The invention relates to a head, neck and upper limb joint movement device used after operation for repairing the oral and maxillofacial defect through pectoralis major myocutaneous flaps. The head, neck and upper limb joint movement device mainly comprises a head cover. One side of the head cover is sequentially and fixedly connected with a neck cover, a shoulder cover, an upper arm cover, an elbow cover and a forearm cover. The neck covers, the shoulder covers, the upper arm covers, the elbow covers and the forearm covers act in a synthetic mode to force the head, the shoulders, the upper arms, the elbows and the forearms to rotate in the same direction. By means of the device, the head, the neck, the shoulders and the upper limbs of a patient can be moved synchronously, one certain portion does not move independently, and post-operation healing can be effectively promoted.

The invention discloses a bullet-shaped cerebral porous drainage tube and a cerebral drainage device adopting same, which comprises a bullet-shaped cerebral porous drainage tube, an input catheter, a metering reservoir, an output catheter, a liquid storage drainage bag and the like. The bullet-shaped cerebral porous drainage tube comprises a a tube body, the front end of the tube body is a dead end and the rear end thereof is a tube joint which is opened, the front end of the tube body is opened with at least two side holes, and the dead end is a bullet-shaped dead end. The invention has reasonable structure, the bullet-shaped dead end design of the drainage tube can reduce the damage to the brain tissue during the puncturing process, and has slippage effect, can slip to pass during the puncturing process if touching the blood vessel or nerves, thereby, the damage to the blood vessel and the nerves are prevented and avoided during the puncturing process, and intracranial hemorrhage, hematoma, aphasia, paralysis, neural paralysis and various complications can be reduced during the puncturing process.

The invention discloses an absorbable sac for preventing epidural scar formation, comprising a biodegradable sac body provided thereon with a cavity filled with an absorbable liquid material and provided thereon with fixing members. The sac body filled with the absorbable liquid material is gradually thinned from the middle to the end, and during the process, the spilled absorbable liquid material (sodium hyaluronate) from the sac can keep the action of preventing and reducing epidural scar formation for a while. Finally, all the components in the sac are degraded into water and carbon dioxide. After the absorbable liquid material is absorbed, the vertebral plate deficient region is replaced by loose tissue, so as to prevent tight adhesion between dural sac and musculus sacrospinalis and prevent a large amount of hyperplastic scar tissue pressing dural sac to induce symptom recurrence.

The application of N6022 in the treatment of aortic dissection and aortic aneurysm involves the cardiovascular field. In mouse models of aortic dissection and aortic aneurysm, tail vein injection of N6022 can inhibit the expansion of the aorta, reduce the incidence and mortality of arterial dissection and aortic aneurysm; and N6022 can reduce the rupture of aortic aneurysm, inhibit The occurrence of hematoma in the inner wall of the lumen and the excessive collagen deposition on the vessel wall maintain the integrity of the elastic fibers of the vessel wall and treat aortic dissection and tumor diseases. The invention opens up a new application field of N6022, and provides a meaningful reference for preventing and treating aortic dissection and aortic aneurysm diseases and improving vascular pathological changes.

The invention relates to a magnetic splint for a nasal septum. The magnetic splint comprises two nasal septum pressurizing pieces which are separately arranged on the two sides of the nasal septum, wherein the two nasal septum pressurizing pieces can be mutually attracted through magnetic force so as to press the nasal septum; at least one of the nasal septum pressurizing pieces comprises a plurality of movable splinting pieces which extend along the nasal septum; the plurality of movable splinting pieces are mutually hinged through a rotating shaft; the rotating shaft extends in a way of being perpendicular to the movable splinting pieces; the movable splinting pieces are hinged through the same rotating shaft to ensure that a folding position and an unfolding position are provided; on the folding position, the plurality of movable splinting pieces are overlapped and extend along the nasal septum in a collinear manner; on the unfolding position, the plurality of movable splinting pieces cover the nasal septum in a fanwise form; countersink grooves in which the end part of the rotating shaft is accommodated are formed in the outer surfaces of the movable splinting pieces close to the nasal septum; the thickness of each of the movable splinting pieces is not more than 1mm. According to the magnetic splint disclosed by the invention, the technical problems that a nasal septum mucous membrane splint has a complicated structure and the coverage area is smaller in the prior art are solved.

The invention discloses a medicine for postoperative rehabilitation of cerebral hemorrhage, in order to solve a problem of cerebral hemorrhage postoperative rehabilitation. The medicine is characterized by being processed by a variety of traditional Chinese medicines; and a formula and weight ratio of raw materials are as below: 8-15 parts of Polygonum multiflorum, 8-15 parts of cassia twig, 6-10 parts of radix curcumae, 6-10 parts of trichosanthes kirilowii Maxim, 8-15 parts of root of bidentate achyranthes, 6-10 parts of herb of Rose Glorybind, 6-10 parts of lluffa, 8-15 parts of rhizoma acori graminei and 3-6 parts of leech. Clinical experiments have proves that the medicine for postoperative rehabilitation of cerebral hemorrhage of the invention has the characteristics of good curative effect, and is worthy of clinical application and promotion.

The invention provides an axillary osmidrosis pumping and scraping needle with a round head. The axillary osmidrosis pumping and scraping needle with the round head is composed of a sucking pipe body, a connector and a handle. The sucking pipe body is a cylindrical hollow pipe, the connector is located at the tail end of the sucking pipe body, the sucking pipe body is connected with the handle through the connector, the front end of the sucking pipe body is in the shape of a closed cone, a relatively-pointed head end is arranged at the front end of the sucking pipe body, and three or four side holes are formed in the portion close to the head end. According to the axillary osmidrosis pumping and scraping needle with the round head, the number, size, arrangement and the like of the side holes are reasonable in design, the side holes can pump, scrape and cover the whole holding position at a time, the pumping and scraping holes are reasonable in arrangement, and a small range can also be pumped and scraped. The design of the conical front end enables the needle to be tightly attached to and inserted into the deep face of the corium along the original layer face, the situations that the skin is penetrated, an operator is injured, and muscles in the deep face are damaged are avoided, and the axillary osmidrosis pumping and scraping needle with the round head meets operation requirements, is safe and effective to use, and easy to popularize and use.
