Description

Technical Field

[0001] The utility model relates to the technical field of debridement instruments, in particular to a debridement instrument for chronic wounds. Background Technique

[0002] Diabetes is a very common chronic disease, and diabetic foot is a complication that diabetic patients are very likely to develop after suffering from diabetes. If the patient does not receive timely treatment and the gangrene of the patient's foot continues to develop, it may lead to the formation of relatively serious foot ulcers on the patient's foot. Many patients have to undergo amputation as a result. When debriding the wounds of diabetic foot patients, it is necessary to be thorough, thoroughly clean the necrotic tissue and exudate of the wound surface. By debriding the wound, the symptoms of the patient's wound ulcer can be well controlled, and the further aggravation of the ulcer can be avoided.

[0003] However, when debriding diabetic foot patients, auxiliary personnel are needed to assist in fixing the patient's legs during debridement. However, during the debridement process, the patient's legs may suddenly retreat due to fear, resulting in unstable fixation of the patient's legs by the auxiliary personnel during the debridement process, affecting the debridement effect.

[0004] An existing patent (publication number: CN117379268A) discloses an auxiliary debridement device for diabetic foot wounds, which is mainly used for: relatively fixing the patient's legs when debriding the gangrene of diabetic foot patients; a main body part provided with a connecting base; a supporting bracket configured on the connecting base for placing the patient's legs; a first fixing component connected to the connecting base; and a second fixing component connected to the connecting base and opposite to the first fixing component in position. The first fixing component and the second fixing component are configured to move closer to each other in the direction of the supporting bracket when the supporting bracket is stressed and descends, so that the patient's legs are restricted between the supporting bracket, the first fixing component and the second fixing component. By restricting the patient's legs on the supporting bracket, it avoids the problem that during the debridement process, the patient's legs may suddenly retreat due to fear, resulting in unstable fixation of the patient's legs by the doctor during the debridement process and affecting the debridement effect.

[0005] However, the above technical solution still has certain defects. During use, the height of the supporting bracket is fixed, and most diabetic patients are older and their limbs are relatively stiff. The supporting bracket in the above technology cannot adjust the height of the supporting bracket according to the body postures of different patients, resulting in the patient not being able to be in a more comfortable position during debridement, reducing the comfort of the patient during the treatment process. Therefore, a debridement instrument for chronic wounds is proposed. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention.

[0027] Next, the embodiments of the present invention will be described according to its overall structure.

[0028] A chronic wound debridement instrument, such as Figures 1 to 5 shown, includes a base 1, and a platform 2 is provided at the top end of the base 1;

[0029] The base 1 includes a bottom plate 101. A plurality of sets of sleeves 102 are fixedly connected to the top end of the bottom plate 101. A set of support rods 103 are respectively slidably connected to the inner walls of the plurality of sets of sleeves 102. The top ends of the plurality of support rods 103 are fixedly connected to the bottom end of the platform 2. Two sets of chutes 104 are fixedly connected to the top end of the bottom plate 101. A sliding rod 105 is slidably connected between the two sets of chutes 104. Two sets of top rods 106 are hinged to the top end of the sliding rod 105. The top ends of the two sets of top rods 106 are rotatably connected to the bottom end of the platform 2. A threaded rod 107 is threadedly connected to the inner wall of the sliding rod 105. The end of the threaded rod 107 is rotatably connected to the top end of the bottom plate 101. A plurality of universal wheels 3 are installed at the bottom end of the bottom plate 101, and the plurality of universal wheels 3 are respectively distributed at the four corners of the bottom end of the bottom plate 101.

[0030] By rotating the threaded rod 107, the threaded rod 107 is made to push the sliding rod 105 to slide between the two sets of chutes 104. During the sliding process of the sliding rod 105, the sliding rod 105 pushes the top rod 106 so that the top rod 106 pushes the platform 2 upward to rise. By rotating the threaded rod 107 in the reverse direction, the threaded rod 107 is made to push the sliding rod 105 to slide in the reverse direction, so that the sliding rod 105 pulls the platform 2 downward through the top rod 106, thereby realizing the adjustment of the height of the platform 2.

[0031] Please refer specifically to Figure 2 and Figure 5, the support platform 2 includes a support frame 201. The support frame 201 is fixedly connected to the tops of multiple support rods 103. A collection groove 204 is slidably connected to the inner wall of the support frame 201. A push handle 4 is fixedly connected to the side wall of the support frame 201. A rubber sleeve is sleeved on the outer wall of the push handle 4. Two limit posts 202 are rotatably connected to the side wall of the support frame 201. A support plate 203 is fixedly connected between the two limit posts 202. The support plate 203 includes a rotating plate 2031. The rotating plate 2031 is fixedly connected between the two limit posts 202. Two mounting grooves 2032 are respectively fixedly connected to both sides of the rotating plate 2031. A mounting strip 2033 is slidably connected to the inner wall of each of the two mounting grooves 2032. A sterile gauze 2034 is fixedly connected between the two mounting strips 2033. A magnet 2035 is fixedly connected to the bottom end of the sterile gauze 2034. A limit pin 205 is slidably connected to the connection part of the support frame 201 and the limit post 202. The bottom end of the limit pin 205 is slidably attached to the outer wall of the limit post 202. One end of a return spring 206 is fixedly connected to the side wall of the limit pin 205, and the other end of the return spring 206 is fixedly connected to the inner wall of the support frame 201.

[0032] By pushing the limit pin 205 to compress the return spring 206, the limit pin 205 is made not to contact the limit post 202. Then, the rotating plate 2031 is pushed so that the rotating plate 2031 drives the limit pin 205 to rotate. When the rotating plate 2031 rotates to a certain angle, the limit pin 205 is released. At this time, the return spring 206 pushes the limit pin 205 to reset, so that the bottom end of the limit pin 205 fits against the outer wall of the limit post 202. Since the cross-section of the limit post 202 is a regular polygon, after the plane on the outer wall of the limit post 202 contacts the bottom end of the limit pin 205, the limit post 202 is blocked by the limit pin 205, so that the limit post 202 cannot rotate, and the rotating plate 2031 cannot rotate, thus realizing the angle adjustment of the rotating plate 2031. During use, the patient's calf is placed on the rotating plate 2031. After use, by pulling the sterile gauze 2034, the sterile gauze 2034 drives the magnet 2035 to separate from the rotating plate 2031. Then, the mounting strip 2033 is pulled out. Next, when in subsequent use, the mounting strip 2033 with a new sterile gauze 2034 is inserted into the mounting groove 2032, so that it can be cleaned more quickly and conveniently after use.

[0033] During use, by rotating the threaded rod 107, the sliding rod 105 drives the ejector rod 106, thereby pushing the support platform 2 to rise or fall. During the debridement of the patient, the height of the support platform 2 can be adjusted according to the patient's body size and posture, thus improving the patient's comfort and reducing the problem that the elderly are not flexible enough to lift their legs onto the support platform 2 conveniently. The parts not involved in this device are the same as the prior art or can be implemented using the prior art.
