Problems solved by technology

However, the cyst is not a clear liquid, but has a certain viscosity, and its moving speed in the needle is slow. When the syringe structure sucks the sample, the tightness of the connection between the injection tube and the push rod is limited, and "seeing only pushing" often occurs. The rod moves, and the sample is not sucked out.” It is necessary to repeatedly push and pull the push rod to suck out the sample, but when the needle is pushed toward the needle, the cyst sample that has entered the needle may be pushed out of the needle again, causing the sample to spread in the body. If it is a malignant cyst, it is likely to cause metastasis
Chinese patent CN96119633.5 discloses a multifunctional medical suction device, which realizes negative pressure suction sampling by setting a negative pressure device, avoiding the problem of repeatedly pushing and pulling the push rod of the syringe, but the negative pressure device needs to consume electric energy to work, which is not conducive to energy saving

Embodiment 1

[0037] An energy-saving puncture and suction device for thyroid cysts, see Figure 1-4 , including a fixing sleeve 1, which is used to be fixed on the patient's neck. The fixed sleeve 1 is a rigid sleeve. The rigid sleeve is a circular sleeve formed by splicing two arc-shaped plates. One end of the two arc-shaped plates is hinged by a rotating shaft or a hinge, and the other end is detachably connected by a lock. A fixing hole 11 is opened on the plate; or, the fixing sleeve 1 is an elastic sleeve made of a flexible material, which includes two sections of elastic belts, and one end of the two sections of elastic belts is connected by a mounting seat with a fixing hole 11, and the two sections The other ends of the elastic bands are detachably connected by lock buckles.

[0038] A puncture aspirator is detachably installed in the fixed hole 11, and the puncture aspirator includes a needle 2, an outer cylinder 3, a slide plate 4, a movable ball 5, a fixed handle 6, a movable h...

Embodiment 2

[0048] An energy-saving puncture and suction device for thyroid cyst, which has basically the same structure as that of Example 1, the difference is that, see Figure 5-7 :

[0049] The movable ball 5 of the present embodiment is an elastic ball, and the diameter of the elastic ball in the natural state is greater than the length of the reset assembly in the natural state, and when the reset assembly is in the natural state, the slide plate 4 contacts the movable ball 5, and makes the movable ball 5 When deformation occurs, the movable ball 5 can partially enter the inside of the needle 2; when the slide plate 4 moves away from the movable ball 5, the movable ball 5 returns to its original shape and leaves the connection between the needle 2 and the outer tube 3.

[0050] When the inner diameter of the needle 2 is between 2-4mm, a wrapping assembly for wrapping the cyst sample is inserted inside it, and the wrapping assembly includes a wrapping head 9, which adopts a flexible ...

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to an energy-saving thyroid cyst puncture suction device. The device comprises a fixing sleeve, a fixing hole is formed in the fixing sleeve, and a puncture suction device is detachably installed in the fixing hole. The puncture suction device comprises a needle head, an outer cylinder, a sliding plate, a movable ball, a fixed handle, a movable handle and a reset assembly. A magnetic component is arranged in the sliding plate, and a magnet which is in mutual magnetic attraction with the magnetic component is arranged on the movable handle; a one-way air valve is further arranged on the cylinder wall of the outer cylinder and located between the front end of the inner wall of the outer cylinder and the sliding plate. By repeatedly moving the movable handle, negative pressure is continuously applied to the needle head, finally, a cyst sample is sucked out, electric negative pressure equipment is not needed in the whole process, electric energy is not consumed, and the device is energy-saving and small in operation difficulty.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an energy-saving puncture and suction device for thyroid cyst. Background technique [0002] Thyroid cyst refers to a sac containing fluid found in the thyroid gland. It is located near the neck of the patient. The mass is round, with a diameter of 2-5 cm. It is smooth, generally painless or slightly painful, and moves up and down with swallowing. In order to diagnose the pathological nature of cysts, samples are usually drawn by puncture for detection. The supporting medical devices include puncture needles, puncture devices, etc. [0003] In the prior art, the puncture device used for sampling mainly includes a needle for piercing the affected area, and a tail handle for fixing the needle. The tail handle adopts a suction balloon structure, and the needle is changed by squeezing the suction balloon The air pressure in the needle, and then the sample is s...
