Description

Magnet device for taking out magnetic material metal foreign matters in esophagus

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a magnet device for taking out magnetic material metal foreign bodies in an esophagus.

Background

With the widespread use of coin cells in various toys, watches, and remote controls, children inadvertently swallow coin cells into the alimentary canal during play (LITOVITZ T, WHITAKER N, CLARK L. preventive bathing concerns: an analysis of 8648cases [ J ]. Pediatrics,2010,125(6):1178 + 1183.). Button cells are ingested by about 10 out of every million people every year, most of which are children, with one in every 1000 cells that can cause serious injury (COWAN S A, JACOBASEN P. [ Ingemiton of button batteries. epidemiology, clinical signs and therapeutic recogmentations ] [ J ]. Ugeskr Laeger,2002,164(9): 1204-1207.). In general, coin cells are expelled smoothly through the digestive tract, but once they are forced to stay somewhere in the digestive tract, especially in three physiological narrowings of the esophagus, they can cause serious complications and even death (SOCCORSO G, GROSSMAN O, MARTINELLI M, et al.20mm lithium battery consuming an oesophageal performance in a toddler: leaves in diagnostics and treatment [ J ]. Arch Dis Child,2012,97(8): 746-747; ANAND T S, KUMAR S, WADHWAV, ray of microbial contamination of a biochemical of a venous diagnosis [ J ]. 2002-59. the first biological diagnosis [ J ]. 7, 57, et al, J. Button cell intake is most likely to occur in children under 6 years of age, and complications can occur with lithium batteries of 20mm or greater. Complications were estimated to be 0.165% and mortality was 0.04%. The esophagus is the most severely affected organ, the most common Complications of which are esophageal ulceration, perforation, tracheoesophageal fistula, esophageal aortic fistula, etc., but vascular involvement is often fatal (VARGA, KOVACS T, SAXENA A K. analysis of compatibility After tissue in Children [ J ]. Peditar Emerg Care,2018,34(6): 443-. The button cell is stuck in the esophagus, and can cause serious damage in only 2 hours (LITOVITZ T, WHITAKER N, CLARKL, et al. operating Battery-engineering hazard: clinical observations [ J ]. Pediatrics,2010,125(6): 1168-. Symptoms are nonspecific, such as fever, cough, irritability, and dysphagia. Irritability, anorexia, dark stool, and dysphonia can occur in infants; fever, dyspnea, cough, wheezing, watery mouth and vomiting may occur on toddlers (BUTTAZZONI E, GREGORRI D, PAOLI B, et al. symptoms associated with button tires in children: epidemic biological view [ J ]. Int J Peditator Otorhinolaryngol 2015,79(12):2200 + 2207.). Chest X-rays can aid in their diagnosis (YARDENID, YARDENI H, CORAN A G, et al. Severe anatomical great work to button bathing initiation: can it be predicted [ J ]. Pediatr Surg Int,2004,20(7):496 + 501.), once diagnosed, requiring emergency endoscopic retrieval. Complications can be exacerbated, either by limited access to the endoscopist, delayed referrals to a tertiary facility, or delayed anesthesia due to gastric filling (LITOVITZ T, WHITAKER N, CLARK L, et al. For the button battery in the esophagus, even if the button battery is taken out under an endoscope, the button battery is difficult to take out, the button battery is easy to fall off due to the insufficient adhesive force when the foreign body forceps are used for clamping, the basket is more difficult to take out due to the disc shape, the leakage of contents is possibly caused due to the clamping of the foreign body forceps in the taking-out process, or the more serious consequence is caused by the short circuit of the positive electrode and the negative electrode. Under the circumstances, it is urgent to find a simple and effective device for removing metal foreign matters in magnetic materials such as button cells in the esophagus.

The tail end center of the magnet 4 is provided with a cylindrical groove 3, and the front end of the polyvinyl chloride pipe 2 is inserted into the groove 3 and is tightly connected with the inner wall of the groove 3. The guide wire 1 penetrates through the polyvinyl chloride pipe 2, the cylindrical magnetic material 15 at the front end is embedded into the bottom of the groove 3, and the tail end extends out of the polyvinyl chloride pipe 2 and is placed outside the body when in use. The material of the guide wire 1 is nitinol which is highly flexible and durable.

More specifically, as shown in fig. 3, the outer wall of the tail end of the polyvinyl chloride pipe 2 is connected with the side wall of the groove 3 by using self-adhesive, and the front end of the guide wire 1 extends to form a convex cylindrical magnetic material 15 with the diameter of 1.5mm and the height of 2 mm; because the polyvinyl chloride tube 2 is easy to be broken when being implanted into the esophagus, when the guide wire 1 is sleeved into the polyvinyl chloride tube 2, the magnetic material 15 at the front end of the guide wire 1 and the bottom of the groove 3 are attracted by magnetic force, the main function of the guide wire 1 is to guide the magnet 4 into the esophagus, so that the polyvinyl chloride tube 2 is prevented from being broken when being implanted into the esophagus, namely, the guide function is achieved, and meanwhile, the guide wire has a powerful conduction function, namely, the vibration sense is achieved.

The magnetic material metal foreign matter takes the button cell 5 as an example, and the using method of the embodiment comprises the following steps:

the implementation mode is as follows: when the button cell 5 is suspected to be in the esophagus, the front end of the magnet is coated with paraffin oil, and the guide wire 1 is sleeved into the polyvinyl chloride tube 2 and inserted into the groove 3. The device is placed in the oral cavity, and after the device is slightly inserted downwards by 6-8cm, a patient is ordered to swallow, and simultaneously, the lower jaw of the patient is close to the sternal pedicle, so that the radian of the pharyngeal portion is increased. When a patient swallows, the button cell is pushed forward along the situation, when the magnet 4 touches the button cell, the button cell 5 is attracted by the attraction of the magnet 4 (namely, the concave spherical structure 6 is adsorbed on the side surface of the button cell 5), the other end of the device feels slight vibration, the guide wire 1 is pulled out, the polyvinyl chloride pipe 2 is slowly pulled outwards at a constant speed, the polyvinyl chloride pipe 2, the magnet 4 and the button cell 5 are together moved out of the body, and the operation is completed.

The device is placed in the oral cavity, and after the device is slightly inserted downwards by 6-8cm, a patient is ordered to swallow, and simultaneously, the lower jaw of the patient is close to the sternal pedicle, so that the radian of the pharyngeal portion is increased. When a patient swallows, the patient is propelled forwards along the same trend, when the magnet 4 touches the button cell, the button cell is sucked by the suction force of the magnet, the film pressure sensor 7 is transmitted into the display module 10 through the sensor connecting wire 9, the numerical value of the display screen 11 is increased suddenly, or slight vibration is sensed at the other end of the device, after the guide wire 1 is pulled out, the polyvinyl chloride pipe 2 is slowly pulled outwards at a constant speed, and the polyvinyl chloride pipe 2, the magnet 4 and the button cell 5 are moved out of the body together. In the moving-out process, the pressure value is continuously monitored to be changed, if the pressure at a certain position is suddenly reduced, the button battery is separated from the magnet, and the button battery needs to be sucked again. And after the button cell 5 is taken out, the switch 12 of the display module 10 is closed, and the operation is finished.
