Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a puncture needle assembly machine capable of efficient assembly. Background Art

[0002] Puncture needles are commonly used medical devices, which can be used to puncture organs, tissues or inject drugs. Puncture needles are divided into ozone puncture needles, Hakko puncture needles, reusable puncture needles, puncture needles with side holes, medical device puncture needles, etc.

[0003] For example, a puncture needle assembly machine capable of efficient assembly with the patent number CN213888954U includes a bottom plate. The upper end of the bottom plate is fixedly connected with a placement plate. A chute is opened on the upper surface of the placement plate. An auxiliary block is fixedly connected to the right side of the placement plate. However, the above document still has deficiencies. When in use, when the tip and core end of the pleural biopsy needle fall to the bottom of the chute through the inside of the chute, the tip and core end of the pleural biopsy needle contact the upper surface of the contact plate. Such a method only needs to limit the sliding position of the tip and core, so that the fixed position of the tip and core remains unchanged. However, in the above document, the pleural biopsy needle is placed inside the placement plate, and the pleural biopsy needle moves by relying on the inclination angle of the inclined groove inside the placement plate. However, the inclination angle of the groove inside the placement plate is fixed. When the pleural biopsy needle is placed in the groove inside the placement plate, the pleural biopsy needle may not move due to the friction between the pleural biopsy needle and the placement plate, and thus efficient assembly cannot be achieved. At the same time, in the above document, after the pleural biopsy needle is assembled, the pleural biopsy needle is discharged by moving the contact plate. During the movement of the moving plate, the lower end of the pleural biopsy needle will move along with the moving plate to a certain extent, generating a force in the inclined direction of the pleural biopsy needle, and the pleural biopsy needle is prone to damage when being discharged after being assembled. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the pleural biopsy needle may not move due to the friction between the pleural biopsy needle and the placement plate, and to provide a puncture needle assembly machine capable of efficient assembly.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a puncture needle assembly machine capable of efficient assembly, including a frame and a first support plate. Two first support plates are fixedly connected to the outer wall of the frame. A rotating mechanism is arranged above the frame.

The ends of the two connecting rods are both fixedly connected to a second support plate. The outer wall of the second support plate is slidably connected to the frame. A discharging mechanism is arranged below the second support plate.

[0007] Preferably, the rotating mechanism includes a bracket fixedly connected to the upper surface of the frame. Both outer walls of the two ends of the bracket are rotatably connected to the worm through bearings. A runner is fixedly connected to the end of the worm. The worm is meshed with a semi-worm gear. A placement plate is fixedly connected above the semi-worm gear. Two semi-cylinders are fixedly connected below the placement plate. The outer walls of the semi-cylinders are slidably connected to the bracket. The two semi-cylinders are respectively fixedly connected to the front and rear surfaces of the semi-worm gear.

[0008] Preferably, the discharging mechanism includes a first electric push rod rotatably connected to a second support plate through a pin shaft. The output end of the first electric push rod is rotatably connected to a support rod through a pin shaft. A third support plate is fixedly connected to the end of the support rod. The third support plate is rotatably connected to the second support plate through a pin shaft. A plug block is fixedly connected to the upper surface of the third support plate. The outer wall of the plug block is in clearance fit with a through hole provided in the second support plate.

[0009] Preferably, two first vertical plates are fixedly connected to the upper surface of the second support plate. A second electric push rod is fixedly connected to the inner side of the first vertical plate. A clamping block is fixedly connected to the output end of the second electric push rod.

[0010] Preferably, the frame is fixedly connected to the outer wall of a cylinder. A second vertical plate is fixedly connected to the outer wall of the cylinder.

[0011] A puncture needle assembling machine capable of efficient assembly proposed by the present utility model has the beneficial effects that: through the cooperation among the bracket, the worm, the runner, the semi-worm gear, the placement plate and the semi-cylinders, place the pleural biopsy needle in the groove provided inside the placement plate.

Rotate the runner, the runner drives the worm to rotate, the worm drives the semi-worm gear to rotate, the semi-worm gear drives the placement plate to rotate, the placement plate drives the semi-cylinders to rotate, and the semi-cylinders slide inside the bracket to play a role in supporting and guiding the movement of the placement plate. Stop rotating the runner when the placement plate rotates clockwise to an angle at which the pleural biopsy needle can slide, avoiding the situation that the pleural biopsy needle may not move due to friction with the placement plate, thereby enabling efficient assembly.

[0012] Through the cooperation among the first electric push rod, the support rod, the third support plate and the plug block, the first electric push rod drives the support rod to move, the support rod drives the third support plate to move. The third support plate rotates during the movement, the third support plate drives the plug block to move, and the plug block separates from the through hole provided in the second support plate.

The worm 302 drives the semi-worm gear 304 to rotate;

[0024] Above the semi-worm gear 304, a placement plate 305 is fixedly connected. The semi-worm gear 304 drives the placement plate 305 to move. An inclined groove is arranged inside the placement plate 305. Two semi-cylinders 306 are fixedly connected below the placement plate 305.

The third support plate 403 drives the plug 404 to move. The plug 404 separates from the through hole provided in the second support plate 7. The assembled pleural biopsy needle falls from the through hole provided in the second support plate 7, realizing the discharge of the assembled pleural biopsy needle. When the plug 404 moves, the pleural biopsy needle will not be subjected to forces in the left and right directions, and the pleural biopsy needle is not easily damaged when it is discharged after being assembled.

[0028] Working principle:

[0029] When using a puncture needle assembling machine capable of efficient assembly to assemble a pleural biopsy needle;

[0030] Tilt angle adjustment stage of the placement plate:

[0031] Place the pleural biopsy needle in the groove provided inside the placement plate 305. If the pleural biopsy needle does not slide inside the placement plate 305, adjust the tilt angle of the placement plate 305. Rotate the runner 303. The runner 303 drives the worm 302 to rotate. The worm 302 drives the half worm gear 304 to rotate. The half worm gear 304 drives the placement plate 305 to rotate. The placement plate 305 drives the semi-cylinder 306 to rotate. The semi-cylinder 306 slides inside the bracket 301 to support and guide the movement of the placement plate 305. The placement plate 305 rotates clockwise to the angle at which the pleural biopsy needle can slide and then stops rotating the runner 303, avoiding the situation where the pleural biopsy needle may not move due to friction with the placement plate, thereby enabling efficient assembly.

[0032] Pleural biopsy needle assembly stage:

[0033] The pleural biopsy needle enters the interior of the cylinder 11. The second vertical plate 12 prevents the pleural biopsy needle from moving outside the cylinder 11. The tip and core end of the pleural biopsy needle fall into the interior of the cylinder 11 and contact the plug 404. Since the cylinder 11 is vertical, the tip and core end of the pleural biopsy needle vertically drops into the interior of the cylinder 11. The size of the opening in the cylinder 11 just matches the tip and core end of the pleural biopsy needle. The second electric push rod 9 drives the clamping blocks 10 to move, and the two clamping blocks 10 position the pleural biopsy needle in contact with the plug 404. The cylinder 5 drives the connecting rod 6 to move, and the connecting rod 6 drives the second support plate 7 to slide, thereby controlling the height position of the tip and core end of the pleural biopsy needle. Thus, when the flat core and the tip of the pleural biopsy needle are combined, the depth of the flat core of the pleural biopsy needle entering the tip and core end of the pleural biopsy needle is controlled. Then, the assembly is carried out according to the required length of the pleural biopsy needle. Continue to place the pleural biopsy needle into the groove inside the placement plate 305, and the pleural biopsy needle falls into the interior of the cylinder 11. The flat core of the pleural biopsy needle is pushed against the tip and core end of the pleural biopsy needle, thereby completing the combination work of the pleural biopsy needle;

[0034] Discharging stage of the assembled pleural biopsy needle:

[0035] The second electric push rod 9 drives the clamping blocks 10 to move in the reverse direction and separate from the pleural biopsy needle. The first electric push rod 401 is started, and the first electric push rod 401 drives the support rod 402 to move. The support rod 402 drives the third support plate 403 to move. The third support plate 403 rotates during movement, and the third support plate 403 drives the plug 404 to move. The plug 404 separates from the through hole provided in the second support plate 7. The assembled pleural biopsy needle falls from the through hole provided in the second support plate 7, realizing the discharge of the assembled pleural biopsy needle. When the plug 404 moves, the pleural biopsy needle will not be subjected to forces in the left and right directions, and the pleural biopsy needle is not easily damaged when it is discharged after the combination is completed.
