In order that the above-described aspects may be better understood, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

In recent years, the rapid development of digestive endoscopy technology provides more updated diagnosis and treatment methods in the aspect of disease diagnosis of digestive tracts and related organs, and particularly, the popularization and application of ultrasonic endoscopy technology plays a great role in the aspect of diagnosis and treatment of digestive tract tumors and early lesions thereof.

At present, the ultrasonic endoscopes commonly used in clinic have 2 types of ultrasonic endoscopes, namely small probe ultrasonic endoscopes and longitudinal shaft ultrasonic endoscopes, the 2 types of ultrasonic endoscopes have the advantages, the ultrasonic endoscopes are not suitable for routine examination due to the high price of the ultrasonic endoscopes, the longitudinal shaft ultrasonic endoscopes have the ultrasonic probes at the front end of an insertion tube, the examination process is painful, many medical institutions do not develop routine daily, cases are generally found during gastrointestinal endoscopy, and a patient needs to reserve special time for the ultrasonic endoscopes.

The gastrointestinal endoscopy is carried out to find more submucosal protrusions of the digestive tract, an endoscope operator needs to carry out preliminary judgment on the focus of the submucosal protrusions by means of an endoscope accessory, the external pressure of viscera or the digestive tract swelling is considered, the size and the texture of the protrusions are estimated, no special accessory is clinically available at present, the endoscope operator is generally replaced by an endoscope biopsy forceps, and the following defects exist in the use of the endoscope biopsy forceps:

1. easily causes damage and bleeding of digestive tract mucosa: the biopsy forceps are made of stainless steel, hard, sharp in biopsy forceps valve and vulnerable to damage and hemorrhage of mucous membrane caused by damage to mucous membrane surface of digestive tract when the origin and the texture of the focus are judged by palpation;

2. the lesion size cannot be accurately assessed: the size of the submucosal bulge of the alimentary canal is variable, the opening of the forceps valve of the endoscope biopsy forceps is generally 6-8mm, the size can be estimated only through the endoscope image, the magnification of the endoscope image or a display is different, and the fluctuation of the estimated range is large;

3. increasing inspection costs: the function of the endoscope biopsy forceps is to clamp mucous membrane tissues for pathological examination, and most of the forceps are disposable, for example, the digestive tract of a patient does not have pathological changes and does not need biopsy, so that the endoscope biopsy forceps are used for the above operation, waste is generated, and the examination cost of the patient is increased.

Fig. 1 to 3 are views showing an apparatus for measuring a submucosal lesion of a digestive tract according to an embodiment of the utility model, including:

an outer sleeve pipe: a hollow, the inside of which forms a channel for sliding the inner core 3; the outer sleeve comprises a clamping section 1 and an inserting section 2, wherein the clamping section 1 consists of two baffle plates 11 which are coaxially arranged, and a ring groove 12 for clamping fingers is formed between the two baffle plates 11; the insertion section 2 consists of two parallel pipelines with an 8-shaped cross section; optionally, the clamping section 1 is made of PVE medical material, and the inserting section 2 is made of stainless steel material. The outside maximum size of this measuring device insert section 2 does not exceed 2.6mm to the biopsy forceps pipeline through the scope is convenient, for convenient washing, still is provided with cleaning element 21, can see from fig. 2 that cleaning element 21 interconnects with the inner chamber of insert section, and from outside filling washing liquid, washing liquid fills whole inner chamber, flows out from the opening part of insert section 2, realizes sterile effect, of course, cleaning element 21 sets up can be a passageway corresponds one, also can only set up one.

And an inner core 3: two bent metal wires are respectively arranged in the pipeline; since the wire is already pre-bent and is constrained by the surrounding material in the insertion section 2, and when it extends out of the insertion section 2, it will resume its bent state and open, and this structure can be used for many times, the wire can maintain its pre-made shape for a long time without being subjected to high temperature annealing, so that it can ensure the constant physical quantity measured. Two inner cores 3 are combined to form a combined section 31 near one end of the clamping section 1, and scales 5 are arranged on the combined section 31; optionally, the scale 5 comprises two sets: one group is the extension length of the inner core 3, which is an absolute value, and the other group is the opening length of the marking element 32, which are calibrated during the manufacture of the measuring device, and are mutually referenced, so that the numerical effectiveness of the measuring device during the service life can be ensured.

The tail end of the merging section 31 is provided with a lantern ring 4 for a finger to pass through; the other end of the core 3 extends out of the channel and is bent to form the marking element 32. Alternatively, the marking element 32 is in the form of a circular sheet. Further, the marking element 32 is integrally formed with the inner core 3, and is designed in a circular sheet shape in order to avoid scratching the mucosa of the digestive tract, and may be further finely polished, and the integrally formed part may be processed by punching or the like. Optionally, a sealing rubber sleeve (not shown in the figure) is arranged between the clamping section 1 and the lantern ring 4, the sealing rubber sleeve is made of transparent materials, and the purpose of the rubber sleeve is to prevent body fluid from being carried out of the pipeline by the inner core 3 to pollute an operation area due to capillary phenomenon during inspection, and the device is used in a specific inspection environment.

The inner core 3 is arranged in the sleeve, two fingers extend into the annular groove 12 to clamp the clamping section 1, the other finger extends into the lantern ring 4, the inner core 3 is driven to move in the sleeve by pushing and pulling the lantern ring 4, the marking element 32 is opened and closed, and the scale 5 on the combining section 31 is matched to measure the size of the marker.

Figure 4 shows that the overlapping of the marker elements 32 prevents the core 3 from being pulled out of the tube when the core is retracted, and also allows the tip of the insertion section 2 to be sized so as not to exceed the maximum allowable size of the endoscope passageway.
