Multi-channel hysteroscopic surgery operating system

Abstract

The present invention discloses a multi-channel hysteroscopic surgery operating system, the main body of which is composed of a cervical cap, a long sheath base, and a control push rod. The hemispherical surface of the cervical cap is connected to the long sheath base, and the front-end annular sealing ring is connected to the control push rod. The cervical cap is a hollow hemispherical structure, provided with a hemispherical surface, an annular sealing ring, and an elastic washer. The control push rod is composed of a pressing plate handle and an annular ring. The annular ring is a rigid structure, composed of an elastic limit rotating shaft and an annular ring. The elastic limit rotating shaft is provided with a return spring, a free rotating shaft, and a limit cushion. The pressing plate handle is made of solid material, and a pin shaft locking arc is provided at its connection. The horizontal baffle limit step on the plane of the pressing plate handle can control the plane of the pressing plate handle to be perpendicular to the plane of the annular ring. In the present invention, a closed high-pressure circulating water space is formed jointly by the uterine cavity, the cervical canal, and the vaginal fornix, enabling multiple channels and multiple instruments to enter the high-pressure circulating water space and the uterine cavity, effectively preventing mutual interference and facilitating uterine cavity surgery.

Description

Technical Field

[0001] The present invention relates to an auxiliary device for hysteroscopic surgery. Background Art

[0002] In order to ensure high-pressure water injection and drainage during hysteroscopic surgery, and to enable visualization through the hysteroscope and simultaneous operation of surgical instruments, currently in hysteroscopic surgery, a rigid cervical dilator is inserted into the narrow cervical canal through the vagina, and mechanical means are used to forcibly dilate the cervical canal. Then, a cervical protection sheath is inserted, high-pressure water is injected into the uterine cavity to expand it, and a cylindrical hysteroscope is inserted through the rigid cervical protection sheath for observation. Due to the limitation of the narrow cervical canal, especially the fact that the rigid cervical protection sheath occupies the space of the cervical canal, the inner diameter of the rigid cervical protection sheath is further restricted. Under the observation of the inserted hysteroscope, currently only a surgical instrument with a long handle can pass through the rigid cervical protection sheath into the uterine cavity for surgical operation. Obviously, this single-channel hysteroscopic surgery is like a one-handed operation. Due to the lack of assistance, it is often difficult to operate. Moreover, both the hysteroscopic observation and the operation of the surgical instrument must follow the fixed straight path of the rigid cervical protection sheath. The long-handled instrument cannot turn independently and freely, making the operation inconvenient. Summary of the Invention

[0003] The present invention aims to avoid the deficiencies of the above-mentioned prior art. By abandoning the rigid cervical protection sheath used in traditional hysteroscopic surgery, it gets rid of the trouble of the rigid cervical protection sheath occupying space and restricting the independent and free turning of the cylindrical laparoscope and the long-handled instrument. It gives full play to the space of the cervical canal and the elastic activity performance of the cervical canal tissue, and utilizes the space and airtight effect of the vaginal apical fornix. A high-pressure circulating water space is formed jointly by the uterine cavity, the cervical canal, and the vaginal fornix, enabling multiple channels and multiple instruments to enter the high-pressure circulating water space of the uterine cavity, and enabling multiple instruments to cooperate with each other in surgical operation after entering the uterine cavity, and being able to turn independently and freely without interfering with each other.

[0015] 3. The circulating water in a high-pressure state in the vaginal fornix, cervical canal and uterine cavity has the effect of actively dilating the cervical canal, which is beneficial for surgical instruments to enter the uterine cavity and avoids mechanical dilation of the cervical canal.

[0023] Assemble the annular ring (322) and the elastic limit rotating shaft (321) to form the annular ring (32). First, snap the limit cushion (3213) into the limit card slot (32121) at any end of the free rotating shaft (3212), put the return spring (3211) on the shaft, insert the free rotating shaft (3212) into the shaft hole at the right end of the annular ring (322), and use a pressing tool to make the other end of the free rotating shaft (3212) expose from the left side of the annular ring (322) to the limit card slot (32121) and snap in another limit cushion (3213). The free rotating shaft (3212) is controlled at the middle position of the shaft hole of the annular ring (322) under the action of the limit card slot (32121) and the return spring (3211).

[0024] Grip the pressing plate handle (31) and hook the slot (312) at its lower end onto the free rotation shaft (3212) of the annular ring (32). The annular ring (32) can rotate along the free rotation shaft (3212). When the annular ring (32) rotates to a perpendicular angle with the pressing plate handle (31), the horizontal baffle limiting step (314) on the plane of the pressing plate handle (31) can control the plane of the pressing plate handle (31) to be perpendicular to the plane (3222) of the annular ring (322).

[0025] Insert the annular sealing ring (12) into the annular sealing ring slot (3221) of the annular ring (32). Grip the control push rod (3) and rotate it along the elastic limiting rotation shaft (321) to make the plane (3222) of the annular ring (322) parallel to the plane of the pressing plate handle (31). Insert the annular sealing ring (12) into the vagina, and at the same time, partially insert the hemispherical surface (15) and the long sheath base (2) into the vagina. Stretch the base (22) of the long sheath base (2) outside the body, so as to stretch the hemispherical surface (15) of the cervical cap (1), and then stretch the annular ring (322). The annular ring (322) rotates along the elastic limiting rotation shaft (321), and the horizontal baffle limiting step (314) on the plane of the pressing plate handle (31) restricts the continuous rotation of the annular ring (322), controlling the plane of the pressing plate handle (31) to be perpendicular to the plane (3222) of the annular ring (322). The elastic washer (11) on the outer periphery of the annular ring (32) tightly presses the vaginal wall annularly, and inflate the elastic washer inflatable tube or expand the elastic washer (11) with liquid to make it tightly seal and press the vaginal wall.

[0026] Inject liquid through the three-way pipe (222) of the base (22). The liquid passes through the sheath tube (21), is injected into the vaginal fornix (42), and enters the uterine cavity (44) through the cervical canal (43). Under high pressure, the liquid expands to enlarge the cervical os (41) and the cervical canal (43), and expand the uterine cavity (44).

[0027] Insert the hysteroscope (5) through the sheath base (22). The hysteroscope enters the uterine cavity (44) through the sheath tube (21), the vaginal fornix (42), and the cervical canal (43) to observe the lesions (45) in the uterine cavity. Enter the surgical instruments (6) through other sheath bases (22) respectively to reach the uterine cavity (44) and cooperate to remove the lesions (45) in the uterine cavity.

[0028] Open the three-way pipe (222) of the base to drain the liquid in the uterine cavity (44), the cervical canal (43), and the vaginal fornix (42). Pull the control push rod (3) outwards and rotate it along the elastic limiting rotation shaft (321) to make the plane (3222) of the annular ring (322) parallel to the plane of the pressing plate handle (31), and then side out the annular sealing ring (12) from the vagina to complete the operation.

[0029] The above embodiments only describe the preferred embodiments of the present invention and do not limit the scope of the present invention. Any equivalent transformation or modification made to the present invention without departing from the spirit and essence of the design of the present invention shall be covered within the protection scope of the present invention.
