Description

Technical Field

[0001] The present invention relates to the technical field of medical orthopedic sampling, in particular to an orthopedic sampling device for medical examination. Background Art

[0002] The principle of conventional trephine drilling for vertebral bone removal is as follows: after establishing a good working channel through pedicle puncture, the trephine is rotated forward through the working channel and drilled 1-1.5 cm. At this point, a cylindrical bone segment is contained within the trephine, the distal end of which is connected to other bone within the vertebral body. In cases of normal vertebral bone density, due to the high friction between the bone within the trephine and the inner wall of the trephine, rapid withdrawal of the trephine can generally sever the distal end of the cylindrical bone, thereby removing the bone. However, clinical practice has found that in some patients with osteoporosis and severe vertebral damage, the bone is pathologically damaged and loose, resulting in reduced friction between the bone and the inner wall of the trephine. Therefore, the friction generated by the trephine withdrawal is insufficient to sever the bone sample, making it impossible to remove the bone fragment for pathological examination.

[0003] The medical orthopedic sampling trephine, published as CN105852914B, comprises a drill rod with a drill bit at its lower end and a handle at its upper end. The drill rod is a cylindrical structure, the upper end of which is rotatably connected to the center of the handle. An outer sleeve is fitted over the drill rod, with the outer wall of the drill rod and the inner wall of the outer sleeve engaged by a splined mechanism that allows axial sliding. A sleeve handle is fixedly connected to the upper end of the outer sleeve, with a clutch mechanism provided between the sleeve handle and the handle. The drill bit is composed of at least two circularly arranged arcuate plates, the outer surfaces of which are provided with inclined surfaces that gradually converge inward from bottom to top. This medical orthopedic sampling trephine has a simple structure and is easy to use. It can clamp bone samples during sampling, improving the success rate of sampling.

[0004] The above technical solution is not convenient for efficient sampling operations, and is also not convenient for rapid removal and placement of vertebral bone after sampling, so it needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an orthopedic sampling device for medical examination.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An orthopedic sampling device for medical examination, comprising a mounting tube, a linkage mechanism provided at the top of the mounting tube, a lead screw and a synchronization tube provided on the linkage mechanism, a power mechanism provided on the synchronization tube, a lead screw nut tube and a first synchronization wheel provided on the power mechanism, a lifting mechanism provided on the lead screw nut tube, a lead screw provided on the lifting mechanism, and a driving mechanism provided on the first synchronization wheel; A control handle is installed on one side of the upper end of the installation pipe; The driving mechanism is provided with a connecting shaft, the lower end of the connecting shaft is detachably connected to a sampling assembly, a moving tooth assembly is installed in the sampling assembly, an extrusion mechanism is provided in the sampling assembly, a circular plate is provided on the extrusion mechanism, and the upper end of the moving tooth assembly and the upper end of the circular plate are rotatably connected to an inclined rod.

[0007] Compared with the prior art, the present application can realize automated operation, making it easier for the sampling assembly to rotate and lift for sampling operations. At the same time, the tooth assembly can be moved to effectively contact and clamp the bone sample, and the bone sample can be quickly removed from the sampling assembly. At the same time, the rotation speed of the sampling assembly can be effectively adjusted as needed to ensure the quality and efficiency of bone sample sampling.

A pressure rod is penetrated in the threaded hole, and the lower end of the pressure rod extends into the sampling component. The pressure rod is connected to the extrusion mechanism, and a fastening bolt is penetrated on one side of the connecting shaft. One end of the fastening bolt penetrates the threaded hole and abuts against the upper end of the pressure rod.

[0009] Furthermore, during actual production and preparation, a groove is provided at the lower end of the connecting shaft, which can effectively correspond to the cylinder at the upper end of the sampling assembly. The sampling assembly consists of a thin-walled circular tube and a cylinder fixed on the thin-walled circular tube. The cylinder can be inserted into the groove at the lower end of the connecting shaft. At the same time, a fastening bolt is provided through the connecting shaft, and the fastening bolt can be screwed into the threaded hole to complete the connection and fixation of the sampling assembly and the connecting shaft. Moreover, the diameter of the sampling assembly is greater than or equal to the diameter of the connecting shaft to ensure the connection effect. When the fastening bolt passes through the threaded hole, the fastening bolt will contact the upper end of the pressure rod so that the pressure rod can descend and push the circular plate to descend.

[0010] Preferably, the squeezing mechanism comprises a tension spring member fixed to the top of the sampling assembly, and the lower end of the tension spring member is fixed to the upper end of the circular plate member.

[0011] Furthermore, when the circular plate descends, the circular plate drives the movable tooth assembly to move toward the interior of the sampling assembly through the inclined rod. The teeth on the movable tooth assembly are tilted upward, making it easier for the teeth to clamp the bone sample during sampling, thereby ensuring the stability of the bone sample in the sampling assembly. At the same time, after the sampling is completed, the fastening bolt can be removed from the threaded hole part, and the circular plate part can be pulled up by the action of the tension spring part. The rise of the circular plate part can enable the inclined pull rod to push the moving tooth assembly into the side wall of the sampling assembly, so that the bone sample can be removed from the sampling assembly.

[0013] Furthermore, during actual production and preparation, the vertical shaft component is composed of two wheel bodies and a belt component adapted to the wheel bodies. The belt is mounted on the two wheel bodies. At the same time, tooth structures are provided on the wheel bodies and the belts to ensure effective engagement and complete stable power transmission. The vertical shaft component can drive the screw component to rotate, thereby providing power for the operation of the lifting mechanism and helping to increase the moving speed of the sampling component.

[0014] Preferably, the power mechanism includes a motor mounting frame rotatably sleeved on a synchronous pipe fitting, a motor assembly is mounted on the motor mounting frame, the output shaft of the motor assembly is fixedly connected to the first synchronous wheel, and a screw nut pipe fitting is rotatably sleeved on one side of the motor mounting frame.

[0015] Furthermore, during actual production and preparation, the stability of the position of the motor assembly can be achieved through the action of the motor mounting bracket, so that the power of the motor assembly can be stably output. The motor assembly can drive the first synchronous wheel to rotate, and the rotation of the first synchronous wheel can provide power for the lifting operation, and can also provide power for the operation of the driving mechanism.

[0017] Furthermore, the vertical axis can be rotated by the rotation of the synchronous pipe, and the vertical axis can drive the screw to rotate through the linkage belt assembly. The screw and the screw linkage can cooperate to make the screw linkage and the lifting member rise and fall. At the same time, the screw linkage will not rotate, but the screw nut pipe can be rotated under the action of the first synchronous wheel, the second synchronous wheel and the synchronous belt, which can make the screw nut pipe rise and fall relative to the screw linkage, that is, the two-stage rapid movement of the screw nut pipe can be realized, and the two-stage rapid lifting of the screw nut pipe can make the sampling assembly quickly correspond to the sampling position.

[0018] Preferably, the driving mechanism includes two second synchronous wheels fixed to the screw nut tube and the synchronous tube, the first synchronous wheel is located between the two second synchronous wheels, and a synchronous belt is commonly sleeved on the first synchronous wheel and the two second synchronous wheels.

[0019] Furthermore, the diameter of the first synchronous wheel is larger than the diameter of the second synchronous wheel to ensure that the synchronous belt can correspond to the first synchronous wheel and the second synchronous wheel, which facilitates stable power transmission. The speed change mechanism can control the rotation speed of the sampling component as needed, thereby improving sampling efficiency.

[0020] Preferably, the speed change mechanism includes an electric telescopic rod fixed to the lower end of the mounting frame, the lower end of the mounting frame is rotatably sleeved with a first pulley, the lower end of the first synchronous pulley is fixed with a second pulley of a linkage belt, the support shaft is rotatably sleeved with the lower end of the second pulley, the second pulley and the first pulley are jointly sleeved with a linkage belt, the electric telescopic rod is arranged through the linkage belt, and the lower end of the second pulley is provided with an adaptation mechanism; The adapting mechanism is provided with a first tapered linkage roller; A second tapered linkage roller is fixed to the lower end of the first pulley, and the second tapered linkage roller is in conflict with the first tapered linkage roller; The adapting mechanism is connected to the supporting shaft.

[0021] Furthermore, the extension and retraction of the electric telescopic rod can cause the sliding plate to squeeze the extrusion plate, so that the interference position of the first conical linkage roller and the second conical linkage roller changes. When the interference position changes, the time for the second conical linkage roller to rotate one circle remains unchanged, but the rotational linear speed at different positions changes. The different interference positions of the first conical linkage roller and the second conical linkage roller will cause the rotational speed of the first conical linkage roller to change, that is, the rotational speed of the support shaft can be adjusted as needed to achieve the purpose of adjusting the rotational speed of the sampling component.

[0022] Preferably, the adaptation mechanism includes a connecting plate rotatably sleeved on the support shaft, an elastic telescopic rod is installed on one side of the connecting plate, the elastic telescopic rod is connected to the extrusion plate, a sliding plate is slidably mounted on the extrusion plate, the piston rod end of the electric telescopic rod is fixed to the upper end of the sliding plate, a tensioning mechanism is provided on one side of the connecting plate, the tensioning mechanism, the lower end of the extrusion plate and the support shaft are all provided with rotating wheels, and a rotating belt is commonly sleeved on the three rotating wheels; The first tapered linkage roller is fixed to the lower end of one of the rotating wheels; One of the rotating wheels is rotatably sleeved on the lower end of the extruded plate, and the other rotating wheel is fixedly sleeved on the supporting shaft.

[0023] Furthermore, the elastic telescopic rod can be used to adjust the distance between the extrusion plate and the connecting plate as needed, and the sliding plate can ensure the movement of the extrusion plate. By allowing the extrusion plate to move, the first tapered linkage roller and the second tapered linkage roller can be brought into contact with each other at different positions. Furthermore, the elastic telescopic rod can fully ensure the effect of the contact between the first tapered linkage roller and the second tapered linkage roller, ensuring that the first tapered linkage roller and the second tapered linkage roller can transmit the power through friction. During actual production and preparation, corresponding friction patterns are set on the first tapered linkage roller and the second tapered linkage roller as needed to ensure the friction effect; Furthermore, the elastic coefficient of the elastic telescopic rod is controlled to ensure that the first tapered linkage roller can fully contact the second tapered linkage roller.

[0024] Preferably, the tensioning mechanism includes a transverse axis fixed on one side of the connecting plate, a sliding shaft is slidably sleeved on the transverse axis, a spring member is sleeved on the transverse axis, two ends of the spring member are respectively fixed on the sliding shaft and the transverse axis, and a third rotating wheel is rotatably sleeved on the sliding shaft.

[0025] Furthermore, during actual production and preparation, the spring part can pull the sliding shaft to move in a direction away from the connecting plate, that is, when the extrusion plate moves toward the connecting plate, the sliding shaft will drive the rotating wheel at its lower end to move in a direction away from the connecting plate, so as to ensure that the rotating belt is fully tensioned and that power can be transmitted.

[0026] The beneficial effects of the present invention are: 1. During the actual production and preparation of the components in this application, tooth structures are provided on the wheel body components and belt components used therein to ensure that the teeth on the belt and the teeth on the wheel body can mesh and facilitate transmission. In addition, the diameter specifications between the wheel bodies are controlled to ensure that the wheel body and the belt can fully contact each other to ensure stable output and transmission of power. 2. Corresponding control components are provided on the control handle to control the operation of the automated components within the device, thereby controlling the position and rotation speed of the sampling assembly for sampling operations. Furthermore, a battery assembly or a power connection assembly may be provided within the control handle as required to ensure stable operation of the automated components. The control and circuit connections of the automated components are all based on existing technologies. 3. In this device, a two-stage lifting mechanism can be realized by connecting the screw member, the screw linkage member, the screw nut pipe member and the supporting components to increase the lifting speed of the sampling assembly, that is, the screw member is arranged in a screw structure, and a screw nut structure corresponding to the screw member is arranged inside the screw linkage member. At the same time, the outer side of the screw linkage member is also in a screw structure, and a screw nut structure corresponding to the outer side of the screw linkage member is arranged inside the screw nut pipe member; that is, the screw member rotates, and the screw linkage member cannot rotate under the action of the lifting member, and the screw member can control the lifting and lowering of the screw linkage member. At the same time, the rotation of the screw nut pipe member can also make the screw nut pipe member rise and fall relative to the screw linkage member, and control the structures on the screw member, the screw linkage member and the screw nut pipe member to ensure that the screw nut pipe member also falls when the screw linkage member falls; 4. The position of the first tapered linkage roller and the second tapered linkage roller in contact with each other changes. When the position of the contact changes, the time it takes for the second tapered linkage roller to rotate one circle remains unchanged, but the linear speed of rotation at different positions changes. The different positions of the first tapered linkage roller and the second tapered linkage roller in contact with each other will cause the rotation speed of the first tapered linkage roller to change. That is, the rotation speed of the support shaft can be adjusted as needed to achieve the purpose of adjusting the rotation speed of the sampling component. 5. When the circular plate descends, it can drive the movable tooth assembly toward the interior of the sampling assembly through the inclined rod. The teeth on the movable tooth assembly are tilted upward, making it easier for the teeth to clamp the bone sample during sampling, thereby ensuring the stability of the bone sample in the sampling assembly. At the same time, after the sampling is completed, the fastening bolt can be removed from the threaded hole part, and the circular plate part can be pulled up by the action of the tension spring part. The rise of the circular plate part can enable the inclined pull rod to push the moving tooth assembly into the side wall of the sampling assembly, so that the bone sample can be removed from the sampling assembly.
