[0034] An embodiment of the present application provides a surgical forceps. The following will be described in detail respectively.

[0035] Figure 1 A structural schematic diagram of one embodiment of the surgical forceps provided by the present application is shown in FIG. 1. As shown in FIG. 1, the surgical forceps 100 includes a body 110, which includes a first handle 111 and a second handle 112 hingedly connected to each other. A surgical staff member drives the first handle 111 and the second handle 112 to rotate relative to each other, so that the body 110 of the surgical forceps 100 clamps or releases the tissue of a patient or other medical devices, or the body 110 of the surgical forceps 100 can be used to distract or pressurize the tissue of the patient. Figure 1

[0036] Among them, the body 110 of the surgical forceps 100 can include two forceps heads 113, one of which is connected to the first handle 111, and the other of which is connected to the second handle 112. When the first handle 111 and the second handle 112 are rotated relative to each other, the two forceps heads 113 can be driven to move closer to or away from each other, so that the two forceps heads 113 clamp or release the tissue of a patient or other medical devices, or the two forceps heads 113 can be used to distract or pressurize the tissue of the patient. Of course, the surgical forceps 100 can also be used for other operations, which can be determined according to the purpose of the surgical forceps 100.

[0037] Continuing to refer to Figure 1 , the surgical forceps 100 can further include a limiting member 120, which is rotationally connected to the first handle 111, and the limiting member 120 can rotate relative to the first handle 111 about a first rotation axis X1 between a clamping position and a separation position. When the limiting member 120 is in the clamping position, it is clamped with the second handle 112 to limit the first handle 111 and the second handle 112 from moving closer to each other and / or moving away from each other. When the limiting member 120 is in the separation position, it is separated from the second handle 112.

[0038] ​Thus, by rotating the limiting piece 120 relative to the first jaw handle 111 around the first rotation axis X1 to the clamping position where the second jaw handle 112 is clamped, the first jaw handle 111 and the second jaw handle 112 cannot approach each other and / or move away from each other, the relative position of the first jaw handle 111 and the second jaw handle 112 is kept stable, and thus the surgical forceps 100 is kept at a predetermined position, which can be a position for clamping or loosening the tissue of a patient or other medical devices, or a position for distracting or pressing the tissue of a patient. Of course, the surgical forceps 100 can also be kept at other positions, which can be determined according to the use of the surgical forceps 100.

[0039] Correspondingly, by rotating the limiting piece 120 relative to the first jaw handle 111 around the first rotation axis X1 to the separation position where the second jaw handle 112 is separated, the limiting piece 120 can limit the first jaw handle 111 and the second jaw handle 112 to approach each other and / or move away from each other, so as to facilitate the operation of the surgical forceps 100 by the surgical personnel.

[0040] It should be noted that when the limiting piece 120 is in the clamping position where the second jaw handle 112 is clamped, the limiting piece 120 can limit the first jaw handle 111 and the second jaw handle 112 to approach each other, or limit the first jaw handle 111 and the second jaw handle 112 to move away from each other, or limit both the first jaw handle 111 and the second jaw handle 112 to approach each other and move away from each other, which can be determined according to the use or application scenario of the surgical forceps 100.

[0041] In some embodiments, as shown in Figure 1 the clamping structure 123 for clamping with the second jaw handle 112 can be arranged on one side of the limiting piece 120. When the limiting piece 120 is in the clamping position, the clamping structure 123 arranged on the limiting piece 120 clamps with the second jaw handle 112, so that the limiting piece 120 clamps with the second jaw handle 112.

[0042] In some embodiments, as shown in

[0043] the limiting piece 120 can be a rod-shaped structure, one end of the limiting piece 120 is rotationally connected with the first jaw handle 111, and the clamping structure 123 is a rack structure extending along the length direction of the limiting piece 120, one or more teeth of the rack structure are used for clamping with the clamping teeth of the second jaw handle 112, so that the limiting piece 120 clamps with the second jaw handle 112 to limit the first jaw handle 111 and the second jaw handle 112 to approach each other and / or move away from each other.

[0044] Continuing to refer to Figure 1The surgical forceps 100 can further include an elastic member 140 connected with the first handle 111, and the elastic member 140 is configured to directly or indirectly apply an elastic force to the limiting member 120 to drive the limiting member 120 to rotate from the separation position to the clamping position. Thus, the limiting member 120 can be stably kept in the clamping position by the elastic member 140, so that the surgical forceps 100 can be stably kept in the predetermined position.

[0045] Specifically, the elastic member 140 is arranged on the side of the first handle 111 facing the second handle 112, and the elastic member 140 includes an elastic portion 141 bent towards the second handle 112, which is configured to directly or indirectly apply an elastic force to the limiting member 120 to drive the limiting member 120 to rotate from the separation position to the clamping position. The elastic member 140 can be in a sheet structure, a rod structure or other structures, which are not limited herein.

[0046] In some embodiments, as shown in Figure 1 and Figure 2 The surgical forceps 100 can further include a rolling member 130 rotatably installed on the limiting member 120, and the rolling member 130 is configured to rotate relative to the limiting member 120 about a second rotation axis X2 different from the first rotation axis X1. The rolling member 130 rolls against the surface of the elastic member 140 facing the limiting member 120, and the elastic member 140 is configured to drive the limiting member 120 to rotate from the separation position to the clamping position by the rolling member 130.

[0047] The surgical forceps 100 provided by the embodiments of the present application rotatably installs the rolling member 130 on the limiting member 120, so that the first rotation axis X1 of the limiting member 120 relative to the first handle 111 is different from the second rotation axis X2 of the rolling member 130 relative to the limiting member 120, and the rolling member 130 rolls against the surface of the elastic member 140 on the first handle 111 facing the limiting member 120, so that the elastic member 140 can drive the limiting member 120 to rotate from the separation position from the second handle 112 to the clamping position clamping the second handle 112 by the rolling member 130. Moreover, since the elastic member 140 rolls against the rolling member 130, the friction is small, the elastic member 140 can smoothly drive the limiting member 120 to rotate from the separation position to the clamping position by the rolling member 130, and the limiting member 120 and the elastic member 140 are not prone to wear, the elastic member 140 and the limiting member 120 are not prone to jamming, and the reliability and service life of the surgical forceps 100 can be improved.

[0048] In the embodiments of the present application, the surgical forceps 100 can be any medical instrument having the first forceps handle 111, the second forceps handle 112, the limiting member 120 and the elastic member 140, such as hemostatic forceps, distraction forceps, compression forceps, etc., which are not limited herein. In addition, the rolling member 130 can include at least one of a roller, a ball and a bearing, as long as the rolling member 130 can rotate relative to the limiting member 120 about the second rotation axis X2 and the rolling member 130 can roll against the surface of the elastic member 140 facing the limiting member 120.

[0049] In some embodiments, as shown in Figures 2 to 4 The mounting groove 121 can be formed in the limiting member 120, and at least part of the rolling member 130 is located in the mounting groove 121. In this way, the connection between the rolling member 130 and the limiting member 120 can be more stable.

[0050] In some embodiments, the rolling member 130 can protrude from the outer surface 122 of the limiting member 120 and roll against the surface of the elastic member 140 facing the limiting member 120, so that the rolling member 130 and the elastic member 140 can roll against each other more conveniently. In addition, the elastic member 140 does not need to extend into the mounting groove 121 to roll against the rolling member 130, so that the size of the part (i.e., the elastic part 141) of the elastic member 140 used for rolling against the rolling member 130 can be larger, and the elasticity of the elastic member 140 can be stronger, which is beneficial to the stable retention of the limiting member 120 in the clamping position by the elastic member 140.

[0051] As shown in Figure 5 In some embodiments, part of the rolling member 130 can protrude from the end surface 1221, so that after the rolling member 130 rolls against the surface of the elastic member 140 facing the limiting member 120, the elastic member 140 can exert a force on the rolling member 130 with a longer force arm relative to the first rotation axis X1, and the elastic member 140 can more easily drive the limiting member 120 to rotate from the separated position to the clamping position.

[0052] As shown in Figure 1 and Figure 3As shown, one side of the limiting piece 120 is provided with a clamping structure 123 for clamping with the second handle 112, and the outer surface 122 of the limiting piece 120 includes an outer side surface 1222 located on the side of the limiting piece 120 away from the clamping structure 123. In some embodiments, another part of the rolling piece 130 can protrude from the outer side surface 1222. In this way, when the limiting piece 120 rotates by a large angle in the direction from the clamping position to the separation position, the rolling piece 130 can still roll against the side surface of the limiting piece 120 facing the elastic piece 140, reducing the risk of direct contact between the elastic piece 140 and the limiting piece 120 causing wear between the elastic piece 140 and the limiting piece 120.

[0053] Moreover, by making another part of the rolling piece 130 protrude from the outer side surface 1222, the distance between the first rotation axis X1 and the second rotation axis X2 can be increased, which is beneficial to increase the force arm of the force exerted by the elastic piece 140 on the rolling piece 130 relative to the first rotation axis X1, so that the elastic piece 140 can more easily push the limiting piece 120 to rotate from the separation position to the clamping position.

[0054] In some embodiments, the first rotation axis X1 and the second rotation axis X2 can be substantially parallel. In this way, when the limiting piece 120 rotates between the separation position and the clamping position, the rolling piece 130 will not slide against the surface of the elastic piece 140 facing the limiting piece 120 during rolling, which is beneficial to reduce the wear between the rolling piece 130 and the elastic piece 140, and further improve the service life of the surgical forceps 100.

[0055] In some embodiments, the second rotation axis X2 can be closer to the end surface 1221 than the first rotation axis X1, so as to make a part of the rolling piece 130 protrude from the end surface 1221. In addition, the second rotation axis X2 can be closer to the outer side surface 1222 on the side of the limiting piece 120 away from the clamping structure 123 than the first rotation axis X1, so as to make another part of the rolling piece 130 protrude from the outer side surface 1222.

[0056] It should be noted that the second rotation axis X2 can be closer to both the end surface 1221 and the outer side surface 1222 than the first rotation axis X1, or the second rotation axis X2 can be closer to only the end surface 1221 than the first rotation axis X1, or the second rotation axis X2 can be closer to only the outer side surface 1222 than the first rotation axis X1. Of course, the former can make the distance between the second rotation axis X2 and the first rotation axis X1 farther, which is beneficial to increase the force arm of the force exerted by the elastic piece 140 on the rolling piece 130 relative to the first rotation axis X1.

[0057] In some embodiments, as shown in FIG. 1, the second rotation axis X2 can be substantially parallel to the first rotation axis X1. In this way, when the limiting piece 120 rotates between the separation position and the clamping position, the rolling piece 130 will not slide against the surface of the elastic piece 140 facing the limiting piece 120 during rolling, which is beneficial to reduce the wear between the rolling piece 130 and the elastic piece 140, and further improve the service life of the surgical forceps 100. Figure 4As shown, the limiting member 120 can include two installation portions 124 arranged at intervals, and the rolling member 130 is located between the two installation portions 124. An installation groove 121 can be formed between the two installation portions 124, and by installing the rolling member 130 between the two installation portions 124, at least part of the rolling member 130 can be located in the installation groove 121.

[0058] The surgical forceps 100 can further include a pin shaft 131 penetrating the rolling member 130 and connected with the two installation portions 124, so that the rolling member 130 is stably rotationally installed on the limiting member 120.

[0059] Specifically, a first installation hole 1241 can be formed in each of the two installation portions 124, the pin shaft 131 penetrates the rolling member 130, and the two ends of the pin shaft 131 are inserted into the first installation holes 1241 of the two installation portions 124 one by one, so that the rolling member 130 is rotationally connected with the limiting member 120 through the pin shaft 131. The rolling member 130 can be made to rotate around the pin shaft 131, so that the rolling member 130 can rotate around the second rotation axis X2 relative to the limiting member 120. Alternatively, the pin shaft 131 can also be made to rotate in the first installation hole 1241 to drive the rolling member 130 to rotate around the second rotation axis X2 relative to the limiting member 120. The second rotation axis X2 coincides with the central axis of the pin shaft 131.

[0060] In some embodiments, the two installation portions 124 can be sequentially distributed along the extension direction of the first rotation axis X1, and the pin shaft 131 extends along the first rotation axis X1. In this way, the first rotation axis X1 and the second rotation axis X2 can be substantially parallel.

[0061] Specifically, a second installation hole 1242 can be formed in each of the two installation portions 124, and the first handle 111 is further provided with two connecting portions 1111 on the side facing the second handle 112, the two connecting portions 1111 are arranged at intervals along the first rotation axis X1, the two installation portions 124 are located between the two connecting portions 1111, and the two connecting portions 1111 are respectively provided with a connecting hole 1112. The surgical forceps 100 further includes a connecting shaft 150 penetrating the second installation holes 1242 of the two installation portions 124 and inserted into the connecting holes 1112 of the two connecting portions 1111, so as to rotationally connect the limiting member 120 with the first handle 111. The first rotation axis X1 coincides with the central axis of the connecting shaft 150.

[0062] In some embodiments, the gap between the rolling member 130 and the at least one mounting portion 124 can be greater than or equal to 0.2 mm to facilitate cleaning and disinfection of the gap between the rolling member 130 and the mounting portion 124. The gap between the rolling member 130 and the at least one mounting portion 124 can be 0.21 mm, 0.23 mm, 0.25 mm, 0.27 mm, etc.

[0063] In addition, the gap between the rolling member 130 and the at least one mounting portion 124 can be less than or equal to 0.3 mm to avoid the gap between the rolling member 130 and the mounting portion 124 being too large, which affects the stability of the rolling abutment between the rolling member 130 and the elastic member 140. The gap between the rolling member 130 and the at least one mounting portion 124 can be 0.22 mm, 0.24 mm, 0.24 mm, 0.28 mm, etc.
