Cervix conization instrument used in gynecology department

Abstract

The invention discloses a gynecological cervical cone cutter, which comprises a knife chamber, a central tube, a rotary cutter shaft and a driving mechanism. Outside the central tube; the front end of the knife compartment is provided with a negative pressure suction cup, an adsorption cavity is formed between the knife compartment and the negative pressure suction cup, and the rear end of the knife compartment is equipped with a charge and deflation control device; A balloon is installed and connected, and the rear end of the central tube is connected with an inflation and deflation control device for controlling the expansion and contraction of the balloon; the front end of the rotary cutter shaft is fixed with a rotary cutter, and the negative pressure suction cup is provided with a through Equipped with the knife groove of the rotary cutter; the drive mechanism is connected to the shaft of the rotary cutter to drive the rotary cutter to rotate to achieve conical cutting. It has the following advantages: simple structure, convenient operation, and less human resources required.

Description

technical field [0001] The invention relates to a medical operation appliance, in particular to a gynecological cervical conization appliance. Background technique [0002] Cervical intraepithelial neoplasia (CIN) is a group of cervical lesions closely related to invasive cervical cancer. High-grade CIN is regarded as precancerous lesions. Timely treatment of high-grade lesions is an effective way to prevent cervical cancer. Measures, cervical conization is usually used for high-grade CIN. Cervical conization is an operation performed in obstetrics and gynecology to remove the cervix, that is, to cut off a part of the cervical tissue in a conical shape from the outside to the inside. On the one hand, it is for pathological examination and diagnosis of cervical lesions; on the other hand, it is also a treatment method for excision of lesions. Cold-knife conization is a commonly used cervical conization at present. It uses a common scalpel, such as 201410747419.3, 2011200229...

AI Technical Summary

Problems solved by technology

Cold-knife conization is a commonly used cervical conization at present. Common scalpels are used, such as 201410747419.3, 201120022920.5, and 201520319058.2 published in the Chinese patent database. Smooth, difficult to control the amount of conization, requires a lot of human resources, largely depends on the operator's experience, difficult to suture hemostasis, postoperative wound bleeding repeatedly, thus bringing unnecessary pain to the patient
