Description

Technical Field

[0001] This invention relates to the field of needle knife technology, and in particular to a multi-directional positioning and guiding needle knife device. Background Technology

[0002] Needle-knife therapy, a representative minimally invasive technique combining traditional Chinese and Western medicine, achieves significant therapeutic effects in treating diseases such as neck, shoulder, back, and leg pain through the meridian stimulation of "needles" and the soft tissue release effect of "knife." However, its operation faces the following technical bottlenecks:

[0003] 1. Operational precision depends on experience.

[0004] While existing needle knives (such as the arc-blade needle knife, patent CN201210447675.1) reduce tissue damage through their arc-blade design, the control of the puncture angle still relies entirely on the doctor's feel. Incorrect puncture angles by novice physicians can easily lead to complications such as nerve and blood vessel damage.

[0005] 2. Deficiencies in existing guidance technology

[0006] Electronic navigation systems: Commonly used in conjunction with CT / MRI in clinical practice, this increases the cost per treatment and prolongs the treatment time. (See "Clinical Research Progress and Advantages / Disadvantages Analysis of Visualized Needle Knife Therapy")

[0007] 3. Low efficiency in technology transfer

[0008] In the traditional apprenticeship model, physicians need to complete extensive practical training to master basic angle control techniques, resulting in a long training period. Needle knife therapy relies on the physician's experience to judge angle and depth, lacking real-time data feedback, which can easily lead to operational errors, especially for novice physicians with a steep learning curve. Summary of the Invention

[0009] The purpose of this invention is to provide a multi-directional positioning and guiding needle knife device, which innovatively combines a miniature level (accuracy ±0.5°) with a detachable mechanical structure, so as to achieve real-time digital display of the puncture angle while ensuring the traditional operation habits of needle knife.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a multi-directional positioning and guiding needle knife device, comprising a needle knife body and a detachable U-shaped mounting plate, wherein the needle knife body is integrally formed from a needle body and a handle, and the upper end of the handle is detachably mounted with a U-shaped mounting plate, wherein a high-precision miniature level and a real-time display screen are integrated on the U-shaped mounting plate, wherein a mounting groove is recessed in the top of the U-shaped mounting plate, and the miniature level body is embedded in the inner wall of the mounting groove, and the U-shaped mounting plate is also provided with a real-time display screen for displaying the angle data of the miniature level body.

[0011] Preferably, the handle surface has a recessed slot, and the inner wall of the U-shaped mounting plate has a rod fixedly inserted into it, which is slidably inserted into the inner wall of the slot.

[0012] Preferably, the inner wall of the slot is recessed and has a slot, and a rubber clip is elastically engaged with the inner wall of the slot, and the rubber clip is fixedly installed on the surface of the insertion rod.

[0013] Preferably, the card slots are arranged vertically on the inner wall of the slot.

[0014] Preferably, the insertion rod is arranged symmetrically on the inner wall of the U-shaped mounting plate with the mounting groove as the center.

[0015] Preferably, the handle surface is provided with anti-slip texture, and the end face of the insertion rod is on the same horizontal line as the handle surface.

[0016] Compared with related technologies, the multi-directional positioning and guiding needle knife device provided by the present invention has the following beneficial effects:

[0017] This invention provides a multi-directional positioning and guiding needle knife device. By fitting a U-shaped mounting plate onto the upper end of the handle, the angle of the needle knife body is measured by a miniature level. Medical personnel can then insert the needle into the patient's body for treatment by holding the handle. During the process, the miniature level can display the current angle of the needle knife body on a real-time display screen, allowing medical personnel to more directly observe the insertion angle of the needle knife body.

[0018] This invention provides a multi-directional positioning and guiding needle knife device, which can install and remove the U-shaped mounting plate and the needle knife body by inserting a rod into the inner wall of the slot. This allows the U-shaped mounting plate to be removed and reused without affecting the normal operation of the needle knife body by medical staff. Attached Figure Description

[0024] Please see Figures 1-4 The present invention provides a technical solution including a needle knife body 1 and a detachable U-shaped mounting plate 2. The needle knife body 1 is integrally formed from a needle body 11 and a handle 12. The upper end of the handle 12 is detachably mounted with the U-shaped mounting plate 2. The U-shaped mounting plate 2 integrates a high-precision miniature level 22 and a real-time display screen 23. The top of the U-shaped mounting plate 2 is recessed with a mounting groove 21. The miniature level body 22 is embedded in the inner wall of the mounting groove 21. The U-shaped mounting plate 2 is also provided with a real-time display screen 23 for displaying the angle data of the miniature level body 22.

[0025] By fitting the U-shaped mounting plate 2 onto the upper end of the handle 12, the angle of the needle knife body 1 is measured by the miniature level body 22. Then, medical staff can insert the needle body 11 into the patient's body for treatment by holding the handle 12. During the process, the miniature level body 22 can display the current angle of the needle knife body 1 on the real-time display screen 23, so that medical staff can more directly observe the insertion angle of the needle knife body 1.

[0026] The handle 12 has a recessed slot 13, and the U-shaped mounting plate 2 has a rod 24 fixedly installed on its inner wall. The rod 24 is slidably inserted into the inner wall of the slot 13.

[0027] The U-shaped mounting plate 2 and the needle knife body 1 can be installed and removed by inserting the rod 24 into the inner wall of the slot 13, so that the U-shaped mounting plate 2 can be removed and reused without affecting the normal operation of the needle knife body 1 by medical staff.

[0028] The inner wall of the slot 13 is recessed and has a slot 14. The inner wall of the slot 14 is elastically engaged with a plastic clip 25, which is fixedly installed on the surface of the insertion rod 24. The slots 14 are vertically arranged on the inner wall of the slot 13. The insertion rod 24 is symmetrically arranged on the inner wall of the U-shaped mounting plate 2 with the mounting slot 21 as the center.

[0029] The elastic engagement between the rubber clip 25 and the inner wall of the slot 14 allows the insertion rod 24 to be stably inserted into the inner wall of the slot 13, ensuring that the miniature level body 22 remains fixed during the use of the needle knife body 1.

[0030] The surface of the handle 12 is provided with anti-slip texture, and the end face of the insertion rod 24 is on the same horizontal line as the surface of the handle 12;

[0031] Increase the friction when medical staff hold the handle 12 to prevent it from slipping out of their hands and make it easier to use.
