[ background of the invention ]
Anesthesia means that a patient loses the feeling wholly or locally temporarily by a medicine or other methods to achieve the purpose of painlessness and provide conditions for surgical treatment or other medical examination and treatment. In the prior art, when an anesthetic needle is used for injecting anesthetic, an anesthesiologist needs to carefully master the puncture depth of the needle head, and needs to be more careful when spinal injection anesthesia is performed, so that mental fatigue of the anesthesiologist is increased.
Application No.: 201910618355X discloses an anesthesia needle for positioning type intraspinal anesthesia, which is used for solving the problem that the puncture depth of a puncture needle cannot be adjusted, and when the anesthesia needle is used by medical staff, the puncture difficulty can be reduced, and certain simplicity is achieved. However, the solution has a complex structure, which causes problems of high cost and large occupied space.
In order to substantially reduce the working intensity of an anesthesiologist, the development of a positioning type intraspinal anesthesia anesthetic needle which does not need manual reading is urgently needed.
[ summary of the invention ]
The invention aims to solve the problems in the prior art and provides a positioning type spinal anesthesia needle which can position and control the puncture depth of a needle head.
In order to achieve the purpose, the invention provides a positioning type anesthetic needle for intraspinal anesthesia, which comprises a needle cylinder and a needle head, wherein a first piston and a second piston are arranged in the needle cylinder, and the positioning type anesthetic needle is characterized in that: a first push rod is fixedly connected to the first piston, a second push rod is fixedly connected to the second piston, the first piston is located at the upper part of the second piston, the second push rod penetrates through the first piston, and the joint of the first piston and the second push rod is arranged in a sealing mode; the needle head is fixedly connected to the bottom of the second piston; a flow passage is arranged on the second piston, the upper end of the flow passage is communicated with a cavity between the first piston and the second piston, and the lower end of the flow passage is communicated with the needle head; the bottom of the needle cylinder is provided with a through hole, and the needle head can extend out of the through hole; the side wall of the first push rod is provided with scale marks, and the side wall of the second push rod is close to the scale marks of the first push rod.
Preferably, the cross sections of the rod bodies of the first push rod and the second push rod are semicircular, and the plane side walls of the rod bodies of the first push rod and the second push rod are close to each other.
Preferably, the flow channel is inclined, and the top of the flow channel is staggered with the bottom of the second rod body.
Preferably, the needle top is connected to the bottom of the second piston by a screw thread.
