Technical Field

The invention relates to the technical field of medical instruments, in particular to a high-strength chest closing bandage for a chest opening operation.

Background

With the continuous improvement of the medical technology level, the median thoracotomy still accounts for a high proportion, and most of the heart, pericardium and partial mediastinum surgeries involve the median thoracotomy. In the early mid-thoracotomy, the sternum is bound by the metal wire mostly when closed, but the sternum is very easy to cut and damage due to the thin metal wire, so that severe complications such as poor sternum healing, mediastinal infection and the like are caused, and the postoperative mortality is increased. Moreover, a series of problems such as bleeding and fracture of the marrow cavity and tissues are easily caused. Although the later developed cable ties can effectively avoid many adverse effects caused by the thinner wires, there are still many problems.

Chinese patent document CN106798585A discloses a bandage for sternal median incision suture fixation, which comprises a flexible band and a hook-shaped suture needle, wherein the flexible band comprises a front part and a rear part which are connected, one end of the front part far away from the rear part is connected with the tail part of the hook-shaped suture needle, one end of the rear part far away from the front part is connected with a fastening device, the front part is a vertebral body with a gradually reduced section size along the direction far away from the rear part, and the inner side of the rear part is provided with a unidirectional tooth socket matched with the fastening device. As is clear from fig. 1 of the patent document, the thickness of the fastening device is twice or more of that of the flexible band, and the fastening device has a substantially square structure, and after the sternum is tied, the fastening device protrudes more from the sternum regardless of whether the left side (left side in fig. 1) or the upper side (upper side in fig. 1) is oriented forward, and rubs the surrounding tissues, which is likely to cause injury or infection, and further, the fat tissue in front of the sternum is very thin, which causes a large discomfort.

Besides the fact that the currently used straps cause great discomfort to patients, the currently used straps are expensive, one is up to five or six thousand yuan, at least 3 straps are generally needed for closing the chest, the operation cost is obviously increased, and the frosting on the snow is undoubtedly caused to the patients with family difficulties. In view of the above, there is a need for a high strength chest closing strap that reduces patient discomfort and is inexpensive.

Disclosure of Invention

In order to solve the problems, the invention provides a high-strength chest closing bandage for an open chest operation, the bandage head of the chest closing bandage is of a U-shaped structure, locking teeth I are symmetrically arranged on the inner walls of two side plates, locking teeth II matched with the locking teeth I are symmetrically arranged on two sides of a flexible bandage body, the flexible bandage body is pulled out from the bandage head, so that the locking teeth II on two sides of the flexible bandage body are matched with the locking teeth I on the two side plates of the bandage head to realize locking, after the chest closing bandage is used for carrying out closure and fixation on sternum, no obvious bulge exists, the discomfort of a patient can be obviously reduced, the price is low, and the economic burden of the patient can be greatly relieved.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

A high-strength chest closing tie for open chest surgery comprises a tie head 1 and a flexible tie body 2 which are connected with each other, wherein the tie head 1 is of a U-shaped structure and comprises a bottom plate 11 and two side plates 12, at least one pair of first locking teeth 13 is symmetrically arranged on the inner walls of the two side plates 12, and a plurality of second locking teeth 21 matched with the first locking teeth 13 are symmetrically arranged on two sides of the flexible tie body 2.

When the chest closing bandage is used, the flexible band body 2 is pulled out from the bandage head 1, the locking teeth II 21 on the two sides of the flexible band body 2 are matched with the locking teeth I13 on the two side plates 12 of the bandage head 1, locking is achieved, after the chest closing bandage is used for sternum closure and fixation, no obvious bulge exists, discomfort of a patient can be obviously reduced, the price is low, and the economic burden of the patient can be greatly relieved.

In a specific embodiment, as shown in fig. 1, the bottom plate 11 of the banding head 1 is provided with an elastic groove 14 at the position corresponding to the locking teeth 13 at the two sides. The elastic groove 14 is arranged to enable the position of the locking teeth 13 on the two side plates 12 to have certain elasticity, and the position can be slightly opened outwards in the process that the flexible band body 2 passes through the band binding head 1, so that the flexible band body 2 can pass through smoothly until the proper position is reached.

In a specific embodiment, as shown in fig. 1, the two side plates 12 are provided with inwardly protruding reinforcing plates 15 at positions corresponding to the elastic grooves 14 on the side away from the bottom plate 11. The reinforcing plate 15 can restrain the flexible strap 2 between the reinforcing plate 15 and the base plate 11 to prevent the flexible strap 2 from separating upward from the tie head 1.

In a particular embodiment, as shown in fig. 1, the reinforcing plate 15 is provided with a slot 16 in the middle. The reinforcing plates 15 are arranged to cause the hardness of the corresponding parts to be larger, so that the positions of the two side plates 12 provided with the first locking teeth 13 are not easy to open outwards, and the smooth passing of the flexible belt body 2 is not facilitated, therefore, the grooves 16 are arranged in the middle of the two reinforcing plates 15, and the smooth passing of the flexible belt body 2 is facilitated.

In a specific embodiment, as shown in fig. 1-2, the flexible band body 2 comprises a connecting section 22, a fixing section 23 and an inserting section 24, wherein the connecting section 22 is used for connecting with the binding head 1, the locking teeth 21 are arranged on two sides of the fixing section 23, and the inserting section 24 is tapered towards one end far away from the fixing section 23. The end of the insertion section 24 is thin to facilitate smooth passage between the ribs.

In one embodiment, as shown in FIG. 1, three locking teeth 13 are provided on the inner side wall of each side plate 12.

In a particular embodiment, the pitch of the second locking tooth 21 is 0.3 to 1.3mm, preferably 0.5 to 1 mm. The tooth pitch of 0.5-1mm can ensure that the binding belt keeps the state that the sternums on the two sides are attached.

In a particular embodiment, the thickness of the flexible strip 2 is between 0.3 and 1.5mm, preferably between 0.5 and 1 mm. The thickness of the whole bandage is very small, the thickest part after locking is only 1.5-2.5mm, and can not obviously protrude out of the sternum, so that the injury, infection and the like caused by the friction of surrounding tissues can be effectively avoided.

In a particular embodiment, the width of the flexible strip 2 is 3-8mm, preferably 3-5 mm. The width of the flexible band body 2 is designed to be 3-5mm to achieve the strength required by the band for closing the chest, and even the gap between the two lowest ribs can be easily penetrated.

In a specific embodiment, the chest closing strap is made of PEEK material. The PEEK material has high strength and high toughness, can completely meet the strength requirement of the sternum closure bandage, and has high biocompatibility, and the sternum can be taken out without an operation after being healed.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
