Description

Threading device for thread burial needle

Technical Field

The utility model relates to a medical instrument especially relates to a thread embedding needle threading device.

Background

In recent years, catgut embedding therapy using a catgut embedding needle as a medical operation instrument has been widely applied to treatment of diseases of internal medicine, gynecology, pain department, orthopedics, five sense organs department and the like, and with the development of technology and concept, new catgut embedding technologies such as sphenopalatine ganglion catgut embedding, stellate ganglion catgut embedding, and intervertebral foramen external catgut embedding are developed in clinic.

The thread burial needle in the market is threaded manually, the thread burial needle is more difficult to thread like the needle eye threading in our life, and as the thread burial needle is used more and more in the medical industry, a plurality of doctors need to wear the thread for hundreds of times or more a day, and the eyes are tired after a long time.

The published Chinese utility model patent has the publication number: CN207400917U, patent name: disposable acupuncture needle device of sunkening cord, application date: 20170224, it discloses a disposable acupuncture thread-embedding needle device, which is provided with: the needle handle is provided with a hollow thread-buried needle tube with an oblique cutting edge, a human body absorbable thread and a hollow protective sleeve; the middle of the thread body is bent into two sections with similar or equal length, wherein one end of the thread body extends into an inner hole of a blade of the hollow thread-buried needle tube, the other end of the thread body is positioned at the outer side of the hollow thread-buried needle tube, and the needle tube is locked and tightly attached by a foam sponge thread locking device sleeved on the outer wall of the lower side of the needle tube to form a thread-buried needle tool with integrated needle and thread; the thread burying needle is placed in the inner hole of the hollow protective sleeve, and is tightly attached and embedded with the needle handle through the small plastic inserting piece, so that the thread burying needle is clamped and fixedly arranged in the hollow protective sleeve and is used for protecting the sanitation and cleanness of the thread burying needle when the device is used for packaging, transportation, carrying out or other thread burying operations without using the device. The device keeps the needle and line unification, and the advantage of convenient to carry has solved the multiple defects of current acupuncture point catgut embedding needle's complicated structure, and the operation is inconvenient, requires operation skill height, is susceptible to infection.

SUMMERY OF THE UTILITY MODEL

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a cross-sectional view of the present invention;

in the figure, the position of the upper end of the main shaft,

1. an upper end head; 2. a lower end head; 3. a middle channel; 4. a thread burial needle.

Detailed Description

The present invention will now be described in detail with reference to the drawings, which are provided for illustrative and explanatory purposes only and should not be construed as limiting the scope of the present invention in any way.

In the threading device shown in fig. 1, an operator uses forceps to hold a medical suture (catgut) and feeds the medical suture into the threading device from an upper end 1; the thread burial needle is upwards inserted into the middle channel 3 from the lower end head 2 and fixed; the suture line enters the needle body of the thread burial needle inserted into the middle channel 3 through the guiding of the upper end head 1, and the threading is completed.

In this embodiment, it is preferable that the inner diameter of the smallest opening of the upper tip 1 is smaller than the inner diameter of the smallest opening of the lower tip 2.

In this embodiment, it is preferable that the maximum opening inner diameter of the upper tip 1 is larger than the maximum opening inner diameter of the lower tip 2.

In this embodiment, it is preferable that the inner diameter of the middle channel 3 gradually increases from the minimum opening of the upper end head 1 to the minimum opening of the lower end head 2.

In the embodiment, preferably, the inner diameter of the smallest opening of the upper end head 1 is smaller than the outer diameter of the thread burial needle.

In this embodiment, it is preferable that the inner diameter of the smallest opening of the lower tip 2 is larger than the outer diameter of the catgut embedding needle.

As can be seen from the cross-sectional view of the threading device shown in fig. 2, the needle body of the thread burial needle 4 can enter the middle channel 3 from the minimum opening of the lower end head 2, and as the inner diameter of the joint of the middle channel 3 and the upper end head 1 is smaller than the outer diameter of the thread burial needle 4, the thread burial needle can be clamped at a position about half of the thread burial needle entering the middle channel 3 under normal conditions, and at the moment, the thread burial needle 4 is fixed and can be used for threading.

In this embodiment, preferably, the thread-embedding needle threading device is made of a plastic material.

It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
