Problems solved by technology

The uterine dilating rod of this structure mainly has the following defects: one is: because the uterine dilating head 11 is of equal diameter, the rod must be frequently changed during the operation, for example, when the cervix will be expanded from 4.5mm to 6.5mm, then Rods need to be replaced 6 times, and if the dilatation rod is different from 4mm to 7.5mm, it is necessary to change 8 dilating rods of corresponding specifications, which will not only prolong the operation time, but also increase ...

Embodiment 1

[0024] Please combine figure 1 , at the end of the rod body 1 with a diameter of 6.5 mm and a length of 12 cm, an expansion head 2 forming an angle α of 165° with the rod body 1 is integrally extended, the expansion head 2 is a cone, The length of the expansion head 2 is 4cm, and gradually expands from the front end 21 of the expansion head 2 to the base 22 of the expansion head 2 at a rate of 0.5mm, that is, gradually expands from the diameter of the front end 21 to the base 22 The diameter is 6.5mm, that is to say, there are 6 diameter sections including 4mm, 4.5mm, 5mm, 5.5mm, 6mm and 6.5mm between the front end 21 and the base 22 . The dilating rod with such a structure actually contains 6 specifications of dilating rods that need to be replaced during one operation in traditional surgery. Helps shorten the surgical procedure.

[0025] The rod body 1 and the dilator head 2 are made of flexible medical polymer materials such as polypropylene or polyvinyl chloride. The d...

Embodiment 2

[0028] The end portion of the rod body 1 is integrally provided with an expansion head 2 forming an angle α of 168° with the rod body 1. The length of the expansion head 2 is 4 cm, and the diameter of the expansion head 2 from its front end 21 is The diameter gradually expands from 5.5mm to the diameter of the base 22 of 7.5mm, that is, from the front end 21 to the base 22, the diameter gradually expands in increments of 0.5mm, thereby forming a structure including 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, There are 5 diameter sections in total; the material of the rod body 1 and the expander head 2 is medical polymer material such as nylon or silicon rubber. The rest of the same pair

Abstract

The invention discloses a uterine-expanding rod in the medical appliance domain, which consists of rod bulk and uterine-expanding head, wherein the shape of uterine-expanding head is conoid. The invention avoids infecting effectively, which is easy to operate for doctor.

Description

technical field [0001] The invention relates to a uterine dilating rod, which is used for dilation of the cervix in the uterine cavity suction operation of obstetrics and gynecology, and belongs to medical equipment. Background technique [0002] The uterine dilator is a surgical instrument used to dilate the cervix. It has been used for a long time in uterine suction surgery in obstetrics and gynecology. So far, a set of uterine expansion sticks used in a complete operation involving women who need artificial abortion due to unwanted pregnancy are usually 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, etc., Every 0.5mm is a grade number. It can be seen that in order to complete the dilation of the uterus for the recipient, a set or set of dilation rods with specifications ranging from small to large as mentioned above is often required, so the rods must be changed frequently throughout the operation, which will not only prolong the operation time , and will increase the pain of...
