Description

Technical Field

[0001] The present invention belongs to the technical field of gynecological clinical practice, and specifically relates to a device for resection of submucous myomas under hysteroscopy. Background Art

[0002] Uterine fibroids are common gynecological tumors, generally manifested as clinical symptoms such as uterine bleeding, abdominal mass, pain, increased leucorrhea, etc. If not treated in time, it may lead to the deterioration of the tumor, seriously endangering the physical and mental health of patients. Uterine fibroids are multiple and can grow in any part of the uterus. The traditional treatment method for uterine fibroids is laparotomy, but this method has greater risks and traumas, slow postoperative recovery, and will have a certain impact on the fertility of patients. Therefore, it has gradually been replaced by hysteroscopy and laparoscopy with less damage, faster recovery, and less impact on organs. Currently, hysteroscopic surgery and laparoscopic surgery are two common surgical methods for resection of uterine fibroids, which can be used alone or in combination. The combined hysteroscope and laparoscope can combine the characteristics of the two surgical methods and have better treatment advantages for multiple uterine fibroids with a wider spread of fibroids;

[0003] In the prior art, submucous myomas under hysteroscopy can be removed by electrocision. Currently, when performing the operation of resection of submucous myomas under hysteroscopy, the vagina needs to be dilated through a dilator. The existing dilators are generally in the shape of a duckbill, and the dilator is opened by manual force. It is difficult to master the dilatation force. While achieving dilatation, it will also cause obstacles for medical staff during the resection of myomas. The electrocision cannot move and cut flexibly and fixed-point in the uterine cavity, which may make some myomas difficult to detect, resulting in incomplete resection of myomas and causing some myomas to remain.

[0039] Working principle and usage process of the present invention: By placing the expansion plate 22 at the vaginal part of the patient, then pulling the push rod 27 on the outer shell plate 21, it drives the rectangular cylinder 29 to move horizontally. The movement of the rectangular cylinder 29 will drive the semi-circular plate 230 and the hinge plates 231 hinged at both ends of the semi-circular plate 230. Pulling the hinge plates 231 can drive the two gear rotating plates 232 to rotate, thereby synchronously driving the two tooth plates 233 to translate in opposite directions on the sliding plate 234, achieving the purpose of vaginal dilation. When dilating, it is not necessary to use too much hand strength of medical staff. Just push and pull the push rod 27. Then pull down the collar 26 installed on the push rod 27, so that the T-shaped block 25 on the collar 26 is engaged with two of the clamping rods 24 installed on the chute 23, and immediate limit fixation can be carried out. Then, with the medical staff holding the bottom end of the outer shell plate 21, the electrocision rod 11 is inserted into the patient's uterus through the rectangular cylinder 29. The patient's uterus has been inflated before the operation, which is an existing technology, enabling the electrocision rod 11 to enter easily. The myoma cutting process can be completed with one hand. Through the camera lens 12 on the electrocision rod 11, the medical staff can observe the internal situation of the uterus in real time. By the medical staff holding the handle 18, the electrocision rod 11 can be driven to move and rotate in multiple directions in the uterus through the turntable 14. The turntable 14 will rotate at a fixed point at one end of the outer shell plate 21, thereby driving the electrocision rod 11 to move locally and flexibly in the rectangular cylinder 29. When the electrocision rod 11 cuts the myoma, during the continuous downward movement at the incision, it drives the expansion ring 13 to move downward, expanding the incision of the lower myoma, facilitating the observation and cutting process, and avoiding incomplete resection of the myoma and causing partial myoma residue.
