Embodiment Construction

[0039]In order to use the same instrument to complete the purse string suture, cutting and suturing, simplify the operation process of the tissue (especially the lumen tissue) that needs purse string suture, reduce the operation time, risk and pain of the patient, and further be able to use For laparoscopic surgery, an embodiment of the present invention provides an end effector and a surgical instrument. In the technical solution of the present invention, the suturing mechanism on one side of the end effector can realize tissue suturing, the purse-string suturing mechanism on the other side can realize tissue purse-string suturing, and the cutting mechanism between the suturing mechanism and the purse-string suturing mechanism can realize Realize tissue cutting, use the end effector or the surgical instrument provided by the embodiment of the present invention to realize the purse-string suture of the tissue at the retained end of the lumen, as well as the cutting and suturing...

Abstract

The invention relates to the technical field of medical equipment, and discloses an end effector, a surgical operating instrument and purse-string forceps. By means of the end effector, the surgical operating instrument and the purse-string forceps, purse-string nails can be made to be connected with lumen tissue firmly, and the risk that the lumen tissue is pierced through is completely avoided; the end effector and the surgical operating instrument can further simplify the operation process of an operation and relieve trauma brought to a surgery patient. The end effector comprises a first forceps arm, a second forceps arm, a suture mechanism, a purse-string suture mechanism and a cutting mechanism, wherein the suture mechanism is arranged on one side of the longitudinal direction of the two forceps arms, the purse-string suture mechanism is arranged on the other side of the longitudinal direction of the two forceps arms and the cutting mechanism is arranged between the suture mechanism and the purse-string suture mechanism. The purse-string suture mechanism comprises a first purse-string nail box arranged on the first forceps arm, a second purse-string nail box arranged on the second forceps arm and a double-sided nail anvil located between the two purse-string nail boxes, the purse-string nails are arranged in the two purse-string nail boxes respectively, and the surfaces, facing the double-sided nail anvil, of the two purse-string nail boxes are provided with purse-string lines.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an end effector, a surgical instrument and a purse forceps. Background technique [0002] Gastrointestinal surgery usually requires cutting off the lumen of the closed tissue, and performing a purse string suture on the side of the disconnected lumen. The purse string suture is used to fit the anvil of the circular stapler, so that the circular stapler can be used for subsequent surgery. Anastomosis and other operations. [0003] The purse-string suture is a common suturing technique in surgery, and two main purse-string sutures are known. One way is to perform a purse-string suture by hand, as in Figure 1a , Figure 1b As shown, the doctor first uses a purse-string needle to pass through the tissue surface around the incision of the lumen tissue 59 with the purse-string 58 , and then tightens the purse-string 58 to complete the purse-string suture. The manual sut...
