Description

Sewing needle with specific clamping angle and radian

Technical Field

The utility model relates to a seam needle especially relates to a seam needle of specific centre gripping angle and radian.

Background

Surgical needles, which are primarily used for suturing tissue and transfixion ligation, are made of high quality and high tenacity stainless steel and are strong enough to carry suture material through tissue with minimal resistance and minimal tissue drag. In the operation process, the suture angles of incisions at different parts are inconsistent, and the clamping surfaces of the existing operation suture needles are in the same radian, so that the requirements of operators cannot be completely met, and therefore, the suture needle with a specific angle and radian is needed to solve the problem.

Disclosure of Invention

The utility model provides a have specific radian, can adjust the seam needle of centre gripping angle according to different position incisions, it is unanimous to have solved the seam needle clamping surface radian that exists among the prior art, sews up the technical problem who has the degree of difficulty.

The above problems of the present invention are solved by the following technical solutions: the utility model provides a seam needle of specific centre gripping angle and radian, includes syringe needle, needle body and backshank the needle body on be equipped with at least one clamping face, the clamping face is the continuous plane of extending to the backshank from the syringe needle. The needle body is provided with at least one clamping surface, the whole trend of the clamping surface is from the needle head to the needle tail, and the clamping surface is a continuous plane, so that the needle holder can better clamp a sewing needle.

Preferably, the clamping surface is helical. The clamping surface has a spiral angle change, and the requirement of the suture angle of the incisions at different parts is met.

Preferably, the included angle between the clamping surface and the vertical surface close to one end of the needle head is 12 degrees, and the included angle between the clamping surface and the vertical surface close to one end of the needle tail is 15 degrees. The spiral clamping surface of the sewing needle has 12-15 degrees of angle change, and a proper clamping angle can be selected according to incisions at different positions, so that the incision sewing work can be completed more smoothly.

Preferably, the number of the clamping surfaces is two, the two clamping surfaces are parallel to each other, and two ends of the two clamping surfaces are arc surfaces. Two clamping surfaces are parallel to each other, and the both ends of two clamping surfaces are connected through the arc surface, that is to say, two clamping surfaces are the mellow transition, and this has guaranteed the smoothness of needle body, ensures that the condition of scratch tissue can not appear when sewing up the incision in the seam needle.

Preferably, the projection arc length of the needle on the plane is 3 pi r/4, the clamping surface is positioned at one end of the needle body, which is connected with the needle tail, and the length of the clamping surface is 1/5 of the needle body. The projection arc length of the needle on the plane is 3 pi r/4, and the needle can perfectly sew the incision by matching with the spiral clamping surface. The length of the clamping surface is 1/5 of the needle body, which is convenient for the needle holder to clamp.

Therefore, the utility model has the advantages of as follows: the needle holder comprises two clamping surfaces, so that the needle holder can better clamp a sewing needle for sewing; the two clamping surfaces are parallel to each other and connected through the arc surface, so that the smoothness of the surface of the sewing needle is ensured, and the incision can be sewn conveniently; the clamping surface is in a spiral shape, and the included angle between the clamping surface and the vertical surface is changed, so that the proper clamping angle can be selected for sewing according to the incisions of different parts; the projection arc length of the sewing needle on the plane is 3 pi r/4, and the spiral clamping surface is matched, so that the sewing difficulty is reduced.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): a needle with a specific clamping angle and radian as shown in figures 1-2. The needle comprises a needle point 1, a needle body 2 and a needle tail 3, and the projection arc length of the needle on a plane is 3 pi r/4. Two clamping surfaces 3 which are parallel to each other are arranged on the needle body 2, and the two ends of the two clamping surfaces 3 are in transitional connection by an arc surface 5, so that the smoothness of the outer surface of the sewing needle is ensured. The holding surface 3 is located at one end of the needle body 2 close to the needle tail 4, and the length of the holding surface 3 is 1/5 of the needle body 2. Clamping face 3 is the heliciform, and has contained angle change between the vertical face, and the contained angle of clamping face 3 and the vertical face that is close to this end of syringe needle 1 is 12 degrees, and the contained angle of clamping face 3 and the vertical face that is close to this end of backshank 4 is 15 degrees, and such angle change can satisfy the incision of different positions and sew up.
