Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a positioning transmitter with adjustable puncture needle angle. Background Art

[0002] With the rapid development of radiological technology, CT-guided percutaneous lung puncture biopsy has been gradually applied in clinical practice. Due to its minimally invasive and easy operation, it has become one of the important means of diagnosis and differential diagnosis of lung masses. Its diagnostic accuracy is high, so it is increasingly used in clinical practice. At present, the accuracy of clinical puncture mainly depends on the experience of doctors. Under the guidance of CT, it may be necessary to adjust the puncture angle several times to reach the center of the tumor and complete the sampling. However, the process of adjusting the puncture angle several times will inevitably increase the damage to the organ tissues, and in severe cases, complications such as massive bleeding may occur.

[0003] The patent with the existing patent announcement number CN 215018649 U records a precise positioning angle puncture device, wherein the puncture device recorded therein includes an angle meter, a damping shaft, a puncture needle channel and a micro laser emitter. The angle meter is a semicircular structure, and an angle scale is engraved on its side edge. A through hole is opened at the bottom center of the angle meter, and one end of the damping shaft is clamped in the through hole and is rotatably connected to the angle meter. The other end of the damping shaft is vertically fixedly connected to one side of the bottom of the puncture needle channel. The puncture needle channel is a hollow structure with openings at the bottom and the top. A micro laser emitter is fixedly installed on the top of the side facing the angle meter, which plays a role in auxiliary puncture positioning of puncture biopsy of pulmonary nodules. The structure is simple, the operability is strong, and the angle positioning is more accurate. However, the puncture device does not have a vertical reference system. When adjusting the angle, deviation is likely to occur, resulting in a large puncture positioning error. In addition, no fixing mechanism is provided, which makes the operation inconvenient and reduces the accuracy of puncture.

[0004] Based on this, a positioning transmitter with adjustable puncture needle angle is now provided to eliminate the drawbacks of the existing devices. Utility Model Content

[0028] In one embodiment, Figure 1 As shown, the inclinometer 200 is a semicircular structure, and a scale 201 is engraved on the side edge of the inclinometer 200. The measuring range of the inclinometer 200 is 0 to 180 degrees, and the scale 201 is accurate to 0.1 degree.

[0029] In one embodiment, Figure 2 As shown, the reference mechanism includes a vertical reference component 205, a connecting rope 206, and a plumb bob 207. The vertical reference component 205 is provided at the bottom of the inclinometer 200. The bottom of the vertical reference component 205 is connected to the connecting rope 206. The end of the connecting rope 206 is connected to the plumb bob 207. A center marking line is provided on the surface of the vertical reference component 205. The center marking line and the plumb bob 207 are used to facilitate adjusting the vertical reference component 205 to a vertical position, thereby more accurately measuring the insertion angle of the puncture needle.

[0030] In one embodiment, Figure 3-Figure 4 As shown, the rotating mechanism includes a rotating block 300, a baffle 301, and a handpiece 306. The baffle 301 is provided on the top of the frame 100 on the back of the inclinometer 200. The end of the rotating shaft 202 is rotatably connected to the side wall of the baffle 301. The rotating block 300 is fixed on the rotating shaft 202. The end of the rotating block 300 is provided with a handpiece 306. The rotating block 300 is rotated through the handpiece 306, thereby driving the rotating shaft 202 to rotate. The rotating shaft 202 drives the puncture needle channel 203 to rotate to achieve angle adjustment. The side wall of the rotating block 300 is provided with a fixing mechanism for fixing its position.

[0031] In one embodiment, Figure 3-Figure 4As shown, the fixing mechanism includes a knob 302, a locking rod 303, and a limiting groove 304.

The laser emitted by the laser emitter 204 is projected onto the scale 201 of the inclinometer 200 to adjust the angle.

[0035] Working principle: When in use, the center mark line and the plumb bob 207 are used to adjust the vertical reference component 205 to a vertical position, so as to more accurately measure the insertion angle of the puncture needle. The rotating block 300 is rotated through the handpiece 306, thereby driving the rotating shaft 202 to rotate, and the rotating shaft 202 drives the puncture needle channel 203 to rotate, and then the laser emitted by the laser emitter 204 on the side wall of the end of the puncture needle channel 203 is projected onto the scale 201 of the angle meter 200 to adjust the angle. When the angle adjustment is completed, the knob 302 is rotated to make the end of the locking rod 303 press and contact with the bottom of the limiting groove 304 to fix the position, and then the puncture needle is inserted from the puncture needle channel 203 into the nodule in the skin. At this time, the insertion point on the puncture needle channel, the puncture point on the skin and the nodule under the skin form a three-point straight line, and the angle positioning is more accurate, which helps to relieve the patient's pain. It is simple and convenient to make, has strong practicality, and is suitable for clinical promotion.
