Problems solved by technology

Under normal circumstances, analgesic and anti-inflammatory drugs need to be injected at the surgical site immediately after the above treatment. This two-step method has at least two disadvantages. First, it increases the pain of the patient. Second, the injection site only It may be the general surgical site, and the accuracy of site selection is poor
[0004] On the other hand, the knife body of the current needle knife generally adopts a double-sided sharp structure, which can only be used for sharp peeling, but not for blunt peeling.

Embodiment Construction

[0012] Such as figure 1 As shown, the present embodiment mainly consists of a hollow needle body 2 and a knife body 1 at the lower end of the needle body 2 . The hollow part of the needle body 2 is the liquid medicine channel 3 , the upper end of the liquid medicine channel 3 is connected with the needle cap 5 , and the lower end communicates with the liquid medicine hole 6 provided on the knife body 1 .

[0013] A needle handle 4 is arranged on the upper end of the needle body 2 . When in use, hold the needle handle 4 to pierce the knife body 1 into the surgical site. After the stripping is completed, remove the needle cap 5 and connect the syringe to the liquid medicine channel 3 to perform drug injection.

[0014] see figure 2 , the cross-section of the cutter body 1 shows that one side is sharp and the other side is smooth.

Abstract

The present invention provides an injection needle knife. A needle body is a hollow structure, and the hollow part is a liquid medicine channel (3). The lower end of the liquid medicine channel (3) is communicated with one or more than one liquid medicine holes (6) at a knife body (1). After the desquamation operation is finished, only a common needle handle is required being screwed off, and the needle knife can be used for injecting medicine, which not only reduces the times for inserting needle, but the injection position can also be selected exactly and conveniently.
