Abstract

The utility model discloses a gallstone withdrawing device, which is characterized by comprising an outer sleeve, an operating handle, a limiting plate, a guide line and a gallstone-withdrawing mesh fence. The operating handle is arranged on the limiting plate; the limiting plate is arranged in a groove at the bottom end of the inner wall of an outer sleeve; the limiting plate can move and rotate in the groove vertically; the guide line is arranged in the outer sleeve; one end of the guide line is connected with the limiting plate; the other end of the guide line is connected with the gallstone-withdrawing mesh fence; the gallstone-withdrawing mesh fence is arranged at the outer part of the outer sleeve; and the bottom end of the gallstone-withdrawing mesh fence is connected with the guide line. The gallstone withdrawing device is concise in operation mode, greatly reduces the operation time, improves the work efficiency, and reduces the work intensity of patients and users. With the composite design of the limiting plate and the groove, the gallstone withdrawing device can rotate the gallstone-withdrawing mesh fence in the operation according to the actual situation, and leads the gallstone to be capable of smoothly entering the gallstone-withdrawing mesh fence and to be withdrawn.

Description

The cholelithiasis stone taking device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of netted stone taking device that cholelithiasis is got stone that is used for.

Background technology

Along with progress of science and technology and development in recent years, for a large amount of clinical reports of all disadvantages of postcholecystectomy, find that gallbladder has complicated and important function very, indispensable and alternative.As everyone knows, the side effect of postcholecystectomy or harm should attract great attention, and it directly has influence on patient's quality of life, even jeopardize patient's life.After gallbladder removal, gallbladder has lost buffered effect for the fluid pressure in the bile duct, has caused the common bile duct internal pressure to increase, caused the common bile duct underwent compensatory enlargement, from and make the gallbladder flow velocity degree in the common bile duct slack-off, and vortex or eddy current take place, the latter is the important theory that forms cholelithiasis.In this case, gallbladder removal is treated cholelithiasis, has on the contrary avoided the anxiety of postoperative cholelithiasis " recurrence ", but causes the misfortune of " growth choledocholithiasis "; The tool danger of which kind of calculus? which is more important, self-evident.

In the Therapeutic Method about cholelithiasis, protecting gallbladder and cutting between the gallbladder, exist a world of difference, scope is protected gallbladder and is got the physiological function that stone has kept gallbladder; Cut gallbladder and get stone and lost gallbladder, lost the gallbladder physiological function, can cause a series of physiological barrier, even the possibility that causes colon cancer is arranged; It is not high to protect behind the gallbladder lithotomy relapse rate of cholelithiasis, is clinically opened that this is secret and confirm by the modern times.It is fool proof that guarantor's gallbladder is got stone, and those complication of gallbladder removal can not be arranged.

Along with the modern medicine science and technology development, these important digestive organs of gallbladder have been had further understood, concentrated except having, shrink and regulate the effect of buffering pressure of biliary tract, the still chemistry and the immunologic function organ of a complexity.Not dispensable gallbladder, but crucial digestive organs, so should not abolish easily! Certainly, for atrophy of gallbladder, gallbladder has not had function, or gallbladder suspicious malignant person, should certainly excise gallbladder, removes focus.

In today of scientific and technical high development, gallbladder removal theoretical 100 years later today, re-recognize " this theory ", just be worth conscientiously having discussed, if analogize, should be there calculus just should excise which internal organs by which internal organs with this theory? it seems that this kind opinion just seems too cruel, too simple today.For the way in this direct excision affected part, processing mode sometimes is difficult to allow several head of people.

Traditional stone equipment of getting is easy to destroy mucous membrane of gallbladder in gallbladder, get cubic meter of stone formula comparison patternization for difform calculus in addition, is unfavorable for that the special shape calculus gets stone; The time of operation is generally all long, can cause adverse influence to the patient like this; In operation, more complicated is unfavorable for using.

Summary of the invention

This utility model is at the proposition of above problem, and develops a kind of cholelithiasis stone taking device, and existing product is upgraded, and provides a kind of therapeutic modality more easily in treatment.

Technical solution of the present utility model is achieved in that

A kind of cholelithiasis stone taking device is characterized in that being made of trocar sheath, operating grip, limiting plate, lead and lithotomy net hurdle; Described operating grip is installed in the above limiting plate of limiting plate and is installed in the groove of outer sleeve inner wall bottom, and limiting plate can move up and down in groove, rotate; Described lead is installed in the trocar sheath, and an end is connected with limiting plate, and the other end is connected with the lithotomy net hurdle; Described lithotomy net hurdle is installed in the trocar sheath outside, and bottom, lithotomy net hurdle is connected with lead.

The outside, described trocar sheath bottom is equipped with Handleset.

Owing to adopt above technical scheme, the utlity model has following advantage:

1, lithotomy net of the present utility model hurdle is similar with the anatomical shape of gallbladder in shape, and is little to injury of human;

2, this utility model is quick and easy on lithotomy method;

3, this utility model is in getting the stone process, and very little to the injury of mucous membrane of gallbladder, effect is remarkable;

4, this utility model adopts limiting plate in the composite design of groove, makes gallbladder lithotomy net hurdle section in operation rotate according to practical situation, makes calculus can enter the lithotomy net hurdle smoothly for taking out;

5, this utility model is succinct on mode of operation, has reduced operating time greatly, has improved work efficiency, reduces the working strength of patient and user.
