Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without any inventive effort, are intended to be within the scope of the utility model.

Example 1:

referring to fig. 1 to 3, a thyropuncture device comprises a body 1. Specifically, the barrel 1 is of a hollow columnar structure, and one end of the barrel 1 is provided with a mounting head 11 communicated with the inside of the barrel 1.

The mounting head 11 has a cylindrical structure, and the mounting head 11 is provided with a tip penetration portion 2. Specifically, the tip puncture part 2 is a puncture needle, one end of the puncture needle is a spike end capable of penetrating into an affected part of thyroid gland, and the other end is a tubular structure matched with the mounting head 11. The tubular structure of the puncture needle is sleeved on the mounting head 11 and is in threaded connection with the mounting head 11. The puncture needle head in threaded connection is more convenient to detach from the mounting head 11 of the barrel body 1, and the puncture needle head is convenient to replace.

Referring to fig. 2 and 4, a negative pressure extraction mechanism is provided in the barrel 1, and includes a piston head 3. Specifically, the piston head 3 is a rubber head adapted to the barrel 1, and the piston head 3 is disposed in the barrel 1 through the stopper assembly 4 and is capable of sliding in the barrel 1 along the length direction of the barrel 1.

The limiting assembly 4 comprises a limiting groove 41 formed on the inner wall of the barrel 1 and a limiting ball 42 fixed on the side wall of the piston head 3. The limiting groove 41 is a hemispherical long groove body in cross section, and the length direction of the limiting groove 41 is parallel to the length direction of the barrel body 1. The two limiting grooves 41 are formed, and the two limiting grooves 41 are arranged on the inner wall of the cylinder body 1 in a central symmetry mode relative to the axial central axis of the cylinder body 1.

The limiting ball 42 is a rubber ball fixed on the side wall of the piston head 3, the position of the limiting ball 42 on the piston head 3 is matched with the limiting groove 41, and the limiting ball 42 is inserted into the corresponding limiting groove 41 and abuts against the groove wall of the limiting groove 41. Under the action of the limiting ball 42 and the limiting groove 41, the piston head 3 can slide in the cylinder body 1 along the cylinder body 1, and meanwhile, the piston tightly abuts against the inner wall of the cylinder body 1 when sliding in the cylinder body 1, so that the tightness between the piston head 3 and the cylinder body 1 is ensured.

An adjusting screw 5 extending to the outside of the barrel 1 is fixed to the side of the piston head 3 away from the tip penetration portion 2. Specifically, the adjusting screw 5 is disposed in parallel with the barrel 1.

Further, referring to fig. 2 and 5, an end of the barrel 1 remote from the tip penetration portion 2 is rotatably provided with an adjustment cover 6 capable of controlling movement of the adjustment screw 5 within the barrel 1. Specifically, the adjustment cover 6 is a cylindrical cover body, a rotation limiting ring 61 made of rubber is fixed on an inner cylinder surface of the adjustment cover 6, and the rotation limiting ring 61 is close to a cover opening of the adjustment cover 6 on an inner side wall of the adjustment cover 6. A rotary ring groove 62 matched with the rotary limiting ring 61 is formed on the outer side wall of the barrel body 1, and the rotary ring groove 62 is far away from the tip puncture part 2 on the barrel body 1. The rotation limiting ring 61 of the adjustment cover 6 is sleeved on the rotation ring groove 62 of the cylinder body 1, so that the rotation connection between the adjustment cover 6 and the cylinder body 1 is realized.

When adjusting closing cap 6 is pulled out towards the direction of keeping away from stack shell 1, the rotation restriction ring 61 of the rubber material on adjusting closing cap 6 can take place certain deformation, and then can break away from and rotate annular 62, and then realize adjusting closing cap 6 dismantlement on stack shell 1, more be convenient for medical personnel with the tissue bag liquid of extraction discharge and disinfect in from stack shell 1.

The end of the adjusting screw 5 far away from the tip puncture part 2 penetrates through the cover surface of the adjusting cover 6 and is in threaded connection with the cover surface of the adjusting cover 6. When the adjusting sealing cover 6 is rotated, the adjusting sealing cover 6 can drive the adjusting screw 5 to act, the adjusting screw 5 can move in the cylinder body 1, and then the piston head 3 is driven to move in the cylinder body 1.

When the needle head of the tip puncture part 2 is inserted into the affected part of thyroid gland, the medical staff rotates the adjusting cover 6 to drive the adjusting screw 5 to move in the barrel body 1, and then drive the piston head 3 to move in the barrel body 1, and when the piston head 3 moves in the direction away from the tip puncture part 2, the barrel body 1 part between the piston head 3 and the tip puncture part 2 can be in a negative pressure state, and then tissue cyst fluid or pathological change tissue of the affected part of thyroid gland can be extracted.

Because the tissue capsule liquid is extracted by rotating the adjusting cover 6, the adjusting cover 6 can drive the adjusting screw 5 to move when rotating, and the moving distance of the adjusting screw 5 is fixed by rotating the adjusting cover 6 for one circle because the thread distance between the threads on the adjusting screw 5 is equal, the medical staff can control the amount of the extracted tissue capsule liquid by controlling the circle number of the rotating adjusting cover 6, compared with the traditional method of directly extracting by pulling the piston in the injector, the extraction is convenient, the extraction amount is easier to handle and control, and the possibility of causing pain to patients is reduced.

Example 2:

this example is a further improvement over example 1.

In this embodiment, referring to fig. 1, the adjusting screw 5 is provided with a plane portion parallel to the length direction of the adjusting screw 5, and scale marks are provided on the plane portion. Due to the limitation of the limiting component 4, the movement of the adjusting screw 5 in the cylinder body 1 is smooth, and the condition of rotation in the moving process can not occur. The flat part arranged on the adjusting screw 5 can not influence the driving of the adjusting cover 6 on the adjusting screw 5, the scale is arranged on the adjusting screw 5, and medical staff can more intuitively judge the extraction amount of tissue cyst fluid through the scale extending out of the adjusting screw 5, so that the medical staff can more conveniently control the extraction amount.

Example 3:

this example is a further improvement on the basis of example 1 or example 2.

In this embodiment, referring to fig. 1, anti-skidding lines are formed on the side wall of the adjustment cover 6, and the anti-skidding lines are uniformly distributed along the side wall of the adjustment cover 6. The anti-skid patterns are more convenient for medical staff to rotate and adjust the sealing cover 6, so that tissue cyst fluid of a diseased part is more stable when being extracted.

Example 4:

this embodiment is a further improvement over any of embodiments 1-3.

In this embodiment, referring to fig. 1, the end of adjusting screw 5 stretching out of barrel 1 is fixed with protection piece 7, and protection piece 7 is circular piece, can avoid adjusting screw 5 stretching out the end of barrel 1 and touch medical personnel directly, avoids medical personnel to hurt because of touching adjusting screw 5's end.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
