Description

Technical Field

[0001] The present invention relates to the technical field of digestive endoscopy, and particularly relates to a protective structure and a protection method for the head of a digestive endoscope. Background Art

[0002] In the medical field, as an important diagnostic and treatment tool, the hygiene safety and efficient use of digestive endoscopes have always been the focus of attention of medical staff. During the use and storage of traditional digestive endoscopes, the head of the endoscope body is easily contaminated and damaged by the external environment, which not only affects the service life of the endoscope, but may also cause cross-infection and endanger the health of patients.

[0003] Most of the existing protective structures for digestive endoscopes use simple rigid protective shells and internally filled flexible materials for protection. For example, according to the "protective cap for the front end of a digestive endoscope" provided by the Chinese Patent Grant Publication No. CN219250119U, the push handle can be pulled by the reaction force of the spring through the clamping mechanism, so as to fix the digestive endoscope. The head of the digestive endoscope is inserted into the inner cavities of the upper shell, the clamping mechanism and the rear end cover, and the head of the digestive endoscope is inserted into the groove of the inner foam. This setting can protect the head of the digestive endoscope and prevent damage to the head of the digestive endoscope caused by shaking. This setting tightly fixes the protective cap to the digestive endoscope pipeline and will not fall off when interfering with different devices during transportation. At the same time, this protective cap can be installed and protected according to different sizes of digestive endoscopes, and only need to rotate the push handle at different angles in the arc-shaped opening.

[0004] The above patent realizes the protection of the head of the digestive endoscope through the combination of a rigid protective cap and inner foam. However, this protection is for the protection of the digestive endoscope during transportation. The body and the head of the digestive endoscope also need protection during use and after cleaning and vertical placement. For example, when the digestive endoscope is inserted into the stomach and comes into contact with the internal liquid, it is easy to cause cross-infection, and there are also safety risks when it is vertically placed and exposed to the air after cleaning. And the efficiency of self-heating drying during cleaning and placement is relatively low.

[0005] Therefore, it is particularly important to develop a protective structure and a protection method that can not only effectively protect the head of the digestive endoscope from damage and contamination, but also efficiently disinfect and dry. Summary of the Invention

[0006] The present invention provides a protective structure and a protection method for the head of a digestive endoscope, which solve the above-mentioned technical problems.

[0007] To solve the above technical problems, a protective structure for the head of a digestive endoscope provided by the present invention includes an endoscope body fixedly installed on an operation part, a protection structure is sleeved and installed outside the endoscope body, and a head protection structure is sleeved and installed at the tail of the protection structure;

[0008] The protection structure includes a protective sleeve fixedly connected to the fixed end.

Four groups of adjustable blowing structures are fixedly installed on the upper side wall inside the protection cylinder. A partition is fixedly installed at the lower part inside the protection cylinder, and an annular shunt pipe is fixedly installed at the bottom of the partition. A control module is installed below the annular shunt pipe in the protection cylinder. A plurality of ventilation holes are formed above the partition on the lower outer side of the protection cylinder, and a heat dissipation hole group is formed at the bottom of the protection cylinder. A control panel is also fixedly installed on one side of the bottom of the protection cylinder. The lens body together with the sleeved protective sleeve penetrates the locking structure and is inserted into the interior of the protection cylinder, and the four groups of airbags correspond to the four groups of adjustable blowing structures.

[0010] Furthermore, the protective sleeve is a variable stiffness corrugated pipe, which is composed of a 304 stainless steel corrugated pipe and a silicone composite structure, and a polyurethane-based honeycomb structure is arranged inside the protective sleeve.

[0011] Furthermore, silicone layers are fixedly installed inside the through hole of the fixed end and inside the clamping block.

[0012] Furthermore, the inflation end is connected to an external air inflation pump through a hose for inflating the four groups of airbags.

[0013] Furthermore, a suction nozzle is fixedly installed on one side of the outside of the protection cylinder for adsorbing and fixing to an external smooth wall surface.

[0014] Furthermore, the locking structure includes a tapered threaded head fixed on the top of the protection cylinder. A plurality of slots are formed at the top of the tapered threaded head. A fixed sleeve is threadedly connected to the outside of the tapered threaded head. Communication holes penetrate through the fixed sleeve and the middle part of the tapered threaded head, and the communication holes communicate with the interior of the protection cylinder.

[0015] Furthermore, the control module includes an air charging and discharging pump, a control main board, a heating film, an ultraviolet lamp and a storage battery. The storage battery and the air charging and discharging pump are fixed at the bottom of the protection cylinder. The output end of the air charging and discharging pump is fixedly communicated with the annular shunt pipe through a hose. The control main board is fixed at the lower part inside the protection cylinder and is electrically connected to the storage battery and the air charging and discharging pump.

[0017] Further, the blowing nozzle is fixedly communicated with the annular shunt pipe through a hose penetrating through the partition plate, and the air outlet holes of the blowing nozzle are opened upward at the inclined end.

[0018] A method for protecting the head of a digestive endoscope

[0019] S1. Install the protection structure for use protection: Grasp the endoscope body and fully insert it into the protective sleeve. Rotate the locking screw at the fixed end to drive the clamping block to clamp the endoscope body.

[0020] S2. Protection during use: When the endoscope body is inserted into the patient's stomach, the protective sleeve follows in, effectively preventing the outer wall of the endoscope body from contacting the gastric fluid and preventing cross-infection. If the camera is compressed in the gastric passage and the line of sight is blocked, connect an external air pump to the inflation end to inflate the four groups of air bags to expand and open the gastric passage to ensure that the camera's line of sight is unobstructed.

[0021] S3. Protection during storage after cleaning: When the digestive endoscope is cleaned and vertically hung, insert the head of the endoscope body through the locking structure into the protection cylinder and lock and fix it. The protective sleeve covers the head of the endoscope body to prevent damage from collision with external objects.

[0022] S4. Disinfection stage during storage after cleaning: Send a command to the control main board through the control panel. The control main board controls the ultraviolet lamp to light up to irradiate and disinfect the head of the endoscope body to prevent bacterial growth.

[0023] S5. Drying stage during storage after cleaning: Similarly, send a command through the control panel. The control main board integrates a temperature control module to control the graphene heating film to generate heat at a constant temperature. Start the air charging and discharging pump to extract external air and input it into the protection cylinder. After heating through the annular shunt pipe, it is shunted to the blowing nozzles of the four groups of adjustable blowing structures to blow out hot air. The hot air blows towards the head of the endoscope body for drying to ensure complete drying of the head and the inside of the endoscope body.

[0024] S6. In the above S5, when the protective cover of the mirror body is inserted into the connecting tube, the four groups of air bags are inflated and deflated through the external air pump and the inflation end. When the air bags expand, the push plate is squeezed to compress the limit spring. The squeezed push plate drives the linkage bent plate to flip through the connecting shaft, so that the blowing nozzle is tilted and moved upward, and the blowing position and angle are flexibly adjusted to blow and dry the dead corner of the end of the mirror body. After the air bags shrink, the limit spring rebounds and drives the push plate to return to its position, and the torsion spring returns the linkage bent plate and the blowing nozzle, and so on and so forth to improve the drying efficiency.

[0025] Compared with the related art, the protective structure and method for the head of a digestive endoscope provided by the present invention have the following beneficial effects:

[0026] The present invention provides a protective structure in which a protective cover is put on the outside of the endoscope body and then enters the stomach, thereby effectively preventing the outer wall of the endoscope body from contacting the stomach fluid, preventing cross infection, and improving safety. The protective cover serves as a variable stiffness bellows, and adopts a 304 stainless steel bellows and a silicone composite structure, which provides sufficient flexibility and durability. The polyurethane-based honeycomb structure inside the protective cover enhances its structural strength and prolongs the service life of the endoscope.

[0027] The present invention provides that four groups of air bags are arranged at the head of the mirror body at the tail of the protective cover. When the camera head of the digestive endoscope is compressed in the stomach passage and its sight is blocked, an external air pump can be connected to the inflation end to inflate, so that the four groups of air bags expand and the stomach passage at the head of the mirror body is opened, so that the camera is not blocked and it is convenient to shoot the stomach condition. It is relatively convenient and improves the inspection efficiency. It can also provide additional buffering and protection for the mirror body to prevent the head of the mirror body from being damaged during use.

[0028] The present invention provides a head protection structure. When the digestive endoscope is used and cleaned, it is hung vertically, the head of the mirror body passes through the locking structure and enters the interior of the protection tube and is locked and fixed. The protective cover covers the head of the mirror body to prevent it from being damaged by collision with external objects. The control panel sends instructions to the control main board to control the ultraviolet lamp to light up, irradiate and disinfect the head of the mirror body to prevent bacteria from growing. The graphene heating film can also be controlled to heat at a constant temperature and the charging and discharging air pump can be started to blow out hot air. The hot air is blown to the head of the mirror body for drying, thereby ensuring that the head of the mirror body and the interior are completely dry.

[0029] The present invention provides that the head of a digestive endoscope lens can be put into a protective cover and enter into a protective tube, the air bag on the protective cover corresponds to the blowing adjustment structure, and the air bag is expanded and contracted by inflating and deflating air through an external air pump. When the air bag is expanded, the abutment plate is squeezed, and the linkage bent plate rotates and tilts up, driving the blowing nozzle to tilt and blow air, and the position angle can be flexibly adjusted to dry the dead corner at the end of the lens body. After the air bag is contracted, the abutment plate and the linkage bent plate are reset by a spring, and move back to improve the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Example 1, consisting of Figures 1-9Provided is a protective structure for the head of a digestive endoscope, including a lens body 1 fixedly installed on an operation part 11. A protective structure 2 is sleeved and installed outside the lens body 1. The protective structure 2 includes a protective sleeve 22 fixedly connected to a fixed end 21. Four groups of air bags 25 are fixed on the outer side of the tail of the protective sleeve 22. An inflation end 24 is fixed outside the protective sleeve 22. A conveying channel is arranged inside the protective sleeve 22. Both ends of the conveying channel are communicated with the four groups of air bags 25 and the inflation end 24 respectively. A displacement groove is formed in the side wall of the through hole of the fixed end 21, and a clamping block 26 is arranged in the displacement groove. A locking screw 23 is threadedly connected to the outside of the fixed end 21, and the locking screw 23 threadedly penetrates through the fixed end 21 and is rotationally connected to the clamping block 26.

[0041] Specifically, hold the lens body 1 and insert the tail into the through hole of the fixed end 21 so that the lens body 1 enters the inside of the protective sleeve 22. The length of the protective sleeve 22 is shorter than that of the lens body 1. After the lens body 1 is completely inserted, rotate the locking screw 23 of the fixed end 21 to drive the clamping block 26 to move in the displacement groove to clamp the lens body 1. When the lens body 1 is inserted into the patient's stomach, the protective sleeve 22 follows and enters the stomach, effectively preventing the outer wall of the lens body 1 from contacting the gastric fluid, preventing cross-infection and improving safety.

[0042] Among them, the protective sleeve 22 is a variable stiffness corrugated pipe, which is composed of a 304 stainless steel corrugated pipe and a silica gel composite structure, and a polyurethane-based honeycomb structure is arranged inside the protective sleeve 22; the protective sleeve 22 not only has sufficient stiffness to provide protection, but also has a certain flexibility to adapt to different use environments and operating conditions. At the same time, the selection of these materials also ensures the durability and long life of the protective sleeve.

[0043] Among them, silica gel layers are fixedly installed inside the through hole of the fixed end 21 and inside the clamping block 26, so as to effectively buffer when the clamping block 26 clamps the lens body 1.

[0044] Among them, the inflation end 24 is connected to an external air pump hose for inflating the four groups of air bags 25. When the external air pump is started, gas is sent into the conveying channel inside the protective sleeve 22 through the inflation end 24, and then into the four groups of air bags 25. After the air bags 25 expand, they can not only expand the gastric channel, but also provide additional buffering and protection for the lens body 1 to prevent the head of the lens body from being damaged during use.

[0045] Embodiment 2, based on Embodiment 1, a head protection structure 3 is sleeved and installed at the tail of the protection structure 2. The head protection structure 3 includes a locking structure fixed to the top of the protection cylinder 31. Four groups of adjustable blowing structures 37 are fixedly installed on the upper side wall inside the protection cylinder 31. A partition is fixed inside the lower part of the protection cylinder 31, and an annular flow dividing pipe 36 is fixed to the bottom of the partition. A control module 35 is installed below the annular flow dividing pipe 36 in the protection cylinder 31. A plurality of air permeable holes 311 are opened above the partition on the lower part outside the protection cylinder 31, and a heat dissipation hole group 312 is opened at the bottom of the protection cylinder 31. A control panel 313 is also fixed to one side of the bottom of the protection cylinder 31. The lens body 1 together with the sleeved protective cover 22 passes through the locking structure and is inserted into the interior of the protection cylinder 31, and the four air bags 25 correspond to the four groups of adjustable blowing structures 37.

[0046] Specifically, when the digestive endoscope is cleaned and vertically hung on the wall for placement, it can be sleeved with the protection structure for protection, that is, the head of the digestive endoscope passes through the locking structure and enters the interior of the protection cylinder 31, and then the locking structure is locked and fixed, so that the head of the lens body 1 is covered and protected by the protective cover 22, preventing it from being damaged by collision with external objects and improving safety. The control module 35 is arranged inside the protective cover 22 and can disinfect and dry the head of the lens body 1.

[0047] Among them, a suction nozzle 32 is fixed to one side outside the protection cylinder 31 for adsorbing and fixing to a smooth external wall; the protective cover 22 can be adsorbed and fixed to the wall through the suction nozzle 32, reducing the pulling force on the lens body 1.

[0048] In this embodiment, the locking structure includes a tapered threaded head 34 fixed to the top of the protection cylinder 31. A plurality of slots 341 are opened at the top of the tapered threaded head 34. An outer threaded fixed sleeve 33 is connected to the outside of the tapered threaded head 34. Communication holes are penetrated through both the fixed sleeve 33 and the middle part of the tapered threaded head 34, and the communication holes are communicated with the interior of the protection cylinder 31; the head of the digestive endoscope passes through the fixed sleeve 33 and the tapered threaded head 34 and enters the interior of the protection cylinder 31, and then the fixed sleeve 33 is rotated to be threadedly matched with the tapered threaded head 34 to contract and clamp and fix the lens body 1.

[0049] In this embodiment, the control module 35 includes an air charging and discharging pump 351, a control main board 352, a heating film 353, an ultraviolet lamp 354 and a storage battery 355. The storage battery 355 and the air charging and discharging pump 351 are fixed to the bottom of the protection cylinder 31. The output end of the air charging and discharging pump 351 is fixedly communicated with the annular flow dividing pipe 36 through a hose. The control main board 352 is fixed to the lower part inside the protection cylinder 31 and is electrically connected to the storage battery 355 and the air charging and discharging pump 351. The heating film 353 is fixed to the bottom of the annular flow dividing pipe 36 and is electrically connected to the control main board 352. The ultraviolet lamp 354 is fixed to the middle of the top of the partition and is electrically connected to the control main board 352. The control panel 313 is electrically connected to the control main board 352.

[0050] Specifically, instructions are sent to the control main board 352 through the control panel 313. The control main board 352 controls the ultraviolet lamp 354 to turn on for disinfecting the head of the lens body 1 by irradiation, effectively preventing bacterial growth, improving hygiene and safety, and enabling direct use in the later stage. Instructions are sent to the control main board 352 through the control panel 313. The control main board 352 is integrated with a temperature control module to control the graphene heating film 353 to generate heat at a constant temperature, thereby heating the annular shunt pipe 36 made of aluminum alloy. At the same time, the air charging and discharging pump 351 is started to extract external air and input it into the protection cylinder 31. The compressed air is heated through the hose and input into the annular shunt pipe 36, and then is shunted to the blowing nozzles 375 of the four groups of adjustable blowing structures 37 and blown out. The hot air blows towards the head of the lens body 1 for drying, ensuring complete drying of the head and inside of the lens body 1, and the generated water vapor is discharged from a plurality of air vent holes 311.

[0051] In this embodiment, the adjustable blowing structure 37 includes a U-shaped seat 371 fixed on the inner side wall of the protection cylinder 31. A limiting spring 373 is fixed in the middle of the U-shaped seat 371. An end plate 372 is fixed to the outer end of the limiting spring 373. A connecting shaft 376 is rotatably connected to the front part inside the U-shaped seat 371. A linkage bent plate 374 is fixed in the middle of the connecting shaft 376 and is adapted to be linked with the end plate 372. Torsion springs 3761 are sleeved and installed on the left and right edges of the connecting shaft 376. A blowing nozzle 375 is fixedly penetrated and fixed at the lower bottom of the linkage bent plate 374. The blowing nozzle 375 is fixedly communicated with the annular shunt pipe 36 through a hose penetrating through the partition plate, and the air outlet holes of the blowing nozzle 375 are opened upward at the inclined end.

[0052] Specifically, the head of the digestive endoscope can be inserted into the protection sleeve 22, penetrate through the fixing sleeve 33 and the tapered threaded head 34 and enter the inside of the protection cylinder 31. The four groups of air bags 25 on the protection sleeve 22 are in corresponding contact with the four groups of adjustable blowing structures 37. The fixing sleeve 33 and the tapered threaded head 34 are rotationally locked by threads. When drying by blowing, an external air pump is connected to the inflation end 24 for inflation and deflation, so that the four groups of air bags 25 expand and contract back and forth. When the air bag 25 expands, the inflated air pump presses the end plate 372, driving the displacement of the end plate 372 to squeeze the limiting spring 373. The displacement of the end plate 372 contacts and presses the head of the linkage bent plate 374, so that the linkage bent plate 374 rotates and tilts upward through the connecting shaft 376, driving the blowing nozzle 375 to displace obliquely upward for blowing. The position and angle can be flexibly adjusted to blow and dry the dead corner position at the end of the lens body 1, improving the drying efficiency. After the air bag 25 contracts, the limiting spring 373 rebounds to drive the end plate 372 to return to its original position. A torsion spring 3761 is arranged on the connecting shaft 376 to contract and store energy when the linkage bent plate 374 rotates. After the end plate 372 returns to its original position, the linkage bent plate 374 returns to its original position under the rebound of the torsion spring 3761, driving the blowing nozzle 375 to move back to its original position. Displacing back and forth in this way greatly improves the drying efficiency of the hot air blowing.

[0053] Embodiment 3: A method for protecting the head of a digestive endoscope includes the following steps:

[0054] S1. Install the protection structure for use protection: Grasp the lens body 1 and insert it completely into the protective sleeve 22. Rotate the locking screw 23 of the fixed end 21 to drive the clamping block 26 to clamp the lens body 1; S2. Protection during use: When the lens body 1 is inserted into the patient's stomach, the protective sleeve 22 follows and enters, effectively preventing the outer wall of the lens body from contacting the gastric fluid and preventing cross-infection. If the camera is compressed in the gastric passage and the line of sight is blocked, connect an external air pump to the inflation end 24 to inflate the four groups of airbags 25 to make them expand and open the gastric passage to ensure that the camera's line of sight is not blocked; S3. Store and protect after cleaning: When the digestive endoscope is used and cleaned, hang it vertically. Pass the head of the lens body 1 through the locking structure and into the protective cylinder 31 and lock and fix it. The protective sleeve 22 covers the head of the lens body to prevent damage from collision with external objects; S4. Disinfection stage after cleaning and storage: Send a command to the control main board 352 through the control panel 313. The control main board 352 controls the ultraviolet lamp 354 to light up to irradiate and disinfect the head of the lens body 1 to prevent bacterial growth; S5. Drying stage after cleaning and storage: Similarly, send a command through the control panel 313. The control main board 352 integrates a temperature control module to control the graphene heating film 353 to generate heat at a constant temperature. Start the air charging and discharging pump 351 to extract external air and input it into the protective cylinder 31. After heating through the annular shunt pipe 36, it is shunted to the blowing nozzles 375 of the four groups of adjustable blowing structures 37 to blow hot air. The hot air blows towards the head of the lens body 1 for drying to ensure complete drying of the head and inside of the lens body; S6. In the above S4, when the lens body 1 is sleeved with the protective sleeve 22 and inserted into the connecting cylinder, the four groups of airbags 25 are inflated and deflated through an external air pump and the inflation end 24. When the airbag 25 expands, it squeezes the pressing plate 372 to compress the limit spring 373. The pressing plate 372 drives the linkage bent plate 374 to flip through the connecting shaft 376, so that the blowing nozzle 375 is displaced obliquely upward, flexibly adjusting the blowing position and angle to blow and dry the dead corner position at the end of the lens body 1. After the airbag 25 contracts, the limit spring 373 rebounds to drive the pressing plate 372 to return to its original position, and the torsion spring 3761 makes the linkage bent plate 374 and the blowing nozzle 375 return to their original positions. This process is repeated to improve the drying efficiency.

[0055] The specific implementation method is as follows:

[0056] Installation protection structure 2: Grasp the endoscope body 1 and insert the tail into the through-hole of the fixed end 21, so that the endoscope body 1 enters the inside of the protective sleeve 22. The length of the protective sleeve 22 is shorter than that of the endoscope body 1. After the endoscope body 1 is completely inserted, rotate the locking screw 23 of the fixed end 21 to drive the clamping block 26 to move in the displacement groove to clamp the endoscope body 1. When the endoscope body 1 is inserted into the patient's stomach, the protective sleeve 22 follows and enters the stomach, effectively preventing the outer wall of the endoscope body 1 from contacting the gastric fluid, preventing cross-infection, improving safety, and the protective sleeve 22 is a variable stiffness corrugated pipe, adopting a composite structure of 304 stainless steel corrugated pipe and silica gel, providing sufficient flexibility and durability. The polyurethane-based honeycomb structure inside it enhances its structural strength and extends the service life of the endoscope. Four groups of air bags 25 are arranged at the tail of the protective sleeve 22 at the head position of the endoscope body 1. When the camera at the head of the digestive endoscope is compressed in the gastric passage and blocks the line of sight, an external air pump can be connected to the inflation end 24 for inflation. Thus, the four groups of air bags 25 expand to open the gastric passage at the head of the endoscope body 1, so that the camera is unobstructed and it is convenient to photograph the gastric condition, which is relatively convenient and improves the inspection efficiency:

[0057] When the digestive endoscope is cleaned and vertically hung on the wall for placement, it can be protected by being sleeved with a protective structure, that is, the head of the digestive endoscope penetrates the fixed sleeve 33 and the tapered threaded head 34 and enters the inside of the protective cylinder 31, and then rotate the fixed sleeve 33 to thread-fit with the tapered threaded head 34 to contract and clamp and fix it with the endoscope body 1. Thus, the head of the endoscope body 1 is covered and protected by the protective sleeve 22 to prevent damage caused by collision with external objects, improving safety, and the protective sleeve 22 can be adsorbed and fixed on the wall through the suction nozzle 32, reducing the pulling force on the endoscope body 1;

[0058] A control module 35 is arranged inside the protective sleeve 22, which can disinfect and dry the head of the endoscope body 1:

[0059] Send an instruction to the control main board 352 through the control panel 313, and the control main board 352 controls the ultraviolet lamp 354 to light up and irradiate the head of the endoscope body 1 for disinfection, effectively preventing the growth of bacteria, improving hygiene and safety, and it can be directly used later;

[0060] Send an instruction to the control main board 352 through the control panel 313. The control main board 352 is integrated with a temperature control module to control the graphene heating film 353 to generate heat at a constant temperature, so as to heat the aluminum alloy annular flow dividing pipe 36. At the same time, start the air charging and discharging pump 351 to extract external air and input it into the protective cylinder 31. The compressed air is input into the annular flow dividing pipe 36 through the hose for heating, and then is divided and blown out from the blowing nozzles 375 of the four groups of adjustable blowing structures 37. The hot air blows towards the head of the endoscope body 1 for drying, ensuring the complete drying of the head and inside of the endoscope body 1, and the generated water vapor is discharged from multiple air permeable holes 311;

[0061] The digestive endoscope head can be inserted into the protective cover 22, pass through the fixed sleeve 33 and the conical threaded head 34 and enter the inside of the protective cylinder 31. The four groups of airbags 25 on the protective cover 22 are in contact with the four groups of adjustable blowing structures 37 correspondingly. The fixed sleeve 33 and the conical threaded head 34 are threadedly rotated and locked. When drying by blowing, an external air pump is connected to the inflation end 24 for inflation and deflation, so that the four groups of airbags 25 expand and contract back and forth. When the airbag 25 expands, the inflated airbag squeezes the pressing plate 372, driving the displacement of the pressing plate 372 to squeeze the limit spring 373. The displacement of the pressing plate 372 contacts and squeezes the head of the linkage bent plate 374. Thus, the linkage bent plate 374 rotates and tilts upward through the connecting shaft 376, driving the blowing nozzle 375 to displace obliquely upward for blowing. The position and angle can be flexibly adjusted to blow and dry the dead corner position at the end of the endoscope body 1, improving the drying efficiency. After the airbag 25 contracts, the limit spring 373 rebounds to drive the pressing plate 372 to return to its original position. A torsion spring 3761 is arranged on the connecting shaft 376 to contract and store energy when the linkage bent plate 374 rotates. After the pressing plate 372 returns to its original position, the linkage bent plate 374 returns to its original position under the rebound of the torsion spring 3761, driving the blowing nozzle 375 to move back to its original position. Displacing back and forth like this greatly improves the drying efficiency of hot air blowing.

10. A method for protecting the head of an endoscope for digestion, characterized in that, It includes the following steps: S1. Install the protection structure for use protection: Grasp the lens body (1) and completely insert it into the protection sleeve (22), and rotate the locking screw (23) at the fixed end (21) to drive the clamping block (26) to clamp the lens body (1); S2. Protection during use: When the lens body (1) is inserted into the patient's stomach, the protection sleeve (22) follows and enters, effectively preventing the outer wall of the lens body from contacting the gastric fluid and preventing cross-infection. If the camera is compressed in the gastric passage and the line of sight is blocked, connect an external air pump to the inflation end (24) to inflate the four groups of air bags (25) to expand and open the gastric passage to ensure that the line of sight of the camera is not blocked; S3. Protect and store after cleaning: When the digestive endoscope is cleaned and vertically hung, insert the head of the lens body (1) through the locking structure into the inside of the protection cylinder (31) and lock and fix it. The protection sleeve (22) covers the head of the lens body to prevent damage caused by collision with external objects; S4. Disinfection stage during storage after cleaning: Send an instruction to the control main board (352) through the control panel (313), and the control main board (352) controls the ultraviolet lamp (354) to light up to irradiate and disinfect the head of the lens body (1) to prevent bacterial growth; S5. Cleaning and dry storage stage: Similarly, send an instruction through the control panel (313) to control the integrated temperature control module of the main board (352) to control the graphene heating film (353) to generate heat at a constant temperature. Start the air charging and discharging pump (351) to extract external air and input it into the protection cylinder (31). After heating through the annular shunt pipe (36), it is shunted to the air blowing nozzles (375) of the four groups of adjustable air blowing structures (37) to blow out hot air, and the hot air blows towards the head of the lens body (1) for drying to ensure complete drying of the head and the inside of the lens body. S6. In S4, when the lens body (1) is sleeved with the protective cover (22) and inserted into the connecting cylinder, the four groups of air bags (25) are inflated and deflated through the external air pump and the air charging end (24). When the air bags (25) expand, they squeeze the abutting plate (372) to compress the limiting spring (373). The squeezing of the abutting plate (372) drives the linkage bent plate (374) to flip through the connecting shaft (376), so that the air blowing nozzle (375) tilts upward and displaces, flexibly adjusting the air blowing position and angle to blow dry the dead corner position at the end of the lens body (1). After the air bags (25) contract, the limiting spring (373) rebounds to drive the abutting plate (372) to return to its position, and the torsion spring (3761) makes the linkage bent plate (374) and the air blowing nozzle (375) return to their positions. This process is repeated to improve the drying efficiency.
