Description

Semi-heart type suture needle for surgery

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a half heart type suture needle for surgery.

Background

Suture needles are a necessary tool for surgical operations. Suture needles are of many different types depending on the material, cross-sectional shape and curvature of curvature. Among them, the radian of the suture needle is a key index of the suture needle. The suture needles with the circular arcs of 1/4, 3/8, 1/2 and 5/8 which are commonly used at present are formed by cutting different arcs of the circle where the suture needles are located. When in use, the suture needle is matched with the clamping pincers and the rotation of the wrist to carry out suture operation in an operation. The deeper the suture position, the narrower the space, and the smaller the degree of freedom with which the wrist can rotate. With the progress of the micro-pore channel technology and the endoscope technology, the operation in the micro space becomes possible, but with the operation in the micro space becoming possible, the problem of the reduction of the space for the suture operation is brought, and the inconvenience is brought to the operation.

Detailed Description

The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of the invention, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit the scope of the invention.

The utility model discloses a concrete embodiment, as shown in figure 1, discloses a half heart type suture needle (hereinafter referred to as "suture needle") for surgery, including smooth connection's first section 1 and second section 2, first section 1 is the head of suture needle, and second section 2 is the afterbody of suture needle, and first section 1 and second section 2 are arc and the radius of the circle at first section 1 place is less than the radius of the circle at second section 2 place.

Compared with the prior art, the suture needle provided by the embodiment comprises the first section 1 and the second section 2 with different radiuses, the first section 1 and the second section 2 are in smooth transition connection, so that in the suture operation process, the suture path can be subjected to secondary orbital transfer, and the radius of the second section 2 is larger than that of the first section 1, so that when a deeper position is sutured, the wrist of an operator can reach the high-radian curved target of the needle track of the suture needle by only needing small rotation, and the operation in a surgical operation is facilitated.

Specifically, the head of the first section 1 is a needle point 3, the needle point 3 is a puncture part, the tail of the first section 1 is connected with the head of the second section 2, and the tail of the second section 2 is provided with a threading hole 4 for threading a suture.

Further, in order to enable the wrist of the operator to rotate a little to achieve the purpose of high-curvature bending of the needle path of the suture needle when suturing deeper positions, the radius of the second circle where the second section 2 is located is not less than 2 times of the radius of the first circle where the first section 1 is located.

Preferably, the radius of the second section 2 is 3-5 times the radius of the first section 1.

Further, in order to minimize the overall width of the suture needle (the distance from the tail of the second segment 2 to the belly of the first segment 1, h in the drawing) so that the suture needle can be used in a small space, the central angle of the first segment 1 is less than 180 °, and the second segment 2 is also located in the semicircular region of the first circle so that the overall width of the suture needle is not greater than the radius of the first segment 1.

Preferably, the central angle of the first segment 1 is 135-160 °.

Further, in order to make the transition of the first section 1 and the second section 2 easier on the basis of not increasing the overall width of the suture needle, the included angle between the tail of the first section 1 and the head of the second section 2 is avoided to be too small, the processing difficulty is increased, the tail of the second section 2 (namely, the tail of the suture needle) is positioned at the center of a circle where the first section 1 is located, and the overall width of the suture needle is not more than the radius of the first section 1.

In a preferred embodiment of the present invention, as shown in fig. 2, the threading hole 4 is located at the first section 1 and close to the needle tip 3, so that when the suture needle enters a shallow position of the suture site, the suture thread can enter the suture site, thereby facilitating the suture of the wound.

Another preferred embodiment of the present invention, as shown in fig. 3, the suture needle has two threading holes 4, and the two threading holes 4 are respectively located at the tail of the second section 2 and the position of the first section 1 near the needle tip 3, so that the operator can select different threading holes 4 for threading the suture according to different requirements of the operation.

When the suture needle of the embodiment is used, the transition region of the first section 1 and the second section 2 is firstly clamped by the clamping forceps, so that the needlepoint 3 of the suture needle firstly penetrates into the position to be sutured. With the deepening of the suture position, when the operable space is small, the tail part of the suture needle is clamped by the clamping pincers, so that the wrist of an operator only needs to rotate a little to enable the suture needle to rotate in a high radian, and the deeper part can be sutured conveniently.

The utility model provides a half heart type suture needle for surgery includes first section 1 and second section 2 that utensil smooth connection, and the radius of second section 2 is greater than the radius of first section 1 for when sewing up darker position, the needle that operator's wrist only needs less rotation just can reach the suture needle says the crooked target of high radian, makes things convenient for the operation among the surgical operation.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
