Description

Technical Field

[0001] The utility model relates to the technical field of hemorrhoid treatment equipment, and particularly relates to a hemorrhoid treatment equipment with traceable diagnostic results. Background Art

[0002] Hemorrhoids are a common anorectal disease. At present, surgical treatments are mainly carried out through procedures such as circular stapled hemorrhoidectomy, hemorrhoidectomy, and hemorrhoidal artery ligation. However, due to local vein compression, blood reflux is blocked, and the mucosal tissue of the hemorrhoidal vein becomes loose, causing dilation and tortuosity, resulting in recurrence of hemorrhoids. At present, the detection and surgical treatment methods for hemorrhoids mainly focus on diagnosing the state of hemorrhoids and surgical operations. There is no technical solution specifically for recording the positions of hemorrhoidal arteries, hemorrhoid nuclei and other hemorrhoid symptoms and signs in the anorectal canal, which causes certain difficulties in verifying the postoperative treatment effect and judging the recurrence of hemorrhoids. Since there are certain differences between recurrent hemorrhoids after surgical treatment and newly formed hemorrhoids, due to previous treatment, the recurrent hemorrhoid nuclei may have more obvious symptoms due to the formation of scar tissue, which may increase the risk of infection, scar formation or other complications. Moreover, the recurrent hemorrhoid nuclei may cause the surrounding tissues to harden due to previous treatment and healing processes, which may increase the difficulty of re-treatment. In addition, since previous treatment may have affected the local blood circulation and healing ability, the recurrent hemorrhoid nuclei may take longer to heal, so there are differences in the observation and treatment after re-surgical treatment of recurrent hemorrhoids compared with the treatment of newly formed hemorrhoids. Even for recurrent hemorrhoid nuclei, different treatment strategies may need to be considered. In summary, it is necessary to rely on surgical instruments to record the location of hemorrhoid occurrence for judging the postoperative recovery effect and recurrence situation of hemorrhoid treatment.

One end of the sampling resistor is connected to an external battery, and the other end is connected to the GPIO pin of the low-power microcontroller.

The DC / DC converter converts the voltage of the external battery into a rated voltage of 3.3V to supply the digital power supply voltage input pin and the analog power supply voltage input pin.

[0013] The hemorrhoid treatment device with traceable diagnosis results provided by the present utility model has the following beneficial effects compared with other existing products:

[0014] Based on the traditional handheld hemorrhoid diagnosis and treatment instrument, the hemorrhoid treatment device provided by the present utility model further adds a rotary encoding unit. The CPU processor senses and controls the rotation angle of the rotary encoder as the handheld diagnosis and treatment instrument rotates in the anal canal and rectum, and records the position information of the target angle and the blood flow-related information at this position in the CPU processor, providing a basic guarantee for the CPU processor to implement subsequent functions such as visual display and remote recording and printing of these data. Moreover, through the rotary encoding recording function of the present utility model, the position of the patient with hemorrhoids and the position of the hemorrhoidal artery ligation operation can be recorded, for doctors to observe the subsequent postoperative healing situation, as well as to distinguish the newly emerging hemorrhoids and the historical hemorrhoids with postoperative recurrence that may occur subsequently, so as to assist doctors in adopting more reasonable treatment means.

The hemorrhoid treatment device provided in the present utility model includes an ultrasonic detection unit and a rotary encoding unit. The ultrasonic detection unit includes a CPU processor for controlling the emission of ultrasonic waves and analyzing and processing the echo signals to detect blood flow information. The CPU processor controls the ultrasonic wave emission of the ultrasonic detector, as well as the reception and filtering processing of the echo signals. In the present utility model, the selection of other ultrasonic transducers in the ultrasonic detection unit and the specific control method of the CPU processor for the transducer are not specifically limited and can be controlled and implemented in a manner well-known to those skilled in the art.

The CPU processor in the present utility model is connected to an undervoltage detection unit for detecting the voltage supplied by an external battery / external power supply to the CPU processor, so as to avoid affecting the normal use of the hemorrhoid treatment device due to the supplied voltage not meeting the normal operation of the processor; among them, the upper limit threshold of the undervoltage detection circuit is not specially limited, and generally it can be used as long as it is lower than 12V; the lower limit threshold of the voltage of the undervoltage detection circuit is not lower than 5V, and for example, it can be 5.1V, 5.2V, 5.3V, 5.4V, 5.5V, 5.6V, 5.7V, 5.8V, 5.9V, 6.0V, etc.; the undervoltage detection circuit therein is connected through the GPIO pin of the CPU processor.
