Abstract
Description
Technical Field
[0001] This utility model relates to the field of uterine lifting devices, and particularly to uterine lifting devices. Background Technology
[0002] Uterine manipulators are key instruments used in gynecological laparoscopic surgery to adjust the position of the uterus and expose the surgical field. Current uterine manipulators primarily achieve uterine lifting and angle adjustment through mechanical structures, and their technological development exhibits the following characteristics: Existing uterine manipulators can be divided into three main categories: fixed-angle uterine manipulators, adjustable uterine manipulators, and modular uterine manipulators. Fixed-angle uterine manipulators: These employ an integrated rod-like structure with a fixed angle between the head and handle. Angle adjustment is achieved through an external support or manual force applied by the surgeon, relying on the operator's experience to control stability. Adjustable uterine manipulators: Common improvements include segmented connecting rods with locking nuts, ball joints with knob locking structures, etc., achieving limited angle segmented adjustment through mechanical locking. Modular uterine manipulators: Some products adopt a modular design, adapting to surgical needs by replacing connecting rods with different curvatures, requiring multiple disassembly and assembly of components during surgery.
[0003] The aforementioned uterine lifting device has the following drawbacks in actual use:
[0004] (1) Insufficient flexibility in angle adjustment: Existing mechanical locking structures require repeated tightening / disassembly (such as threaded locking structures), which is time-consuming and prone to loosening. Ball joints have dead zones, making it difficult to achieve continuous and precise adjustment;
[0005] (2) Sealing performance needs to be improved: Gaps are easily generated at the multi-segment connection, resulting in gas leakage during surgery, unstable abdominal pressure, and affecting the stability of the laparoscopic field of view.
[0006] (3) Limited operability: Fixed support type is bulky, while handheld type lacks stable support. Many surgeons have reported that existing products cannot simultaneously meet the needs of open surgery and laparoscopic surgery;
[0007] (4) High assembly complexity: Modular design requires 5-7 assembly steps, increasing the risk of intraoperative contamination and preoperative preparation time;
[0008] (5) Lack of effective surgical guidance and positioning: Existing uterine lifting instruments cannot effectively guide and position the surgical site. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Example 1:
[0037] Please see Figures 1-8As shown, this utility model is a uterine lifting device, including...
[0038] Handle 17;
[0039] The main boom 1 has a toothed disc 2 at one end, and the main boom 1 is rotatably connected to the front end of the handle 17.
[0040] The pressing limit component is disposed on the handle 17 and is used to limit the position of the toothed disc 2;
[0041] The main boom 1 is rotatably connected to a connecting block 6 at the other end. The lower front wall of the handle 17 is provided with a first fastening hole 7. The outer wall of the main boom 1 is provided with a through hole. The connecting block 6 is provided with a second fastening hole 8. A connecting rod 9 is provided on the outer side of the main boom 1. One end of the connecting rod 9 passes through the through hole and is fastened to the second fastening hole 8. The other end of the connecting rod 9 is fastened to the first fastening hole 7.
[0042] The front end of the connecting block 6 is equipped with a uterine cup 10, and the front part of the uterine cup 10 is equipped with a front tube 11 that is connected to the connecting block 6.
[0043] As can be seen from the above, when in use, medical staff first install the connecting block 6 and the handle 17 at both ends of the main arm 1, then insert both ends of the connecting rod 9 into the first fastening hole 7 and the second fastening hole 8 respectively, and then assemble the device together. After that, the personnel can adjust the angle of the main arm 1 by rotating the main arm 1, and through the action of the connecting rod 9, the connecting block 6 is further driven to rotate, which makes it easy to adjust the position of the uterine cup 10 and the anterior tube 11. The operation is convenient and quick.
[0044] After adjusting the position, the position of the main boom 1 is limited by pressing the limiting component.
[0045] The handle 17 has an L-shaped structure design.
[0046] Specifically, the L-shaped structure design makes it easier for people to grip the handle 17.
[0047] Depend on Figure 3 , Figure 5 , Figure 6 and Figure 7 It is known that the pressing and limiting component includes an L-shaped pressure plate 3 rotatably connected to the handle 17. A locking block 4 is fixedly connected to the bottom wall of the front end of the L-shaped pressure plate 3. The locking block 4 engages with the teeth provided on the gear plate 2. The rear end of the L-shaped pressure plate 3 is connected to the handle 17 through a spring 5.
[0048] As can be seen from the above, specifically, medical staff press the L-shaped pressure plate 3 to lift the locking block 4 at the front end of the L-shaped pressure plate 3 so that it no longer engages with the teeth. This makes it easier for medical staff to rotate and adjust the angle of the main arm 1. After adjustment, the staff no longer press the L-shaped pressure plate 3, and the spring 5 returns to its original position. The locking block 4 then engages with the teeth again, thereby limiting the position of the main arm 1.
[0049] Example 2:
[0050] Handle 17;
[0051] The main boom 1 has a toothed disc 2 at one end, and the main boom 1 is rotatably connected to the front end of the handle 17.
[0052] The pressing limit component is disposed on the handle 17 and is used to limit the position of the toothed disc 2;
[0053] The main boom 1 is rotatably connected to a connecting block 6 at the other end. The lower front wall of the handle 17 is provided with a first fastening hole 7. The outer wall of the main boom 1 is provided with a through hole. The connecting block 6 is provided with a second fastening hole 8. A connecting rod 9 is provided on the outer side of the main boom 1. One end of the connecting rod 9 passes through the through hole and is fastened to the second fastening hole 8. The other end of the connecting rod 9 is fastened to the first fastening hole 7.
[0054] The front end of the connecting block 6 is equipped with a uterine cup 10, and the front part of the uterine cup 10 is equipped with a front tube 11 that is connected to the connecting block 6.
[0055] refer to Figure 3 and Figure 4 As shown, it also includes an annular plug 12 sleeved on the outside of the main boom 1. The inner wall of the annular plug 12 end tube has two clamping plates 13 symmetrically and fixedly installed. The outer wall of the main boom 1 has a clamping slot 14, and the clamping plates 13 are engaged with the clamping slot 14.
[0056] As can be seen from the above, specifically, during the assembly process, medical staff can sleeve the annular occluder 12 on the outside of the main arm 1, and further utilize the interlocking characteristics of the clamping plate 13 and the clamping slot 14 to fix the position of the annular occluder 12.
[0057] The annular occluder 12 can effectively seal the gas environment during surgery, greatly improving the airtightness of the surgical procedure.
