[0027] Example, by Figure 1-9 The utility model comprises a mounting seat 1 which is detachably mounted on the side of the operating table, a height adjustment rod 2 is fixedly mounted on the top of the mounting seat 1, an adjustment arm 3 is fixedly connected to the top of the height adjustment rod 2, and a clamping assembly 4 is detachably mounted on the end of the adjustment arm 3;

[0028] The clamping assembly 4 includes an adapter 41 and an adjustment plate 44. The left and right sides of the adapter 41 are respectively fixedly mounted with a threaded sleeve 42 and a fixed column 43. The left and right sides of the adjustment plate 44 are respectively fixedly mounted with a sliding sleeve 45 and a mounting sleeve 46. A threaded rod 48 is rotatably mounted inside the mounting sleeve 46. One end of the threaded rod 48 is connected to the inner thread of the threaded sleeve 42. A rotating handle 49 is fixedly mounted on the other end of the threaded rod 48. A sliding rod 47 is fixedly mounted on one end of the fixed column 43. The sliding rod 47 is movably sleeved inside the sliding sleeve 45. The bottoms of the adapter 41 and the adjustment plate 44 are both threadedly mounted with a fastening plate 410. The handheld portion of the retractor body 5 is fixedly mounted between the fastening plate 410 and the bottom surface of the adapter 41 and between the fastening plate 410 and the bottom surface of the adjustment plate 44 through two fastening plates 410, respectively.

[0029] In this embodiment, the clamping assembly 4 can cooperate with the scissors-like medical device to clamp the hand-held part of the retractor body 5 to replace the assistant's hand-holding. In addition, the mounting base 1, the height adjustment rod 2 and the adjustment arm 3 cooperate to fix the position of the clamping assembly 4, so that the clamping assembly 4 can be clamped at multiple angles and positions. In addition, different dedicated clamping devices can be developed according to different types of medical devices and directly replaced with the clamping assembly 4 to increase the scope of use of the device.

[0030] By rotating the rotating handle 49, the distance between the adapter 41 and the adjusting plate 44 can be adjusted, so that the opening and closing angle of the retractor body 5 can be adjusted, which is convenient for adjustment during surgery.

[0031] The mounting base 1 includes a U-shaped slider 11, which is movably sleeved on the side plate of the operating table. A cylindrical protrusion 12 is integrally formed on the side of the U-shaped slider 11, and a hand bolt 13 is threadedly installed on the side of the cylindrical protrusion 12. A movable groove 14 is formed on the inner wall of the U-shaped slider 11, and an extrusion plate 15 is movably installed inside the movable groove 14. One end of the hand bolt 13 is in contact with the side of the extrusion plate 15, and the side of the extrusion plate 15 is in contact with the side plate of the operating table.

[0032] In this embodiment, some electric operating tables have stainless steel side panels reserved on the sides for easy installation of various devices. The U-shaped slider 11 is used to cooperate with the side panel, and the squeezing plate 15 is squeezed by turning the hand-tightening bolt 13 to determine the position of the U-shaped slider 11.

[0033] The height adjustment rod 2 includes a fixed sleeve 21, which is fixedly installed on the top of the U-shaped slider 11. A lifting inner cylinder 22 is movably sleeved on the top of the fixed sleeve 21. A side groove 23 is provided on the side of the fixed sleeve 21. A threaded column 24 is fixedly installed on the side of the lifting inner cylinder 22. The threaded column 24 is movably installed in the side groove 23. An arc-shaped extrusion plate 25 is movably sleeved on the surface of the threaded column 24. The side of the arc-shaped extrusion plate 25 fits with the surface of the fixed sleeve 21. A hand-tightening nut 26 is threadedly installed on the surface of the threaded column 24. The side of the hand-tightening nut 26 fits with the side of the arc-shaped extrusion plate 25.

[0034] In this embodiment, since the patient has different postures during the operation, the mattress needs to be adjusted. After the adjustment, the distance between the mattress and the side panels is larger, so the top height of the lifting inner cylinder 22 needs to be adjusted and the lifting inner cylinder 22 is fixed using the hand-tightening nut 26.

[0035] The adjusting arm 3 includes a universal connecting seat 31, a universal connecting piece 32 and a universal extension rod 33. There are two universal connecting seats 31, and the number of universal connecting pieces 32 is one more than the number of universal extension rods 33. The universal connecting seat 31 and the universal extension rod 33 are detachably connected via the universal connecting piece 32, and the universal extension rods 33 and the universal extension rods 33 are detachably connected via the universal connecting piece 32.

[0036] The universal connection seat 31 includes a first mounting ball 311, a first circular plate 313 is fixedly mounted on the bottom of the first mounting ball 311 through a first connecting column 312, a transfer nut 314 is fixedly mounted on the bottom of the first circular plate 313, and the transfer nut 314 is threadedly connected to the top of the lifting inner cylinder 22;

[0037] The universal extension rod 33 includes a smooth rod 331 , and both ends of the smooth rod 331 are fixedly mounted with second mounting balls 333 via second connecting columns 332 ;

[0038] The universal connector 32 includes a first buckle plate 321 and a second buckle plate 322. The first mounting ball 311 and the second mounting ball 333 are both movably mounted between the first buckle plate 321 and the second buckle plate 322. A threaded seat 323 is fixedly mounted on the inner wall of the first buckle plate 321. A hand screw 324 is movably sleeved on the side of the second buckle plate 322. One end of the hand screw 324 is threadedly connected to the threaded seat 323.

[0039] The surfaces of the first installation ball 311 and the second installation ball 333 are both inlaid with anti-slip rubber strips 34 .

[0040] In this embodiment, the number of universal extension rods 33 can be adjusted arbitrarily according to the position of the clamping assembly 4, and the posture of the adjustment arm 3 can be adjusted to avoid affecting the operation of the attending physician. Tightening the hand screw 324 can adjust the distance between the first buckle plate 321 and the second buckle plate 322, thereby clamping the second mounting ball 333 or the first mounting ball 311 to achieve a connection effect. When the hand screw 324 is loosened, the direction of the universal extension rod 33 can be adjusted arbitrarily to control the overall posture of the adjustment arm 3 and the position of the clamping assembly 4.

[0041] Working principle: The utility model can be connected to the operating table by using the mounting seat 1, the height adjustment rod 2 and the adjustment arm 3 can be used to adjust the overall posture and control the position of the clamping component 4, and the clamping component 4 can be used to fix the medical device, so that the utility model can be used to replace the assistant to complete the purpose of holding the medical device, avoiding the assistant's muscle fatigue, posture discomfort and other situations that affect the progress of the operation.
