Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides a long seat for minimally invasive surgical tissue clamps that is easy to telescope and move: it includes a placement base 1 and a moving mechanism 3, the bottom surface of the placement base 1 is slidably connected to a clamp base 2, the inner surface of the placement base 1 is provided with the moving mechanism 3, the outer surface of the placement base 1 is provided with a telescopic mechanism 4, and the inner surface of the placement base 1 is fixedly connected to a fixing clamp 5.

[0022] Furthermore, the moving mechanism 3 includes a threaded shaft 301, a driven worm gear 302, a support shell 303, a support sleeve 304, a driving worm 305 and a knob 306. The inner surface of the placement base 1 is threadedly connected with the threaded shaft 301, one end of the threaded shaft 301 is fixedly connected with the driven worm gear 302, the outer surface of the clamp base 2 is fixedly connected with the support shell 303, the outer surface of the clamp base 2 is fixedly connected with the support sleeve 304, the inner surface of the support sleeve 304 is rotatably connected with the driving worm 305, and the two ends of the driving worm 305 are fixedly connected with the knob 306. The rod 305 and the knob 306 are arranged such that, during use, the knob 306 is turned to drive the active worm 305 to rotate, the active worm 305 is supported by the support sleeve 304 and meshes with the driven worm gear 302, the driven worm gear 302 is supported by the support shell 303 and drives the threaded shaft 301 to rotate during the rotation, the threaded shaft 301 is threadedly connected to the placement base 1, and the rotation is converted into linear movement through the threaded transmission, driving the placement base 1 to move to achieve the movement effect of the tissue clamp, and because the driven worm gear 302 and the active worm 305 are worm and worm gear transmission, they have a large transmission ratio and can make very fine movements for medical use, and at the same time have self-locking properties to prevent the placement base 1 from moving on its own.

[0023] Furthermore, the threaded shaft 301 penetrates the placement base 1, and the driven worm gear 302 is slidably connected to the inner surface of the support shell 303. The driven worm gear 302 is supported by the support shell 303 and drives the threaded shaft 301 to rotate during the rotation. The rotation is converted into linear movement through the thread transmission, driving the placement base 1 to move to achieve the movement effect of the tissue clamp.

[0024] Furthermore, the number of the supporting sleeves 304 is two and they are symmetrically distributed, the driven worm wheel 302 is meshed with the driving worm 305, the rotating knob 306 drives the driving worm 305 to rotate, and the driving worm 305 is supported by the supporting sleeves 304 and meshed with the driven worm wheel 302 to drive it to rotate.

[0025] Furthermore, the telescopic mechanism 4 includes a sliding rod 401, a support frame 402, a rotating block 403, a contact rod 404, a limit block 405 and a mounting groove 406. The outer surface of the placement base 1 is slidably connected with the sliding rod 401, one end of the sliding rod 401 is fixedly connected with the support frame 402, the outer surface of the sliding rod 401 is rotatably connected with the rotating block 403, the outer surface of the rotating block 403 is fixedly connected with the contact rod 404, the inner surface of the placement base 1 is snap-connected with the limit block 405, and the inner surface of the placement base 1 is provided with a mounting groove 406. The setting of the limit block 405 and the installation groove 406 allows the sliding rod 401 to be moved out of the placement base 1 to be extended and retracted during use, thereby adjusting the position of the support frame 402 to achieve the effect of placing the support range of the base 1. During the process of the sliding rod 401 moving outward, the contact rod 404 can rotate around the rotating block 403, and when it contacts the limit block 405, it will rotate and slide over, and when it moves inward, it will be stuck in the limit block 405 and cannot rotate, thereby preventing the support frame 402 from retreating after support and causing unstable support. The installation groove 406 can be inserted and installed with the limit block 405, and the limit block 405 is set at a commonly used support position.

[0026] Furthermore, both sides of the sliding rod 401 are slidably connected to the inner surface of the placement base 1 , and the limit blocks 405 are equidistantly distributed on the inner surface of the placement base 1 .

[0027] Furthermore, the contact rod 404 is slidably connected to the outer surface of the limiting block 405 , and the limiting block 405 is snap-fitted to the inner surface of the mounting groove 406 .

[0028] Working principle: A long seat for minimally invasive surgical tissue clamp that is easy to telescopically move. Turning the knob 306 drives the active worm 305 to rotate. The active worm 305 is supported by the support sleeve 304 and meshes with the driven worm wheel 302. The driven worm wheel 302 is supported by the support shell 303 and drives the threaded shaft 301 to rotate during the rotation. The threaded shaft 301 is threadedly connected with the placement base 1. The rotation is converted into linear movement through thread transmission, which drives the placement base 1 to move to achieve the movement effect of the tissue clamp. In addition, since the driven worm wheel 302 and the active worm 305 are worm and worm gear transmissions, they have a large transmission ratio and can make very fine movements for medical use. At the same time, they have self-locking properties to prevent the placement base 1 from being locked. The sliding rod 401 can move on its own and be moved out of the placement base 1 to be extended and retracted, thereby adjusting the position of the support frame 402 to achieve the effect of placing the support range of the base 1. During the process of the sliding rod 401 moving outward, the contact rod 404 can rotate around the rotating block 403, and when it contacts the limit block 405, it will rotate and slide over, and when it moves inward, it will be stuck in the limit block 405 and cannot rotate, thereby preventing the support frame 402 from retreating after support and causing unstable support. The mounting groove 406 can be inserted and installed with the limit block 405, and the limit block 405 is set at a commonly used support position, thus completing a long seat for minimally invasive surgical tissue clamps that is easy to telescope and move.
