DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(4) Referring to FIG. 1 and FIG. 2 of the drawings, according to a preferred embodiment of the present invention is illustrated, a full-vagina sleeve cylindrical expansion and pneumoperitoneum integrated device, comprising:

(5) an elastic embedded ring 1 which is made of elastic material and embedded inside a pelvic outlet, wherein the elastic embedded ring 1 capable of expanding in a natural state inside a vagina to tightly adhere to a wall of the vagina, or being inflated into an annular ring which tightly adheres to the vagina wall so as to elastically expand a vagina tissue, wherein the annular ring is capable of charging and discharging independently;

(6) a sleeve 2 which is made of elastic material or a non-elastic material and is cylinder-shaped; wherein a front end ring of the sleeve 2 is connected with the elastic embedded ring 1, and a rear end ring extends out of the vagina, an operation mask 3 is fixedly provided on the rear end ring, an operation hole 6 and an observation hole 5 which are capable of being sealed are respectively provided on the operation mask 3, the operation mask 3 serves as an end surface sealing plate, in such a manner that an inflatable sealed space is formed inside the vagina and the sleeve 2., wherein the sleeve is a single-layered structure, and a diameter of the sleeve is greater than the vagina; and

(7) a fixing supporter 4 which is liftable for supporting the operation mask 3 and regulating height of the operation mask 3, so as to facilitate operation.

(8) Effects of each part of the present invention are as follows.

(9) The elastic embedded ring 1 is annular ring shaped, or annular ring shaped after being inflated, so as to prevent the sleeve from slipping to fully expand channel of the vagina. The elastic embedded ring is provided in a deep portion of the vagina. A lateral wall of the annular ring firmly adheres to a vagina wall to expand vagina tissue, so as to stretch the sleeve towards a direction out of the vagina to generate a pressure between the elastic embedded ring and an opening of a pelvis, in such a manner that the wall of the vagina is firmly adhered on the annular ring, so that an enclosed space is formed between the vagina and the sleeve. A pelvic cavity has a great space for expanding, so the annular ring can full expand in the pelvic cavity, so as to guarantee a spacious enough space in a channel of the vagina for operation. The annular ring is embedded inside the pelvic outlet, so as to ensure that the annular is not capable of slipping from the vagina.

(10) The sleeve is for expanding the vagina. The sleeve comprises an inner part inside the vagina and an outer part outside the vagina. The inner part of the sleeve does not occupy too much space inside the vagina. A diameter of the sleeve is greater than a diameter of the vagina. Due to the loose of the sleeve and the elastic and shrinking effects of the wall of the vagina, the sleeve after gas filling expansion is tightly pressed on the wall of the vagina, so that an external surface of the sleeve is more tightly adhered to the space of the vagina. Furthermore, after the vagina is fully expanded, a more spacious space is formed inside the sleeve, so as to facilitate surgical operation through the vagina. The outer part of the sleeve effectively stretches the operation space which is sealed towards extracorporal space of the patient, without being limited inside the narrow space of the patient. In addition, an external diameter of the sleeve can be further enlarged, so that the operation mask 3 has an adequate position for providing the operation holes 6 and the observation holes 5 and etc, so as to satisfy the operation condition fully. The sleeve can be designed into various models with different length and thickness according to the requirements of operations and conditions of the vagina.

(11) The operation mask is used for entry and exit of the operation instrument. In FIG. 2, the operation instrument is a handling tong 11. Due to extension effect of the sleeve, the operation mask 3 is provided outside the vagina. An area of the operation mask can be enlarged appropriately according to the requirements of the laparoscopic operation. A plurality of operation holes 5 and observation holes 6 with various sizes is provided on the operation mask 3. A valve is fixedly provided in the operation holes 5, or the observation holes 6, or the valve is additionally installed; or otherwise, a puncture outfit comprising the valve, which is utilized in a conventional laparoscope, is provided inside the operation holes 5 or the observation holes 6. Idle holes in the operation are filled and sealed by an air lock. A sealed operation mask made of elastic material can be adopted, so as to assured that the operation mask can be punctured by outfit utilized in the conventional art Retraction effect of the elastic material is depended upon for sealing space and regulating along direction of the surgical operation. After being inflated by a gas tube 9 through the observation holes 5, the operation holes 6 or an inflation hole provided on the operation mask or the sleeve, a pressure is formed in a sealed cavity of the vagina, so as to full expand the vagina in a cylindrical shape and push up uterus 7. When the cavity 8 of the vagina (a front part or a rear part of the cavity) is cut, a pressure can be generated in the vagina and the abdominopelvic cavity which are sealed to form a fully expanded vagina channel and expose surgical field of pneumoperitoneum. Laparoscopic operation instrument with a long handle takes the observation holes as a pivot, so as to maintain the surgical operation in a steady and precise state. A laparoscope 10 supported in the observation hole is for observing operation process mentioned above.

(12) A bottom of the fixing supporter is provided on the ground, an up portion of the fixing frame 4 is for fixing the operation mask or bearing a steady operation mask for a platform. If the operation mask is fixed and controlled by a mechanical arm aside an operation table, the fixing frame 4 is not required.

(13) By utilizing the device of the present invention, an incision is not cut on a dominal wall, so as to avoid leaving scars on the dominal wall. As an auxiliary surgical instrument, the full-vagina sleeve cylindrical expansion and pneumoperitoneum integrated device combines advantages of the conventional gynecologic laparoscopic operations and the conventional vagina operations, enhances advantages and avoids disadvantages of the two kinds of operations, so as to achieve a more minimal invasion in treating gynecopathy.
