Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a semi-annular surgical retractor device. Background Art

[0002] Surgical retractors are mainly used for cutting, suturing and tissue separation during surgery. During surgery, it is often necessary to use retractors to pull apart skin tissue, so a semi-circular surgical retractor device came into being.

[0003] Although current technology has many advantages, the disadvantage of current technology is that traditional surgical retractors need to be manually held when in use, and the traction action should be gentle to avoid excessive force. Since most operations take too long, the doctor's physical strength is gradually consumed, resulting in incomplete exposure of the surgical field and inability to operate accurately. At the same time, the existing surgical retractor device is ring-shaped, but since the patient's surgical incision is very small, and the doctor also needs to perform surgery in this very small surgical incision, such a ring-shaped retractor device will occupy most of the surgical operating space, which is not conducive to the operation of the operation, affects the doctor's surgical efficiency, increases the operation time, and is not conducive to the treatment of the patient.

[0023] See also Figure 1-4 The utility model provides a technical solution: a semi-annular surgical retractor device, comprising: a retractor bracket 1, both ends of the retractor bracket 1 are fixedly connected to a limited block 2, and also comprising: a plurality of connectors 3, the outer surfaces of the plurality of connectors 3 are provided with a slide groove 4, the sides of the plurality of connectors 3 close to the plurality of slide grooves 4 are provided with a notch 23, the sides of the plurality of connectors 3 away from the plurality of slide grooves 4 are provided with a fixed groove 5, the inner surfaces of the plurality of slide grooves 4 are movably embedded with a tooth plate 6, the outer surfaces of the plurality of tooth plates 6 are fixedly connected with a retractor block 7, the bottom outer surfaces of the plurality of tooth plates 6 are fixedly connected with a connecting plate 8, the bottom outer surfaces of the plurality of connecting plates 8 are fixedly connected with a fixing plate 9, the outer surfaces of the plurality of tooth plates 6 are meshedly connected with a gear 10, and the sides of the plurality of tooth plates 6 away from the plurality of gears 10 are meshedly connected with a gear 2 11, so that the position and angle of the plurality of retractor blocks 7 can be adjusted by rotating the plurality of butterfly bolts 16, avoiding hand-holding of the retractor blocks 7, reducing the labor intensity of the doctor, and keeping the surgical port from being blocked, thereby improving the accuracy of the doctor's surgery.

[0024] like Figure 1-4 As shown, a moving block 17 is movably sleeved on one side of the hook bracket 1 close to the two limit blocks 2, and butterfly bolts 18 are movably sleeved on the top outer surfaces of the two moving blocks 17, and support rods 19 are fixedly connected to the outer surfaces of the two support rods 19, and fixed plates 20 are fixedly connected to the bottom outer surfaces of the two supporting plates 19, and fixed blocks 21 are fixedly connected to the bottom outer surfaces of the two fixed plates 20. In this way, since the hook bracket 1 is semi-annular and the positions of the two moving blocks 17 on the hook bracket 1 can be adjusted as needed to meet the needs of the operation, the operable space for the operation is greatly provided, the implementation of the operation is convenient, the operation efficiency of the doctor is improved, the operation time is saved, and precious time is gained for the patient.

[0025] like Figure 1-4As shown, the inner surfaces of the multiple gears 11 are movably sleeved with a fixing rod 26, the inner surfaces of the multiple gears 10 are fixedly installed with a rotating shaft 12, the top outer surfaces of the multiple rotating shafts 12 are fixedly installed with a rotating block 13, the top outer surfaces of the multiple rotating blocks 13 are fixedly connected with a handle 14, and the multiple connectors 3 are provided with a working groove 15 on one side close to the multiple gears 10 and gear 2 11. The handle 14 can provide a power source for the rotation of the rotating block 13, so that the rotating block 13 can drive the rotating shaft 12.

[0026] like Figure 1-4 As shown, multiple connecting plates 8 are movably embedded in the inner surfaces of multiple slots 23, and multiple fixing plates 9 are movably embedded in the inner surfaces of multiple fixing grooves 5. Multiple connecting plates 8 can prevent the displacement of multiple tooth plates 6, so that the doctor can always clearly see the surgical conditions of the patient's surgical incision.

[0027] like Figure 1-4 As shown, butterfly bolts 3 25 are movably embedded in the bottom outer surfaces of the two fixing blocks 21, and gaskets 22 are fixedly connected to the top outer surfaces of the two butterfly bolts 3 25.

The shafts 12 can transmit the power of the rotating block 13 to the gear 10 to make the gear 10 rotate.

[0031] Working principle: When using the semi-circular surgical hook device, first determine the number of hook blocks 7 required, clamp the multiple connectors 3 on the hook bracket 1, and manually loosen and tighten the multiple butterfly bolts 16 to separate and fit the multiple gaskets 24 with the hook bracket 1 to adjust the positions and angles of the multiple hook blocks 7. After hooking the multiple hook blocks 7 on the patient's surgical port, rotate the multiple handles 14, the multiple handles 14 drive the multiple rotating blocks 13 to rotate, the multiple rotating blocks 13 drive the multiple rotating shafts 12 to rotate, the multiple rotating shafts 12 drive the multiple gears 10 to rotate on the inner surfaces of the multiple working grooves 15, and the multiple gears 10 drive the multiple tooth plates 6 to move on the inner surfaces of the multiple slide grooves 4. The gears 11 move in a circle with the multiple fixed rods 26 as the center as the multiple tooth plates 6 move, and the multiple tooth plates 6 are limited. The multiple tooth plates 6 simultaneously drive the multiple connecting plates 8 to move on the inner surfaces of the multiple slots 23. The multiple connecting plates 8 can prevent the multiple tooth plates 6 from deviating, so that the doctor can always clearly see the surgical conditions of the patient's surgical port. The multiple connecting plates 8 drive the multiple fixing plates 9 to move on the inner surfaces of the multiple fixing slots 5. The multiple fixing plates 9 can further improve the rigidity of the multiple tooth plates 6 and prevent the multiple tooth plates 6 from tilting downward and affecting the doctor's work. In this way, the positions and angles of the multiple hook blocks 7 can be adjusted by rotating the multiple butterfly bolts 16. Adjustment can avoid holding the retractor block 7 by hand, which reduces the doctor's labor intensity and can keep the surgical port from being blocked, thereby improving the accuracy of the doctor's surgery. When fixing the retractor device, the two fixing blocks 21 are close to the operating table, and then the two butterfly bolts 3 25 are manually rotated to make the gasket 22 fit tightly with the bottom of the operating table, so that the two fixing blocks 21 are fixed, and the fixing of the two fixing blocks 21 fixes the two fixing plates 20, and the fixing of the two fixing plates 20 fixes the two support rods 19, and the fixing of the two support rods 19 fixes the two moving blocks 17, so that the two moving blocks 17 remain horizontal, and then the retractor bracket 1 is moved on the inner surface of the two moving blocks 17. The hook bracket 1 is moved to a position that meets the working needs, and the two butterfly bolts 18 are manually rotated to keep the hook bracket 1 horizontal and fixed in the two moving blocks 17. The two limit blocks 2 can prevent the two moving blocks 17 from being separated from the hook bracket 1, thereby avoiding the two moving blocks 17 from being separated from the hook bracket 1 due to misoperation, thereby affecting the work. In this way, since the hook bracket 1 is semi-annular, the positions of the two moving blocks 17 on the hook bracket 1 can be adjusted as needed to meet the needs of the operation, which greatly provides an operable space for the operation, facilitates the implementation of the operation, improves the doctor's operation efficiency, saves operation time, and gains precious time for the patient.
