Description

Technical Field

[0001] The utility model belongs to the technical field of mastitis lavage treatment, and in particular relates to a non-lactation mastitis lavage device. Background Art

[0002] Non-puerperal mastitis (NPM) is a group of benign, non-specific inflammatory diseases that occur in women during the non-lactating period, with unknown etiology, including mammary duct ectasia (MDE) / periductal mastitis (PDM) and granulomatous lobular mastitis (GLM). In recent years, the incidence of this disease has shown a clear upward trend. Although it is a group of benign diseases, conventional antibiotic treatment is not effective. It is still easy to relapse after multiple surgeries. Abscesses repeatedly rupture to form sinuses, fistulas or ulcers, which seriously affect the quality of life and cause harm to the physical and mental health of women. MDE / PDM can affect adult women of all ages, while GLM usually occurs in women of childbearing age, especially within 5 years after pregnancy. The main clinical manifestations of this type of disease are breast lumps, nipple inversion, nipple discharge, and breast pain. Breast lumps can develop into acute infections and form abscesses on the basis of chronic lesions. The rupture of terminal abscesses can form breast fistulas, sinuses, or ulcers, which are difficult to heal for a long time.

[0003] At present, the mainstream treatment method in my country is still surgical treatment, but it is expensive and causes breast damage, which leads to a decline in the quality of life of young women. The existing operation mainly uses local treatment, and the prognosis is good through treatment methods such as irrigation, suction, and injection of drugs. However, the traditional operation method has the following disadvantages: (1) It requires repeated needle insertion, which seriously damages the breast skin, and because it is in the inflamed area, the needle hole is not easy to heal; (2) When suctioning, it relies on the syringe to withdraw, which can easily lead to excessive or insufficient suction. The former will directly cause necrotic material to block the needle hole, and the latter will cause the irrigation fluid to be unable to be smoothly drawn out; (3) The whole process is time-consuming, the operation is cumbersome, the patient's pain lasts for a long time, and the operator's work efficiency is low.

[0004] The Chinese patent application with application number CN202210361396.7 discloses a mammary duct positioning device, wherein an inner core is coaxially nested in an outer sleeve, and the inner core is hollow, dividing the interior of the outer sleeve into an outer cavity and an inner cavity, the upper end of the inner core is sealed and connected to the outer sleeve, and a plurality of square grooves evenly distributed along its circumference are provided on the outer wall of the outer sleeve, the lower end of the inner core is connected to a piston via an elastic membrane sleeve, the piston is slidably connected in the outer sleeve, and a through hole is coaxially provided on the piston; a plurality of long elastic sheets corresponding to the square grooves are provided at the upper end of the piston, and a conical spring is provided between the lower end of the piston and the bottom of the outer sleeve, and the two ends of the elastic sheet can be squeezed to make the middle part squeezed and bulge through the square groove and protrude from the outside of the outer sleeve; the upper end of the guide wire can be threadedly connected to the inner core, and the lower end of the guide wire is provided with a ball head, and an inclined hole is provided on the ball head, and the two outlets of the inclined hole are respectively facing the lower end and the side of the guide wire. Although this prior art can solve the problem that the prior art devices are not convenient for accurately locating the diseased milk ducts during biopsy or surgery, and cannot cooperate with a ductoscope for flushing and dredging, this prior art has a complex structure and cumbersome operation, and can only flush and aspirate the lesion site, but cannot remove the lesion site.

By controlling the outer sheath to slide along the axial direction of the inner sheath, the cutting structure is covered and exposed, and damage to the patient's normal tissue is avoided when the device is inserted or removed, and the pain of the patient during treatment is reduced. When the lesion site needs to be cut after reaching the lesion site, the outer sheath is controlled to slide to expose the cutting structure, so that the lesion can be cut, and the limiting member is used to prevent the outer sheath from sliding excessively from the inner sheath and falling off.

[0010] Furthermore, the stopper is two nipples arranged at intervals along the axial direction on the outer surface of the inner sheath, and the inner surface of the outer sheath is provided with a notch engaged with the nipple. One of the two nipples is close to the first interface and the second interface, and the other is located near the closed end. The sliding range of the outer sheath is limited by the cooperation of the two nipples and the notch to prevent it from falling off the inner sheath, thereby ensuring safety and convenience in use.

[0011] Furthermore, a handle is provided on the outer surface of the outer sheath, which facilitates the control of the sliding of the outer sheath along the inner sheath, has a simple structure, and is convenient and practical.

[0012] Furthermore, the first interface and the second interface port are both provided with threads, and the first interface and the second interface are provided along the same diameter. The first interface and the second interface are both preferably threaded interfaces, wherein the first interface can be used to connect a syringe or an infusion device screw buckle, so as to facilitate the operation of irrigating the lesion with saline or injecting medicine through the flushing tube during treatment, avoiding repeated injections to cause multiple injuries to the patient's skin, simplifying the operation procedure, reducing the duration of the patient's pain, and improving the operator's work efficiency.

[0013] Furthermore, the port of the second interface is provided with an openable end cap. The second interface is used to control the suction force on the necrotic tissue, and can form a negative pressure environment in the inner sheath by manually blocking it, or can play a negative pressure role by setting the end cap, so as to conveniently control the suction force to smoothly suck the excised necrotic tissue and lavage fluid into the inner sheath through the cutting structure and then suck it out, avoiding the necrotic material blocking the needle port due to excessive suction or the lavage fluid cannot be smoothly drawn out due to insufficient suction, with a simple structure and convenient operation.

[0014] Furthermore, the closed end of the inner sheath is a smooth spherical head, which is easier to enter into the patient's tissue, reduces the pain caused to the patient's tissue when the device enters, and is simple and practical.

[0015] Furthermore, the inner sheath is made of steel material. The inner sheath and the outer sheath are preferably made of steel material, which can be repeatedly used after high temperature sterilization, and is economical and practical.

[0016] Furthermore, the retraction mechanism is an electric suction device, which can control the suction force, is simple to operate, and is convenient to use.
