Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: a flexibly fixable breast puncture positioning needle, comprising an outer sleeve 1, an adjusting block 2 is provided on one side of the outer sleeve 1, a rotating cylinder 6 is fixedly connected to the center of one side of the adjusting block 2, one side of the rotating cylinder 6 passes through the interior of the outer sleeve 1, a ball 8 is rollingly installed on the outer wall of the rotating cylinder 6, a rolling groove 7 is opened on one side of the inner wall of the outer sleeve 1, a threaded groove 5 is opened in the center of one side of the adjusting block 2, a positioning needle body 3 is provided on one side of the adjusting block 2, and a threaded sleeve 4 is fixedly installed on the center position of the surface of the positioning needle body 3.

[0022] The rolling groove 7 is an annular structure, and the number of balls 8 is several. The surfaces of the several balls 8 penetrate into the interior of the rolling groove 7 and contact the inner wall of the rolling groove 7, so that the adjustment block 2 can rotate smoothly and is easy to adjust.

[0023] One end of the positioning needle body 3 passes through the threaded groove 5, the rotating cylinder 6 and the interior of the outer sleeve 1 in sequence. The outer wall of the threaded sleeve 4 is threadedly connected to the inner wall of the threaded groove 5. When the adjusting block 2 rotates, the positioning needle body 3 can be driven to move through the thread transmission.

[0024] A slide groove 10 is provided in the center of the top and bottom of the outer sleeve 1. A fixing ring 9 is fixedly installed on the surface of the positioning needle body 3 corresponding to one end of the threaded sleeve 4. The centers of the top and bottom of the fixing ring 9 are fixedly connected with connecting rods 11. The top and bottom of the two connecting rods 11 are fixedly connected with sliders 12. The two sliders 12 are respectively slidably connected to the two slide grooves 10, ensuring that the positioning needle body 3 will not rotate with the adjusting block 2.

[0025] One end of the outer tube 1 is fixedly connected to four fixing posts 13, one side of the four fixing posts 13 is fixedly connected to an adhesive disc 14, one side of the adhesive disc 14 is fixedly adhered to a medical adhesive layer 15, and the adhesive disc 14 is arranged in an annular structure, so that the outer tube 1 can be firmly adhered to the patient's skin. Even if the patient moves slightly during the operation, it can effectively prevent the outer tube 1 from falling off or displacing, thereby improving the stability and safety of the operation.

[0026] The adjustment block 2 is arranged in a ring structure, and the surface of the adjustment block 2 is provided with anti-slip vertical grooves, so that medical staff can have a better grip and control when rotating the adjustment block 2, preventing operational errors caused by hand slippage, and improving the accuracy and reliability of surgical operations.

[0027] A transparent observation plate is fixedly installed on one side of the surface of the outer sleeve 1, so that medical staff can clearly observe the puncture position and depth of the positioning needle body 3 without removing the outer sleeve 1, facilitating timely adjustment and confirmation, thereby improving the efficiency and accuracy of the operation.

[0028] A hard guide wire 16 is provided inside the outer sleeve 1, and one end of the hard guide wire 16 is fixedly connected to a barb 17. The barb 17 can firmly hook the lesion. Even if a certain force is generated during the patient's breathing, movement or operation, the hard guide wire 16 will not fall off from the lesion.

[0029] Working principle: First, the outer sleeve 1 is firmly attached to the patient's skin through the adhesive disc 14 at one end of the outer sleeve 1 and the medical adhesive layer 15 attached thereto to ensure its stability during the operation. Then, the medical staff rotates the adjustment block 2, and the rotation of the adjustment block 2 drives the rotating drum 6 fixed to it to rotate together, and the ball 8 on the outer wall of the rotating drum 6 rolls in the rolling groove 7 on the inner wall of the outer sleeve 1, effectively reducing the friction during rotation and making the adjustment process smoother. As the adjustment block 2 rotates, the threaded groove 5 inside it and the threaded sleeve 4 on the surface of the positioning needle body 3 are threadedly driven, thereby driving the positioning needle body 3 to move linearly inside the outer sleeve 1. This process In the process, the fixing ring 9 on the positioning needle body 3 is connected to the slider 12 through the connecting rod 11, and the slider 12 slides in the slide groove 10 at the top and bottom of the outer tube 1, ensuring that the positioning needle body 3 maintains linear motion during movement and will not rotate with the rotation of the adjustment block 2, further improving the accuracy and stability of puncture; during the puncture process, under the guidance of X-rays, the positioning needle body 3 first punctures into a deeper position in the lesion, and the barb 17 at the front end of the hard guide wire 16 is in a linear contracted state in the positioning needle body 3. Medical staff can observe the puncture position and depth of the positioning needle body 3 in real time through the transparent observation plate on the surface of the outer tube 1, so as to make timely adjustments and confirmations to ensure The accuracy of puncture: once the puncture is completed and reaches the predetermined depth, the rotation of the adjustment block 2 can be stopped. At this time, the positioning needle body 3 is firmly fixed in the patient's body. During the whole process, due to the firm adhesion of the outer sleeve 1 and the stable movement of the positioning needle body 3, the positioning needle is effectively avoided from falling off or displacing due to patient activities or improper operation, thereby improving the safety and success rate of the operation. After the puncture positioning needle reaches the predetermined depth and confirms the accuracy of the position, the medical staff gradually withdraws the positioning needle body 3, and the barb 17 in the linear contraction state is exposed on the positioning needle body 3 and is in a scattered state, so that the tip of the barb 17 can hook the lesion site, and the hard guide wire 16 and the barb are used to connect the lesion. 17 is used to fix the position of the lesion to ensure the stability and accuracy of subsequent operations; since the hard guide wire 16 has a certain flexibility, it can conform to the slight bend of the puncture path to ensure that it reaches the target position smoothly. The medical staff will continue to pull the hard guide wire 16 slowly and steadily so that the barb 17 can hook a part of the lesion. Due to the special design of the barb 17, it can firmly grasp the lesion. Even if a certain force is generated during the patient's breathing, movement or operation, the hard guide wire 16 will not fall off the lesion. After confirming that the barb 17 has firmly hooked the lesion, the medical staff checks its fixation. At this time, the positioning needle body 3 and the hard guide wire 16 together form a stable fixation system;After the puncture is complete, the medical staff rotates the adjustment block 2 again to remove the positioning needle body 3 from the patient's body. The outer cannula 1 is then removed from the patient, leaving the hard guide wire 16 inside. The surgeon then disinfects the area and makes an incision along the direction of the hard guide wire 16, ensuring complete removal of the diseased tissue while preserving as much normal breast tissue as possible. This precise excision method helps reduce surgical trauma and promotes postoperative recovery.

[0030] To sum up: the flexibly fixable breast puncture positioning needle, through the design of the outer sleeve 1, adjustment block 2, threaded sleeve 4, threaded groove 5, rotating cylinder 6 and ball 8, sticks the outer sleeve 1 on the patient's skin, and combines the threaded connection mechanism of the adjustment block 2 and the threaded sleeve 4, the medical staff can conveniently control the entry and exit depth of the positioning needle body 3 by rotating the adjustment block 2, thereby realizing the precise adjustment of the puncture depth. This threaded transmission design not only ensures the stability and controllability of the puncture operation, but also significantly improves the flexibility and accuracy of the operation. During the puncture process, the threaded sleeve 4 can firmly drive the positioning needle body 3 for puncture, effectively preventing the positioning needle from being offset due to improper operation or patient activity, thereby ensuring the success rate of the operation and the safety of the patient, and effectively avoiding the problem of the positioning needle falling off or displacing during the operation, significantly improving the flexibility and fixation effect of the operation, and providing a strong guarantee for the precise treatment of breast diseases.
