Embodiment 1

[0035] This embodiment provides a small-diameter endoscope driven by an external magnet, see attached Figure 1-8 , including: a capsule head 1, a channel sealing tube 2, a connecting body 3, a cable 14, a water / air tube 16 and a tool channel tube 12;

[0036] See attached Figure 2-4 , the capsule head 1 includes: a head sealing tube, a head housing 4, a ring magnet 11, a camera module 13, a camera sealing end cap 5 and a water / air nozzle 6;

[0037] The head shell 4 is composed of a cylindrical structure 7 and a conical structure 8 docked thereto. Both the cylindrical structure 7 and the conical structure 8 are split structures, that is, the cylindrical structure 7 consists of two semicircular structures. Cylinders are butted to form, and the conical structure 8 is formed by the butt joint of two semicircular truncated cylinders, and the split structure is convenient for installing internal components; the inside of the cylindrical structure 7 is processed with an annular b...

Embodiment 2

[0055] Present embodiment: provide another kind of small-diameter endoscope driven based on external magnets, except that the structure of the head housing 4 is different, all the other parts and the connection relationship are the same;

[0056] In this embodiment, the head shell 4 is composed of two semi-cylindrical structures 9 docked, see the attached Figure 9 , the head housing 4 is processed with a cylindrical cavity with both ends closed for installing the ring magnet 11, and three axial through holes are respectively processed in the head housing 4, wherein the axial through holes for installing the tool channel pipe 12 are processed. The through hole passes through the central hole of the ring magnet 11, and the two axial through holes for installing the water / air pipe 16 and the cable 14 are located outside the ring magnet 11;

[0057] During installation, the ring magnet 11 is first installed in a semi-cylindrical structure 9 of the head housing 4, and then the cam...

Abstract

The invention discloses a small-pipe-diameter endoscope based on drive of external magnets. The small-pipe-diameter endoscope is characterized by comprising a capsule-shaped head part, a channel sealing pipe, a connector, a cable and a tool channel pipe, wherein the capsule-shaped head part comprises a head sealing pipe, a head shell, an annular magnet and a camera module integrated with a light source; the annular magnet is coaxially mounted in the head shell, the camera module is mounted in a through hole of the head shell, one end of the cable is connected with the camera module, and the other end of the cable is connected with an external power supply control device after passing through a cable connector of the connector; one end of the tool channel pipe is mounted in the through holeof the head shell, and the other end of the tool channel pipe is connected with a common channel of a tool channel connector and a suction interface of the connector; the head sealing pipe covers theouter part of the head shell, and the channel sealing pipe covers the tool channel pipe and the cable between the head shell and the connector; the endoscope performs mobile control through the external magnetic field, and can realize the painless and omni-bearing controlled observation.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a small-diameter endoscope driven by an external magnet. Background technique [0002] The traditional endoscope is an intubation endoscope, which mainly enters the human body through passive insertion. Since the end of the intubation endoscope is equipped with an eyepiece, a cold light source and an optical fiber connected to the cold light source, the intubation endoscope The diameter of the endoscope is relatively large, and because it is inserted into the human body, the strength of the intubation endoscope is relatively high, and it will bring strong pain to the patient during the insertion process. Therefore, the general patient only has When the symptoms are very obvious, endoscopic examination will be done, thus delaying the best time for treatment. Different from intubation endoscopes, capsule endoscopes are now used in medical examinations, whic...
