Description

Technical Field

[0001] The utility model relates to the technical field of submucosal myoma graspers, in particular to a submucosal myoma grasper. Background Art

[0002] Submucosal fibroids are intramural fibroids that grow into the uterine cavity, protrude into the uterine cavity, and are in direct contact with the mucosal layer. They account for about 10% of cases. This tumor can gradually enlarge and deform the uterine cavity, and is often connected to the uterus by a pedicle. If the pedicle is long, it can block the cervical opening or prolapse into the vagina. Fibroids grow in the cervix of the uterus. Due to their low growth location, they can be embedded in the pelvic cavity, causing compression symptoms. Surgical removal is difficult and can easily damage the ureter and bladder. Uterine fibroids are often multiple, and the above different types of fibroids can occur simultaneously in the same uterus, which is called multiple uterine fibroids. During the hysteroscopic resection of submucosal uterine fibroids, if the fibroids are small and have a pedicle, ring electrode resection can be selected. The pedicle of the myoma is separated from the uterine wall and then taken out. Existing submucosal myomas are often removed with oval forceps. For internal protruding myomas without pedicles, a ring electrode can be selected to cut them into pieces and then removed. When removing them, the oval forceps are directly inserted into the uterine cavity, and then the myoma and fragments are taken out. The traditional oval forceps have a limited opening angle in the uterine cavity, a small forceps surface, and blind removal. The depth of entry is different each time, which is easy to be too deep or too shallow, often resulting in difficulty in removing the myoma and its fragments. Repeated entry into the uterine cavity leads to prolonged operation time, increased chances of intraoperative and postoperative bleeding, uterine perforation and damage to surrounding organs, overhydration syndrome and other complications. For this reason, we propose a submucosal myoma grasper. Utility Model Content

[0028] The working principle of a submucosal fibroid grabber provided by the present invention is as follows: when performing the grabbing work, the operator holds the handle 1 and slowly moves the lower end of the grabber into the uterine cavity. When the green insertion mark 451 is located at the vaginal opening, the grabber has entered the uterine cavity and the operator needs to operate the grabber more slowly and steadily to go deeper. When the red insertion mark 451 is located at the vaginal opening, the advancement is stopped. Then the operator holds the handle 3 and starts the grabbing work, pushing the slip ring 47, and the slide column 2 also moves accordingly. The spring 2 46 is compressed by force until the right side of the slip ring 47 reaches the lower end of the limit groove 48. The grabbing device is pushed out and then the slip ring 47 is deflected so that the slip ring 47 enters the lower end front side of the limit groove 48. The slide column 2 is fixed and then pushes the push rod 41. The spring 1 42 is compressed by force and the push rod 41 is displaced. The multiple claws 43 are squeezed through the connecting rod 44 so that the multiple claws 43 opens. At this time, as the push rod 41 moves, the green push mark 452, the yellow push mark 452 and the orange push mark 452 enter the slide groove in turn and are covered by the upper end of the slide column 2. At this time, the multiple claws 43 slowly open. When the red push mark 452 is flush with the upper end of the slide column 2, the conductive head 454 contacts the contact head 1 455, and the warning light 456 is powered on and flashes, reminding the operator that the safety limit has been reached. If the push rod 41 is continued to be pushed, when the black push mark 452 is flush with the upper end of the slide column 2, the conductive head 454 contacts the contact head 2 457, and the buzzer 458 sounds, reminding the operator that the safety limit has been exceeded and it is necessary to quickly return to the original position. Then the push rod 41 is slowly returned to its original position, the spring 1 42 is not under force and rebounds, and the multiple claws 43 close to clamp the fibroids and its fragments. Then the grasper is slowly pulled out to complete the clamping of the submucosal fibroids.

[0029] It is worth noting that the buzzer 458 disclosed in the above embodiment is an AD16-22M / K312823 buzzer.

[0030] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
