Thus, the following detailed description of the embodiments of the invention provided in the accompanying drawings are not intended to limit the scope of the invention as claimed, but are merely representative of selected embodiments of the invention.

Example

Referring to FIG. 1 , an embodiment of the present invention provides a device for recovering gastrointestinal wounds, including a clamping member 10 , a connecting wire 20 and a locking mechanism 30 , and the clamping member 10 is used to clamp at least two sides of the wound. At the edge, the connecting wire 20 is used to pull the clip 10 and make the clip 10 gather the wound, and the locking mechanism 30 is used to fix the connecting wire 20 .

Further, the clamping member 10 is located at one end of the locking mechanism 30, one end of the connecting wire 20 passes through the locking mechanism 30 and is connected with the clamping member 10, and the other end of the connecting wire 20 is connected to the outside of the patient, and the medical staff can pull The connecting wire 20 operates, and the clip 10 is used to gather the wound under the action of the connecting wire 20 .

2 and 3, in this embodiment, the digestive tract wound recovery device further includes an outer tube 40 and an inner tube 50, and the locking mechanism 30 includes a first abutting member 31 and a second abutting member 32, One end of the inner tube 50 is detachably connected to the second abutting member 32, and one end of the outer tube 40 is detachably connected to the first abutting member 31, and the outer tube 40 is sleeved outside the inner tube 50, where the outer tube 40 Both the inner tube 50 and the inner tube 50 are flexible tubes and are operated endoscopically.

The first abutting member 31 is a hollow truncated cone, and may also be in other shapes. And the first abutting member 31 is provided with a first hole 310 and a second hole 312 that communicate with each other, the first hole 310 is used for connecting with the second abutting member 32 , and the second hole 312 is used for connecting with the clamping member 10 . .

The first hole 310 is disposed at one end of the first abutting member 31 away from the second abutting member 32 , the second hole 312 is disposed at an end of the first abutting member 31 close to the second abutting member 32 , the first hole 310 An internal thread 311 is provided, and the second abutting member 32 is a disc-shaped structure. Preferably, the second abutting member 32 here is set in a ring shape, so that the second abutting member 32 can be more conveniently connected with the first abutting member 32. The abutment piece 31 is connected. The outer wall of the second abutting member 32 is provided with an external thread 320 matching the inner thread 311 , the first abutting member 31 can be threadedly connected with the second abutting member 32 , and the first abutting member 31 and the second abutting member 32 When screwing is performed, the connecting wire 20 is clamped to keep the connecting wire 20 in a fixed state.

One end of the second hole 312 close to the first hole 310 is the first end 313 , and the other end is the second end 314 . The diameter of the second hole 312 gradually decreases from the second end 314 to the first end 313 . The piece 10 enters the second hole 312 from the second end 314 . As the diameter of the second hole 312 decreases, the clamping piece 10 shrinks continuously during the process of being pulled by the connecting wire 20 and gathers the wound at the same time.

In this embodiment, the clip 10 includes at least two clips 11, and the two clips 11 are disposed on opposite sides of the wound. The clip 11 includes a clip body 12 and a clip 13, and the clip 13 can directly clamp the edge of the wound. . One end of the clip body 12 close to the second end 314 is the third end 120 and the other end is the fourth end 121 . The cross-sectional area of the clip body 12 gradually increases from the third end 120 to the fourth end 121 . Similarly, the clip body 12 is provided with a structure of gradual cross section, which can increase the connection stability between the clip 10 and the hole wall of the second hole 312, and can better fix the wound.

In this embodiment, the outer wall of the second abutting member 32 is further provided with a cutting ring 321 , and the cutting ring 321 is used to cut off the redundant connecting wire 20 . After the first abutting member 31 and the second abutting member 32 are fixed to each other, the redundant connecting wire 20 needs to be cut off. It is only necessary to pull the connecting wire 20 against the cutting ring 321, and then slide it to one side to cut off the connection. Line 20. Here, the cutting ring 321 is arranged on the top of the external thread 320 . After the connecting wire 20 is cut off, the second abutting member 32 can be screwed into the first hole 310 to make the cutting ring 321 abut against the first hole 310 . The top edge can also play a role similar to a cushion, and can strengthen the connection stability of the first abutting member 31 and the second abutting member 32 .

When the device is in use, the first abutting member 31 and the clamping member 10 are first sent to the surface of the wound through the outer tube 40, the clamping member 10 is operated to clamp both sides of the wound, and the connecting wire 20 is operated to make the wound After the clamping pieces 10 are brought together to reach a fit state, then the inner tube 50 is operated, so that the first abutting piece 31 abuts on the top of the second abutting piece 32 and is threadedly connected with the first hole 310. After the connection between the abutting member 31 and the second abutting member 32 is basically stable, the connecting wire 20 is cut off by the cutting ring 321, and the first abutting member 31 is operated again to make the cutting ring 321 tightly abut the top of the second abutting member 32, Finally, the outer tube 40 and the inner tube 50 are taken out to complete the operation. During this process, a therapeutic drug may be introduced into the wound site through the inner tube 50 to speed up the healing of the wound.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
