Abstract

The utility model belongs to the technical field of medical instruments, and particularly relates to a novel threaded needle knife which comprises a handle, a needle body and a needle blade, wherein the upper end of the needle body is fixedly connected with the handle, the lower end of the needle body and the needle blade are integrally formed, the needle body sequentially comprises a smooth needle section and a threaded needle section which are integrally formed from top to bottom, and a spiral groove group is arranged on the surface of the threaded needle section. The thread needle knife designs the smooth needle surface into the thread section within the range of 0.5 cm-2 cm on the needle blade at the lower part of the needle body, and designs the special spiral groove group on the surface of the thread section, so that the adsorption force between the needle body and muscle tissue can be increased, the position of the needle body can be relatively fixed after the needle knife penetrates into the tissue, and the cut part can be accurately mastered.

Description

Novel thread needle knife

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a novel threaded needle knife.

Background

The needle knife therapy integrates the basic theory of traditional Chinese medicine and the basic theory of western medicine operation and dissection, and is a closed loosening operation between an operation method and a non-operation therapy. The needle knife therapy has the advantages of simple operation in the treatment process, small incision, no need of suture, small damage to human tissues, difficult infection, no adverse reaction, no obvious pain and fear of patients, no rest after operation, short treatment time, short treatment course and easy acceptance of patients. The needle knife is developed by combining a modern medical surgical scalpel on the basis of needles, spike needles and the like in ancient nine needles, and is a product organically combined with soft tissue loosening operation. Needle knife treatment requires that the knife edge of the needle knife is utilized to break the skin and penetrate into the deep layer of the muscle in a proper way, and reaches the bone surface or touches the nerve sheath membrane according to the situation, and the subcutaneous tissue situation is complex, so that the position of the needle body is required to be kept relatively fixed during the operation process of an operator. So that strict requirements are placed on the physician, especially a beginner, to maintain needle stability after needle insertion. In the prior art, when a clinician performs needle knife therapy, after a needle body is penetrated into human skin, the position of the needle body may deviate due to a plurality of factors, so that the needle knife is difficult to maintain at a fixed position.

Disclosure of Invention

The utility model aims to overcome the defect that the needle position is easy to deviate so that the needle knife is difficult to maintain the fixed position in the prior art, and provides a novel threaded needle knife, so that an operator can fix the needle position after penetrating the needle knife into tissues in the operation process, and the cutting part is accurately mastered.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel screw thread needle sword, includes handle, needle body and needle cutting edge, the upper end of needle body with handle fixed connection, the lower extreme and the needle cutting edge integrated into one piece of needle body, the needle body includes integrated into one piece's smooth needle section and screw thread needle section from last to down in proper order, the surface of screw thread needle section is equipped with spiral line recess group.

Further, the spiral groove group is composed of three spiral grooves in a triple-spiral structure.

Preferably, the symmetry axes of the three spiral concave veins are respectively separated by 120 degrees.

Preferably, the pitch of the three spiral grooves is 1.5mm.

Preferably, the total length of the needle body is 4 cm-12.5 cm, and the diameter is 0.4 mm-3.0 mm.

Preferably, the length of the threaded needle section is 0.5 cm-2 cm.

The thread needle knife designs the smooth needle surface into the thread section within the range of 0.5 cm-2 cm on the needle blade at the lower part of the needle body, and designs the special spiral groove group on the surface of the thread section, so that the adsorption force between the needle body and muscle tissue can be increased, the position of the needle body can be relatively fixed after the needle knife penetrates into the tissue, and the cut part can be accurately mastered.

Drawings

FIG. 1 is a schematic front view of the general structure of the present utility model;

FIG. 2 is a cross-sectional view at A-A of FIG. 1;

the labels in fig. 1-2 have the following meanings: 1-handle, 2-needle body, 21-smooth needle section, 22-threaded needle section, 221-spiral concave pattern and 3-needle blade.

Detailed Description

It is to be understood that in the description of the present utility model, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is intended merely to facilitate description of the present utility model and to simplify the description, and is not to indicate or imply that the components referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the present utility model.

Specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

The utility model provides a novel screw thread needle sword, is shown as fig. 1, includes handle 1, needle body 2 and needle cutting edge 3, the upper end of needle body 2 with handle 1 fixed connection, the lower extreme of needle body 2 and needle cutting edge 3 integrated into one piece, needle body 2 includes integrated into one piece's smooth needle section 21 and screw thread needle section 22 from last to down in proper order, screw thread needle section 22's surface is equipped with spiral line recess group, spiral line recess group is three spiral structures by three spiral concave lines 221 and constitutes.

As shown in fig. 2, the symmetry axes of the three spiral grooves 221 are respectively spaced 120 ° apart, and the pitch of the three spiral grooves 221 is 1.5mm.

In this embodiment, the total length of the needle body 2 is 10.0cm, and the diameter is 1.0mm; the length of the threaded needle section 22 is 2.0cm.

The thread needle knife designs the smooth needle surface into the thread section within the range of 0.5 cm-2 cm on the needle blade 3 at the lower part of the needle body, and designs the special spiral groove group on the surface of the thread section, so that the adsorption force between the needle body and muscle tissue can be increased, the position of the needle body can be relatively fixed after the needle knife penetrates into the tissue, and the cut part can be conveniently and accurately mastered.

25 doctors randomly select the novel threaded needle knife to apply needle knife therapy, and the results show that by questionnaire investigation on patients and doctors: in the operation process, a doctor can fix the position of the needle body after the threaded needle knife disclosed by the utility model is penetrated into tissues, the cutting position is accurately mastered, and the device has an outstanding operation lifting effect especially for keeping the stability of the needle body after the needle is inserted by a beginner, so that the device fully meets strict requirements.

What is not described in detail in the present specification is all that is known to those skilled in the art. The special-shaped piece used in the utility model can be customized according to the description of the specification and the drawings, and the detailed description is omitted.
