Technical Field
[0001] The utility model relates to an anti-skid scale needle knife. Background Art
[0002] The emergence of the needle knife tool was triggered by an accidental event. The formation of needle knife therapy was gradually formed on the basis of a large number of clinical practices and experimental studies. On July 15, 2006, the National TCM Minimally Invasive Academic Conference established the concept of "needle knife" "TCM minimally invasive medicine", reinterpreting medicine with "minimally invasive", repositioning medicine, and reshaping medicine, so that medicine can return to its origin. Small needle knife therapy is a closed release technique between surgical methods and non-surgical therapies. It is formed on the basis of combining open surgery and acupuncture. The characteristic of small needle knife treatment surgery is that it is easy to cut and peel the deep part of the treatment site to the lesion, so as to achieve the purpose of relieving pain and eliminating the disease. Its indications are mainly soft tissue injury lesions and bone and joint degenerative lesions. As an original TCM minimally invasive treatment method, small needle knife therapy has the advantages of simple operation, small incision, mild pain or no pain throughout the process compared with open surgery. If the indications and operating procedures are strictly controlled, it has the advantages of safety, effectiveness and few complications.
[0003] Acupuncture knife treatment requires the use of the blade of the acupuncture knife to break the skin and penetrate into the deep layer of the muscle, reaching the bone surface, tendon or nerve sheath according to the situation. Therefore, there are strict requirements on the depth of needle insertion for doctors, especially beginners. In the prior art, when doctors perform acupuncture knife therapy, they rely entirely on experience and feeling to determine the depth of insertion, which makes it impossible to accurately determine the depth of the blade entering the human body. The acupuncture knife is relatively small in size, and the anti-slip effect is not good enough during use.

[0051] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.
[0052] Figures 1 to 7The figure shows a schematic diagram of the structure of an embodiment of the anti-slip graduated needle knife of the utility model. The anti-slip graduated needle knife comprises a needle knife body 1 and a gripping end 2, wherein the gripping end 2 is mounted on the end of the needle knife body 1 away from the needle tip.
[0053] A contact ring 3, which is arranged outside the acupuncture knife body 1 and is used to assist in indicating the depth of the acupuncture knife body 1 inserted into the skin;
[0054] A toothed scale indicator rod 4, one end of which is connected to the contact ring 3, and the other end of which is slidably connected to the gripping end 2, and the toothed scale indicator rod 4 is used to determine the depth of the needle knife body 1 extending into the skin;
[0055] The anti-skid component 5 is arranged on the outside of the gripping end 2 to prevent sliding during use.
[0056] In the present technical solution, the contact ring 3 and the toothed scale indicator rod 4 can be used to confirm the depth of the needle knife body 1 inserted into the skin, so that the doctor can accurately determine the depth of the blade entering the human body, thereby facilitating the needle knife treatment. At the same time, the anti-slip component 5 can absorb the sweat on the user's hands, making the needle knife have better anti-slip properties, preventing the needle knife from slipping during use, making the user more stable when holding the needle knife, and facilitating the operation of the needle knife.
[0057] A plurality of sliding balls 6 are rotatably connected to the inner side of the contact ring 3 , and a side of the sliding balls 6 away from the contact ring 3 is in contact with the surface of the needle knife body 1 .
[0058] In the present technical solution, the sliding ball 6 is used to enable the contact ring 3 to slide stably along the needle knife body 1 .
[0059] When in use, the user holds the holding end 2 and inserts the needle knife body 1 into the patient's skin. At this time, the patient's skin automatically moves the contact ring 3 upward, and at the same time drives the toothed scale indicator rod 4 to move upward. At this time, the depth of the needle knife body 1 inserted into the skin is judged according to the distance that the upper end of the holding end 2 moves out of the holding end 2.
[0060] The top of the contact ring 3 is connected to two symmetrically distributed toothed scale indicator rods 4, and teeth are arranged on opposite sides of the two toothed scale indicator rods 4;
[0061] The top ends of the two toothed scale indicator rods 4 are both connected to the lower side of the connecting plate 8 .
[0062] In the present technical solution, the two toothed scale indicating rods 4 can be connected by using the connecting plate 8 .
[0063] The upper and lower sides of the holding end 2 are provided with sliding holes, and the upper end of the toothed scale indicating rod 4 is slidably connected with the holding end 2 through the sliding holes.

[0065] The limiting assembly 7 includes a bidirectional threaded column 71, the bidirectional threaded column 71 is rotatably connected to the side of the gripping end 2, and a movable limiting plate 72 is threadedly connected to the surface of the bidirectional threaded column 71;
[0066] The movable limiting plate 72 is provided with teeth on both sides, and the movable limiting plate 72 can be engaged with the toothed scale indicating rod 4.
[0067] In the present technical solution, the position of the toothed scale indicator rod 4 can be limited by the limit assembly 7, the distance between the needle tip of the needle knife body 1 and the contact ring 3 can be controlled, and the penetration degree of the needle knife body 1 can be controlled.
[0068] When it is necessary to control the depth of the needle knife body 1 penetrating into the skin, move the contact ring 3 and the toothed scale indicator rod 4 upwards to determine the distance between the tip of the needle knife body 1 and the bottom of the contact ring 3, and then rotate the rotating disk 74 to drive the bidirectional threaded column 71 to rotate. At this time, the movable limit plates 72 on both sides are driven to move toward each other along the positioning strips 73, so that the movable limit plates 72 are attached to and engaged with the toothed scale indicator rod 4. At this time, the contact ring 3 cannot move, and the user can directly control the depth of each insertion.
[0069] It is worth noting that when the needle knife is not in use, the contact ring 3 moves to the bottom and is fixed. At this time, the bottom of the contact ring 3 is lower than the needle tip of the needle knife body 1, thereby preventing the needle tip of the needle knife body 1 from injuring other people and ensuring safety.
[0070] A plurality of positioning bars 73 are connected to the inner cavity of the needle knife body 1 , and the surfaces of the positioning bars 73 are slidably connected to the movable limiting plates 72 .

[0072] A preset hole is opened on the side of the needle knife body 1, and both ends of the bidirectional threaded column 71 are rotatably connected to the holding end 2 through the preset hole.
[0073] In this technical solution, the two-way threaded column 71 can drive the movable limiting plate 72 to move when it rotates.
[0074] Both ends of the bidirectional threaded column 71 away from the holding end 2 are connected to a rotating disk 74 .
[0075] In the present technical solution, the rotating disk 74 can be used to facilitate the rotation of the bidirectional threaded column 71 .
[0076] The anti-skid component 5 includes an anti-skid rubber strip 51, and a plurality of anti-skid rubber strips 51 are connected to both sides of the gripping end 2;
[0077] A water-absorbing cotton strip 52 is arranged between two adjacent anti-slip rubber strips 51 , and the water-absorbing cotton strip 52 is detachably connected to the side surface of the gripping end 2 via a disassembly assembly 53 .
[0078] In the present technical solution, the anti-skid component 5 can be used to prevent the needle knife from slipping when in use.
[0079] The disassembly assembly component 53 includes a Velcro mother patch 531 and a Velcro sub-patch 532, the Velcro mother patch 531 is connected to the side of the holding end 2, the Velcro sub-patch 532 is connected to one side of the absorbent cotton strip 52, and the Velcro mother patch 531 and the Velcro sub-patch 532 are detachably bonded.
[0080] In the present technical solution, the absorbent cotton strip 52 can be replaced by using the disassembly assembly 53 .
[0081] When the needle knife is in use, the user holds the gripping end 2, and the anti-skid rubber strip 51 can prevent the needle knife from slipping. At the same time, the absorbent cotton strip 52 can absorb the sweat on the user's hand, further preventing the needle knife from slipping due to sweat, thereby improving the anti-skid performance of the needle knife.
[0082] The water-absorbing cotton strip 52 can be replaced by using the Velcro mother patch 531 and the Velcro child patch 532 to prevent the water-absorbing cotton strip 52 from absorbing too much liquid and losing its liquid absorption function.
