Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a hemostatic titanium clip with a releasing function. Background Art
[0002] With the continuous advancement of endoscopic minimally invasive technology, cutting-edge endoscopic treatments such as ESD, POEM and STER have been rapidly developed and matured in a short period of time. Titanium clips play a very important role in these treatments. Titanium clips can be used for polypectomy, ESD wound closure, ulcers with bleeding, Dieu l afoy disease bleeding and other aspects, but most of them are currently used for tissue closure and hemostasis. Similar to ulcers with bleeding in upper gastrointestinal bleeding, such as ulcer bleeding in the gastric angle and gastric antrum, if the area is not large, titanium clips can be used directly to close the wound, while ulcers with larger areas (exposed blood vessels) can be clamped on both sides of the bleeding focus to achieve the purpose of hemostasis. Most regular wounds can be closed with titanium clips to achieve the effect of simple interrupted sutures in surgical operations, but the existing titanium clips have the following defects in actual use by medical staff:
[0003] 1. Currently, the existing titanium clips are basically two-claw clamps with a V-shaped structure. For flat tissue wounds, the opening of the V-shaped two-claws of the titanium clip needs to be transported and controlled to be perpendicular to the wound to achieve a good clamping and hemostasis effect. However, after the existing titanium clips are transported into the body, the front end is not easy to be accurately adjusted to a vertical angle, so it is difficult to achieve the expected hemostasis effect, and it takes a long time to continuously adjust, resulting in low efficiency.
[0004] 2. The existing V-shaped titanium clips can be used to clamp and stop bleeding for tissue plane wounds, but for complex cross-shaped wounds, multiple titanium clips are needed to clamp and stop bleeding one by one. The operation is too complicated, the operation time is too long, and the efficiency is low.
[0005] Therefore, we propose a hemostatic titanium clip with a release function to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0029] See also Figure 1-5 As shown, the utility model provides a hemostatic titanium clip with a releasing function, comprising a cylindrical handle 1, a sleeve 2, a closing tube 3, a cross clamp 4 and an adjusting mechanism 5 for changing the opening and closing state of the cross clamp 4. The handle 1, the sleeve 2 and the closing tube 3 are fixedly connected in sequence, the cross clamp 4 is slidably installed inside the closing tube 3, and the adjusting mechanism 5 is installed inside the handle 1, the sleeve 2 and the closing tube 3.
[0030] Specific as Figure 4 As shown, the cross-flap 4 includes four elastic flap claws 41 evenly distributed at different angles. The elastic flap claws 41 are bent, and the four elastic flap claws 41 are integrally connected at their roots. The elastic flap claws 41 have elastic deformation characteristics near the root, so that when there is no external force, the four elastic flap claws open to an open shape under the action of elastic deformation. The front ends of the elastic flap claws 41 are set as sharp teeth. The setting of the cross-flap 4 allows the operator to quickly grab the tissue around the wound and stop bleeding without identifying the direction of the wound. Compared with the traditional V-shaped flap, the present device is better able to clamp and stop bleeding on cross-shaped tissue wounds, and the hemostasis effect can be achieved without too many clamps. The clamps of the present device are more adaptable to wounds in different conditions in the body. For the hemostasis operation of complex wounds, the operation is greatly simplified, and the surgical efficiency can be effectively improved.
[0031] like Figure 2 and Figure 3 As shown, the adjustment mechanism 5 includes a slide groove 51 opened in the middle position of the side wall of the handle 1, a slide plate 52 slidably installed inside the slide groove 51, and a push rod 53 with one end fixedly connected to the end face of the slide plate 52. The end of the push rod 53 away from the slide plate 52 passes through the handle 1, the sleeve 2 and the end wall of the closing tube 3 in sequence and is fixed to the root end face of the cross clamp 4. The specific slide groove 51 is a through groove that passes through the side wall of the handle 1, and the slide groove 51 extends along the axial direction of the handle 1, so that the slide plate 52 can only slide along the axial direction of the handle 1. The slide grooves 51 extend radially along the handle 1 on both sides of the slide plate 52, which is convenient for the operator to grasp and control. Preferably, a ring 55 fixed to the slide plate 52 can be slidably connected to the handle 1. The ring 55 can make the operation more convenient for the operator. The two ends of the push rod 53 are respectively fixed to the end face of the slide plate 52 and the cross clamp 4. When the operator slides the slide plate 52, the push rod 53 drives the cross clamp 4 to slide in the closing tube 3. When sliding out of the closing tube 3, the front end of the cross clamp 4 opens. At this time, the staff can move it to the wound. When sliding into the closing tube 3, the front end of the cross clamp 4 contracts to clamp the wound to stop bleeding.
[0032] As a preferred technical solution of the utility model: a detachable structure 54 is arranged between the push rod 53 and the cross clamp 4, and the detachable structure 54 includes a plurality of elastic clips 541 fixed on the end face of the push rod 53 and distributed along its circumferential direction. There are at least three elastic clips 541, and the three elastic clips 541 are in a truncated cone structure, that is, the outer diameter of the end of the elastic clip 541 away from the push rod 53 gradually decreases, and a sleeve hole 542 is provided on the outer wall of the root of the cross clamp 4, and the side walls of the plurality of elastic clips 541 are all provided with annular grooves 543 adapted to the sleeve hole 542. The cross clamp 4 can be clamped in the annular groove 543 through the sleeve hole 542, and the clamping arrangement of the cross clamp 4 and the elastic clip 541 can facilitate the disassembly of the elastic clip 541 for cleaning and maintenance.
[0033] As a preferred technical solution of the utility model: it also includes a limiting mechanism, which includes a limiting pawl 61 and a guide rib 62 arranged on the outer wall of the elastic clamping claw 41, and a pawl retaining groove 63 and a guide groove 64 respectively adapted to the limiting pawl 61 and the guide rib 62 are opened inside the closing tube 3. Figure 3 and Figure 4 As shown, the limiting pawl 61 is located on the side of the guide rib 62 close to the root of the cross-clamp flap 4. The limiting pawl 61 is a triangular shaped protrusion with the front end protruding toward the claw tip of the elastic clamp flap claw 41. The pawl retaining groove 63 is an arc-shaped groove. The limiting pawl 61 is clamped in the pawl retaining groove 63 when the cross-clamp flap 4 slides into the closing tube 3. The guide groove 64 is a blind groove opened on the inner wall of the closing tube 3 along the axial direction of the closing tube 3. The outer side of the elastic clamp flap claw 41 of the guide rib 62 is arched. The setting of the guide rib 62 plays a role in reinforcing the elastic clamp flap claw 41 to avoid the elastic clamp flap claw 41 from being reversely bent or broken. Secondly, it cooperates with the guide groove 64 in the closing sleeve 3 to guide the cross-clamp flap 4 when it is pushed and pulled in the closing sleeve.
[0034] As a preferred technical solution of the utility model: the inner walls of the claw tips of the four elastic clamping claws 41 are all provided with hooking claws 42, and the hooking claws 42 are triangular structures protruding toward the roots of the elastic clamping claws 41 at the rear end. When the sharp teeth grab the tissue, the hooking claws 42 can firmly grasp the tissue to prevent it from falling off, thereby better fixing the wound.
[0035] As a preferred technical solution of the present invention: a pull ring 8 is provided at one end of the handle 1 away from the sleeve 2, and the pull ring 8 is provided to facilitate the staff to hold it.
[0036] How it works
[0037] After the installation of the device is completed, the elastic clamping claw 41 of the cross clamping flap 4 is completely retracted in the closing sleeve 3. At this time, the limit ratchet 61 on the elastic clamping claw 41 is in the front position of the ratchet stop groove 63 of the closing sleeve 3, and the elastic clamping claw 41 is completely retracted in the closing sleeve 3. When the patient needs to stop bleeding, the operator pushes the device to the tissue of the patient that needs to stop bleeding, pushes the ring 55, and the cross clamping flap 4 slowly moves out of the closing sleeve, and the elastic clamping claw 41 slowly opens from the contracted state. After the cross clamping flap 4 is completely moved out of the closing sleeve, the elastic clamping claw 41 of the cross clamping flap 4 is in a fully opened state. At this time, the operator aligns the claw tip of the cross clamping flap 4 with the patient's tissue, pulls the ring 55, and the sharp teeth of the elastic clamping claw 41 will slowly clamp the tissue that needs to stop bleeding, which plays a role in stopping bleeding. At the same time, the hooking ratchet 42 mechanism at the front end of the elastic clamping claw 41 further fixes the tissue to prevent the tissue from falling off during this process. The cross-clamp petal 4 to be clamped slowly enters the closing sleeve 3, and the elastic clamp petal claw 41 also slowly contracts and finally enters the closing sleeve 3. The collar 55 makes the elastic clamp petal claw completely contracted in the closing tube, and at the same time makes the limiting ratchet 61 on the rear section of the elastic clamp petal claw 41 enter the ratchet stop groove 63 of the closing tube 3. At this time, the cross-clamp petal 4 is completely fixed and will not move out of the closing sleeve 3, so that the elastic clamp petal claw 41 is firmly fixed.
