Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a gynecological uterine fibroid stripping device. Background Art

[0002] Uterine fibroids are benign tumors formed by monoclonal proliferation of smooth muscle cells in the myometrium. They are the most common pelvic tumors in women and one of the most common tumors in the human body. The treatment of uterine fibroids must be comprehensively considered based on the patient's age, fertility requirements, symptoms, and size of the fibroids.

[0003] Treatments include follow-up observation, drug therapy, and surgical treatment.

[0004] Follow-up observation: For patients with asymptomatic or mildly symptomatic fibroids, regular follow-up examinations can be performed, approximately every 3 to 6 months. Drug treatment: Suitable for patients with mild symptoms, near menopause, or whose general condition is not suitable for surgery.

[0005] Commonly used drugs include gonadotropin-releasing hormone analogs, androgens, progestins, etc. However, drug treatment is often ineffective and is prone to relapse after discontinuation of medication, so long-term medication is not recommended.

[0006] Surgical treatment: It is the only way to eradicate uterine fibroids. Depending on the patient's specific situation, myomectomy or hysterectomy can be selected. Hysterectomy is suitable for older patients who do not require to retain fertility or suspected of malignant transformation, so myomectomy is generally used and is suitable for patients who wish to retain fertility.

[0007] The general steps of myomectomy are: the patient takes an appropriate position and receives general or local anesthesia; the abdomen and vulva are disinfected and draped; the appropriate surgical incision is selected according to the size and location of the myoma; the location, size and number of uterine myoma are explored to determine the location of the uterine incision; the myoma is removed from the uterine incision, and the uterine incision and abdominal wall incision are sutured. Myoma removal usually uses a knife-cutting surface stripper with a sharp tip, but the existing stripper is usually a stripping knife, which requires the doctor to operate it by hand, and has high requirements on the doctor's technique. Moreover, after the myoma is stripped, the blood and water flowing out of the broken tissue cannot be directly drained out, nor can it be disinfected.

[0008] Therefore, it is necessary to propose a gynecological uterine fibroid stripping device to solve the above problems. Summary of the invention

[0009] Aiming at the problems that the existing myoma strippers have high requirements on the technique and cannot drain blood and disinfect, the present invention proposes a gynecological uterine myoma stripping device.

The disinfection water pump and the recovery liquid pump are connected to the connecting pipe through a disinfection liquid pipe and a recovery liquid pipe, and valves are provided on the disinfection liquid pipe and the recovery liquid pipe.

[0013] In a preferred embodiment of the present invention, the lifting module includes a lifting motor and a lifting seat connected to the output end of the lifting motor, the lifting motor is fixedly arranged on the top cover of the volume cylinder, and one end of the limit rod is inserted into the lifting seat.

[0014] Furthermore, the limiting sleeve includes a hollow cylindrical rigid outer shell and an inner sleeve, the inner wall of the rigid outer shell is provided with a buffer layer, a plurality of springs are connected between the buffer layer and the inner sleeve, and the middle part of the operating rod is fixedly inserted in the inner sleeve.

[0015] Furthermore, a plurality of limiting rubber rings are arranged at intervals on the inner wall of the outer rod, and the front end of the inner through rod is limited after passing through the plurality of limiting rubber rings in sequence.

[0016] Furthermore, the cover head is a cylindrical structure, the front end of which is an open structure, and the diameter of the cover head is 3-5 cm larger than the diameter of the outer rod.

[0017] Furthermore, one end of the sharp knife away from the inner through rod is in a vertical line with the outer wall of the inner through rod.

[0018] Implementing the embodiments of the present invention has the following beneficial effects:

[0019] The gynecological uterine fibroid stripping device of the present invention can adjust the height of the operating rod during uterine fibroid stripping through the lifting module, so that the cover head of the outer rod can be aligned with the fibroid to be stripped and cover it, thereby preventing the uterine wall beside the fibroid from being scratched by the sharp knife during stripping, and the fibroid can be completely removed;
