Description

Technical Field

[0001] This utility model relates to the technical field of medical devices and related fields, and in particular to a miniature automatic retractor for surgery. Background Technology

[0002] Currently, when treating carpal tunnel syndrome, doctors can make a small incision in the palm to cut the transverse carpal ligament, exposing the median nerve within the carpal tunnel, and then release the median nerve within the carpal tunnel. However, after making the small incision in the palm, it needs to be opened up before subsequent treatment can be performed. Without a suitable retractor or hook, it is difficult for doctors to complete this procedure smoothly. Utility Model Content

[0003] In view of this, and to solve the above problems, the purpose of this utility model is to provide a miniature automatic retractor for surgery, comprising:

[0004] The automatic pull hook is bent in the middle so that it is in a "V" shape;

[0005] Both ends of the automatic hook are bent four times along the X-axis, Y-axis, Z-axis and Y-axis directions to form two hook parts.

[0006] In the aforementioned surgical procedure, a miniature automatic retractor is provided, wherein one end of the automatic retractor is bent four times along the positive X-axis, positive Y-axis, positive Z-axis, and negative Y-axis to form a hook portion, and the other end of the automatic retractor is bent four times along the negative X-axis, positive Y-axis, positive Z-axis, and negative Y-axis to form another hook portion.

[0007] In the aforementioned surgical procedure, a miniature automatic retractor is used, wherein the bending angle is approximately 90° each time.

[0008] The aforementioned miniature automatic retractor for surgery has a curved section at its midpoint.

[0009] The aforementioned miniature automatic retractor for surgery has two hooks with arc-shaped ends.

[0010] The positive effects of the above technical solution compared with the existing technology are:

[0011] By applying this utility model, a miniature automatic retractor is provided for surgery. This device opens the incision in the palm, making the surgical incision smaller, allowing doctors to complete the surgery independently, shortening the operation time, effectively reducing complications, and ensuring the safety and reliability of the surgery.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0017] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0018] like Figures 1 to 3 As shown, a preferred embodiment of a surgical miniature automatic retractor is illustrated, comprising: the device forming an automatic retractor structure by repeatedly bending an existing Kirschner wire or steel wire.

[0019] The automatic hook 1 is bent in the middle so that the automatic hook 1 is in a "V" shape; then both ends of the automatic hook 1 are bent four times along the X-axis, Y-axis, Z-axis and Y-axis respectively to form the hook part 2 of the automatic hook 1.

[0020] In actual use, the doctor first makes a longitudinal incision in the palm of the hand, about 2 cm long. Then, the hook part 2 of the automatic retractor 1 is inserted into the incision at one edge of the incision. The automatic retractor 1 is located outside the incision. Because the automatic retractor 1 is made of stainless steel, it has a certain degree of elasticity. When the hook part 2 of the automatic retractor 1 is inserted into the incision, it can open the incision, keeping the incision open. The doctor can then proceed with the subsequent surgical steps, which helps the doctor to perform the surgery independently.

[0021] Based on the above, this utility model also has the following embodiments:

[0022] In the aforementioned surgical procedure, a miniature automatic retractor 1 has one end forming a retractor 2 by bending four times sequentially along the positive X-axis, positive Y-axis, positive Z-axis, and negative Y-axis. The other end of the automatic retractor 1 forms another hook 2 by bending four times sequentially along the negative X-axis, positive Y-axis, positive Z-axis, and negative Y-axis. Specifically, the automatic retractor 1 extends outward along the X-axis, the Y-axis is perpendicular to the X-axis, and the Z-axis is perpendicular to both the X and Y axes. Both ends of the automatic retractor 1 first bend towards either the positive or negative X-axis, then bend a second time towards the positive Y-axis, then a third time towards the positive Z-axis, and finally bend a final time towards the negative Y-axis.

[0023] Furthermore, a miniature automatic retractor for surgery, wherein each bending angle is approximately 90°.

[0024] Furthermore, a miniature automatic retractor for surgery, wherein the middle bend of the automatic retractor 1 is set in an arc.

[0025] Furthermore, a miniature automatic retractor for surgery has two hook portions 2 with arc-shaped ends. Specifically, the arc-shaped ends of the two hook portions 2 prevent secondary damage to the incision.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
