Detailed Description

The following will describe in further detail a gateway device for transvaginal retrieval of surgical resection in accordance with the present invention with reference to the accompanying drawings.

The channel device for taking out surgical excision matters through vagina consists of an outer sleeve 1, an emulsion sleeve 3, an inner sleeve 2, a light source interface 4, a lead 5 and a luminous body 6, wherein the outer sleeve 1 is a stainless steel mesh capable of being expanded uniformly and is cylindrical as a whole, a ring for grasping is welded at the tail of the outer sleeve, the head of the outer sleeve is of a petal-shaped structure, and uniformly distributed petal-shaped blades are folded in under a normal state to enable the head of the tube to form a vertebral body. The periphery of the front end of each of the petal-shaped blades is provided with the same inward flange which is gradually and smoothly bent, the flange structure can ensure that the centrum keeps stable shape under the peripheral stress state in the insertion process, the smooth flange is convenient to insert and does not stab the skin, and the petal-shaped blades of the outer sleeve 1 are unfolded and form an inverted cone after the inner sleeve 2 is completely pushed. The latex sleeve 3 is an elastic rubber sleeve with a certain thickness and a sealed front end, is sleeved outside the outer sleeve 1 and covers the tube body, the vertebral body and the petal-shaped blades, and the latex sleeve 3 can be expanded or contracted along with the structure of the vertebral body to protect the vagina from being damaged. The inner sleeve 2 is made of a metal tube with a certain thickness, and the strength of the inner sleeve can ensure that the inner sleeve can be completely inserted and expand the petal-shaped structure of the head of the outer sleeve 1 when in operation and use, so that a stable circular channel with equal diameter is formed. The light source is connected through the light source interface 4, and the luminous body 6 connected with the lead 5 forms an operation lighting source only irradiating forwards at the front end in the channel. The data acquisition sensor 7 acquires pressure intensity and other data, and outputs digital and sound signals to the data processing output unit 9 through the transmission lead 8 to detect whether the degree of expanding the vagina exceeds the tolerance limit of a human body.

The utility model discloses when concrete implementation, hold the outer tube that holds the package and have the emulsion cover, the closed lamella column structure that is the taper under together with initial condition inserts the vagina, pushes the pressurization gasbag with pressure sensor, and inflation pressurization expands the vagina, and the sensor gathers expansion pressure and exports digit and sound signal. The inner sleeve is completely pushed into the outer sleeve to enable the petal-shaped structure to be completely opened to shield the bladder and the rectum, so that the protection and support effects are achieved, and the tumor can conveniently enter the channel. The balloon is withdrawn and the light source is turned on to provide surgical operation illumination that shines forward inside the tunnel. When the operation specimen is taken out from the pelvic cavity, the operation specimen is firstly arranged in the fetching bag, the fetching bag is tightened and sealed, the operation specimen is pulled to the passage device, the fetching bag is opened and sealed in the passage, the operation instrument is stretched into the passage device to break the tumor into small blocks, and the small blocks are taken out from the passage device; the inner sleeve is pulled out of the outer sleeve, and the opened petaloid head of the outer sleeve is contracted and restored to be conical. After the operation is finished, the outer sleeve and the latex sleeve are pulled out of the human body from the vagina together, and finally the taking-out operation is finished.

The side wall of the pressurizing air bag is provided with an ultra-thin resistance type pressure sensor which can measure the pressure value born by the vaginal wall of a patient. The control device expands to the upper limit of the safe pressure value, so that the vagina expands to the maximum degree under the condition of not being damaged. The operation visual field is relatively enlarged, the specimen is more convenient to take out, thereby reducing the operation time and reducing the anesthesia risk and the infection risk in the operation. Because of the cylindrical structure, the device covers the surface of the total vaginal wall, so that a doctor can perform an operation in a relatively closed environment, and the probability of accidentally damaging the vaginal wall during the operation is reduced. The petal-shaped structure at the head end of the outer sleeve can be completely opened to shield the bladder and rectum, so as to play a role in protection and support and facilitate the removal of the tumor through the channel; meanwhile, the tumor tissue is prevented from contacting with the vaginal broken end incision, and the occurrence of tumor iatrogenic implantation metastasis is prevented. The channel device can be supported by self, so that the labor of doctors with low efficiency is reduced, and more doctors can be put into high-efficiency treatment and rescue of people. The product is provided with a cold light source for illumination, and irradiates the side of the deep vaginal pelvic cavity, thereby solving the problem of unclear operation of the vaginal operation. The head end petal-shaped structure is manufactured by using a 3D printing technology, the main material of the outer sleeve and the inner sleeve is 316L stainless steel which is the most advanced medical stainless steel material at present, and compared with 304 stainless steel adopted by a traditional vagina draw hook, the head end petal-shaped structure has higher hardness, can support the vagina wall, has thinner pipe wall and saves more space.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
