Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that a plurality of cervical dilation rods with different diameters and specifications need to be sequentially inserted into the cervix to dilate the cervix when the traditional cervical dilation rod is used for dilating the cervix. Cervical dilator rod and method of use can effectively reduce the risk of cervical infection

Embodiment Construction

[0033] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings. During the description, the insertion direction of the present invention into the cervix is ​​defined as "front", and the opposite direction is defined as "rear".

[0034] Such as figure 1 with Figure 9 As shown, a telescopic cervical dilation rod includes a central dilation rod 1 , a primary dilation rod 2 , a secondary dilation rod 3 and a fourth dilation rod 4 . The central expansion rod 1, primary expansion rod 2, secondary expansion rod 3 and fourth expansion rod 4 are all made of stainless steel. The central expansion rod 1 is a circular rod-shaped structure. The diameter of the central expansion rod is 4-5 mm. The front end of the central expansion rod 1 is arc-shaped. A first pull bolt 5 is provided on the side of the rear end of the central expansion rod 1 . The first pull bolt 5 includes a rod body with one end connected ...

Abstract

The invention discloses a telescopic cervical expansion rod, which comprises a central expansion rod, a primary expansion rod which is sleeved on the central expansion rod and moves relative to the central expansion rod, and a primary expansion rod which is sleeved on the primary expansion rod and is opposite to the primary expansion rod. The moving secondary expansion rod and the tertiary expansion rod sleeved on the secondary expansion rod and relatively moving with the secondary expansion rod, the central expansion rod, the primary expansion rod, the secondary expansion rod and the tertiary expansion rod are coaxial Set and the diameters increase sequentially. The invention is easy to operate, causes little pain to the patient, and greatly reduces the risk of cervical infection.

Description

technical field [0001] The invention relates to a cervical dilation technology, in particular to a telescopic cervical dilation rod and a usage method. Background technique [0002] Cervical dilation is a necessary step in gynecological abortion (currently the main means of terminating unplanned pregnancy), placement or removal of intrauterine devices, and preoperative gynecological operations that require dilation of the cervix. Cervical dilator rods are currently the main instrument used for cervical dilation. During cervical dilation, cervical dilation rods with different diameters (φ4.0mm, φ5.0 mm, φ6.0 mm, φ7.0 mm) are inserted into the cervix in order of diameter from small to large for dilation. The disadvantage of this dilation method is that the operation process is relatively cumbersome, and during the dilation process, multiple metal dilation rods with different diameters need to be inserted into the cervix one by one, and the cervix is ​​prone to adverse reactio...
