Description

Technical Field

[0001] The invention belongs to the technical field of endoscopes and relates to an optical path connector and an endoscope system. Background Art

[0002] For endoscope systems widely used in the medical field, there is a technology that uses light to transmit image signals / control signals. Usually, an optical path connector 1' is connected to the endoscope host, and an optical path connector 2' is connected to the endoscope body. The optical path connector 1' and the optical path connector 2' are connected through a connector. The structure of the existing connector is as follows: Figure 1 'As shown, it includes a columnar connecting seat 3', one end of the connecting seat 3' has a mounting hole 1 31' arranged to cooperate with the optical path connector 1 ', and the other end has a mounting hole 2 32' arranged to cooperate with the optical path connector 2 ', the mounting hole 1 31' is coaxial with the mounting hole 2 32', and the mounting hole 1 31' is connected with the mounting hole 2 32' through a light guide hole 33'.

[0003] In order to ensure that the optical path connector 1' is coaxial with the optical path connector 2', the inner diameter of the mounting hole 1 31' needs to be close to the outer diameter of the optical path connector 1', and the inner diameter of the mounting hole 2 32' needs to be close to the outer diameter of the optical path connector 2 2', which has the following problems: high processing accuracy requirements for the connecting seat 3'; when inserting the optical path connector 2' into the mounting hole 2 32', it is difficult for the operator to align the axis of the optical path connector 2' with the axis of the mounting hole 2 32', resulting in difficulty in inserting the optical path connector 2', causing wear on the outer wall of the optical path connector 2' and the inner wall of the mounting hole 2 32'. After wear, the gap between the two increases, resulting in poor concentricity between the optical path connector 1 ' and the optical path connector 2 2', causing increased light loss. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems in the prior art and to provide an optical connector which can effectively ensure the concentricity of the optical connector.

[0005] An endoscope system that facilitates the connection of optical path joints is also proposed.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] An optical path connector, used to connect optical path connector one with optical path connector two, includes a main body with a mounting hole, a fixing seat is provided in the mounting hole, a middle portion of the fixing seat has a light guide hole coaxially arranged with the mounting hole, a side wall of the light guide hole is provided with a plurality of mounting through grooves distributed in a circular array along the central axis of the light guide hole, a claw block is hinged in the mounting through groove, one end of the claw block has a first clamping plate, and the other end has a second clamping plate parallel to the first clamping plate, a plurality of the first clamping plates constitute a first clamping cylinder for clamping optical path connector one, a plurality of the second clamping plates constitute a second clamping cylinder for clamping optical path connector two, and a traction structure is provided on the main body for tilting the first clamping plate and the second clamping plate relative to the central axis of the light guide hole.

[0008] The optical path connector 1 and the optical path connector 2 have the same structure and are equal in size. The connector can ensure the coaxiality of the optical path connector 1 and the optical path connector 2. The main body is columnar, the mounting hole is coaxially arranged with the main body, the fixing seat is located inside the mounting hole, there is a distance between the fixing seat and one end of the main body, and there is also a distance between the fixing seat and the other end of the main body. The aperture of the light guide hole is smaller than the outer diameter of the optical path connector 1 and the optical path connector 2, the end faces of the fixing seat are parallel to each other, and the end faces of the fixing seat are perpendicular to the central axis of the light guide hole. After the optical path connector 1 and the optical path connector 2 are connected through the connector, the optical path connector 1 rests on one end face of the fixing seat, and the other optical path connector rests on the other end face of the fixing seat. Only one claw block is hinged in each mounting slot, and a number of claw blocks located in different mounting slots are distributed in a circular array along the central axis of the light guide hole.

[0009] When the optical path connector 1 and the optical path connector 2 are not connected in place, the traction structure makes the first clamping plate and the second clamping plate tilt relative to the central axis of the light guide hole, and the first clamping tube composed of a plurality of first clamping plates is in a cone shape, and the second clamping tube composed of a plurality of second clamping plates is in a cone shape. When the optical path connector 1 and the optical path connector 2 are connected in place, the first clamping plate is parallel to the central axis of the light guide hole, the first clamping tube is in a cylindrical shape and clamps the optical path connector coaxially, and the second clamping tube is in a cylindrical shape and clamps the optical path connector coaxially. At this time, the first clamping tube is coaxial with the second clamping tube, and the inner diameters of the first clamping tube and the second clamping tube are larger than the aperture of the light guide hole.

[0010] The traction structure can be arranged between the body and the first clamping plate, or between the body and the second clamping plate, or between the body and the claw block, or between the fixing seat and the first clamping plate, or between the fixing seat and the second clamping plate, or between the fixing seat and the claw block.

[0011] In the above-mentioned optical path connector, a plurality of limit columns corresponding to the second clamping plates are fixed to the inner wall of the mounting hole, and the limit columns extend radially along the mounting hole. When the first clamping plate is parallel to the axis of the light guide hole, the vertical distance from the first clamping plate to the inner wall of the mounting hole is greater than the length of the limit columns. Under the action of the traction structure, the second clamping plate rests on the limit columns corresponding to it, and a yield structure is provided between the first clamping plate and the optical path connector.

[0012] The limiting column can limit the maximum tilt angle of the second clamping plate. The limiting columns are distributed in a circular array along the central axis of the light guide hole. When the second clamping plate abuts against the limiting column corresponding to it, the tilt angles of the second clamping plates are the same. At this time, the first clamping tube composed of the first clamping plates is in a conical shape, and the second clamping tube composed of the second clamping plates is in a conical shape. The diameter of the end of the second clamping tube away from the claw block is larger than the outer diameter of the optical path connector 2, which is convenient for inserting the optical path connector 2 into the second clamping tube; the diameter of the end of the first clamping tube away from the claw block is smaller than the outer diameter of the optical path connector 1, so a yielding structure is set between the two to facilitate inserting the optical path connector 1 into the first clamping tube.

[0013] In the above optical connector, the said giving way structure comprises a guiding inclined surface arranged at an end of the first clamping plate away from the claw block and / or an end of the optical connector.

[0014] The guiding bevel can be arranged at one end of the first clamping plate away from the clamping claw block, or at the end of the optical path connector 1, or at both the end of the first clamping plate away from the clamping claw block and the end of the optical path connector 1. Its function is to introduce the end of the optical path connector 1 into the first clamping barrel, and then under the squeezing action of the optical path connector 1, drive each clamping claw block to swing, so that the second clamping barrel becomes cylindrical to clamp the optical path connector 2, and at the same time, the first clamping barrel becomes cylindrical to clamp the optical path connector 1.

[0015] In the above optical connector, the traction structure includes a plurality of tension springs 1 arranged one-to-one corresponding to the second clamping plates, one end of the tension spring 1 is fixed to the inner wall of the mounting hole, and the other end is fixedly connected to the second clamping plate arranged correspondingly thereto.

[0016] When the tension spring is in a tensioned state, it always has a force to pull the second clamping plate to tilt. In order to make the force direction of the second clamping plate perpendicular to the rotation center line of the claw block and ensure that the force on the second clamping plate is balanced, a set of tension springs is arranged on the corresponding limit columns.

[0017] In the above optical connector, the pulling structure includes a magnet 1 arranged on the body and a magnet 2 arranged on the second clamping plate, and the magnet 1 and the magnet 2 attract each other. The magnet 1 and the magnet 2 have magnetic attraction force, which can drive the second clamping plate to tilt.

[0018] A pin shaft perpendicular to the central axis of the light guide hole is arranged in the installation slot, and the claw block is sleeved on the pin shaft. At this time, the traction structure includes a torsion spring arranged between the fixing seat and the claw block, and the torsion spring is sleeved on the pin shaft.

[0019] In the above-mentioned optical path connector, the first clamping plate has a plurality of protrusions 1 extending along its width direction, and the second clamping plate has a plurality of protrusions 2 extending along its width direction. When the optical path connector 1 and the optical path connector 2 are connected in place, a plurality of protrusions 1 simultaneously abut against the optical path connector 1, and a plurality of protrusions 2 simultaneously abut against the optical path connector 2.

[0020] In the above-mentioned optical connector, the number of the mounting through slots is 3-6.

[0021] In the above optical connector, there are three mounting slots.

[0022] In the above optical connector, the mounting hole has a limiting protrusion, and an elastic traction component is provided between the body and the fixing seat for making the fixing seat lean against the limiting protrusion. There are 2-6 limiting protrusions, which are symmetrically distributed along the central axis of the light guide hole. Under the action of the elastic traction component, the fixing seat has a tendency to move toward one end of the optical connector, and makes the fixing seat lean against a plurality of limiting protrusions.

[0023] In the above-mentioned optical path connector, the main body is provided with a baffle plate at one end where the first clamp is provided, the middle part of the baffle plate has a pre-guide hole coaxially arranged with the light guide hole, the aperture of the pre-guide hole is larger than the outer diameter of the optical path connector, and the elastic traction component is arranged between the baffle plate and the fixed seat.

[0024] In the above optical connector, the elastic traction assembly includes a plurality of tension springs 2 evenly distributed along the central axis of the light guide hole, one end of the tension spring 2 is fixed on the fixed seat, and the other end is fixed on the baffle 1. The tension spring 2 is in a stretched state and has a tendency to drive the fixed seat to move toward the baffle 1.

[0025] In the above optical connector, the body is provided with a baffle plate 2 at one end where the second clamp is provided, and the middle part of the baffle plate 2 has a pre-guide hole 2 coaxially arranged with the light guide hole, and the aperture of the pre-guide hole 2 is larger than the outer diameter of the optical connector 2.

[0026] When the connector is in the initial state, the tension spring 1 pulls the second clamping plate corresponding to it, so that the second clamping plate is tilted relative to the central axis of the light guide hole. When connecting, first insert the optical path connector 2 into the installation hole along the pre-guide hole 2 until the optical path connector 2 abuts against the fixing seat, and then insert the optical path connector 1 into the installation hole along the pre-guide hole 1. During the insertion process, the optical path connector 1 enters between the first clamping plates under the action of the guiding inclined surface, and the claw block is driven to swing around the pin shaft under the extrusion of the optical path connector 1, so that the second clamping plates gradually clamp the pipeline connector 2. When the optical path connector 1 is plugged into place, the optical path connector 1 abuts against the fixing seat, the first clamping tube is cylindrical and clamps the optical path connector coaxially, and the second clamping tube is cylindrical and clamps the optical path connector coaxially, so that the optical path connector 1 is coaxial with the optical path connector 2.

[0027] In order to eliminate the dimensional deviation of optical connector 1 and optical connector 2 in the axial direction caused by manufacturing and installation errors, and at the same time set a certain force buffer for the insertion action, when optical connector 1 is inserted to abut against the end face of the fixed seat, the fixed seat can move axially due to the elasticity of the second tension spring, thereby achieving force buffering and ensuring the relative distance between optical connector 1 and optical connector 2. When optical connector 1 is pulled out, the fixed seat is reset under the action of the second tension spring; the claw block is reset under the action of the first tension spring.

[0028] The endoscope system comprises an endoscope host and an endoscope body, wherein the endoscope host is provided with an optical path connector 2, and the endoscope body is provided with an optical path connector 1, and the optical path connector 2 is connected with the optical path connector 1 through the above-mentioned optical path connector.

[0029] Compared with the prior art, this optical connector has the following advantages:

[0030] Wear can be reduced during connection. The claw block and the tension spring 1 are used to eliminate the coaxiality error caused by the manufacturing error and the assembly error, so that the operator does not need to deliberately align the insertion direction when performing the insertion action, and the concentricity of the optical path connector 1 and the optical path connector 2 is automatically guaranteed; the fixed seat and the tension spring 2 are used to automatically ensure the end face distance between the optical path connector 1 and the optical path connector 2; the operator can make the insertion action simple and easy, with less wear, less light loss and high reliability.

The connector can ensure the coaxiality of the optical path connector 1 and the optical path connector 2.

[0046] The body 4 is columnar, the mounting hole 3 is coaxially arranged with the body 4, the fixing seat 5 is located inside the mounting hole 3, and there is a distance between the fixing seat 5 and one end of the body 4, and there is also a distance between the fixing seat 5 and the other end of the body 4.
