As shown in fig. 1 to 3, the embodiment of the first aspect of the present invention proposes a hard mirror assembly including a hard tube mirror 100, a camera 200 and a protective cover 300. The hard tube lens 100 contains optical elements such as an objective lens, a cylindrical lens, a light guide fiber and the like, one end of the hard tube lens 100 is connected with the camera 200, the other end is a free end, and the free end can extend into a natural cavity of a human body through an entrance such as an oral cavity, a nasal cavity and the like or enter into an abdominal cavity of the human body through an operation incision so as to collect image signals in an operation target cavity such as the abdominal cavity, the nasal cavity and the like, and is transmitted to one end connected with the camera 200 through the optical elements in the hard tube lens 100. The camera 200 can convert the image signal into an electrical signal and transmit the electrical signal through the communication cable 230, and then the electrical signal is converted into an image by the camera host, and the image signal is amplified so as to facilitate the medical staff to observe the situation in the operation target cavity in real time in the operation process.

The camera 200 includes a main body 210 and a knob 220, and the knob 220 is rotatably connected to the main body 210. The knob member 220 has a hollow conduit leading to the body member 210 that can accommodate insertion of the rigid tube scope 100 so that the rigid tube scope 100 can interface with a camera sensor within the body member 210 that converts image signals into electrical signals.

In preparation before operation, the hard tube mirror 100 with proper length and external diameter is selected according to the operation target to be inserted into the knob piece 220, and the knob piece 220 is screwed so as to connect and match the hard tube mirror 100 with the camera 200. After the operation is completed, the knob 220 is unscrewed to facilitate removal of the hard tube scope 100, thereby enabling targeted cleaning and maintenance of the different portions of the hard tube scope assembly. The main body 210 is a main part of the camera 200 for realizing signal conversion, and the main body 210 is provided with a control button 211 so as to adjust imaging parameters of the camera 200, and further, a clearer image effect is presented on the camera host.

In performing an endoscopic procedure, medical personnel typically hold the camera head 200 for manipulation. In order to improve the operation hand feeling of the hard lens to improve the operation precision, the center of gravity of the hard lens is arranged at the camera 200, and when the hard lens is used, stored or in the process, once falling off, the camera 200 can firstly contact the ground to bear the maximum impact force. In order to protect the camera 200, a protective cover 300 is provided in the hard lens assembly of the present invention. The protective sleeve 300 comprises a first protective member 310, a second protective member 320 and at least one connecting member 340, wherein the first protective member 310 is sleeved on the main body member 210, and an avoidance groove 311 is formed on the side surface of the first protective member to expose the control button 211 on the main body member 210, so that the main body member 210 is protected and the adjustment of parameters of the camera 200 is not affected. The second protection member 320 is sleeved on the knob member 220, and is used for protecting the knob member 220. The first and second protectors 310 and 320 are made of silica gel or other flexible materials, and can absorb and release impact force when collision occurs, so that influence of collision on the camera 200 is weakened.

The first protection member 310 and the second protection member 320 are connected through the connection member 340, on one hand, the connection member 340 can apply a pulling force to the second protection member 320 towards the first protection member 310, so that the second protection member 320 can be firmly sleeved on the knob member 220, on the other hand, the connection member 340 can enable the second protection member 320 and the first protection member 310 to be connected into an integral structure, and the first protection member 310 or the second protection member 320 is prevented from being lost after being independently fallen off. For example, as shown in fig. 3, the connection member 340 is formed of an elastic material such that the first protection member 310 is extended straight to the second protection member 320, the second protection member 320 rotates with the rotation of the knob member 220, one end of the connection member 340 connected to the second protection member 320 rotates clockwise or counterclockwise with respect to the other end, and the connection member 340 is elongated and becomes inclined. The number of the connection members 340 is not limited without affecting the relative rotation of the second protection member 320 with respect to the first protection member 310, and may be single or plural, and may be arranged in parallel along the circumferential direction, so as to implement multipoint connection to the second protection member 320.

Based on the above, the hard lens assembly of the present invention protects the camera 200 by providing the first protection member 310 and the second protection member 320, so as to reduce the impact force born by the body of the camera 200 when the camera 200 collides or falls, and reduce the probability of damaging the internal components of the camera 200 or the optical components in the hard tube lens 100.

The rigid tube mirror 100 includes an optical input interface 110, where one end of the optical input interface 110 is connected to a main body of the rigid tube mirror 100, and the other end is used to connect to a light guide 111. As shown in fig. 1, the light input interface 110 extends upward perpendicular to the main body portion of the rigid tube mirror 100. The light input interface 110 is connected with a light guide beam 111 communicated with an external light source (i.e., a light source host in the endoscope apparatus), and an optical fiber is penetrated inside the light guide beam 111. The light guide beam 111 has a certain flexibility and can be bent within an allowable range, but when the light guide beam 111 is excessively bent, the optical fiber is broken, so that the light guide beam 111 is damaged or even scrapped, and because the light input interface 110 is a hard piece and optical elements such as a light cone are arranged in the light input interface, elastic deformation cannot occur, and the phenomenon of stress concentration easily occurs at the joint of the flexible light guide beam 111 and the hard light input interface 110, so that the light guide beam 111 is bent beyond the range. Therefore, as shown in fig. 3, the protection sleeve 300 further includes a third protection member 330, and the third protection member 330 is sleeved on the end of the light guide 111 near the optical input interface 110. The third protector 330 has a rigidity greater than that of the light guide 111, and can bear a larger stress to support the light guide 111; meanwhile, the rigidity of the third protection member 330 is smaller than that of the light input interface 110, so that a certain elastic deformation can occur, and the light input interface 110 and the light guide beam 111 can be flexibly transited. The third protector 330 extends with the light guide 111 in a direction toward the external light source so that a longer range of the light guide 111 is protected.

In order to avoid interference of the light guide 111 with the operation, the light guide 111 and the third protection member 330 are typically bent as shown in fig. 3, so that medical staff can hold the light guide 111 while holding the camera 200 to prevent the light guide 111 from shaking. The camera 200 is connected with a communication cable 230 for transmitting electric signals, and the communication cable 230 is connected with a camera host. The bent light guide 111 is arranged in parallel with the communication cable 230 so as to facilitate the management of the cable by medical staff. In the bent state as shown in fig. 3, for convenience of description, a bent portion of the third protection member 330 is named as a bent section 331, a portion of the third protection member juxtaposed with the communication cable 230 is named as an extension section 332, and an extension direction of the extension section 332 is adjusted along a direction from the light input interface 110 to the light source host through the bent section 331, so that an extension direction of the extension section 3 is the same as an extension direction of the communication cable 2, and further, the light guide beam 111 can be arranged in parallel with the communication cable 230, so that medical staff can manage the wire harness.

In some embodiments, third protector 330 is axially provided with an opening to facilitate peeling third protector 330 from light guide 111. In order to prevent the third protection member 330 from being lost after being removed, the third protection member 330 is further provided with a first connection portion 333 as shown in fig. 3, and the first connection portion 333 may be a common rope fastener or the like for connecting the main body portion of the third protection member 330 and the light guide 111. Correspondingly, the first protection member 310 or the second protection member 320 may also be provided with a rope buckle or other structure for connecting with the camera 200 to avoid losing.

In some embodiments, in order to facilitate bending of the light guide beam 111 to adjust the extending direction of the light guide beam 111, as shown in fig. 3 and 4, a weakening groove 334 extending along the circumferential direction is formed on the outer peripheral surface of the third protection member 330, where the weakening groove 334 may be a through groove capable of exposing the light guide beam 111, or may be a groove imprinted on the outer peripheral surface, so as to weaken the rigidity of the third protection member 330. Since light guide 111 often needs to be bent toward camera 200, light guide 111 gradually approaches camera 200 to facilitate fixation of light guide 111 by medical personnel. Therefore, the weakening groove 334 is disposed on a side of the third protection member 330 near the camera 200, that is, in a bending state, the weakening groove 334 is located on an inner ring side of the bending section 331, when the bending state is performed, the cross-sectional area of the weakening groove 334 is gradually smaller, the groove walls are gradually closer, and the spacing between the groove walls in the bending state should be smaller than the spacing between the groove walls in the straightening state.

The weakening groove 334 reduces the difficulty of bending the light guide beam 111 towards the camera 200, and on the basis, the common bending mode of the light guide beam 111 can be defined by changing the groove width, the groove depth and other dimensions of the weakening groove 334, namely, in the common bending mode, the tangential direction of the light guide beam 111 is gradually adjusted to be the same as the tangential direction of the communication cable 230 and extends in parallel with the communication cable 230, so that medical staff can manage the cable conveniently. Because the setting of weakening groove 334, medical staff can be comparatively easy with the bending of third protection piece 330 to the bending form commonly used, under the bending form commonly used, weaken the mutual butt of cell wall in both sides in groove 334, be difficult to take place the bending of bigger camber to thereby avoid medical staff too big the condition that leads to the excessive bending of third protection piece 330 to lead to the rupture of optic fibre in the light guide 111 with effort.

In other embodiments, the light guide 111 near the light input interface 110 often needs to be bent to change the extending direction of the light guide 111, and the third protection member 330 corresponding to the area needs to be bent. The corresponding tube section of the third protector 330 is easier to bend by changing the tube thickness of the third protector 330. As shown in fig. 5, the third protector 330 has a weakened portion 335 and a guard portion 336, and the thickness of the third protector 330 gradually increases in the direction from the weakened portion 335 to the guard portion 336, so that the bending difficulty gradually increases. When bending, the bending degree of the weakening portion 335 with smaller thickness is larger, the bending degree of the protecting portion 336 with larger thickness is smaller, the two ends of the weakening portion 335 are respectively connected with the protecting portions 336, the curvature of the light guide beam 111 is gradually increased along the extending direction of the light guide beam 111, and the curvature reaches the maximum value at the position with the minimum thickness of the weakening portion 335 and then gradually decreases. In the embodiment shown in fig. 5, the weakening portion 335 is disposed around the third protector 330, and as a modification, in the embodiment shown in fig. 6, the weakening portion 335 may be disposed on a single side of the third protector 330, so that the third protector 330 can be easily bent in a certain setting direction.

The protective sleeve 300 is made of a silica gel material, has good impact resistance and elastic deformation capability, and the chemical property of the silica gel material is relatively stable, and the protective sleeve 300 made of the silica gel material supports disinfection and sterilization treatment along with the camera 200 without being taken down so as to reduce the probability of collision damage of the camera 2 in the disinfection and sterilization process. The first protection member 3 is formed by integral injection molding, and can be fitted on the camera 200. The outer diameter of the camera 200 is not uniform, and in some embodiments, as shown in fig. 2, both ends of the first protection member 3 in the length direction are provided with openings for allowing the knob member 220 and the communication cable 230 to pass therethrough, respectively. When the first protection member 3 is assembled to the camera 200, one of the openings is firstly opened and then is sleeved on the outer circumferential surface of the camera 200, so that the first protection member 3 is required to be capable of being elastically deformed to a certain extent, and the inner diameter of the first protection member 3 can be larger than the outer diameter of the maximum end of the camera 200 when being opened so as to allow the camera 200 to be inserted into the inner cavity of the camera.

In other embodiments, the side of the first protection member 310 further has a mounting opening (not shown) that may extend along the length of the camera head 200 so that the body member 210 of the camera head 200 can be removed from the side of the first protection member 310. The mounting opening may also be disposed along the circumferential direction of the camera 200, where the largest outer diameter of the camera 200 is provided with an annular mounting opening, the first protection member 310 is divided into two sub first protection members, the two sub first protection members may be independent of each other or may be partially connected, and the two sub first protection members are spliced to form the complete first protection member 310. The first protection member 310 further has a second connection portion for closing the mounting opening, where the second connection portion may be a common buckle, disposed on either side of the mounting opening along the width direction and extending toward the other side, and a slot adapted to the buckle is disposed on the surface of the other side of the mounting opening, and after the main body member 210 is mounted through the mounting opening, the buckle cooperates with the slot to close the mounting opening, so as to prevent the main body member 210 of the camera 200 from falling out of the first protection member 310.
