Description

A pre-wound coil with needle suture

technical field

The utility model belongs to the technical field of medical instruments, in particular to a pre-wound coiled suture thread with a needle.

Background technique

Laparoscopic surgery is widely used in clinical practice due to its advantages of small incision and quick postoperative recovery. However, due to the limitation of operating space and instrument angle, endoscopic knotting is a basic skill that is difficult to master. In response to this problem, many scholars have summarized a lot of knotting skills under endoscopy, but it still requires continuous training to master; there are also many devices or instruments designed to assist knotting (CN205795748U, CN110151242A, CN108618817A), These instruments or devices all have some common problems to varying degrees: first, in the process of endoscopic surgery, the operator needs to change the needle holder or knotted instruments back and forth, which will increase the operation steps and prolong the operation time; second, Many auxiliary devices for knotting are complicated in structure or cumbersome to use, making practical application difficult; thirdly, the use of these devices will increase the economic burden of patients.

The knotting operation can be decomposed into the following steps: clamping the needle (head end) → winding → clamping the thread tail (tail end) → tensioning. Among them, the "winding" step is the most difficult. The reason is that the angle between the two operating instruments is often too small when the endoscope is knotted (when knotting outside the body, the angle between the two instruments is close to a right angle), and the tip of one instrument is difficult to The tip of the other instrument is the center circle; the second is to clamp the needle or thread. The blood exudate makes the needle or thread completely fit the surface of the organ, or because the needle and thread fall into the gap between the organs and tissues, it is difficult to easily and accurately clamp the instrument.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present utility model is to provide a pre-wound stitched thread with needles in view of the above-mentioned problems, which transforms the traditional needles and threads so as to simplify the knotting operation.

The technical solution adopted by the utility model to solve the above technical problems is: a pre-wound coil with needle suture, which is characterized in that it includes a sewing needle, a pre-wound coil and a suture, and the pre-wound coil has a "∞" type structure , which is composed of left and right circular coils, the winding directions of the left and right circular coils are opposite, and the free ends are respectively connected with the sewing needle and the sewing thread.

According to the above solution, a plane angle is set between the left and right circular coils, the plane angle is an obtuse angle, and the outer ends of the left and right circular coils are downward and inner ends are upward.

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

According to the above solution, the diameter of the thread used for the pre-wound coil is the same as the diameter of the suture.

According to the above solution, the inner diameters of the left and right circular coils are smaller than the opening diameter of the forceps and larger than the outer diameter of the forceps occluding.

The beneficial effects of the present invention are: to provide a pre-wound stitching thread with needles, after the needles are added two opposite winding directions and independent of each other, when knotting, the single coil of the flexible pre-wound coil in the "∞" shape is easy to Sliding from the head end to the tail end of the thread simplifies the knotting operation into three steps: gripping the needle (head end) → clamping the thread tail (tail end) → tensioning, reducing the difficulty of knotting and improving the efficiency of knotting There is a flat obtuse angle between the left and right circular coils, and there is a gap between the coil and the surface of the tissues and organs, which is convenient for grasping and saves time and effort.

Detailed ways

In order to better understand the present utility model, the present utility model is further described below with reference to the accompanying drawings and embodiments.

As shown in Figure 1 and Figure 2, a pre-wound coil with needle suture, including needle 1, pre-wound coil and suture 4, the pre-wound coil is "∞" type structure, consisting of a left circle coil 2, a right circle The coil is composed of 3, the left and right circular coils are wound in opposite directions, and the free ends are respectively connected with the sewing needle and the sewing thread.

There is a flat angle between the left and right circular coils, and the flat angle is an obtuse angle. The outer end of the left and right circular coils is downward and the inner end is upward. The left and right circular coils can be distinguished by different colors. At any time, the coil is not completely close to the surface of the organ and tissue, and there is a gap between the coil and the surface of the tissue and organ, which is convenient for the forceps 5 to grasp and lift. During use, the correct position and order of the coils should be ensured, that is, the sharp corners of the coils should be upward, and the forceps should be in the order of first right and then left.

The left and right circular coils are spring wires, which will automatically recover after being straightened. The diameter of the thread used for the pre-winding coil is the same as the diameter of the subsequent suture, and the surface is smooth. When pulling both ends of the coil, the coil will unfold in a straight line, and it will automatically and quickly recover to "∞" when it is released. When sewing, the needle is pulled. , the loop is straightened to pass through the eye of the needle with the needle. The needles and sutures are common endoscopic needles and threads; when in use, the needles at the front end can also be cut off, and only the pre-wound coils and sutures are left for use as ligatures.

The inner diameters of the left and right circular coils are smaller than the opening diameter of the instrument forceps, and larger than the occlusion outer diameter of the instrument forceps. The front end of the surgical instrument is inserted into the coil, the opening is opened, and the coil can be hung on the front end of the instrument, so that the pre-wound coil and sewing needle can be easily lifted.

As shown in Figures 3a, 3b, 3c, and 3d, when in use, the instrument forceps extends into the right circular coil, opens the opening, picks up the head end of the needle thread, and then grabs the end of the thread, and another instrument forceps (not shown in the figure) Grab the stitches. The instrument forceps that grabs the needle is tightened first. At this time, the coil is stretched and straightened, and the winding is slid from the coil to the head end of the thread, and then to the tail end. Tail instrument forceps pull the thread tail through the coil to complete a single knot at the end of the suture. Then in the same way, the instrument forceps extends into the left circular coil, then grabs the end of the thread, and the other instrument forceps grabs the suture needle and pulls it tight to complete a square knot.

The above is the best embodiment of the present invention, and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above examples according to the technical essence of the present invention still fall within the scope of the present invention. within the protection scope of the present invention.
