Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an adjustable vaginal dilator for gynecological surgery. Background Art

[0002] Gynecological surgery can be performed in many ways, such as laparotomy, laparoscopic minimally invasive surgery, transvaginal minimally invasive surgery, hysteroscopy, combined hysteroscopy and laparoscopy, etc. There are many specific names for the surgeries, such as the more common ones are artificial abortion, placement or removal of intrauterine contraceptive devices, diagnostic curettage, tubal insufflation, cervical polyps, cervical biopsy, removal of vulvar growths, removal of Bartholin's gland cysts, removal of uterine fibroids, ovarian tumors, etc. At the same time, the vaginal speculum is one of the commonly used medical devices in gynecological vaginal surgery. It is mainly used to dilate the vagina, expose the cervix and vaginal wall, so as to facilitate surgery.

[0003] After searching, it was found that a gynecological surgical vaginal dilator device was mentioned in the application document with publication number CN215129289U. The gynecological surgical vaginal dilator device realizes the vaginal dilator operation through the provided vaginal dilator. When dilating the patient's vagina, the vaginal dilator adjustment and fixing mechanism operates to drive the upper duckbill and the lower duckbill to open and close to realize the vaginal dilator operation on the patient, which is convenient for the doctor to perform subsequent corresponding operations. When the corresponding vaginal dilator position is adjusted according to the location where the vaginal dilator needs to be dilated, the linear adjustment drive mechanism operates to drive the moving seat to drive the vaginal dilator to move in a linear direction, which is convenient for adjusting and positioning the vaginal dilator position. When it is necessary to adjust the corresponding vaginal dilator height, the lifting and adjusting drive mechanism operates to realize the first support plate driving the vaginal dilator to adjust and position in the height direction. When it is necessary to move the vaginal dilator to the desired position for vaginal dilator operation, the moving and adjusting lifting mechanism operates to realize the shock absorption of the vaginal dilator when it moves and the fixed support to the desired position. It is easy to use and has the effect of facilitating positioning and adjustment.

[0004] However, there are still certain deficiencies that need to be improved, as follows: First, the vaginal dilation adjustment and fixing mechanism in the gynecological surgical vaginal dilation device is located in front of the vaginal opening, which may cause certain obstacles to the gynecological surgical operation and is inconvenient to operate; secondly, the expansion pressure of the vaginal dilation adjustment and fixing mechanism in the gynecological surgical vaginal dilation device during operation cannot be clearly seen, which may easily lead to improper vaginal dilation angles and cause damage to the vagina or cervical tissue. Therefore, it is particularly important to improve the existing gynecological surgical vaginal dilation device and design an adjustable vaginal dilator for gynecological surgery to solve the above-mentioned technical defects and improve the overall convenience and safety. Summary of the invention

[0005] The purpose of the present invention is to provide an adjustable vaginal dilator for gynecological surgery. Firstly, through the design of the side adjustment mechanism, two groups of flip adjusters that are symmetrically distributed on the left and right can be respectively located between the lower convex positioning frame and the upper convex flip frame near the two ends, and under the action of the flip adjuster, the upper convex flip frame flips upward, so as to realize vaginal dilation adjustment on both sides of the patient, avoid congestion and obstacles to the patient's vaginal opening, provide a larger surgical operation space, so that the overall gynecological vaginal dilator provides convenience for gynecological vaginal surgery compared with the existing gynecological surgery vaginal dilator. Secondly, through the design of the vaginal dilator, when the upper vaginal dilator mouth expands, the patient's vaginal wall will squeeze the water bag. At this time, the pressure is automatically detected by a micro pressure sensor, and the specific pressure data is displayed by a digital pressure controller. At the same time, the vaginal dilator adjustment is automatically suspended after the pressure limit value is reached to prevent tissue damage to the patient's vagina or cervix due to improper vaginal dilator angle.

[0038] Further, the side adjustment mechanism 4 includes a lower convex positioning frame 41 and an upper convex flip frame 42. The lower convex positioning frame 41 is fixedly mounted on the top surface of the vaginal dilation operating table 2 through a supporting column 43. The upper convex flip frame 42 is movably mounted on the top surface of the lower convex positioning frame 41 through two groups of flip adjusters 44 that are symmetrically distributed on the left and right. The lower convex positioning frame 41 and the upper convex flip frame 42 both include a central frame body 45. Both ends of the central frame body 45 are provided with a vertically arranged side frame body 46. The end of the side frame body 46 away from the central frame body 45 is provided with an end seat 47. The side frame body 46 and The central frame 45, the end seat 47 and the side frame 46 are all slidably connected by adjusting the slide bar 48. The top surface of the central frame 45 near both ends and the top surface of the side frame 46 near one end of the end seat 47 are all spirally installed with locking bolts 49. Through the design of the central frame 45, the side frame 46, the end seat 47 and the adjusting slide bar 48, the lower convex positioning frame 41 and the upper convex flip frame 42 can be adjusted by sliding longitudinally and transversely according to the distance between the patient's vaginal opening and the whole body and the patient's body width, and after adjustment, the locking bolts 49 are used to spirally lock and position, making the whole more practical.

[0039] The flip adjuster 44 is used to adjust the flip angle of the upper convex flip frame 42;

[0040] Furthermore, two groups of flip regulators 44 that are symmetrically distributed on the left and right are respectively located between the lower convex positioning frame 41 and the upper convex flip frame 42 near the two ends. Any one of the two groups of flip regulators 44 that are symmetrically distributed on the left and right includes a lower fixed seat 441 fixedly installed on the top surface of the lower convex positioning frame 41, an upper rotating seat 442 fixedly installed on the bottom surface of the upper convex flip frame 42, a gear transmission box 443, and an adjustment transmission assembly 444. The upper rotating seat 442 is located on both sides of the lower fixed seat 441, which can make the rotation process more stable and reliable. The two groups of flip regulators 44 that are symmetrically distributed on the left and right are respectively located between the lower convex positioning frame 41 and the upper convex flip frame 42 near the two ends, so that the flip regulator 44 can be adjusted to dilate the vagina on both sides of the patient, avoiding congestion and obstacles to the patient's vaginal opening, providing a larger surgical operation space, and thus making the overall gynecological vaginal dilation device more convenient for gynecological vaginal surgery than the existing gynecological surgery.

[0041] Furthermore, the gear transmission box 443 is fixedly installed on the side of the lower fixed seat 441 away from the patient through the mounting seat 4431, and the adjusting transmission assembly 444 includes a transmission rotating shaft 4441 installed through the lower fixed seat 441 and the center of the upper rotating seat 442, and the transmission rotating shaft 4441 can be supported by the design of the lower fixed seat 441, the transmission rotating shaft 4441 is rotatably connected to the lower fixed seat 441, and the transmission rotating shaft 4441 is fixedly connected to the upper rotating seat 442, and the transmission rotating shaft 4441 is fixedly connected to the large driven gear 4443 at one end of the transmission rotating shaft 4441 close to the gear transmission box 443 through the connecting shaft 4442, and the top surface of the large driven gear 4443 is meshedly connected with the small driving gear 4444, and the end of the small driving gear 4444 away from the transmission rotating shaft 4441 is provided with a stepping motor 4445, and the stepping motor 4445 and the small driving gear 4444 are connected by a key , and the stepper motor 4445 and the digital pressure controller 3 are electrically connected through a wire, and the stepper motor 4445 is fixedly installed on the side of the gear transmission box 443 away from the patient through the motor seat 4446. During the vaginal dilation during the operation, under the drive of the digital pressure controller 3, the stepper motor 4445 starts to work and drives the small driving gear 4444 to start rotating, and under its action, the large driven gear 4443 rotates accordingly, at this time, the transmission rotating shaft 4441 rotates at the center of the lower fixed seat 441, and drives the upper convex turning frame 42 to turn around the transmission rotating shaft 4441 through the upper rotating seat 442, at this time, the vaginal dilator 5 gradually opens and expands the patient's vagina, and the torque can be increased by adjusting the design of the transmission component 444 by using the cooperation of the small driving gear 4444 and the large driven gear 4443 to achieve the effect of deceleration, so as to avoid the vaginal dilation speed being too fast and causing damage to the patient's vagina;

[0042] The large driven gear 4443 and the small driving gear 4444 are both located inside the gear transmission box 443. The design of the gear transmission box 443 facilitates the installation and fixation of the stepper motor 4445 on the one hand, and can protect the large driven gear 4443 and the small driving gear 4444 from being contaminated on the other hand.

[0043] The vaginal dilator 5 includes a lower vaginal dilator nozzle 51 and an upper vaginal dilator nozzle 52 which are symmetrically distributed in an upper and lower manner. A water bag 521 is fixedly installed on the top surface of the upper vaginal dilator nozzle 52 near one end of the patient's body. A micro pressure sensor 522 is fixedly installed between the water bag 521 and the top surface of the upper vaginal dilator nozzle 52. The micro pressure sensor 522 is used to automatically detect the pressure value of the vaginal wall on the water bag 521. The micro pressure sensor 522 and the digital pressure controller 3 are electrically connected through a connecting wire 523. When the upper vaginal dilator nozzle 52 expands, the patient's vaginal wall will squeeze the water bag 521. At this time, the pressure is automatically detected by the micro pressure sensor 522, and the specific pressure data is displayed by the digital pressure controller 3. At the same time, the vaginal dilator adjustment is automatically suspended after the pressure limit value is reached to prevent tissue damage to the patient's vagina or cervix due to improper vaginal dilator angle, thereby providing safety for gynecological vaginal surgery as a whole compared with existing gynecological surgical vaginal dilator devices. The design of the water bag 521 is convenient for detecting the pressure of the vaginal wall on the one hand, and can increase the patient's comfort and enhance the experience on the other hand.

[0044] Among them, both ends of the lower vaginal expansion nozzle 51 and the upper vaginal expansion nozzle 52 are processed with arc chamfers, which facilitates the vaginal expansion device 5 to enter the patient's vagina and effectively greatly reduces the mechanical damage to the patient's vagina;

[0045] Furthermore, the lower convex positioning frame 41 corresponds to the lower vaginal expansion nozzle 51, and the upper convex flip frame 42 corresponds to the upper vaginal expansion nozzle 52, and the lower vaginal expansion nozzle 51 and the upper vaginal expansion nozzle 52 are respectively fixedly installed at the center of one side of the adjacent central frame body 45 close to the patient's body, which can make the operation space larger and facilitate the longitudinal and lateral adjustment of the lower convex positioning frame 41 and the upper convex flip frame 42;

[0046] Furthermore, locking universal wheels 11 are movably installed at the four corners of the bottom of the equipment cart 1, and an electric telescopic rod 12 acting on the vaginal dilation operating table 2 is movably installed on the top surface of the equipment cart 1, and the electric telescopic rod 12 is electrically connected to the digital pressure controller 3. A telescopic frame 13 is movably installed between the top surface of the equipment cart 1 and the bottom surface of the vaginal dilation operating table 2, and a push handle 14 is fixedly installed on one side of the equipment cart 1. Under the action of the electric telescopic rod 12, the vaginal dilation operating table 2 rises and falls accordingly, so as to facilitate automatic adjustment according to the surgical height of the patient's vaginal opening, and the design of the telescopic frame 13 can make the vaginal dilation operating table 2 automatically extend and retract during the lifting process, which is beneficial to the lifting stability of the vaginal dilation operating table 2 and prevents shaking. At the same time, the locking universal wheels 11 and the push handle 14 can make the overall equipment easy to move and position. At the same time, the design of the vaginal dilation operating table 2 is convenient for the installation and fixation of the contralateral adjustment mechanism 4 and the vaginal dilator 5 on the one hand, and provides an operating table for gynecological vaginal surgery on the other hand;

[0047] In this embodiment, the implementation scenario is specifically as follows: in actual use, the entire device can be moved to a position close to the patient's vagina by means of the locking universal wheel 11 and the push handle 14, and the electric telescopic rod 12 is activated to extend and retract according to the surgical height of the patient's vaginal opening, and under its action, the vaginal dilation operating table 2 is raised and lowered accordingly until the vaginal dilator 5 is aligned with the patient's vaginal opening, and then the lower convex positioning frame 41 and the upper convex flip frame 42 are adjusted to slide and stretch synchronously in the longitudinal and transverse directions according to the distance between the patient's vaginal opening and the entire device and the patient's body width, and after adjustment, the locking bolt 49 is used to perform spiral locking and positioning, and then the vaginal dilator 5 is pushed into the patient's vagina, and then the equipment vehicle 1 is locked, and then, driven by the digital pressure controller 3, the step tightening motor 4445 starts to work, and drives the small driving gear 4444 to start rotating, and under its action, the large driven gear 4443 rotates accordingly, and at this time, the transmission rotating shaft 4441 is on the lower fixed seat 4 41 rotates at the center of the circle, and drives the upper convex flip frame 42 to flip around the transmission rotating shaft 4441 as the axis through the upper rotating seat 442, and the flip regulator 44 performs vaginal dilation adjustment on both sides of the patient to avoid congestion and obstruction to the patient's vaginal opening, providing a larger surgical operation space, so that the overall gynecological vaginal dilation device provides convenience for gynecological vaginal surgery compared with the existing gynecological surgery vaginal dilation device. At this time, the vaginal dilator 5 gradually opens and dilates the patient's vagina. When the upper vaginal dilation mouth 52 expands, the patient's vaginal wall will squeeze the water bag 521. At this time, the pressure is automatically detected by the micro pressure sensor 522, and the specific pressure data is displayed by the digital pressure controller 3. At the same time, the vaginal dilation adjustment is automatically suspended after the pressure limit value is reached to prevent tissue damage to the patient's vagina or cervix due to improper vaginal dilation angle. Compared with the existing gynecological surgery vaginal dilation device, the present invention provides gynecological vaginal surgery with convenience and safety of operation.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
