Detailed Description

The utility model will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model. Further, it will be understood that various changes or modifications may be made by those skilled in the art after reading the teachings of the utility model, and such equivalents are intended to fall within the scope of the utility model as defined herein.

The utility model relates to an ablation needle fixing device, which comprises a main body structure, a fixing core 2 and a sucker 7. The shell 1 is the hollow cylinder in inside, and is equipped with round hole 3 on the bottom surface of shell 1, and the diameter of round hole 3 is greater than the diameter of ablation needle, can guarantee that the ablation needle runs through round hole 3 to shell 1 is rigid plastic, and the deformation is little, can play the fixed infirm phenomenon of fixing when the ablation needle can not appear. And be equipped with the through-hole on the fixed core 2, the through-hole on the fixed core 2 sets up with the round hole 3 on the shell 1 coaxial, ensures that the ablation needle can run through the through-hole on the fixed core 2 and the round hole 3 on the shell 1. The fixed core 2 and the shell 1 are detachably connected, however, the fixed core 2 and the shell 1 can be in shaft hole clamping connection or threaded connection. The threaded connection is selected here, because the threaded connection is convenient in the process of disassembling the device after the ablation needle is used up, one end of the fixed core 2, which is far away from the shell 1, is provided with a plurality of stop blocks 9, the rotation of the fixed core 2 can be better realized, the number of the stop blocks 9 is at least two, the stable rotation of the fixed core 2 can be kept, and the number of the stop blocks 9 selected here is two. The fixed core 2 is provided with the separation groove 4, and the separation groove 4 separates the through holes, so that the through holes can be used for clamping the ablation needle when the fixed core 2 is connected with the shell 1. In contrast, since the partition groove 4 partitions only a part of the through holes, the through holes partitioned by the partition groove 4 are referred to as first through holes 5, and the through holes not partitioned by the partition groove 4 are referred to as second through holes 6. The through hole for clamping the ablation needle is mainly the first through hole 5.

Embodiment one:

the fixed core 2 is cylindrical, can realize threaded connection with the inner hole of the shell 1, and the fixed core 2 is made of soft plastic material, and can realize deformation. Therefore, the diameter of the first through hole 5 is smaller than that of the ablation needle, so that the ablation needle can realize deformation of the fixed core 2 when penetrating through the fixed core 2, and the part of the fixed core 2 divided by the separation groove 4 deforms to the periphery to achieve a conical state. The fixed core 2 is connected with the shell 1 through threads, so that the first through hole 5 is clamped with the ablation needle. The size of the second through hole 6 is the same as that of the round hole 3 on the shell 1, and the function of the second through hole 6 mainly plays a role of being penetrated by an ablation needle.

Embodiment two:

the fixed core 2 is round table-shaped, can realize threaded connection with the inner hole of the shell 1, and the fixed core 2 is made of soft plastic material, and can realize deformation. The diameter of the first through hole 5 on the fixed core 2 is the same as the diameter of the ablation needle, so that the ablation needle can penetrate through the fixed core 2, and the fixation of the fixed core 2 to the ablation needle is realized. The length at the two ends of the separation groove 4 on the fixed core 2 is smaller than the diameter inside the shell 1, so that when the ablation needle is fixed, the fixed core 2 can be rotated into the shell 1, and the fixed core 2 is made of soft plastic materials, so that the trend of compression from the periphery to the middle can be realized at the position of the first through hole 5, and the clamping and fixing of the ablation needle by the first through hole 5 can be realized.

Embodiment III:

the fixed core 2 is divided into a conical section and a cylindrical section, the first through hole 5 is positioned in the conical section of the fixed core 2, and the second through hole 6 is positioned in the cylindrical section of the fixed core 2. The material of the fixed core 2 is soft plastic material, and can realize deformation. As described in the second embodiment, if the fixed core 2 has only a tapered section, the operation is inconvenient when the fixed core 2 and the housing 1 are mounted together, and a case occurs in which the aperture of the first through hole 5 is smaller than the diameter of the ablation needle, so that the ablation needle cannot pass through the fixed core 2. A cylindrical section is provided below the conical section of the stationary core 2, and the cylindrical section functions to facilitate the mounting and fixing of the stationary core 2. And the length of both ends of the partition groove 4 on the fixed core 2 is smaller than the diameter of the inside of the housing 1. The conical section of the fixed core 2 can not generate the situation that the fixed core 2 is clamped on the inner diameter of the shell 1 when the ablation needle is fixed, and the fixation of the ablation needle can not be realized. And because the fixed core 2 is made of soft plastic materials, the conical section of the fixed core 2 is deformed, and then the ablation needle is clamped and fixed.

According to the embodiment, the sucker 7 is arranged on the outer side of the shell 1, the sucker 7 is provided with a limiting hole 8, and the limiting hole 8 is connected with the shell 1. The limiting holes 8 have the function of fixedly supporting the shell 1, so that the problem that the shell 1 cannot be fixed and inclines to the periphery due to unbalance of the skin surface of the body is prevented. The arc-shaped section on the sucker 7 plays a role of fixing the sucker 7, so that the sucker 7 is fixed on the skin. The fixed core is made of soft plastic material, namely plastic which can be compressed and deformed and can return to the original state, the soft plastic is PE, PP, PS, PVC, PC and the like, and the thread is required to be arranged on the outer side of the fixed core, so that the PVC plastic material commonly used in medicine is selected.

The use method is as follows:

the fixing core 2 is connected with the shell 1, and the sucking disc 7 is fixed with the shell 1, and the sucking disc 7 is not needed for some gentle parts of the body, or the sucking disc 7 is not fixed with the shell 1. The assembled device is put on the ablation needle, and the ablation needle only releases heat, so that the aging of the device caused by too high temperature is not worried. In performing the treatment, the device is first mounted to the side of the ablation needle remote from the needle tip (as shown in fig. 7 of the drawings), and the ablation needle is then inserted into the body. When the ablation needle reaches the ablation site, the device is lowered from the side distal from the tip of the ablation needle so that the device contacts the skin. With the suction cup 7 in the device, it is also necessary to fix the device to the skin surface with the suction cup 7. After the device is fixed, the stop block 9 on the fixed core 2 needs to be rotated, so that the ablation needle is fixed by the first through hole 5 of the fixed core 2. And after the treatment is completed, the stop block 9 on the fixed core 2 is rotated to release the ablation needle fixed by the first through hole 5. The suction cup 7 is then released again so that the entire device is slid again to the side remote from the tip of the ablation needle, which is then withdrawn from the body. After the tip of the ablation needle is cooled, the whole device is taken down from the ablation needle, and the device is disassembled.

In summary, the device solves the problem of finger ache caused by the hand holding of the ablation needle in the traditional Chinese medicine growing time in the treatment process, and solves the problem of the deviation of the ablation needle caused by palm replacement of a doctor in the treatment process, thereby affecting blood vessels, nerves and the like. And the device also prevents the problem of misalignment of the ablation needle during treatment due to unconditional reflection by the patient. The damage to the patient caused by the ablation needle during the treatment process is reduced.
