Description

A digestive tract foreign body removal device

Technical Field

The present application belongs to the technical field of medical devices, and specifically relates to a device for removing foreign bodies from the digestive tract.

Background Art

Swallowing foreign objects refers to the patient accidentally or intentionally swallowing indigestible substances. Some foreign objects can be naturally discharged from the body through the digestive tract, but sharp foreign objects or foreign objects stuck in the digestive tract need to be removed from the digestive tract in time, especially some rusty iron nails, iron sheets and other foreign objects, which are very likely to damage the inner wall of the esophagus or gastric mucosa, causing digestive tract ulcers, local mucosal erosion, and even the risk of massive digestive tract bleeding. Therefore, when removing foreign objects from the digestive tract, sharp foreign objects should be avoided from scratching the digestive tract.

In current clinical operations, endoscopic forceps are often used to remove foreign objects in the digestive tract, and then the foreign objects are dragged through the digestive tract to the outside world by endoscopic forceps. However, in this process, doctors need to spend a lot of energy to find foreign objects in the digestive tract; when dragging foreign objects, they also need to avoid scratching the digestive tract with the sharp parts of the foreign objects.

Summary of the invention

In order to remove foreign objects in the digestive tract that can be magnetically attracted and prevent the foreign objects from damaging the digestive tract during the removal process, the present application provides a digestive tract foreign object removal device.

A digestive tract foreign body removal device comprises an elastic membrane, a fixed tube, an adjusting member arranged in the fixed tube and slidably connected to the fixed tube, and a plurality of support rods. The elastic membrane comprises a connecting area and a working area provided with a magnetic part. The connecting area is arranged around the working area and connected to the fixed tube through a plurality of support rods. The adjusting member is connected to the adjusting part of the working area and can drive the working area to move. The adjusting member can move along the axial direction of the fixed tube. When the adjusting member drives the adjusting part to move in a direction away from the fixed tube, the working area forms a working protrusion capable of absorbing foreign bodies. When the adjusting member drives the adjusting part to move in a direction close to the fixed tube, the working area is transformed from a working protrusion into a working cavity capable of wrapping foreign bodies.

When the elastic membrane becomes a working protrusion under the action of the adjusting part, the magnetic part of the working area can produce magnetic attraction with foreign objects such as iron sheets and iron nails in the digestive tract, and the iron sheets and other foreign objects are adsorbed on the working protrusion. When the working protrusion gradually turns into a working cavity, the iron sheet is brought into the working cavity by the magnetic attraction part, so that the elastic membrane can wrap the foreign object and avoid damage to the digestive tract during the removal of the foreign object.

In one embodiment of the present application, the elastic membrane does not undergo elastic deformation, and when in a natural state, the working area encloses a working cavity.

When the elastic membrane does not undergo elastic deformation, a working cavity can be naturally formed under the action of its own shape and elasticity. Therefore, after a foreign object enters the working cavity, the elastic membrane wraps the foreign object and takes the foreign object out of the body. In the process, the state of the working cavity can be maintained without the force of the adjusting part, thereby avoiding the situation where the adjusting part applies the wrong force to the elastic membrane, causing the foreign object to fall out of the working cavity.

In one embodiment of the present application, the projection of the elastic membrane on the cross-section of the fixed tube is circular, the projection of the working area on the cross-section of the fixed tube is circular, the projection of the adjustment part on the cross-section of the fixed tube is located at the center of the projection of the working area on the cross-section of the fixed tube, and the projection of the connection area on the cross-section of the fixed tube is arranged around the working area.

The projection of the elastic membrane on the cross section of the fixed tube is circular, the projection of the working area on the cross section of the fixed tube is circular, the projection of the adjusting portion on the cross section of the fixed tube is located at the center of the projection of the working area on the cross section of the fixed tube, and the projection of the connecting area on the cross section of the fixed tube is arranged around the working area. The distance from the edge of the elastic membrane to the working area is equal, which facilitates foreign objects in all directions to be adsorbed by the working protrusion.

In one embodiment of the present application, a plurality of support rods are arranged in an array around the axis of the fixed tube.

In one embodiment of the present application, the adjusting portion is connected to a clamp assembly, and an operating wire in the clamp assembly that can control the opening and closing of the clamp jaws passes through the adjusting portion, the fixing tube, and is connected to an operating handle.

When a working protrusion is formed in the working area, the clamp assembly can clamp heavy foreign objects or foreign objects in some special positions, and carry the foreign objects to the working protrusion, and firmly fix the foreign objects with the magnetic attraction of the magnetic part. When the working protrusion forms a working cavity, the elastic membrane wraps the jaws of the clamp assembly and the foreign objects it clamps, making it convenient to remove the foreign objects from the body.

In one embodiment of the present application, the clamp assembly does not generate magnetic attraction with the magnetic portion.

In one embodiment of the present application, the magnetic part and the adjusting part are arranged opposite to each other, and the magnetic part, the adjusting part and the adjusting member are arranged coaxially with the axis of the fixed tube.

In one embodiment of the present application, the digestive tract foreign body removal device also includes an isolation membrane, which is connected to the connecting area and the fixed tube. The isolation membrane, the elastic membrane and the fixed tube form an isolation cavity. The support rod is arranged in the isolation cavity, and the adjustment member passes through the isolation cavity and is connected to the adjustment part; when the working area forms a working cavity, the working cavity is arranged in the isolation cavity.

On the one hand, the isolation membrane can prevent human tissue from entering between the support rods and prevent human tissue from being damaged by the support rods. On the other hand, the isolation membrane and the elastic membrane form two layers of barriers. When foreign matter is too sharp and pierces the elastic membrane, the isolation membrane can isolate the foreign matter from contact with the digestive tract tissue and prevent foreign matter from damaging the tissue.

In one embodiment of the present application, the support rod is elastic; the digestive tract foreign body removal device also includes a sheath, and the fixed tube is arranged in the sheath and can move along the sheath; when the fixed tube moves in the direction of entering the sheath, the adjusting part enters the sheath, and the support rod and the elastic membrane undergo elastic deformation and are retracted in the sheath; when the fixed tube moves away from the sheath, the support rod and the elastic membrane are driven to leave the sheath, and the support rod and the elastic membrane change from a retracted state to an expanded state under the action of their own elasticity.

In one embodiment of the present application, the digestive tract foreign body removal device also includes an operating handle, which includes an operating body and a first operating member slidably connected to the operating body and a second operating member slidably connected to the first operating member, the operating body is connected to the sheath tube through a spring tube; the first operating member is connected to the fixed tube through a first operating line to drive the fixed tube to move along the sheath tube; the second operating member is connected to the adjusting member through a second operating line to drive the adjusting member to move along the axis of the fixed tube.

The present application has at least the following beneficial effects:

1. When the elastic membrane becomes a working protrusion under the action of the adjusting part, the magnetic part of the working area can produce magnetic attraction with foreign objects such as iron sheets and iron nails in the digestive tract, and foreign objects such as iron sheets are adsorbed on the working protrusion. When the working protrusion gradually turns into a working cavity, the iron sheet is brought into the working cavity by the magnetic attraction part, so that the elastic membrane can wrap the foreign object to avoid damage to the digestive tract during the removal of the foreign object.

2. When the elastic membrane does not undergo elastic deformation, a working cavity can be naturally formed under the action of its own shape and elasticity. Therefore, after a foreign object enters the working cavity, the elastic membrane wraps the foreign object and takes the foreign object out of the body. In the process, the state of the working cavity can be maintained without the force of the adjusting part, thereby avoiding the situation where the adjusting part applies the wrong force to the elastic membrane, causing the foreign object to fall out of the working cavity.

1 and 2 , the digestive tract foreign body removal device includes an elastic membrane 101, a fixed tube 301, and an adjusting member 201 disposed in the fixed tube 301 and slidably connected to the fixed tube 301. The adjusting member 201 can move along the axial direction of the fixed tube 301. The digestive tract foreign body removal device also includes a plurality of support rods 108. The elastic membrane 101 includes a connecting area 107 and a working area 102 provided with a magnetic portion 105. The connecting area 107 is disposed around the working area 102 and is connected to the fixed tube 301 through a plurality of support rods 108. The adjusting member 201 is connected to the adjusting portion 106 of the working area 102 and can drive the working area 102 to move. The elastic membrane 101 can be made of magnetic rubber provided with magnetic particles, and the magnetic particles are distributed in the working area 102. Of course, the elastic membrane 101 can also be made of other materials having magnetism and elasticity, which will not be repeated here.

In one embodiment of the present application, the projection of the elastic membrane 101 on the cross-section of the fixed tube 301 is circular, the projection of the working area 102 on the cross-section of the fixed tube 301 is circular, the projection of the adjustment part 106 on the cross-section of the fixed tube 301 is located at the center of the projection of the working area 102 on the cross-section of the fixed tube 301, the projection of the connection area 107 on the cross-section of the fixed tube 301 is arranged around the working area 102, and the annular connection area 107 is connected to the fixed tube 301 through multiple support rods 108.

The adjusting member 201 can move along the axial direction of the fixed tube 301. When the adjusting member 201 drives the adjusting portion 106 to move in a direction away from the fixed tube 301, see FIG3 . The support rod 108 limits the movement of the connecting area 107. Described in the direction shown in FIG3 , the adjusting member 201 only drives the working area 102 to move upward. The elasticity of the elastic membrane 101 itself causes the working area 102 and the connecting area 107 to undergo controllable elastic deformation. Finally, the working area 102 is higher than the connecting area 107. The working area 102 forms a working protrusion 103. See FIG4 . The working area 102 is provided with a magnetic portion 105. The magnetic portion 105 can interact with the magnetic metal to produce a magnetic effect, so that the working protrusion 103 can absorb foreign matter 701 in the digestive tract. Moreover, due to the shape of the working protrusion 103 and the fact that the connecting area 107 is not magnetic, the foreign matter 701 can be absorbed by the working protrusion 103. 01 Under the action of magnetic attraction, it can only be connected to the working protrusion 103 and will not be adsorbed on other components of the present application; so that the connection position of the foreign body 701 and the elastic membrane 101 is fixed; when the adjusting member 201 drives the adjusting part 106 to move in the direction close to the fixed tube 301, it is described in the direction shown in Figure 4, the working area 102 moves downward, and the working protrusion 103 formed by the working area 102 sinks to form a cavity, and the working area 102 is transformed from the working protrusion 103 to the working cavity 104. In this process, the foreign body 701 adsorbed on the working protrusion 103, due to the shape change of the working area 102, the working area 102 wraps the foreign body 701, and finally the foreign body 701 enters the working cavity 104 formed by the working area 102 under the adsorption action of the magnetic part 105, see Figure 5, the medical staff can take out the working cavity 104 to remove the foreign body 701.

In this process, due to the magnetic attraction, medical staff do not need to specifically clamp the foreign body 701 hidden in the folds of the digestive tract, and under the support of the adjustment member 201, the working protrusion 103 has a certain rigidity, which can easily enter the folds, and the magnetic force of the magnetic attraction part can be controlled to ensure the reliability and safety of the process of adsorbing the foreign body 701. It can adsorb the foreign body 701 and avoid excessive magnetic force, which may damage the digestive tract during the adsorption of the foreign body 701. The magnetic part 105 can also be an electromagnet, which is electrically connected to an external control device through a wire, so that the magnetic force of the magnetic part 105 can be controlled by controlling the current.

Referring to Figure 1, further, a plurality of support rods 108 are arranged in an axial array around the fixed tube 301 to ensure that when the elastic membrane 101 is deformed, the support rods 108 can provide stable support force to the elastic membrane 101, and limit the position change of the connection area 107, thereby ensuring that the working area 102 can undergo stable shape changes and ensure that the working area 102 can adsorb and wrap the foreign matter 701.

In one embodiment of the present application, the magnetic part 105 and the adjusting part 106 are arranged relative to each other, and the magnetic part 105, the adjusting part 106, and the adjusting member 201 are coaxially arranged with the axis of the fixed tube 301, referring to FIG3. After the magnetic part 105 absorbs the foreign matter 701, the foreign matter 701 can be located at the center position where the deformation occurs in the working area 102, so that in the process of the working area 102 being transformed from the working protrusion 103 to the working cavity 104, the adjusting member 201 can always drive the foreign matter 701 to move through the adjusting part 106 and the magnetic part 105, thereby ensuring that the working cavity 104 can wrap the foreign matter 701.

Technicians in the technical field to which the present application belongs can understand that the projection shape of the elastic membrane 101 and the working area 102 in the present application on the cross section of the fixed tube 301 is not necessarily limited to a circle, but can also be a square. The connection area 107 is arranged around the working area 102, and the projection of the connection area 107 on the cross section of the fixed tube 301 is a square ring. Of course, it can also be other shapes, which will not be repeated here.

Technicians in the technical field to which the present application belongs can understand that the magnetic part 105 in the present application can be set at the bottom of the working cavity 104, or, when the working area 102 is formed of magnetic rubber, the bottom and the wall of the working cavity are both provided with the magnetic part 105. The setting position of the magnetic part 105 is based on the fixation of the foreign body 701, which will not be repeated here.

Referring to FIG. 2 , in one embodiment of the present application, the elastic membrane 101 does not undergo elastic deformation, and when in a natural state, the working area 102 encloses a working cavity 104 .

When the elastic membrane 101 does not undergo elastic deformation, the working cavity 104 can be naturally formed under the effect of its own shape and elasticity, so that after the foreign body 701 enters the working cavity 104, the elastic membrane 101 wraps the foreign body 701, and in the process of taking the foreign body 701 out of the body, the state of the working cavity 104 can be maintained without the force of the adjusting member 201, thereby preventing the adjusting member 201 from giving the elastic membrane 101 an erroneous force, causing the foreign body 701 to fall out of the working cavity 104. In addition, when the elastic membrane 101 enters the digestive tract, the magnetic part 105 provided in the working area 102 is located in the working cavity 104, which can prevent the foreign body 701 from having a magnetic attraction with the magnetic part 105 too early, or from having an uncontrollable contact, so that the contact position of the foreign body 701 with the magnetic part 105 is incorrect.

When the working area 102 is transformed between the working cavity 104 and the working protrusion 103, the elasticity of the elastic membrane 101 enables it to maintain a certain shape during the transformation process, which is convenient for adsorbing and wrapping the foreign matter 701. In addition, the elasticity of the elastic membrane 101 enables it to adapt to the shapes of different foreign matter 701 when wrapping the foreign matter 701. The elastic membrane 101 can fit the foreign matter 701 to prevent the foreign matter 701 from scratching the digestive tract.

Referring to Figure 6, in one embodiment of the present application, the digestive tract foreign body removal device also includes an isolation membrane 109, which is connected to the connecting area 107 and the fixed tube 301. The isolation membrane 109, the elastic membrane 101 and the fixed tube 301 form an isolation cavity, the support rod 108 is arranged in the isolation cavity, and the adjustment member 201 passes through the isolation cavity and is connected to the adjustment part 106; when the working area 102 forms the working cavity 104, the working cavity 104 is arranged in the isolation cavity.

On the one hand, the isolation membrane 109 can prevent human tissue from entering between the support rods 108 and prevent human tissue from being damaged by the support rods 108. On the other hand, the isolation membrane 109 and the elastic membrane 101 form a two-layer barrier. When the foreign body 701 is too sharp and pierces the elastic membrane 101, the isolation membrane 109 can isolate the foreign body 701 from contact with the digestive tract tissue and prevent the foreign body 701 from damaging the tissue.

7 , in one embodiment of the present application, the support rod 108 is elastic; the digestive tract foreign body removal device also includes a sheath tube 401, and the fixed tube 301 is arranged in the sheath tube 401 and can move along the sheath tube 401; when the fixed tube 301 moves in the direction of entering the sheath tube 401, the adjusting member 201 enters the sheath tube 401, and the support rod 108 and the elastic membrane 101 undergo elastic deformation and are retracted in the sheath tube 401, so that the elastic membrane 101, the support rod 108 and other components are conveniently retracted in the sheath tube 401 and enter the digestive tract through the instrument channel of the endoscope; when the fixed tube 301 leaves the sheath tube 401, it drives the support rod 108 and the elastic membrane 101 to leave the sheath tube 401, and the support rod 108 and the elastic membrane 101 change from a retracted state to an expanded state under the action of their own elasticity, so that the elastic membrane 101 can cover a larger area, so that the elastic membrane 101 can absorb and wrap the foreign body 701 conveniently. When the elastic membrane 101 is connected to the isolation membrane 109 , the isolation membrane 109 can also move in and out of the sheath tube 401 along with the fixing tube 301 .

Furthermore, the digestive tract foreign body removal device also includes an operating handle, which includes an operating body and a first operating member 602 slidably connected to the operating body and a second operating member 604 slidably connected to the first operating member 602, the first operating member 602 is connected to a first guide rail 608, the second operating member 604 is slidably connected to the first guide rail 608, the operating body is connected to the sheath tube 401 through the spring tube 402; the first operating member 602 is connected to the fixed tube 301 through the first operating wire 603 passing through the spring tube 402, so as to drive the fixed tube 301 to move along the sheath tube 401, so that the fixed tube 301 enters and exits the sheath tube 401; the second operating member 604 is connected to the second operating wire 605 passing through the spring tube 402 Connected to the adjusting member 201, when the second operating member 604 moves along the first operating member 602, the position of the adjusting member 201 is adjusted by the second operating line 605 to drive the adjusting member 201 to move along the axis of the fixed tube 301, so that the working area 102 switches between the working protrusion 103 and the working cavity 104. The second operating member 604 and the first operating member 602 are slidably connected, and the second operating member 604 can move along the operating body with the first operating member 602, avoiding relative movement between the fixed tube 301 and the adjusting member 201, causing the adjusting member 201 to drive the working area 102 to move relative to the fixed tube 301, and finally causing the working area 102 to switch incorrectly.

Referring to FIG7 , in one embodiment of the present application, the adjustment portion 106 is connected to a clamp assembly, and the clamp assembly does not have a magnetic attraction with the magnetic portion 105, so as to prevent the clamp assembly from affecting the magnetic portion 105 in adsorbing foreign matter 701; an operating line capable of controlling the opening and closing of the clamp jaws in the clamp assembly passes through the adjustment portion 106, the fixed tube 301 and is connected to the operating handle, referring to FIG8 , the clamp assembly includes four connecting rods and a clamp arm 503 connected to two of the connecting rods, the four connecting rods include two second connecting rods 502 pivotally connected to each other and two first connecting rods 501 connected to the clamp arm 503, the two first connecting rods 501 are pivotally connected, and one of the first connecting rods 501 and A second link 502 is pivotally connected, another first link 501 is pivotally connected to another second link 502, the two first links 501 are respectively connected to the clamp arms 503, the two clamp arms 503 can approach or move away from each other at the same time, and the two clamp arms 503 form a jaw, the pivotal connection of the two second links 502 is connected to a third operating line 607, and the operating body is also slidably connected to a third operating member 606 connected to the third operating line 607. When the third operating member 606 moves, the pivotal connection of the two second links 502 is moved in a direction away from or close to the operating body through the third operating line 607, thereby controlling the opening and closing of the jaws.

In order to remove foreign object 701 more stably, the jaws can be used to clamp foreign object 701, and the magnetic part 105 can be used to fix foreign object 701. Finally, under the dual action of the magnetic part 105 and the jaws, foreign object 701 is firmly fixed, and the working area 102 wraps foreign object 701, and then foreign object 701 is safely removed.

Of course, another operating body may be provided, and the third operating member 606 and the third operating line 607 are connected to the operating body, which will not be described in detail here.
