Utilize the utility model discloses a atress is more even when the protector can make the breastbone strut, and the oppression hemostasis to the surface of a wound of breastbone simultaneously plays better breastbone guard action, reduces the emergence of complication such as cardiac operation breastbone hemorrhage, breastbone fracture, rib fracture and breastbone healing badness.
Description
Technical Field
The utility model relates to a breastbone distraction protector belongs to medical equipment technical field.
Background
The conventional cardiac surgery requires median sternal sawing, and has the disadvantages of much bleeding and huge wound. In the operation, the sternum spreader is used for separating the sawn sternum, so as to achieve the purposes of fixing the sternum and exposing the operation visual field. But elderly patients and postmenopausal women often have different degrees of osteoporosis. The sternum spreader is difficult to play a role in fixation, so that the incidence rate of sternum fracture and rib fracture is increased, further postoperative pain of a patient is aggravated, and recovery is affected. Meanwhile, bone wax is routinely applied to cut wound surfaces on two sides of a sternum in a heart operation to stop bleeding, but the effect is limited. Particularly for osteoporosis patients, even if a large amount of bone wax is repeatedly applied, blood loss still occurs, but the occurrence of poor sternum healing after operation is obviously increased. At present, the gauze pad is only used clinically to buffer the pressure of the sternum spreader on the sternum, the effect is little, and the sternum bleeding cannot be controlled.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: how to reduce or avoid the occurrence of sternal fractures or rib fractures and reduce sternal bleeding when sternum is spread in cardiac surgery.
In order to solve the technical problem, the technical scheme of the utility model is to provide a sternum spreading protector, which is characterized in that the sternum spreading protector comprises a soft rubber strip, the cross section of the soft rubber strip, which is vertical to the length direction, is of a C-shaped structure or a concave-shaped structure, and a groove on the C-shaped structure or the concave-shaped structure is a clamping groove; a fixing plate is arranged in the soft rubber strip.
Preferably, the soft rubber strip comprises a wide plate positioned in the middle and narrow plates connected to two sides of the wide plate, and the wide plate and the narrow plates on two sides form a C-shaped structure or a concave structure; a clamping groove is formed between the inner side of the wide plate and the inner sides of the two narrow plates; the fixed plate is fixed in the wide plate.
Preferably, the fixing plate is completely wrapped in the soft rubber strip.
Preferably, the soft rubber strip is of an integrally formed structure.
Preferably, the soft adhesive tape is a silica gel strip; the fixed plate is a steel plate.
The soft rubber strip in the utility model is made of silica gel, which has good elasticity limit and can form an elastic buffer zone in the naked area between the sternum and the sternum spreader. Meanwhile, the rigidity strength of the steel plate is utilized to reduce the integral deformation of the silica gel.
Compression hemostasis is one of the commonly used hemostasis methods in surgery and is effective. For sternal bleeding, the effect of only applying bone wax on the wound surface is limited. The soft rubber strip of the utility model can completely cover the wound surface of the sternum, and achieves good compression hemostasis effect by means of the pressure applied when the sternum is propped open.
Compared with the prior art, the utility model discloses a protector has following advantage:
the protector of the utility model can ensure that the stress is more uniform when the sternum is stretched, and meanwhile, the compression hemostasis is carried out on the wound surface of the sternum, thereby playing the good role of protecting the sternum and reducing the complications such as sternum bleeding, sternum fracture, rib fracture, poor sternum healing and the like in cardiac surgery.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model provides a sternum distraction protector, as shown in figures 1-3, which comprises a soft rubber strip 1, wherein the cross section of the soft rubber strip 1, which is perpendicular to the length direction, is of a C-shaped structure or a concave-shaped structure, as shown in figure 3. The groove on the C-shaped structure or the concave structure is a clamping groove 2 used for clamping the end of the sawed sternum. A hard fixing plate 3 is arranged in the soft rubber strip 1.
The soft adhesive tape 1 comprises a wide plate positioned in the middle and narrow plates connected to two sides of the wide plate, the wide plate and the narrow plates on two sides of the wide plate form a C-shaped structure or a concave-shaped structure, and a clamping groove 2 is formed between the inner side of the wide plate and the inner sides of the two narrow plates. The fixed plate 3 is fixed in the wide plate.
In the embodiment, the soft rubber strip 1 is a silica gel strip; the fixed plate 3 is a steel plate; the fixing plate 3 is completely wrapped in the soft rubber strip 1; the soft rubber strip 1 is of an integrally formed structure. Wherein, soft adhesive tape 1 wraps up in the fixed plate 3 outside through moulding plastics.
In the conventional chest-opening operation of cardiac surgery, the protector of the utility model can ensure that the stress of the sawed breastbone is more uniform when the breastbone is opened, and the surface of the wound of the breastbone is pressed at the same time, thereby exerting the functions of breastbone fixation, support and wound compression hemostasis, reducing the incidence of breastbone bleeding, breastbone fracture and rib fracture in the cardiac operation and effectively protecting the breastbone.
The soft rubber strip 1 has the length of 10-20cm, the width of 2cm and the thickness of 1cm. The inner diameter (namely the distance between the two narrow plates) of the clamping groove 2 is 1.2cm, and the depth is 0.4cm.
In the embodiment, the length of the soft rubber strip 1 has three specifications of 10cm, 15cm and 20cm respectively, and corresponds to sternal incisions with different lengths; the fixing plate 3 has three specifications of 6cm, 9cm and 16cm corresponding to the lengths of the soft rubber strips 1.
The utility model discloses a use as follows:
the protector of the utility model is a disposable consumable material, and is used for the thoracotomy operation of the cardiac surgery after ethylene oxide sterilization. After the sternum is sawed, hemostasis is performed conventionally, and bone wax is smeared. And selecting the sternum distraction protector with corresponding specification according to the length of the sternum incision. Two flexible glue strips 1 of the utility model are respectively fixed on the two sides of the sternum which is sawn through the clamping grooves 2. Four spreading claws of the sternum spreader are fixed on the soft adhesive tape 1, and the original gauze pad is replaced by the soft adhesive tape 1. The sternum is opened, the operation field is exposed, and the operation is performed.
The soft rubber strip 1 which is basically as long as the sternum can ensure that the sternum is stressed more uniformly when being unfolded. Meanwhile, the elastic action of the soft rubber strip 1 made of silica gel is utilized to reduce the direct injury of the sternum spreader to the sternum and reduce the occurrence of sternum fracture. The thin steel plate can reduce the deformation of the silica gel strip under stress after the sternum is unfolded, and the stability of the instrument is ensured. In addition, through the complete cover to the surface of wound of sternum to utilize the pressure that receives when the sternum struts, the utility model discloses a protector can play good hemostasis by compression effect to the both sides surface of wound of sawing the sternum, reduces the blood loss in the art.
