In order to better realize the fixation of the whole device, two sides of the attaching belt 1 are respectively connected with a fixing belt 18, and the whole device can be well fixed on a patient body through the fixing belts 18, so that the fixation is firm.
When the invention is used specifically, when a puncture operation is needed, firstly, the adhesive tape 1 is adjusted in angle according to the puncture position, the adhesive tape 1 is rotated to the most adhesive angle on the body surface of a patient through rotation, the clamping joint 4 in the middle of the adhesive tape 1 is arranged at the position needing puncture, when the puncture operation is not carried out, an adjusting device can not be added, when the puncture operation is needed, the adjusting device is arranged on the adhesive tape 1, and the specific operation is as follows: the threaded pipe joint 13 is connected with the clamping joint 4 through threads, in an initial state, the adjusting sleeve 11 is arranged at the highest position, the supporting plate 5 is located at the highest point under the action of the first spring 6, the push rod 10 is located at the highest point under the action of the second spring 14, the clamping block 9 is located at the outermost side under the action of the third spring 15, the centers of the top plate 12 of the adjusting sleeve 11, the movable barrel 8, the supporting plate 5 and the bottom plate 2 of the fixed barrel 3 on the adjusting device are communicated up and down, and the puncturing device can be inserted into the center.
In the specific operation process, whether to start the adjustment function is determined according to the requirement, and the specific adjustment process is as follows: firstly, by screwing the adjusting sleeve 11, the adjusting sleeve 11 is in threaded connection with the fixed cylinder 3, the adjusting nut 16 on the outer edge of the adjusting sleeve 11 can be conveniently used, during screwing, the adjusting sleeve 11 first pushes the push rod 10 to move downwards through the top plate 12, so that the second spring 14 is compressed, since the compression coefficient of the second spring 14 is much smaller than that of the first spring 6, the second spring 14 will be compressed to the final state first, and during the downward movement of the push rod 10, under the action of the third spring 15, the push rod 10 is always contacted with the inclined surface part of the clamping block 9, meanwhile, the adjusting sleeve 11 can simultaneously drive the three push rods 10 to synchronously move downwards and push the three clamping blocks 9 to synchronously slide inwards, and finally the three clamping blocks 9 clamp the puncture device, and the clamping effect on the puncture device can be well realized by the internal arc structural design of the clamping blocks 9 and the design of the elastic layer 17 on the inner side; after clamping, at the moment, the adjusting sleeve 11 is continuously screwed, the adjusting sleeve 11 can continuously move downwards, because the push rod 10 is compressed to the limit, the adjusting sleeve 11 can drive the movable cylinder 8 to integrally move downwards at the moment, which is equivalent to driving the puncture device to move downwards through screwing at the moment, because the outer side wall of the movable cylinder 8 and the outer side wall of the fixed cylinder 3 are respectively provided with the convex block and the vertical groove 7, when the movable cylinder 8 is installed in the fixed cylinder 3, the convex block is embedded in the vertical groove 7, so that the movable cylinder 8 cannot rotate along with the adjusting sleeve 11 and can only move upwards and downwards, and the movement is more stable; simultaneously, the adjusting effect through the threads can accurately control the inserting depth and be convenient for calculating the integral inserting depth, and the fine adjustment can be accurately carried out at the late stage of puncture, so that the accuracy is high.
When the puncture device needs to be fixed in position after puncture is completed, the adjusting sleeve 11 can be screwed upwards, the puncture device can be loosened by the clamping block 9 through reverse action of the upward adjusting process in the process of upward adjustment, the whole adjusting device is taken down after the puncture device is completely loosened, the adhesive tape 1 cannot move at the moment, the puncture device can be fixed by the adhesive tape 1 through medical adhesive tapes or other fixtures, the fixing bands 18 on two sides can be arranged on the adhesive tape 1, the fixing bands 18 can be circumferentially wound on the body of a patient, the fixing is firm at the moment, and the puncture position cannot be easily changed.
According to the invention, by designing the adjusting device capable of guiding and positioning puncture, in the adjusting process, through actions of clamping firstly and puncturing secondly, the insertion is more stable in the puncture process, especially when a diseased region is reached soon at the end of a puncture operation, accurate fine adjustment can be carried out through the adjusting device, damage to other parts caused by too deep insertion is avoided, and meanwhile, as the whole device realizes the puncture action by adopting thread screwing, the fixity of the puncture direction can be effectively maintained, and the danger caused by artificial shaking is avoided; in addition, the quick-connection and quick-disassembly threaded joint is convenient to use, can be used for adjustment in the early stage and can be used as an accessory in the later stage, and meanwhile, if secondary puncture is needed, under the action of the adhesive tape 1, the positions of two times can be conveniently unified, and repeated damage is avoided.
Meanwhile, the device is directly fixed on the body of a patient and keeps relatively static with the patient, so that the problem of accuracy of the puncture part caused by unconscious shaking of the patient is avoided.
The invention has novel conception and smart structure, can well realize the guiding and positioning of the puncture device, can well assist the accurate puncture and measure the puncture depth, and greatly improves the puncture quality and efficiency.
