Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a thyroid puncture positioning frame. Background Art

[0002] Thyroid puncture is a procedure used to diagnose nodular thyroid disease. It is often used for certain thyroid conditions that remain difficult to diagnose after multiple tests. It is a routine test for goiter and thyroid nodules, helping to understand the pathology of the disease, ultimately confirming the diagnosis and guiding treatment. During this procedure, a fine needle is inserted into the thyroid lesion to extract a small amount of tissue. The cells are then examined under a microscope to determine their properties and make a diagnosis.

[0003] During the puncture operation, an ultrasonic detector is needed to locate the affected area. The ultrasonic positioning and puncture work cannot be completed by one person. It requires the assistance of other operators or two operators to perform it at the same time. The operation is inconvenient and wastes medical resources. In addition, the puncture angle cannot be fixed during the puncture process. During the puncture with a handheld puncture needle, the puncture angle is prone to deviation, which may increase the trauma to the patient's neck skin and muscles at the least, and endanger the patient's safety at the worst.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] As attached Figure 1 and attached Figure 2 As shown, a thyroid puncture positioning frame includes two groups of curved rods 1, and support frames 2 are respectively connected between the ends of the two groups of curved rods 1. The support frames 2 are L-shaped structures, and the two groups of support frames 2 are respectively connected to the sides away from each other with anti-slip patches 3. A positioning block 4 is slidably sleeved on the outer side of the curved rod 1, and a puncture needle catheter 5 passes through the middle of the positioning block 4;

[0026] The positioning block 4 is provided with two sets of arc-shaped guide holes 6 for the arc-shaped rod 1 to pass through, and the two ends of the arc-shaped guide holes 6 are provided with clamping positioning mechanisms 7 for the arc-shaped rod 1:

[0027] Through the above structure, the puncture point is determined according to the position of the thyroid affected part, and the two groups of support frames 2 are placed on the outside of the patient's neck, so that the axis of the puncture needle catheter 5 is aligned with the puncture point, and the lower side of the support frame 2 is in contact with the neck. The overall position of the positioning frame is adjusted according to the puncture point, and the clamping and positioning mechanism 7 releases the clamping of the arc rod 1, and the positioning block 4 is slid on the outside of the arc rod 1. The inclination angle of the puncture needle catheter 5 is adjusted according to the puncture point. The clamping and positioning mechanism 7 cooperates with the arc guide hole 6 to clamp the outside of the arc rod 1, limit the positioning block 4, and stick it to the neck through the anti-slip patch 3 to keep the support frame 2 stable on the outside of the patient's neck. The medical staff can observe the thyroid affected part by adjusting the position of the ultrasonic probe with one hand, and puncture through the puncture needle catheter 5 into the patient's thyroid affected part for sampling with the other hand. No other operator assistance is required. The specific structure is as follows:

[0028] Combined with attachment Figure 3 and attached Figure 4 As shown, the clamping and positioning mechanism 7 includes a mounting groove 701 connected to the arc-shaped guide hole 6. The mounting groove 701 is located between the two groups of arc-shaped rods 1. A clamping block 702 that matches the arc-shaped rod 1 is slidably installed inside the mounting groove 701.

[0029] Multiple groups of springs 703 are connected between the side of the clamping block 702 away from the arc rod 1 and the bottom of the installation groove 701, and a push rod 705 is installed on the other side of the clamping block 702. The other end of the push rod 705 slides out of the positioning block 4, and a push plate 706 is connected between the ends of the multiple groups of push rods 705 located on the same side of the positioning block 4. The side of the clamping block 702 close to the arc rod 1 is provided with an arc groove 704 that fits with the arc rod 1.

[0030] Through the above structure, when the positioning block 4 needs to slide on the outside of the arc rod 1, the clamping positioning mechanism 7 needs to release the clamping of the arc rod 1, and the thumb and index finger respectively press the push plates 706 on both sides of the positioning block 4, and squeeze the push plates 706 toward the positioning block 4. The push plates 706 and the push rods 705 push the clamping block 702 to move inside the mounting groove 701. The multiple groups of springs 703 are squeezed and compressed by the clamping block 702, and the clamping block 702 moves away from the arc rod 1. The arc groove 704 does not contact the arc rod 1. At this time, the arc rod 1 can slide between the arc guide hole 6 and the arc groove 704, and the positioning block 4 is adjusted on the outside of the arc rod 1.

[0031] After the position of the positioning block 4 is determined, the push plate 706 is released, and the clamping block 702 is moved toward the arc rod 1 and contacts the arc rod 1 through the rebound force of the spring 703. The friction coefficient of the inner wall of the arc groove 704 is large, and the arc groove 704 and the arc guide hole 6 are clamped on the outside of the arc rod 1 to achieve the positioning of the positioning block 4.

[0032] Combined with attachment Figure 3 As shown, the push plate 706 is an arc-shaped structure, and the lower arc surface of the push plate 706 is located above the lower arc surface of the positioning block 4.

[0033] Through the above structure, in order to facilitate the adjustment of the position of the ultrasonic detection head, the lower side of the positioning block 4 is at a distance from the patient's neck, and the push plate 706 is set to an arc structure and the lower side height is higher than the lower side height of the positioning block 4, so the push plate 706 will not affect the ultrasonic detection head.
