Description

Technical Field

[0001] The utility model relates to the technical field of clip applicators, in particular to a pushing device of a bendable clip applicator. Background Art

[0002] The clip applier is used to clamp the titanium clip on human tissue to stop bleeding or close the patient's tissue. Traditional clip appliers, such as the flat-mouthed clip applier disclosed in the utility model patent with application number 201921062505.5 and the medical scissors-like clip applier disclosed in the utility model patent with application number 201922053668.3, can both clamp the titanium clip on human tissue.

[0003] However, it was found during use that the existing clamp applicator has a relatively simple structure and is not convenient for adjusting the angle of the clamp head in the human body. The doctor needs to repeatedly adjust the position of the clamp applicator or expand the minimally invasive opening, resulting in poor practicality. Therefore, a pushing device for a flexible clamp applicator is urgently needed to improve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a pushing device for a flexible clamp, which places a titanium clip in a clamping mechanism, then extends the clamping mechanism into the patient's body, and then adjusts the bending angle of the clamping mechanism through a power mechanism cooperating with a pushing mechanism, and then closes the clamping mechanism by gripping the holding mechanism to clamp the titanium clip on the tissue in the patient's body, thereby improving the practicality of the device.

[0005] The utility model discloses a pushing device of a flexible clamp applicator, comprising a holding mechanism, a power mechanism, a pushing mechanism and a clamping mechanism, wherein the power mechanism, the pushing mechanism and the clamping mechanism are all installed on the holding mechanism;

[0006] The holding mechanism provides power for the clamping mechanism, the power mechanism cooperates with the pushing mechanism to adjust the bending angle of the clamping mechanism, and the clamping mechanism clamps the titanium clamp;

[0007] The titanium clip is placed in the clamping mechanism, and then the clamping mechanism is extended into the patient's body. The bending angle of the clamping mechanism is adjusted by the power mechanism and the pushing mechanism. Then, the clamping mechanism is closed by gripping the holding mechanism to clamp the titanium clip on the tissue in the patient's body, thereby improving the practicality of the device.

[0008] Preferably, the holding mechanism includes a holding handle, a supporting outer tube and a pull rod, the power mechanism is installed on the holding handle, the supporting outer tube is installed on the power mechanism, one end of the pull rod is installed on the holding handle, the other end of the pull rod is installed on the clamping mechanism, and the pull rod is located inside the supporting outer tube; by loosening the holding handle and transmitting the pull rod, the clamping mechanism is opened, which makes it convenient for the doctor to place the titanium clip in the clamping mechanism; by tightening the holding handle and transmitting the pull rod, the clamping mechanism is closed and the titanium clip is clamped on the patient's tissue, thereby improving the practicability of the device.

[0009] Preferably, the power mechanism includes a rotating wheel, a rotating sleeve, a sliding shaft and a locking mechanism. An opening is provided on the right portion of the supporting outer tube. The rotating wheel is rotatably mounted on the holding handle, the rotating sleeve is mounted inside the rotating wheel, the sliding shaft is mounted on the pushing mechanism, and one end of the sliding shaft passes through the opening of the supporting outer tube and is threadedly connected to the inner wall of the rotating sleeve, and the locking mechanism is mounted on the supporting outer tube. The rotating sleeve is rotated by rotating the rotating wheel, and at the same time, the sliding shaft is guided through the opening of the supporting outer tube, so that the sliding shaft moves laterally inside the supporting outer tube, thereby driving the pushing mechanism to move laterally, thereby improving the practicability of the equipment.

[0010] Preferably, the locking mechanism includes a rotating handle and a screw, and the rotating handle is installed on the supporting outer tube through the screw thread; by rotating the rotating handle, the screw squeezes the pushing mechanism to limit the pushing mechanism, thereby improving the stability of the equipment.

[0011] Preferably, the pushing mechanism includes a pull tube and a push-pull plate, both of which are installed inside the supporting outer tube, and the right part of the push-pull plate is connected to the other end of the sliding shaft. One end of the pull tube is installed on the push-pull plate, and the other end of the pull tube is installed on the locking mechanism; the pull tube moves horizontally inside the supporting outer tube and is then transmitted through the push-pull plate to make the clamping mechanism bend, thereby improving the practicability of the equipment.

[0012] Preferably, the clamping mechanism includes a clamp head and a rotating shaft, and the clamp head is rotatably mounted on the supporting outer tube via the rotating shaft; the titanium clamp is placed in the clamp head, and is laterally moved inside the supporting outer tube via a push-pull plate, and then the clamp head is rotated around the rotating shaft via a pull tube, and the clamp angle is adjusted, and then the clamp head is closed by gripping the gripping handle, and the titanium clamp is clamped on the patient's tissue, thereby improving the practicability of the device.

[0013] Preferably, the surface of the rotating wheel is provided with anti-slip grooves, which makes it convenient for doctors to rotate the rotating wheel, thereby improving the practicability of the equipment.
