Description

Uterus anesthesia equipment

Technical Field

The utility model relates to the field of medical equipment, concretely relates to uterus anesthesia equipment.

Background

Gynecological operations on the uterus are usually performed with the aid of anesthetic agents in order to minimize the pain of the patient during the operation.

These procedures first use a local anesthetic near the cervix, and then begin dilating the cervix using a cervical dilation apparatus. Finally, the physician will insert a tube into the cervix for subsequent surgery.

Due to the extreme sensitivity of the uterine region, in the clinic, physicians are required to inject an anesthetic in the uterus prior to any surgery. To inject the anesthetic, a syringe is first placed into the operating tube that has been inserted into the cervix. The syringe is provided with one or more openings at its distal end for delivery of anesthetic agent and is connected at its proximal end to an injection device.

However, a common problem with this procedure is that the anesthetic is expelled from the uterus after injection, which reduces the anesthetic effect in the uterine region. Since there is a space between the syringe tube and the operating tube, the anesthetic may flow out of the space after the injection is completed. Furthermore, due to the incomplete contact between the operating tube and the cervical wall, anesthetic may also flow out along the cervical wall.

Therefore, there is a need for a uterine anesthesia apparatus that reduces drug loss.

Detailed Description

To facilitate understanding of the present invention for those skilled in the art, embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a uterus anesthesia apparatus, which is characterized in that: the cervical dilator comprises an outer tube 100 and an inner tube 200 arranged in the outer tube 100, wherein the length of the inner tube 200 is greater than that of the outer tube 100, the outer tube 100 comprises a first near end 101 and a first far end 102, the diameter of the outer tube 100 is set to be 4-8 mm, and the diameter of the outer tube 100 is gradually reduced from the first near end 101 to the first far end 102, so that the cervical dilator is convenient to insert into a cervix. The inner tube 200 comprises a second proximal end 201 and a second distal end 202, the second distal end 202 of the inner tube 200 is configured to be closed and have a hemispherical shape, so as to prevent the inner tube 200 from injuring the uterine wall when extending from the inner tube 100 into the uterus, so as to better protect the patient, and a plurality of drug outlets 203 are arranged near the second distal end 202.

The first distal end 102 is provided with a cervical plug 103 adapted to a cervix, the cervical plug 103 is conical, and the cervical plug 103 is made of silica gel. The outer surface of the cervical plug 103 is provided with a plurality of annular protrusions 104, the annular protrusions 104 are screwed upwards from the bottom of the cervical plug 103 to the top of the cervical plug 103, and the purpose of the annular protrusions 104 is to make the cervical plug 103 better clamped in the cervix and prevent the medicine from leaking from the gap between the outer tube 100 and the cervix. The middle upper part of the inner tube 200 is provided with an inner tube plug 204 which is mutually attached to the inner wall of the outer tube 100, and the inner tube 200 and the inner tube plug 204 can move back and forth in the outer tube 100. The inner tube plug 204 is conical, the inner tube plug 204 is made of silica gel or other elastic materials, and the inner tube plug 204 is used for preventing the medicine from flowing out of the gap between the outer tube 100 and the inner tube 200.

The utility model discloses a method of use is, at first insert the cervix gradually with first distal end 102 of outer tube 100 until cervical stopper 103 blocks in the cervix just, then insert inner tube 200 together with interior stopple 204 in outer tube 100 until suitable position from first near-end 101, later link to each other second near-end 201 with injection device, begin to inject the anesthetic at last, extract inner tube 200 after the anesthetic absorbs.

The above-mentioned embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
