Description

Intermediate adapter applied to endoscope and endoscope

Technical Field

The utility model belongs to the technical field of endoscopes, and relates to an intermediate adapter applied to an endoscope and the endoscope.

Background

An endoscope is a commonly used medical instrument, and an imaging module is disposed at the front end of an insertion portion thereof, so that the endoscope has a visualization function. The tube-placing mirror belongs to another use of the endoscope, and aims to quickly insert an placing tube which needs to be placed into a human body to a target position.

In the prior art, the imbedding tube is a tube body with certain deflection, two ends are provided with openings, one end of the imbedding tube is imbedded in a target position of a human body, and the other end of the imbedding tube is arranged outside the body, so that medical staff can conveniently directly inject fluid into the human body from a port positioned at the outer side of the imbedding tube, or the target position inside the human body is pumped by connecting negative pressure equipment so as to achieve the expected treatment purpose; however, for a complex internal environment of a human body, especially in a process of entering a deeper target position in the human body through a natural cavity of the human body, since the implantation tube itself does not have active bending and visualization functions, on one hand, an operator needs to rely on a lot of clinical experience, and meanwhile, a corresponding imaging device such as a CT machine needs to be equipped around a patient to assist the operator in performing an implantation operation of the implantation tube until the implantation tube is inserted into the target position, the process is long, usually requires 1-2 hours, and meanwhile, steering is achieved by abutting against a wall surface of the cavity of the human body during the insertion of the implantation tube, so that internal tissues of the human body are easily scratched.

For the imbedding pipes with different specifications, the imbedding pipes can be smoothly imbedded only by adapting to the imbedding pipes with different sizes; therefore, hospitals are required to purchase a variety of sizes of catheterization lenses. For the specification of the insertion tube with lower use frequency, the use frequency of the matched insertion tube mirror is low, and idle waste is caused.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances. Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.

In the present utility model, unless expressly stated or limited otherwise, a first feature may include first and second features directly contacting each other, either above or below a second feature, or through additional features contacting each other, rather than directly contacting each other. Moreover, the first feature being above, over, and on the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being below, beneath, and beneath the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is less level than the second feature.

In addition, in the utility model, the 'near end' and the 'far end' are far and near positions of the structure relative to human body operation under the use environment, so that the description of the position relationship among the components is convenient, and meanwhile, the understanding is convenient; for the same component, "proximal" and "distal" are relative positional relationships of the component, not absolute; accordingly, it should be understood from the perspective of implementing the principles of the present utility model without departing from the spirit of the utility model.

Generally, different sizes of the insertion tube 20 are generally applied to different human body lumens, for larger lumen sizes, a large size of the insertion tube 20 can be used, and for smaller lumen sizes, only a small size of the insertion tube 20 can be used; referring to fig. 1 and 2, when the endoscope and the insertion tube 20 are assembled, the insertion portion 30 of the endoscope is inserted into the lumen 200 of the insertion tube 20 along the direction S until the distal end of the endoscope is inserted into the distal end of the insertion tube 20 and protrudes from the opening 21. Referring to fig. 1-8, when an operator actuates a thumb lever or thumb wheel of the endoscope to bend the active bending section 32 of the insertion portion 30 in a predetermined direction, the insertion tube 20 disposed outside of the endoscope insertion portion 30 is forced to bend in a predetermined direction together. It is found through analysis that when the outer ring size of the insertion portion 30 of the tube endoscope is smaller and the specification of the insertion tube 20 to be inserted is larger, such as shown in fig. 2, a gap a exists between the outer periphery of the insertion portion 30 and the inner wall 22 of the insertion tube 20, when the active bending section 32 of the insertion portion 30 is driven to bend, the active bending section 32 is firstly bent in the inner ring space of the insertion tube 20 until the outer side of the active bending section 32 can abut against the inner wall 22 of the insertion tube 20 after being bent to a certain extent, and the larger the gap a is, the active bending section 32 needs to bend by a larger angle before abutting against the inner wall 22 of the insertion tube 20, so that the insertion tube 20 can be forced to bend only after the active bending section 32 is driven to bend further; meanwhile, due to the gap, the bending angle of the active bending section 32 to overcome the gap is wasted, so that the implantation tube 20 cannot be bent to the same angle along with the active bending section 32 after being bent to the maximum bending angle, and thus the bending range of the implantation tube 20 is limited, and the implantation process of the implantation tube 20 is affected.

Therefore, through the above analysis, the present utility model proposes that the insertion requirements of the insertion tube 20 with different specifications are satisfied only by the insertion tube lens with one specification, and the deflection angle of the insertion tube 20 is not affected.

Referring to fig. 3, an intermediate adapter 10 for an endoscope includes:

a flexible pipe body 13, wherein an elastic support body 11 is arranged on the periphery of the flexible pipe body 13, and the elastic support body 11 can be compressed along the radial direction of the flexible pipe body 13; the flexible tube is configured to be mounted on the periphery of the active bending section 32 of the endoscope, and the elastic support 11 is configured to fill a gap between the active bending section 32 and the inner wall 22 of the insertion tube 20, and further, the elastic support 11 abuts against the inner wall 22 of the insertion tube, as shown in fig. 4. It should be noted that, the elastic supporting body 11 may be made of a material such as silica gel or rubber, and may be deformed under the action of external force, and the deformation is used to be tightly filled into the inner wall 22 of the insertion tube 20 and the outside of the insertion portion 30, so that the gap a shown in fig. 2 is eliminated; therefore, when the operator drives the active bending section 32 to bend, the elastic supporting body 11 is supported at the proximal end and the distal end of the active bending section 32, and the bending angle loss caused by the gap a is not needed to be overcome in the bending process, namely, the active bending section 32 bends, the implantation tube 20 which is adapted to the outer side of the active bending section 32 of the implantation tube mirror bends synchronously and at the same angle, so that the problem of limited bending range of the implantation tube 20 is solved.

In an alternative embodiment of the present utility model, the intermediate adaptor 10 may be two ring bodies having elastic supporting bodies 11 on the outer sides, and respectively sleeved on the proximal end and the distal end of the active bending section 32 of the insertion portion 30. Alternatively, the elastic support 11 of the intermediate adapter 10 is entirely covered on the outside of the flexible tube 13, as shown in fig. 5. In the embodiment shown in fig. 5, the elastic support body 11 is provided with spiral protrusions 14 at the outer circumference, and the height between the top of each spiral protrusion 14 and the bottom of the groove formed between the two spiral protrusions 14 can be adapted to the matching between the insertion part 30 of the endoscope and the insertion tube 20 of different specifications.

In other alternative embodiments, the elastic support body 11 is disposed at least in the distal circumferential direction of the flexible tube body 13, and in the proximal circumferential direction of the flexible tube body 13; and the spacing between the two elastic supports 11 disposed in the distal and proximal circumferential directions is adapted to the length of the active bending section 32, as shown in fig. 4 and 6. Further, as shown in fig. 7, if the length of the active bending section 32 is b, the length of the intermediate adaptor 10 can be set to be matched with the length of the active bending section 32, so that the bending force can be directly exerted on the intermediate adaptor 10 by the distal end and the proximal end of the active bending section 32 during the bending process of the active bending section 32, and the force can be transmitted to the insertion tube 20 through the intermediate adaptor 10.

Referring to fig. 3, in a preferred embodiment, the elastic supporting body 11 includes a protruding portion 11a and a recessed portion 11c extending in a radial direction thereof, and an outer circumferential dimension of the protruding portion 11a is larger than an outer circumferential dimension of the recessed portion 11 c; namely, the avoidance space of the elastic support body 11 is formed by the spacing c between the protruding portion 11a and the recessed portion 11c, specifically, c is not a specific value, and can be set according to practical needs, so as to meet the matching between the inner diameters of different implantation tubes 20 and the outer diameters of the insertion portions 30, in general, when the flexible tube body 13 is sleeved outside the insertion portions 30 and then inserted into the cavity 200 of the implantation tube 20, the outer ring diameter of the protruding portion 11a is greater than or equal to the inner diameter of the implantation tube 20, so that the protruding portion 11a will be avoided and retracted into the space of the recessed portion 11c in the radial direction, and the intermediate adapter 10 can be installed into the cavity 200 of the implantation tube 20; thereby improving the fit between the endoscope and the insertion tube 20. Further, the protruding portion 11a and the recessed portion 11c are provided at intervals in the axial direction of the flexible pipe body 13.

In other alternative embodiments, the elastic support body 11 is ring-shaped and is detachably mounted to the outer circumference of the flexible pipe body 13. That is, in this embodiment, the elastic support body 11 and the flexible tube body 13 are provided separately, and therefore, it is not required that the flexible tube body 13 and the elastic support body 11 are made of the same material.

After the intermediate adapter 10 is mounted to the gap between the insertion portion 30 and the insertion tube 20, the gap is filled and closed, so that the sealing performance is improved, and the insertion tube 20 is prevented from introducing tissue fluid and human tissue into the gap at the front end thereof during the insertion process.

The present utility model also provides an endoscope comprising the above-described intermediate adapter 10, said intermediate adapter 10 being removably mounted on the periphery of the active bending section 32 of said endoscope.

Referring to fig. 8 for the installation of the intermediate adapter 10, the intermediate adapter 10 is coaxially disposed with the insertion portion 30, and then the intermediate adapter 10 is installed from the distal end of the insertion portion 30 along the axis M of the lumen 100 in the direction indicated by f1 to the outside of the insertion portion 30, specifically to the outside of the active bending section 32 of the insertion portion 30, and then the insertion portion 30 is inserted from the proximal end opening 21 of the insertion tube 20 to the distal end of the insertion tube 20 in the direction indicated by f 2; and thus an operation of inserting the insertion tube 20 into the human body can be performed.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
