Detailed ways

Please refer to Figures 1 to 4. In the embodiment of the present utility model, a new type of interventional treatment needle for tumors includes a cylinder body 13. The upper surface of the cylinder body 13 is fixedly equipped with the first holding assembly 6, and the cylinder body 13 The lower surface of the second grip assembly 12 is fixedly installed, the first grip assembly 6 includes a bracket 5, a finger groove 7 and a connecting frame 8, and the internal components of the first grip assembly 6 and the second grip assembly 12 are the same, The top of the connecting frame 8 is fixedly installed with a bracket 5, and the bottom end of the connecting frame 8 is fixedly connected with the cylinder body 13 by bolts. The inside of the connecting frame 8 is provided with four finger grooves 7, and the inner walls of the finger grooves 7 are uniformly bonded with rubber The anti-slip sleeve, and the finger groove 7 is a semicircular structure. Through the combined use of the first grip component 6 and the second grip component 12, the stability of the user in the process of taking the cylinder 13 can be increased, which is convenient for the user Align the needle body 1 with the treatment position of the patient.

One side of the cylinder 13 is fixedly installed with a limit assembly 14, the limit assembly 14 includes a first limit hole 3, a collar 4 and a fixed disk 15, the outer thread of the fixed disk 15 is sleeved with the collar 4, and the fixed disk 15 There is a first limiting hole 3 in the inside, the collar 4 and the cylinder 13 are fixedly connected by bolts, the first limiting hole 3 and the second limiting hole 18 are on the same horizontal line, and the first limiting hole 3 and the second limiting hole The diameters of the two limiting holes 18 are equal, and the first limiting hole 3 and the second limiting hole 18 are all slidably connected with the needle body 1. Through the combined use of the limiting assembly 14 and the limiting disc 17, the needle body 1 can be adjusted simultaneously. The position-limiting function prevents the needle body 1 from deviating and causing the puncture accuracy to decrease.

The other side of the cylinder 13 is embedded with an adjustment assembly 9, and the interior of the cylinder 13 is fixedly installed with a limit plate 17. The inside of the limit plate 17 is provided with a second limit hole 18, and one end of the adjustment assembly 9 is connected with a needle body. 1. The front surface of the needle body 1 is provided with a scale line 2. The adjustment assembly 9 includes a turntable 10, a threaded rod 11 and a piston 16. One end of the threaded rod 11 is welded with a turntable 10, and the other end of the threaded rod 11 is movably connected to a piston 16. , the threaded rod 11 is threadedly connected to the cylinder body 13, and the piston 16 is slidingly connected to the cylinder body 13. The user can easily extend and store the needle body 1 by adjusting the assembly 9. When the needle body 1 is stretched, it is convenient to adjust the Puncture the corresponding part, and when the needle body 1 is stored, its footprint can be reduced, accidental injury can be prevented, and the practical performance of the interventional therapy needle can be improved.

The working principle of the utility model is: the inside of the threaded rod 11, the piston 16 and the needle body 1 are respectively provided with a first round hole, a second round hole and a third round hole, and the first round hole, the second round hole and the first round hole The three round holes are equal in size, and the first round hole, the second round hole and the third round hole are on the same horizontal line. The user first puts his finger into the finger groove 7, and now the finger groove 7 can give the user a finger. The focus point is convenient for the user to take it. Through the combined use of the first holding component 6 and the second holding component 12, the stability of the user in the process of taking the cylinder 13 can be increased, and it is convenient for the user to hold the barrel 13. The needle body 1 is aimed at the treatment position of the patient, and then the user inserts the needle body 1 into the corresponding treatment position. At this time, the user rotates the turntable 10 clockwise, which drives the threaded rod 11 to rotate clockwise, and then drives the piston 16 to Move to the left, at this time the needle body 1 is gradually extended, when the user turns the turntable 10 counterclockwise, the piston 16 is driven to move to the right, at this time the needle body 1 is gradually shortened, and the elongation of the needle body 1 can pass through the scale line 2 Precise control is carried out, so the user can easily stretch and store the needle body 1 by adjusting the component 9. When the needle body 1 is stretched, it is convenient to puncture the corresponding part at this time. When the needle body 1 is stored, it can reduce its occupation. The ground area prevents accidental injury and improves the practical performance of the interventional therapy needle. Since the needle body 1 is located in the first limiting hole 3 and the second limiting hole 18, the first limiting hole 3 and the second limiting hole 18 can play the role of double-layer limit on the needle body 1. Through the combined use of the limit component 14 and the limit plate 17, it can limit the needle body 1 and prevent the needle body 1 from shifting and causing puncture. For the problem of decreased accuracy, the user only needs to insert the guide wire along the first round hole, the second round hole and the third round hole, and the interventional treatment can be performed at this time.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent replacement or change of the technical solution of the utility model and the concept of the utility model shall be covered by the protection scope of the utility model.
