Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a novel freely adjustable surgical retractor for surgery. Background Art

[0002] Surgical retractors are widely used tools in surgery, mainly used to pull and fix tissues in order to provide a clear exposure view for the surgical area. With the advancement of technology, surgical retractors are also constantly innovating. These improvements not only improve the efficiency of surgery, but also reduce the labor intensity of surgeons and improve the overall quality of surgery. However, most surgical retractor structures on the market are still integrated fixed structures, and some retractors use bolts and bolt holes to adjust the position of the retractor, which is troublesome to operate in practice, and the length of the retractor cannot be freely adjusted.

[0003] Now there are some new adjustable retractors that hope to solve this problem, such as the patent publication number CN108433766A discloses a new type of general surgery freely adjustable surgical retractor, which can freely adjust the position of the lateral support to make the hook claw in a suitable position, solving the problem that the bolt-fixed retractor can only be adjusted a certain distance each time, that is, the retractor distance cannot be freely adjusted. However, the device can only adjust the length of the retractor, but not the width of the retractor, and the device needs to be driven by a motor, which is not simple and practical enough.

[0004] Therefore, a new type of surgical retractor is needed now. The device can adjust the length of the retractor according to the needs of the surgical situation, and the device can adjust the width of the retractor according to the type of surgery. Whether it is a thyroid surgery that requires delicate operation or an abdominal surgery that requires a larger operating space, it can provide a suitable retractor width to meet the specific requirements of the surgery. In addition, during the use of the device, the doctor only needs to use a simple adjustment mechanism to extend the length of the retractor. In addition, the retractor can be automatically locked when the retractor is adjusted to a suitable length through a mechanical structure to ensure the stability of the retractor during the operation. Summary of the invention

[0005] In order to solve the above technical problems, the present invention designs a new type of freely adjustable surgical retractor for surgery. The device is provided with four independent retractor components, wherein the retractor components can be folded or unfolded, so that the retractor can be narrowed or widened; in addition, an adjustment block and an adjustment tooth are provided inside the retractor component, and the user only needs to simply turn the adjustment knob 7 connected to the adjustment block to control the adjustment tooth to move forward or backward, thereby driving the telescopic plate connected to the adjustment tooth to move forward or backward; in addition, a spring sheet is rotatably connected to the end of the adjustment tooth, which can ensure that the adjustment tooth is pressed down by the spring sheet after the adjustment is completed, so as to achieve the effect of automatic limit locking. In addition, each retractor component is provided with a folding hook, which can be turned out as needed and can be stored when not needed.

[0027] Example 2

[0028] In this embodiment, the hook assembly is a key part of the device, wherein the housing 101 is the base of the entire hook assembly, which is used to accommodate and protect the internal mechanical structure. Inside the housing 101, an adjustment block 102 is rotatably arranged, and the adjustment block 102 can rotate freely. Two cylindrical card blocks are fixedly arranged inside the housing 101, and the function of the card blocks is to interact with the adjustment teeth 103 to control the movement of the telescopic plate 104. The telescopic plate 104 is slidably sleeved inside the housing 101, allowing it to move back and forth inside the housing 101. The end of the telescopic plate 104 is rotatably connected to the adjustment teeth 103, so that the movement of the telescopic plate 104 can drive the adjustment teeth 103 to move. Several card slots are regularly arranged on the adjustment teeth 103, and these card slots match the cylindrical card blocks inside the adjustment block 102. One end of the spring sheet 106 is rotatably connected to the end of the folding hook 105, and the other end is movably contacted with the inner side of the housing 101. The spring sheet 106 can automatically press down and lock the adjusting tooth 103 after the adjustment is completed, so as to realize the function of automatic limiting. The automatic locking mechanism of the spring sheet 106 not only ensures the stability of the retractor during the operation, but also makes the adjustment process faster and more convenient.

[0029] The folding hook 105 is rotatably connected to the front end of the telescopic plate 104 and can be turned out or stored according to the specific needs of the operation. When the folding hook 105 is turned out, it can provide an additional traction site to enhance the fixation ability of the surgical retractor; when it is not needed, the folding hook 105 can be stored to ensure the compactness of the entire device and will not affect the surgical field of view. This design allows the retractor assembly to meet the functionality while also taking into account the different practical application needs during the operation.

[0030] Example 3

[0031] In this embodiment, in the surgical retractor design of the present invention, a rectangular protrusion 107 is fixedly provided on one side of the adjustment block 102, and a rectangular groove 108 is fixedly provided on the other side. This design allows the rectangular protrusion 107 of one retractor assembly to be inserted into the groove of the other retractor assembly when the two retractor assemblies are folded, so that only the retractor knob of one retractor assembly needs to be controlled to adjust the length of the two retractor assemblies at the same time, thereby improving the practicality and convenience of operation of the surgical retractor.

[0032] Example 4

[0033] In this embodiment, in the design of the surgical hook of the present invention, in order to ensure that the hook assembly can be stably fixed after being adjusted to a specific position to avoid accidental movement during the operation, and at the same time, in order to further enhance the stability and adjustment accuracy of the surgical hook, a limiting plate 8 is rotatably installed on one side of the housing 101 of the first hook assembly 1 and the fourth hook assembly 4, and a limiting groove 9 is provided on one side of the housing 101 of the second hook assembly 2 and the third hook assembly 3. The limiting plate 8 can be rotated into the limiting groove 9 when necessary to fix the position of the hook assembly to ensure that the hook will not move accidentally during the operation.
