The utility model discloses a dental pulp sampling needle, which comprises a needle tip, a needle rod and a needle handle, the needle tip and the needle handle are respectively connected at both ends of the needle rod, the needle tip has a notch for sampling, the notch is arranged along the axial direction of the needle tip, and the needle handle is a flat structure. Since the tip of the needle is provided with a notch for sampling, compared with the pinhole sampling of the prior art needle, the notch of the needle tip is an open structure. In the process of one-time sampling, the sampling amount of the notch is obviously larger than that of the pinhole, and the notch sampling is more convenient than the pinhole sampling. The notch sampling can be carried out by scraping and poking, and the pinhole is only suitable for poking; in addition, the pulp sampling needle is also provided with The needle handle extends the length of pulp sampling needle, facilitates hand-held sampling and improves the quality of sampling. The flat needle handle avoids rolling during sampling, further facilitates hand-held sampling and improves sampling efficiency.
【技术实现步骤摘要】
牙髓取样针
本技术涉及用于牙髓取样的工具,具体涉及一种牙髓取样针。
技术介绍
在牙髓诊疗过程中,需要对牙髓进行取样分析,以判断患者的牙髓的健康状况。现有技术中采用注射器的针头进行牙髓取样,注射器的针头的针尖和针孔较小,通过针孔作为取样腔取样,一次性取样量小,并且针头的针栓(相对针尖的另一端,用于安装在注射器上)为圆柱形菱面结构,不适合手持,取样时容易滚动。
技术实现思路
本申请提供一种取样量较大及便于手持的牙髓取样针。一种实施例中提供一种牙髓取样针,包括针尖、针杆和针柄,针尖和针柄分别连接在针杆的两端,针尖具有用于取样的槽口,槽口沿着所述针尖轴向设置,针柄为扁平结构。进一步地,槽口从针尖的一端延伸至另一端,针尖的长度为8-12mm。进一步地,针杆为实心杆。进一步地,针杆与针尖连接的端部为实心结构。进一步地,针柄上设有防滑纹。进一步地,针柄包括依次连接缓冲部、防滑部和延长部,针柄的缓冲部与针杆连接,防滑部上设有防滑纹。依据上述实施例的牙髓取样针,由于针尖设有用于取样的槽口,相对于现有技术针头的针孔取样,本针尖的槽口为开放式结构,在一次取样过程中,槽口取样量明显大于针孔取样,并且槽口取样比针孔更为方便,槽口取样可通过刮取和戳取方式,针孔仅适用于戳取方式;另外,牙髓取样针还设有针柄,针柄延长了牙髓取样针的长度,方便手持取样,也提高了取样的质量,并且扁平结构的针柄,避免了取样过程中的滚动,进一步方便了手持取样,提高了取样效率。附图说明 ...
