An intelligent laparoscopic limiter for preventing uterine perforation

Abstract

The present invention discloses an intelligent laparoscope limiter for preventing uterine perforation. The electric push rod pushes the limit plate to move in the left and right directions, which is conducive to adjusting the position of the limit plate to achieve limiting of different depths of the laparoscope. The infrared ranging sensor can detect the spacing position of the detection column in real time. Since the detection column can be driven by the limit plate, the position information of the limit plate can be obtained by detecting the position of the detection column, which is convenient for precise control. The visual scanning of the visual sensor can be conducive to judging the spacing between the installation sleeve and the inner wall of the patient's uterine cavity. When the spacing size is within a preset detection safety range, the microprocessor chip can synchronously send a high level to the alarm and the electric push rod, which is conducive to the alarm sounding an alarm to remind medical staff to stop operating. At the same time, the electric push rod can also push the limit plate to extend, which is conducive to the limit plate being attached to the outside of the patient's vaginal opening. The limit plate can prevent the laparoscope from penetrating into the uterine cavity again under the push of the medical staff's hands.

[0002] Laparoscopes are important instruments in gynecological surgery, used for examination and treatment within the uterine cavity. Typically, a hysteroscope consists of a lens that can clearly see the inner wall of the uterine cavity and a cavity.

[0003] Based on the above, a common problem in clinical laparoscopic examinations and other operations is that when the laparoscope penetrates deep into the uterine cavity, due to the lack of warning and limiting mechanisms in the laparoscope, it is easy for the laparoscope port to touch the inner wall of the uterine cavity, and medical staff cannot predict in advance, thus causing damage to the patient's uterine cavity, and even the risk of uterine perforation. Therefore, in view of the above defects, it is necessary to design an intelligent laparoscope limiter to prevent uterine perforation. Summary of the Invention

[0025] The following specific implementation will be further described in conjunction with the above drawings. DETAILED DESCRIPTION

[0026] In the following text, numerous specific details are set forth in order to provide a thorough understanding of the concepts that form the basis of the described embodiments; however, it will be apparent to those skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well-known processing steps are not specifically described.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, an intelligent laparoscope stopper for preventing uterine perforation includes a laparoscope 1, a ferrule 2, a connecting plate 3, an alarm 4, an electric push rod 5, a detection tube 6, an infrared ranging sensor 7, a limit plate 8, a detection column 9, a mounting sleeve 10, a visual sensor 11, a microprocessor chip 12, a fastening bolt 201, a waterproof wire 202, an anti-pressure cushion 801, an avoidance hole 802, a mounting slot 1001, and an avoidance hole 1002;

[0028] In one embodiment, the ferrule 2 can be stuck on the outer wall of the laparoscope 1. By rotating the fastening bolt 201, the ferrule 2 can be locked, which is conducive to the firm connection between the ferrule 2 and the laparoscope 1, and is convenient for subsequent linkage with the laparoscope 1;

[0029] In one embodiment, the connecting plate 3 can connect the electric push rod 5, which is beneficial for the electric push rod 5 to push the limit plate 8 to move in the left and right directions, and is beneficial for adjusting the position of the limit plate 8 to achieve different depth limits of the laparoscope 1;

[0030] In one embodiment, the infrared distance measuring sensor 7 on the right side of the detection cylinder 6 can detect the spacing position of the detection column 9 in real time. Since the detection column 9 can be driven by the limit plate 8, the position information of the limit plate 8 can be obtained by detecting the position of the detection column 9, which facilitates precise control.

[0031] In one embodiment, the mounting groove 1001 on the inner wall of the mounting sleeve 10 can be threadedly rotated with the left port of the laparoscope 1, thereby achieving a clever combination of the mounting sleeve 10. When the left port of the laparoscope 1 penetrates into the inner wall of the patient's uterine cavity, the visual scanning of a number of visual sensors 11 on the mounting sleeve 10 can facilitate the determination of the distance between the mounting sleeve 10 and the inner wall of the patient's uterine cavity.

[0032] In one embodiment, the microprocessor chip 12 can receive the spacing size of the inner wall tissue of the uterine cavity detected by the visual sensor 11 in real time. When the spacing size is within the preset detection safety range, the microprocessor chip 12 can synchronously send a high level to the alarm 4 and the electric push rod 5, which is conducive to the alarm 4 to issue an alarm sound in time, so as to remind the medical staff to stop the excessively deep operation. At the same time, the electric push rod 5 can also push the limit plate 8 to drive the anti-pressure cushion 801 to extend, which is conducive to the anti-pressure cushion 801 on the limit plate 8 to fit the outside of the patient's vaginal opening. Through the limiting purpose of the limit plate 8 and the anti-pressure cushion 801, the problem of the laparoscope 1 penetrating into the patient's uterine cavity again under the push of the medical staff's hands can be avoided.

[0033] In one embodiment, the waterproof wire 202 can electrically connect the alarm 4, the electric push rod 5, the infrared distance sensor 7, the visual sensor 11 and the microprocessor chip 12 respectively, which is beneficial to the transmission of current and signals and convenient for operation and control;

[0034] Specifically, before the operation, the medical staff rotates and docks the mounting sleeve 10 on the device with the port of the laparoscope 1 in the prior art, and then rotates the fastening bolt 201 on the ferrule 2 to fasten the ferrule 2 to the outer wall of the laparoscope 1; during the operation, the medical staff holds the right side of the laparoscope 1 and penetrates the left port of the laparoscope 1 into the inner wall of the patient's uterine cavity. At the same time, the electric push rod 5 and the limit plate 8 are always located outside the patient's body. When the port of the laparoscope 1 is in the process of deepening the operation, the visual sensor 11 detects that the distance to the inner wall of the uterine cavity is close to the safety upper limit, and the microprocessor chip 12 can trigger the alarm 4 to turn on, which is used to remind the medical staff to operate in time. Adjustment, the synchronous electric push rod 5 quickly pushes the limit plate 8 forward, which is beneficial for the limit plate 8 to drive the anti-pressure cushion 801 to move quickly and touch the skin outside the patient's vagina. Because the anti-pressure cushion 801 is made of soft material, it can make soft contact with the patient's skin to avoid hard contact and damage to the patient's skin. At this time, with the help of the resistance of the reaction force of the limit plate 8 at the patient's vaginal opening, the laparoscope 1 can be prevented from continuing to penetrate into the patient's uterine cavity under the operation of medical staff, thereby realizing the cessation of the in-depth operation, and then preventing the occurrence of uterine cavity perforation problems, which greatly avoids the risk of inaccurate operation caused by medical staff's misoperation, slow reaction, etc., and increases the risk of safety hazards.

[0035] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by ordinary technicians in this field based on the above-mentioned concept without creative work are all within the scope of protection of the present invention.
