Description

Technical Field

[0001] The utility model relates to the field of anorectal surgery, in particular to a traction device for anorectal surgery. Background Art

[0002] During anorectal surgery, patients usually need to adopt a specific posture to facilitate the doctor's surgical operation. During anal fistula repair surgery, patients usually need to undergo local anesthesia or general anesthesia. During local anesthesia, patients are required to maintain a knee-chest position to facilitate the operation by medical staff.

[0003] When the patient maintains the knee-chest position for a long time, the anal fistula repair operation requires the patient's legs to be opened. During the operation under manual local anesthesia, the patient's discomfort may cause the legs to be clamped together, making it impossible to quickly pull the patient's legs, resulting in a waste of time during the operation. Utility Model Content

[0004] The main purpose of the utility model is to provide a traction device for anorectal surgery, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A traction device for anorectal surgery comprises a mounting plate, a traction structure is arranged in the middle of the upper end of the mounting plate, the traction structure comprises a vertical rod, and a control box is installed on the upper end of the vertical rod, a bidirectional screw rod is arranged inside the control box, and two groups of sliders are sleeved on the outer wall of the bidirectional screw rod, a connecting plate is installed on one side of the two groups of sliders, and a traction plate is installed at the rear end of the connecting plate.

[0007] As a further solution of the utility model, a stabilizing oblique rod is installed at the front end and the rear end of the control box, and the lower end of the stabilizing oblique rod is fixedly connected to the mounting plate.

[0008] As a further solution of the utility model, two groups of guide rods are installed on the upper end of the mounting plate, and the outer wall of the guide rod is provided with a belly support plate, an adjustment structure is installed on one side of the guide rod, the adjustment structure includes a screw, and the belly support plate is threadedly installed on the outer wall of the screw.

[0009] As a further solution of the utility model, an arc-shaped cushion is installed on the upper end of the abdomen support plate, and a handle is fixedly connected to the upper end of the screw.

[0010] As a further solution of the utility model, an assembly plate is provided on one side of the control box, and a liquid receiving box is installed on the upper end of the assembly plate.

[0011] As a further solution of the utility model, a T-shaped plate is installed at the lower end of the liquid receiving box, and a T-shaped groove is opened at the upper end of the assembly plate.

[0012] As a further solution of the utility model, a pull rod is installed on one side of the liquid receiving box, and the pull rod is in a C shape.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting up the traction structure, when performing anal fistula repair surgery on a patient, when the patient's legs are clamped due to pain, the medical staff can quickly pull the patient's legs to both sides to ensure that the position of the anus is exposed more clearly;

[0015] By setting up the adjustment structure, when the patient lies down in the knee-chest position, the height of the abdominal support plate can be adjusted according to the height, thereby ensuring that the patient's abdomen has a support point, avoiding the situation where the knees are squeezed and painful due to support only with the knees, and ensuring the success of the operation.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4As shown, a traction device for anorectal surgery includes a mounting plate 1, a traction structure 2 is arranged in the middle of the upper end of the mounting plate 1, the traction structure 2 includes a vertical rod 3, and a control box 4 is installed on the upper end of the vertical rod 3, a bidirectional screw rod 5 is arranged inside the control box 4, and two groups of sliders 6 are sleeved on the outer wall of the two groups of sliders 6, a connecting plate 7 is installed on one side of the two groups of sliders 6, and a traction plate 8 is installed at the rear end of the connecting plate 7.

[0023] In this embodiment, a stabilizing diagonal rod 9 is installed at the front and rear ends of the control box 4 , and the lower end of the stabilizing diagonal rod 9 is fixedly connected to the mounting plate 1 .

[0024] The stabilizing diagonal rod 9 is used to ensure that the control box 4 is placed stably.

[0025] In this embodiment, two groups of guide rods 12 are installed at the upper end of the mounting plate 1, and the outer wall of the guide rod 12 is provided with a belly support plate 13. An adjustment structure 10 is installed on one side of the guide rod 12. The adjustment structure 10 includes a screw 11, and the belly support plate 13 is threadedly installed on the outer wall of the screw 11.

[0026] The guide rod 12 is used to ensure that the abdomen support plate 13 can be stably raised and lowered, and the screw rod 11 is used to adjust the position of the abdomen support plate 13 .

[0027] In this embodiment, an arc-shaped cushion is installed on the upper end of the abdomen support plate 13 , and a handle 14 is fixedly connected to the upper end of the screw rod 11 .

[0028] The arc-shaped cushion is used to better contact the patient's abdomen, and the handle 14 is used to facilitate the rotation of the screw 11.

[0029] In this embodiment, an assembly plate 15 is disposed on one side of the control box 4 , and a liquid receiving box 16 is installed on the upper end of the assembly plate 15 .

[0030] The assembly plate 15 is used to connect to a liquid collecting box 16, and the liquid collecting box 16 is used to collect liquid left during surgery.

[0031] In this embodiment, a T-shaped plate 17 is installed at the lower end of the liquid receiving box 16 , and a T-shaped groove 18 is opened at the upper end of the assembly plate 15 .

[0032] The T-shaped plate 17 is used to match with the T-shaped slot 18 .

[0033] In this embodiment, a pull rod is installed on one side of the liquid receiving box 16, and the pull rod is in a C shape.

[0034] The pull rod facilitates the later removal of the docking liquid box 16 by pulling.

[0035] It should be noted that the utility model is a traction device for anorectal surgery. When in use, the patient lies on the upper end of the abdominal support plate 13 in a knee-chest position, so that the two legs are located on both sides of the two sets of traction plates 8, and an anal fistula repair surgery is performed on the patient. When the patient involuntarily clamps his legs due to pain, the bidirectional screw rod 5 is rotated, so that the slider 6 moves to the front and rear ends, thereby driving the traction plates 8 to move relative to each other, supporting and opening the patient's legs, and facilitating clear exposure of the anus position;

[0036] After the patient's legs are extended, the handle 14 is rotated, so that the handle 14 drives the screw 11 to rotate, so that the abdomen support plate 13 moves downward, so that the abdomen support plate 13 is in higher contact with the patient's abdomen, thereby reducing the force on the knee area.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
