Description

Self-cleaning endoscope with self-priming function

technical field

The utility model relates to a medical instrument, in particular to an endoscope with an improved object lens.

Background technique

During the use of the endoscope, the objective lens is often blurred due to liquid contamination, which affects the visual effect. A self-cleaning endoscope provided with a nozzle is described in the existing literature, which can be washed with water after the lens is polluted. However, this structure tends to leave effusions at the corners of the lens. Even if it has an active water absorption device, due to its structural defects, the effusions at the corners are still difficult to absorb.

Contents of the invention

The technical problem to be solved by the utility model is to provide a self-cleaning endoscope with a self-suction function to remove fluid accumulation on the clean lens.

The technical solution of the utility model is: it includes an objective lens, and the outer edge of the ring lens of the objective lens is provided with an absorbing device composed of a ring-shaped water-absorbing ring, a support net and an absorbing cotton sliver, and the water-absorbing ring has a water-absorbing hole on the inner side The tubular body or the annular body with a "C"-shaped cross-section of the inner opening, the water-absorbing ring is connected to the negative pressure liquid suction device through the pipeline, the support net is covered on the inner side of the water-absorbing ring, the absorbent cotton sliver is placed inside the support net, and the absorbent cotton The strip is in contact with the edge of the lens of the objective lens, and the end of the objective lens is screwed with an annular gland to clamp the water-absorbing ring, the support net and the absorbent cotton sliver.

The technical effect of the utility model is: it has the advantages of simple and reasonable structure, convenient use and thorough cleaning, can quickly absorb the washing liquid at the lens at any time, keep the objective lens clear, and prevent the residual liquid of the eye lens from deforming the visual object and affecting imaging Effect.

Detailed ways

As shown in Figures 1, 2 and 3, it includes an objective lens 1, and the outer edge of the ring lens 2 of the objective lens 1 is provided with an absorbing device composed of an annular water-absorbing ring 3, a support net 4 and an absorbent cotton sliver 5, The water-absorbing ring 3 is a tubular body with water-absorbing holes on the inside or a ring body with a "C"-shaped cross-section of the inner opening. The water-absorbing ring 3 is connected to the negative pressure liquid suction device through a pipeline. The cotton sliver 5 is placed inside the support net 4, and the absorbent cotton sliver 5 is in contact with the edge of the lens 2 of the object lens 1, and the end of the object lens 1 is screwed with an annular gland 6 to connect the water-absorbing ring 3, the support net 4 and the absorbent cotton Strip 5 is clamped. The pressing cover 6 can adjust the degree of compression to the adsorption cotton sliver 5, so as to adjust the adsorption effect.

The negative pressure liquid suction device is composed of an inner cylinder 7, an outer cylinder 8, a retaining ring 9 and a spring 10. The inner cylinder 7 and the outer cylinder 8 are cylinders with open upper and lower ends respectively, and the open end of the inner cylinder 7 is The outer edge is provided with a piston part 11, and the top of the outer cylinder 8 is provided with an air suction pipe 12 and an exhaust pipe 13 connected with a one-way valve. 11, the inner diameter of the retaining ring 9 is smaller than the outer diameter of the piston part 11 of the inner cylinder 7, the retaining ring 9 is sleeved on the inner cylinder 7 and screwed to the lower end of the outer cylinder 8, the spring 10 is placed in the inner cylinder 7 and the outer cylinder 8 and the two The ends respectively abut against the end walls of the inner cylinder 7 and the outer cylinder 8. Suction pipe 12 is connected with suction ring 3 by pipeline.

The utility model has a reasonable structural design, and the water-absorbing ring, the support net and the absorbent sliver can be replaced after use, and the absorbent sliver can be made of any hygienic material with adsorption and permeability, such as absorbent cotton. During the adsorption process, the liquid will gradually gather towards the corners, therefore, the liquid on the surface of the lens can be completely removed by absorbing the tampon. The negative pressure liquid suction device has a simple structure and is easy to clean.
