Description

Biopsy pore canal attached water delivery converter

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a biopsy orifice auxiliary water delivery converter.

Background

The digestive endoscopy examination and treatment have the advantages of simple operation, small damage, quick recovery of patients and the like, and are more and more valued by medical workers; with the development of digestive endoscopy technology in recent years, the digestive endoscopy is not limited to symptomatic examination and simple endoscopic treatment, but is used for diagnosing early change of digestive tract mucosa (early cancer) and performing endoscopic early cancer mucosa stripping treatment (killing malignant lesion in early stage), and has the advantages of early discovery, early treatment and small wound surface and quick recovery.

In actual work, digestive endoscopes have problems in use, such as: 1. the digestive tract sometimes has undiluted stool and thick intestinal fluid to influence the observation; 2. the emergency endoscope which does not prepare for the intestinal tract for the gastrointestinal hemorrhage with unknown reasons is extremely difficult to find the reason of the hemorrhage due to the large amount of blood in the gastrointestinal tract; 3. some imported products in the market are disposable, so that the parts are more, more and more, can be complicated, have high cost, and are easy to break and not durable.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present invention discloses a biopsy channel-attached water converter.

The purpose of the utility model is realized by the following technical scheme:

a biopsy well-attached water transducer, wherein: the biopsy pore canal attached water supply converter comprises a plastic tee joint and a hollow metal pipe;

the port I of the plastic tee is matched with the biopsy cap; the port II is matched with the auxiliary water supply device;

one end of the hollow metal tube is inserted into a port III of the plastic tee joint and connected with the plastic tee joint, and the other end of the hollow metal tube is connected with a biopsy channel cap and inserted into a biopsy channel of the digestive endoscope; the outside of the hollow metal tube is provided with a baffle ring.

The biopsy pore canal of the technical scheme is provided with a water supply converter, wherein: the port II and the hollow metal pipe form an L-shaped water path.

The biopsy pore canal of the technical scheme is provided with a water supply converter, wherein: the plastic tee joint is integrally formed.

The utility model has the following beneficial effects:

1. the application of the product can improve the detection rate of pathological changes, wash the wound surface of a pathological change part in treatment, effectively help to observe the field of vision of the treated wound surface and better continue the treatment.

2. When the digestive tract has defecate which is not discharged and thick intestinal juice which affect the observation, the converter of the utility model is externally connected with the water delivery device, the converter can be used for washing under the endoscope in the digestive endoscopy and the treatment, the sundries which affect the observation are washed away, and the clear visual field of the digestive endoscopy and the operation or observation effect are ensured.

3. The emergency endoscope which is used for treating the gastrointestinal hemorrhage without intestinal preparation is extremely difficult to find the reason of the hemorrhage due to a large amount of blood in the gastrointestinal tract, and can quickly find out the pathological changes for treatment by flushing the intestinal cavity by the attached water delivery device.

4. The utility model has simple structure, easy use and low cost; except the plastic tee joint, the other parts are externally connected, so the maintenance cost is low; the product can be used by repeated disinfection, and the cost is further reduced.

5. The water injection enteroscope combining the biopsy pore passage with the water delivery converter and the enteroscope can not only wash dirty enteroscope, but also fix the enteroscope through the gravity of water, thereby better entering the enteroscope, reducing gas injection and relieving abdominal distension and abdominal pain.

2. Fig. 2 is a cross-sectional view of a biopsy channel with attached water transducer.

3. Fig. 3 is a schematic view of two passages of a biopsy channel with water transfer.

Description of the figure numbers:

1. plastic tee joint 11, ports I and 12, ports II and 13 and port III; 2. a hollow metal tube 21, a baffle ring 22, one end of the hollow metal tube 23 and the other end of the hollow metal tube.

The specific implementation mode is as follows:

in order to facilitate understanding of the technical solutions of the present invention, the following structures and applications of the present invention are further described with reference to the specific embodiments and the accompanying drawings.

Example 1:a biopsy well-attached water transducer:

a biopsy channel attached water converter as shown in fig. 1 and 2, comprising an integrally formed plastic tee 1 and hollow metal tube 2;

a port I11 of the plastic tee is matched with the biopsy cap; the port II 12 (water inlet) is matched with the auxiliary water supply device;

one end 22 of the hollow metal tube 2 is inserted into a port III 13 of the plastic tee joint 1 to be connected with the plastic tee joint 1, and the other end 23 of the hollow metal tube is connected with a biopsy channel cap and is inserted into a biopsy channel of the digestive endoscope; a baffle ring is arranged outside the hollow metal tube;

as shown in fig. 3, two passages are formed in the biopsy channel water-feeding converter, the passage is an L-shaped waterway formed by the port ii 12 and the hollow metal tube 2, and the passage is a linear therapeutic instrument passage formed by the port i 11 and the hollow metal tube 2.
