Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an endoscope body installation device. In addition, the present invention also relates to an endoscope system including the above-mentioned endoscope body installation device. Background Art

[0002] Endoscope systems are widely used in clinical surgeries. For example, laparoscopes, as a type of endoscope, are used in minimally invasive abdominal surgeries. They enter the human body through a surgical incision in a sterile environment to diagnose the internal conditions of the human body and complete examinations, diagnoses, and treatments.

[0003] The existing endoscope systems in the prior art include an endoscope and an optical bayonet. The endoscope is inserted into the optical bayonet, and the optical bayonet uses the spring force to clamp the endoscope with a claw. During installation, by applying manual external force to the handle on the optical bayonet, the handle drives the claw to open, and by continuously grasping the handle with force, the claw is kept in an open state. Then, the eyepiece cover of the endoscope is inserted into the optical bayonet, and then the handle is released, and the handle drives the claw to tighten and reset under the action of the spring force to clamp the endoscope.

[0004] That is to say, when assembling the endoscope and the optical bayonet, the operator needs to continuously apply force to the handle with one hand to overcome the spring force, and at the same time use the other hand to install the endoscope. The installation is inconvenient and requires high coordination of the operator. Moreover, in order to make the claw have sufficient clamping force on the endoscope, the spring force is relatively large. Therefore, the driving force of the operator on the handle is relatively large, and continuous single-handed force application for a long time is likely to cause fatigue, and there is a risk that the endoscope cannot be installed or drops.

[0005] Therefore, how to avoid the continuous force application of the operator during the installation of the endoscope is an urgent problem to be solved by those skilled in the art at present. Summary of the Invention

[0006] In view of this, an object of the present invention is to provide an endoscope body installation device that can avoid the continuous force application of the operator during the installation of the endoscope.

[0007] Another object of the present invention is to provide an endoscope system including the above-mentioned endoscope body installation device, which is convenient for installing the endoscope.

[0008] In order to achieve the above objects, the present invention provides the following technical solutions:

[0009] An endoscope body installation device having an installation channel for inserting and installing an endoscope body, comprising:

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

[0011] The movable part is rotatably connected to the fixed part, can rotate around the installation channel, and is provided with a pin hole thereon;

[0012] The claw is movably installed between the fixed part and the movable part. When the movable part rotates relative to the fixed part, it extends into or retracts from the installation channel to fix or release the endoscope body;

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

[0014] The locking member is fixedly arranged on the fixed part and has a telescopic function. When the movable part rotates relative to the fixed part to a set position, the pin hole is aligned with one end of the locking member, and the locking member extends into the pin hole to stop the movable part from rotating relative to the fixed part and limit the claw at a retracted position allowing the installation and disassembly of the endoscope body; when the locking member retracts from the pin hole, the locking of the movable part and the claw is released.

[0015] Optionally, the pin hole is a through hole, and one end of the locking member extends into the pin hole and extends out of the installation channel, so as to be pushed by the endoscope body to retract from the pin hole when the endoscope body is inserted into the installation channel.

[0016] Optionally, the locking member includes:

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

[0018] The second elastic member is arranged between the telescopic column and the fixed part and applies an elastic force to the telescopic column to extend into the pin hole.

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

[0020] Alternatively, a spherical surface, an inclined surface or an arc surface is provided at one end of the telescopic column facing the pin hole.

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

[0022] Optionally, the guiding and 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 for cooperating with the stepped surface of the stepped hole for limiting.

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

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

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

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

[0027] Optionally, the first elastic member is a spring, and the movable member is provided with a column, and the column is snapped into 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 operation handle is provided on the outer wall of the fixing member and / or the movable member.

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

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

[0032] When installing the endoscope body with the endoscope body mounting device provided by the present invention, by applying an external force to rotate the movable member relative to the fixing member. At this time, the claw moves between the movable member and the fixing member under the drive of the movable member, and then retracts from the installation channel. During the process of the claw retracting from the installation channel, the pin hole is not aligned with the locking member. When the movable member rotates relative to the fixing member to a set position, the pin hole is aligned with one end of the locking member. At this time, the locking member extends into the pin hole, and by using the limiting effect of the pin hole on the locking member, the relative fixation of the fixing member and the movable member is realized, so that the movable member stops rotating relative to the fixing member. At this time, the movable member cannot drive the claw to move, so that the claw 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 then inserted into the installation channel. When the endoscope body is inserted into the installation channel in place, the locking member is retracted from the pin hole, then the locking of the locking member on the movable member and the claw can be released. At this time, under the action of the elastic force of the first elastic member, the movable member rotates in the opposite direction relative to the fixing member, and then the claw extends into the installation channel under the drive of the movable member; or, the elastic force of the first elastic member directly acts on the claw to make the claw extend into the installation channel to fix the endoscope body.

[0033] That is, the present invention utilizes the cooperation and limitation of the locking member and the pin hole to achieve self-locking of the movable member and the fixed member, so that the claw is continuously maintained in an open state, avoiding the situation in the prior art where the user continuously applies force to open the claw. This is equivalent to dividing the process of simultaneously applying force to open the claw and installing the endoscope body in the prior art into two different stages. That is, first, apply force to the movable member to open the claw, use the locking member and the pin hole for limitation, and maintain the open state of the claw. Then, install the endoscope body. The action of installing the endoscope body is completed separately from the action of applying force to the movable member. The maintenance of the open state of the claw is ensured by the self-locking achieved by the cooperation of the locking member and the pin hole. On the one hand, it saves manpower. On the other hand, it can avoid the user's fatigue caused by continuously applying force to open the claw, and at the same time avoid the coordination requirement for the user to simultaneously apply force to keep the claw continuously open and install the endoscope, 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 safety of equipment and property.

[0034] The endoscope system provided by the present invention includes the above-mentioned endoscope body installation device and has the above-mentioned beneficial effects. Brief Description of the Drawings

Specific embodiments

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0049] The core of the present invention is to provide an endoscope body installation device, which can avoid continuous force application by the operator during endoscope installation. Another core of the present invention is to provide an endoscope system including the above endoscope body installation device, which is convenient for endoscope installation.

[0050] Please refer to Figures 1 - 4, an embodiment of the present invention provides an endoscope body mounting device, which has a mounting channel 21 for inserting and mounting an endoscope body. The endoscope body mounting device includes a fixing member 1, a movable member 2, a claw 3, a first elastic member 5, and a locking member 4. The fixing member 1 is disposed on the outer periphery of the mounting channel 21; the movable member 2 is rotatably connected to the fixing member 1, and the movable member 2 can rotate around the mounting channel 21. A pin hole 22 is provided on the movable member 2; the claw 3 is movably mounted between the fixing member 1 and the movable member 2. When the movable member 2 rotates relative to the fixing member 1, the claw 3 extends into the mounting channel 21 or retracts from the mounting channel 21 to fix or release the endoscope body; the first elastic member 5 provides a force to drive the movable member 2 to rotate in the reverse direction or provides a force for the claw 3 to extend into the mounting channel 21 when the movable member 2 is rotated by an external force; the locking member 4 is disposed on the fixing member 1 and has a telescopic function. When the movable member 2 rotates relative to the fixing member 1 to a set position, 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 to stop the movable member 2 from rotating relative to the fixing member 1 and limit the claw 3 to a retracted position allowing the installation and disassembly of the endoscope body; when the locking member 4 retracts from the pin hole 22, the locking of the movable member 2 and the claw 3 is released.

[0051] It should be noted that when the claw 3 extends into the mounting channel 21, it can clamp the endoscope body and play a role in fixing the endoscope body; when the claw 3 retracts from the mounting channel 21, that is, when the claw 3 opens, the endoscope body is released. At this time, the endoscope body can be removed from the mounting channel 21; at the same time, when the claw 3 opens, it is also convenient to install the endoscope body.

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

[0053] That is to say, for the endoscope body installation device provided in this embodiment, the locking member 4 and the pin hole 22 are used in cooperation for limiting, so as to realize the self-locking of the movable member 2 and the fixed member 1, and keep the claw 3 in an open state continuously. This avoids the situation in the prior art where the user continuously applies force to open the claw 3. This is equivalent to dividing the process of simultaneously applying force to open the claw 3 and install the endoscope in the prior art into two different stages. That is, first, apply force to the movable member 2 to open the claw 3, use the locking member 4 and the pin hole 22 for limiting, and keep the claw 3 in an open state. Then install the endoscope body. The action of installing the endoscope body is completed separately from the action of applying force to the movable member 2. The maintenance of the open state of the claw 3 is ensured by the self-locking realized by the cooperation of the locking member 4 and the pin hole 22. On the one hand, it saves manpower. On the other hand, it can avoid the user's fatigue caused by continuously applying force to open the claw 3, and at the same time avoid the coordination requirement for the user to simultaneously apply force to keep the claw 3 open continuously and install the endoscope body, ensure the reliability of the endoscope body installation, prevent the endoscope body from being unable to be installed or falling off, and ensure the safety of equipment and property.

[0054] It should be noted that this embodiment does not limit the specific implementation manner 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 realizing the retraction of 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 out into the installation channel 21, so as to be pushed by the endoscope body to retract from the pin hole 22 when the endoscope body is inserted into the installation channel 21. That is to say, when the endoscope body is inserted into the installation channel 21, the endoscope body can touch the locking member 4, so that during the process of loading the endoscope body into the installation channel 21, the endoscope body is used to push the locking member 4 to make the locking member 4 retract from the pin hole 22. It can be seen that in this embodiment, the claw 3 can automatically reset and clamp the endoscope body as the endoscope body is inserted into the installation channel 21, making the operation more convenient; moreover, this embodiment eliminates the need to design other structures to retract the locking member 4 from the pin hole 22, which is beneficial to avoiding the complexity of the overall structure; at the same time, it avoids the special action of retracting the locking member 4 from the pin hole 22, and the operation is simple; in addition, after the locking member 4 snaps into the pin hole 22 and extends out into the installation channel 21, it is also beneficial to improve the reliability of the claw 3 to continuously maintain an open state.

[0056] Of course, in some other embodiments, the following solution may also be adopted: The locking member 4 is provided with a reset button. When the reset button is pressed, one end of the locking member 4 retracts from the pin hole 22. That is to say, in this embodiment, the locking member 4 is linked with the reset button. When the reset button is pressed, the locking member 4 acts, causing one end of the locking member 4 to retract from the pin hole 22. That is, only when the operator presses the reset button can the claw 3 be unlocked, so that the claw 3 can hold the endoscope body, completing the installation of the endoscope body. This is conducive to enabling the operator to confirm that the correct endoscope body is installed before operating the reset button, and then hold the endoscope body, improving the correctness of the installation of the endoscope body.

[0057] It should be noted that the specific structure of the locking member 4 in this embodiment is not limited. 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 retract from the pin hole 22, it is sufficient.

[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, applying an elastic force to the telescopic column 41 to extend into the pin hole 22. That is to say, when the pin hole 22 is aligned with one end of the locking member 4, under the action of the elastic force of the second elastic member 42, the telescopic column 41 pops into the pin hole 22. 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 elastically deformed state and has an elastic force. In this case, after the telescopic column 41 pops into the pin hole 22 and extends out of the installation channel 21, the telescopic column 41 can be pushed by the endoscope body and retract from the pin hole 22 when the endoscope body is inserted into the installation channel 21. That is, when the endoscope body is inserted into the installation channel 21, the endoscope body applies a squeezing force to the telescopic column 41, thereby causing the telescopic column 41 to squeeze the second elastic member 42, causing the second elastic member 42 to produce elastic deformation, and thus the telescopic column 41 can retract from the pin hole 22. This structure is simple and convenient to implement, has little impact on the overall structure of the endoscope body installation device, and can lock and unlock the claw 3 by adding the telescopic column 41 and the second elastic member 42 without changing the overall structure of the endoscope body installation device.

[0059] Of course, in some other embodiments, the locking member 4 can be an elastic column with its own elasticity or a spring piece with a preset shape. When the pin hole 22 is aligned with one end of the locking member 4, one end of the elastic column or the spring piece pops into the pin hole 22 under the action of its own elastic force, realizing the locking of the claw 3; when a squeezing force is applied to the elastic column or the spring piece to cause one end of the elastic column or the spring piece to retract from the pin hole 22, the locking of the claw 3 is released.

[0060] In some other embodiments, the following solution may also be adopted: The locking member 4 includes a power element. 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 it is necessary to unlock the claw 3, the power element acts to drive the locking member 4 to move in the opposite direction, so that the locking member 4 retracts from the pin hole 22. In this embodiment, the power element is not specifically limited as long as it can drive the locking member 4 to expand and contract.

[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 at one end of the telescopic column 41 facing the pin hole 22. It can be understood 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. 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 together. Since the universal ball 43 can roll in any direction relative to the end of the telescopic column 41, during the process of the movable member 2 rotating relative to the fixed member 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 solid structure of the movable member 2, so that the friction between the universal ball 43 and the movable member 2 is rolling friction, and the friction force is small. Therefore, 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 is smoother and the noise is small. In addition, when the universal ball 43 extends into the installation channel 21 from the pin hole 22, it is beneficial to push the universal ball 43 from the inside of the installation channel 21, so that the universal ball 43 can be disengaged from the pin hole 22. For example, during the process of inserting the endoscope body into the installation channel 21, by using the endoscope body to push against the universal ball 43, a component force for squeezing the telescopic column 41 can be generated on the universal ball 43 by the endoscope body, so that the universal ball 43 can be disengaged from the pin hole 22. Further, the setting of the universal ball 43 also facilitates entering the pin hole 22.

[0062] Of course, in some other embodiments, the following solutions may also be adopted: the end of the telescopic column 41 facing the pin hole 22 is provided with a spherical surface, an inclined surface or an arc surface. That is to say, when the telescopic column 41 pops into the pin hole 22, the end of the spherical surface, inclined surface or arc surface of the telescopic column 41 enters the pin hole 22. The spherical surface, inclined surface or arc surface has a guiding effect, making it easier for this end of the telescopic column 41 to enter the pin hole 22. Moreover, during the rotation of the movable member 2 relative to the fixed member 1 and the retraction of the claw 3, the telescopic column 41 is not aligned with the pin hole 22. The spherical surface, inclined surface or arc surface can slide along the solid structure of the movable member 2, with a small contact area and small friction between them. In addition, when the spherical surface, inclined surface or arc surface extends into the installation channel 21 from the pin hole 22, during the process of inserting the endoscope body into the installation channel 21, the endoscope body pushes against the spherical surface, inclined surface or arc surface, which can generate a component force along the axial direction of the telescopic column 41 on the telescopic column 41, facilitating the retraction of the telescopic column 41 from the pin hole 22 under the pushing action of the endoscope body.

[0063] In addition, as Figure 4 and Figure 5 shown, in some embodiments, the locking member 4 is provided with a guiding and limiting hole 441, and the telescopic column 41 and the second elastic member 42 are arranged in the guiding and limiting hole 441. That is to say, when the telescopic column 41 pops into or retracts from the pin hole 22, the telescopic column 41 and the second elastic member 42 expand and contract along the guiding and limiting hole 441. The guiding and limiting hole 441 defines the expansion and contraction direction of the telescopic column 41 and the second elastic member 42, ensuring the reliability of the expansion and contraction of the telescopic column 41. In addition, after the telescopic column 41 pops into the pin hole 22, the guiding and limiting hole 441 also has a limiting effect on the telescopic column 41 and the second elastic member 42, which can prevent the telescopic column 41 and the second elastic member 42 from being skewed, etc., ensuring the reliability of the cooperation and limitation between the telescopic column 41 and the pin hole 22.

[0064] In addition, please continue to refer to Figure 4 and Figure 5 , in order to prevent the length of the telescopic column 41 entering the pin hole 22 from being too long, in some embodiments, the guiding and limiting hole 441 is a stepped hole, and the end of the telescopic column 41 facing the second elastic member 42 is provided with a limiting portion 411, and the limiting portion 411 is used to cooperate with the step surface 442 of the stepped hole for limiting. That is to say, when the telescopic column 41 pops into the pin hole 22 under the elastic force of the second elastic member 42, when the limiting portion 411 contacts the step surface 442 of the stepped hole, it indicates that the telescopic column 41 pops into place. Under the blocking action of the step surface 442 of the stepped hole, the telescopic column 41 cannot pop in further, which is beneficial to ensuring that the telescopic column 41 pops into the pin hole 22 with an appropriate 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 embodiment of the present invention does 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 claw 3 and the fixed member 1 or between the claw 3 and the movable member 2, as long as it can provide a force to directly or indirectly force the claw 3 to extend. In the prior art, there are various feasible installation methods for the first elastic member 5, which will not be elaborated here.

[0070] In some embodiments, the first elastic member 5 is embedded in the sliding groove 23, and one end thereof 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 sliding groove 23, and the sliding 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 sliding groove 23 is used to limit the first elastic member 5, so that the first elastic member 5 expands and contracts along the direction defined by the sliding groove 23, thereby ensuring the reliability of the expansion and contraction of the first elastic member 5 and avoiding the skew of the first elastic member 5 during the expansion and contraction process. In addition, since both the locking member 4 and the first elastic member 5 are embedded in the sliding groove 23, therefore, fixedly connecting one end of the first elastic member 5 to the locking member 4 also indirectly connects the first elastic member 5 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 exert a certain elastic force on the relative movement of the fixed member 1 and the movable member 2, and this elastic force indirectly acts on the claw 3 to realize the claw 3 extending into the installation channel 21.

[0071] Furthermore, the specific structure of the first elastic member 5 is not limited in the above embodiments, as long as the first elastic member 5 can exert a certain elastic force on the relative movement of the fixed member 1 and the movable member 2 or exert an elastic force on 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 clamped 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; in this embodiment, by providing the column 26 on the movable member 2 and clamping the column 26 into the gap at one end of the spring 5, the connection between one end of the spring and the movable member 2 is realized. In some embodiments, the locking member 4 is fixed to the fixed member 1 through a fastener, and at the same time, the fastener is clamped into the gap at the other end of the spring 5. That is to say, in this embodiment, while using the fastener to fix the locking member 4 and the fixed member 1, the fastener is used to realize the fixation of the spring and the locking member 4, and this structure is simple and simplifies the connection structure.

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

[0073] Further, in some embodiments, the fixed member 1 is provided with a strip-shaped groove 13 along the circumferential direction. The movable member 2 is embedded in the fixed member 1, and the operation handle of the movable member 2 (i.e., the second operation handle 25) passes through the strip-shaped groove 13. It can be understood 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 partially overlapping spaces in the axial direction, which is beneficial to saving the axial dimension. In addition, the second operation handle 25 passes out of the strip-shaped groove 13 on the fixed member 1. On the one hand, it is convenient to operate the second operation handle 25. On the other hand, it is beneficial to make the second operation handle 25 have a suitable relative position with the first operation handle 12 for convenient operation. It can be understood that there is an activity gap between the second operation handle 25 and the strip-shaped groove 13, so that when the user operates the second operation handle 25, the second operation handle 25 can move in the strip-shaped groove 13.

[0074] In addition, the embodiments of the present invention do not limit the connection methods of the claw 3 with the movable member 2 and the fixed member 1 respectively. As long as the claw 3 can be movably installed between the fixed member 1 and the movable member 2 and can extend into or retract from the installation channel 21 when the movable member 2 rotates relative to the fixed member 1, in the prior art, there are various feasible installation methods for the claw 3, which will not be elaborated here. Please refer to Figure 7 and Figure 8, in some embodiments, the jaw 3 is provided with a rotating shaft 31 and a limiting post 32, the movable member 2 is provided with a rotating shaft hole 24, the rotating shaft 31 is rotatably connected to the rotating shaft hole 24, the fixing member 1 is provided with a guiding groove 11, and the limiting post 32 is arranged in the guiding groove 11 and can slide along the guiding groove 11. When the movable member 2 rotates relative to the fixing member 1, it drives the jaw 3 to rotate along with the movable member 2 and rotate relative to the movable member 2 around the rotating shaft 31. At this time, the limiting post 32 slides in the guiding groove 11, and under the limitation of the guiding groove 11, the jaw 3 extends into or retracts from the installation channel 21, realizing clamping or loosening of the endoscope body by the jaw 3.

[0075] It should be noted that the specific number of the jaws 3 in the embodiments of the present invention is not limited, and those skilled in the art can set it according to actual needs. In some embodiments, the number of the jaws 3 is at least three, and all the jaws 3 are evenly distributed along the circumferential direction of the movable member 2.

[0076] In addition, it should be noted that in addition to the shape of the jaw 3 shown in the accompanying drawings of the embodiments of the present invention, the structural shapes of other parts cooperating with the jaw 3, the shape of the first elastic member 5, and the structural shapes of other parts cooperating with the first elastic member 5, there are other feasible implementation manners in the prior art, which will not be listed in detail here.

[0077] In addition, the specific structures of the fixing member 1 and the movable member 2 in the embodiments of the present invention are not limited. In some embodiments, the fixing member 1 is an annular fixing member, and the movable member 2 is an annular movable member.

[0078] In addition to the above endoscope body installation device, the present invention also provides an endoscope system, including an endoscope and the endoscope body installation device disclosed in the above embodiments. The endoscope body of the endoscope is inserted into the installation channel 21 of the endoscope body installation device and is clamped by the jaws 3. For the structures of other parts of this endoscope system, please refer to the prior art and will not be elaborated herein.

[0079] The key point of this embodiment is to adopt the endoscope body installation device disclosed in the above embodiments. Since the above endoscope body installation device uses the locking member 4 and the pin hole 22 to cooperate for limiting, realizing the self-locking of the movable member 2 and the fixing member 1, and keeping the jaws 3 in an open state continuously, therefore, when installing the endoscope, it is not necessary for the user to continuously apply force to open the jaws 3, which is convenient for the installation of the endoscope, saves manpower, and ensures the reliability of the endoscope installation.
