Description

Technical Field

[0001] This invention belongs to the field of medical technology, and in particular relates to a retractor for urological surgery. Background Technology

[0002] In urological surgeries involving the scrotum and testicles, doctors make precise incisions in the scrotum. Then, using a retractor, they carefully and slowly pull the incision open. During this process, the doctor focuses on meticulous manipulation of the subcutaneous tissue. The retractor plays a crucial role here, steadily opening the scrotal incision and creating a wide and clear surgical field for the doctor, enabling them to perform various surgical procedures on the testicles accurately and smoothly.

[0003] When it is necessary to use a retractor to open a patient's scrotal incision, the doctor usually needs to hold the retractor to open the incision before performing surgery inside the scrotal incision. However, the operation time is usually long, and after holding the retractor for a long time, the doctor's hand is prone to shaking, which may cause the scrotal incision to be pulled, affecting the patient's operation. In addition, when opening the incision, the retractor may obstruct the scrotal incision, affecting the doctor's field of vision and operating space. At the same time, when making an incision in the scrotum, the incision is usually made according to the location of the operation, and the size and angle of the incision will vary. When using a retractor to open the scrotal incision, it is necessary to change the corresponding retractor according to the size and angle of the incision, which is inefficient and greatly reduces the efficiency and reliability of opening the scrotal incision.

[0004] Therefore, we propose a retractor for urological surgery to solve the above problems. Summary of the Invention

Furthermore, the positions of multiple fixation blocks can be adjusted according to the shape of the scrotal incision, ensuring that the shape formed by the multiple fixation blocks matches the shape of the scrotal incision. This facilitates the fixation of the skin on both sides of the scrotal incision for retraction, eliminating the need for the doctor to change the retraction device based on the size and angle of the incision. This significantly improves the efficiency and reliability of scrotal incision retraction. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] The following electrical components are all electrically connected to the external PLC controller.

[0026] Reference Figures 1-7 A retractor for urological surgery includes a bed frame 1. Support legs 2 are fixedly connected to the four corners of the bottom of the bed frame 1. Two support rods 3 are fixedly connected to the bottom side wall of the bed frame 1. One end of the two support rods 3 is fixedly connected to the same fixing plate 4. A clearance groove 5 is provided on the top side wall of the bed frame 1. A position adjustment component 6 for adjusting the retractor according to the patient's height and the position of the scrotal incision is fixedly connected to the inner wall of the fixing plate 4. A fixing component adjustment component 7 is provided on one side of the position adjustment component 6 for adjusting the position of the internal fixing component of the retractor according to the shape of the scrotal incision. A scrotal side clamping component 8 is provided on one side of the fixing component adjustment component 7 for clamping the two sides of the scrotal incision.

[0027] In this embodiment, the position adjustment component 6 includes a first slide rail 61 fixedly connected to the inner wall of the fixed plate 4, a first slide plate 62 slidably connected to the top side wall of the first slide rail 61, a first electric telescopic rod 63 fixedly connected to the top side wall of the first slide plate 62, a connecting plate 64 fixedly connected to the telescopic end of the first electric telescopic rod 63, a connecting block 65 rotatably connected to the side wall of the connecting plate 64, a first motor 66 fixedly connected to the side wall of the connecting plate 64, and the output end of the first motor 66 passing through the side wall of the connecting plate 64 and fixedly connected to the side wall of the connecting block 65.

[0028] The inner wall of the connecting block 65 is fixedly connected to a second slide rail 67. The side wall of the second slide rail 67 is slidably connected to two second slide plates 68. The inner wall of the second slide plates 68 is fixedly connected to a second motor 69. The output end of the second motor 69 is fixedly connected to a first clamping plate 610. The inner wall of the first clamping plate 610 is rotatably connected to a first round rod 611.

[0029] A third motor 612 is fixedly connected to the side wall of the first card plate 610. The output end of the third motor 612 passes through the side wall of the first card plate 610 and is fixedly connected to one end of the first round rod 611. A second electric telescopic rod 613 is fixedly connected to the rod wall of the first round rod 611.

[0030] Specifically, when it is necessary to retract the scrotal incision, the position and angle of the fixing block 86 can be adjusted according to the location and angle of the scrotal incision. This allows the fixing block 86 to be used to fix both sides of the scrotal incision, thereby retracting the scrotal incision. This avoids the need for the doctor to use a retractor to retract the incision. At the same time, the fixing block 86 is tilted towards both sides of the scrotal incision to retract it, ensuring that the frontal position of the scrotal incision is not obstructed, thus avoiding affecting the doctor's field of vision and operating space.

[0031] In this embodiment, the fixing member adjustment assembly 7 includes a mounting block 71 fixedly connected to the telescopic end of the second electric telescopic rod 613. The inner wall of the mounting block 71 is fixedly connected to a third slide rail 72. The side walls of the third slide rail 72 are slidably connected to a plurality of third slide plates 73. The side walls of the plurality of third slide plates 73 are fixedly connected to a movable plate 74. The inner wall of the movable plate 74 is fixedly connected to a fourth slide rail 75. The side walls of the fourth slide rail 75 are slidably connected to a fourth slide plate 76. The side walls of the fourth slide plate 76 are fixedly connected to a second locking plate 77.

[0032] The inner wall of the second clamping plate 77 is rotatably connected to a second round rod 78. The side wall of the second clamping plate 77 is fixedly connected to a fourth motor 79. The output end of the fourth motor 79 passes through the side wall of the second clamping plate 77 and is fixedly connected to one end of the second round rod 78. The rod wall of the second round rod 78 is fixedly connected to a third electric telescopic rod 710. The telescopic end of the third electric telescopic rod 710 is fixedly connected to a clamping plate 711.

[0033] The scrotum clamping assembly 8 includes a fifth slide rail 81 fixedly connected to the inner wall of the clamping plate 711. Two fifth slide plates 82 are slidably connected to the side walls of the fifth slide rail 81. Connecting rods 83 are rotatably connected to the side walls of the fifth slide plates 82. The two connecting rods 83 are rotatably connected to each other at their intersection. A locking block 84 is fixedly connected to one end of each connecting rod 83.

[0034] The side wall of the locking block 84 has a first groove 85, and a fixing block 86 is movably connected to the inner wall of the first groove 85. The side wall of the first groove 85 has a first opening 87, and a baffle 88 is abutted to the inner wall of the first opening 87. The side wall of the baffle 88 and the side wall of the locking block 84 are fixedly connected by the same spring 89. The bottom side wall of the baffle 88 abuts against the top side wall of the fixing block 86. After each operation, the doctor pulls the baffle 88 to move it away from the locking block 84, overcoming the elastic force of the spring 89, without obstructing the fixing block 86. The doctor then removes the fixing block 86 from the first groove 85. After disinfecting the fixing block 86 after use, the fixing block 86 is returned to its original position. The baffle 88 is then released, and the baffle 88 continues to limit the fixing block 86, facilitating quick disassembly of the fixing block 86 and enabling the doctor to quickly disinfect the fixing block 86, thus improving work efficiency.

[0035] Specifically, the position of multiple fixing blocks 86 can be adjusted according to the shape of the scrotal incision, so that the shape formed by the multiple fixing blocks 86 is the same as the shape of the scrotal incision. This makes it easier to use the fixing blocks 86 to fix the skin on both sides of the scrotal incision to pull the scrotal incision open. This avoids the need for doctors to change the corresponding pulling device according to the size and angle of the incision, and greatly improves the efficiency and reliability of pulling the scrotal incision open.

[0036] The operating principle of the present invention is now described as follows:

[0037] In this invention, when surgery is required on the testicles within the scrotum, the patient lies on the bed frame 1 with their feet facing the side of the relief groove 5. Then, when it is necessary to retract the scrotal incision, the first electric telescopic rod 63 is activated, causing the connecting plate 64 to move upwards, moving the connecting block 65 from the relief groove 5 to the upper end of the bed frame 1. Next, the first motor 66 is activated, causing the connecting block 65 to rotate. After the inclination angle of the second slide rail 67 is the same as the inclination angle at the scrotal incision, the first motor 66 is deactivated. Then, the first slide rail 61 is activated, causing the first sliding plate 62 to move, bringing the fixing block 86 closer to the scrotal incision. Finally, the third motor 612 is activated, causing the first round rod 611 to rotate. During the operation, the second electric telescopic rod 613 will rotate. After multiple fixed blocks 86 face the corresponding scrotal incision, the third motor 612 will be turned off. Then, the third slide rail 72 and the fourth slide rail 75 will be activated, moving the corresponding third slide plate 73 and the fourth slide plate 76 to move the corresponding fixed blocks 86 to the designated fixed position at the scrotal incision, and making the shape formed by the multiple fixed blocks 86 match the shape of the scrotal incision. Then, the second motor 69 will be activated, moving the fixed blocks 86 closer to the scrotal incision. Then, the fourth motor 79 will be activated, rotating the second round rod 78. During the rotation of the second round rod 78, the clamping plate 711 will rotate the corresponding two fixed blocks 86. After each set of fixed blocks 86 faces the opposite side, the third motor 612 will be turned off. After moving the fourth motor 79 to one side of the scrotal incision, the third electric telescopic rod 710 is activated, moving the fixing block 86 towards the scrotal incision. Just as the fixing block 86 is about to reach the scrotal incision, the third electric telescopic rod 710 is deactivated. Then, the fifth slide rail 81 is activated, moving the two corresponding fifth sliding plates 82 towards the center. At this time, one end of the two connecting rods 83 follows, causing the fixing block 86 to move forward a short distance while clamping the skin on one side of the scrotal incision. This completes the clamping of the skin on both sides of the scrotal incision. Next, the second slide rail 67 is activated, moving the two second sliding plates 68 in opposite directions, thus moving the corresponding fixing block 86. The fixing block 86 then secures the scrotal incision. The scrotum is opened on both sides, facilitating internal surgery at the scrotal incision site. Simultaneously, because the multiple fixation blocks 86 are angled towards both sides of the scrotal incision, the frontal space of the scrotal incision is unobstructed, providing the surgeon with a wider field of vision and enabling stable surgery. When retraction of the scrotal incision is needed, the position and angle of the fixation blocks 86 can be adjusted according to the location and angle of the scrotal incision. This allows for the use of the fixation blocks 86 to fix both sides of the scrotal incision, thereby retracting the scrotal incision without requiring the surgeon to manually retract it. Furthermore, the angled fixation blocks 86 towards both sides of the scrotal incision ensure an unobstructed frontal view, avoiding any impact on the surgeon's field of vision and operating space.Furthermore, the positions of multiple fixing blocks 86 can be adjusted according to the shape of the scrotal incision, ensuring that the shape formed by the fixing blocks 86 matches the shape of the scrotal incision. This facilitates the use of the fixing blocks 86 to fix the skin on both sides of the scrotal incision and to retract it, eliminating the need for doctors to change the retraction device based on the size and angle of the incision. This significantly improves the efficiency and reliability of retraction when retracting the scrotal incision.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
