Description

Technical Field

[0001] The utility model relates to the technical field of CT scanning, in particular to a sample clamp used for CT scanning and a CT scanner. Background Art

[0002] When performing a CT scan, it is usually necessary to place the sample in a sample tube that comes with the CT scanner. After being placed in the sample tube, the sample needs to remain suspended upright to facilitate scanning. To this end, the existing technology usually fills scraps of cloth between the sample tube and the sample. Although this method can keep the sample suspended upright, it takes a lot of time to fill the scraps of cloth before scanning, and it is not convenient to remove the sample from the sample tube after scanning. That is, the loading and unloading of the sample in the sample tube is inconvenient and takes a long time. The loading and unloading efficiency is low, which leads to low scanning efficiency of the sample. In addition, after the sample is taken out of the sample tube, the discarded scraps of cloth will also form a lot of garbage, which easily causes material waste and is not environmentally friendly.

[0034] Refer to Figures 1 to 4, an embodiment of the present utility model provides a sample clamp for CT scanning, which includes a clamping member 100, a mounting member 200, and a hand-held portion 220. The clamping member 100 is arranged in a ring shape, and the inner end of the clamping member 100 is elastic and forms a clamping space 130 for the sample 400 to pass through. The lower end of the mounting member 200 is connected to the clamping member 100 and is arranged circumferentially around the clamping member 100, and the mounting member 200 extends outward in the upward direction. The hand-held portion 220 is provided on the mounting member 200 and protrudes in the direction close to the central axis of the clamping member 100. Among them, the mounting member 200 is elastic, so that the upper end of the mounting member 200 can move and converge in the direction close to the central axis of the clamping member 100 under the action of an external force.

[0035] By using the sample clamp of the embodiment of the present utility model, when it is necessary to place the sample 400 into the sample tube 300 for CT scanning, the sample 400 can be placed in the clamping space 130 of the clamping member 100. Since the inner end of the clamping member 100 is elastic, the sample 400 can be stably clamped. After the sample 400 is fixed, the operator can pick up the mounting member 200 through the hand-held portion 220 and insert the entire clamping member 100 into the sample tube 300. During this process, since the mounting member 200 is elastic, the upper end of the mounting member 200 can move and converge in the direction close to the central axis of the clamping member 100 under the extrusion of the inner peripheral wall of the sample tube 300, so that the upper end of the mounting member 200 can be in contact with the inner peripheral wall of the sample tube 300 to fix the clamping member 100 in the accommodation cavity 310. Since the lower end of the mounting member 200 is connected to the clamping member 100 and the mounting member 200 extends outward in the upward direction, the clamping member 100 can be suspended inside the sample tube 300. When the sample 400 needs to be taken out after the scanning is completed, the operator can take out the entire clamp from the sample tube 300 only through the hand-held portion 220, and the operation is convenient and simple. It can be seen that the sample clamp of the embodiment of the present utility model can very conveniently realize the loading and unloading of the sample 400 in the sample tube 300, without consuming too much time, the loading and unloading efficiency of the sample 400 is relatively high, and no garbage is generated during the whole process, which is more environmentally friendly.

[0036] Refer to Figures 1 to 4 , in some embodiments, the clamping member 100 includes a connecting portion 110 and an elastic portion. The connecting portion 110 is arranged in a ring shape. The elastic portion is connected to the connecting portion 110 and is arranged circumferentially around the connecting portion 110. The elastic portion extends in the direction close to the central axis of the connecting portion 110 and forms a clamping space 130.

[0037] By adopting the above structure, the outer end of the elastic part is connected to the connecting part 110 and arranged circumferentially around the connecting part 110, and the inner end of the elastic part encloses and defines a clamping space 130. Thus, when it is necessary to place the sample 400 into the sample tube 300 for CT scanning, the sample 400 can be placed in the clamping space 130 at the inner end of the elastic part, and the elastic part can deform and stably clamp the sample 400. After clamping the sample 400, the operator can pick up the mounting part 200 through the holding part 220 and insert the entire clamping part 100 into the sample tube 300. The operation is convenient and simple, without consuming too much time, the loading and unloading efficiency of the sample 400 is relatively high, and the sample 400 can be clamped more stably at the same time.

[0038] Referring to Figures 1 to 4 , in some embodiments, the elastic part is inclined towards the central axis of the connecting part 110 in the up-down direction.

[0039] By adopting the above structure, the elastic part is inclined towards the central axis of the connecting part 110 in the up-down direction, so that the elastic part has a tapered structure with a larger upper part and a smaller lower part. Furthermore, the elastic part can guide the sample 400 to be inserted into the clamping space 130 from top to bottom during the process of the sample 400 being inserted into the clamping space 130. Thus, not only can the sample 400 be clamped conveniently, the operation is more simple and convenient, which is beneficial to improving the loading and unloading efficiency of the sample 400, but also the inner end of the elastic part can better clamp the sample 400.

[0040] Referring to Figures 1 to 4 , in some embodiments, the elastic part includes eight elastic strips 120. The elastic strips 120 are connected to the connecting part 110 and are inclined towards the central axis of the connecting part 110 in the up-down direction. All the elastic strips 120 are arranged at intervals circumferentially around the connecting part 110, and the lower ends of all the elastic strips 120 are arranged at intervals and enclose to form the clamping space 130.

[0041] By adopting the above structure, the elastic part is arranged in a structure where eight elastic strips 120 are arranged at intervals circumferentially around the connecting part 110, which can not only save the production materials of the elastic part and reduce the production and processing cost of the sample fixture, but also facilitate the insertion of the sample 400 into the clamping space 130.

[0042] It can be understood that the above elastic part includes eight elastic strips 120, which is only for Figures 1 to 4An exemplary description does not represent a specific limitation of the present utility model. The elastic part may include, in addition to eight elastic strips 120, two, three, four, five, six, seven, nine or more elastic strips 120. The present utility model does not make specific limitations on this, as long as the elastic part includes at least two elastic strips 120. In some embodiments, all the elastic strips 120 are arranged at intervals along the circumferential direction of the connecting part 110. Specifically, all the elastic strips 120 can be evenly arranged along the circumferential direction of the connecting part 110, so that the sample 400 can be clamped more stably and balancedly. It can be understood that when the elastic part includes two elastic strips 120, the two elastic strips 120 can be arranged oppositely, so that the sample 400 can be clamped more stably and balancedly.

[0043] It can be understood that the elastic part can not only be set as a structure in which at least two elastic strips 120 are arranged at intervals along the circumferential direction of the mounting part. In some embodiments, the elastic part can also be set as an elastic ring arranged along the circumferential direction of the mounting part. The present utility model does not make specific limitations on this.

[0044] It can be understood that the clamping member 100 includes a connecting part 110 and an elastic part connected to each other. Specifically, the connecting part 110 and the elastic part can be connected by a fastening structure or a clamping structure, or the connecting part 110 and the elastic part can also be connected by connection methods such as welding and bonding. In addition to the above structures, in some embodiments, the connecting part 110 and the elastic part can also be set as an integral structure. The present utility model does not make specific limitations on this.

[0045] In some embodiments, the mounting member 200 includes two oppositely arranged mounting rods 210. The mounting rods 210 are connected to the clamping member 100 and extend outward in the upward direction. The upper ends of the two mounting rods 210 can move relatively close to each other under the action of an external force. The holding part 220 is arranged on one of the mounting rods 210 and protrudes toward the central axis of the clamping member 100.

[0046] By adopting the above structure, the mounting member 200 includes two oppositely arranged mounting rods 210. The mounting rods 210 are connected to the clamping member 100 and extend outward in the upward direction. Thus, when the fixture is inserted into the sample tube 300, the upper-large and lower-small conical structure formed by the two mounting rods 210 can guide the two mounting rods 210 to be smoothly inserted into the sample tube 300 from top to bottom. In addition, the upper ends of the two mounting rods 210 can move relatively closer and converge under the extrusion of the inner wall of the sample tube 300, so that the upper ends of the mounting rods 210 can abut against the inner peripheral wall of the sample tube 300 to fix the clamping member 100 in the accommodating cavity 310. When the sample 400 needs to be taken out after the scanning is completed, the operator can take out the entire fixture from the sample tube 300 only through the holding parts 220 on the mounting rods 210, and the operation is convenient and simple. It can be seen that the sample fixture of the embodiment of the present utility model can very conveniently realize the loading and unloading of the sample 400 in the sample tube 300, without consuming too much time, the loading and unloading efficiency of the sample 400 is relatively high, and no garbage is generated during the whole process, which is more environmentally friendly.

[0047] Referring to Figures 1 to 4 , in some embodiments, the number of the holding parts 220 is also two. The two holding parts 220 are connected to the two mounting rods 210 in one-to-one correspondence, and the two holding parts 220 are oppositely arranged.

[0048] By adopting the above structure, a holding part 220 is arranged on each mounting rod 210, so that the loading and unloading of the fixture can be more convenient.

[0049] It can be understood that the holding part 220 and the mounting rod 210 can be connected by a fastening structure or a clamping structure, or the holding part 220 and the mounting rod 210 can also be connected by connection methods such as welding and bonding. In addition to adopting the above structure, in some embodiments, the holding part 220 and the mounting rod 210 can also be set as an integral structure, and the present utility model does not make specific limitations on this.

[0050] It can be understood that, in some embodiments, the holding part 220 can also adopt a hollow annular structure, so that it is more convenient to take the fixture.

[0051] Referring to Figures 1 to 4 , in some embodiments, the mounting rod 210 is specifically an elastic rod.

[0052] By adopting the above structure, the mounting rod 210 is configured as an elastic rod. When the sample 400 needs to be placed in the sample tube 300 for CT scanning, the sample 400 can be clamped by the clamping member 100. The operator can then pick up the mounting member 200 using the handheld portion 220 and insert the entire clamping member 100 into the sample tube 300. During this process, due to the elasticity of the mounting rod 210, the upper end of the mounting rod 210 can be moved and retracted in a direction close to the central axis of the clamping member 100 under the pressure of the inner circumferential wall of the sample tube 300, thereby causing the upper end of the mounting rod 210 to abut against the inner circumferential wall of the sample tube 300, thereby fixing the clamping member 100 in the accommodating cavity 310. Because the lower end of the mounting rod 210 is connected to the clamping member 100 and the mounting rod 210 is arranged outwardly in a bottom-to-top direction, the clamping member 100 can be placed in the sample tube 300 in a suspended manner. When the sample 400 is scanned and needs to be removed, the operator simply removes the entire fixture from the sample tube 300 using the handle 220, making the operation convenient and simple. Thus, the sample fixture of the present invention embodiment can easily and efficiently load and unload the sample 400 from the sample tube 300 without wasting too much time. Furthermore, the entire process does not generate any waste, making it environmentally friendly.

[0053] In some structures, in addition to directly setting the mounting rod 210 as an elastic rod, in some embodiments, the lower end of the mounting rod 210 can also be rotatably connected to the clamping member 100, and an elastic member is provided between the mounting rod 210 and the clamping member 100.

[0054] By adopting the above structure, during the process of inserting the mounting member 200 into the sample tube 300, since an elastic member is provided between the mounting rod 210 and the clamping member 100, the upper end of the mounting rod 210 can rotate in a direction close to the central axis of the clamping member 100 and retract against each other under the squeezing action of the inner circumferential wall of the sample tube 300. At this time, the elastic member contracts, thereby allowing the upper end of the mounting rod 210 and the inner circumferential wall of the sample tube 300 to abut against each other, thereby fixing the clamping member 100 more firmly and stably in the accommodating cavity 310.

[0055] It is understandable that the elastic member may specifically be a compression spring or a torsion spring, etc., and the present invention does not make any specific limitation on this.

[0056] Reference Figures 1 to 4 In some embodiments, the clamping member 100 , the mounting member 200 , and the hand-held portion 220 are all non-metallic parts.

[0057] By adopting the above structure, the clamping member 100, the mounting member 200 and the handheld portion 220 are all configured as non-metallic parts, thereby facilitating CT scanning of structures such as bone joints.

[0058] It can be understood that the clamping member 100, the mounting member 200 and the handheld portion 220 may specifically be made of plastic parts or other non-metallic parts, and the present utility model does not make specific limitations thereto.

[0059] An embodiment of the present utility model further provides a CT scanner, which includes a sample tube 300 and the sample clamp for CT scanning according to any one of the above embodiments. Among them, the sample tube 300 has a receiving cavity 310 for receiving a sample 400. When the mounting member 200 and the clamping member 100 are inserted into the receiving cavity 310, the upper end of the mounting member 200 can move along the direction close to the central axis of the clamping member 100 and abut against the inner peripheral wall of the receiving cavity 310, and there is a spaced arrangement between the clamping member 100 and the inner peripheral wall of the receiving cavity 310.

[0060] In the CT scanner according to the embodiment of the present utility model, by adopting the sample clamp for CT scanning according to any one of the above embodiments, when it is necessary to place the sample 400 into the sample tube 300 for CT scanning, the sample 400 can be stably clamped by the clamping portion of the sample clamp, and the sample clamp can be stably mounted in the receiving cavity 310 of the sample tube 300 through the mounting portion of the sample clamp, and the clamping portion is suspended in the receiving cavity 310, so that the sample 400 can be suspended in the receiving cavity 310, which is beneficial to the smooth progress of CT scanning. When the sample 400 needs to be taken out after the scanning is completed, the operator only needs to take out the entire clamp from the sample tube 300 through the handheld portion 220, and the operation is convenient and simple.

[0061] Specifically, the sample clamp includes a clamping member 100, a mounting member 200 and a hand-held portion 220. The inner end of the clamping member 100 is elastic and forms a clamping space 130 for the sample 400 to pass through. The lower end of the mounting member 200 is connected to the clamping member 100 and is arranged to extend outward in the upward direction. The mounting member 200 is elastic, so that the upper end of the mounting member 200 can move and converge in the direction close to the central axis of the clamping member 100 under the action of an external force. Thus, when it is necessary to place the sample 400 into the sample tube 300 for CT scanning, the sample 400 can be placed in the clamping space 130 of the clamping member 100. Since the inner end of the clamping member 100 is elastic, the sample 400 can be stably clamped. After the sample 400 is fixed, the operator can pick up the mounting member 200 through the hand-held portion 220 and insert the entire clamping member 100 into the accommodating cavity 310 of the sample tube 300. During this process, since the mounting member 200 is elastic, the upper end of the mounting member 200 can move and converge in the direction close to the central axis of the clamping member 100 under the extrusion of the inner peripheral wall of the accommodating cavity 310, so that the upper end of the mounting member 200 can abut against the inner peripheral wall of the sample tube 300, thereby fixing the clamping member 100 in the accommodating cavity 310. Since the lower end of the mounting member 200 is connected to the clamping member 100 and the mounting member 200 is arranged to extend outward in the upward direction, the clamping member 100 can be suspended in the accommodating cavity 310. When the sample 400 needs to be taken out after the CT scanning is completed, the operator can take out the entire clamp from the sample tube 300 only through the hand-held portion 220, and the operation is convenient and simple. It can be seen that the CT scanner according to the embodiment of the present invention can very conveniently load and unload the sample 400 and perform CT scanning, can greatly shorten the loading and unloading time of the sample 400, and is thus beneficial to improving the scanning efficiency of the sample 400. Moreover, no garbage is generated before and after the CT scanning, which is more environmentally friendly.

[0062] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
