A cervical cone cutter

Abstract

The invention discloses a cervical cone cutter, which comprises a sleeve and an operating rod. The operating rod is threaded through the sleeve and matched with the sleeve. The front section of the operating rod is provided with a cone cutting mechanism, and the cone cutting mechanism includes a sliding sleeve And the linkage mechanism, the sliding sleeve is slidingly matched with the operating rod, each set of linkage mechanisms includes a first connecting rod and a second connecting rod, the front end of the first connecting rod is hinged with the front end of the operating rod, and the rear end of the first connecting rod is connected to the second connecting rod. The front ends of the connecting rods are hinged, and the rear end of the second connecting rod is hinged with the sliding sleeve; the first connecting rod is equipped with a knife holder along its length, and a double-edged knife for cutting the cervix is ​​installed on the knife holder; It is connected with an adjusting rod for controlling the sliding of the sliding sleeve. When the sliding sleeve is slid toward the front end of the operating rod through the adjusting rod, the double-edged knife on the first connecting rod is spread out to be inclined with the operating rod to form a Cone cutter for cutting. The invention can effectively conical cut the cervical tissue, and can control the cutting depth and taper.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cervical conization device. Background technique [0002] Cervical lesions, cervical cancer and other diseases are common and frequently-occurring diseases in gynecology. Severe cervical cancer will endanger the life of patients. Timely surgical biopsy and diagnosis can save many patients' lives after treatment. Cervical conization is a surgical method used in gynecology to diagnose the degree of cervical lesions and remove the lesions at the same time, that is, to cut off part of the cervical tissue in a conical shape from the inside to the outside. organization. [0003] At present, cold knife conization or coil loop electrosurgical excision (LEEP) is more commonly used in clinical practice. Due to the large scope of surgical resection of the cervix, some operators are prone to deviate from the midline of the cervical canal during the operation, resulting in uneven c...

AI Technical Summary

Problems solved by technology

[0003] At present, cold knife conization or loop electrosurgical excision (LEEP) are widely used clinically. Due to the large range of surgical resection of the cervix, some operators tend to shift the midline of the cervical canal during the operation, resulting in uneven cutting and cutting of cervical tissue. If the cervix is ​​not tapered, the cervix is ​​cut too much on one side, and the diseased tissue on the other side of the cervix cannot be effectively removed, a second operation is required; in addition, there is no clear standard for judging the depth of conization during the operation. When the depth is too wide, it may even cause uterine perforation, cervical canal perforation, damage to adjacent organs such as bladder and rectum, etc., and the incidence of postoperative complications such as postoperative wound bleeding, cervical canal adhesion and atresia, and cervical stenosis is also high.
