Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a uterine lifting device. Background Technology

[0002] Uterine manipulators are a relatively new type of laparoscopic instrument used in recent years, primarily for fixing and lifting the uterus during total or subtotal hysterectomy. Depending on their design, uterine manipulators are mainly classified into three types: multi-headed manipulators, plug-type manipulators, and cup-type manipulators, with the cup-type being the most commonly used. However, existing cup-type manipulators do not provide adequate fixation of the cervical canal, resulting in a poor surgeon's experience and limited practicality. Furthermore, the fixation mechanism of cup-type manipulators cannot provide sufficient outward pulling force, leading to poor surgical outcomes in cases of large uteri. While full insertion of the manipulator into the uterine cavity is suitable for removing small uteri, it restricts the operating space and severely impacts surgical exposure in cases of large uteri, especially giant uteri. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a uterine lifting device that can overcome the above-mentioned defects, can effectively fix the cervical canal, reduce the difficulty of operation, and is highly practical.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows: A uterine lifting device includes a uterine lifting mechanism, a clamping mechanism, and a telescopic mechanism. The clamping mechanism is inserted through the uterine lifting mechanism, and the telescopic mechanism is connected to the clamping mechanism. In use, the uterine lifting mechanism is placed at the patient's cervical canal, and the telescopic mechanism drives the clamping mechanism to fix the cervical canal.

[0005] In the above scheme, the clamping mechanism includes a probe assembly and a dental plate. The probe assembly is inserted into the uterine lifting mechanism, and the dental plate is disposed inside the probe assembly and extends outside the probe assembly.

[0006] In the above scheme, the probe assembly includes a needle tip and a needle body, and a receiving cavity for accommodating the dental piece is formed between the needle tip and the needle body. One end of the dental piece is disposed in the receiving cavity, and the other end extends to the outside of the receiving cavity and is connected to the telescopic mechanism.

[0007] In the above scheme, the needle tip, the needle body, and the accommodating cavity are integrally formed.

[0008] In the above scheme, a cover is provided on the accommodating cavity, and the cover is connected to the accommodating cavity.

[0009] In the above scheme, the telescopic mechanism includes a telescopic rod, a rotating nut, and a transmission rod. The telescopic rod is inserted into the needle body and the receiving cavity. The rotating nut is located on the telescopic rod at one end away from the receiving cavity. One end of the transmission rod is connected to the telescopic rod, and the other end is connected to the dental plate. In use, the rotating nut drives the telescopic rod to extend and retract, so that the dental plate clamps the cervical canal under the action of the transmission rod.

[0010] In the above scheme, the telescopic rod is provided with a slot for accommodating the transmission rod.

[0011] In the above scheme, the uterine lifting mechanism includes a cup body, a cup handle, and a limiting member. The cup body is sleeved on the receiving cavity, the cup handle is sleeved on the needle body, and the cup body is connected to the cup handle through the limiting member.

[0012] In the above solution, the cup body and the cup handle are provided with threads that cooperate with the limiting member.

[0013] In the above scheme, the cup handle is provided with a handle.

[0014] In the above scheme, the uterine lifting device also includes a fixing nut for fixing the needle body, and the fixing nut is connected to the needle body through the cup handle.

[0015] Compared with the prior art, the present invention sets the clamping mechanism inside the uterine lifting mechanism and connects the telescopic mechanism with the clamping mechanism, so that the telescopic mechanism can drive the clamping mechanism to clamp the cervical canal; the present invention can be matched with cervical canals of different diameters, and can fix the cervical device during surgery to prevent slippage, and can meet the requirements of providing force to pull the uterus outward, which is more suitable for the needs of surgical operation exposure; the present invention has a simple structure, strong practicality, and a good experience for surgeons.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0020] An embodiment of the present invention provides a uterine lifting device, see [link to embodiment]. Figures 1 to 6 It includes a uterine lifting mechanism 1, a clamping mechanism 2, and a telescopic mechanism 3. The clamping mechanism 2 is inserted through the uterine lifting mechanism 1, and the telescopic mechanism 3 is connected to the clamping mechanism 2. In use, the uterine lifting mechanism 1 is placed at the patient's cervical canal, and the telescopic mechanism 3 drives the clamping mechanism 2 to fix the cervical canal.

[0021] By adopting the above solution, the present invention sets the clamping mechanism 2 inside the uterine lifting mechanism 1 and connects the telescopic mechanism 3 with the clamping mechanism 2, so that the telescopic mechanism 3 can drive the clamping mechanism 1 to clamp the cervical canal; the present invention can match cervical canals of different diameters, and can fix the cervical device during surgery so that it is not easy to slip off, and can meet the requirements of providing force to pull the uterus outward, which is more suitable for the needs of surgical operation exposure; the present invention has a simple structure, strong practicality, and a good experience for surgeons.

[0022] See Figures 1 to 3In a specific implementation of this invention, the clamping mechanism 2 further includes a probe assembly 21 and a dental plate 22. The probe assembly 21 is inserted into the uterine lifting mechanism 1, and the dental plate 22 is disposed within the probe assembly 21 and extends beyond it. The probe assembly 21 is used to measure the depth of the patient's uterine cavity and determine the position of the uterus; the dental plate 22 cooperates with the probe assembly 21 to clamp the patient's cervical canal.

[0023] In a specific implementation of this embodiment of the invention, the probe assembly 21 further includes a needle tip 211 and a needle body 212. A receiving cavity 213 for accommodating the dental flap 22 is formed between the needle tip 211 and the needle body 212. One end of the dental flap 22 is disposed within the receiving cavity 213, and the other end extends outside the receiving cavity 213 and is connected to the telescopic mechanism 3. The needle tip 211 and the dental flap 22 cooperate to clamp the cervical canal, thereby fixing the cervical canal. The needle body 212 provides a certain operating depth. The receiving cavity 213 is used to accommodate the dental flap 22.

[0024] Furthermore, in this embodiment of the invention, one end of the dental plate 22 is provided with a rotating shaft, and the dental plate 22 can be rotated through the rotating shaft.

[0025] In a specific implementation of this invention, the needle tip 211, the needle body 212, and the accommodating cavity 213 are integrally formed.

[0026] Furthermore, in this embodiment of the invention, the length of the needle 211 is 40~50mm.

[0027] Furthermore, in this embodiment of the invention, the length of the needle 211 extending to the outside of the uterine lifting mechanism 1 is 30~40mm.

[0028] Furthermore, in this embodiment of the invention, the needle body 212 is provided with scale lines. These scale lines are used to observe the depth of insertion into the patient's body.

[0029] See Figure 3 In a specific implementation of this embodiment of the invention, a cover 214 is further provided on the accommodating cavity 213, and the cover 214 is connected to the accommodating cavity 213. When the cover 214 is opened, the inside of the accommodating cavity 213 can be cleaned; when the cover 214 is closed, it can prevent leakage.

[0030] See Figures 1 to 3In a specific implementation of this invention, the telescopic mechanism 3 further includes a telescopic rod 31, a rotating nut 32, and a transmission rod 33. The telescopic rod 31 is inserted into the needle body 212 and the receiving cavity 213. The rotating nut 32 is located on the telescopic rod 31 at one end away from the receiving cavity 213. One end of the transmission rod 33 is connected to the telescopic rod 31, and the other end is connected to the dental plate 22. In use, the rotating nut 32 drives the telescopic rod 31 to extend and retract, so that the dental plate 22 clamps the cervical canal under the action of the transmission rod 33. The rotating nut 32 is used to extend and retract the telescopic rod 31 relative to the needle body 212, thereby driving the transmission rod 33 to rotate. The transmission rod 33 abuts against the dental plate 22, so that the transmission rod 33 can drive the dental plate 22 to rotate around its fixed axis, thereby achieving the clamping of the cervical canal.

[0031] In a specific implementation of this invention, the accommodating cavity 213 is further provided with holes for the dental plate 22 and the transmission rod 33 to pass through.

[0032] In a specific implementation of this embodiment of the invention, the telescopic rod 31 is further provided with a slot for accommodating the transmission rod 33.

[0033] Furthermore, in this embodiment of the invention, the transmission rod 33 is a smooth cylindrical shape, and the inner wall of the slot is also a smooth curved surface. The two can cooperate to make the transmission rod 33 change position with the telescopic rod 31 during the telescopic process, thereby driving one end of the toothed plate 22 to rotate.

[0034] Furthermore, in this embodiment of the invention, the transmission process of the telescopic rod 31, the rotating nut 32, the transmission rod 33, and the toothed plate 22 is as follows: Rotating the rotating nut 32 causes the telescopic rod 31 to rotate. During the rotation of the telescopic rod 31, it will move relative to the needle body 212 (telescopic). When the telescopic rod 31 rotates to a certain angle, the slot and the transmission rod 33 are locked together, and the telescopic rod 31 can no longer rotate. That is to say, the telescopic rod 31 can no longer move. At this time, the maximum displacement distance of the telescopic rod 31 is reached. The same principle applies when rotating the rotating nut 32 in the opposite direction.

[0035] During the displacement process, the telescopic rod 31 drives the transmission rod 33 to move slightly, which changes the contact position between the transmission rod 33 and the dental plate 22, thereby causing the dental plate 22 to rotate and cooperate with the needle 211 to clamp the cervical canal.

[0036] Furthermore, in this embodiment of the invention, the rotational motion of the rotating nut 32 is partially converted into the rotational motion of the telescopic rod 31, and a portion is converted into the linear motion of the telescopic rod 31. The linear motion of the telescopic rod 31 is then converted into the rotational motion of the toothed plate 22 through the transmission rod 33.

[0037] In a specific implementation of this invention, the telescopic rod 31 and the transmission rod 33 can also be connected by screws or pins (not shown in the figure). This makes it easier to disassemble the telescopic rod 31 and the transmission rod 33.

[0038] In a specific implementation of this invention, the telescopic rod 31 and the transmission rod 33 can also be connected by a hinge or a gear (not shown in the figure). Using a hinge or gear connection makes it easier for the transmission rod 33 to drive the toothed plate 22 to rotate.

[0039] See Figures 1 to 6 In a specific implementation of this invention, the uterine lifting mechanism 1 further includes a cup body 11, a cup handle 12, and a limiting member 13. The cup body 11 is fitted onto the receiving cavity 213, and the cup handle 12 is fitted onto the needle body 212. The cup body 11 is connected to the cup handle 12 via the limiting member 13. The cup body 11 is used to fix the uterus, stabilize the surgical field, protect tissues, and reduce damage. The cup handle 12 is used for precise control, flexible adjustment, stable support, and reduced fatigue. The limiting member 13 is used to fix the cup body 11 and the cup handle 12.

[0040] Furthermore, in this invention, the height of the cup body 11 is 65mm.

[0041] Furthermore, in this invention, the diameter of the cup opening of the cup body 11 is 39~47mm.

[0042] In a specific implementation of this invention, the cup body 11 and the cup handle 12 are further provided with threads that mate with the limiting member 13. This prevents the limiting member 13 from falling off the cup body 11 or the cup handle 12.

[0043] In a specific implementation of this embodiment of the invention, a handle 121 is further provided on the cup handle 12. The handle 121 is used to provide a stable grip and precise control.

[0044] In a specific implementation of this invention, the uterine lifting device further includes a fixing nut 4 for fixing the needle body 212. The fixing nut 4 is connected to the needle body 212 through a cup handle 12. When the fixing nut 4 abuts against the needle body 212, it can fix the position of the needle body 212 and prevent it from shaking or moving.

[0045] Furthermore, in this embodiment of the invention, the cup handle 12 is provided with a hole through which the fixing nut 4 passes.

[0046] In the specific implementation of this invention, the uterine lifting device further limits the length of the rod inserted into the patient's uterus. On the one hand, it is suitable for the positional control of the entire uterine body of a small uterus by traditional uterine lifting devices. On the other hand, it is particularly suitable for large uteruses, reducing the control of the uterine body and strengthening the control of the cervix. In terms of spatial relationship, the cervix can be folded, realizing the control of the uterine body position by intra-abdominal instruments and the control of the cervix position by vaginal instruments, thereby maximizing the efficiency of intra-abdominal space utilization.

[0047] The working process of a uterine lifting device provided in this embodiment of the invention is as follows: See Figures 1 to 6 First, the probe assembly 21 is inserted into the patient's cervix, and the cup body 11 fixes the patient's uterus. Next, the appropriate positions of the needle tip 211 and the needle body 212 are adjusted so that the patient's cervical canal is located between the needle body 212 and the dental plate 22, and the position of the needle tip 211 is fixed by the fixing nut 4. Then, the rotating nut 32 is rotated so that the telescopic rod 31 extends and retracts relative to the needle body 212. Finally, the telescopic rod 31 drives one end of the dental plate 22 to rotate through the transmission rod 33, so that the other end of the dental plate 22 gradually approaches the needle tip 211, completing the fixation process of the patient's cervical canal.

[0048] In summary, this invention, by placing the clamping mechanism 2 within the uterine lifting mechanism 1 and connecting the telescopic mechanism 3 to the clamping mechanism 2, allows the telescopic mechanism 3 to drive the clamping mechanism 1 to clamp the cervical canal. This invention also allows the dental blade 22 to be fixed by cooperating with the needle 211. Simultaneously, this invention uses the rotating nut 32 to drive the telescopic rod 31 to extend and retract, which in turn causes the dental blade 22 to rotate relative to the needle 211 under the action of the transmission rod 33. This invention can accommodate cervical canals of different diameters, and during surgery, it can fix the cervical device to prevent slippage, while also providing the force to pull the uterus outward, better meeting the needs of surgical exposure. This invention has a simple structure, strong practicality, and provides a good experience for the surgeon.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
