Description

Technical Field

[0001] The present invention relates to the technical field related to medical instruments, and in particular to a multifunctional foreign body forceps for gastroenterology. Background Art

[0002] When food fragments, coins, toys, fish bones and other foreign objects are accidentally swallowed, if they are not removed in time, it may cause serious complications such as perforation, bleeding or infection. Therefore, doctors will use foreign body forceps to remove foreign objects safely and effectively during treatment. Therefore, digestive forceps are very important tools in gastroenterology.

[0003] When the swallowed foreign body is large, it will get stuck in the intestine. Since the intestine has autonomous peristaltic movement, the contraction of the intestine may cause the foreign body to be further entangled, making it more difficult to move. In addition, strong intestinal contraction may cause damage to the tissue around the foreign body, increasing the risk of bleeding and perforation. However, the existing foreign body forceps cannot limit the contraction of the intestine during the removal of the foreign body, which can easily cause damage to the intestine during the removal process. Summary of the invention

[0004] In order to overcome the shortcomings of existing foreign body forceps that they cannot restrict intestinal contraction during the process of removing foreign bodies and are likely to cause intestinal damage during the process, the present invention provides a multifunctional foreign body forceps for gastroenterology.

[0006] Furthermore, it also includes a pull rope three; at least six pull ropes three are fixedly connected to the inner side of the support cover; the pull rope three passes through the connecting pipe two and is connected to the driving component.

[0007] Furthermore, the driving assembly includes an electric push rod 1, a connecting plate 1, an electric push rod 2, a connecting plate 2, an electric push rod 3 and a connecting plate 3; the controller is fixedly connected to at least two electric push rods 1; the telescopic parts of all electric push rods 1 are commonly fixedly connected to the connecting plate 1; the connecting plate 1 is connected to all the pull ropes 1; the connecting tube 2 is fixedly connected to at least four electric push rods 2; the telescopic parts of all electric push rods 2 are commonly fixedly connected to the connecting plate 2; the connecting plate 2 is connected to all the pull ropes 2; the connecting tube 2 is fixedly connected to at least four electric push rods 3; the telescopic parts of all electric push rods 3 are commonly fixedly connected to the connecting plate 3; the connecting plate 3 is connected to all the pull ropes 3; the electric push rod 1, the electric push rod 2 and the electric push rod 3 are respectively connected to an external power supply.

[0008] Furthermore, the driving component also includes an electric push rod four; the controller is fixedly connected to at least four electric push rods four; the telescopic parts of all electric push rods four are commonly fixedly connected to the connecting pipe two; and the electric push rod four is connected to an external power supply.

[0009] Furthermore, it also includes a protrusion; a plurality of protrusions are fixedly connected to the inner side of the support cover.

At this time, the support cover will wrap the foreign object and the sharp part of the foreign object, thereby preventing the sharp part of the foreign object from scratching the intestine when it is taken out.

[0019] By moving the support cover away from the clamping block, the clamping block will be in a leaked state, and the foreign matter can be clamped directly, thereby reducing the use of the support cover and ensuring its service life.

[0020] When the foreign object is taken out, the support cover will wrap the foreign object, and when the support cover is deformed and gathered, the protrusion will play a clamping role, thereby preventing it from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] It also includes a pull rope three 10; six pull ropes three 10 are fixedly connected to the inner side of the support cover 7; the pull rope three 10 passes through the connecting pipe two 6 and is connected to the driving component.

[0032] The driving assembly includes an electric push rod 101, a connecting plate 102, an electric push rod 2 103, a connecting plate 2 104, an electric push rod 3 105 and a connecting plate 3 106; the controller 1 is fixedly connected to two electric push rods 101; the telescopic parts of all electric push rods 101 are commonly fixedly connected to the connecting plate 102; the connecting plate 102 is connected to all the pull ropes 15; the connecting tube 26 is fixedly connected to four electric push rods 2 103; the telescopic parts of all electric push rods 2 103 are commonly fixedly connected to the connecting plate 2 104; the connecting plate 2 104 is connected to all the pull ropes 2 9; the connecting tube 26 is fixedly connected to four electric push rods 3 105; the telescopic parts of all electric push rods 3 105 are commonly fixedly connected to the connecting plate 3 106; the connecting plate 3 106 is connected to all the pull ropes 3 10; the electric push rod 101, the electric push rod 2 103 and the electric push rod 3 105 are respectively connected to an external power supply.

[0033] The driving assembly also includes four electric push rods 107; the controller 1 is fixedly connected to four electric push rods 107; the telescopic parts of all the four electric push rods 107 are commonly fixedly connected to the connecting pipe 2 6; the four electric push rods 107 are connected to an external power supply.

[0034] It also includes a protrusion 111; a plurality of protrusions 111 are fixedly connected to the inner side of the support cover 7, and the protrusions 111 can clamp foreign objects to prevent them from falling off when being taken out.

[0035] The rotation path of the clamping block 3 is located between the two reinforcing strips 8, so as to avoid the reinforcing strips 8 being blocked by the rotating clamping block 3 when the deformation is driven, resulting in the inability to clamp the foreign matter.

[0036] The connecting pipe 2 6 is provided with four slide grooves, and the connecting pipe 1 2 is provided with four slide bars, each of which is located in a corresponding slide groove, so that the connecting pipe 2 6 can be limited by the slide bars and the slide grooves to prevent the connecting pipe 2 6 from rotating relative to the support cover 7 after movement, causing the clamping block 3 and the reinforcing strip 8 to be misaligned.

[0037] The specific working steps are:

[0038] When the doctor needs to remove the foreign body accidentally swallowed by the patient, the patient is first made to lie on the bed, and then the controller 1 is placed on the table next to the bed. Then the doctor takes the connecting tube 2 6, and pushes the connecting tube 1 2, the clamp 3, the torsion spring 4, the pull rope 1 5, the connecting tube 2 6, the support cover 7, the reinforcing strip 8, the pull rope 2 9, the pull rope 3 10, the camera 11 and the lighting lamp 12 into the patient's intestine. During the movement in the intestine, the lighting lamp 12 is turned on to illuminate the intestine, and the camera 11 is turned on to illuminate the intestine. 11 will take a picture of the situation in the intestine, so as to accurately find the position of the foreign body. When the clamp block 3 reaches the foreign body, the movement of the connecting tube 2 6 is stopped first. At this time, the clamp block 3 is in an open state. Then the doctor adjusts the position of the clamp block 3 through the connecting tube 2 6 to align the opened clamp block 3 with the foreign body, and then moves the clamp block 3 again to make it contact with the foreign body. Then the electric push rod 101 pushes the connecting plate 102 to drive the two pull ropes 5 to move, so that each pull rope 5 pulls the corresponding clamp block 3 to rotate towards each other, so that The clamping block 3 in the open state rotates and closes. At this time, the closed clamping block 3 will clamp the foreign body, and then the connecting tube 2 6 can be pulled to drive the clamping block 3 and the clamped foreign body away from the intestine, thereby removing the foreign body. When adjusting the position of the clamping block 3, the electric push rod 2 103 pulls the pull rope 2 9 to move through the connecting plate 2 104. At this time, the pull rope 2 9 will pull the root of the support cover 7 to deform and expand it into a trumpet shape. At this time, the end of the support cover 7 will contact the intestine, and as the expansion amplitude of the support cover 7 increases, it will squeeze the intestine, thereby The intestine is slightly expanded, and the reinforcing strip 8 provided in the support cover 7 can play a supporting role to prevent the support cover 7 from being squeezed and deformed. After squeezing the intestine, the support cover 7 will expand the intestine, thereby facilitating the removal of the stuck foreign matter. After the intestine is expanded, it is convenient to observe the stuck foreign matter to see whether the sharp part of the foreign matter is inserted into the intestine, thereby facilitating the formulation of different treatment plans for different foreign matter situations and reducing treatment risks. After the clamping block 3 clamps the foreign matter, the pull rope 2 9 can be controlled to return to its original position.

[0039] After long-term use of the support cover 7, the connection between the support cover 7 and the connecting tube 2 6 will be deformed, resulting in an expanded state in the initial state. The expanded support cover 7 will not be easy to be pushed into the intestine from the patient's throat, and the support cover 7 will also contact the intestine when the intestine moves, which will cause the clamp 3 to be difficult to move in the intestine. Therefore, when it is necessary to push the device into the intestine, the electric push rod 3 105 is controlled to push the connecting plate 3 106 to drive the pull rope 3 10 to move, so that the pull rope 3 10 pulls the inner side of the support cover 7, and then the support cover 7 gathers inward, thereby avoiding the support cover 7 from deforming autonomously, resulting in difficulty in pushing into the intestine and difficulty in moving in the intestine. It should be noted that when the pull rope 3 10 pulls the support cover 7, the electric push rod 2 103 will drive the connecting plate 2 104 to move toward the connecting tube 2 6, so that the connecting plate 2 104 drives the pull rope 2 9 to move together, and then when the support cover 7 is pulled and drives the pull rope 2 9, the pull rope 29 has a margin that can be pulled.

[0040] When the sharp part of the foreign body has been inserted into the intestine, the sharp part will be inserted into the intestine in an inclined shape, and the foreign body needs to be clamped by the clamping block 3 first, and then the foreign body is driven to move in the opposite direction of the insertion direction, so as to pull out the sharp body. At this time, the foreign body is driven to move and it is easy to insert it into the intestine again. Therefore, at this time, the end of the connecting tube 2 6 can be pushed by the electric push rod 4 107 to move into the intestine again, so that the connecting tube 2 6 drives the support cover 7 to move toward the foreign body. When the support cover 7 moves, the intestine will expand, so that a gap will appear between the intestine and the sharp part of the foreign body, so that the support cover 7 will wrap the sharp part of the foreign body, and then the pull rope 3 10 will pull the support cover 7 to shrink the support cover 7. At this time, the support cover 7 will wrap the foreign body and the sharp parts of the foreign body, thereby preventing the sharp parts of the foreign body from scratching the intestine when the foreign body is taken out; and when clamping a small foreign body, there is no need to use the support cover 7 to wrap the foreign body. At this time, in order to facilitate the movement of the clamping block 3 in the intestine, reduce the use of the support cover 7, and increase the service life, the electric push rod 4 107 drives the connecting pipe 2 6 to move away from the clamping block 3, so that the connecting pipe 2 6 drives the support cover 7 to move, and the support cover 7 moves away from the clamping block 3. At this time, the clamping block 3 will be in a leaking state, and the foreign body can be clamped directly, thereby reducing the use of the support cover 7 and ensuring its service life.

[0041] Taking into account that some foreign objects are not easily clamped by the clamp block 3 when removing foreign objects, and are easily separated from the clamp block 3 during the removal process, the support cover 7 will wrap the foreign objects when removing the foreign objects, and when the support cover 7 is deformed and gathered, the protrusion 111 will play a clamping role, thereby playing a role in preventing them from falling off.

[0042] Example 2

[0043] On the basis of Example 1, Figure 2 and Figure 4As shown, the support cover 7 is provided with a reinforcement portion 7001, through which the area between the two reinforcement strips 8 on the support cover 7 is prevented from being squeezed and deformed.

[0044] The reinforcing portion 7001 is initially petal-shaped, so as to facilitate the contraction of the support cover 7 before entering the stomach and intestines.

[0045] It also includes an electromagnet 201; three electromagnets 201 are fixedly connected to the bottom of the controller 1; the electromagnets 201 are used to prevent the controller 1 from moving when removing foreign objects.

[0046] The specific working steps are:

[0047] Taking into account that when the support cover 7 squeezes the intestine, the contracted intestine is easy to squeeze the area on the support cover 7 except the reinforcing strip 8, causing the support cover 7 to deform and making it impossible to expand the intestine, a reinforcing portion 7001 is provided. When the intestine contracts and squeezes the support cover 7, the reinforcing portion 7001 is not easy to deform, resulting in the intestine being squeezed and expanded by the support cover 7. Moreover, since the reinforcing portion 7001 is in the shape of petals, the reinforcing portion 7001 is not easy to be squeezed and deformed when squeezed by the intestine, and it can be ensured that when the support cover 7 contracts, the reinforcing portion 7001 can also be contracted.

[0048] When the doctor moves the connecting tube 26, the controller 1 is easily moved. If the controller 1 falls accidentally, it is easy to pull the connecting tube 26, thereby affecting the removal of foreign matter. Therefore, after the controller 1 is placed on the placement table, the electromagnet 201 will be attracted to the placement table, thereby fixing the controller 1 to prevent it from being pulled and moved.
