Cardiothoracic surgery studies the treatment of cardiac and large vessel trauma, pericardial disease, congenital heart disease, acquired valvular heart disease, large vessel disease, interventional treatment techniques, etc. Cardiothoracic surgery uses a fixed chest belt during treatment. The bound chest belt is used to apply pressure to the surgical site to stop bleeding, prevent postoperative incision rupture, and relieve postoperative pain.

[0003] For example, the document with the prior art publication number CN 215385198 U provides a chest strap for cardiothoracic surgery, which includes a front chest cloth, a first shoulder strap is installed on the side of the front chest cloth, a first fixing ring is provided at one end of the first shoulder strap, a second shoulder strap is provided on the inner side of the first fixing ring, a back chest cloth is installed at one end of the second shoulder strap, etc. The device can effectively reduce the pain of patients in the process of wearing or taking off the device through the coordinated use of the first fixing ring, the second shoulder strap, the first fixing belt, the second fixing ring and the second fixing belt, making it more convenient to wear.

[0004] However, the above device has limited effect on the pressure of the surgical site of the patient, and it is not convenient to adjust the pressure for different sites, so that the effect of the chest belt is limited. In view of this, we propose a fixed chest belt for thoracic surgery. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 As shown, a chest strap for thoracic surgery comprises: a front splint 1, which is used for clamping and fixing on the patient's chest; a back plate 2, which is used for being placed on the patient's back and connected to the front splint 1; a tightening mechanism 3, which is installed on the front side of the front splint 1; a pressurizing mechanism 4, which is arranged on the side of the front splint 1 that contacts the patient; and a binding belt 5, which is connected between the front splint 1 and the back plate 2 and is bound to the human body;

[0023] When using the device to pressurize and fix the patient's chest cavity, first place the front splint 1 on the patient's chest and the back plate 2 on the patient's back, and use the straps 5 to bind the front splint 1 and the back plate 2 to clamp and fix the patient's chest cavity. Then connect the pressurizing mechanism 4 to the vacuum pump, and fill different volumes of gas into different airbags 402 in the pressurizing mechanism 4 according to the actual use of the patient's chest cavity to be pressurized, so that the volume of the airbag 402 expands differently, thereby achieving different pressure compensation for different parts of the chest cavity. Different volumes of gas are filled into each airbag 402 according to the actual use, so that the degree of expansion of the airbag 402 is different, so that the device can control the different pressures on various parts of the patient's chest cavity, so that the use effect is better.

[0024] like Figure 2 As shown, the front clamping plate 1 includes a clamping plate 1 101 and a clamping plate 2 102, and the clamping plate 1 101 and the clamping plate 2 102 are connected and adjusted by a tightening mechanism 3, and the tightening mechanism 3 includes a base 301 respectively fixed on the clamping plate 101 and the clamping plate 2 102, and the base 301 installed on the same horizontal plane of the clamping plate 101 and the clamping plate 2 102 is connected with a pull rod 302, and the pull rod 302 is connected with the base 301 by threaded engagement, and the screw threads opened on the inner side of the base 301 installed on the same horizontal plane are arranged in opposite directions, and one end of the pull rod 302 is connected with a force rod 303;

[0025] After the front splint 1 and the back plate 2 are bound to the patient's chest and back by the straps 5, the tightening mechanism 3 is then used to tighten the first splint 101 and the second splint 102. This is to prevent the front splint 1 from being pulled by the straps 5 to drive the skin on both sides of the incision to move away from the incision when the front splint 1 and the back plate 2 are bound by the straps 5, so as to avoid the incision cracking caused by the tension on the skin at the incision;

[0026] When tightening the clamping plate 1 101 and the clamping plate 2 102 by using the tightening mechanism 3, firstly, the two clamping plates 1 101 and the clamping plate 2 102 of the front clamping plate 1 are respectively arranged on both sides of the incision, and the rotation of the force adding rod 303 drives the rotation of the pull rod 302. Through the rotation of the pull rod 302 and the threaded engagement with the base 301, the clamping plate 101 and the clamping plate 2 102 can be driven to approach each other. As the clamping plate 101 and the clamping plate 2 102 fit the skin, the skin on both sides of the incision will be driven to shrink toward the incision, thereby reducing the tension of the skin at the incision and preventing the incision from cracking due to the pulling of the skin.

[0027] The pressurizing mechanism 4 is provided with multiple groups on the side of the first splint 101 and the second splint 102 contacting the patient, respectively. The pressurizing mechanism 4 includes a cloth bag 401 connected to the front splint 1, each cloth bag 401 is stuffed with an air bag 402, and a connecting pipe 403 is installed at the outer end of each air bag 402. A control valve 404 and a pressure gauge 405 are respectively provided on each connecting pipe 403, and the distal end of the connecting pipe 403 is connected to the inflation pump. The structure of the cloth bag 401 is an elastic structure;

[0028] After the front splint 1 and the back plate 2 are bound to the patient's chest and back by the straps 5, different volumes of gas are filled into different airbags 402 in the pressurizing mechanism 4 by an air pump, so that each airbag 402 is expanded to a different volume as required for installation, thereby achieving different pressure requirements for different parts of the chest cavity, and the airbag 402 can be stuffed into the cloth bag 401 for use or removed according to actual usage. When the airbag 402 is inflated, the pressure of the airbag 402 can be observed by using a pressure gauge 405, so that the airbag 402 is filled with appropriate gas as required, and after the air is filled, the control valve 404 is closed to prevent leakage.

[0029] The inner side of the back plate 2 is evenly provided with a plurality of groups of ventilation holes 201. One end of the strap 5 is tied to the side of the back plate 2, and the other end of the strap 5 is connected to the side of the front plate 1. The strap 5 is provided with a Velcro adhesive connection.

[0030] The ventilation holes 201 placed on the back plate 2 can ensure better air permeability during use, thereby avoiding the discomfort caused by the back plate 2 fitting the body and being airtight. When the front splint 1 and the back plate 2 are bound together, the straps 5 are passed around both sides of the patient's body, and then the straps 5 are tightened and fixed with the Velcro included in the straps 5.

[0031] Working principle: when using this device to pressurize and fix the patient's chest cavity, first place the front splint 1 on the patient's front chest, and the back plate 2 on the patient's back, and use the straps 5 to bind the front splint 1 and the back plate 2 to clamp and fix the patient's chest cavity. Then connect the pressurizing mechanism 4 to the vacuum pump, and fill different volumes of gas into different airbags 402 in the pressurizing mechanism 4 according to the actual use of the patient's chest cavity to be pressurized, so that the volume of the airbag 402 expands differently, thereby achieving different pressure compensation for different parts of the chest cavity.
