Description

Technical Field

[0001] The invention relates to the field of laparoscopic surgery, and in particular to a vaginal extraction device for laparoscopic hysterectomy. Background Art

[0002] In the field of gynecological laparoscopic surgery, hysterectomy is an important means of treating a variety of uterine diseases (such as uterine fibroids, adenomyosis, cervical cancer, etc.). With the continuous development of medical technology, laparoscopic surgery has gradually become one of the common methods of hysterectomy due to its advantages of less trauma and faster recovery. As an auxiliary means, vaginal extraction can further reduce abdominal incisions, reduce surgical trauma, and improve the patient's quality of life after surgery.

[0003] However, the existing laparoscopic hysterectomy and vaginal retrieval surgery still faces many challenges. During the operation, the uterus is located deep in the pelvic cavity, adjacent to important organs such as the bladder and rectum, making it difficult to expose the surgical field of view and obtain operating space. In addition, due to the abnormal enlargement of the diseased uterus, it is difficult to remove it from the vagina.

[0004] When it comes to cutting and removing uterine tissue, traditional cutting tools and methods have certain limitations. When cutting uterine tissue, it is difficult to evenly and quickly divide the uterus into small pieces that are easy to remove with the commonly used scalpels or electrosurgical cutting instruments. This not only prolongs the operation time and increases the risk for patients on the operating table, but may also cause residual uterine tissue or difficulty in removal due to uneven cutting, leading to complications such as postoperative bleeding and infection.

[0005] Traditional surgical instruments often cannot effectively prevent interference from surrounding organs on the surgical area. For example, when dealing with the uterus, the prolapsed bladder above it can easily block the surgical field of view, increasing the risk of accidental injury to the bladder, while also limiting the doctor's operating range and accuracy on the uterus.

[0006] In addition, the existing instrument connection structure is difficult to ensure stable coordination between the various parts of the instrument during uterine cutting and other operations. For example, during the cutting process, the shaking or displacement of the instrument may lead to loss of control of the cutting depth and range, causing unnecessary damage to the blood vessels and nerves around the uterus, seriously affecting the safety of the operation and the treatment effect.

[0007] Therefore, it is necessary to provide a new vaginal retrieval device for laparoscopic hysterectomy to solve the above technical problems. Summary of the invention

[0018] Compared with the related art, the vaginal retrieval device for laparoscopic hysterectomy provided by the present invention has the following beneficial effects:

[0019] 1. The present invention effectively blocks the prolapsed bladder above through the main baffle on the outer ring frame to prevent it from interfering with the surgical area. At the same time, the two side baffles can be expanded outward, significantly expanding the operable area in the vagina. This allows the surgical instruments to perform the operation more smoothly, and the doctor has a clearer field of vision during the operation, and can accurately identify the boundary between the uterine tissue and the surrounding organs, reducing the surgical risks caused by limited field of vision or insufficient operating space, such as accidental injury to other tissues and organs. It improves the success rate of the operation, helps the patient recover quickly after the operation, and reduces the incidence of surgical complications;

[0020] 2. The present invention realizes the fastening and locking between the outer tube and the center rod through ingenious design. After the center rod is pushed and extended out of the outer tube, the outer tube and the center rod can be firmly fixed together by means of the cooperation of the fastening cap, the limiting ring frame, and the fastening arc piece. This stable connection structure effectively prevents the shaking or displacement of the center rod during the cutting operation, and ensures the position accuracy of the built-in blade and the elastic cutting wire when cutting uterine tissue. The doctor can control the cutting depth, angle, and range more stably and accurately, thereby improving the quality of hysterectomy surgery, making the surgical incision more neat and standardized, facilitating the healing of postoperative wounds, and reducing the occurrence of adverse events such as tissue tearing and bleeding caused by unstable surgical instruments;

[0021] 3. The present invention pulls the yellow line to drive the rope end arranged in a ring at one end to be continuously tightened in the secondary ring buckle, driving the cover mouth of the plastic cover to be tightened quickly. The plastic cover can well wrap the uterus to be removed, and then pull the pull ring to drive the pull rope to slide relative to the cavity inside the center rod. The rope end arranged in a ring at one end of the pull rope is continuously tightened in the main ring buckle, driving multiple elastic cutting wires to separate from the inner wall of the plastic cover. The multiple elastic cutting wires then completely and evenly decompose the uterine tissue into multiple small pieces. This cutting method is more efficient than the traditional cutting method and can complete the processing of uterine tissue in a shorter time. Small pieces of uterine tissue are easier to remove through the vagina, reducing the time for taking objects during surgery, effectively reducing artificial damage to the vaginal wall and bacterial and viral contamination in the abdominal cavity, shortening the operation time, alleviating the patient's pain, and also facilitating the recovery of the patient's body functions after surgery.

[0022] 4. The present invention increases the brightness inside the vagina by utilizing the fluorescent layer on the inner walls of the two side baffles, thereby significantly improving the visibility of the surgical area and effectively preventing accidental injury to other tissue parts due to insufficient light during the surgical operation. The stable instrument structure and precise cutting operation effectively reduce accidental injuries during the operation, optimize the surgical field of view, and improve the safety of patients during the operation.
