Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a pleural adhesion separator. Background Technology

[0002] Pleural adhesions refer to abnormal adhesions between the visceral and parietal pleura caused by the proliferation of fibrous tissue. They can occur locally or over a wide area and are commonly seen in pulmonary tuberculosis, pleurisy, chest trauma, or during postoperative recovery. After pleural adhesions occur, the pleural effusion cannot be drained, and medication or a separator is usually needed to separate the adhered pleura.

[0003] The pleural adhesion separator disclosed in utility model patent CN2862992Y comprises a cannula, a needle, two guidewires, a horizontal axis, and a needle core. One end of the needle and one end of the two guidewires are fixed to a horizontal axis. A cannula with side holes is fitted over the needle. The other ends of the two guidewires are fixed to the side holes of the cannula. A solid needle core is inside the needle, which has a fixing hole. The cannula is connected to the needle through the fixing hole. This design facilitates the cutting of adhesions, eliminates septa, and promotes the aspiration and absorption of pleural effusion.

[0004] However, the above-mentioned technical solutions cannot guide and lock the puncture depth of the cannula during the insertion process, which affects the puncture accuracy of the cannula. At the same time, they cannot adjust the guidewire separation range according to the pleural adhesion range, which is not convenient for rapid separation of the pleura. Therefore, we propose a pleural adhesion separator. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a pleural adhesion separator, including an outer sleeve 2, and an inlet structure 3 movably disposed inside the outer sleeve 2 for precise positioning of the puncture site;

[0029] The inlet structure 3 includes an inner sleeve 32, which is detachably installed inside the outer sleeve 2. An inlet head 31 is also provided at one end of the inner sleeve 32. Positioning knobs 36 for locking the inlet position of the inner sleeve 32 are also provided on both sides of the outer sleeve 2. Positioning sliders 34 are provided on both sides of the outer surface of the inner sleeve 32. One end of the positioning slider 34 is slidably installed in the positioning groove 33, which is located on both sides of the inner wall of the outer sleeve 2. When the inner sleeve 32 moves inside the outer sleeve 2, it can guide the movement of the inner sleeve 32. The positioning knobs 36 are rotatably installed on both sides of the outer sleeve 2 and extend into the positioning groove 33. By abutting against the positioning sliders 34, the positioning sliders 34 can be locked and fixed. Specifically, scale marks are also provided on the outer surface of the inner sleeve 32, which can accurately indicate the insertion depth.

[0030] During the insertion process, the outer sleeve 2 is placed in the patient's chest cavity insertion position, and then the inner sleeve 32 is inserted into the outer sleeve 2, and the positioning slider 34 is engaged in the positioning groove 33. The inner sleeve 32 is pushed, and the inner sleeve 32 drives the positioning slider 34 to move in the positioning groove 33. The inner sleeve also drives the inlet head 31 to move in the outer sleeve 2, and the inlet head 31 is inserted into the patient's chest cavity. The insertion position can be accurately known according to the scale markings on the inner sleeve 32. When it is inserted into the patient's chest cavity, the positioning knob 36 is tightened. The positioning knob 36 engages with the positioning slider 34 and fixes the positioning slider 34 in the positioning groove 33, thereby accurately positioning the inner sleeve 32.

[0031] Furthermore, a first handle 35 is provided at the end of the inner sleeve 32, which facilitates the insertion of the inner sleeve 32.

[0032] The inlet head 31 in this application has a hollow structure, which facilitates the movement of the pleural septum structure 4.

[0033] Please see Figure 5 as well as Figure 6 The inner sleeve 32 is also provided with a pleural septum structure 4, which includes an inner core rod 41. The inner core rod 41 is movably disposed within the inner sleeve 32. A support sleeve 45 is movably disposed at the bottom of the inner core rod 41. An adjusting sleeve 44 is also provided on the inner core rod 41 to adjust the longitudinal position of the support sleeve 45. During the insertion of the inner core rod 41, the longitudinal position of the support sleeve 45 can be adjusted. The adjusting sleeve 44 is connected to a threaded section 43, which is disposed on the outer surface of the inner core rod 41 and can position the longitudinal adjustment position of the support sleeve 45. Guide wires 46 are also provided on both sides of the support sleeve 45. One end of the guide wire 46 is connected to the inner core rod 41 and the deformation range of the guide wire 46 can be adjusted.

[0034] After the inner sleeve 32 is positioned, the inner core rod 41 is inserted into the inner sleeve 32. The inner core rod 41 is pushed and passes through the guide head 31, moving the guide wire 46 to the location of the pleural adhesion. Based on the extent of the pleural adhesion, the elastic deformation range of the guide wire 46 is adjusted. The adjusting sleeve 44 rotates along the threaded section 43 and moves downwards. The downward movement of the adjusting sleeve 44 causes the support sleeve 45 to move downwards, which in turn compresses the guide wire 46, causing the guide wire 46 to... 6. Elastic deformation occurs, and the range of elastic deformation of guidewire 46 is controlled. Then, the inner core rod 41 is rotated, which drives the guidewire 46 to rotate. The rotation of guidewire 46 breaks the fibers adhering to the pleura. After the pleura is separated, the adjusting sleeve 44 is rotated in the opposite direction. The adjusting sleeve 44 moves upward, and the guidewire 46, under the action of elasticity, drives the supporting sleeve 45 to move upward, thereby resetting the guidewire 46. Then, the inner core rod 41 and guidewire 46 are moved out of the inner sleeve 32, and then the pleural effusion can be drained.

[0035] Furthermore, a second handle 42 is provided at one end of the inner core rod 41, which can control the rotation of the inner core rod 41 through the second worm gear.

[0036] Furthermore, guide sliders 48 are provided on both sides of the inner wall of the support sleeve 45. The guide sliders 48 are slidably disposed in the guide grooves 47. The guide grooves 47 are symmetrically disposed and connected to the inner core rod 41. When the adjusting sleeve 44 drives the support sleeve 45 to move, the support sleeve 45 drives the guide sliders 48 to move in the guide grooves 47 and guides the movement position of the support sleeve 45.

[0037] Furthermore, a support plate 1 is provided at the top of the outer sleeve 2. The diameter of the support plate 1 is larger than that of the outer sleeve 2. Specifically, the bottom of the support plate 1 is made of skin-friendly material, which improves the comfort during use and also improves the support stability of the outer sleeve 2.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
