Description

Technical Field

[0001] The utility model relates to a gastroscope stapler and a head component. Background Art

[0002] Gastroscopy is a medical examination method, and also refers to the instrument used for this examination. It uses a thin, soft tube to extend into the stomach, so that doctors can directly observe the lesions of the esophagus, stomach and duodenum, especially the tiny lesions. Gastroscopy can directly observe the true condition of the examined area, and can also perform pathological biopsy and cytological examination on the suspected lesions to further clarify the diagnosis. It is the preferred examination method for upper gastrointestinal tract lesions.

[0003] Currently, gastroscopy can be used to observe the internal structure of organs and perform some simple ligation operations. However, when a large wound is formed after ligation, suturing cannot be performed under gastroscopy, so the patient needs to be sutured surgically, which leads to more workload. Currently, there is an urgent need for a device that can perform suturing under gastroscopy. Utility Model Content

It then extends along the wire slot to the through hole of the circular protrusion, extends upward through the through hole of the second splicing block, and is connected to the bottom end of the tension spring in the through slot. The left cable is pulled to make the slider head move clockwise (rebound movement); the right cable passes through the corresponding mounting holes on the slider head in sequence, passes through the slider slot, and is placed in the wire slot. It then extends along the wire slot to the through hole of the circular protrusion, extends upward through the through hole of the second splicing block, and is connected to the connecting block in the through slot. The right cable is pulled to make the slider head move counterclockwise (stitching movement). During the stitching movement, the user pulls the bracelet backwards. Since the connecting block and the dial block are stuck in the bracelet, they move with the bracelet. The left cable is fixed on the connecting block. When the connecting block moves, the left cable also moves. At this time, the right cable, which is on the same line as the left cable, is stretched to drive the tension spring, causing the tension spring to deform. During the rebound movement, the user manually turns on the rebound switch to make the tension spring rebound, drive the right cable to move, and restore the left cable to its initial position.

Both the first slot and the second slot are through slots for easy installation of the shift block. A rebound switch 138 is installed at the outer ends of the first and second slots. When the rebound switch is turned, the slider head moves clockwise. When the rebound switch is not turned, the teeth at the insertion end of the shift block are engaged with the rack, and the tension spring is in a stretched state; after the rebound switch is turned, the teeth at the insertion end of the shift block are out of contact with the rack, and the tension spring rebounds.

[0043] A cover plate 15 is provided at the opening of the through slot on one side of the tension spring.

The spring tube is flexible and moves with the movement of the gastroscope. When in use, the movement of the gastroscope drives the spring tube to move, and by adjusting the fixing switch, the length of the spring tube is controlled, so that the spring tube drives the first pin to rotate around the pin, so that the head assembly rotates.
