Description

Dilator for hemorrhoid operation

Technical Field

The present disclosure relates to the technical field of medical devices, and in particular, to a dilator for hemorrhoid surgery.

Background

Hemorrhoids are a common anorectal disease including internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. For severe internal hemorrhoids, surgical treatment is often performed by ligation, i.e. by blocking the blood supply to the base of the hemorrhoid by ligating it, which causes anoxic necrosis of the hemorrhoid. The hemorrhoid is removed and the wound surface basal part is repaired simultaneously, and when the hemorrhoid is removed, new granulation tissues rapidly fill the wound surface to achieve the cure purpose.

In the ligation operation process, the hemorrhoids are sleeved by an operation wire, but the internal hemorrhoids have deeper growth positions, the operation vision is enlarged by using a dilator, the prior dilator is often automatically displaced under the influence of muscle movement of a patient when in use, and a doctor is required to hold and fix the operation, so that inconvenience is brought to the operation.

In order to solve the technical problems, the utility model discloses an expander for hemorrhoid surgery, which comprises an expansion guide component, wherein the middle part of the expansion guide component is semicircular, the first end is in a quarter sphere shape, and the second end is in a half horn shape; the handle is fixed at one end of the handle outside the second end of the expansion guide component; the guide tube is arranged inside the expansion guide component and the handle and extends outwards from the first end of the expansion guide component and one side of the handle away from the expansion guide component; and the expansion bag is connected with one end of the catheter close to the expansion guide component. According to the hemorrhoid operation dilator disclosed by the utility model, the dilating bag is matched with the dilating guide component, so that the dilator can be stably placed in the anal canal of a patient without being held and fixed by a doctor, and a lighting function can be attached, so that the doctor can keep a stable operation view when performing an operation.

Fig. 1 illustrates a block diagram of a dilator for hemorrhoid surgery according to an embodiment of the present disclosure. As shown in fig. 1, the hemorrhoid surgical dilator includes:

an expansion guide member 110, the middle of which is semi-circular, the first end 111 is one-fourth sphere, and the second end 112 is semi-bell mouth;

a handle 120, wherein one end of the handle 120 is fixed outside the second end 112 of the expansion guide component;

a catheter 130, the catheter 130 being disposed inside the expansion guide member 110 and the handle 120 and extending outwardly from the expansion guide member first end 111 and the end of the handle 120 remote from the expansion guide member 110;

a dilatation balloon 140 connected to an end of the catheter 130 proximal to the dilatation guide member 110.

The hemorrhoid surgical dilator is used in the cases of hemorrhoid surgery and the like which need to provide visual field for the surgery through the dilation affected part, taking hemorrhoid surgery as an example, in hemorrhoid surgery, firstly, the dilation balloon 140 and the dilation guide member 110 of the hemorrhoid surgical dilator are sequentially put into the anal canal of a patient, then, liquid is injected into the dilation balloon 140 along the catheter 130 until the dilation balloon 140 is fully inflated, the anal canal is supported, and then, a doctor can perform hemorrhoid ligation operation. The first section 111 of the expansion guide member is one-quarter spherical and has a rounded outer surface for ease of insertion into the patient's affected area. The second end 112 of the expansion guide component is semi-horn-shaped, and can be clamped outside an anal canal when in use, so that the expander is convenient to fix in an auxiliary manner.

According to an embodiment of the present disclosure, the balloon 140 is spherical when in an expanded state. Fig. 2 illustrates a schematic view of an operating state of a dilator for hemorrhoid surgery according to an embodiment of the present disclosure. As shown in fig. 2, after the expansion bladder 140 and the expansion guide member 110 are introduced into the anal canal of the patient, a liquid such as physiological saline is injected into the catheter 130 using a syringe, and the expansion bladder 140 is inflated as the liquid injection starts, and the inflation is performed to a spherical shape, thereby achieving the purpose of supporting the anal canal to open the surgical field.

According to an embodiment of the present disclosure, the catheter 130 is provided with a butt joint 131 near one end of the handle. As shown in fig. 1, the docking head 131 has a conical shape, wherein a smaller diameter end is connected to the catheter 130, and the other end is used for docking a syringe or other fluid infusion tool. Further, a sealing ring or a sealing gasket is arranged on the inner side of the butt joint to prevent liquid leakage when the liquid is poured into the guide pipe.

According to an embodiment of the present disclosure, the hemorrhoid surgical dilator further comprises: the illuminating lamp 150 comprises a lamp cap 151 and a buckle 152, wherein the lamp cap 151 is arranged in a circular ring of the buckle 152, and the buckle 152 is detachably connected with the second end 112 of the expansion guide component. When hemorrhoid operation is carried out, a doctor needs to provide illumination for the inside of the anal canal so as to carry out operation, and the illuminating lamp is arranged on the expander, so that the illumination direction is the same as the sight direction of the doctor, the operation vision is enabled to be clearer, the illumination blind area is reduced, and the operation is carried out. Further, the lamp cap 151 uses LED lamp beads, and is powered by a lithium battery or a button battery. Further, the bottom of the buckle 152 is C-shaped, and the diameter of the opening is slightly smaller than the thickness of the second end 112 of the expansion guide member, for example, the thickness of the second end 112 is 0.5mm, the diameter of the opening of the buckle 152 is 0.4mm, and when the illumination lamp is installed, the second end 112 is placed into the opening of the buckle 152 to complete the fixation of the illumination lamp 150.

According to an embodiment of the present disclosure, the outer surface of the handle is provided with anti-slip stripes 121. The anti-slip stripes may be in the shape of regular depressions or protrusions provided on the outer side surface of the handle 120, or may be in the shape of a bar or ring of plastic or rubber material mounted on the outer side surface of the handle 120.

The foregoing description is only of the preferred embodiments of the present disclosure and description of the principles of the technology being employed. It will be appreciated by those skilled in the art that the scope of the utility model referred to in this disclosure is not limited to the specific combination of features described above, but encompasses other embodiments in which any combination of features described above or their equivalents is contemplated without departing from the inventive concepts described.
