Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an ultrasonic puncture needle which is easy to grasp and can be quickly identified. Background Art

[0002] Puncture is the process of passing a puncture needle through the skin to reach the patient's lesion site, thereby forming a channel between the outside world and the lesion site, and taking biopsy samples of the lesion site. The purpose of puncture is to form a channel between the body surface and the lesion site, so that various minimally invasive interventional surgical techniques can be implemented, thereby achieving the goal of precise and targeted treatment.

[0003] The needle tube and needle holder of a traditional puncture needle are fixedly connected. This design has a disadvantage: when medical staff use the puncture needle, the comfort and strength control of gripping the needle holder may be different due to the different sizes of their palms. This difference may affect the strength control of the puncture, so this problem needs to be solved. In addition, during the puncture process, if there is insufficient experience or poor control, the puncture needle may be slightly bent, especially when the bend occurs at the scale, which will affect the reading of the puncture depth, so this problem needs to be solved. Utility Model Content

[0004] The purpose of the utility model is to provide an ultrasonic puncture needle that is easy to grasp and can be quickly identified, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an ultrasonic puncture needle that is easy to grasp and can be quickly identified, comprising a needle tube, a plurality of scale lines are evenly distributed on the outer wall of the needle tube at unit distances along its length direction, a connecting part is fixed to the root of the needle tube, and the connecting part is detachably mounted on the connecting part of the needle seat.

[0006] The connecting portion at the root of the needle tube is threadably mounted on the connecting portion of the needle seat.

[0007] An elastic buffer layer is arranged on the upper part of the needle seat.

[0008] The needle seat is provided with a plurality of finger holes.

[0009] The number of the finger holes is 2-5.

[0010] A plurality of reflective grooves are arranged on the upper part of the needle tip of the needle tube.

[0011] A plurality of reinforcing rings are arranged at intervals in the needle tube, and the reinforcing rings are located at the scale lines.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] 1. The outer wall of the needle tube of the utility model has multiple scale lines evenly distributed at unit distances along its length direction, which are used to judge the depth of insertion;

[0014] 2. The root of the needle tube of the utility model is fixed with a connecting part, which is detachably mounted on the connecting part of the needle seat. The size of the needle seat can be adjusted according to the different sizes of the palms of medical staff to improve the comfort and strength control of grasping the needle seat. This ensures the best strength control of puncture and ensures the smooth progress of puncture. The size of the needle tube can also be adjusted according to the needs of puncture. Therefore, the detachable design of the needle tube and needle seat solves these problems well and meets a wider range of application needs;

[0015] 3. The needle tip of the needle tube of the utility model is provided with a plurality of reflective grooves, which can enhance the effect of ultrasonic reflection, improve the effect of ultrasonic recognition and imaging, and improve the success rate of surgery;

[0016] 4. The needle tube of the utility model is provided with multiple reinforcing rings at intervals, and the reinforcing rings are located at the scale lines to enhance the strength of the needle tube, avoid slight bending of the puncture needle due to lack of experience or poor control, and ensure the accuracy of the puncture depth reading.
