Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a retractor for thoracic and abdominal aortic replacement. Background Technology

[0002] When performing thoracic and abdominal surgery on a patient, it is necessary to pull on the thoracic and abdominal wounds to fully expose a suitable surgical field so that the doctor can perform the surgery.

[0003] Traditionally, traction of chest and abdominal wounds is performed manually. Manual traction requires multiple people to perform it simultaneously, which is labor-intensive and unstable during the operation, thus adversely affecting the surgery.

[0004] To address the shortcomings of traditional manual traction, retractors are currently used to pull the skin of the chest and abdomen. Existing retractors mainly consist of multiple hooks and a bracket for positioning the hooks. The bracket is a single, non-removable unit, resulting in a bulky retractor that requires large sterilization equipment for disinfection. This leads to high costs and a large footprint. Furthermore, the traction angle of the current positioning hooks is not adjustable, requiring different models of retractors for patients of different body types. Summary of the Invention

[0005] The purpose of this invention is to provide a retractor for thoracic and abdominal aortic replacement, thereby solving the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0031] like Figure 1-3As shown, a retractor for thoracic and abdominal aortic replacement includes a clamping assembly 1 connected to an operating table. The clamping assembly includes a vertical rod 101 and an upper clamping member 102 connected to the bottom of the vertical rod 101. The upper clamping member 102 has a clamping groove 106. The top inner wall of the vertical rod 101 has a threaded groove. The bottom of the threaded groove and the top of the upper clamping member 102 have a through hole 103. The through hole 103 communicates with the clamping groove 106. A knob 104 is threadedly connected to the threaded groove. The bottom of the knob 104 is connected to a central rod 105. The bottom of the central rod 105 passes through the through hole 103 and is placed in the clamping groove 106. The bottom of the central rod 105 is rotatably connected to one end of a lower clamping member 107. The middle position of the lower clamping member 107 is rotatably connected to the clamping groove 106 via a rotating shaft. The other end of the lower clamping member 107 cooperates with the upper clamping member 102 to clamp the edge of the operating table. In use, the upper end of the upper clamp 102 is pressed against the edge of the operating table, so that the edge of the operating table is placed in the clamping slot 106. The lower clamp 107 is placed below the edge of the operating table. Then, by rotating the knob 104, the center rod 105 is lowered, which in turn causes the end of the lower clamp 107 connected to the center rod 105 to fall, thereby causing the other end of the lower clamp 107 to rise. Thus, the lower clamp 107, in conjunction with the upper clamp 102, is fixed to the edge of the operating table.

[0032] like Figure 2-3 As shown, the upper half of the snap-fit ​​assembly 1 is connected to a connecting rod 3 via a first locking assembly 2.

[0033] The connecting rod 3 includes a straight rod and a bent rod. The straight end of the bent rod is connected to an insert rod. The insert rod is inserted into a slot opened on one end of the straight rod. A ball retainer is installed on the insert rod. The ball of the ball retainer is locked in a locking hole opened on the slot of the straight rod. The other end of the straight rod is connected to the first locking assembly 2.

[0034] The first locking assembly 2 includes a deformable first magic arm rotating fixing clamp 201 and a second magic arm rotating fixing clamp 202. The first magic arm rotating fixing clamp 201 and the second magic arm rotating fixing clamp 202 are locked by a screw. The end of the screw is connected to a rotating handle. The outer walls of the first magic arm rotating fixing clamp 201 and the second magic arm rotating fixing clamp 202 are provided with ring teeth. The two ring teeth are locked together after the first magic arm rotating fixing clamp 201 and the second magic arm rotating fixing clamp 202 are clamped. The upright 101 is placed inside the second magic arm rotating fixing clamp 202, and the connecting rod 3 is placed inside the first magic arm rotating fixing clamp 201. In use, adjust the position of the second magic arm rotating fixing clamp 202 on the upright 101, adjust the clamping position of the connecting rod 3, then select the angle between the first magic arm rotating fixing clamp 201 and the second magic arm rotating fixing clamp 202, and rotate the rotating handle to make the screws on the first magic arm rotating fixing clamp 201 and the second magic arm rotating fixing clamp 202 rotate, so that the first magic arm rotating fixing clamp 201 and the second magic arm rotating fixing clamp 202 clamp the connecting rod 3 and the upright 101 respectively, and at the same time, the angle of the connecting rod 3 is fixed by the two ring teeth.

[0035] like Figure 1-2 As shown, the other end of the connecting rod 3 is connected to two symmetrically arranged universal balls 5 through the second locking assembly 4. The second locking assembly 4 includes a rotating pressing locking clamp 401. The screw of the rotating pressing locking clamp 401 passes through the rotating pressing locking clamp 401 and then through the connecting plate 402 at the end of the connecting rod 3. The bottom of the screw is connected to a second top plate, which abuts against the bottom surface of the connecting plate 402. Both the top surface of the connecting plate 402 and the bottom surface of the rotating pressing locking clamp 401 are provided with ring teeth. The two ring teeth can be locked together. The universal balls 5 are engaged with the rotating pressing locking clamp 401. In use, by rotating the handle on the rotary pressing locking clamp 401, the elliptical block on the handle presses against the top surface of the rotary pressing locking clamp 401, causing the screw inside the rotary pressing locking clamp 401 to rise, thereby clamping one end of the opening of the rotary pressing locking clamp 401, which in turn can clamp and fix the two universal balls 5. At the same time, the bottom of the screw drives the connecting plate 402 to press against the bottom of the rotary pressing locking clamp 401 through the second top plate, and fixes the angle of the connecting plate 402 through the two ring teeth, and fixes the connecting plate 402 to the bottom of the rotary pressing locking clamp 401.

[0036] like Figure 1-2As shown, a connecting rod 6 is connected to the omnidirectional ball 5. The connecting rod 6 includes a first bent section 601, several intermediate straight sections 602, and a second bent section 603. The first bent section 601, several intermediate straight sections 602, and the second bent section 603 are connected by ball springs. The number of intermediate straight sections 602 is selected according to the patient's physique. The other end of the first bent section 601 is fixedly connected to the omnidirectional ball 5.

[0037] like Figure 1-2 As shown, several first traction components 8 and second traction components 9 are installed on the connecting rod 6 via a third locking assembly 7.

[0038] like Figure 4-5 As shown, the third locking assembly 7 includes a third magic arm rotating fixing clamp 701 and a linkage snap-fit ​​assembly. The first traction assembly 8 and the second traction assembly 9 are snapped onto the third magic arm rotating fixing clamp 701. The linkage snap-fit ​​assembly includes an L-shaped fixing member 702 and a deformation snap-fit ​​member 704 connected to the inner side of the L-shaped fixing member 702 via a connecting block 703. One end of the deformation snap-fit ​​member 704 has an arc-shaped bottom surface, and the other end has a flat surface. A through hole is provided at one end of the flat surface of the deformation snap-fit ​​member 704. The bottom of the screw of the third magic arm rotating fixing clamp 701 passes through the third magic arm rotating fixing clamp 701 and the through hole in sequence and is connected to a third top plate. The upper and lower third top plates can drive the deformation snap-fit ​​member 704 to deform. The third top plate rests on the bottom surface of the deformation snap-fit ​​member 704. The connecting rod 6 is snapped into the arc-shaped surface of the deformation snap-fit ​​member 704. In use, the body of connecting rod 2 6 is placed in the groove formed in the arc-shaped surface of the deformation clamp 704. Then, the first traction component 8 and the second traction component 9 are clamped onto the third magic arm rotating clamp 701. Then, by rotating the handle on the third magic arm rotating clamp 701, one end of the clamping tube at the end of the third magic arm rotating clamp 701 is brought closer to each other, thereby clamping the rods on the first traction component 8 and the second traction component 9. At the same time, due to the rotation of the handle, the bottom of the screw on the third magic arm rotating clamp 701 will drive the flat end of the deformation clamp 704 to move closer to the arc-shaped end, thereby clamping the connecting rod 3 801 and the connecting rod 4 901 on the first traction component 8 and the second traction component 9.

[0039] like Figure 6-7 As shown, the first traction assembly 8 includes a connecting rod 801 and an angle adjustment structure connected to one end of the connecting rod 801. One end of the connecting rod 801 is snapped onto the third magic arm rotating fixing clamp 701. The other end of the angle adjustment structure is connected to a disc 803 by a butterfly bolt 802. Several arc-shaped hooks 804 are connected to the disc 803.

[0040] The angle adjustment structure includes a mounting bracket 805 connected to the end of the connecting rod 801. A rotating frame 806 is hinged to the end of the mounting bracket 805 away from the connecting rod 801. A wing bolt 802 is connected to the rotating frame 806. A central shaft 807 is provided on the rotating frame 806. A connecting ring 808 is rotatably connected to the central shaft 807. An adjusting screw 809 is connected to the connecting ring 808. The body of the adjusting screw 809 is threadedly connected to the mounting bracket 805. When it is necessary to adjust the angle of the arc hook 804, the horizontal angle of the arc hook 804 can be adjusted by loosening the wing bolt 802. By rotating the rotating block on the body of the adjusting screw 809, the end of the adjusting screw 809 rotates against the central shaft 807, thereby rotating the rotating frame 806 and adjusting the vertical angle of the arc hook 804.

[0041] like Figure 8-10 As shown, the second traction component 9 includes a connecting rod 901. One end of the connecting rod 901 is snapped onto the third magic arm rotating fixing clamp 701. An arc-shaped pull plate 902 is connected to the other end of the connecting rod 901. An anti-slip pad 903 is provided on the inner side of the arc-shaped pull plate 902.

[0042] The operation process of this invention is as follows:

[0043] When using it, select the installation position of the retractor and fix it to the operating table through the snap-fit ​​component 1. Then, adjust the snap-fit ​​position and snap-fit ​​angle of the connecting rod 1 3 according to the patient's physique. After adjustment, tighten it through the first locking component. Then, select an appropriate number of intermediate straight sections 602 according to the patient's physique and splice the connecting rod 2 6 on them. Then, adjust the angle and direction between the two connecting rods 2 6 by moving the connecting rod 2 6. Then, tighten it through the second locking component. Then, install an appropriate number of the first traction component 8 and the second traction component 9 through the third locking component 7. After the thoracotomy, pull the tissue through the arc-shaped pull hook 804 and the arc-shaped pull plate 902.
