Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for recovering intestinal polyp removal specimens. Background Technology

[0002] Removal of intestinal polyps is a common procedure in endoscopic examinations and treatments. The removed polyp specimen needs to be completely retrieved for pathological examination, which is crucial for disease diagnosis and the development of subsequent treatment plans.

[0003] Currently, the common method for recovering polyp specimens is to remove the specimen from the body using a foreign body basket or forceps, and then place it directly in gauze, a kidney dish, or a simple container. This method has several drawbacks: First, the specimen is exposed to air, making it prone to drying, deformation, or contamination, affecting pathological results; second, small or fragmented specimens are easily lost during removal and transfer; third, the procedure is cumbersome, increasing the workload of medical staff and the risk of contamination; and finally, temporary storage containers are inconvenient for specimen labeling, temporary storage, and transportation to the pathology department.

[0004] Therefore, there is an urgent need for a specialized device that can achieve rapid, sterile, and safe recovery of specimens, and facilitate their temporary storage, transportation, and transfer. Summary of the Invention

[0005] To overcome the existing problems, this application provides an intestinal polyp removal specimen recovery device that is easy to operate, has good sealing properties, can effectively protect the integrity of the specimen, and is easy to use.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is: An intestinal polyp removal specimen recovery device includes a collection container for receiving intestinal polyp specimens; A cover plate, which is detachably disposed at the end of the collection tank; A storage component is disposed inside the collection container; The storage assembly includes an end plate and an elastic element, the elastic element being a spring, the spring being sleeved inside the sleeve and abutting against the support rod, the end plate being movably connected to the inner wall of the collection tank, and the elastic element being located below the end plate and providing an elastic force that causes the end plate to move toward the cover plate. The inner side of the cover plate is provided with an abutment post; When the cover plate is connected to the collection tank, the abutting post presses against the end plate, compressing the elastic element, and the storage assembly is located inside the collection tank. When the cover plate separates from the collection tank, the elastic element drives the end plate and the storage assembly to move toward the opening of the collection tank.

[0007] Preferably, the storage assembly further includes a filter, a sleeve, and a support rod; the upper end of the sleeve is connected to the support rod, the upper end of the support rod is connected to the lower surface of the end plate, the lower end extends into the sleeve and can slide relative to it along the axial direction, the filter is located below the end plate, and the mesh size of the filter is smaller than the minimum size of the target polyp specimen.

[0008] Preferably, the upper surface of the end plate is provided with a circular groove, the size of which is the same as the size of the abutment post, for limiting the position of the abutment post.

[0009] Preferably, the end plate has a limiting block on its outer wall, and the inner wall of the collection tank has a limiting groove that matches the limiting block. The cooperation between the limiting block and the limiting groove is used to limit the vertical movement of the storage component.

[0010] Preferably, the collection tank is provided with a connecting cylinder at one end of the cover plate, the outer wall of the connecting cylinder is provided with threads, and the cover plate is provided with a connecting cap, which is used to connect with the connecting cylinder.

[0011] Preferably, the collection tank and the cover are made of transparent or translucent material, and the cover is connected to the open end of the collection tank by a threaded connection.

[0012] The advantages of the embodiments of this application are: When the lid is opened, the storage component automatically and smoothly lifts the specimen to the optimal retrieval position at the mouth of the container under the action of the elastic element. Doctors do not need to use any auxiliary tools to delve into the container to search. They can directly observe the whole appearance of the specimen and easily and accurately pick it up with tweezers. Especially for multiple, small or fragmented specimens, it avoids omissions or damage caused by obstructed vision and inconvenient operation, and simplifies the operation of the retrieval process after the specimen is recovered.

[0013] The filter structure provides soft support for the specimen during lifting and transportation, avoiding collisions and compression from the bottom of the rigid container. Simultaneously, the built-in storage components fix the relative position of the specimen, preventing it from rolling or rubbing freely inside the container, thus preserving the specimen's original morphology to the greatest extent possible. This is crucial for pathological examinations requiring evaluation of cut edges or directional embedding.

[0014] The sealed space formed by the collection container and the cover effectively prevents specimens from drying out, shrinking, or undergoing autolysis due to air exposure while awaiting testing. This provides high-quality raw materials for subsequent pathological slide preparation, directly improving the accuracy of pathological diagnosis. The entire device can be designed as a single-use sterile product at low cost. After use, it is disposed of as medical waste, fundamentally eliminating cross-infection caused by incomplete cleaning and disinfection. This meets the highest standards of modern medical infection control and simplifies the hospital's disinfection supply process. Attached Figure Description

[0019] This application provides a device for recovering intestinal polyp resection specimens, which solves the problems in the prior art. When the lid is opened, the storage component automatically and smoothly lifts the specimen to the optimal retrieval position at the mouth of the container under the action of the elastic element. Doctors do not need to use any auxiliary tools to delve into the container to search, and can directly observe the whole appearance of the specimen. Tweezers can easily and accurately pick it up. Especially for multiple, small or fragmented specimens, it avoids omissions or damages caused by obstructed vision and inconvenient operation, and simplifies the operation of the specimen retrieval process.

[0020] The filter structure provides soft support for the specimen during lifting and transportation, avoiding collisions and compression from the bottom of the rigid container. Simultaneously, the built-in storage components fix the relative position of the specimen, preventing it from rolling or rubbing freely inside the container, thus preserving the specimen's original morphology to the greatest extent possible. This is crucial for pathological examinations requiring evaluation of cut edges or directional embedding.

[0021] The sealed space formed by the collection container and the cover effectively prevents specimens from drying out, shrinking, or undergoing autolysis due to air exposure while awaiting testing. This provides high-quality raw materials for subsequent pathological slide preparation, directly improving the accuracy of pathological diagnosis. The entire device can be designed as a single-use sterile product at low cost. After use, it is disposed of as medical waste, fundamentally eliminating cross-infection caused by incomplete cleaning and disinfection. This meets the highest standards of modern medical infection control and simplifies the hospital's disinfection supply process.

[0022] The technical solution in this application is to solve the above problems, and the overall approach is as follows: This embodiment provides a specific structure for a device for recovering intestinal polyp resection specimens, such as... Figure 1-6 As shown, it includes a collection container 1 for storing intestinal polyp specimens. The collection container 1 is a cylindrical container with one end open, used for the final storage and preservation of intestinal polyp specimens. The collection container 1 is preferably made of transparent or semi-transparent medical-grade plastic to facilitate observation of the internal specimen condition. A connecting tube 4 is provided at the open end of the collection container 1, and the outer wall of the connecting tube 4 is machined with external threads. Cover plate 2, which is detachably installed at the end of collection tank 1; Storage component 3 is located inside collection container 1; The storage assembly 3 includes an end plate 31 and an elastic element. The elastic element is a spring, which is sleeved inside the sleeve 35 and abuts against the support rod 36. The end plate 31 is movably connected to the inner wall of the collection tank 1. The elastic element is located below the end plate 31 and provides an elastic force that moves the end plate 31 toward the cover plate 2. The inner side of the cover plate 2 is provided with an abutment post 6; When the cover plate 2 is connected to the collection tank 1, the abutting column 6 presses against the end plate 31, compressing the elastic element, and the storage component 3 is located inside the collection tank 1. When the cover plate 2 separates from the collection tank 1, the elastic element drives the end plate 31 and the storage assembly 3 to move toward the opening of the collection tank 1.

[0023] A support rod 36 is vertically connected to the center of the lower surface of the end plate 31. The sleeve 35 is a cylindrical structure with an open upper end, which is fixedly installed below the end plate 31. The lower end of the support rod 36 extends into the sleeve 35 and can slide relative to it along the axial direction of the sleeve 35. The spring is housed in the sleeve 35. The upper end of the spring abuts against the support rod 36, and the lower end abuts against the inner bottom wall of the sleeve 35 or a support fixed inside it. In its natural state, the elastic force of the spring drives the support rod 36 and the end plate 31 connected to it to move upward.

[0024] The storage assembly 3 also includes a filter screen 34, a sleeve 35, and a support rod 36. The upper end of the sleeve 35 is connected to the support rod 36, and the upper end of the support rod 36 is connected to the lower surface of the end plate 31. The lower end extends into the sleeve 35 and can slide relative to it along the axial direction. The filter screen 34 is located below the end plate 31. The mesh size of the filter screen 34 is smaller than the minimum size of the target polyp specimen. The filter screen 34 is fixedly installed below the end plate 31 and located on the periphery of the sleeve 35. The mesh size of the filter screen 34 is precisely designed to be smaller than the minimum size of the target polyp specimen to ensure that the specimen can be effectively intercepted on the filter screen 34, while liquid or small tissue debris can be filtered through.

[0025] The upper surface of the end plate 31 is provided with a circular groove 32, the size of which is the same as that of the abutment post 6, and is used to limit the position of the abutment post 6.

[0026] The end plate 31 has a limiting block 33 on its outer wall, and the inner wall of the collection tank 1 has a limiting groove 5 that is adapted to the limiting block 33. The cooperation between the limiting block 33 and the limiting groove 5 is used to limit the vertical movement of the storage component 3.

[0027] The storage component 3 is movably housed inside the collection tank 1. The end plate 31 is a circular plate structure, with its outer edge fitting with the inner wall of the collection tank 1, allowing it to slide up and down along the inner wall of the collection tank 1. A circular groove 32 is provided at the center of the upper surface of the end plate 31. The size of the circular groove 32 is the same as the size of the abutment post 6. When the cover plate 2 is tightened, the end of the abutment post 6 is inserted into and abuts against the circular groove 32, which plays a role in positioning and stabilizing pressure. To further limit the movement of the storage component 3, limit blocks 33 are symmetrically provided on the outer wall of the end plate 31. At the same time, a limit groove 5 adapted to the limit block 33 is provided axially at the corresponding position on the inner wall of the collection tank 1. The limit block 33 can slide up and down in the limit groove 5, but cannot rotate, thereby preventing the storage component 3 from rotating as a whole and limiting its extreme position of up and down movement.

[0028] The collection tank 1 is provided with a connecting cylinder 4 at one end of the cover plate 2. The outer wall of the connecting cylinder 4 is threaded. The cover plate 2 is provided with a connecting cover 7 inside, which is used to connect with the connecting cylinder 4.

[0029] The cover plate 2 is used to close the opening of the collection tank 1. It is made of transparent or semi-transparent material and is made of the same material as the collection tank 1. A connecting cover 7 is fixedly installed on the inner side of the cover plate 2. The inner wall of the connecting cover 7 is provided with internal threads. The internal threads cooperate with the external threads of the connecting cylinder 4 to achieve a detachable and sealed connection between the cover plate 2 and the collection tank 1. A stop post 6 is vertically fixed at the center of the side of the cover plate 2 facing the inside of the collection tank 1.

[0030] The collection tank 1 and the cover plate 2 are made of transparent or semi-transparent material, and the cover plate 2 is connected to the open end of the collection tank 1 by means of threaded connection.

[0031] When surgically removed polyp specimens need to be placed into the collection container, unscrew the cover plate 2. At this time, because the abutment post 6 of the cover plate 2 separates from the end plate 31, under the elastic restoring force of the spring, the end plate 31 and the entire storage assembly 3 are pushed towards the opening of the collection container 1 until the limiting block 33 on the end plate 31 reaches the upper end of the limiting groove 5. At this time, the end plate 31 and the filter screen 34 rise to a position close to the opening of the container, making it easier for the doctor to place multiple polyp specimens directly on the filter screen 34. After placement, align the cover plate 2 with the opening of the collection container 1 and tighten it. During this process, the abutment post 6 on the inner side of the cover plate 2 gradually presses down on the end plate 31, which in turn compresses the spring in the sleeve 35 through the support rod 36, driving the entire storage assembly 3 to move downward, ultimately allowing the specimen to be completely stored at the bottom of the collection container 1.

[0032] When a pathologist needs to remove a specimen for examination, they simply unscrew the cover 2 again. As the abutment post 6 moves upward and disengages from the end plate 31, the compressed spring immediately releases its elasticity, pushing the storage assembly 3, along with the filter 34 and all polyp specimens, to rise quickly and automatically to the vicinity of the container opening. This allows the doctor to easily and safely remove the target polyp specimen directly from the raised filter 34 without using tweezers, avoiding specimen damage or omission and greatly improving operational convenience and work efficiency.

[0033] Working principle: During the procedure, the doctor can remove the polyp and place it directly into the collection tank 1, where it falls into the filter screen 34. Then, the cover plate 2 is screwed on. During tightening, the abutment post 6 on the inner side of the cover plate 2 gradually presses against the end plate 31. The end plate 31 overcomes the spring force and moves downwards, causing the filter screen 34 to descend along with it via the support rod 36 until it is completely submerged in the collection tank 1. At this point, the device is in a sealed transport and temporary storage state.

[0034] When a specimen needs to be removed for pathological examination, the cover plate 2 is unscrewed. As the cover plate 2 moves upward, the abutment post 6 is released from pressure on the end plate 31. Under the restoring force of the spring, the end plate 31 is smoothly pushed upward. The end plate 31 is guided upward along the limiting groove 5 by the limiting block 33, which simultaneously moves the sleeve 35 upward. Due to the weight of the support rod 36 and the filter screen 34, its upward speed may be slightly slower than that of the end plate 31, resulting in relative sliding between the two. Finally, when the end plate 31 rises to its highest point, the filter screen 34 is also fully raised. At this time, the filter screen 34 and the polyp specimen inside are fully exposed above the jar opening. The doctor can easily pick up the specimen with tweezers. The whole process is safe, convenient, and hygienic.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
