Example 1

Referring to fig. 1, 2 and 6, the endoscopic cholecystostomy device provided by the present embodiment includes a connecting tube 1, a gas distribution tube 2 and an inhalation tube 3 which are communicated with each other to form a three-way structure; the end part of the connecting pipe 1 is communicated with a suction pipe 4 which can be inserted into an endoscope biopsy pipeline 91, the top part of the connecting pipe 1 is fixedly connected with a first finger ring 51, and the bottom part of the connecting pipe 1 is fixedly connected with a second finger ring 52; wherein, the air suction pipe 3 is in a ladder-shaped structure with the diameter gradually reduced towards the pipe orifice and is used for connecting a negative pressure suction device.

In the embodiment, when the cystic duct calculus removal is performed, the suction tube 4 extends into the endoscope along the biopsy channel 91 of the endoscope, then extends out from the head end 92 of the endoscope, then the extended suction tube 4 is close to the target cystic duct calculus, then the negative pressure suction device is opened, the index finger is buckled into the first ring 51, the middle finger is buckled into the second ring 52, and the thumb is used for plugging the orifice of the gas distribution tube 2, so that the orifice of the suction tube 4 can generate suction force to suck the cystic duct calculus under the action of the negative pressure suction device; finally, an operator holds the three-way structure formed by the connecting pipe 1, the gas distribution pipe 2 and the air suction pipe 3 to withdraw the suction pipe 4, so that the calculus can be dragged out of the cystic duct, and after the calculus is dragged out, the thumb is released, so that the negative pressure state in the three-way structure can be broken, the suction force of the mouth of the suction pipe 4 is lost, and the cystic duct calculus is put down.

It should be noted that the inner diameter of the gas-distributing pipe 2 is preferably larger than the inner diameter of the suction pipe 4, so that more gas flows in from the gas-distributing pipe 2, and the negative pressure state in the three-way structure can be broken more rapidly, so that the opening of the suction pipe 4 can put down the cystic duct stones in time, and the time is saved.

On the basis of the embodiment, a sucker 8 in an outward-expanding horn mouth shape can be further arranged on the edge of the opening of the gas distribution pipe 2, the sucker 8 is made of silica gel, and when the opening of the gas distribution pipe 2 is blocked by a thumb, the sucker 8 can be better attached to the head of a thumb, so that the sealing performance of the thumb on the opening of the gas distribution pipe 2 is improved, and the suction effect of the suction pipe 4 on concretes is better; meanwhile, the sucker 8 can increase the contact surface between the pipe orifice of the gas distribution pipe 2 and the thumb head, so that the comfort level of the thumb is improved.

Further, in order to prevent the palm from slipping when the suction tube 4 is retracted, the outer surfaces of the connecting tube 1, the gas distribution tube 2 and the air suction tube 3 may be subjected to an anti-slip treatment, such as painting an anti-slip paint on the surfaces thereof or being made of a rubber material, so that the friction coefficient between the palm and the connecting tube 1, the gas distribution tube 2 and the air suction tube 3 can be prevented from slipping when the palm is dragged.

Example 2

Referring to fig. 3 to 5, the endoscopic cholecystectomy device provided in this embodiment is different from embodiment 1 in that: the connecting pipe 1 is provided with a strip-shaped opening 11 extending along the length direction of the connecting pipe 1 in a vertically penetrating manner, and a sliding pipe 6 is inserted in the connecting pipe 1 in a sliding manner; one end of a sliding tube 6 is communicated with a suction tube 4 extending into the connecting tube 1, the other end of the sliding tube 6 is communicated with an air suction tube 3 through a corrugated tube 7, the corrugated tube 7 is a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and stretching direction, the corrugated tube 7 can freely extend and shorten along with the sliding of the sliding tube 6, and meanwhile, the corrugated tube 7 also ensures the sealing performance of a three-way structure formed by the connecting tube 1, the air distribution tube 2 and the air suction tube 3; in addition, the first finger ring 51 and the second finger ring 52 both penetrate through the corresponding strip-shaped opening 11 and are fixedly connected with the slide tube 6.

In addition, when the suction tube 4 extending from the head end 92 of the endoscope is close to the target cystic duct calculus, in order to improve the moving stability of the suction tube 4 and the accuracy of the approaching of the target cystic duct calculus, the end of the connecting tube 1 can be abutted against the opening of the biopsy channel 91 of the endoscope, then the first finger ring 51 and the second finger ring 52 can be moved along the strip-shaped opening 11 by bending or extending the forefinger and the middle finger, and the first finger ring 51 and the second finger ring 52 can be moved to adjust the length of the suction tube 4 extending from the head end 92 of the endoscope in the telescopic range of the corrugated tube 7 through the sliding tube 6 so as to control the calculus removing range of the suction tube 4 in the cystic duct; and because the sliding tube 6 is inserted in the connecting tube 1 in a sliding manner, the sliding tube 6 can slide to drive the suction tube 4 to be stably and accurately close to the target cystic duct calculus, and the calculus removing efficiency is improved.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
