Description

Technical Field

[0001] This utility model relates to an abnormal tissue collector, and more particularly to a visual esophageal cardia abnormal tissue collector, belonging to the field of medical devices. Background Technology

[0002] Early-stage esophageal and gastric cardia cancer refers to cancer cells confined to the mucosa or submucosa without lymph node metastasis, but it can still progress to advanced-stage tumors. A novel cell collector, a collection device made of polymeric sponge material developed in recent years, offers advantages in terms of ease of use, safety, high patient compliance, and technological, economic, and widespread applicability aspects.

[0003] Figure 5 This is a schematic diagram of the existing collection device. In the existing technology, the disposable lesion cell collection device uses a compressed sponge 26 placed in a soluble axial docking capsule 30. At the same time, a lifting line 31 is connected to the sponge 26, and the lifting line 31 extends to the outside of the axial docking capsule 30. The other end of the lifting line 31 is connected to a handle 32. During the examination, the patient swallows the capsule and the lifting line connected to it, and then drinks water to dissolve the capsule and expand the sponge. When pulled out, the sponge acts as a sampling swab to collect mucus, lesion cells or lesion tissue in the digestive tract and throat. Then it is stored in a preservation bottle. After a period of time, it undergoes pretreatment, slide preparation and staining, and then the cell structure is observed and analyzed under a microscope for diagnosis.

[0004] This type of cell collector has the following drawbacks: 1. When swallowing the capsule and the thread, you need to swallow the capsule and part of the thread first. You need to drink water continuously and swallow the thread from the outside in turn. Since the thread is made of cotton thread, it is easy to float in the water, which is very difficult to swallow and takes a long time. 2. Because the lifting line is positioned in the middle of the swallowing process, the capsule is prone to lateral movement in the esophagus due to the traction of the lifting line, which reduces the swallowing speed. 3. Even when diseased cells are collected promptly, they are difficult to locate, requiring further diagnosis; 4. It is easy to miss the detection. When lifting the suture from the esophagus, the difference in lifting speed may cause missed detection.

[0005] To improve screening efficiency and accuracy, a fast and accurate esophageal cardia abnormal tissue collector is needed for screening. Summary of the Invention

[0006] To address the problems of existing esophageal lesion cell collectors, such as difficulty in swallowing, low efficiency, easy omissions in screening, and unclear lesion locations, this utility model provides a visual esophageal cardia abnormal tissue collector. Its purpose is to perform targeted lesion cell collection under video guidance, improve screening efficiency, reduce omissions, improve collection accuracy, and ensure timely treatment for residents with illnesses in the area.

[0007] The technical solution of this utility model is: a visual esophageal cardia abnormal tissue collector, including a miniature camera, the miniature camera is connected to a miniature camera module, multiple miniature LED lights are arranged around the miniature camera, a wire with a traction rope is arranged on the miniature camera module at the opposite end of the miniature camera, an abnormal tissue collector is arranged around the wire with the traction rope at the rear of the miniature camera module, and the front end of the abnormal tissue collector is closely attached to the rear end of the miniature camera module. Furthermore, the abnormal tissue collector includes a pair of water-soluble capsules that are fastened together in the shape of a trough. One side of the fastened trough-shaped capsules is connected, and the other side is provided with a fastening lock. A wire hole is provided in the center of the trough-shaped capsule. Before fastening, the trough-shaped capsule has a cross-sectional structure that is divided into two through the center line. The capsule around the wire hole is filled with a compressed sponge. The sponge is fixed in the trough-shaped capsule on the back of the wire hole. A sealing surface is provided between the edge of the side with the fastening lock and the edge of the wire hole. The sealing surface is connected to both ends of the trough-shaped capsule. The sealing surface is made of the same material as the outer shell of the trough-shaped capsule. Furthermore, the conductor with traction rope includes a traction rope, a power line, and a signal line, each with an insulating layer on its outer periphery. The outer periphery of multiple wires and ropes is provided with an overall insulating layer. Under natural conditions, the conductor with traction rope has at least a portion outside the mouth with a spiral structure. Furthermore, the wire with the traction rope at the rear end of the miniature camera module is provided with a limiting part that matches the length of the trough-shaped capsule, and the limiting part is made of the same material as the insulating layer. Furthermore, the miniature camera module is connected to a computer host with a display via a wire.

[0008] The advantages of this invention are that by setting multiple miniature LED lights around a miniature camera, the specific situation inside the esophagus can be clearly seen on the monitor under the illumination of the lights. Under visual conditions, the camera can be positioned in front of the suspected lesion, and the trough-shaped capsule can be placed at the suspected lesion location. In some special cases, abnormal tissue can also be collected through the pylorus with the aid of visual operation. By having the patient drink water, the trough-shaped capsule dissolves, and the sponge absorbs water and expands. By pulling the wire with the traction rope, the sponge can be brought into contact with the esophagus or cardia, and esophageal or cardia mucus, lesion cells, or other abnormal tissues can be adhered to the sponge. After the visual esophageal or cardia abnormal tissue collector is pulled out of the mouth, it is stored in a preservation solution bottle. After a period of time, it undergoes pretreatment, slide preparation, staining, and then observation of cell structure analysis under a microscope for diagnosis. By designing the abnormal tissue collector as a pair of trough-shaped water-soluble capsules that are interlocked, it can be prepared before use. The water-soluble trough-shaped capsule is removed from the sealed bag and fastened to the guide wire with a traction rope between the miniature camera module and the limiting part for combined use. The limiting part facilitates its advancement into the esophagus or cardia, preventing displacement of the capsule. A sealing layer between the side with the fastening lock and the side wire hole facilitates compression of the filling sponge, improves the locking mechanism, and prevents the sponge from extending from the inside of the capsule to the outside. Connecting the camera to a computer allows for display of the esophageal condition, aiding in the location of abnormalities and cell sampling. The spiral structure of the guide wire with the traction rope facilitates the pushing of the collector within the esophagus during rotation, changing the current method of swallowing the capsule solely through warm water. Furthermore, the swallowing motion of the capsule in the esophagus changes from lateral to longitudinal movement, reducing the obstruction of the lifting wire, increasing the pushing speed of the collector, and altering the direction of movement of the capsule in the test tube. By utilizing this visual esophageal and cardia abnormal tissue collector, targeted abnormal tissue collection can be performed under video guidance, which can improve screening efficiency, reduce omissions, improve collection accuracy, and ensure early detection and treatment of diseased residents in the jurisdiction.

Detailed Implementation

[0015] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] The technical solution of this utility model is a visual esophageal and gastric cardia abnormal tissue collector. Figure 1 This is a schematic diagram of the overall structure of this utility model. The visual esophageal cardia abnormal tissue collector includes a miniature camera 10a, which is connected to a miniature camera module 10. Multiple miniature LED lights 10b are arranged around the miniature camera 10a. A wire 13 with a traction rope is arranged on the miniature camera module 10 at the opposite end of the miniature camera 10a. An abnormal tissue collector is arranged around the wire 13 with the traction rope at the rear of the miniature camera module 10. The end of the abnormal tissue collector is closely attached to the rear end of the miniature camera module 10.

[0017] Figure 2 This is a schematic diagram of the capsule's unfolded structure. Figure 3 This is a schematic diagram of a capsule containing a sponge unfolding. Figure 4 It is along Figure 3Enlarged cross-sectional view along the AA direction. The abnormal tissue collector includes a pair of trough-shaped, water-soluble capsules that snap together. One side of the snapped-together capsules 11 is connected by a connecting part 25, and the other side is provided with a snap-lock 24. A wire hole 22 is provided in the center of the trough-shaped capsules 11. Before snapping, the two sides of the trough-shaped capsules 11 have a cross-sectional structure that is divided into two parts through the center line. The wire hole 22 is also divided into two parts, namely the left half wire hole 22a and the right half wire hole 22b. The outer trough-shaped capsules 11 are filled with compressed sponge 26, which is used for fixation. On the back of the wire hole 22, a sealing surface is provided between the side edge with the fastening lock 24 and the side edge of the wire hole 22. The sealing surfaces on both sides of the trough-shaped capsule 11 in cross-section are the left sealing surface 23a and the right sealing surface 23b, respectively. In this embodiment, the left sealing surface 23a and the right sealing surface 23b are respectively provided with fastening lock holes 24a and fastening locks 24b. The left sealing surface 23a and the right sealing surface 23b are respectively connected to the sealing of both ends of the trough-shaped capsule 11. The sealing surface 22 is made of the same material as the outer shell of the trough-shaped capsule 11. The abnormal tissue collector contains a certain amount of sodium chloride, which helps patients secrete saliva, reduces the feeling of swallowing a foreign body, and improves patient compliance.

[0018] The trough-shaped capsule 11 is made of gelatin, which dissolves upon contact with gastric juice. It can also be made of polymer materials. The sponge is polyurethane sponge, which can expand to 10 times its original volume. Because one end of the capsule end 21 of the trough-shaped capsule 11 contacts the miniature camera module 10 and the other end contacts the limiting part 12, it does not dislodge from the esophagus during swallowing. Therefore, it differs from commonly used arc-shaped capsules.

[0019] The conductor 13 with a traction rope includes a traction rope, a power cord, and a signal line. Each of these components has an insulation layer on its outer periphery. The outer periphery of the multiple wires and the traction rope is provided with an overall insulation layer. Under normal conditions, at least part of the conductor 13 with a traction rope outside the mouth has a spiral structure. The other end of the conductor is provided with a plug 14 for connection to the computer host.

[0020] The miniature camera module 10 has a limiting part 12 on the wire 13 with a traction rope at the rear end, which matches the length of the trough-shaped capsule 11.

[0021] The miniature camera module 10 is connected to a computer host with a display via a wire. The miniature camera module 10 is a capsule endoscope, which is small in size, has a smooth outer surface, is painless when swallowed, requires no anesthesia, and is similar to a regular pharmaceutical capsule. It will not cause vomiting or nausea, and can visualize esophageal fibroids, cysts, etc.

[0022] The positive effects of this invention are that by setting multiple miniature LED lights 10b around the miniature camera 10a, the specific situation inside the esophagus and cardia can be clearly seen on the monitor under the illumination of the lights. Under visual conditions, the camera 10a can be positioned in front of the suspected lesion, and the trough-shaped capsule 11 can be placed at the suspected lesion location. In some special cases, abnormal tissue can also be collected through the pylorus with the help of visual operation. By having the patient drink water, the trough-shaped capsule 11 dissolves, and the sponge 26 absorbs water and expands. The sponge 26 can be connected to the esophagus by pulling the wire 13 with the traction rope. The abnormal tissue, such as esophageal mucus, diseased cells, or lesions, is collected on a sponge 26. After being pulled out of the mouth, the visible esophageal cardia abnormal tissue collector is stored in a preservation solution bottle. After a period of time, it undergoes pretreatment, slide preparation, and staining, followed by microscopic observation and analysis of cell structure for diagnosis. The abnormal tissue collector is designed as a pair of trough-shaped, interlocking water-soluble trough-shaped capsules 11. Before use, the water-soluble trough-shaped capsules 11 can be removed from the sealed bag and attached to the wire 13 with a traction rope between the miniature camera module 10 and the limiting part 12 for combined use. The limiting part... 12. This facilitates the advancement into the esophagus and prevents displacement of the trough-shaped capsule 11. By setting a left sealing surface 23a and a right sealing surface 23b between the side edge with the locking buckle 24 and the side edge of the corresponding lateral hole 22, it is beneficial to compress the filling sponge 26 and to engage the locking buckle 24, preventing the sponge 26 from extending from the inside of the trough-shaped capsule 11 to the outside. By connecting the camera 10a to a computer, the condition inside the esophagus can be displayed on the monitor, which is beneficial for locating lesions and for cell sampling. By designing the guide wire 13 with the traction rope as a spiral structure, it is beneficial to push the collector into the esophagus during rotation. This new method changes the existing swallowing method of the trough-shaped capsule 11, which relies entirely on warm water for propulsion. Furthermore, the swallowing mechanism of the trough-shaped capsule 11 in the esophagus has been changed from the original lateral movement of the axially aligned capsule 30 to the longitudinal movement of the trough-shaped capsule 11. This reduces the obstruction caused by the lifting thread, increases the pushing speed of the collector, and alters its movement direction in the esophagus. By utilizing this visual esophageal and cardia abnormal tissue collector, targeted collection of abnormal tissue or lesion cells can be performed under video guidance, improving screening efficiency, reducing omissions, enhancing patient compliance and collection accuracy, and ensuring timely treatment for affected residents in the area.
