In addition, due to the design of the connecting hole in the tail end of the needle core, the device can be connected with an electrotherapy instrument, an electrical stimulation function is provided for an operation, the application range of the device is widened, the requirements of more special operations are met, and the treatment effect is further improved.

Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a protective directional cutting small needle knife set. Background Art

[0002] The small needle knife is a medical tool that combines the characteristics of traditional acupuncture needles and modern surgical scalpels. Its shape is both like a needle and a knife. It is developed on the basis of the ancient nine needles and combines the modern medical surgical scalpel. It is a closed release technique between surgical methods and non-surgical therapies. The treatment principle of the small needle knife is mainly to perform operations such as cutting and peeling on the diseased part through its blade to loosen soft tissue adhesions and improve local blood circulation, so as to achieve the effects of relieving pain and promoting disease recovery.

[0003] Although the small needle knife has unique advantages in treating various diseases, there are also certain limitations in the actual operation process. At present, the needle design of the small needle knife cannot intuitively display the penetration depth and the direction of angle rotation, which makes it difficult for doctors to accurately grasp the specific position and state of the needle knife during the treatment operation. Especially in some complex diseased parts, such as around joints and deep in muscles, the control of the depth and angle of the needle knife is particularly important. Due to the lack of intuitive display, doctors can only rely on their own experience and feel to judge, which undoubtedly increases the operation difficulty and risk. At the same time, in clinical training, due to the lack of an intuitive teaching tool, it is more difficult for beginners to master the correct operation techniques of the small needle knife. They often need to practice and grope for a long time to gradually become familiar with the use method of the needle knife. In addition, due to the relatively thin needle of the small needle knife, improper operation is likely to damage the surrounding blood vessels and nerves. During the insertion of the needle knife, if the depth and angle are not properly controlled, it may accidentally injure the adjacent blood vessels, resulting in complications such as bleeding.

[0004] Therefore, there is a need for a protective directional cutting small needle knife set now. This device can fix the depth during the puncture of the small needle knife and can limit the rotatable angle range through setting; while meeting the above effects, the device is convenient and fast to operate; and in order to further enhance the treatment effect of the small needle knife, the device also adds an electric stimulation function. Summary of the Invention

Detailed implementation manner

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Embodiment 1

[0029] The present invention discloses a protective directional cutting small needle knife set, referring to Figures 1 to 4 , which is composed of three parts: a small needle knife assembly 1, a depth component 2, and an angle component 3. The small needle knife assembly 1 is composed of a needle core 101, a base plate 102, and a cover plate 103. The needle core 101 is the sharp part for puncture, and it is fixed inside the base plate 102 to ensure its stability and reliability during operation. The base plate 102 provides support for the needle core 101, while the cover plate 103 is fixed at the upper end of the base plate 102, playing a role in protecting and fixing the needle core 101. At the end of the needle core 101, a connection hole 104 is specially designed, and this connection hole 104 can be used to connect an electrotherapy instrument to provide an electrostimulation function for the operation, increasing the diversity and effectiveness of the treatment. A grip 105 is also fixedly arranged on the top of the cover plate 103, which is convenient for the operator to hold and operate the small needle knife assembly 1.

[0030] The depth component 2 is slidably connected to the small needle knife assembly 1 and is mainly composed of a rubber pad 201 and a scale rod 202. The rubber pad 201 plays a role in buffering and limiting, and protrusions are fixedly arranged at both ends and connected to the scale rod 202. The scale rod 202 is fixedly arranged at both ends of the rubber pad 201, and scales are fixedly arranged on its outer part. By observing these scales, the operator can precisely adjust the distance between the rubber pad 201 and the small needle knife assembly 1, thereby controlling the depth of the needle core 101 entering the patient's skin and ensuring the accuracy and safety of the cutting.

[0031] The angle component 3 is rotatably arranged outside the depth component 2 and is composed of a fixing patch 301, a lower chuck 302 and an upper chuck 303. A medical pressure-sensitive adhesive is fixedly arranged at the bottom of the fixing patch 301, and it can be pasted on the skin of the patient to provide a stable fixing basis for the angle component 3. The lower chuck 302 is fixedly arranged at the upper end of the fixing patch 301, and a first limiting post 304 is fixedly arranged inside it. The upper chuck 303 is detachably arranged at the upper end of the lower chuck 302, and a second limiting post 305 is fixedly arranged inside it. External teeth 306 are fixedly arranged outside the lower chuck 302, and internal teeth 307 are fixedly arranged inside the upper chuck 303. The external teeth 306 are engaged with the internal teeth 307, so that when the upper chuck 303 is installed on the lower chuck 302, the two will not rotate relative to each other. By adjusting the upper chuck 303, the angle between the first limiting post 304 and the second limiting post 305 can be changed. Cooperating with the protrusions arranged on both sides of the rubber pad 201, the rotation angle of the small needle knife component 1 can be restricted to ensure the stability and accuracy of the cutting direction.

[0032] The working principle and usage process of this device are as follows:

[0033] When using a protective type directional cutting small needle knife set, first, the bottom of the fixing patch 301 is coated with a medical pressure-sensitive adhesive, and it is pasted on the skin of the patient at the puncture point position to ensure that the fixing patch 301 is firm.

[0034] Remove the upper chuck 303, change the angle between the first limiting post 304 and the second limiting post 305 as needed, and then install the upper chuck 303 back so that the internal teeth 307 are engaged with the external teeth 306 of the lower chuck 302 and are stably connected.

[0035] Before or during puncture, by observing the scale of the scale rod 202, slide and adjust the distance between the depth component 2 and the small needle knife component 1 to control the depth of the needle core 101 entering the patient's skin and ensure the accuracy of the cutting depth.

[0036] During the operation, due to the existence of the first limiting post 304 and the second limiting post 305, cooperating with the protrusions at both ends of the rubber pad 201, the rotation angle of the small needle knife component 1 can be restricted to ensure the stability of the cutting direction.

[0037] If the operation requires an electrostimulation function, an electrotherapy instrument can be connected to the connection hole 104 at the end of the needle core 101 to realize electrostimulation treatment.

[0038] The above disclosed preferred embodiments of the present invention are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments described.
