At present, the esophageal stent is widely applied to medical problems of esophageal stenosis, esophageal-tracheal fistula and the like caused by various reasons in clinic, and for most cases, the stent needs to be arranged to be taken out to achieve the purpose of treatment when the stenosis is relieved, the fistula is healed or the next measure is taken. However, because the stent graft can not be firmly fixed on the esophagus for a long time, especially for benign patients, when the disease is relieved and the esophageal stenosis is eliminated, the stent graft is easy to shift and even fall into the gastric cavity and the intestinal cavity, thereby affecting the treatment effect of the stent graft, and even causing serious complications such as intestinal obstruction, intestinal perforation and the like. Therefore, the stent is generally left with an extracorporeal recovery thread, which is pulled through the mouth or nose to prevent the stent from shifting or falling. The stent is taken out until the esophageal stenosis of a patient is relieved or the fistula is healed, and the placing period is generally 1 to 2 months; clinically, the extracorporeal recovery thread is generally fixed to the nasal alar, cheek and ear of a patient by using adhesive tape to achieve the purpose of fixation. However, this approach presents the following problems: because the in vitro recovery line is directly led out from the nasal cavity of the patient and keeps certain tension, and the tension is not easy to adjust, the patient has throat discomfort, the skin around the nose wing and the ears is damaged, the pain is obvious, the patient can eat more obviously, the discomfort is increased, and the life quality is reduced.

Based on the above problem, the present invention provides a fixing device 100, please refer to fig. 1-4, fig. 1 and 2 show the structure of the fixing device in the embodiment of the present invention, and fig. 2 and 3 show the structures of the first connecting member and the second connecting member in the embodiment of the present invention; the fixing device 100 includes an adhesive member 110, a first connecting member 120 and a second connecting member 130.

Wherein the first connector 120 is connected to the adhesive member 110, the second connector 130 is used for connecting to the proximal end of the extracorporeal recovery wire 140, and the first connector 120 is detachably connected to the second connector 130.

The working principle of the fixing device 100 is as follows:

the pasting member 110 of the fixing device 100 is pasted on the face or neck of the user, when the proximal end of the external recovery wire 140 is connected with the second connecting member 130, the proximal end of the external recovery wire 140 can be fixed on the face or neck of the patient through the matching of the first connecting member 120 and the second connecting member 130, and the connection mode of the first connecting member 120 and the second connecting member 130 is detachable connection, so that the tension of the external recovery wire 140 can be adjusted by adjusting the connection state of the first connecting member 120 and the second connecting member 130, thereby reducing the uncomfortable feeling of the user and being beneficial to improving the life quality of the user.

It should be noted that, in this embodiment, the user using the fixing device 100 is the patient using the esophageal stent described above. Furthermore, the terms "distal" and "proximal" are used throughout the specification, and are described herein for the purpose of better understanding only, and are not to be construed as limiting the present invention. Generally, during use of the fixing device 100, a front end portion of the extracorporeal recovery wire 140 (referred to as a left end of the extracorporeal recovery wire 140 in a relative position in fig. 2) extends into the human body, and a rear end portion of the extracorporeal recovery wire 140 (referred to as a right end of the extracorporeal recovery wire 140 in a relative position in fig. 2) is provided for operation by the medical staff. Thus, "distal" may be understood as a part or component that is relatively close to the anterior portion of the body, and "proximal" may be understood as a part or component that is relatively close to the posterior portion of the body. Of course, when it is not explicitly indicated which part or component is "proximal" or "distal", the default designation is the proximal or distal end of the entire extracorporeal recovery line 140.

Based on the above, in the using process of the fixing device 100, the tension of the extracorporeal recovery line 140 can be adjusted by changing the connection state of the first connecting piece 120 and the second connecting piece 130, so as to reduce the discomfort of the user, that is, in the using process, the tension of the extracorporeal recovery line 140 can be maintained by the connection of the first connecting piece 120 and the second connecting piece 130; the tension can be released by detaching the first connecting piece 120 and the second connecting piece 130, so that the stress between the external recovery line 140 and the contact part of the user is reduced, the contact pressure to the user can be reduced, the discomfort of the user is reduced, and the life quality of the user is improved. Therefore, the user can adjust the connection state of the first connecting piece 120 and the second connecting piece 130 according to the use feeling during the use process; in this embodiment, in order to adjust the connection state between the first connecting element 120 and the second connecting element, a clamping connection is adopted between the first connecting element 120 and the second connecting element 130, and in other embodiments of the present invention, other types of detachable connection may also be adopted between the first connecting element 120 and the second connecting element 130. For example, plug connection, screw connection, etc.

To realize the above-mentioned clamping connection between the first connector 120 and the second connector 130, referring to fig. 1-4, in the present embodiment, when the first connector 120 is disposed, the first connector 120 includes a connection post 121 and a clamping groove 122 disposed on an outer peripheral surface of the connection post 121. When the second connector 130 is provided, the second connector 130 includes a mounting plate 131 and a snap ring 133 connected to the mounting plate 131; wherein, the bottom surface of the mounting plate 131 is provided with a through hole. After the connection post 121 of the first connector 120 passes through the through hole, the connection post 121 passes through the clamping groove 122 on the outer circumferential surface of the through hole part and is clamped with the clamping ring 133, so that the mounting disc 131 is clamped with the first connector 120.

In the process of the joint of the first connecting piece 120 and the second connecting piece 130, the clamping groove 122 on the connecting column 121 and the clamping ring 133 on the mounting disc 131 are clamped, and when the first connecting piece 120 and the second connecting piece 130 need to be detached, the clamping ring 133 and the clamping groove 122 are disengaged by external force, so that the first connecting piece 120 and the second connecting piece 130 can be disengaged.

It should be noted that the structure of the first connecting member 120 and the second connecting member 130 is only one of various clamping manners, and in other embodiments of the present invention, other types of male and female buckle clamping manners can be selected.

Further, in this embodiment, in order to facilitate the connection between the proximal end of the extracorporeal recovery wire 140 and the second connecting member 130, the second connecting member 130 further includes a rotating bracket 132, the rotating bracket 132 is rotatably connected to the mounting plate 131, and the proximal end of the extracorporeal recovery wire 140 is wound around the rotating bracket 132. In this way, first, the length of the extracorporeal recovery wire 140 can be adjusted by adjusting the number of turns of the extracorporeal recovery wire 140 wound around the rotating bracket 132, thereby adjusting the tension of the extracorporeal recovery wire 140; secondly, since the rotating bracket 132 is rotatably connected to the mounting plate 131, the rotating bracket 132 can be rotated to drive the extracorporeal recovery line 140 to change the position relative to the first connecting member 120, that is, the length of the extracorporeal recovery line 140 can be adjusted, so as to adjust the tension of the extracorporeal recovery line 140. It should be noted that, when the length of the extracorporeal recovery wire 140 is adjusted, the extracorporeal recovery wire 140 may be wound around the first connecting member 120, and the principle is that, since the first connecting member 120 is connected to the adhesive member 110, the extracorporeal recovery wire 140 is fixed with respect to the adhesive member 110 by winding the extracorporeal recovery wire 140 around the first connecting member 120, so that the length of the extracorporeal recovery wire 140 can be prevented from being changed by the reaction force of the tension; in addition, the first connector 120 includes a connection column 121 and a locking groove 122 disposed on the outer circumferential surface of the connection column 121, so that when the extracorporeal recovery wire 140 is wound around the first connector 120, the extracorporeal recovery wire 140 is wound around the outer circumferential surface of the connection column 121 or wound around the locking groove 122.

In order to limit the rotation angle and rotation state of the rotating bracket 132 during the rotation process, so as to avoid the position of the rotating bracket 132 from changing during the use process, in the present embodiment, a limiting portion (not shown in the form of drawings) is provided on the mounting plate 131, and the limiting portion is used to connect with the rotating bracket 132 to limit the rotation of the rotating bracket 132 relative to the mounting plate 131. It should be noted that, when the limiting portion is provided, the limiting portion may be a structure that is arranged on the mounting disk 131 and is engaged with the rotating bracket, and the setting position of the limiting portion may be a position where the rotating bracket 132 is rotatably connected with the mounting disk 131.

In the embodiment, in order to improve the effect of limiting the rotation of the rotating bracket 132, the rotating connection position of the rotating bracket 132 on the mounting plate 131 is spaced from the limiting portion, so that the rotating torque formed by the limiting portion to limit the rotation of the rotating bracket 132 relative to the mounting plate 131 is increased, thereby avoiding the situation of failure of limiting.

In this embodiment, the installed esophageal stent cannot be firmly fixed on the esophagus for a long time, and particularly for benign patients, when the disease is relieved and the esophageal stenosis is eliminated, the stent is easy to shift and even fall into the gastric cavity and the intestinal cavity, so that the treatment effect of the stent is affected, and serious complications such as intestinal obstruction and intestinal perforation occur. Therefore, the stent is generally left with an extracorporeal recovery thread, which is pulled through the mouth or nose to prevent the stent from shifting or falling. The stent is taken out until the esophageal stenosis of the patient is relieved or the fistula is healed. The placing period of the bracket is 1-2 months; therefore, when the adhesive member 110 is disposed, referring to fig. 3, the adhesive member 110 can be a gelatin patch 111, because the gelatin patch 111 can be washed with water, can be reused, can be replaced, has strong adhesive force, good biocompatibility of materials, does not irritate skin, and is suitable for long-term wearing.

Furthermore, the first connecting member 120 can be detachably connected to the adhesive member 110, so that the gelatin sticker 111 can be easily replaced or cleaned, and the gelatin sticker 111 has a re-cleaning function, and can be removed and cleaned with clean water, so that the previous function can be recovered, and the service life of the fixing device 100 can be prolonged.

Further, in the present embodiment, the gelatin patch 111 is attached to the face or the neck of the user, and in order to improve the comfort of use, the gelatin patch 111 has a shape adapted to the neck of the patient or the face of the patient, so that the gelatin patch 111 can be attached to the face or the neck of the user, thereby reducing the discomfort of the patient caused by the attachment 110.

Referring to fig. 5-8 in conjunction with fig. 3, fig. 3 shows a polygonal gelatin patch in an embodiment of the present invention, and fig. 5-8 respectively show a circular arc shape, a water drop shape, a gourd shape and a butterfly shape gelatin patch in an embodiment of the present invention; specifically, in the embodiment of the present invention, in the process of setting the gelatin sticker 111, the gelatin sticker can be set to be polygonal, arc, drop, gourd or butterfly shape, so as to ensure the stability of sticking and prevent the accidental falling. It should be noted that the above shapes are not intended to limit the present invention, and besides the above shapes, other modifications and changes of shapes that can achieve the effect should be included in the protection scope of the present invention.

In the process of using the adhesive member 110, since the adhesive member 110 is usually adhered to the face of the user, in order to take care of the user's feeling of use and to reduce the inferior feeling of the user due to using the adhesive member 110 as much as possible, the above-mentioned gelatin patch 111 may be used when the adhesive member 110 is installed, so that the user can more easily hide the adhesive member 110 when using the adhesive member 110; it is also possible to change the shape of the adhesive element 110 such that the adhesive element 110 is more aesthetically pleasing, i.e. the adhesive element 110 is more personalized while ensuring a degree of fit.

Further, as can be seen from the above, the adhesive member 110 may be attached to the face or neck of the user, and when the adhesive member 110 is attached to the face of the user, the adhesive member 110 is relatively positioned behind the cheek of the user because the contact area of the muscles behind the cheek is large, and such an attachment means corresponds to a uniform force applied to the half face of the user, thereby preventing the occurrence of ear sores in the user. When the adhesive member 110 is adhered to the neck of the user, the contact area is ensured, and the adhesive member 110 is prevented from being too obvious, so that the adhesive member 110 is easy to hide, and the user is prevented from having a self-inferior situation due to the fact that the adhesive member 110 is too obvious.

In summary, referring to fig. 1 to 4, since the placement period of the bracket is different from 1 month to 2 months, when the fixing device 100 is in use, the tensioning degree of the extracorporeal recovery wire 140 can be adjusted by rotating the rotating bracket 132 and adjusting the number of turns of the extracorporeal recovery wire 140 wound around the rotating bracket 132, so that the contact stress between the extracorporeal recovery wire 140 and the contact part of the user can be adjusted by adjusting the tensioning degree of the extracorporeal recovery wire 140 in the long-term placement period of the bracket, and the comfort of the user can be further improved by reducing the tensioning force; furthermore, the tension of the extracorporeal recovery line 140 may be further adjusted by separating the first connector 120 and the second connector 130.

Therefore, by adjusting the tension of the extracorporeal recovery wire 140, discomfort in the throat of the user can be avoided, and pain caused by damage to the skin around the wings and ears of the user can be avoided, so that the discomfort of the user can be reduced, and the life quality of the user can be improved.

It should be noted that, in the process of adjusting the tension of the extracorporeal recovery line 140, the physician needs to adjust the tension according to the specific situation of the user; when the first connector 120 and the second connector 130 are separated from the clamping connection, the first connector 120 and the second connector 130 are separated from the clamping connection when the esophagus does not move frequently (such as the user has a rest or sleeps) according to the medical orders, so that the pressure of the user is relieved intermittently, and the pain of the user is relieved. That is, in the process of adjusting the tension of the extracorporeal recovery wire 140 through the above steps, it is necessary to ensure that the stent located in the body of the user does not displace, so as to ensure the therapeutic effect of the stent.

Furthermore, at present, the esophageal stent is widely applied to medical problems of esophageal stenosis, esophageal and tracheal fistula and the like caused by various reasons in clinic, and for most cases, the stent needs to be arranged to be taken out to achieve the purpose of treatment when the stenosis is relieved, the fistula is healed or the next measure is taken. However, because the stent graft can not be firmly fixed on the esophagus for a long time, especially for benign patients, when the disease is relieved and the esophageal stenosis is eliminated, the stent graft is easy to shift and even fall into the gastric cavity and the intestinal cavity, thereby affecting the treatment effect of the stent graft, and even causing serious complications such as intestinal obstruction, intestinal perforation and the like. Therefore, the stent is generally left with an extracorporeal recovery thread, which is pulled through the mouth or nose to prevent the stent from shifting or falling. The stent is taken out until the esophageal stenosis of a patient is relieved or the fistula is healed, and the placing period is generally 1 to 2 months; in the process of adopting the stent for treatment, the treatment time is longer, usually 1 month to 2 months, but the traditional stent recovery line is fixed at the ear root of a patient, and the diameter of the recovery line is very thin, and the ear is a cartilage tissue, so that pain nerves are rich, no muscle is buffered, and the contact area is small. When the recovery line is subjected to certain traction force of the bracket, the recovery line cuts the ears of the patient like a knife, and the ears are quickly pressed to form sores. To solve the above problem, please refer to fig. 1-9, fig. 9 shows the structure of the fixing device for external recovery wires in an embodiment of the present invention, the present invention provides an external recovery wire fixing device 200, the external recovery wire fixing device 200 includes a hose 210 and the fixing device 100.

Wherein, the proximal end of the flexible tube 210 is connected to the adhesive member 110, the flexible tube 210 is sleeved outside the extracorporeal recovery line 140, and the distal end of the flexible tube 210 is used for extending into the body of the patient.

It should be noted that, when the flexible tube 210 is manufactured, the flexible tube 210 may be made of silica gel, and when the distal end of the flexible tube 210 is used to extend into the body of the patient, the flexible tube 210 needs to enter the esophagus from the nasal cavity, so that the traditional mode that the extracorporeal recovery line 140 is directly contacted with the user is changed into the mode that the flexible tube 210 is contacted with the user, thereby increasing the contact area with the user, further relieving the oppression of the extracorporeal recovery line 140 on the esophagus, throat and nasal wing, and further alleviating the pain of the user.

Further, in order to measure the length of the hose 210 extending into the user's body, the outer circumferential surface of the hose 210 is provided with length marks 211 along the extending direction of the hose 210.

In order to facilitate the sleeving of the flexible tube 210 outside the extracorporeal recovery wire 140, in the present embodiment, the extracorporeal recovery wire fixing device 200 further includes a lead hook disposed inside the flexible tube 210, and the lead hook is used for guiding the proximal end of the extracorporeal recovery wire 140 to extend from the distal end of the flexible tube 210 and to extend from the proximal end of the flexible tube 210.

It should be noted that, when the lead hook is manufactured, in order to facilitate the operation of the physician, after the lead hook passes through the flexible tube 210, two ends outside the flexible tube 210 are respectively provided with a hook end and a hand ring end, the hook end is used for hooking the extracorporeal recovery line 140, and the hand ring end is used for facilitating the handling of the physician, so as to facilitate the operation of the physician. When the lead hook leads the proximal end of the outer conductor retrieval line 140 into the distal end of the flexible tube 210 and out of the proximal end of the flexible tube 210, the lead hook is detached from the cartilage.

Based on the above, please refer to fig. 1-10, fig. 10 shows the structure of the stent medical device in the embodiment of the present invention, the embodiment of the present invention provides a stent medical device 300, the stent medical device 300 comprises an internal stent 310, an external recovery wire 140 and the above-mentioned external recovery wire fixing device 200;
