Description

Technical Field

[0001] This utility model specifically relates to a surgical wound irrigation device. Background Technology

[0002] Operating room wound irrigation equipment is a specialized medical device used to promptly and efficiently irrigate external wounds in an environment outside the operating room. Its main functions are to remove contaminants from the wound, reduce the risk of infection, and create conditions for subsequent treatment.

[0003] In open wound surgery or infected surgery of the limbs, thorough rinsing of the wound site is one of the important steps in the surgical procedure. In order to improve the cleaning effect, the patient's limb needs to be elevated on the operating table before rinsing.

[0004] Therefore, a surgical wound irrigation device that can elevate the patient's limbs and is easy to use is needed.

[0005] Currently, most existing flushing devices use a simple tray. The patient's limb is placed in the tray, and then flushing is performed using a flushing solution to achieve the purpose of flushing. However, when using existing trays, the flushing solution remains in the tray after flushing. During the flushing process, debris flushed down into the wound can be flushed back into the wound, which can easily cause secondary contamination of the wound.

[0006] In addition, existing ordinary trays do not have the function of lifting limbs, and medical staff need to lift them manually, which is inconvenient to use.

[0007] Therefore, a device that is easy to use and can prevent secondary pollution is needed.

[0008] Chinese patent CN202220579144.7, entitled "A disinfection and debridement device for general surgery", describes a device including a support, characterized in that: a support plate is slidably connected to one side of the support, a rotating rod (4) is rotatably connected to one end of the support plate, and a limb support plate is fixedly connected to one end of the rotating rod.

[0009] As shown in patent CN202220579144.7, the technical solution of this patent is to adjust the height and angle of the limb support plate so that the patient's limb can be placed on the limb support plate for rinsing. It is also equipped with a drain plate to prevent waste liquid from accumulating. In addition, the patent has a disinfection tank to put non-disposable instruments and tubes used for wound cleaning into for disinfection, reducing the growth of bacteria on the instruments. The technical solution of this patent can achieve rinsing, but the technical solution of this patent is relatively complex, and the structure of the limb placement device is not reasonable. The rinsing liquid is easy to splash to the outside, causing pollution, and it is inconvenient to use. Utility Model Content

[0010] The technical problem to be solved by this utility model is that the existing surgical wound irrigation mentioned in the background art is inconvenient, requiring medical staff to elevate the limbs, and the existing irrigation devices are prone to splashing of irrigation fluid, causing secondary pollution.

[0016] In a preferred embodiment of the present invention, magnetic adsorption rings are respectively provided on the upper connecting rod and the lower connecting rod. The limiting tube can be controllably adsorbed with the magnetic adsorption rings to restrict the cooperation between the upper connecting rod and the lower connecting rod. This arrangement facilitates the restriction of the cooperation between the upper connecting rod and the lower connecting rod and is convenient to use.

[0017] In a preferred embodiment of the present invention, the rotating mechanism includes a fixed plate, a rotating plate, and an unlocking component. The fixed plate is mounted on the outer tray, and the rotating plate is connected to the fixed plate via a bearing and engages with the fixed plate via a limiting rod.

Detailed Implementation

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-10 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0024] like Figure 1 and 10 As shown, a surgical wound irrigation device includes an outer tray 1, an inner tray 2, a connecting mechanism 3, a mounting bracket 4, a rotating mechanism 5, a support bracket 6, a height adjustment mechanism 7, and a restraint strap 8.

[0025] The outer tray 1 and inner tray 2 are quickly connected by a connecting mechanism 3. The mounting frame 4 is connected to the outer tray 1 by a rotating mechanism 5. The outer tray 1 is detachably fixed to the operating table by the mounting frame 4. The support bracket 6 for placing the patient's limb is fixed to the inner tray 2 by a height adjustment mechanism 7. The height of the support bracket 6 can be adjusted by the height adjustment mechanism 7, thereby adjusting the height of the patient's limb. The restraint strap 8 for fixing the patient's limb is installed on the support bracket 6. The restraint strap 8 can fix the patient's limb to the support bracket 6 to prevent the patient from struggling due to pain during cleaning.

[0026] like Figure 1 , 2 As shown in Figure 10, the outer tray 1 is a rectangular metal tray with a certain depth. In this embodiment, it is preferably made of stainless steel. The main function of the outer tray 1 is to serve as a carrier for placing the patient's limbs when rinsing the patient's wound.

[0027] To facilitate the rapid drainage of the rinsing fluid, the interior of the outer tray 1 is arc-shaped, and a circular through hole is opened on the bottom surface of the outer tray 1. This through hole is named suction hole 12. A suction tube is connected to the suction hole 12 and is connected to an external negative pressure suction device. The rinsing fluid after wound rinsing is quickly discharged through the suction hole 12 to prevent the rinsing fluid from splashing and causing wound infection.

[0028] To improve applicability, the outer tray 1 can be placed on the operating table or fixed to the operating table by the mounting bracket 4. To facilitate the placement of the outer tray 1 on the operating table, four support feet 11 are fixed to the four corners of the bottom of the outer tray 1 with screws. The outer tray 1 can be stably placed on the operating table by the support feet 11.

[0029] like Figure 1 , 3 As shown in Figure 10, the inner tray 2 includes a tray body 21, which is a rectangular plate made of transparent material. The size of the tray body 21 is slightly smaller than that of the outer tray 1. The tray body 21 can be placed inside the outer tray 1 to divide the outer tray 1 into upper and lower layers, thus separating the irrigation fluid from the surgical field.

[0030] To facilitate rinsing and subsequent positioning, the tray body 21 is made of a transparent material, such as glass, acrylic, or other transparent materials that meet medical standards. In this embodiment, the tray body 21 is preferably made of laminated tempered glass. During the production of the tray body 21, multiple parallel metal wires are embedded inside the tray body 21. These wires are named auxiliary guide lines 23. During rinsing and subsequent surgery, the auxiliary guide lines 23 can assist in positioning and are easy to use.

[0031] When rinsing the wound, in order to facilitate the rinsing fluid to fall into the outer tray 1 below, multiple circular drain holes 22 are evenly opened on the tray body 21. When rinsing the wound, the rinsing fluid falls into the outer tray 1 below through the drain holes 22, which is convenient to use.

[0032] like Figure 2 , 3 As shown in Figures 4 and 5, in order to facilitate cleaning and disinfection of the outer tray 1 and inner tray 2 after use, the outer tray 1 and inner tray 2 are connected by a connecting mechanism 3.

[0033] The connecting mechanism 3 includes an upper connecting rod 31, a lower connecting rod 32, and a limiting tube 33. The upper connecting rod 31 is fixed to the lower surface of the pallet body 21, the lower connecting rod 32 is fixed inside the outer pallet 1, and the limiting tube 33 is movably sleeved on the upper connecting rod 31. The upper connecting rod 31 and the lower connecting rod 32 are movably engaged. The limiting tube 33 can restrict the upper connecting rod 31 and the lower connecting rod 32 after engagement, ensuring the stability of the engagement between the upper connecting rod 31 and the lower connecting rod 32.

[0034] The upper connecting rod 31 and the lower connecting rod 32 are plastic rods with rectangular cross-sections. The upper connecting rod 31 is fixed to the tray body 21 by screws, and the lower connecting rod 32 is fixed to the bottom surface of the inner cavity of the outer tray 1 by screws.

[0035] To facilitate the engagement of the upper connecting rod 31 and the lower connecting rod 32, a rectangular groove is provided on the side of the lower end of the upper connecting rod 31 and the upper end of the lower connecting rod 32, penetrating the side of the upper connecting rod 31 and the lower connecting rod 32. This groove is named the mating slot 34. The upper connecting rod 31 and the lower connecting rod 32 can be slidably engaged together from the side through the mating slot 34.

[0036] To facilitate the sliding engagement of the upper connecting rod 31 and the lower connecting rod 32 from the side, a rectangular plate protrudes from the side of the lower connecting rod 32. This rectangular plate is named the guide plate 35. A "C"-shaped boss protrudes from the guide plate 35. This boss and the guide plate 35 form a guide groove 37. The lower end of the upper connecting rod 31 can be placed in the guide groove 37. By pushing the upper connecting rod 31 along the guide groove 37, the mating slots 34 on the upper connecting rod 31 and the lower connecting rod 32 are engaged, thereby connecting the upper connecting rod 31 and the lower connecting rod 32 together.

[0037] In order to restrict the fit between the upper connecting rod 31 and the lower connecting rod 32 and ensure the stability of the fit between them, a limiting tube 33 with a rectangular cross-section is fitted onto the upper connecting rod 31. The cross-sectional dimensions of the inner side of the limiting tube 33 are the same as the cross-sectional dimensions of the upper connecting rod 31 and the lower connecting rod 32. The limiting tube 33 can be stably fitted onto the upper connecting rod 31 and the lower connecting rod 32 and can slide up and down.

[0038] To restrict the position of the limiting tube 33, an annular iron piece is embedded on each end face of the limiting tube 33. At the same time, an annular magnetic adsorption ring 36 is fixed on the upper connecting rod 31 and the lower connecting rod 32. The magnetic adsorption ring 36 is made of magnet. When the limiting tube 33 is attracted to the magnetic adsorption ring 36 on the lower connecting rod 32, the limiting tube 33 is completely fitted into the mating part of the upper connecting rod 31 and the lower connecting rod 32. At this time, the outer tray 1 and the inner tray 2 are stably connected together. When the limiting tube 33 is pulled upward, the limiting tube 33 is attracted to the magnetic adsorption ring 36 on the upper connecting rod 31. At this time, the outer tray 1 and the inner tray 2 can be detached.

[0039] like Figure 1 , 6 As shown in Figures 7 and 10, in order to facilitate the overall fixing of the device to the side of the operating table and to facilitate the adjustment of the angle of the outer tray 1, a rotating mechanism 5 and a mounting bracket 4 are provided on the outer tray 1. The outer tray 1 is connected to one end of the mounting bracket 4 through the rotating mechanism 5. The mounting bracket 4 can be detachably fixed to the operating table. The angle of the outer tray 1 relative to the operating table can be adjusted through the rotating mechanism 5.

[0040] Mounting bracket 4 is a "J"-shaped metal tube. One end of mounting bracket 4 is connected to connecting tube 41 welded to rotating mechanism 5 by screws. On the side of the other end of mounting bracket 4, two "U"-shaped metal clips are welded at intervals, named fixing clip 42. Fixing clip 42 can be clipped onto the legs of the operating table. In order to facilitate the connection between fixing clip 42 and the operating table, a fixing screw 43 is screwed onto one side of fixing clip 42. Rotating fixing screw 43 can fix fixing clip 42 onto the legs of the operating table.

[0041] Using the fixing clip 42 to fix the mounting bracket 4 to the legs of the operating table is one of the existing common methods used in this embodiment. In addition, existing C-shaped tube clamps or other similar structures that can achieve the same effect can also be used, as long as the stability of the fixation can be guaranteed, which will not be elaborated here.

[0042] The rotating mechanism 5 includes a fixed plate 51, a rotating plate 52, and an unlocking component 55. The fixed plate 51 is disposed on the lower surface of the outer tray 1. The rotating plate 52 and the fixed plate 51 are connected by a bearing. The rotating plate 52 can rotate freely relative to the fixed plate 51 along the bearing. The rotating plate 52 is connected to the mounting bracket 4. The unlocking component 55 is disposed on the rotating plate 52. The angle between the fixed plate 51 and the rotating plate 52 can be adjusted by the unlocking component 55, thereby realizing the adjustment of the angle of the outer tray 1, which is convenient to use.

[0043] The fixing plate 51 is a circular metal plate, which is welded to the lower surface of the outer tray 1. A bearing is embedded in the middle of the fixing plate 51, and the fixing plate 51 is connected to the rotating plate 52 through the bearing.

[0044] To adjust the angle, multiple circular holes are evenly provided along the center of the fixed plate 51. These holes are named limiting holes 53. The rotating plate 52 can cooperate with the limiting holes 53 through a limiting rod 510. At the same time, in order to facilitate the changing of the limiting rod 510 to the corresponding limiting holes 53, an arc-shaped guide ring 54 is recessed in the fixed plate 51 to connect all the limiting holes 53. When adjusting the angle, the limiting rod 510 can change its cooperation with different limiting holes 53 along the guide ring 54.

[0045] The rotating plate 52 is a rectangular metal plate. The rotating plate 52 is connected to the fixed plate 51 through a bearing. In order to facilitate the connection with the mounting bracket 4, a tube that can cooperate with the mounting bracket 4 is welded on the rotating plate 52. This tube is named the connecting tube 41. One end of the mounting bracket 4 can be inserted into the connecting tube 41 and fixed by a pin.

[0046] To avoid positional interference, clearance holes are provided on the fixed plate 51 and the rotating plate 52 to allow the negative pressure suction hole 12 on the external tray 1 to pass.

[0047] The unlocking assembly 55 includes an unlocking plate 56, a reset spring 58, a reset spring mounting clip 59, and a limiting rod 510. The unlocking plate 56 is a rectangular plastic plate, and the limiting rod 510 is a circular plastic rod. The limiting rod 510 is fixed on the unlocking plate 56. In order to facilitate the connection between the unlocking plate 56 and the rotating plate 52, a hinge platform 57 is fixed on the rotating plate 52. One end of the unlocking plate 56 is hinged to the rotating plate 52 through the hinge platform 57.

[0048] The reset spring mounting clip 59 is a U-shaped clip. The unlocking plate 56 passes through the reset spring mounting clip 59 and is hinged to the hinge platform 57. The reset spring 58 is fixed inside the reset spring mounting clip 59, with one end abutting against the inner side wall of the reset spring mounting clip 59 and the other end abutting against the unlocking plate 56. The limiting rod 510 is engaged with the limiting hole 53. When the unlocking plate 56 is pressed down, the unlocking plate 56 can rotate along the hinge and contact the engagement of the limiting rod 510 and the limiting hole 53. At this time, rotating the outer tray 1 can achieve angle adjustment.

[0049] like Figure 8 and 9 As shown, in order to facilitate the support of the patient's limbs, a support bracket 6 is fixed at each end of the tray body 21. A height adjustment mechanism 7 is provided on the support bracket 6. The height of the support bracket 6 can be adjusted by the height adjustment mechanism 7, thereby realizing the adjustment of the support height of the patient's limbs.

[0050] The support bracket 6 includes a support bracket body 61, a guide rod 63, and a sleeve 64. One end of the guide rod 63 is connected to the support bracket body 61, and the other end is inserted into the sleeve 64. The sleeve 64 is fixed on the tray body 21. A height adjustment mechanism 7 is provided between the sleeve 64 and the guide rod 63. The depth of the guide rod 63 inserted into the sleeve 64 can be adjusted by the height adjustment mechanism 7.

[0051] The support body 61 is an arc-shaped support made of metal. To improve comfort, a sponge wrapped in leather is fixed to the surface of the support body 61 that contacts the patient. During rinsing, to prevent the patient from shaking due to pain, two rectangular strap fixing rings 62 are fixed to both ends of the support body 61. Restraint straps 8 are fixed to the strap fixing rings 62. The restraint straps 8 and the strap fixing rings 62 can be used to fix the patient's limbs to the tray body 21.

[0052] The guide rod 63 and the sleeve 64 are made of metal. The guide rod 63 can be inserted into the sleeve 64. In order to prevent the flushing fluid from entering the sleeve 64 through the insertion point, a seal is made at the insertion point of the guide rod 63 and the sleeve 64 to prevent the flushing fluid from entering. This seal is existing technology and can be used directly.

[0053] To facilitate the fixing of the sleeve 64 to the pallet body 21, a "U"-shaped clip is welded onto the sleeve 64, which is named the mounting clip 65. The sleeve 64 is fixed to the pallet body 21 using the mounting clip 65 and screws.

[0054] The height adjustment mechanism 7 includes a worm gear mechanism 71, a gear and rack mechanism 72, a mounting box 73, and an adjustment knob 74. The mounting box 73 is a rectangular metal box, and its main function is to install the worm gear mechanism 71 and the gear and rack mechanism 72.

[0055] The rack in the gear and rack mechanism 72 is fixedly embedded in the outer wall of the lower end of the guide rod 63. The worm wheel and worm in the worm gear mechanism 71 are fixed in the mounting box 73 by the mounting shaft. The adjustment knob 74 is located outside the mounting box 73 and is connected to the worm in the worm gear mechanism 71.

[0056] To facilitate the control of the gear and rack mechanism 72 via the worm gear mechanism 71, the gear in the gear and rack mechanism 72 is fixed on the mounting shaft of the worm gear mechanism 71, and a rectangular functional hole 66 is correspondingly opened on the sleeve 64. The gear can pass through the functional hole 66 and engage with the rack. Thus, when the adjustment knob 74 is rotated, the worm gear mechanism 71 will drive the gear and rack mechanism 72 to move, thereby controlling the guide rod 63 to rise or fall, thereby realizing the adjustment of the height of the support 6.

[0057] To prevent flushing fluid from entering the mounting box 73 through the connection of the adjustment knob 74, a seal is applied to the connection of the adjustment knob 74 to prevent flushing fluid from entering. This seal is existing technology and can be used directly.

[0058] The usage process of this embodiment is as follows: First, fix the outer tray 1 on the operating table as needed, then adjust its position, then connect the inner tray 2 to the outer tray 1, then fix the patient's limb on the support 6, and adjust the support 6 to a suitable height through the height adjustment mechanism 7, and then the wound can be rinsed.

[0059] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
