DETAILED DESCRIPTION OF THE EMBODIMENTS

It is to be noted that the embodiments of the disclosure and the characteristics in the embodiments can be combined under the condition of no conflicts. The disclosure is described below with reference to the drawings and the embodiments in detail.

As shown inFIG.1toFIG.4, the knotter of the embodiments includes: a driving structure10, a punching and shearing clip20and scissors30. A clip mouth21of the punching and shearing clip20has a first position in an open state, and a second position in a punching state when driven by the driving structure10. The scissors30have a first position in an open state when driven by the driving structure10, and a second position in a shearing state when driven by the driving structure10. The second position of the scissors30is synchronized with the second position of the punching and shearing clip20.

Through disclosure of the technical solutions of the embodiment, when knotting a suture line, the driving structure10of the knotter drives the punching and shearing clip20to punch the clamping element100, thereby knotting the suture line, and at the same time, the driving structure10drives the scissors30to be in the shearing state, so that the scissors30may cut the knotted suture line. The scissors30are in the open state and the shearing state when driven by the driving structure10, and the structure is stable and reliable. The technical solution of the embodiment effectively solves the problem that the shearing knife of the knotter in the related art is unstable when cutting the suture line.

As shown inFIG.3, in the technical solution of the embodiment, a first end of the scissors30cooperates with the driving structure10, and cutting edges32of the scissors30are located at a second end of the scissors30. The scissors of the above structure are relatively low in processing cost and convenient to use. It is to be noted that the cutting edges32of the scissors30here are located at the second end of the scissors30, the second end does not just indicate an end part and may indicate a partial area between the second end of the scissors30and the first end of the scissors30, for example, the area from the pivot shaft31to the second end of the scissors30inFIG.3may be the cutting edges32entirely or may be the cutting edges32partially.

As shown inFIG.3andFIG.4, in the technical solution of the embodiment, the scissors30include a first scissor arm33and a second scissor arm34, middle parts of the first scissor arm33and the second scissor arm34are connected by a pivot shaft31, and the driving structure10cooperates with a first end of the first scissor arm33and a first end of the second scissor arm34. When the first end of the first scissor arm33is close to a second end of the second scissor arm34, a second end of the first scissor arm33is close to the second scissor arm34. The above structure is relatively low in processing cost, easy to mount and convenient to operate. Alternatively, the scissors30may be structured such that the first end of the first scissor arm33and the first end of the second scissor arm34are connected and form the pivot shaft31.

As shown inFIG.1andFIG.2, in the technical solution of the embodiment, the scissors30are located at one side of the punching and shearing clip20and arranged adjacent to the punching and shearing clip20. In this way, the distance between the scissors30and the punching and shearing clip20is relatively short, that is to say, the reserved length of the suture line is relatively short. After the suture line is clamped by a clamping element100and knotted, the suture line reserved from the clamping element100is the distance from the punching and shearing clip20to the scissors30. Particularly, the punching and shearing clip20is located at a left side, and the scissors30are located at the right side of the punching and shearing clip20.

As shown inFIG.1andFIG.2, in the technical solution of the embodiment, the driving structure10includes a driving rod12, and a first end of the driving rod12cooperates with both the punching and shearing clip20and the scissors30. The above structure is relatively low in processing cost. The punching and shearing clip20includes two clip arms which are oppositely arranged, and a first end of the driving rod12enables the punching and shearing clip20to punch the clamping element100through punching and shearing clip arms, thereby knotting. Particularly, a first side part121of the first end of the driving rod12has scissor arm holes11which cooperate with the scissors30, and the first end of the scissors30is located in the scissor arm holes11. The above structure is compact, and punching and shearing can be completed through the same driving rod12. When the middle parts of the first scissor arm33and the second scissor arm34of the scissors30have the pivot shaft, the scissor arm holes11include a first scissor arm hole111and a second scissor arm hole112, a first scissor arm33of the scissors30is located in the first scissor arm hole111, and a second scissor arm34of the scissors30is located in the second scissor arm hole112. A second side of the driving rod12and a first side of the driving rod12are of a stepped structure, and the second side of the driving rod12is shorter than the first side of the driving rod12. The driving rod12is a solid rod, the first scissor arm hole111and the second scissor arm hole112are respectively formed in oblique holes which cooperate with the first scissor arm33and the second scissor arm34, and the first scissor arm hole111and the second scissor arm hole112are through holes which penetrate through a side wall of the driving rod12from the first end of the driving rod12.

As shown inFIG.2, in the technical solution of the embodiment, a second side part122of the first end of the driving rod12has a punching and shearing clip abutting pressure plate13which cooperates with the punching and shearing clip20. The above structure is simple, and the knotting effect is good. Particularly, a bulged structure is arranged on an inner wall of the punching and shearing clip20, in this way, the clamping element100is better in clamping effect, and the suture line is not easy to run out. The clamping element100is a clamping nail. The suture line enters through the entrance hole50on the left side of the clamping element100. The suture line runs out of the sleeve40through the outlet hole51.

As shown inFIG.1andFIG.2, in the technical solution of the embodiment, the knotter further includes a handle and a sleeve40, a first end of the sleeve40is connected with the handle, the scissors30and the punching and shearing clip20are located at a second end of the sleeve40, and the driving rod12is located in the sleeve40. The second end of the driving rod12is connected with the handle. The above structure is convenient to operate and is compact in structure. The sleeve40can stretch into a body, in this way, the suture line reserved in the body is relatively short.

In the technical solutions (not shown in figure) of the embodiments, the knotter further includes a drive portion, and the drive portion is a manual drive portion arranged at the handle. The above structure is relatively low in processing cost. The manual drive portion is a trigger structure. Certainly, the drive portion may also be an automatic drive portion arranged at the handle. In this way, the knotter may be automatically driven, and the labor intensity of an operator is reduced. The automatic drive portion includes a motor, a hydraulic structure and the like. By operating a switch button arranged on the knotter, the motor runs or the hydraulic structure drives. Alternatively, an electric push rod structure may also be applied. It is to be noted that after primary knotting is completed, the driving structure10resets under the action of an elastic member or other power element in the handle, so that the scissors30recover from the shearing state to the open state and get ready for secondary knotting and line shearing operation.

The above descriptions are only preferred embodiments of the disclosure and are not intended to limit the disclosure. Those skilled in the art should understand that the disclosure may have various changes and modifications. Any modification, equivalent substitution, improvement and the like made within the spirit and principle of the disclosure should be included in the protection scope of the disclosure.
