Abstract

The invention relates to the technical field of medical apparatus, in particular to a capsule endoscope pusher which comprises a core rod. The capsule endoscope pusher is characterized in that the core rod is installed in a pushing piston rod, the back end of the pushing piston rod is installed in the back end of a sheath pipe, the front end of the pushing piston rod is provided with an eccentric piston ring, the front end of the sheath pipe is provided with an eccentric capsule endoscope chamber, and the eccentric piston ring is correspondingly arranged in the eccentric capsule endoscope chamber at the front end of the sheath pipe. The capsule endoscope pusher is simple and safe to operate, and the capsule endoscope can be directly pushed into the descending part of duodenum without passing through esophagus and stomach, so that mucous membranes at all sections of small intestine and large intestine can be checked completely, timely and safely as required. The invention eases the contradiction among patients, hospitals, dealers and firms, relieves pains of patients and greatly facilitates the clinic.

Description

Capsule endoscope pusher

Technical field

The present invention relates to the medical apparatus technique field, particularly relate to a kind of capsule endoscope pusher.

Background technology

Small intestinal is long and tortuous, overlapping, and it is fast again to wriggle, and various traditional inspection method sensitivity, specificitys are lower.The disease of intestine onset is hidden more, clinically shows as stomachache, melena, anemia etc. more, does not have specificity, fails to pinpoint a disease in diagnosis easily, mistaken diagnosis.Therefore,, when having got rid of gastroduodenal and large intestine disease, promptly should take into full account the possibility of disease of intestine, and check accordingly patient that above-mentioned symptom is arranged.In recent years, for some traditional methods of small bowel disease improve both at home and abroad, and promoted small intestinal mirror, capsule endoscope and Imaging Techniques gradually, stepped a gratifying step for improving the diagnosis of small intestine disease level.But because restriction of technical equipment such as small intestinal mirror and inspection fee are expensive, and painful during inspection, can not be widely used in clinical.Widely use at present both at home and abroad through the inspection of capsule endoscope to disease of intestine, can dynamically observe each disconnected mucosa situation of small intestinal, be the effective ways of inspection disease of intestine.But it is not enough below the inspection of traditional capsule endoscope exists.

(1), long dead time at gastric behind part patient's swallowable capsule scope, the scope electric quantity consumption is too much, inspection small intestinal that can not be comprehensive, timely, complete; The Clinics and Practices of incuring loss through delay the patient; Old people particularly, part of diabetes mellitus patient, gastroparesis patient; The patient of undergrown patient of congenital pylorus and pyloric obstruction is more difficult during the capsule endoscope inspection.

(2), stagnate fully at gastric behind the swallowable capsule scope, have certain empirical doctor and take out, increase patient's misery through endoscopic technic, and consumption worker, time-consuming, even not successful.

(3), the capsule endoscope price is more expensive, in case inspection is unsuccessful, may cause the contradiction between patient, hospital, distributor, the company.

Summary of the invention

The objective of the invention is to avoid the deficiency of prior art that a kind of capsule endoscope pusher is provided; It can once insert capsule endoscope; Directly capsule endoscope is pushed into duodenal capsule endoscope pusher without esophagus, stomach, thereby effectively solve the problem that exists in the prior art.

For realizing above-mentioned purpose; The technical scheme that the present invention takes is: described capsule endoscope pusher, comprise core bar, and be characterized in also including: described core bar is installed in and pushes in the piston rod; The rear end that pushes piston rod is installed in the epitheca pipe rear end; The front end that pushes piston rod is provided with eccentric piston ring, and the front end of epitheca pipe is provided with eccentric capsule endoscope storehouse, and eccentric piston ring correspondence is arranged in the eccentric capsule endoscope storehouse of epitheca pipe front end.

Described core bar front end is the tapered guide head, and the core bar front end feeds the eccentric capsule endoscope storehouse of epitheca pipe front end and stretches out, and the core bar rear end is slidingly installed with the propelling movement piston rod.The rear end of described propelling movement piston rod and epitheca pipe rear end are slidingly installed.The rearward end of described propelling movement piston rod and epitheca pipe also is provided with handle.

The eccentric capsule endoscope storehouse of described epitheca pipe front end is a cylinder body shape, and its diameter is less than or equal to 12mm, and length is smaller or equal to 15mm, described epitheca pipe, and pushing piston rod and core bar is silica gel tube, epitheca pipe outside is provided with scale.

The invention has the beneficial effects as follows: described capsule endoscope pusher; Its safety simple to operate; Capsule endoscope directly pushes capsule endoscope into descendant duodenum without esophagus, stomach, can check each section mucosa of small intestinal, large intestine comprehensively, in time, safely, as required.Capsule endoscope inspection success rate is 100%, has relaxed the contradiction between patient, hospital, distributor, the company.Alleviated patient's misery, be very easy to clinical.

The specific embodiment

Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.

See Fig. 1, Fig. 2, shown in Figure 3; Described capsule endoscope pusher comprises core bar 6, is characterized in also including: described core bar 6 is installed in and pushes in the piston rod 5; The rear end that pushes piston rod 5 is installed in epitheca pipe 4 rear ends; The front end that pushes piston rod 5 is provided with eccentric piston ring 3, and the front end of epitheca pipe 4 is provided with eccentric capsule endoscope storehouse 2, and eccentric piston ring 3 correspondences are arranged in the eccentric capsule endoscope storehouse 2 of epitheca pipe 4 front ends.

Described core bar 6 front ends are tapered guide head 1, and core bar 6 front ends feed the eccentric capsule endoscope storehouse 2 of epitheca pipe 4 front ends and stretch out, and core bar 6 rear ends are slidingly installed with propelling movement piston rod 5.The rear end of described propelling movement piston rod 5 and epitheca pipe 4 rear ends are slidingly installed.The rearward end of described propelling movement piston rod 5 and epitheca pipe 4 also is provided with handle 8.

The eccentric capsule endoscope storehouse 2 of described epitheca pipe 4 front ends is a cylinder body shape, and its diameter is less than or equal to 12mm, and length is smaller or equal to 15mm, described epitheca pipe 4, and pushing piston rod 5 is silica gel tube with core bar 6, epitheca pipe 4 outsides are provided with scale.

Described capsule endoscope pusher, endoporus 7 can pass through guiding steel wire in the middle of its core bar 6, when capsule endoscope pushes; As the capable gastroscopy of routine, guiding steel wire is inserted descendant duodenum, withdraw from gastroscope; Then with the capsule endoscope pusher that capsule endoscope is housed; Slowly get into descendant duodenum along seal wire, go gastroscopy again, confirm that it is that available capsule endoscope pusher pushes capsule endoscope into descendant duodenum and gets final product that capsule endoscope reaches pyloric cap.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
