[0025] The elastic connecting piece and endoscope provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings 1 to 8 through specific embodiments and application scenarios.

[0026] The elastic connecting piece of the embodiment is used on an endoscope and can be used as a connecting piece between the insertion part 20 and the cable 30 and the handle 10, as shown in FIGS. 1 and 2. The endoscope of the embodiment can be a disposable endoscope, a limited-time reusable endoscope, or an unlimited-time reusable endoscope. The endoscope of the embodiment can be a bronchoscope, a nephroscope, an esophagoscope, a gastroscope, a colonoscope, an otoscope, a nasoscope, an oral cavity scope, a laryngoscope, a colposcope, a laparoscope, an arthroscope, or the like. The embodiment does not specifically limit the type of endoscope.

[0027] The elastic connecting piece of the embodiment includes an elastic body 110, as shown in FIGS. 3-5. The elastic body 110 is made of a material with elasticity, such as silicone, rubber, or the like. The elastic body 110 can be used as a mounting base of the insertion part 20 and the cable 30.

[0028] In some embodiments, the elastic body 110 is sealingly connected to the shell 11 of the handle 10 of the endoscope. For example, the elastic body 110 can be arranged at the distal end of the handle 10. The elastic body 110 can be used as a mounting base of the insertion part 20 and the cable 30 and can also seal the distal end of the handle 10, as shown in FIGS. 1 and 2. For example, the elastic body 110 is made of a material with elasticity, so that the elastic body 110 and the shell 11 can be sealingly connected through interference fit.

[0029] In some embodiments, the elastic body 110 is provided with a first channel 111, as shown in FIGS. 3 and 5. The first channel 111 penetrates the elastic body 110 and is used to mount the insertion part 20 of the endoscope, as shown in FIGS. 1-3 and 5. After the insertion part 20 is mounted in the first channel 111, the proximal end of the insertion part 20 can be connected to the inner cavity of the handle 10, so that instrument operation, negative pressure suction, or the like can be performed.

[0030] In some embodiments, the first channel 111 is sealingly connected to the insertion part 20. For example, the first channel 111 and the insertion part 20 can be sealingly connected through interference fit. Alternatively, a sealing ring can be arranged between the first channel 111 and the insertion part 20 to achieve sealing connection.

[0031] In some embodiments, the elastic body 110 is provided with a second channel 112, as shown in FIGS. 3 and 5. The second channel 112 penetrates the elastic body 110 and is used to mount the cable 30 of the endoscope, as shown in FIGS. 1-3 and 5. After the cable 30 is mounted in the second channel 112, the proximal end of the cable 30 can be connected to the inner cavity of the handle 10, so that the cable 30 can be connected to a chip in the inner cavity, and images collected by the insertion part 20 can be displayed on a display device.

[0032] In some embodiments, the second channel 112 is sealingly connected with the cable 30. For example, the second channel 112 and the cable 30 can be sealingly connected by interference fit. Alternatively, a sealing ring can be arranged between the second channel 112 and the cable 30 to sealingly connect the second channel 112 and the cable 30.

[0033] Compared with the prior art in which the insertion portion 20 and the cable 30 are directly connected with the relatively hard shell 11, in the present embodiment, the insertion portion 20 and the cable 30 are mounted on the elastic body 110 having elasticity. When the insertion portion 20 is bent, part of the energy can be absorbed by the deformation of the elastic body 110, so that the influence of the bending of the insertion portion 20 on the sealing performance of the connection between the elastic body 110 and the insertion portion 20 can be reduced. Similarly, the elastic body 110 can also reduce the influence of the pulling action of the cable 30 on the sealing performance of the connection between the elastic body 110 and the cable 30. The use of the elastic connector of the present embodiment in an endoscope can improve the sealing performance of the endoscope.

[0034] That is, the elastic connector of the present embodiment can solve the technical problem that the sealing performance of the shell 11 of the handle 10 in the related art is easily affected by the pulling action of the insertion portion 20 and the cable 30.

[0035] In some embodiments, the first channel 111 is provided with a first sleeve portion 1111 at the distal end, and the first sleeve portion 1111 is in communication with the first channel 111, as shown in FIGS. 3-5. For example, the first sleeve portion 1111 can be formed by extending the first channel 111 distally. Alternatively, the first sleeve portion 1111 can be a structure integrated on the elastic body 110. The first sleeve portion 1111 and the first channel 111 are integrally formed.

[0036] In the present embodiment, the first sleeve portion 1111 is arranged at the distal end of the first channel 111. When the insertion portion 20 is bent, the first sleeve portion 1111 can be bent along with the bending of the insertion portion 20. Part of the energy transmitted from the distal end to the proximal end of the insertion portion 20 can be absorbed by the first sleeve portion 1111, so that the influence of the bending of the insertion portion 20 on the sealing performance of the connection between the elastic body 110 and the shell 11 can be reduced.

[0037] In some embodiments, the second channel 112 is provided with a second sleeve portion 1121 at the distal end, and the second sleeve portion 1121 is in communication with the second channel 112, as shown in FIGS. 3-5. For example, the second sleeve portion 1121 can be formed by extending the second channel 112 distally. Alternatively, the second sleeve portion 1121 can be a structure integrated on the elastic body 110. The second sleeve portion 1121 and the second channel 112 are integrally formed.

[0038] The second sleeve part 1121 is arranged at the distal end of the second channel 112. When the cable 30 is pulled, the second sleeve part 1121 can be bent along with the pulling of the cable 30. The second sleeve part 1121 can absorb part of the energy transmitted from the distal end to the proximal end of the cable 30, so as to reduce the influence of the pulling of the cable 30 on the sealing of the connection between the elastic body 110 and the shell 11.

[0039] In some embodiments, the first sleeve part 1111 is further provided with a first slot 1111a, and / or the second sleeve part 1121 is further provided with a second slot 1121a, as shown in FIG. 4. FIG. 4 shows a schematic view in which the first sleeve part 1111 is further provided with the first slot 1111a, and the second sleeve part 1121 is provided with the second slot 1121a. Not limited to this, the first sleeve part 1111 can be further provided with the first slot 1111a only, or the second sleeve part 1121 can be further provided with the second slot 1121a only.

[0040] In some embodiments, the first slot 1111a can be arranged in the axial direction of the first sleeve part 1111, or can be arranged in the radial direction of the first sleeve part 1111. There can be one or more first slots 1111a.

[0041] In some embodiments, the second slot 1121a can be arranged in the axial direction of the second sleeve part 1121, or can be arranged in the radial direction of the second sleeve part 1121. There can be one or more second slots 1121a.

[0042] The first sleeve part 1111 is provided with the first slot 1111a, which can avoid the problem that the rigidity of the first sleeve part 1111 is too large, and the first sleeve part 1111 limits the bending of the proximal end of the insertion part 20. The second sleeve part 1121 is provided with the second slot 1121a, which can avoid the problem that the rigidity of the second sleeve part 1121 is too large, and the proximal end of the cable 30 is limited to bend, and the proximal end of the cable 30 is prone to breakage.

[0043] In some embodiments, the elastic body 110 is further provided with a clamping part 113, as shown in FIGS. 3 and 4. The clamping part 113 is arranged in the axial direction of the elastic body 110, and the clamping part 113 is clamped with the shell 11, as shown in FIGS. 1 and 2. Correspondingly, the shell 11 is provided with a missing slot 11-5, as shown in FIG. 8. The missing slot 11-5 is used to accommodate the clamping part 113, as shown in FIG. 2. Through the arrangement of the clamping part 113, the elastic body 110 and the shell 11 are not only connected in the circumferential direction, but also connected in the axial direction. When the elastic body 110 is installed, the clamping part 113 can also play a guiding role.

[0044] In some embodiments, the clamping portion 113 is further provided with a protrusion 1131, as shown in FIG. 3 and FIG. 4. The protrusion 1131 protrudes from the surface of the elastic body 110, and the first channel 111 and / or the second channel 112 is at least partially located at the protrusion 1131. For example, the height of the protrusion 1131 gradually increases from the proximal end to the distal end of the elastic body 110, as shown in FIG. 3 and FIG. 4. For example, the clamping portion 113 is arranged on the side of the elastic body 110 with the first channel 111, and the first channel 111 is at least partially located at the protrusion 1131; and / or the clamping portion 113 is arranged on the side of the elastic body 110 with the second channel 112, and the second channel 112 is at least partially located at the protrusion 1131.

[0045] The first channel 111 and / or the second channel 112 of the present embodiment is at least partially located at the protrusion 1131, which can further reduce the influence of the bending of the insertion portion 20 and / or the pulling of the cable 30 on the sealing performance of the connection between the elastic body 110 and the shell 11.

[0046] In some embodiments, the elastic body 110 is further provided with a first clamping groove 114 and a second clamping groove 115, as shown in FIG. 4. The shell 11 includes a first shell 11-1 and a second shell 11-2, as shown in FIG. 2. The first shell 11-1 is provided with a first clamping block 11-3, and the second shell 11-2 is provided with a second clamping block 11-4, as shown in FIG. 6-FIG. 8. The first clamping groove 114 is clamped with the first clamping block 11-3, and the second clamping groove 115 is clamped with the second clamping block 11-4. By clamping the first clamping groove 114 with the first clamping block 11-3 and clamping the second clamping groove 115 with the second clamping block 11-4, the connection between the elastic body 110 and the shell 11 can be realized by the structure of the elastic body 110 and the shell 11, and the stability of the connection between the elastic body 110 and the shell 11 can be enhanced.

[0047] In some embodiments, the first clamping groove 114 and / or the second clamping groove 115 is arranged obliquely in the radial direction of the shell 11. As shown in FIG. 4, the first clamping groove 114 and the second clamping groove 115 are both arranged obliquely in the radial direction of the shell 11. Referring again to FIG. 4, from the proximal end to the distal end of the elastic body 110, and in the installation direction of the second shell 11-2 (which can also be said to be the direction from the upper side to the lower side of the elastic body 110), the first clamping groove 114 and the second clamping groove 115 are obliquely downward.

[0048] The first clamping groove 114 and the second clamping groove 115 are inclined, which is conducive to the clamping of the first clamping groove 114 and the first clamping block 11-3 when the elastic body 110 is assembled on the first shell 11-1, and is conducive to the clamping of the second clamping groove 115 and the second clamping block 11-4 when the second shell 11-2 is assembled on the elastic body 110. On the other hand, the inclined arrangement of the first clamping groove 114 and the second clamping groove 115 can further enhance the stability of the connection between the elastic body 110 and the shell 11.

[0049] In some embodiments, the first clamping groove 114 further has a first sealing glue layer, and the first clamping groove 114 and the first clamping block 11-3 are fixedly connected through the first sealing glue layer, thereby further enhancing the stability of the connection between the elastic body 110 and the first shell 11-1.

[0050] In some embodiments, the second clamping groove 115 has a second sealing glue layer, and the second clamping groove 115 and the second clamping block 11-4 are fixedly connected through the second sealing glue layer, thereby further enhancing the stability of the connection between the elastic body 110 and the second shell 11-2.

[0051] In some embodiments, the elastic body 110 further has an abutting surface 116, as shown in FIG. 3. When the elastic body 110 is clamped with the shell 11, the distal end surface of the shell 11 abuts against the abutting surface 116, as shown in FIG. 2. Through the arrangement of the abutting surface 116, the abutting surface 116 can play a positioning role when the elastic body 110 is assembled, and the sealing between the shell 11 and the elastic body 110 can be enhanced through the abutment of the shell 11 and the abutting surface 116.

[0052] In some embodiments, the elastic body 110 further has a missing groove 117, as shown in FIG. 3. The number of the missing groove 117 is one or more. Through the arrangement of the missing groove 117, the amount of material used in the production of the elastic body 110 can be reduced, and the production cost can be reduced. On the other hand, through the arrangement of the missing groove 117, the elasticity of the elastic body 110 can be increased, so that the elastic body 110 has greater deformation ability, which can further reduce the influence of the bending of the insertion part 20 on the sealing of the connection between the elastic body 110 and the insertion part 20, and can further reduce the influence of the pulling action of the cable 30 on the sealing of the connection between the elastic body 110 and the cable 30.

[0053] The endoscope of the present embodiment comprises a handle 10, an insertion part 20 and a cable 30, and the insertion part 20 and the cable 30 are connected with the handle 10, as shown in FIG. 1. The endoscope further comprises the elastic connecting piece of any one of the technical solutions of the present embodiment, and the elastic connecting piece is arranged at the distal end of the handle 10, as shown in FIG. 1.

[0054] The endoscope of the embodiment can reduce the influence of the bending of the insertion part 20 on the sealing performance of the connection between the elastic body 110 and the insertion part 20, and can also reduce the influence of the pulling of the cable 30 on the sealing performance of the connection between the elastic body 110 and the cable 30.

[0055] The above merely describes the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
