Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device for lifting ovarian cysts during laparoscopic surgery. Background Technology

[0002] Ovarian cysts are sac-like structures that form inside or on the surface of the ovary, containing fluid or semi-solid substances. As a common gynecological condition, the harm caused by ovarian cysts should not be ignored. Larger ovarian cysts may cause lower abdominal pain and a feeling of heaviness, affecting the patient's quality of life. Moreover, ovarian cysts may affect the normal function of the ovary, leading to abnormal ovulation and thus reducing the chances of conception. Although most ovarian cysts are benign, there is a certain risk of malignancy; especially cysts that are long-standing, rapidly growing, or accompanied by symptoms such as ascites, have a relatively higher possibility of malignancy. To accurately and safely remove ovarian cysts, current surgical procedures typically use laparoscopic surgery to peel or remove the cysts. Laparoscopic surgery not only provides a clear surgical field and reduces surgical risks, but also has the advantages of minimal trauma, less bleeding, and faster postoperative recovery. However, during laparoscopic surgery, due to the limited surgical space and the need to maintain a clear surgical field, lifting and fixing the ovarian cyst becomes a key technique in the surgery. Traditional lifting methods may have problems such as inconvenience in operation and unstable fixation, while ovarian cyst lifting devices specifically designed for laparoscopic surgery provide a more convenient and stable solution.

[0003] In the prior art, for example, a patent application with application number CN202021434599.7 discloses a device for single-port laparoscopic ovarian cyst surgery, which includes an inner tube, an outer tube, a storage bag, a closure strap, and a guide block. The closure strap includes a strap body and a lock head. The lock head is located inside the front end of the inner tube, and the guide block is fixed inside the inner tube and located behind the lock head. One end of the strap body is fixed to the lock head, and the other end passes through the lock head and the guide block in sequence, is located inside the inner tube, and extends to the outer side of the tail end of the inner tube. Part of the strap body forms a closure ring outside the front end of the inner tube. The storage bag is a cylindrical bag with openings at both the top and bottom. The opening at one end of the storage bag is fitted onto the closure ring. The outer tube is fitted outside the inner tube. The storage bag and the closure ring are folded and placed in the cavity at the front end of the outer tube. This device has a simple structure and is easy to operate. It can solve problems such as difficulty in lifting ovarian cysts and cyst rupture contaminating the abdominal cavity leading to tumor implantation in single-port laparoscopic surgery. It is suitable for industrial production and market application.

[0004] While this device can lift ovarian cysts, the cyst removal process requires the use of a storage bag, which has limited space, making cyst removal inconvenient and affecting the surgical progress. Furthermore, the device does not secure the cyst during lifting, increasing the difficulty of removal and impacting the effectiveness. Therefore, a novel ovarian cyst lifting device is needed to address these issues.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] In view of at least one of the above-mentioned technical problems, this disclosure provides a laparoscopic ovarian cyst traction device, which aims to solve the problems existing in the prior art.

[0007] According to one aspect of this disclosure, a laparoscopic ovarian cyst lifting device is provided, comprising a support tube, a limiting groove symmetrically disposed within the support tube, support blocks installed at both ends within the support tube, a positioning mechanism movably engaged in the limiting groove, and a lifting mechanism movably mounted on the positioning mechanism; the lifting mechanism includes a lifting plate movably mounted on the positioning mechanism, a driving block fixed to the front end of the lifting plate, a lifting ring rotatably mounted on the rear end of the lifting plate, and a storage bag rotatably mounted on the rear end of the lifting plate, the storage bag being located below the lifting ring, and the driving block extending outside the support tube.

[0008] Furthermore, the positioning mechanism includes a movable plate, movable blocks on both sides of the movable plate, movable side plates perpendicularly fixed on the movable plate, and positioning blocks installed at the bottom of the movable plate. Multiple positioning plates are also provided inwardly and at equal intervals on the movable side plates.

[0009] Furthermore, the positioning block is located between the support blocks, and a control shaft is also inserted through the positioning block. The control shaft is also inserted through the support block, and the front end of the control shaft extends outside the support tube.

[0010] Furthermore, the lifting mechanism also includes a plurality of side protrusions fixed outward and at equal intervals on the lifting plate, a connecting rod fixed parallel to the lifting plate on the side protrusions, and a return spring sleeved on the connecting rod. The positioning plate is movably sleeved on the connecting rod, and the return spring is located between the side protrusions and the positioning plate.

[0011] Furthermore, the lifting mechanism also includes a linkage shaft rotatably mounted on the rear end of the lifting plate, a connecting block fixedly sleeved on the linkage shaft, and a storage block fixed at the lower end of the linkage shaft. The lifting ring is fixed to the free end of the connecting block, and the storage bag is fixed to the free end of the storage block.

[0012] Furthermore, the lifting mechanism also includes a receiving block fixed inward on the connecting block, a connecting frame rotatably mounted on the receiving block, a limiting block rotatably mounted inward on the front end of the lifting plate, and an adjusting rod passing through the limiting block. The rear end of the adjusting rod is rotatably locked on the connecting frame, and the front end of the adjusting rod extends outside the support tube.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] 1. The device of this application uses a lifting ring to fix the ovarian cyst. First, the rotating support block drives the positioning mechanism and the lifting mechanism to move synchronously. Then, the lifting ring is extended by pressing the drive block and the ovarian cyst is fixed on the lifting ring. Finally, the lifting ring is retracted and reset by the return spring, thereby realizing the lifting of the ovarian cyst. The arc-shaped design of the lifting ring can realize the lifting and limiting fixation of the ovarian cyst, which provides convenience for the surgeon.

[0015] 2. The lifting ring in this device is designed to be rotatable. By rotating the angle adjustment rod and limiting the position of the limiting block, the lifting ring can be indirectly rotated to a certain angle. The surgeon can rotate the lifting ring according to the location of the cyst to ensure the lifting and fixation effect. Moreover, since the lifting ring rotates around the linkage shaft, and the storage bag is also connected to the linkage shaft, the lifting ring and the storage bag rotate synchronously. This not only facilitates the surgeon's cyst removal work, but also allows the storage bag to collect the fluid that flows out during the operation, preventing the fluid from contaminating the abdominal cavity and ensuring the safety of the operation.

In order to better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] This example discloses a laparoscopic ovarian cyst traction device. (See also...) Figures 1 to 8 The device includes a support tube 1, a limiting groove 12 symmetrically arranged in the support tube 1, a support block 11 installed at both ends in the support tube 1, a positioning mechanism 3 movably locked in the limiting groove 12, and a lifting mechanism 2 movably installed on the positioning mechanism 3. The lifting mechanism 2 includes a lifting plate 21 movably installed on the positioning mechanism 3, a driving block 22 fixed to the front end of the lifting plate 21, a lifting ring 23 rotatably installed on the rear end of the lifting plate 21, and a storage bag 26 rotatably installed on the rear end of the lifting plate 21. The storage bag 26 is located below the lifting ring 23, and the driving block 22 extends outside the support tube 1.

[0028] The positioning mechanism 3 includes a movable plate 31, movable blocks 311 on both sides of the movable plate 31, movable side plates 32 vertically fixed on the movable plate 31, and positioning blocks 34 installed at the bottom of the movable plate 31. Multiple positioning plates 33 are also provided inwardly and at equal intervals on the movable side plates 32. The positioning blocks 34 are located between the support blocks 11, and a control shaft 35 passes through the positioning blocks 34. The control shaft 35 also passes through the support blocks 11, and its front end extends outside the support tube 1.

[0029] The lifting mechanism 2 also includes multiple side protrusions 211 fixed outward and equidistantly on the lifting plate 21, a connecting rod 213 fixed parallel to the lifting plate 21 on the side protrusions 211, and a return spring 212 sleeved on the connecting rod 213. The positioning plate 33 is movably sleeved on the connecting rod 213, and the return spring 212 is located between the side protrusions 211 and the positioning plate 33. The lifting mechanism 2 also includes a linkage shaft 25 rotatably passing through the rear end of the lifting plate 21, a connecting block 231 fixedly sleeved on the linkage shaft 25, and a storage block 261 fixed at the lower end of the linkage shaft 25. The lifting ring 23 is fixed to the free end of the connecting block 231, and the storage bag 26 is fixed to the free end of the storage block 261. The lifting mechanism 2 also includes a receiving block 27 fixed inward on the connecting block 231, a connecting frame 28 rotatably mounted on the receiving block 27, a limiting block 29 rotatably mounted inward on the front end of the lifting plate 21, and an adjusting rod 24 passing through the limiting block 29; the limiting block 29 is also provided with an internal thread, and the adjusting rod 24 is also provided with an external thread, and the limiting block 29 is threadedly connected to the adjusting rod 24; the rear end of the adjusting rod 24 is rotatably locked on the connecting frame 28, and the front end of the adjusting rod 24 extends outside the support tube 1.

[0030] When implementing the device of this application, the lifting device, laparoscope, and related instruments are inserted into the abdominal cavity through a small incision in the patient's abdomen, and the lifting device is fixed. Then, the location, size, and shape of the ovarian cyst are clearly observed using the imaging system of the laparoscope. After confirmation, the control shaft 35 is manually rotated. Under the limitation of the positioning block 34, the positioning mechanism 3 drives the lifting mechanism 2 to extend outward along the limiting groove 12 until the lifting ring 23 is completely extended from the support tube 1 and the storage bag 26 unfolds in the abdominal cavity. Stop the rotation of the control shaft 35; then, according to the location and direction of the ovarian cyst, manually rotate the angle adjustment rod 24. Under the limit of the internal thread on the limit block 29, the angle adjustment rod 24 pulls the lifting ring 23 to rotate through the rotatable connecting frame 28 and the rotatable connecting block 231. Since the storage bag 26 is fixedly connected to the linkage shaft 25 through the storage block 261, the storage bag 26 rotates synchronously while the lifting ring 23 rotates; when the lifting ring 23 rotates to a certain angle, stop the rotation of the angle adjustment rod 24. Next, the surgeon presses the drive block 22 with their hand, causing the connecting rod 213 to move downward along the positioning plate 33, and simultaneously driving the lifting mechanism 2 to move downward, so that the lifting ring 23 continuously extends downward. During this time, the surgeon uses the other hand to hold a clamp to assist in lifting the ovarian cyst, so that the lifting ring 23 fits under the ovarian cyst through its notch, and the ovarian cyst is confined within the lifting ring 23. Then, the clamp is released, and the pressure on the drive block 22 is slowly released manually. At this time, under the pushing action of the return spring 212, the side protrusion 211 indirectly drives the lifting ring 23 to retract and move through the lifting plate 21. The lifting ring 23 drives the ovarian cyst that is stuck on it to move and lifts the ovarian cyst to a suitable position. The lifting ring 23 is designed with an arc shape, which ensures that the ovarian cyst is confined and fixed within the lifting ring 23. Next, the surgeon can remove the ovarian cyst. During the removal process, the storage bag 26 located below the lifting ring 23 prevents any fluid leakage from contaminating the abdominal cavity. After removal, the ovarian cyst is treated and the storage bag 26 is cleaned. After cleaning, the angle adjustment lever 24 and control shaft 35 are rotated sequentially to return the lifting ring 23 and storage bag 26 to their original angles. Under the limit of the positioning mechanism 3, the lifting ring 23 and storage bag 26 are stored inside the support tube 1. Finally, the lifting device can be removed. The operation is simple and practical. Utilizing the rotatable lifting ring 23 to drive the synchronously rotating storage bag 26 ensures a lifting effect while facilitating the removal of the ovarian cyst, making it highly practical.
