Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a structure for a slanted push-up ligation device. Background Technology

[0002] Currently, most hemorrhoid ligation devices used in clinical practice are of the straight-push type. After the hemorrhoid is sucked in by negative pressure through a suction tube, a rubber band is pushed to the root of the hemorrhoid using a pusher tube to achieve ligation. However, existing straight-push hemorrhoid ligation devices have the following drawbacks: First, straight-push hemorrhoid ligation devices are only suitable for direct suction. When the hemorrhoid is misaligned or the suction is unstable, the pushed rubber band is not easy to accurately reach the target area, resulting in poor adaptability. Second, straight-push hemorrhoid ligation devices are difficult to conform to the curved surface of the intestine, easily leading to ligation deviation or failure, indicating insufficient conformity to the intestine. Third, when there are many hemorrhoids in irregular positions, the doctor needs to frequently adjust the angle, increasing the difficulty of the surgical procedure, making the surgery more challenging.

[0003] Designing a simple, obliquely pushing bandage structure that can push the rubber ring at an angle is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a simple structure of a slanted push bandage that can push the rubber ring at an angle, so as to solve the above-mentioned problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a slanted pusher bandage structure, including: a housing, a suction tube, a pushing assembly, a tension spring, a trigger, and a bandage ring;

[0006] The interior of the housing has a guide and receiving part;

[0007] A straw assembly includes a straw head and a straw body connected from front to back, the straw body being connected to a housing; the straw head includes a straw end piece and a straw head connector connected from front to back; the rear end of the straw head connector is connected to the straw body; the central axis of the straw end piece is inclined relative to the central axis of the straw head connector.

[0008] The pushing assembly includes a pushing component, an intermediate component, and a driving component connected sequentially from front to back; the pushing component includes a pushing tube and a pushing connector connected from front to back; the driving component includes a driving connector and a driving body connected from front to back; the front end of the intermediate component is connected to the pushing connector, and the rear end of the intermediate component is connected to the driving connector; the driving body is inserted into the guide receiving portion, and the driving body can move within the guide receiving portion; the pushing tube is sleeved on the outer peripheral surface of the straw end piece; the central axis of the pushing tube is inclined relative to the extension direction of the pushing connector, and the extension direction of the pushing connector is parallel to the direction of the central axis of the straw body; the angle formed between the central axis of the straw end piece and the central axis of the straw end connector is equal to the angle formed between the central axis of the pushing tube and the extension direction of the pushing connector;

[0009] The front end of the tension spring is connected to the drive body, and the rear end of the tension spring is connected to the housing;

[0010] The trigger component is movably mounted on the housing;

[0011] The ferrule is fitted onto the straw end piece, and the ferrule is positioned in front of the push tube;

[0012] When the trigger pushes the drive body of the drive component to move, the drive body moves forward in the guide receiving part, and the drive component drives the push component to move forward through the intermediate component, so that the push tube moves forward along the axial direction of the suction tube end piece.

[0013] Preferably, there are two guide receiving parts, which are arranged opposite to each other; the two ends of the drive body are respectively inserted into the two guide receiving parts.

[0014] Preferably, the guide receiving part is a guide groove provided on the housing.

[0015] Furthermore, the horizontal height of the front end of the guide groove is lower than the horizontal height of the rear end of the guide groove.

[0016] Preferably, the upper end of the trigger member has two trigger protrusions with a gap between them; the trigger protrusions contact the drive body and are used to push the drive body to move; the drive body has two limiting protrusions located between the two trigger protrusions.

[0017] Preferably, the intermediate component is a downwardly protruding arc-shaped structure; the pushing connector is a downwardly protruding arc-shaped structure; and the driving connector is a downwardly protruding arc-shaped structure.

[0018] Preferably, the angle formed between the central axis of the straw end piece and the central axis of the straw head connector is in the range of 100° to 170°.

[0019] As described above, the obliquely pushing bandage structure of this utility model has the following beneficial effects:

[0020] In this invention, the obliquely pushing ligation device is designed so that the doctor inserts the suction head of the suction tube into the patient's anus and aspirates the hemorrhoids. Because the central axis of the suction tube end is inclined relative to the central axis of the suction tube head connector, the suction head can fit more closely to the intestinal wall. Pressing the trigger extends the tension spring, which in turn pushes the drive body of the drive component to move forward within the guide receiving part. The drive component, through the intermediate component, drives the pushing component forward, causing the pushing tube to move forward along the axial direction of the suction tube end. The pushing tube can obliquely push the ligation ring, precisely pushing it to the root of the hemorrhoids. Using an oblique pushing motion allows the pushing tube to fit more closely to the intestinal wall, improving the accuracy and stability of the ligation and reducing the difficulty of the surgical procedure.

[0052] like Figures 1 to 8 As shown, the obliquely pushable bandage structure of this embodiment includes: a housing 100, a suction tube 200, a pushing assembly 300, a tension spring 400, a trigger 500, and a bandage ring 600;

[0053] The housing 100 has a guide receiving part 110 inside;

[0054] The straw assembly 200 includes a straw body 210 and a straw head 220 connected to the front end of the straw body 210. The straw body 210 is connected to the housing 100. The straw head 220 includes a straw head connector 221 and a straw end piece 222. The rear end of the straw head connector 221 is connected to the straw body 210, and the front end of the straw head connector 221 is connected to the rear end of the straw end piece 222. The central axis of the straw head connector 221 is collinear with the central axis of the straw body 210, and the central axis of the straw end piece 222 is inclined relative to the central axis of the straw head connector 221. The front end of the straw body 210 extends out from the inside of the housing 100. The straw end piece 222 and the straw head connector 221 are integrally formed.

[0055] The pushing assembly 300 includes a pushing component 310, an intermediate component 320, and a driving component 330 connected sequentially from front to back. The pushing component 310 includes a pushing tube 311 and a pushing connector 312 connected to the rear end of the pushing tube 311. The driving component 330 includes a driving body 331 and a driving connector 332 connected to the front end of the driving body 331. The front end of the intermediate component 320 is connected to the pushing connector 312, and the rear end of the intermediate component 320 is connected to the driving connector 332. The driving component 330 is located inside the housing 100, and the driving body 331 is inserted into the guide receiving portion. In 110, the drive body 331 can move within the guide receiving part 110; the intermediate component 320 extends from the inside of the housing 100; the push tube 311 is sleeved on the outer peripheral surface of the straw end piece 222; the central axis of the push tube 311 is inclined relative to the extension direction of the push connector 312, and the extension direction of the push connector 312 is parallel to the central axis of the straw body 210; the angle A formed between the central axis of the straw end piece 222 and the central axis of the straw head connector 221 is equal to the angle C formed between the central axis of the push tube 311 and the extension direction B of the push connector 312;

[0056] The front end of the tension spring 400 is connected to the drive body 331, and the rear end of the tension spring 400 is connected to the housing 100.

[0057] The trigger component 500 is movably connected to the housing 100, and the trigger component 500 can rotate relative to the housing 100;

[0058] The 600 loop is fitted onto the straw end piece 222, and the 600 loop is positioned in front of the push tube 311;

[0059] When the trigger 500 pushes the drive body 331 of the drive component 330 to move, the drive body 331 moves forward in the guide receiving part 110, and the drive component 330 drives the push component 310 to move forward through the intermediate component 320, so that the push tube 311 moves forward along the axial direction of the suction tube end component 222.

[0060] In the oblique push ligator structure of this utility model, the doctor inserts the suction head 220 of the suction tube 200 into the patient's anus and absorbs the hemorrhoids. Because the central axis of the suction head 222 is inclined relative to the central axis of the suction head connector 221, the suction head 220 can fit more closely to the intestinal wall. Pressing the trigger 500 extends the tension spring 400, and the trigger 500 pushes the drive body 331 of the drive component 330 to move. The drive body 331 moves forward in the guide receiving part 110, and the drive component 330... The intermediate component 320 drives the pushing component 310 to move forward, causing the pushing tube 311 to move forward along the axial direction of the suction tube end piece 222. That is, the pushing tube 311 moves along the oblique track formed by the suction tube end piece 222. The pushing tube 311 can obliquely push the ligation ring 600, and the pushing tube 311 can accurately push the ligation ring 600 to the root of the hemorrhoid. By using the pushing tube 311 to obliquely push the ligation ring 600, the pushing tube 311 can fit more closely to the intestinal wall, improve the accuracy and firmness of the ligation, and reduce the difficulty of the surgical operation.

[0061] There are two guide receiving parts 110, which are arranged opposite to each other; both ends of the drive body 331 are respectively inserted into the two guide receiving parts 110. This structure enables the drive body 331 to move stably.

[0062] The guide receiving part 110 is a guide groove provided on the housing 100. The guide groove is easy to process and can provide a stable insertion space for the drive body 331. The guide receiving part 110 can also be a convex rail provided on the housing 100. The structure of the convex rail is not shown in the figure.

[0063] The horizontal height of the front end of the guide groove is lower than the horizontal height of the rear end of the guide groove. This structure ensures that when the trigger 500 is pressed, the trigger 500 pushes the drive body 331 of the drive component 330 in a downward and forward direction, which facilitates the trigger 500 pushing the drive body 331 of the drive component 330.

[0064] The upper end of the trigger member 500 has two trigger protrusions 510, with a gap between them. The trigger protrusions 510 contact the drive body 331 and are used to push the drive body 331 to move. The drive body 331 has two limiting protrusions 3311, located between the two trigger protrusions 510. When the trigger member 500 pushes the drive body 331 of the drive member 330, the drive body 331 may move in a left-right direction. The two limiting protrusions 3311, located between the two trigger protrusions 510, limit the range of left-right movement of the drive body 331.

[0065] The intermediate component 320 has a downwardly convex arc-shaped structure; the pushing connector 312 has a downwardly convex arc-shaped structure; and the driving connector 332 has a downwardly convex arc-shaped structure. Because the straw body 210 is a circular tube, and the intermediate component 320, the driving connector 332, and the pushing connector 312 all have downwardly convex arc-shaped structures, the gap between the straw body 210 and the pushing component 300 is small, making it less likely for intestinal tissue to be clamped by the straw body 210 and the pushing component 300.

[0066] The angle A formed between the central axis of the straw tip 222 and the central axis of the straw tip connector 221 ranges from 100° to 170°. The angle A between these two axes can be optimized according to clinical needs. In this embodiment, the angle A between the central axis of the straw tip 222 and the central axis of the straw tip connector 221 is 120°.

[0067] The outer diameter of the straw head 220 is 11-12 mm, and the inner diameter of the push tube 311 is 12-13 mm. The inner diameter of the push tube 311 is larger than the outer diameter of the straw head 220, and the difference between the inner diameter of the push tube 311 and the outer diameter of the straw head 220 is less than 2 mm, making the straw head 220 and the push tube 311 easy to manufacture. The push assembly 300 is made of medical-grade polymer material. The trigger 500 is hinged to the housing 100, forming a lever structure, and the upper part of the trigger 500 can contact the push tube 311. When the operator pushes the lower part of the trigger 500, the upper part of the trigger 500 drives the push tube 311 forward.

[0068] The suction tube 200 is used to adsorb hemorrhoids and form a negative pressure space to ensure that the hemorrhoids enter the adsorption cavity. The suction tube head 220 is angled, and the push tube 311 is installed on the suction tube end piece 222. The push tube 311 can move along the angle direction of the suction tube end piece 222. The suction tube end piece 222 plays a limiting role in the movement of the push tube 311.

[0069] The pushing tube 311 of the pushing component 310 of the pushing assembly 300 is disposed outside the straw end piece 222. The pushing tube 311 moves along the inclined track formed by the straw end piece 222. The driving body 331 of the pushing assembly 300 is connected to the tension spring 400. The tension spring 400 enables the pushing tube 311, which moves along the inclined path outside the straw end piece 222, to reciprocate.

[0070] When the front end of the push tube 311 contacts the ligature ring 600, the push tube 311 moves along the inclined path, thus pushing the ligature ring 600 along the inclined path; in this embodiment, the ligature ring 600 is a rubber ring.

[0071] The straw end piece 222 guides the operation of the push tube 311, enabling the push tube 311 to run stably along a preset angle.

[0072] The trigger 500 contacts the push tube 311, and the trigger 500 can drive the push assembly 300. Medical staff can press the trigger 500 to drive the push tube 311 of the push assembly 300 to move in an oblique path, so that the push tube 311 moves obliquely along the suction tube end piece 222, thus enabling the oblique pushing of the ligature ring 600.

[0073] When in use, the doctor places the suction tube 200 on the surface of the hemorrhoid and creates negative pressure. After the hemorrhoid enters the cavity of the suction tube 200, the doctor presses the trigger 500, and the tube moves along the inclined track formed by the suction tube body 210, pushing the ligation ring 600 obliquely to the root of the hemorrhoid to complete the ligation.

[0074] The oblique push ligator structure of this utility model pushes the tube 311 along a set angle track to push the ligating ring 600 obliquely, so that the ligating ring 600 can be ligated obliquely, improving the ligation accuracy and stability, and increasing the success rate of hemorrhoid treatment.

[0075] This invention's oblique push-and ligating device structure can achieve an oblique push-and ligating loop of 600, which allows for a closer fit to the root of the hemorrhoid, reducing displacement and dislodgement, and improving the success rate of surgery. The oblique push-and ligating device structure can handle irregular hemorrhoid positions or intestinal bends, reducing repeated surgical operations and adapting to complex anatomy. Using this oblique push-and ligating device structure, doctors can complete precise ligation with only routine procedures, shortening surgical time and simplifying operation. This oblique push-and ligating device structure achieves a more secure ligation effect, helping to reduce bleeding and recurrence rates, and reducing complications.

[0076] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0077] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
