Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for treating oral skin flap congestion with leeches. Background Art

[0002] After microvascular anastomosis, flap venous congestion is a precursor to flap venous obstruction. If not promptly intervened, it can rapidly develop into tissue necrosis, leading to flap repair failure. Traditionally, leech therapy, as a classic treatment method, has been widely used to treat flap venous congestion on surfaces such as the limbs. However, its application in the treatment of oral flap congestion is significantly limited.

[0003] The oral cavity, as a relatively closed and sensitive environment, presents unique requirements for leech therapy. Firstly, the oral cavity's confined space makes it easy for leeches to stray into the airway or digestive tract, potentially leading to serious complications. Secondly, many patients experience fear and aversion to leeches entering their mouths, a psychological discomfort that limits its application.

[0004] More importantly, the market currently lacks a dedicated leech-assisted device for treating oral flap congestion. Doctors often struggle to effectively grasp and secure the leech during treatment, which not only increases the difficulty of treatment but also reduces safety and patient comfort.

[0005] In order to solve the above problems, the utility model provides an auxiliary device for treating oral skin flap congestion with leeches. Utility Model Content

[0027] like Figure 1 As shown in FIG, the auxiliary device for treating intraoral skin flap congestion with leeches mainly consists of three parts: a tube 1, a cap 2 and a piston rod 3.

[0028] like Figure 2 As shown, the cylinder 1c is designed to be cylindrical in shape and is made of a transparent material (such as medical-grade plastic) to facilitate observation of the situation inside the cylinder; one end of the cylinder 1c is open for installing the cap 2, and the other end is used to install the piston 3a; at the top of the cylinder 1c, that is, the end connected to the cap 2, an external cylinder thread 1a is provided to cooperate with the internal cap thread 2a of the cap 2 to achieve a detachable fixed connection; in addition, a wing 1b for easy holding is provided on the outer side of the bottom of the cylinder 1c to facilitate the doctor to hold the assistive device stably during operation.

[0029] like Figure 3 As shown, the cap body 2c is designed in the shape of an open cylindrical tube and is also made of transparent material; the inner side of the opening of the cap body 2c is provided with a cap internal thread 2a that cooperates with the tube external thread 1a to ensure a stable connection between the cap 2 and the tube 1; on the bottom surface of the cap body 2c, there is an inlet 2b for sucking in leeches, and the diameter of the inlet 2b matches the diameter of the leech body to facilitate the grasping of the leech; in addition, the design of the inlet 2b is similar to the nipple of a syringe, which is convenient for aligning with the tail of the leech for suction.

[0030] like Figure 4As shown, the piston rod 3 consists of a piston 3a and a rod 3b; the piston 3a is airtightly installed in the cylinder 1c from the other end of the cylinder 1c, and a sealing ring made of elastic material is provided between the piston 3a and the inner wall of the cylinder 1c to ensure the airtightness of the piston during movement; the rod 3b is arranged on the outside for pushing and pulling the piston 3a; at the outer end of the rod 3b, a hook 3d is provided, and the hook 3d is fixedly connected to the rod 3b through a hook seat 3c, and the cross-sectional size of the hook seat 3c is smaller than the cross-sectional size of the rod 3b to reduce potential damage to the tissues in the oral cavity; in addition, a cover 3e for covering the hook 3d can be detachably connected to the outer end of the rod 3b, and the cover 3e consists of a cylindrical cover body and a flat plate at the bottom, and the upper opening of the cover body is threadedly connected to the rod 3b so that the hook 3d can be covered when it is not needed.

[0031] Working principle and usage of the leech auxiliary device for treating oral flap congestion:

[0032] To use this assistive device, first tighten cap 2 onto barrel 1c, ensuring inlet 2b is aligned with the leech's tail. Then, by pulling rod 3b of piston rod 3, piston 3a moves backward within barrel 1c, creating negative pressure and drawing the leech into barrel 1c. Because the diameter of inlet 2b matches the leech's body, the leech can be easily grasped without slipping.

[0033] After the leech is sucked into the cylinder 1c, the piston rod 3 is removed from the cylinder 1c, the cover 3e is removed, and the piston rod 3 is placed upside down in the cylinder 1c. The tail of the leech is hooked with a hook 3d. The tip of the hook 3d is provided with a barb, similar to a fishhook, so that the leech can be fixed in the cylinder 1c to limit its uncontrolled movement.

[0034] Remove cap 2 and aim the leech-attached device at the congested area of the oral flap, ensuring the opening of the barrel 1c rests firmly against the flap treatment area. This allows the leech to precisely adhere to the congested area and deliver treatment. The patient then bites down on barrel 1c. Because barrel 1c and cap 2 are both made of transparent material, the leech's activity and the improvement of the congested area can be clearly observed.

[0035] After treatment, remove the device and leech from the mouth and dispose of the leech and device properly. Since the device is designed to be disposable, it should be thrown away after use, ensuring cleanliness and hygiene.

[0036] This leech aid for treating oral flap congestion effectively solves various problems existing in traditional leech therapy when applied in the oral cavity. It is simple to use and easy to operate, and can easily grasp and firmly fix the leech, avoiding the risk of the leech accidentally entering the airway or digestive tract. At the same time, the design of the cylinder and cap made of transparent materials and the detachable hook and cover improves the safety of treatment and the comfort of the patient. In addition, this aid also adopts the design concept of disposable materials to ensure the cleanliness and hygiene of the treatment process and the safety of the patient.
