Description
Technical Field
[0001] This utility model belongs to the technical field of medical device storage equipment, specifically relating to a protective box for a puncture needle instrument. Background Technology
[0002] A puncture needle is a medical device used in minimally invasive surgery to sample and inject tissues from various organs, including the kidneys, liver, lungs, breasts, thyroid gland, prostate, pancreas, testes, uterus, ovaries, and body surface.
[0003] According to standards, puncture needles are classified into different specifications and models based on the outer diameter of the needle tube, ranging from 0.6mm to 2.0mm. Further, they are categorized by the number of uses into disposable and reusable puncture needles. Reusable puncture needles require sterilization before and after use and are encased in a sharps protector to facilitate transport and handling before use while maintaining the needle's sterility. Currently, the protective cover used consists of only a single tubular sleeve, requiring careful handling during assembly and posing a risk of accidental needle tip injury during use. Furthermore, sterilizing puncture needles requires handling them one by one, which is time-consuming. Utility Model Content
[0004] To address the aforementioned issues, improve the efficiency of sterilization and transport of puncture needles, and facilitate storage and retrieval while reducing the risk of accidental injury during handling, this invention proposes a protective case for puncture needle instruments. The needle tube portion of the puncture needle is encased in a cannula and its tapered opening. The needle hub portion is then secured using a movable locking block and a semi-circular ring on the needle holder, thus fixing the entire puncture needle within the case for easy storage and transport. Furthermore, multiple puncture needles can be simultaneously removed for sterilization.
[0005] To achieve the technical objectives mentioned above, this utility model is implemented through the following technical solution: a protective case for a puncture needle instrument, comprising a case body;
[0006] A fixed cover is installed on the upper front of the box body, which closes the front half of the box body. A straight sliding groove is symmetrically opened on both sides of the upper rear of the inner side of the box body. A movable cover is installed in the straight sliding groove, which controls the closing and opening of the rear half of the box body.
[0007] The rear end of the box is symmetrically provided with parallel slots on both sides. A horizontal needle holder is installed in the two parallel slots. Several semi-circular rings are installed on the needle holder. The diameter of the semi-circular rings is larger than the needle holder diameter of the largest specification of the standard puncture needle. Vertical through slots are provided on the needle holder on both sides of the semi-circular rings. Movable blocks are installed in the through slots.
[0008] A fixed shaft is installed at the front end of the box body parallel to the needle holder. The fixed shaft is fitted with the same number of rotating sleeves as the semicircular rings. The rear end axis of each rotating sleeve coincides with the axis of the semicircular ring and is fitted with a sleeve. Each sleeve can rotate independently on the fixed shaft with the rotating sleeve.
[0009] Furthermore, the movable locking block is connected to the inner side of the through groove via a first spring. The spring, in conjunction with the movable locking block, can clamp and fix the needle seat of the puncture needle. After receiving sufficient external force, the movable locking block can be pressed into the through groove to remove the needle seat of the puncture needle.
[0010] Furthermore, the needle holder is equipped with a loop rod at both ends of its outer side. The loop rod can pull the needle holder out of the parallel slot, thereby removing multiple puncture needles fixed on the needle holder from the box at the same time.
[0011] Furthermore, a rotating cover is hinged to the upper rear end of the box body. The rotating cover can close the front end of the box body and restrict the loop rod in the parallel slot. When it is necessary to remove the loop rod, the loop rod can be moved out by rotating the rotating cover upwards.
[0012] Furthermore, the inner diameter of the cannula is larger than the maximum diameter of the standard puncture needle tube. A conical opening made of silicone material is installed on the end of the cannula near the needle seat frame. The conical opening facilitates the insertion of the needle tube into the cannula and surrounds and adheres to the connection between the needle seat and the needle tube through its own deformation, adapting to different specifications of puncture needles and fixing the needle seat by its own elasticity.
[0013] Furthermore, a second spring is installed inside the connection between the rotating sleeve and the sleeve. One end of the second spring is connected to the sleeve, and the other end is connected to the rotating sleeve. The second spring allows the sleeve to extend and retract freely inside the rotating sleeve, which is convenient to adapt to different specifications and models of puncture needles and prevents the needle seat from being unable to be fixed due to excessive length at the connection between the needle seat and the needle tube.
[0014] Furthermore, the inner sides of the box are symmetrically provided with inclined grooves that are higher at the front end and lower at the rear end near the needle holder. A movable cylinder parallel to the needle holder is installed in the inclined groove. When the movable cylinder moves upward along the inclined groove, all the sleeves can be lifted upward, so that the puncture needle fixed in the semi-circular ring can be disengaged from the movable locking block.
[0015] Furthermore, symmetrical positioning blocks are installed on the inner side of the connection between the needle holder and the loop rod. The positioning blocks can prevent the needle holder from shifting position during the process of putting it back after the loop rod and the needle holder are pulled out.
[0016] The beneficial effects of this utility model are:
[0017] 1. This utility model can set up the needle tube of the puncture needle and fix both the needle tube and the needle seat in the box. The needle tube set of the puncture needle is protected by the movable sleeve and the conical mouth of the silicone material. At the same time, the needle seat of the puncture needle is fixed by the semi-circular ring and the movable locking block on the needle seat frame. With the cooperation of the second spring and the sleeve, it can adapt to various specifications of puncture needles and realize the fixed storage of the entire puncture needle.
[0018] 2. By rotating the rotating cover upwards, the paperclip can be pulled out, which moves the needle holder and all the puncture needles fixed on the needle holder out at the same time, making it easier to disinfect the puncture needles and improving the processing speed of medical staff;
[0019] 3. By moving the movable cylinder upwards, the needle holders of all puncture needles can be removed from the needle holder frame, making them easy to pull out during use, improving retrieval efficiency, and preventing accidental injury when removing the tube sleeve.

Detailed Implementation
[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.
[0030] Example 1
[0031] See Figures 1 to 6 As shown, and based on the contents of this specification, a protective case for a puncture needle instrument is provided, including a case body 1;
[0032] A fixed cover 2 is installed on the upper front of the box body 1, which closes the front half of the box body 1. A straight sliding groove 101 is symmetrically opened on both sides of the upper rear of the inner side of the box body 1. A movable cover 3 is installed in the straight sliding groove 101. The movable cover 3 controls the closing and opening of the rear half of the box body 1. A rotating cover 11 is hinged to the upper rear of the box body 1. The rotating cover 11 can close the front end of the box body 1.
[0033] The rear ends of the box 1 are symmetrically provided with parallel slots 103. A transverse needle holder 4 is installed in each of the two parallel slots 103. A loop rod 403 is installed at both ends of the outer side of the needle holder 4. The loop rod 403 can pull the needle holder 4 out of the parallel slots 103. When the loop rod 403 needs to be removed, rotating the rotating cover 11 upwards will allow multiple puncture needles fixed on the needle holder 4 to be removed simultaneously from the box 1. The needle holder 4 is equipped with four semicircular rings 401. The diameter of the semicircular rings 401 is larger than the maximum needle holder diameter of a standard puncture needle. The needles on both sides of the semicircular rings 401... The seat frame 4 has a vertical through groove 402. A movable locking block 5 is installed in the through groove 402. The movable locking block 5 is connected to the inside of the through groove 402 by a first spring 6. The needle seat of the puncture needle can be clamped and fixed by the spring and the movable locking block 5. After receiving sufficient external force, the movable locking block 5 can be squeezed into the through groove 402 to remove the needle seat of the puncture needle. A positioning block 404 is symmetrically installed on the inside of the connection between the needle seat frame 4 and the ring rod 403. The positioning block 404 can prevent the position of the needle seat frame 4 from shifting during the process of putting it back after the ring rod 403 and the needle seat frame 4 are pulled out.
[0034] A fixed shaft 7 is mounted parallel to the needle holder 4 at the front end of the housing 1. Rotating sleeves 8, the same number as the semicircular rings 401, are fitted onto the fixed shaft 7. The rear axis of each rotating sleeve 8 coincides with the axis of the semicircular ring 401 and is fitted with a sleeve 9. Each sleeve 9 can rotate independently on the fixed shaft 7 along with the rotating sleeve 8. The inner diameter of the sleeve 9 is larger than the maximum diameter of a standard puncture needle tube. A silicone conical opening 901 is installed on the end of the sleeve 9 near the needle holder 4, facilitating needle insertion. The cannula 9 surrounds and adheres to the connection between the needle hub and the needle tube through its own deformation, adapting to different specifications of puncture needles. It uses its own elasticity to fix the needle hub. A second spring 12 is installed inside the connection between the rotating sleeve 8 and the cannula 9. One end of the second spring 12 is connected to the cannula 9, and the other end is connected to the rotating sleeve 8. The second spring 12 allows the cannula 9 to freely extend and retract within the rotating sleeve 8, which is convenient for adapting to different specifications of puncture needles and prevents the needle hub from being unable to be fixed due to excessive length at the connection between the needle hub and the needle tube.
[0035] The inside of the box 1 has symmetrically arranged inclined grooves 102 with a higher front end and a lower rear end near the needle holder 4 on both sides. A movable cylinder 10 parallel to the needle holder 4 is installed in the inclined groove 102. When the movable cylinder 10 moves upward along the inclined groove 102, all the sleeves 9 can be lifted upward, so that the puncture needles fixed in the semi-circular ring 401 can be disengaged from the moving block 5, making it convenient to take out each puncture needle.
[0036] When using this device, first turn the control column 301 to open the movable cover 3, then lift the movable cylinder 10 upwards. At this time, all the sleeves 9 are lifted by the movable column. Then, insert the needle tube of the puncture needle that needs to be protected into the sleeve along the conical opening 901, and fix the conical opening 901 and the needle seat together. Then, adjust the extension and retraction length of the sleeve in the rotating sleeve 8 according to the length of the puncture needle seat. Align the needle seat with the movable locking block 5 on the semi-circular ring 401. After pressing down, the movable locking block 5 moves under the action of external force, and the puncture needle seat is locked in the semi-circular ring 401 and the movable locking block 5. Then close the movable cover 3. When it is necessary to remove the puncture needle, open the movable cover 3, lift the needle hub of the puncture needle upward out of the semicircular ring 401, and then pull it out. If multiple puncture needles are needed, pull the movable cylinder 10 upward to disengage the needle hubs of all puncture needles from the semicircular ring 401. When it is necessary to remove all puncture needles at the same time for disinfection, first rotate the rotating cover 11 upward to open it, then pull the loop rod 403 to move the needle hub frame 4 out along the parallel slot 103. At this time, the needle hub of the puncture needle is engaged on the needle hub frame 4 and moves with it, and the needle tube is disengaged from the needle tube sleeve, so that all puncture needles can be removed at the same time.
