Abstract

The utility model relates to a Z-formed and hard colonoscope composed of annularly distributed optical fibre and cold light source and belongs to medical instruments with new structure. The structure is characterized in that a hard circular tube is provided with an interlayer. Light conducting fiber is arranged in the interlayer, the light conducting fiber is sealed with the circular tube and the tail section by resin, and the light conducting fiber, the circular tube and the tail section are connected into integration. The light cutting end of the fiber can be provided with a handle, the interior of which is provided with a lamp bulb, and the light cutting end of the fiber can also be matched with a cold light source. The spy hole of the colonoscope is big, the light irradiation is strong, the utility model has the advantages of the original Z-formed, hard colonoscope and the fiber colonoscope, and the picture of the focus can be taken directly. The laser therapy can be led in.

Description

Z-formed, hard colonoscope composed of annularly distributed optical fibre and cold light source

The present invention relates to a kind of improved medical apparatus and instruments, particularly the hard romanoscope that the human body rectum is undergone surgery to the sigmoid colon position.

A kind of hard romanoscope of common use is arranged, and is that the auxiliary top guide of a straight metal circular tube utilization is sent into enteric cavity, withdraw from top guide after, the top that the thin bar that reuse one radicle is equipped with luminous small electric bulb is sent cylinder to is done illumination and is finished necessary operation.Because thin bar is placed in the handle hole, there is obstacle the visual field, inconvenient operation, and China Suzhou Medical Instruments Factory makes this product.

Have fibre-optic medical endoscope, on structure, can be divided three classes:

1, in the straight hard tube fiber waveguide beam is housed or has coherent fiber bundle concurrently and handle hole becomes one.

2, insert earlier stereoplasm tube, the back is sent into fibre bundle in manage and is used for illumination or passes picture.

What 3, insert is can be with the flexible hose of cavity bending, and there is segment hard top guide on the pipe top.Fibre bundle and corresponding handle hole are arranged in the pipe.

The medical fibre endoscope of above-mentioned three class formations, for operating theater instruments in sigmoid colon and rectum topical diagnosis, it is too little perhaps to feel to operate the aperture, and perhaps illuminator makes complex operation, and there are similar products in Japanese Ou Lin Bath company and Shanghai medical optical instrument factory.

In addition, China People's Telecon Publishing House published the 153rd page of outstanding " optical fibers " book in the long room of Japan and U.S. in 1974, for the intestinal mirror simple narration was arranged.

The objective of the invention is to provide a kind of hard romanoscope that has improved illuminator, it has not only kept big operation aperture, and is accessible in the visual field, easy to operate, and distribution of light is even.

The romanoscope of this hard is such: can send into enteral and partly be one straight, form pipe with dissection by pipe in a hard outer tube and the hard.The optical fiber of packing in the interlayer.One end of fiber is lined up circular as the bright dipping end at the about 1 centimeter inwall of locating to paste outer tube of distance outer tube front end.On 1 centimeter long outer tube wall, reflective mirror is arranged.The cylinder of staying the outer rear end of cavity and be a band tapering with can send into intravital pipe riveting and be knotted.The other end of fiber holds together into a branch of drawing from side-wall hole and makes the light source receiving terminal in the awl tube.The two ends of fiber isolate fiber with resin-sealed with outside air in interlayer.Said structure becomes one, and can not separate.

The incident end is provided with and can connects with the handle tube that small electric bulb is equipped with in inside, also is suitable for and connects cold light source.

The romanoscope of this fiber hard can be made the people that two kinds of specifications adapt to different builds.

1, the external diameter φ 15mm of pipe can insert length 150mm.

2, the external diameter φ 20mm of pipe can insert length 300mm.

This hard second shape intestinal mirror, removed former hard romanoscope lamp stand and put obstacle in tube, avoided intestinal fiberscope peephole smaller defect, fiber incident end can connect small electric bulb and cold light source, can in peephole, directly take pictures, can also import laser therapy focus.Because simple in structure, this mirror cost is low.

The SIG concrete structure of this fiber hard is provided by accompanying drawing.

Fig. 1 is the mobile jib outside drawing.

With reference to Fig. 1, (1) be to stretch into intravital metal outer pipe, (2) be to stay the cylinder that there is tapering external rear end, (3) be the light source receiving terminal double as mounting or dismounting handle bolt of tapered cylinder sidewall, dome (4) is from the inner chamber of awl tube (2) back-end sealing awl tube (2), the position that the scale of outer tube-surface (5) is convenient to grasp focus.

Fig. 2 is the mobile jib cutaway view.

With reference to cutaway view 2, tapered cylinder (2) and outer tube (1) riveted joint, there is a dome (4) of riveting with interior pipe (5) awl tube (2) rear end the sealing of awl tube inner chamber.Grow about 1 centimeter of interior pipe (5) with the front end of the concentric outer tube of interior pipe (5) (1), and form interlayer between interior pipe (5) and the outer tube (1), fibre bundle (6) is housed in the interlayer.The front end of one end of fibre bundle (6) and interior pipe (5) is isometric, and lines up circular as light output end (7) in the periphery of interior pipe (5).The other end of fibre bundle (6) holds together into a branch of in awl tube (2), draws as the light source receiving terminal from the bolt (3) that mesopore is arranged at awl tube (2) sidewall.The front end of outer tube (1) is provided with reflective mirror (8) to the inwall of ring-type bright dipping end (7) this section outer tube (1), and emergent light is evenly distributed after reflection.

Claims

1, medical hard romanoscope can be sent into by front end that pipe (5), the rear end that stays in the body have the cylinder (2) of tapering, fibre bundle (6), awl tube (2) sidewall that is contained in interlayer and the awl tube (2) to have the bolt (3) of a light source receiving terminal double as mounting or dismounting handle, detachable handle tube to form in round outer tube with dissection (1) in the human body, the circle, it is characterized in that:

A, described front end can be sent into intravital metal circular tube and form interlayer by hard, straight, concentric outer tube (1) and interior pipe (5), in the interlayer between outer tube (1) and the interior pipe (5) fibre bundle (6) are housed,

The front end of one end of b, this fibre bundle (6) and interior pipe (5) is isometric and line up circular as light output end (7) at the outer wall of interior pipe (5), the other end of fibre bundle (6) holds together into a branch ofly to draw as light source receiving terminal (3) from sidewall in awl tube (2)
