Description

Technical Field

[0001] The present application relates to the field of hemorrhoid treatment, and in particular to a disposable hemorrhoid ligation stapler cutting and firing assembly. Background Art

[0002] Hemorrhoid band ligation is a commonly used method for treating hemorrhoids with definite efficacy. The principle is to ligate a special rubber ring (such as a rubber ring, latex ring, silicone ring, elastic coil, etc.) around the root (or base) of the internal hemorrhoids, thereby using the elastic retraction force of the rubber ring to block the blood supply to the hemorrhoids, causing them to necrotize, atrophy, and fall off, thereby achieving the purpose of healing.

[0003] At present, internal hemorrhoids are usually ligated by using a disposable hemorrhoid ligation stapler in combination with a gun head equipped with an elastic line. However, after the hemorrhoids are ligated, a person needs to use a shearing tool to reach deep into the anus to cut off the connected elastic line. This operation is very troublesome and the efficiency is greatly reduced. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a disposable hemorrhoid ligation stapler cutting and firing assembly, aiming to improve the problems raised in the above background technology.

[0005] An embodiment of the present application provides a disposable hemorrhoid ligation stapler cutting and firing assembly including a stapler assembly and a cutting assembly.

[0006] The stapler assembly comprises a hemorrhoidal ligation stapler body, a firing rod and a transmission rod. The firing rod is located at the end of the hemorrhoidal ligation stapler body, and the transmission rod is connected to one side of the firing rod.

[0007] The wire cutting assembly includes a gun head body, a wire cutting rod, a wire harness and a cutting knife. The gun head body is installed at the end of the hemorrhoid ligation stapler body, the wire cutting rod is rotatably arranged at the bottom of the gun head body, the wire cutting rod is movably connected to the transmission rod, the cutting knife is arranged at the end of the wire cutting rod, and the cutting knife extends into the wire harness.

[0008] In a specific embodiment, a rotating shaft is rotatably provided through the tangent rod, and the rotating shaft is fixedly connected to the bottom of the gun head body.

[0009] In the above implementation process, a rotating shaft is provided to connect the bottom of the gun head body, so as to connect and support the rotation of the tangent rod.

[0010] In a specific embodiment, a notch is formed at one end of the tangent rod away from the cutting knife, and the end of the transmission rod is bent and extends into the notch.

[0011] In the above implementation process, by providing the notch, when the transmission rod moves together with the firing rod, it can contact the inner wall of the notch and pull the thread cutting rod to rotate.

[0012] In a specific embodiment, the length of the notch is much larger than the bending length of the end of the transmission rod.

[0013] In the above implementation process, by setting the length of the slot size much larger than the bending length of the end of the transmission rod, the firing rod pulls the wire drawing rod inside the main body of the gun head so that the elastic wire at the end is fired and ligated to the hemorrhoids. The firing rod drives the transmission rod to move at the same time. When the elastic wire is fired and ligated to the hemorrhoids, the bent end of the transmission rod moves in the slot and the inner wall of the slot begins to squeeze and drive the tangent rod. As the elastic wire is tightened, the tangent rod rotates, and the tangent rod drives the cutting knife to start cutting the elastic wire, thereby realizing the ligation, tightening and cutting in one step.

[0014] In a specific embodiment, a groove is formed at the end of the cutting rod, and the cutting knife is fixedly connected to the inner wall of the groove.

[0015] In a specific embodiment, the cable tie sleeve is provided with a cutting opening, and the cutting knife body is located in the cutting opening.

[0016] In the above implementation process, by arranging the cutting knife body to be located in the cutting opening, the cutting knife squeezes and cuts the excess part of the elastic line close to the inner wall of the cutting opening, so as to achieve stable cutting.

[0017] In a specific embodiment, a sealing ring joint is provided at one end of the gun head body.

[0018] In the above implementation process, a sealing ring joint is provided to connect the main body of the hemorrhoid ligation stapler to the trachea.

[0019] In a specific embodiment, a gas nozzle protection cover is provided at the other end of the gun head body.

[0020] In the above implementation process, an air nozzle protection cover is provided to seal the hemorrhoid suction chamber when not in use.

[0021] Beneficial effects: The present application provides a disposable hemorrhoid ligation stapler cutting and firing assembly, which includes a hemorrhoid ligation stapler body, a firing rod, a transmission rod, a gun head body, a tangent rod, a wire sleeve and a cutting knife. The firing rod is used to fire the elastic wire rod on the gun head body to fire the elastic wire. At the same time, the firing rod drives the transmission rod to move, and the transmission rod drives the tangent rod to rotate, so that the cutting knife at the end of the tangent rod can cut the elastic wire connecting part in the wire sleeve, thereby realizing the continuous action of ligation, tightening and cutting, avoiding re-cutting, and improving practicality and efficiency.

[0033] The tangent rod 220 is provided with a rotating shaft 221 for rotation, and the rotating shaft 221 is fixedly connected to the bottom of the gun head body 210. The rotating shaft 221 is connected to the bottom of the gun head body 210 to connect and support the tangent rod 220 for rotation.

[0034] In a specific embodiment, a slot 222 is provided at one end of the cutting rod 220 away from the cutting knife 250, the end of the transmission rod 130 is bent, and the end of the transmission rod 130 extends into the slot 222. By providing the slot 222, when the transmission rod 130 moves with the firing rod 120, it can contact the inner wall of the slot 222 to pull the cutting rod 220 to rotate.

[0035] It should be noted that a slot 222 is provided at one end of the tangent rod 220 away from the cutting knife 250, and the end of the transmission rod 130 is bent, and the end of the transmission rod 130 extends into the slot 222. By providing the slot 222, when the transmission rod 130 moves with the firing rod 120, it can contact the inner wall of the slot 222 to pull the tangent rod 220 to rotate.

[0036] It should be noted that the length of the slot 222 is much larger than the bending length of the end of the transmission rod 130. By setting the length of the slot 222 to be much larger than the bending length of the end of the transmission rod 130, the firing rod 120 pulls the wire rod inside the gun head body 210 so that the elastic line at the end is fired and ligated to the hemorrhoids. The firing rod 120 also drives the transmission rod 130 to move. When the elastic line is fired and ligated to the hemorrhoids, the bent end of the transmission rod 130 moves in the slot 222 and the inner wall of the slot 222 begins to squeeze and drive the tangent rod 220. As the elastic line is tightened, the tangent rod 220 rotates, and the tangent rod 220 drives the cutting knife 250 to start cutting the elastic line, thereby realizing the ligation, tightening and cutting in one step.
