DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-6The utility model provides the following technical solutions: a fine-adjustable surgical retractor, comprising a main body 3, one end of the main body 3 is connected to a gripping portion 4, an anti-slip component 5 is arranged on the outer side wall of the gripping portion 4 at one end away from the main body 3, a retractor 6 is arranged at the other end of the main body 3, a fine-adjustment mechanism 1 is arranged between the main body 3 and the retractor 6, and a driving component 2 is arranged between the main body 3 and the fine-adjustment mechanism 1.

[0025] Specifically, the anti-slip component 5 includes an anti-slip cover 51, a through hole 52, a sweat-absorbent cotton ring 53, an end ring 54 and a limiter 55. The anti-slip cover 51 is connected to the outer wall of the end of the gripping part 4 away from the main body 3. The anti-slip cover 51 is provided with a plurality of through holes 52. The sweat-absorbent cotton ring 53 is provided inside the anti-slip cover 51 and located on the periphery of the gripping part 4. An end ring 54 is provided at one end of the anti-slip cover 51. A limiter 55 is provided on the side wall of the end ring 54 and located on the periphery of the sweat-absorbent cotton ring 53.

[0026] By adopting the above technical solution, the sweat-absorbent cotton ring 53 is inserted into one side of the end ring 54, and then the end ring 54 is installed to one end of the anti-slip cover 51, and the sweat-absorbent cotton ring 53 is then inserted into the inside of the anti-slip cover 51. When the operator needs to use the entire device later, he / she holds the anti-slip cover 51 to apply force to control the entire device. During the force application process, when the operator's hands sweat, the sweat drips onto the sweat-absorbent cotton ring 53 through the through hole 52 and is absorbed and dried by the sweat-absorbent cotton ring 53, thereby preventing the operator's hands from slipping due to sweating and ensuring the stability of the operator's holding and using the entire device.

[0027] Specifically, an annular groove is provided at one end of the anti-slip sleeve 51 and at a position corresponding to the end ring 54 , and a magnetic ring is connected to the side where the end ring 54 and the annular groove are close to each other.

[0028] By adopting the above technical solution, after the end ring 54 is placed inside the annular groove, the magnetic ring on the side wall of the annular groove and the magnetic ring on the side wall of the end ring 54 are adsorbed and fixed to each other, and then the end ring 54 can be limited and fixed to ensure the stability of the installation of the end ring 54 and the anti-slip sleeve 51.

[0029] Specifically, the limiting member 55 includes an inner ring body 551, an outer ring body 552, a locking block 553, a moving rod 554, a groove 555 and a connecting spring 556. The outer ring body 552 is connected to the side wall of the end ring 54 and is located on the periphery of the sweat-absorbent cotton ring 53. The inner ring body 551 is connected to the side wall of the end ring 54 and is located inside the outer ring body 552. The inner ring body 551 and the outer ring body 552 are both provided with grooves 555 on one side close to the sweat-absorbent cotton ring 53. The moving rod 554 is inserted into the inside of the groove 555. A connecting spring 556 is connected between the moving rod 554 and the groove 555. The end of the moving rod 554 away from the connecting spring 556 is connected to the locking block 553.

[0030] By adopting the above technical solution, the sweat-absorbent cotton ring 53 is inserted between the inner ring body 551 and the outer ring body 552. During the insertion process, the tightening block 553 moves due to the squeezing effect of the sweat-absorbent cotton ring 53. The movement of the tightening block 553 drives the moving rod 554 to move inside the groove 555. The moving rod 554 moves to squeeze the connecting spring 556. Under the action of the tightening block 553, the sweat-absorbent cotton ring 53 can be tightened and fixed to ensure the stability of the placement of the sweat-absorbent cotton ring 53.

[0031] Specifically, both sides of one end of the moving rod 554 close to the groove 555 are connected to limit sliders, and a limit sliding groove is provided on the inner side wall of the groove 555 at a position corresponding to the limit slider.

[0032] By adopting the above technical solution, the movement of the moving rod 554 drives the limiting slider to move inside the limiting slide groove. When the limiting slider moves to fit the side wall of the limiting slide groove, the limiting slider is blocked and stops moving, thereby preventing the moving rod 554 from continuing to move and preventing the moving rod 554 from escaping the groove 555.

[0033] When the present embodiment is used, the sweat-absorbent cotton ring 53 is inserted between the inner ring body 551 and the outer ring body 552. During the insertion process, the pressing block 553 is squeezed by the sweat-absorbent cotton ring 53 and moves. The movement of the pressing block 553 drives the moving rod 554 to move inside the groove 555. The moving rod 554 moves to squeeze the connecting spring 556. Under the action of the pressing block 553, the sweat-absorbent cotton ring 53 can be pressed and fixed. Then the end ring 54 is installed to one end of the anti-slip sleeve 51. The sweat-absorbent cotton ring 53 is then inserted into the anti-slip sleeve 51. When the operator needs to use the entire device later, he or she can hold the anti-slip sleeve 51 to apply force and control it. During the force application process of the entire device, when the operator's hands sweat, the sweat drips onto the sweat-absorbing cotton ring 53 through the through hole 52 and is absorbed and dried by the sweat-absorbing cotton ring 53, thereby preventing the operator's hands from slipping due to sweating and ensuring the stability of the operator in holding and using the entire device. During medical cosmetic surgeries such as facial lifting or contour adjustment around the eyes, when the entire device needs to be used to assist in surgical suturing operations, the operator first uses the fine-tuning mechanism 1 to adjust the angle between the retractor 6 and the main body 3, and then holds the anti-slip sleeve 51 in the hand to apply force to drive the retractor 6 to open the patient's wound, making it easier for the operator to observe the wound and thus facilitate the wound suturing operation.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that the driving component 2 includes a first gear 21, a mounting frame 22, a second gear 23, a rotating shaft 24 and a rotating rod 25, the first gear 21 is connected to the outer wall of the fine-tuning mechanism 1, the mounting frame 22 is connected above the body 3 and on one side of the first gear 21, the interior of the mounting frame 22 is connected to the rotating shaft 24, the outer wall of the rotating shaft 24 is connected to the second gear 23, and one end of the rotating shaft 24 is connected to the rotating rod 25.

[0036] When this embodiment is in use, the rotating rod 25 is held by hand and force is applied to drive the rotating rod 25 to rotate. The rotation of the rotating rod 25 drives the rotating shaft 24 to rotate. The rotation of the rotating shaft 24 drives the second gear 23 to rotate. The rotation of the second gear 23 drives the first gear 21 to rotate. The rotation of the first gear 21 drives the components in the fine-tuning mechanism 1 to rotate, thereby realizing the operation of the fine-tuning mechanism 1, thereby facilitating the operator to adjust the angle between the hook 6 and the body 3.

[0037] The structure and principle of the fine-adjustment mechanism 1 composed of a connecting head, a first movable rod, a second movable rod, a driving sleeve, and a hinge head in the utility model have been disclosed in a surgical retractor disclosed in Chinese patent application No. 202321489267.2, and its working principle is: the retractor 6 is connected to the main body 3 by a hinge, and a connecting head is connected to the top of the retractor 6, and a hinge head is connected to the top of the connecting head and the main body 3, and the first movable rod and the second movable rod are respectively connected to the sides of the two hinge heads close to each other, and a driving sleeve is connected between the first movable rod and the second movable rod. When the driving sleeve is rotated clockwise, the first movable rod and the second movable rod both move toward the driving sleeve, and the movement of the first movable rod and the second movable rod drives the hinge head to move, and the retractor 6 rotates under the action of the hinge under the action of the hinge head, so that the angle between the retractor 6 and the main body 3 can be adjusted.

[0038] The working principle and use process of the present invention are as follows: the present invention inserts the sweat-absorbent cotton ring 53 between the inner ring body 551 and the outer ring body 552. During the insertion process, the pressing block 553 is squeezed by the sweat-absorbent cotton ring 53 and moves. The movement of the pressing block 553 drives the moving rod 554 to move inside the groove 555. The moving rod 554 moves and squeezes the connecting spring 556. Under the action of the pressing block 553, the sweat-absorbent cotton ring 53 can be pressed and fixed. Then the end ring 54 is installed to one end of the anti-slip sleeve 51. The sweat-absorbent cotton ring 53 is then inserted into the anti-slip sleeve 51. When the operator needs to use the entire device later, he / she holds the anti-slip sleeve 51 and applies force to control the entire device. During the force application process, when the operator's hands sweat, sweat drips onto the sweat-absorbent cotton ring 53 through the through hole 52 and is absorbed and dried by the sweat-absorbent cotton ring 53. The operator's hands are prevented from slipping due to sweating, and the stability of the operator's holding the entire device is ensured. During medical cosmetic surgeries such as face lifting or contour adjustment around the eyes, when the entire device needs to be used to assist in surgical suturing operations, the operator first holds the rotating rod 25 and applies force to drive the rotating rod 25 to rotate. The rotation of the rotating rod 25 drives the rotating shaft 24 to rotate. The rotation of the rotating shaft 24 drives the second gear 23 to rotate. The rotation of the second gear 23 drives the first gear 21 to rotate. The rotation of the first gear 21 drives the components in the fine-tuning mechanism 1 to rotate, thereby realizing the operation of the fine-tuning mechanism 1, thereby facilitating the operator to adjust the angle between the retractor 6 and the body 3. Then, the operator holds the anti-slip sleeve 51 and applies force to drive the retractor 6 to pull open the patient's wound, making it convenient for the operator to observe the wound, thereby facilitating the wound suturing operation.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
