arranged at the right end of the right hoop, and the strengthening nail, which is arranged at the lower end of the left hoop, is arranged at the left end of the left hoop; the right hoop and the left hoop are mutually laminated; the left hoop is arranged above the right hoop; and the fixing screws are inserted in a part wherein the right hoop and the left hoop are mutually laminated. The sternum fixator, during an operation, is simple for stopping bleeding in a surgery field (open sternum from a chest median incision), low in blood consumption for the operation and is capable of greatly shortening an operation duration; the sternum fixator is capable of fixing the sternum tightly, preventing the sternum which is poorly fixed from moving and cutting the sternum, so as to reduce blood oozing and fluid oozing in a wound surface after the operation, shorten a time of drawing a drainage tube, relieve pain in patients, reduce cost and reduce the opportunity of mediastinal infection in the patients; the sternum fixator is convenient to detach, and the sternum fixator can conveniently enter the chest when another operation is required in the early period of post-operation and is reusable; and the sternum fixator disclosed by the invention, which is made from a medical steel material, is convenient in material obtaining, low in cost and is capable of greatly reducing cost, and the sternum fixator, when converted into a finished product, is easy in popularization.

Description

A kind of sternum fixer

Technical field

The invention belongs to medical instruments field, particularly relate to a kind of sternum fixer.

Background technology

Chest median incision is the operating classical otch of cardiovascular injuries, and the operation of this otch menisectomy appears abundant, can complete the cardiovascular disease of more than 90%.Current art finishes closes breastbone and commonly uses steel wire and run through breastbone or parasternal intercostal and be then wound around and close up breastbone.

Surgical wound surface anthemorrhagic difficulty during the breast of prior art pass, wound surface is hemorrhage many, operation blood is many, the pass breast time is long, breastbone fixes bad (breastbone friction sense when postoperative patient has a cough more, it is bad that namely this symptom has pointed out breastbone to fix), severe patient even can cause the cutting of breastbone steel wire to be split, and jeopardizes patient vitals.Also there is sternal fixation device both at home and abroad in recent years, but because of somewhat expensive, be difficult to popularize, promote.

Summary of the invention

The object of the present invention is to provide a kind of sternum fixer, surgical wound surface anthemorrhagic difficulty when being intended to solve the pass breast that prior art exists, wound surface is hemorrhage many, and it is long to close the breast time, and breastbone fixes bad problem.

The present invention aims to provide a kind of sternum fixer, comprises right loop, left loop, strengthening nail, fixed screw; The described strengthening nail being positioned at right loop lower end is arranged on the right-hand member of right loop, the strengthening nail being positioned at left loop lower end is arranged on the left end of left loop, described right loop and left loop laminate mutually, and described left loop is positioned at above right loop, and described fixed screw interts and mutually laminates place at right loop and left loop.

Further, described sternum fixer is split type, and described right loop upper surface and left loop lower surface are crude.

Further, described right loop comprises long-armed, through hole and hook; Offer multiple through hole on right loop is long-armed, through-hole diameter and hold-down screw diameter matches, right loop bottom righthand side arranges a hook.

Further, described left loop comprises long-armed, slotted eye and hook; Offer one section of slotted eye on described left loop is long-armed, slotted eye width and hold-down screw diameter match, and left loop lower-left end arranges a hook.

Further, described sternum fixer using method is:

First, strengthening nail part next-door neighbour parasternal sternal direction is embedded breast bone;

Secondly, by right loop, left loop part next-door neighbour's parasternal embedding breastbone in the middle of strengthening nail part respectively, by the right loop of approximator tractive, left loop part, the breastbone of incision is tightly brought together into together;

Finally, left loop part and right loop part are tightly fixed on breastbone by the aperture of fixed screw part along right loop part.

Further, described approximator comprises left and right; Described left comprises approximator left arm, left fixing point, approximator left circular hole and approximator left hook, described right comprises approximator right arm, right fixing hole, right holddown groove, approximator right circular hole and approximator right hook, described approximator left circular hole and approximator left hook lay respectively at approximator left arm two ends, and left fixing point is between approximator right circular hole and approximator right hook; Described approximator right circular hole and approximator right hook are positioned at approximator right arm two ends, and right fixing hole and right holddown groove are all between approximator right circular hole and approximator right hook, and right fixing hole is connected with right holddown groove.Left fixing point and right fixing hole diameter match.

Further, described approximator using method is:

First left fixing point is put into right holddown groove through right fixing hole;

Secondly be enclosed within dilator two-arm respectively by left for an approximator circular hole and approximator right circular hole holes, along with the movement of dilator two-arm, the distance between approximator left hook and approximator right hook moves change, thus by the breastbone that cuts to together.

Sternum fixer provided by the invention is split type, and compared with prior art tool has the following advantages:

1) visual area (chest median incision cuts breastbone) hemostasis is simple, and in art, blood using amount is few, greatly shortens operating time.

2) breastbone is fixing tight, can not fix bad and occur that breastbone is movable, cutting breastbone, and then can reduce the sepage of postoperative wound surface oozing of blood, shortening and pull out the drainage tube time, alleviate patient suffering, reduce expense, reduce patient's mediastinal infection chance.

3) convenient disassembly, as early postoperation need be performed the operation again, enters breast convenience and can reuse.

4) material of the present invention is medical steel, draw materials conveniently, cheap, cost reduces greatly, is easy to promote, popularize after being converted into product.

5) the present invention makes breastbone fixing tight, there will not be breastbone fix bad and have breastbone bone rubbing feeling, also would not occur that breastbone cuts, be conducive to breastbone healing, and convenient disassembly.
