[0012] The return assembly of the manual laparoscope stapler of the utility model is engaged with the left return button and the right return button through the locking step, so that the return button is securely installed and the return button is prevented from falling off due to forcible pulling. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative work, among which:

[0014] Figure 1 It is a structural schematic diagram of a preferred embodiment of a recovery component of the manual laparoscopic stapler of the utility model;

[0015] Figure 2 is a schematic diagram of the structure of the connecting pin;

[0016] Figure 3 is a schematic diagram of the structure of a manual laparoscopic stapler equipped with a recovery assembly;

[0017] The markings of the components in the accompanying drawings are as follows: 1. connecting pin, 11. locking step, 2. left return button, 3. right return button, 4. rack. DETAILED DESCRIPTION

[0018] The technical scheme in the embodiment of the utility model will be described clearly and completely below. The structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the content disclosed in the specification, so that people familiar with this technology can understand and read, and are not used to limit the limiting conditions that can be implemented in the utility model, so they have no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that can be produced by the utility model and the purpose that can be achieved, should still fall within the scope of the technical content disclosed in the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of narration, and are not used to limit the scope that can be implemented. The change or adjustment of its relative relationship should also be regarded as the scope that can be implemented in the utility model without substantially changing the technical content.

[0019] See also Figures 1 to 3A manual laparoscopic stapler recovery assembly includes a connecting pin 1, a left recovery button 2 and a right recovery button 3. The connecting pin 1 is connected to a rack 4 of the manual laparoscopic stapler. The manual laparoscopic stapler can adopt an existing stapler, which will not be described in detail here.

[0020] The connecting pin 1 is embedded in the fixing pin hole of the rack 4. The cross-sections of the fixing pin hole and the connecting pin 1 are both square. The square structure can ensure that the connecting pin 1 and the rack 4 are fastened, and prevent the connecting pin 1 from rotating relative to the rack 4, thereby ensuring the stability of the position of the return button. Of course, the cross-sections of the fixing pin hole and the connecting pin 1 can also be rectangular, diamond or other special-shaped structures that can be fixed.

[0021] At least one locking step 11 is provided at the left and right ends of the connecting pin 1, and the conical step is embedded in the left return button 2 and the right return button 3 to fix the connecting pin 1 to the left return button 2 and the right return button 3. The locking step 11 is a conical step. The number of conical steps is 2 or 3. Positioning holes that cooperate with the connecting pin 1 are provided on the left return button 2 and the right return button 3, and the inner side of the positioning hole has a locking hole that cooperates with the conical adjustment. The connecting pin 1 is correspondingly inserted into the positioning hole, and the return button is pressed into the connecting pin 1 from both sides through the pressing tool to ensure that the conical step is pressed into the positioning hole to achieve the fastening between the connecting pin 1 and the return button. In this way, the connecting pin 1 can be driven to move by pulling the return button, thereby realizing the retreat of the rack 4, and the position of the rack 4 can be manually restored.

[0022] The upper ends of the left return button 2 and the right return button 3 are connected to each other through a connecting buckle. The left return button 2 and the right return button 3 are tightly connected, which is convenient for the user to pull the return button by hand, thereby improving the comfort and accuracy of operation.

[0023] Different from the prior art, the recovery assembly of the manual laparoscopic stapler of the utility model is simple to install, has a firm structure, is safe and reliable, is easy to operate, and has a low manufacturing cost.

[0024] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
