Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a small intestinal endoscope blocking device. Background Art

[0002] At present, the balloon-assisted enteroscope is used in my country. When performing related enteroscope operations or surgeries, the purpose of inserting the scope is generally achieved through the cooperation between the external outer sleeve and the scope body. During the operation, the outer sleeve is first placed in the corresponding position, and the airbag at the front end of the sleeve is inflated to fix the intestinal cavity. At the same time, the enteroscope body and the sleeve are pulled back to shorten the intestinal cavity, straighten the scope body, and put the free small intestine on the sleeve, and repeat the cycle. The main purpose of the outer sleeve is to shorten the small intestine, facilitate the in-depth insertion of the small intestine scope body, and then further exploration or surgery.

[0003] However, during the operation, due to the continuous bending and changes of the intestine, medical staff need to constantly extend and retract the sleeve or change the position to insert the endoscope. However, during the operation, there is a lot of friction between the outer sleeve and the small intestinal endoscope body, which will make the operation very inconvenient. In order to solve this technical problem, the commonly used method is now: inject relevant lubricants such as lubricating liquid, lubricating oil, etc. into the gap between the outer sleeve and the endoscope body; reduce the friction generated during the operation by adding lubricants. This method solves the above technical problems to a certain extent.

[0004] However, there are still some problems. For example, due to the existence of the gap, after adding the corresponding lubricant, as the operation proceeds, the lubricant will gradually flow out from the gap between the outer sleeve and the mirror body, thereby losing the lubricating effect. In order to ensure the lubricating effect, medical staff need to continuously increase the injection of new lubricant, which requires medical staff to operate frequently. There are still defects to a certain extent.

[0005] Therefore, in order to solve the above technical problems, a small intestinal endoscope occlusion device is needed. Summary of the invention

[0006] In order to solve the above technical problems, the present invention designs a small enteroscope blocking device, comprising: an outer sleeve, a small enteroscope, a blocking mechanism, and an inner blocking ring; the inner blocking ring is fixedly installed on the inner wall of the outer sleeve or the blocking mechanism is detachably installed on the end surface of the inner wall; the small enteroscope passes through the inner blocking ring or the blocking mechanism;

[0007] The blocking mechanism comprises a semi-blocking ring and a blocking block; the semi-blocking ring is an open-loop circular ring mechanism, a slide groove is provided on the side wall of the open-loop position of the semi-blocking ring, and a fixed collar is extended on one end face of the semi-blocking ring; the slider is an arc-shaped mechanism, and a plurality of sliders are provided on the two side walls of the slider, and the slider can be slidably installed on the slide groove; a fixed collar is also provided on one end face of the slider, and an injection tube is fixedly installed on the middle part of the upper end of the slider; the gap between the outer sleeve and the body of the small intestine endoscope is blocked by the blocking ring, and lubricating fluid is added through the provided injection tube;

[0008] Furthermore, the inner sealing ring is fixedly installed on the inner side wall of the outer sleeve near the end surface;

[0009] Furthermore, the blocking mechanism is installed on the end surface of the outer sleeve and between the gap of the small enteroscope body;

[0010] Furthermore, the inner sealing ring is fixedly installed on one end of the inner side of the outer sleeve, and the sealing mechanism is fixedly installed on the gap between the other end and the body of the small enteroscope;

[0011] Furthermore, a blocking layer is fixedly mounted on one end of the outer wall of the semi-blocking ring close to the fixed collar, and the diameter of the blocking layer increases linearly from the end away from the fixed collar to the end close to the fixed collar;

[0012] Furthermore, the structure of the inner blocking ring is a planar blocking ring (planar blocking structure);

[0013] Furthermore, the structure of the inner sealing ring is a bevel sealing ring (bevel sealing structure);

[0014] Furthermore, the structure of the inner sealing ring is a conical sealing ring (conical sealing structure).

[0015] The beneficial effects of the present invention are:

[0016] The present invention provides a small enteroscope blocking device, comprising: an outer sleeve, a small enteroscope, a blocking mechanism, and an inner blocking ring; the inner blocking ring is fixedly installed on the inner wall of the outer sleeve, or the blocking mechanism is detachably installed at the end surface of the inner wall; the small enteroscope body passes through the inner blocking ring or the blocking mechanism; the gap between the outer sleeve and the enteroscope body can be blocked by the provided blocking mechanism; that is, after blocking, corresponding lubricating liquid can be added for lubrication, so as to reduce the friction between the outer sleeve and the mirror body; at the same time, the blocking mechanism is in a detachable form, and can be installed between the gap between the outer sleeve and the mirror body by a detachable installation method, and an injection tube is provided on the blocking block of the blocking mechanism, and lubricating liquid can be further added through the injection tube so that the lubrication effect can be continuously produced.

[0017] In addition, the internal lubricating liquid can also be sealed by the inner sealing ring; the sealing mechanism and the inner sealing ring can be used together or separately; one is external and the other is internal, which can be selected according to actual needs; compared with the traditional treatment method, the device can lock the lubricant in the gap, which can greatly ensure the lubrication effect and reduce the friction between the outer sleeve and the mirror body gap. At the same time, the injection tube can also be added, and the lubricant can be added quickly through pipeline injection, which is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] A lubricant blocking device for a small enteroscope 2, comprising: an outer sleeve 1, a small enteroscope 2, a blocking mechanism 3, and an inner blocking ring 4; the inner blocking ring 4 is fixedly mounted on the inner side wall of the outer sleeve 1, or the blocking mechanism 3 is detachably mounted on the end surface of the inner side wall; the small enteroscope 2 passes through the inner blocking ring 4 or the blocking mechanism 3; the blocking mechanism 3 is provided to block the gap between the outer sleeve 1 and the small enteroscope 2; that is, after blocking, a corresponding lubricant can be added for lubrication, so as to reduce the friction between the outer sleeve 1 and the body 2 of the small enteroscope;

[0030] The blocking mechanism 3 includes a semi-blocking ring 31 and a blocking block 32; the semi-blocking ring 31 is an open-loop circular ring mechanism, and a slide groove 313 is provided on the side wall of the open-loop position of the semi-blocking ring 31, and a fixed collar 312 is extended on one end face of the semi-blocking ring 31; the slider 322 is an arc-shaped mechanism, and a plurality of sliders 322 are provided on the two side walls of the slider 322, and the slider 322 can be slidably installed on the slide groove 313; a fixed collar 312 is also provided on one end face of the slider 322, and the upper end of the slider 322 An injection tube 321 is fixedly installed in the middle; the gap between the outer sleeve 1 and the small enteroscope 2 is blocked by a sealing ring, and lubricating fluid is added through the set injection tube 321; specifically, when in use, first, after the outer sleeve 1 is fixed, the small enteroscope 2 is directly inserted into the outer sleeve 1, and then the semi-sealing ring 31 is inserted through the small enteroscope 2, and after it is stuck, the slider 322 on the blocking block 32 is aligned with the slide groove 313 and slides directly into it, and after sliding in, the entire blocking mechanism 3 is directly inserted into the gap between the outer sleeve 1 and the small enteroscope 2 to complete the blocking.

[0031] At the same time, in order to ensure the sealing performance after the plugging mechanism 3 is inserted, a plugging layer 311 is fixedly installed on the end of the outer wall of the semi-blocking ring 31 close to the fixed collar 312, and the diameter of the plugging layer 311 increases linearly from the end away from the fixed collar 312 to the end close to the fixed collar 312; and the plugging layer 311 can be made of rubber or silicone material, which can greatly ensure the sealing performance while increasing the friction. The injection tube 321 provided at the same time can also be added, and the lubricant can be added quickly by pipe injection.

[0032] Example 2

[0033] Based on the existence of the inner sealing ring 4 and the sealing mechanism 3 described in Example 1, this embodiment further explains them. Specifically, the inner side wall of the outer sleeve 1 is fixedly installed with the inner sealing ring 4 near the end face; that is, the sealing mechanism 3 is not required at this time, and the inner sealing ring 4 is directly installed on both ends of the inner side wall of the outer sleeve 1. The internal lubricant is directly blocked to a certain extent by the inner sealing ring 4. This blocking method does not require additional devices for blocking and directly uses a simple inner sealing ring 4 for blocking; it is equivalent to changing the diameter of the outer outer sleeve 1 so that the outer sleeve 1 and the small enteroscope 2 fit more tightly. In this way, the internal lubricant is locked to change the friction generated by the entire outer sleeve 1 to only two inner sealing rings 4 with smaller widths, which is equivalent to extremely reducing the friction. While achieving lubrication, it also greatly reduces the generation of friction; however, when using this method, if lubricating fluid needs to be added, it needs to be added after the small enteroscope 2 is taken out.

[0034] In addition, in the present embodiment, the blocking mechanism 3 is installed on the end surface of the outer sleeve 1 and between the gap of the small enteroscope 2; specifically, both ends of the blocking mechanism 3 are installed on the two end surfaces of the outer sleeve 1, and blocking is performed by the blocking mechanism 3 at the same time. This method does not need to change the internal structure of the outer sleeve 1 itself, and can add lubricant from the outside. While being able to block, the lubricant can be added at any time according to actual needs. However, the device requires the doctor to install the blocking mechanism 3 from both sides, and if the blocking mechanism 3 is installed on one side, the problem that needs to be considered is that after the outer sleeve 1 is inserted during use, the blocking mechanism 3 may slip or damage the relevant parts of the patient during the removal process, which is a defect to a certain extent, equivalent to the coexistence of advantages and disadvantages.

[0035] In addition, in the present embodiment, the inner sealing ring 4 is fixedly installed on one end of the inner side of the outer sleeve 1, and the sealing mechanism 3 is fixedly installed on the gap between the other end face and the small intestine endoscope 2; specifically, the inner side of the outer sleeve 1 is provided with an inner sealing ring 4, and the other end is not provided with a sealing ring but is sealed by the sealing mechanism 3; in this way, the internal sealing built into the front end allows the outer sleeve 1 to be used normally without worrying about slipping and damaging the relevant parts of the patient, and at the same time, the detachable sealing mechanism 3 at the rear end and the injection tube 321 provided on the sealing block 32 can add lubricant at any time; this method not only solves the problem that the sealing mechanism 3 may slip or damage the relevant parts of the patient when used alone, but also effectively solves the problem of adding lubricant; therefore, this method is a better method when used.

[0036] Example 3

[0037] Based on the inner sealing ring 4 described in Example 2, in this embodiment, its specific structural features are further elaborated; specifically, the structure of the inner sealing ring 4 is a plane sealing ring 41 (plane sealing structure) or the structure of the inner sealing ring 4 is a sloped sealing ring 42 (slope sealing structure); or the structure of the inner sealing ring 4 is a conical sealing ring 43 (conical sealing structure).

[0038] When the structure of the inner sealing ring 4 is a planar structure, specifically as follows Figure 5 As shown, it can effectively form a blockage; however, the plane structure means that the friction it can bring is relatively large. Although compared with the outer sleeve 1 without the inner blocking ring 4, the structure can greatly reduce the problem of friction; but it still has friction during use, so it can be further improved. As we all know, friction is related to the friction coefficient of the plane and the relative contact area. Therefore, according to this principle, the friction plane is now reduced, and the structure of the inner blocking ring 4 is changed to a bevel blocking structure, as shown in the following figure. Figure 6 As shown, this structure can greatly reduce the friction force. Compared with the plane structure, it can convert the plane contact into the line contact, which can well solve the above technical problems. However, it still has a small defect that when the small enteroscope 2 is taken out, the inner sealing ring 4 with a non-bevel structure on one side is not convenient for taking out the small enteroscope 2; at the same time, the surface of the small enteroscope 2 may be scratched. In order to solve the above technical problems, in this embodiment, the bevel structure is changed to a conical structure, that is, a double bevel structure, such as Figure 7 As shown, this method can prevent the surface of the small intestine endoscope 2 from being scratched, and can also greatly reduce friction. Relatively speaking, it is better than the inclined structure and the plane structure. The conical structure is a better choice for the inner sealing ring 4.
