Problems solved by technology

The system uses a pressure sensor to monitor the intestinal signal, which overcomes the problem that patients cannot perceive the amount of feces in the traditional artificial anal sphincter; the internal system and the external system are connected through a wireless communication module, which overcomes the problem of inconvenient control of the traditional artificial anal sphincter; The implanted system uses percutaneous energy supply technology to provide energy, which overcomes the problem of wire infection that may be caused by traditional artificial anal sphincter

Embodiment 1

[0026] See figure 1 , The present feedback artificial anal sphincter system based on percutaneous energy supply includes two parts, an implanted internal system (1) and an extracorporeal system (2), and is characterized in that the implanted internal system (1) consists of a sensing execution module ( 3). The in vivo part of the transcutaneous energy supply module (4) and the in vivo part of the wireless communication module (5) are composed. The extracorporeal system (2) consists of the in vitro part of the transcutaneous energy supply module (4) and the wireless communication module ( 5) The external part of the body, MCU (6), portable control module (7) and external alarm module (8); the output end of the transcutaneous energy supply module (4) is connected to the sensing execution module (3) and wireless The communication module (5) provides energy to the two modules, the sensor execution module (3) is bidirectionally connected to the wireless communication module (5) for bi...

Embodiment 2

[0028] This embodiment is basically the same as the first embodiment, the special features are: see figure 2 The structure of the signal conditioning circuit in the sensing execution module (2) is that the two output voltage terminals of a pressure measuring circuit (9) are connected to the two voltage input terminals of a precision instrument amplifier (10), and the precision instrument The output end of the amplifier (10) is connected to the input end of an active filter (11), and the output end of the active filter (11) is connected to the input end of a passive filter (12). The output terminal of 12) is connected to an MCU (13) with a 10-bit ADC; the resistors R1 and R2 in the active filter (11) are connected in series and then connected to the positive input of the amplifier. The capacitor C1 is composed of the resistor R1 and the resistor The negative input terminal of the amplifier is connected between R2, the negative input terminal of the amplifier is shorted to the ou...

Embodiment 3

[0030] This embodiment is basically the same as the first embodiment, the special features are: see image 3 , The transcutaneous energy supply module includes two parts inside and outside the body. The outside part includes a sinusoidal signal generator (15), a power amplifier (16) and a primary coil (17) connected in sequence, and the inside part includes a secondary coil (18) connected in sequence. ), filter rectifier circuit (19) and voltage stabilizer circuit (20).

[0031] The sinusoidal signal generator of the extracorporeal system generates a sinusoidal AC signal. The signal is amplified by a power amplifier. The amplified signal is input into the primary coil to generate an alternating electromagnetic field. According to the principle of electromagnetic induction, the secondary coil in the body in the electromagnetic field produces a certain amount The induced electromotive force is induced and the induced current is input to the filter rectifier circuit for filtering and...

Abstract

The invention relates to a feedback type artificial anal sphincter system based on percutaneous energy supply. The feedback type artificial anal sphincter system based on percutaneous energy supply comprises a part implanted in vivo and a part implanted in vitro. The system implanted in vivo is composed of a sensing execution module, a part of a percutaneous energy supply module in vivo, and apart of a wireless communication module in vivo. The system implanted in vitro is composed of a part of the percutaneous energy supply module in vitro, a part of the wireless communication module in vitro, a microprogrammed control unit (MCU), a portable control module, and an external alarm module. According to the feedback type artificial anal sphincter system based on percutaneous energy supply, the problems of a traditional artificial anal sphincter that a patient cannot perceive waste volume degree and control is inconvenient, and infection can be led to a wire are solved.

Description

Technical field [0001] The invention relates to a new type of artificial anal sphincter system, more specifically, to a feedback type artificial anal sphincter system based on percutaneous energy supply. Background technique [0002] Anal incontinence is a common clinical disease. According to statistics, the incidence rate of adults is as high as 2%, and the incidence rate of people over 65 can reach 7%. It not only brings suffering to patients, but also burdens society. [0003] Surgical treatment of anal incontinence includes enterostomy and artificial anal sphincter. A history of enterostomy surgery is the last option for surgical treatment of fecal incontinence. It is an effective way to save lives, but it is a disability and deformity that violates physiology, which greatly affects the quality of life and quality of life of patients. Artificial anal sphincter is the use of artificial organs to treat fecal incontinence. In foreign countries, artificial anal sphincter has been...
