Description

Biliary tract calculus-taking basket combined with calculus crushing

Technical Field

The utility model belongs to the technical field of the biliary tract calculus removing technology and specifically relates to a biliary tract calculus removing basket combined with gravel.

Background

In the classification of surgical diseases in China, biliary calculi have high morbidity, millions of patients are newly increased every year, and the biliary calculi bring great pain to the patients. At present, the biliary tract calculus is usually required to be jointly removed by choledochoscope calculus breaking, and the specific process is as follows: the rubble seal wire of hydroelectricity rubble appearance gets into the biliary tract through the choledochoscope and aims at the calculus and carry out the rubble, gets the stone basket and gets the biliary tract through the choledochoscope and get the stone, because rubble seal wire and get the stone basket separately, need put into after extracting the rubble seal wire and get the stone basket again, then extract and get the stone basket and put into the rubble seal wire again, repeat like this, waste time and energy.

The Chinese patent application: CN206621397U discloses a novel stone and gravel taking basket, which is composed of a handle, a connecting pipe, a spring pipe, a basket handle, a push rod, a pushing wire, a basket body, a net head and the like; the connecting pipe is connected with the spring pipe in a welding mode, and the connecting pipe is connected with the handle through a screw to form a conveying outer pipe; the net head is connected with the net basket body, the net basket body is connected with the pushing wire, the pushing wire is connected with the push rod, and the push rod is connected with the net basket handle to form a conveying component; the conveying part is nested in the conveying outer pipe cavity channel, and stone taking is carried out by moving the basket handle; and rotating the rocker counterclockwise to perform stone breaking. The device mainly solves current bile duct calculus and gets stone basket function singleness, can not combine together the rubble with getting the stone, and prevent to get the problem that the calculus of stone in-process is incarcerated, though the device combines together the rubble with getting the stone, but at the in-process of actual operation, the device is when the rubble, through the anticlockwise rotation rocker, make the pivot motion, drive propelling movement silk back motion, thereby the basket body is the same back motion, finally with the calculus breakage, so the rubble mode that the device took mainly lets the basket body carry out the closure, crush through external pulling force to the stone that is located the basket body, so when the stone hardness that meets is than hard or the stone volume when very big, the device is getting up just very inconvenient in the use, can not reach fine rubble effect.

The Chinese patent application: CN207693636U discloses a choledochoscope stone-taking basket, including stone-taking basket, nipper and microwave line, still set up in the basket pipe box of stone-taking basket and communicate to the nipper hole and the microwave line hole of basket pipe box front end, the both sides of basket pipe box are connected with nipper pipe and microwave line pipe, and the hole of nipper pipe and the nipper hole of basket pipe box in communicate, the pincers end of nipper and the electric head end of microwave line all set up in the outside of basket pipe box, and the work end of nipper extends the outside of nipper pipe through nipper hole and nipper pipe, and the work end of microwave line extends the outside of microwave line pipe through microwave line hole and microwave line pipe. The device mainly solves the problems that in the prior art, when microwave lithotripsy is carried out, stones cannot be fixed, and when the microwave lithotripsy is carried out, the stones move, a microwave probe possibly collides with the wall of a bile duct to cause damage and bleeding of the wall of the bile duct.

Therefore, in view of the above, there is a need for a biliary calculus-removing basket capable of effectively breaking stones, removing stones or stone fragments, shortening the operation time and reducing the trauma of patients, and no report on the biliary calculus-removing basket for the novel combined breaking stones is found at present.

Disclosure of Invention

The utility model aims at providing a biliary tract calculus-taking basket combined with calculus crushing.

In order to achieve the purpose, the utility model adopts the technical proposal that:

the utility model provides a stone basket is got to biliary tract of joint rubble, includes handle, connecting portion, sheath pipe and basket, the inside of sheath pipe is provided with the silk guide chamber, the silk guide chamber inner wall of hugging closely the sheath pipe, the inside in silk guide chamber still is provided with the hydraulic and electric rubble seal wire.

In the biliary calculus removing basket combined with calculus crushing, as a preferred scheme, the electric head end of the calculus crushing guide wire is arranged outside the sheath tube, and the working end of the hydraulic-electric calculus crushing guide wire penetrates through the guide wire cavity in the sheath tube and extends to the outside of the sheath tube.

In the biliary calculus removing basket for combined calculus crushing, as a preferable scheme, the hydraulic-electric calculus crushing guide wire extending to the working end outside the sheath tube has an extension length of 0.4-0.6 cm.

The utility model has the advantages that: the utility model discloses simple structure, convenient to use, it mainly through with the rubble seal wire of electrohydraulic stone crusher melt into get the sheath pipe wall of stone basket in, need not to make a round trip to change the effect that equipment alright directly take out the calculus behind the rubble to both practice thrift operating time, also reduced operating personnel's work load, also avoided simultaneously causing the unnecessary injury to the patient because of making a round trip to trade the instrument at the operation in-process.
