Description

Technical Field

[0001] The utility model relates to a surgical tool, in particular to a surgical retractor structure. Background Art

[0002] Surgical retractors are used to pull tissue at the surgical incision to facilitate observation and surgical operations. Traditional retractors are U-shaped, which is not very effective in pulling the skin after incision. Moreover, the U-shaped retractor can easily cause damage to the skin wound. Furthermore, since the length between the retractor and the handle cannot be adjusted, the length cannot be flexibly adjusted during surgery.

[0003] Therefore, existing surgical instruments need to be further improved. Utility Model Content

[0004] The purpose of the utility model is to provide a surgical retractor structure, which changes the U-shaped design of the retractor head into an L-shaped design and can flexibly adjust the length of the retractor to facilitate surgery.

[0005] In order to achieve the above purpose, the present invention adopts the following scheme:

[0006] A surgical retractor structure comprises a handle, wherein a telescopic adjustment structure is provided in the handle, and a right-angle retractor structure is provided on the telescopic adjustment structure.

[0007] Furthermore, the right-angle hook structure includes a flat connecting end, a vertical hook end is provided outside the flat connecting end, and the flat connecting end and the vertical hook end are arranged perpendicular to each other.

[0008] Furthermore, the handle includes a shell, and the outer wall of the shell is provided with anti-slip lines.

[0009] Furthermore, the telescopic adjustment structure includes a telescopic structure arranged in the shell, the shell is provided with an adjustment structure for adjusting the length of the telescopic structure, and a locking structure is provided between the adjustment structure and the shell.

[0010] Furthermore, the telescopic structure includes a central axis hole provided in the middle of the shell, an adjustment shaft body is movably provided in the central axis hole, and the outer end of the adjustment shaft body is fixedly connected to the flat connecting end.

[0011] Furthermore, the adjustment structure includes an opening arranged in the middle of the shell, an annular rotation positioning groove is provided at the opening position, an adjustment ring is rotatably provided in the annular rotation positioning groove, an inner wall of the adjustment ring is provided with an internal thread, and an outer wall of the circumference of the adjustment shaft is provided with an external thread, the adjustment ring is sleeved outside the adjustment shaft body and the internal thread and the external thread are threadedly connected.

[0012] Furthermore, the locking structure includes an elastic latch structure arranged on one side of the opening, and the end surface of the adjustment ring is evenly distributed with multiple positioning holes around the center circumference of the adjustment ring. The elastic latch structure can cooperate with one of the positioning holes and lock the angle of the adjustment ring.

[0013] In summary, the present invention has the following beneficial effects compared to the prior art:

[0014] The present invention solves the shortcomings of existing surgical instruments. Through the structural setting of the present invention, it has the following advantages: the traditional U-shaped retractor head structure is designed as an L-shaped retractor head structure, so that while maintaining the skin retraction function, it can also reduce the damage of retraction of the skin by reducing the structural replicability of the retraction head, ensuring the same function while making the structure simpler. During use, the length of the retractor can be adjusted according to surgical requirements, making it more flexible to use, simple in structure, and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A surgical retractor structure comprises a handle 1, wherein a telescopic adjustment structure 2 is provided in the handle 1, and a right-angle retractor structure 3 is provided on the telescopic adjustment structure 2;

[0022] The traditional U-shaped retractor is changed to an L-shaped right-angle retractor structure 3, which ensures the pulling function while reducing the complexity of the structure and reducing the damage caused by pulling the skin.

[0023] The right-angle hook structure 3 of the present invention includes a flat connecting end 301, a vertical hook end 302 is provided outside the flat connecting end 301, and the flat connecting end 301 and the vertical hook end 302 are arranged perpendicular to each other;

[0024] The vertical retractor end 302 and the flat connecting end 301 are perpendicular to each other and are used for pulling the skin of the surgical opening.

[0025] The handle 1 of the present invention comprises a shell 101, and the outer wall of the shell 101 is provided with anti-slip lines 102;

[0026] The anti-slip lines 102 improve the stability of the handheld hook structure.
