Technical Field

[0040] The utility model discloses an interface for an endoscope and an endoscope device, so that the interface and the endoscope body can be overlapped stably and reliably, thereby improving the reliability and effectiveness of electrostatic conduction between the two.
[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0042] The endoscope system mainly includes an endoscope device (such as an all-in-one machine, a cold light source, etc.) and an endoscope. An endoscope interface 100 is provided on the endoscope device to connect with the endoscope, such as connecting with the light guide rod of the hard mirror body, or connecting with the light guide part of the soft mirror body, so as to achieve light guide, gas guide and communication connection. Generally, the soft mirror body includes: an insertion part, an operating part and a light guide part. The light guide part is connected to the endoscope interface of the light source as a plug of the endoscope, and the light source is connected to the host through a rear-end cable. Therefore, the following takes the endoscope device as a cold light source and the plug of the endoscope as the light guide part as an example to introduce the embodiment of the utility model in detail.
[0043] Specifically, see Figure 1-Figure 3 The interface 100 for endoscopes of cold light sources is provided with an electrical connector to contact and conduct with the electrical connector on the endoscope. The electrical connector on the cold light source can specifically be a pin needle 111, the interface body 110 is provided with a needle seat 112, the pin needle 111 is installed on the needle seat 112, and the printed circuit board 113 is arranged at the other end of the needle seat 112 and is electrically connected to the pin needle. The electrical connector on the endoscope can be a solid needle 210, and is arranged on a solid needle base 230. After the light guide part of the endoscope is inserted into the interface 100 for endoscopes of cold light sources, the connecting ring 220 on the light guide part is fixed by the clamping part 121 such as a steel ball on the interface 100 for endoscopes, and at the same time, the electrical connector on the endoscope is in contact and conducts with the electrical connector of the interface 100 for endoscopes.
[0044] After the light guide of the endoscope is inserted into the endoscope interface 100 of the cold light source, in theory, the electrostatic discharge path on the endoscope is divided into two parts, one part from the front end face of the connecting ring 220 to the inner end face of the clamping ring 120 of the endoscope interface 100, and the other part from the connecting ring 220 to the clamping ring 120 through the steel ball in the circumferential direction. Then it is input into the housing ground through the floating ground piece 170, the safety capacitor 180, the solid piece 190 and the like on both sides of the clamping ring 120. However, considering that the user's hand feel should not be too strong for plugging and unplugging, there will be a balance between the clamping force of the steel ball on the light guide and the reverse thrust of all the pins 111 on the endoscope interface 100, resulting in a certain gap between the end face of the connecting ring 220 and the inner end face of the clamping ring 120 of the endoscope interface 100, and finally resulting in the electrostatic discharge path can only be discharged through the point contact between the steel ball and the connecting ring 220, and the contact surface between the two is relatively small, which affects the discharge of static electricity of the endoscope.
[0045] The endoscope interface provided in the present application is applicable to but not limited to endoscope equipment such as cold light sources, so as to be connected to the plug 200 of the endoscope, and is particularly suitable for being connected to the light-guiding part of the flexible endoscope body, thereby achieving stable and reliable overlap and forming two complete and reliable electrostatic discharge paths between the endoscope and the endoscope interface.
[0046] Specifically, see Figure 4-Figure 6The interface for endoscope provided by the utility model comprises an interface body 110, a clamping ring 120 and an elastic contact member 130. The interface body 110 is used to realize at least one of light guide, gas guide and communication connection when the interface 100 and the plug 200 are plugged in. It is specifically set according to the functional requirements of the interface 100 and the plug 200, and it may specifically include a pin 111, a pin seat 112, a printed circuit board 113, a connecting ring 114, a guide seat 115 and other structures. The clamping ring 120 is arranged on the interface body 110 and is connected to the ground, and is used to plug the plug 200. Specifically, the plug 200 and the clamping ring 120 are matched along the radial clearance of the clamping ring 120, and a clamping portion 121 for clamping with the plug 200 is provided on the inner wall surface of the clamping ring 120. The clamping portion 121 can specifically adopt a steel ball and cooperate with the guide block 124, or the clamping portion 121 can also adopt other clamping structures that can cooperate with the plug 200. The elastic contact member 130 includes a fixed section 131 and a cantilever section 132 connected to each other. The fixed section 131 is fixed to the collar 120 or the interface body 110, and the cantilever section 132 is in contact with the plug 200 when the plug 200 is fixed to the collar 120. Among them, the fixed section 131 can be fixed to the collar 120, and the peripheral surface of the cantilever section 132 can be in contact with the plug 200, with a larger contact area and higher reliability. And because the direction of the force exerted by the cantilever section 132 on the plug is different from the plug-in and pull-out direction, the impact on the conventional locking state is smaller. Alternatively, the fixed section 131 can also be fixed to the interface body 110, and the cantilever section 132 can be in contact with the front end surface of the plug 200, and contact conduction can also be achieved.
[0047] At least part of the collar 120 and at least part of the elastic contact 130 are made of conductive material, that is, at least the part of the collar 120 that contacts the elastic contact 130 is made of conductive material, and at least the part of the elastic contact 130 that contacts the collar 120 and the part that contacts the plug 200 is made of conductive material, so that a conductive link is formed between the collar 120 and the elastic contact 130 and between the elastic contact 130 and the plug 100, so that when the plug 200 is fixed to the collar 120, the plug 200 can be connected to the collar 120 through the elastic contact 130, and then connected to the housing ground through the floating ground sheet 170, the safety capacitor 180, the solid ground sheet 190, etc., thereby realizing static discharge. It can be understood that the collar 120 and the elastic contact 130 can be made of metal as a whole, or can be made of conductive materials such as metal or conductive coating at the contact part and the local part between different contact parts, as long as it can ensure that there is a conductive link between different contact parts. Of course, those skilled in the art will appreciate that the portions of the retaining ring 120 that are in contact with the floating ground piece 170 , the safety capacitor 180 , and the solid ground piece 190 also need to be made of conductive material, and a conductive link needs to be formed between the contact portions of the retaining ring 120 and the elastic contact piece 130 and the contact portions of the retaining ring 120 and the floating ground piece 170 , the safety capacitor 180 , and the solid ground piece 190 .
[0048] The endoscope interface provided by the utility model can realize the light-guiding, air-guiding or communication connection with the scope, and the clamp ring and the scope plug 200 are reliably and stably locked. By setting the elastic contact piece 130, the fixed section 131 of which is fixed on the clamp ring 120 or the interface body 110, and the cantilever section 132 can contact the plug 200, so that the plug 200 is connected with the clamp ring 120 through the elastic contact piece 130, the effective contact area between the interface and the scope is increased, the static discharge path is guaranteed, and the reliability of the product is improved. At the same time, the cantilever section 132 is easy to deform, so it is much smaller than the blocking effect of the clamping part 121 on the plug 200, so the operator can still maintain a good plugging and unplugging feel.
[0049] In some embodiments, the free end of the cantilever section 132 is closer to the interface body 110 than the end connected to the fixed section 131. That is, the cantilever section 132 extends from the end connected to the fixed section 131 to the free end along the insertion direction of the plug 200. That is, the overall direction from the end connected to the fixed section 131 to the free end of the cantilever section 132 is roughly the same as the insertion direction of the plug 200. In the process of inserting the plug 200, the cantilever section 132 can conform to the insertion of the plug 200 and start to deform from the end connected to the fixed section 131, which will not cause obstruction to the insertion of the plug 200, thereby not affecting the insertion feel of the plug 200. In other embodiments, when the elastic contact member 130 is relatively elastic and is not likely to cause resistance to the plug 200, the extension direction of the cantilever section 132 is not limited to the above setting.
[0050] In some embodiments, the interface 100 for endoscope may include a plurality of elastic contacts 130, and the plurality of elastic contacts 130 are spaced apart along the inner circumference of the collar 120. By distributing the plurality of elastic contacts 130 at intervals, on the one hand, a larger contact area with the plug 200 can be provided, thereby improving the reliability of electrostatic discharge. On the other hand, the elastic contacts 130 distributed at intervals are more likely to bend and deform naturally to adapt to the outer circumference of the plug 200, and fit well with the outer circumference of the plug 200. The width of the interval may be smaller than the width of the elastic contact 130, so as to improve the overall elasticity of the elastic contact 130 while ensuring the contact area between the elastic contact 130 and the plug 200. Specifically, the plurality of elastic contacts 130 may be evenly spaced apart along the inner circumference of the collar 120. Thus, the elastic contact 130 can maintain effective contact from different directions of the outer circumference of the plug 200, thereby increasing the contact area between the elastic contact 130 and the plug 200, and making the contact state in each direction the same when the plug 200 is inserted, thereby improving the stability of the performance of the plug 200. For example, the elastic contact member 130 may be arranged within a certain circumferential angle range corresponding to the clamp ring 120 , such as elastic contact members 130 of a certain length may be arranged at positions 0°, 90°, 180°, and 270° of the clamp ring 120 .
[0051] In some embodiments, at least part of the structure of the fixed section 131 of each elastic contact 130 is interconnected to form an integrated annular structure. Accordingly, the cantilever section 132 of each elastic contact 130 is spaced apart along the circumference of the collar 120. The fixed section 131 is annular and sleeved in the collar 120 for easy assembly, and the cantilever sections 132 spaced apart are easy to deform when plugged into the plug 200. In other embodiments, each elastic contact 130 can also be spaced apart as a whole, that is, each elastic contact 130 is distributed on the inner circumference of the collar 120 as an independent unit.
[0052] In some embodiments, the middle portion of the cantilever section 132 is arc-shaped and convex inwardly along the radial direction of the collar 120. It can be understood that the convex inwardly along the radial direction of the collar 120 is to convex in the direction of the central axis of the collar 120. That is, the middle portion of the cantilever section 132 has an arc-shaped portion 1321 convex inwardly. By setting the middle portion of the cantilever section 132 to extend in an arc shape, when the plug 200 is inserted, a line contact is formed with the plug 200, and the friction is small, thereby avoiding scratching the outer peripheral surface of the plug 200 and reducing the impact on the plug and unplug operation feel. In the process of inserting the plug 200, it further helps the cantilever section 132 to deform elastically, thereby finally forming a surface contact with the plug 200 for reliable electrical conduction. In other embodiments, when the elastic contact member 130 is relatively elastic and is not easy to cause resistance to the plug 200, the cantilever section 132 can be a straight line segment or a curved segment of other shapes.
[0053] In some embodiments, the cantilever section 132 is used to make surface contact with the plug 200 to further increase the contact area and improve the reliability and effectiveness of the system's electrostatic discharge.
[0054] In some embodiments, a receiving groove 122 is provided on the inner wall surface of the collar 120, the receiving groove 122 is spaced apart from the clamping portion 121 along the axial direction of the collar 120 and is close to the interface body 110 relative to the clamping portion 121, the fixing section 131 is fixedly provided in the receiving groove 122, and at least part of the cantilever section 132 protrudes from the notch of the receiving groove 122. Specifically, the elastic contact member 130 can be roughly L-shaped or U-shaped, one side of the L-shape is the fixing section 131, and is fixedly connected to the side wall of the receiving groove 122, and the other side is the cantilever section 132, and extends toward the insertion direction of the plug 200, so that during the insertion process of the plug 200, while the plug 200 is engaged with the collar 120, its outer peripheral surface can abut against the cantilever section 132. When the elastic contact piece 130 is U-shaped, one of the vertical sides of the U-shape is the fixed section 131 and is fixedly connected to the bottom of the accommodating groove 122, and the other vertical side and the horizontal side are the cantilever section 132, or one of the vertical sides and / or the horizontal side of the U-shape is the fixed section 131, the vertical side is fixedly connected to the bottom of the accommodating groove 122, and / or the horizontal side is fixedly connected to the side wall of the accommodating groove 122, and the other vertical side is the cantilever section 132, and the extension direction of the cantilever section 132 is specifically along the insertion direction of the plug 200, that is, the axial direction of the clamping ring 120, so that during the insertion process of the plug 200, the plug 200 can be engaged with the clamping ring 120 and can abut against the cantilever section 132. It is understandable that the extension of the cantilever section 132 along the insertion direction does not require the cantilever section 132 to be parallel to the insertion direction, but refers to the same direction (the free end of the cantilever section 132 is relative to the connection end of the fixed section 131, close to the interface body 110, that is, located in front of the insertion direction), and can be inclined at a certain angle relative to the insertion direction. Among them, the bottom of the groove 122 can be along the circumference of the clamp ring 120, and the side wall is along the radial direction of the clamp ring 120. It is understandable that the L-shape and U-shape refer to the main shape of the elastic contact member 130, and are not used to limit that each segment is a straight line segment. Through the provision of the accommodating groove 122, space is reserved for the installation of the elastic contact member 130, and at least part of the cantilever section 132 protrudes from the notch of the accommodating groove 122. During the insertion process of the plug 200, it can fully contact the cantilever section 132, thereby improving the reliability of electrostatic discharge.
[0055] In some embodiments, the receiving groove 122 is disposed at one end where the collar 120 is connected to the interface body 110, and one end of the receiving groove 122 extends to the end surface of the collar 120. The above arrangement facilitates the installation of the elastic contact member 130, and the overall structure is more compact.
[0056] In some embodiments, the endoscope interface further includes a sleeve 140 and an adapter ring 150. The sleeve 140 is sleeved in the receiving groove 122, and the fixed section 131 is clamped between the matching surfaces of the sleeve 140 and the collar 120; the adapter ring 150 is fixed between the interface body 110 and the collar 120, and presses the sleeve 140. The collar 120 and the adapter ring 150 are matched, and the collar 120 is fixedly connected to the interface body 110 through the adapter ring 150, and the adapter ring 150 and the collar 120 press and fix the sleeve 140, and the sleeve 140 presses the fixed section 131 between it and the collar 120, thereby achieving the fixation of the fixed section 131. The above structure is adopted to facilitate the assembly of various components, and when the plug 200 is inserted, the plug 200 forms good contact with the cantilever section 132, and under the extrusion of the sleeve 140, the cantilever section 132 forms good contact with the retaining ring 120, which can be surface contact, thereby improving the reliability and effectiveness of the electrostatic discharge of the system. Specifically, the adapter ring 150 can press the sleeve 140 along the axial direction of the retaining ring 120, and the sleeve 140 correspondingly presses the elastic contact member 130 to the retaining ring 120 along the axial direction, and the axial compression is used to facilitate assembly. In other embodiments, the fixed section 131 can also be directly bonded to the inner wall of the retaining ring 120 by conductive adhesive.
[0057] In some embodiments, the mating surface includes the circumferential mating surface and / or the axial mating surface of the sleeve 140 and the retaining ring 120. The sleeve 140 presses the fixing section 131 against the end surface of the retaining ring 120 at one end facing the retaining ring 120, or the outer circumferential surface of the sleeve 140 presses the fixing section 131 against the inner circumferential surface of the retaining ring 120 to ensure reliable contact between the fixing section 131 and the retaining ring 120. When the retaining ring 120 is provided with a receiving groove 122 and the elastic contact member 130 is L-shaped or U-shaped, when the elastic member is L-shaped, the mating surface is the axial mating surface between the sleeve 140 and the retaining ring 120, that is, the sleeve 140 presses one side of the L-shape against the side wall of the receiving groove 122 at one end facing the retaining ring 120 to achieve reliable surface contact between the fixing section 131 and the retaining ring 120. When the elastic contact piece 130 is U-shaped, the mating surface may include the circumferential mating surface and / or the axial mating surface between the sleeve 140 and the retaining ring 120, that is, the sleeve 140 presses the horizontal edge of the U-shape against the side wall of the accommodating groove 122 toward one end of the retaining ring 120, and the outer peripheral surface of the sleeve 140 presses one of the vertical edges of the U-shape against the bottom of the accommodating groove 122, thereby further increasing the contact area between the fixed section 131 and the retaining ring 120.
[0058] In some embodiments, the middle portion of the cantilever section 132 is arc-shaped, and an avoidance space 160 is formed between the sleeve 140 and the adapter ring 150. By setting the avoidance space 160 between the sleeve 140 and the adapter ring 150, when the plug 200 is inserted into the endoscope interface, it squeezes the cantilever section 132 to deform. For example, when the middle portion of the cantilever section 132 is arc-shaped and convex inward along the radial direction of the collar 120, the arc-shaped portion is squeezed by the plug 200 and unfolds, so that the free end can extend into the avoidance space 160 with the deformation. The setting of the avoidance space 160 further facilitates the elastic deformation of the elastic contact member 130 when the plug 200 is inserted, reducing its influence on the insertion feel of the plug 200. And the avoidance space 160 is set between the sleeve 140 and the adapter ring 150, and the structure is more compact.
[0059] In some embodiments, the adapter ring 150 includes a main body 151 and a protrusion 152 protruding from one end of the main body 151. The outer diameter of the main body 151 is larger than the outer diameter of the protrusion 152 and forms a step surface 153. The step surface 153 abuts against one end of the sleeve 140, and a clearance space 160 is formed between the sleeve 140 and the outer circumference of the protrusion 152. When the plug 200 is inserted, it can abut against the end surface of the protrusion 152, and a clearance space 160 is formed between the outer circumference of the protrusion 152 and the inner circumference of the sleeve 140. The step surface 153 can apply an axial force to the sleeve 140 to compress it. The above arrangement facilitates the matching between the various components.
[0060] In some embodiments, one of the main body 151 and the collar 120 is provided with a positioning protrusion 123, and the other is provided with a positioning groove 154 that cooperates with the positioning protrusion 123. The positioning protrusion 123 and the positioning groove 154 can play a positioning role when the adapter ring 150 and the collar 120 are assembled, which facilitates assembly. Specifically, the collar 120 and the adapter ring 150 can be connected by threads, and the positioning protrusion 123 and the positioning groove 154 are both annular. In other embodiments, the collar 120 and the adapter ring 150 can also be connected by other conventional fixing methods.
