The application relates to the technical field of medical devices, and discloses a positioning and tracking device, an optical positioning system and a surgical mechanical arm. The positioning and tracking device comprises a base and multiple groups of tracking arrays, the multiple groups of tracking arrays are arranged around the inside of the base, each group of tracking arrays comprises at least three tracking elements, and all the tracking elements in the same group of tracking arrays define a plane corresponding to a current tracking array. Alternatively, all the tracking elements in the same group of tracking arrays define a curved surface corresponding to the current tracking array. The positioning and tracking device, the optical positioning system and the surgical mechanical arm provided by the application can improve the problem in the related art that when the included angle between a tracking element and an optical tracking sensor changes greatly in the process of movement of an end instrument, the optical tracking sensor cannot acquire the position of the tracking element, so that the pose of the end instrument cannot be recognized.

The present application relates to the technical field of medical apparatus, and discloses a laparoscopic surgical instrument, which comprises an instrument main body and a front-end instrument, the instrument main body comprises a terminal closed transmission assembly, and the front-end instrument comprises an instrument outer rod and an instrument inner rod; the terminal closed transmission assembly comprises a terminal gear and a reset assembly, the terminal gear is provided with a sliding groove, the instrument inner rod is provided with a limiting part, the limiting part can be inserted into or withdrawn from the sliding groove and drive the terminal gear to rotate; when the front-end instrument is not inserted into the instrument main body, the terminal gear moves to a first limit position under the action of the reset assembly, at this time, the limiting part can be inserted into the sliding groove along with the instrument inner rod; when the front-end instrument is inserted in place, the terminal gear moves to a second limit position under the action of the reset assembly, the sliding groove pulls the instrument inner rod inward, and the jaw of the front-end instrument is closed. The present application also discloses a surgical robot. When the front-end instrument is replaced, the present application facilitates the insertion of the instrument inner rod, and after the front-end instrument is replaced, the jaw of the front-end instrument can be automatically closed.

The invention relates to an interface interaction method and device and computer equipment. The method comprises the steps that under the condition that a display associated with a main operation device displays a first interface, a first mode switching request is received, the first interface displays a three-dimensional image collected by an end instrument associated with the main operation device, and the display is controlled to display the first interface and a configuration interface in response to the first mode switching request, the configuration interface displays configuration parameters of at least one of the main operation device, the tail end instrument and the auxiliary device associated with the main operation device, and the configuration parameters in the configuration interface are adjusted according to operation data collected by the main operation device. By adopting the method, the control flexibility and reliability of the surgical robot can be effectively ensured.

The invention relates to the field of small switch cabinets, in particular to a portable electric power switch cabinet discharge detection terminal, which comprises a switch cabinet shell, a contact detection assembly and a limiting buckling assembly, and is characterized in that one side of the switch cabinet shell is provided with a power connection control backboard, and the power connection control backboard is movably provided with a movable switching assembly capable of moving up and down; when discharge detection is carried out on the switch cabinet shell, the detection terminal instrument is movably connected by overturning the mounting plate, and then the contact detection assembly of the detection terminal instrument is in contact with the switch cabinet shell, so that real-time detection numerical value reading is realized during normal operation and use, and more stable wireless transmission is carried out through the transceiving placement groove; during non-detection operation, through cooperation of the movable switching assembly and the limiting buckling assembly, the moving wheels can stably extend out of the storage groove to be used for portable movement of the switch cabinet shell, meanwhile, a detection terminal instrument installed on the overturning installation plate can be shielded and protected, and operation is free of worry and convenient.

The invention relates to the technical field of surgical robots, and discloses a surgical robot horizontal telescopic structure and a redundancy safety control method, power is provided through meshing transmission of a driving unit and a rack, and full-stroke redundancy position feedback and verification are achieved through a first position detection unit and a second position detection unit. On the basis, the first braking unit and the second braking unit are combined to form a dual-braking guarantee, so that the system can be in a braking release state, the mobile end can be directly pushed from the outside, and smooth and visual manual positioning is realized; in the brake locking state, the movable end is in rigid connection with the fixed base, at the moment, the driving unit can conduct fine force control or position control on the movable end, and the tail end instrument is driven to achieve submillimeter-level precise micro motion. According to the design, the movement of the mobile terminal can be reliably switched between high-flexibility manual adjustment and high-stability precise operation, so that the comprehensive requirements of the surgical operation on positioning convenience, operation accuracy and system safety are met.

The embodiment of the invention provides an instrument, an auxiliary device, an operation part and an operation method. The instrument comprises a sheathing canal and an end instrument located at the far end of the sheathing canal, the sheathing canal comprises a sheathing canal body part and a deflection part, and the deflection part is located in the far end area of the sheathing canal.

The invention relates to a method for a device of a subnetwork, in particular a terminal device, of a wireless communication system, comprising: sending a request for transmitting first information, in particular to a device, in particular for a control device of the subnetwork, the first information enabling a check for the authenticity of at least one device associated with the subnetwork; receiving a response having at least the first information.

The invention discloses a test system, a test method and a storage medium. The test system comprises a calibration device used for calibrating radio frequency transmit-receive parameters of a to-be-tested communication module; the final testing device is used for testing the radio frequency transceiving function of the communication module to be tested; the pin testing device is used for testing an interface function of the communication module to be tested; wherein the calibration device, the final test device and the pin test device sequentially execute corresponding functions according to a preset sequence. The communication module to be tested is correspondingly tested in sequence through the modularized calibration device, the final test device and the pin test device, so that the integrity of the function test is ensured, the mass production test of the communication module is realized, the throughput of a production line is improved, and the test efficiency is further improved; and meanwhile, the test of the communication module can be completed without a specific high-end instrument, so that the test cost is reduced.
