Gun type circumcision and stitching instrument

Abstract

The invention discloses a gun type circumcision and stitching instrument. The gun type circumcision and stitching instrument is characterized by comprising a gun body, a handle, a trigger and a circumcision and stitching mechanism arranged in the gun body. The trigger is arranged at the junction between the lower portion of the gun body and the inner side of the handle and used for controlling the action of the circumcision and stitching mechanism. In an operation, a doctor squeezes the trigger with one hand, and the trigger drives a movement assembly in the circumcision and stitching mechanism to control a nail pushing assembly to move, so that an annular cutter and a stitching nail can be pushed synchronously almost, the redundant prepuce is cut off, and the stitching nail is stitched to the prepuce to stitch the incision. Acting points of the structure are evenly scattered, and the axis of an annular blade will not shift. The gun type circumcision and stitching instrument has the advantages that the structural strength is high, labor is saved in the triggering process, limited cutting is accurate, and the intraoperative and postoperative bleeding probability is greatly lowered; a new circumcision and stitching scheme which is high in operation precision, safe and reliable is provided clinically.

Description

technical field [0001] The invention relates to circumcision and suture surgical instruments, in particular to a circular circumcision and suture instrument with a gun-type structure. Background technique [0002] With the development of medical technology and clinical verification, the cutting and suturing principle of circumcision and suture has gradually been accepted by the clinical and academic circles. Compared with the traditional circumcision operation, the circumcision stapler has the advantages of cutting and suturing in one step. This method has the advantages of fast operation, less bleeding, less pain, and smooth cutting. At present, this type of circumcision suturing device has a body shape roughly similar to a "red wine opener" structure. However, this type of product has defects such as low cutting accuracy, low surgical quality and low surgical success rate due to its mechanical structure design. The disadvantages of this type of product are summarized as ...

AI Technical Summary

Problems solved by technology

Usually the doctor uses both hands or one hand to fire the handle, but no matter what the grip posture is, it is difficult to advance the handles distributed on both sides of the body simultaneously, that is, one side of the handle always advances first, and the gravity of the push rod shifts. Eventually, the axial center of the circumcision knife will deviate, resulting in failure to cut through the line. The doctor needs to use a scalpel to complete the cut, or directly cut out the position of the staples other than the anvil, resulting in failure or partial failure of the operation.

[0004] 2. Since there is no cutting depth limiting device, the firing force and cutting depth are completely judged by the doctor's experience. Often, the cutting is too deep, causing the cutting knife to sink deeply into the anvil and cannot be pulled out, or the cutting force is too small , the foreskin is too long to be cut off, and the second shot can no longer be performed, resulting in a complete failure of the operation

[0005] 3. At present, the connection between the glans cap and the pull rod of this type of product is realized by plastic. During the cutting process, the connection part is often broken and damaged due to the continuous cutting force, making it impossible to perform surgery or operations. fail

[0006] And because the ring cutter and the plastic mandrel are welded and fixed by hot-melt riveting, when the cutting is completed and the knife is retracted, the riveting point is brittle and falls off, so that the ring cutter and the foreskin are still embedded on the anvil, and the retraction cannot be realized. The embarrassment of the knife, which leads to the failure or partial failure of the operation
