Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an endoscope cavity clamping device. Background Technology

[0002] Endoscopic surgery (also known as laparoscopic surgery) is a minimally invasive surgical technique that involves inserting an optical lens and surgical instruments into the body's cavities (such as the abdominal cavity, uterine cavity, and thoracic cavity) through a tiny incision (usually 0.5-1 cm) and completing the diagnostic and treatment procedures with the help of real-time image guidance.

[0003] During endoscopic surgery, surgical instruments are inserted into the patient's body through an incision in the skin. However, most of these instruments are movable and require manual operation by the doctor throughout the procedure. The incision may be closed, and friction between the instruments and the edges of the incision during insertion and removal can damage the incision tissue and cause secondary injury to the patient.

[0004] Therefore, a cavity clamping device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a mirror cavity clamping device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A cavity clamping device includes a connecting frame, a guide tube slidably disposed on the connecting frame, a support ring disposed on the guide tube, two movable rods slidably disposed on the connecting frame, an adjustment mechanism for adjusting the position and distance of the two movable rods disposed on the connecting frame, a set of lifting mechanisms for height adjustment disposed on each of the two movable rods, and a suction cup disposed on each of the two sets of lifting mechanisms.

[0008] Furthermore, the top of the connecting frame is provided with a sliding hole, and the conduit is slidably installed on the inner wall of the sliding hole. A magnetic block one is provided inside the sliding hole, and a magnetic block two is provided on the surface of the conduit. The magnetic block one and the magnetic block two are attracted to each other.

[0009] Furthermore, the adjustment mechanism includes a bidirectional screw, which is rotatably mounted on the connecting frame, and a moving rod is threaded onto the outer wall of the bidirectional screw.

[0010] Furthermore, a bevel gear one is fixedly installed on the outer wall of the bidirectional screw, a limiting shaft is rotatably installed on the connecting frame, a bevel gear two is fixedly installed at the bottom of the limiting shaft, and the bevel gear one meshes with the bevel gear two, and a knob one is fixedly installed at the top of the limiting shaft.

[0011] Furthermore, the lifting mechanism includes a fixed frame, which is fixedly installed on the surface of the movable rod. A one-way screw is rotatably installed on the movable rod and is rotatably disposed inside the fixed frame. A lifting column is threadedly installed on the outer wall of the one-way screw and is slidably installed on the inner wall of the fixed frame. A fixed plate is fixedly installed at the bottom of the lifting column and a suction cup is fixedly installed on the surface of the fixed plate. A knob is fixedly installed at the top of the one-way screw.

[0012] Furthermore, two telescopic columns are fixedly installed on the surface of the movable rod, and the telescopic columns are fixedly installed on the surface of the fixed plate.

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

[0014] This invention, through the design of movable rods, adjustment mechanisms, and lifting mechanisms, allows for the adjustment of two movable rods to move closer or further apart according to the patient's posture while lying on the operating table, adapting them to the patient's body width. Two lifting mechanisms then adjust the height of the two movable rods to match the patient's height. The suction cup is then attracted to the operating table, and a catheter is inserted into the patient's body through an incision on the skin. The support ring contacts the patient's skin to support the incision. Magnetic blocks one and two attract each other, thus fixing the connecting frame and the catheter. Surgical instruments can then be inserted into the body through the catheter, improving the stability of endoscopic surgery. This invention is suitable for patients with various body positions, offering high stability, avoiding secondary injury to the patient, and is simple to operate with strong practicality.

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1-3 As shown, a cavity clamping device includes a connecting frame 1, a guide tube 2 slidably mounted on the connecting frame 1, a support ring 3 mounted on the guide tube 2, a sliding hole at the top of the connecting frame 1, and the guide tube 2 slidably mounted on the inner wall of the sliding hole. A first magnetic block is disposed inside the sliding hole, and a second magnetic block is disposed on the surface of the guide tube 2, with the first and second magnetic blocks attracting each other. Two moving rods 4 are slidably mounted on the connecting frame 1, and an adjustment mechanism 5 is provided on the connecting frame 1 for adjusting the position and distance of the two moving rods 4. Figure 1-3As shown, specifically, the adjusting mechanism 5 includes a bidirectional screw 501, which is rotatably mounted on the connecting frame 1. The moving rod 4 is threaded onto the outer wall of the bidirectional screw 501. A bevel gear 502 is fixedly mounted on the outer wall of the bidirectional screw 501. A limiting shaft 503 is rotatably mounted on the connecting frame 1. A bevel gear 504 is fixedly mounted at the bottom of the limiting shaft 503, and the bevel gear 502 meshes with the bevel gear 504. A knob 505 is fixedly mounted at the top of the limiting shaft 503.

[0026] More specifically, by rotating knob 505, the limiting shaft 503 and bevel gear 504 are driven to rotate synchronously, and bevel gear 504 drives bevel gear 502 to rotate. The bidirectional screw 501 rotates accordingly, which allows the two moving rods 4 to move closer to each other or further away from each other, thereby adjusting the distance between the two moving rods 4.

[0027] Each of the two movable rods 4 is equipped with a lifting mechanism 6 for height adjustment, and each lifting mechanism 6 is equipped with a suction cup 7; for example Figure 1-4 As shown, specifically, the lifting mechanism 6 includes a fixed frame 601, which is fixedly installed on the surface of the moving rod 4. A one-way screw 602 is rotatably installed on the moving rod 4, and the one-way screw 602 is rotatably disposed inside the fixed frame 601. A lifting column 603 is threadedly installed on the outer wall of the one-way screw 602, and the lifting column 603 is slidably installed on the inner wall of the fixed frame 601. A fixed plate 605 is fixedly installed at the bottom of the lifting column 603, and a suction cup 7 is fixedly installed on the surface of the fixed plate 605. A knob 606 is fixedly installed at the top of the one-way screw 602. Two telescopic columns 604 are fixedly installed on the surface of the moving rod 4, and the telescopic columns 604 are fixedly installed on the surface of the fixed plate 605.

[0028] More specifically, by rotating knob 606, the one-way screw 602 is rotated, causing the lifting column 603 to move downward and pushing the fixed plate 605 downward, which in turn causes the two telescopic columns 604 to stretch. The suction cup 7 moves accordingly, and the support height of the moving rod 4 increases accordingly. Conversely, the support height of the moving rod 4 decreases accordingly, thereby adjusting the support height of the moving rod 4.

[0029] In summary, during use, depending on the patient's posture while lying on the operating table, the two moving rods 4 are adjusted by adjusting mechanism 5 to move closer or further apart to match the patient's body width. Then, the height of the two moving rods 4 is adjusted by two sets of lifting mechanisms 6 to match the patient's body height. Then, the suction cup 7 is attracted to the operating table. The catheter 2 is inserted into the body through an incision on the patient's skin. The support ring 3 contacts the patient's skin to support the incision. The magnetic blocks 1 and 2 are attracted to each other, thus fixing the connecting frame 1 and the catheter 2. At this time, surgical instruments can be inserted into the body through the catheter 2, improving the stability of endoscopic surgery. This makes it suitable for patients with various body positions for endoscopic surgery, with high stability, avoiding secondary injury to the patient, simple operation, and strong practicality.
