Description

Endoscopic lithotripter snare

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an endoscopic lithotripter.

Background

In the prior art, gastrolithiasis refers to a lump that is fed with a certain food, item or foreign matter, and is not retained and agglomerated in the stomach by passing through the pylorus, so is also called intragastric caking. Most gastric stones can be treated by lithotripsy through a conventional snare under a litholytic stone or a gastroscope, but for large-size and hard-texture gastric stones, the implementation effect is poor by adopting the conventional snare under the gastroscope, and for large-size and hard-texture gastric stones, a doctor usually adopts surgery or laparoscope to take out the gastric stones, so that the wound surface of a patient is large and the cost is high.

The former snare includes the metal pipe body, and metal pipe body rear end fixedly connected with handle has the smooth handle of fore-and-aft slip on the handle, has the wire fixed knob on the smooth handle, alternates in the metal pipe body and has the wire, and the wire exposes the wire cover at the metal pipe body front end, and the wire is connected with the wire fixed knob at metal pipe body rear end, and the stone position is pulled in the human body through the repeated cover of wire cover, makes it broken, drops, realizes the treatment. The defects are that: firstly, use the snare rubble under the scope, because the gastrolith is hard, the snare wire cover is the ring cover that welds, and snare wire cover is easy to break, leads to the snare to consume much to in the stomach is detained after the wire cover fracture, still needs to take out in addition, increases medical expenses, increases operation time and brings the misery to the patient. The wire sleeve is a welded ring sleeve, the size of the ring sleeve is not adjustable, the snare wire sleeve is smaller, and larger gastrolith can not be sleeved in, so that the use is affected. Secondly, when the snare is sent into the stomach, the metal wire sleeve and the metal tube body are exposed, so that an endoscope is easily damaged and mucous membrane in the body is easily injured.

The Chinese patent specification 2019 discloses an utility model patent named as a novel gastric calculus lithotripter on the date 07 and 05, wherein the patent number is ZL201711438455.1, and the novel gastric calculus lithotripter comprises a wire saw, a wire snare, a head anti-lashing bolt, a sleeve hose, a tail anti-lashing bolt, a rotary fixing screw, a metal fixing groove, a handle a, a handle b and a wire; the front part of the outer sleeve soft rod tube is provided with a head part anti-reeving bolt, the rear part of the outer sleeve soft rod tube is provided with a tail part anti-reeving bolt, the front part of the metal wire is provided with a metal wire snare with a metal wire saw, the wire heads at the two ends of the tail part of the metal wire penetrate into the outer sleeve soft rod tube respectively from two holes of the head part anti-reeving bolt, then penetrate out from two holes of the tail part anti-reeving bolt of the tail part of the outer sleeve soft rod tube, a handle a and a handle b with rotary fixing screws and metal fixing grooves are arranged, and the wire heads at the two ends of the tail part of the metal wire penetrate into the metal fixing grooves of the handle a and the handle b respectively

And then the metal fixing groove is fixed by a rotary fixing screw. When in use, the metal wire snare is used for covering the calculus, and the handle a8 is held and pulled by two hands to form the metal wire sawing calculus. The defects are that: the outer sleeve soft rod tube 4 is only connected with the handle a8 by adopting metal wires, so that the outer sleeve soft rod tube 4 is in soft connection, and people still need to hold the outer sleeve soft rod tube 4 when in use, so that the outer sleeve soft rod tube is inconvenient to use, and wastes time and labor. There is also the disadvantage that the wire and the outer flexible shaft tube 4 are exposed and easily hurt the endoscope and the mucous membrane in the body when the snare is fed into the stomach.
