Description

Endoscopic fixation kit

Technical Field

The invention belongs to the technical field of medical intervention equipment, and particularly relates to an endoscopic fixation kit.

Background

With the development of modern medical technology, the disease conditions of the etiology and focus situation can not be directly obtained, and the actual conditions of the corresponding parts in the patient can be accurately obtained by checking the patient with low influence or without influence through the existing medical equipment. The endoscopic retrograde cholangiopancreatography is a modern medical interventional treatment means, specifically, a duodenal mirror is inserted into a duodenal descending part to find a duodenal papilla, a contrast catheter is inserted into a papilla opening part through a biopsy pipeline, and an x-ray shooting sheet is used for displaying the cholangiopancreatography after the contrast agent is injected. Because ERCP does not need to be operated, the wound is small, the operation time is short, the complications are less than the surgical operation, the hospitalization time is also greatly shortened, and the method is welcomed by patients. ERCP has achieved tremendous clinical success in the short decades and has become an important treatment for pancreatic and biliary diseases today.

When ERCP operation, need to carry out incision expansion operation to partial tissue under the scope, after incision formation, corresponding position has bigger swing range, in order to be convenient for operate, then need adopt disposable closure clamp to carry out the centre gripping fixedly to prevent that the irregular swing of the tissue of partial excision from sheltering from the affected part in operation, influence the operation.

However, the existing closing clip, whether it is a common U-shaped titanium clip or a rotatable clip structure, can only release one piece in a single operation. If multi-point fixation is needed, the endoscope forceps are taken out and then are installed into the other endoscope forceps to be inserted into the affected part of the human body for operation, and the operation difficulty under the endoscope is high, and the difficulty of continuous fixation at intervals after single fixation is obviously higher than that of continuous release of two or more closure clips through single operation, so that a plurality of difficulties are caused.

Moreover, the tissue under the endoscope continuously swings all the time, even if the endoscope forceps can stretch and rotate to adjust the angle, the actual operation is difficult, and a single clip can only fix the tissue in a certain area. And because the volume of the closing clamp is smaller, when the incision or other parts are fixed, a plurality of closing clamps are required to be continuously fixed to achieve the expected effect, the correlation between the closing clamps is lower, and the connection and the fixation cannot be carried out.

Example 1:

The present embodiment discloses an endoscopic fixation kit, and the technical problems to be solved by the present embodiment need to be briefly described because of the structural differences from the prior art. Firstly, an endoscope is a pipeline structure which enters the human body through a natural duct of the human body or through an operation incision, and the end part of the endoscope is provided with a camera with lamplight, so that the condition of an internal tissue part can be checked through the camera. If necessary, a different instrument is inserted through the channel for operation.

The instrument comprises a pair of forceps comprising a plurality of forms, but each having an operating end 1 and a line 2, the forceps being arranged at the end of the line 2, and the operating end 1 having a stiff wire which is passed through the line 2 to be connected to the forceps at the end for operation.

The most basic endoscope clamp has two forms of opening and occluding, can be used for grabbing and releasing, clamps the target tissue in the grabbing process, keeps the clamping state all the time after occluding and is pulled out, thereby achieving the purpose of sampling. While release includes a variety of structures, in this embodiment primarily directed to closure clips.

The closure clip is usually a disposable structure made of titanium metal, has a large internal force, and can be kept in an expanded state continuously. But the closing clamp is provided with a locking structure, and the locking structure can be locked and fixed when the closing clamp is mutually meshed by applying force through an external structure, so that the effect of stable clamping is achieved.

The prior art closure clips generally include two types, a U-clip and a rotating clip-closed cylindrical clip, and the present embodiment is described primarily with respect to a U-clip.

As shown in fig. 1, the hand-held clip used in this embodiment has an operating portion on the outside, and the end of the operating portion is connected to the endoscope forceps via a line 2. Such a clamp is a common instrument, the line 2 shown in the figures being rectilinear in shape, but flexible rubber tubing may be modified as required to accommodate the progress of the intestine.

As can be seen in fig. 5 and 6, the entire endoscopic forceps end portion has two forceps arms 3, and the end portion of the forceps arms 3 has a relief groove 3.2 along the length of the forceps arms 3. The two clamp arms 3 are controlled to clamp by the operating end 1 through the connection of the cable in the pipeline 2 and the operating end 1. The clamp holder is the existing equipment, and can place a common U-shaped titanium clamp at the end part of the clamp holder, and the clamp holder is limited by the bulge of the titanium clamp and the groove at the end part of the clamp arm 3. Because the U-shaped titanium clamp has an outward expanding internal force, and the two ends are provided with locking buckling structures, the whole titanium clamp is limited to be kept in a locking state only when the U-shaped titanium clamp is completely buckled, and the titanium clamp is attached to the clamp arm 3 during operation.

In the prior art, as the endoscope forceps only have a group of grooves for clamping and limiting, only one titanium clamp can be installed in a single operation, and the endoscope forceps are pulled out and then installed after being released, thereby bringing inconvenience to the operation under the endoscope. Especially, the incision or other tissues with larger swing amplitude which need to be fixed quickly after one point is fixed, once the time is poor, other parts which need to be fixed are easy to be scattered or convolved, the inconvenience is brought to the subsequent fixation, and the quality of the fixing effect can also influence the subsequent other operations.

There are devices in the prior art that improve the way in which an endoscopic forceps is advanced for single access and multiple releases, which often have a relatively complex front structure and a storage chamber for placing a plurality of closure clips, and the corresponding closure clip structure is also adjustable. In the embodiment, the titanium clamp is only optimized, the existing endoscope clamp structure can be directly adopted, and the effect of single-time stretching and multiple-time releasing can be achieved.

Specifically, the fixing kit in this embodiment includes at least two closing clips, and only the specific structure of an adjacent group of closing clips is described in this embodiment, since only a good limit connection effect is required to be formed between adjacent closing clips.

Wherein, the back of the clamp arm 3 of the single closing clamp is provided with an outward bulge, and the inner side of the closing clamp is provided with a connecting groove, and the bulge of the adjacent closing clamp falls into the connecting groove to realize limit, and the bulge has larger expanding internal force. The inner closing clip always keeps a close state with the outer closing clip under the action of no external force, the internal force causes the connection between the bulge and the connecting groove to be more stable, and all the closing clips can be kept fixed when the endoscope forceps are moved in the operation process.

And in the two ends of each closing clip, one is provided with a hook groove, the other is provided with a wedge-shaped tip, when the endoscope forceps are clamped, the wedge-shaped tip can be pushed to be inserted into the hook groove, at the moment, the ends form a stable locking state, the corresponding outward expansion internal force is restrained, and the corresponding outward expansion internal force is disconnected from the fitting state of the adjacent closing clip on the outer side, so that the single release is finished, and the internal closing clip cannot be influenced.

It should be noted that, in this embodiment, the clamp is mainly described, but a similar structure of rotating clamping is also applicable, and through the front-rear structural design, after the first group of clamps are fixed, the clamping structure at the end part of the first group of clamps and the adjacent cylindrical clamps still maintain the clamping limiting effect. At this time, the moving end causes the clip which has been fixed to pull out the adjacent clip inside and to continue pulling the spool under the restriction of the rotating mechanism, and the latter clip rapidly expands outwards due to the two metal arms falling out of the pipeline 2, thereby losing the clamping and fixing effect with the end of the front clip.

It should also be noted that the device of the present embodiment may be used in a variety of endoscopic surgical procedures, and is not limited to gastrointestinal surgery.

Example 2:

the embodiment discloses an endoscopic fixation kit, which also adopts a U-shaped closing clip structure, and is different from the embodiment 1 above in that adjacent closing clips are in nested connection.

Specifically, as shown in fig. 7 to 9, a closing clip structure different from that of embodiment 1 is shown. Although multiple overlapping designs may be employed, only the outermost closure clips are different, while the inner closure clips are identical in construction, only the outermost and adjacent closure clips are described.

In this embodiment, the same endoscope forceps are used as in embodiment 1, and the operation mode and the clamping mode are the same, so that a part of the contents will not be described again.

The inner side in the figure is a first closing clip 4 and the outer side is a second closing clip 5. The outer side of the end of the second closing clip 5 has two outward flanges 5.1, while in fig. 2 it can be seen that the end of the jawarm 3 has a circular clamping groove 3.1 perpendicular to the length direction of the jawarm 3, which clamping groove 3.1 just allows the flanges 5.1 of the second closing clip 5 to fall into the effect of a limit fixation.

The back of the first closing clamp 4 at the inner side is provided with a caulking groove 4.1, and it can be seen that the width of the back of the first closing clamp 4 is larger than the width of the clamping surface of the second closing clamp 5, so that the clamping surface of the second closing clamp 5 can just fall into the caulking groove 4.1 at the back of the first closing clamp 4 to realize sleeving. The connection mode avoids the mutual influence between the inner and outer closing clamps, and after the inner side is released, the outer closing clamp can be continuously in fit connection with the clamp arm 3 of the endoscope clamp. Meanwhile, compared with the limit connection mode of the bulge and the clamping groove 3.1, the nested connection with larger area has higher stability, and the possibility of falling off in the operation process can be reduced.

Example 3:

The embodiment discloses an endoscopic fixation kit, unlike the two embodiments described above, since each closing clip has an independent structure, after the release fixation, only a small area of tissue can be clamped and fixed, and for some target tissues having a certain length and needing to be moved to other positions, a plurality of closing clips are usually adopted, but the effect often cannot meet the operation requirement.

For example, in performing bile duct ERCP, it is necessary to insert a contrast catheter from a biopsy tube into the nipple opening, and if a stone or other condition occurs in the interior, it is necessary to enlarge the tube, and an expansion device is necessary. However, the nipple opening is smaller, and the opening position displayed under the lens is continuously moved, so that the operation convenience is greatly influenced. In this case, it is necessary to cut a part of the nipple opening by an electric knife, and then to pull out and fix one side of the nipple opening. If only one closing clip is clamped, the identification cannot achieve the expected effect. Multiple closing clips can also affect operation such that multiple clips are present in a localized area.

This embodiment is optimized for embodiment 2 described above, with one tensioning wire 6 being provided between two adjacent clips. First, the tensioning wire 6 has an expansion end which is located at the bend of the inner first closing clip 4 and which is formed by passing through the bend through the outer second closing clip 5.

At this time, through predetermining certain stretch-draw line 6 length, then make two closure clips can keep certain interval, can be convenient for operating personnel to use and reach better fixed effect this moment.

As shown in the above process, only the first closing clip 4 is required to be clamped and fixed with a side wall of the cut nipple opening at this time, because the first closing clip 4 is locked and fixed, the tensioning line 6 required to move the endoscope forceps is straightened, at this time, the second closing clip 5 is continuously connected with the endoscope forceps due to the cooperation of the flange 5.1 and the clamping groove 3.1 and the larger expansion force of the second closing clip 5, and the first closing clip 4 is pulled to the corresponding position through the tensioning line 6.

At this time, when the operation end 1 of the endoscope forceps is operated to fix the second closing clip 5 to the intestinal wall, the second closing clip 5 continues to give a pulling force to the first closing clip 4 to that position by the pulling wire 6, and the wall of the incised papilla opening is fixed.

It should be noted that, in this embodiment, only two adjacent closing clips are described as an example, but a plurality of closing clips may be actually used, and the spacing between the tensioning lines 6 between each closing clip is set according to the requirement, so as to achieve the effect of multi-point fixing tensioning. Because of the nested structure, and the closure clip made of titanium metal has larger expansion force, the closure clip can be kept stable in the tensioning process.

Example 4:

this embodiment also discloses an endoscopic fixation kit, and is optimally defined on the basis of embodiment 3 above. In the above embodiment 3, only the fixing manner between the two closing clips is limited, and since some fixing objects in operation have large displacement resistance, the fixing objects cannot be pulled only by the tension line 6 between the two closing clips, and the closing clip originally fixed on the endoscope forceps is separated.

In this embodiment, the closure clip is made of a non-metallic material that is easily absorbed and digested, and has a lower expansion force than titanium. In this embodiment, the connection is made by means of a tensioning wire 6, but the tensioning wire 6 has only one expansion end, which is located in the innermost closing clip and is fixed. The other end of the tensioning wire 6 passes through each closing clip in turn and is connected with a special stay wire arranged in the pipeline 2 on the endoscope forceps, and the stay wire extends to the operation end 1 and forms an independent end part for operation.

In this case, the tensioning line 6 can pass freely through the closing clamps which are not released from the locking, so that the closing clamps adjacent to and associated with the first closing clamp are not affected when the first closing clamp is fastened.

In order to achieve the tensioning effect as well, the embodiment is provided with a clamping opening 7 at the bending part of the closing clamp except the innermost part, as shown in fig. 9 and 10, or is provided with a hollowed opening 8 with a size larger than the section of the tensioning line 6 directly on the clamping arm near the bending part, as shown in fig. 11 and 12.

When the closing clamp is clamped and fixed, the bending part of the closing clamp is pressed inwards, and the tensioning wire 6 which can pass through the clamping opening 7 or the engraving opening 8 freely originally is locked, so that the fixing effect is achieved.

The operation is specifically as follows, firstly, the innermost closing clip is fixed on the target tissue, at this time, the endoscope forceps are moved to the corresponding position, and the movement of the second closing clip is not affected since the guy wire 6 is always in a free state. Then, the second closing clamp is moved to a corresponding position, the hooking groove of the clamp arm at one side of the second closing clamp is hooked with tissue to form a pre-knot, then the tension wire 6 is pulled at the operation end 1, at the moment, the first fixed closing clamp can drive the tissue to move to the position, after the second closing clamp is moved to a required length, the second closing clamp is operated to be fixedly locked, so that a tensioning and dragging fixed target is completed, at the moment, if only two targets to be fixed are needed, no closing clamp is left on the endoscope clamp, the end clamping of the endoscope clamp can be operated again to cut off the redundant tension wire 6, and the rest tension wire 6 can be taken away along with the endoscope clamp.

It should be noted that, in this embodiment, the tensioning wire 6 and the closing clip are both made of medical materials, which will not affect the intestinal tract and the patient's body, and are digestible materials, so that they will be digested at a certain time.

The invention is not limited to the alternative embodiments described above, but any person may derive other various forms of products in the light of the present invention. The above detailed description should not be construed as limiting the scope of the invention, which is defined in the claims and the description may be used to interpret the claims.
