背景技术Background technique
为了明确椎体病变的病理性质，对诊断困难的病例及需要接受经皮穿刺椎体成形术的病例，需要使用环钻钻取椎体骨质行病理检查。但在临床应用中，在经椎弓根穿刺良好的情况下，部分患者仍不能取到椎体骨质，不利于明确病变性质。In order to clarify the pathological nature of vertebral body lesions, for cases that are difficult to diagnose and cases that require percutaneous vertebroplasty, it is necessary to use a trephine drill to obtain vertebral body bone for pathological examination. However, in clinical application, even though the pedicle puncture is good, some patients still cannot obtain vertebral bone, which is not conducive to clarifying the nature of the lesion.
普通环钻取出椎体骨质的原理是：在经椎弓根穿刺建立良好工作通道的基础上，环钻经工作通道向前旋转钻进1-1.5厘米，此时，在环钻内包含了一段圆柱形骨质，其远端与椎体内的其他骨质相连；椎体骨密度正常的情况下，由于环钻内骨质与环钻内壁间摩擦力较大，此时快速拔出环钻，一般可以将圆柱形骨质远端拔断，从而取出骨质。但在临床工作中发现，部分患者由于骨质疏松及椎体破坏较严重，其骨质病理性破坏、疏松，因而与环钻内壁间的摩擦力减小，拔出环钻的摩擦力不足以拔断样本骨质，所以不能取出骨块进行病理学检查。The principle of ordinary trepanation to remove vertebral bone is: on the basis of establishing a good working channel through the pedicle puncture, the trephine drills forward 1-1.5 cm through the working channel. At this time, the trephine contains A section of cylindrical bone, the distal end of which is connected to other bone in the vertebral body; when the bone density of the vertebral body is normal, due to the high friction between the bone in the trephine and the inner wall of the trephine, the ring can be quickly pulled out. The drill can generally pull off the distal end of the cylindrical bone, thereby taking out the bone. However, it is found in clinical work that some patients have pathological bone destruction and loosening due to osteoporosis and severe vertebral body damage, so the friction force between the inner wall of the trephine and the trephine is reduced, and the friction force for pulling out the trephine is not enough. The sample bone was pulled out, so bone fragments could not be removed for pathological examination.

As shown in Figure 3, when the push-pull rod 7 is at a high position, the inner side of the overturning body 9 is pulled up by the swing bar 10, and the two overturning bodies 9 are brought together to form a cylinder that is the same as the outer contour of the polygonal columnar tube 6, without affecting multiple The axial sliding of the prismatic tube 6 in the polygonal prismatic cavity; The two sides are flipped 90 degrees and stuck on the end face of the polygonal columnar cavity, and the position of the polygonal columnar tube 6 is locked in the polygonal columnar cavity, so that the drill pipe 2 is locked on the polygonal columnar tube 6 .
使用时，使钻头1向下、取骨管4向上将钻杆2安装在的多棱柱状管6上，通过手柄3旋转钻头1在骨头上切开环状槽，并持续环切，直到环状槽的深度达到1-1.5厘米的取样要求；然后取下钻杆2，翻转后使取骨管4向下、钻头1向上将钻杆2安装在的多棱柱状管6上，并将压板8下压，使推拉杆7位于低位，将钻杆2锁定在多棱柱状管6上，把取骨管4伸进环状槽的底部，由于倒刺5具有一定的弹性，倒刺5的顶端抵靠在样本柱体的根部，增加取骨管4与样本柱体的摩擦力，此时拔出钻杆2即可将样本拔断并取出。也可以通过旋转取骨管4利用倒刺5在样本的根部切出根部环槽，然后再拔出钻杆2。When in use, make the drill bit 1 downward and the bone-taking tube 4 upward to install the drill rod 2 on the polygonal columnar tube 6, rotate the drill bit 1 through the handle 3 to cut a ring-shaped groove on the bone, and continue the circumcision until the ring The depth of the shaped groove reaches the sampling requirement of 1-1.5 centimeters; then take off the drill rod 2, turn over and make the bone-taking pipe 4 downward and the drill bit 1 upward to install the drill rod 2 on the polygonal columnar tube 6, and press the plate 8 press down, make the push-pull rod 7 be in the low position, lock the drill rod 2 on the polygonal columnar pipe 6, stretch the bone-taking pipe 4 into the bottom of the annular groove, because the barb 5 has certain elasticity, the barb 5 The top abuts against the root of the sample cylinder, increasing the frictional force between the bone-taking tube 4 and the sample cylinder. At this time, the sample can be pulled out and taken out by pulling out the drill rod 2 . It is also possible to use the barb 5 to cut out the root ring groove at the root of the sample by rotating the bone taking tube 4, and then pull out the drill rod 2.
