Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an integrated hysteroscope. BACKGROUND

[0002] A hysteroscope is an advanced gynecological diagnostic and treatment device that integrates a hysteroscope, a camera system, a display system, an illumination system, and surgical instruments. It can be used to examine and treat various diseases in the uterine cavity. Compared with traditional hysteroscopy, the hysteroscope has many advantages. First, it uses a high-definition camera system and a high-quality display screen, which can clearly display the lesions in the uterine cavity, improving the accuracy and reliability of diagnosis. Second, the surgical instruments of the hysteroscope are well designed and easy to operate, which can quickly complete the surgical operation and reduce the operation time and postoperative recovery time. In addition, the hysteroscope has an integrated design, which is convenient for doctors and nurses to operate and maintain, and reduces the use and maintenance costs. In gynecological diagnosis and treatment, the hysteroscope has a wide range of applications. It can be used to examine and treat endometriosis, intrauterine adhesion, uterine fibroids, and uterine septum. In addition, the hysteroscope can also be used for pre-IVF uterine cavity examination and treatment, improving the success rate of IVF.

[0003] The existing social existence of delayed childbearing age, environmental pollution, unhealthy lifestyle, lack of reproductive health protection, etc. leads to the increase of infertility rate, and the unproduced uterine mouth is smaller than the produced uterine mouth. In hysteroscopic surgery, the dilatation device needs to expand the cervical orifice, which will cause certain damage to the cervix. If the damage is large, it may cause some problems during future childbirth, such as cervical relaxation leading to spontaneous abortion. In hysteroscopic surgery, it is necessary to inject uterine distension fluid into the uterine cavity, and the size of the liquid inlet channel will affect the uterine distension operation time and the pressure difference between the uterine distension machine and the uterine cavity. A larger pressure difference will increase the risk of surgery. In addition, due to the complex environment of the uterine cavity and the presence of many tissues, especially the integrity of the endometrium, which is related to the reproductive function of the patient, hysteroscopic surgery may cause damage to the endometrium to some extent, which may affect the reproductive function. In order to prevent the structure of the hysteroscope from colliding with the tissue and causing damage, and when injecting uterine distension fluid into the uterine cavity, how to automatically adjust the flow rate of the liquid inlet according to the pressure in the uterine cavity to achieve adaptive control of the pressure difference in the uterine cavity.

[0010] As a preferred solution of the present invention, one end of the connecting tube passes through the handle shell and extends to the inner cavity of the handle shell, and an electric-controlled flow valve is installed. A controller is installed on the outer wall of the electric-controlled flow valve. One end of the electric-controlled flow valve is installed with a conduit, and a fixed block is installed on the outer wall of the conduit. The fixed block is embedded in the inner wall of the handle shell.

When the uterine insertion end is inserted into the uterine cavity, the same principle is applied, so that one end of the uterine insertion end drives the connecting spring to move, so that the connecting spring is compressed in the inner cavity of the limit shell, so that the uterine insertion end has a certain stretching space to prevent the uterine insertion end from squeezing and moving on the uterine cavity, causing scratching and damage. The practicality of the device is better, thereby solving the problem that the environment of the uterine cavity is complex and there are many tissues, especially the integrity of the endometrium will be related to the patient's reproductive function. Hysteroscopic surgery may cause a certain degree of damage to the endometrium, which may affect the reproductive function. In order to prevent the structure of the hysteroscope from colliding with the tissue and causing damage.

[0019] When the uterine end is inserted into the uterine cavity, the hydraulic sensor generates data according to the pressure of the distending fluid based on the liquid pressure in the uterine cavity, and the hydraulic sensor generates an electrical signal which is transmitted to the controller through a wire. When the set parameter range is reached, the controller controls the electric flow valve to operate, and the electric flow valve controls the liquid flow of the catheter, so that the amount of liquid entering the uterine cavity is adjusted to facilitate the operation of the device and improve the practicality of the device, thereby solving the problem of how to automatically adjust the flow rate of the liquid according to the pressure of the uterine cavity when injecting distending fluid into the uterine cavity, and achieving the goal of adaptively controlling the pressure difference in the uterus.

The limit spring 503 is located on one side of the connecting spring 505, and the connecting spring 505 is located in the inner cavity of the limit shell 501, and one end of the connecting spring 505 passes through the inner cavity of the vaginal insertion end 6 and is connected to the uterine insertion end 7.

[0032] Wherein, the optical imaging module 805 includes an objective lens, a prism and an optical imaging system, the optical imaging system contains a camera and the camera can be turned to an angle, the objective lens is tilted at an angle and the prism is tilted relative to the objective lens, under the action of the prism, the optical imaging system has an angle, the inspection range is increased, and the tilt angle β of the objective lens ranges between 15° and 35°, the fixed block 12 is provided with two groups and is located on the inner wall of the handle shell 1 respectively, the catheter 11 is provided with two groups and is located at the port of the backflow channel shell 802 and the liquid inlet channel A 808 respectively, the connecting pipe 2 is provided with two groups and is located on the opposite outer walls of the handle shell 1 respectively, the controller 10 is connected with the electric control flow valve 9 and the hydraulic sensor 812 through wires respectively and the connection mode is electrically connected, so that the device is powered on, the plug-in interface 4 is provided with two groups and is located on the outer wall of the manual valve 3 respectively, one side of the plug-in interface 4 carries out liquid inlet, and the other side of the plug-in interface 4 carries out liquid outlet;

[0034] When the integrated hysteroscope of this scheme is working, an insertion vagina end 6 is installed at one end of the limiting component 5, and an insertion uterine end 7 is slidably connected to the port of the insertion vagina end 6. Under the action of the insertion head end component 8, since the insertion uterine end 7 is located at the port of the insertion vagina end 6 and the diameter of the insertion uterine end 7 is thinner than the insertion vagina end 6, the front end of the insertion uterine end 7 is thin and the rear end of the insertion vagina end 6 is thick. The front end acts in the uterus and the rear end acts in the vagina. While reducing the damage to the cervical opening, the strength of the hysteroscope is increased, making the use effect of the device better. At the same time, a connecting tube 2 is provided on the outer wall of the handle shell 1, and a manual valve 3 is installed at one end of the connecting tube 2. Under the action of the plug-in interface 4, the plug-in interface 4 is connected to the liquid outlet of the external syringe, so that the uterine distension fluid flows into the inner cavity of the connecting tube 2 and is inserted into the special-shaped shell. The inner wall of the body 801 is respectively provided with a liquid inlet channel A808, a liquid inlet channel B809 and a liquid inlet channel C810, so that the uterine distension fluid flows into the inner cavity of the device through the catheter 11, and then the uterine distension fluid flows into the inner cavity of the special-shaped shell 801 through the gap, which can effectively increase the liquid inlet flow rate. Then, an optical imaging shell 804 is provided on the inner wall of the special-shaped shell 801, and an optical imaging module 805 is provided at the port of the optical imaging shell 804. The optical imaging shell 804 is provided with a light guide port A806 and a light guide port B807 on the opposite inner walls.

[0035] By rationally arranging the position of the optical imaging module 805, the objective lens has a certain angle and the field of view is more reasonable. According to the structure of the uterus, the diameters of the vaginal insertion end 6 and the uterine insertion end 7 are rationally arranged, thereby increasing the performance and strength of the endoscope. All the space in the special-shaped shell 801 except the instrument channel shell 803 and the optical imaging shell 804 is used as the liquid inlet channel space. While ensuring the liquid inlet flow rate, the diameter of the insertion part is reduced and the damage to the cervical opening is reduced, thereby solving the problem that during hysteroscopic surgery, the dilator needs to dilate the cervical opening, which will cause certain damage to the cervix in this link. If the damage is large, it may cause some problems during future childbearing, such as cervical relaxation leading to spontaneous abortion. At the same time, during hysteroscopic surgery, uterine distension fluid needs to be injected into the uterine cavity, and the size of the liquid inlet channel will affect the time of the uterine distension operation and the pressure difference between the dilator and the uterine cavity, and a large pressure difference will affect the problem of surgical risk.

[0036] When the vaginal insertion end 6 is inserted into the cavity, the limiting shell 501 is slidably connected to the port of the handle shell 1, one end of the limiting shell 501 is connected to the vaginal insertion end 6, a limiting block 502 is installed on the outer wall of the limiting shell 501, and a limiting spring 503 is installed on the outer wall of the limiting block 502. One end of the limiting spring 503 is connected to the inner wall of the handle shell 1. When the vaginal insertion end 6 touches the inner wall of the inner cavity, the vaginal insertion end 6 is subjected to an extrusion force, so that the vaginal insertion end 6 drives the limiting shell 501 to slide at the port of the handle shell 1, so that the limiting shell 501 drives the limiting block 502 to move to one side, and at the same time, the limiting block 502 drives the limiting spring 503 to move, so that the limiting spring 503 is stretched, so that the vaginal insertion end 6 has a certain stretching space to prevent the vaginal insertion end 6 from squeezing and moving on the inner wall of the inner cavity, causing scratches and damage. A positioning block 504 is installed on the inner wall of the limiting shell 501, and a connecting spring 505 is installed on the inner wall of the positioning block 504. One end of the connecting spring 505 penetrates the inner cavity of the vaginal end 6 and is connected to the uterine end 7. When the uterine end 7 is inserted into the uterine cavity, the same principle as above is used to drive one end of the uterine end 7 to move, so that the connecting spring 505 is compressed in the inner cavity of the limiting shell 501, so that the uterine end 7 has a certain stretching space to prevent the uterine end 7 from squeezing and moving on the uterine cavity, causing scratch damage. The practicality of the device is better, thereby solving the problem that the environment of the uterine cavity is complex and there are many tissues, especially the integrity of the endometrium will be related to the patient's reproductive function. Hysteroscopic surgery may cause a certain degree of damage to the endometrium, which may affect the reproductive function. In order to prevent the structure of the hysteroscope from colliding with the tissue and causing damage.

[0037] Under the action of the hydraulic sensor 812 installed on the inner wall of the special-shaped shell 801, when the uterine end 7 is inserted into the uterine cavity, the hydraulic sensor 812 generates data according to the pressure of the distending fluid based on the liquid pressure in the uterine cavity, so that the hydraulic sensor 812 generates an electrical signal which is transmitted to the controller 10 through a wire. When the set parameter range is reached, the controller 10 controls the electric control flow valve 9 to operate, so that the electric control flow valve 9 controls the liquid flow of the catheter 11, and adjusts the amount of liquid entering the uterine cavity, so as to facilitate the operation of the device and improve the practicality of the device, thereby solving the problem of how to automatically adjust the flow rate of the liquid according to the pressure of the uterine cavity when injecting distending fluid into the uterine cavity, and achieving the goal of adaptively controlling the pressure difference in the uterus.
