SPECIFIC EMBODIMENT

[0018] The utility model will be further explained in combination with the specific embodiment and the accompanying drawings.

[0019] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0020] It should be noted that the terms used herein are only for the purpose of describing the specific embodiment, and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form, and in addition, it should be understood that when the terms "comprise" and / or "include" are used in the specification, there is a feature, step, operation, device, component and / or their combination.

[0021] As Figures 1-2As shown, the embodiment provides a surgical grasping structure with an intermediate lock 12, comprising a left grasping rod 5 and a right grasping rod 6, the top ends of the left grasping rod and the right grasping rod are hingedly connected to each other, and the bottom ends form a grasping opening, the inner sides of the left grasping rod and the right grasping rod are fixedly provided with front and rear distributed clamping rods 13, the clamping surfaces of the front and rear adjacent clamping rods are engaged through sawtooth 14, and the engagement direction between the sawtooth is left and right.

[0022] In the embodiment of the utility model, the outer side of the left grasping rod and the right grasping rod is fixedly provided with an outer convex handle 15 at the position corresponding to the clamping rod.

[0023] In the embodiment of the utility model, the overall outer contour shape of the grasping structure 1 composed of the left grasping rod and the right grasping rod is a water drop shape with narrow upper and wide lower.

[0024] In the embodiment of the utility model, the clamping rod and the outer convex handle are arranged at the middle upper part of the water drop-shaped grasping structure.

[0025] The water drop-shaped grasping structure is more in line with ergonomics during use, especially the clamping rod and the outer convex handle are arranged at the middle upper part of the water drop shape, the width of this part is just right, which is convenient for holding and operating, and the appearance and comfort of the grasping structure are improved.

[0026] In the embodiment of the utility model, the upper part of the grasping structure composed of the left grasping rod and the right grasping rod is provided with a suspension piece 2, the suspension piece and the grasping structure are connected through a universal joint 3, so as to facilitate the universal adjustment of the grasping structure.

[0027] In the embodiment of the utility model, the suspension piece is a suspension rod, and the suspension rod is installed on the main body 4 of the surgical suspension system.

[0028] In the embodiment of the utility model, the universal joint comprises a connecting rod 7 fixed at the top of the hinge joint point of the left grasping rod or the right grasping rod, a ball head 8 fixedly arranged at the end of the connecting rod, a bottom end of the suspension piece is provided with an embedded through hole 9, and the ball head is embedded in the embedded through hole.

[0029] In the embodiment of the utility model, the bottom end of the suspension piece has a lower bending part 10, the embedded through hole is arranged on the lower bending part, and the outer periphery of the embedded through hole is connected to the outside through an embedded notch 11.

[0030] In the embodiment of the utility model, the inner diameter of the embedded through hole is greater than the width of the embedded notch, but less than the outer diameter of the ball head; and the width of the embedded notch is equal to the outer diameter of the connecting rod.

[0031] When installing the ball head, the connecting rod first passes the embedding gap into the embedding through hole, and then the ball head is placed on the embedding through hole, and since the outer diameter of the ball head is larger than the inner diameter of the embedding through hole, the ball head will not fall down. The rotation of the ball head in the embedding through hole can realize universal connection, thereby expanding the operation space.

[0032] In the embodiment of the utility model, the working principle of the surgical grasping and pricking structure with intermediate lock catch is:

[0033] When the surgical grasping and pricking structure with intermediate lock catch is used, the operator holds the left grasping rod close to the clamping rod with the left hand and holds the right grasping rod close to the clamping rod with the right hand, and then slightly uses force to break the left and right grasping rods forward and backward, so that the left and right grasping rods can be elastically deformed to a certain extent to realize the disengagement of the sawteeth of the left and right grasping rods, and at the same time, the operator can open the grasping and pricking structure with both hands, so that the grasping and pricking structure can be opened to prepare for grasping the skin tissue. Next, the operator can operate the grasping and pricking structure from opening to closing with one hand by relying on the outward convex handle.

[0034] When the grasping and pricking structure needs to be closed, the operator only needs to hold the left and right grasping rods tightly with one hand, and the two clamping rods are close to each other and abut against each other forward and backward until the clamping engagement, and after the engagement is in place, the grasping opening is also clamped in place, and under the constraint of the sawteeth engagement, the left and right grasping rods are not easy to be loosened left and right, and the skin tissue can be clamped.
