Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a hemorrhoid ligation device which can be disconnected by one hand. Background Art

[0002] Hemorrhoids, a chronic disease caused by varicose veins at the bottom of the anorectum and anal mucosa, has long troubled many patients. Among the many surgical treatment methods, mixed hemorrhoid external ligation, hemorrhoidal circumcision (PPH), partial hemorrhoidal circumcision (TSH) and hemorrhoidal ligation devices have their own characteristics. Among them, hemorrhoidal ligation devices have been widely used in clinical practice. The working principle is to accurately insert the elastic line into the root of the hemorrhoids through precise instrument design, then tighten the knot, and then manually cut off the excess elastic line, so that it can effectively block blood circulation and make the hemorrhoids necrotize and fall off due to ischemia. However, the existing hemorrhoidal ligation device has a complex structure and many accessories. It may increase the difficulty and time of the surgical operation, and have certain requirements on the doctor's operating skills and experience. At the same time, this may also increase the cost of the operation, which is not conducive to the promotion and use in some areas with limited medical resources. Secondly, there are indeed some inconveniences regarding the need for the assistance of the doctor's assistant or the use of the built-in blade to cut the elastic line during the line breaking process. The need for assistant assistance may increase the manpower cost of the operation, and may also increase the risk and uncertainty of the operation. Although the use of built-in blades can reduce dependence on assistants, when pressing the external button, the elastic line needs to be kept tightened, which has a certain impact on the stability and accuracy of the surgical operation. Therefore, it needs to be improved and optimized. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a hemorrhoid ligation device that can be disconnected with one hand, which has the advantages of strong applicability and simple operation.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hemorrhoid ligation device with one-handed disconnection capability, comprising a body, a handle fixedly mounted on the bottom of the body, a straw fixedly mounted on the left side of the body, a fixed ring block and a joint fixedly sleeved on the outer wall of the straw, a U-shaped block fixedly mounted on the right outer wall of the fixed ring block, a cutting blade fixedly mounted on the inner wall of the U-shaped block, and a negative pressure joint fixedly mounted on the bottom of the handle.

[0005] As a preferred technical solution of the utility model, a circular groove 1 is provided at the left end of the straw, and a circular groove 2 and a circular groove 3 are provided on the outer wall of the straw, and the circular groove 2 and the circular groove 3 are both connected to the circular groove 1.

[0006] As a preferred technical solution of the utility model, the U-shaped block is installed on the outer wall of the fixed ring block at an angle of 60 degrees, and there are four U-shaped blocks distributed in a circular array.

[0007] As a preferred technical solution of the utility model, the cutting blade is U-shaped, and the number of the cutting blades is consistent with the number of U-shaped blocks.

[0008] As an optimal technical solution of the utility model, the number of circular groove one, circular groove two, and circular groove three are all four, the circular groove two is arranged between the straw and the circular groove three, and the groove hole diameters of circular groove one, circular groove two, and circular groove three are the same.

[0009] As a preferred technical solution of the utility model, the inner diameter of the cutting blade is greater than the diameter value of the second circular groove.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a hemorrhoid ligation device that can be disconnected with one hand, comprising a body 1, a handle 2 is fixedly installed at the bottom of the body 1, a straw 3 is fixedly installed on the left side of the body 1, a fixed ring block 7 and a joint 10 are fixedly sleeved on the outer wall of the straw 3, a U-shaped block 8 is fixedly installed on the right outer wall of the fixed ring block 7, a cutting blade 9 is fixedly installed on the inner wall of the U-shaped block 8, and a negative pressure joint 11 is fixedly installed at the bottom of the handle 2.

[0021] The position of the cutting blade 9 is fixed by setting the U-shaped block 8 to ensure its stability and prevent it from moving due to external force or operation. When the elastic line ligation operation is completed and the excess elastic rope needs to be cut, the staff can hold the instrument body 1 with the right hand and pull the elastic line with the left hand to complete the action of tying the hemorrhoids and tightening the elastic line. The elastic line is pressed down by the index finger of the left hand to form an angle with the embedded cutting blade 9 to complete the line cutting. Through this setting, the surgical process becomes more efficient and convenient. The staff does not need to use additional tools or perform complicated operations to cut the elastic rope. They only need to simply pull the elastic rope to cut the line. This not only saves time, but also reduces the difficulty and complexity of operations during the operation.

[0022] The doctor first connects the negative pressure device to the negative pressure connector 11, ties a knot in the elastic rope and puts it on the outer wall of the suction tube 3, one end of the knot of the elastic rope enters the circular groove 2 5 and passes through the circular groove 3 6, then aims the suction tube 3 at the hemorrhoids, starts the negative pressure device, sucks the hemorrhoids, and then pulls the elastic rope to ensure that the elastic line can accurately fit into the root of the hemorrhoids. The doctor then pulls the elastic rope in the opposite direction, and the elastic rope will come into contact with the cutting blade 9 and be cut off.

[0023] A circular groove 1 4 is provided at the left end of the straw, and a circular groove 2 5 and a circular groove 3 6 are provided on the outer wall of the straw, and the circular groove 2 5 and the circular groove 3 6 are both connected to the circular groove 1 4 .

[0024] By tying a knot in the elastic cord and putting it on the outer wall of the straw 3, one end of the knot of the elastic cord enters the circular groove 2 5 and passes through the circular groove 3 6, so that the elastic cord can be firmly fixed on the straw 3 without the need for an additional fixing device, thereby simplifying the surgical steps and improving the efficiency and accuracy of the surgery.

[0025] The U-shaped block 8 is installed on the outer wall of the fixed ring block 7 at an inner angle of 60°. There are four U-shaped blocks 8 distributed in a circular array.

[0026] By installing the U-shaped block 8 at an angle, the elastic rope can generally reduce the resistance during the cutting process, making the cutting process smoother, thereby improving work efficiency.

[0027] The cutting blades 9 are U-shaped, and the number of the cutting blades 9 is the same as the number of the U-shaped blocks 8 .

[0028] By providing the cutting blade 9, the sharp edge of the cutting blade 9 can easily cut the elastic cord, which not only improves the surgical efficiency but also reduces the damage to the surrounding tissues caused by the friction and resistance generated during the cutting process.

[0029] Among them, the number of circular groove one 4, circular groove two 5, and circular groove three 6 are all four, and circular groove two 5 is arranged between the straw 3 and circular groove three 6, and the groove hole diameters of circular groove one 4, circular groove two 5, and circular groove three 6 are the same.

[0030] By providing a plurality of circular grooves 1 4 , 2 5 and 3 6 , multiple hemorrhoids can be ligated, thereby greatly shortening the operation time, which not only reduces the workload of the doctor, but also allows the patient to complete the operation faster and reduce the waiting time on the operating table.

[0031] The inner diameter of the cutting blade 9 is greater than the diameter of the circular groove 5 .

[0032] Since the diameter of the circular groove 25 is smaller than the inner diameter of the cutting blade 9, a certain movable space is provided in the elastic rope, and the movable space allows the blade to flexibly perform cutting action when necessary without being excessively restricted by the circular groove 25.

[0033] The working principle and use process of this utility model:

[0034] The doctor first connects the negative pressure device to the negative pressure connector 11, ties a knot in the elastic rope and puts it on the outer wall of the suction tube 3, one end of the knot of the elastic rope enters the circular groove 2 5 and passes through the circular groove 3 6, then aims the suction tube 3 at the hemorrhoids, starts the negative pressure device, sucks the hemorrhoids, and then pulls the elastic rope to ensure that the elastic line can accurately fit into the root of the hemorrhoids. The doctor then pulls the elastic rope in the opposite direction, and the elastic rope will come into contact with the cutting blade 9 and be cut off.
