Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a puncture suturing needle used in deep and narrow spaces. Background Art

[0002] Suture needles are a common type of surgical instrument, mainly used to puncture tissues, suture tissues, close wounds, and ligate tissues. Usually, the suture needle needs to be clamped by a needle holder and then rotated to puncture through the tissue. In a deep and narrow space, the needle holder is difficult to rotate, and the suture needle is not easy to adjust to the appropriate angle to pass through the tissue, resulting in the inability to suture the tissue, which causes poor wound healing. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a puncture suture needle for deep and narrow spaces.

[0004] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0005] A puncture suture needle for deep and narrow spaces, comprising a connecting handle, wherein the upper end of the connecting handle is provided with a suture hook needle, and the lower end of the connecting handle is provided with a suture straight needle;

[0006] The suture hook comprises a first rod portion arranged at the upper end of the connecting handle, a bending portion is arranged at the upper end of the first rod portion, a first needle eye is arranged in the transverse direction of the bending portion, a first needle tip is arranged at one end of the bending portion away from the first rod portion, and the first needle tip is located at the side of the first rod portion;

[0007] The straight suture needle comprises a second rod portion arranged at the lower end of the connecting handle, a second needle eye is arranged in the transverse direction of the second rod portion, and a second needle tip is arranged at the lower end of the second rod portion.

[0008] Optionally, the connecting handle has a diameter of 0.4-0.7 mm and a length of 10-16 mm, and the diameters of the first needle eye and the second needle eye are both 0.12-0.4 mm.

[0009] Optionally, the diameter of the suture hook needle and the suture straight needle are both 0.3-0.6 mm, the length is 24-48 mm, and the turning angle of the bending portion is 180°.

[0010] Optionally, the connecting handle includes a column, which is installed between the first rod portion and the second rod portion. Anti-slip patterns are arranged on the periphery of the column, and the anti-slip patterns 102 are oblique grid patterns.

[0011] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0012] 1. The puncture suture needle changes the traditional rotation suturing method into a linear reciprocating method from inside to outside or from outside to inside, with a rotation radius of 0, which saves suturing space and makes it easier to operate on wounds in deep and narrow spaces.

[0013] 2. By designing the first needle eye near the first needle tip and the second needle eye near the second needle tip, the suture can be passed through the tissue without excessive penetration of the tissue, thereby reducing the damage to the tissue caused by puncture and suture.

[0014] 3. The connecting handle can be used for needle holding and can be axially rotated to multiple angles for adjustment.

[0015] 4. The puncture suture needle or the first needle eye and the second needle eye can be designed with different sizes and specifications, and suitable sutures can be selected for suturing according to the wound edge tissue, which has strong universal practicality.

[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
