Embodiment 1
[0028] Example 1 A rapid extraction device for intraoperative pathological tissue
[0029] like Figure 1-6 In the shown embodiment, a device for rapidly extracting intraoperative pathological tissue includes a syringe 1, a piston 2 disposed in the syringe, a hollow push-pull rod 3 fixedly connected to the end of the piston 2, and a needle 4 disposed at the front end of the syringe 1 , the inner front end of the needle 4 is provided with an "I"-shaped tissue pushing mechanism extending to the inside of the piston 2; the rear end of the hollow push-pull rod 3 is provided with a "T"-shaped pushing mechanism, and the "T"-shaped pushing mechanism is The rear end of the hollow push-pull rod 3 penetrates the interior of the hollow push-pull rod 3 and extends to the rear end of the piston 2; a cavity 5 is provided inside the piston 2, and a first through hole 6 communicating with the cavity 5 is provided at the front end of the piston 2 , The rear end of the piston 2 is provided wit...
Embodiment 2
[0034] Example 2 A rapid extraction device for intraoperative pathological tissue
[0035] The structure of this embodiment is basically the same as that of Embodiment 1, the only difference being that: the front end surface of the front push plate 8 in this embodiment is provided with a slice 16 extending to the opening of the needle point of the needle head 4, and the slice 16 is as follows: Figure 7 As shown, it is a horizontal slice, and the horizontal slice is used to cut the pathological tissue when extracting the pathological tissue, so that the cell layers are more distinct, and two cell smears are prepared at a time for comparative observation.
Embodiment 3
[0036] Example 3 A rapid extraction device for intraoperative pathological tissue
[0037] The structure of this embodiment is basically the same as that of Embodiment 1, the only difference being that: the front end surface of the front push plate 8 in this embodiment is provided with a slice 16 extending to the opening of the needle point of the needle head 4, and the slice 16 is as follows: Figure 8 As shown, it is a "ten" type slice. "Ten"-shaped slices are used to cut pathological tissues when extracting pathological tissues, so that the cell layers are more distinct, and four cell smears are prepared at a time for comparative observation.
