[0026] Combine the following Figure 1-Figure 4 The utility model is described in detail.

[0027] Example

[0028] A stone removing forceps comprises two hinged forceps handles 2, the top of the forceps handles 2 is connected to an extension rod 6, the top of the extension rod 6 is fixedly connected to a connecting plate 7, a forceps handle 8 is hinged on the connecting plate 7, a plurality of slots 15 are arranged on the connecting plate 7 along the circumference of the hinge point, a locking rod 13 cooperating with the slot 15 is movably penetrated through the side wall of the forceps handle 8, the locking rod 13 is sleeved with a tension spring 14 located on the outer wall of the forceps handle 8, the two ends of the tension spring 14 are respectively fixedly connected to the forceps handle 8 and the locking rod 13, and the top of the forceps handle 8 is connected to a forceps head 11.

[0029] The clamp handle 8 and the connecting plate 7 can rotate relative to each other. The locking rod 13 is pulled out of the slot 15 and then rotated to adjust the angle of the clamp handle 8. After the locking rod 13 is released, the locking rod 13 is inserted into the slot 15 on the clamp handle 8 under the action of the tension spring 14, thereby locking the clamp handle 8 after the angle is adjusted to prevent the clamp handle 8 and the connecting plate 7 from rotating relative to each other. During the operation, the stone removal operation can be carried out after adjusting the appropriate angle according to the needs, avoiding the preparation work of equipping multiple stone removal forceps.

[0030] An angle scale line 16 is provided on the connecting plate 7, and an indicator line matching the angle scale line 16 is provided on the clamp handle 8. The angle scale line 16 can facilitate the user to quickly adjust to a suitable angle. Specifically, the indicator line on the clamp handle 8 can be aligned with the scale on the angle scale line 16. At the same time, a slot 15 is provided corresponding to the scale on the angle scale line 16, that is, after the indicator line is aligned with one of the scales, the locking rod 13 is also aligned with one of the slots 15.

[0031] The locking rod 13 is arranged on the inner side of the clamp handle 8 to prevent the protruding locking rod 13 from being hooked on other objects or human tissues.

[0032] The inner sides of the two clamp handles 8 are respectively provided with a camera 9 and a fill light 12. The camera 9 can take pictures of the surgical site and transmit real-time image data to an external display screen, which is convenient for the doctor to check the location of the stone. The fill light 12 provides light source for the camera 9 to ensure a clear field of vision.

[0033] A square groove 17 is provided in the extension rod 6 along the length direction, a square rod 4 extending into the square groove 17 is fixedly connected to the top of the forceps handle 2, and a fixing screw 5 abutting against the square rod 4 is threadedly penetrated through the side wall of the extension rod 6. The square rod 4 can move along the length direction in the square groove 17, thereby adjusting the length of the entire lithotomy forceps to meet different surgical requirements; after adjusting the appropriate length, the fixing screw 5 is tightened to fix it.

[0034] The fill light 12 and the camera 9 are connected with a wire 3, and the wire 3 is connected with an external power supply; the wire 3 is led out from the clamp handle 8 and enters the connecting plate 7, then enters the extension rod 6 and the square rod 4, and finally passes through the clamp handle 2. The wire 3 is movably arranged in the clamp handle 8, the connecting plate 7, the extension rod 6, the square rod 4 and the clamp handle 2 to ensure the normal rotation of the clamp handle 8 and the normal extension and retraction of the extension rod 6.

[0035] The square rod 4 is provided with length scale lines 18 along the length direction. The lower end of the extension rod 6 is aligned with the scale on the length scale line 18 to indicate the length of the extension rod 6 extension, and it is convenient to extend the two extension rods 6 to the same length at the same time.

[0036] The fixing screw 5 is arranged on the inner side of the clamp handle 8 to prevent the protruding fixing screw 5 from being hooked on other objects or human tissues.

[0037] A plurality of anti-skid particles 10 are arranged on the inner side of the clamp head 11. The anti-skid particles 10 can increase the friction between the clamp head 11 and the stone, and prevent the stone from falling.

[0038] The lower end of the forceps handle 2 is provided with a finger ring 1. The finger ring 1 is convenient for the doctor to control the opening and closing of the forceps handle 2 using his fingers.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
