Embodiment Construction

[0029] The present invention will be further described below in conjunction with drawings and embodiments.

[0030] refer to Figure 1-3 , a medical puncture device, comprising a puncture gun 1 and a puncture needle 2;

[0031] The puncture needle 2 is provided with an operating mechanism 21 and a locking mechanism 22 linked with the operating mechanism 21; when the puncture needle 2 is placed in the accommodating cavity 11 of the puncture gun 1, the operating mechanism 21 exposed to the outside of the puncture gun 1; operating the operating mechanism 21 drives the locking mechanism 21 to move in the accommodating cavity 11, and the locking mechanism 21 squeezes the elastic member 12 in the accommodating cavity 11, and contacts with the accommodating cavity The snap-lock mechanism 13 in the cavity 11 cooperates so that the snap-lock mechanism 22 is in an elastic locking state.

[0032] The puncture needle 2 includes a needle core 23 and a needle sheath 24; the head end of th...

Abstract

The invention provides a medical puncture device which comprises a puncture gun and a puncture needle. The puncture needle is provided with an operating mechanism and a clamping and locking mechanism in linkage with the operating mechanism, and the operating mechanism is exposed outside the puncture gun when the puncture needle is disposed in a containing cavity of the puncture gun; the operating mechanism is operated to drive the clamping and locking mechanism to move in the containing cavity, and the clamping and locking mechanism squeezes an elastic part in the containing cavity and is matched with a clamping and locking matching mechanism in the containing cavity to enable the clamping and locking mechanism to be in an elastic locking state. The medical puncture device is simple in structure, small in size and light in mass, convenience is brought to medical staff for actual use, and both structural stability and reliability are guaranteed.

Description

technical field [0001] The invention relates to a medical puncture device. Background technique [0002] With the continuous improvement of people's living standards, more and more tumors occur in the human body. In the process of clinical diagnosis and treatment, when the nature of tumors in some tissues is unknown, biopsy puncture techniques are often used to obtain suspicious tissues for pathological characterization and further treatment. Best way. [0003] Puncture examination is a very important invasive diagnosis and treatment technology in the current clinical diagnosis and treatment process. Although it will bring trauma to patients, the importance of examination to clinical diagnosis and treatment is undoubted, so it is important to minimize the harm to patients. A must. [0004] In the process of clinical diagnosis and treatment, when the pathological nature of suspicious lesions cannot be determined, medical image-guided puncture needles (ultrasound, X-ray or ...
