背景技术Background technique
肺活检是在临床上诊断肺内病变尤其是占位性病变的重要手段之一，即为采用活检枪将病人肺部内发生病变部位的组织取出，然后进行化验从而来确定病情以用来确定治疗方案的一种辅助手术。其流程大致如下：根据病变位置，患者取仰卧、俯卧或侧卧位作CT扫描，病变位置薄层扫描，选择穿刺的最佳层面和皮肤穿刺点，置金属标志于进针点，重复CT扫描核实无误后在皮肤上用色笔标记穿刺点，用光标分别测出进针角度和允许进针最大深度。常规消毒皮肤，经皮局麻。麻醉成功后，根据病灶大小选择活检方法(小于2cm者针吸活检；大于2cm者针吸或切割活检)。在切割活检时，先将穿刺针芯、针套正确安装在穿刺枪并将穿刺枪设定在待激发状态，穿刺目标确定后，激发穿刺枪，穿刺针芯首先进入病变组织，部分病变组织处于活检槽中，穿刺针套随后进入。在此过程中，针套将取检槽中的病变组织裁切并套存于取检槽中。退出穿刺针，并取出取检槽中的病变组织，采集标本。目前医生在进行肺穿刺活检术时，先由电脑根据胸CT扫描照片的结果计算出进针角度之后，然后医生凭借经验进行进针活检，但是这种操作方式误差比较大，容易造成针尖端未刺入肿块，需要把活检针拔出来之后重新人工选取合适的角度进针，这样的操作方式不仅影响医生的活检取样效率，也给病人带来不必要的痛苦。Lung biopsy is one of the important methods for clinically diagnosing lung lesions, especially space-occupying lesions. It uses a biopsy gun to take out the tissue of the lesion in the patient's lungs, and then conducts laboratory tests to determine the condition. An adjunct to treatment options. The process is roughly as follows: according to the location of the lesion, the patient is placed in the supine, prone or side position for CT scanning, the lesion location is thin-layer scanned, the best layer of puncture and the skin puncture point are selected, a metal marker is placed at the needle entry point, and the CT scan is repeated After verification, mark the puncture point on the skin with a colored pen, and use the cursor to measure the needle insertion angle and the maximum allowable needle insertion depth. Routine disinfection of the skin, percutaneous local anesthesia. After successful anesthesia, select the biopsy method according to the size of the lesion (needle aspiration biopsy for less than 2 cm; needle aspiration or cutting biopsy for greater than 2 cm). When cutting a biopsy, first install the puncture needle core and needle sheath correctly on the puncture gun and set the puncture gun to the standby state. After the puncture target is determined, activate the puncture gun. In the biopsy well, the puncture needle cover then enters. During this process, the needle sheath cuts the diseased tissue in the retrieval groove and stores it in the retrieval groove. Withdraw the puncture needle, take out the diseased tissue in the sampling tank, and collect the specimen. At present, when doctors perform lung biopsy, the computer calculates the angle of insertion of the needle based on the results of the chest CT scan, and then the doctor conducts the needle biopsy based on experience. To puncture the tumor, it is necessary to pull out the biopsy needle and then manually select a suitable angle to insert the needle. This operation method not only affects the efficiency of biopsy sampling for doctors, but also brings unnecessary pain to patients.

本实用新型通过设置进针引导器，该进针引导器可任意调节活检枪的针筒从进针引导器穿过的角度，并可固定活检枪的进针方向；进一步通过角度指针指向刻度线上对应的角度，可直接读出导向管轴线方向(即活检枪进针方向)在竖直平面与进针点人体表面之间的角度。本实用新型的装置可精准定位肺活检进针方向与人体表面的角度，实现进针方向精准定位可调，无需医生根据经验进行进针活检，大大减少进针操作的误差，避免活检枪未刺入肿块的情况，避免多次进针对患者造成的伤害，提高肺穿刺活检术的手术效率，避免病人带来不必要的痛苦。The utility model is provided with a needle guide, which can arbitrarily adjust the angle at which the needle cylinder of the biopsy gun passes through the needle guide, and can fix the needle direction of the biopsy gun; further, the angle pointer points to the scale line The corresponding angle can be directly read the angle between the vertical plane and the human body surface at the needle insertion point in the axis direction of the guide tube (that is, the needle insertion direction of the biopsy gun). The device of the utility model can accurately locate the angle between the needle insertion direction of the lung biopsy and the surface of the human body, realize the precise positioning and adjustment of the needle insertion direction, and do not need the doctor to perform the needle biopsy according to experience, greatly reduce the error of the needle insertion operation, and avoid the biopsy gun from not stabbing In the case of a tumor, it can avoid the harm caused by multiple injections to the patient, improve the operation efficiency of lung biopsy, and avoid unnecessary pain for the patient.
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本实用新型原理的前提下，还可以做出若干改进和补充，这些改进和补充也应视为本实用新型的保护范围。The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and supplements can also be made, and these improvements and supplements are also It should be regarded as the protection scope of the present utility model.
