Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and more particularly to a protective cover for removing sharp foreign bodies from the upper digestive tract through endoscopy. Background Art

[0002] Foreign bodies in the upper gastrointestinal tract are common emergencies in gastroenterology. If the condition is serious, it can cause gastrointestinal perforation, bleeding, and concurrent infection, which can be life-threatening. Endoscopic removal of foreign bodies is the main method for treating foreign bodies in the upper gastrointestinal tract. However, it is still difficult to remove foreign bodies with sharp edges and large volumes, such as metal nails and blades. When the foreign body is removed through the esophagus by endoscopy, there is still a risk of secondary injuries such as perforation and bleeding.

[0003] In response to this, clinicians have developed various methods to try to physically wrap sharp foreign objects for safe removal, including the use of a transparent cap at the front end of the endoscope. However, due to the small space of the transparent cap, it is difficult to completely wrap larger foreign objects, which limits its use and needs to be improved. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a protective sleeve for endoscopic removal of sharp foreign bodies in the upper digestive tract with a larger wrapping space.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A protective sleeve for removing sharp foreign bodies from the upper digestive tract through endoscopy, comprising:

[0007] A fixed sleeve, the fixed sleeve is used to be sleeved on the front end of the endoscope, the front end of the fixed sleeve forms a mounting surface, the mounting surface is used to cover the water outlet to guide part of the water flow to move in the direction of the endoscope axis, the fixed sleeve is provided with a limit block corresponding to the mounting surface, when the fixed sleeve is sleeved on the endoscope, the mounting surface forms a gap with the front end of the endoscope through the limit block;

[0008] The flexible sleeve is trumpet-shaped, one end of the flexible sleeve is connected to the mounting surface, a protective space is formed inside the flexible sleeve, a support channel is provided on the flexible sleeve corresponding to the mounting surface, the support channel extends along the length direction of the flexible sleeve, one end of the support channel forms an opening corresponding to the mounting surface, and the opening is used for water flow to enter to keep the support channel in an open state.

[0009] As a further improvement of the present invention, an elastic shrink ring is provided at the opening corresponding to the support channel, and the shrink ring is used to open the opening under the impact of water flow.

[0010] As a further improvement of the present invention, the mounting surface includes a guiding surface and limiting surfaces arranged on both sides of the corresponding guiding surface. The guiding surface corresponds to the limiting block, and the gap is formed by the joint enclosure of the guiding surface, the limiting block, and the limiting surfaces, and a guiding opening is formed corresponding to the edge of the guiding surface. The guiding opening corresponds to the axis of the fixed sleeve.

[0011] As a further improvement of the present invention, the soft sleeve forms thick layers corresponding to both sides of the support channel, and the remaining positions are thin layers.

[0012] As a further improvement of the present invention, both the fixed sleeve and the soft sleeve are made of transparent materials.

[0013] As a further improvement of the present invention, guiding lines are provided on both sides of the soft sleeve corresponding to the thick layers.

[0014] As a further improvement of the present invention, an attaching band is provided at the rear end of the fixed sleeve, and the attaching band is used for adhering and fixing to the outer wall of the endoscope.

[0015] Advantages of the present invention:

[0016] 1. By adopting the soft sleeve, it can automatically deform to the end of the endoscope when the endoscope enters, so as to reduce interference with the entry of the endoscope. At the same time, it can naturally deform to the front end of the endoscope when clamping and withdrawing, so as to complete the wrapping of sharp foreign objects, thereby avoiding possible injuries caused by the removal of sharp foreign objects;

[0017] 2. The trumpet-shaped soft sleeve can obtain a larger protection space, thus ensuring the adaptability to foreign objects of larger volume;

[0018] 3. The setting of the support channel can be expanded through the water outlet carried by the endoscope itself. On the one hand, it can ensure the expansion of the soft sleeve, and the overall device is simple and compact. On the other hand, the method of using the mounting surface in cooperation with the limiting block can guide the water flow of the water outlet, thereby improving the cleaning effect of the image port position to obtain a better observation field of view.

Detailed implementation mode

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The same components are denoted by the same reference numerals.

[0025] Refer to Figure 1 , an endoscope in the prior art, which is tubular and is respectively provided with an instrument port 1, a light source port 2, an image port 3 and a water outlet 4 at the front end. Among them, the instrument port 1 is used for the instrument to extend in to complete the clamping action, the light source port 2 is used to provide light for the interior of the human body, and at the same time the image port 3 can collect clear images inside the human body. The water outlet 4 is used for cleaning the image port 3 on the one hand to reduce the interference caused by body fluids in the human body to the surgical field, and at the same time can also flush the interior of the human body to expose possible trauma points.

[0026] Among them, the arrangement of the instrument port 1, the light source port 2, the image port 3 and the water outlet 4 and the internal pipeline are the same as those in the prior art, and will not be elaborated here.

[0027] A protective sheath for removing sharp foreign bodies in the upper digestive tract through an endoscope according to this embodiment is applicable to the above-mentioned endoscope to provide protection when clamping sharp foreign bodies during the operation and avoid additional injuries caused by the foreign bodies when withdrawing from the human body.

[0028] Refer to Figures 1-4 , a protective sheath for removing sharp foreign bodies in the upper digestive tract through an endoscope, including a fixed sleeve 5. The fixed sleeve 5 is used for sleeving on the front end of the endoscope to complete the connection and fixation with the endoscope. An installation surface 6 is formed at the front end of the fixed sleeve 5. The installation surface 6 is used for covering the water outlet 4 to guide part of the water flow in the direction of the endoscope axis, thereby improving the cleaning effect of the water flow on the image port 3. In another way, the water flow can also be directly guided in the direction of the image port 3. Since the connection line between the image port 3 and the water outlet 4 does not pass through the endoscope axis, it is not easy for the operator to control the water flow direction in this type of setting, so as to flush the interior of the human body. By guiding the water flow to the endoscope axis, the operator can easily control the position of the water flow to better flush the human body.

[0029] Furthermore, in order to achieve the guiding effect, a limit block 7 is provided on the mounting surface 6 corresponding to the fixed sleeve 5. When the fixed sleeve 5 is sleeved with the endoscope, a gap 8 is formed between the mounting surface 6 and the front end of the endoscope through the limit block 7. The gap 8 can increase the impact force of the water outlet 4 to improve the cleaning effect on the image port 3.

[0030] Preferably, a soft cover 9 is included, and the soft cover 9 is trumpet-shaped, so that the soft cover 9 obtains a larger protection range. One end of the soft cover 9 is connected to the mounting surface 6, and the connection method is preferably bonding. A protection space 10 is formed in the soft cover 9. A support channel 11 is provided on the soft cover 9 corresponding to the mounting surface 6. The support channel 11 extends along the length direction of the soft cover 9. An opening 12 is formed at one end of the support channel 11 corresponding to the mounting surface 6. The opening 12 is used for water flow to enter to keep the support channel 11 in an open state.

[0031] When in use, the fixed sleeve 5 is sleeved on the front end of the endoscope, and as the endoscope enters the human body, the support channel 11 is in a retracted state, and the soft sleeve 9 is bent to the rear end of the fixed sleeve 5 by natural deformation, so as to facilitate smooth entry, reduce interference with the endoscope entering the human body, and also not interfere with the image observation at the image port 3. After entering the human body, the forceps enter through the instrument port 1 and complete the clamping action, further guide the sharp foreign matter to the front end of the endoscope, and further retract the endoscope. At this time, the soft sleeve 9 is naturally deformed to the fixed sleeve 5 At the front end, water is further discharged outward through the water outlet 4. On the one hand, the water flow enters the supporting channel 11 through the opening 12 on the mounting surface 6, thereby keeping the supporting channel 11 expanded and propped up, and the remaining part of the water flow can impact outward. The operator can adjust the water flow according to the direction of the water flow to properly flush the position of the foreign body, thereby determining whether there are other wounds or the specific conditions of the wounds. During the withdrawal process, the water outlet 4 stops supplying water, and the supporting channel 11 discharges the internal water flow under the natural squeezing inside the human body, and re-closes and adheres to the surface of the foreign body to reduce the overall volume and facilitate withdrawal.

[0032] Preferably, an elastic shrink ring 13 is provided at the opening 12 corresponding to the support channel 11, and the shrink ring 13 is used to open the opening 12 under the impact of water flow. Through the setting of the shrink ring 13, the opening 12 can be reduced to slow down the discharge speed of the water flow in the support channel 11, so that it is more suitable for use in endoscope scenes with larger space.

[0033] Preferably, the mounting surface 6 includes a guide surface 14 and a limiting surface 15 arranged on both sides of the guide surface 14, the guide surface 14 is arranged corresponding to the limiting block 7, the gap 8 is formed by the guide surface 14, the limiting block 7 and the limiting surface 15, and a guide opening 16 is formed corresponding to the edge of the guide surface 14, the guide opening 16 is arranged corresponding to the axis of the fixed sleeve, and the arrangement of the guide surface 14, the limiting block 7 and the limiting surface 15 makes the overall structure simpler and more reliable.

[0034] Preferably, thick layers 17 are formed corresponding to both sides of the support channel 11 of the soft sleeve 9, and thin layers 18 are formed at the remaining positions. Thus, for the sharp part of the foreign object, this part can be clamped corresponding to the thick layer 17 to avoid the possible risk of piercing, so as to further ensure the protection performance.

[0035] Preferably, both the fixed sleeve 5 and the soft sleeve 9 are made of transparent materials. Guide lines 19 are provided on both sides of the thick layer 17 corresponding to the soft sleeve 9. The guide lines 19 are used to guide the position of the thick layer 17 for convenient use.

[0036] Preferably, due to the increased risk of detachment of the fixed sleeve 5 from the endoscope under the impact of water flow, in order to further improve the fixing stability of the fixed sleeve 5 and the endoscope, an attaching belt 20 is provided at the rear end of the fixed sleeve 5. The attaching belt 20 is used to adhere and fix to the outer wall of the endoscope. The method of using the adhesive belt can greatly ensure the connection stability of the fixed sleeve 5.

[0037] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as within the protection scope of the present invention.
