Description

Flexible sternum bandage without injury

Technical Field

The utility model relates to a nondestructive flexible sternum binding tape, and belongs to the technical field of medical devices.

Background

To provide access to certain internal anatomical structures during open heart surgery, such as cardiac surgery, a median sternal incision is often used. The median sternal incision is made substantially along the midline of the sternum, dividing the ribcage into two free sides and allowing the surgeon to move the ribcage to provide surgical access to the heart. After the open heart operation is completed, the sternum needs to be aligned, tied and fixed so as to facilitate the growth and healing of the two free edges of the sternum.

In normal anatomical function, forces acting on the sternum may be generated, for example, during respiration, body movement, and handling of objects. One conventional method for sternum fixation is to use stainless steel suture, which is tied and locked by screwing the free ends of the two ends, which is prone to fracture at the screwed steel wire during the process. Too tight a wire binding may result in a sternal cut due to the small diameter of the wire.

At present, the sternum ligature on the market is a metal wire with a puncture needle at the head, and the sternum ligature needs to pass through the gap of the rib of the chest of a human body under the guidance of the puncture needle when in use; then the puncture needle is removed, and the tail part of the metal wire is combined with the independent locking buckle by using an auxiliary tool and then is fastened, so as to achieve the purpose of fixing the sternum.

However, the technical defects of the sternum bandage on the market are as follows:

1. the existing sternum binding line is of a filiform structure, has small contact area with human ribs, and is easy to cut and damage the sternum at the binding part in the using process;

2. when the existing sternum strap line is locked, a single locking buckle is needed or two free ends are screwed and locked, the sternum strap line is easy to drop or the screwed steel wire is easy to break in the using process, and certain operation risk exists.

SUMMERY OF THE UTILITY MODEL

The utility model provides a nondestructive flexible sternum binding belt, which solves the problems in the background technology,

The specific technical scheme is as follows:

a nondestructive flexible sternum bandage comprises a bandage body, wherein the head end of the bandage body is connected with a lock catch, the tail end of the bandage body is fixed with a metal puncture needle, and a protective hoop is arranged on the bandage body in a sliding mode.

The hasp be equipped with clamping part for fixed ribbon head end still is equipped with the perforation, is used for the ribbon other end to pass, the ribbon penetrates from the perforation front end, the rear end is worn out, perforation front end both sides be equipped with a pair of folding earflap, the ribbon passes the back from the perforation rear end, turns over to the perforation front end, is folded by the earflap and pushes down.

The rear end of the through hole is provided with anti-skid sawteeth.

The utility model has the specific technical effects that:

1. flexible sternum bandage without damage: the shape and the structure of the sternum bandage are changed to increase the contact area of the sternum bandage with ribs; the flexibility, the bearing capacity, the binding capacity and the anti-skid lamp supporting effect of the binding belt are improved, so that the damage to ribs in use is reduced;

2. sternal cable ties with a holding and stabilizing lock structure: the design that integrates the sternum strap with the locking buckle to reduce the risk of parts being lost.

Detailed Description

The technical scheme of the utility model is explained by combining the attached drawings.

Example 1

As shown in figures 1 and 2, the nondestructive flexible sternum bandage comprises a bandage 2, the head end of the bandage 2 is connected with a lock catch 1, the tail end of the bandage 2 is fixed with a metal puncture needle 4, and the bandage 2 is further provided with a protective hoop 3 in a sliding manner.

As shown in fig. 3, 4 and 5, the buckle 1 is provided with a clamping part 13 for fixing the head end of the ribbon 2, and a through hole 11 for the other end of the ribbon 2 to pass through, the ribbon 2 penetrates through the front end and the rear end of the through hole 11, a pair of foldable ear wings 12 are arranged on two sides of the front end of the through hole 11, and the ribbon 2 is folded to the front end of the through hole 11 after passing through the rear end of the through hole 11 and is folded and pressed by the ear wings 12.

A through hole 11 is arranged in the lock catch 1, and the ribbon 2 can smoothly penetrate through the through hole 11 and is not deviated; a metal puncture needle 4 is fixed at the tail end of the binding belt 2;

the binding belt 2 is of a sheet structure made of medical stainless steel or titanium, the contact area of the binding belt with the binding belt is greatly increased compared with that of the existing filiform sternum binding belts in the market, and the pressure and damage to the ribs at the binding position are greatly reduced. The protective band 3 can be slid along the band 2 and moved to the side of the rib in operation to eliminate lateral trauma thereto by the sternal band.

The lock catch 1 and the binding belt 2 are of an integrated structure, when the sternum binding belt needs to be locked, the metal puncture needle 4 needs to be cut off, the binding belt 2 penetrates through the front end of the through hole 11, the rear end of the binding belt penetrates out, the binding belt is tensioned, after the binding belt 2 reaches the required locking force, the binding belt 2 is reversely folded to the front end of the through hole 11, and the binding belt 2 can play a non-return effect after being bent, so that the binding belt cannot be withdrawn; when the ribbon needs to be tightened again, the ribbon needs to be pulled rightwards again and bent upwards; when the expected effect is achieved, the redundant ribbon is cut off, the ribbon head is folded back to be attached to the locking surface and is folded and pressed by the ear wings 12, so that the anti-slipping performance is ensured.

Example 2

The structure is the same as that of the embodiment 1, and on the basis of the embodiment 1, as shown in fig. 6 and 7, the rear end of the perforation 11 is provided with anti-skid sawteeth 14. The procedure used is as in example 1, FIG. 8.

The lock catch 1 and the binding belt 2 are of an integrated structure, when the sternum binding belt needs to be locked, the metal puncture needle 4 needs to be cut off, the binding belt 2 penetrates through the through hole 11 to be tensioned, after the binding belt 2 reaches the required locking force, the binding belt 2 is bent along the through hole 11, the non-return effect can be achieved after the binding belt 2 is bent, and the non-return effect can be increased through the anti-slip saw teeth 14, so that the sternum binding belt cannot be withdrawn; when the ribbon needs to be tightened again, the ribbon 2 needs to be pulled again and bent upwards; when the expected effect is achieved, a certain length of the binding tape is reserved, the redundant binding tape is cut off, the end of the reserved binding tape is folded back to be attached to the surface of the through hole 11, and the ear wings 12 are folded to be attached to ensure that the binding tape is prevented from slipping off.
