Abstract

The utility model relates to an endoscope in-place detection mechanism, a system host of an endoscope system and the endoscope system. On the basis of the application, the translation component can be arranged on the endoscope tube bayonet socket of the system host of the endoscope system, and the sensing assembly for generating the sensing signal according to the position of the translation component is arranged. Wherein the translation component can generate translation displacement of a preset displacement stroke in the period that the endoscope tube connector of the endoscope is inserted into the endoscope tube inserting seat, and the translation component can also respond to pulling out of the endoscope tube connector from the endoscope tube inserting seat to automatically return. Therefore, the signal state of the induction signal generated by the induction assembly can be dynamically changed along with translation displacement and automatic return of the translation component so as to represent whether the endoscope is in the in-place state that the endoscope tube connector is inserted into the endoscope tube inserting seat or not, and then automatic detection on whether the endoscope is in place or not is achieved.

Description

Technical Field

[0001] This application relates to endoscope technology, and particularly to an in-situ detection mechanism for an endoscope, a system host of an endoscope system, and an endoscope system. Background Art

[0002] An endoscope system may include an endoscope and a system host. Among them, the front end of the endoscope tube has a front end lens, and the front end lens of the endoscope can enter the target internal tissue in the human body through the natural cavity or surgical incision of the human body, so that the target internal tissue can be imaged through the endoscope lens. The end of the endoscope tube has a tube connector, and the system host has a tube socket. Thus, when the tube connector of the endoscope is plugged into the tube socket of the system host, the system host can obtain the image data of the target internal tissue imaged through the endoscope lens.

[0003] For surgical needs, a light source module may also be arranged inside the system host, and the light source module can generate a surgical auxiliary light beam when starting and operating. In this case, a light source module for generating a surgical auxiliary light beam can be arranged in the system host, and a light transmission opening for emitting the surgical auxiliary light beam is provided on the tube socket of the device host. Thus, when the tube connector of the endoscope is plugged into the tube socket of the system host, the surgical auxiliary light beam emitted from the light transmission opening of the tube socket can enter the endoscope from the tube connector and be conducted to the front end of the endoscope tube and emitted. For example, the surgical auxiliary light beam may include an illumination light beam, and the illumination light beam emitted from the front end of the endoscope tube can irradiate the target internal tissue to increase the environmental brightness of the internal environment of the human body where the target internal tissue is located, thereby improving the imaging effect of the target internal tissue.

[0004] However, the system host of the endoscope system cannot automatically detect whether the endoscope is in the in-situ state (i.e., whether the tube connector is plugged into the tube socket). Therefore, it is possible that the system host starts the light source module when the endoscope is not in the in-situ state (i.e., the tube connector is not plugged into the tube socket). If so, the surgical auxiliary light beam will be directly emitted from the light transmission opening of the tube socket to the scene environment where the system host is located, thereby causing light pollution to the scene environment where the system host is located and even possibly causing harm to the personnel in the scene environment.

[0005] It can be seen that how to automatically detect whether the endoscope is in the in-situ state has become a technical problem to be solved in the prior art. Summary of the Invention

[0006] Embodiments of the present application provide an in-situ detection mechanism for an endoscope, a system host of an endoscope system, and an endoscope system, which can automatically detect whether the endoscope is in the in-situ state.

[0007] In an embodiment of the present application, an in-situ detection mechanism for an endoscope is provided, including:

[0008] A translation member movably mounted on a lens tube socket; wherein, the lens tube socket is located in the system host of the endoscope system, and the lens tube socket is used for plugging in the lens tube connector of the endoscope; during the period when the lens tube connector is plugged into the lens tube socket, the translation member is pushed by the lens tube connector to generate a translation displacement with a preset displacement stroke; the pushing of the translation member by the lens tube connector disappears in response to the pulling out of the lens tube connector from the lens tube socket, and the translation member automatically returns to its original position in response to the disappearance of the pushing of the lens tube connector;

[0009] An induction component, the signal state of the induction signal generated by the induction component is associated with the position of the translation member; wherein, the induction signal is set to a first signal state indicating that the endoscope is in the in-situ state due to the translation displacement of the translation member, and the induction signal is set to a second signal state indicating the disappearance of the in-situ state due to the automatic return of the translation member.

[0010] In some examples, optionally, the translation member has a default position relative to the lens tube socket, the translation displacement of the translation member causes the translation member to leave the default position, and the automatic return of the translation member causes the translation member to return to the default position; the translation direction of the translation member is parallel to the plugging and unplugging direction of the lens tube connector in the lens tube socket, the translation member is at least partially located within the plugging and unplugging stroke range of the lens tube connector in the lens tube socket when in the default position, and the length of the preset displacement stroke is the stroke calibration length of the translation member located within the plugging and unplugging stroke range when in the default position.

And when the translation member is in the default position, the default built-in length of the translation member in the hollow socket cavity is the maximum segment length.

[0014] In some examples, optionally, a fixed retaining piece is fixedly installed outside the outer opening end of the cavity bottom through hole away from the hollow socket cavity.

And the driven member generates a position change relative to the sensing component by following the movement of the translation member. Wherein: when the driven member is in the first driven position by following the translational displacement of the translation member, the driven member is within the effective sensing range of the sensing component, so that the sensing signal is set to the first signal state due to the effective sensing of the sensing component on the driven member; when the driven member is in the second driven position by following the automatic return of the translation member, the sensing component is outside the effective sensing range of the sensing component, so that the sensing signal is set to the second signal state due to the sensing failure of the sensing component on the driven member.

[0068] To make the objectives, technical solutions and advantages of the present application more clear and understandable, the following provides a further detailed description of the present application with reference to the accompanying drawings and by way of examples.

[0069] Figure 1 It is a schematic diagram of an exemplary overall structure of the in-situ detection mechanism of the endoscope in the embodiment of the present application. Figure 2 It is a schematic diagram of the assembly structure of the translation member and the lens tube socket in the in-situ detection mechanism of the endoscope in the embodiment of the present application. Please refer to Figure 1 and Figure 2 In the embodiment of the present application, an in-situ detection mechanism of an endoscope is provided. The in-situ detection mechanism of the endoscope includes a translation member 91 and an induction component 93.

[0070] In the embodiment of the present application, the translation member 91 is movably installed on the lens tube socket 11. Among them, the lens tube socket 11 is located in the system host of the endoscope system, and the lens tube socket 11 is used for plugging the lens tube connector 80 of the endoscope.

[0071] Exemplarily, in the embodiment of the present application, the lens tube socket 11 may have a hollow socket cavity 110. The lens tube socket 11 further has a socket cavity wall 111 circumferentially surrounding the hollow socket cavity 110 and a socket cavity bottom 112 covering one end opening of the hollow socket cavity 110. The insertion process of the lens tube connector 80 of the endoscope into the lens tube socket 11 may include: the lens tube connector 80 enters the hollow socket cavity 110 from the open end of the hollow socket cavity 110 until it reaches the socket cavity bottom 112 of the hollow socket cavity 110; and the extraction process of the lens tube connector 80 of the endoscope from the lens tube socket 11 may include: the lens tube connector 80 gradually moves away from the socket cavity bottom 112 until it completely exits from the open end of the hollow socket cavity 110. That is, the hollow socket cavity 110 of the lens tube socket 11 is within the insertion and extraction stroke range of the lens tube connector 80 in the lens tube socket 11. The insertion and extraction direction of the lens tube connector 80 in the lens tube socket 11 may be parallel to the depth direction of the hollow socket cavity 110, and this depth direction may be perpendicular to the socket cavity bottom 112. In this case, the translation member 91 may be movably installed on the socket cavity bottom 112 of the hollow socket cavity 110 in the depth direction, and the induction component 93 is located outside the socket cavity bottom 112.

[0072] Exemplarily, in an embodiment of the present application, the mirror tube socket 11 may further have a light-transmitting opening 85, which is used for guiding light communication with the light source module of the system host to provide a conduction path for the surgical auxiliary light beam generated by the light source module to enter the mirror tube connector 80. For example, the light-transmitting opening 85 may be located at the bottom 112 of the cavity of the hollow socket cavity 110. In this case, the installation position of the translation member 91 on the bottom 112 of the cavity of the socket cavity may be any position that avoids the light-transmitting opening 85. In the illustrated expression of the embodiment of the present application, only a dotted line coil is used to exemplarily illustrate the light-transmitting opening 85, aiming to indicate that the shape and deployment position of the light-transmitting opening 85 can be set arbitrarily, that is, the embodiment of the present application does not attempt to impose unnecessary restrictions on the shape and deployment position of the light-transmitting opening 85.

[0073] Exemplarily, in an embodiment of the present application, the translation member 91 may be a rigid member, and the movement of the translation member 91 refers to the overall movement of the translation member 91, rather than the local movement caused by local deformation of the translation member 91.

[0074] Exemplarily, in an embodiment of the present application, the translation member 91 may have a shape suitable for assembling with the mirror tube socket 11. For example, if the translation member 91 can be movably installed on the bottom 112 of the cavity of the hollow socket cavity 110, then the mirror tube socket 11 has a cavity bottom through hole 113 penetrating the bottom 112 of the cavity, and the main body shape of the translation member 91 may be a rod shape adapted to the cavity bottom through hole 113, that is, the translation member 91 may include a cylindrical shaft rod 911 penetrating the cavity bottom through hole 113. In this case, the translation direction of the translation member 91 may be the axial direction of the cylindrical shaft rod 911, and the translation direction of the translation member 91 may be parallel to the insertion and extraction direction of the mirror tube connector 80 in the mirror tube socket 11, so that the displacement stroke of the translation displacement of the translation member 91 can most reflect the insertion and extraction stroke of the mirror tube connector 80 in the mirror tube socket 11. In addition, since the installation position of the translation member 91 on the bottom 112 of the cavity of the socket cavity is determined by the deployment position of the cavity bottom through hole 113 on the bottom 112 of the cavity of the socket cavity, the deployment position of the cavity bottom through hole 113 on the bottom 112 of the cavity of the socket cavity may be any position that avoids the light-transmitting opening 85.

[0075] In an embodiment of the present application, the translation member 91 may be pushed by the mirror tube connector 80 to generate a translation displacement with a preset displacement stroke during the period when the mirror tube connector 80 is inserted into the mirror tube socket 11. Moreover, in an embodiment of the present application, the pushing of the translation member 91 by the mirror tube connector 80 disappears in response to the extraction of the mirror tube connector 80 from the mirror tube socket 11, and the translation member 91 may also generate an automatic return with a preset displacement stroke in response to the disappearance of the pushing of the mirror tube connector 80.

[0076] Exemplarily, in an embodiment of the present application, the translation member 91 may have a default position relative to the lens tube socket 11. Figure 1 and Figure 2 Both show the state where the translation member 91 is in the default position. In this case, the translational displacement of the translation member 91 can cause the translation member 91 to move away from the default position, and the automatic return of the translation member 91 can cause the translation member 91 to return to the default position. Thus, the insertion and extraction state of the lens tube connector 80 in the lens tube socket 11 reflected by each translational displacement of the translation member 91 can have a consistent reference benchmark.

[0077] Exemplarily, in an embodiment of the present application, when in the default position, the translation member 91 may be at least partially within the insertion and extraction stroke range of the lens tube connector 80 in the lens tube socket 11, and the length of the preset displacement stroke is the stroke calibration length of the translation member 91 within the insertion and extraction stroke range of the lens tube connector 80 in the lens tube socket 11 when in the default position. For example, if the translation member 91 can be movably installed on the bottom 112 of the seat cavity in the depth direction of the hollow seat cavity 110, then when in the default position, the translation member 91 is at least partially within the hollow seat cavity 110, and the stroke calibration length of the translation member 91 within the insertion and extraction stroke range when in the default position can be associated with the default built-in length L0 of the translation member 91 within the hollow seat cavity 110 when in the default position.

[0078] Exemplarily, in an embodiment of the present application, the automatic return of the translation member 91 in response to the disappearance of the pushing force of the lens tube connector 80 can be achieved by the normal elastic force applied to the translation member 91.

[0079] Exemplarily, in an embodiment of the present application, if the translation member 91 can be movably installed on the bottom 112 of the seat cavity in the depth direction of the hollow seat cavity 110, and the sensing assembly 93 is located outside the bottom 112 of the seat cavity, then the translational displacement of the translation member 91 caused by being pushed by the lens tube connector 80 can cause the translation member 91 to exit through the bottom 112 of the seat cavity to the outside of the hollow seat cavity 110.

[0080] In an embodiment of the present application, the sensing assembly 93 can be used to generate a sensing signal, and the signal state of the sensing signal generated by the sensing assembly 93 is associated with the position of the translation member 91. Specifically:

[0081] The sensing signal generated by the sensing assembly 93 can be set to a first signal state indicating that the endoscope is in the in-position state due to the translational displacement of the translation member 91. That is, the translational displacement of the translation member 91 caused by being pushed by the lens tube connector 80 to generate a preset displacement stroke can cause the sensing signal generated by the sensing assembly 93 to be set to the first signal state indicating that the endoscope is in the in-position state;

[0082] The induction signal generated by the induction component 93 can be set to a second signal state indicating the disappearance of the in-position state of the endoscope due to the automatic return of the translation member 91. That is, the automatic return of the translation member 91 in response to the disappearance of the pushing force on the mirror tube connector 80 can cause the induction signal generated by the induction component 93 to be set to the second signal state indicating the disappearance of the in-position state of the endoscope.

[0083] That is, in the embodiment of the present application, the state switching sensitivity of the induction signal generated by the induction component 93 between the first signal state and the second signal state can be determined by the translation displacement generated by the translation member 91 and the length of the preset displacement stroke of the automatic return. Moreover, the length of the preset displacement stroke can be associated with the default built-in length L0 of the translation member 91 in the hollow seat cavity 110 when in the default position. Therefore, as long as the default built-in length L0 of the translation member 91 in the hollow seat cavity 110 when in the default position is reasonably set, the state switching sensitivity of the induction signal can be set within a preferred range to meet the requirement for the timeliness of detecting the in-position state of the endoscope, and at the same time, to avoid the signal state of the induction signal from being erroneously switched when affected by the external environment (such as the system host being vibrated, etc.) due to too high state switching sensitivity.

[0084] Exemplarily, in the embodiment of the present application, the induction component 93 can be deployed inside the system host of the endoscope system, and the induction component 93 can be electrically connected to the main control module and / or the light source module in the system host. That is, the induction signal generated by the induction component 93 can be sent to the main control module for the main control module to implement the enabling control of the light source module based on the induction signal, or the induction signal generated by the induction component 93 can also directly act on the enabling control terminal of the light source module. For example, in the illustrated expression of the present application, the induction component 93 can include a circuit board 930, and the circuit board 930 can be provided with a component mounting rack 931 and a signal transmission interface 932 for outputting the induction signal to the main control module and / or the light source module. Moreover, the component mounting rack 931 can be provided with induction elements.

[0085] Exemplarily, in the embodiments of the present application, the sensing assembly 93 may include a non-contact sensing element. For example, the non-contact sensing element includes at least one of a photoelectric sensing element, an inductive sensing element, a capacitive sensing element, and a magnetic sensing element; alternatively, the sensing assembly 93 may include a contact sensing element. For example, the contact sensing element includes at least one of a metal contact and a switching element. For example, in the illustrated expression of the embodiments of the present application, the component mounting bracket 931 of the circuit board 930 may have a pair of mounting plates arranged at intervals, and the sensing assembly 93 may include a photoelectric sensing element (i.e., at least a pair of phototransmitters and photoreceivers). The phototransmitter and the photoreceiver may be arranged in pairs and aligned on the pair of mounting plates of the component mounting bracket 931, so as to form a non-contact sensing space between the pair of mounting plates of the component mounting bracket 931.

[0086] Exemplarily, in the embodiments of the present application, in order to enable the signal state of the sensing signal to change in association with the position change of the translation member 91, the sensing assembly 93 may use the translation member 91 as the sensing object, or the sensing assembly 93 may not directly sense the translation member 91, but use other members that can be linked with the translation member 91 as alternative sensing objects. As described above, the sensing assembly 93 may be deployed inside the system host of the endoscope system. Therefore, if the translation member 91 is used as the sensing object of the sensing assembly 93, the deployment position of the sensing assembly 93 will be limited to the translation path of the translation member 91, which is not conducive to the flexible deployment of the sensing assembly 93 inside the system host, and further affects the deployment positions of other components inside the system host. Based on the above considerations, the embodiments of the present application preferably use other members that can be linked with the translation member 91 as the sensing objects of the sensing assembly 93 to allow the position of the sensing assembly 93 inside the system host to be deployed arbitrarily.

[0087] In the embodiments of the present application, in order to support the flexible deployment of the position of the sensing assembly 93, as Figure 1 and Figure 2 shown, the endoscope in-position detection mechanism in the embodiments of the present application may further include a driven member 92, and the sensing assembly 93 may use the driven member 92 as the sensing object.

[0088] Exemplarily, in the embodiments of the present application, the driven member 92 is located outside the bottom 112 of the seat cavity, and the sensing assembly 93 may be deployed in any orientation outside the bottom 112 of the seat cavity. The driven member 92 may include a rod-shaped main body 920. The rod-shaped main body 920 may extend from the translation path of the translation member 91 towards the orientation where the sensing assembly 93 is located, and the extending end of the rod-shaped main body 920 may have an execution end 922 for being sensed by the sensing assembly 93.

[0089] In an embodiment of the present application, the driven member 92 generates a position change relative to the sensing assembly 93 by following the movement of the translation member 91. In this case,

[0090] When the driven member 92 is in the first driven position following the translational displacement of the translation member 91, the driven member 92 is within the effective sensing range of the sensing assembly 93, causing the sensing signal to be set to the first signal state due to the effective sensing of the driven member 92 by the sensing assembly 93;

[0091] When the driven member 92 is in the second driven position following the automatic return of the translation member 91, the sensing assembly 93 is outside the effective sensing range of the sensing assembly 93, causing the sensing signal to be set to the second signal state due to the sensing failure of the driven member 92 by the sensing assembly 93.

[0092] For example, if the sensing assembly 93 forms a non-contact sensing space between a pair of mounting plates of the element mounting bracket 931 described above using a photoelectric sensing element, then:

[0093] The first driven position of the driven member 92 can be within the sensing space between a pair of mounting plates of the element mounting bracket 931, so as to cause the sensing signal generated by the sensing assembly 93 to be set to the first signal state indicating that the endoscope is in place;

[0094] The second driven position of the driven member 92 can be outside the sensing space between a pair of mounting plates of the element mounting bracket 931, so as to cause the sensing signal generated by the sensing assembly 93 to be set to the second signal state indicating the disappearance of the in-place state of the endoscope.

[0095] For another example, if the sensing assembly 93 includes a contact sensing element, then, when the driven member 92 is in the first driven position, it can be in physical contact with the contact sensing element of the sensing assembly 93, and when the driven member 92 is in the second driven position, it can be physically separated from the contact sensing element of the sensing assembly 93.

[0096] In an embodiment of the present application, regardless of whether the sensing assembly 93 includes a non-contact sensing element or a contact sensing element, and regardless of the orientation of the sensing assembly 93 relative to the translation path of the translation member 91, due to the position switching stroke of the driven member 92 between the first driven position and the second driven position being associated with the preset displacement strokes of the translational displacement and automatic return of the translation member 91, therefore, when introducing the driven member 92 to replace the translation member 91 as the sensing object of the sensing assembly 93, it is still possible to reasonably configure the state switching sensitivity of the sensing signal generated by the sensing assembly 93 between the first signal state and the second signal state by setting the default built-in length L0 of the translation member 91 in the hollow seat cavity 110 when it is in the default position.

[0097] As can be seen above, based on the above embodiments of the present application, a translation member 91 can be installed on the lens tube socket 11 of the system host of the endoscope system, and an induction component 93 for generating an induction signal according to the position of the translation member 91 is provided. Among them, the translation member 91 can generate a translation displacement with a preset displacement stroke during the period when the lens tube connector 80 of the endoscope is inserted into the lens tube socket 11, and the translation member 91 can also automatically return to its original position in response to the pulling out of the lens tube connector 80 from the lens tube socket 91. Thus, the signal state of the induction signal generated by the induction component 93 can change dynamically following the translation displacement and automatic return of the translation member 91, so as to characterize whether the endoscope is in the in-position state where the lens tube connector 80 is inserted into the lens tube socket 11, and further realize the automatic detection of whether the endoscope is in position.

[0098] Figure 3 It is a schematic diagram of the anti-rotation constraint structure between the translation member and the lens tube socket in the endoscope in-position detection mechanism in the embodiments of the present application. Please refer to Figure 2 while further combining with Figure 3 In the embodiments of the present application, in addition to having a columnar shaft rod 911, the translation member 91 may further have an annular flange 912 surrounding the outer periphery of the columnar shaft rod 911, and when the columnar shaft rod 911 passes through the cavity bottom through hole 113, the annular flange 912 is slidably located in the cavity bottom through hole 113.

[0099] In the embodiments of the present application, the first end section 911a of the columnar shaft rod 911 is located on the side of the annular flange 912 close to the hollow seat cavity 110. The inner opening end of the cavity bottom through hole 113 of the lens tube socket 11 close to the hollow seat cavity 110 has a limit flange 114, and the maximum section length of the first end section 911a of the columnar shaft rod 911 extending into the hollow seat cavity 110 is restricted by the limit and block of the limit flange 114 on the annular flange 912. In this case, the default built-in length L0 of the translation member 91 in the hollow seat cavity 110 when in the default position is: the maximum section length of the first end section 911a of the columnar shaft rod 911 extending into the hollow seat cavity 110.

[0100] In the embodiments of the present application, a fixed retaining piece 115 is fixedly installed (for example, fixed by screws) outside the outer opening end of the cavity bottom through hole 113 of the lens tube socket 11 far from the hollow seat cavity 110. The columnar shaft rod 911 penetrates the fixed retaining piece 115, and an elastic element 116 (such as a spring sleeved on the outer periphery of the columnar shaft rod 911) is arranged between the annular flange 912 and the fixed retaining piece 115, and the elastic element 116 generates an elastic restoring force for the automatic return of the translation member 91 on the annular flange 912.

[0101] In the embodiments of the present application, please pay special attention to Figure 3, the hole wall of the cavity bottom through hole 113 of the mirror tube socket 11 has a guiding chute 117 extending in the axial direction parallel to the cavity bottom through hole 113. The translation member 91 further has a flange lug 913 protruding from the outer edge of the annular flange 912. The flange lug 913 is slidably embedded in the guiding chute 117, and a rotation prevention constraint that prevents the translation member 91 from rotating relative to the cavity bottom through hole 113 is formed between the flange lug 913 and the guiding chute 117, that is, the degrees of freedom of movement of the translation member 91 can only include translation.

[0102] In an embodiment of the present application, the columnar shaft rod 911 of the translation member 91 further has a second end segment 911b suspended outside the cavity bottom 112 of the seat cavity, and the second end segment 911b is physically matched with the driven member 92.

[0103] For example, the physical matching between the second end segment 911b of the columnar shaft rod 911 of the translation member 91 and the driven member 92 may include: the driven member 92 is fixedly connected to the second end segment 911b of the columnar shaft rod 911 of the translation member 91. In this case, the moving direction of the driven member 92 following the translation member 91 is the same as the translation direction of the translation member 91.

[0104] Or, the physical matching between the second end segment 911b of the columnar shaft rod 911 of the translation member 91 and the driven member 92 may include: the driven member 92 is in transmission cooperation with the second end segment 911b of the columnar shaft rod 911 of the translation member 91. In this case, the moving direction of the driven member 92 following the translation member 91 may intersect with the translation direction of the translation member 91.

[0105] Figure 4 It is a schematic diagram of the first example of the physical matching structure between the translation member and the driven member in the in-situ detection mechanism of the endoscope in the embodiment of the present application. Please refer to Figure 4 , in an embodiment of the present application, if the driven member 92 is fixedly connected to the second end segment 911b of the columnar shaft rod 911 of the translation member 91, then the driven member 92 may have an assembly base 921. For example, the assembly base 921 may be located at one end of the rod-shaped main body 920 close to the translation member 91, that is, the assembly base 921 and the execution end 922 may be located at opposite ends of the rod-shaped main body 920 respectively.

[0106] In an embodiment of the present application, the assembly base 921 of the driven member 92 has an insertion groove 921a, which has a groove bottom 921b. The second end segment 911b of the columnar shaft 911 of the translation member 91 is inserted into the insertion groove 921a, and the end face of the second end segment 911b contacts the groove bottom 921b of the insertion groove 921a. An installation through hole 921c may be provided in the groove bottom 921b, and an axial screw hole 911c may be provided in the end face of the second end segment 911b. Thus, the axial screw passing through the installation through hole 921c can be screwed into the axial screw hole 911c to realize the fixed connection of the second end segment 911b of the columnar shaft 911 of the translation member 91 in the axial direction with the driven member 92 (i.e., the assembly base 921).

[0107] In an embodiment of the present application, the insertion groove 921a of the assembly base 921 of the driven member 92 further has a limiting groove wall 921d. The second end segment 911b of the columnar shaft 911 of the translation member 91 has an end key surface 911d that is in limiting cooperation with the limiting groove wall 921d. Moreover, the limiting cooperation between the end key surface 911d of the second end segment 911b and the limiting groove wall 921d of the insertion groove 921a can form a rotation-preventing constraint that prevents the driven member 92 from rotating relative to the translation member 91.

[0108] Figure 5 It is a schematic diagram of the second example of the physical cooperation structure between the translation member and the driven member in the in-situ detection mechanism of the endoscope in the embodiment of the present application. Please refer to Figure 5 , in an embodiment of the present application, if the driven member 92 is in transmission cooperation with the second end segment 911b of the columnar shaft 911 of the translation member 91, then the transmission cooperation between the driven member 92 and the second end segment 911b can adopt a wedge surface sliding cooperation. Specifically:

[0109] The second end segment 911b of the columnar shaft 911 of the translation member 91 may have a force-applying wedge surface 911e. For example, the end face of the second end segment 911b may be machined into a force-applying wedge surface 911e;

[0110] The driven member 92 has a force-receiving wedge surface 921e. The force-receiving wedge surface 921e may be located at one end of the rod-shaped main body 920 close to the translation member 91, that is, the force-receiving wedge surface 921e and the execution end 922 may be located at opposite ends of the rod-shaped main body 920 respectively;

[0111] The driven member 92 and the second end portion segment 911b can achieve the wedge surface sliding fit between the driven member 92 and the second end portion segment 911b through the sliding fit of the force-receiving wedge surface 921e and the force-applying wedge surface 911e. Moreover, the force-receiving wedge surface 921e of the driven member 92 can be constrained (for example, constrained by the elastic holding force generated by a spring on the driven member 92) to maintain physical contact with the force-applying wedge surface 911e of the second end portion segment 911b.

[0112] In another embodiment of the present application, a system host of an endoscope system is further provided. The system host may include the endoscope in-position detection mechanism described above, a lens tube socket 11, and a light source module, wherein:

[0113] The light source module is used to generate a surgical auxiliary light beam during startup operation, and the surgical auxiliary light beam is used to conduct forward through the lens tube connector 80 inserted into the lens tube socket 11 to the front end of the lens tube of the endoscope;

[0114] The lens tube socket 11 has a light-transmitting opening 85. The light-transmitting opening 85 is in light-conducting communication with the light source module, and the light-transmitting opening 85 provides a conduction path for the surgical auxiliary light beam to enter the lens tube connector 80;

[0115] The induction signal generated by the induction component 93 is used to enable control of the light source module, so as to limit the startup operation of the light source module during the period when the lens tube connector 80 is in the in-position state.

[0116] For example, the induction component 93 can be electrically connected to the main control module and / or the light source module in the system host. That is, the induction signal generated by the induction component 93 can be sent to the main control module for the main control module to perform enable control on the light source module based on the induction signal. Or, the induction signal generated by the induction component 93 can also directly act on the enable control terminal of the light source module.

[0117] Thus, when the endoscope in-position detection mechanism in the foregoing embodiment is applied to the system host of the endoscope system, the endoscope host can have the ability to automatically detect whether the endoscope is in the in-position state (that is, whether the lens tube connector 80 is inserted into the lens tube socket 11). Therefore, it helps to avoid the situation that the light source module is started when the endoscope is not in the in-position state (that is, the lens tube connector 80 is not inserted into the lens tube socket 11). Furthermore, it helps to avoid the surgical auxiliary light beam directly shooting out from the light-transmitting opening of the lens tube socket 11 to the scene environment where the system host is located, that is, it can avoid light pollution to the scene environment where the system host is located, and it also helps to avoid the surgical auxiliary light beam shooting out from the lens tube socket 11 from causing harm to the personnel in the scene environment.

[0118] In another embodiment of the present application, an endoscope system is further provided. The endoscope system includes the above-mentioned system host and an endoscope having a lens tube connector 80.

[0119] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
