Loop electrosurgical excision cryoscalpel

Abstract

The invention discloses a loop electrosurgical excision cryoscalpel, and belongs to the technical field of medical instruments. The cryoscalpel comprises a hollow shell, a blade and a controller, thecontroller is fixedly connected to the top end of the shell, the shell comprises an upper cylindrical end and a lower conical end, a conical guide block is arranged in the conical end, and a blade accommodating groove is formed in the center of the guide block; an annular groove is formed in the guide block, a coil pipe is arranged in the annular groove, and an inlet in the top end of the coil pipe communicates with a communicating pipe; and the blade is positioned in the blade accommodating groove, the top end of the blade is detachably connected with a supporting rod extending out of the accommodating groove, a telescopic device is fixedly connected in the shell, the telescopic end of the telescopic device is fixedly connected to the top end of the supporting rod, the shell is sleeved with a limiting device, and the diameter of an inner ring of the limiting device is larger than the diameter of a circle of an outer ring of the shell. The blade is evenly cooled, the extension length of the blade is electrically controlled, and the cryoscalpel is convenient for a user to use.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, relates to an electronic cervical circumcision cold knife. Background technique [0002] Cervical circumcision 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. At present, cold-knife circumcision or LEEP is widely used in clinical practice. Due to the large scope of surgical resection of the cervix, the light cannot be illuminated from the inside out, resulting in the inability to judge the situation inside the cervical canal during surgery.

AI Technical Summary

Problems solved by technology

At present, cold knife circumcision or loop electrosurgical excision (LEEP) is widely used clinically. Due to the large range of surgical resection of the cervix, the light cannot illuminate from the inside out, making it impossible to judge the situation inside the cervical canal during surgery.

At the same time, the surgical operation space is small and the surgical field of view is not well exposed. During the operation, the surgeon can only roughly judge the direction and scope of the circumcision. Therefore, some surgeons tend to shift the midline of the cervical canal during the operation and cause cutting Inhomogeneous, causing the cut cervical tissue not to form a cone, too much cutting on one side of the cervix, and the lesion tissue on the other side of the cervix cannot be effectively removed, requiring a second operation, etc.

In addition, there is no clear standard for judging the depth of circumcision during the operation. When the cervical tissue is cut too deep and too wide, it may even cause uterine perforation, cervical canal perforation, bladder, rectum and other adjacent organs. The incidence of postoperative complications such as cervical canal adhesion atresia and cervical stenosis is also high
