AI Technical Summary
The existing clamp applicators with continuous clamping are prone to mechanism jamming and clamping failure during use. The main reason is that the clamping arm of the ligation clamp protrudes in the same direction, resulting in the ligation clamp stored in the clamping chamber closing. The tail is tilted toward the side wall of the clamp cartridge, and the head of the push clamp is difficult to resist the clamp waiting to be entered to close the tail to complete the clamp feeding.
A clamping device is designed, and the side wall of the clamping chamber is provided with a convex tilt platform in the clamping chamber, including a guide part and a clamping part arranged in sequence from near to far, and the acting position is close to the middle of the left and right directions of the clamping chamber, and guides the The portion extends in the far and near direction and can abut with its second clamp arm during the clamping process of the clamping of the clamping to be entered, ensuring that the head of the push clip is stable against the closed tail of the clamping to be entered.
Through the design of the working position and the guide part of the tilt table, the head of the push clamp can be stably resisted by the closed tail of the clamp to be entered, reducing the clamp stuck and improving the stability of the clamp.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a clip magazine device and a clip applier. Background Art
[0002] In order to fully expose the surgical field during surgery, it is necessary to ligate the blood vessels around the target tissue to stop bleeding. Hemostasis technology has become one of the core basic surgical operation techniques. Surgical operations on any part of the human body almost without exception involve bleeding and hemostasis. Generally, a clip applier ligation clip is used to close the hemostasis.
[0003] In order to improve the efficiency of surgery, a clip applier capable of continuously delivering clips has emerged. The clip compartment of the clip applier capable of continuously delivering clips stores multiple ligature clips. After the clip applier completes the firing of a ligature clip to close the clip, the next ligature clip can be immediately delivered to the jaws for the next firing, thus realizing the continuous firing of the ligature clips by the clip applier.
[0004] The ligation clips of the continuous clip appliers currently used on the market are as follows: Figure 1 As shown, the clamping device is as follows Figures 2 to 4 The ligation clamp comprises a first clamp arm 11 and a second clamp arm 12 connected to each other, one end of the two clamp arms is connected to form a closed tail of the ligation clamp, and the other end is a free end, the free ends of the two clamp arms are far away from each other to form a V-shape, the first clamp arm 11 is an arc convex to the outside of the V-shape, and the second clamp arm 12 is an arc convex to the inside of the V-shape, the free end of the first clamp arm 11 is provided with a locking hook 111 bent inwardly, and the free end of the second clamp arm 12 is provided with a hook groove 121 matched with the locking hook 111, and the locking hook 111 and the hook groove 121 cooperate with each other to realize the closure of the ligation clamp. In order to facilitate the jaws 9 of the clamp applier to clamp the ligation clip, a first clamping column 21 is arranged at a position of the first clamp arm 11 close to the locking hook 111 (that is, close to the free end), and the height direction of the first clamping column 21 is perpendicular to the side plane of the V-shaped ligation clip body, and two first clamping columns 21 are arranged symmetrically on both sides of the first clamp arm 11; a second clamping column 22 is arranged at a position of the second clamp arm 12 close to the hook groove 121 (that is, close to the free end), and the height direction of the second clamping column 22 is perpendicular to the side plane of the V-shaped ligation clip body, and two second clamping columns 22 are arranged symmetrically on both sides of the second clamp arm 12.
[0005] The clamping device includes a clamping chamber 3 for accommodating a plurality of ligation clips and a clamp pushing piece 4 for pushing the ligation clips. The plurality of ligation clips include a ligation clip 13 to be inserted into the clamp (a ligation clip to be inserted into the jaw 9) located at the farthest end of the clamping chamber 3 and ligation clips arranged and stored near the ligation clip 13 to be inserted into the clamp. The openings of the plurality of ligation clips are placed flat on the bottom plate of the clamping chamber 3 in sequence in the direction of clip feeding, the first clamp arm 11 of the ligation clip is in contact with the first side wall of the clamping chamber 3, and the second clamp arm 12 of the ligation clip is in contact with the second side wall of the clamping chamber 3. A plurality of first elastic clamping positions 311 that are tilted upward along the direction of clip feeding are arranged at equal intervals on the bottom plate 31 of the clamping chamber. The push clamp 4 includes a push clamp body 41 and a push clamp head 42 connected in sequence. The push clamp head 42 is bent to one side relative to the push clamp body 41. The push clamp body 41 covers the top of the ligation clamp except the ligation clamp 13 of the forceps to be inserted. The push clamp head 42 extends into the clamp compartment 3 and is arranged close to the ligation clamp 13 of the forceps to be inserted. A plurality of second elastic clamping positions 411 that are evenly spaced along the clamp feeding direction and tilted downward are arranged on the push clamp body 41.
[0006] Before the continuous clip applier delivers the clips, the first elastic clamping position 311 at the farthest end of the ligation clip 13 to be inserted is closer to the far end of the clip compartment 3, the clamping posts of the ligation clips other than the ligation clip 13 to be inserted are located between two adjacent first elastic clamping positions 311, and the second elastic clamping position 411 is located between the clamping posts of the adjacent ligation clips other than the ligation clip 13 to be inserted. When the continuous clip applier delivers the clips, the push clip piece 4 moves forward toward the far end of the clip compartment 3, the raised portion of the second elastic clamping position 411 gradually abuts against the first clamping post 21 and / or the second clamping post 22 of all the ligation clips other than the ligation clip 13 to be inserted, and at the same time, the head portion 42 of the push clip piece abuts against the tail of the ligation clip 13 to be inserted. As the clamp pusher 4 continues to move toward the far end of the clamp bin 3, it pushes all the ligation clips toward the far end of the clamp bin 3 until the ligation clip 13 to be inserted enters the jaws 9, and the clamp pusher 4 stops moving toward the far end of the clamp bin 3. In this process, all the ligation clips except the ligation clip 13 to be inserted will pass over the first elastic clamping position 311 adjacent to the far side. Then the clamp pusher 4 moves toward the proximal end of the clamp bin 3, and the clamp pusher head 42 and the second elastic card drive all the ligation clips except the ligation clip 13 to be inserted to move toward the proximal end of the clamp bin 3. When all the ligation clips except the ligation clip 13 to be inserted contact the first elastic clamping position 311, the first elastic clamping position 311 blocks all the ligation clips except the ligation clip 13 to be inserted from moving toward the proximal end of the clamp bin 3. Since the clamp pusher head 42 and the second elastic sheet are elastic, the clamp pusher head 42 and the second elastic sheet will pass over the proximal adjacent ligation clip, and then the clamp pusher 4 stops moving toward the proximal end of the clamp bin 3. The clamp pusher 4 reciprocates in this way, and the ligation clamps are delivered to the jaws 9 one by one.
[0007] The above-mentioned continuous clip applier may experience problems such as stuck mechanism and clip delivery failure during use. The main reason is that since the two clamp arms of the ligation clamp are arc-shaped and protrude in the same direction, the closed tail of the ligation clamp stored in the clamp compartment 3 tends to be biased toward one side wall of the clamp compartment 3 (such as Figure 3 As shown, in Figure 3 In the process of delivering the ligation clip 13 to the jaws 9, it is not conducive to the push clip head 42 to press against the closed tail of the ligation clip 13 to complete the delivery of the clip, causing the delivery of the clip to fail.
[0008] For this reason, an improved clip cartridge device and clip applier are badly needed. Utility Model Content
