Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of medical devices, and particularly relates to a uterine manipulator. BACKGROUND
[0002] The uterine manipulator is mainly used for fixing and lifting the uterus in total or subtotal hysterectomy surgery, and is suitable for moving the uterus or positioning during hysteroscopy or laparoscopy surgery, thereby facilitating the operation of doctors.
[0003] In the field of gynecological surgery, especially in the surgery of uterine mass ablation and hysteroscopic resection, the fixation of the uterus and the protection of the endometrium are key links for the success of the surgery. Under the traditional surgical method, the uterus is prone to displacement due to the lack of stable support, which leads to poor surgical field and increased operation difficulty, and there is a risk of misinjury to the adjacent organs such as the bladder and the intestinal tract. At the same time, the heat generated during the surgery and the operation of the instruments will cause mechanical damage and thermal radiation damage to the endometrium, which easily leads to postoperative complications such as endometrial adhesion, intrauterine infection, and seriously affects the reproductive function and reproductive health of the patient. With the popularization of minimally invasive gynecological surgery, there is an increasingly urgent demand for new medical devices that can accurately fix the uterus and efficiently protect the endometrium.
[0004] The patent with the publication number CN218419924U discloses a novel uterine manipulator with a balloon uterine rod, which comprises two horizontally arranged uterine rods and a sleeve tube connecting the two uterine rods. The ends of the two uterine rods away from the sleeve tube are respectively connected with a uterine rod handle and a balloon. A water pipe is inserted into the uterine rod and the sleeve tube. One end of the water pipe is connected with a one-way valve outside the uterine rod. The other end of the water pipe is in communication with one end of the balloon inside the uterine rod. A sealing head is installed at the end of the balloon away from the uterine rod. A uterine cup is installed on the outside of the uterine rod near the sealing head. During use, the one-way valve is connected to a water inlet pipe or an air inlet pipe. One end of the uterine rod handle is held, and the other end of the uterine rod is held. The handle is rotated to adjust the length of the entire uterine manipulator. Then the entire uterine manipulator is inserted into the vagina. The sealing head and the balloon enter the uterus. Water or gas is injected through the one-way valve to make the balloon inserted into the uterus expand to the size required by the doctor.
[0005] The above technical solution can inject water or gas into the balloon to make it expand to the size required by the doctor. However, the doctor needs to inject water multiple times to accurately control the size of the balloon. If too much water is injected at one time, the balloon will expand too much and damage the uterus, or even cause uterine rupture. The operation is very inconvenient. During the surgical treatment, the surgical instruments will cause mechanical and thermal radiation damage to the endometrium, thereby increasing the risk of postoperative complications such as endometrial adhesion, fluid, and intrauterine infection. It is not conducive to the repair and functional recovery of the postoperative endometrium. The above technical solution cannot solve this problem. SUMMARY

[0018] The present application combines the uterine lifting rod, the first cooling mechanism and the balloon, and the size of the balloon can be adjusted in real time through the first cooling mechanism to avoid damage to the uterus due to excessive expansion of the balloon. The first cooling mechanism can also keep the water in the balloon flowing at all times, i.e., the water in the balloon flows to reduce the temperature inside the uterine cavity, thereby reducing the mechanical and thermal radiation damage to the endometrium caused by surgical instruments, thereby reducing the risk of postoperative complications such as endometrial adhesion, effusion and intrauterine infection, and promoting the repair and functional recovery of the postoperative endometrium.
[0019] The present application combines the uterine lifting rod, the first angle adjusting member and the supporting base, and the medical staff only needs to rotate the knob in the first angle adjusting member to achieve the inclination angle of the uterine lifting rod, so as to adapt to patients of different body shapes to facilitate the uterine lifting rod to enter the patient's uterus and ensure smooth operation.

[0022] This invention, through the combined design of a drive component, a cooling component, and a cooling pipeline, achieves good performance by simultaneously cooling the water flow within the cooling pipeline while the cooling pipeline injects water into the balloon.
[0023] This invention, through the combined design of the first and second cooling mechanisms, can not only cool the flowing water inside the balloon, but also inject flowing water into the uterine cavity to further reduce the uterine cavity temperature. Moreover, it can improve the visibility inside the uterine cavity so that the surgery can be performed smoothly.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0032] The inventor found that the current uterine manipulator needs to be filled with water by the doctor several times in use in order to accurately control the size of the balloon, if more water is filled at one time, the balloon will be inflated larger, which will damage the uterus, and even cause uterine rupture, which is very inconvenient to operate. In addition, in surgical treatment, surgical instruments can cause mechanical and thermal radiation damage to the endometrium, thereby increasing the risk of postoperative endometrial adhesion, fluid, and uterine cavity infection, which is not conducive to the repair and functional recovery of the postoperative endometrium, and the current uterine manipulator cannot solve this technical problem.
[0033] Based on the above findings, this application proposes a uterine lifting device, comprising a support base 1, a lifting rod 2, a first cooling mechanism 3, a balloon 4, a second sleeve 5, a second cooling mechanism 6, a first angle adjusting component 7, and a second angle adjusting component 8. This application achieves more precise adjustment of the balloon's expansion volume and better performance through the following design: 1. The first cooling mechanism 3 can continuously inject water into the balloon 4, and adjust the size of the balloon by controlling the size of the inlet valve 32c and the outlet valve 32d in the first cooling mechanism 3. It can also circulate the water in the balloon 4 throughout the entire use process, so as to carry the heat in the patient's uterine cavity out of the patient's body and reduce the temperature inside the uterine cavity. 2. The lifting rod 2 is connected to the support base 1 through the first angle adjustment component 7, which can adjust the tilt angle of the lifting rod 2 as it enters the patient's uterine cavity, so that the operation can be carried out smoothly; 3. The second cooling mechanism 6 can further reduce the temperature inside the uterine cavity and also improve the visibility inside the uterine cavity; 4. The first angle adjustment component 7 can adjust the overall tilt angle of the lifting rod 2 so that the front end of the lifting rod 2 can smoothly enter the patient's uterine cavity; 5. The second angle adjustment component 8 can adjust the tilt angle of the front end of the uterine lifting rod 2 so that the balloon 4 can fit against the inner wall of the patient's uterus.
[0034] Example 1 This embodiment provides a uterine lifting device, such as Figures 1-19 As shown, it includes a support base 1, a lifting rod 2, a first cooling mechanism 3, a balloon 4, a second sleeve 5, a second cooling mechanism 6, a first angle adjusting component 7, and a second angle adjusting component 8.
[0035] The support base 1 has an inverted T-shaped structure, and the upper end of the support base 1 is provided with a groove for rotating connection with the uterine lift rod 2. In actual use, the support base 1 can be placed on the operating table so that the front end of the uterine lift rod 2 can enter the patient's uterus. Throughout the entire use, medical staff do not need to hold it at all times, reducing the workload of medical staff and saving manpower.
[0036] The lifting rod 2 includes a first rod body 21, a rotator 22, a second rod body 23, a first sleeve 24, and a rotating connector 25; wherein, the first rod body 21 and the second rod body 23 are both tubular structures.
[0037] Specifically, one end of the first rod 21 is rotatably connected to the support base 1 via the first angle adjustment component 7, and the other end is connected to the rotator 22.
[0038] The first angle adjustment assembly 7 includes a connecting post 71, a knob 72, and a fixing hook 73.
[0039] Specifically, the connecting column 71 is fixedly connected with the side of the support base 1.
[0040] The knob 72 is in a cylindrical structure, and a scale line protrusion is fixedly arranged on the side surface thereof; specifically, one end of the knob 72 is fixedly connected with the first rod body 21 through the support base 1; it should be noted that the fixed connection manner of the knob 72 and the first rod body 21 is not limited in the embodiment of the present application, for example, the fixed connection manner is integrally formed connection, welding, buckle connection or welding.
[0041] The fixed hook 73 comprises a fixed hook body 73a, a pressing rod 73b and a second reset spring 73c. The fixed hook body 73a is located at one side of the knob 72, and specifically, the fixed hook body 73a is in a V-shaped structure, and the center corner of the fixed hook body 73a is rotationally connected with the connecting column 71 through a rotating rod; wherein, one end of the fixed hook body 73a close to the knob 72 is provided with a limiting protrusion, and the other end away from the knob 72 is fixedly connected with the pressing rod 73b. One end of the pressing rod 73b away from the fixed hook body 73a is fixedly connected with the second reset spring 73c. One end of the second reset spring 73c away from the pressing rod 73b is embeddedly arranged in the groove on the upper end of the connecting column 71.
[0042] In this way, the medical staff presses one end of the fixed hook body 73a away from the knob 72, at this time, the second reset spring 73c is compressed, and one end of the fixed hook body 73a close to the knob 72 is lifted upward, and then the medical staff can manually rotate the knob 72, the knob 72 drives the first rod body 21 to rotate through the connecting column 71, so as to realize the inclination angle adjustment of the first rod body 21.
[0043] The rotator 22 comprises a rotating ring 22a and a first reset spring 22b.
[0044] Specifically, the rotating ring 22a is arranged at the end of the second rod body 23, and the rotating ring 22a is sleeved with the first reset spring 22b located in the first rod body 21, wherein, one end of the rotating ring 22a close to the first rod body 21 is provided with a gear ring, which is used for meshing connection with the first rod body 21 away from the support base; The first reset spring 22b is arranged in the first rod body 21, and one end of the first reset spring 22b away from the rotating ring 22a is fixedly connected with the first rod body 21; wherein, one end of the first rod body 21 away from the support base is provided with a groove for meshing connection with the gear ring of the rotating ring 22a.
[0045] One end of the second rod body 23 is fixedly connected with the rotating ring 22a, and the other end is rotationally connected with the first sleeve 24 through a rotating connecting piece 25.
[0046] The rotating connector 25 has a U-shaped structure, and a connecting rod 25a is fixedly provided at the center of the rotating connector 25. Both ends of the connecting rod 25a are rotatably connected to the second rod body 23, and the other end is inserted into the first sleeve 24; wherein, the end of the rotating rod 25a is connected to the second angle adjusting member 8.
[0047] The balloon 4 is fitted onto the first sleeve 24. It should be noted that the balloon 4 provided in this embodiment of the invention is prior art, and this embodiment of the invention does not improve upon it.
[0048] The structure of the second angle adjusting member 8 is the same as that of the first angle adjusting member 7; Specifically, the connecting post of the second angle adjusting component 8 is fixedly installed on the outer surface of the second rod 22; One end of the knob of the second angle adjustment component 8 passes through the second rod 22 and is located inside the second rod 22, while the other end is located outside the second rod 22; wherein, the end of the knob located inside the second rod 22 is provided with a first gear, and the first gear is connected to a second gear fixedly set at the end of the rotating rod 25a through a timing belt 81; In this way, similar to the first angle adjustment component 7, medical staff can press the end of the fixed hook body in the second angle adjustment component 8 away from the knob. At this time, the second reset spring is compressed, and the end of the fixed hook body near the knob is lifted up. Then, the medical staff rotates the knob in the second angle adjustment component 8. The knob drives the rotating rod 25a to rotate through the synchronous belt 81. The rotating rod 25a drives the first sleeve 24 to rotate through the rotating connector 25, so that the balloon 4 located on the first sleeve 24 is tilted so that the outer surface of the balloon 4 fits against the inner wall of the patient's uterus. The tilt direction of the balloon 4 can be adjusted by combining it with the rotator 22, so as to adjust the lifting direction of the lifting rod 2 according to the location of the patient's lesion.
[0049] The first cooling mechanism 3 includes a water tank 31, a cooling pipeline 32, a driver 33, a water supply device 34, a first conveyor belt 35, a second conveyor belt 36, a cooling unit 37, a stirring unit 38, and a third conveyor belt 39.
[0050] The water tank 31 is fixedly mounted on the support base 1 and is connected to the cooling pipe 32, the cooling unit 37, and the stirring unit 38. Specifically, the water tank 31 is provided with heat dissipation holes.
[0051] The cooling pipe 32 includes a first water pipe and a second water pipe; the first water pipe and the second water pipe have the same structure, both including a fixed part and a movable part.
[0052] Specifically, the fixed part 32a of the first water pipe is provided with three joints, the first joint is communicated with the fixed part 32a of the second water pipe, the second joint is located outside the second rod body 23 after sequentially passing through the first rod body 21, the rotator 22 and the second rod body 23, so as to be communicated with the movable part located outside the uterus lifting rod 2, and the third joint is communicated with the water injection tank 31; One end of the movable part 32b of the first water pipe is detachably connected with the fixed part by inserting a joint, and the other end is communicated with the inside of the balloon 4 after penetrating into the first sleeve 24; The second water pipe is the same as the first water pipe in structure and connection relationship, and details are not repeated here.
[0053] In this way, the first water pipe, the second water pipe, the balloon 4 and the water injection tank 31 form a closed loop, so that the water in the balloon 4 flows.
[0054] In order to facilitate the adjustment of the water quantity in the balloon 4, the water inlet valve 32c is arranged on the branch of the first water pipe connected with the water injection tank 31, and the water outlet valve 32d is arranged on the branch of the second water pipe connected with the water injection tank 31; The water inlet valve 32c and the water outlet valve 32d are the same in structure, and each includes a ball valve provided with a through hole, and an adjusting handle connected with the ball valve; specifically, the ball valve is located inside the corresponding water pipe, one end of the adjusting handle penetrates into the water pipe and is fixedly connected with the ball valve, and the other end is located outside the corresponding water pipe, so as to be gripped and rotated by medical staff. In the initial state, the central through hole of the ball valve in the water inlet valve 32c is parallel to the inner wall of the first water pipe, and the water in the water injection tank 31 enters other branches of the first water pipe through the central through hole; if the ball valve in the water inlet valve 32c is rotated by the adjusting handle, the central through hole of the ball valve in the water inlet valve 32c is perpendicular to the inner wall of the first water pipe, at this time, the water in the water injection tank 31 cannot pass through the central through hole, that is, the water inlet valve 32c is closed. Similarly, when the central through hole of the ball valve in the water outlet valve 32d is parallel to the inner wall of the second water pipe, the water in other branches of the second water pipe will flow back to the water injection tank 31 through the central through hole; if the ball valve in the water outlet valve 32d is rotated by the adjusting handle, the central through hole of the ball valve in the water outlet valve 32d is perpendicular to the inner wall of the second water pipe, at this time, the water in other branches of the second water pipe cannot pass through the central through hole, that is, the water outlet valve 32d is closed.
[0055] In actual use, the water in the water injection tank 31 enters the balloon 4 through the first water pipe, and then flows back to the water injection tank 31 from the second water pipe, at this time, the water quantity in the balloon 4 can be adjusted by adjusting the valve size of the water inlet valve 32c and the water outlet valve 32d; specifically, the adjustment of the water quantity in the balloon 4 is divided into three cases: Case one, When the water inlet valve 32c is fully opened and the water outlet valve 32d is closed, the water in the water injection tank 31 continuously enters the balloon 4, so that the balloon 4 continuously expands; Case two, When the water inlet valve 32c is fully opened and the water outlet valve 32d is fully opened, the amount of water flowing into the closed loop through the water inlet valve 32c is the same as the amount of water flowing out of the closed loop through the water outlet valve 32d. At this time, the size of the balloon 4 does not change, and the water in the balloon 4 always maintains a flowing state. Case three, When the water inlet valve 32c is closed and the water outlet valve 32d is fully opened, the water in the water injection tank 31 cannot enter the closed loop, and the water in the closed loop continuously flows out of the water outlet valve 32d. At this time, the balloon 4 continuously becomes smaller.
[0056] In order to further ensure the direction of water flow in the closed loop, the driver 33 and the water feeder 34 are arranged in the first rod body 21, and the driver 33 and the water feeder 34 are fixedly connected with the inner wall of the first rod body 21.
[0057] A first rotating wheel and a second rotating wheel are fixedly arranged on the output end of the driver 33, and the first rotating wheel and the second rotating wheel are arranged in parallel with each other. The first rotating wheel is connected with the water feeder 34 through a first conveying belt 35, and the second rotating wheel is connected with the cooling assembly through a second conveying belt 36. Specifically, the first rotating wheel and the second rotating wheel are both cylindrical structures.
[0058] It should be noted that the driver 33 provided in the embodiment of the present application is a prior art, and the embodiment of the present application does not improve it. For example, the driver 33 is a motor, and the model of the motor can be Fuhong F150.
[0059] The water feeder 34 includes a U-shaped plate 34a, a rotating rod 34b, and two extrusion blocks 34c. Each extrusion block 34c is a cylindrical structure.
[0060] Specifically, the U-shaped plate 34a is fixedly connected with the inner wall of the first rod body 21.
