Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prosthetic valve health monitors, in particular to a nasal cavity postoperative prosthetic valve health monitor. BACKGROUND

[0002] With the continuous development of endoscopic transnasal skull base surgery, the proper selection of free skin flaps for skull base reconstruction and repair is becoming increasingly important. Nasal septal flap (NSF) is a popular and simple choice as the main force for skull base reconstruction and repair material, but in some cases, a single NSF cannot meet the needs of repair and reconstruction, and needs to be combined with multiple other pedicle or vascular flaps for repair, such as NSF failure, nasal septum trauma or large area of defect. These options mainly include pedicle buccal flap, pericranial flap and temporal parietal fascial flap. In some rare cases, larger vascularized tissue flaps are needed than pedicle tissue, such as recurrent cerebrospinal fluid leakage, large area of defect after tumor resection, skull base osteomyelitis or radiation osteonecrosis caused by bone damage. Vascularized free flaps can provide sufficient area for effective repair coverage in these complex cases.

[0003] The prosthetic flap after surgery needs to be pressed by a water bag or tampon for a sufficient period of time to ensure that the defect tissue can heal well. In order to evaluate the health status of the prosthetic flap, endoscopic examination is usually used to judge the health degree of the prosthetic flap at present. Since endoscopic examination can only observe the surface of the prosthetic flap, it cannot effectively remove secretions, which leads to the inability to timely discover early prosthetic flap vascular pedicle compression or tissue infection, which easily causes the risk of prosthetic flap ischemia and necrosis, and also cannot reduce the risk of prosthetic flap infection caused by secretions accumulation.

[0032] The nasal cavity postoperative repair flap health monitor mainly includes: drainage tube 100, blood oxygen pulse sensor 111 and flexible circuit board 131.

[0033] The drainage tube 100 has opposite proximal end and distal end, the distal end is curved along its radial direction to form a drainage part, the drainage tube 100 is provided with a drainage channel 110, one end of the drainage channel 110 is used to connect a negative pressure device, the other end penetrates the drainage part to form a drainage port. In actual use, the proximal end faces the medical staff, and the distal end faces the patient. Connect the negative pressure device with the drainage channel 110, preferably, a connecting pipe for connecting the negative pressure device is arranged on the proximal end, the negative pressure device is a negative pressure aspirator with adjustable pressure value, and the drainage part is fixedly placed around the nasal cavity repair flap.

[0034] The blood oxygen pulse sensor 111 is arranged in the drainage port, and an electrical interface 140 is arranged at the proximal end. A flexible circuit board 131 is arranged in the drainage channel 110 and is electrically connected to the electrical interface 140 and the blood oxygen pulse sensor 111. In actual use, the electrical interface 140 can be connected to a computer to read and record the data of the blood oxygen pulse sensor 111, so as to record the blood oxygen level and pulse of the repair flap, realize real-time monitoring of the blood oxygen level of the skin flap and mucosal flap, evaluate the health status of the repair flap, and timely adjust the water bag compression force through real-time evaluation of the health status of the repair flap, thereby reducing the risk of repair flap necrosis.

[0035] The repair flap after surgery needs to be compressed by a water bag or a tampon for a sufficient time to ensure that the defect tissue can heal well. In order to evaluate the health status of the repair flap, the current method usually uses an endoscope to judge the health degree of the repair flap. However, the endoscope can only observe the surface of the repair flap and cannot effectively remove the secretions, so that the early compression of the vascular pedicle of the repair flap or the infection of the tissue cannot be found in time, which easily causes the risk of repair flap ischemia and necrosis, and cannot reduce the risk of infection of the repair flap caused by the accumulation of secretions.

[0036] The blood oxygen pulse sensor 111 is arranged in the drainage port, and an electrical interface 140 is arranged at the proximal end. A flexible circuit board 131 is arranged in the drainage channel 110 and is electrically connected to the electrical interface 140 and the blood oxygen pulse sensor 111. In actual use, the electrical interface 140 can be connected to a computer to read and record the data of the blood oxygen pulse sensor 111, so as to record the blood oxygen level and pulse of the repair flap, realize real-time monitoring of the blood oxygen level of the skin flap and mucosal flap, evaluate the health status of the repair flap, and timely adjust the water bag compression force through real-time evaluation of the health status of the repair flap, thereby reducing the risk of repair flap necrosis.

[0037] In some embodiments, as shown in Figure 2 , Figure 4 The nasal cavity postoperative repair flap health monitor further includes a flexible support plate 130 arranged in the drainage channel 110, and the flexible circuit board 131 is arranged in the flexible support plate 130. The flexible support plate 130 can waterproof the flexible circuit board 131, and also enhances the strength of the flexible circuit board 131.

[0038] In some embodiments, as shown in Figure 2 , Figure 4 The drainage tube 100 is a flexible hose, and preferably is made of a material such as silicone that has elasticity, and the distal end is flexible, so that the drainage tube 100 can be placed around the repair flap in the nasal cavity.

[0039] The postoperative nasal cavity repair flap health monitoring device also includes a shape memory metal wire 132. The shape memory metal wire 132 is positioned within the flexible support plate 130 along the length of the drainage tube 100, and is used to maintain the shape of the drainage tube 100. Specifically, the shape memory metal wire 132, also known as shape memory alloy (SMA), is a special metallic material that can recover its original shape under specific conditions. After being shaped, the shape memory metal wire 132 bends the originally straight drainage tube 100 into a drainage tube 100 with its distal end bent radially. It can be straightened by applying a force in the opposite direction to the distal end of the drainage tube 100. Because the shape memory metal wire 132 has the characteristics of being able to be shaped at high temperatures, stretched or deformed at low temperatures, and remembering and recovering its original shape after reheating, the shape of the drainage tube 100 can be changed by temperature to make it suitable for different patients.

[0040] In some embodiments, such as Figure 2 , Figure 4 As shown, the postoperative nasal cavity repair flap health monitoring device also includes: a drive channel 120, which is arranged inside the drainage tube 100 along the length direction of the drainage tube 100, and the drive channel 120 is separated from the drainage channel 110 by a flexible support plate 130. The drive channel 120 is used to adjust the orientation of the drainage port.

[0041] Specifically, by inflating, inhaling, and placing the driving device in the driving channel 120, medical staff can control the orientation of the drainage port through the driving channel 120 so that the drainage port can easily reach the area around the nasal cavity repair flap.

[0042] In some embodiments, such as Figure 4 As shown, the postoperative nasal cavity repair flap health monitoring device also includes: a drive rope 121, which is slidably disposed in the drive channel 120, with one end of the drive rope 121 connected to the end of the drainage tube 100 facing the drainage port and the other end forming a drive part.

[0043] Specifically, since the length of the drive channel 120 remains constant along the longitudinal direction of the drainage tube 100, the drive portion of the drive rope 121 moves away from the drainage opening, thus straightening the shape of the drive channel 120 and consequently straightening the shape of the drainage tube 100. Conversely, the drainage tube 100 can be bent by the drive of the shape memory wire 132. Medical personnel can control the orientation of the drainage opening through the drive rope 121 so that the drainage opening can easily reach the area around the nasal cavity repair flap.

[0044] In some embodiments, such as Figures 3 to 4 As shown, the postoperative nasal cavity repair flap health monitoring device also includes: an adjustment sleeve 150, which is slidably fitted on the drainage tube 100 and connected to the drive unit.

[0045] Specifically, the driving channel 120 is separated from the drainage channel 110, and an opening is arranged on the end of the driving channel 120 away from the drainage port and penetrating the drainage tube 100, and the driving rope 121 is connected with the adjusting sleeve 150 through the opening. In actual use, the driving part can be moved towards or away from the drainage port by sliding the adjusting sleeve 150 towards or away from the drainage port, so as to bend or straighten the drainage tube 100, and the medical staff can easily control the orientation of the drainage port so that the drainage port can easily reach around the nasal cavity repair flap.

[0046] In some embodiments, as shown in Figures 1 to 4 , the electrical interface 140 is arranged on the drainage tube 100 in the radial direction of the drainage tube 100, and the electrical interface 140 is electrically connected with the blood oxygen pulse sensor 111 penetrating the drainage tube 100. In actual use, the corresponding data line can be plugged into the electrical interface 140 to connect the computer.

[0047] In some embodiments, as shown in Figure 1 , the nasal cavity postoperative repair flap health monitor further comprises a display terminal 200, the display terminal 200 is detachably connected with the electrical interface 140, and the display terminal 200 is used to display the data of the blood oxygen pulse sensor 111.

[0048] Specifically, the display terminal 200 can be provided with a display and a battery, and when it is needed to display the data of the blood oxygen pulse sensor 111, the display terminal 200 can be plugged into the electrical interface 140. Preferably, the display terminal 200 is further provided with a USB interface and a Bluetooth communication module, which facilitates plugging into the computer or recording data through the Bluetooth host computer.

[0049] In some embodiments, as shown in Figures 1 to 4 , the blood oxygen pulse sensor 111 comprises a reflective blood oxygen sensor;

[0050] a reflective pulse sensor, the reflective blood oxygen sensor and the reflective pulse sensor are in the same direction. The reflective blood oxygen sensor and the reflective pulse sensor are mature, low in cost, and easy to miniaturize, and are suitable for this scene.

[0051] In some embodiments, as shown in Figures 1 to 4 , the nasal cavity postoperative repair flap health monitor further comprises a handheld part 160, the handheld part 160 is arranged on the proximal end, and the handheld part 160 is fixedly sleeved on the drainage tube 100. Since the drainage tube 100 is thin, the medical staff can easily grasp it through the handheld part 160.
