Abstract
A gradual advancing expansion device of uterus cavity. The utility model is in the shape of stick with an expansion head at the front section and a handle at the rear section. It is characterized in that: the expansion head comprises at least two sections, usually three or four sections; the diameter of each section increases gradually from the smallest to the biggest one; slope transition is made in between two nearby sections. The advantage of this utility model is that one expansion device can realize the functions of several expansion devices. During the uterus expansion operation, this sort of expansion device can enter gradually, thus avoiding or reducing the change of more expansion devices, enhancing the operating efficiency and alleviating the pain of patient. The handle at the rear part of the expansion device can be made in hollow design, which would not only enhance the elasticity of the handle, improve the comfortable feel for the hand, but also reduce the consumption of materials for fabrication.
Description
[technical field]
This utility model is relevant with the gynecological medical apparatus and instruments, specifically, is a kind of uterine cavity expander, is used for expanding the palace in artificial abortion or other intrauterine surgicals in advance.
[background technology]
Present uterine cavity expander is a rod shape, and front end is an extension header, and the rear end is a handle, and an expander is a kind of specification, carries out one extension.Finish an expansion palace operation and want the ascending expander that uses plurality of specifications of changing successively, repeatedly enter the enforcement expansion and just can finish operation, very inconvenience and loaded down with trivial details has also increased misery for patient.
[summary of the invention]
The utility model proposes a kind of chamber expander of being put in prison that pursues, on an expander, make up plurality of specifications, once enter, go forward one by one successively to implement to expand and just can finish operation, improve operation efficient, minimizing patient misery.
The technical solution of the utility model is: a kind of chamber expander of being put in prison that pursues, be a rod shape, and front end is an extension header, the rear end is a handle, it is characterized in that extension header is divided into plural sections, the diameter of each sections by forward direction after, ascendingly increase progressively successively, two adjacent sections have domatic excessively.
The utility model has the advantages that an expander can play the purposes of many expanders.When implementing to expand the palace operation, once enter, go forward one by one successively, can remove or reduce the operation of changing expander from, therefore, improved operation efficient, reduce patient's misery simultaneously.
[description of drawings]
Fig. 1 is a kind of disposable structural representation by the chamber expander of being put in prison of this utility model embodiment.
Fig. 2 is the enlarged drawing of extension header part among Fig. 1.
[specific embodiment]
As shown in drawings, a kind of chamber expander of being put in prison that pursues is a rod shape, and front end is an extension header 1, and the rear end is a handle 2.The same with general expander, extension header and handle have the knuckle of 15 degree.Different with general expander, extension header is divided into plural sections 11, commonly used is divided into three or four sections.The diameter of each sections 11 by forward direction after, ascendingly increase progressively successively, it is domatic 12 excessive that two adjacent sections 11 have.The diameter difference of two adjacent sections is 0.5 to 1 millimeter.The length of each sections is 5 to 15 millimeters.The handle 2 of rear end can be designed to hollow form 21, both can increase handle elasticity, improve the comfort of hands, can reduce the consumption of making material again.
