Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing, specifically to a needle tip processing device and method for puncture and injection needles, and particularly to a needle tip processing device and method for micromanipulation puncture and injection needles. Background Technology

[0002] Currently, the production of puncture injection needles in China requires four processes: breaking, grinding, pulling, and bending. The needle manufacturing equipment currently used in China separates these four processes, which increases manual time and makes it difficult to control the precision. Furthermore, traditional equipment relies on visual inspection to judge the needle tip manufacturing process, making it difficult to guarantee the success rate of the needle tip (or needle blank).

[0003] Patent document CN209407278U discloses an automatic bending angle shaping processing device for epidural anesthesia puncture injection needles, including a clamping mechanism, a reciprocating motion power mechanism, and a grooved wheel mechanism. The grooved wheel mechanism includes a frame, a lower grooved wheel, an upper grooved wheel, a frame for mounting the upper grooved wheel, and a power component for enabling the upper grooved wheel to move up and down. Multiple corresponding grooves are provided on the upper and lower grooved wheels. The lower grooved wheel is connected to the reciprocating motion power mechanism via a spherical bearing. The power mechanism drives a swing component to move, which in turn causes the lower grooved wheel to swing. The clamping mechanism is used to hold the puncture injection needle in place, preventing displacement and deflection. However, this solution only covers the bending process in the puncture injection needle manufacturing process. Other processes in the puncture injection needle manufacturing process are still performed separately from the bending process, and manual adjustment of the needle tip position and angle is required in each process. This still results in low manufacturing efficiency and wasted manpower. Summary of the Invention

[0062] Detailed Implementation

[0063] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0064] The injection needle is an indispensable tool in the field of assisted reproduction, specifically in in vitro fertilization (IVF) procedures such as ICSI (Intracytoplasmic Sperm Injection).

[0065] This invention provides a device for processing the tip of an injection needle, such as... Figure 1-3 As shown, it includes a clamping mechanism 1, a processing mechanism 2, and a monitoring and operating mechanism;

[0066] The clamping mechanism 1 is used to clamp the needle tip 100 and drive the needle tip 100 to move between a first position and a second position;

[0067] like Figures 4-5 As shown, the processing mechanism 2 is equipped with a grinding needle assembly 21, a needle pulling assembly 22, a needle breaking assembly 23, a bending assembly 24, and a processing electric rotary slide 25; preferably, the processing electric rotary slide 25 is a high-precision electric rotary slide.

[0068] The grinding needle assembly 21, the needle removal assembly 22, the needle breakage assembly 23, and the bending assembly 24 are all mounted on the machining electric rotary slide 25, and the grinding needle assembly 21, the needle removal assembly 22, the needle breakage assembly 23, and the bending assembly 24 are distributed along the circumference of the machining electric rotary slide 25; the machining electric rotary slide 25 can drive the grinding needle assembly 21, the needle removal assembly 22, the needle breakage assembly 23, and the bending assembly 24 to rotate to the third position respectively;

[0069] The second position corresponds to the third position;

[0070] When the needle tip 100 is in the second position and the needle grinding assembly 21 is in the third position, the puncture injection needle tip processing equipment is in a needle grinding state; the needle grinding assembly 21 performs a needle grinding operation on the needle tip 100 (or needle blank); when the needle tip 100 is in the second position and the needle removal assembly 22 is in the third position, the puncture injection needle tip processing equipment is in a needle removal state; the needle removal assembly 22 performs a needle removal operation on the needle tip 100; when the needle tip 100 is in the second position and the needle breaking assembly 23 is in the third position, the puncture injection needle tip processing equipment is in a needle breaking state; the needle breaking assembly 23 performs a needle breaking operation on the needle tip 100; when the needle tip 100 is in the second position and the bending assembly 24 is in the third position, the puncture injection needle tip processing equipment is in a bending state; the bending assembly 24 performs a bending operation on the needle tip 100. The first position is the position where the needle tip 100 is furthest away from the processing mechanism 2, and the second position is the position where the needle tip 100 is processed by the processing mechanism 2.

[0071] The needle grinding assembly 21 includes a needle grinding station 211 and a needle grinding component. When the puncture injection needle tip processing equipment is in the needle grinding state, the needle tip 100 is located on the needle grinding station 211, and the needle grinding component interacts with the needle tip 100 to realize the needle grinding operation. The needle removal assembly 22 includes a needle removal station 221 and a needle removal component. When the puncture injection needle tip processing equipment is in the needle removal state, the needle tip 100 is located on the needle removal station 221, and the needle removal component interacts with the needle tip 100 to realize the needle removal operation. The needle breaking assembly 23 includes a needle breaking station 231 and a needle breaking component. When the puncture injection needle tip processing equipment is in the needle breaking state, the needle tip 100 is located on the needle breaking station 231, and the needle breaking component interacts with the needle tip 100 to realize the needle breaking operation. The bending assembly 24 includes a bending station 241 and a bending component. When the puncture injection needle tip processing equipment is in a bent state, the needle tip 100 is located on the bending station 241, and the bending component interacts with the needle tip 100 to achieve the bending operation. The grinding component performs surface grinding on the needle tip, grinding the needle tip into an arc-shaped bevel at a different angle. In a preferred embodiment, the grinding component includes a grinding motor, a grinding disc, and a grinding disc. The grinding disc is a circular grinding disc, mounted on the rotating shaft of the grinding motor. The grinding disc is attached to the surface of the grinding disc. The needle tip is placed at the corresponding position on the surface of the grinding disc, and the grinding operation is achieved by rotating the motor to drive the grinding disc to rotate. The principle is as follows: the grinding motor drives the grinding disc, and the needle tip is placed statically at the corresponding position on the surface of the grinding disc. The grinding disc rotates to grind the needle tip into an angled bevel. In addition, the grinding component can also be implemented using existing grinding needle structures in the prior art.

[0072] The needle removal operation involves pulling out the sharpened needle tip from the originally curved beveled surface of the ground needle. In a preferred embodiment, the needle removal operation can be achieved as follows: the curved tip of the ground needle tip is heated by a glass bead, and the curved tip of the ground needle tip comes into instantaneous contact with the surface of the heated glass bead. The principle and structure of the needle removal operation are as follows: a V-shaped platinum wire is connected between the cross-sections of two copper parts to form a resistance wire. A circular glass bead larger than the outer diameter of the needle tip is made at the top of the V-shaped platinum wire. The curved beveled needle tip is placed at the corresponding position at the front end of the glass bead. By instantaneously heating the glass bead, it will move forward a certain distance due to thermal expansion and contraction, and then retract, thus removing the sharpened needle tip from the curved beveled surface. Alternatively, the needle removal operation can also be achieved using existing needle removal structures.

[0073] The needle breaking operation is the process of causing the needle tip to break at a corresponding position. In a preferred embodiment, this can be achieved by utilizing the principle of thermal expansion and contraction to break the needle tip at the corresponding position, forming a needle tip with a clean break. The principle and structure of the needle breaking operation are as follows: A V-shaped platinum wire is connected to the cross-section between two copper parts to form a resistance wire. A circular glass bead larger than the outer diameter of the needle tip is made at the center of the lower edge of the V-shaped platinum wire. The needle blank is placed at the position where the lower edge of the glass bead is tangent to the bead. By instantaneously heating it with electricity, the glass bead is instantly heated and melts into the needle blank. At the same time as the power is instantly cut off, the glass bead cools and retracts, pulling the needle blank apart and forming a needle tip with a clean break. In addition, the needle breaking operation can also be achieved using existing needle breaking structures in the prior art.

[0074] The bending operation involves bending the needle tip to form needle tips at different angles. In a preferred embodiment, this can be achieved by slowly softening and bending the needle tip to different angles through prolonged heating of a glass bead. The principle and structure of the bending operation are as follows: A V-shaped platinum wire is connected vertically between two copper parts to form a resistance wire. A circular glass bead larger than the outer diameter of the needle tip is made at the vertical center of the top of the V-shaped platinum wire. The bent needle blank is placed stationary below the glass bead. By continuously heating it with electricity, the glass bead is kept continuously energized. The needle blank is slowly moved closer to the glass bead. When the needle blank softens and bends to the specified angle, the power to the platinum wire is turned off, resulting in a needle tip with the desired bending angle. Alternatively, the bending operation can also be achieved using existing bending structures in the prior art.

[0075] The monitoring and operation mechanism includes an electron microscope 31 and a display 32; the lens portion of the electron microscope 31 is aligned to a third position; the electron microscope 31 and the display 32 are electrically connected. The monitoring and operation mechanism also includes a controller and an operating table 33; the operating table 33, the electron microscope 31, and the display 32 are all electrically connected to the controller. Preferably, the electron microscope 31 is a high-precision microscope.

[0076] like Figure 6-10 As shown, the clamping mechanism 1 includes a needle holder 10, a three-axis electric moving structure 16, and a first rotating slide 17;

[0077] like Figure 6 As shown, the needle holder 10 includes a drive motor 11, a needle blank pressing block 12, a needle blank mounting block 13, a bracket 14, a ventilation assembly 15, and a needle blank rotation assembly;

[0078] The drive motor 11, the ventilation assembly, and the needle blank pressing block 12 are all mounted on the bracket 14; the needle blank mounting block 13 is provided with a groove structure, and the needle tip 100, or needle tip, is placed on the groove structure; the drive motor 11 is connected to the needle blank pressing block 12 and can drive the needle blank pressing block 12 to press the needle tip 100 firmly on the groove structure; the ventilation assembly includes a receiving chamber 151 and a ventilation pipe 152; the end of the needle tip 100 is located in the receiving chamber 151, and the end of the ventilation pipe 152 is located in the receiving chamber 151, and the ventilation pipe 152 is used to introduce gas; in a preferred embodiment, the groove structure is a V-shaped groove structure, the first rotary slide 17 is a high-precision rotary slide, and the drive motor 11 is a micro motor.

[0079] like Figure 7 As shown, the needle holder 10 is mounted on the three-axis electrically driven moving structure 16 via a first rotating slide 17. The first rotating slide 17 can drive the needle holder 10 to rotate along the axis of the first rotating slide 17, which is defined as the R-axis, meaning the first rotating slide 17 can drive the needle holder 10 to rotate along the R-axis. The three-axis electrically driven moving structure 16 can drive the first rotating slide 17, thereby moving the needle holder 10 along the X-axis, Y-axis, and Z-axis; the X-axis, Y-axis, and Z-axis are perpendicular to each other. In a preferred embodiment, the needle holder 10 is provided with a slide connection position 101, and the needle holder 10 is connected to the first rotating slide 17 through the slide connection position 101.

[0080] like Figure 6 As shown, in a preferred embodiment, the needle blank rotating assembly includes a rotating disk 161 and a needle blank rotating motor; the rotating disk 161 is installed at one end of the receiving chamber 151, and the needle tip 100 passes through the rotating disk 161; the needle blank rotating motor can drive the rotating disk 161 to rotate, thereby causing the needle tip 100 to rotate along the axis of the rotating disk 161. The axis of the rotating disk 161 is defined as the O-axis, that is, the needle blank can rotate along the O-axis under the drive of the rotating disk 161.

[0081] In a preferred embodiment, the O-axis and the R-axis are perpendicular to each other.

[0082] The working principle of the three-axis electric moving structure 16 is to utilize the combination of three sets of linear sliding components to achieve precise linear motion of the needle holder 10, which is fixed to the three-axis electric moving structure 16 via the first rotary slide 17, on the X, Y, and Z axes, ensuring accurate positioning and processing of the needle blank (or needle tip). The three-axis electric moving structure 16 includes an X-axis sliding component, a Y-axis sliding component, and a Z-axis sliding component.

[0083] like Figure 7-10 As shown, the needle holder 10 is mounted on the first rotary slide 17, the first rotary slide 17 is mounted on the Z-axis sliding assembly, the Z-axis sliding assembly is mounted on the Y-axis sliding assembly, and the Y-axis sliding assembly is mounted on the X-axis sliding assembly. The Z-axis sliding assembly includes a Z-axis motorized slide 164; the Y-axis sliding assembly includes a Y-axis motorized slide 163; and the X-axis sliding assembly includes an X-axis motorized slide 162.

[0084] Preferably, the X-axis electric slide 162 includes an X-axis slider, an X-axis guide rail, and an X-axis drive motor; the Y-axis sliding assembly is mounted on the X-axis slider; the X-axis drive motor drives the X-axis slider to move on the X-axis guide rail via any of the following structures: a screw and nut structure; a gear and rack structure; or a push rod structure. The Y-axis electric slide 163 includes a Y-axis slider, a Y-axis guide rail, and a Y-axis drive motor; the Z-axis sliding assembly is mounted on the Y-axis slider; the Y-axis drive motor drives the Y-axis slider to move on the Y-axis guide rail via any of the following structures: a screw and nut structure; a gear and rack structure; or a push rod structure. The Z-axis electric slide 164 includes a Z-axis slider, a Z-axis guide rail, and a Z-axis drive motor; the first rotary slide 17 is mounted on the Z-axis slider; the Z-axis drive motor drives the Z-axis slider to move on the Z-axis guide rail via any of the following structures: a screw and nut structure; a gear and rack structure; or a push rod structure.

[0085] In a preferred embodiment, the three-axis electric moving structure 16, the first rotary slide 17, and the drive motor 11 are all electrically connected to the controller. In an embodiment where a needle blank rotary motor is provided, the needle blank rotary motor is also electrically connected to the controller.

[0086] The working principle of the first rotary slide 17 is to control the rotation of the needle holder 10 by using the precision rotation of the slide. For example, during processing, by adjusting the angle of the needle holder 10, the angle of the needle blank is adjusted, so that the grinding angle is adjusted more precisely, ensuring that the bevel does not change when grinding the needle tip. After the grinding is completed, it can drive the needle holder 10 to automatically rotate back to the initial setting.

[0087] The clamping mechanism 1 mainly utilizes three high-precision electric linear slide groups, one high-precision electric rotary slide, and one needle blank rotation assembly to achieve the requirement of moving in different directions while ensuring accuracy during needle tip depth processing. The high-precision electric linear slide groups and high-precision electric rotary slide are the primary components, while the needle blank rotation assembly is secondary. The clamping mechanism 1 solves the technical problem of needing to move in five directions (X, Y, Z, R, O) and requiring positive pressure ventilation during needle tip processing. This invention mainly utilizes the cooperation between the X-axis electric slide 162, Y-axis electric slide 163, Z-axis electric slide 164, the first rotary slide 17, and the needle blank rotation assembly to achieve movement in these five directions. Furthermore, the clamping mechanism 1 can also ensure the cleanliness of the needle tip's inner wall by introducing positive pressure gas during needle tip processing sequence switching through the ventilation assembly 15, allowing the entire needle tip processing process to be completed without removing the needle blank.

[0088] The working principle and process of this invention are as follows:

[0089] After the needle blank is processed in one process, the needle blank and processing position will automatically switch to the next process under the action of the rotary slide and linear slide group, and so on to complete all processes of the needle tip. Specifically, the operator installs the drawn needle tip 100 on the clamping mechanism 1. At this time, the needle tip 100 is located in the first position. After the puncture injection needle tip processing equipment is turned on, the drive motor 11 first drives the needle blank pressing block 12 to press the needle tip 100 on the groove structure. Then, the controller controls the puncture injection needle tip processing equipment to enter the needle breakage state, needle grinding state, needle pulling state, and bending state in sequence according to the preset parameters to complete the entire manufacturing process of the puncture injection needle. Finally, the needle blank pressing block 12 is raised, and the operator replaces another drawn needle tip 100 to continue processing. It is worth noting that each time a switch between different states is performed, the clamping mechanism 1 will control the needle tip 100 to return to the first position, and then the machining electric rotary slide 25 will rotate to rotate the next corresponding work station to the third position. Finally, the clamping mechanism 1 will control the needle tip 100 to move to the second position, so that the corresponding working part interacts with the needle tip 100 through the corresponding work station to realize the corresponding needle blank machining operation.

[0090] The electron microscope 31 allows the operator to monitor the processing at any time. The electron microscope 31 displays images on a monitor. In a preferred embodiment, the electron microscope 31 automatically adjusts the magnification according to different needle tip processing procedures under preset parameters. If a processing failure or deviation occurs, the operator can also manually control the puncture injection needle tip processing equipment to process the needle blank through the control panel 33.

[0091] This invention utilizes the precision rotation of an electric rotary slide 25 to control the positions of the four processing stations for needle tip processing and to ensure the processing angle of the needle tip, thus guaranteeing accurate processing after automatic focusing of the needle tip. The focusing is achieved by controlling the movement of the clamping needle tip 100 to the second position via the clamping mechanism 1, and then rotating the corresponding station to the third position via the processing mechanism 2.

[0092] The manufacturing process of puncture injection needles involves four steps: breaking, grinding, pulling, and bending. Traditional manufacturing processes require these four steps to be performed on different equipment. However, this invention, through the design of a clamping mechanism 1, a processing mechanism 2, and a monitoring and operating mechanism, achieves a one-time process from needle blank to finished needle through the combination of these multiple mechanisms, eliminating the need to remove the needle blank during the process. This solves the problem of manually changing the needle blank, thus avoiding the tedious steps of manually changing processing positions during needle blank processing, achieving a one-time completion effect. The advantages of this invention are that it can automatically complete the free switching between the needle blank and the processing position, solving the problem of manually controlling the depth of needle tip precision during processing. Under the guidance of a microscope, the success rate of needle tip processing is greatly improved, thereby increasing the production efficiency and success rate of puncture injection needles.

[0093] The present invention also provides a method for processing the tip of a puncture injection needle, which, using the aforementioned puncture injection needle tip processing equipment, further includes the following steps.

[0094] S1. The operator installs the drawn needle tip 100 onto the clamping mechanism 1, at which point the needle tip 100 is located in the first position;

[0095] S2. After the puncture injection needle tip processing equipment is turned on, the drive motor 11 first drives the needle blank pressing block 12 to press the needle tip 100 on the groove structure. Then, the controller controls the puncture injection needle tip processing equipment to enter the needle breakage state, needle grinding state, needle pulling state, and bending state in sequence according to the preset parameters to complete the entire manufacturing process of the puncture injection needle.

[0096] S3. Finally, the needle blank pressing block 12 is lifted, and the operator replaces it with another drawn needle tip (100). The puncture injection needle tip processing equipment continues to process it.

[0097] In step S2, each time a switch between different states is performed, the clamping mechanism 1 will control the needle tip 100 to return to the first position, and then the machining electric rotary slide 25 will rotate to rotate the next corresponding workstation to the third position. Finally, the clamping mechanism 1 will control the needle tip 100 to move to the second position, so that the corresponding working part interacts with the needle tip 100 through the corresponding workstation to realize the corresponding needle blank processing operation.
