Description

Improved cervical clamp closer

Technical Field

The utility model belongs to the technical field of medical instrument technique and specifically relates to a cervical clamp closer of improvement.

Background

Laparoscopic surgery is a newly developed minimally invasive method and is a necessary trend for the development of future surgical methods. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities. Hysteroscopy is a mature technique for treating uterine cavity diseases. With the increase of patients with uterine cavity diseases, patients who receive hysteroscopic surgery tend to rise year by year. Poor uterus expansion effect is one of the difficulties of hysteroscopy, which causes that the focus can not be completely exposed during the operation, the non-focus area is easy to be damaged, and the serious uterine cavity can be perforated, thereby increasing the operation complications.

According to the manner of hysteroscopic surgery, cervical clamps and tissue clamps are currently used clinically. However, the instruments are not attached to the shape of the cervix, and are easy to damage cervical tissues, liquid in the uterine cavity is easy to overflow from the cervical orifice, the pressure in the uterine cavity cannot achieve a satisfactory uterine expansion effect, the operation time can be greatly prolonged, and the incidence rate of uterine perforation is improved.

The Chinese patent application: CN206102719U discloses a built-in cervical closer, which is characterized in that: the cervical forceps comprise an internal piece and a placing and taking piece, wherein the internal piece is used for clamping a cervix and can stay at a clamping part, the placing and taking piece is used for taking out and placing the internal piece, an occlusion part used for clamping the cervix is arranged at one end, far away from the placing and taking piece, of the internal piece, one end of the internal piece is selectively and detachably connected with one end of the placing and taking piece, namely the internal piece comprises a first rod and a second rod, the placing and taking piece comprises a third rod and a fourth rod, the middle part of the first rod is hinged with the middle part of the second rod, and the middle part of the third rod is hinged with the middle part of the fourth rod. The device can be simply, the bleed problem of parts such as quick processing cervix uteri, cervical canal and palace chamber, but the detachable of head is put and is got the piece and when using, can not play firm effect to also be conveniently taken out when taking out, be not favorable to maintaining good uterus expansion effect.

Therefore, in view of the above, there is a need for a novel improved cervical forceps holder closer which has a simple structure and is convenient to operate, can conform to the shape and the width of the cervix, effectively maintains the pressure in the uterine cavity, achieves a satisfactory uterine expansion effect, and reduces the bleeding in the uterine cavity.

Disclosure of Invention
