Description

TECHNICAL FIELD

[0001] The utility model relates to medical apparatus and particularly to the technical field of endoscope anastomat, especially to an endoscope fixing support trigger switch plunger assembly mechanism. BACKGROUND

[0002] Endoscope anastomat is a common instrument in endoscopic surgery. In the endoscope anastomat, the handle position of the anastomat fixing support needs to trigger a switch plunger, an active structure. The main function of the trigger switch plunger is to control the firing process of the endoscope anastomat.

[0003] When the doctor needs to anastomatize the tissue, he will press or move the plunger, triggering the mechanism inside the anastomat, so that it completes the cutting, suturing or stapling action. The plunger pin is also assembled on the trigger switch plunger. The plunger pin is connected or adjacent to the trigger switch plunger, used to transmit force or signal. When the trigger switch plunger is pressed or moved, it will transmit force or signal to the internal mechanism of the anastomat through the plunger pin, triggering the firing process. The plunger pin also plays the role of fixing and supporting the trigger switch plunger, ensuring its stable and reliable work during the operation.

[0004] Specifically, during the operation, the endoscope anastomat is placed at the tissue site that needs to be anastomatized, the trigger switch plunger is in the inactive state, and the plunger pin is also in the initial position. When anastomatizing, press or move the trigger switch plunger, the plunger pin will displace or rotate, thereby transmitting force or signal to the internal trigger structure of the anastomat. The internal trigger structure is activated to make the cutting action of the blade, the release of the staple and the completion of the stapling action. After the action is completed, release the trigger switch plunger to return to the inactive state, and the plunger pin returns to the initial position.

[0005] Therefore, the assembly of the plunger and the plunger pin at the trigger switch position of the endoscope fixing support is crucial. At the same time, since the plunger and the plunger pin are small in size, how to support or clamp the plunger pin so that it can be positioned and installed with the plunger becomes a problem to be solved. UTILITY MODEL CONTENTS

[0006] The technical problem to be solved by the utility model is: in order to overcome the shortcomings of the prior art, the utility model provides an endoscope fixing support trigger switch plunger assembly mechanism, which can effectively position and support the plunger, and can drive the plunger pin to be positioned and assembled with the trigger switch plunger pin fixed on the fixing support conveniently and quickly, the assembly process is convenient and fast, the assembly efficiency is high and the assembly quality is stable and reliable.

[0007] The utility model discloses a technical scheme that solves its technical problem is: a laparoscope fixed support excitation switch plunger pin assembly mechanism, for laparoscope fixed support excitation switch's plunger pin assembly plunger, and the assembly mechanism includes the positioning bottom plate, be equipped with the positioning mechanism of the positioning bottom plate on the positioning of laparoscope fixed support and the elevation of the supporting, be equipped with the supporting bracket, moving mechanism and trajectory control assembly on the positioning bottom plate, the plunger is set up on the supporting bracket, the moving mechanism includes horizontal translation mechanism and vertical moving mechanism, the horizontal translation mechanism includes the translation guide rail and the mobile seat of sliding cooperation with the translation guide rail, the mobile seat is fixed with the moving shaft, and the supporting bracket is fixed on the mobile seat, the vertical moving mechanism includes the vertical spring, and one end of the vertical spring is elastically connected with the positioning bottom plate, and the other end is elastically connected with the horizontal translation mechanism, the trajectory control assembly includes the trajectory control box, trajectory control block and reset mechanism, and the trajectory control block is elastically arranged in the trajectory control box through the reset mechanism, the trajectory control block is equipped with the trajectory control groove on, one end of the moving shaft is fixed with the mobile seat, and the other end is limit cooperation with the trajectory control groove.

[0008] In the above scheme, aiming at the problem that the plunger and the plunger pin are not easy to assemble, the moving mechanism is used to drive the plunger and the plunger pin to complete assembly with the trajectory control assembly. In the horizontal motion, the supporting bracket drives the plunger to move horizontally by the design of the track, and the vertical spring is used to complete the movement of the horizontal translation mechanism in the vertical direction. At the same time of displacement, the trajectory control groove is limited, and the reset mechanism drives the moving mechanism to reset after assembly is completed, so that the positioning and assembly of the plunger and the plunger pin can be effectively completed, and the assembly process is convenient and fast.

[0009] Further, the reset mechanism includes a reset optical axis and a reset spring, the trajectory control block has a through hole, the reset optical axis penetrates the through hole of the trajectory control block and is connected with the trajectory control box at both ends, the axis line of the reset optical axis is parallel to the translation direction of the mobile seat, and the reset spring is arranged around the reset optical axis, one end of the reset spring is elastically connected with the trajectory control block near the plunger, and the other end is elastically connected with the trajectory control box body near the end. When the mobile seat drives the moving shaft to move a certain distance along the translation guide rail under the action of external force, the moving shaft is pressed on the groove wall of the trajectory control groove, and the reset spring is compressed when the trajectory control block is horizontally translated. After the plunger and the plunger pin are assembled, the external force of the mobile seat translation is removed, and the mobile seat is reset manually, at this time, the reset spring is reset under the action of the elastic force, and the trajectory control block is reset.

[0010] Further, in order to control the running track of the moving shaft, the track control groove on the track control block is in an L-shaped groove structure, which includes a communicating translation horizontal groove and a moving vertical groove. The translation horizontal groove is parallel to the track of the moving seat along the translation guide rail, and the moving vertical groove is connected to the end of the translation horizontal groove near the toggle. The moving vertical groove is parallel to the central axis of the vertical spring. The translation horizontal groove provides a limit for the early translation of the moving shaft. When the horizontal translation reaches the predetermined position, the moving shaft moves to the connection between the translation horizontal groove and the moving vertical groove. At this time, the vertical spring acts to move the horizontal translation mechanism upward as a whole, thereby driving the toggle to move upward. Then, the moving seat continues to move forward along the translation guide rail to complete the clamping assembly of the toggle and the toggle shaft.

[0011] Further, the horizontal translation mechanism includes a translation base, and the translation guide rail is fixedly arranged on the translation base. The translation base is provided with a vertical annular groove at the lower end. The upper end of the vertical spring is arranged along the vertical annular groove, and the lower end is elastically connected to the positioning base plate, and the upper end is elastically connected to the translation base.

[0012] Preferably, the power for the translation assembly of the moving seat is provided by an assembly handle. The moving seat of the horizontal translation mechanism is fixedly provided with an assembly stopper. The positioning base plate is rotatably connected to the assembly handle through a rotating shaft. When the assembly handle rotates around the rotating shaft as the rotation center, the one end of the assembly handle abuts against the assembly stopper and pushes the assembly stopper, thereby driving the moving seat to slide along the translation guide rail.

[0013] Further, the supporting bracket is provided with a positioning groove corresponding to the profile of the toggle. The groove bottom of the positioning groove has a clearance groove corresponding to the bottom of the opening position of the toggle and the insertion position of the toggle pin. The positioning groove provides a positioning space for the positioning and placement of the toggle. The clearance groove provides a clearance for the clamping of the toggle pin during assembly, thereby avoiding interference with the toggle pin during assembly.

[0014] Preferably, the toggle is in a U-shaped sheet structure. The groove bottom of the positioning groove is also projected as a U-shaped structure corresponding to the outer edge of the toggle. The circumferential four sides of the U-shaped structure are respectively an opening side, an arc-shaped side, and two straight wall sides. The side wall of the positioning groove only has an arc-shaped side wall and a straight wall side wall on one side.

[0015] Further, the positioning mechanism includes a plurality of heightening blocks and a quick clamp. The clamp head of the quick clamp is used to press and position the endoscope fixing support and the heightening block. The heightening block can be used to lift and support the endoscope fixing support, so that the toggle pin assembled at the lower end of the side of the endoscope fixing support can be exposed, thereby facilitating the subsequent toggle assembly operation.

Therefore, the following specific embodiments are not used in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents.

[0029] As Figures 1 to 9 The utility model discloses a kind of endoscope fixed support trigger switch toggle piece pin assembly mechanisms, it is the optimal embodiment of the utility model.The assembly mechanism is used to toggle piece 13 for the toggle piece pin 1 of endoscope fixed support trigger switch assembly toggle piece 13.Toggle piece pin 1 is usually assembled and fixed on endoscope fixed support trigger switch, and lower end exposes from endoscope fixed support.Toggle piece 13 is U-shaped flaky structure, and toggle piece 13 is inserted into and assembled with toggle piece pin 1 from the opening side of U-shaped structure.

[0031] As Figure 9 As shown in the drawings, positioning base plate 2 is equipped with supporting bracket 14, moving mechanism and trajectory control assembly, and toggle piece 13 is arranged on supporting bracket 14.Supporting bracket 14 is equipped with positioning groove corresponding to the profile of toggle piece 13, and the groove bottom of positioning groove has a clearance groove corresponding to the opening position bottom of toggle piece 13 and the insertion position of toggle piece pin 1.When the profile of toggle piece 13 is U-shaped, the groove bottom of positioning groove also projects U-shaped structure to the outer edge of toggle piece 13, and the circumferential four sides of the U-shaped structure are opening side, arc side and two straight wall sides, and the side wall of positioning groove only has arc side side wall and straight wall side side wall on one side.In positioning and placing toggle piece 13, positioning groove provides positioning for toggle piece 13, and clearance groove provides avoidance for the insertion of toggle piece pin 1 during assembly, to avoid interference with toggle piece pin 1 during assembly.The design of the groove wall of positioning groove only has arc side side wall and straight wall side side wall, and opening position and another straight wall side side wall are empty, so that the opening of toggle piece 13 is provided with clearance when being inserted into toggle piece pin 1, to facilitate the combined assembly of toggle piece 13 and toggle piece pin 1.

[0032] Specifically, after the supporting bracket 14 supports the switch blade 13, the switch blade 13 needs to be driven to perform three actions, i.e., driving the switch blade 13 forward, lifting the switch blade 13 upward, and continuing to drive the switch blade 13 forward, so as to complete the assembly of the switch blade 13 and the switch blade pin 1. The three actions need to be realized by cooperation of the moving mechanism and the trajectory control assembly.

[0033] As shown in Figure 3 and Figure 4 , the moving mechanism comprises a horizontal translation mechanism and a vertical moving mechanism. The horizontal translation mechanism comprises a translation base 17, a translation guide rail 3, and a moving seat 9 in sliding cooperation with the translation guide rail 3. The translation guide rail 3 is fixed on the translation base 17, the moving seat 9 is fixed with a moving shaft 12, and the supporting bracket 14 is fixed on the moving seat 9 and driven to move by the moving seat 9. The vertical moving mechanism comprises a vertical spring 16. A vertical annular groove 15 is arranged at the lower end of the translation base 17, used for guiding the connecting end of the vertical spring 16 and the translation base 17. The lower end of the vertical spring 16 is elastically connected with the positioning base plate 2, and the upper end is elastically connected with the translation base 17 along the vertical annular groove 15.

[0034] As shown in Figure 4 , the trajectory control assembly comprises a trajectory control box 6, a trajectory control block 8, and a reset mechanism. The trajectory control block 8 is elastically arranged in the trajectory control box 6 through the reset mechanism. The trajectory control block 8 is provided with a trajectory control groove 7. One end of the moving shaft 12 is fixed with the moving seat 9, and the other end is in limiting cooperation with the trajectory control groove 7. The reset mechanism comprises a reset light shaft 5 and a reset spring 4. The trajectory control block 8 is provided with a through hole. The reset light shaft 5 penetrates the through hole of the trajectory control block 8 and is connected with the trajectory control box 6 at both ends. The axis of the reset light shaft 5 is parallel to the translation direction of the moving seat 9. The trajectory control block 8 can reciprocate along the reset light shaft 5 under the limiting action of the reset light shaft 5. The reset spring 4 is arranged around the reset light shaft 5. One end of the reset spring 4 is elastically connected with the trajectory control block 8 near the switch blade 13, and the other end is elastically connected with the box body of the trajectory control box 6 near the end.

[0035] As shown in Figure 4 , the trajectory control groove 7 on the trajectory control block 8 is in an L-shaped groove structure. The L-shaped groove structure comprises a translation horizontal groove 7-2 and a moving vertical groove 7-1 in communication. The translation horizontal groove 7-2 is parallel to the trajectory of the moving seat 9 moving along the translation guide rail 3. The moving vertical groove 7-1 is connected with the side end of the translation horizontal groove 7-2 near the switch blade 13. The moving vertical groove 7-1 is arranged in parallel with the central axis of the vertical spring 16.

[0036] The moving seat 9 of the transverse translation mechanism is fixed with an assembly stopper 10, and the positioning base plate 2 is rotationally connected with an assembly handle 11 through a rotation shaft. When the assembly handle 11 rotates around the rotation shaft as the rotation center, the side end of the assembly handle 11 abuts against the assembly stopper 10 and pushes the assembly stopper 10, thereby driving the moving seat 9 to slide along the translation guide rail 3. In the embodiment, the height of the assembly stopper 10 needs to be reasonably designed according to the moving track of the moving shaft 12 in the moving vertical groove 7-1, so as to ensure that when the assembly handle 11 abuts against the assembly stopper 10, the assembly stopper 10 will not be affected by the further pressing operation of the assembly handle 11 even if the assembly stopper 10 is integrally moved upward with the moving seat 9.

[0037] The above assembly mechanism has the following operation process:

[0038] The endoscope fixing support assembled with the switch pin 1 is placed on the cushioning block 19, and the quick clamp 18 is used for positioning.

[0039] The switch 13 to be assembled is placed on the supporting bracket 14. At this time, the moving shaft 12 is located at the tail end of the translation horizontal groove 7-2, that is, at the end of the translation horizontal groove 7-2 far away from the switch 13, and the vertical spring 16 is extruded and compressed. At this time, the assembly handle 11 is pulled backward, the front end of the assembly handle 11 pushes the assembly stopper 10 to move forward, the assembly stopper 10 carries the moving seat 9 to move forward along the translation guide rail 3, and the moving shaft 12 also moves forward under the limitation of the translation horizontal groove 7-2, until the moving shaft 12 slides to the front end of the translation horizontal groove 7-2 and the lower end of the moving vertical groove 7-1. Since there is no groove wall limitation of the translation horizontal groove 7-2 above the moving shaft 12 at this time, under the elastic force of the vertical spring 16, the vertical spring 16 drives the whole transverse translation mechanism to act upward, the moving shaft 12 moves upward along the moving vertical groove 7-1, at this time, the switch 13 is lifted under the synchronous movement of the supporting bracket 14, to the height required for the corresponding cooperation of the switch 13 and the switch pin 1. Then, the assembly handle is further pulled backward, the moving shaft 12 continues to extrude the track moving block, the track moving block continues to move forward, while extruding the reset spring 4, and the reset spring 4 is compressed. The switch 13 also moves forward, completing the positioning and assembly with the switch pin 1. After the assembly is completed, the assembly handle 11 is pushed forward, and the moving block is simultaneously pressed downward by hand, on the one hand, the vertical spring 16 is extruded, so as to restore to the original position, on the other hand, the moving shaft 12 moves downward along the moving vertical groove 7-1 to enter the translation horizontal groove 7-2, so that the moving shaft 12 is unlocked. At this time, under the elastic force of the reset spring 4, the reset spring 4 is elastically opened, driving the track control block 8 to move backward to reset. The assembly handle 11 is continuously pushed forward, so that the moving shaft 12 moves backward along the translation horizontal groove 7-2, until the initial position, and is returned to the tail end of the translation horizontal groove 7-2. The quick clamp 18 is released, and the endoscope fixing support assembled with the switch 13 is taken out. The assembly operation of the switch pin 1 and the switch 13 of the endoscope is completed once.

[0040] The switch toggle pin assembly mechanism of the thus designed endoscope fixing support is designed to solve the problem that the toggle 13 and the toggle pin 1 are not easy to assemble, and the toggle 13 and the toggle pin 1 are assembled by the moving mechanism cooperating with the track control assembly. In the transverse movement, the track design can make the supporting bracket 14 drive the toggle 13 to move transversely, and the elastic force of the vertical spring 16 can make the whole transverse translation mechanism move in the vertical direction. At the same time of displacement, the displacement is limited by the track control groove 7, and after assembly is completed, the moving mechanism is reset by the reset mechanism, so that the positioning and assembly of the toggle 13 and the toggle pin 1 can be effectively completed, the assembly process is convenient and fast, and the assembly quality is stable and reliable.

[0041] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of claims.
