Description

Technical Field

[0001] The invention relates to the technical field of operating room equipment, in particular to a clamping type operating room equipment lifting frame with a tightening function. Background Art

[0002] In modern medical surgery, efficient and safe management and use of surgical instruments are crucial. Traditional equipment support racks usually have open trays, which have many shortcomings in practical applications. With the continuous advancement of medical technology and the increasing complexity of surgery, the sterility requirements for surgical instruments are becoming more stringent. Open trays cannot provide effective sealing protection when the instruments are not in use, and are easily contaminated by the outside world, increasing the risk of surgical infection.

[0003] During surgery, time is life, and doctors need to quickly and accurately obtain the required surgical instruments. However, the existing open tray-type lifting racks cannot automatically store and retrieve instruments, which not only affects the efficiency of the operation, but may also cause operational errors due to the doctor's hasty search for instruments. In addition, since the tray is always open, surgical instruments are exposed to the external environment for a long time and may be contaminated by dust, droplets, etc., and are also susceptible to accidental collisions and displacement or damage. Furthermore, from the perspective of operating room management, open trays are not conducive to accurate management of the number and types of surgical instruments, and instruments may be missed or misplaced.

[0004] In addition, in surgeries with certain special body positions, in order to flexibly adapt to operational requirements, doctors need to adjust the angle of access to instruments according to the specific circumstances of the surgery and personal operating habits. Therefore, the door of the surgical instrument storage device must be opened to different angles and fixed. The existing open tray-type lifting rack is also difficult to meet the above requirements.

[0005] In view of this, we propose a clamping type operating room equipment lifting frame with a tension function to improve the deficiencies in the prior art. Summary of the invention

During the opening and closing process of the hinged door, the positioning assembly can slide on the top of the clamping assembly, and the positioning assembly is used to fix the hinged door at different angles.

[0010] When the clamping assembly is pulled out from the storage bin, several of the elastic assemblies are used to extract air from the top of the clamping assembly. When the clamping assembly is retracted into the storage bin, several of the elastic assemblies can blow air toward the top of the clamping assembly.

[0011] As a further improvement of the present technical solution, the clamping assembly includes a tray, which includes a clamping layer and a movable layer arranged from top to bottom, a plurality of clamping arms are provided on the top of the clamping layer, and a pair of symmetrically arranged clamping arms are provided between two adjacent clamping arms, a plurality of guide rods are fixedly connected to the side of the clamping arm close to the dividing bar, and the ends of the plurality of guide rods away from the clamping arm are slidably connected to the dividing bar, and a first spring is sleeved on the periphery of the plurality of guide rods between the dividing bar and the clamping arm.

[0036] Example

[0037] See also Figure 1-Figure 6 As shown, the purpose of this embodiment is to provide a clamping type operating room equipment lifting rack with a tightening function, including a packaging box 12 fixedly connected to the top of a bracket 11, a storage bin 13 is downwardly opened at the top of the packaging box 12, and a pair of symmetrically arranged hinged doors 14 are hinged at the top of the storage bin 13;

[0038] Among them, a clamping assembly 20 is slidably connected in the storage bin 13, a pair of linkage assemblies 30 are movably connected between the top of the clamping assembly 20 and the two hinged doors 14, and the two pairs of linkage assemblies 30 are respectively located on two sides away from the clamping assembly 20, and a positioning assembly 40 is provided between the bottom of several linkage assemblies 30 and the top of the clamping assembly 20, and several elastic assemblies 50 are provided at the bottom of the clamping assembly 20, and the bottoms of several elastic assemblies 50 are fixedly connected to the inner bottom wall of the storage bin 13;

[0039] The clamping assembly 20 is used to fix surgical instruments, and the hinged door 14 is used to open the storage bin 13 when the surgical instruments need to be used. The hinged door 14 can also store the clamping assembly 20 when the surgical instruments are not in use. When the hinged door 14 is opened from the top of the storage bin 13, the linkage assembly 30 can pull the clamping assembly 20 out from the storage bin 13. When the hinged door 14 is closed, the linkage assembly 30 can also push the pulled-out clamping assembly 20 back into the storage bin 13. In the process of opening and closing the hinged door 14, the positioning assembly 40 can slide on the top of the clamping assembly 20. The positioning assembly 40 is used to fix the hinged door 14 at different angles.

[0040] When the clamping assembly 20 is pulled out from the storage bin 13 , several elastic assemblies 50 are used to extract air from the top of the clamping assembly 20 . When the clamping assembly 20 is retracted into the storage bin 13 , several elastic assemblies 50 can blow air toward the top of the clamping assembly 20 .

[0041] Working principle: First, place the surgical instrument to be used in the clamping assembly 20, then close the two hinged doors 14, and the hinged doors 14 push the clamping assembly 20 back into the storage bin 13 through the linkage assembly 30;

[0042] When it is necessary to access the surgical instruments stored in the storage bin 13, the hinged door 14 is opened, and the hinged door 14 pulls the clamping assembly 20 through the linkage assembly 30, and pulls the clamping assembly 20 originally in the storage bin 13 to the top of the storage bin 13. During this period, the positioning assembly 40 slides along the top edge of the clamping assembly 20. During the sliding process of the positioning assembly 40, the hinged door 14 is rotated to different angles according to the operating habits of the surgeon who accesses the surgical instruments, and then the hinged door 14 is fixed by the positioning assembly 40. When the hinged door 14 is locked by the linkage assembly 30, the hinged door 14 is locked. During the process of pulling the clamping assembly 20 containing the surgical instrument out of the storage bin 13 by the movable assembly 30, the tension assembly 50 draws air from the top of the clamping assembly 20 to the inside of the clamping assembly 20, so that the surgical instrument can be tightly attached to the top of the clamping assembly 20. After the position of the hinged door 14 is fixed, the surgical instrument is taken out of the clamping assembly 20; on the contrary, when the hinged door 14 pushes the clamping assembly 20 back into the storage bin 13, the tension assembly 50 blows air toward the surgical instrument, thereby blowing away dust and other foreign matter on the clamping assembly 20 and the surgical instrument.

[0043] like Figure 4 As shown, first, the specific structure and working state of the linkage assembly 30 are disclosed. The linkage assembly 30 includes a telescopic slot 31 rotatably connected to the hinged door 14 and a slider 32 slidably connected to the top of the tray 21. The top of the slider 32 is rotatably connected to a telescopic rod 33, and the telescopic rod 33 is slidably connected to the telescopic slot 31. The outer periphery of the telescopic rod 33 is sleeved with a second spring 34.

[0044] Furthermore, the stiffness coefficient of the second spring 34 is greater than the stiffness coefficient of the third spring 42; when the hinged door 14 is opened, the hinged door 14 pulls the telescopic slot 31 connected to its own rotation, and the telescopic slot 31 pulls the telescopic rod 33 through the second spring 34, and the telescopic rod 33 pulls the slider 32 connected to its own rotation to slide in the slide slot 35. During this period, the second spring 34 is stretched. Since the stiffness coefficient of the second spring 34 is greater than the stiffness coefficient of the third spring 42, the elastic force difference between the second spring 34 and the third spring 42 pulls the clamping assembly 20 out of the storage bin 13.

[0045] Figure 5 The working state of the positioning assembly 40 when it is pulled by the linkage assembly 30 and slides in the slide groove 35 is shown. The specific structure of the positioning assembly 40 is disclosed below. The positioning assembly 40 includes a slide groove 35 opened on the top of the tray 21 and a mounting groove opened on one side of the slider 32. The positioning assembly 40 also includes a plurality of clamping holes 41 opened on the inner side wall of the slide groove 35. The mounting groove is fixedly connected to a third spring 42 at one end away from the groove, and the third spring 42 is fixedly connected to a clamping block 43 at one end close to the groove of the mounting groove.

[0046] Furthermore, when the slider 32 slides in the slide groove 35, the block 43 is compressed back into the installation groove together with the third spring 42 under the action of the pressure of the inner wall of the slide groove 35, until the hinged door 14 rotates to an angle that conforms to the user's taking habits. At this time, the slider 32 slides to the installation groove facing the clamping hole 41. At this time, the third spring 42 loses the pressure of the inner wall of the slide groove 35, and the block 43 is pushed into the clamping hole 41 under the action of the restoring force of the third spring 42, thereby fixing the hinged door 14 at the current angle.

[0047] Figure 6 The different working states of the tension assembly 50 when the clamping assembly 20 is pulled out and retracted into the storage bin 13 are shown, and then the specific structure of the tension assembly 50 is disclosed. The tension assembly 50 includes a compression bin 51 opened in the clamping layer, a plurality of vent holes 52 are opened on the top of the compression bin 51, a piston 53 is slidably connected in the compression bin 51, a fixed rod 54 is fixedly connected to the bottom of the piston 53, the fixed rod 54 is slidably connected to the tray 21, and the bottom of the fixed rod 54 is fixedly connected to the inner bottom wall of the storage bin 13, a plurality of fourth springs 55 are arranged between the top of the piston 53 and the inner top wall of the compression bin 51, and the two ends of the plurality of fourth springs 55 are respectively fixedly connected to the top of the piston 53 and the inner top wall of the compression bin 51;

[0048] Furthermore, during the process of the clamping assembly 20 being pulled out of the storage bin 13 by the telescopic rod 33 and the telescopic slot 31, the piston 53 slides in the compression bin 51, and air is pumped into the compression bin 51 from the outside through the vent hole 52. Moreover, due to the blocking effect of the fourth spring 55, during the process of the clamping assembly 20 being pulled out, the piston 53 continues to pump air into the compression bin 51, and the air flow continues to enter the compression bin 51, so that the surgical instrument is always close to the top of the clamping assembly 20; on the contrary, when the hinged door 14 is closed, the piston 53 slides in the compression bin 51 to blow air toward the top of the clamping assembly 20, thereby blowing away foreign objects on the surgical instrument.

[0049] Since surgical instruments have different functions and uses, they are prone to confusion when not stored separately. During an emergency operation, doctors may waste precious time because they cannot quickly find the specific instruments they need, which affects the progress and effect of the operation. Secondly, different surgical instruments have different requirements for hygiene and sterility. Furthermore, some surgical instruments have special materials or structures and require a specific storage environment to maintain their performance and accuracy. If they are randomly placed with other instruments, they may be squeezed, collided or affected by improper environment, resulting in damage to the equipment or degradation of its performance.

[0050] like Figure 3As shown, the clamping assembly 20 includes a tray 21, and the tray 21 includes a clamping layer and a movable layer arranged from top to bottom. A plurality of clamping arms 23 are provided on the top of the clamping layer, and a pair of symmetrically arranged clamping arms 23 are provided between two adjacent clamping arms 23. A plurality of guide rods 24 are fixedly connected to one side of the clamping arm 23 close to the dividing bar 22, and one end of the plurality of guide rods 24 away from the clamping arm 23 is slidably connected to the dividing bar 22, and a first spring 25 is sleeved on the periphery of the plurality of guide rods 24 between the dividing bar 22 and the clamping arm 23.

[0051] The improvements are as follows: the height of the tray 21 is less than the depth of the storage bin 13; the depth of the storage bin 13 is greater than the height of the tray 21, so that the surgical instruments can be retracted into the storage bin 13 for storage when not in use, and the tray 21 is pulled out from the storage bin 13 during surgery for the surgeon to use the surgical instruments; when in use, the two arc-shaped clamping arms 23 are moved apart from each other to take out the surgical instruments fixed between the two clamping arms 23 from the inside, during which the first spring 25 is always in a compressed state, and after use, the two clamping arms 23 are reset under the action of the restoring force of the first spring 25.

[0052] Since it is ensured that the vent hole 52 can always draw air into the compression chamber 51 during the opening of the hinged door 14, the stability of the surgical instrument in the vertical direction is ensured during the process of the tray 21 being pulled out of the storage chamber 13;

[0053] like Figure 6 As shown, the radius of the plurality of vent holes 52 is smaller than the radius of the compression chamber 51 .

[0054] The improvement lies in that the radius of each compression chamber 51 is set to be much larger than the radius of each vent hole 52 on its own top, so that the separation of the piston 53 pumping and blowing air into the compression chamber 51 through the vent hole 52 is increased, and under the action of the hysteresis response of the fourth spring 55 on the top of the piston 53, the time for the piston 53 to pump and blow air into the compression chamber 51 through the vent hole 52 is extended.

[0055] In summary, the working principle of this solution is as follows: first, the surgical instrument to be used is placed between two adjacent clamp arms 23, and then the two hinged doors 14 are closed, and the hinged doors 14 push the tray 21 back into the storage bin 13 through the telescopic slot 31 and the telescopic rod 33;

[0056] When it is necessary to access the surgical instruments stored in the storage bin 13, the hinged door 14 is opened, and the hinged door 14 pulls the telescopic slot 31 connected to its own rotation, and the telescopic slot 31 pulls the telescopic rod 33 through the second spring 34, and the telescopic rod 33 pulls the slider 32 connected to its own rotation to slide in the slide slot 35. During this period, the second spring 34 is stretched. Since the stiffness coefficient of the second spring 34 is greater than the stiffness coefficient of the third spring 42, the elastic force difference between the second spring 34 and the third spring 42 pulls the tray 21 out of the storage bin 13.

[0057] While the tray 21 is being pulled out of the storage bin 13, the slider 32 slides along the slide groove 35. During the sliding process of the slider 32, the hinged door 14 is rotated to different angles according to the operating habits of the doctor who uses the surgical instruments. Under the pressure of the inner wall of the slide groove 35, the block 43 is compressed back into the mounting groove together with the third spring 42 until the hinged door 14 is rotated to an angle that conforms to the user's habits. At this time, the slider 32 slides to the mounting groove facing the hole 41. At this time, the third spring 42 loses the pressure of the inner wall of the slide groove 35, and the block 43 is pushed into the hole 41 under the action of the restoring force of the third spring 42, thereby fixing the hinged door 14 at the current angle.

[0058] When the hinged door 14 slides relative to each other between the telescopic slot 31 and the telescopic rod 33 to pull the tray 21 with the surgical instruments out of the storage bin 13, the piston 53 slides in the compression bin 51 to draw air from the outside into the compression bin 51 through the vent hole 52. Due to the blocking effect of the fourth spring 55, the piston 53 continues to draw air into the compression bin 51 during the process of the tray 21 being pulled out, and the air flow continues to enter the compression bin 51, so that the surgical instruments are always close to the top of the tray 21. On the contrary, when the hinged door 14 is closed, the piston 53 slides in the compression bin 51 to blow air toward the top of the tray 21, thereby blowing away foreign objects on the surgical instruments.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
