Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a medical strand heat setting device. Background Art

[0002] Peripheral nerve injury is the loss of peripheral nerve structure or function due to tumors, trauma and other reasons, which leads to partial or complete loss of sensory, motor and autonomic nerve functions. At present, nerve transection, cutting and small defects are mainly treated by epineurial suture and perineurial suture, and autologous nerve transplantation is also used to treat large peripheral nerve injuries greater than 10 mm.

[0003] However, these treatment methods all have their shortcomings: epineurial suturing and perineurial suturing are difficult to ensure the accurate docking of sensory and motor nerve fibers at the anastomosis site, which in turn affects the effect of surgical repair of nerve damage; and autologous nerve transplantation has disadvantages such as functional loss of the area innervated by the donor nerve, limited sources of donor nerves, and mismatch in size and tissue structure between the donor nerve and the defective nerve to be repaired.

[0004] A large number of studies have shown that the use of tissue engineering methods to construct artificial peripheral nerve sleeves and to repair damaged peripheral nerves can significantly promote peripheral nerve regeneration, quickly restore the function of distal target organs, and reduce the formation of neuromas. Therefore, a peripheral nerve sleeve that better meets the needs of clinical applications is needed, and strands are the main material for making peripheral nerve sleeves, which need to be shaped.

[0005] In the prior art, there are three methods for setting strands of yarn: heat setting, steam setting, water bath setting and sizing setting, all of which have some technical shortcomings: for steam setting and water bath setting, some strands of yarn are hydrophilic materials and are sensitive to water, which may reduce the performance of the product; for steam setting, the strands of yarn must be wound onto a reel and then placed into a steam device. Due to the thickness of the winding, steaming is required for a long time to ensure that the setting effect inside and outside is consistent. A dedicated person is also required to check the steaming water level to prevent the equipment from drying out, resulting in a long time and high cost for steam setting. In addition, the material has excessive water absorption, so it must not only be dried, but the pressure of steaming also makes the strands looser; for sizing setting, a coating must be added to the product and then cleaned off, which is a cumbersome process and the coating composition is unsafe; sizing equipment and heat setting equipment are relatively large and energy-intensive, which has serious limitations on the site and is generally used in the traditional textile industry, and is not suitable for medical materials with smaller products.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] like Figure 1 and Figure 2 As shown in the figure, the present invention discloses a medical strand heat setting device, including a device body 100, a heat setting module 200, a coiling module 300 and a coiling module 400; the device body 100 includes a mounting platform 110 and a setting box 120, the mounting platform 110 is connected to the setting box 120, the heat setting module 200 is placed in the setting box 120, and the coiling module 300 and the coiling module 400 are respectively connected to the mounting platform 110. The coiling module 300 is used to fix the coil of the strand to be set and input the strand to be set to the heat setting module 200, and the strand to be set after twisting is sleeved on the coiling module 300, and the strand is first led to the heat setting module 200 manually or using a wire guide hook; the heat setting module 200 includes a heating component and a positioning column component 220, and the positioning column component 220 is used to lay the strand to be set and make the strand to be set in the same horizontal plane, reducing the space used for heat setting, and can minimize the size of the equipment, but does not hinder the overall heating time and effective length of the strand 900; the heating component with a safe distance relative to the strand to be set can heat the internal space of the setting box 120 to The preset temperature can ensure that the strands 900 are evenly heated during the shaping process, reduce the heat setting time, reduce the hairiness problem caused by steaming, and make the strands 900 of better quality, thereby reducing the frequent fluffing and wire breakage problems during the weaving process, while improving the weaving efficiency and indirectly improving the product quality; the winding module 400 is used to automatically and continuously receive the shaped strands output by the heat setting module 200, and make the wound strands 900 have a certain tension, so that the strands 900 are tightened, avoiding the risk of the strands 900 being loosened and contacting the heating component during the heating and shaping process to burn the strands 900, and the equipment processing process does not require frequent supervision by personnel, which increases employee efficiency. The medical strand heat setting equipment is small in size and low in energy consumption, which greatly improves the shaping efficiency and quality of the strands 900.

[0037] Specifically, the positioning column assembly 220 includes two rows of wire columns 221, each row of wire columns 221 is provided with a plurality of wire columns 221 at intervals, and the two rows of wire columns 221 are staggered and used for staggered winding of the strands to be shaped, and the serpentine winding method is used for routing, which can effectively reduce the size of the equipment and reduce energy consumption. The heating component is arranged between the two rows of wire columns 221, and the heating component is added at the routing position to heat and shape the strands 900. The heated shaped strands can be led out of the shaping box 120 and wound on the winding module 400.

[0038] Exemplarily, a limiting groove is set at the same height on each wire column 221, so that the strand to be formed is placed in the limiting groove and stably in the same horizontal plane. This can effectively ensure that the safety distance between the heating component and the strand to be formed is equal everywhere, thereby protecting the consistency of the forming quality of the strand 900.

[0039] Furthermore, the wire posts 221 are connected to the shaping box 120, and the plurality of wire posts 221 can rotate in the horizontal direction so that the heat shaping module 200 inputs the strand to be shaped and outputs the shaped strand, which can further ensure the stable and uniform input and output of the strand 900, assist the strand 900 in moving, reduce the friction between the strand 900 and the wire posts 221, and avoid the strand 900 from generating hairiness as much as possible. For example, all the wire posts 221 can be set to rotate to minimize negative factors such as friction, or a part of them can be selected to be rotatable, in order to reduce power consumption as much as possible, so as to achieve the effect optimization of high cost performance of the medical strand heat shaping equipment.

[0040] In this embodiment, the positioning column assembly 220 further includes two lead columns 222, which are respectively arranged on the opposite outer sides of the two rows of wire columns 221, and are used to wind the strands to be shaped. The two lead columns 222 are respectively rotated in the horizontal direction so that the heat setting module 200 inputs the strands to be shaped along the same direction and then outputs the shaped strands. The lead columns 222 are respectively arranged between the wire column 221 and the coiling module 300, and between the wire column 221 and the coiling module 400, so as to play the role of transitioning and changing the direction of the strands 900.

[0041] Specifically, the coiling module 300 includes a first rotating shaft 310, which is used to release the wound and rolled strands to be shaped and input them into the heat-setting module 200 to enter the setting box 120; the coiling module 400 includes a second rotating shaft 410 and a motor 420. The first rotating shaft 310 and the second rotating shaft 410 are respectively rotatably arranged on the upper surface of the mounting platform 110, and the motor 420 is arranged on the mounting platform 110. During the heating and setting process of the strands 900, the motor 420 can control the rotation of the second rotating shaft 410 to collect the shaped strands and wind them into an axis, thereby releasing manpower and improving work efficiency.

[0042] In order to further stabilize the tension of the strand 900 wound on the heat setting module 200, a synchronous control module is added to the medical strand heat setting equipment. The synchronous control module is used to monitor and balance the rotation speed of the first rotating shaft 310 and the second rotating shaft 410 so that the rotation frequencies of the two are consistent, the input length and output length of the strand 900 per unit time are the same, and the preset tension when winding the strand 900 can remain stable. Exemplarily, the first rotating shaft member 310 and the second rotating shaft member 410 are both cylinders with the same diameter size, and sprockets are arranged on the outer circumference of the first rotating shaft member 310 and the second rotating shaft member 410. The synchronous control module includes a transmission chain, which can simultaneously wrap around the first rotating shaft member 310 and the second rotating shaft member 410 and engage with the sprockets. When the second rotating shaft member 410 is rotated by the motor 420, the transmission chain drives the first rotating shaft member 310 to rotate at the same amplitude. The angular velocity and linear velocity of the first rotating shaft member 310 and the second rotating shaft member 410 are the same. The first rotating shaft member 310 is assisted by the synchronous control module to make its rotation consistent with the pulling of the strand 900, further avoiding the first rotating shaft member 310 from slipping or getting stuck, which may cause the strand 900 to loosen due to too small tension or break due to too large tension.

[0043] In this embodiment, the heating component specifically includes a plurality of infrared lamp tubes 211, and the plurality of infrared lamp tubes 211 are evenly arranged at a preset distance at the bottom of the shaping box 120 to prevent the strands 900 from being too close to the heating component and being burned. The infrared lamp tubes 211 can maintain the stability of the humidity of the space while heating, and do not involve high-temperature open flames, which is safer and controllable. Exemplarily, the heating component can also be other heat source accessories that can provide high temperature, such as resistance wires, etc., which can dispersedly heat the strands 900 individually and have a lower economic cost. It is necessary to facilitate the staff to control the internal temperature of the shaping box 120 to match the strands 900 of different specifications for heat setting at any time.

[0044] Optionally, the shaping box 120 includes a box body 121 and a box cover 122. The box cover 122 can selectively cover the box body 121 to isolate the heat setting module 200 from the outside world. The shaping box 120 is heat-insulated and sealed, which can quickly heat up and improve the efficiency of heat setting of the strand 900. The box cover 122 can be opened, which can facilitate the staff to adjust the strand 900 in the medical strand heat setting device at any time, making the operation and use of the medical strand heat setting device more convenient. For example, a handle 1222 can be added to the box cover 122 to make it more convenient for the staff to open the shaping box 120.

[0045] In this embodiment, the box cover 122 is provided with an observation window, and a transparent part 1221 is sealed and embedded in the observation window, which can further facilitate the staff to timely observe and monitor the shaping process and status of the strand 900 inside the shaping box 120, thereby improving the safety of the use of the medical strand heat shaping equipment.

[0046] Furthermore, the motor 420 can adjust the speed of the second rotating shaft 410, and a temperature measuring module is added in the shaping box 120. After the strand 900 is put on, the power switch of the heating component is turned on to start the heating component. After the temperature measuring module shows that the temperature in the shaping box 120 rises to the preset temperature, the motor 420 is started and the speed is adjusted to within the process setting range, so that the medical strand heat shaping device starts to automatically heat and wind, and the time and speed of starting winding are recorded. The strand 900 in the shaping box 120 is confirmed through the observation window. 0's transmission is normal. If it is normal, process it according to the set temperature requirements, speed requirements and time: after a period of processing, turn off the motor 420 and the heating power switch, use scissors to cut the shaped strands of the output shaping box 120, and the total length of the shaped strand reel on the winding module 400 can be calculated as: the actual strand transmission time multiplied by the strand transmission speed is the total winding length of the shaped strand reel. If it is still necessary to shape the twisted strands again to obtain the shaped strand reel, repeat the above steps.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
