Description

Technical Field

[0001] The present invention relates to the technical field of surgical probes, and in particular to a probe fixing device used in tumor ablation. Background Art

[0002] In tumor ablation, the probe fixation device plays a vital role. The main function of this device is to ensure that the probe can be stably and accurately placed in the target tumor tissue during the operation, thereby ensuring the maximum ablation effect; However, since this type of fixation device is fixed by spring force, during the fixation process, the spring force will act on the probe when the spring fixes the probe, causing it to shake. Since this type of probe is inserted into the human body, this shaking may cause the probe to move accidentally in the human body, causing the probe to be inserted into the large blood vessels or organs around the tumor, thereby causing damage to the human body. In addition, this type of probe is manually inserted into the human body by a doctor. When inserting the probe, the doctor needs to accurately control the force and speed to avoid causing unnecessary damage to the patient. Excessive force or excessive speed may cause complications such as tissue tearing or blood vessel rupture. This operation requires the doctor to have extremely high control to complete, and its operation is relatively difficult. Therefore, it does not meet the existing needs. In this regard, we propose a probe fixing device for tumor ablation. Summary of the invention

[0037] In this embodiment, the fixing member includes a plurality of top bars arranged on the matching grabbing head 204 e , and a buffer pad is arranged on the upper end of the top bar, and the buffer pad is in contact with the outer wall of the probe member 206 .

[0038] Preferably, a sliding member 300 is provided on the main body block 202 .

[0039] In this embodiment, the sliding member 300 includes a first motor 301 arranged on the main block 202, a first driving wheel 302 arranged on the motor shaft of the first motor 301, a second driving wheel 303 arranged on the main block 202, and a driving belt 304 arranged between the first driving wheel 302 and the second driving wheel 303. The driving belt 304 is arranged along the length direction of the main block 202, and the second driving wheel 303 is arranged away from the first driving wheel 302. A rotating groove 400 connected to the driving belt 304 is opened on the slide plate 204a, and the support rod 204b extends outward through the first rotating cylinder 203a.

[0040] A slot is provided on the side wall of the support rod 204b, and a key 306 is slidably connected in the slot. A spring steel ball is provided at the notch of the slot. A key slot cooperating with the key 306 is provided on the first rotating cylinder 203a. The operator can press the key 306 to pop the key 306 outward. After popping out, the key 306 is matched with the key slot, and then the first extension member 203 and the second extension member 204 are matched and fixed, so that they can rotate together, and at the same time, the sliding of the second extension member 204 will not be hindered. When the operator presses the key 306 into the slot, the key 306 no longer cooperates with the key slot, and the sliding of the first extension member 203 and the second extension member 204 are no longer synchronized.

[0041] During surgery, the operator uses the driving motor to drive the first rotating cylinder 203a to rotate as needed. At this time, the key 306 and the key slot are in a matched state. At this time, the first rotating cylinder 203a will synchronously drive the second frame rod 204c to rotate. Then the operator adjusts the sliding of the slide plate 204a to push the second frame rod 204c outward. After pushing out, the distance between the first frame rod 203b and the second frame rod 204c will be adjusted. When the second frame rod 204c is closer to the bottom, the end of the second frame rod 204c will be closer to the probe member 206, thereby fixing the end of the probe member 206.

[0042] When the key 306 is in the keyway non-matching state, the support rod 204b can be rotated at will, and when the first rotating cylinder 203a rotates, the support rod 204b will not be driven to rotate synchronously. Because the grabbing head 205 and the matching grabbing head 204e can be rotated, the operator can first stagger the positions of the first frame rod 203b and the second frame rod 204c, and then the operator can respectively rotate the grabbing head 205 and the matching grabbing head 204e, and then the probe piece 206 can be inserted obliquely, so as to select different angles for surgery.

[0043] Furthermore, the present invention also includes a rotating assembly, which is arranged on the grab head 205. The rotating assembly includes a rotating groove 400 arranged on the grab head 205, a first gear 401 rotatably connected in the rotating groove 400, a clamping groove 402 is provided on the grab head 205, a second gear 403 meshing with the first gear 401 is rotatably connected in the clamping groove 402, a matching hole 404 matching with the probe member 206 is provided in the center of the first gear 401, an internal thread sleeve 405 is provided on the matching hole 404, and an external thread matching with the thread sleeve is provided on the side wall of the probe member 206.

[0044] Preferably, when tying the cable tie 406b, the operator inserts the cable tie 406b into the end of the rotary groove 400 and then pulls it out from the other end of the rotary groove 400. During the pulling process of the cable tie 406b, several protruding teeth on the surface of the cable tie 406b will engage with the second gear 403, thereby driving the second gear 403 to rotate.

[0045] In this embodiment, the driving member 406 includes a first rotating wheel 406a rotatably connected to the grabbing head 205, and a rolling belt 406b arranged between the first rotating wheel 406a and the rotary groove 400. Engaging gear teeth engaging with the second gear 403 are arranged on the outer side of the rolling belt 406b. The rolling belt 406b is an open rolling belt 406b, which is divided into two ends. Soft plug rods and soft plug holes are respectively arranged on the two ends of the rolling belt 406b, and the soft plug rods are plugged into the soft plug holes.

[0046] Preferably, both ends of the rotary groove 400 are outwardly connected to the grab head 205 to form a first opening and a second opening, and a bevel member 500 is arranged at the connection between the slot 402 and the rotary groove 400. In the present embodiment, the bevel member 500 includes a track changing block 501 which is slidably connected in the rotary groove 400 in the vertical direction, and bevel blocks 502 are arranged near the first opening and the second opening of the track changing block 501, the bevels of the two bevel blocks 502 are arranged opposite to each other, and an arc block 503 is arranged at the end of the track changing block 501 away from the second gear 403. When observed from above, the shape of the groove surrounded by the two bevel blocks 502 and the arc block 503 is an arc shape, and the top end of the arc is just close to the second gear 403.

[0047] A supplementary block 504 is also provided on the inner upper surface of the rotary groove 400, and a guide rail 505 is provided in the rotary groove 400. The guide rail 505 is arranged around the buffer column, and both ends of the guide rail 505 are connected to the rotary groove 400. When the track changing block 501 slides upward, the supplementary block 504 blocks the groove surrounded by the two inclined blocks 502 and the arc block 503, leaving only two arc channels, and the two arc channels are connected to the two ends of the guide rail 505.

[0048] Operation process; the whole device has two usage modes: 1. Up and down movement mode: the operator slides the track changing block 501 upward, and at this time the operator inserts the cable tie into the rotating groove 400. When the cable tie is inserted, the cable tie is guided by the shape of the groove surrounded by the two inclined blocks 502 and the arc block 503, so that the cable tie is close to the second gear 403, and then the protrusion drives the second gear 403 to rotate, and then drives the rotation of the internal thread sleeve 405, and the cooperation of the internal thread and the external thread makes the probe Part 206 moves up and down; 2. Fixed connection mode: the operator moves the track changing block 501 upward, so that the supplementary block 504 blocks the groove surrounded by the two inclined blocks 502 and the arc block 503, and the two remaining arc channels are connected to the guide rail 505. At this time, when the operator inserts the cable tie, the cable tie will extend along the direction of the guide rail 505 and pass out from the opening at the other end of the guide rail 505. At this time, the rolling belt 406b surrounds the probe part 206, which will further fix the probe part 206.

[0049] The two connection methods allow for changes based on different usage scenarios, thereby increasing the application scenarios of this device.
