Description

A ring-type needle knife

technical field

The utility model relates to the technical field of surgical medical instruments, in particular to a ring-type small needle knife.

Background technique

The small needle knife is a kind of medical surgical tool made of metal materials, which looks like a needle and a knife in shape. It is developed on the basis of acupuncture tools such as traditional Chinese medicine needles and other acupuncture tools, combined with a modern medical surgical scalpel. , has a history of more than ten years. The operation of small needle-knife therapy is characterized by piercing deep into the treatment site to easily cut and peel off the lesion, so as to achieve the purpose of relieving pain and eliminating disease. Its indications are mainly soft tissue injury lesions and bone and joint lesions.

Small needle knives are slightly different in shape and length, and generally consist of three parts: the handle, the needle body, and the needle knife. The handle of the currently used small acupotomy is coaxial with the acupotomy, and it needs to be clamped and operated by the thumb and other fingers. It is extremely inconvenient to use, the accuracy of the operation is not easy to control, and the doctor's fingers are prone to fatigue. When performing needle-knife segmentation and peeling, since the needle-knife enters the human tissue, it is not operated under direct vision, and it is easy to have excessive range and other improper techniques, resulting in damage to important tissues such as blood vessels and nerves.

Utility model content

The purpose of this utility model is to provide a ring-type small needle knife, which is used for closed surgical release of chronic soft tissue injuries and bone and joint lesions. It has a simple structure, is easy to operate, and is safe and convenient to use.

In order to achieve the above object, the technical solution of the utility model is:

A small ring-type needle knife, comprising a ring-type needle handle, a needle body and a blade; the ring-type needle handle is fixedly connected to the rear end of the needle body, and the blade is fixedly connected to the needle body The front end of the ring-type needle handle, the needle body and the blade are connected into an integral structure; the ring-type needle handle includes a circular structure, an oblique section and a raised point structure, and one of the circular structure The middle part of the side is connected with the needle body, and the oblique section is set on the upper middle part of the other side of the circular structure. The bump structure is evenly distributed on the oblique section.

In the ring-type small needle knife mentioned above, the raised point structure is integrated with the oblique cross-section.

The utility model has the advantages of simple structure and reliable operation, and can more effectively control the needle insertion depth of the needle body and the sensitivity during stripping operation, and reduce the risk of damage to blood vessels and nerves.

Description of drawings

Fig. 1 is a structural schematic diagram of a ring type small needle knife of the present invention.

detailed description

Further illustrate the embodiment of the present utility model below in conjunction with accompanying drawing.

Please refer to the accompanying drawing 1, a ring-type small needle knife, comprising a ring-type needle handle 1, a needle body 2 and a blade 3; the ring-type needle handle 1 is fixedly connected to the rear end of the needle body 2 , the blade 3 is fixedly connected to the front end of the needle body 2, and the ring-type needle handle 1, the needle body 2 and the blade 3 are connected into an integral structure; the ring-type needle handle 1 includes a circular Structure 101, oblique section 102 and bump structure 103, the middle part of one side of the circular structure 101 is connected with the needle body 2, and the oblique section 102 is set on the circular structure On the other side of 101 In the upper part, the oblique section 102 is an inclined slope structure facing upward and backward, and the bump structures 103 are evenly distributed on the oblique section 102 .

The bump structure 103 is integrated with the oblique section 102 .

When in use, the doctor inserts the index finger into the ring-shaped needle handle 1, and presses the thumb on the convex point structure 103 of the oblique section 102 to control the needle body 2 and the blade 3. The oblique section 102 can increase friction and improve grip The role of stability.

In describing the present invention, it should be understood that the terms "rear end", "front end", "one side", "middle part", "other side", "middle upper part", "rear upper part" etc. indicate The orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation or be constructed in a specific orientation. and operation, and therefore cannot be construed as a limitation of the present utility model.

In this utility model, unless otherwise clearly specified and limited, terms such as "setting", "inserting", "connecting", "fixing", and "distributing" should be understood in a broad sense, for example, it can be a fixed connection, or It can be detachably connected or integrated; it can be directly connected or indirectly connected through an intermediary, and it can be internal communication between two elements or an interaction relationship between two elements, unless otherwise clearly defined. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present utility model according to specific situations.

To sum up, the utility model has a simple structure and reliable operation, can more effectively control the needle insertion depth of the needle knife and the sensitivity of the stripping operation, and reduce the risk of damage to blood vessels and nerves.

The above is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made by the contents of the specification of the utility model, or direct or indirect use of the technical fields attached to other related products , are all included in the scope of patent protection of the utility model in the same way.
