In the figure: 1. a housing; 11. a valve body; 12. a knob; 2. a hollow puncture needle; 3. puncturing the sheath; 31. a cap body; 4. a pintle; 41. and a dust cover.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Referring to fig. 1-3, the present invention provides the following technical solutions: an improved lancet with anesthetic injection, comprising: casing 1, hollow pjncture needle 2, puncture sheath 3 and pintle 4, wherein:
a valve body 11 is arranged in the housing 1, a valve rod of the valve body 11 penetrates through the housing 1 and is connected with a knob 12, a character mark for indicating the opening and closing of the valve body 11 is printed on one side of the housing 1, the opening and closing of the valve body 11 can be rapidly controlled by rotating the knob 12, and an indication arrow mark can be printed on the surface of the knob 12 by utilizing the printed character mark (such as on, off and the like), so that a user can rapidly judge the opening and closing state of the valve body 11.
In order to enable the puncture needle to be inserted in the process of treating the tumor, the puncture needle is set to be the hollow puncture needle 2, one end of the hollow puncture needle 2 is communicated with the water outlet end of the valve body 11, and the hollow puncture needle 2 can be used for ensuring that the anesthetic can be injected through the hollow puncture needle 2 while the puncture in the normal production is ensured.
In order to ensure the normal operation of the puncture operation and the subsequent operations, a puncture sheath 3 can be sleeved on the outer part of the hollow puncture needle 2, and the top end of the puncture sheath 3 is sleeved with a cap body 31; when the hollow puncture needle 2 is used for puncture, the puncture sheath 3 is sleeved outside the hollow puncture needle 2, in addition, the outer diameter of the hollow puncture needle 2 is matched with the inner diameter of the puncture sheath 3, when a puncture operation is carried out, the puncture sheath 3 can be punctured into the body of a patient together with the hollow puncture needle 2, and the cap body 31 facilitates the pulling and inserting of the hollow puncture needle 2 and the puncture sheath 3.
