Description

Nondestructive flexible sternum binding belt with self-locking structure

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a nondestructive flexible sternum bandage with a self-locking structure.

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, thereby separating 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.

The sternum ligature on the market at present is a metal wire with a puncture needle at the head, and the sternum ligature needs to penetrate 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.

As mentioned above, the technical drawbacks of the sternal bandages currently 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 bandage with a self-locking structure, which has the following advantages:

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 of the bandage is improved, so that the damage to the ribs in use is reduced;

2. sternum ribbon with self-locking structure: the sternum bandage and the locking buckle are integrally designed so as to reduce the risk of dropping parts;

3. the sternum bandage has the advantages of simple structure (the main body is only composed of two stamping parts), simple process and low manufacturing cost, and further relieves the economic pressure of patients.

In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides a flexible sternum ribbon of not damaged with auto-lock structure, is including hasp and the ribbon that links together, the inside of hasp is equipped with the one-way shell fragment with hasp integrated into one piece, set up on the ribbon a plurality of and one-way shell fragment complex tooth and detain, the ribbon tail end is fixed with the metal pjncture needle.

As a further description of the above technical solution:

the holes are close to the tail of the binding belt.

As a further description of the above technical solution:

the plurality of tooth buckles are arranged at intervals.

As a further description of the above technical solution:

the ribbon is a sheet-like structure made of medical stainless steel or titanium.

As a further description of the above technical solution:

the ribbon and the lock catch are of an integrated structure.

As a further description of the above technical solution:

the tail end of the binding belt is fixedly connected with the metal puncture needle through press riveting.

The utility model has the following beneficial effects:

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-3, a nondestructive flexible sternum bandage with a self-locking structure comprises a lock catch 1 and a bandage 2 which are connected together, wherein a one-way elastic sheet integrally formed with the lock catch 1 is arranged inside the lock catch 1, a plurality of tooth buckles matched with the one-way elastic sheet are arranged on the bandage 2, and a metal puncture needle 3 is fixed at the tail end of the bandage 2; the holes are close to the tail of the binding belt, and the tooth buckles are arranged at intervals;

in this embodiment, the bandage 2 is a sheet-like structure made of medical stainless steel or titanium, and the contact area between the bandage and the bundling part is greatly increased compared with that of the existing filiform sternum bandage in the market, so that the pressure and damage to the ribs at the bundling part are greatly reduced.

In this embodiment, the binding band 2 and the lock catch 1 are of an integrated structure, the lock catch 1 and the binding band 2 of the sternum binding band are of an integrated structure, when the sternum binding band needs to be locked, a puncture needle needs to be cut off, the binding band passes through the lock catch, when the binding band is retracted by the expansion force of the ribs, as shown in the arrow direction in fig. 3, the one-way elastic piece of the lock catch can be clamped into the tooth catch of the binding band, so that the binding band cannot be retracted; when the ribbon needs to be tightened, the ribbon needs to be pulled rightwards, and the one-way elastic piece can be jacked up until the one-way elastic piece falls into the next tooth buckle of the ribbon, so that the action mechanism which is continuously locked and cannot be retracted is formed.

In the embodiment, the tail end of the binding belt 2 is fixedly connected with the metal puncture needle 3 through press riveting.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
