Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an impedance feedback monitoring system during SNM surgery. Background Art

[0002] During the implementation of pediatric sacral neuromodulation, since direct feedback from the child cannot be obtained, during impedance testing during the operation, the electric stimulation intensity and mode both depend on the experience of the surgeon and visual observation of whether the patient shows positive signs (such as anal wind-like contraction, plantar flexion reflex, gastrocnemius contraction, etc.). Due to the unreliability of visual observation, a more objective and accurate evaluation device is needed during impedance testing during the operation and when exploring the appropriate electric stimulation intensity and mode.

[0003] During existing surgeries, in order to observe such positive signs, non-surgical areas such as the perineum area need to be exposed to the surgical field during the operation, increasing the risk of intraoperative infection. Summary of the Invention

[0004] The purpose of the utility model is to solve the drawback that during existing surgeries, in order to observe such positive signs, non-surgical areas such as the perineum area need to be exposed to the surgical field during the operation, increasing the risk of intraoperative infection, and to propose an impedance feedback monitoring system during SNM surgery.

The acquisition and analysis unit acquires data, the data comparison unit compares the acquired data with normal data, the judgment unit is used to judge the result of the comparison, and the early warning unit is used to give an early warning of abnormal results.

[0017] Preferably, the plug-type sensor is used to fit the inner wall of the patient's anus.

[0018] Preferably, the needle-shaped electrode monitors the contraction of the gastrocnemius muscle to the greatest extent, reducing the occurrence of postoperative complications.

[0026] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present embodiment, rather than all the embodiments.

[0027] Embodiment 1

[0028] The following further elaborates on this application in conjunction with Figure 1 - Figure 2 to make a further detailed description of this application.

[0029] An impedance feedback monitoring system during SNM surgery includes:

[0030] A display device for displaying data results,

[0031] A terminal module for operation control, connected to the display device;

[0032] A data storage module for data storage, connected to the terminal module;

[0033] A feedback mode analysis and warning module for analyzing, judging, and warning data, connected to the display device;

[0034] An anal pressure mode analysis module, connected to the feedback mode analysis and warning module, is a plug-type sensor;

[0035] A gastrocnemius electromyogram recording module, connected to the feedback mode analysis and warning module, is a needle electrode;

[0036] A plantar electromyogram recording module, connected to the feedback mode analysis and warning module, for recording the plantar electromyogram during the impedance test of the patient;

[0037] A pelvic floor electromyogram recording module, connected to the feedback mode analysis and warning module;

[0038] An electrocardiogram detection module, connected to the feedback mode analysis and warning module.

[0039] In this embodiment, the feedback mode analysis and warning module includes an acquisition and analysis unit, a data comparison unit, a judgment unit, and a warning unit. The acquisition and analysis unit acquires data, the data comparison unit compares the acquired data with normal data, the judgment unit is used to judge the result of the comparison, and the warning unit is used to warn of abnormal results;

[0040] Through program programming for automatic analysis, conclusions can be analyzed and obtained for the surgeon's reference in the first time after data collection. At the same time, this program can also be used as a warning system to monitor and warn in time of a series of symptoms that may be caused by electrical stimulation during the operation of the patient. Thanks to the development of semiconductor technology, there is no need to design dedicated hardware for this function. After writing a specific program and installing it as software on a portable tablet computer, the three functions of data processing, warning device, and display can be realized simultaneously. At the same time, the system is given the characteristics of portability, modularity, and customization. If connected to the network function, through the analysis of big data, it may be possible to customize personalized electrical stimulation modes for patients, further improving the curative effect and reducing the occurrence of complications.

[0041] In this embodiment, the anal pressure mode analysis module: It is the core module of the system and is a plug-type sensor. The plug-type sensor is used to fit the inner wall of the patient's anus.

[0042] This module is used to capture changes in anal pressure during impedance testing to determine whether the anus contracts, the contraction duration, and the contraction intensity, and conduct the corresponding waveform to the display device. It is used to record anal contractions without visual observation (the accuracy should be more accurate than visual observation), and hand it over to the operator to judge whether the patient's current electrical stimulation is effective. Therefore, at least one pressure sensor should be configured for this module.

[0043] In addition to simply recording changes in anal pressure, if the accuracy and quantity of the pressure sensor can be improved, the anal contraction mode of the patient can be evaluated more accurately, and it may be used to collect data and analyze the association between different anal contraction modes and the curative effect after SNM during different impedance tests.

[0044] The principle is similar to the anal manometry tube in the urodynamic instrument, but the anal manometry tube records pressure through water pressure, which more reflects the change of the patient's abdominal pressure. The detection head of this device uses a semiconductor pressure sensor to directly record the pressure generated by the patient's anal sphincter, which is not affected by abdominal pressure.

[0045] Technically speaking, it is understood that both the simple pressure recording device described above and the high-precision pressure sensor can be achieved with existing technologies, and there are even similar principle products on the market. After novelty search, there is no dedicated anal sphincter pressure recording device for SNM described in this article.

[0046] After this module is connected to the display device as an independent product, it can achieve the feedback monitoring without visual observation as described above, and reduce the risk of intraoperative infection.

[0047] In this embodiment, the gastrocnemius electromyogram recording module: It is an important component module of the system and is a needle electrode. Since the patient is in a general anesthesia state, the needle electrode will not cause pain to the patient, and the needle electrode has the highest sensitivity to capturing the contraction of the gastrocnemius. Research shows that the contraction of the gastrocnemius during impedance testing is strongly correlated with symptoms such as postoperative pain, a feeling of electric current, and even difficulty walking. Therefore, using a needle electrode can monitor the contraction of the gastrocnemius to the greatest extent and reduce the occurrence of postoperative complications as much as possible.

[0048] This module cannot be used as an independent product alone. It can be combined with the anal pressure mode analysis module described above and the plantar electromyogram recording module to be described later into a product, which is the most core configuration of the impedance feedback monitoring system envisioned in this article.

[0049] In this embodiment, the plantar electromyography recording module is the same as the gastrocnemius electromyography recording module, and the module is used to record the plantar electromyography of the patient during the impedance test. The patient's plantar flexion reflex is also an important sign of the success of the impedance test, just like the anal bellows-like contraction. The electrode used in the plantar electromyography is a patch electrode, which can be designed as a square sticky gel electrode sheet of a certain size, and can be customized according to the patient's foot shape to avoid problems such as incomplete electromyography signal collection.

[0050] In this embodiment, pelvic floor electromyography recording module: A considerable proportion of patients with neurogenic bladder have symptoms of pelvic floor dysfunction. Some studies have pointed out that pelvic floor dysfunction is the main cause of defecation and urination disorders. In recent years, pelvic floor electromyography has also become one of the common functions in NB-related medical instruments. By judging whether the contraction pattern of the patient's pelvic floor muscles has changed during surgery, the improvement of defecation and urination disorders after SNM surgery can be predicted to a certain extent.

[0051] In this embodiment, the ECG detection module, studies have shown that SNM's electrical stimulation of the vagus nerve may affect cardiac electrophysiology, so a separate ECG detection module may be needed. Different from the ECG detection equipment routinely equipped in the operating room, the system can connect two leads separately and integrate them into the screen display device, allowing the operator to more comprehensively evaluate the impact of the impedance connection on the patient. Since the integrated factors related to SNM can be displayed on the same device, it has stronger synchronicity. Therefore, if the ECG changes significantly, the correlation with the electrical stimulation can be evaluated in time.

[0052] Embodiment 2

[0053] refer to Figure 3 , Embodiment 2 is the same as the rest of Embodiment 1, except that: a wireless module is connected to the terminal module for wireless data transmission, the wireless module is connected to multiple mobile terminals, and the detection results are transmitted to the multiple mobile terminals wirelessly. The mobile terminals are mobile phones of doctors and patients. This application includes all the structural shapes, sizes and materials of Embodiment 1. In order to meet the specific usage conditions, they can be selected and adjusted. The accompanying drawings are all schematic structural diagrams, and the specific actual sizes can be appropriately adjusted.

[0054] The above is only a preferred specific implementation of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of this embodiment within the technical scope disclosed in this embodiment, which should be covered by the protection scope of this embodiment.
