The utility model provides a minimally invasive spine retractor, which belongs to the technical field of medical instruments and comprises a retraction mechanism, the retraction mechanism comprises a base, a middle-layer ring body and an upper-layer ring body, the middle-layer ring body is positioned between the base and the upper-layer ring body, and three limiting openings are formed in the middle-layer ring body at equal intervals in a surrounding manner. A plurality of limiting openings are formed in the middle layer ring body, each limiting opening is movably connected with a distraction frame, a notch is formed in the edge of one side of the middle layer ring body, an elastic piece is arranged in the notch, a positioning block is arranged on the elastic piece, positioning holes are connected to the positioning block in a clamped mode, and the positioning holes are formed in the lower side of the upper layer ring body and distributed at equal intervals. The instrument can be introduced into the body, a channel reaching the focus is rapidly established, meanwhile, the degree of tissue opening is automatically positioned, operation can be conducted with one hand, convenience and rapidness are achieved, the safety and reliability of channel establishment are improved, the structure is simple and stable, and certain practical value is achieved.

The invention discloses a minimally invasive surgery treatment system for benign prostatic hyperplasia and a use method of the minimally invasive surgery treatment system. The system comprises an outer cannula used for entering the body of a patient through the urethra, a handle connected to the outer cannula, a cannula installed in the outer cannula, a stretching tube installed in the cannula, a guide wire installed in the stretching tube, a puncture needle head installed at the free end of the guide wire, a rotation driving mechanism used for driving the guide wire to rotate and a telescopic driving mechanism used for driving the cannula to move. A plurality of cutting knives which are uniformly arranged around the stretching tube are arranged between the free end of the stretching tube and the puncture needle head; a magnetic ring which is magnetically attracted with the puncture needle head is arranged at the free end of the sleeve; a guide wire locking mechanism used for locking the guide wire and a stretching pipe adjusting and locking mechanism used for adjusting the position of the stretching pipe and locking the stretching pipe are further arranged in the handle. The system is reasonable in structural design, the telescopic cutting knife is integrated into the puncture assembly, when the system is used for operation, trauma is small, recovery is fast, only local anesthesia is needed, the effect is fast, and the operation effect is good.

At present, the treatment methods for sarcoidosis include operative treatment, radiochemical treatment and drug treatment (including traditional Chinese medicine decoction). Wherein the operative treatment has a good curative effect on early-stage patients, but the treatment cost is high; the treatment effect on advanced patients is poor; traditional Chinese medicine decoction is long in conditioning time and slow in treatment speed. In order to better treat nodule diseases and overcome the defects in the prior art, the invention provides the liqueur for treating nodules, which can effectively treat various nodules, and has the advantages of simultaneous treatment of medicine and food, small side effect, low cost and good curative effect.

A movement restriction composition for use in a method of treatment of reflux disease treatment by surgery, the movement restriction composition comprising 50% - 100% silicone or 50% - 100% polyurethane. A coronal plane of the patient divides the esophagus of the patient in an anterior half and a posterior half. The treatment by surgery comprises dissecting an area of the patient's stomach, affixing the stomach fundus wall to the lower part of the patient's esophagus by providing sutures or staples, creating a pouch in the stomach fundus wall, and placing and in-vaginating the movement restriction composition in the pouch by providing sutures or staples to the stomach fundus wall. The center of gravity of the movement restriction composition can be positioned dorsal to the coronal plane for preventing the cardia from sliding through the patient's diaphragm opening into the patient's thorax.

The utility model provides a needle holding device, and relates to the technical field of medical instruments, and the needle holding device comprises a base which is fixed relative to the skin of a target body and is provided with two arc grooves which are oppositely arranged; the supporting disc is of an arc-shaped structure, the two ends of the supporting disc are provided with sliding blocks in sliding fit with the two oppositely-arranged arc grooves, and the sliding blocks slide in the arc grooves so that the supporting disc can rotate in the arc direction relative to the base; the needle holding clamp is provided with a body, a needle groove formed in the first face of the body and a clamping arm which is arranged on the second face of the body and extends away from the first face, and the clamping arm can be clamped on the supporting disc in a reciprocating sliding mode along the arc-shaped supporting disc; the locking assembly comprises a first locking structure used for locking the supporting disc and the base, a second locking structure used for locking the needle holding clamp and the supporting disc, and a third locking structure used for being matched with the needle groove to lock the medical needle. The stability of the medical needle in the operation process is enhanced, the operation burden of an operator is reduced, and the puncture accuracy and the operation treatment effect are improved.

The invention provides a low-estrogen ovarian cancer co-disease depression animal model and a construction method thereof, and belongs to the technical field of medicine. The method first establishes an abdominal cavity transplantation tumor by injecting an ovarian cancer cell suspension into the abdominal cavity of a female mouse. And then, after the tumor is formed, performing bilateral ovariectomy to simulate the persistent hypoestrogen state of the ovarian cancer patient caused by operative treatment. And finally, inducing the mouse to generate depression-like behavior phenotypes through chronic constraint stress. The model solves the limitation that an existing model cannot accurately simulate a tumor-low estrogen-depression three-in-one pathological mechanism of an ovarian cancer patient. Experiments prove that the model successfully reproduces the coexistence characteristics of tumor progression acceleration, obvious reduction of estrogen level and typical depression-like behaviors, and provides a reliable research platform for deeply researching the pathogenesis of ovarian cancer co-disease depression and developing a new treatment strategy.
