The present application belongs to the technical field of medical instrument processing device, especially relates to a welding equipment for continuous firing ligation clip cartridge. The present application aims at the problem that most of the existing technologies use laser welding equipment for welding by manual holding of products, which results in low welding efficiency and high work intensity. The welding equipment for continuous firing ligation clip cartridge comprises a mounting platform, a driving mechanism for moving a laser welding head is arranged on the mounting platform, the laser welding head is connected to the driving mechanism, a clamp assembly for fixing the cartridge is located on one side of the driving mechanism and is fixedly connected with the mounting platform, and the laser welding head can be moved to be located directly above the clamp assembly. The present application provides a welding equipment specially used for welding between the cartridge shell and the positioning steel wire of the cartridge, which improves the work efficiency and reduces the work intensity compared with the manual welding method in the prior art.

The invention relates to the technical field of medical instruments, in particular to a continuous clip applier which comprises a loading mechanism and a clip applying mechanism, a ligation clip is placed in a loading device, the ligation clip is extruded to be in a semi-closed state through a side pressing plate, an upper pressing plate presses a propelling part and the ligation clip into a magazine, and an upper sleeve and a lower sleeve are buckled to achieve assembling of a magazine assembly; the box magazine assembly is inserted into the outward extending pipe and can rotate by 360 degrees along with the hand wheel, the trigger is pulled to drive the outward extending pipe to move, the outward extending pipe extrudes the tong head in the box magazine assembly to enable the tong head to be closed, and buckling of the ligation clamp is achieved. The overhanging tube is reset through the first spring, and the forceps head is reset through the U-shaped spring; the shifting fork drives the bullet changing device to move so as to drive the propelling part to move forwards in the magazine, the propelling part pushes the next ligation clip to the position of the previous ligation clip, rapid bullet feeding and bullet feeding are achieved, meanwhile, the counting plate is driven to move, the number on the counting plate corresponds to the number of the remaining ligation clips in the magazine, and synchronous display is achieved.

This invention proposes a clamping device, a clamp applicator, and a clamp delivery monitoring method. The clamping device includes a clamping chamber, clamps to be delivered located between two adjacent first elastic clamping positions within the clamping chamber, and a first communication interface for communication with a handle. When the clamps to be delivered are not under the action of the push clamp, each clamp can move between a first position and a second position. Each clamp is equipped with a magnet. When the clamps to be delivered are not under the action of the push clamp, the magnet of each clamp can move from the first position to the second position. A Hall effect linear element is provided on the clamping chamber base plate at the center of the movement trajectory of each clamp's magnet from the first position to the second position. All Hall effect linear elements are electrically connected to the first communication interface. This provides a structural basis for clamp delivery monitoring.

The invention discloses a disposable continuous shooting clip applier with a ligature clip, which relates to the technical field of medical instruments and comprises a handle with a percussion trigger, a clip tube, a fixing plate sleeved in the clip tube, a clip head mounted at the front end of the fixing plate and a pop-up clip bin arranged on the fixing plate. A plurality of ligation clips are arranged in the pop-up clip bin along the direction from the handle to the forceps head, and enter the clip applying position of the forceps head through the clip supplementing position; a pop-up limiting unit is arranged close to the outlet end of the pop-up clip bin, a position covering limiting unit is arranged at the outlet facing the clip applying position, and clip applying limiting units are arranged on the inner sides of the two clamp arms. The percussion trigger has a percussion self-resetting function, and drives the clamp arm, the pop-up limiting unit, the complement limiting unit and the clip applying limiting unit to act in a linkage manner, so as to control the ligature clip to enter a clip complement position and a clip applying position in sequence and be released by the clamp head; effective separation of clip feeding positioning and closed clip applying processes is realized, action interference is reduced, and stability, continuous firing reliability and closing consistency of the ligature clip in a clip applying position are improved.

The application discloses a one-time use band ligature clamp continuous firing clamp forceps, and relates to the technical field of medical devices, which comprises a handle with a firing trigger, a clamp pipe, a fixed plate sleeved in the clamp pipe, a clamp head installed at the front end of the fixed plate, and a pop-up type clamp warehouse arranged on the fixed plate; a plurality of ligature clamps are arranged in the pop-up type clamp warehouse in the direction from the handle to the clamp head, and the ligature clamps enter the clamp position of the clamp head through the supplementary clamp position; a pop-up limiting unit is arranged adjacent to the outlet end of the pop-up type clamp warehouse, a supplementary position limiting unit is arranged at the outlet facing the clamp position, and a clamp limiting unit is arranged in the inner side of the two clamp arms; the firing trigger has a firing self-resetting function and drives the clamp arms, the pop-up limiting unit, the supplementary position limiting unit and the clamp limiting unit to move in linkage, so that the ligature clamps enter the supplementary clamp position and the clamp position in sequence and are released by the clamp head; the effective separation of the clamp positioning and the closing clamp process is realized, the action interference is reduced, and the stability of the ligature clamps in the clamp position, the continuous firing reliability and the closing consistency are improved.

The invention relates to a ligature clip capable of puncturing. The ligature clip comprises a connecting part; the upper arm and the lower arm are connected through a connecting part to form a V-shaped structure, and clamping faces are formed on the opposite sides of the upper arm and the lower arm respectively; the arrowhead-shaped component is arranged in a protruding mode from the end, away from the connecting part, of the upper arm to the lower arm, inverted teeth are arranged on the arrowhead-shaped component, and the bottom of the arrowhead-shaped component is a needle point; and the locking component is arranged on the lower arm, and when the upper arm and the lower arm are clamped, the arrow-shaped component penetrates into the locking component and locks the arrow-shaped component. In addition, the invention further relates to a clip applying instrument capable of clamping the puncture ligation clip. The ligature clip capable of puncturing is reliable in clamping, thick tissue can be punctured, and slipping and virtual clamping accidents can be avoided.
