Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and more specifically, to an endoscope body mounting device. In addition, the utility model also relates to an endoscope system comprising the endoscope body mounting device. Background Art

[0002] Endoscopic systems are widely used in clinical surgery. For example, laparoscope, as a type of endoscope, is used in minimally invasive abdominal surgery. It enters the human body through a surgical incision in a sterile environment to diagnose the internal conditions of the human body and complete inspection, diagnosis and treatment.

[0003] The endoscope system in the prior art includes an endoscope and an optical bayonet, wherein the endoscope is inserted into the optical bayonet, and the optical bayonet clamps the endoscope with claws by means of spring elastic force. During installation, a manual external force is applied to the handle on the optical bayonet so that the handle drives the claws to open, and the claws are kept open by continuously grasping the handle with force, and then the eyepiece cover of the endoscope is installed into the optical bayonet, and then the handle is released so that the handle drives the claws to tighten and reset under the action of the spring elastic force to clamp the endoscope.

[0004] That is to say, when assembling the endoscope and the optical mount, the operator needs to keep applying force to the handle with one hand to overcome the spring force, and use the other hand to install the endoscope. This makes the installation inconvenient and requires high coordination from the operator. Moreover, in order for the claw to have sufficient clamping force on the endoscope, the spring force is relatively large. Therefore, the operator's driving force on the handle is relatively large. Applying force with one hand for a long time can easily lead to fatigue, and there is a risk that the endoscope cannot be installed or may fall off.

[0005] Therefore, how to prevent the operator from continuously applying force when installing the endoscope is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, an object of the present invention is to provide an endoscope body mounting device, which can avoid the operator from continuously applying force when installing the endoscope.

[0007] Another object of the utility model is to provide an endoscope system including the endoscope body mounting device, which is convenient for the installation of the endoscope.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] An endoscope body mounting device has a mounting channel for inserting and mounting the endoscope body, comprising:

[0010] A fixing member disposed on the outer periphery of the installation channel;

[0013] a first elastic member, which provides a force to drive the movable member to rotate in the opposite direction or provides a force to extend the claw into the installation channel when the movable member is rotated by an external force;

[0014] The locking piece is fixedly arranged on the fixing piece and has a telescopic function. When the movable piece rotates to a set position relative to the fixing piece, the pin hole is aligned with one end of the locking piece, and the locking piece extends into the pin hole, so that the movable piece stops rotating relative to the fixing piece and the claw is limited to a retracted position allowing the endoscope body to be installed and disassembled; when the locking piece retracts from the pin hole, the movable piece and the claw are unlocked.

[0015] Optionally, the pin hole is a through hole, and one end of the locking piece extends into the pin hole and then extends out into the installation channel, so that when the endoscope body is inserted into the installation channel, it is pushed by the endoscope body and retracted from the pin hole.

[0016] Optionally, the locking element comprises:

[0017] A telescopic column, used to extend into the pin hole or retract from the pin hole;

[0018] The second elastic member is disposed between the telescopic column and the fixing member, and applies an elastic force to the telescopic column to extend into the pin hole.

[0019] Optionally, a universal ball is embedded in one end of the telescopic column facing the pin hole;

[0020] Alternatively, the telescopic column has an end facing the pin hole provided with a spherical surface, an inclined surface or an arcuate surface.

[0021] Optionally, the locking member is provided with a guide limiting hole, and the telescopic column and the second elastic member are arranged in the guide limiting hole.

[0022] Optionally, the guide limiting hole is a stepped hole, and a limiting portion is provided at one end of the telescopic column facing the second elastic member, and the limiting portion is used to cooperate with a step surface of the stepped hole for limiting.

[0023] Optionally, the pin hole is arranged on a side wall of the movable part in a circumferential direction around the installation channel; or,

[0024] The pin hole is arranged on the bottom wall of the movable part facing the insertion end of the endoscope body.

[0025] Optionally, the movable member is provided with a slide groove, the locking member is embedded in the slide groove, and the two can slide relative to each other.

[0026] Optionally, the first elastic member is embedded in the slide groove, and one end of the first elastic member is fixedly connected to the locking member, and the other end of the first elastic member is fixedly connected to the movable member.

[0027] Optionally, the first elastic member is a spring, the movable member is provided with a column, and the column is stuck in the gap at one end of the spring.

[0028] Optionally, the locking member is provided with a reset button, and when the reset button is pressed, one end of the locking member retracts from the pin hole.

[0029] Optionally, an operating handle is provided on an outer wall of the fixed part and / or the movable part.

[0030] Optionally, the fixing member is provided with a strip groove along the circumferential direction, the movable member is embedded in the fixing member, and the operating handle of the movable member passes through the strip groove.

[0031] An endoscope system comprises an endoscope and any one of the above-mentioned endoscope body mounting devices.

[0032] The utility model provides an endoscope body installation device. When installing the endoscope body, an external force is used to rotate the movable part relative to the fixed part. At this time, the claw is driven by the movable part to move between the movable part and the fixed part, and then retracts from the installation channel. In the process of retracting the claw from the installation channel, the pin hole is not aligned with the locking part; when the movable part rotates to a set position relative to the fixed part, the pin hole is aligned with one end of the locking part. At this time, the locking part extends into the pin hole, and the limiting effect of the pin hole on the locking part is utilized to achieve relative fixation of the fixed part and the movable part, so that the movable part stops rotating relative to the fixed part. At this time, the movable part cannot drive the claw to move, so that the claw is limited to the retracted position allowing the endoscope body to be installed and disassembled, and remains in an open state; in this case, the endoscope body is inserted into the installation channel again. When the endoscope body is inserted into the installation channel and is in place, the locking piece is retracted from the pin hole, and the locking piece can release the lock on the movable piece and the claw. At this time, under the action of the elastic force of the first elastic piece, the movable piece is rotated in the opposite direction relative to the fixed piece, and the claw is then driven by the movable piece to extend into the installation channel; or, the elastic force of the first elastic piece directly acts on the claw, causing the claw to extend into the installation channel to fix the endoscope body.

[0033] The locking member and the pin hole are used to limit the position of the movable member, and the self-locking of the movable member and the fixed member is achieved, so that the claws are continuously kept in the open state, thereby avoiding the situation in the prior art that the user continuously applies force to open the claws. This is equivalent to dividing the process of simultaneously applying force to open the claws and installing the endoscope in the prior art into two different stages, that is, first, force is applied to the movable member to open the claws, and the locking member and the pin hole are used to limit the position of the claws to maintain the open state, and then the endoscope body is installed. The action of installing the endoscope body is completed separately from the action of applying force to the movable member. The open state of the claws is maintained by the self-locking achieved by the locking member and the pin hole. On the one hand, manpower is saved, and on the other hand, fatigue of the user caused by continuous force to open the claws can be avoided. At the same time, the coordination requirement for the user to simultaneously apply force to keep the claws open and install the endoscope is avoided, thereby ensuring the reliability of the installation of the endoscope body, preventing the endoscope body from being unable to be installed or falling off, and protecting the equipment and property safety.

[0034] The endoscope system provided by the utility model comprises the endoscope body mounting device and has the above-mentioned beneficial effects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] The core of the utility model is to provide an endoscope body installation device, which can avoid the operator from applying continuous force when installing the endoscope. Another core of the utility model is to provide an endoscope system including the endoscope body installation device, which is convenient for endoscope installation.

[0050] Please combine Figure 1-Figure 4The embodiment of the utility model provides an endoscope body installation device, which has an installation channel 21 for inserting and installing the endoscope body, and the endoscope body installation device includes a fixed part 1, a movable part 2, a claw 3, a first elastic part 5 and a locking part 4. The fixed part 1 is arranged on the outer periphery of the installation channel 21; the movable part 2 is rotatably connected with the fixed part 1, and the movable part 2 can rotate around the installation channel 21, and a pin hole 22 is provided on the movable part 2; the claw 3 is movably installed between the fixed part 1 and the movable part 2, and when the movable part 2 rotates relative to the fixed part 1, the claw 3 extends into the installation channel 21 or retracts from the installation channel 21 to fix. The movable part 2 is fixed or released to the endoscope body; when the movable part 2 is rotated by an external force, the first elastic member 5 provides the movable part 2 with a force to drive it to rotate in the opposite direction or provides the claw 3 with a force to extend into the installation channel 21; the locking member 4 is arranged on the fixed part 1 and has a telescopic function. When the movable part 2 rotates to a set position relative to the fixed part 1, the pin hole 22 is aligned with one end of the locking member 4, and the locking member 4 extends into the pin hole 22, so that the movable part 2 stops rotating relative to the fixed part 1 and the claw 3 is limited to a retracted position allowing the installation and removal of the endoscope body; when the locking member 4 retracts from the pin hole 22, the locking of the movable part 2 and the claw 3 is released.

[0051] It should be noted that when the claw 3 is extended into the installation channel 21, it can clamp the endoscope body and fix the endoscope body; when the claw 3 is retracted from the installation channel 21, that is, the claw 3 is opened, the endoscope body is released, and the endoscope body can be removed from the installation channel 21 at this time; at the same time, the opening of the claw 3 also facilitates the installation of the endoscope body.

[0052] When installing the endoscope body, the movable part 2 is rotated relative to the fixed part 1 by external force. At this time, the claw 3 is driven by the movable part 2 to move between the movable part 2 and the fixed part 1, and then retracts from the installation channel 21. In the process of retracting the claw 3 from the installation channel 21, the pin hole 22 is not aligned with the locking part 4; when the movable part 2 is rotated to the set position relative to the fixed part 1, the pin hole 22 is aligned with one end of the locking part 4. At this time, the locking part 4 extends into the pin hole 22, and the limiting effect of the pin hole 22 on the locking part 4 is utilized to achieve relative fixation of the fixed part 1 and the movable part 2, so that the movable part 2 stops rotating relative to the fixed part 1. At this time, the movable part 2 cannot drive the claw 3 to move, so that the claw 3 is limited to the retracted position allowing the installation and disassembly of the endoscope body, and remains in an open state; in this case, the endoscope body is inserted into the installation channel 21 again. When the endoscope body is inserted into the installation channel 21 and is in place, the locking piece 4 is retracted from the pin hole 22, and the locking of the movable piece 2 and the claw 3 by the locking piece 4 can be released. At this time, under the action of the elastic force of the first elastic piece 5, the movable piece 2 is rotated in the opposite direction relative to the fixed piece 1, and the claw 3 is driven by the movable piece 2 to extend into the installation channel 21; or, the elastic force of the first elastic piece 5 directly acts on the claw 3, causing the claw 3 to extend into the installation channel 21 to fix the endoscope body.

[0053] That is to say, the endoscope body installation device provided in this embodiment uses the locking member 4 and the pin hole 22 to cooperate and limit, so as to realize the self-locking of the movable member 2 and the fixed member 1, so that the claw 3 is continuously kept in the open state, avoiding the situation in the prior art where the user continuously applies force to open the claw 3, which is equivalent to dividing the process of simultaneously applying force to open the claw 3 and installing the endoscope in the prior art into two different stages, that is, firstly, applying force to the movable member 2 to open the claw 3, limiting the position of the locking member 4 and the pin hole 22 to keep the claw 3 in the open state, and then installing the endoscope. The endoscope body is installed. The action of installing the endoscope body and the action of applying force to the movable part 2 are completed separately. The maintenance of the open state of the claws 3 is ensured by the self-locking achieved by the locking piece 4 and the pin hole 22. On the one hand, manpower is saved, and on the other hand, fatigue of the user caused by continuous force to open the claws 3 can be avoided. At the same time, the coordination requirement of the user to simultaneously exert force to continuously open the claws 3 and install the endoscope body is avoided, thereby ensuring the reliability of the installation of the endoscope body, preventing the endoscope body from being unable to be installed or falling off, and ensuring the safety of equipment and property.

[0054] It should be noted that the present embodiment does not limit the specific implementation method of retracting the locking member 4 from the pin hole 22 , as long as the locking member 4 can be retracted from the pin hole 22 when needed.

[0055] Considering the convenience of retracting the locking member 4 from the pin hole 22, please continue to refer to Figure 4 In some embodiments, the pin hole 22 is a through hole, and one end of the locking member 4 extends into the pin hole 22 and then extends into the mounting channel 21, so that when the endoscope body is inserted into the mounting channel 21, it is pushed by the endoscope body and retracted from the pin hole 22. That is, when the endoscope body is inserted into the mounting channel 21, the endoscope body can contact the locking member 4, so that when the endoscope body is installed into the mounting channel 21, the locking member 4 is pushed by the endoscope body to retract from the pin hole 22. It can be seen that in the present embodiment, the claw 3 can automatically reset and clamp the endoscope body as the endoscope body is inserted into the mounting channel 21, making the operation more convenient; moreover, the present embodiment eliminates the need to design other structures to allow the locking member 4 to retract from the pin hole 22, which helps to avoid the complexity of the overall structure; at the same time, it avoids the action of specifically retracting the locking member 4 from the pin hole 22, and the operation is simple; in addition, the locking member 4 extends out into the mounting channel 21 after being ejected into the pin hole 22, which also helps to improve the reliability of the claw 3 to continue to remain in the open state.

[0056] Of course, in other embodiments, the following scheme can also be adopted: the locking member 4 is provided with a reset button, and one end of the locking member 4 retracts from the pin hole 22 when the reset button is pressed. That is to say, in this embodiment, the locking member 4 is linked with the reset button, and when the reset button is pressed, the locking member 4 is actuated, so that one end of the locking member 4 retracts from the pin hole 22. That is, the claw 3 is unlocked only when the operator presses the reset button, so that the claw 3 clamps the endoscope body, and the installation of the endoscope body is completed. This is conducive to the operator confirming that the correct endoscope body is installed before operating the reset button, so that the endoscope body is clamped, thereby improving the correctness of the installation of the endoscope body.

[0057] It should be noted that the present embodiment does not limit the specific structure of the locking member 4 , as long as the locking member 4 has a telescopic function and can extend into the pin hole 22 when the pin hole 22 is aligned with one end of the locking member 4 , and can be retracted from the pin hole 22 .

[0058] Please refer to Figure 2 and Figure 4 Considering the simplicity of the structure and the convenience of implementation, in some embodiments, the locking member 4 includes a telescopic column 41 and a second elastic member 42. The telescopic column 41 is used to extend into the pin hole 22 or retract from the pin hole 22. The second elastic member 42 is arranged between the telescopic column 41 and the fixing member 1, and applies an elastic force to the telescopic column 41 to extend into the pin hole 22. That is, when the pin hole 22 is aligned with one end of the locking member 4, the telescopic column 41 is rebounded into the pin hole 22 under the action of the elastic force of the second elastic member 42. It can be understood that when the pin hole 22 is not aligned with one end of the locking member 4, the second elastic member 42 is in an elastic deformation state and has an elastic force. In this structural case, the telescopic column 41 is ejected into the pin hole 22 and then extends into the mounting channel 21, so that the telescopic column 41 is pushed by the endoscope body when the endoscope body is inserted into the mounting channel 21 and retracts from the pin hole 22. That is, when the endoscope body is inserted into the mounting channel 21, the endoscope body applies an extrusion force to the telescopic column 41, so that the telescopic column 41 squeezes the second elastic member 42, causing the second elastic member 42 to produce elastic deformation, thereby retracting the telescopic column 41 from the pin hole 22. The structure is simple and easy to implement, and has little effect on the overall structure of the endoscope body mounting device. The locking and unlocking of the claw 3 can be achieved by adding the telescopic column 41 and the second elastic member 42 without changing the overall structure of the endoscope body mounting device.

[0059] Of course, in other embodiments, the locking member 4 may be an elastic column with elasticity itself, or a spring sheet with a preset shape. When the pin hole 22 is aligned with one end of the locking member 4, under the elastic force of the elastic column or spring sheet itself, one end of the elastic column or spring sheet springs into the pin hole 22 to lock the claw 3; when a squeezing force is applied to the elastic column or spring sheet, so that one end of the elastic column or spring sheet retracts from the pin hole 22, the claw 3 is unlocked.

[0060] In other embodiments, the following scheme may be adopted: the locking member 4 includes a power element, and when the pin hole 22 is aligned with one end of the locking member 4, the power element is used to drive one end of the locking member 4 to extend into the pin hole 22; when the claw 3 needs to be unlocked, the power element is actuated to drive the locking member 4 to move in the opposite direction, so that the locking member 4 is retracted from the pin hole 22. This embodiment does not specifically limit the power element, as long as it can drive the locking member 4 to extend and retract.

[0061] Further, when the locking member 4 includes a telescopic column 41 and a second elastic member 42, please continue to refer to Figure 2 and Figure 4 In some embodiments, a universal ball 43 is embedded in one end of the telescopic column 41 facing the pin hole 22. It is understandable that when the pin hole 22 is aligned with the telescopic column 41, the pin hole 22 is aligned with the end of the telescopic column 41 where the universal ball 43 is located, and under the elastic force of the second elastic member 42, the telescopic column 41 drives the universal ball 43 to bounce into the pin hole 22. Since the universal ball 43 can roll in any direction relative to the end of the telescopic column 41, therefore, in the process of the movable part 2 rotating relative to the fixed part 1 and the claw 3 retracting, the telescopic column 41 is not aligned with the pin hole 22, and the universal ball 43 can roll along the physical structure of the movable part 2, so that there is rolling friction between the universal ball 43 and the movable part 2, and the friction force is small, so the wear of the universal ball 43 can be reduced, the reliability of the self-locking and unlocking functions can be improved, and the operation of the entire mechanism can be smoother and less noisy. In addition, when the universal ball 43 extends from the pin hole 22 into the installation channel 21, it is convenient to push the universal ball 43 from the installation channel 21, so that the universal ball 43 escapes from the pin hole 22. For example, when the endoscope body is installed into the installation channel 21, the endoscope body pushes the universal ball 43, so that the endoscope body generates a component force to squeeze the telescopic column 41 on the universal ball 43, so that the universal ball 43 escapes from the pin hole 22. Furthermore, the arrangement of the universal ball 43 also facilitates entering the pin hole 22.

[0062] Of course, in other embodiments, the following scheme can also be adopted: a spherical surface, an inclined surface or an arcuate surface is provided at one end of the telescopic column 41 facing the pin hole 22. That is to say, when the telescopic column 41 is ejected into the pin hole 22, the end of the spherical surface, the inclined surface or the arcuate surface of the telescopic column 41 enters the pin hole 22, and the spherical surface, the inclined surface or the arcuate surface has a guiding function, making it easier for the end of the telescopic column 41 to enter the pin hole 22. Moreover, in the process that the movable part 2 rotates relative to the fixed part 1 and the claw 3 retracts, the telescopic column 41 is not aligned with the pin hole 22, and the spherical surface, the inclined surface or the arcuate surface can slide along the physical structure of the movable part 2, and the contact area between the movable part 2 and the movable part 2 is small, and the friction force is small. In addition, when the spherical surface, inclined surface or curved surface extends from the pin hole 22 into the installation channel 21, during the process of the endoscope body being installed into the installation channel 21, the endoscope body pushes the spherical surface, inclined surface or curved surface, which can generate a component force on the telescopic column 41 along the axial direction of the telescopic column 41, making it convenient to retract the telescopic column 41 from the pin hole 22 under the pushing action of the endoscope body.

[0063] In addition, if Figure 4 and Figure 5 As shown, in some embodiments, the locking member 4 is provided with a guide limiting hole 441, and the telescopic column 41 and the second elastic member 42 are arranged in the guide limiting hole 441. That is, when the telescopic column 41 is ejected into or retracted from the pin hole 22, the telescopic column 41 and the second elastic member 42 are telescoped along the guide limiting hole 441, and the guide limiting hole 441 defines the telescopic direction of the telescopic column 41 and the second elastic member 42, thereby ensuring the reliability of the telescopic column 41. In addition, after the telescopic column 41 is ejected into the pin hole 22, the guide limiting hole 441 also has a limiting effect on the telescopic column 41 and the second elastic member 42, thereby preventing the telescopic column 41 and the second elastic member 42 from being skewed, etc., thereby ensuring the reliability of the telescopic column 41 and the pin hole 22 in the cooperation and limiting.

[0064] In addition, please continue to refer to Figure 4 and Figure 5 In order to prevent the telescopic column 41 from entering the pin hole 22 too long, in some embodiments, the guide limit hole 441 is a stepped hole, and a limit portion 411 is provided at one end of the telescopic column 41 facing the second elastic member 42, and the limit portion 411 is used to cooperate with the step surface 442 of the stepped hole for limiting. That is, when the telescopic column 41 is ejected into the pin hole 22 under the elastic force of the second elastic member 42, when the limit portion 411 contacts the step surface 442 of the stepped hole, it indicates that the telescopic column 41 is ejected into place, and under the stopping action of the step surface 442 of the stepped hole, the telescopic column 41 cannot be ejected further, which is conducive to ensuring that the telescopic column 41 is ejected into the pin hole 22 to a suitable length.

[0065] Further, in order to facilitate the connection between the locking member 4 and the fixing member 1, in some embodiments, the locking member 4 includes a fixing seat 44, the fixing seat 44 is fixedly connected to the fixing member 1, and the telescopic column 41 and the second elastic member 42 are installed on the fixing seat 44. In this embodiment, the connection between the locking member 4 and the fixing member 1 is achieved by means of the fixing seat 44. During assembly, the telescopic column 41 and the second elastic member 42 can be first installed on the fixing seat 44 so that the three form an integral component, and then the integral component is fixed to the fixing member 1 through the fixing seat 44, so as to facilitate the installation of the locking member 4. Further, in this embodiment, the specific structure of the fixing seat 44 is not limited, as long as the fixing seat 44 can be provided with the locking member 4. In some embodiments, the fixing seat 44 is an arc-shaped block so that the fixing seat 44 can better fit the annular fixing member 1, so that the connection between the fixing seat 44 and the fixing member 1 is more stable and reliable.

[0066] It should be noted that the embodiments of the utility model do not limit the specific connection method between the fixing seat 44 and the fixing member 1. In some embodiments, the fixing seat 44 and the fixing member 1 are connected by fasteners.

[0067] In some embodiments, the pin hole 22 is disposed on the circumferential side wall of the movable part 2 around the mounting channel 21; or the pin hole 22 is disposed on the bottom wall of the movable part 2 facing the insertion end of the endoscope body. It is understandable that the position of the locking member 4 corresponds to the position of the pin hole 22. When the setting position of the pin hole 22 is adjusted, the position of the locking member 4 will also be adaptively adjusted. At the same time, in order to facilitate the setting of the locking member 4, other corresponding structures will also be adaptively adjusted. When the pin hole 22 is disposed on the circumferential side wall of the movable part 2 around the mounting channel 21, the structure of the locking member 4 and the slide groove 23 circumferentially surrounds the movable part 2, so that the entire device expands the radial size and saves the axial size. When the pin hole 22 is arranged on the bottom wall of the movable part 2 facing the insertion end of the endoscope body, the locking part 4, the slide groove 23, etc. are to be arranged in the direction of the bottom wall of the corresponding movable part 2, so that the entire device expands the axial size and saves the radial size, and when the locking part 4 is retracted from the pin hole 22 by relying on the resistance of the endoscope body, the claw 3 is extended into the installation channel 21 when the end face of the insertion end of the endoscope body is installed in place, which has higher reliability.

[0068] In addition, in some embodiments, the movable member 2 is provided with a slide groove 23, the locking member 4 is embedded in the slide groove 23, and the locking member 4 and the slide groove 23 can slide relative to each other. It can be understood that the locking member 4 is embedded in the slide groove 23, and the slide groove 23 is used to accommodate at least part of the structure of the locking member 4, so that the locking member 4 and the movable member 2 have an overlapping space, thereby reducing the overall volume of the entire device. In addition, the locking member 4 and the slide groove 23 can slide relative to each other, and the locking member 4 limits the sliding trajectory of the slide groove 23, that is, it limits the trajectory of the movable member 2 rotating relative to the fixed member 1, thereby improving the movement reliability.

[0069] In addition, it should be noted that the first elastic member 5 can be installed between the fixed member 1 and the movable member 2, or between the clamping claw 3 and the fixed member 1 or between the clamping claw 3 and the movable member 2, as long as a force can be provided to directly or indirectly force the clamping claw 3 to extend. In the prior art, there are many feasible installation methods for the first elastic member 5, which will not be described here.

[0070] In some embodiments, the first elastic member 5 is embedded in the slide groove 23, and one end of the first elastic member 5 is fixedly connected to the locking member 4, and the other end is fixedly connected to the movable member 2. It can be understood that the first elastic member 5 is embedded in the slide groove 23, and the slide groove 23 is used to accommodate the first elastic member 5, so that the first elastic member 5 and the movable member 2 have an overlapping space, thereby further reducing the overall volume of the entire device. In addition, the slide groove 23 is used to limit the first elastic member 5, so that the first elastic member 5 is extended along the direction defined by the slide groove 23, thereby ensuring the reliability of the extension of the first elastic member 5 and avoiding the first elastic member 5 from being skewed during the extension process. In addition, since the locking member 4 and the first elastic member 5 are both embedded in the slide groove 23, therefore, one end of the first elastic member 5 is fixedly connected to the locking member 4, and the first elastic member 5 is also indirectly connected to the fixed member 1, and the other end of the first elastic member 5 is fixedly connected to the movable member 2, so that the first elastic member 5 can apply a certain elastic force to the relative movement of the fixed member 1 and the movable member 2, and the elastic force indirectly acts on the claw 3, so that the claw 3 extends into the installation channel 21.

[0071] Furthermore, the above embodiments do not limit the specific structure of the first elastic member 5, as long as the first elastic member 5 can apply a certain elastic force to the relative movement of the fixed member 1 and the movable member 2 or apply an elastic force to the claw 3. In some embodiments, the first elastic member 5 is a spring, and the movable member 2 is provided with a column 26, and the column 26 is inserted into the gap at one end of the spring 5. It can be understood that the structure of the spring is simple and convenient to set up; in this embodiment, by setting the column 26 on the movable member 2, the column 26 is inserted into the gap at one end of the spring 5, so that one end of the spring is fixedly connected to the movable member 2. In some embodiments, the locking member 4 is fixed to the fixing member 1 by a fastener, and at the same time, the fastener is inserted into the gap at the other end of the spring 5. That is to say, in this embodiment, while the fastener is used to fix the locking member 4 and the fixing member 1, the fastener is used to fix the spring and the locking member 4. The structure is simple and the connection structure is simplified.

[0072] In addition, in order to facilitate the application of external force to rotate the movable part 2 relative to the fixed part 1, in some embodiments, an operating handle is provided on the outer wall of the fixed part 1 and / or the movable part 2. For the convenience of description, the operating handle of the fixed part 1 is referred to as the first operating handle 12, and the operating handle of the movable part 2 is referred to as the second operating handle 25. When installing the endoscope body, the operator manually grasps and pushes or pulls the first operating handle 12 and / or the second operating handle 25 to rotate the movable part 2 relative to the fixed part 1, thereby causing the movable part 2 to drive the claw 3 to retract from the installation channel 21 until the locking part 4 extends into the pin hole 22, so that the claw 3 is in an open state; in this process, the first elastic part 5 undergoes elastic deformation and stores elastic energy. When the locking part 4 retracts from the pin hole 22, under the elastic force of the first elastic part 5, the movable part 2 rotates in the opposite direction relative to the fixed part 1, so that the claw 3 extends into the installation channel 21 to clamp the endoscope body. It can be seen that the provision of the operating handle facilitates the application of external force to the movable part 2 and / or the fixed part 1 so as to make the movable part 2 rotate relative to the fixed part 1 .

[0073] Furthermore, in some embodiments, the fixed member 1 is provided with a strip groove 13 along the circumferential direction, the movable member 2 is embedded in the fixed member 1, and the operating handle of the movable member 2 (i.e., the second operating handle 25) passes through the strip groove 13. It is understandable that the movable member 2 is embedded in the fixed member 1, so that the movable member 2 and the fixed member 1 have at least a partially overlapping space in the axial direction, which is conducive to saving the axial dimension. In addition, the second operating handle 25 passes through the strip groove 13 on the fixed member 1, which is convenient for operating the second operating handle 25 on the one hand, and is conducive to making the second operating handle 25 and the first operating handle 12 have a suitable relative position for convenient operation on the other hand. It is understandable that there is a movable gap between the second operating handle 25 and the strip groove 13, so that the second operating handle 25 can move in the strip groove 13 when the user operates the second operating handle 25.

[0074] In addition, the embodiment of the utility model does not limit the connection method of the claw 3 with the movable part 2 and the fixed part 1 respectively, as long as the claw 3 can be movably installed between the fixed part 1 and the movable part 2, when the movable part 2 rotates relative to the fixed part 1, it can be extended into the installation channel 21 or retracted from the installation channel 21. In the prior art, there are many feasible installation methods for the claw 3, which will not be described here. Figure 7 and Figure 8In some embodiments, the claw 3 is provided with a rotating shaft 31 and a limiting column 32, the movable part 2 is provided with a rotating shaft hole 24, the rotating shaft 31 is rotatably connected to the rotating shaft hole 24, the fixed part 1 is provided with a guide groove 11, and the limiting column 32 is arranged in the guide groove 11 and can slide along the guide groove 11. When the movable part 2 rotates relative to the fixed part 1, the claw 3 is driven to rotate with the movable part 2 while rotating relative to the movable part 2 around the rotating shaft 31. At this time, the limiting column 32 slides in the guide groove 11, and under the limitation of the guide groove 11, the claw 3 is extended into the installation channel 21 or retracted from the installation channel 21, so that the claw 3 clamps or releases the endoscope body.

[0075] It should be noted that the embodiment of the utility model does not limit the specific number of the claws 3, and those skilled in the art can set it according to actual needs. In some embodiments, the number of the claws 3 is at least three, and all the claws 3 are evenly distributed along the circumference of the movable part 2.

[0076] In addition, it should be noted that in addition to the shape of the claw 3, the structural shape of other parts cooperating with the claw 3, the shape of the first elastic member 5, and the structural shape of other parts cooperating with the first elastic member 5 given in the accompanying drawings of the embodiment of the utility model, there are other feasible implementation methods in the prior art, which are not listed in detail here.

[0077] In addition, the embodiments of the present invention do not limit the specific structures of the fixing member 1 and the movable member 2. In some embodiments, the fixing member 1 is a circular ring-shaped fixing member, and the movable member 2 is a circular ring-shaped movable member.

[0078] In addition to the above-mentioned endoscope body mounting device, the present invention also provides an endoscope system, including an endoscope and the endoscope body mounting device disclosed in the above-mentioned embodiment, the endoscope body of the endoscope is inserted into the mounting channel 21 of the endoscope body mounting device and clamped by the claw 3. The structures of other parts of the endoscope system are referred to the prior art and will not be described in detail herein.

[0079] The focus of this embodiment is to adopt the endoscope body installation device disclosed in the above-mentioned embodiment. Since the above-mentioned endoscope body installation device utilizes the locking part 4 and the pin hole 22 to cooperate and limit, the movable part 2 and the fixed part 1 are self-locked, so that the claw 3 is continuously kept in the open state. Therefore, when installing the endoscope, the user does not need to continuously apply force to open the claw 3, which facilitates the installation of the endoscope, saves manpower, and ensures the reliability of the endoscope installation.

[0080] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
