Embodiment

[0036] Please refer to Figure 1~3 , this embodiment provides a new type of needle 1000 . The novel needle 1000 includes: a main rod 100 , a sleeve 200 , a needle tube 300 and a support rod 400 .

[0037] The sleeve 200 is slidably sleeved on the main rod 100 . The main rod 100 has a channel 110 through which the medium passes. One end of the needle tube 300 fits with the main rod 100 and communicates with the flow channel 110 . One end of the strut 400 is hinged with the needle tube 300 , and the other end is hinged with the sleeve 200 , so that the sleeve 200 can push the needle tube 300 to open and close.

[0038] When the needle insertion is completed and the new needle 1000 reaches the hematoma, the needle tube 300 can be stretched by pushing the cannula 200, so that the needle tube 300 is opened relative to the main rod 100, thereby improving the volume of the new needle 1000. The extraction effect of the blood mass.

[0039] During the extraction process, it can be...

Abstract

The invention discloses a novel needle head and a hematoma crushing puncture instrument and relates to the field of medical instruments. The novel needle head comprises a main rod, a sleeve, a needletube and a branch rod. The sleeve is slidably sleeved on the main rod. The main rod is provided with a flow channel for media to pass through. One end of the needle tube is matched with the main rod and communicated with the flow channel. One end of the supporting rod is hinged to the needle tube, and the other end of the supporting rod is hinged to the sleeve so that the sleeve can push the needle tube to open and close. The hematoma crushing puncture instrument is provided with the novel needle head, is simple in structure, easy and convenient to operate, high in controllability and capableof effectively improving the blood drawing efficiency. For hematoma blocks which are large in size and thick, the extraction effect is very good. The operation difficulty and complexity are effectively reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a novel needle and hematoma crushing and puncturing instrument. Background technique [0002] In the process of minimally invasive puncture removal of intracranial hematoma, when the volume of the hematoma is large and the liquid part in the hematoma is relatively viscous, the efficiency of blood drawing is very low, and the extraction point needs to be adjusted continuously during the extraction process. The operation efficiency is low and the operation load is high. [0003] In view of this, this application is proposed. Contents of the invention [0004] The first object of the present invention is to provide a new type of needle, which has simple structure, easy operation, strong controllability, and can effectively speed up blood drawing efficiency. For larger and more viscous blood masses, the extraction effect is very good. It effectively reduces the difficulty and ...
