Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a multi-sequence tissue clip, which can solve the problem that in the existing minimally invasive surgery, only a single tissue clip can be used for tissue hemostasis operation, and can be inserted into the forceps channel at one time for multi-position wound clamping. Hemostasis, which greatly simplifies the operation process, and one-time plugging solves the problems of low efficiency of hemostasis surgery, reduced clamp channel life, and increased equipment cost

Embodiment Construction

[0031] Below in conjunction with each accompanying drawing, the present invention is described in detail.

[0032] to combine figure 1 and figure 2 , the multi-running tissue clip includes a housing 1, a slip ring 2, a flexible tube 3, a clamping mechanism and a joystick 4, preferably the housing 1 includes a core rod 11, a nut 12, a sheath tube 13 and an outer Tube 14. The assembly feature of the shell 1 is: the core rod 11 and the sheath tube 13 are connected by a nut 12 , and the outer tube 14 is welded on the inner wall of the sheath tube 13 . The slip ring 2 is slidably connected to the core rod 11, and the joystick 4 is fixed on the slip ring 2. One end of the outer pipe 14 is connected with a flexible pipe 3 through a reducing joint 141. Preferably, the flexible pipe 3 is spring tube. Preferably, the joystick 4 includes a steel wire rod, a booster tube and a positioning tube (not shown in the figure), and one end of the steel wire rod is connected with a booster tu...

Abstract

The invention relates to the technical field of minimally invasive surgical instruments and particularly relates to a multi-shooting tissue clamp. The tissue clamp comprises a shell, sliding ring, a flexible pipe, at least two clamping mechanisms and an operation rod, wherein the sliding ring is connected with the shell in a sliding manner; the flexible pipe is fixed at one end of the shell and iscommunicated with the shell; the clamping mechanism is mounted in the flexible pipe and can be pushed out of the flexible pipe; two ends of the operation rod are respectively connected with the clamping mechanisms and the sliding ring; and at least two clamping mechanisms are distributed along the axial direction of the flexible pipe, the sliding ring slides to push the clamping mechanisms out ofthe flexible pipe through the operation rod, and when a tissue is clamped by virtue of the clamping mechanism located outside the flexible pipe, the operation rod is pulled to be separated from the clamping mechanism and is connected with the next clamping mechanism, and the next clamping mechanism can be pushed by the operation rod and can be used for separating the last clamping mechanism fromthe flexible pipe. According to the technical scheme, the surgical operation process is greatly simplified, the efficiency of a hemostasis surgery is effectively improved, the plugging number of timesduring the single surgery is reduced, the service life of a pincers channel is prolonged, and the equipment cost is lowered.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgical instruments, in particular to a multi-sequence tissue clip. Background technique [0002] Tissue clips, also known as hemostatic clips, are often used for hemostasis of wounds in minimally invasive surgery. Existing tissue clips generally have a single-shot structure with a single clamping mechanism. Therefore, when multiple hemostasis operations are required when multiple hemostatic operations are encountered, it is necessary to use a tissue clip in the clamp channel to perform hemostasis operations. Remove the tissue clips and place new ones in the channel for a second operation. Such an operation is very cumbersome for the operator. Inserting and pulling out the tissue clip multiple times not only reduces the operation efficiency, but also significantly reduces the service life of the clamp channel and increases the equipment cost. Contents of the invention [0003] The ...
