Description

Hysteroscope and hysteroscope body sheath

Technical Field

The utility model relates to a medical appliance, in particular to a hysteroscope which can guide a therapeutic appliance.

Background

In the process of hysteroscopy, even if polyps, embryo residues or intrauterine adhesions are found in the uterine cavity, the scissors, the forceps and other therapeutic instruments alone cannot easily pass through the blind areas such as the vagina, the cervical canal and the like, so that higher technical requirements are provided for doctors to further develop hysteroscopy. In addition, the front end of the scissors is sharp and sharp, and the vagina and the mucosa of the cervical canal are easily scratched, so that a plurality of limiting factors are faced to widely carry out the hysteroscopy operation in outpatient service.

The cold knife system wraps the therapeutic apparatus and the uterine cavity examination mirror together, and the whole diameter of the apparatus is enlarged, so that the uterus needs to be expanded to 8-10mm during treatment. Chinese patent CN201379632Y discloses a uterine cavity surgical instrument, which is a system formed by a uterine cavity forceps and a hysteroscope in a manner of synchronous movement and independent operation, so as to ensure that the entry and operation of the instruments are under the monitoring of the hysteroscope, but the hysteroscope needs to be withdrawn together when the instruments are replaced, which still requires a long time in the whole treatment process, and the operation range of the instruments is limited, which causes frequent replacement of the visual field of the hysteroscope, reduces the continuity of the operation, and affects the treatment effect.

Chinese patents CN212438557U and CN212346681U disclose combined and single type hysteroscope instrument operation propeller respectively. The two propellers need to be customized according to the outer diameter of the hysteroscope body, wherein the single propeller is embedded with the sheath of the hysteroscope body through the clamping groove, the size of the hysteroscope body cannot be increased too much, but the propeller is not easy to slide on the hysteroscope body because the clamping groove is embedded too tightly, and the propeller is easy to fall off from the hysteroscope body because the clamping groove is loosened; the combined propeller introduces the convex strip as a track for the sheath to slide, but the processing and the assembly of the convex strip and the track are high in requirement, inconvenient to use and obviously increase the size of the endoscope body. In addition, the combined pusher and the single pusher are not compatible with each other on the endoscope body, and one of the combined pusher and the single pusher must be removed from the endoscope body and then installed on the other, so that the functional advantages of the different types of pushers cannot be fully utilized in the guidance of the therapeutic device.

The application method of the uterine cavity examination mirror is as follows:

1) When polyps, intrauterine adhesion, submucosal myomas and other conditions are found in the uterine cavity in the process of hysteroscopy, if treatment is needed, the hysteroscopy scope is not needed to be moved out of the uterine cavity, for instruments with blunt front ends such as forceps and the like to be fed into the uterine cavity, the front ends of the instruments can be directly placed into the sliding initial position 1-2 of the slideway 1-1 and moved to the sliding final position 1-3 along the slideway 1-1 (the base of the sliding head 1-4 is clamped by utilizing the part of the foremost end of the hysteroscope body sheath 1, which does not form the slideway 1-1, so that the sliding head 1-4 can not continuously slide forwards); for instruments with sharp front ends such as scissors and the like to be fed into a uterine cavity, the front ends of the instruments are placed into the sliding heads 1-4 to push the instruments, the instruments move to the sliding end positions 1-3 of the slideways 1-1 along with the sliding heads 1-4 (the sliding heads 1-4 cannot slide forwards continuously after reaching the positions), the instruments are withdrawn from the sliding heads 1-4, then the direction of the uterine cavity examination mirror is rotated, the reels 1-8 are rotated, and the sliding heads 1-4 are retracted to the rear ends of the slideways 1-1 (namely the sliding starting positions 1-2).

2) The hysteroscope is retracted until the front end of the instrument is seen on the display connected to the hysteroscope endoscope 2, and then the treatment operation is performed. When the instrument for treatment operation needs to be replaced, the instrument used in the current operation is withdrawn (if the instrument needs to be replaced in the treatment, the instrument can be directly taken out), and then the operation is repeatedly carried out according to the mode of delivering the instrument, so that the treatment operation can be continued.

The uterine cavity examination mirror has the characteristics that:

the therapeutic apparatus can be directly or along with the sliding head, pass through the dead zones of the vagina and the cervical canal and be smoothly sent into the uterus, so that the interval time between treatment operations can be shortened, and because a device integrating the hysteroscope and the apparatus into a whole is not needed, only about 6mm of the uterus opening needs to be expanded, some conventional treatments basically do not need to expand the uterus, the pain of a patient in the operation can be relieved, and the hospitalization is avoided. Meanwhile, the operation of the instrument is less limited, the instrument can be continuously and flexibly operated under the view field of the hysteroscope provided by the display, in addition, the objective requirements on durability and easy obtaining of the instrument can be met, the therapeutic instrument with simpler structure and thicker size can be selected and used, and the cost of the instrument is reduced (the instrument does not need complicated and fine structural design, so that the instrument is easy to operate and not easy to damage).

The functions of the single-body propeller and the combined propeller (such as CN212438557U and CN 212346681U) are combined together, and the mechanical guidance is directly carried out on the shell (sheath) of the hysteroscope body, so that the propeller does not need to be manufactured in a customized manner, and the size adaptation is not needed any more.
