Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-7, an anastomat for reducing restoring force by linear cutting comprises a support frame 1 and a cover plate 2, wherein the support frame 1 is fixedly connected with the cover plate 2, a slide block 4 is arranged at the top of the support frame 1 in a sliding manner, a through groove 41 is formed in one side of the slide block 4, a push button 3 is embedded in the through groove 41, a cam 5 is rotatably arranged at the top of the support frame 1, a claw part 53 which is of an integrated structure is fixedly arranged at one side of the cam 5, a groove hole matched with the claw part 53 is formed in the tail end of the slide block 4, a U-shaped groove is formed in the top of the support frame 1, and through the arrangement of structures such as a first splayed rib 201, a second splayed rib 202, a first boss 51 and a second boss 52, when the push button 3 and the slide block 4 are reset, the bosses move from the wide ends to the narrow ends of the splayed ribs, so, the slide block 4 is connected with the inside of the U-shaped groove in a sliding way, one side of the support frame 1 is provided with a long groove 101, the part of the push button 3 passes through the inside of the long groove 101, both sides of the support frame 1 are provided with round holes 102, a bolt 6 is embedded in the round holes 102, the cam 5 is sleeved outside the bolt 6, the cam 5 is also provided with a first boss 51 and a second boss 52 which are of an integrated structure respectively, the inner wall of the cover plate 2 is provided with a first splayed rib 201 and a second splayed rib 202 which are of two groups of integrated structures respectively, through the arrangement of the first splayed rib 201, the second splayed rib 202, the first boss 51, the second boss 52, the sliding block 4, the push button 3 and other structures, the push button 3 is fixed on one side of the sliding block 4, when the surgical operation is performed at the initial position, the first boss 51 is in interference fit with the narrow end of the first splayed rib 201, so that the position of the cam 5 can be locked, the push button 3 is prevented from moving in a string manner to cause misoperation, and the surgical risk is greatly reduced.

In this embodiment, when the device is used, when the slider 4 is at the initial position, the claw portion 53 on the cam 5 is buckled in the slot at the tail end of the slider 4, and meanwhile, the first boss 51 on the cam 5 is in interference fit with the narrow end of the first rib 201 on the cover plate 2, so that the cam 5 can be prevented from rotating, the slider 4 and the push button 3 are locked, when the push button 3 is forced forward, the slider 4 is driven to move forward, the cam 5 is pushed to rotate, the first boss 51 and the second boss 52 on the cam 5 respectively pass through the first rib 201 and the second rib 202 on the cover plate 2, and at this time, because the bosses move from the narrow ends to the wide ends of the ribs, the forward thrust force is large, the second boss 52 contacts with the wide end of the second rib 202, and simultaneously, the slot of the slider 4 is separated from the claw portion 53 of the cam 5.

Further, the push button 3 is forced to move backwards, and then the slide block 4 is driven to move backwards, when the slide block 4 touches the hook part 53 of the cam 5, the second boss 52 on the cam 5 is driven to pass through from the wide end to the narrow end of the second splayed rib 202 on the cover plate 2, and when the push button 3 continuously returns to the initial position, the first boss 51 on the cam 5 passes through from the wide end direction of the first splayed rib 201 on the cover plate 2 to the narrow end, and in the process, the boss moves from the wide end to the narrow end of the splayed rib, so that the restoring force of the push button 3 is small.

In conclusion, the cam 5 can be locked by the splayed rib on the cover plate 2 at the initial position and is not easy to move through the measures, so that the sliding block 4 and the push button 3 are fixed, misoperation can be avoided, and meanwhile, when the push button 3 and the sliding block 4 need to be reset, the required restoring force is smaller, and the purpose of reducing the restoring force is achieved.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
