Description

Multichannel hysteroscope operation access system

Technical Field

The invention relates to the field of medical instruments, in particular to a multi-channel hysteroscope operation access system.

Background

At present, a hysteroscope surgical instrument directly enters a uterine cavity through a cervical canal through a vagina and only has a single operation channel, the caliber of a hysteroscope sleeve is various, and is usually 5-10MM, so that the hysteroscope examination and operation can be realized, but the conventional operation can only realize the operations of cutting, electrocoagulation, suction and the like, but if complex operations are required to be carried out in the uterine cavity, such as the suturing in the uterine cavity, surgical instruments such as a hysteroscope, a needle holder and the like need to be placed, the operation can be finished only by entering the uterine cavity through independent multiple channels, the traditional single channel can not be finished, and the traditional hard multi-channel hysteroscope is a multi-channel completely integrated in a hysteroscope, still is the same channel in the actual sense, and can not finish the complex uterine cavity operations such as suturing and the like; in addition, because the cervical orifice needs to be fully expanded in complex uterine cavity operation, the hysteroscope and the cervical canal cannot be perfectly attached, and the uterine expansion liquid flows out through the separately expanded cervix, the uterine cavity expansion pressure is low, the operation is difficult to realize, even if the complex hysteroscope operation is not needed, the situation that the uterine expansion liquid flows out to reach the proper uterine expansion pressure due to the fact that the cervical canal is loosened, the cervix is clamped by the cervical clamp frequently at the moment, and the cervical injury is easily caused is also frequently seen clinically. Therefore, the invention researches and manufactures a multi-channel hysteroscope operation access system to solve the problems.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention easier to clearly understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

As shown in the attached drawing, a multichannel hysteroscope is operation access system down, including main entrance 1, main entrance 1 is cylindrical, main entrance 1 is hollow structure, main entrance 1's one end is equipped with opening 2, the other end is equipped with hemispherical blind end 3, be equipped with a plurality of supplementary logical chambeies 4 on the blind end 3, supplementary logical chamber 4 is tubule type passageway, supplementary one end and the main entrance 1 intercommunication that leads to chamber 4, the other end are equipped with expansion mouth 5, expansion mouth 5 is the loudspeaker form, supplementary logical chamber 4 is last still to be equipped with ooff valve 6.

The main channel 1 is made of elastic soft plastic or silica gel material with certain supporting force.

The number of the auxiliary through cavities 4 is three, and the auxiliary through cavities are evenly distributed on the closed end 3.

The auxiliary through cavity 4 is made of plastic or silica gel material.

The switch valve 6 is a clamp for controlling whether the auxiliary through cavity 4 is communicated or not, and the switch valve 6 is made of hard plastics.

The inner diameter of the channel inlet is larger than the inner diameter of the auxiliary through cavity 4.

The main channel 1, the closed end 3 and the auxiliary through cavity 4 are integrally formed.

When in use, the main channel 1 enters the uterine cavity through the vagina and the cervical canal, and then the hysteroscope and the surgical instrument are simultaneously placed in the auxiliary through cavity 4, thus realizing complex operations such as suturing in the uterine cavity.

The invention discloses a multichannel hysteroscope operation access system which is applicable to uterine cavity suture situations and comprises the following components:

1. the problem of falling off is solved by a left norgestrel intrauterine sustained release system uterine cavity suture fixation method, a patient with conventional uterine bleeding, adenomyosis and the like needs to place the left norgestrel intrauterine sustained release system, but the patient is forced to select other treatment schemes with larger wound and higher cost due to larger uterine cavity and frequent falling off, the problem of falling off of the left norgestrel intrauterine sustained release system can be solved by uterine cavity suture, the wound is greatly reduced, and the treatment cost is saved;

2. after the hysteroscopic excision of larger II or III type submucosal myoma, the conventional hemostasis is electrocoagulation or saccule compression, the effect is poor, the cost is high, and the uterine cavity suture hemostasis and uterine cavity adhesion prevention effects are obvious;

3. diverticulum suture under a hysteroscope of a diverticulum patient with a uterine incision and lower uterine segment molding operation, wherein the traditional operation is a laparoscope or an open abdomen operation, the wound is large, the cost is high, and the cost can be saved by adopting the invention to perform the operation;
