The utility model discloses a kind of gastric cavity plugging catheters of gastrostomy in the medical instrument technical field, the device increases plugging balloon and sealing clamping piece, can be held by inside and outside, hold stomach wall and skin to position the device, while plugging balloon seals and isolates the puncture of stomach wall inside gastric cavity, effectively avoid gastric juice to flow out, avoid gastric juice to overflow along the puncture and cause skin burning;Positioning baffle is also increased, can be unfolded inside duodenum, positioning baffle can position nutrition tube, avoid nutrition tube to slide and separate, can also effectively block pylorus, effectively avoid enteric digestive juice to enter stomach, and do not hinder gastric juice to flow into intestine normally, and by pressure relief port and pressure relief pipe, stomach is conveniently decompressed, effectively avoid that pressure is too high and nutrition liquid is refluxed to esophagus.

This invention discloses a pediatric double-balloon catheter for esophageal and gastric pressure monitoring, comprising an outer sheath and an inner core tube. Both ends of the outer sheath are open. The inner core tube is slidably inserted into and passes through the outer sheath. One end of the outer sheath is provided with a dynamic locking component for fixing the inner core tube, and the inner circumferential wall of the other end of the outer sheath is in a sealed sliding fit with the outer circumferential wall of the inner core tube. An esophageal pressure inflation / measurement connector is located on the exterior of the outer sheath near the dynamic locking component, and an esophageal pressure balloon is circumferentially sealed on the exterior of the outer sheath away from the dynamic locking component. This invention solves the clinical problem of traditional fixed-spacing catheters, which cannot simultaneously ensure accurate placement of the esophageal balloon in the lower esophagus and complete placement of the gastric balloon within the gastric cavity, making the same catheter applicable to a wide age range from newborns to adolescents.

The application discloses an application of an endoscopic continuous suturing device in preparation of a gastric plication suturing medical instrument, and the endoscopic continuous suturing device comprises a suture wire with uniformly distributed barbs, a plurality of titanium clips and a pushing device, the suture wire is 6-10 cm long, and the two ends of the suture wire are respectively provided with a front end connecting ring and a rear end connecting ring; a sheath pipe is arranged at the position close to the rear end connecting ring of the suture wire; the titanium clip is used for clamping and fixing the gastric mucosa tissue and the suture wire; the pushing device is used for tightening the suture wire and comprises a traction steel wire, an inner push tube and an outer sheath tube which are sleeved from inside to outside and slide; a metal hook is arranged at the front end of the traction steel wire; two operation handles are arranged at the rear end of the pushing device and are used for respectively controlling the inner push tube and the traction steel wire to move forward and backward. The gastric mucosa is sutured by the barbed suture wire, the long-term stability of the gastric wall folding is ensured, the barbed suture wire cooperates with the titanium clip to realize step-by-step pre-tightening, and the gastric cavity volume can be accurately controlled.
