At least one conductor operatively and separately connect each of the recording or stimulating contact surfaces in communication with external apparatus. The disk portion and shaft portion are structured relative to each other to operatively provide support and anchoring for each other while providing three-dimensional capabilities for detection and control of brain state changes of a subject. Modified embodiments include insertible / retractable electrode wires, both contained in channels and sheathed in axially displaceable cannulae; activating mechanisms for inserting / retracting the electrode wires and / or cannulae; and multiple shaft portions.

The invention discloses a preparation method of personalized 3D printing high tibial osteotomy guide plate, which is used for 3D printing high tibial osteotomy guide plate. Before operation, according to the CT data of patient's knee joint, computer simulation modeling and three-dimensional In the reconstruction program, the deformity of the patient's tibia is printed out at a ratio of 1:1, and the osteotomy position is designed preoperatively through 3D printing technology. Finally, an osteotomy guide that is completely attached to the proximal end of the patient's tibia is designed through the model material. During the process, the proximal end of the tibia is directly attached and the osteotomy operation is started immediately according to the preoperative osteotomy plan. Under the adjustment of ensuring accuracy, the surgical operation steps are simplified, the anesthesia time is shortened, and the safety of the patient is ensured. Extensive clinical promotion effect. According to the proximal tibial fixation plates provided by different manufacturers, the position and direction of the tibial osteotomy can be individually designed, with a certain degree of flexibility.

The invention discloses a universal posterior locking anatomic bone fracture plate for acetabulum. The universal posterior locking anatomic bone fracture plate comprises a right bone fracture plate, bolts and a guide sleeve, wherein the mirror structure of the right bone fracture plate is a left bone fracture plate. The right bone fracture plate is reversed at 0-9 degrees clockwise along the medial axis. The medial axis profile of the right bone fracture plate is an arc-shaped plane in smooth transition. The right bone fracture plate is sequentially divided into a first locking block, a first positioning block, a second locking block, a second positioning block and a third locking block from top to bottom and is provided with a first locking unit hole, a second locking unit hole and a third locking unit hole which form included angles with the surface of the right bone fracture plate at 0-25 degrees. The locking holes are provided with internal threads of the locking holes. The bolts and the guide sleeve are provided with adaptive internal threads. The universal posterior locking anatomic bone fracture plate disclosed by the invention has the advantages that the universal posterior locking anatomic bone fracture plate is optimal in structure, good in universality, good in structural stability, accordant with biomechanical characteristics, good in adhesion on the surface of acetabulum, efficient to use and low in surgical risk.

The present invention provides a drainage tube introducer wherein while a drainage tube is fitted over an introducing end portion (42) protruding through a pin hole (32) and is introduced through an incision portion (4) into an infected portion (2) in cooperation with the introducing end portion (42), a stop block (52) is pressed by pushing a sleeve (70) frontward, which bends an operating lever (50) made of an elastic material to release the stop block (52) from a stop hole (38). Accordingly, a pin (40) is moved rearward by an elastic member (60) to withdraw the introducing end portion (42) protruding through the pin hole and to separate the drainage tube introduced into the infected portion (2) from the introducing end portion (42).

The invention provides a water-soluble preparation of anesthetic eugenol serving as an effective ingredient for fish. The preparation is prepared from the following raw materials in part by weight: 10 to 30 parts of eugenol, 10 to 30 parts of solvent, 1 to 10 parts of thickening agent and 100 parts of deionized distilled water.

The preparation method is simple.

In ultrasonic therapy, the change of the grey scale of a B-mode ultrasound image of a treated point and the change of tissue temperature have a known relationship, so temperature change conditions corresponding to the treated point can be obtained by observing the change of the grey scale of the B-mode ultrasound image of the treated point so as to get an idea of treatment effect. The ultrasonic therapy tissue temperature change display equipment using digital grey scale processing of the invention comprises a B-mode ultrasound image acquisition module, a treated point grey scale determination module and a grey scale curvilinear graph display module which are sequentially connected. In the ultrasonic therapy, the digital grey scale processing of the B-mode image of the treated point is performed, the tissue temperature change conditions are monitored accurately in real time and a curve of the change in tissue temperature of the same treated point before and after treatment is directlydisplayed in a graphical mode, the anesthesia time of a patient in a treatment process is reduced, and the treatment efficiency is improved and the treatment is finished more safely and effectively.

The invention discloses a pressure-limiting injector having a pressure regulating function and a using method thereof. The pressure-limiting injector comprises an injection barrel, an injection piston and a nipple located at the front end of the injection barrel, wherein the injection barrel and an injection piston are matched mutually, and a pressure regulator identical to the injection barrel in arrangement direction is arranged on the side wall of the injection barrel. The using method of the pressure-limiting injector comprises the steps of 1 pulling the injection piston from the 1 / 2 position of the length of the injection barrel to the tail portion of the injection barrel; 2 debugging the pressure regulator to be a set value; 3 connecting the nipple with a pressure sleeve bag air inflation head of a tracheal catheter; 4 propelling the injection piston till the injection piston abuts against the front end of the injection barrel. The pressure-limiting injector has the advantages of being convenient and quick to use, avoiding potential safety hazard caused by subjective factors and decreasing the potential safety hazard and can be widely applied to the field of medical treatment.
