[0007] Further, two arc segments are symmetrically arranged, one side of the arc segment is fixedly installed with wave-shaped plate, the wave-shaped plate includes a plurality of protrusions and recesses.

[0008] Further, a plurality of anti-skid grooves are formed in one side of the wave-shaped plate, and the plurality of anti-skid grooves on the same wave-shaped plate are arranged at equal intervals.

[0009] Further, a plurality of lightweight holes are formed in the front side of the wave-shaped plate, and the plurality of lightweight holes on the same wave-shaped plate are uniformly distributed.

[0010] Further, one side of the clamp mouth is provided with a notch, and the notches on the two clamp mouths symmetrically arranged on the left and right are centrally symmetrically arranged.

[0011] Further, one side of the straight line segment is provided with an embedding groove, and the two handles are abutted with each other through the two embedding grooves.

[0012] Further, one side of the arc line segment on the left is fixedly installed with an arc-shaped cylinder, and one side of the arc line segment on the right is fixedly installed with an arc-shaped plate which is slidingly installed in the arc-shaped cylinder.

[0013] Further, one side of the arc-shaped cylinder is fixedly installed with an arc-shaped spring, one end of the arc-shaped spring is fixedly installed with a positioning ball, one side of the arc-shaped plate is provided with a hemispherical groove, and the positioning ball is matched with the hemispherical groove.

[0014] The utility model discloses the beneficial effects are:

[0015] 1. The lower half of the handle is arranged as an arc segment, which can exert greater force than the conventional circular ring handle, making the two clamp mouths more stable when combined and clamped on the urethra. The wave-shaped plate and the anti-slip grooves on it improve the stability of the operator's grip and prevent slipping.

[0016] 2. The arc-shaped spring and the arc-shaped ball cooperate to restrict the closure of the two handles, leaving a small opening for grabbing the urethra. When the operator moves the clamp mouth to the designated position, continue to compress the two arc segments, thereby driving the two handles to move closer to each other until the two pairs of clamp mouths are completely closed.

DETAILED DESCRIPTION

[0024] In order to more clearly and completely illustrate the technical scheme of the utility model, the utility model will be further described below in combination with the drawings.

[0025] Please refer to Figures 1-5 The utility model provides a long endoscopic forceps, including joint 1 and two handles 2, two handles 2 are connected through joint 1 sliding, handle 2 includes arc segment 4 and straight line segment 3, arc segment 4 is used for operator to hold, one end of straight line segment 3 is fixedly installed with two pincer mouth 7, in this embodiment, handle 2 and pincer mouth 7 are stainless steel material, and two pincer mouth 7 that are symmetrically arranged are adapted, and are used for operator to clamp, and the lower half of handle 2 is arranged as arc segment 4, compared with the force that the conventional circular ring type handle 2 can exert is greater, so that two pincer mouth 7 are combined and hold urethra more stably, and compared with a pair of conventional pincer mouth 7, in this embodiment, the clamping part is arranged as two pairs of pincer mouth 7, increases the clamping point, prevents the single clamping point from slipping and causes urethra to separate from pincer mouth 7.

[0026] As Figure 1 And Figure 3 Indicated, two arc segments 4 are symmetrically arranged, and one side of arc segment 4 is fixedly installed with wave-shaped plate 5, and wave-shaped plate 5 includes multiple protrusions and recesses.

[0027] One side of wave-shaped plate 5 is provided with multiple anti-skid grooves 15, and the multiple anti-skid grooves 15 on the same wave-shaped plate 5 are arranged at equal intervals.

[0028] It should be noted that the wave-shaped plate 5 and the anti-skid grooves 15 thereon are arranged to improve the stability of the operator's grip, and the conventional arc segment 4 has no protrusions on the outer side, which is prone to slipping.

[0029] The front side of the wave-shaped plate 5 is provided with a plurality of light-weight holes 6, and the plurality of light-weight holes 6 on the same wave-shaped plate 5 are evenly distributed, thereby reducing the weight of the wave-shaped plate 5 and the weight of the entire device.

[0030] As Figure 5 Indicated, one side of the pincer mouth 7 is provided with a notch 8, and the notches 8 on the two symmetrically arranged pincer mouths 7 are centrally symmetrically arranged, and the notches 8 can increase the contact area and friction between the pincer mouth 7 and the urethra, thereby reducing the risk of slipping.

[0031] As Figure 1 And Figure 2As shown in the figure, one side of the straight line segment 3 is provided with a fitting groove 9, and the two handles 2 abut each other through the two fitting grooves 9, and the fitting groove 9 is arranged so that the jaws 7 on the two handles 2 can be in the same plane.

[0032] As shown in the figure, Figure 2 , Figure 3 and Figure 4 As shown in the figure, the arc line segment 4 on the left side is fixedly installed with an arc-shaped cylinder 10 on one side, and the arc line segment 4 on the right side is fixedly installed with an arc-shaped plate 11 on one side, the arc-shaped plate 11 is slidingly installed in the arc-shaped cylinder 10, and the rotation of the two handles 2 is limited through the cooperation of the arc-shaped plate 11 and the arc-shaped cylinder 10, preventing the joint 1 from loosening to cause the handles 2 to be misaligned forward and backward, so that the gap 8 on the two jaws 7 exists, and finally leading to the fact that the grasping is not strict.

[0033] The arc-shaped spring 12 is fixedly installed on the inner wall of one side of the arc-shaped cylinder 10, one end of the arc-shaped spring 12 is fixedly installed with a positioning ball 13, one side of the arc-shaped plate 11 is provided with a hemispherical groove 14, the positioning ball 13 is matched with the hemispherical groove 14, when the two arc line segments 4 are held and the two handles 2 are rotated to be close to each other, the two handles 2 are limited to be closed through the cooperation of the arc-shaped spring 12 and the arc-shaped ball, and the position plays a supporting role to prevent the two pairs of jaws 7 from being completely closed, and a small opening is reserved for grasping the urethra, when the operator moves the jaws 7 to the specified position, the two arc line segments 4 are continuously compressed, thereby driving the two handles 2 to be close to each other until the two pairs of jaws 7 are completely closed.

[0034] Of course, the utility model also has other various implementation manners, based on the embodiment, other implementation manners obtained by the ordinary skilled in the art without any creative labor belong to the range protected by the utility model.
