Description

Technical Field

[0001] The invention belongs to the technical field of bone tumor sampling equipment, and in particular relates to a bone tumor pathological specimen sampling device. Background Art

[0002] Bone tumors are tumors that occur in bones or their appendages. They can be benign or malignant. Benign bone tumors are easily cured and have a good prognosis, while malignant bone tumors develop rapidly, have a poor prognosis, and a high mortality rate. Malignant bone tumors are divided into primary and secondary. Malignant tumors from other tissues or organs in the body that metastasize to the bones through the blood circulation and lymphatic system are secondary malignant bone tumors. There is also a type of lesion called tumor-like lesions. The tissues of tumor-like lesions do not have the characteristics of tumor cell morphology, but their ecology and behavior are destructive to tumors. They are generally more localized and easier to cure. The pathology report of bone tumors needs to be made through bone tumor pathology specimens, so it is necessary to sample the patient's bones.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-7 As shown, a bone tumor pathology specimen collection device comprises a supporting rotating component and a clamping component arranged on the supporting rotating component, the clamping component is used to clamp the human arm and leg, the supporting rotating component is provided with a displacement component, the displacement component is provided with a displacement plate 12 with a circular hole on the upper side, the displacement component can drive the displacement plate 12 to move, a rotating ring 122 is rotatably connected to the circular hole of the displacement plate 12, a plurality of electric telescopic rods 5 arranged in a circular array are rotatably arranged on the upper side of the rotating ring 122, the other end of the electric telescopic rod 5 is elastically rotatably connected to the hanging component, a guide cylinder 3 is vertically arranged at the center of the circular hole, a ball connection ring 31 is ball-connected to the guide cylinder 3, and a connecting seat 32 with the same number as the electric telescopic rod 5 is arranged on the outer edge side of the ball connection ring 31, the connecting seat 32 is rotatably connected to the electric telescopic rod 5 and the hanging component, and the rotatable connection part is located at the same position, that is, if the connecting seat 32, the electric telescopic rod 5 and the hanging component are hingedly connected, they are connected through the same hinge shaft, and the connection through the bearing is also coaxially arranged between the two bearings;

[0033] One or more electric telescopic rods 5 are rotatably connected to the threaded telescopic rods, the threaded telescopic rods are transmitted to the electric telescopic rod 5 and the other end is connected to the electric telescopic rod 3 22, the other end of the electric telescopic rod 3 22 is rotatably connected to the guide cylinder 3, the electric telescopic rod 5 is rotatably connected to the control cylinder 23, an air inlet of the control cylinder 23 is connected to the hanging assembly, a puncture needle 4 is inserted in the guide cylinder 3, and when the output shaft of the control cylinder 23 is extended, the hanging assembly is hung on the puncture needle 4;

[0034] When in use, the person who needs to take specimens puts the leg or arm into the clamping assembly, and the clamping assembly clamps the arm or leg, and then the supporting rotating assembly drives the displacement assembly to rotate, so that the puncture needle 4 rotates to be in the same straight line with the sampling position, and then the displacement assembly drives the displacement plate 12 to move, and the displacement plate 12 drives the puncture needle 4 to align with the sampling position, and then the electric telescopic rod 5 contracts. As the electric telescopic rod 5 contracts, the threaded telescopic rod gradually extends out, so that the guide cylinder 3 is always aligned with the sampling position. During the contraction of the electric telescopic rod 5, the angle between the guide cylinder 3 and the electric telescopic rod 5 gradually increases, and the output shaft of the control cylinder 23 extends out, and the hanging assembly is hung on the puncture needle 4. During the contraction of the electric telescopic rod 5, the puncture needle 4 gradually moves down and pierces the human body. When the sampling position is reached, the person can take samples through the puncture needle 4;

[0035] In order to ensure stable puncture of the puncture needle 4, the puncture needle 4 is rotated by the rotating ring 122 to ensure the puncture of the puncture needle 4;

[0036] When the sampling is completed, the electric telescopic rod 5 is controlled to extend. After the electric telescopic rod 5 is extended, the output shaft of the control cylinder 23 is retracted, and the hanging assembly is no longer hung on the puncture needle 4;

[0037] Among them, when the puncture needle 4 needs to be tilted to puncture the sampling position, the tilt angle of the puncture needle 4 is adjusted by the electric telescopic rod 3 22, and then the support rotation component, displacement component and electric telescopic rod 1 5 are controlled to rotate, displace and adjust the extension of the puncture needle 4 according to the puncture displacement direction required by the puncture needle 4 during puncture to ensure puncture sampling;

[0038] When the electric telescopic rod 3 22 is used for adjustment, since the angle between the guide cylinder 3 and the electric telescopic rod 1 5 changes, at least one hanging component is still hung on the puncture needle 4, and the puncture needle 4 can still be fixed under the action of the hanging component and the guide cylinder 3;

[0039] The upper end of the guide cylinder 3 is provided with a plug hole for placing the upper end of the puncture needle 4. The plug hole prevents the puncture needle 4 from moving further downward through the guide cylinder 3. The guide cylinder 3 is also provided with a vertical hole connected to the plug hole.

[0041] The hook cylinder 43 is connected to the elastic rotation by means of hinge and torsion spring;

[0042] When in use, the hook 42 is used to turn the hook cylinder 43 outward, and then the puncture needle 4 is inserted into the guide cylinder 3, and then the hook 42 is released. Under the action of the torsion spring, the middle part of the hook 42 contacts the pull-down handle 41, and then the control cylinder 23 is stretched, and the hook cylinder 43 drives the hook 42 to move downward until the hook 42 is hooked on the pull-down handle 41;

[0043] When the electric telescopic rod 5 is reset, under the action of the control cylinder 23, the hook cylinder 43 drives the hook 42 to reset, and the personnel can remove the puncture needle 4.

[0044] In the present embodiment, the electric telescopic rod 1 5 is specifically an electric telescopic rod driven by a motor, and its specific structure includes a barrel, a rod body, a threaded rod 52 and a motor. The rod body is inserted in the barrel and cannot rotate. The motor and the threaded rod 52 are transmitted. The threaded rod 52 is threadedly connected to the rod body so that when the motor is driven, the rod body extends or retracts. The motor is a telescopic drive motor 56.
