Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a device for lifting the uterus in gynecological surgery. Background Technology
[0002] A uterine traction device for gynecological surgery is a specialized instrument used in laparoscopic or transvaginal gynecological procedures. It is primarily used to lift and fix the uterus, adjusting its position and angle to provide a clear pelvic view and assist the surgeon in completing the procedure. The device typically includes a handle, a central guide rod, and a uterine cup. The central guide rod is inserted into the uterus, and the uterine cup is used to secure the external os of the cervix. The surgeon uses the handle to control the rotation and swing of the central guide rod, thereby adjusting the angle of the uterus and pulling it to the optimal position for pelvic visualization, exposing the surgical target.
[0003] In existing technologies, the central guide rod is generally made of medical-grade stainless steel, titanium alloy, medical-grade polycarbonate, etc. It is rigid as a whole or fixed with a soft outer layer, and the head cannot be adjusted. When entering the uterine cavity, it is easy to get stuck due to the passage being curved, with adhesions, septa, fibroids, polyps, etc. If the doctor uses too much force, it may cause tissue tearing or even perforation, which can easily damage the nearby intestines, bladder or major blood vessels, causing serious bleeding and infection, increasing the difficulty of the operation, and also causing serious damage to the patient's body. Summary of the Invention
[0004] (a) Technical problems to be solved: To address the shortcomings of existing technologies, this invention provides a uterine lifting device for gynecological surgery, which solves the problem mentioned in the background art that the central guide rod of existing uterine lifting devices for gynecological surgery is rigid or the head is not adjustable, making it easy to get stuck in the uterine cavity.
[0005] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a uterine lifting device for gynecological surgery, comprising: The long rod is hollow and has an eccentric rod at the top that is not coaxial with itself. The inner rod is hollow and includes a plug that is sleeved on the outside of the end of the long rod that enters the uterus. The top of the plug is set as a soft arc-shaped head and a tilt sensor is fixedly connected inside it. The inner insertion rod is used to insert into the long rod and slide inside the long rod, causing the arc-shaped head to enter the uterus before the long rod, avoiding damage to the uterine cavity. After determining the bending angle of the plug when it is stuck by the tilt sensor, the long rod is rotated to adjust the angle of the eccentric rod. The long rod moves towards the plug so that the eccentric rod presses against one side of the arc-shaped head, causing the plug to bend in an axially symmetrical direction with the inner insertion rod as the axis. The bending angle of the plug is actively adjusted to adapt to the internal conditions of the uterine cavity and facilitate insertion into the deep part of the uterine cavity.
[0006] Preferably, the end of the arc-shaped head closest to the uterus is configured as a dome.
[0007] Preferably, it further includes: The outer tube is hollow inside; The first fixing nut is threaded into the outer pipe. The threaded ring has threads on its inner side; The cup is attached to one end of the outer tube where the threaded ring is located, and is used to be threadedly connected to the threaded ring and fixed to the end of the outer tube after being attached to the outer tube; The display unit is located on one side wall of the outer tube.
[0008] Preferably, it further includes: The circuit has one end fixedly connected to the tilt sensor, and the other end passes through the hollow part of the inner rod to the outside of the inner rod and is connected to the display unit to provide the display unit with display parameters.
[0009] Preferably, it further includes: The rotating inner sleeve is hollow rod-shaped and is used to be inserted into the hollow part of the outer sleeve. A rotating head, with a tapered cross-section, is located at one end of the rotating inner sleeve near the plug, and is used to be inserted into the uterus by rotating itself. The second fixing nut is threadedly connected to the rotating inner sleeve.
[0010] Preferably, it further includes: The intermediate sleeve rod is hollow and is used to be inserted into the inside of the rotating inner sleeve. The long rod is inserted inside the sleeve itself. The third fixing nut is threadedly connected to the intermediate sleeve rod; The connector is hollow inside and is located at the bottom of one end of the plug, which is the same diameter as the intermediate sleeve rod. Its inner diameter is smaller than the inner diameter of the intermediate sleeve rod but larger than the diameter of the inner insertion rod. The fourth fixing nut is threadedly connected to the connecting seat; A rotating cavity is formed at the end of the intermediate sleeve rod near the plug, which is used to increase the inner diameter of the end of the intermediate sleeve rod near the plug, providing space for the eccentric rod to rotate and push.
[0011] Preferably, the inner insert rod is inserted into the connector during operation.
[0012] Preferably, it further includes: Several protruding rings are provided on the inner wall of the long rod to reduce the friction between the long rod and the inner insert rod when the long rod rotates; A limiting seat, with a diameter larger than that of the long rod, is disposed at one end of the long rod near the plug, and the protruding ring is fixedly connected to the eccentric rod on the side near the plug, for increasing the distance between the eccentric rod and the central axis of the long rod, and limiting the eccentric rod to be located in the rotating cavity; The rotating adjustment end is located at the end of the long rod away from the plug.
[0013] Preferably, it further includes: A sealing ring is fixedly connected to the end of the plug furthest away from it, and is used to seal the gap between the plug and the long rod.

[0015] (III) Beneficial Effects: The uterine lifting device for gynecological surgery provided by this invention has the following beneficial effects: 1. This gynecological surgical device for lifting the uterus, by setting a soft arc-shaped head that can move independently of the long rod, allows the plug to enter the uterine cavity before the long rod and adapt to the complex internal path, thereby avoiding jamming and tissue damage caused by synchronous movement with the long rod. It also makes it easy to adjust the bending state of the plug when it gets stuck.
[0016] 2. This gynecological surgical device for lifting the uterus utilizes an eccentric rod to push the plug, allowing the plug to bend to a set angle under the doctor's control. This adapts to the complex passages, polyps, and fibroids within the uterine cavity, enabling continuous and deeper insertion and improving the safety and efficiency of the procedure.
[0017] 3. This gynecological surgical device for lifting the uterus, by setting an angle sensor inside the arc-shaped head and connecting it to the display unit through a circuit, allows the doctor to clearly know the bending angle of the arc-shaped head when it moves and gets stuck in the uterine cavity by directly observing the parameters displayed on the display unit, thus providing clear guidance when adjusting the bending angle of the arc-shaped head.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1 refer to Figures 1 to 4 , Figures 13 to 18 A preferred embodiment of the present invention for gynecological surgery using a uterine lifting device will be described in detail below: The long rod 40 is hollow and has an eccentric rod 43 at the top that is not coaxial with itself. This ensures that when the long rod 40 and the eccentric rod 43 are pushed forward, they exert a unilateral pushing force on the arc-shaped head 511, which precisely controls the bending direction of the plug 51 and avoids damage to the uterine cavity caused by uncontrolled bending angle. It also improves the bending sensitivity of the plug 51 and can play a protective role through its own passive bending under normal working conditions.
[0022] The inner insertion rod 50 is a hollow rod shape, including a plug 51 that is sleeved on the outside of the end of the long rod 40 that enters the uterus. The top of the plug 51 is set as a soft arc-shaped head 511. The soft arc-shaped head 511 can reduce friction and collision damage when in contact with the inner wall of the uterine cavity, and an inclination sensor 53 is fixedly connected inside itself. The inner insertion rod 50 is used to insert into the long rod 40 and slide inside the long rod 40, causing the arc-shaped head 511 to enter the uterus before the long rod 40, thus avoiding damage to the uterine cavity. The tilt sensor 53 detects the bending angle of the plug 51 in real time. After determining the bending angle when the plug 51 is stuck, the long rod 40 is rotated to adjust the angle of the eccentric rod 43. The long rod 40 moves towards the plug 51, causing the eccentric rod 43 to press against one side of the arc-shaped head 511, causing the plug 51 to bend in an axially symmetrical direction with the inner insertion rod 50 as the axis. The bending angle of the plug 51 is actively adjusted to adapt to the internal conditions of the uterine cavity and facilitate insertion into the deep part of the uterine cavity, thereby solving the problem of existing devices being prone to getting stuck due to the non-adjustable head, thus improving the safety of the operation.
[0023] The arc-shaped head 511 has a dome-shaped end near the uterus, which improves the guiding ability of the plug 51, allowing it to enter the uterine cavity more smoothly and conform to the inside of the uterine cavity, reducing the risk of jamming and scratching. At the same time, it can also disperse the pressure when in contact with the uterine cavity, avoiding tissue damage caused by excessive local pressure.
[0024] Also includes: The line 54 is fixedly connected at one end to the tilt sensor 53, and at the other end passes through the hollow part of the inner insertion rod 50 to the outside of the inner insertion rod 50, thereby protecting the line 54 from external damage and preventing the line 54 from getting tangled and affecting the operation of the device. It is also connected to the display unit 14 to provide the display unit 14 with the displayed parameters, so that the doctor can intuitively grasp the status of the plug 51, thereby adjusting the bending angle of the plug 51 in time, reducing surgical risks, and improving the insertion efficiency of the plug 51.
[0025] Also includes: Several raised rings 41 are evenly distributed on the inner wall of the long rod 40 to ensure uniform force distribution. These rings reduce friction between the long rod 40 and the inner insert rod 50 during rotation, resulting in smoother relative rotation, reduced effort required by the doctor, improved operational accuracy, and reduced wear caused by friction between the long rod 40 and the inner insert rod 50, thus extending the service life of the device and its components. Furthermore, several evenly distributed raised rings 41 can also be provided on the outer wall of the long rod 40 to further reduce friction between the long rod 40 and the intermediate sleeve rod 30.
[0026] The limiting seat 42 has a diameter larger than that of the long rod 40, which facilitates the installation of the long rod 40 inside the intermediate sleeve rod 30. It is located at the end of the long rod 40 near the plug 51, and the protruding ring 41 is fixedly connected to the eccentric rod 43 on the side near the plug 51. This increases the distance between the eccentric rod 43 and the central axis of the long rod 40, thereby increasing the torque when the eccentric rod 43 pushes the arc-shaped head 511. This makes the bending adjustment of the plug 51 easier and more efficient. It also limits the eccentric rod 43 to be located within the rotating cavity 34, ensuring that the rotation and pushing adjustment of the eccentric rod 43 are always within a preset range. This avoids the adjustment of the plug 51 caused by the offset of the eccentric rod 43, ensuring safety and reliability.
[0027] The rotating adjustment end 44 is located at the end of the long rod 40 away from the plug 51, which is convenient for the doctor to hold and apply rotation and propulsion force, thereby controlling the rotation and position of the eccentric rod 43 and realizing the state adjustment of the plug 51.
[0028] Also includes: The sealing ring 52 is fixedly connected to the end of the plug 51 furthest away from the plug 51. It is used to seal the gap between the plug 51 and the long rod 40, preventing bodily fluids and tissue fluids in the uterine cavity from entering the gap between the plug 51 and the long rod 40 after the plug 51 has fully entered the uterine cavity, which could lead to bacterial growth and infection. At the same time, it can also prevent foreign objects from entering the gap and affecting the relative displacement of the long rod 40 and the plug 51, ensuring the operational flexibility and safety of the device.
[0029] The following is the complete working process and working principle of the above embodiments: The inner insertion rod 50 is located inside the long rod 40, and the long rod 40 is fixed by the third fixing nut 31, while the inner insertion rod 50 is fixed by the fourth fixing nut 33. When it is necessary to insert the plug 51 and part of the long rod 40 into the uterine cavity, the entire device is pushed. At this time, the relative positions of the plug 51, the long rod 40, and the protruding ring 41 are as follows: Figure 3 As shown, during the insertion process, the tilt sensor 53 inside the inner insertion rod 50 detects the bending angle of the plug 51 in real time and transmits the parameters to the display unit 14 on the outer tube 10 through the line 54, so that the doctor can observe it intuitively.
[0030] If the plug 51 does not get stuck during insertion, the entire plug 51 and part of the long rod 40 can be inserted to the appropriate length to complete the insertion. If it gets stuck during insertion, the curved head 511 can be moved elsewhere by controlling the bending of the plug 51 to continue insertion. Specifically, when the plug 51 gets stuck, the doctor judges the bending situation according to the parameters on the display unit 14, and then moves the entire device slightly away from the uterus to dislodge the curved head 511 from the stuck state. Then, rotate the third fixing nut 31 to remove it from contact with the long rod 40, allowing the long rod 40 to move independently. Next, hold the rotating adjustment end 44 of the long rod 40 and rotate it to adjust the angle of the non-coaxial eccentric rod 43 at its top. After adjusting the eccentric rod 43 to a suitable angle, push the long rod 40 independently towards the uterus, causing the eccentric rod 43 to contact one side of the arc-shaped head 511, thereby causing the plug 51 to bend in the preset direction. Actively adjust the bending angle to find a channel for further insertion. At this point, fix the inner rod 50 and plug 51 by rotating the fourth fixing nut 33. Rotate the third fixing nut 31 to allow the long rod 40 to be pushed independently, thus continuing to push the long rod 40 back to its original position. Figure 3 The position shown avoids the situation where the length of the long rod 40 entering the uterine cavity is insufficient due to the excessive movement distance of the plug 51 alone, resulting in poor uterine lifting and movement. If jamming occurs repeatedly, the above operation can be repeated to ensure that the plug 51 and part of the long rod 40 are smoothly inserted into the deep uterine cavity, avoiding tissue damage and improving the safety and efficiency of the operation.
[0031] Example 2 refer to Figures 1 to 15 It also includes: The outer tube 10 is hollow inside. It is the outermost structure and can provide space for the internal components to be accommodated and installed. The outer wall can be provided with a non-slip coating that meets medical standards, making it convenient for doctors to hold and operate other structures.
[0032] The first fixing nut 11 is threadedly connected to the outer tube 10 and is used to fix the rotating inner sleeve 20 inside the outer tube 10. When it is necessary to move the rotating inner sleeve 20, the first fixing nut 11 can be twisted so that the first fixing nut 11 is no longer in contact with the rotating inner sleeve 20, thereby adjusting the position of the rotating inner sleeve 20.
[0033] Threaded ring 12, with threads on the inner side; The uterine cup 13 is snapped onto one end of the outer tube 10 where the threaded ring 12 is provided, ensuring efficient installation and positioning. After being snapped onto the outer tube 10, it is threadedly connected to the threaded ring 12 and fixed to the end of the outer tube 10, thereby achieving further locking and fixing of the uterine cup 13.
[0034] The display unit 14 is located on one side wall of the outer tube 10 and is also equipped with a power supply and other components. This allows the doctor to observe the bending parameters of the plug 51 at any time during the insertion process. If the plug 51 gets stuck, the doctor can judge the bending condition of the plug 51 by observing the bending parameters and then actively adjust the bending state of the plug 51 by using the eccentric rod 43 to avoid polyps or fibroids that may cause the plug 51 to get stuck, thus avoiding damage to them and facilitating the subsequent insertion of the plug 51.
[0035] Also includes: The inner sleeve 20 is a hollow rod-shaped rotating sleeve, which provides installation space for the middle sleeve 30 and is used to insert into the hollow part of the outer tube 10. The rotating head 21, with a conical cross-section, is located at one end of the rotating inner cannula 20 near the plug 51 and is used to insert into the uterus by rotating itself. The conical cross-section gives the rotating head 21 strong guiding and puncture capabilities, allowing it to pass through the cervix and enter the uterus through rotational insertion. This reduces patient discomfort during insertion and improves the comfort and safety of the procedure.
[0036] The second fixing nut 22 is threadedly connected to the rotating inner sleeve 20 and is used to fix the intermediate sleeve 30 set inside the rotating inner sleeve 20, so as to ensure the stability of the intermediate sleeve 30 during the operation and avoid displacement from affecting the operation.
[0037] Also includes: The intermediate sleeve rod 30 is hollow rod-shaped and is used to be inserted into the inside of the rotating inner sleeve 20. The long rod 40 is inserted inside itself. The third fixing nut 31 is threadedly connected to the intermediate sleeve rod 30. The contact state between the third fixing nut 31 and the long rod 40 can be adjusted by rotation to fix the third fixing nut 31, or the movement of the long rod 40 within the intermediate sleeve rod 30 can be adjusted.
[0038] The connector 32 is hollow inside and is located at the bottom of one end of the plug 51 of the intermediate sleeve rod 30. It has the same diameter as the intermediate sleeve rod 30, so it can be directly inserted into the rotating inner sleeve 20 along with the intermediate sleeve rod 30. Its inner diameter is smaller than the inner diameter of the intermediate sleeve rod 30 but larger than the diameter of the inner insertion rod 50, so that the inner insertion rod 50 can be inserted into the connector 32, ensuring that the intermediate sleeve rod 30, the long rod 40 and the inner insertion rod 50 are stably coaxial.
[0039] The fourth fixing nut 33 is threadedly connected to the connecting seat 32. When the inner insertion rod 50 is inserted into the connecting seat 32, rotating the fourth fixing nut 33 can lock the inner insertion rod 50, preventing the inner insertion rod 50 from sliding or rotating during the operation and ensuring the stability of the operation. Alternatively, rotating the fourth fixing nut 33 can prevent the fourth fixing nut 33 from contacting the inner insertion rod 50, thereby allowing the displacement of the inner insertion rod 50 to be adjusted independently (the long rod 40 is fixed by the third fixing nut 31), so that the plug 51 can move independently outside the long rod 40.
[0040] The rotating cavity 34 is located at the end of the intermediate sleeve rod 30 near the plug 51. It is used to increase the inner diameter of the end of the intermediate sleeve rod 30 near the plug 51, increase the pushing and bending effect of the eccentric rod 43 on the plug 51, and provide space for the eccentric rod 43 to rotate and push.
[0041] During operation, the inner insert rod 50 is inserted into the connecting seat 32 to prevent the inner insert rod 50 and the long rod 40 from being fixed simultaneously. This would prevent the inner insert rod 50 from moving regardless of whether it is fixed to the long rod 40 or the inner insert rod 50. It also prevents the difficulty of operation caused by installing a fixing nut on the long rod 40, given the small distance between the long rod 40 and the inner insert rod 50.
[0042] The first fixing nut 11, the second fixing nut 22, the third fixing nut 31 and the fourth fixing nut 33 are arranged in the same plane, which makes it convenient for doctors to operate each nut in one place during the operation without having to frequently adjust the position of their hands or rotate the device, thus improving the convenience and efficiency of the operation. At the same time, it can avoid mutual interference between the nuts, ensure a smooth operation, and reduce the risk of errors caused by limited operating space.
[0043] The following is the complete working process and working principle of the above embodiments: The outermost tube 10 provides installation space as the outermost structure. After the doctor holds the outermost tube 10, the uterine cup 13 is attached to the outermost tube 10 and fixed with the threaded ring 12. Then, the rotating inner sleeve 20 is inserted into the outermost tube 10 and adjusted to a suitable position. Then, the second fixing nut 22 is turned to fix the middle sleeve 30 inside the rotating inner sleeve 20. Next, the long rod 40 is inserted into the middle sleeve 30 and the inner insertion rod 50 is inserted into the long rod 40 and the connecting seat 32 in the same way. The long rod 40 is fixed with the third fixing nut 31 and the inner insertion rod 50 is fixed with the fourth fixing nut 33. At this time, the entire device can be used. In use, the plug 51 end of the entire device is inserted into the vagina. The tapered end of the rotating inner sleeve 20 is rotated and inserted into the uterus. Through the cooperation of the long rod 40, the eccentric rod 43, the inner insertion rod 50, the plug 51, etc., it is inserted into the uterine cavity to a suitable depth. At this time, the uterine cup 13 fits onto the external os of the cervix, which facilitates the adjustment of the angle and position of the uterus. This device achieves safe and efficient insertion into the uterine cavity and adjustment of the uterus through the cooperation of its various components, providing a clear field of vision for the surgery.
