Description

Technical Field

[0001] The utility model relates to medical equipment technology, in particular to a pleural decorticator. Background Art

[0002] Pleural decortication, also known as decortication of the pleural lamina, is a surgical procedure used to treat pleural diseases, particularly those involving chronic empyema, tuberculous empyema, and organizing hemothorax. The primary goal of this procedure is to remove the thickened fibrous layers (lamina) of the parietal and visceral pleura, thereby eliminating the diseased tissue within the pleural cavity and allowing the lung tissue to expand free of the fibrous lamina. This not only helps maximize lung function but also maintains the normal thoracic morphology.

[0003] Due to the unique conical structure of the chest cavity, using conventional pleural decorticators during pleural decortication surgery often significantly increases the difficulty of stripping the thickened fibrous lamina in areas such as the anterior and posterior costophrenic angles, the inner fissures, and the lung base due to angle limitations and the inevitable tissue bleeding during the process. This not only makes the dissection operation extremely difficult, but also often requires frequent use of suction to remove blood from the field of view, which prolongs the operation and increases the complexity and labor intensity of the procedure. Utility Model Content

[0004] The purpose of the utility model is to provide a pleural decorticator to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a pleural decorticator, comprising a decorticator handle, wherein a cavity is provided in the middle of the decorticator handle, and further comprising:

[0006] A stripper-suction connector is mounted on one side of the stripper handle, and a through hole is formed in the middle of the stripper-suction connector, the through hole of the stripper-suction connector being connected to the cavity of the stripper handle;

[0007] The stripper extension rod is fixedly mounted on the other end of the stripper handle, and a cavity is formed through the middle of the stripper extension rod, and the cavity of the stripper extension rod is connected to the cavity of the stripper handle;

[0008] The extension rod has an external thread, which is provided on the outer side of the stripper extension rod away from the stripper handle;

[0009] A stripper connector, which is threadedly connected to the outer side of the extension rod external thread opened at the end of the stripper extension rod;

[0010] a stripper stripping head, which is mounted on the other end of the stripper joint;

[0011] The suction hole is opened through one side of the stripping head of the stripper.

[0012] Furthermore, one end of the stripper-suction device connector is provided with a stripper connector external thread.

[0013] Furthermore, the inner wall of the stripper joint is provided with an internal thread that is adapted to the size of the external thread of the extension rod.

[0014] Furthermore, the stripper stripping head includes a flat head stripping head.

[0015] Furthermore, the stripper stripping head includes a round-head stripping head.

[0016] Furthermore, the stripper stripping head includes a spoon-shaped stripping head.

[0017] Compared with the existing technology, the utility model provides a pleural decorticator, which uses dissector extension rods with different angles. These dissector extension rods can be flexibly connected to dissector heads of different shapes to cope with the anatomical shape characteristics of different areas in the chest cavity. Each dissector head is provided with a circular hole to which an aspirator can be connected. This design integrates the suction function, so that when dissecting complex areas such as the anterior and posterior costophrenic angles, the lung fissures, and the lung base, there is no need to use a separate aspirator for assistance. This integrated design not only simplifies the surgical process, but also significantly improves the flexibility and freedom of operation, allowing surgeons to complete the dissection of thickened fiber plates more smoothly and efficiently.
