[0048] See also Figure 3 The rotating wheel 120 includes a rotating part 121 and a sliding rod connecting part 122. In this embodiment, the rotating part 121 is a hollow structure, and its inner wall is connected to the outer wall of the sliding rod connecting part 122, so that the sliding rod connecting part 122 can be driven to rotate together when the rotating part 121 rotates. The two ends of the sliding rod connecting part 122 extend out of the rotating part 121, and there are two first mounting grooves 113 for placing the two ends of the sliding rod connecting part 122, so that the sliding rod connecting part 122 can rotate in the two first mounting grooves 113. The sliding rod connecting part 122 is connected to a hollow structure and connected to the inside of the rotating part 121; the sliding rod connecting part 122 is used to connect with the sliding rod 130, and assist the sliding rod 130 to translate and rotate. The hollow structure of the sliding rod connecting part 122 is the same as the structure of the rotating sliding rod 131, and the cross-section is non-circular. Among them, there are many options for non-circular, including but not limited to notches, protrusions, squares, polygons, etc., as long as it can achieve cooperative sliding but not rotating. In this embodiment, the surface of the rotating part 121 is provided with an anti-slip part 123, and the anti-slip part 123 is a structure such as an anti-slip groove, anti-slip pattern, and anti-slip protrusion, which can improve the gripping force and facilitate the doctor to better control the rotation of the rotating part 121.

[0049] See also Figure 4 The slide bar 130 includes a rotating slide bar 131 and a grabbing mounting end 132 and a sliding driving end 133 mounted at both ends of the rotating slide bar 131. The rotating slide bar 131 is slidably inserted in the slide bar connection part 122 and can rotate with the rotation of the slide bar connection part 122. The grabbing mounting end 132 is used to connect with the core wire in the grabbing end 210, and the sliding driving end 133 is connected to the connecting rod assembly 150. Since the shapes of the rotating slide bar 131 and the slide bar connection part 122 match and are not circular structures, the slide bar connection part 122 can drive the rotating slide bar 131 to rotate when rotating, and at the same time, it does not affect the sliding of the rotating slide bar 131 in the slide bar connection part 122. The connection between the grabbing mounting end 132 and the core wire can be a fixed connection or a detachable connection, such as welding, etc., and the detachable connection can be a snap connection, plug-in connection, etc. Specifically for this embodiment, this embodiment provides a typical but non-limiting example, the grabbing and mounting end 132 is provided with a mounting groove 134 for connecting the core wire, the core wire is embedded in the mounting groove 134, the mounting channel 117 is connected to the mounting groove 134, the core wire in the outer tube can enter the mounting groove 134 through the mounting channel 117 and be embedded in the mounting groove 134, the mounting groove 134 is used to fix the core wire, and then the movement and rotation of the core wire are controlled, and then the opening and closing and rotation of the grabbing end 210 are realized. The sliding drive end 133 can slide in the second mounting groove 114 through the control of the connecting rod assembly 150, and then drive the rotating sliding rod 131 to slide. The sliding drive end 133 includes a first baffle 135, a clamping shaft 136 and a second baffle 137. The first baffle 135 is connected to the rotating sliding rod 131, and the clamping shaft 136 is connected between the first baffle 135 and the second baffle 137. The diameter of the clamping shaft 136 is smaller than the diameter of the first baffle 135 and the second baffle 137 to form an installation area 138 for inserting the connecting rod assembly 150.

[0050] See also Figure 5 The handle 140 includes a rotating arm 141 and a double-arm push-pull portion 142, wherein the end of the handle 140 extending into the housing 110 is the rotating arm 141, and the double-arm push-pull portion 142 is located outside the housing 110, and the rotating arm 141 is rotatably connected to the housing 110. Specifically, the rotating arm 141 is rotatably sleeved on the first mounting shaft 111 to realize the rotatable connection between the handle 140 and the housing 110. The double-arm structure of the double-arm push-pull portion 142 is more convenient for doctors to operate. When in use, the doctor can buckle his fingers into it, and the doctor can easily push or pull the handle 140. The reasonable lever ratio of the handle 140 can save more effort when pushing and pulling.

[0051] See also Figure 1 and Figure 6The connecting rod assembly 150 includes a first connecting rod 151 and a second connecting rod 152. One end of the first connecting rod 151 is rotatably connected to the sliding driving end 133, and the other end of the first connecting rod 151 is rotatably connected to the housing 110. Specifically, a groove 153 is provided at one end of the first connecting rod 151 rotatably connected to the sliding driving end 133. The mounting area 138 of the sliding driving end 133 is used for inserting the groove 153. At this time, the clamping shaft 136 is embedded in the groove 153. The matching of the clamping shaft 136 and the groove 153 realizes the connection between the first connecting rod 151 and the sliding rod 130, and then the movement of the first connecting rod 151 drives the sliding rod 130 to move. The other end of the first connecting rod 151 is rotatably sleeved on the second mounting shaft 112 to realize the rotational connection between the first connecting rod 151 and the housing 110. One end of the second connecting rod 152 is rotatably connected to the middle part of the first connecting rod 151, and the other end of the second connecting rod 152 is rotatably connected to the middle part of the handle 140. When the handle 140 is pushed or pulled, the second connecting rod 152 can be driven to move, thereby driving the first connecting rod 151 and the sliding driving end 133 to move forward and backward.

[0052] The working principle of the gun-shaped handle 100 provided in this embodiment is: the core wire of the slide bar 130 is connected to the gripping end 210 to control the opening, closing and rotation of the gripping end 210 by controlling the forward and backward movement and rotation of the slide bar 130. The forward and backward movement of the slide bar 130 is controlled by the handle 140 and the connecting rod assembly 150. During operation, the doctor puts his fingers into the handle 140 to push or pull the handle 140. At this time, the handle 140 rotates relative to the housing 110, thereby driving the second connecting rod 152 connected thereto to rotate. During the rotation process, the second connecting rod 152 transmits the thrust or pulling force to the first connecting rod 151 and the slide bar 130 connected to the first connecting rod 151, thereby realizing the forward and backward movement of the slide bar 130, and finally controlling the opening and closing of the gripping end 210. The rotation of the slide bar 130 is controlled by the rotating wheel 120. The rotating slide bar 131 of the slide bar 130 is installed in the slide bar connecting portion 122 of the rotating wheel 120. The rotating slide bar 131 can rotate with the rotation of the slide bar connecting portion 122, and does not affect the forward and backward movement of the rotating slide bar 131. When the gripping end 210 needs to be rotated, only the rotating portion 121 of the rotating wheel 120 needs to be rotated to drive the slide bar connecting portion 122 and the rotating slide bar 131 to rotate. Therefore, the gun-shaped handle 100 provided in this embodiment can simultaneously realize the control of the opening and closing and rotation of the gripping end 210, and can be operated with one hand, which is more convenient.

[0053] Second embodiment

[0054] Please refer to Figure 7The present embodiment provides a medical grasping clamp 200, which includes a grasping end 210 and the gun-type handle 100 provided in the first embodiment, and the grasping end 210 is connected to the grasping mounting end 132 of the gun-type handle 100. The grasping end includes a biopsy forceps, a tissue forceps, a foreign body forceps, a hemostatic clip or a snare. The gun-type handle 100 provided in the present embodiment can be matched with a variety of grasping ends, and has a wide range of applications.

[0055] In summary, the gun-shaped handle 100 provided by the utility model utilizes the core wire connection of the slide bar 130 and the gripping end 210 to realize the control of the opening, closing and rotation of the gripping end 210 by controlling the forward and backward movement and rotation of the slide bar 130. Among them, the forward and backward movement of the slide bar 130 is controlled by the handle 140 and the connecting rod assembly 150. When the handle 140 rotates relative to the housing 110, it can drive the connecting rod assembly 150 connected thereto to move, thereby realizing the transmission of thrust or pulling force to the slide bar 130 connected to the connecting rod assembly 150, so that the slide bar 130 moves forward and backward, and finally controls the opening and closing of the gripping end 210. The rotation of the slide bar 130 is controlled by the rotating wheel 120. The rotating slide bar 131 of the slide bar 130 is installed in the slide bar connecting part 122 of the rotating wheel 120. The rotating slide bar 131 can rotate with the rotation of the slide bar connecting part 122, and does not affect the forward and backward movement of the rotating slide bar 131. When the gripping end 210 needs to be rotated, only the rotating part 121 of the rotating wheel 120 needs to be rotated to drive the slide bar connecting part 122 and the rotating slide bar 131 to rotate. Therefore, the gun-shaped handle 100 provided in this embodiment can simultaneously realize the control of the opening and closing and rotation of the gripping end 210, and can be operated with one hand, which is more convenient. The gun-shaped handle 100 can be matched with a variety of gripping ends 210, and its application range is wide.
