Description

Technical Field

[0001] The utility model belongs to the field of instruments for cervical electroresection, and particularly relates to a multifunctional adjustable cervical electroresection ring. Background Art

[0002] Cervical Leep is an important means for clinical diagnosis of early cervical cancer and treatment of cervical lesions. The Chinese Patent Database discloses a medical cervical internal os knife head, with patent application number: 201720736912.4, application date: 2017.06.23; its structure includes a knife head body, the knife head body includes a rotating rod with a heat-conducting rod inside, a cutting coil is provided on one side of the front end of the rotating rod, the cutting coil is in an arc shape, and a knife head handle is provided on the inner end of the cutting coil, and the knife head handle is made of insulating non-heat-conducting material; the rear end of the rotating rod is connected to a conductive rod through a threaded head, and two circuits are provided inside the conductive rod, and they are not connected to each other, and a grip pad is sleeved on one end of the rotating rod close to the threaded head. The knife head can be used to remove cervical tissue, but its disadvantage is that the length and angle of the cutting coil are fixed and cannot be adjusted, and it is difficult to adapt to the personalized needs of removing cervical tissues of different depths and widths during cervical electroresection.

[0003] The following problems currently exist during the Leep procedure: 1. The shape of the electrosurgical ring is fixed and cannot be adjusted according to the individual patient's situation; 2. Patients undergoing Leep are generally fertile and have varying degrees of pelvic floor prolapse and vaginal bulging. There is a risk of vaginal damage during the operation of the electrosurgical ring; 3. Patients with cervical lesions are prone to cervical contact bleeding. There will also be a large amount of smoke during the electrosurgical ring procedure for cervical resection. Both blood and smoke will affect the surgical field of view and thus the normal progress of the operation. Currently, assistants are used to assist in cleaning the surgical field. However, due to the patient's body position, there is a considerable probability that the sterile environment of the operation cannot be guaranteed during the assistant-assisted operation.

[0004] The utility model adjusts the angle and length of the electric cutting ring to meet the personalized needs of removing cervical tissues of different depths and widths during cervical electroresection, while avoiding damage to the vagina during the operation through an outer protective shell. At the same time, the smoke exhaust and blood suction function are integrated to enable the surgeon to perform the operation alone, saving human resources and avoiding contamination of the surgical field.
