Embodiment 1

[0024] like Figure 1-Figure 3 As shown, a porous endoscopic operation device through the natural cavity includes a sleeve 1. The sleeve 1 is a transparent plastic tube with a double wall structure. The diameter of the sleeve 1 is designed according to the size of different cavities, which is convenient. Observe the physical condition and the position of the instrument in the sleeve 1 during the operation. There is a piston in the sleeve 1. The diameter of the piston is equal to the inner diameter of the sleeve 1. The length of the piston is greater than the length of the sleeve 1. The front end of the piston is an arc When it is necessary to perform endoscopic surgery through the natural orifice, insert the piston into the sleeve 1, push the sleeve 1 into the vagina, anus or abdominal cavity with the piston in hand, put the sleeve 1 in and pull out the piston. out.

[0025] A first airbag 2 is fixed on the outer wall of the sleeve 1, the first airbag 2 is an annular airbag, ...

Abstract

The invention provides a porous natural orifice passing endoscope operating device which comprises a sleeve, a piston is arranged in the sleeve, a first air bag is fixed to the outer wall of the sleeve, a top cover is fixed to the upper end of the sleeve, a pressure stabilizing pipe, an exhaust pipe and an operating hole are arranged on the top cover, and an air inlet pipe is arranged on the sleeve. According to the technical scheme, the sleeve is arranged, the piston is arranged in the sleeve and helps the sleeve to smoothly enter cavities such as the vagina and the anus, tissue around the cavities is supported through the first air bag, and the endoscopic surgery of the cavities passing through the vagina and the anus is achieved; the sealing device is arranged to prevent excessive fluctuation of pressure in the cavity when an instrument enters the operation hole so that the air tightness of the device is ensured; and by arranging the air inlet pipe, the exhaust pipe, the pressure stabilizing pipe, the first valve, the second valve, the third valve and the second air bag, when pressure in the cavity fluctuates and smoke is generated by cutting, adjustment and recovery can be conducted in time, and the situation that the pressure in the cavity is stable and the visual field is clear can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of endoscopic manipulation devices through a porous natural orifice, in particular to an endoscopic manipulation device through a porous natural orifice. Background technique [0002] Natural orifice transluminalendoscopic surgery (NOTES) is a surgery that enters the natural orifice such as the stomach, vagina, anus, etc. to treat diseases. There is no surgical incision, which reduces the pain and healing process of the patient, and the postoperative recovery is fast. Leave no scars. The existing natural orifice endoscopic surgery is developed slowly due to the limitation of medical devices, and there is no device for performing natural orifice endoscopic surgery through the vagina and anus at present. Contents of the invention [0003] The object of the present invention is to provide a multi-hole endoscopic operation device through the natural cavity, which can keep the pressure in the cavity stable dur...
