Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an image transmission fiber self-adaptive structure and an endoscope image transmission system. BACKGROUND

[0002] The image transmission fiber self-adaptive structure is a very important component in the endoscope system. The image transmission fiber self-adaptive structure connects the main machine end image transmission fiber ferrule of the endoscope main machine and the scope end image transmission fiber ferrule of the endoscope scope to transmit optical signals, so as to transmit the image data collected by the scope end to the main machine end in the form of optical signals. In order to realize high-quality transmission of image data, the collimation of the scope end image transmission fiber ferrule and the main machine end image transmission fiber ferrule is required to be very high.

[0003] The existing image transmission fiber self-adaptive structure is provided with a docking structure and a spring matched with the docking structure. The main machine end image transmission fiber ferrule and the scope end image transmission fiber ferrule are docked in the docking space formed by the docking structure, and then the spring is used to make the main machine end image transmission fiber ferrule adapt to the insertion direction of the scope end image transmission fiber ferrule, so as to achieve the alignment effect. However, when the main machine end image transmission fiber ferrule and the scope end image transmission fiber ferrule are docked by using the existing image transmission fiber self-adaptive structure, the docking is often inaccurate, which leads to low transmission optical power value, and further leads to poor image quality of the optical signal transmission, and even the problem of no image formation. CONTENT OF THE UTILITY MODEL

[0006] The image transmission fiber self-adaptive structure of the utility model, when the second fiber ferrule is aligned with the first fiber ferrule in the butt joint space along the first direction, the elastic member provides self-adaptive compensation (i.e. elastic force) to maintain the stability and accuracy of butt joint; if the actual insertion direction of the second fiber ferrule deviates from the first direction or there is an assembly error, the limiting member can limit the second fiber ferrule from moving along the first direction, thereby avoiding the phenomenon that the friction between the second fiber ferrule and the butt joint structure is greater than the elastic force of the elastic member due to the insertion angle deviation or assembly error, and further causing the butt joint structure to move along the first direction, resulting in inaccurate butt joint or even unable to butt joint between the second fiber ferrule and the first fiber ferrule. In this way, even if there is an insertion angle deviation or assembly error, through the synergistic effect of the limiting member and the elastic member, the second fiber ferrule can still realize precise butt joint with the first fiber ferrule in the butt joint space along the first direction, ensuring the elastic force of the elastic member, and further realizing high-quality transmission of image data with stable optical power.

DETAILED DESCRIPTION

[0028] In the following description, a large number of details are provided in order to allow a thorough understanding of the present application. However, it can be appreciated by those skilled in the art that the following description only exemplarily shows the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0029] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can also have other embodiments.

[0030] The embodiment of the utility model provides a kind of image transmission optical fiber self-adapting structure.The utility model discloses an image transmission optical fiber self-adapting structure can be applied in endoscope image transmission system.The image transmission optical fiber self-adapting structure according to the utility model embodiment will be described in detail in combination with drawings.

[0031] In combination with referring to Figures 1 to 5 The image transmission optical fiber self-adapting structure 10 can include a fixed seat 110, a docking structure 120, and a limiting piece 130. The docking structure 120 can be connected to the fixed seat 110 through an elastic piece 140, and the docking structure 120 can have a docking space 1201 for docking a first optical fiber ferrule 150 and a second optical fiber ferrule 160. The first optical fiber ferrule 150 can be placed in the docking space 1201, and the second optical fiber ferrule 160 can be configured to be at least partially inserted into the docking space 1201 along a first direction X to be in abutment with the first optical fiber ferrule 150. The first optical fiber ferrule 150 can be connected to a host computer (not shown in the figure). The second optical fiber ferrule 160 can be connected to an endoscope lens (not shown in the figure). The second optical fiber ferrule 160 can transmit image data collected by the endoscope lens in the form of optical signals. The first optical fiber ferrule 150 can receive the optical signals transmitted by the second optical fiber ferrule 160 and transmit the received optical signals to the host computer. The docking structure 120 can also have a limiting cooperation wall 1202. The limiting piece 130 can abut against the limiting cooperation wall 1202 to limit the movement of the docking structure 120 along the first direction X. The first direction X can be the direction in which the second optical fiber ferrule 160 approaches the first optical fiber ferrule 150.

[0032] The image transmission optical fiber self-adapting structure 10 of the utility model, when the second optical fiber ferrule 160 is aligned with the first optical fiber ferrule 150 in the docking space 1201 along the first direction X, the elastic piece 140 provides adaptive compensation (i.e., elastic force) to maintain the stability and accuracy of the docking. If the actual insertion direction of the second optical fiber ferrule 160 deviates from the first direction X or there is an assembly error, the limiting piece 130 can limit the movement of the docking structure 120 along the first direction X driven by the second optical fiber ferrule 160, thereby avoiding the phenomenon that the friction between the second optical fiber ferrule 160 and the docking structure 120 is greater than the elastic force of the elastic piece 140 due to the deviation of the insertion angle or the assembly error, which in turn causes the docking structure 120 to move along the first direction X, resulting in inaccurate or even impossible docking between the second optical fiber ferrule 160 and the first optical fiber ferrule 150. In this way, even if there is a deviation in the insertion angle or an assembly error, through the synergistic effect of the limiting piece 130 and the elastic piece 140, the second optical fiber ferrule 160 can still achieve precise docking with the first optical fiber ferrule 150 in the docking space 1201 along the first direction X, ensuring the adaptive elastic force of the elastic piece 140, which in turn can maintain stable optical power to achieve high-quality transmission of image data.

[0033] In combination with referring toFigures 2 to 4 The docking structure 120 can include a fixing member 121 and a locking member 122. The elastic member 140 can be connected between the fixing member 121 and the fixing seat 110. The docking space 1201 can be formed in the fixing member 121. The first fiber ferrule 150 can be fixed in the docking space 1201 by the locking member 122. In this way, the displacement of the first fiber ferrule 150 in the docking space 1201 can be prevented, so as to realize the precise docking of the second fiber ferrule 160 and the first fiber ferrule 150.

[0034] Specifically, the outer surface of the locking member 122 can be provided with external threads, and the inner surface of the fixing member 121 can be provided with internal threads. The locking member 122 can be locked in the fixing member 121 by thread connection. The locking member 122 can have a first accommodating cavity 1221. A part of the first fiber ferrule 150 can be placed in the first accommodating cavity 1221. The fixing seat 110 can have a second accommodating cavity 111. The fiber connected with the first fiber ferrule 150 can be sequentially arranged in the first accommodating cavity 1221 and the second accommodating cavity 111. The elastic member 140 can be a spring. The spring is sleeved on one end of the fixing seat 110 and one end of the fixing member 121 respectively. The elastic force of the spring can be applied to the fixing member 121. For example, when the second fiber ferrule 160 is docked with the first fiber ferrule 150 in the docking space 1201, a certain deformation is generated by the spring. The fixing member 121 and the first fiber ferrule 150 are adaptively aligned with the second fiber ferrule 160.

[0035] Referring to Figure 4The docking space 1201 can include a first chamber 1201a and a second chamber 1201b. The first chamber 1201a can be in communication with the second chamber 1201b. A portion of the first fiber ferrule 150 can be disposed in the first chamber 1201a, and another portion of the first fiber ferrule 150 can be disposed in the second chamber 1201b. When the second fiber ferrule 160 is docked with the first fiber ferrule 150, at least a portion of the second fiber ferrule 160 can be disposed in the second chamber 1201b. Understandably, the portion of the first fiber ferrule 150 used for docking with the second fiber ferrule 160 is disposed in the second chamber 1201b. A portion of the locking member 122 can be disposed in the first chamber 1201a, and another portion of the locking member 122 can be disposed at the end of the fixing member 121 away from the second fiber ferrule 160. The fixing member 121 can have a first inner wall surface 1211 configured as an inner wall surface of the first chamber 1201a and a second inner wall surface 1212 configured as an inner wall surface of the second chamber 1201b. In the radial direction, the first inner wall surface 1211 can be farther away from the first fiber ferrule 150 than the second inner wall surface 1212, and the first inner wall surface 1211 and the second inner wall surface 1212 can be connected by a step surface 1213. At least a portion of the first fiber ferrule 150 disposed in the first chamber 1201a protrudes towards the first inner wall surface 1211 to form a fixing portion 151. The fixing portion 151 is fixed by the step surface 1213 and the locking member 122 to fix the first fiber ferrule 150 in the docking space 1201. Specifically, one end of the fixing portion 151 abuts against the step surface 1213, and the other end of the fixing portion 151 abuts against one end surface of the locking member 122. In this way, a portion of the first fiber ferrule 150 is fixed in the first chamber 1201a, and another portion of the first fiber ferrule 150 (i.e., the portion used for docking with the second fiber ferrule 160) is disposed in the second chamber 1201b. In this way, the first fiber ferrule 150 is fixed in the first chamber 1201a, which enhances the stability of the connection between the first fiber ferrule 150 and the fixing member 121 and avoids the phenomenon of the first fiber ferrule 150 shaking when the second fiber ferrule 160 is inserted into the second chamber 1201b to dock with the first fiber ferrule 150, thereby enhancing the accuracy of docking between the first fiber ferrule 150 and the second fiber ferrule 160. The guidance of the second fiber ferrule 160 in the first direction X by the second chamber 1201b further enhances the accuracy of docking between the first fiber ferrule 150 and the second fiber ferrule 160.

[0036] Again refer to Figure 4The fixing member 121 can include a seat body 1214 and a ceramic sleeve 1215. The first cavity 1201a can be enclosed by the seat body 1214. The ceramic sleeve 1215 can be fixedly arranged in the seat body 1214. The second cavity 1201b can be enclosed by the ceramic sleeve 1215. When the second fiber ferrule 160 is butted against the first fiber ferrule 150, the second fiber ferrule 160 can be inserted into the second cavity 1201b from the end of the ceramic sleeve 1215 away from the first cavity 1201a. Through the positioning and guiding effect of the ceramic sleeve 1215 on the first fiber ferrule 150 and the second fiber ferrule 160, the precision of the butt joint of the first fiber ferrule 150 and the second fiber ferrule 160 is enhanced.

[0037] With reference to Figure 3 and Figure 4 The outer surface of the butt joint structure 120 can be recessed into the butt joint space 1201 to form a limiting groove 1214a. Specifically, the limiting groove 1214a can be recessed into the outer surface of the seat body 1214 towards the first cavity 1201a. The limiting groove 1214a can include a bottom wall 1214b and first side walls 1214c connected to both sides of the bottom wall 1214b, wherein the first side wall 1214c near the second fiber ferrule 160 can form a limiting fitting wall 1202. In this way, by forming the limiting fitting wall 1202 on the first side wall 1214c of the limiting groove 1214a near the second fiber ferrule 160, the limiting fitting wall 1202 abuts against the limiting member 130 to block the movement of the seat body 1214 in the first direction X.

[0038] With reference to Figures 1 to 7 The limiting member 130 can be configured as a semi-enclosing body 131 with a gap. The semi-enclosing body 131 can be enclosed by the gap in the bottom wall 1214b. The semi-enclosing body 131 can have two opposite side surfaces 132, one of which can abut against the limiting fitting wall 1202, and the semi-enclosing body 131 can form a fitting wall 133 at the edge of the gap, and the fitting wall 133 can have a gap 170 with the bottom wall 1214b. The side surface 132 of the semi-enclosing body 131 abutting against the limiting fitting wall 1202 can be the side near the second fiber ferrule 160. By abutting the side surface 132 of the semi-enclosing body 131 against the limiting fitting wall 1202, the movement of the seat body 1214 in the first direction X is effectively blocked. Specifically, the semi-enclosing body 131 forms two limiting portions 134 abutting against the limiting fitting wall 1202 through the gap. Since the limiting fitting wall 1202 can be an annular wall, by providing two limiting portions 134, it is convenient to abut, thereby blocking the movement of the seat body 1214 in the first direction X. In addition, the fitting wall 133 has a gap 170 with the bottom wall 1214b, so as not to affect the adaptive elastic force of the elastic member 140. Of course, it is not excluded that the fitting wall 133 can abut against the bottom wall 1214b.

[0039] In an embodiment not shown, the outer surface of the docking structure 120 can be convexed with an annular boss in a direction away from the docking space 1201. Specifically, the annular boss can be formed on the outer surface of the seat body 1214 in a direction away from the ceramic sleeve 1215. The annular boss can have two opposite walls oppositely arranged, wherein the opposite wall away from the second fiber ferrule 160 can be configured as the limiting fitting wall 1202. In this way, by configuring the opposite wall of the boss away from the second fiber ferrule 160 as the limiting fitting wall 1202, the limiting fitting wall 1202 abuts against the limiting piece 130 to block the seat body 1214 from moving in the first direction X.

[0040] The limiting piece 130 can be configured as a semi-enclosing body 131 with a notch. The semi-enclosing body 131 can be enclosed around the outer surface of the docking structure 120 (i.e. the outer surface of the seat body 1214) through the notch. The semi-enclosing body 131 can have two opposite side surfaces 132, wherein one side surface 132 can abut against the limiting fitting wall 1202, and the semi-enclosing body 131 can form a fitting wall 133 at the edge of the notch, and the fitting wall 133 can have a gap 170 with the outer surface of the docking structure 120. Since the limiting piece 130 has the same beneficial effects and specific technical features as the above-mentioned limiting piece 130, they will not be repeated here. In addition, the fitting wall 133 has the gap 170 with the outer surface of the docking structure 120, so as not to affect the adaptive elastic force of the elastic piece 140. Of course, it is not excluded that the fitting wall 133 can abut against the outer surface of the docking structure 120.

[0041] Again referring to Figure 4 , the seat body 1214 can be provided with an extension 1214d extending towards the ceramic sleeve 1215 at the end away from the first cavity 1201a. The extension length of the extension 1214d can be the same as the thickness of the ceramic sleeve 1215, and a chamfer 1214e can be provided on the edge away from the ceramic sleeve 1215. In this way, by fixing the ceramic sleeve 1215 through the extension 1214d and the fixing part 151, the movement of the ceramic sleeve 1215 when the first fiber ferrule 150 and the second fiber ferrule 160 are docked or undocked is avoided, thereby improving the fitting degree. By providing the chamfer 1214e on the extension 1214d away from the edge of the ceramic sleeve 1215, it is convenient for the second fiber ferrule 160 to be inserted into the second cavity 1201b, and the collision between the second fiber ferrule 160 and the edge of the extension 1214d is avoided to cause damage to the second fiber ferrule 160.

[0042] In combination with referring to Figures 1 to 5, specifically describes the butting process of the second optical fiber ferrule 160 and the first optical fiber ferrule 150, the first optical fiber ferrule 150 is limited by the locking piece 122 and the step face 1213, a part of the first optical fiber ferrule 150 is fixed in the first cavity 1201a, another part of the first optical fiber ferrule 150 is fixed in the second cavity 1201b, the second optical fiber ferrule 160 is inserted into the second cavity 1201b from one end of the ceramic sleeve 1215 close to the extension 1214d along the first direction X, the second optical fiber ferrule 160 moves in the second cavity 1201b and generates a friction force with the inner wall of the ceramic sleeve 1215, the elastic piece 140 provides adaptive compensation (the elastic piece 140 elastically deforms to generate an elastic force to offset the friction force) to maintain the stability and accuracy of the butt joint of the first optical fiber ferrule 150 and the second optical fiber ferrule 160; when the second optical fiber ferrule 160 is manually inserted into the second cavity 1201b, the actual insertion direction of the second optical fiber ferrule 160 is easy to deviate from the first direction X, or due to the deviation of the processing of the ceramic sleeve 1215 or other matching parts of the first optical fiber ferrule 150, the friction force generated by the movement of the second optical fiber ferrule 160 in the second cavity 1201b and the inner wall of the ceramic sleeve 1215 is greater than the elastic force of the elastic piece 140, the second optical fiber ferrule 160 exerts a force on the fixing piece 121 and the elastic piece 140 towards the first direction X, the limiting piece 130 abuts to the limiting piece 130 through the limiting cooperation wall 1202, the limiting piece 130 blocks the movement of the fixing piece 121 towards the first direction X, at the same time, the elastic piece 140 keeps exerting an elastic force on the fixing piece 121, the elastic piece 140 can deform during the butt joint process of the second optical fiber ferrule 160 and the first optical fiber ferrule 150, and can offset the greater friction force generated between the second optical fiber ferrule 160 and the ceramic sleeve 1215 due to the insertion angle deviation or assembly error under the synergistic action of the limiting piece 130 and the elastic piece 140, so that the second optical fiber ferrule 160 and the first optical fiber ferrule 150 can be adaptively aligned, and accurate butt joint of the second optical fiber ferrule 160 and the first optical fiber ferrule 150 is achieved.

[0043] According to an aspect of the present application, an endoscope image transmission system is provided. Referring to Figure 1 The endoscope image transmission system can include a host, an endoscope lens, a connecting ring 20, and an image transmission fiber adaptive structure 10 as described above. The host can be connected with the first optical fiber ferrule 150 through an optical fiber. The endoscope lens can be connected with the second optical fiber ferrule 160 through an optical fiber. The fixing seat 110 and the limiting piece 130 can be fixed on the connecting ring 20. Since the image transmission fiber adaptive structure 10 has the above beneficial effects, the endoscope image transmission system including the image transmission fiber adaptive structure 10 also has the above beneficial effects, which will not be repeated here.

[0044] Specifically,Figures 1 to 7 The fixing seat 110 and the connecting ring 20 can be locked by threaded connection, for example, the outer surface of the fixing seat 110 is provided with external threads, and the connecting ring 20 is provided with a mounting hole, and the inner surface of the mounting hole is provided with internal threads. The limiting member 130 can further include a fixing body 135 extending out of the semi-enclosing body 131 in the first direction X, and the fixing body 135 can be connected with the connecting ring 20 by a screw.
