Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a measurable uterine manipulator. Background Art

[0002] A uterine manipulator is a medical device used to manipulate the uterus during gynecological surgery. During a total or near-total hysterectomy, your doctor may use a uterine manipulator to help stabilize and move the uterus for better surgical manipulation. This device usually consists of a long, thin handle that can be inserted into the uterus and a device attached to the end of the handle that gently grasps and manipulates the uterine wall. The use of a uterine manipulator can reduce trauma and bleeding during surgery and help shorten the duration of the operation. During the operation, the doctor will adjust the position and force of the uterine manipulator as needed to ensure the smooth progress of the operation.

[0003] Before the operation, the medical staff will make a preliminary assessment of the size of the patient's uterine cavity, and then determine an approximate slender handle, which is the extended length of the guide rod, based on their medical experience, and then perform the operation. The defect of this method is that the assessment of the patient's uterine cavity size depends entirely on the experience of the medical staff, and there is no standardized process operation or teaching. If the judgment is wrong, it will cause harm to the patient.

[0004] In view of this, it is necessary to improve the above defects. Utility Model Content

[0028] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 5As shown, the utility model provides a measurable uterine manipulator, which mainly includes a guide rod 1, a handle 3, a spiral head 6 and a uterine manipulator cup 7, wherein the rear end of the guide rod 1 is provided with a threaded portion 3 2, and a push adjustment structure 10 for pushing the guide rod 1 is provided on the periphery of the threaded portion 3 2, while the handle 3 has a cavity inside and is sleeved on the outside of the guide rod 1, and the front and rear ends thereof are respectively provided with a threaded portion 1 4 and a threaded portion 2 5;

[0031] The front end of the handle 3 is provided with a screw head 6, which is hollow inside and is also sleeved on the outside of the guide rod 1; the rear end is provided with a connection part 17, which is threadedly connected to the handle 3 through the threaded part 1 4. At the same time, the connection part 17 is provided with a through pressure hole 22, and the threaded part 1 4 is provided with a through pressure hole 1 23, and the pressure hole 1 23 and the pressure hole 2 22 overlap when in use. By inserting an additional small rod into the pressure hole 1 23 and the pressure hole 2 22 and rotating and tightening, the screw head 6 and the handle 3 can be tightened.

[0032] Next, the above-mentioned uterine lifting cup 7 is set to be hollow and sleeved on the outside of the handle 3, and the rear end of the uterine lifting cup 7 is fixedly connected to the uterine lifting cup connector 8, and the rear end of the uterine lifting cup connector 8 is threadedly connected to the hollow uterine lifting frame 9 sleeved on the outside of the handle 3; at the same time, the middle rear end of the uterine lifting frame 9 is fixedly connected to the hand-held portion 18, and the upper and lower ends of the hand-held portion 18 are fixedly connected to the fixing portion 19, and the fixing portion 19 is set to be hollow and connected to the inside of the uterine lifting frame 9, and the upper end fixing portion 19 is threadedly connected to the fixing screw 20. The bottom end of the fixing screw 20 is rotatably connected to the buffer portion 21, and the buffer portion 21 is used to abut the handle 3. When in use, the user puts the uterine lifting frame 9 on the handle 3, and then screws the fixing screw 20 into the fixing portion 19 at the upper end, and squeezes the buffer portion 21 to the outer shell of the handle 3 until it is tightened, so that the handle 3 and the uterine lifting frame 9 can be fixed.

[0033] To further explain the specific working principle of the present invention, the push adjustment structure 10 includes a threaded cover 11 disposed on the guide rod 1 at the periphery of the threaded portion 3 2, the threaded cover 11 is threadedly connected to the handle 3 through the threaded portion 2 5, and a through pressure hole 3 24 is formed on the threaded portion 2 5, and a through pressure hole 4 25 is formed on the threaded cover 11, and the pressure hole 3 24 and the pressure hole 4 25 overlap when in use. The fastening principle is the same as above, so it will not be repeated. The rear end of the threaded cover 11 is connected to the adjusting frame 12 by a bearing, and the adjusting button 13 is connected to the internal bearing of the adjusting frame 12. The outer part of the adjusting button 13 is provided with a friction part 28, which can increase the friction force of the screwing. The adjusting button 13 is threadedly connected to the guide rod 1 through the threaded part 3 2. Therefore, by screwing the adjusting button 13, the advancing distance of the guide rod 1 can be adjusted slowly and uniformly under the influence of the threaded connection to achieve safe pushing. In order to quantify the pushing distance, the utility model is located at the rear end of the adjusting frame 12. The supporting part 14 is connected to the rear end of the supporting part 14. Both sides of the rear end are provided with a telescopic scale 15 with scales. The telescopic scale 15 includes a fixed end 26 fixedly connected to both sides of the rear end of the supporting part 14. The adjacent sides of the fixed ends 26 on both sides are slidably connected with movable ends 27. The rear part of the movable ends 27 on both sides is fixedly connected to the supporting part 2 16. The rear end of the telescopic scale 15 is provided with a supporting part 2 16. At the same time, the adjustment frame 12, the support part 14 and the support part 2 16 are all arranged on the periphery of the guide rod 1, and the support part 2 16 is rotatably connected to the end of the guide rod 1.

[0034] Therefore, when in use, as the adjusting knob 13 is screwed in, the guide rod 1 moves accordingly, driving the distance between the second support part 16 and the first support part 14 to change, thereby realizing the sliding change of the movable end 27 of the telescopic scale 15 within the fixed end 26. Therefore, the user only needs to subtract the scale on the fixed end 26 of the telescopic scale 15 from the scale on the movable end 27 to know the advancement progress of the guide rod 1 and realize accurate calculation.

[0035] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0036] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
