[0031] Reference below Figures 1 to 4 A biopsy drill 100 and a spinal vertebral biopsy tool assembly according to an embodiment of the present invention are described.

[0032] like Figure 1 As shown, the biopsy drill 100 according to an embodiment of the present invention includes a drill tube 110 .

[0033] The drill pipe 110 is a hollow structure and is provided with a toothed drill opening 111 and a tightening recess 112 . The toothed drill opening 111 is provided at the end of the drill pipe 110 , and the tightening recess 112 is provided on the drill pipe 110 and above the toothed drill opening 111 .

[0034] like Figure 1 As shown, the drill tube 110 is a hollow long thin tube, and a sharp serrated drill hole 111 is provided at one end of one side of the drill tube 110 for cutting bone tissue. The cut bone tissue enters the drill tube 110, and the tightening recess 112 is provided above the serrated drill hole 111 and is very close to the serrated drill hole 111. When the bone tissue in the drill tube 110 passes through the tightening recess 112, the internal channel of the drill tube 110 becomes narrower, and the bone tissue is squeezed deeper into the drill tube 110. At the same time, because the internal channel of the drill tube 110 becomes narrower, the bone tissue cannot easily slide out of the drill tube 110.

[0035] The biopsy drill 100 in the embodiment of the present invention is provided with a tightening recess 112, so that the internal passage of the drill tube 110 becomes narrower, so that the bone tissue inside the drill tube 110 that has passed through the tightening recess 112 cannot easily slip out of the drill tube 110, thereby increasing the amount of material collected. The biopsy drill 100 in the embodiment of the present invention can increase the amount of material collected by adding a tightening recess 112 to the drill tube 110 provided with a toothed drill opening 111, is easy to operate, and causes little trauma to the patient.

[0036] In some specific embodiments of the present invention, the drill pipe 110 is provided with a pressure-equalizing port 113, which is provided on the drill pipe 110 and above the tightening recess 112. By providing the pressure-equalizing port 113, the internal and external air pressures of the drill pipe 110 are balanced to prevent the bone tissue from slipping out of the drill pipe 110 under the action of the atmospheric pressure when the drill pipe 110 is pulled out.

[0037] In some specific embodiments of the present invention, the equalizing pressure opening 113 is inclined and gradually penetrates into the center of the drill pipe 110 in a direction away from the toothed drill opening 111. The equalizing pressure opening 113 is inclined to prevent bone tissue from directly slipping out of the equalizing pressure opening 113 when bone tissue enters the drill pipe 110.

[0038] In some specific embodiments of the present invention, there are multiple equalizing pressure ports 113, which are evenly distributed on the drill pipe 110. Multiple equalizing pressure ports 113 are provided, and the equalizing pressure ports 113 are evenly distributed on the drill pipe 110, so that the air pressure inside and outside the drill pipe 110 is better balanced.

[0039] In some specific embodiments of the present invention, the drill pipe 110 is provided with an observation port 114, which is provided on the drill pipe 110 and above the equalizing pressure port 113. When the drill pipe 110 is inserted into the human body, the observation port 114 is exposed to the outside of the human body, and the bone tissue in the drill pipe 110 can be observed through the observation port 114. In addition, when the bone tissue is removed from the drill pipe 110, it can also be removed through the observation port 114.

[0040] In some specific embodiments of the present invention, the distance between the observation port 114 and the toothed drill port 111 ranges from 2.5 cm to 4 cm. When the observation port 114 is too far from the toothed drill port 111, it is not conducive to observing the bone tissue in the drill tube 110. When the observation port 114 is too close to the toothed drill port 111, the depth of the drill tube 110 inserted into the human body is limited, thereby limiting the amount of material collected. When the distance between the observation port 114 and the toothed drill port 111 is between 2.5 cm and 4 cm, the effect is best.

[0041] like Figures 2 to 4 As shown, the spinal vertebral biopsy tool assembly according to the second embodiment of the present invention includes a puncture needle 200, a guide rod 300, an expansion tube 400, and a biopsy drill 100 according to the first embodiment of the present invention.

[0042] like Figures 2 to 4 As shown, the puncture needle 200 includes a syringe 210 and a needle core 220, the needle core 220 can be extended into and penetrate the syringe 210, the guide rod 300 can be extended into and penetrate the syringe 210, the expansion tube 400 is a hollow structure, the diameter of the expansion tube 400 is larger than the diameter of the syringe 210, the guide rod 300 can be extended into and penetrate the expansion tube 400, wherein the guide rod 300 can be extended into and penetrate the biopsy drill 100, and the biopsy drill 100 can be extended into and penetrate the expansion tube 400.

[0043] After using the puncture needle 200 to pierce the preset position of the bone tissue, the needle core 220 is removed, and the guide rod 300 is inserted into and penetrated through the syringe 210, and then the syringe 210 is removed, and the expansion tube 400 with a larger diameter is inserted through the guide rod 300 to further expand the opening, and then the biopsy drill 100 is placed in the expansion tube 400 and penetrated through the expansion tube 400 to reach the bone tissue, and the bone tissue is sampled through the biopsy drill 100.

[0044] According to the spinal vertebral biopsy tool assembly of the embodiment of the present invention, by using the biopsy drill 100 of the above embodiment, a tightening recess 112 is provided, so that the internal channel of the drill tube 110 becomes narrower, so that the bone tissue inside the drill tube 110 that has passed through the tightening recess 112 cannot easily slide out of the drill tube 110, thereby increasing the amount of material collected. The spinal vertebral biopsy tool assembly of the embodiment of the present invention can achieve an increase in the amount of material collected by adding a tightening recess 112 to the drill tube 110 provided with a toothed drill opening 111, which is convenient to operate and less traumatic to the patient.

[0045] In some specific embodiments of the present invention, Figure 3 As shown, the guide rod 300 includes a threaded needle 310, which is arranged at one end of the guide rod 300 extending into the syringe 210. By arranging the threaded needle 310, the threaded needle 310 is in close contact with the bone tissue. When taking samples, the guide rod 300 and the biopsy drill 100 are pulled out at the same time, and the threaded needle 310 can assist in pulling the bone tissue and prevent the bone tissue from slipping out of the drill tube 110, thereby increasing the amount of samples taken.

[0046] In some specific embodiments of the present invention, Figure 3 As shown, the guide rod 300 includes a lifting buckle 320, which is arranged at one end of the guide rod 300 and is far away from the threaded needle 310. By pulling out the guide rod 300 through the lifting buckle 320, the operation is more convenient.

[0047] In some specific embodiments of the present invention, a sleeve is also included, and the sleeve is a hollow structure, and the expansion tube 400 can extend into and penetrate the sleeve. According to actual needs, the expansion tube 400 can be replaced with a sleeve with a larger diameter to further expand the opening, thereby making the operation more convenient.
