[0002] Bone tumors are tumors that originate in bone tissue. Their nature, type, and degree of malignancy have a decisive impact on a patient's treatment plan and prognosis. Accurately obtaining bone tumor pathological tissue samples is a prerequisite for clarifying the tumor's pathological characteristics through microscopic observation, immunohistochemistry, and other testing methods. This provides an important basis for clinicians to formulate personalized treatment strategies. Pathological tissue sampling is an indispensable and critical step, whether distinguishing benign from malignant tumors or assessing the tumor's invasiveness and metastatic potential. Currently, existing bone tumor pathology tissue sampling devices generally lack an integrated cutting function. In practice, the sampling and cutting processes are often separated.

[0020] Furthermore, both the left shell 1 and the right shell 2 include a handle 9 disposed at the bottom. A control switch 10 is snap-connected to the inner wall of the handle 9 , and the control switch 10 is connected to the micro motor 31 via a wire.

[0021] By setting the control switch 10 to control the start and stop of the micro motor 31 , when a doctor is sampling bone tumor pathological tissue, the doctor can touch the control switch 10 with his fingers by holding the handle 9 , thereby facilitating the quick start and stop of the micro motor 31 .

[0022] Furthermore, a charging port is provided at the bottom end of the handle 9, and the charging port is connected to the battery 11 through a wire, and the battery 11 is connected to the micro motor 31 through a wire, and the micro motor 31 is a DC motor.

[0023] The battery 11 can provide electric energy to the micro motor 31 , and the charging port can charge the battery 11 . The micro motor 31 is a DC motor that can directly utilize the electric energy provided by the battery 11 .

[0024] Furthermore, a guide rod 12 is fixedly connected to the inner top surface of the right shell 2, and a slide groove 314 and a guide groove 315 are penetrated through the upper surface of the cross-shaped connecting rod 36. The slide groove 314 slides in contact with the pulley 35, and the guide groove 315 slides in contact with the guide rod 12. A half-side guide sleeve 316 is fixedly connected to the inner wall of the left shell 1 and the right shell 2.

[0025] When the micro motor 31 is started, it can drive the coupling 32 to rotate, and the coupling 32 drives the rotating rod 33 to rotate, and the rotating rod 33 drives the turntable 34 at its top to rotate, and the turntable 34 drives the pulley 35 to rotate around the axis of the rotating rod 33. Since the pulley 35 slides in the slide groove 314, when the pulley 35 rotates around the axis of the rotating rod 33, it can drive the slide groove 314 to reciprocate, and then drive the cross-shaped connecting rod 36 to reciprocate. After the left shell 1 and the right shell 2 are docked and merged, the two half-side guide sleeves 316 meet and come into sliding contact with the cross-shaped connecting rod 36. At the same time, with the cooperation of the guide rod 12 and the guide groove 315, the cross-shaped connecting rod 36 can stably perform linear reciprocating motion.

[0026] Furthermore, a plug is fixedly connected to the inner wall of the left shell 1 and the right shell 2 , a shaft rod 311 is inserted between the two plugs, and the connecting rod 312 is in sliding contact with the inside of the sleeve 6 .

[0027] Furthermore, a rotating rod 33 is fixedly connected to the center of the bottom surface of the turntable 34, and a bearing is sleeved on the outer surface of the rotating rod 33. The outer ring of the bearing is embedded with an axis plate 13. Two axis plates 13 are provided, one of which is fixedly connected to the inner wall of the left shell 1, and the other axis plate 13 is fixedly connected to the inner wall of the right shell 2.

[0028] After the micro motor 31 is started, the cross connecting rod 36 can be driven to perform linear reciprocating motion. At this time, the cross connecting rod 36 drives the connecting ear 1 37, the connecting ear 1 37 drives the connecting ear 2 38, and the connecting ear 2 38 drives the arc strip 39. The arc strip 39 drives the arc groove 310 to swing with the shaft 311 as the support point under the limiting guidance of the shaft 311, and then drives the cutting blade 313 to perform reciprocating arc swing inside the sleeve 6 through the connecting rod 312. In this way, both the upper and lower sides of the cutting blade 313 and the front end of the cutting blade 313 can cut the bone tissue. In this way, the bone tissue can be cut from multiple directions at the same time, the cutting contact area is increased, the cutting efficiency is improved, and the cutting requirements at different angles can be adapted, making the cutting process more flexible, facilitating more accurate and comprehensive cutting of the bone tissue, and creating good conditions for subsequent tumor tissue sampling.

[0029] Furthermore, the upper end, lower end and front end of the cutting blade 313 are all provided with micro-serrated grooves, the thickness of the cutting blade 313 is 1-1.5 mm, and two circular holes are opened through the outer surface of the cutting blade 313, and the outer surface of the cutting blade 313 is coated with a nano-scale diamond coating, and the thickness of the nano-scale diamond coating is 0.5-1 μm.

[0030] The two circular holes opened on the outer surface of the cutting blade 313 are used to pass screws, which makes it convenient to use screws to connect the cutting blade 313 to the connecting rod 312. The outer surface of the cutting blade 313 is coated with a nano-scale diamond coating, which can significantly improve its hardness and wear resistance, reduce wear and loss during the cutting process, and extend its service life.

[0031] Furthermore, two ear blocks 7 and two side blocks 8 are fixedly connected to the side wall of the sleeve 6, and the two ear blocks 7 are internally rotatably connected to the vertical shaft 42. One end of the torsion spring 48 abuts against the outer wall of the sleeve 6, and the other end of the torsion spring 48 abuts against the inner wall of the bite block 41.

[0032] Furthermore, a portion of a thin rope 44 is wound around the outer surface of the micro capstan 43 , a second sliding wheel 46 is rotatably connected between the two side blocks 8 , and a first sliding wheel 45 is rotatably connected to the outer wall of the sleeve 6 .

[0033] Furthermore, a hand plate 47 is hinged on the outer wall of the right shell 2, and the thin rope 44 is made of ultra-high molecular weight polyethylene fiber material, and the diameter of the thin rope 44 is 0.8-1.2 mm.

[0034] When the bone tissue is cut, the tumor pathological tissue in the bone tissue is exposed. The cutting blade 313 is stopped by stopping the micro motor 31. At this time, the hand plate 47 can be pulled to pull the thin rope 44. The thin rope 44 will drive the micro capstan 43 to rotate with the assistance of the No. 1 sliding wheel 45 and the No. 2 sliding wheel 46. The micro capstan 43 drives the vertical shaft 42 to rotate. The vertical shaft 42 overcomes the torsion of the torsion spring 48 and drives the bite block 41. In this way, the bite block 41 can rotate around the axial direction of the vertical shaft 42. In this way, when the bite block 41 gradually approaches the side of the cutting blade 313, the cutting blade 313 cooperates with the bite block 41 to bite the tumor pathological tissue. Since there is a sawtooth on the side of the bite block 41, the tumor pathological tissue can be easily sampled. The overall structure combines the sampling and cutting functions, which is convenient for simplifying the sampling process and improving efficiency.

[0035] When in use, first, the doctor shakes the handle 9 and touches the control switch 10 with his finger, and the DC micro motor 31 is powered by the battery 11. After pressing the control switch 10, the micro motor 31 is started; then, the micro motor 31 drives the coupling 32, the rotating rod 33, and the turntable 34 to rotate, and the turntable 34 drives the pulley 35 to rotate, and the pulley 35 slides in the slide groove 314 of the cross-shaped connecting rod 36. At the same time, the guide rod 12 slides in the guide groove 315 and cooperates with the half-side guide sleeve 316 to make the cross-shaped connecting rod 36 stably perform linear reciprocating motion, thereby driving the ear 1 37, the ear 2 38, and the arc strip 39 to move. The arc strip 39 is limited in the guide groove 311 of the shaft rod. The micro motor 31 is stopped when the bone tissue is cut and the tumor pathological tissue is exposed. Then, the thin rope 44 is pulled by pulling the hand plate 47. The thin rope 44 drives the micro capstan 43 and the vertical shaft 42 to rotate with the assistance of the first sliding wheel 45 and the second sliding wheel 46. The vertical shaft 42 overcomes the torsion force of the torsion spring 48 and causes the bite block 41 to rotate around the vertical shaft 42 close to the cutting blade 313. The two cooperate to use the side serrations of the bite block 41 to bite and take the tumor pathological tissue.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
