Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a visual rectal hemorrhoid artery ligation and suspension ultrasonic Doppler detection device. Background Technique

[0002] Rectal hemorrhoid artery ligation and suspension surgery is a minimally invasive surgical method for treating hemorrhoids. The formation of hemorrhoids is closely related to the blood supply of the rectal hemorrhoid artery. By ligating the hemorrhoid artery, the blood perfusion of the hemorrhoid nucleus can be reduced. After the hemorrhoid nucleus loses its rich blood supply, it will gradually shrink and become smaller. During the operation, an auxiliary device is usually required to enable the doctor to clearly see the affected area. An ultrasonic Doppler detection device is an instrument that uses ultrasonic waves and the Doppler effect to detect moving objects (such as red blood cells in blood flow). It is mainly based on the principle of ultrasonic wave reflection. When ultrasonic waves are emitted into human tissues, reflections will occur when encountering interfaces with different acoustic impedances. When ultrasonic waves encounter moving objects such as red blood cells in blood flow, a change in frequency will occur, which is the Doppler effect. The device obtains information such as blood flow velocity, direction, and blood vessel position by receiving and analyzing the change in the frequency of the reflected ultrasonic waves. This device can help doctors determine the position of the rectal hemorrhoid artery.

[0003] Existing auxiliary devices are widely used. However, the observation port of the existing auxiliary device is usually located at the bottom end of the insertion tube, resulting in inconvenient observation and operation for doctors. The connection between the insertion tube and the auxiliary device usually uses snap connection or threaded connection, and this connection method is not firm enough and is prone to falling off. Moreover, the existing auxiliary device has a lower temperature and a relatively dry outer surface. During the operation, doctors need to manually apply lubricant before operation. The low-temperature lubricant may drip on the patient, resulting in a poor surgical experience for the patient. Therefore, in view of the above problems, a visual rectal hemorrhoid artery ligation and suspension ultrasonic Doppler detection device is proposed. Summary of the Invention

By providing the heating component 8, the first sponge cylinder 81, the threaded cylinder 82, the heat conduction column 83, the external thread 84, the heating wire 85, the heating device 86, the lubrication component 9, the second sponge cylinder 91, the lubrication cylinder 92, the oil inlet hole 93, the filling cylinder 94, and the support base 95, before using the device, the detection body 7 is inserted into the inner side of the second sponge cylinder 91, and the first sponge cylinder 81 is inserted into the inner side of the insertion cylinder 72. Next, lubricating oil is injected into the inner side of the filling cylinder 94. The lubricating oil enters the inner side of the second sponge cylinder 91 through the oil inlet hole 93 and adheres to the outer sides of the insertion cylinder 72 and the baffle 74. At this time, the heating device 86 is started to heat the insertion cylinder 72 to a suitable temperature. This design can evenly apply the lubricating oil on the outer side of the insertion cylinder 72 without manual application by the doctor, and can heat the lubricating oil and the insertion cylinder 72 to provide a better surgical experience for the patient.

[0032] Workflow: First, install the detection body 7. Insert the fixing ring 712 into the inner side of the ring groove 4 at the bottom end of the ultrasonic detection device 1, and make the clamping block 711 insert into the inner side of the clamping groove 5 and engage with the clamping groove 5. The threaded groove 6 is horizontally aligned with the round hole 713. The engagement of the clamping block 711 with the clamping groove 5 can initially fix the detection body 7. Subsequently, insert the screw 714 into the inner side of the round hole 713 and screw the screw 714 into the inner side of the threaded groove 6, then the installation of the detection body 7 can be completed. The setting of the installation component 71 makes the installation of the detection body 7 more convenient and firm, avoiding the detection body 7 from falling during use. Before use, power on the device, place the support base 95 on a plane, insert the second sponge cylinder 91 into the inner side of the lubricating cylinder 92 at the top end of the support base 95, and insert the detection body 7 into the inner side of the second sponge cylinder 91, so that the inner and outer sides of the second sponge cylinder 91 are respectively in close contact with the outer side of the insertion cylinder 72 and the inner side of the lubricating cylinder 92. Subsequently, insert the heat conduction column 83 into the inner sides of the threaded cylinder 82 and the first sponge cylinder 81, screw the threaded cylinder 82 onto the outer side of the external thread 84, and insert the first sponge cylinder 81 into the inner side of the insertion cylinder 72, so that the inner and outer sides of the first sponge cylinder 81 are respectively in close contact with the outer side of the heat conduction column 83 and the inner side of the insertion cylinder 72. Next, inject lubricating oil into the inner side of the filling cylinder 94. The lubricating oil in the inner side of the filling cylinder 94 enters the inner side of the second sponge cylinder 91 in the lubricating cylinder 92 through the oil inlet hole 93. The lubricating oil continuously seeps into the inside of the second sponge cylinder 91 due to gravity and adheres to the outer sides of the insertion cylinder 72 and the baffle 74. At this time, start the heating device 86. The heating device 86 heats the heat conduction column 83 through the heating wire 85. The heat conduction column 83 transfers the heat to the insertion cylinder 72, heating the insertion cylinder 72 to an appropriate temperature. After the heating of the insertion cylinder 72 is completed, take out the first sponge cylinder 81 from the inner side of the insertion cylinder 72, and take out the insertion cylinder 72 from the inner side of the second sponge cylinder 91. At this time, the lubricating oil is evenly smeared on the outer side of the insertion cylinder 72, and the temperature is close to the human body temperature. The settings of the heating component 8 and the lubricating component 9 can make the lubricating oil evenly smeared on the outer side of the insertion cylinder 72 without manual smearing by the doctor, and can heat the lubricating oil and the insertion cylinder 72, making the patient's surgical experience better. The doctor can hold the ultrasonic detection device 1 and insert the insertion cylinder 72 into the patient's body, and turn on the operation display screen 2. At this time, the ultrasonic probe 75 records the situation inside the patient's body and displays it through the operation display screen 2. Observe the internal structure of the rectum through the operation display screen 2 during the insertion process. According to the ultrasonic image and Doppler signal, gradually adjust the position and angle of the ultrasonic probe 75 to find the hemorrhoidal artery until the position of the baffle 74 is aligned with the position of the rectal hemorrhoidal artery. Next, pull out the baffle 74 inside the retaining groove 73, and the doctor can insert the tool into the inner side of the groove 3 to ligate and suspend the rectal hemorrhoidal artery at the retaining groove 73, reducing the blood supply to the hemorrhoid nucleus and causing the hemorrhoid nucleus to atrophy. At the same time, through the suspension effect, improve the prolapse of the rectal mucosa. The designs of the groove 3 and the retaining groove 73 make the doctor's observation and operation more convenient, improving the surgical efficiency. With the help of ultrasonic Doppler technology, the position of the hemorrhoidal artery can be accurately found.This avoids the problems of damaging surrounding tissues that may be caused by blind ligation in traditional surgery. The operation can be completed at this point. After the operation is completed, the ligation effect is checked again through the ultrasonic probe 75 to observe whether the blood flow of the hemorrhoidal artery is effectively blocked and whether the position of the rectal mucosa is improved. Next, the ultrasonic detection device 1 and the operation display screen 2 are turned off, the insert 72 is pulled out of the patient's body, the screw 714 is unscrewed from the inside of the threaded groove 6, and the detection body 7 is removed to disengage the fixing ring 712 from the ring groove 4, thereby cleaning and disinfecting the ultrasonic detection device 1 and the insert 72 respectively to ensure that each component is in a sterile state and does not affect the next use of the device. After using the heating component 8 and the lubricating component 9 for a period of time, the first sponge tube 81 and the second sponge tube 91 can be taken out and replaced, and each component on the heating component 8 and the lubricating component 9 is disinfected to avoid bacteria from being generated when the device is used for too long.
