Description

Technical Field

[0001] The utility model relates to the technical field of harmony clamps, in particular to a harmony clamp which can be adjusted at multiple angles. Background Art

[0002] The Harmony Clip is mainly used to close surgical wounds and clamp intracavitary tissues during gastrointestinal endoscopic surgery. The snare is a device that uses a nylon rod to tighten a sliding knot previously tied with absorbable or synthetic thread to ligate blood vessels, polyps or other pipeline structures. It is easy to operate and has been used in a variety of gastrointestinal endoscopic abdominal surgeries. When removing gastrointestinal polyps, first use a gastroscope to find out the location of the polyp and then insert the snare and Harmony Clip through the gastroscopic catheter to remove the polyp and close the wound.

[0003] The snare and the harmony clip are two different medical devices. The snare needs to be inserted from the gastroscope catheter to remove the polyp, then the snare needs to be pulled out and the harmony clip needs to be inserted to close the wound. Since the gastroscope catheter moves, the position needs to be re-explored after the harmony clip is inserted, which prolongs the operation time. The patient will also feel more uncomfortable after inserting the medical device twice. Therefore, a device for operating the snare and the harmony clip at the same time is provided (see patent number: 202020593663.X for details), including a harmony clip, a snare, a sheath tube, and an operating handle; the harmony clip includes a clip body and a clip sheath; the clip body is Y-shaped, and the tail end is a round tube; the front section of the clip sheath is a cylinder, and the rear end is a round tube with a slightly smaller diameter. The harmony clip can be gathered in the clip sheath; the control line of the snare is the existing snare push guide wire, the front section of the control line has a raised small cylinder, which is connected to the round tube on the small cylindrical clip body; the snare is connected to the front end of the small cylinder in the front section of the control line and gathered in the small round tube of the clip body; the main body of the sheath is the existing interventional catheter, the front end is connected to the harmony clip, and the tail end is fixedly connected to the operating handle; the holding handle is a cylindrical head fixedly connected to the sheath, the middle cylinder of the holding handle is hollow and connected to the sheath, and the control line is fixedly connected to the operating rod from the sheath to the holding handle; the operating rod is a cylinder, which is placed inside the holding handle and slides, and the utility model can deliver the snare and the harmony clip in the gastroscope catheter.

[0004] However, the existing Harmony Clamp has a fixed opening angle and cannot fully adapt to various angles of wounds encountered in actual work. In many cases, simply adjusting the angle of the front end of the endoscope still cannot perfectly face the wound, thereby reducing the utilization rate. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-angle adjustable harmony clamp in order to solve the problem that the existing harmony clamp has a fixed opening angle and cannot fully adapt to various angles of wounds encountered in actual work. In many cases, simply adjusting the angle of the front end of the endoscope still cannot perfectly face the wound, thereby reducing the utilization rate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-angle adjustable harmony clamp, comprising a protective cover and an operating rod, wherein a gripping handle extending to the inside of the operating rod is provided on a side of the operating rod away from the protective cover, a movable pull rod extending to one side of the inside of the protective cover is provided on a side of the gripping handle close to the protective cover, a clamping cover is provided on a side of the operating rod away from the movable pull rod away from the protective cover, a clamping device is provided on a side of the clamping cover away from the movable pull rod, the clamping device comprises a clamping frame, and the number of the clamping frames is two groups. The two groups of clamping frames are provided with a slide groove inside the clamping cover, the end faces of the two groups of clamping frames away from the slide groove are provided with fixing holes, the two groups of fixing holes are provided with a limiting column on the side away from the clamping frame, the two groups of limiting columns are provided with a placement rack on the side away from the fixing holes, and multiple groups of limiting holes are provided inside the two groups of limiting columns, the clamping device is provided with a chuck on the side away from the clamping cover, the clamping cover is provided with an inclined port on the side close to the clamping frame, and the inclined port is inclined toward the lower left, and the end face of the pin shaft is provided with a torsion spring.

[0007] As a further solution of the utility model: a movable hole is arranged inside the protective cover, a through hole is arranged on a side of the movable hole adjacent to the clamping cover, and the movable pull rod is movably and rotatably connected to the protective cover through the mutual cooperation of the movable hole, the through hole and the clamping cover.

[0008] As a further solution of the utility model: the clamping device is located inside the clamping cover and is movably connected to the protective cover.

[0009] As a further solution of the utility model: the two groups of clamping frames are both movably connected to the clamping cover through a slide groove and a pin shaft, and the pin shaft is fixedly connected to the movable pull rod.

[0010] As a further solution of the utility model: the outer diameter of the limit screw is smaller than the connection distance between each group of limit holes.

[0011] As a further solution of the utility model: both groups of fixing holes are provided with limiting screws inside, and both groups of placement racks are movably connected to the clamping rack through limiting columns, limiting holes, fixing holes and limiting screws.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Through the provided clamping device, when the clamping frame is forced to move toward the inside of the clamping cover, the clamping cover itself will generate a reverse force on the two sets of clamping frames, so that the two sets of clamping frames can be moved toward the adjacent end faces along the slide groove with the pin shaft as the base point, and the included angle can be made smaller and smaller, and at the same time, they can be extended to the inside of the clamping cover. When the clamping frame extends out of the clamping cover, since the end face of the clamping cover is an inclined port, the distance that the clamping frame located at the top end of the inclined port extends outward can be made smaller than the range of the clamping frame at the bottom end of the inclined port extending outward (the end face of the pin shaft is provided with a torsion spring, and the torsion spring is the clamping frame extending from the clamping cover The frame can better generate outward elastic pressure, so that the extension range is larger and the outward flip angle is larger. At the same time, the flip angle of the lower clamping frame is greater than the flip angle of the upper clamping frame. Thus, the clamping angle between the two sets of clamping frames can be larger, which is convenient for operation on different lesion ends. The difference between this harmonious clamp and the traditional harmonious clamp is that the angle facing the lesion is different, which can fully adapt to the wound surface of various angles faced in actual work. In many cases, the front end angle of the endoscope can be adjusted to perfectly face the wound surface. The harmonious clamp itself has different angles, and the angle can be adjusted according to the lesion when facing different lesions.

[0014] 2. Through the set limit screws and limit columns, when the clamping length needs to be adjusted, the limit column can be manually pulled or pressed to make the inner side of the limit column produce an extrusion force on the damping pad outside the limit screw, causing it to deform under force and generate corresponding elastic potential energy, so that the different holes on the limit column can be moved to the outside of the limit screw in sequence. When it is moved to the appropriate position, the damping pad outside the limit screw recovers after being free from force, so that it can be adjusted under the action of external force, and it can only be achieved after the external force reaches a certain strength, thereby ensuring its stability during use;

[0015] 3. By setting the protective cover, the movable pull rod can rotate inside the protective cover and carry the chuck to rotate along the inside of the clamping cover, so that the position of the chuck can be directly adjusted by rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figures 1 to 4In the embodiment of the utility model, a multi-angle adjustable harmony clamp includes a protective cover 1 and an operating rod 2. A gripping handle 3 extending to the inside of the operating rod 2 is provided on the side of the operating rod 2 away from the protective cover 1. A movable pull rod 4 extending to one side of the inside of the protective cover 1 is provided on the side of the gripping handle 3 close to the protective cover 1. A clamping cover 5 is provided on the side of the operating rod 2 away from the movable pull rod 4 away from the protective cover 1. A clamping device 6 is provided on the side of the clamping cover 5 away from the movable pull rod 4. The clamping device 6 includes a clamping frame 601. The number of the clamping frames 601 is two groups. The two groups of clamping frames 601 are close to the clamping cover 5. A slide groove 602 is provided inside one side, and a fixing hole 603 is provided on the end surface of the two groups of clamping frames 601 away from the slide groove 602. A limiting column 604 is provided on the side of the two groups of fixing holes 603 away from the clamping frame 601. A placement rack 605 is provided on the side of the two groups of limiting columns 604 away from the fixing holes 603. Multiple groups of limiting holes 606 are provided inside the two groups of limiting columns 604. A chuck 7 is provided on the side of the clamping device 6 away from the clamping cover 5. An inclined port is provided on the side of the clamping cover 5 close to the clamping frame 601, and the inclined port is inclined toward the lower left. A torsion spring is provided on the end surface of the pin shaft.

[0024] Please refer to Figure 1 and 2 A movable hole is provided inside the protective cover 1, and a through hole is provided on one side of the movable hole adjacent to the clamping cover 5. The movable pull rod 4 is movably and rotatably connected to the protective cover 1 through the mutual cooperation of the movable hole, the through hole and the clamping cover 5.

[0025] Please refer to Figure 1 , 2 and 3, the clamping device 6 is located inside the clamping cover 5 and is movably connected to the protective cover 1.

[0026] Please refer to Figure 1 , 2 , 3 and 4, the two groups of clamping frames 601 are movably connected to the clamping cover 5 through the slide groove 602 and the pin shaft, the pin shaft is fixedly connected to the movable pull rod 4, when the clamping frame 601 is forced to move toward the inside of the clamping cover 5, it will be affected by the clamping cover 5 itself to generate a reverse force on the two groups of clamping frames 601, so that the two groups of clamping frames 601 can move toward the adjacent end faces along the slide groove 602 with the pin shaft as the base point, and make their included angle smaller and smaller, and at the same time extend to the inside of the clamping cover 5, and when the clamping frame 601 extends out of the clamping cover 5, since the end face of the clamping cover 5 is an inclined port, the distance that the clamping frame 601 located at the top end of the inclined port extends outward can be smaller than the range of the clamping frame 601 at the bottom end of the inclined port, so that it is convenient to operate on different lesion ends.

[0027] Please refer to Figure 3 and 4The outer diameter of the limiting screw 607 is smaller than the connection distance between each set of limiting holes 606. While limiting the limiting column 604, it can conveniently pass through the space between each set of limiting holes 606, making it easy to adjust the length of its clamping end, and is highly practical.

[0028] Please refer to Figure 3 and 4 , the interior of the two groups of fixing holes 603 are both provided with limiting screws 607, and the two groups of placement frames 605 are movably connected to the clamping frame 601 through the limiting columns 604 and the limiting screws 607, which have extended the use length of the clamping frame 601 and fixed it at the same time to increase the use diversity of the device. A damping pad is arranged on the outside of the limiting screw 607, and the damping pad is located on the inner side of the limiting column 604. When the length needs to be adjusted, the limiting column 604 can be manually pulled or pressed to make the inner side of the limiting column 604 produce an extrusion force on the damping pad outside the limiting screw 607, so that it is deformed under force and generates corresponding elastic potential energy, so that different hole positions on the limiting column 604 can be moved to the outside of the limiting screw 607 in turn. After moving to the appropriate position, the damping pad outside the limiting screw 607 recovers after being free from force, so that it can be adjusted under the action of external force, and it can only be achieved after the external force reaches a certain strength, thereby ensuring its stability during use.

[0029] The working principle of the utility model is: when in use, when the clamping frame 601 extends out of the clamping cover 5, since the end face of the clamping cover 5 is an inclined port, the distance that the clamping frame 601 located at the top end of the inclined port extends outward can be smaller than the range of the clamping frame 601 at the bottom end of the inclined port extending outward, so that it is convenient to operate on different lesion ends. The difference between this harmonious clamp and the traditional harmonious clamp is that the angle of opening facing the lesion is different, which can fully adapt to the wound surfaces of various angles faced in actual work. In many cases, the front end angle of the endoscope can be adjusted to perfectly face the wound surface, and the harmonious clamp itself has different angles, which can be used for different lesion ends. When changing, the angle can be adjusted according to the lesion, and when the clamping length needs to be adjusted, the limit column 604 can be manually pulled or pressed to make the inner side of the limit column 604 produce an extrusion force on the damping pad outside the limit screw 607, causing it to deform under the force and generate corresponding elastic potential energy, so that the different hole positions on the limit column 604 can be moved to the outside of the limit screw 607 in turn. After moving to the appropriate position, the damping pad outside the limit screw 607 recovers after being free from force, so that it can be adjusted under the action of external force, and it can only be achieved after the external force reaches a certain strength, thereby ensuring its stability during use.
