[0015] Beneficial effects:

[0016] Before use, the present invention can start the first cylinder, and the output end of the first cylinder can drive the moving rod to move. Because the outer side of the moving rod is fixedly connected to the push plate, the outer side of the push plate is rotatably connected to the first connecting rod, the outer side of the first connecting rod is rotatably connected to the second connecting rod, and the guide groove provided on the inner side of the housing has a limiting and guiding effect on the second connecting rod, the second connecting rod and the adjustment plate fixedly connected to the outer side of the second connecting rod can be driven to slide along the guide groove, thereby changing the circumferential position of multiple adjustment plates. The present invention can change the circumferential position of multiple adjustment plates, making it convenient for medical personnel with different palm sizes to use by holding the adjustment plate, thereby avoiding the phenomenon of surgical dissectors falling off due to different palm sizes during long operations.

[0017] In the process of pushing the moving rod to move and change the position of the adjustment plate, the first cylinder of the present invention can drive the first rotating shaft to rotate inside the support seat because one end of the moving rod is fixedly connected to a rack, the outer side of the rack is meshed with a spur gear, and the inner side of the spur gear is fixedly connected to the first rotating shaft. In addition, the outer side of the first rotating shaft is fixedly connected to the first limiting arm, so it can drive the first limiting arm to rotate. When the adjustment plate moves outward, the first limiting arm rotates in a direction away from the adjustment plate, so that the first limiting arm can rotate synchronously during the movement of the adjustment plate, making it convenient for the first limiting arm to limit the base of the palm of the medical staff. The present invention is provided with a linkage structure, which can synchronously rotate the first limiting arm while changing the position of the adjustment plate, avoiding the situation where the limiting slot between the adjustment plate and the first limiting arm is reduced after the adjustment plate expands outward, making it impossible to pass through the limiting slot to hold the adjustment plate, so that the first limiting arm can limit the base of the palm of the medical staff.

[0018] According to the present invention, after the position of the adjustment plate and the first limiting arm is adjusted, the medical staff can hold the adjustment plate and then start the drive motor. The output end of the drive motor can drive the worm to rotate. The outer side of the worm is meshed with a worm wheel, and the inner side of the worm wheel is fixedly connected to the second rotating shaft, so that the second rotating shaft can be driven to rotate. In addition, the outer side of the second rotating shaft is fixedly connected to the second limiting arm, so that the second limiting arm can rotate downward along with the second rotating shaft, so that the second limiting arm can fit the back of the medical staff's hand. Moreover, during the downward movement of the second limiting arm, multiple rubber ball heads can effectively contact different positions of the back of the medical staff's hand under the action of the spring and the telescopic shaft. In addition, the structure of the worm wheel and worm transmission has a self-locking effect, so that the rubber ball heads can effectively contact and limit the back of the medical staff's hand. The present invention can effectively limit the back of the medical staff's hand, and combined with the tiger's mouth limiting structure, the medical staff can firmly grasp the dissector, which is conducive to the operation.

[0019] After effectively limiting the hand of the medical staff, the present invention can start the second cylinder. The output end of the second cylinder can drive the mounting plate to move, and the surgical scalpel is fixedly connected to the mounting plate, thereby being able to change the length of the surgical scalpel according to the needs of surgical use. In addition, during the movement of the surgical scalpel, a laser lamp is fixedly installed on the inner side of the mounting plate. The laser lamp emits laser light and passes through the glass window, allowing the medical staff to accurately adjust the length of the surgical scalpel according to the scale. In addition, after the length of the surgical scalpel is adjusted, the electromagnet is energized and generates magnetism to adsorb and fix the surgical scalpel made of metal, thereby locking the surgical scalpel. The present invention can effectively and accurately adjust the length of the surgical scalpel according to the needs of the surgery, and can lock the adjusted surgical scalpel to prevent the movable surgical scalpel from affecting the medical staff's surgical operation.

[0020] In addition to the aforementioned functions, the present invention also features an illuminating lamp that illuminates the surgical site during surgery, with a glass cover protecting the lamp. Furthermore, the fixing bolts can be screwed out from the rear cover and the interior of the housing, allowing the rear cover to be removed from the housing for easy maintenance. This present invention offers multiple functions and is highly practical.

[0058] In this embodiment, a lighting lamp 8 is fixedly mounted on one end of the housing 1 , a glass cover 7 is fixedly connected to the outer side of the housing 1 , and the lighting lamp 8 is located inside the glass cover 7 .

[0060] Working principle:

[0061] Step 1: Before use, the present invention can be activated by starting the first cylinder 501. The output end of the first cylinder 501 can drive the moving rod 502 to move. Because the outer side of the moving rod 502 is fixedly connected to the push plate 503, the outer side of the push plate 503 is rotatably connected to the first connecting rod 504, and the outer side of the first connecting rod 504 is rotatably connected to the second connecting rod 505, and the guide groove 507 provided on the inner side of the housing 1 has a limiting and guiding effect on the second connecting rod 505, it can drive the second connecting rod 505 and the adjustment plate 506 fixedly connected to the outer side of the second connecting rod 505 to slide along the guide groove 507, thereby changing the circumferential position of the multiple adjustment plates 506. The present invention can change the circumferential position of the multiple adjustment plates 506, making it easier for medical personnel with different hand sizes to use by holding the adjustment plates 506, thus preventing the surgical dissector from falling off due to different hand sizes during long surgeries.

[0062] Step 2: When the first cylinder 501 of the present invention pushes the moving rod 502 to move and change the position of the adjustment plate 506, because one end of the moving rod 502 is fixedly connected to a rack 508, the outer side of the rack 508 is meshed with a spur gear 509, and the inner side of the spur gear 509 is fixedly connected to the first rotating shaft 510, the first rotating shaft 510 can be driven to rotate inside the support base 511. In addition, the outer side of the first rotating shaft 510 is fixedly connected to the first limiting arm 512, so the first limiting arm 512 can be driven to rotate. When the adjustment plate 506 moves outward, the first limiting arm 512 rotates in the direction away from the adjustment plate 506, so that the first limiting arm 512 can rotate synchronously during the movement of the adjustment plate 506, making it convenient for the first limiting arm 512 to limit the base of the palm of the medical staff. The present invention is provided with a linkage structure, which can synchronously rotate the first limiting arm 512 while changing the position of the adjustment plate 506, thereby avoiding the situation where the limiting groove 514 between the adjustment plate 506 and the first limiting arm 512 shrinks after the adjustment plate 506 expands outward, making it impossible to grasp the adjustment plate 506 through the limiting groove 514, so that the first limiting arm 512 can limit the base of the palm of the medical staff.

[0063] Step 3: After adjusting the position of the adjustment plate 506 and the first limiting arm 512, the medical staff can hold the adjustment plate 506 and start the drive motor 516. The output end of the drive motor 516 can drive the worm 517 to rotate. The outer side of the worm 517 is meshed with a worm gear 518, and the inner side of the worm gear 518 is fixedly connected to the second rotating shaft 519, thereby driving the second rotating shaft 519 to rotate. In addition, the outer side of the second rotating shaft 519 is fixedly connected to the second limiting arm 520, allowing the second limiting arm 520 to rotate downward along with the second rotating shaft 519, so that the second limiting arm 520 can fit the back of the medical staff's hand. Moreover, during the downward movement of the second limiting arm 520, the multiple rubber ball heads 525, under the action of the spring 524 and the telescopic shaft 523, can effectively contact different positions on the back of the medical staff's hand. In addition, the transmission structure of the worm gear 518 and the worm 517 has a self-locking effect, which allows the rubber ball heads 525 to effectively contact and limit the back of the medical staff's hand. The present invention can effectively limit the back of the hand of medical personnel, and cooperates with the tiger's mouth limiting structure to enable medical personnel to firmly grasp the dissector, which is beneficial to the operation.

[0064] Step 4: After effectively limiting the medical staff's hands, the present invention can start the second cylinder 602. The output end of the second cylinder 602 can drive the mounting plate 603 to move, and the surgical scalpel 4 is fixedly connected to the mounting plate 603, thereby being able to change the length of the surgical scalpel 4 according to the needs of the operation. In addition, during the movement of the surgical scalpel 4, a laser light 604 is fixedly installed on the inner side of the mounting plate 603. The laser light 604 emits laser light and passes through the glass window 605, allowing the medical staff to accurately adjust the length of the surgical scalpel 4 according to the scale 606. In addition, when the length of the surgical scalpel 4 is adjusted, the electromagnet 607 is energized and generates magnetism to adsorb and fix the metal surgical scalpel 4, thereby locking the surgical scalpel 4. The present invention can effectively and accurately adjust the length of the surgical scalpel 4 according to the needs of the operation, and can lock the adjusted surgical scalpel 4 to prevent the moving surgical scalpel 4 from affecting the medical staff's surgical operation.

[0065] Step 5: In addition to the aforementioned functions, the present invention can also activate the illumination lamp 8 during surgery to illuminate the surgical site. The glass cover 7 outside the illumination lamp 8 also protects the illumination lamp 8. Furthermore, the fixing bolt 3 can be screwed out from the interior of the rear cover 2 and the housing 1, allowing the rear cover 2 to be removed from the housing 1, facilitating subsequent maintenance. This present invention has multiple functions and is highly practical.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
