Description

Technical Field

[0001] The invention relates to the field of medical devices, in particular to a protective film cover for a medical soft lens. Background Art

[0002] Medical endoscopes include gastroscopes, colonoscopes, bronchoscopes, urinary endoscopes, choledochoscopes, etc., which play a very important role in minimally invasive medical examinations and treatments. Currently, clinical medical soft endoscopes must be washed with water, enzyme washed, dried, and sterilized before they can be used again. This process not only damages the soft endoscope, but also greatly reduces the efficiency of its use. Incomplete sterilization can also lead to cross infection.

[0003] There is no mature, low-cost protective cover for medical soft lenses in clinical practice, which can reduce the frequency of disinfection and sterilization of medical soft lenses, improve the efficiency of their use, and prevent cross infection. Summary of the invention

Pressing the operating arm causes the rotating arm to rotate so that the fixing arm leaves the head side extension line of the inner cavity of the fixing port.

[0013] A plurality of reinforcing stems are arranged along the long axis of the inner wall of the membrane sleeve.

[0014] The outer side of the membrane sleeve is connected in parallel with an isolated operating membrane sleeve, and the tail of the operating membrane sleeve is connected with an operating inlet.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Medical soft endoscopes are of great significance in human cavity inspection and minimally invasive surgery. Their structure includes a long soft video cable at the head and a display screen at the tail. After using the medical soft endoscope, the video cable needs to be strictly sterilized, but the video cable has a narrow operating cavity, which often leads to incomplete sterilization and even serious cross-infection.

[0041] The protective film sleeve for the medical soft endoscope of the present invention comprises a fixed port 1, a soft film sleeve 2 and a video head protection barrel 3 which are sealed and connected in sequence from the tail end to the head end. The fixed port 1 is the entrance for inserting the video cable of the medical soft endoscope, and the tail opening is larger than the cross section of the video cable, and is preferably set to a trumpet shape to facilitate the insertion of the video cable. The film sleeve 2 is the outer sleeve of the video cable, and the inner cavity of the film sleeve 2 is slightly larger than the cross section of the video cable. The video cable can be smoothly inserted into the film sleeve 2, but no excess will be formed. The video head protection barrel 3 is a barrel-shaped structure with a blind end at one end, which is used to adapt to the camera mounted on the head end of the video cable to protect the video head of the medical soft endoscope. The fixed port 1, the soft membrane sleeve 2 and the video head protection barrel 3 are sealed and connected in sequence to form a sleeve-like structure with a blind head end and an open tail end, which is adapted to be mounted on the medical soft mirror video cable to isolate the video cable inserted into the human cavity and the inner wall of the human cavity to avoid cross infection; at the same time, when it is used again, there is no need to clean and sterilize the medical soft mirror video cable to avoid damage to the cleaning and sterilization of the medical soft mirror video cable; at the same time, after the use of the medical soft mirror, it only needs to be replaced with a new sterile medical soft mirror protective film cover and it can be used again, which greatly improves the use efficiency of the medical soft mirror.

[0042] The fixed port 1 is cylindrical, made of elastic hard material, and has a fixed shape. The tail is the entrance 11 for the soft endoscope video cable, and the tail is preferably set as a trumpet mouth, which is convenient for the head end of the video cable to enter the fixed port 1, and then enter the film sleeve 2 in turn, and finally enter the video head protection barrel 3 and be relatively fixed with the video head protection barrel 3. A fixing mechanism is set on the fixed port 1. When the medical soft endoscope video cable enters the appropriate position in the medical soft endoscope protective film sleeve, the fixing mechanism temporarily fixes the fixed port 1 on the handheld side of the medical endoscope video cable, so that the medical soft endoscope protective film sleeve and the video cable are relatively fixed, avoiding the displacement of the video head protection barrel 3 and the video head at the head end of the video cable during operation, which affects the video acquisition. There are many specific embodiments of the fixing mechanism, which will be described in detail later.

[0043] The membrane sleeve 2 is a tubular membrane of super-smooth medical materials, including polyvinyl chloride (PVC), polyvinyl alcohol (PVA), silicone rubber, etc. The significance of super-smooth materials is to reduce friction resistance when inserting the medical soft endoscope video cable, making it easier to insert the video cable. The inner diameter of the membrane sleeve 2 is larger than the outer diameter of the corresponding medical soft endoscope video cable, and the difference is less than 1mm, so that the video cable can be easily inserted; at the same time, it will not form too much surplus outside the video cable and occupy too much space; especially when used in the respiratory tract, it will avoid occupying the respiratory cavity and affecting respiratory ventilation.

[0044] For the same reason, the membrane sleeve 2 preferably has a wall thickness of less than 0.15mm, which can not only avoid the lack of strength and easy damage, but also ensure that the membrane sleeve 2 is placed on the medical soft mirror to affect the bending and deformation ability of the video cable, and enter the operation of the medical soft mirror. The cross-sectional circumference of the membrane sleeve 2 is 6-32mm, and the length is 120-1600mm. Different medical soft mirrors correspond to different outer diameter video cables. The length should meet the use requirements of different clinical use scenarios and be greater than the length required for insertion into the body cavity during specific use.

[0045] The video head protection barrel 3 is set to be a barrel shape that matches the medical soft mirror. It is a hard elastic material with a circular cross-section that is slightly larger than the soft mirror video head. It can be tightly mounted outside the soft mirror video head, and the transparent blind end on the head side forms a video head light-transmitting protection sheet 31. A thicker medical soft mirror video head needs to be adapted to a thicker video head protection barrel 3. When in use, the video head protection barrel 3 is tightly mounted on the medical soft mirror video head, which can not only prevent the video head protection barrel 3 from moving between the video head and the video head, but also ensure that the video head light-transmitting protection sheet 31 can be tightly attached to the front of the soft mirror video head, ensuring the quality of video acquisition and reliable cleaning. Furthermore, the light transmittance of the video head light-transmitting protection sheet 31 is greater than 85%. The higher the light transmittance, the better. A light transmittance greater than 85% can meet most clinical needs.

[0046] Further, such as Figure 1 As shown, the fixing mechanism includes an elastic ring 12-1, and the inner diameter of the elastic ring 12-1 in a natural state is smaller than the outer diameter of the corresponding medical soft mirror. Figure 1 As shown in the left figure, the elastic ring 12-1 can be connected to the fixed mouth 1 and placed outside the film sleeve 2 before the package is opened. The film sleeve 2 is compressed and deformed, but the airtightness of the film sleeve 2 is not affected; at the same time, the elastic ring 12-1 relaxes naturally, which does not affect its elasticity and service life; before use, it is flipped and placed outside the head end of the fixed mouth 1, so that the film sleeve 2 no longer compresses the film sleeve 2, so that the soft lens video cable can be smoothly inserted into the film sleeve 2; when the video cable enters the appropriate position of the medical soft lens protective film sleeve, the elastic ring 12-1 is flipped again so that its ring is sleeved outside the film sleeve 2 at the head end of the fixed mouth 1, and the elastic ring 12-1 presses the film sleeve 2 outside the soft lens video cable, so that the medical soft lens protective film and the video cable are fixed.

[0047] like Figure 1 As shown in the right figure, the elastic ring 12-1 can also be set separately and freely, and the front ring is used to be sleeved outside the fixing port 1. When the video cable enters the appropriate position of the medical soft lens protective film sleeve, the elastic ring 12-1 is pushed to the outside of the film sleeve 2 at the head end of the fixing port 1. The elastic ring 12-1 presses the film sleeve 2 outside the soft lens video cable, thereby fixing the medical soft lens protective film and the video cable.

[0048] like Figure 2 As shown, the fixing mechanism includes a through cylinder 12-2 that passes through the side wall of the fixing port 1, a flexible fixing rod 12-3 is movably arranged in the through cylinder 12-2, matching threads are arranged on the inner wall of the through cylinder 12-2 and the outer wall of the fixing rod 12-3, the length of the flexible fixing rod 12-3 is greater than the length of the through cylinder 12-2, and the outer diameter of the flexible fixing rod 12-3 and the inner diameter of the through cylinder 12-2 are interference fit.

[0049] like Figure 3 As shown, the fixing mechanism includes a fixing block 12-4 and an elastic ring 12-5 arranged on the side wall of the fixing port 1, and the elastic ring 12-5 is partially inserted into the fixing block 12-4. As shown in the figure, the elastic ring 12-5 can have two shapes, the elastic ring is partially directly connected and fixed to the fixing block 12-4, or the elastic ring 12-5 is provided with an extension part, and is connected and fixed to the fixing block 12-4 through the extension part. When in use, after the video cable enters the appropriate position of the medical soft lens protective film sleeve, the elastic ring 12-5 is repeatedly looped and fixed to any part of the soft lens handheld end (such as the display screen, the operation port, the hanging part, etc.), so that the medical soft lens protective film and the video cable are fixed.

[0050] like Figure 4As shown, the fixing mechanism includes a rotating arm arranged on the side wall of the fixed port 1, and the middle part of the rotating arm is fixed to the rotating axis of the side wall of the fixed port 1; the fixed arm 12-61 on the head side of the rotating arm extends out of the head side of the fixed port 1 and intersects with the head side extension line of the inner cavity of the fixed port 1; the operating arm 12-62 on the tail side of the rotating arm is separated from the outer wall of the fixed port 1; the operating arm 12-62 is pressed, and the rotating arm rotates to make the fixed arm 12-61 leave the head side extension line of the inner cavity of the fixed port 1. A compression elastic mechanism, such as a spring, is arranged between the operating arm 12-62 and the side wall of the fixed port 1; under the elastic force of the spring, the fixed arm 12-61 intersects with the head side extension line of the inner cavity of the fixed port 1, and the film sleeve 2 at this position is deflected away. Before use, press the operating arm 12-62 to make the fixed arm 12-61 leave the head side extension line of the inner cavity of the fixed port 1 and no longer occupy the film sleeve 2, so that the video cable can smoothly enter the protective film sleeve of the medical soft lens. When the video cable enters the appropriate position of the medical soft lens protective film sleeve, release the operating arm 12-62 to reset the fixed arm 12-61, and the fixed arm 12-61 presses the outside of the film sleeve 2 on the head side of the soft lens video cable of the fixed port 1, thereby fixing the medical soft lens protective film and the video cable.

[0051] Further, such as Figure 5 The figure is a schematic cross-sectional view of a plurality of reinforcing stems 21 arranged along the long axis of the inner wall of the film sleeve 2. The purpose of providing the reinforcing stems 21 is that when the medical flexible lenticular cable is inserted into the film sleeve 2, the reinforcing stems 21 can form a support between the inner wall of the film sleeve 2 and the outer wall of the medical flexible lenticular cable, so as to facilitate the gas to enter the film sleeve 2 when the medical flexible lenticular cable is inserted, or the gas in the film sleeve 2 to be discharged.

[0052] Further, such as Figure 6 As shown, the outer side of the membrane sleeve 2 is connected and isolated with an operating membrane sleeve 22, and the tail of the operating membrane sleeve 22 is connected with an operating insertion port 22-1. The purpose of setting the operating membrane sleeve 22 is to facilitate the insertion of various cable-shaped operating instruments through the operating membrane sleeve 22, so as to facilitate the implementation of specific operations during medical soft endoscope examination or treatment, such as: inserting biopsy forceps for inspection, inserting suction tubes to attract secretions, inserting throwing knives to cut tumors, inserting hemostatic clips to stop bleeding, etc. When there is no operation, the operating membrane sleeve 22 is not opened, but only two layers of film, which occupies very little space in the body cavity. Of course, it is needless to say that the wall thickness of the operating membrane sleeve 22 should be less than 0.15mm, and soft medical materials can be selected, which are the same as the materials of the membrane sleeve 2. The tail of the operating film cylinder 22 is connected to an operating inlet 22-1 for inserting a cable-shaped operating device; the operating inlet 22-1 preferably matches the injection port of a syringe. When the video head light-transmitting protective sheet 31 is contaminated by mucus during inspection, a syringe can be connected through the operating inlet 22-1 to rinse and clean the video head light-transmitting protective sheet 31 with physiological saline. The inner diameter of the operating film cylinder 22 preferably matches the common cable-shaped operating device and is less than 3 mm.

[0053] The opening at the head end of the operating film cylinder 22 is flush with the head end of the operating film cylinder 22, so that after the operating instrument is inserted, it just extends out from the end of the soft mirror video head and is just visible, which is convenient for inserting the instrument operation; or it is located at the tail side of the head end of the operating film cylinder 22, no more than 20 mm away from the opening at the head end of the film cylinder 22, which can also play the above role.

[0054] Furthermore, the video head protection barrel 3 includes an integrally formed barrel structure, the inner cavity of the barrel structure matches the thickness of the video head at the end of the corresponding medical soft endoscope video cable head, and can be looped around the video head and temporarily fixed. The integrally formed video head protection barrel 3 includes polycarbonate PC, ethylene-tetrafluoroethylene copolymer ETFE and optical grade polyester film PTE, which are all commonly used medical materials with high light transmittance, which can ensure the video quality of the video head at the end of the soft endoscope video cable head to the treatment site.

[0055] Furthermore, the side wall of the video head protection barrel 3 is provided with a plurality of depressions toward the central axis along the long axis; or, the inner wall of the video head protection barrel 3 is provided with a plurality of convex points. Regardless of the depressions or convex points, the functions are the same. When the video head protection barrel 3 is placed on the soft lens video cable video head, the depressions or convex points can be deformed and supported on the outer wall of the video head, thereby strengthening the fixing effect of the video head protection barrel 3 and the soft lens video cable video head, and can also form a gap between the outer wall of the video head and the inner wall of the video head protection barrel 3, providing a gas passage, facilitating the discharge of gas in the video head protection barrel 3, and facilitating the placement of the video cable video head into the inner end position of the video head protection barrel 3.

[0056] Further, such as Figure 7 As shown, the video head protection barrel 3 includes a barrel body 32 and a barrel bottom 33, and the barrel bottom 33 includes a sealed cylindrical tube 34 and a video head light-transmitting protective sheet 31 located at one end of the cylindrical tube 34; the inner cavity of the cylindrical tube 34 matches the shape of the barrel body 32, and the video head light-transmitting protective sheet 31 includes optical glass, PC and ETFE. The advantage of this split structure is that it will not form a gas obstruction when inserted. It should be noted that the head end of the barrel body 32 is slightly closed to prevent the soft lens video cable from extending out of the barrel body 32. When the head end of the soft lens video cable is held to the closed part of the head end of the barrel body 32, the cylindrical tube 34 of the barrel bottom 33 is tightly mounted on the front of the barrel body 32, so that the video head light-transmitting protective sheet 31 is tightly fitted on the video head at the head end of the video cable, and the interface completes the position matching and relative fixation of the video head protection barrel 3 and the video cable video head.

[0057] Further, such as Figure 8 The protective film cover for the medical soft mirror further includes a screen protection bag 4, which is connected to the fixing port 1 and is wrapped around the display screen of the medical soft mirror. After the screen protection bag 4 is provided, the entire medical soft mirror can be protected, thereby achieving a better protective effect and reducing the potential risk of cross infection caused by contact with the display screen.

[0058] Furthermore, the inner wall of the film sleeve 2 is coated with a medical lubricant. The medical lubricant can reduce the friction when the flexible lenticular cable is inserted into the film sleeve 2, so that the flexible lenticular cable can be smoothly inserted into the film sleeve 2. The medical lubricant includes paraffin oil, silicone oil, etc. The specific ingredients include one or more of xanthan gum, glycerin, normal alkanes, siloxanes, glycerol, PVP substances and purified water.

[0059] The present invention also includes a medical soft mirror, wherein a handle fixing mechanism 51 is provided at the hand-held handle of the medical soft mirror, and the handle fixing mechanism 51 is adapted and temporarily fixed to the fixing mechanism at the tail of the fixing port 1. The video head of the medical soft mirror is provided with a video head fixing mechanism 52, and correspondingly, a barrel fixing mechanism 35 is provided on the inner wall of the video head protection barrel 3, and the video head fixing mechanism 52 is adapted and temporarily fixed to the barrel fixing mechanism 35.

[0060] Specifically, Fig. 9 As shown, the inner cavity of the fixing port 1 matches the shape of the medical soft mirror hand-held handle, and the handle fixing mechanism 51 is set as a convex block smaller than the bayonet 12-7 to form the handle fixing mechanism 51; correspondingly, the tail of the fixing port 1 is provided with an adapted bayonet 12-7 to form a fixing mechanism at the tail of the fixing port 1. A crack with a length exceeding the position of the bayonet 12-7 is set on both sides of the bayonet 12-7. When the medical soft mirror hand-held handle is clamped into the fixing port 1, the part between the two cracks is elastically tilted to raise the position of the bayonet 12-7. When the bayonet 12-7 corresponds to the handle fixing mechanism 51 formed by the convex block, the elastic tilted part is reset to make the bayonet 12-7 clamped outside the convex block, that is, outside the handle fixing mechanism 51, so that the fixing port 1 and the medical soft mirror hand-held handle are fixed. A raised detachment handle 12-8 is provided at the free end between the two cracks. When it is necessary to detach the fixing port 1 from the medical soft mirror hand handle, the detachment handle 12-8 can be pushed to lift the bayonet 12-7, thereby withdrawing the bayonet 12-7 from the handle fixing mechanism 51 formed by the protrusion, and then detaching the fixing port 1 from the medical soft mirror hand handle.

[0061] The present invention further comprises a storage sleeve 6, such as Fig.10 As shown, the storage sleeve is provided with a deformed depression 61 at the tail side of the corresponding film sleeve 2 adjacent to the video head protection barrel 3, and the distance of the narrow part of the deformed depression 61 is smaller than the outer diameter of the video head protection barrel 3. After the deformation depression 61 is expanded, the inner cavity allows the video head protection barrel 3 to pass through. Correspondingly, the storage sleeve 6 is provided with a connecting and fixing part 62 at the corresponding part of the fixing port 1, and the fixing port 1 is temporarily connected and fixed with the connecting and fixing part 62.

[0062] Specifically, the sleeve 6 is the outer packaging of the protective film sleeve of the medical soft endoscope, and is also provided with a sleeve cover to form a seal on the inner cavity of the sleeve 6 to ensure its sterile supply. The sleeve 6 is made of an elastic material with a certain strength. Through the deformation and depression 61 expansion, the video head protection barrel 3 is inserted into the head space of the sleeve 6 beyond the position of the deformation and depression 61. After insertion, the deformation and depression 61 is elastically reset to restore the narrow cavity state. The corresponding film sleeve 2 is compressed and accommodated in the deformation and depression 61, and the cross-section of the video head protection barrel 3 is larger than the narrow cavity of the deformation and depression 61 and is relatively fixed to the inner cavity of the sleeve 6 on the head side of the deformation and depression 61; in this way, under the joint action of the connection and fixing part 62 and the fixing port 1, the film sleeve 2 is prevented from curling to a certain extent, and its inner cavity is kept dilated, which is convenient for the insertion of the soft endoscope video cable. When it is necessary to remove the protective film cover of the medical soft mirror, apply pressure to the raised side wall of the deformed depression 61 (in the direction of the two arrows in the figure) to expand the inner cavity to be larger than the cross section of the video head protection barrel 3, allowing the video head protection barrel 3 to pass through. In some usage scenarios, such as lung transplantation, it is necessary to use a bronchoscope multiple times to examine the patient's trachea and bronchi. During breaks in use, the bronchoscope covered with the protective film cover of the medical soft mirror can be placed in the sleeve 6 and relatively fixed to prevent the protective film cover of the medical soft mirror from being contaminated by the external medical environment during breaks in use.

[0063] At the same time, the number of bronchoscopes in most clinical anesthesia departments is seriously insufficient. When lung isolation is required for lung surgery, the actual use time is not long, only 3-5 minutes, but it is difficult to sterilize in time for multiple patients. Some hospitals only wipe them with simple and practical disinfectants when they are urgently needed and use them again for other patients, causing hidden dangers of cross infection. After the above-mentioned sleeve 6 is set, the bronchoscope with the medical soft mirror protective film sleeve can be inserted into the sleeve 6 again after use, and the bronchoscope can be taken out and the medical soft mirror protective film sleeve can be stored in the sleeve 6, so that the bronchoscope can be used by other patients. Covering the tube cover can ensure that the medical soft mirror protective film sleeve is not contaminated by the external environment. When the patient needs to use the bronchoscope again during surgery, the bronchoscope is retrieved and the medical soft mirror protective film sleeve stored in the sleeve 6 is re-inserted, and it can be used again. In this way, a bronchoscope can be used by multiple patients at the same time and cross infection can be avoided.
