Description

Technical Field

[0001] The utility model relates to the technical field of ligation staplers, and more specifically, to a disposable electric multi-ring ligation stapler with ablation. Background Art

[0002] A ligation stapler is a medical device used for treating hemorrhoids. The ligation stapler blocks the blood supply of hemorrhoids or reduces venous reflux by tightening an elastic thread, reduces the congestion and hypertrophy of hemorrhoids or blood stasis, causes ischemia, atrophy, and necrosis, and the hemorrhoids gradually fall off, and the wound tissue repairs and heals. The ligation device is a safe and effective method for treating hemorrhoids. It does not require a surgical incision, will not cause damage to surrounding tissues, and will not cause complications such as infection.

[0003] Most of the existing ligation staplers are single ligation. After ligation, it is necessary to wait for the ligated tissue to necrose and fall off to complete the whole process, which is not convenient to operate. The convenience of doctors during the operation is poor. At the same time, the wound healing time is long, which prolongs the pain and discomfort of patients, and the use effect is poor.

One end of the connecting pipe is fixedly communicated with the handle, and the ligation pipe is fixedly communicated at the end of the connecting pipe away from the handle. An ablation component is arranged between the handle and the connecting pipe. The ablation component includes a trigger, an ablation knife head, an ablation switch, and a toothed plate. The trigger is movably connected to the inside of the handle through a bearing. The ablation switch is located on one side of the trigger and is fixedly installed inside the handle. The ablation knife head is movably arranged inside the connecting pipe, and one end of the ablation knife head is fixedly connected to the toothed plate.

[0006] Further, a toothed disc is fixedly connected to the top end of the trigger, and the toothed disc meshes with the toothed plate.

[0007] Further, an ablation controller interface is fixedly installed at the bottom end of the handle.

[0008] It can be seen that in the above technical solution, the ablation controller interface is connected to the plug of the ablation control cabinet.

[0010] Further, a driving mechanism and a wire reel are installed inside the handle, and a wire is fixedly connected between the wire reel and the ligation coil.

[0011] It can be seen that in the above technical solution, the wire reel drives the wire to pull the ligation coil along a predetermined direction and tighten the root of the tissue to be ligated.

[0012] Further, a wire-receiving switch is fixedly installed at the rear side of the handle.

[0013] It can be seen that in the above technical solution, it is convenient to control the driving mechanism to drive the wire reel to rotate.

[0014] Further, a negative pressure pump is fixedly installed inside the handle. The input end of the negative pressure pump is fixedly communicated with an air pipe, and the air pipe is communicated with the ligation tube.

[0015] It can be seen that in the above technical solution, the negative pressure pump starts to work, and extracts the air near the ligation tube through the air pipe to form a negative pressure at the ligation opening, so that the tissue to be ligated is sucked into the ligation tube.

[0027] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Referring to the attached Figures 1-3 , the disposable electric multi-ring ligation anastomosis device with ablation of this embodiment includes a handle 1, a connecting pipe 2 and a ligation tube 3. One end of the connecting pipe 2 is fixedly communicated with the handle 1, and the ligation tube 3 is fixedly communicated at the end of the connecting pipe 2 away from the handle 1. An ablation assembly is arranged between the handle 1 and the connecting pipe 2. The ablation assembly includes a trigger 5, an ablation knife head 8, an ablation switch 12 and a tooth plate 13. The trigger 5 is movably connected to the inside of the handle 1 through a bearing. The ablation switch 12 is located on one side of the trigger 5 and is fixedly installed inside the handle 1. The ablation knife head 8 is movably arranged inside the connecting pipe 2, and one end of the ablation knife head 8 is fixedly connected to the tooth plate 13.

[0029] Furthermore, a tooth disk is fixedly connected to the top end of the trigger 5, and the tooth disk meshes with the tooth plate 13. An ablation controller interface 7 is fixedly installed at the bottom end of the handle 1.

[0030] Further, a ligation coil 4 is sleeved on the outer edge position of the end of the connecting tube 2 away from the handle 1. A driving mechanism 11 and a wire reel 14 are installed inside the handle 1, and a wire is fixedly connected between the wire reel 14 and the ligation coil 4. A wire-receiving switch 9 is fixedly installed on the rear side of the handle 1, and a negative pressure pump 10 is fixedly installed inside the handle 1. The input end of the negative pressure pump 10 is fixedly communicated with an air tube 15, and the air tube 15 is communicated with the ligation tube 3. A negative pressure switch 6 is fixedly installed on the front side of the handle 1.

[0031] The usage method of this embodiment is as follows:

[0032] During use, align the ligation tube 3 with the tissue to be ligated, turn on the negative pressure switch 6, and the negative pressure pump 10 starts to work. It extracts the air near the ligation tube 3 through the air tube 15 to form a negative pressure at the ligation opening, so that the tissue to be ligated is sucked into the ligation tube 3. Then, toggle the wire-receiving switch 9, so that the driving mechanism 11 drives the wire reel 14 to rotate. The wire reel 14 drives the wire to pull the ligation coil 4 along a predetermined direction and tighten the root of the tissue to be ligated. When a certain degree of tightening force is reached, the tail of the ligation coil 4 disconnects, and the wire reel 14 stops working to complete the ligation action. It is for single use. Turn off the negative pressure pump 10 through the negative pressure switch 6, so that the negative pressure near the ligation tube 3 disappears, and the ligated tissue is exposed on the outer surface of the tissue;

[0033] Connect the ablation controller interface 7 to the plug of the ablation control cabinet, press the trigger 5, which drives the gear disk to rotate, and then drives the toothed plate 13 and the ablation knife head 8 to move horizontally, and the ablation knife head 8 extends out of the connecting tube 2 and pierces the exposed and ligated tissue. At the same time, during the process of pressing the trigger 5, the trigger 5 will trigger the ablation switch 12, and the ablation knife head 8 can perform ablation work when piercing the tissue until the ablation is completed. Similarly, press the trigger 5 in the reverse direction to retract the ablation knife head 8. The operation is simple, which not only improves the convenience of the doctor during the operation, but also greatly shortens the healing time of the patient, and has a good use effect.
