Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a bilateral uterine horn distance measuring device. Background Technology

[0002] During gynecological examinations and surgeries, understanding the specific anatomical structure of the uterus is crucial for accurate diagnosis and treatment. In particular, measuring the distance between the two uterine horns is of great significance for the diagnosis of uterine malformations and infertility, as well as the planning and implementation of certain surgeries (such as endometrial lesion surgery and myomectomy). However, current methods for measuring the distance between the two uterine horns have certain limitations, mainly in the following aspects:

[0003] 1. Limitations of Imaging Methods: While commonly used imaging methods such as ultrasound, MRI, and CT scans can provide image information of the uterus, they have certain errors in accurately measuring the distance between the bilateral uterine horns. These imaging methods rely on image resolution and the doctor's subjective judgment, which limits the reliability and accuracy of the measurement results.

[0004] 2. Poor real-time performance: Most existing imaging measurement methods cannot provide real-time data on the distance between the bilateral uterine horns during surgery. This means that during surgery, doctors need to rely on preoperative image data for judgment, and the lack of real-time, accurate data support may affect the precision and effectiveness of the surgery.

[0005] 3. Complex Operation: Existing measurement equipment and methods require specialized skills and experience, making them complex to operate. This not only increases the workload of doctors but also extends the time and difficulty of surgeries. For some primary healthcare institutions and inexperienced doctors, using these devices for accurate measurements presents certain challenges.

[0006] 4. Highly invasive: Some measurement methods require invasive procedures using hysteroscopy or other instruments, increasing patient discomfort and surgical risks. These invasive procedures can not only lead to infection and bleeding but also cause psychological stress for the patient.

[0007] 5. Lack of dedicated equipment: There is a lack of dedicated equipment on the market for measuring the distance between the two uterine horns. Although some existing equipment can measure indirectly, it is not designed for this purpose, and its measurement accuracy and ease of operation are not ideal.

[0008] In summary, existing technologies have many shortcomings in measuring bilateral uterine horn distance. There is an urgent need for a dedicated measuring device that is easy to operate, highly accurate, real-time, and low-invasive to meet clinical needs and improve treatment outcomes.

[0009] This invention addresses these problems by providing an improved bilateral uterine horn distance measurement device, aiming to overcome the shortcomings of existing technologies and provide a more accurate, convenient, and safe measurement tool for clinical use. Utility Model Content

[0051] In one embodiment, the operating part 3 has a transmission cavity 301, and two sets of opposing meshing blocks 302 are slidably connected in the transmission cavity 301. A transmission gear 303 is rotatably connected in the transmission cavity 301 between the meshing blocks 302. The transmission gear 303 is respectively engaged with the meshing groove on the opposite side of the meshing block 302. Push rods 304 are fixedly connected to the ends of the meshing blocks 302.

A locking rod 402 is slidably connected in the locking hole 401. One end of the locking rod 402 passes through the rotating groove 305 and abuts against the outer periphery of the operating wheel 306. The outer periphery of the operating wheel 306 is provided with helical teeth. The edge of the locking rod 402 engages with the helical teeth, preventing the operating wheel 306 from rotating, thereby relatively restricting the transmission gear 303. The other end of the locking rod 402 is connected to... The third spring 403 is in contact with the locking hole 401.

One end of the movable rod 405 passes through the sliding groove hole 406 and is fixedly connected to the operating block 407.

[0053] The specific working principle of this utility model is as follows:

[0054] 1. In use, first insert the hysteroscope into the uterus and ensure a clear view through the hysteroscope's endoscopic display system. Next, the operator inserts the anterior arm measuring component 1 of the uterine horn measuring device into the uterus through the instrument channel of the hysteroscope. With the assistance of the endoscopic display system, the operator rotates the operating wheel 306 on the operating unit 3, at which time the measuring arms of the anterior arm measuring component 1 and the posterior arm measuring component 2 will open synchronously.

[0055] 2. As the operating wheel 306 rotates, the transmission gear 303 in the transmission cavity 301 drives the meshing block 302 to move, thereby pushing the push rod 304 to slide, which in turn pushes the first sliding block 102 and the second sliding block 202 forward, compressing the first spring 103 and the second spring 203. The forward movement of the first sliding block 102 and the second sliding block 202 causes the first sliding rod 105 and the second sliding rod 205 to slide within the first outer sleeve 104 and the second outer sleeve 204 respectively, pushing the connecting rod and the rotating arm to rotate, causing the first measuring arm 109 and the second measuring arm 209 to open.

[0056] 3. When the current extended distance of the measuring arm is consistent with the uterine angle distance, the operator can read the position value of the rear measuring arm through the scale 5, which is the uterine angle distance. After reading, the operator slides the operating block 407 on the operating part 3, and the front and rear measuring arms automatically retract under the action of the first spring 103 and the second spring 203.

[0057] 4. Finally, the forearm measuring component 1 is removed from the instrument channel of the hysteroscope to complete the measurement of the uterine horn distance. The entire process ensures the accuracy of the measurement and the simplicity of the operation, reduces the operation time, and improves the measurement efficiency.

[0058] This invention enables precise measurement of the uterine horn distance, making it suitable for widespread clinical application in uterine-related surgeries and examinations.
