Description

Disinfection-free cystoscope, reusable urological flexible scope kit and disposable flexible scope housing TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a disinfection-free cystoscope, a reusable urological flexible scope kit and a disposable flexible scope housing. BACKGROUND

[0002] Cystoscopy is an important means of diagnosing diseases in urology, and plays an irreplaceable role in the diagnosis of bladder and urethral diseases. Cystoscopes mainly include bladder hard scopes and bladder soft scopes. Traditional bladder hard scopes are made of metal, which causes certain damage to the urethral mucosa when entering the urethra, such as bleeding and pain. Moreover, they are not flexible, and for male patients, the urethra is long, and insertion has to go through two physiological bends and the urethral sphincter, which is extremely painful, and there is a blind area in the examination, which is easy to miss important lesions. Bladder soft scopes are flexible and can be bent, have a small tube diameter, cause little damage to the urethral mucosa, and have a clear field of view, so there is no blind area in the examination, which can meet the clinical needs and is acceptable to doctors and patients. At present, bladder soft scopes are more commonly used in clinical applications.

[0003] The internal structure of a bladder soft scope is complex, contains various components, is a precision instrument, and is expensive. For a bladder soft scope that can be reused after disinfection, due to the complex structure, multiple disinfection procedures, complicated disinfection steps, and long disinfection cycle, the disinfection cost is high, and disinfection is not thorough, which easily causes cross-infection. In addition, repeated disinfection affects the service life of the cystoscope, and once a fault occurs, the repair cost is high. For disposable bladder soft scopes, after use, they are discarded, and there is no possibility of disinfection and cross-infection, but because they contain various precision components, they are expensive, and complete disposal causes resource waste and increases the medical cost of patients.

[0004] Therefore, there is an urgent need to improve the existing bladder soft scope to reduce costs and meet the needs of bladder scopes with a large application volume and improve surgical efficiency.

[0005] Flexible scopes provide imaging, illumination, and an operating channel, are flexible, easy to enter the natural passageway of the human body, and easy to stretch into dead corner positions, and are used in many aspects of clinical examination, diagnosis, surgery, treatment, etc.

[0006] Endoscope is a common tool for surgery, which needs to ensure a sterile environment during use, and needs to be sterilized before and after use. However, the endoscope contains high-precision components such as optical fibers and camera components, and needs to be bent. The sterilization procedure is complex, the sterilization time is long, the cost is high, and the sterilization is not thorough, which can cause cross infection between patients. In addition, sterilization can also damage the components, causing expensive endoscopes to be damaged. Long sterilization time leads to non-continuous use, long waiting time between two operations, which is not conducive to the current continuous operation.

[0007] Therefore, it is urgent to solve the current endoscope sterilization problem, especially the soft mirror, so that it can be better applied to the diagnosis and treatment of diseases and meet more clinical needs.

[0050] Referring to FIGS. 1 to 8, a disinfection-free cystoscope according to a preferred embodiment of the present disclosure is shown. In the present embodiment, the disinfection-free cystoscope includes a bendable scope 10 and a housing 20 which is detachably sleeved on the outside of the bendable scope 10 to protect the bendable scope 10 from being contaminated during application to cystoscopy. The housing 20 is disposable and can be discarded after use. Since the bendable scope 10 is sealed inside the housing 20 during application, the bendable scope 10 and the housing 20 are separated after use, and the bendable scope 10 does not need to be disinfected or cleaned and can be directly reused by sleeving a new or unused housing 20. The bendable scope 10 is enclosed in the housing 20 to isolate the external environment.

[0051] The bendable scope 10 includes a control body 11 and an operation body 12, wherein the operation body 12 is connected to the rear end of the control body 11. The operation body 12 can be integrally formed with the control body 11 or separately manufactured. The size of the operation body 12 is larger than that of the control body 11, which can facilitate operation and make the size of the control body 11 smaller to facilitate smoother insertion into the human body.

[0052] The control body 11 has a body channel 110, and the operation body 12 has an operation channel, the body channel 110 is communicated with the operation channel, so as to install optical fiber or guide wire, and also can save material and reduce cost under the condition of ensuring hardness requirement.

[0053] The control body 11 includes a mounting end 111, a control section 112 and a body section 113, wherein the mounting end 111 is arranged at the top end of the control section 112, one end of the body section 113 is connected to the rear end of the control section 112, and the other end of the body section 113 is connected to the operation body 12, that is, the body section 113 is longitudinally connected between the control section 112 and the operation body 12. The mounting end 111 is a solid structure, and the hollow pipes in the control section 112 and the body section 113 together form the body channel 110, wherein the mounting end 111 arranged at the top end of the control section 112 closes the body channel 110 at the top end of the control section 112.

[0054] The control section 112 adopts the structure of snake bone or spring, and the bending angle can be controlled artificially or mechanically, so as to be more consistent with human physiological structure and better inserted into human body to perform corresponding operation. The body section 113 is not bendable, so as to ensure the overall strength of the bendable mirror body 10, which can better work and prolong service life.

[0055] The bendable mirror body 10 further includes at least one illumination element 13 and one imaging element 14, the illumination element 13 and the imaging element 14 are arranged independently and spaced apart from each other in the mounting end 111, that is, the illumination element 13 and the imaging element 14 are both located at the front end of the control body 11, when the control body 11 is applied in the surgical process, the illumination element 13 and the imaging element 14 provide illumination and imaging, and dynamically feedback the situation of the surgical position in real time, so that the operator can clearly observe the situation of the surgical position, and better perform the surgery under the visual condition. The imaging element 14 can be implemented as electronic mirror or fiber mirror.

[0056] As shown in FIG. 4, in the embodiment, in order to better achieve better illumination effect, the number of the illumination element 13 is implemented as two, and the cross section of the mounting end 111 is implemented as circular, and can also be implemented as oval. The two illumination elements 13 are symmetrically arranged on both sides of the mounting end 111, and the imaging element 14 is arranged in the middle of the mounting end 111, located in the middle of the two illumination elements 13.

[0057] The lighting element 13 can provide light so that the surgical position is illuminated, and the imaging element 14 can image the surgical position illuminated by the lighting element 13 under the action of the imaging element 14 to present a clear surgical field to the operator, facilitating the operator to perform surgical operations under visual conditions, etc.

[0058] In the embodiment, the lighting element 13 can be implemented as an optical fiber, as shown in FIG. 3, wherein the optical fiber is mounted to the mounting end 111 through the mounting channel arranged on both sides of the main body channel 110, thereby providing bright light, and the optical fiber can also be mounted through the main body channel 110, sharing a channel with the connecting line of the imaging element 14. In addition, the lighting element 13 can also be implemented as other lighting tools, such as LED lights, etc., and the wires are mounted through the main body channel 110, or the wires are embedded in the pipe wall or the lighting is implemented wirelessly, in which case the mounting channel is not needed. That is, the main body channel 110 provides a mounting and connecting channel for the lighting element 13 and the imaging element 14, so that the lighting element 13 and the imaging element 14 can work normally.

[0059] The mounting end 111 is adapted to be integrally formed with the control section 112, wherein the top end of the control section 112 is connected to the mounting end 111, and the main body channel 110 can be closed at the front end of the control body 11, that is, the mounting end 111 can be a round or oval plate shape, matched with the shape of the top end of the control section 112, and then the main body channel 110 is closed, wherein the lighting element 13 and the imaging element 14 are mounted to the front end of the control section 112 through the mounting end 111.

[0060] It is worth mentioning that, as shown in FIG. 2, the control section 112 is implemented as a snake bone structure, which can be bent within a certain angle range to better pass through the physiological bending part of the human urethra. The bending degree and bending direction of the control section 112 are adapted to be adjusted, and the control section 112 is bent in different directions through operation to better enter the human body. The bending of the control section 112 drives the bending of the outer shell 20, thereby enabling the bendable mirror body 10 and the outer shell 20 to enter the human body under visual and active bending conditions.

[0061] As shown in FIG. 1 and FIG. 3, the bendable mirror body 10 further comprises an adjusting unit 15, which comprises at least one adjusting wire 151 and an adjusting member 152, the adjusting member 152 is installed on the operating body 12, one end of the adjusting wire 151 is connected to the adjusting member 152, then extends along the installation channel to the top end of the control section 112, then is connected to the connection between the top end of the control section 112 and the installation end 111, or is connected to the installation end 111. By adjusting the adjusting member 152, the length of the adjusting wire 151 is adjusted, and in the process of stretching and retracting, the adjusting wire 151 will pull the control head end 1121 to move, thereby controlling the bending of the control section 112.

[0062] In this embodiment, the number of adjusting wires 151 is two, which are symmetrically connected to the two sides of the control section 112 respectively, so as to pull the control section 112 from different directions, thereby making the control section 112 bend in different directions and the bending angle adjustable.

[0063] In this embodiment, the adjusting member 152 can be a dial or a button, which can adjust the length of the adjusting wire 151 and is convenient to operate.

[0064] It is worth mentioning that the adjusting wire 151 can also be installed on the body channel 110 and connected to the top end of the control section 112 after passing through the body channel 110. In this way, it is convenient for later maintenance and replacement of the adjusting wire, which is beneficial to save costs.

[0065] As shown in FIG. 3 and FIG. 4, according to an embodiment of the present application, the installation end 111 comprises two partition members 1111, which are installed between the illumination element 13 and the imaging element 14 to separate the illumination element 13 and the imaging element 14, so that the two illumination elements 13 and the imaging element 14 are located in different areas.

[0066] The partition 1111 is made of light-proof material, and the height of the partition 1111 protruding from the plane of the mounting end 111 is about 0.1 mm. The partition 1111 can be integrally formed with the mounting end 111, or the partition 1111 extends forward from the top end of the mounting end 111, or the front end of the mounting end 1111 forms three grooves, respectively mounting two illumination elements 13 and one imaging element 14, so that the mounting end 111 forms two illumination areas and one imaging area to respectively mount two illumination elements 13 and the imaging element 14. The light-proof partition 1111 prevents the light of the illumination element 13 from shining on the imaging element 14, so that the existence of the illumination element 13 in the same plane as the imaging element 14 does not affect the imaging of the imaging element 14, and can be illuminated forward, so that the area to be fed back by the imaging element 14 is illuminated, facilitating the imaging element 14 to present a clear surgical field to the operator for clear observation of the surgical position.

[0067] It is worth mentioning that the imaging element 14 can be implemented to include a CMOS photosensitive chip 141 and a protective lens 142, wherein the protective lens 142 is installed in front of the CMOS photosensitive chip 141 to protect the CMOS photosensitive chip 141. The CMOS can be wireless or wired. If wired, the wire is installed through the main body channel 110.

[0068] As shown in FIG. 5, according to another embodiment of the present application, the mounting end 111A in the above embodiment is deformed. In this embodiment, the mounting end 111A has a groove 1112A and a protrusion 1113A. The groove 1112A is arranged at the middle of the mounting end 111, and the protrusion 1113A is two independent semicircular protrusions symmetrically located on both sides of the groove 1112A. Those skilled in the art can understand that the protrusion 1113A can also be circular around the groove 1112A. That is, the middle of the mounting end 111A is recessed inward to form the groove 1112A, and the un-recessed part around the mounting end 111A forms the protrusion 1113A in whole or in symmetric part. The plane where the protrusion 1113A is located is in front of the plane where the groove 1112A is located. And the protrusion 1113A is inclined, maintaining an angle with the end face of the groove 1112A to prevent blocking the imaging of the front end by the imaging element 14.

[0069] The illumination element 13 is mounted on the protrusion 1113A, and the imaging element 14 is mounted on the recess 1112A, so that the illumination element 13 is in front of the imaging element 14, providing bright light for the area to be imaged by the imaging element 14, so as to clearly image. At the same time, since the illumination element 13 is in front of the imaging element 14, the light of the illumination element 13 will not shine on the imaging element 14, so as not to interfere with the imaging of the imaging element 14.

[0070] Referring to FIG. 1, FIG. 6 to FIG. 8, according to an embodiment of the present application, the outer housing 20 comprises a housing 21, the housing 21 comprises a housing front section 211 and a housing rear section 212, wherein the housing rear section 212 is longitudinally connected to the rear of the housing front section 211, and the two are suitable for integrally formed manufacturing, the length of the housing front section 211 matches the length of the control body 11, and the length and shape of the housing rear section 212 match the length and shape of the operation body 12, so that the bendable mirror body 10 can be detachably mounted on the outer housing 20.

[0071] The outer housing 20 has a visual channel 22 and a working channel 23, which are independently arranged in the housing 21. The bendable mirror body 10 is mounted in the visual channel 22, and the relevant surgical instruments are inserted through the working channel 23 to perform corresponding operations. In addition, the perfusion fluid is also perfused into the body through the working channel 23, so that the working channel 23 is a channel shared by the perfusion fluid and the instruments, and the visual channel 22 is used to mount the bendable mirror body 10 to provide illumination and imaging for operation under visual conditions.

[0072] The front end of the visual channel 22 is provided with a protection piece 221, so that the front end of the visual channel 22 forms a closed end, and the bendable mirror body 10 cannot penetrate the visual channel 22. The protection piece 221 is suitable for being integrally formed with the housing 21, and the top end of the visual channel 22 is closed, so that the visual channel 22 forms a channel with a closed front end and an open rear end, so as to facilitate the insertion of the bendable mirror body 10 from the rear end to the front end. When it needs to be separated, the bendable mirror body 10 is pulled out from the rear end or peeled off by damaging the housing 21 to take out the bendable mirror body 10.

[0073] When the bendable mirror body 10 is installed inside the visual channel 22, the mounting end 111 reaches the inner side of the protector 221, so that the protector 221 closely adheres to the mounting end 111 to seal the bendable mirror body 10 in the visual channel 22, and the bendable mirror body 10 does not contact the external environment or the patient or the operator during the application of the non-sterilization cystoscope, and thus is not contaminated during the whole process from installation to application to disassembly. Therefore, after the bendable mirror body 10 is separated from the outer shell 20, it does not need to be sterilized and can be installed in a new outer shell 20 for the next operation. Without the sterilization process, the sterilization time is saved, the patient's waiting time is shortened, the efficiency is improved, and the cost is saved. At the same time, the outer shell 20 with simple material and structure is discarded, and the bendable mirror body 10 with precise components is reused, effectively saving the cost.

[0074] The front end and the rear end of the working channel 23 are both open, that is, the working channel 23 is a channel open at both ends, which facilitates the entry of instruments from the rear end and the extension of the instruments from the front end to perform corresponding operations, meeting the clinical needs.

[0075] The shell 21 has a certain toughness and elasticity, and the length of the shell front section 211 is slightly shorter than the length of the control section 112. When the bendable mirror body 10 is sleeved inside the shell 21, the protector 221 can be closely adhered to the mounting end 111 at the front end of the control section 112 under the elastic action of the shell 21, and the shell 21 can be closely adhered to the outer wall of the bendable mirror body 10 to prevent air bubbles and air from entering during bending, and the elastic shell does not affect the bending of the control section 112.

[0076] In this embodiment, the shell front section 211 is soft and bendable, facilitating the sleeving on the outside of the control body 11, and the shell rear section 212 is relatively hard and has a certain supporting effect, facilitating the installation of the control body 10 and the disassembly and handheld operation. The inner and outer surfaces of the shell 21 have a hydrophilic coating, which facilitates the entry into the human body and the installation and disassembly of the bendable mirror body 10.

[0077] The shell 21 can be made of transparent material or opaque material, but the protector 221 is made of transparent material, so that the protector 221 located in front of the illumination element 13 and the imaging element 14 does not affect the visualization effect.

[0078] The rear shell section 212 has a buckle 2121 and a mounting portion 2122, the buckle 2121 is arranged on the upper part of the rear shell section 212, the mounting portion 2122 is arranged on the middle part of the rear shell section 212, preferably the side part, wherein the mounting portion 2122 is matched with the adjusting member 152 in shape and size. When the bendable mirror 10 is mounted on the visual channel 22, the adjusting member 152 is adapted to pass through the mounting portion 2122 to be located inside the shell 21, and the adjusting member 152 is operated through the mounting portion 2122 to adjust the length of the control section 112.

[0079] It is worth mentioning that the mounting portion 2122 is closed, and the shell outside the mounting portion 2122 is integrally formed with the shell 21, which can not only accommodate the adjusting member 152, but also prevent external bacteria and dirt from entering the inside of the shell 21. That is, the inside of the entire shell 21 is a closed environment, so that the bendable mirror 10 located inside the shell maintains a sterile state.

[0080] The outer shell 20 further comprises a handle 24, the handle 24 is mounted on the rear shell section 212, the handle 24 is made of relatively hard material, wherein the handle 24 is mounted on the mounting portion 2122 and located outside the mounting portion 2122, when the adjusting member 152 is mounted inside the mounting portion 2122, the handle 24 can be sleeved outside the adjusting member 152 through the mounting portion 2122, and the adjusting member 152 can be actuated by rotating the handle 24.

[0081] Since the handle 24 is located outside the shell 21 and the mounting portion 2122 is closed, the adjusting member 152 can be adjusted by operating the handle 24. That is, the adjusting member 152 and the handle 24 rotate inside and outside the mounting portion 2122 respectively, and always maintain a closed state, so that the bendable mirror 10 located inside the shell 21 can not contact the patient and the operator.

[0082] That is, the handle 24 is connected to the adjusting member through the mounting portion 2122, and the rotation of the adjusting member 152 can be controlled by operating the handle 24, so as to adjust the length of the adjusting wire 151 and control the bending of the bendable mirror 10.

[0083] In this embodiment, the handle 24 can be implemented to be detached from the shell 21, but can still seal the shell 21 after installation.

[0084] The top of the operation body 12 has a clamping groove 120, which matches the buckle 2121. When the bendable mirror body 10 is installed in the visual channel 22, the buckle 2121 is connected with the clamping groove 120, so as to further fix the bendable mirror body 10 and the shell body 20, preventing the phenomenon of shaking or sliding during operation. And after the buckle 2121 and the clamping groove 120 are clamped, the rear connection of the shell body 20 and the bendable mirror body 10 is closed, ensuring the sterile state inside the shell 21.

[0085] The shell rear section 212 has a mounting port 2123, which is arranged at the rear end of the shell 21. The bendable mirror body 10 is adapted to be installed into the visual channel 23 through the mounting port 2123, and can also be extracted through the mounting port 2123.

[0086] It is worth mentioning that the size of the control body 11 is small, with a pipe diameter of about 3mm, so as to smoothly enter the urethra of the human body. The operation body 12 does not need to enter the urethra of the human body, so the size of the operation body 12 is larger than that of the control body 11. The shell rear section 212 also does not need to enter the human body, so the size of the shell rear section 212 is larger than that of the shell front section 211. The shape and size of the operation body 12 match the shape and size of the shell rear section 212, and the two can better fit each other to more smoothly insert into the urethra of the human body. The cross-sectional size of the shell front section 211 and the control body 11 is as small as possible, so as to more smoothly enter the urethra of the human body and not cause damage to the mucous membrane of the human body.

[0087] It is worth mentioning that the bendable mirror body 10 has a first positioning mark 16, and the shell body 20 has a second positioning mark 26. The first positioning mark 16 is longitudinally arranged on one side of the control body 11, and in this embodiment, it is arranged on the side where the adjusting part 152 is located. The second positioning mark 26 is arranged on the shell 21, and is preferably arranged at the rear end of the shell front section 211 or the connection between the shell rear section 212. It can also be used as a mark extending along the shell rear section 212 to the top end of the shell front section 211, and is located on the side where the mounting part 2122 is located.

[0088] Thus, when the bendable mirror body 10 is installed in the outer casing body 20, when the control body 11 enters the shell 21, the first positioning mark 16 is aligned with the second positioning mark 26, so that the control body 11 can enter the visual channel 22 according to the preset position, so that the operation body 12 is aligned with the rear shell section 212, and the buckle 2121 and the clamping groove 120 are directly aligned, without the need to adjust the control body 11. If alignment cannot be achieved during installation, the adjusting piece 152 is difficult to install in the mounting portion 2122, and the buckle 2121 and the clamping groove 120 are difficult to align, and then the position of the control body 11 in the visual channel 22 needs to be adjusted constantly when the buckle is engaged later. Due to the close fit between the two, unexpected situations during the adjustment process are avoided, so that the fitting of the two is smoother.

[0089] It is worth mentioning that the first positioning mark 16 is a linear mark, which is arranged along the control section 112 from the mounting end 111 and extends to the end of the main body section 113. That is, the first positioning mark 16 is longitudinally arranged on the entire control body 11. The second positioning mark 26 can be a point arranged at the end of the front shell section 211; or the second positioning mark can be a line arranged longitudinally on the front shell section 211, extending from the top end of the front shell section 211 to the connection between the end of the front shell section 211 and the rear shell section 212 or to the mounting portion 2122.

[0090] During the installation of the bendable mirror body 10 in the outer casing body 20, the operator can always observe the installation angle of the two, that is, as long as the front end of the first positioning mark 16 is aligned with the second positioning mark 26 at the beginning of the installation, and then the bendable mirror body 10 is pushed forward while the outer casing body 20 is pulled backward, so that the two are fitted together. During this fitting process, the second positioning mark 26 is always aligned with the first positioning mark 16 to prevent the installation from being inclined, and the second positioning mark 26 is always moved along the longer first positioning mark 16, so that the bendable mirror body 10 can be accurately installed in the outer casing body 20. After installation, the buckle 2121 is accurately aligned with the clamping groove 120, and the adjusting piece 151 can be aligned with the mounting portion 2122, without the need to twist back and forth during installation to adjust the angle to align the buckle 2121 and the clamping groove 120 and the adjusting piece 151 and the mounting portion 2122, saving time and effort, and facilitating accurate installation.

[0091] It is worth mentioning that the first positioning mark 16 and the second positioning mark 26 can not only be a mark line, but also contrast with the color of the bendable mirror body 10 and the shell body 20 to facilitate the distinction. The first positioning mark 16 and the second positioning mark 26 can also be set as a groove and a protrusion in shape to position in the clamped condition. Those skilled in the art can understand that the first positioning mark 16 and the second positioning mark 26 can also be set as other shapes to play a positioning role.

[0092] As shown in FIG. 7, according to one embodiment of the present application, the rear end of the shell body 20 has a certain hardness, the shell 21 outside the visual channel 22 and the working channel 23 has a certain toughness and elasticity, and the size of the visual channel 22 matches the size of the bendable mirror body 10, and the size of the working channel 23 matches the channel of the corresponding surgical instrument. When the bendable mirror body 10 and the surgical instrument are respectively installed into the visual channel 22 and the working channel 23 of the shell body 20, the bendable mirror body 10 can be closely attached to the shell 21, and the surgical instrument can freely move in the working channel 23. In order to reduce the size, the surgical instrument is attached to the shell as much as possible, but not completely attached to the extent that it is difficult to move, so as to facilitate the operation. Therefore, in this embodiment, the bendable mirror body 10 and the surgical instrument do not stretch the shell 21 to deformation.

[0093] In this embodiment, the non-disinfection cystoscope can be used in the application process. The bendable mirror body 10 is pre-installed into the visual channel 22, so that the bendable mirror body 10 forms an integral whole with the shell body 20, and then enters the urethra and bladder of the human body under visual conditions, and the surgical instrument is separably and movably placed into the urethra and bladder of the human body through the working channel 23 to perform corresponding operations.

[0094] Since the non-disinfection cystoscope enters the urethra and bladder of the human body under visual conditions and provides a working channel for the surgical instrument, in this embodiment, the shell body 20 plays a role of a guide sheath and can drive the bending of the non-disinfection cystoscope through the bending of the control section 111. Therefore, it is required that the shell 21 has a certain strength to retain the working channel 23 after being inserted into the human body to prevent the working channel 23 from being squeezed and deformed during the process of being inserted into the human body. The relatively hard shell 21 makes the working channel 23 always in a smooth state, so that the working channel 23 can be used for perfusion liquid, placement and extraction of the surgical instrument.

[0095] In the above embodiments, the front and rear of the shell 21 are made of different materials, the front end of the shell 21 is made of a material with flexibility, softness and elasticity, and the rear end is relatively hard and has a supporting effect. Those skilled in the art can understand that the shell 21 can also be implemented in a soft state at the front and rear, and is expanded by the bendable mirror body 10 for installation.

[0096] As shown in FIG. 8, according to one embodiment of the present application, in this embodiment, the shell 21B is relatively soft, the size of the visual channel 22B is small without external force, and the visual channel 22B can be expanded by the bendable mirror body 10 and then only fit the outside of the bendable mirror body 10. The working channel 23B can also be expanded by the surgical instrument to limit the movement of the surgical instrument. After the bendable mirror body 10 and the surgical instrument are respectively installed in the visual channel 22B and the working channel 23B, the shell 21B is expanded and deformed so that the front shell 211B is in an elliptical shape. That is, the bendable mirror body 10B and the surgical instrument are sleeved in the shell 21B by the elastic effect of the shell 21B, and then tightly fit the shell 21B.

[0097] In the application process, the bendable mirror body 10 and the surgical instrument are respectively installed in the visual channel 22B and the working channel 23B, so that the bendable mirror body 10, the surgical instrument and the outer shell 20B form an integral whole, and then are inserted into the urethra and bladder of the human body together. Since the surgical instrument tightly fits the shell 21B, the bendable mirror body 10 and the outer shell 20B are moved together during the movement of the surgical instrument, which does not affect the performance of the corresponding operation of the surgical instrument, and can make it operate under the condition of visualization.

[0098] It is worth mentioning that, for any of the above embodiments, the shell 21 / 21B is relatively smooth, and does not cause damage to the urethral mucosa and discomfort to the patient during insertion into the urethra and bladder of the human body.

[0099] In addition, as shown in FIG. 8, according to another embodiment of the present application, the clamping groove 120B is arranged at the rear side of the adjusting unit 15B and arranged in a ring around the operation body 12, and the clasp 2121B is arranged at the rear side of the mounting portion 2122B and arranged in a ring around the rear shell section 212B, so that the clasp 2121B is located between the mounting port 2123B and the mounting portion 2122B. The clamping groove 120B and the clasp 2121B are matched and detachably connected, so as to connect or separate the bendable mirror body 10 and the outer shell 20B. In this embodiment, only the lengths of the front end of the bendable mirror body 10 and the front end of the outer shell 21B need to be matched, and the positions of the clamping groove 120B and the clasp 2121B do not need to be specially aligned when sleeving. In addition, the clasp 2121B is arranged at a position close to the mounting port 2123B, i.e., at a position close to the end of the rear shell section 212B, so as to facilitate the clamping and separation of the bendable mirror body 10 and the outer shell 20B. That is, the clasp 2121B and the clamping groove 120B are both annular and arranged at the rear end of the rear shell section 212B and the operation body 12, respectively, and the clasp 2121B and the clamping groove 120B can be connected or separated from the rear end after sleeving. When separating, the clasp 2121B can be pressed.

[0100] Referring to FIG. 9, an aseptic cystoscope is provided according to another preferred embodiment of the present application. In this embodiment, the handle 24 is deformed. The aseptic cystoscope comprises a bendable mirror body 10C and an outer shell 20C, which is detachably sleeved on the outside of the bendable mirror body 10C, so as to protect the bendable mirror body 10C from being contaminated during the cystoscope operation and to avoid disinfection or cleaning. After the outer shell 20C is sleeved, a new or unused outer shell 20C can be directly used again, and the outer shell 20C is a disposable product without precise components and has low manufacturing cost and can be discarded after use.

[0101] The bendable mirror body 10C comprises a control body 11C and an operation body 12C, wherein the operation body 12C is integrally formed with the control body 11C and connected to the rear part of the control body 11C.

[0102] The control body 11C includes a control section 112C and a body section 113C, wherein one end of the body section 113C is connected to the rear end of the control section 112C, and the other end of the body section 113C is connected to the operation body 12C. The hollow pipe inside the control section 112C and the body section 113C together form the body channel, wherein the front end of the body channel is a closed structure.

[0103] The control section 112C adopts a snake bone or spring structure, and the bending direction and bending angle are adjusted by the adjusting unit 15C. As in the above embodiment, the adjusting unit 15C includes at least one adjusting wire 151C and an adjusting piece 152C, the adjusting piece 152C is installed on the operation body 12C, and one end of the adjusting wire 151C is connected to the adjusting piece 152C and then extends to the top end of the control section 112C. By adjusting the adjusting piece 152C, the length of the adjusting wire 151C is adjusted, and in the process of stretching and retracting, the adjusting wire 151C will pull the control section 112C to move, thereby controlling the bending of the control section 112C.

[0104] The first positioning mark 16C is arranged on the outside of the bendable mirror body 10C, and the second positioning mark 26C is arranged on the outside of the shell body 21C. When the two are installed, the first positioning mark 16C and the second positioning mark 26C correspond to each other, so as to accurately position the installation position of the two, and ensure that the installation is in place at one time.

[0105] The shell body 20C includes a shell 21C, which includes a shell front section 211C and a shell rear section 212C, which are suitable for one-piece manufacturing. The length of the shell front section 211C matches the length of the control body 11C, and the length and shape of the shell rear section 212C match the length and shape of the operation body 12C, so that the bendable mirror body 10C can be detachably installed on the shell body 20C.

[0106] The shell body 20C is the same as the shell body 20 of the above embodiment, and has a mounting port 2123C at the rear end. The bendable mirror body 10C is installed in the visual channel through the mounting port 2123C, and the installation method is the same as that of the above embodiment, which will not be described here.

[0107] The handle 24C is deformed in this embodiment. The handle 24C is arranged outside the rear end of the shell 21, and is suitable for being integrally formed with the rear shell section 212C. The handle 24C can rotate along the outside of the rear shell section 212C of the shell 21C. When the bendable scope 10C is installed inside the outer shell 20C, the handle 24C is located outside the adjusting member 152C. By rotating the handle, the rotation of the adjusting member 152C is driven, so that the bending of the control section 112C can be adjusted, and the sterile environment can be maintained.

[0108] Referring to FIGS. 10-12, a reusable urinary flexible scope kit according to a first preferred embodiment of the present application is shown. In this embodiment, the reusable urinary flexible scope kit includes a disposable flexible scope shell 610 and a reusable inner scope 620. The reusable inner scope 620 is sleeved in the disposable flexible scope shell 610, and the disposable flexible scope shell 610 protects the reusable inner scope 620 from being contaminated. During the entire operation of the human body, the reusable inner scope 620 is not in contact with the patient, medical staff and the external environment, and is sterile throughout the process. Therefore, after use, the reusable inner scope 620 does not need to be sterilized, and after being taken out of the disposable flexible scope shell 610, the disposable flexible scope shell 610 is discarded, and the reusable inner scope 620 can be directly sleeved in the next disposable flexible scope shell 610 for continuous use. In use, a plurality of disposable flexible scope shells 610 cooperate with the reusable inner scope 620, and the disposable flexible scope shell 610 is replaced after being used once.

[0109] The disposable flexible scope shell 610 is made of medical plastic material that can be applied to the human body, has low cost, and does not cause excessive economic burden to the patient after being used and discarded. Moreover, the disposable flexible scope shell 610 does not need to be sterilized, which not only saves sterilization cost, but also saves waiting time between operations, especially for continuous operations and outpatient operations that are inconvenient to sterilize and cannot completely guarantee sterile operation. The front end of the disposable flexible scope shell 610 is soft, and the rear end is hard. The disposable flexible scope shell 610 is easily sleeved outside the reusable inner scope 620, the front ends of the two are closely attached to each other to ensure sterility, and a holding part is provided to facilitate operation. The part of the reusable inner scope 620 that enters the human body does not need to be touched throughout the process, which facilitates the reuse of the reusable inner scope 620.

[0110] The disposable flexible scope shell 610 includes a shell body 611 and an operation end 612 connected to the rear end of the shell body 611. The shell body 611 is made of a material that has certain toughness, is soft, and is suitable for bending. The operation end 612 is made of a relatively hard material, provides a certain supporting effect to enable hand operation, and facilitates the installation and removal of the reusable inner scope 620.

[0111] The disposable soft scope shell 610 has a sleeve connection channel 6101 and an operation channel 6102, which are independently arranged inside the shell main body 611 and extend to the operation end 612. The front end of the sleeve connection channel 6101 is closed, which can ensure the sterile environment of the reusable endoscope body 620 when it is installed inside the sleeve connection channel 6101.

[0112] The disposable soft scope shell 610 also has a sleeve interface 6103 arranged at the rear end of the operation end 612 and connected to the sleeve connection channel 6101. That is, the sleeve connection channel 6101 extends from the front end of the shell main body 611 to the rear end of the operation end 612, and is connected to the outside through the sleeve interface 6103, so that the reusable endoscope body 620 can be installed in the sleeve connection channel 6101 through the sleeve interface 6103, providing visual operation for the reusable urinary soft scope kit.

[0113] The disposable soft scope shell 610 also has an operation channel inlet 6104 and an operation channel outlet 6105, which are respectively connected to the operation channel 6102 at the front end and the rear end of the operation channel 6102. The operation channel inlet 6104 is arranged at the connection between the shell main body 611 and the operation end 612, or at the side of the operation end 612, and the operation channel outlet 6105 is arranged at the front end of the shell main body 611. A surgical instrument is adapted to be detachably installed in the operation channel 6102 to perform corresponding surgical operations, and is also adapted to perfuse liquid through the operation channel 6102 to maintain intracavity pressure. The surgical instrument includes a lithotripsy optical fiber, a biopsy forceps, a foreign body forceps, a stone basket and other instruments needed in clinical surgery.

[0114] The operation end 612 includes an operation main body 6121 and an operation handle 6122 arranged outside the operation main body 6121. The operation main body 612 has a connection groove 6123, which is arranged inside the operation handle 6122 and connected to the sleeve connection channel 6101 and the sleeve interface 6103.

[0115] The operation end 612 further comprises a buckle arranged on the side of the operation body 6121 to facilitate clamping the repeatable endoscope 620. The buckle can be omitted, and the two can be directly attached, or a fixing member can be arranged at the rear end of the two to connect them. Therefore, those skilled in the art can understand that the connection mode between the rear end of the disposable soft scope shell 610 and the repeatable endoscope 620 is not limited by the above-mentioned enumeration.

[0116] The repeatable endoscope 620 comprises a bending section 621, a body section 622, and a control section 623, wherein the bending section 621 and the control section 623 are respectively connected to the front end and the rear end of the body section 622, and the control section 623 is adapted to control the bending angle and bending direction of the bending section 621.

[0117] The control section 623 comprises a control body 6231, which forms the rear end of the repeatable endoscope 620. The control body 6231 matches the operation body 6121, so that the outer wall of the control body 6231 is attached to the inner wall of the operation body 6121, and the rear end of the repeatable endoscope 620 and the disposable soft scope shell 610 are tightly connected.

[0118] The control section 623 further comprises a dial 6232 and at least one control line 6233, which is implemented as two control lines 6233 in this embodiment. The dial 6232 is mounted on the control body 6231, and the control line 6233 is connected between the dial 6232 and the front end of the bending section 621. The length of the control line 6233 is adjusted by the dial 6232 to control the bending direction and bending angle of the bending section 621.

[0119] The control section 623 can also have a clamping groove that matches the buckle described above. When the repeatable endoscope 620 is detachably mounted inside the sleeve connection channel 6101, the buckle and the clamping groove are matched and connected to connect the rear end of the repeatable endoscope 620 and the disposable soft scope shell 610, so as to facilitate one-handed operation, and the rear end of the two can be sealed to keep the repeatable endoscope 620 in a sterile environment during application. The two can also be connected by other means.

[0120] The knob 6232 is matched with the connecting groove 6123. When the reusable endoscope body 620 is sleeved in the disposable flexible scope shell 610, the knob 6232 is installed in the connecting groove 6123. The knob 6232 is rotated by operating the handle 6122, so as to adjust the bending of the bending section 621 of the reusable endoscope body 620. When the handle 6122 is located at different positions, the bending angle and bending direction of the bending section 621 are different. Refer to FIG. 10.

[0121] Since the operator contacts the handle 6122 from the outside of the disposable flexible scope shell 610 and controls the rotation of the knob 6232 by rotating the handle 6122, the operator does not contact the reusable endoscope body 620, so that the operator does not contact the reusable endoscope body 620 during the whole operation process, thereby preventing the reusable endoscope body 620 from being contaminated and ensuring the sterile environment of the reusable endoscope body 620.

[0122] In the embodiment, the bending section 621 is implemented in a snake structure, and the main body section 622 is implemented in a mesh structure. When the reusable endoscope body 620 is installed in the sleeving channel 6101 of the disposable flexible scope shell 610, the bending section 621 and the main body section 622 are tightly fitted with the operation body 6121. Due to the flexibility of the operation body 6121, the operation body 6121 can be bent along with the bending of the bending section 621.

[0123] Therefore, the reusable endoscope body 620 can control the bending of the disposable flexible scope shell 610, so that the reusable urinary flexible scope kit can be applied to the bladder, ureter, kidney and other positions after being matched with different inner cores, and can also be used as a gastroscope, enteroscope and the like. That is, the reusable urinary flexible scope kit in the present application can be a disinfection-free cystoscope kit, a disinfection-free ureteroscope kit, a disinfection-free nephroscope kit, a disinfection-free gastroscope kit, a disinfection-free enteroscope kit, and can be applied to other fields requiring endoscopes.

[0124] Those skilled in the art can understand that the bending section 621 can also adopt a mesh structure, a spiral structure and the like, and the main body section 622 can also adopt other structures, for example, a spring ring or a solid rubber, as long as it has appropriate flexibility.

[0125] The reusable endoscope body 620 further comprises a visual element 624 and at least one illumination element 625. The visual element 624 and the illumination element 625 are installed at the front end of the bending section 621. In the embodiment, two illumination elements 625 are implemented, which are arranged on both sides of the visual element 624.

[0126] The repeatable endoscope body 620 further comprises a light blocking strip 626, which is arranged between the visual element 624 and the illumination element 625 to block the light from the illumination element 625 and prevent the light from affecting the imaging of the visual element 624. Preferably, the light blocking strip 626 is integrally formed with the front end of the curved section 621 and protrudes from the part where the visual element 624 and the illumination element 625 are installed, so as to form a strip-shaped protrusion at the front end of the curved section 621.

[0127] When the repeatable endoscope body 620 moves forward under the action of external force after entering the operation end from the sleeve interface 6103, the front end of the repeatable endoscope body 620 reaches the front end of the sleeve connection channel 6101, the knob 6232 enters the connecting groove 6123, the buckle 6124 and the clamping groove 6234 are connected, and then the repeatable endoscope body 620 is sleeved in the outer shell 610. Since the rear end is connected and fitted, and the front end of the sleeve connection channel 6101 is closed, the repeatable endoscope body 620 will not contact the external environment during application.

[0128] The visual element 624 can be implemented as an electronic mirror or a fiber mirror according to the actual application scene, and the illumination element 625 can be implemented as an LED lamp, an optical fiber or other components capable of providing illumination.

[0129] It is worth mentioning that the front end of the curved section 621 is closed by the closed sleeve connection channel 6101, and the visual element 624 and the illumination element 625 are closed in the sleeve connection channel 6101. Since the front end of the sleeve connection channel 6101 is transparent, the illumination light of the illumination element 625 and the imaging of the visual element 624 will not be affected, so that the corresponding clinical operation can be performed under the visualization condition.

[0130] The disposable soft endoscope shell 610 outside the sleeve connection channel 6101 has certain toughness and elasticity, and can be tightly fitted on the outside of the repeatable endoscope body 620 through external force to prevent air bubbles between the two. After the two are fitted as a whole, they can enter the human body more smoothly and will not cause harm to the human mucosa and other tissues.

[0131] The repeatable endoscope body 620 is preferably of solid structure to ensure its strength, and the solid structure is beneficial to ensure its strength while making it smaller. Compared with the traditional hollow endoscope, the solid repeatable endoscope body 620 in the application is more easily passed through the natural passageway of the human body and is more suitable for being applied to the human body to meet the clinical needs.

[0132] Referring to FIG. 13, a second preferred embodiment of the reusable flexible ureteroscope kit is shown. In this embodiment, the reusable flexible ureteroscope kit comprises a disposable flexible ureteroscope housing 610A and a reusable inner scope 620A which is detachably coupled inside the disposable flexible ureteroscope housing 610A.

[0139] The repeatable endoscope body 620A further comprises a visual element 624A arranged at the front end of the bending section 621A. The front end of the sleeve interface channel 6101A is transparent and closed, and the illumination element 613A is arranged on the shell body 611A at both sides of the sleeve interface channel 6101A. When the repeatable endoscope body 620A is installed in the sleeve interface channel 6101A, the illumination element 613A is located at both sides of the visual element 624A, providing illumination conditions for the imaging of the visual element 624A.

[0140] Since the front end of the sleeve interface channel 6101A is transparent and closed, it will not affect the imaging of the visual element 624A. The visual element 624A is enclosed inside the sleeve interface channel 6101A and will not contact the external environment during application, so it can be directly connected to a new disposable soft scope shell for the next operation without sterilization.

[0141] Since the shell body 611A has an appropriate thickness, the visual element 624A is located inside the shell body 611A, and the illumination element 613A is located outside the shell body 611A. Therefore, when the repeatable endoscope body 620A is sleeved inside the disposable soft scope shell 610A, the illumination element 613A and the visual element 624A are separated by a layer of the shell body 611A, so that the illumination element 613A is located at the front end of the visual element 624A, and the light of the illumination element 613A will not affect the imaging of the visual element 624A, ensuring clear visualization.

[0142] In addition, it is worth mentioning that two said lighting elements 613A can also be said to be between the sleeve channel 6101A and the operation channel 6102A, to provide illumination light to achieve visual operation.

[0143] The shell body 611A is soft, flexible and bendable, and the operation end 612A is relatively hard, so that the reusable endoscope body 620A is more easily sleeved inside the disposable soft scope shell 610A, and handheld operation is facilitated.

[0144] In the embodiment, the bending section 621A and the main body section 622A are implemented as spring ring structures, and the spring ring of the bending section 621A is combed with the spring ring of the main body section 622A, so that the bending section 621A can be better bent, and the strength of the main body section 622A can be ensured. The outer side of the bending section 621A and the main body section 622A are both provided with a smooth inner wall and a smooth outer wall, to ensure the strength of the bending section 621A and the main body section 622A, and facilitate application.
