Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a sterile uterine manipulator capable of achieving multi-angle support. Background Art

[0002] A uterine manipulator is a surgical instrument commonly used to manipulate the uterus during gynecological surgery. Typically made of stainless steel and featuring a unique design and shape, it consists of a central guide rod, cervical fixator, and dome cup. It can be used for laparoscopically assisted vaginal hysterectomy, laparoscopic hysterectomy, laparoscopic fallopian tube dye perfusion, and various laparoscopic procedures. Before the advent of the uterine manipulator, guide rods were generally used to manipulate the uterus and raise it to the desired position. However, due to the small diameter of the guide rod, the uterus was prone to shaking during surgery, resulting in suboptimal positioning and control. This could prolong the procedure, not only failing to achieve the desired outcome, but could even lead to surgical accidents.

[0003] Traditional uterine manipulators have certain drawbacks. They consist of three main components: a central guide rod, a cervical fixator, and a uterine cup. The central guide rod is non-adjustable, meaning the surgeon cannot adjust the angle and position of the uterine manipulator during surgery. This affects the surgical field of view and operating space, potentially impacting the efficiency and safety of the procedure. Therefore, a sterile uterine manipulator with multi-angle support was proposed. Summary of the invention

[0004] In view of the problem that the central guide rod design of traditional uterine manipulators in the prior art cannot be adjusted, which means that during the operation, the doctor cannot adjust the angle and position of the uterine manipulator as needed, which will affect the surgical field of view and operating space, and thus may affect the efficiency and safety of the operation. The purpose of the present invention is to provide a sterile uterine manipulator that can achieve multi-angle support.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A sterile uterine manipulator capable of achieving multi-angle support comprises a rod body, on which a uterine cavity support member, a uterine lifting cup, and a vaginal seal are sequentially arranged from top to bottom. The rod body comprises a movable rod and a fixed rod, between which a bending mechanism is provided. The bending mechanism is located between the uterine lifting cup and the vaginal seal, and the bending mechanism enables the movable rod to rotate about the end of the fixed rod.

[0007] The bending mechanism includes a connecting sleeve, a rotating plate, an annular groove, and a connecting rod. The connecting sleeve is flexible, and both ends of the connecting sleeve are fixedly sleeved on the outer surfaces of the movable rod and the fixed rod end respectively. The annular groove is circumferentially opened on the inner surface of the movable rod. A rotating plate adapted thereto is installed inside the annular groove, and the rotating plate is arranged along the diameter of the annular groove. The connecting rod is arranged at the center of the movable rod, and a sliding groove is opened inside the movable rod. The rotating plate is installed in the middle of the sliding groove through a connecting shaft. A pull rod is arranged at a position of the rotating plate deviating from the connecting shaft. A groove body is opened on the surface of the rotating plate. The top of the pull rod is horizontally inserted into the groove body, and the top of the pull rod can move inside the groove body, and the top of the pull rod can be rotationally matched with the rotating plate. One ends of the pull rod and the connecting rod both extend to one end of the fixed rod and are provided with a control mechanism. The control mechanism is located at one end of the fixed rod surface away from the movable rod. The control mechanism controls the rotation direction and angle of the movable rod by controlling the movement of the rotating plate.

[0008] Optionally, the control mechanism includes a rotating seat, a rotating groove, and a handle. A rotating groove adapted to the fixed rod is opened on the surface of the rotating seat. The end of the fixed rod away from the movable rod is fitted and installed inside the rotating groove. One end of the pull rod penetrates through the rotating seat and is fixedly connected with the handle. A linear array of limiting holes is opened on the surface of the pull rod along its moving direction. A surrounding insertion hole is opened on the surface of the fixed rod at the part located in the rotating groove. A limiting rod is axially inserted into the surface of the rotating seat. The limiting rod can be moved into or out of the limiting hole and the insertion hole.

[0009] Optionally, a return spring is sleeved on the surface of the part of the pull rod located outside the rotating seat. One end of the return spring is fixedly connected with the rotating seat, and the other end of the return spring is fixedly connected with the handle. In the natural state of the return spring, the rotating plate and the connecting rod are kept perpendicular.

[0010] Optionally, the vaginal seal includes a cavity, an air hole, a sealing capsule body, and an air delivery pipeline. The cavity is opened on the inner wall of the fixed rod. The sealing capsule body is sleeved on the outer surface of the fixed rod, and the cavity is located inside the sealing capsule body. An air hole is opened on the surface of the cavity. The air hole communicates the sealing capsule body with the cavity. One end of the air delivery pipeline is communicated with the cavity, and the other end of the air delivery pipeline is located outside the lower part of the fixed rod.

[0011] Optionally, the uterine cavity support includes a cystic support. The cystic support includes a support capsule body, through holes, an air inlet pipeline, and a hollow tube. The hollow tube is fixedly installed at the upper end of the movable rod. The through holes are uniformly distributed on the surface of the hollow tube. The support capsule body is sleeved on the outer surface of the hollow tube. The through holes communicate the support capsule body with the hollow tube. One end of the air inlet pipeline is connected in a through manner with the end of the hollow tube, and the other end of the air inlet pipeline is located outside the lower part of the fixed rod.

[0012] Optionally, the uterine cavity support member includes a rod-shaped support member, which includes an electric push rod, an electromagnet, a pressing plate, a sleeve, and a telescopic rod. The electric push rod is fixedly installed inside the fixed rod, and the telescopic end of the electric push rod is fixedly connected to the electromagnet. The electric push rod can move the electromagnet to the upper end of the fixed rod. The pressing plate is fixedly installed at one end of the electromagnet outside the fixed rod. There are two groups of sleeves, both groups of sleeves are magnetic, and both groups of sleeves are rotatably installed at the upper end of the movable rod through a rotating shaft. The on-off of the electromagnet power supply controls the deflection of the sleeve. When the electromagnet is powered off, the sleeve deflects to both sides, and the pressing plate can form a moving interference in the rotating direction of the sleeve.

[0013] Optionally, telescopic rods are arranged inside the sleeves respectively. The telescopic rods can move at one end of the sleeves away from the rotating shaft. One end of the telescopic rod located inside the sleeve is fixedly connected with a piston, and the piston is in sliding and sealing fit with the sleeve. A telescopic spring is sleeved on the outer surface of the part of the telescopic rod located inside the sleeve.

[0048] Example 1: As Figures 1 to 6 shown, an embodiment of the present invention provides a sterile uterine manipulator capable of multi-angle support, including a rod body 1. The rod body 1 is sequentially provided with a uterine cavity support member, a uterine cup 3, and a vaginal seal 4 from top to bottom. The rod body 1 includes a movable rod 11 and a fixed rod 12. A bending mechanism 7 is provided between the movable rod 11 and the fixed rod 12. The bending mechanism 7 is located between the uterine cup 3 and the vaginal seal 4. The bending mechanism 7 can make the movable rod 11 rotate around the end of the fixed rod 12;

[0049] The bending mechanism 7 includes a connecting sleeve 71, a rotating plate 72, an annular groove 73, and a connecting rod 74. The connecting sleeve 71 is flexible, and both ends of the connecting sleeve 71 are fixedly sleeved on the outer surfaces of the end parts of the movable rod 11 and the fixed rod 12 respectively. The annular groove 73 is circumferentially formed on the inner surface of the movable rod 11. A rotating plate 72 adapted thereto is installed inside the annular groove 73, and the rotating plate 72 is arranged along the diameter of the annular groove 73. The connecting rod 74 is arranged at the central part inside the movable rod 11, and a sliding groove 75 is formed inside the movable rod 11. The rotating plate 72 is installed in the middle of the sliding groove 75 through a connecting shaft 76. A pull rod 77 is arranged at a position of the rotating plate 72 deviating from the connecting shaft 76. A groove body is formed on the surface of the rotating plate 72. The top of the pull rod 77 is horizontally inserted into the groove body, and the top of the pull rod 77 can move inside the groove body, and the top of the pull rod 77 can be rotationally matched with the rotating plate 72. One ends of the pull rod 77 and the connecting rod 74 both extend to one end of the fixed rod 12 and are provided with a control mechanism 8. The control mechanism 8 is located at one end of the fixed rod 12 away from the movable rod 11. The control mechanism 8 controls the rotation direction and angle of the movable rod 11 by controlling the movement of the rotating plate 72.

[0050] The control mechanism 8 includes a rotating seat 81, a rotating groove 82, and a handle 83. A rotating groove 82 adapted to the fixed rod 12 is formed on the surface of the rotating seat 81. One end of the fixed rod 12 away from the movable rod 11 is fitted and installed inside the rotating groove 82. One end of the pull rod 77 penetrates through the rotating seat 81 and is fixedly connected with the handle 83. A linear array of limiting holes 85 is formed on the surface of the pull rod 77 along its moving direction. An annularly arranged insertion hole 87 is formed on the surface of the part of the fixed rod 12 located in the rotating groove 82. A limiting rod 86 is axially inserted into the surface of the rotating seat 81, and the limiting rod 86 can be moved into or out of the limiting holes 85 and the insertion hole 87.

[0051] A return spring 84 is sleeved on the surface of the part of the pull rod 77 located outside the rotating seat 81. One end of the return spring 84 is fixedly connected with the rotating seat 81, and the other end of the return spring 84 is fixedly connected with the handle 83. In the natural state of the return spring 84, the rotating plate 72 and the connecting rod 74 are kept perpendicular.

[0052] Both sides of the outer surface of the lower part of the fixed rod 12 are fixedly connected with handles 5, and the handles 5 are both arranged radially along the fixed rod 12.

[0053] Specifically, the user holds the handle 5 with one hand and holds the rotating seat 81 with the other hand. By rotating the rotating seat 81, the connecting rod 74, the rotating plate 72, and the pull rod 77 are driven to rotate axially around the fixed rod 12, thereby adjusting the position of the rotating plate 72 and controlling the rotation direction of the rotating plate 72. In addition, the user can simultaneously use a finger to pull the handle 83 to drive the pull rod 77 to move, causing the rotating plate 72 to tilt, thereby driving the movable rod 11 to bend. Among them, the bending angle of the movable rod 11 is controlled by the moving distance of the pull rod 77. Finally, by setting the limiting rod 86 to insert into the limiting hole 85 and the insertion hole 87, the pull rod 77, the rotating seat 81, and the connecting rod 74 are fixed, so that the movable rod 11 and the fixed rod 12 are kept vertical or bent.

[0054] It should be noted that: the inner diameter of the movable rod 11 is much larger than the outer diameter of the connecting rod 74. The gap between the connecting rod 74 and the connecting rod 74 can provide a certain amount of movement space for the movable rod 11. In addition, the material of the connecting sleeve 71 can be rubber, which can deform to ensure that the movable rod 11 can bend relative to the fixed rod 12.

[0055] In this embodiment, by setting the control mechanism 8 to cooperate with the bending mechanism 7, the movable rod 11 can be bent in all directions, so as to adjust the angle and direction of the movable rod 11 according to actual operation needs, facilitate expanding the surgical field of view, expanding the surgical operation space, reducing the surgical operation difficulty, and meeting various surgical requirements.

[0056] It should be noted that: when the pull rod 77 drives the rotating plate 72 to tilt and the movable rod 11 and the fixed rod 12 are bent, the return spring 84 undergoes elastic deformation; when it is necessary to change the bent movable rod 11 and the fixed rod 12 into the vertical movable rod 11 and the fixed rod 12, only need to move the limiting rod 86 out of the limiting hole 85 and the insertion hole 87, and the return spring 84 can drive the pull rod 77 to reset, so that the rotating plate 72 rotates back to be perpendicular to the connecting rod 74, thereby changing the bent movable rod 11 and the fixed rod 12 into the vertical movable rod 11 and the fixed rod 12.

[0057] The vaginal seal 4 includes a cavity 41, an air hole 42, a sealing capsule 43, and an air delivery pipe 44. The cavity 41 is opened on the inner wall of the fixed rod 12. The sealing capsule 43 is sleeved on the outer surface of the fixed rod 12, and the cavity 41 is located inside the sealing capsule 43. The air hole 42 is opened on the surface of the cavity 41, and the air hole 42 communicates the sealing capsule 43 with the cavity 41. One end of the air delivery pipe 44 is communicated with the cavity 41, and the other end of the air delivery pipe 44 is located outside the lower part of the fixed rod 12.

[0058] After the vaginal seal 4 is sent into the vagina by using the rod body 1, gas is transported through the gas pipeline 44. The gas enters the inside of the sealing capsule 43 through the gas pipeline 44, the cavity 41 and the air holes 42, causing the sealing capsule 43 to expand and fit against the inner wall of the vagina, thereby sealing the vagina and avoiding gas leakage when cutting the vaginal wall.

[0059] The uterine cavity support member includes a cystic support member 2. The cystic support member 2 includes a support capsule 21, through holes 22, an air inlet pipeline 23 and a hollow tube 24. The hollow tube 24 is fixedly installed at the upper end of the movable rod 11. The through holes 22 are evenly distributed on the surface of the hollow tube 24. The support capsule 21 is sleeved on the outer surface of the hollow tube 24. The through holes 22 communicate the support capsule 21 with the hollow tube 24. One end of the air inlet pipeline 23 is connected to the end of the hollow tube 24 in a penetrating manner, and the other end of the air inlet pipeline 23 is located outside the lower part of the fixed rod 12.

[0060] In this embodiment, after the uterine cavity support member is sent into the uterus by using the rod body 1, gas is transported through the air inlet pipeline 23. The gas enters the inside of the support capsule 21 through the air inlet pipeline 23, the hollow tube 24 and the through holes 22, causing the support capsule 21 to expand, thereby supporting the uterus.

[0061] Embodiment 2: On the basis of Embodiment 1, as Figures 7 to 10 shown, a uterine cavity support member with better supporting force is proposed. The uterine cavity support member includes a rod-shaped support member 6. The rod-shaped support member 6 includes an electric push rod 61, an electromagnet 62, a pressing plate 63, a sleeve 64 and a telescopic rod 65. The electric push rod 61 is fixedly installed inside the fixed rod 12. The telescopic end of the electric push rod 61 is fixedly connected to the electromagnet 62. The electric push rod 61 can move the electromagnet 62 to the upper end of the fixed rod 12. The pressing plate 63 is fixedly installed at one end of the electromagnet 62 outside the fixed rod 12. There are two groups of sleeves 64. Both groups of sleeves 64 are magnetic, and both groups of sleeves 64 are rotatably installed at the upper end of the movable rod 11 through a rotating shaft 68. The on-off of the power supply of the electromagnet 62 controls the deflection of the sleeve 64. When the electromagnet 62 is powered off, the sleeve 64 deflects to both sides, and the pressing plate 63 can form a moving interference on the sleeve 64 in the rotation direction.

[0062] Each of the sleeves 64 is internally provided with a telescopic rod 65. The telescopic rod 65 can move at one end of the sleeve 64 away from the rotating shaft 68. One end of the telescopic rod 65 located inside the sleeve 64 is fixedly connected with a piston. The piston is in sliding and sealing cooperation with the sleeve 64. A telescopic spring 66 is sleeved on the outer surface of the part of the telescopic rod 65 located inside the sleeve 64. One end of the telescopic spring 66 is fixedly connected to the inner surface of the sleeve 64, and the other end of the telescopic spring 66 is fixedly connected to the piston part of the telescopic rod 65. The other ends of the connecting pipes 67 are all connected to the outside of the lower part of the fixed rod 12.

[0063] In this embodiment, the rod-shaped support member 6 has a higher supporting strength compared to the cystic support member 2. The rod-shaped support member 6 has two working states: retracted and expanded. The rod-shaped support member 6 in the retracted state is easy to enter the uterine cavity. The expanded rod-shaped support member 6 is arranged in a T-shaped structure similar to the uterine structure and can provide good support for the uterus. Specifically, the electric push rod 61 is used to extend the movable rod 11 of the electromagnet 62, and the power supply of the electromagnet 62 is turned on to make the electromagnet 62 generate magnetism. The electromagnet 62 can thus adsorb the sleeve 64, making the sleeve 64 fit on the surface of the electromagnet 62. This is the retracted state of the rod-shaped support member 6. When it is necessary to switch the rod-shaped support member 6 to the expanded state, only the power supply of the electromagnet 62 needs to be cut off to make the electromagnet 62 lose magnetism, and then the electric push rod 61 is driven to contract, making the electromagnet 62 partially retract into the movable rod 11. During this process, the pressing plate 63 also moves accordingly. Both sides of the pressing plate 63 and both ends of the sleeve 64 are provided with inclined surfaces. When the pressing plate 64 moves, it will push the sleeve 64 to deflect to both sides. And when the pressing plate 64 moves to the bottom of the sleeve 64, the pressing plate 63 will press on the surfaces of the two sleeves 64, forming a movement interference on the sleeve 64 to prevent the sleeve 64 from deflecting. At this time, the two sleeves 64 and the movable rod 11 form a T-shaped structure to support the uterus. When it is necessary to restore the rod-shaped support member 6 to the retracted state, the electric push rod 61 is extended to drive the electromagnet 62 to extend out of the movable rod 11, and the pressing plate 63 moves back with the movable rod 11 and no longer presses on the sleeve 64. Then the electromagnet 62 is turned on again, and the electromagnet 62 attracts the sleeve 64 by electricity, making the sleeve 64 rotate to the surface of the electromagnet 62, thus completing the retraction of the sleeve 64.

[0064] In addition, gas is conveyed into the sleeve 64 through the connecting pipe 67. The gas can thus push the telescopic rod 65 out of the sleeve 64, thereby adjusting the overall length of the horizontal part of the rod-shaped support member 6 in the expanded state, that is, the overall length of the sleeve 64 and the telescopic rod 65, so as to support uteri of different sizes. Among them, the overall length of the sleeve 64 and the telescopic rod 65 is controlled by the volume of the input gas. During the movement of the telescopic rod 65, the telescopic spring 66 is compressed. After the operation, the gas can be pumped out through the connecting pipe 67. At this time, the compressed telescopic spring 66 resets, driving the telescopic rod 65 to reset.

[0065] It should be noted that a battery assembly can be arranged inside the movable rod 11 or the fixed rod 12 to provide power for the electric push rod 61 and the electromagnet 62. Corresponding buttons can be arranged on the outer surface of the lower part of the fixed rod 12. Pressing the buttons can control the switches of the electric push rod 61 or the electromagnet 62. Among them, the involved circuits and related driving programs are all existing conventional technologies and will not be elaborated here.

[0066] One end of the air inlet pipe 23, the gas transmission pipe 44, and the connecting pipe 67 located outside the fixed rod 12 are all provided with connectors, and the connectors can be connected to an external gas transmission component.

[0067] Installation grooves adapted to the intake pipeline 23, the air delivery pipeline 44, and the connecting pipe 67 are pre-opened on the inner walls of the movable rod 11 and the fixed rod 12, and the intake pipeline 23, the air delivery pipeline 44, and the connecting pipe 67 are respectively installed inside the corresponding installation grooves.

[0068] In this embodiment, the external air delivery assembly can be an existing micro air pump or other manual or automatic air delivery devices, as long as it can achieve the air delivery or air extraction function. Among them, the connector needs to be selected from existing sealed detachable connectors, such as sealed threaded connectors, etc., which will not be elaborated here.

[0069] The specific working process of the technical solution provided by the present invention is as follows:

[0070] During actual use, the rod body 1 is inserted into the uterine cavity, so that the cup mouth of the uterine lifting cup 3 is closely attached to the vaginal fornix. The uterine cavity support member is used to fixedly support the uterus, and the vaginal seal 4 is used to block the vagina. When the vaginal wall is incised during the operation, the vaginal seal 4 can effectively prevent carbon dioxide gas from leaking.

[0071] In addition, the rotation direction and angle of the bending mechanism 7 can be controlled by the control mechanism 8, and the angle of the uterus can be adjusted according to the surgical needs to fully expose the surgical field.

[0072] The present invention covers any substitutions, modifications, equivalent methods, and solutions made within the essence and scope of the present invention. In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0073] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
