Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically an adjustable abdominal surgical retractor. Background Technology

[0002] In the field of abdominal surgery, surgical retractors are typically used to fully expose the surgical area to the surgical field of vision, thereby ensuring the smooth progress and success of the surgery.

[0003] During the use of abdominal surgical retractors, the size of the surgical area exposed is adjusted by changing the position of the traction claws. After the traction claws are adjusted, the adjustment handle is rotated to fix the adjustment plate at one end of the traction claw with a screw, thereby fixing the position of the adjusted traction claws. Although the operation of fixing the adjusted traction claws by rotating the screw with the handle is convenient, during abdominal surgery, the handle is easily accidentally rotated due to external forces such as collisions of instruments during surgery. This can cause the screw to shift, resulting in a change in the retraction position and affecting the stability of the surgical field.

[0004] Therefore, there is an urgent need for an adjustable abdominal surgical retractor to solve the above problems. Utility Model Content

[0007] A retaining ring is fixedly connected to the side wall of the threaded rod. The retaining ring is located between the U-shaped sliding plate and the mounting ring. A rubber gasket is provided on the side of the retaining ring closest to the mounting ring.

[0008] The anti-rotation assembly includes an anti-rotation cavity formed on the side wall of the threaded rod. A spline groove is formed on the inner wall of the anti-rotation cavity near the clamping ring. A spline plate is slidably connected to the anti-rotation cavity. The spline plate is matched with the spline groove. An anti-rotation rod is fixedly connected to the side of the spline plate away from the spline groove. The end of the anti-rotation rod away from the spline plate passes through the anti-rotation cavity and is connected to the crank handle. The anti-rotation cavity is provided with a retraction assembly for elastically retracting the spline plate.

[0009] The retraction assembly includes a first spring sleeved on the anti-rotation rod located on the inner side wall of the anti-rotation cavity.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-5 The figure shows an adjustable abdominal surgical retractor, including a mounting ring 101. The mounting ring 101 has multiple first through holes 102 on its side wall. Each first through hole 102 has a second through hole 103 on the side away from the operating table. Each first through hole 102 is slidably connected to a U-shaped sliding plate 104. Each U-shaped sliding plate 104 is slidably connected to a strip plate 105. Each strip plate 105 has a traction claw 106 fixedly connected to one end opposite to the other. The device also includes a first adjustment component disposed on the mounting ring 101 for adjusting the length of the traction claw 106 and a second adjustment component disposed on the mounting ring 101 for adjusting the height of the traction claw 106.

[0023] The first adjustment component includes a threaded hole 201 on the side of the sliding plate 104 away from the operating table. The threaded hole 201 is threadedly connected to a threaded rod 202. A clamping groove 203 is provided on the side of the strip plate 105 near the threaded rod 202. The inner wall of the clamping groove 203 is provided with anti-slip texture. The end of the threaded rod 202 away from the strip plate 105 is connected to a crank 204 through an anti-rotation component.

[0024] It should be noted here that the setting of the first adjustment component is used to adjust the exposure size of the traction claw 106 to the surgical incision in the patient's abdomen.

[0025] Please see Figure 4 The threaded rod 202 in the figure is fixedly connected to a retaining ring 205 on its side wall. The retaining ring 205 is located between the sliding plate 104 and the mounting ring 101. A rubber washer 206 is provided on the side of the retaining ring 205 near the mounting ring 101.

[0026] It should be noted that, by setting the clamping ring 205, when one end of the threaded rod 202 abuts against the side wall of the strip plate 105, the clamping ring 205 will abut against the end face of the mounting ring 101, thereby limiting the position of the loop sliding plate 104. Furthermore, the elastic contraction of the rubber gasket 206 provides a space for the threaded rod 202 to abut against the side wall of the strip plate 105.

[0027] Please see Figure 4 The anti-rotation component shown in the figure includes an anti-rotation cavity 301 opened on the side wall of the threaded rod 202. A spline groove 302 is opened on the inner wall of the anti-rotation cavity 301 near the clamping ring 205. A spline plate 303 is slidably connected to the anti-rotation cavity 301. The spline plate 303 is matched with the spline groove 302. An anti-rotation rod 304 is fixedly connected to the side of the spline plate 303 away from the spline groove 302. The end of the anti-rotation rod 304 away from the spline plate 303 passes through the anti-rotation cavity 301 and is connected to the rocker handle 204. The anti-rotation cavity 301 is provided with a retraction component for elastically retracting the spline plate 303.

[0028] It should be noted that the anti-rotation component is designed to reduce the risk of the threaded rod 202 rotating, thereby ensuring the threaded rod 202 maintains its tightness against the strip plate 105, thus guaranteeing the positional stability of the traction claw 106, reducing the risk of changes in the position of the abdominal surgical incision, and ensuring the stability of the surgical field.

[0029] Please see Figure 4 The retraction assembly shown in the figure includes a first spring 401 sleeved on the anti-rotation rod 304 located on the inner side wall of the anti-rotation cavity 301. One end of the first spring 401 is connected to the spline plate 303, and the other end of the first spring 401 is rotatably connected to the inner wall of the anti-rotation cavity 301 away from the spline groove 302 through the connecting ring 402.

[0030] It should be noted here that after the position of the traction claw 106 is defined, the pressure on the crank handle 204 is released. At this time, under the elastic action of the retraction component, the spline plate 303 separates from the spline groove 302.

[0031] Working principle: During use, the retractor first uses the strong magnetic base 6 to fix the whole device to the operating table. Then, the second adjustment component is used to adjust the height of the mounting ring 101. After the height of the mounting ring 101 is adjusted, the traction claw 106 at one end of the strip plate 105 can be moved to a suitable position by rotating the U-shaped sliding plate 104 on the mounting ring 101.

[0032] After the traction claw 106 is moved to the appropriate position, the sliding of the strip plate 105 on the loop-shaped sliding plate 104 causes one end of the traction claw 106 to be inserted into the surgical incision in the patient's abdomen. The sliding of the strip plate 105 on the loop-shaped sliding plate 104 again moves the traction claw 106, thereby pulling the surgical incision in the patient's abdomen, making the surgical incision larger, and thus fully exposing the surgical site.

[0033] After the traction claw 106 is moved to the appropriate position, the spline plate 303 at one end of the anti-rotation rod 304 can be inserted into the spline groove 302 by pressing the crank handle 204. At this time, the crank handle 204 can be rotated, which in turn drives the threaded rod 202 to rotate. By utilizing the threaded engagement transmission between the threaded rod 202 and the loop sliding plate 104, one end of the threaded rod 202 abuts against the bottom wall of the side wall abutting groove 203 of the strip plate 105, thereby achieving the abutting and limiting of the strip plate 105, and thus limiting the position of the traction claw 106.

[0034] After the position of the traction claw 106 is defined, the pressure on the crank handle 204 can be released. At this time, under the elastic action of the retraction component, the spline plate 303 separates from the spline groove 302, so that the crank handle 204 will not be accidentally touched by surgical instruments during the operation, thus preventing the threaded rod 202 from rotating. This ensures that the threaded rod 202 maintains the stability of the clamping of the strip plate 105, thereby ensuring the positional stability of the traction claw 106, reducing the risk of changes in the position of the abdominal surgical incision, and thus ensuring the stability of the surgical field.

[0035] Example 2

[0036] Please see Figure 5This embodiment further illustrates Example 1. The second adjustment component shown in the figure includes multiple adjustment plates 501 fixedly connected to the side of the mounting ring 101 away from the threaded rod 202. Each adjustment plate 501 has an adjustment frame 502 sleeved on its side wall. Each adjustment frame 502 has a T-shaped insert rod 504 slidably connected to its side wall. Each T-shaped insert rod 504 has a second spring 505 sleeved on its side wall. The two ends of each second spring 505 are respectively connected to the side wall of the adjustment frame 502 and the T-shaped insert rod 504. Each adjustment plate 501 has multiple adjustment holes 503 on its side away from the medical staff. The T-shaped insert rod 504 is matched with each adjustment hole 503.

[0037] It should be noted that: by setting the second adjustment component, the height of the mounting ring 101 from the operating table can be adjusted by the contraction of the adjustment plate 501 within the adjustment frame 502, thereby meeting the surgical needs of different patients. After the height of the adjustment plate 501 is adjusted, the position of the adjustment plate 501 can be limited by inserting the T-shaped rod 504 into the adjustment hole 503 on the side wall of the adjustment plate 501.

[0038] Example 3

[0039] Please see Figure 5 This embodiment is a further explanation of other embodiments. In the figure, each adjustment frame 502 is provided with a strong magnetic base 6 at the end away from the mounting ring 101.

[0040] It should be noted that the strong magnetic base 6 (or vacuum suction cup) is used to connect and limit the adjustment frame 502 to the fixed part of the operating table, thereby fixing the position of the mounting ring 101 and ensuring the positional stability of the whole device during use.
