Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, specifically a probe fixation device in tumor ablation surgery. Background Technology

[0002] During tumor ablation, a probe is inserted into the tumor site. The tip of the probe heats the tumor via microwaves, causing the tumor cells to undergo apoptosis under high temperature.

[0003] When using a probe, it is necessary to ensure precise positioning. However, human breathing and muscle contraction can easily cause the tip of the probe to deviate from the predetermined ablation target area, thus affecting the ablation effect. Nowadays, it is mainly fixed by hand, which increases the workload of medical staff, and it is easy to get tired if they remain still for a long time. Utility Model Content

[0004] To overcome the problem that the puncture probe cannot be fixed to the human body during current tumor ablation procedures, this invention provides a probe fixation device for tumor ablation, which facilitates the fixation of the probe to the human body, allowing the probe head to stably penetrate into the tumor tissue.

[0005] The technical solution is as follows: A probe fixation device for tumor ablation, comprising:

[0006] A fixing base, wherein connecting blocks are provided on both sides of the fixing base, a circular groove is provided at the center of the fixing base, and a through hole is provided at the bottom of the circular groove;

[0007] The fastener has a circular hole with the same size as the through hole in the center, and the upper part of the fastener is forked to form two auxiliary ears, which are elastic.

[0008] The upper part of the screw is a knob that is easy to turn by hand, and the lower outer wall is provided with external threads. At the same time, the center of the screw is provided with an elongated hole of the same size as the through hole.

[0009] The fastener is placed at the bottom of the circular groove, and the upper part of the circular groove is provided with an internal thread that matches the external thread. The screw bolt is installed on the upper part of the fixed seat through the external thread, and the probe passes through the elongated hole, the circular hole, and the through hole in sequence.

[0010] As a preferred embodiment of this utility model, the circular groove is larger at the top and smaller at the bottom, the top of the auxiliary lug is a slope, and the bottom of the elongated hole forms a sloped groove that matches the slope. When the external thread is located above the internal thread, the sloped groove is located above the slope and does not contact it, and the auxiliary lug bends to both sides. When the knob is turned, the external thread moves down, and the sloped groove tightens the bent auxiliary lug. At this time, the sloped groove squeezes the slope, causing the auxiliary lug to clamp the probe.

[0011] As a preferred embodiment of this utility model, the connecting block is provided with holes for installing a connecting strap to fix it to the human body.

[0012] As a preferred embodiment of this utility model, the bottom of the fastener has the same shape and size as the bottom of the circular groove.

[0013] The beneficial effects of this utility model are:

[0014] This device is attached to the human body via a connecting strap. The probe passes through the device and then punctures the body. After the tip of the probe punctures the predetermined position, the knob is rotated to tighten the outer spiral downwards. The inclined groove squeezes the inclined surface of the accessory ear, causing the fastener to clamp the probe, thus fixing the probe in place. Because this device has a simple and compact structure, it can be used on the human body, freeing up the hands of medical staff and ensuring the smooth performance of tumor ablation.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to limit the specific scope of the invention.

[0024] See Figures 1 to 6 The present invention provides a probe fixation device for tumor ablation, comprising:

[0025] The fixing base 1 has connecting blocks 11 on both sides, and a circular groove 12 is formed at the center of the fixing base 1. A through hole 14 is formed at the bottom of the circular groove 12. (See reference) Figure 4 As shown, the fixing base 1 is the outer shell component of this device. The entire device is fixed to the human body by pulling the connecting block 11 with the connecting strap to achieve the fixation of the device.

[0026] Fastener 2, the fastener 2 has a circular hole 23 with the same size as the through hole 14 in the center, and the upper part of the fastener 2 is forked to form two auxiliary ears 21, and the auxiliary ears 21 are elastic;

[0027] The upper part of the screw bolt 3 is a knob 31 that is easy to turn by hand, and the lower outer wall is provided with external thread 32. At the same time, the center of the screw bolt 3 is provided with an elongated hole 33 of the same size as the through hole 14.

[0028] The fastener 2 is placed at the bottom of the circular groove 12. The upper part of the circular groove 12 is provided with an internal thread 13 that matches the external thread 32. The screw bolt 3 is installed on the upper part of the fixing seat 1 through the external thread 32. The probe 4 passes through the elongated hole 33, the circular hole 23, and the through hole 14 in sequence.

[0029] It should be noted that, for reference Figure 1 , Figure 2 , Figure 3 As shown, this device is mainly composed of several parts, including a fixed base 1, a fastener 2, and a screw bolt 3. During installation, the fastener 2 is first placed into the bottom of the circular groove, and then the screw bolt 3 is screwed onto the internal thread 13 through the external thread 32. During use, the probe 4 is passed through the elongated hole 33, the circular hole 23, and the through hole 14 in sequence, and finally punctured into the human body. When fixing, a strap is used to tie it to the human body so that the probe 4 can be fixed to the human body.

[0030] In this embodiment, the circular groove 12 is larger at the top and smaller at the bottom. The top of the auxiliary lug 21 is a slope 22, and the bottom of the elongated hole 33 forms a sloped groove 34 that matches the slope 22. When the external thread 32 is located above the internal thread 13, the sloped groove 34 is located above the slope 22 and does not contact it. The auxiliary lug 21 bends to both sides. When the knob 31 is turned, the external thread 32 moves down, and the sloped groove 34 tightens the bent auxiliary lug 21. At this time, the sloped groove 34 squeezes the slope 22 so that the auxiliary lug 21 clamps the probe 4.

[0031] In this embodiment, the connecting block 11 has a hole 15 for installing a connecting strap to fix it to the human body.

[0032] In this embodiment, the bottom of the fastener 2 has the same shape and size as the bottom of the circular groove 12.

[0033] It should be noted that this device is attached to the human body via a connecting strap. The probe 4 passes through the device and then punctures the human body. After the tip of the probe 4 punctures the predetermined position, the knob 31 is rotated, causing the outer screw 32 to tighten downwards. The inclined groove 34 presses against the inclined surface 22 of the accessory ear 21, causing the fastener 2 to clamp the probe 4. This achieves the fixation of the probe 4. Because this device has a simple and compact structure, it can be used on the human body, thereby freeing the hands of medical staff and ensuring the smooth performance of tumor ablation.
