Description

Drum-type endoscope transparent cap

Technical Field

The utility model relates to the technical field of endoscopes, in particular to a drum-type endoscope transparent cap.

Background

With the development of medical technology, endoscopes have become a common medical instrument for observing and acquiring images of the digestive tract and organs. A doctor can directly acquire images in the digestive tract through an endoscope so as to be capable of diagnosing and treating digestive system diseases. When the endoscope is used, the lesions on the back and back of the intestinal folds are shielded by the folds, so that a visual blind area is formed, an operator cannot directly look, blind operation is easy to injure by mistake or cause missed diagnosis and misdiagnosis, and a plurality of difficulties are brought to clinical operation and treatment.

At present, a transparent cap is sleeved at the front end of an endoscope to maintain a clear operation view, visual diagnosis basis is provided for endoscopy, the traditional endoscope has the defects of thinness and smooth outer wall, and the following defects are overcome:

1. when the fold is pressed down, the front end of the endoscope is too close to the intestinal wall, so that the visual field becomes red and the operation space without instruments is formed;

2. if the endoscope is retracted slightly, the endoscope body is very easy to slip from the fold, and the better functions of pressing the fold, exposing the back of the fold and the rear view can not be achieved;

3. if the front end of the traditional transparent cap is exposed too much, part of visual field can be blocked, so that the contact surface between the fixing sleeve and the front end of the endoscope is reduced, the transparent cap is easily separated into the intestinal cavity due to the loose fixing, and the safety of a patient is influenced;

4. the traditional transparent caps are straight pipes, are hard in material and cannot be elastically bent, and the compliance of the traditional transparent caps with the front end of the bendable endoscope is reduced;

5. the front end of the traditional endoscope or the transparent cap often clings to mucous membrane when the endoscope is taken in at difficult parts, particularly at the angle of a folding knife, so that a better visual field or even no visual field can be provided for an endoscope user, the trend of an intestinal cavity can not be distinguished, and the blind sliding mirror easily scratches the intestinal wall and even causes intestinal perforation.

Example 1

As shown in fig. 1, a drum-type endoscope transparent cap includes N drum-shaped protrusions 2 and n+1 straight tube sections 1, the straight tube sections 1 and the drum-shaped protrusions 2 are distributed at intervals in the length direction, and in this embodiment, there are 3 drum- shaped protrusions 2 and 4 straight tube sections 1. The wall thickness of the bulge 2 is equal to that of the straight tube section 1, the two ends of the bulge 2 are smoothly connected with the wall of the straight tube section 1, and the groove 4 formed between the straight tube section 1 and the bulge 2 can be better matched with the fold, so that the wheel-shaped fold is less prone to slipping off, the back surface and the rear view of the fold are well exposed, and more space is provided for an operator. The straight tube section 1 and the bulge 2 are integrally made of medical elastic silica gel, and the optimal distance between the groove 4 is determined according to the distance between the annular fold and the target area, so that transparent caps with different sizes can be manufactured, and the stepless distance adjusting effect is achieved. The outer diameter of the drum-shaped bulge 2 is preferably larger than the outer diameter of the straight pipe section 1 by about 6mm, and the front end of the transparent cap can be designed into a flat port, an inclined port or a conical shape and the like according to the needs so as to adapt to different scenes and requirements. The joint of the bulge 2 at the outermost end and the straight pipe section 1 is in gentle slope smooth transition, so that the lens can advance and retreat conveniently.

When the endoscope is used, the front end of the endoscope is inserted, the annular fold can be placed in the groove 4 between the two bulge-shaped bulges 2 at a harder part, then the endoscope body is slightly pulled backwards (in the external direction of the anus) while the front end of the endoscope is pressed down, the back surface and the rear visual field of the fold can be easily exposed, and because the groove 4 plays a relatively fixed role on the annular fold of the intestinal tract, an operator is not easy to slip when the endoscope body is slightly pulled backwards (in the external direction of the anus), so that the endoscope body is stabilized, and the operability of the endoscope is improved.

In all embodiments, the inner diameter of the straight pipe section 1 is slightly smaller than the outer diameter of the front end of the endoscope, and the characteristic that the diameter of the pipe can be elastically increased is adopted, so that the pipe can be smoothly assembled and taken out, and the pipe is tightly fixed at the front end of the endoscope by utilizing the elastic action without slipping.

In all embodiments, the side wall of the straight pipe section 1 at the front end of the transparent cap is provided with a drain hole 3. Preferably, the number of the drainage holes 3 is two, and the drainage holes are symmetrically arranged along the axis of the straight pipe section 1, so that accumulated water is conveniently discharged, and the influence of accumulated water on the field of view and definition of the endoscope is avoided.

Example two

As shown in fig. 2, one difference from the embodiment is that: the drum-shaped bulges 2 and the straight pipe sections 1 are spirally and alternately distributed along the length direction. Because the intestinal canal annular fold often moves like a semi-spiral, the spiral groove 4 can be better matched with the intestinal canal annular fold, and the optimal contact position with the groove 4 is determined according to the distance between the annular fold and a target area, so that the annular fold is less prone to slipping, the back and rear vision of the annular fold are well exposed, more space is provided for an operator, and the stepless distance adjusting effect is achieved.

Preferably, the inner wall of the transparent cap is a frosted surface, the direct light source is scattered, and when the frosted non-reflective end is used, the light source of the endoscope is not reflected, so that an image observed through the endoscope is clearer; the inner wall of the transparent cap is a frosted surface, so that friction between the inner wall of the transparent cap and the front end of the endoscope can be increased, the transparent cap is firmly fixed, and the transparent cap is not easy to slip; the outer wall of the transparent cap is coated with a hydrophilic material coating, so that the friction force of the outer surface is reduced after the transparent cap is contacted with water, and the transparent cap is smooth to use.

Of course, the present utility model is capable of other various embodiments and its several details are capable of modification and variation in light of the present utility model by one skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
