When placing medical tray 405, at first place medical tray 405 at the top of carriage, then push down medical tray 405, make medical tray 405 downstream, at this in-process, the bottom extrusion briquetting of medical tray 405, the briquetting drives the locating piece motion, make the locating piece rotate around the round pin axle, and the locating piece can drive the locating plate motion, make the top joint of locating plate and medical tray 405, can realize the installation of medical tray 405 this moment, when demolising medical tray 405, pull the locating plate, make the locating plate take place to deform, can relieve the spacing of medical tray 405.
In actual use, firstly, the surgical instrument in the corresponding medical tray 405 needs to be taken out, the weight value detected by the weight sensor is reduced, the type of the surgical instrument is obtained correspondingly according to the reduction amount of the weight value, and the position and the angle of the clamping assembly 3 are adjusted in advance according to the type of the surgical instrument.
Then, the medical staff is required to clamp and fix the nerve tissue by means of the surgical instrument, the direction and the angle of the surgical instrument are adjusted according to the subsequent operation, and the clamping force of the surgical instrument on the nerve tissue is met, namely, the surgical instrument cannot cause obstruction to the subsequent operation, and the like, the angle of the clamping component 3 is adjusted to continuously move towards the end of the surgical instrument, and the two opposite elastic clamping mouths 313 are opened towards two sides, at the moment, the clamping arm 311 drives the electromagnetic block 309 to move towards the end far away from the surgical instrument through the connecting arm 310, the gap between the two elastic clamping mouths 313 is increased, then the clamping component 3 is moved to move the two elastic clamping mouths 313 to two sides of the surgical instrument, the position of the elastic clamping mouth 313 is adjusted according to the type of the surgical instrument, the elastic clamping mouths 313 and two sides of the surgical instrument are mutually clamped, the clamping mouths 313 and two sides of the surgical instrument cannot influence the clamping work of the nerve tissue by the surgical instrument, the surgical instrument is still held by the medical staff, the surgical instrument, the position of the clamping component 3 is continuously adjusted, when pressure values detected by the multiple sets of the pressure sensors of the elastic clamping mouths 313 have pressure differences, when the pressure differences detected by the multiple sets of the pressure sensors, the pressure values of the multiple sets of the pressure sensors are continuously adjusted, the clamping components 313, the angle and the angle of the elastic clamping component 313 is further parallel to the surgical instrument.
Specifically, when the pressure value detected by the pressure sensor at the end of the elastic clip nozzle 313 located at the bottom of the surgical instrument, which is far away from the electromagnetic block 309, is greater than the pressure value detected by the pressure sensor at the other positions, it is indicated that an included angle exists between the elastic clip nozzle 313 and the surgical instrument, and the included angle between the elastic clip nozzle 313 and the horizontal plane is smaller than the included angle between the surgical instrument and the horizontal plane, at this time, the included angle between the elastic clip nozzle 313 and the horizontal plane needs to be continuously increased by adjusting the elastic clip nozzle 313, so that the state that the elastic clip nozzle 313 is parallel to the surgical instrument is realized, the stability and the angle of the surgical instrument cannot be affected by the elastic clip nozzle 313, the clamping stability and the clamping durability of the clamping assembly 3 on the surgical instrument are further improved, and the accuracy of the surgical instrument on clamping and fixing the nerve assembly is ensured.
After the angle of the elastic clamping mouth 313 is adjusted, the elastic clamping mouth 313 and two side ends of the surgical instrument are clamped, the surgical instrument is effectively and elastically clamped by means of the elastic force of the elastic clamping mouth 313 in the clamping process, so that the protection and the support of the device to the surgical instrument are improved, in the conventional device, the electromagnetic block 309 is elastically limited and supported only by a spring, the electromagnetic block 309 clamps the elastic clamping mouth 313 through the connecting arms 310 and the clamping arms 311 on the two sides, the clamping force of the elastic clamping mouth 313 to the surgical instrument is constant, the clamping force of the surgical instrument on the nerve tissue is different due to different types of the surgical instrument, the opening angle of the surgical instrument after clamping the nerve tissue is different, the clamping force applied by the surgical instrument on the nerve component is different, when the clamping force is too large, the damage of the nerve tissue is caused, when the clamping force is too small, the falling of the nerve tissue is caused, the effect on the neurosurgery is caused, therefore, after the elastic clamping mouth 313 and the surgical instrument are clamped, the pressure values detected by multiple groups of the pressure sensors are continuously increased, and when the pressure values detected by the pressure sensors are greater than the preset pressure value detected by the magnetic clamping arm 309, the magnetic clamping block 309, the magnetic clamping arm is further reduced by means of the magnetic clamping arm, and the magnetic clamping arm 311 of the magnetic clamping block 309, and the magnetic clamping arm is further reduced.
In particular, the weight difference values detected by the weight sensors are different corresponding to different surgical instruments, when the pressure sensors on the surface of the elastic clamping nozzle 313 detect pressure values, the elastic clamping nozzle 313 is in contact with the surgical instrument, and when the pressure sensors do not detect the pressure values, the elastic clamping nozzle 313 is not in contact with the surgical instrument at the part, the opening angle of the surgical instrument is correspondingly obtained, the clamping force required by the surgical instrument under the condition is correspondingly obtained according to the type of the surgical instrument, and further the pressure preset value of the pressure sensor is obtained, so that the pressure preset value of the pressure sensor is related to the weight difference value detected by the weight sensor and the pressure values detected by the pressure sensors.
After clamping the surgical instrument, medical personnel can loosen the surgical instrument and start follow-up surgery, the surgical instrument is clamped and fixed by the aid of the elastic clamp mouth 313, further, the surgery strength of the medical personnel is reduced, the accuracy and the stability of the surgery are improved, after the surgery is finished, the medical personnel are required to hold the surgical instrument, the controller controls the electromagnetic block 309 to be powered off, the clamping arm 311 is opened reversely, the elastic clamp mouth 313 and the surgical instrument are separated, the supporting tube 207 is pushed to enable the device to be far away from the surgery position, and then the surgical instrument is taken down to complete the surgery.
The device reduces the labor intensity of medical personnel, has high operation precision and simple operation, simultaneously has good clamping fixation of the elastic clamping mouth 313 to the operation instrument, self-adaptively adjusts the clamping force, makes the clamping component 3 parallel to the operation instrument, has strong clamping stability and is durable and stable in clamping.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
