Cock liquid injection type cervical dilator

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a cock liquid injection type cervical dilator.

Background

In gynecological clinical examination, diagnosis and treatment, various endoscopes, instruments and medicines enter the uterine cavity, and a channel is required to be established by expanding the cervical canal. The expansion methods which are more commonly used clinically at present mainly comprise: the medicine expansion, the metal rod of pure physical and mechanical expansion, the expansion saccule, the silica gel rod, the seaweed rod, the sponge rod and the like which absorb body fluid self-expansion are also available.

However, in the above, adverse reactions and contraindications exist in drug expansion, and administration is required to be carried out 2-3 hours in advance to fully relax and soften cervical canal; the metal rod for dilating the cervical canal by mechanical compression is easy to cause cervical collateral damage and cross infection; the balloon-expanded patient has poor body feeling, can cause cervical mucosa injury due to improper operation, and is mostly used for expansion of the later stage of pregnancy; by means of the expansion methods such as a silica gel rod, a seaweed rod, a sponge rod, a polymer gel rod and the like which absorb the body fluid of the uterine cavity, the expansion is slow due to individual differences, the uterine cavity needs to be placed in cervical canal 1-3 hours in advance, and some products are placed in the evening for the next day of operation.

Although the above-mentioned expansion methods have respective advantages, they have a common point that the expansion time is slow, so that the operation efficiency and resources are not fully utilized and improved, and the burden of the patient is increased. In order to solve the above problems, a cock-type liquid-injection cervical dilator is proposed.
