This utility model discloses a lumbar puncture needle with monitoring function, comprising: a needle body, with a puncture needle main body internally connected to the needle body. The puncture needle main body is used to detect puncture depth and monitor cerebrospinal fluid pressure. The puncture needle main body includes an outer needle and an inner needle, with the inner needle located inside the outer needle. A gap is reserved between the outer and inner needles. A signal receiving mechanism is provided at the top of the outer needle. Both the outer and inner needles are electrically connected to the signal receiving mechanism via a point-to-line connection. This utility model provides a lumbar puncture needle with monitoring function, consisting of a system and a puncture needle main body. It can issue an alarm when the puncture needle tip contacts the cerebrospinal fluid in the subarachnoid space of the lumbar spine, and can monitor the cerebrospinal fluid pressure in real time during cerebrospinal fluid collection. Through precise puncture depth feedback and real-time cerebrospinal fluid pressure monitoring, doctors can more accurately locate the puncture point, reduce surgical errors, and improve the success rate of surgery. Real-time monitoring of cerebrospinal fluid pressure helps to detect abnormal intracranial pressure in a timely manner, prevent serious complications such as brain herniation, and ensure patient safety.

The invention discloses a delirium patient self-adaptive pressure adjusting and restraining glove and a using method thereof, and belongs to the technical field of medical auxiliary instruments, the delirium patient self-adaptive pressure adjusting and restraining glove comprises a glove body, the glove body is composed of a wrist part, a palm part and a finger part, the glove body is divided into an outer protective shell, a middle pressure sensing adjusting layer and an inner skin-friendly contact layer, the wrist part is provided with a detachable wrist self-locking fastening mechanism, and the wrist self-locking fastening mechanism restrains the glove body on the wrist of the patient. Aiming at the core problem that the delirium patient moves restlessly and is easy to pull out the catheter, through the design of a finger constraint structure, self-adaptive pressure adjustment and the like, the finger grasping action is accurately blocked, accidental pull-out of the diagnosis and treatment catheter is avoided, serious complications such as airway obstruction, bleeding and infection are reduced, the life risk of the patient is reduced, and the hospitalization time is shortened.

The application discloses a hemorrhoid operation system, which comprises a safe blocking component, an intracavitary radial feed drainage knife group, and an intracavitary negative pressure forced stasis discharge component. The safe blocking component is used for sealing with the intestinal wall to block the downward flow of intestinal excrement. The intracavitary radial feed drainage knife group is used for puncturing a lesion. The intracavitary negative pressure forced stasis discharge component is used for negative pressure action on the punctured lesion to discharge stasis. Thus, the downward flow of intestinal excrement can be blocked to avoid infection of a surgical wound. The cyst at the hemorrhoid lesion is punctured to dredge the stasis discharge channel, and the intracavitary negative pressure forced stasis discharge component is used to forcibly discharge the stasis in the cyst. Compared with traditional hemorrhoid medical instrument operation, the hemorrhoid operation system does not need to cut off the epidermis of the internal hemorrhoid lesion and the large intestinal muscle, has no contraindicated population, and will not cause serious complications such as rectal stenosis and death, and has strong safety and significant clinical application value.

The utility model discloses a channel wire pusher, which comprises a rod part welded at one end of a handle part, claw-shaped pushing hand parts used for pushing wires are distributed at the top end of the rod part, an obtuse angle is formed between the rod part and the handle part, the included angle between every two claw-shaped pushing hand parts is 30 degrees, the included angle between the handle part and the rod part is 160 degrees, and the rod part is connected with the handle part. The number of the claw-shaped pushing hand parts is three, the length of each claw-shaped pushing hand part is 0.4 cm, the diameter of each claw-shaped pushing hand part is 0.2 cm, the length of each handle part is 4 cm, the diameter of each handle part is 1 cm, and the length of each rod part is 15 cm, and the diameter of each rod part is 0.3 cm. The device has the advantages of being small and exquisite, free of surgical view shielding, wide in application range, firm in knotting and the like, assists in dura mater suturing in the spinal microchannel surgery, reduces cerebrospinal fluid leakage after the surgery, and improves the working efficiency. And therefore, the novel medical infusion support disclosed by the utility model has a good use effect.

The invention discloses an ultrasonic probe fixing frame for nerve block, and relates to the technical field of medical instruments. The moving rod is mounted in the bottom frame in a sliding manner; the adjusting mechanism is mounted between the two sides of the top end of the moving rod; a probing mechanism; through cooperative work of the telescopic frame, the telescopic driving assembly, the adjusting frame, the first ultrasonic probe, the second ultrasonic probe and the guide block, the ultrasonic probes are stably fixed with the adjusting frame as the core, the telescopic driving assembly drives the telescopic frame to flexibly move, the adjusting frame accurately adjusts the angle and the distance between the two ultrasonic probes, and the ultrasonic probes can be stably fixed. And the low-frequency curved-surface probe and the high-frequency linear probe are combined, so that accurate three-dimensional space positioning is realized, the complex spatial relationship between cranial nerves and surrounding blood vessels and bones can be comprehensively displayed, synchronous scanning in different directions can be realized, a puncture path can be monitored in real time, accidental injury to the blood vessels or nerves is avoided, and serious complications such as bleeding and infection are prevented.

The application discloses a kind of for thoracolumbar fracture front and rear road's minimally invasive bone cement device and use method, and the application belongs to medical equipment technical field, comprising: puncture guiding mechanism, bone cement mechanism, including passage dilator, the passage dilator is detachably installed with the sheet mechanism in, the bottom of sheet body is arc structure;Bone cement injection mechanism.The application solves the risk of bone cement leakage by setting bone cement bag, and then reduces the risk of bone cement leakage to the spinal canal or paravertebral tissue, so as to avoid nerve damage, pulmonary embolism and other serious complications.The specific shape can be formed in the fractured vertebral body by the setting of the sheet mechanism, the uniform distribution of bone cement in the vertebral body is ensured by introducing bone cement distribution control mechanism, the stability of fractured vertebral body is enhanced, and the treatment effect is improved.Meanwhile, the effective recovery of the height of severely compressed fractured vertebral body is realized, and the postoperative physiological curvature and function of the patient's spine are improved.
