Disposable intracavity cutting stapler with percussion transmission device

Abstract

The invention discloses a one-time-use intracavity cutting stapler with a firing transmission device. The stapler includes a handle, a pliers head, a plectrum, a firing rod, an anastomotic nail, and a cutter. One end of the handle is provided with a pliers head. Set the cutting knife and several staples, one end of the firing rod is located in the handle, the other end is located in the pliers head, the paddle is set in the handle and can slide axially along the handle, the firing rod is moved toward the pliers head by the force of the paddle to make the cutting knife advance As well as anastomosis with staples, the stapler also includes a rod pin and a power storage spring. A second lock hole is set at the end of the trigger rod. The rod pin is inserted from the side of the handle and passes through the second lock hole. One end of the power storage spring is connected to the plectrum and the other end is connected to the firing rod. . The cutter is of rolling cutting type. In the present invention, the flesh cutting process is carried out by a rolling cutter, and the traction force received by the flesh tissue is directed toward the cutting site during the cutting process, and the staples are ensured to be stapled with the flesh tissue to prevent nail detachment from occurring.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to a disposable intracavity cutting stapler with a firing transmission device. Background technique [0002] Stapler is a commonly used surgical instrument, which is widely used in the operations of organs and tissues such as digestive tract, respiratory tract and genitourinary organs. It is especially suitable for the anastomosis of organs and tissues that are difficult to expose and operate. The operation time is reduced, and compared with the traditional suture, the operation quality is greatly improved. [0003] Although most of the staplers in the prior art are cutting and stapling, there is still a certain sequence of these two actions, because if the stapling is done first, it is easy to pull the staple at the position of the staple during the cutting process. cause damage, so basically all are cut first and then stapled.

Problems solved by technology

[0003] Although most of the staplers in the prior art are cutting and stapling, there is still a certain sequence of these two actions, because if the stapling is done first, it is easy to pull the staple at the position of the staple during the cutting process. cause damage, so basically all are cut first and then stapled. The cutting knife of the prior art moves in a straight line and cuts. The position of the tissue incision is at an acute angle, and the subsequent stapling may not be sufficiently stapled, resulting in the detachment of the staples, which is very unfavorable to the surgical process. Moreover, the basic disposable staplers are manually pushed forward by the firing rod. , the strength and speed of hand force directly determine the strength and speed of the anastomosis process, which is easy to affect the unevenness of the anastomosis site and affect the quality of anastomosis
