Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a disposable balloon uterine lifter with an integrated locking structure. Background Technology

[0002] Disposable balloon uterine manipulators are primarily used for hysterectomy in laparoscopic hysteroscopic surgery. Their main functions include controlling and fixing the position of the uterus to achieve optimal surgical field exposure. It consists of a balloon, manipulator rod, manipulator cup, cup holder, and handle. The manipulator cup and cup holder can slide back and forth along the manipulator rod. After sliding to the predetermined position during surgery, the cup holder needs to be fixed to support the manipulator cup, allowing the surgeon to perform hysterectomy in the designated location for a smooth procedure. However, in existing technologies, the cup holder and locking structure are two components with non-fixed relative positions, leading to inconvenient fixation and inaccurate positioning, thus affecting surgical efficiency.

[0003] For example, a Chinese invention patent application discloses a tumor-preventing implantation uterine lifter [application number: 202110568063.7]. This invention patent application includes a uterine lifter cup, a central sleeve, and a central guide rod. The uterine lifter cup is provided with a central sleeve that penetrates through the bottom of the uterine lifter cup. The negative pressure suction device is connected to the cavity between the uterine lifter cup and the central sleeve located inside the uterine lifter cup through a negative pressure pipe. The central guide rod penetrates through the central sleeve, and the operating end of the central guide rod is connected to the corresponding position of the central sleeve through a positioning device.

[0004] This invention patent application has the advantages of effectively improving the fixation and stability of the cervix, reducing operation time, preventing the spread and implantation of tumor cells, and reducing the risk of cross-infection before and after the operation, but it still does not solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a disposable balloon uterine lifter with an integrated locking structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A disposable balloon uterine lifter with an integrated locking structure includes a handle and a uterine lift rod fixedly connected to the handle. The uterine lift rod is provided with a balloon, and a uterine lift cup is slidably connected to the uterine lift rod. It also includes a cup holder assembly located between the uterine lift cup and the handle. The cup holder assembly is slidably connected to the uterine lift rod, and sliding the cup holder assembly allows the end of the cup holder assembly to abut against the bottom of the uterine lift cup. A locking component is also fixedly connected to the cup holder assembly. Rotating the locking component allows the end of the locking component to move closer to or away from the uterine lift rod.

[0008] In the aforementioned disposable balloon uterus lifter with an integrated locking structure, the cup support assembly includes a sleeve with an internal through hole. The uterus lifter rod passes through the sleeve via the through hole. A locking assembly is fixedly connected to one end of the sleeve. Rotating the locking assembly allows the end of the locking assembly to extend into the through hole and press against the surface of the uterus lifter rod. A support member is fixedly connected to the other end of the sleeve, and the end of the support member abuts against the bottom of the uterus lifter cup.

[0009] In the aforementioned disposable balloon uterine lifter with an integrated locking structure, the side of the lifting member near the uterine cup is a planar lifting surface, and the diameter of the lifting surface is more than a multiple of the diameter of the sleeve.

[0010] In the aforementioned disposable balloon lifting device with an integrated locking structure, the side of the lifting component is a sealing surface, and the sealing surface is a frustoconical surface that is smaller at the top and larger at the bottom.

[0011] In the aforementioned disposable balloon uterine lifter with an integrated locking structure, the locking assembly includes a mounting base fixedly connected to the end of the sleeve, the mounting base having a mounting hole, and a fixing bolt threadedly engaging with the mounting hole.

[0012] In the aforementioned disposable balloon uterine lifter with an integrated locking structure, the end of the sleeve away from the lifting member further includes at least two mounting surfaces located in adjacent positions. The inner wall of the mounting base has mating surfaces adapted to the mounting surfaces, and the mating surfaces are arranged in a one-to-one correspondence with the mounting surfaces.

[0013] In the aforementioned disposable balloon uterus lifter with an integrated locking structure, the locking assembly further includes a connecting strap made of flexible material, one end of which is connected to a fixing bolt and the other end of which is connected to a mounting base.

[0014] In the aforementioned disposable balloon uterus lifter with an integrated locking structure, the fixing bolt is provided with at least two mutually parallel limiting eaves that protrude from the surface of the fixing bolt, and there is a limiting space between the two limiting eaves. One end of the connecting strap is sleeved in the limiting space.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. The locking component of this utility model is fixedly installed on the cup holder component, so that the relative position of the locking component and the cup holder component will not change during use. There is no need to worry about whether the locking component and the cup holder component are completely fitted. Simply slide the cup holder component to the predetermined position to lock it quickly, which improves the accuracy of the locking position and simplifies the operation.

[0017] 2. This utility model has a simple structure, is easy to assemble, and is suitable for large-scale promotion and use. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, a disposable balloon uterus lifter with an integrated locking structure includes a handle 1 and a lifting rod 2 fixedly connected to the handle 1. The lifting rod 2 is provided with a balloon 3. A lifting cup 4 is slidably connected to the lifting rod 2. It also includes a cup holder assembly 5 located between the lifting cup 4 and the handle 1. The cup holder assembly 5 is slidably connected to the lifting rod 2, and sliding the cup holder assembly 5 allows the end of the cup holder assembly 5 to abut against the bottom of the lifting cup 4. A locking assembly 6 is also fixedly connected to the cup holder assembly 5. Rotating the locking assembly 6 allows the end of the locking assembly 6 to move closer to or away from the lifting rod 2.

[0026] In this invention, during use, medical personnel slide the cup holder assembly 5 to push the uterine cup 4, thereby moving the uterine cup 4 to a predetermined position. At this point, the locking assembly 6 locks the cup holder assembly 5 in place, eliminating the need to adjust the relative position between the locking assembly 6 and the cup holder assembly 5. Therefore, the locking assembly 6 is fixedly mounted on the cup holder assembly 5, ensuring that the relative position of the locking assembly 6 and the cup holder assembly 5 remains unchanged during use. There is no need to worry about whether the locking assembly 6 and the cup holder assembly 5 are perfectly aligned; simply sliding the cup holder assembly 5 to the predetermined position quickly locks it in place, improving the accuracy of the locking position and simplifying the operation.

[0027] Combination Figure 2 and Figure 3As shown, the cup holder assembly 5 includes a sleeve 52 with an internal through hole 51. The uterine lifting rod 2 passes through the sleeve 52 through the through hole 51. One end of the sleeve 52 is fixedly connected to a locking assembly 6. Rotating the locking assembly 6 allows the end of the locking assembly 6 to extend into the through hole 51 and press against the surface of the uterine lifting rod 2. The other end is fixedly connected to a support member 53. The end of the support member 53 abuts against the bottom of the uterine lifting cup 4.

[0028] Preferably, the side of the lifting member 53 closest to the uterine cup 4 is a planar lifting surface 54, and the diameter of the lifting surface 54 is more than twice the diameter of the sleeve 52. This ensures that there is a large contact area between the lifting member 53 and the uterine cup 4 during lifting, thus ensuring the stability of the lifting process.

[0029] Preferably, the side of the support member 53 is a sealing surface 55, which is a frustoconical surface that is smaller at the top and larger at the bottom. During the operation, the sealing surface 55 is in close contact with the vaginal wall to achieve a sealing effect, ensuring that the pneumoperitoneum does not leak and maintaining a stable laparoscopic operating space. The design of the sealing surface 55 as a frustoconical surface that is smaller at the top and larger at the bottom can also play a certain guiding role to facilitate surgical operations.

[0030] Combination Figure 2 and Figure 4 As shown, the locking assembly 6 includes a mounting base 61 fixedly connected to the end of the sleeve 52. The mounting base 61 has a mounting hole 62, and the fixing bolt 63 is threadedly engaged with the mounting hole 62.

[0031] Preferably, the end of the sleeve 52 away from the supporting member 53 further includes at least two adjacent mounting surfaces 56. The inner wall of the mounting base 61 has mating surfaces 64 adapted to the mounting surfaces 56, and the mating surfaces 64 and mounting surfaces 56 are provided in a one-to-one correspondence. The mating of the mating surfaces 64 and the mounting surfaces 56 can play a role in quick positioning during the installation of the mounting base 61 to the end of the sleeve 52. The mounting base 61 and the sleeve 52 can be fixed by fast-drying adhesive.

[0032] Combination Figure 2 and Figure 5 As shown, the locking assembly 6 also includes a connecting strap 65 made of flexible material. One end of the connecting strap 65 is connected to the fixing bolt 63, and the other end is connected to the mounting base 61. Using the connecting strap 65 to connect the mounting base 61 and the fixing bolt 63 can avoid the problem of small surgical instruments having many parts, which makes the parts easy to lose and inconvenient to store.

[0033] Preferably, the fixing bolt 63 is provided with at least two mutually parallel limiting protrusions 66 that protrude from the surface of the fixing bolt 63, and a limiting space 67 is provided between the two limiting protrusions 66. One end of the connecting strap 65 is sleeved in the limiting space 67. The limiting effect of the two limiting protrusions 66 ensures that after the connecting strap 65 is sleeved on the fixing bolt 63, its position along the axis of the fixing bolt 63 is relatively fixed, and it will not slide up and down a large distance.
