[0062] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0063] Endoscopes are widely used for in vivo diagnosis and treatment of living organisms. They can explore deep into narrow cavities of curved pipes and observe areas that cannot be directly observed by the human eye.

[0064] In the existing endoscope, during the operation, the photoelectric components are easily in contact with the diseased body components, and it is difficult to ensure that the photoelectric components can be thoroughly disinfected, so that the photoelectric components cannot be reused, resulting in high cost of the endoscope and high cost of the operation.

[0065] The endoscope provided by the embodiment of the present invention is described below by taking a hysteroscope as an example with reference to the accompanying drawings.

[0066] Before hysteroscopic surgery, liquid needs to be injected into the uterus to expand the uterus so as to examine the inside of the uterine cavity and obtain clear images. The surgical instruments can perform surgical operations on the patient's uterine cavity through the hysteroscope. Therefore, it is necessary to implement the injection and discharge operations of liquids such as uterine distention fluid. The uterine distention fluid is introduced into the uterine cavity before the operation, and then discharged after the inspection.

[0067] refer to Figure 1 , Figure 2 and Figure 3 As shown, the present application provides an endoscope, including: a main body 10, a sealing protection member 20 and an optoelectronic assembly 30, including a first shell 11 and a tube body 14, the first shell 11 has a mounting cavity 116, the tube body 14 is connected to the front end of the first shell 11, and the interior of the tube body 14 is connected to the mounting cavity 116;

[0068] The sealing protection member 20 is disposed in the first housing 11 and the tube body 14. The interior of the sealing protection member 20 is connected, and the two connected ends of the sealing protection member 20 are sealed and connected to the installation cavity 116 and the tube body 14 respectively.

[0069] 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 .

[0070] In an endoscope provided by the present invention, a sealing protective member 20 is arranged in the first shell body 11 and the tube body 14, and the two intersecting ends of the sealing protective member 20 are respectively sealed and connected to the installation cavity 116 and the tube body 14, and the imaging unit 40 is penetrated in 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 contacting with the patient's body tissue, ensuring that the photoelectric component 30 is protected from contamination by diseased body tissue. Therefore, the hygienic nature of the secondary reuse of the photoelectric component can be guaranteed, saving the production cost of the endoscope.

[0071] The present invention provides an endoscope, referring to Figure 1 As shown, the first housing 11 may be formed by injection molding, which helps to reduce assembly expenses and lower costs.

[0072] 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.

[0073] In one possible implementation, reference Figure 4 and Figure 5 As shown, the sealing protection member 20 is a circumferentially closed tubular member, so that an imaging channel 21 is formed inside the sealing protection member 20 for the imaging unit 40 to pass through.

[0074] In a possible implementation, the sealing protection member 20 may be a square tube or a round 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.

[0075] The sealing protection member 20 may be a slender pipe, with both ends of the sealing protection member 20 intersecting and being circumferentially closed, thereby preventing distension fluid from entering the imaging channel 21 inside the sealing protection member 20 from the circumference of the sealing protection member 20. The intersecting ends of the sealing protection member 20 are sealedly connected to the mounting cavity 116 and the tube body 14 respectively, which can effectively prevent distension fluid from entering the imaging channel 21 from both ends of the sealing protection member 20, thereby protecting the imaging unit 40 located in the imaging channel 21 from contamination.

[0076] In a 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 .

[0077] The tube body 14 protects the first end of the sealing protection member 20, effectively preventing the distending fluid from entering the sealing protection member 20 from the front end of the tube body 14, thereby protecting the imaging unit 40 located in the imaging channel 21 from being contaminated by the distending fluid or the air in the uterine cavity. The second end of the sealing protection member 20 is sealed and connected to the mounting cavity 116, which can improve the protective effect of the second end of the sealing protection member 20, and prevent germs from entering the imaging channel 21 from the second end of the sealing protection member 20 during surgery, thereby protecting the imaging unit 40 from contamination.

[0078] In a 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 can effectively prevent liquid or air from entering the inside of the sealing protection member 20 from the first end of the sealing protection member 20, and the light-transmitting portion allows light to pass through, so that the imaging unit 40 obtains a clear image.

[0079] In one possible implementation, reference Figure 6 , Figure 7 and Fig. 9As shown, the front end of the tube body 14 has a connecting cap 50, and the connecting cap 50 is sealed and connected to the front end of the tube body 14. Fig.11 and Fig.12 As shown, the connection cap 50 has a light-through hole 55 , and the light-transmitting portion includes a light-transmitting sheet 52 . The light-transmitting sheet 52 covers the light-through hole 55 , and the edge of the light-transmitting sheet 52 is sealed and connected to the light-through hole 55 .

[0080] The connecting cap 50 is sealed and connected to the front end of the tube body 14. For example, a tube sleeve may be provided between the connecting cap 50 and the front end of the tube body 14, and the two ends of the tube sleeve are respectively sleeved on the outer circumferential surface of the connecting cap 50 and the outer circumferential 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 a sealing effect.

[0081] refer to Fig.12 , Fig.13 and Fig.14 As shown, the first end of the sealing protection member 20 is sealedly connected to the front end inner wall surface of the tube body 14, and the first end of the sealing protection member 20 can be sealedly connected to 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 protection member 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 protection member 20, so as to realize the sealed connection between the first end of the sealing protection member 20 and the front end inner wall surface of the tube body 14.

[0082] The light hole 55 is a through hole, and the light-transmitting sheet 52 is covered on the light hole 55 to cover 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 with the light hole 55. For example, a colloid may be provided at the position where the edge of the light-transmitting sheet 52 is connected with the light hole 55, which can not only improve the stability of the installation of the light-transmitting sheet 52, but also achieve a sealing effect.

[0083] The light-transmitting sheet 52 may be a transparent lens, such as a transparent resin sheet or silk-screened glass.

[0084] In one possible implementation, reference Figure 7 and Figure 8 As shown, 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 .

[0085] For example, a colloid may be applied between the outer wall of the second end of the sealing protection member 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 protection member 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 protection member 20 and the inner wall of the mounting cavity 116, and the sealing ring may be squeezed by the outer wall of the second end of the sealing protection member 20 and the inner wall of the mounting cavity 116, so that the sealing ring is deformed, thereby filling the gap between the outer wall of the second end of the sealing protection member 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.

[0086] In a possible implementation, the installation box 31 includes a housing 311 and a connection seat 312. The housing 311 has a sealed cavity 316. The connection seat 312 is disposed in the sealed cavity 316. Figure 4 and Figure 8 As shown, the imaging unit 40 includes a camera 41, and the connection socket 312 is electrically connected to the imaging unit 40 through a signal transmission line 42. The two ends of the signal transmission line 42 are respectively connected to the camera 41 and the connection socket 312. The connection socket 312 is used to electrically connect the signal transmission line 42 and the first housing 11. The signal transmission line 42 is used to realize signal transmission.

[0087] refer to Figure 8 and Fig. 9 As shown, a sheath 421 is provided on the outside of the signal transmission line 42 , and the sheath 421 has a protective effect 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 .

[0088] The outer wall of the cover shell 311 has a first terminal, and the inner wall surface 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 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.

[0089] 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.

[0090] refer to Figure 7 and Figure 8 As shown, the cover 311 can also play a role in protecting the connecting socket 312 .

[0091] In one possible implementation, reference Figure 7 and Figure 8As shown, the side wall of the housing 311 is provided with a mounting hole 313 for the signal transmission line 42 to pass through, and the outer wall of the connection seat 312 is sealed and connected to the mounting hole 313. For example, a colloid may be applied between the outer wall of the connection seat 312 and the inner wall of the mounting hole 313, or a sealing ring may be provided between the outer wall of the connection seat 312 and the inner wall of the mounting hole 313, so as to achieve a sealing effect.

[0092] In a possible implementation, the connection base 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 through hole 3123 is provided in the columnar portion 3121 for the signal transmission line 42 to pass through, the signal transmission line 42 is sealedly connected to the inner wall of the through hole 3123, and 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.

[0093] 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.

[0094] The columnar portion 3121 may be cylindrical, and the mounting hole 313 may be a cylindrical hole.

[0095] The signal transmission line 42 and the inner wall of the via 3123 are sealed and connected. 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 may be filled through the elastic deformation of the waterproof plug, thereby achieving a stable sealing effect.

[0096] In a possible implementation, the installation box 31 further includes an elastic member 315 , which is disposed in the sealing cavity 316 , and abuts against an inner wall of the cover shell 311 facing the installation hole 313 and the connecting seat 312 .

[0097] In a possible implementation, the elastic member 315 may be a spring or an elastic block. Considering the existence of factors such as installation error and production error, there is a problem that there is a gap or excessive extrusion force between the first end of the sealing protection member 20 and the front end inner wall surface of the tube body 14, which affects the use. The present application uses the elastic deformation of the elastic member 315 to keep the first end of the sealing protection member 20 and the front end inner wall surface of the tube body 14 in contact, and can prevent the problem of damage to the light-transmitting sheet 52 caused by excessive thrust of the first end of the sealing protection member 20 on the light-transmitting sheet 52, thereby improving the safety of use and ensuring the use effect.

[0098] In addition, under the action of its own elastic thrust, the elastic member 315 always pushes the connection seat 312 to move toward the mounting hole 313, thereby preventing the connection seat 312 from leaving the mounting hole 313, which is conducive to ensuring the sealing effect of the sealing member 314. It prevents the connection seat 312 inside the mounting box 31 from being contaminated, making the reuse of the optoelectronic component 30 safer and more reliable, while ensuring the hygienic use without causing a substantial increase in production costs.

[0099] 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.

[0100] In one possible implementation, reference Figure 3 and Figure 7 As shown, the first shell 11 is an integrally formed part, and has a first channel 111, a second channel 112, a liquid inlet channel 113 and a liquid outlet channel 114 in the first shell 11.
