Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical consumables collection devices, and in particular to the collection of surgical needles during and after microsurgical procedures, specifically to a special needle collection box for ultramicrosurgical procedures. Background Technology
[0002] Ultrasurgery, also known as supermicrosurgical techniques, refers to the use of a surgical microscope to magnify and manipulate tiny tissues with delicate microsurgical instruments and sutures. Ultrasurgery for lymphatic vessels and veins, a technique developed specifically for this purpose, utilizes ultramicrosurgical techniques. Under a microscope with magnification exceeding 30x, lymphatic vessels with a diameter of only 0.3–0.8 mm are anastomosed to adjacent small veins, allowing stagnant lymph fluid to flow directly into the veins through the anastomosis, thus reconstructing the lymphatic-venous return pathway. During the procedure, surgeons use specially designed ultramicrosurgical needles and sutures. The diameter of the sutures is only one-twentieth the diameter of an adult female's hair, making the procedure extremely difficult, but also resulting in minimal trauma, high safety, rapid recovery, and excellent outcomes.
[0003] Microsurgery requires 10-0, 11-0, and 12-0 surgical sutures, and the corresponding surgical needles are also very fine. If these surgical needles or sutures are lost during the operation, they are not easy to find. If they are lost, they can easily cause residues in the body. Therefore, it is necessary to count the surgical needles. Currently, there is no unified standard or special collection instrument for ensuring the correct number of surgical needles used in ultramicrosurgery during the operation. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a special needle collection box for ultra-microsurgical procedures, which can facilitate the counting of surgical needles and sutures and ensure that no loss occurs.
[0005] This utility model is achieved through the following technical solution:
[0006] A special needle collection box for ultramicrosurgery includes a box body with an open top, a magnet at the bottom of the box body, and an adhesive layer around the top of the magnet;
[0007] The box body is fitted with a cover at its opening, and the cover is fitted with a convex lens that allows observation of the interior of the box body from the outside.
[0008] Furthermore, the magnet is located at the center of the bottom of the box, and the cross-sectional area of the magnet is 1 / 3 to 1 / 2 of the cross-sectional area of the bottom of the box.
[0009] The gap between the outer side of the magnet and the inner wall of the box is filled with a layer of wax.
[0010] Furthermore, the adhesive layer covers the surface of the wax layer.
[0011] Furthermore, a 1-2mm thick layer of oil paper is bonded to the bottom of the adhesive layer.
[0012] Furthermore, the box has a cylindrical structure and is made of a transparent rigid material.
[0013] Furthermore, the convex lens is embedded in the center of the cover, and the outer diameter of the convex lens is equal to the inner diameter of the box.
[0014] The top of the outer wall of the box is provided with a connecting seat, and one side of the cover is hinged to the connecting seat by a connecting post.
[0015] Furthermore, the thickness of the magnet is 2-3 cm, and the thickness of the adhesive layer is 2-3 mm.
[0016] The beneficial effects achieved by this utility model compared with the prior art are as follows:
[0017] 1. During surgery, the used surgical needles and sutures are placed in the box. The magnet can attract the surgical needles, and the adhesive layer can stick to the surgical sutures, preventing the surgical needles and sutures from being lost. After a certain number are collected, the number in the box can be counted through the magnification effect of the convex lens on the cover, so as to ensure that the number of surgical needles is correct, avoid loss, and reduce the risk of residual surgical needles in the body.
[0018] 2. The magnet is located at the center of the bottom of the box, which can attract the surgical needles towards the center. This design makes it convenient for the convex lens to observe and count the number of surgical needles, thus improving accuracy.
[0019] 3. A 1-2mm thick layer of oil paper is bonded to the bottom of the adhesive layer. The oil paper layer is laid on the top surface of the wax layer. This design makes it easy to replace the adhesive layer and facilitates the reuse of the collection box next time.
[0020] 4. The lid and the box are hinged together, so the box can be opened simply by rotating the lid, which is convenient and easy to operate. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0025] In the description of this utility model, it should be understood that the terms "front," "rear," "upper," "lower," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The utility model will be further described below with reference to the accompanying drawings and embodiments.
[0026] like Figure 1-2 As shown, this embodiment discloses a needle collection box for ultra-microsurgical procedures, including a box body 1, a cover 2, a convex lens 3, and a magnet 4. The box body 1 is made of a transparent, rigid material and is designed as a cylindrical structure with an open top. A connecting seat is machined onto the top of the outer wall of the box body 1, and a protrusion is machined onto one side of the cover 2. The protrusion is hinged to the connecting seat via a connecting post 6. This design allows for quick opening of the box body 1 by rotating the cover 2.
[0027] A convex lens 3 is embedded in the center of the cover 2. The outer diameter of the convex lens 3 is equal to the inner diameter of the box 1. Through the convex lens 3, the interior of the box 1 can be observed from the outside. The magnet 4 is cylindrical and 3cm thick. The magnet 4 is placed in the center of the bottom of the box 1. The cross-sectional area of the magnet 4 is half the cross-sectional area of the bottom of the box 1. To fix the magnet 4, wax is filled into the gap between the outer side of the magnet 4 and the inner wall of the box 1 to form a wax layer 5. The cross-section of the wax layer 5 is annular. A 1.5mm thick annular oil paper layer 7 is laid on the surface of the wax layer 5, and then a 2mm thick adhesive layer is applied to the surface of the oil paper layer 7 to form an adhesive layer 8. With this design, the adhesive layer 8 can be replaced by replacing the oil paper layer 7.
[0028] The specific usage process of the ultra-microsurgical needle collection box described in this embodiment is as follows:
[0029] During microsurgical procedures, after each surgical needle is used, it is placed in the box 1. A magnet attracts the needle, and the adhesive layer 8 holds the sutures in place, preventing loss. Once a sufficient number have been collected, the convex lens 3 on the cover 2 magnifies the contents, making it easy to count the needles and sutures in the box 1. This ensures accurate counting, prevents loss, and reduces the risk of needles remaining in the body. For the next use, simply remove the oil paper layer 7 and replace it with a new adhesive layer 8. The process is simple and convenient.
