In the aforesaid this multichannel guide rod, an end of the guide rod body of rod is provided with conical head, and the outer wall of the other end is provided with skid resistant course.Skid resistant course is set, can prevents effectively that the multichannel guide rod is from landing on hand.
In the aforesaid this multichannel guide rod, the outer wall of the guide rod body of rod is provided with scale, and wherein zero graduation is arranged on the end of conical head.Scale is set lets the doctor understand the length that guide rod inserts human body constantly, thereby improve the success rate of operation.
In the aforesaid this multichannel guide rod, the length of the said guide rod body of rod is 100mm～300mm.
In the aforesaid this multichannel guide rod, the length of the said guide rod body of rod is 200mm.
In the aforesaid this multichannel guide rod, the external diameter of the guide rod body of rod is 2mm～15mm.
In the aforesaid this multichannel guide rod, the external diameter of the guide rod body of rod is 8mm.
In the aforesaid this multichannel guide rod, the aperture of centralized positioning through hole and assist location through hole is 0.7mm～2mm.
In the aforesaid this multichannel guide rod, the aperture of centralized positioning through hole and assist location through hole is 1.4mm.
In the aforesaid this multichannel guide rod, the said guide rod body of rod is cylindrical.
Compared with prior art, because this utility model is provided with 1 to 2 assist location through hole, need not in use guide rod is taken off; Only need the rotating guide body of rod to reorientate; Compare with traditional guide rod, can save great amount of time, effectively improve operation efficient.
Because the end at the guide rod body of rod is provided with conical head, can prevent effectively that the end of guide rod from hurting other organs and tissue when inserting human body, because the outer wall of the other end of the guide rod body of rod is provided with skid resistant course, can effectively prevent guide rod landing from hands.
Owing on the outer wall of the guide rod body of rod, be provided with scale, can let the doctor understand the length that guide rod inserts human body constantly, can improve the success rate of operation.
