Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an abdominal puncture device. Background Technology

[0002] An abdominal paracentesis device is a medical device used to perform punctures in the abdomen. Its applications are very broad, primarily for abdominal punctures, including those in the abdominal cavity, liver, pancreas, gallbladder, etc., to obtain tissue or fluid samples for disease diagnosis and treatment. In addition, abdominal paracentesis devices are also commonly used for abdominal cyst puncture and ascites removal to help doctors diagnose and treat patients' conditions.

[0003] As mentioned in the published Chinese patent, an abdominal paracentesis device, application number CN202322480820.2, is described as follows: "An abdominal paracentesis device includes a support plate with an arc-shaped lower end face. A longitudinally penetrating puncture hole is provided on the side wall of the support plate. Fixing straps are connected to both ends of the support plate. Storage grooves are provided in the inner walls on both sides of the support plate. One end of the fixing strap extends into the storage groove, and a winding mechanism for winding the fixing strap is provided inside the storage groove. A puncture needle is provided on the upper side of the support plate, and a guiding mechanism is provided between the puncture needle and the support plate. This invention can fix the position of the support plate and the puncture hole, thereby positioning the overall puncture position and maintaining a certain stability during subsequent punctures. It can guide the puncture direction of the puncture needle, avoiding the displacement of the puncture needle position during puncture and affecting the final puncture effect. After puncture, the reset spring applies force to assist the puncture needle in quickly resetting and moving out of the patient's body."

[0004] The aforementioned patent achieves stable support for the abdominal paracentesis device through structural design and improvements, ensuring a certain degree of stability during subsequent punctures. While this method achieves the claimed technical effect, our simulations revealed certain shortcomings in this solution:

[0005] In practical use, the existing abdominal paracentesis devices are relatively large in size and have a complex structural design. The large support plate can obstruct the view of medical staff to some extent, resulting in an unclear and unintuitive field of vision during puncture. At the same time, the entire device needs to be held during puncture, which takes up a lot of space in the hands of medical staff, making it inconvenient to grasp the puncture device itself. This can lead to inconvenience in operation, unstable puncture, or even medical accidents.

[0006] Therefore, in response to the problems existing in the current technology, such as those mentioned above, we have designed a more convenient abdominal paracentesis device that does not affect the puncture field of view and can provide stable support for the puncture needle after puncture. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an abdominal paracentesis device, comprising a puncture device body, a puncture needle tube, and a support assembly. The puncture needle tube is disposed at the bottom of the puncture device body, and the support assembly is disposed on the puncture needle tube. Limiting slides are fixed in a ring at equal intervals near the upper part of the puncture needle tube. The support assembly includes a semi-circular support plate one and a semi-circular support plate two. A semi-circular positioning ring one is integrally formed at the center of the top of the semi-circular support plate one, and a limiting slide groove one is formed on the inner wall of the semi-circular positioning ring one. A semi-circular positioning ring two is integrally formed at the center of the top of the semi-circular support plate two, and a limiting slide groove two is formed on the inner wall of the semi-circular positioning ring two.

[0009] As a further embodiment of this utility model: a docking groove 1 is provided on both the left and right sides of one side wall of the semicircular support disk, and a docking groove 2 is provided on the side wall of the semicircular support disk 1 near each docking groove 1. A permanent magnet 1 is provided on the inner wall of both the docking groove 1 and the docking groove 2.

[0010] As a further embodiment of this utility model: both the left and right sides of the sidewall of the semicircular support disk are fixed with docking blocks 1, and the sidewall of the semicircular support disk 2 and the position close to each docking block 1 are fixed with docking blocks 2, and both docking blocks 1 and docking blocks 2 are permanent magnets 2.

[0011] As a further embodiment of this utility model: the sizes of the first docking block and the second docking block are adapted to the sizes of the first docking groove and the second docking groove, and the first docking block and the second docking block are respectively adsorbed into the inner cavities of the first docking groove and the second docking groove.

[0012] As a further embodiment of this utility model: the first limiting slide groove and the second limiting slide groove are the same in size and length, and the limiting slide strips are respectively adapted to the first limiting slide groove and the second limiting slide groove. When the first semicircular support plate and the second semicircular support plate are closed, the multiple limiting slide strips are respectively limited and engaged in the first limiting slide groove and the second limiting slide groove.

[0013] As a further embodiment of this utility model: the interior of both the first semicircular support plate and the second semicircular support plate is hollow and designed as a bowl-shaped structure, and the top of both the first semicircular support plate and the second semicircular support plate is provided with ventilation holes.

[0014] As a further embodiment of this utility model: medical double-sided adhesive is pasted on the bottom of both the first and second semi-circular support plates, and release paper is pasted on the bottom of the medical double-sided adhesive.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This application, through the designed structure of the puncture device body, puncture needle tube, semi-circular support plate one, and semi-circular support plate two, etc., allows for detachable assembly of the support components onto the puncture needle tube. During puncture, the puncture device body can be used directly without affecting the medical staff's field of vision. After puncture, semi-circular support plate one and semi-circular support plate two can be closed onto the puncture needle tube, thereby achieving stable support for the puncture needle tube and ensuring the stability of the entire puncture device body on the patient's body. This design avoids the problem of increasing the overall size and affecting the field of vision due to excessive structural modifications to the puncture device body. On the other hand, the post-installed support also ensures that the puncture device body maintains a stable state after entering the patient's body. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4An abdominal paracentesis device includes a trocar body 1, a trocar tube 2, and a support assembly 3. The support assembly 3 can be made entirely of transparent plastic to ensure portability while allowing observation of its internal structure. The trocar tube 2 is located at the bottom of the trocar body 1, and the support assembly 3 is located on the trocar tube 2. Limiting slide strips 4 are fixed in a ring at equal intervals near the upper part of the trocar body. The support assembly 3 includes a semi-circular support plate 301 and a semi-circular support plate 302. A semi-circular positioning ring 5 is integrally formed at the center of the top of the semi-circular support plate 301, and a limiting slide groove 6 is formed on the inner wall of the semi-circular positioning ring 5. A semi-circular positioning ring 11 is integrally formed at the center of the top of the semi-circular support plate 302, and a limiting slide groove 12 is formed on the inner wall of the semi-circular positioning ring 11.

[0025] Please see Figure 2-3 In this embodiment, the left and right sides of the sidewall of the semicircular support disk 301 are provided with docking grooves 8, and the sidewall of the semicircular support disk 301 near each docking groove 8 is provided with docking groove 9. The inner walls of docking groove 8 and docking groove 9 are provided with permanent magnets. The left and right sides of the sidewall of the semicircular support disk 302 are fixed with docking blocks 13, and the sidewall of the semicircular support disk 302 near each docking block 13 is fixed with docking blocks 14. Both docking blocks 13 and docking blocks 14 are permanent magnets. The size of docking blocks 13 and docking blocks 14 is adapted to the size of docking grooves 8 and 9, and docking blocks 13 and docking blocks 14 are respectively adsorbed in the inner cavities of docking grooves 8 and 9.

[0026] Specifically, the docking grooves 8 and 9 on the semicircular support disk 301 and the docking blocks 13 and 14 fixed on the semicircular support disk 302 are both magnetic structures. When the semicircular support disk 301 and the semicircular support disk 302 are closed, the docking blocks 13 and 14 enter the docking grooves 8 and 9 respectively. Through the magnetic effect of the magnets, the docking blocks 13 and 14 can be attracted to the inner cavity of the docking grooves 8 and 9 respectively, thus providing a good attraction force for the closure of the semicircular support disk 301 and the semicircular support disk 302 and preventing them from loosening.

[0027] Please see Figure 1-3 In this embodiment, the first limiting slide groove 6 and the second limiting slide groove 12 are the same size and length. The limiting slide strips 4 are adapted to the first limiting slide groove 6 and the second limiting slide groove 12 respectively. When the first semicircular support plate 301 and the second semicircular support plate 302 are closed, the multiple limiting slide strips 4 are respectively limited and engaged in the first limiting slide groove 6 and the second limiting slide groove 12.

[0028] Specifically, since there are multiple limiting slides 4, and limiting slide grooves 6 and 12 are respectively provided on the semi-circular support plate 1 301 and the semi-circular support plate 2 302, the entire support assembly 3 can be limited by the limiting slides 4 when it slides on the puncture needle tube 2, so as to prevent the support assembly 3 from rotating and ensure that the support assembly 3 is stably attached to the patient's skin.

[0029] Please see Figure 2-4 In this embodiment, both the first semicircular support plate 301 and the second semicircular support plate 302 are hollow inside and designed as bowl-shaped structures. Both the first semicircular support plate 301 and the second semicircular support plate 302 have ventilation holes 7 at their tops.

[0030] Specifically, since both the semi-circular support plate 1 301 and the semi-circular support plate 2 302 are designed in the shape of a bowl, and the top surface has a ventilation hole 7 that communicates with the interior, it can avoid the lack of air permeability caused by the support component 3 supporting the patient's skin, and can ensure the dryness of the lesion.

[0031] Please see Figure 1-4 In this embodiment, medical double-sided adhesive 10 is pasted on the bottom of both the semi-circular support plate 1 301 and the semi-circular support plate 2 302, and release paper is pasted on the bottom of the medical double-sided adhesive 10.

[0032] Specifically, by using the medical double-sided adhesive 10, the entire support component 3 can be attached around the patient's lesion, thereby providing stability to the support component 3 and ensuring the stability of the puncture device body 1.

[0033] In practical use:

[0034] Medical staff first need to use the puncture device body 1 and the puncture needle tube 2 to perform puncture operation at the patient's lesion. After the puncture is completed, since other work needs to be done, the entire puncture device body 1 needs to be kept stable. In current technology, tweezers or the method mentioned in application number CN202322480820.2 are generally used to stabilize the puncture device body 1. However, in this application, the semi-circular support plate 1 301 and the semi-circular support plate 2 302 can be directly taken and the release paper on the medical double-sided adhesive 10 can be torn off. Then, the semi-circular support plate 1 301 and the semi-circular support plate 2 302 can be closed, so that the semi-circular positioning ring 1 5 and the semi-circular positioning ring 2 11 can wrap the puncture needle tube 2 and allow multiple limiting slides 4 to enter the limiting slide groove 1 6 and the limiting slide groove 2 12 respectively.

[0035] When the semicircular support disk 1 301 and the semicircular support disk 2 302 are closed, the docking block 1 13 enters the docking groove 1 8 and is attracted and fixed thereto, and the docking block 2 14 enters the docking groove 2 9 and is attracted and fixed thereto, thereby realizing the closure and fixation of the semicircular support disk 1 301 and the semicircular support disk 2 302 to form a whole circle structure.

[0036] Finally, the support assembly 3, consisting of semi-circular support plate 1 301 and semi-circular support plate 2 302, slides downwards. Semi-circular support plate 1 301 and semi-circular support plate 2 302 slide vertically downwards through the limiting guide of the limiting slide bar 4 until the bottom of semi-circular support plate 1 301 and semi-circular support plate 2 302 contacts the patient's skin. Medical double-sided adhesive 10 is used to bond with the patient's skin. The bonding of semi-circular support plate 1 301 and semi-circular support plate 2 302 stabilizes the puncture needle tube 2, thereby stabilizing the puncture device body 1 and ensuring the stability of the puncture device body 1 after puncture.

[0037] It should be noted that the solution provided by this technology can ensure the compactness of the puncture device body 1 during puncture, without affecting the operation and field of view, and can also achieve the stability of the puncture device body 1 after puncture, which is more practical than the existing technology.

[0038] It should also be noted that, in order to avoid the reuse of medical waste, since the puncture device body 1 comes into contact with the patient's bodily fluids and the support component 3 comes into contact with the patient's skin, and there may even be drips on the support component 3, the puncture device body 1 and the support component 3 should be treated as single-use products. During production, the puncture device body 1 and the support component 3 can be placed in the same package for easy matching and convenient use by medical staff.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
