However, those skilled in the art should know that the present application can also be realized in other embodiments without these specific details. In other cases, the detailed description of well-known systems, devices, circuits and methods is omitted, so as not to obscure the description of the present application with unnecessary details.

[0033] The tubular stomach grabber provided by the present application, in combination with the description of the drawings Figure 1 to the drawings Figure 5It can be seen that the tubular gastric grasper mainly includes the following parts or components: flexible catheter 10, housing 21, gripper 23, and drive assembly 30.

[0034] In this invention, a clamping component 20 is provided inside the lower end of the flexible conduit 10. The clamping component 20 extends or retracts from the lower end of the flexible conduit 10 under the drive of the lifting component 40. Specifically, the clamping component 20 includes a housing 21 slidably disposed inside the lower end of the flexible conduit 10. The housing 21 has a hollow structure and is connected to the lifting component 40. The lifting component 40 is used to drive the housing 21 to rise and fall. Two grippers 23 are symmetrically disposed at the bottom of the housing 21, and their upper ends are slidably connected to the bottom of the housing 21. The driving component 30 is connected to the two grippers 23 respectively and is used to drive the two grippers 23 to move closer or further apart.

[0035] The flexible catheter 10 moves the clamping assembly 20 and the lifting assembly 40. When it reaches the tubular stomach, the flexible catheter 10 stops moving. The lifting assembly 40 drives the housing 21 to move until the two grippers 23 extend from the lower end of the flexible catheter 10. Then, the driving assembly 30 drives the two grippers 23 to move closer to each other until they grasp the tubular stomach, thereby suspending the tubular stomach. This can effectively reduce damage to surrounding tissues and lower the risk of complications.

[0036] Specifically, the tip of the flexible catheter 10 uses the same technology as the tip of the endoscope, and has the ability to bend in four directions, that is, it can bend freely in four directions: up, down, left, and right. Therefore, the technology is widely used and will not be described in detail.

[0037] Specifically, the lower end of the flexible catheter 10 is equipped with a probe and a light source. This allows for easy location and clamping of the tubular stomach. In conjunction with the flexible catheter 10 and the retractable clamping assembly 20, damage to surrounding tissues can be further reduced during travel.

[0038] Specifically, the use of the flexible catheter 10 provides better compliance and adaptability, allowing the flexible catheter 10 to move flexibly in the body and reducing pressure and damage to surrounding tissues.

[0039] Specifically, the gripper 23 can be made of silicone or titanium alloy.

[0040] Specifically, the clamping component 20 extends or retracts under the precise drive of the lifting component 40, which can more accurately position and operate the device, reducing unnecessary contact and damage to surrounding tissues.

[0041] As one embodiment, in conjunction with the appendix to the specification Figure 2 To be continued Figure 4It can be seen that the driving assembly 30 comprises a lifting block 31 horizontally arranged in the shell 21 and lifted under the driving of a first driving source 32; two moving blocks 33 are symmetrically arranged on both sides of the lifting block 31 and connected with the lifting block 31, and the lower ends of the two moving blocks 33 are respectively connected with the upper ends of two clamping jaws 23 penetrating through a sliding groove (not shown in the figure) in the bottom of the shell 21, so that when the first driving source 32 drives the lifting block 31 to lift, the lifting block 31 drives the two moving blocks 33 to move towards or away from each other.

[0042] The first driving source 32 drives the lifting block 31 to lift, and the lifting block 31 drives the two moving blocks 33 to move towards or away from each other, and the two moving blocks 33 drive the two clamping jaws 23 to clamp or release the tubular stomach.

[0043] Specifically, the first driving source 32 can be a pneumatic cylinder.

[0044] Specifically, the two sides of the lifting block 31 are provided with two first inclined surfaces 311, and the side of the two moving blocks 33 facing the two first inclined surfaces 311 is provided with two second inclined surfaces 331, the two first inclined surfaces 311 are matched with the two second inclined surfaces 331, the second inclined surface 331 is provided with a T-shaped guide groove 332 along the length direction thereof, and the first inclined surface 311 is provided with a T-shaped guide key 312 matched with the T-shaped guide groove 332.

[0045] The height of the lifting block 31 is less than the height of the moving block 33, and in the lifting process of the lifting block 31, the T-shaped guide key 312 slides in the T-shaped guide groove 332, and at the same time of sliding, the moving block 33 is also pulled to move horizontally due to the T-shaped design, and the two sides of the lifting block 31 simultaneously pull the moving block 33 to move towards or away from each other.

[0046] Specifically, the second inclined surface 331 can also be provided with a dovetail groove along the length direction thereof, and the first inclined surface 311 can also be provided with a dovetail block matched with the dovetail groove.

[0047] As an embodiment, the description is combined with the drawings Figure 5 It can be seen that the lifting assembly 40 comprises a first screw rod 41 arranged in the flexible guide pipe 10, the lower end of which is connected with the shell 21, and the upper end thereof penetrates through a fixed plate 43 fixedly arranged in the flexible guide pipe 10 above the shell 21, and the first screw rod 41 is lifted under the driving of a second driving unit; a first optical axis 42 is arranged in parallel with the first screw rod 41, the lower end of which is connected with the shell 21, and the upper end thereof is slidably connected with the fixed plate 43. The second driving unit comprises a first gear 45 rotatably arranged on the fixed plate 43 and threadedly connected with the first screw rod 41; a second gear 441 is arranged on the fixed plate 43 and rotates under the driving of a second driving source 44, and the second gear 441 is engaged with the first gear 45.

[0048] The second driving source 44 drives the second gear 441 to rotate, the second gear 441 drives the first gear 45 to rotate, the first gear 45 drives the first screw 41 to lift, and the first screw 41 drives the shell 21 to lift, so that the optical axis 42 can keep the shell 21 to lift stably.

[0049] Specifically, the second driving source 44 can be a reversible motor.

[0050] In the embodiment, the shell 21 is connected with the flexible catheter 10 through the lifting assembly 40. Figure 1 , the flexible catheter 10 is connected with the lifting assembly 40 through the driving assembly 30. Figure 2 It can be known that the protective film 11 is arranged between the two clamping jaws 23, the two clamping jaws 23 are connected with the inner sides of the two clamping jaws 23 respectively, and the middle of the upper end of the protective film 11 is connected with the lower end of the lifting block 31.

[0051] The clamping jaws 23 can also cause damage to the tubular stomach when clamping the tubular stomach, so the protective film 11 is attached to the inner sides of the two clamping jaws 23, so that the clamping jaws 23 clamp the tubular stomach through the protective film 11, and the tubular stomach can be effectively protected from being damaged when being clamped, and because the upper end of the protective film 11 is gradually redundant when the two clamping jaws 23 are close to each other, the middle of the upper end of the protective film 11 is connected with the lower end of the lifting block 31, so that the upper end of the protective film 11 also moves when the lifting block 31 moves up and down, and is always kept on the inner sides of the two clamping jaws 23, so that the situation that the protective film 11 is too long is avoided.

[0052] Specifically, a plurality of anti-skid patterns are arranged on the inner sides of the two clamping jaws 23 respectively, so that the friction force can be effectively increased, and the situation that the tubular stomach slips when being clamped can be prevented.

[0053] The tubular stomach grabber provided by the utility model is used, and the specific operation process is as follows:

[0054] The flexible catheter 10 drives the clamping assembly 20 and the lifting assembly 40 to move, stops moving when the flexible catheter 10 moves to the tubular stomach, the lifting assembly 40 drives the shell 21 to move, until the two clamping jaws 23 stretch out from the lower end of the flexible catheter 10, then the driving assembly 30 drives the two clamping jaws 23 to be close to each other until the tubular stomach is grabbed, so that the tubular stomach is suspended, the damage to the surrounding tissues can be effectively reduced, and the risk of complications is reduced.
