Referring to fig. 1 to 4, according to an embodiment of the present application, there is provided an endoscope 10, the endoscope 10 including a scope body 11, a scope tube 12, and a flexible sleeve 13.

Wherein, the lens body 11 is provided with an objective lens 111; the lens tube 12 is disposed at the front end of the lens body 11 and extends in a direction away from the lens body 11, an objective lens channel 121 is disposed in the lens tube 12, an optical lens (not shown in the figure) is disposed in the objective lens channel 121, and the objective lens channel 121 is communicated with a detection channel of the objective lens 111; a flexible sleeve 13 is fitted over the tube 12 at least for damping the tube 12.

Since the endoscope 10 in this embodiment is provided with the flexible sleeve 13, the flexible sleeve 13 is sleeved on the endoscope tube 12, and through the effect of the flexible sleeve 13, when a doctor knocks a surgical instrument around the endoscope 10, the flexible sleeve 13 can play a role in buffering and damping the endoscope tube 12, at this time, the flexible sleeve 13 can play a good role in damping an optical lens in the objective lens channel 121 of the endoscope tube 12, and can play a certain role in protecting the optical lens during operation or use, so that the service life of the endoscope 10 in this embodiment can be prolonged. At the same time, the flexible sleeve 13 also prevents the tube 12 from being scratched or worn, and further improves the service life of the endoscope 10 in this embodiment.

Specifically, the mirror body 11 in the present embodiment has a substantially cylindrical structure, and the mirror tube 12 is disposed at an end of the cylindrical structure during actual processing, and a length direction of the mirror tube 12 is identical to a length direction of the cylindrical structure. The lens tube 12 can be fixedly connected with the lens body 11 in a welding or integral forming mode, and can be detachably connected with the lens body 11 in a screwing, clamping or fastening mode, so long as other deformation modes under the conception of the application are within the protection scope of the application.

Further, the mirror body 11 in this embodiment is further provided with an optical fiber interface 112, a water inlet 113 and a water outlet 114, and correspondingly, the mirror tube 12 is provided with a waterway channel 122 and a light beam channel 124, and the waterway channel 122 and the light beam channel 124 extend along the length direction of the mirror tube 12. The optical fiber interface 112 is used for installing an optical fiber, and is convenient for illuminating the internal environment of a human body through the function of the optical fiber, so that medical staff can observe the focus part of a patient from the objective lens 111 of the endoscope 10, the water inlet 113 and the water outlet 114 are both communicated with the waterway 122, the physiological saline is convenient to convey, and the lens of the endoscope 10, namely the end head of the objective lens channel, can be conveniently cleaned through the function of the waterway 122, and a necessary water environment can be provided for the focus part of the patient. It will be appreciated that in this embodiment, the water inlet 113 and the water outlet 114 may be used interchangeably, and when one is the water inlet, the other is the water outlet. The water inlet 113 and the water outlet 114 are respectively arranged at two sides of the mirror body 11, so that the external pipeline is convenient to be connected to convey normal saline and the like, and of course, in other embodiments of the application, the water inlet 113 and the water outlet 114 can be arranged at intervals along the length direction of the mirror body 11, so long as other deformation modes under the conception of the application are all within the protection scope of the application.

As shown in fig. 2 to 6, the objective lens channel 121 in this embodiment is located at the innermost side of the lens tube 12, the light beam channel 124 is located at the outer periphery of the objective lens channel 121, the waterway channel 122 is located at the outer periphery of the light beam channel 124, and a supporting rib 125 is disposed between the inner wall of the waterway channel 122 and the outer wall of the light beam channel 124, so that the whole lens tube 12 has a compact internal structure, not only can well illuminate, but also can well clean the lens of the endoscope 10, thereby being more convenient for realizing the miniaturized design of the lens tube 12, and the trauma surface of the endoscope 10 to the human body is smaller in the use process. Meanwhile, by disposing the objective passage 121 at the innermost side of the lens tube 12, external knocking or vibration is more difficult to affect the optical lens inside thereof, and the protection of the optical lens is facilitated.

Further, the number of the flexible jackets 13 in the present embodiment may be plural or one, and the case where the number of the flexible jackets 13 is one is shown in the drawings in the present embodiment. When the flexible sleeve 13 is provided as one, the length of the flexible sleeve 13 may be set longer in order to effectively protect the optical lens in the lens tube 12, so that the optical lens can be protected comprehensively. When the flexible sheath 13 is provided in plural, the plural flexible sheaths 13 are provided continuously in order or at intervals in order along the longitudinal direction of the scope 12. That is, the plurality of flexible jackets 13 may be continuously abutted against each other along the length of the tube 12, or may be provided at regular intervals along the length of the tube 12, as long as the tube 12 is capable of absorbing shock. Alternatively, the plurality of flexible sleeves 13 described in the present embodiment may be two, three or more, and are not particularly limited in this application.

Further, the length of the flexible sleeve 13 sleeved on the lens tube 12 in the present embodiment is 1/3 to 1/2, such as 1/3, 3/8 or 1/2, of the length of the lens tube 12. It will be appreciated that when there is one flexible sleeve 13 that is sleeved over the lens tube 12, then the length of the flexible sleeve 13 referred to herein is the length of one flexible sleeve 13 along the length of the lens tube 12; when there are a plurality of flexible sleeves 13 that are sleeved on the lens tube 12, the length of the flexible sleeve 13 referred to herein is the sum of the lengths of all the flexible sleeves 13. When the length of the flexible sleeve 13 is less than 1/3 of the length of the lens tube 12, the flexible sleeve 13 is shorter, so that the optics in the lens tube 12 cannot be well damped, and when the length of the flexible sleeve 13 is greater than 1/2 of the length of the lens tube 12, the flexible sleeve 13 is too long, so that the assembly and the processing production are inconvenient.

In some embodiments of the present application, in order to limit the flexible sleeve 13, a groove 1201 is provided on the outer periphery of the lens tube 12, and the flexible sleeve 13 is embedded and fixed in the groove 1201 during actual installation. In this embodiment, the groove 1201 is formed in the periphery of the flexible sleeve 13 to limit the flexible sleeve 13, so that the flexible sleeve 13 can be well sleeved on the lens tube 12 even if being deformed in long-term use in the actual use process, and the structure is simple, the installation is convenient, and the service life is long.

Of course, in other embodiments of the present application, the flexible sleeve 13 may also be secured to the lens tube 12 by adhesive, snap fit, fastening connection, welding, or the like. In comparison with the above methods, the method of limiting and installing the flexible sleeve 13 by using the groove 1201 is simple in structure and convenient for disinfection and sterilization.

Optionally, the flexible sleeve 13 in this embodiment includes a silicone sleeve or a fluorine rubber sleeve, which has good flexibility and low cost. Of course, in other embodiments of the present application, the flexible sleeve 13 may be made of other composite materials with certain flexibility, and any other structure that can protect the optical lens in the lens tube 12 after being sleeved on the lens tube 12 is within the scope of the present application.

Referring to fig. 1 to 6, in the present application, the lens tube 12 is a relatively slender tube, and in the actual use process, the position where the lens tube 12 is connected to the lens body 11 is easy to bend, and after long-term use, the breakage condition can also occur. For this reason, the endoscope 10 in the present application is further provided with a support portion 14, and the support portion 14 is supported between the scope 11 and the scope 12 for preventing bending of the joint portion of the scope 12 and the scope 11. That is, in the present embodiment, by providing the support portion 14, the position where the scope 12 is most likely to deform can be supported, deformation or bending of the scope 12 can be avoided to some extent, and the service life of the endoscope 10 in the present embodiment can be improved.

Specifically, the support portion 14 in the present embodiment is a support tube, and an end portion of the support tube is connected to the scope 11, and the support tube is sleeved on the scope 12 and extends a predetermined distance in a direction away from the scope 11. Through the effect of this stay tube, can play the effect that supports and intensity strengthen to the position that mirror tube 12 is connected with mirror body 11, so, can avoid mirror tube 12 and mirror body 11 to be connected the position and take place to bend the deformation, and then can improve endoscope 10's life.

Optionally, the support tube in this embodiment is a metal tube, which has high strength and is not easy to deform, so that a good support effect can be achieved on the lens tube 12. Of course, in other embodiments of the present application, the support tube may be provided as a hard tube such as a plastic tube, and any other modification forms under the concept of the present application are within the scope of the present application.

The support tube in this embodiment may be integrally formed with the mirror body 11, or may be separately formed with the mirror body 11 and then assembled into a whole. In the application, the mode of setting the mirror body 11 and the support tube in a split mode is preferably adopted, so that the setting is more convenient for processing the mirror body 11 and the support tube. In actual connection, the support tube and the mirror body 11 may be connected by a clamping connection, a screwing connection, a fastening screw, or the like, so long as other deformation modes under the concept of the present application are all within the scope of the present application.

Alternatively, the length of the support tube in this embodiment is 1/4 to 1/3, such as 1/4, 3/10, or 1/3, of the length of the mirror tube 12. When the length of the support tube is greater than 1/3 of the length of the scope tube 12, the front end operation of the scope tube 12 is inconvenient, a doctor is required to move a long distance to insert the scope tube 12 into a proper operation site or a detection site, and when the length of the support tube is less than 1/4 of the length of the scope tube 12, the effect of preventing the scope tube 12 from being bent is poor. That is, in the present embodiment, by making the length of the support tube 1/4 to 1/3 of the length of the scope tube 12, not only the front end operation of the endoscope 10 is not affected, but also the stability and reliability of the scope tube 12 during use are improved, which is convenient for improving the service life of the endoscope 10 in the present embodiment.

In other embodiments, not shown in the present application, the supporting portion 14 may also be a supporting diagonal rib, which is supported between the outer side surface of the end of the lens tube 12 near the lens body 11 and the lens body 11, so that bending of the end of the lens tube 12 near the lens body 11 relative to the lens body 11 can be avoided, and further the service life of the endoscope 10 in this embodiment can be improved. In other embodiments of the present application, the supporting portion 14 may be a thickened portion integrally formed with the lens tube 12, that is, the thickness of the end of the lens tube 12 near the lens body 11 is set to be relatively thick, so that the strength of the end of the lens tube 12 near the lens body 11 can be increased, and bending deformation of the lens tube 12 is less likely to occur.

According to another aspect of the present application, an endoscopic system is provided, which may be, for example, an endoscopic system for spinal detection or spinal surgical instruments, including the endoscope 10 of the above-described embodiments. Therefore, the endoscope system in this embodiment includes all the technical effects of the endoscope 10 in the above embodiment, and since the technical effects of the endoscope 10 have been described in detail, the description thereof is omitted here.

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In addition, the terms "first", "second", etc. are used to define the components, and are merely for convenience of distinguishing the corresponding components, and unless otherwise stated, the terms have no special meaning, and thus should not be construed as limiting the scope of the present application.

The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and variations may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
