Description

TECHNICAL FIELD

[0001] The present application relates to a surgical treatment device for thrombotic external hemorrhoids, in particular to a thrombotic external hemorrhoid thrombectomy device. BACKGROUND

[0002] Thrombotic external hemorrhoids are generally formed on the skin beside the anus, generally dark purple nodules in circular or oval shape, in a bulging state higher than the surrounding skin. One treatment method for thrombotic external hemorrhoids is to remove the thrombus by surgery. The thrombectomy process is to first break the skin with a blade, and then squeeze from both sides to squeeze out the thrombus.

[0003] In some cases, the thrombus is severely adhered to the outer skin, and even if the skin is broken, it is not easy to squeeze out the thrombus, at which time a larger incision is needed to use other instruments to peel or separate internally, causing greater harm to the patient. In some cases, the bulge of thrombotic external hemorrhoids is not very prominent, and it is not convenient to squeeze the thrombus from both sides, not only not easy to squeeze out the thrombus, but also easy to cause the thrombus to break, resulting in incomplete thrombectomy.

[0004] In addition, thrombotic external hemorrhoids are an emergency of anorectal surgery, and the main symptom is obvious pain. The best operation time is within 72 hours, but it is difficult to implement immediate hospitalization or outpatient surgery, and a simple and effective thrombectomy device is needed to simplify the thrombectomy operation process.

[0010] The clamping member comprises a ring-shaped base; the base is sleeved on the outer periphery of the lower end of the first tube body; the lower end of the base is provided with two insertion slots which are opposite to each other; an insertion plate is slidably inserted into each insertion slot, and the insertion plate is used to be inserted to the lower side of the embolus of the thrombotic external hemorrhoids by abutting against the root of the outer skin of the thrombotic external hemorrhoids, so as to lift the embolus upward.

[0011] Preferably, the lower end of the first tube body is formed with an outwardly protruding stopper to prevent the base from being detached from the first tube body.

[0012] Preferably, the edge of the lower end of the first tube body is formed with a notch, and when the lower end of the first tube body is adsorbed together with the outer skin at the head end of the thrombotic external hemorrhoids, part of the outer skin is embedded in the notch, so that the combination of the outer skin and the first tube body is more firm.

[0040] Hereinafter, the thrombotic external hemorrhoid removing device of the present application will be described in detail with reference to the accompanying drawings.

[0041] The thrombotic external hemorrhoid removing device of the present application includes a main body 10, a piston member 20, a skin breaking member 30, and a clamping member 40.

[0042] The main body 10 includes a first tube body 11 and a second tube body 12; the second tube body 12 is formed at the side of the first tube body 11, and the first tube body 11 and the second tube body 12 are formed in a Y-shaped structure.

[0043] The skin breaking member 30 includes a rod body 31 which is slidably inserted into the first tube body 11; the upper end of the rod body 31 is exposed above the first tube body 11, and the lower end of the rod body 31 is inserted into the inside of the first tube body 11 from the upper end of the first tube body 11; a sharp blade 32 is formed at the lower end of the rod body 31, and the blade 32 is used to form a skin breaking opening by being inserted from the upper end of the thrombotic external hemorrhoid; and the outer periphery of the rod body 31 and the upper end of the first tube body 11 are formed in airtightness. The upper end of the rod body 31 is formed with a stopper 33.

[0044] ​​​​​​​The upper end of the first tube body 11 is formed with a cover plate 15, and a through hole 16 is formed in the middle of the cover plate 15. The rod body 31 of the skin breaking member 30 is inserted into the through hole 16. A sealing ring (not shown in the figure) is installed in the through hole 16 to form a seal between the through hole 16 and the rod body 11.

[0045] The lower end of the first tube body 11 is formed with an outwardly protruding stop edge 13 to prevent the base 41 from being detached from the first tube body 11.

[0046] The edge of the lower end of the first tube body 11 is formed with a notch 14. When the lower end of the first tube body 11 is attracted to the skin at the head end of the thrombotic external hemorrhoids, part of the skin is embedded in the notch 14, so that the combination of the skin and the first tube body 11 is more firm, and especially when the skin is twisted, the skin is not easy to slide with the first tube body 11.

[0047] The piston member 20 includes a piston rod 22 and a piston head 23. The piston head 23 is formed at the lower end of the piston rod 22. The piston member 20 is slidably inserted into the second tube body 12. The piston head 23 is located inside the second tube body 12 and is formed in airtight with the inner wall of the second tube body 12. The upper end of the piston rod 22 is exposed above the second tube body 12. When it is partially pulled out of the second tube body 12, the piston member 20 forms a negative pressure in the second tube body 12 and the first tube body 11 connected with the second tube body 12, so as to tightly attract the skin at the head end of the thrombotic external hemorrhoids to the lower end of the first tube body 11 and part of the skin enters into the lower end of the first tube body 11. Thus, the relative movement between the skin of the thrombotic external hemorrhoids and the thrombus of the thrombotic external hemorrhoids can be formed by manipulating the first tube body 11, so that the adhesion between the skin and the thrombus is reduced.

[0048] The upper end of the piston rod 22 is fixed with a nut 21 through a connecting rod 24. The outer periphery of the upper end of the second tube body 12 is formed with external threads. The nut 21 of the piston rod 22 is combined on the external threads of the second tube body 12 to keep the position of the piston head 23 at the lower end of the piston rod 22 in the second tube body 12 by the external threads.

[0049] The clamping member 40 includes a ring-shaped base 41. The base 41 is sleeved on the outer periphery of the lower end of the first tube body 11. The lower end of the base 41 is provided with two insertion slots 43a which are opposite to each other. An insertion plate 43 is slidably inserted into each insertion slot 43a. The insertion plate 43 is used to be inserted into the lower side of the thrombus of the thrombotic external hemorrhoids to lift the thrombus upward by abutting against the root of the skin of the thrombotic external hemorrhoids.

[0050] The two insertion slots 43a can be formed as dovetail slots.

[0051] The edge of the end of each insertion plate 43 inserted into the base 41 is formed with an inclined surface to facilitate the insertion into the lower side of the thrombus of the thrombotic external hemorrhoids.

[0052] The upper end of the base 41 is formed with an end plate 42, and the middle part of the end plate 42 is formed with a socket 44, into which the lower end of the first tube 11 is inserted.

[0053] In use, first the clamping member is slid upward to expose the lower end of the first tube, and the lower end of the first tube is abutted against the epidermis of the upper end of the thrombotic external hemorrhoids, then the piston member is partially pulled out to generate negative pressure in the first tube, so that the epidermis is partially sucked into the lower end of the first tube; then the first tube is operated to rotate or swing back and forth, so that the adhesion between the epidermis and the thrombus is reduced. Next, the clamping member is slid downward, and the plug plate is inserted below the thrombus while the thrombotic external hemorrhoids are kept being pulled upward by the first tube, so that the thrombus is lifted up with the epidermis below. Then the skin-breaking member is pressed to cut the epidermis partially sucked in the first tube, and the whole device is pulled upward as a whole, and under the pushing of the plug plate and the suction of the negative pressure, the thrombus can be easily pulled out from the skin-breaking opening. Then the piston member is pushed back, and the whole device is removed, and the pulled-out thrombus and the skin-breaking opening are cleaned, and the skin-breaking opening is applied with medicine.

The materials, methods, and examples in this application are illustrative only and not intended to be limiting.
