Description

Pre-wound coil suture with needle

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a coil area suture in advance.

Background

The endoscopic surgery has the advantages of small surgical incision, quick postoperative recovery and the like, and is widely applied clinically, but the knotting under the endoscope is a basic skill which is difficult to master due to the limitation of the operation space and the angle of the instrument. Aiming at the problem, a plurality of scholars summarize and summarize a plurality of skills for knotting under the endoscope, but the skill still needs to be trained continuously to master; there are also numerous knotting-assisted devices or instruments designed (CN205795748U, CN110151242A, CN108618817A), which have some common problems to different degrees: firstly, in the process of endoscopic surgery, an operator needs to change a needle holder or a knotting instrument back and forth, so that the operation steps are increased, and the time for surgery is prolonged; secondly, many knotting auxiliary instruments are complex in structure or cumbersome to use, and difficult to apply practically; third, the use of these devices increases the economic burden on the patient.

The knotting operation can be broken down into the following steps: holding the needle (head end) → winding → holding the tail (tail end) → tensioning. The reason for the most difficult winding step is that when the endoscope is knotted, the included angle between two operating instruments is often too small (when the endoscope is knotted in vitro, the included angle between the two instruments is close to a right angle), and the tip of one instrument is difficult to wind around the tip of the other instrument; secondly, the needle or the thread is clamped, and the blood effusion makes the needle or the thread completely attached to the surface of the organ or the needle and the thread fall into the gap of the organ tissue, so that the apparatus is difficult to clamp easily and accurately.

Disclosure of Invention

The utility model aims to solve the technical problem that to the problem that above-mentioned exists, provide a coil area sewing line in advance, reform transform traditional sewing line for the operation of knoing is simplified.

The utility model provides a technical scheme that above-mentioned technical problem adopted is: the utility model provides a pre-wound coil area needle suture, its characterized in that includes the stitch, pre-wound coil and suture, pre-wound coil is "∞" type structure, comprises left and right circle coil, the winding of left and right circle coil is opposite, free end respectively with stitch and suture link to each other.

According to the scheme, a plane included angle is arranged between the left circular coil and the right circular coil, the plane included angle is an obtuse angle, and the outer side ends of the left circular coil and the right circular coil are upward towards the lower inner side ends.

According to the scheme, the left and right circular coils are spring wires and can automatically recover after being straightened.

According to the scheme, the diameter of the wire used by the pre-wound coil is the same as that of the suture.

According to the scheme, the inner diameter of the left and right circular coils is smaller than the opening caliber of the instrument forceps and larger than the occlusion outer diameter of the instrument forceps.

The invention has the beneficial effects that: the utility model provides a prewound coil takes needle suture, add two after the sewing needle and wind to opposite and mutual independence, when knoing, be the single coil of the flexible prewound coil of "∞" type easily from the head end slip to the tail end of line for the knotting operation simplifies to three steps: the clamping suture needle (head end) → clamping the thread tail (tail end) → tensioning, so that the knotting difficulty is reduced, and the knotting efficiency is improved; a plane obtuse angle is arranged between the left circular coil and the right circular coil, a gap exists between the coils and the surface of the tissue organ, grabbing is facilitated, and time and labor are saved.

Detailed Description

For a better understanding of the present invention, the following further description of the present invention is made with reference to the accompanying drawings and examples.

As shown in figures 1 and 2, the pre-wound coil suture with the needle comprises a suture needle 1, a pre-wound coil and a suture 4, wherein the pre-wound coil is of an infinity-shaped structure and consists of a left circular coil 2 and a right circular coil 3, the winding directions of the left circular coil and the right circular coil are opposite, and the free end ends are respectively connected with the suture needle and the suture.

A plane included angle is arranged between the left circular coil and the right circular coil, the plane included angle is an obtuse angle, the outer side ends of the left circular coil and the right circular coil face upwards towards the lower inner side ends, and the left circular coil and the right circular coil can be distinguished by different colors. At any time, the coil is not completely attached to the surface of the organ tissue, and a gap is formed between the coil and the surface of the organ tissue, so that the instrument forceps 5 can be conveniently grabbed and lifted. In the using process, the correct position and sequence of the coil are ensured, namely the sharp angle of the coil is upward, and the forceps are sequentially arranged from right to left.

The left and right round coils are spring wires and can automatically recover after being straightened. The diameter of the thread used by the pre-winding coil is the same as that of the subsequent suture, the surface is smooth, when two ends of the coil are pulled, the coil is unfolded to be in a straight line, the infinity is automatically and rapidly recovered when the coil is loosened, when the suture is sewed, the suture needle is pulled, and the coil is straightened so as to pass through a needle eye along with the needle. The sewing needle and the suture are needles and threads for common endoscope; in use, the needle at the front end may also be cut away, leaving only the pre-wound coil and suture to be used as a ligature.

The inner diameters of the left and right circular coils are smaller than the opening caliber of the forceps and larger than the occluding outer diameter of the forceps. The front end of the surgical instrument extends into the coil, the opening is opened, and the coil can be hung at the front end of the surgical instrument, so that the pre-wound coil and the sewing needle can be easily picked up.

In use, as shown in fig. 3a, 3b, 3c and 3d, the forceps are inserted into the right circular loop, the opening is opened, the needle thread end is picked up, the thread tail is picked up, and the other forceps (not shown) is used for picking up the suture needle. The instrument forceps for grabbing the suture needle are firstly tightened, at the moment, the coil is unfolded and straightened, the winding wire slides to the head end of the thread from the coil and then slides to the tail end, the suture slides to the tail end of the thread, the instrument forceps for grabbing the tail end of the thread pull the tail end of the thread from the coil, and a single knot is tied at the tail end of the thread. Then, in the same method, the instrument forceps extend into the left round coil, then the wire tail is grabbed, the other instrument forceps grab the suture needle and are tensioned, and then a square knot is knotted.

The above description is the best embodiment of the present invention, not to the limitation of the present invention in any form, and all the technical matters of the present invention are any simple modification, equivalent change and modification made to the above examples, and all still fall into the protection scope of the present invention.
