Description

Technical Field

[0001] The utility model relates to the technical field of puncture drainage devices, in particular to a surgical puncture drainage device. Background Art

[0002] Puncture technology is a minimally invasive treatment method that has gradually developed and applied with the development of modern imaging technology. For example, thoracic surgery will use a puncture drainage device for drainage treatment for pleural effusion or pus. The existing puncture drainage device generally includes a drainage gun, a puncture needle at the gun head and a drainage tube at the gun tail. The end of the drainage tube is connected to a negative pressure or non-negative pressure liquid collection container. During treatment, the medical staff holds the drainage gun and adjusts the puncture needle (a soft catheter with a needle) to penetrate the patient's chest cavity. During the drainage process, the staff needs to maintain the posture of holding the drainage gun. It is difficult to hold the drainage gun in the air for a long time. Once the drainage gun shakes, it will cause the puncture needle to move, which will cause the needle to fall off and the patient's puncture site to be moved.

[0003] In the prior art, for example, a thoracic surgical puncture drainage device in Chinese patent CN 219354103 U includes a drainage gun body, and a support device is arranged outside the drainage gun body, and the support device includes an assembly collar, a rotating seat, a support stand, a locking knob and a clamping assembly. The outer surface of the assembly collar is fixedly mounted with a rotating seat, and the support stand is movably mounted on the rotating seat. The surface of the support stand is sleeved with a locking knob, and the lower end of the support stand is fixedly mounted with a clamping assembly. Through the support device, when the medical staff uses it by hand, the drainage gun body can play a role of lifting and supporting through the support stand, and the position of the drainage gun can be fixed by the clamping effect of the clamping assembly, so that the cumbersome procedure of holding and waiting is omitted during long-term drainage work. The fixed position of the drainage gun can reduce the hidden danger of the puncture needle falling off after being pulled, and also prevent the puncture needle from moving the patient's puncture site when it is active. However, the patent still has the following problems.

[0004] In the above-mentioned patent, although the patent is provided with a clamping assembly for clamping the assembly to reduce the risk of the puncture needle falling out after being pulled, the length of the support frame provided in the patent is fixed. However, during treatment, due to the different body shapes of different patients and the influence of other conditions, the height of each puncture may also be different. Therefore, the support frame provided in the patent may be difficult to use for clamping at other heights, reducing the scope of use. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that during treatment, different patients have different body shapes and other conditions, and the height of each puncture may also be different. Therefore, the support stand provided in the patent may be difficult to use for clamping at other heights, reducing the scope of use. A surgical puncture drainage device is proposed to solve the problem.
