Description

Technical Field

[0001] This utility model relates to the field of biopsy puncture needles, and in particular to a biopsy puncture needle that facilitates depth control. Background Technology

[0002] A biopsy needle is a tool used in medical diagnosis. Guided by imaging equipment, it can accurately puncture the lesion site in the body to obtain tissue samples for pathological examination. This technique is commonly used in cancer diagnosis and can help doctors determine the nature of the lesion, cell type, degree of differentiation, and whether it is suitable for molecular targeted therapy.

[0003] Existing biopsy needles are generally quite thin to facilitate insertion into the patient's body, making them prone to bending during transport. Since the needle's puncture and handle are fixedly connected, a bend in the puncture section necessitates replacing the entire needle, which is wasteful. Furthermore, the length and depth of insertion of existing needles largely depend on the physician's experience. Less experienced physicians may fail to puncture the patient on the first attempt, prolonging the puncture time.

[0004] Therefore, those skilled in the art have provided a biopsy puncture needle that facilitates depth control to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biopsy puncture needle that facilitates depth control. The puncture needle is threadedly connected to the main body via a threaded rotating column. When the puncture needle is damaged, it can be replaced via the threaded rotating column. Adjusting the length of the support modules on both sides of the main body allows control over the depth to which the puncture portion enters the main body.

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] Reference Figure 1-3 The present invention provides an embodiment of a biopsy puncture needle for easy depth control, comprising a main body 1, with fixing blocks 2 fixedly disposed on both the front and rear ends of the main body 1, and first snap-fit ​​blocks 4 fixedly disposed on one side of the inner wall of each of the two fixing blocks 2, and support modules 6 fixedly disposed on both sides of the main body 1, with a threaded rotating column 5 threadedly sleeved on the rear end of the main body 1, and a puncture needle 8 fixedly disposed on one side of the threaded rotating column 5, with a placement groove 7 opened on one side of the upper end face of the puncture needle 8, and a puncture head 9 fixedly disposed on one side of the puncture needle 8, and a sliding groove 3 opened on the other side of the inner wall of each of the two fixing blocks 2.

[0025] Specifically, during use, the front and rear ends of the main body 1 are fixedly equipped with fixing blocks 2. The inside of the fixing blocks 2 is equipped with a first snap-fit ​​block 4. The sliding groove 3 opened in the fixing blocks 2 allows the snap-fit ​​rod 106 inside the main body 1 to enter the fixing blocks 2, so that the second snap-fit ​​block 103 connected to the snap-fit ​​rod 106 can contact the first snap-fit ​​block 4. A threaded rotating column 5 is threadedly fitted on one side of the main body 1. The threaded rotating column 5 is connected to the puncture needle 8. The upper end face of the puncture needle 8 is equipped with a placement groove 7. During use, the placement groove 7 enters the tumor and can cooperate with the main body 1 to allow the biopsy sample to be received inside the placement groove 7. The puncture needle 8 is fixed with a puncture head 9, which facilitates puncture.

[0026] Reference Figure 4The main body 1 includes a connecting cylinder 101, a connecting rod 107 slidably disposed on one side of the connecting cylinder 101, a snap-fit ​​rod 106 fixedly disposed at the front and rear ends of the connecting rod 107, a second snap-fit ​​block 103 fixedly disposed at the front end of each of the two snap-fit ​​rods 106, a fixed enclosure 105 fixedly disposed on one side of the connecting cylinder 101, through openings 102 on both sides of the connecting cylinder 101, and a threaded block 104 fixedly disposed on the inner wall of the other side of the connecting cylinder 101.

[0027] Specifically, during use, the main structure of the main body 1 includes a connecting cylinder 101, inside which is a connecting rod 107. The connecting rod 107 can hold the puncture needle 8. On both sides of the connecting rod 107 are locking rods 106. The locking rods 106 pass through the port 102 and enter the outside of the main body 1. The locking rods 106 are connected to a second locking block 103. The second locking block 103 can contact the first locking block 4 to keep the connecting rod 107 stable inside the main body 1, requiring medical personnel to use considerable force to move the connecting rod 107 downward. The fixing surround 105 on one side of the connecting cylinder 101 allows the connecting rod 107 to slide more stably during use. On the other side of the main body 1, there is a threaded block 104 inside, which allows the main body 1 to connect with the threaded rotating column 5 during use.

[0028] Reference Figure 2 The support module 6 includes a fixing plate 601, a connecting plate 603 is threaded on the front end face of the fixing plate 601, a threaded cylinder 604 is fixedly installed on the front end face of the connecting plate 603, a threaded rod 605 is threaded inside the threaded cylinder 604, fixing screws 602 are threaded on the four corners of the front end face of the connecting plate 603, and a pressing plate 606 is fixedly installed on the front end face of the threaded rod 605.

[0029] Specifically, during use, adjusting the length of the support module 6 can adjust the depth to which the puncture needle 8 enters the patient's body. The support module 6 includes a fixing plate 601, which can be fixed to the front and rear ends of the main body 1. The fixing plate 601 can be connected to the connecting plate 603 via fixing screws 602. The connecting plate 603 is connected to a threaded cylinder 604, and a threaded rod 605 is provided inside the threaded cylinder 604. When the threaded rod 605 is rotated, its position inside the threaded cylinder 604 can be adjusted, making it easy to adjust the length of the support module 6. The threaded rod 605 is connected to a pressing plate 606, which makes the support module 6 more stable when placed on the patient.

[0030] Working principle: The groove 3 opened in the fixing block 2 allows the locking rod 106 inside the main body 1 to enter the fixing block 2, so that the second locking block 103 connected to the locking rod 106 and the first locking block 4 come into contact, so that the connecting rod 107 is kept stable inside the main body 1, and medical staff have to use more force to move the connecting rod 107 downward.

[0031] When the connecting rod 107 moves downward, the lower end of the connecting rod 107 can cut the tumor inside the placement groove 7 opened by the puncture head 8, so that the tumor can remain inside the placement groove 7 when the puncture needle 8 is withdrawn.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
