DETAILED DESCRIPTION

[0057] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0058] Endoscopes are widely used for in vivo diagnosis and treatment of living organisms. They can explore deep into narrow cavities in curved pipes and observe areas that cannot be directly observed by the human eye.

[0059] In existing endoscopes, the photoelectric components are easily in contact with diseased body parts during surgery, making it difficult to ensure that the photoelectric components can be thoroughly disinfected, making the photoelectric components non-reusable, resulting in high endoscope costs and high surgical fees.

[0060] The endoscope provided in the embodiment of the present application will be described below with reference to the accompanying drawings, taking a hysteroscope as an example.

[0061] Before a hysteroscopic procedure, fluid is injected into the uterus to expand it and allow for examination of the interior of the uterine cavity and to obtain clear images. Surgical instruments, through the hysteroscope, can perform surgical operations on the patient's uterine cavity. Therefore, it is necessary to implement the injection and removal of fluids, such as distention fluid, which is introduced into the uterine cavity before the procedure and then removed after the examination.

[0062] 1 , 2 , and 3 , the present application provides an endoscope, comprising: a main body 10 , a sealing protective member 20 , and an optoelectronic assembly 30 , including a first housing 11 and a tube 14 , wherein the first housing 11 has a mounting cavity 116 , the tube 14 is connected to the front end of the first housing 11 , and the interior of the tube 14 is in communication with the mounting cavity 116 ;

[0063] The sealing protection member 20 is disposed within the first housing 11 and the tube body 14. The interior of the sealing protection member 20 is interconnected, and the two interconnected ends of the sealing protection member 20 are sealedly connected to the mounting cavity 116 and the tube body 14, respectively.

[0064] The optoelectronic assembly 30 includes a mounting box 31 and an imaging unit 40 connected to the mounting box 31 . The imaging unit 40 is disposed in the sealing protection member 20 , and the mounting box 31 is disposed in the mounting cavity 116 .

[0065] The present application provides an endoscope, in which the sealing protective member 20 is arranged in the first shell 11 and the tube body 14, the two ends of the sealing protective member 20 are sealed and connected to the installation cavity 116 and the tube body 14 respectively, and the imaging unit 40 is passed through the sealing protective member 20, and the installation box 31 is arranged in the installation cavity 116, thereby achieving effective isolation of the photoelectric component 30, so that during the operation, the photoelectric component 30 is prevented from coming into contact with the patient's body tissue, and the photoelectric component 30 is protected from contamination by diseased body tissue. Therefore, the hygiene of the secondary reuse of the photoelectric component can be guaranteed, saving the production cost of the endoscope.

[0066] In an endoscope provided by the present application, as shown in FIG1 , the first shell 11 may be formed by injection molding, which helps to reduce assembly costs and lower costs.

[0067] When in use, the front end of the tube body 14 is inserted into the human body or animal body to inspect and treat the diseased part.

[0068] In a possible implementation, referring to FIG. 4 and FIG. 5 , the sealing protection member 20 is a circumferentially closed tubular member, so as to form an imaging channel 21 in the sealing protection member 20 for the imaging unit 40 to pass through.

[0069] In a possible implementation, the sealing protection member 20 may be a square tube or a circular tube, through which the imaging unit 40 can pass. The sealing protection member 20 is used to protect the imaging unit 40 so that the imaging unit 40 is in a relatively sealed environment.

[0070] The sealing protector 20 can be an elongated tube, with its two ends intersecting and circumferentially closed, thereby preventing distension fluid from entering the imaging channel 21 within the sealing protector 20 from the circumference of the sealing protector 20. Since the two intersecting ends of the sealing protector 20 are sealedly connected to the mounting cavity 116 and the tube body 14, respectively, distension fluid can be effectively prevented from entering the imaging channel 21 from the two ends of the sealing protector 20, thereby protecting the imaging unit 40 located within the imaging channel 21 from contamination.

[0071] In one possible implementation, the first end of the sealing protection member 20 is inserted into the tube body 14 and is sealed to the front inner wall surface of the tube body 14 ; the second end of the sealing protection member 20 is sealed to the installation cavity 116 .

[0072] Tube 14 protects the first end of sealing member 20, effectively preventing distending fluid from entering sealing member 20 through the front end of tube 14. This protects imaging unit 40 within imaging channel 21 from contamination by distending fluid or air within the uterine cavity. The second end of sealing member 20 is sealedly connected to mounting cavity 116, further enhancing the protective effect of sealing member 20. During surgery, pathogens are prevented from entering imaging channel 21 through the second end of sealing member 20, thereby protecting imaging unit 40 from contamination.

[0073] In one possible implementation, the front end of the tube body 14 has a closed light-transmitting portion, and the first end of the sealing protection member 20 abuts against the inner wall surface of the front end of the tube body 14. The closed light-transmitting portion effectively prevents liquid or air from entering the interior of the sealing protection member 20 through the first end of the sealing protection member 20. The light-transmitting portion allows light to pass through, allowing the imaging unit 40 to capture clear images.

[0074] In one possible implementation, referring to Figures 6, 7 and 9, the front end of the tube body 14 has a connecting cap 50, which is sealed to the front end of the tube body 14. Referring to Figures 11 and 12, the connecting cap 50 has a light-through hole 55, and the light-transmitting portion includes a light-transmitting sheet 52, which covers the light-through hole 55, and the edge of the light-transmitting sheet 52 is sealed to the light-through hole 55.

[0075] The connecting cap 50 is sealedly connected to the front end of the tube body 14. For example, a tube sleeve can be provided between the connecting cap 50 and the front end of the tube body 14. The two ends of the tube sleeve are respectively sleeved on the outer peripheral surface of the connecting cap 50 and the outer peripheral surface of the front end of the tube body 14, and a colloid is applied between the tube sleeve and the connecting cap 50, and between the tube sleeve and the front end of the tube body 14 to ensure the sealing effect.

[0076] Referring to Figures 12, 13 and 14, the first end of the sealing protector 20 is sealedly connected to the inner wall surface of the front end of the tube body 14. It can be a sealed connection between the first end of the sealing protector 20 and the inner wall surface of the connecting cap 50. For example, a colloid is applied between the outer wall surface of the first end of the sealing protector 20 and the inner wall surface of the connecting cap 50, or a sealing ring is provided on the outer wall surface of the first end of the sealing protector 20 to achieve a sealed connection between the first end of the sealing protector 20 and the inner wall surface of the front end of the tube body 14.

[0077] The light hole 55 is a through hole, and the light-transmitting sheet 52 is disposed over the light hole 55 to block the light hole 55 and prevent liquid or air from passing through the light hole 55. The edge of the light-transmitting sheet 52 is sealed to the light hole 55. For example, a colloid may be disposed at the location where the edge of the light-transmitting sheet 52 connects to the light hole 55. This can not only improve the stability of the installation of the light-transmitting sheet 52, but also provide a sealing effect.

[0078] The light-transmitting sheet 52 may be a transparent lens, such as a transparent resin sheet or silk-screened glass.

[0079] In a possible implementation, referring to FIG. 7 and FIG. 8 , the second end of the sealing protection member 20 extends into the mounting cavity 116 and is sealedly connected to the inner wall of the mounting cavity 116 .

[0080] For example, a colloid may be applied between the outer wall of the second end of the sealing protector 20 and the inner wall of the mounting cavity 116, thereby filling the gap between the outer wall of the second end of the sealing protector 20 and the inner wall of the mounting cavity 116, preventing liquid from passing through, and achieving a sealed connection. Alternatively, a sealing ring may be provided between the outer wall of the second end of the sealing protector 20 and the inner wall of the mounting cavity 116, and the sealing ring may be squeezed between the outer wall of the second end of the sealing protector 20 and the inner wall of the mounting cavity 116, causing the sealing ring to deform, thereby filling the gap between the outer wall of the second end of the sealing protector 20 and the inner wall of the mounting cavity 116, and achieving a sealing effect. The sealing ring includes, but is not limited to, materials such as rubber and silicone.

[0081] In one possible implementation, the mounting box 31 includes a housing 311 and a connector 312. The housing 311 has a sealed cavity 316 therein, and the connector 312 is disposed within the sealed cavity 316. Referring to Figures 4 and 8 , the imaging unit 40 includes a camera 41 and a signal transmission line 42. The ends of the signal transmission line 42 are respectively connected to the camera 41 and the connector 312. The connector 312 is used to electrically connect the signal transmission line 42 to the first housing 11. The signal transmission line 42 is used to transmit signals.

[0082] 8 and 9 , a sheath 421 is provided on the outside of the signal transmission line 42 . The sheath 421 provides protection and improves the rigidity of the signal transmission line 42 , so that the signal transmission line 42 remains stretched and straight in the imaging channel 21 .

[0083] The outer wall of the cover 311 has a first terminal, and the inner wall of the installation cavity 116 has a second terminal. When the installation box 31 is installed in the installation cavity 116, the positions of the first terminal and the second terminal correspond to each other and are electrically connected. The first terminal and the second terminal can be electrically connected by plugging to ensure the stability of the electrical connection.

[0084] The connection base 312 has a third terminal, which is electrically connected to the first terminal. The signal transmission line 42 is electrically connected to the third terminal of the connection base 312, thereby realizing electrical connection between the signal transmission line 42 and the second terminal.

[0085] 7 and 8 , the cover 311 can also protect the connection base 312 .

[0086] In one possible implementation, as shown in Figures 7 and 8 , a mounting hole 313 is defined in the side wall of the housing 311 for passage of the signal transmission line 42, and the outer wall of the connector 312 is sealed to the mounting hole 313. For example, a colloid may be applied between the outer wall of the connector 312 and the inner wall of the mounting hole 313, or a sealing ring may be provided between the outer wall of the connector 312 and the inner wall of the mounting hole 313 to achieve a sealing effect.

[0087] In one possible implementation, the connector 312 includes a columnar portion 3121 and a plate portion 3122 connected to one end of the columnar portion 3121. The columnar portion 3121 extends into the mounting hole 313. A via 3123 is defined within the columnar portion 3121 for the signal transmission line 42 to pass through. The signal transmission line 42 is sealed to the inner wall of the via 3123. A seal 314 is provided between the columnar portion 3121 and the inner wall of the mounting hole 313. The third terminal may be fixed to the plate portion 3122.

[0088] The sealing member 314 may be a rubber ring. The sealing member 314 is elastically deformed when squeezed, and can fill the gap between the columnar portion 3121 and the inner wall of the mounting hole 313 to achieve a sealing effect.

[0089] The columnar portion 3121 may be cylindrical, and the mounting hole 313 may be a cylindrical hole.

[0090] The signal transmission line 42 and the inner wall of the via 3123 are sealed. For example, a colloid may be provided between the signal transmission line 42 and the inner wall of the via 3123, and the colloid may fill the gap between the signal transmission line 42 and the inner wall of the via 3123 to achieve a sealing effect. Alternatively, a waterproof plug may be provided on the outer wall of the signal transmission line 42, and the waterproof plug may be inserted into the via 3123, so that the gap between the signal transmission line 42 and the inner wall of the via 3123 is filled through the elastic deformation of the waterproof plug, thereby achieving a stable sealing effect.

[0091] In a possible implementation, the mounting box 31 further includes an elastic member 315 . The elastic member 315 is disposed in the sealed cavity 316 , and the elastic member 315 abuts between the inner wall of the cover 311 facing the mounting hole 313 and the connecting seat 312 .

[0092] In one possible implementation, the elastic member 315 may be a spring or an elastic block. Considering factors such as installation and production errors, a gap or excessive extrusion force may easily exist between the first end of the sealing member 20 and the front inner wall of the tube body 14, thereby affecting use. The present application utilizes the elastic deformation of the elastic member 315 to maintain contact between the first end of the sealing member 20 and the front inner wall of the tube body 14. This prevents damage to the light-transmitting sheet 52 caused by excessive thrust from the first end of the sealing member 20, thereby improving safety and ensuring effective use.

[0093] In addition, under the action of its own elastic thrust, the elastic member 315 always pushes the connecting seat 312 to move towards the mounting hole 313, thereby preventing the connecting seat 312 from leaving the mounting hole 313, which is conducive to ensuring the sealing effect of the sealing member 314.

[0094] In order to improve the stability of the fixation of the elastic member 315, a first boss is provided on the inner wall of the cover shell 311 facing the mounting hole 313, and a second boss is provided on the side of the plate portion 3122 facing away from the columnar portion 3121. The two ends of the elastic member 315 are respectively mounted on the first boss and the second boss, which can effectively prevent the elastic member 315 from falling off and improve the stability of the installation of the elastic member 315.

[0095] In one possible implementation, referring to Figures 3 and 7, the first shell 11 is an integrally molded part, and the first shell 11 has a first channel 111, a second channel 112, a liquid inlet channel 113 and a liquid outlet channel 114. The first channel 111 and the second channel 112 are both connected to the interior of the tube body 14, and at least part of the structure of the sealing protection component 20 is arranged in the first channel 111; the liquid inlet channel 113 is connected to the first channel 111, and the liquid outlet channel 114 is connected to the second channel 112.

[0096] In one possible implementation, referring to Figures 3 and 7, the extension directions of the first channel 111 and the second channel 112 are parallel to each other, the liquid inlet channel 113 can be located on the side wall of the first channel 111, and the liquid outlet channel 114 can be located on the side wall of the second channel 112. The first channel 111 and the second channel 112 are separated inside the first shell 11, so that the first channel 111 and the second channel 112 remain relatively independent.

[0097] In a possible implementation, the front end of the first shell 11 has a communication port, the tube 14 is sealed and connected to the communication port, and the first channel 111 and the second channel 112 are both connected to the communication port.

[0098] In order to prevent leakage at the connection position between the front end of the first shell 11 and the tube body 14, a colloid is applied between the communication port and the tube body 14, which can not only improve the stability of the connection, but also have a sealing effect to prevent leakage.

[0099] In a possible implementation, the liquid inlet channel 113 is connected to a side of the first channel 111 , and the liquid outlet channel 114 is connected to a side of the second channel 112 .

[0100] In a possible implementation, the liquid inlet channel 113 may be connected to a liquid inlet valve, and the liquid outlet channel 114 may be connected to a liquid outlet valve.

[0101] 7 and 9 , the tube body 14 includes an inner pipe 141 , one end of the inner pipe 141 is sealedly connected to the inner wall surface of the front end of the tube body 14 , and is communicated with the outside of the tube body 14 from the front end of the tube body 14 , and the other end of the inner pipe 141 extends into the second channel 112 and is communicated with the liquid outlet channel 114 .

[0102] The inner pipe 141 and the inner wall surface of the front end of the tube body 14 can be connected by a colloid, which not only improves the stability of the fixation of the inner pipe 141, but also forms a sealing effect between the front end of the tube body 14 and the inner pipe 141.

[0103] A flow channel 118 is formed between the inner pipe 141 and the inner wall of the tube body 14 . The flow channel 118 is in communication with the liquid inlet channel 113 , and the liquid outlet channel 114 is in communication with the second channel 112 .

[0104] Surgical instruments can be operated through the second channel 112 and the inner tube 141. Liquid can enter the uterine cavity through the liquid inlet channel 113 and the flow channel 118. When the liquid is discharged, it enters the liquid outlet channel 114 through the inner tube 141 for discharge, thus realizing a dual channel for the instrument's working cycle and water circulation. The simple structure does not require complex assembly operations, which helps reduce the production cost of the endoscope.

[0105] 2 , 11 , and 12 , a liquid return port 53 and a liquid outlet 54 are provided in the connection cap 50. The liquid return port 53 communicates with the interior of the inner conduit 141, and the liquid outlet 54 communicates with the overflow channel 118.

The end of the first channel 111 away from the tubular body 14 is sealed to the outer wall of the second section. For example, a colloid may be applied between the end of the first channel 111 away from the tubular body 14 and the outer wall of the second section to achieve a sealed connection, thereby preventing leakage of uterine distension fluid from the end of the first channel 111 away from the tubular body 14.

[0111] In a possible implementation, the sealing protection member 20 may be an integrally formed structure.

[0112] In one possible implementation, a fixing seat 115 is formed at one end of the first shell 11 away from the tube body 14, the installation cavity 116 is located in the fixing seat 115, and the fixing seat 115 has a disassembly port at one end relative to the sealing protective member 20. The main body 10 also includes an end cover 13, which covers the disassembly port.

[0113] In a possible implementation, the fixing seat 115 and the first shell 11 are an integrally formed structure, which does not require assembly work and is conducive to saving assembly costs.

[0114] The installation box 31 can be plugged into the installation cavity 116 , which is convenient for installation and disassembly of the optoelectronic component 30 .

[0115] In one possible implementation, referring to FIG. 4 , FIG. 8 and FIG. 10 , the end cover 13 is hinged to the outer wall surface of the fixing seat 115 , and a sealing ring 133 is provided between the end cover 13 and the outer peripheral surface of the fixing seat 115 .

[0116] The end cover 13 serves to protect the optoelectronic component 30. When the end cover 13 is flipped upward to open the installation cavity 116, the installation box 31 of the optoelectronic component 30 is exposed, making it easy to disassemble the optoelectronic component 30. Referring to Figure 2, when the end cover 13 is flipped downward to close the installation cavity 116, the optoelectronic component 30 can be sealed in the installation cavity 116.

[0117] In the present application, a sealing ring 133 is provided between the end cover 13 and the outer circumferential surface of the fixing seat 115 , thereby improving the sealing performance between the end cover 13 and the fixing seat 115 .

[0118] In one possible implementation, referring to Figures 4, 8 and 10, the end cover 13 and the fixing seat 115 can be connected by a pin. For example, the outer wall of the fixing seat 115 has a first protrusion 117, and the outer side surface of the end cover 13 has a second protrusion 131. The pin is passed through the first protrusion 117 and the second protrusion 131, so that the end cover 13 can flip relative to the fixing seat 115.

[0119] In a possible implementation, the end cover 13 and the fixing seat 115 are connected via a tough portion, and the end cover 13, the fixing seat 115 and the tough portion are an integrally formed structure.

[0120] The tough portion may be, for example, a thin sheet-shaped component with a certain degree of flexibility. The tough portion may be made of, for example, polypropylene (PP), which can be bent repeatedly and is durable.

[0121] In one possible implementation, referring to Figures 8 and 10, the end of the second channel 112 away from the tube body 14 extends into the fixed seat 115, and the main body 10 also includes a waterproof sleeve 60, which abuts between the end of the first channel 111 away from the tube body 14 and the end cover 13.

[0122] The waterproof baffle 60 includes a sleeve portion 61 and a seal 62 that are interconnected. The sleeve portion 61 is mounted on the outer wall of the second channel 112, and the seal 62 is positioned against the end of the first channel 111 away from the tube body 14. Since liquid entering the inner pipe 141 from the liquid return port 53 will enter the second channel 112, the waterproof baffle 60 serves to seal the second channel 112.

[0123] The sleeve portion 61 is arranged on the outer wall surface of the second channel 112. The inner wall of the sleeve portion 61 and the outer wall surface of the second channel 112 can be connected by screw thread or by interference fit.

[0124] In one possible implementation, the stopper 62 is a flexible member with a slit defined therein. The slit allows surgical instruments, such as a scalpel, to pass through the slit and into the second passage 112. The edges of the slit abut against the surgical instruments, ensuring the sealing of the second passage 112.

[0125] In a possible implementation, the slit may be in a straight line shape, for example.

[0126] In a possible implementation, the stop seal 62 may be made of, for example, rubber or silicone material, and may have a certain degree of elasticity. The stop seal 62 may be an integral structure integrally formed with the sleeve portion 61 .

[0127] In one possible implementation, the waterproof baffle sleeve 60 can also be fixed to the side of the end cover 13 facing the second channel 112. When the end cover 13 is closed, the end cover 13 squeezes the waterproof baffle sleeve 60, thereby increasing the clamping force between the waterproof baffle sleeve 60 and the end of the second channel 112 and improving the sealing performance.

[0128] In one possible implementation, referring to Figures 1 and 2, the main body 10 also includes a second shell 12, the second shell 12 includes a protective portion 121, and the protective portion 121 has a protective cavity 123. At least part of the first shell 11 is arranged in the protective cavity 123, and the liquid inlet channel 113 and the liquid outlet channel 114 both extend through the inner wall of the second shell 12 to the outside of the second shell 12.

[0129] The second shell 12 can protect the first shell 11 .

[0130] In one possible implementation, referring to Figures 5 and 6, the second shell 12 also includes a handle portion 122, which is interconnected with the protective portion 121. For example, the handle portion 122 is connected to one side of the protective portion 121, so that the second shell 12 is roughly pistol-shaped.

[0131] In one possible implementation, the handle portion 122 and the protective portion 121 may be an integrally formed structure.

[0132] In one possible implementation, as shown in Figures 1 and 2 , the endoscope further includes a control board 80. The control board 80 may be disposed within the handle portion 122. The control board 80 is electrically connected to a second terminal located on the inner wall of the mounting cavity 116 via a wire. The control board 80 is used to control the operation of the optoelectronic assembly 30. The control board 80 may be, for example, a circuit board. As shown in Figures 6 and 7 , the endoscope further includes a control switch 81. The control switch 81 may be disposed within the handle portion 122 and electrically connected to the control board 80.

[0133] In one possible implementation, as shown in Figures 16, 17, and 18, an operating hole 132 is provided in the end cap 13, through which the stop seal 62 is exposed. When the end cap 13 is closed, surgical instruments such as a scalpel can be inserted into the second passage 112 through the slit in the stop seal 62 for convenient operation.

[0134] An endoscope provided in the present application takes into account the high cost of the photoelectric component 30. By making the photoelectric component 30 detachable, it is prevented from coming into contact with the patient's body tissue and uterine distension fluid, ensuring that the photoelectric component 30 will not be contaminated, allowing the photoelectric component 30 to be disassembled for secondary use, solving the problem of cross infection, meeting medical standards, helping to reduce production costs and ensuring safety and hygiene.

[0135] The present application provides an endoscope in which the tube body 14 is connected to the front end of the first shell 11. The liquid entering through the liquid inlet channel 113 can smoothly enter the flow channel 118 from the front end of the first channel 111, and then flow along the flow channel 118 and enter the uterine cavity from the liquid outlet 54; when the liquid is discharged, the liquid enters the interior of the inner pipe 141 from the return liquid port 53, and then is discharged from the liquid outlet channel 114, thereby realizing the flow of the liquid.

[0136] The present application provides an endoscope, in which the inner tube 141 is used for both passing surgical instruments for surgical operations and passing recovered liquids, so that the inner diameter of the inner tube 141 is larger, which not only facilitates the operation of surgical instruments but also increases the recovery speed of the liquid.
