Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a limb wound debridement and repair device. Background Art

[0002] Debridement is a surgical procedure that removes foreign matter from open wounds, excises necrotic, inactive or severely contaminated tissue, sutures wounds, minimizes contamination and even cleans wounds, achieves primary healing, and is beneficial to the recovery of the function and morphology of the injured area.

[0003] Wound healing is generally divided into primary healing and secondary healing. Primary healing is seen in wounds with little tissue loss, neat wound edges, no infection, and close wound surfaces after bonding or suturing. Secondary healing is seen in wounds with larger wounds, more necrotic tissue, accompanied by infection or wounds that have not been promptly and well treated by surgery. The purpose of trauma treatment is to make the wound recover better (try to achieve primary healing) and faster (debridement, anti-infection, etc.)

[0004] When encountering a patient with a fracture, it is usually necessary to first treat the injury at the fracture site and fix the fracture site to relieve pain, reduce bleeding, and enable the patient to tolerate the debridement surgery. However, such an operation will waste a lot of time and affect the optimal time for debridement, and thus cannot be sutured in the first stage, affecting wound healing. Based on this, we proposed a limb wound debridement and repair device. Utility Model Content

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0022] like Figure 1-2 As shown, a limb wound debridement and repair device includes a base 1, a splint 2 and an observation device 3. Two splints 2 are arranged at the upper end of the base 1. The two splints 2 can be clamped relative to each other. The observation device 3 is arranged on the upper end surface of the base 1. The two splints 2 fix the patient's fractured leg on the base 1 and fix the fracture site to relieve pain and reduce bleeding, so that the patient can tolerate the debridement surgery. Medical personnel can observe the patient's wound through the observation device 3 to improve the debridement effect.

[0023] The base 1 includes a notch 101, a support plate 102 and a drain port 103. The upper end surface of the base 1 is recessed inward to form a notch 101. An arc-shaped support plate 102 is arranged at the upper opening of the notch 101. A leaking hole 1021 is arranged on the support plate 102. A drain port 103 is opened on one side of the notch 102. The wound needs to be cleaned during the debridement operation. The sewage generated during the cleaning process flows into the notch 101. The arc-shaped support plate 102 can ensure that the patient's limbs will not contact the sewage in the notch 101. The leaking hole 1021 opened on the support plate 102 allows the sewage to easily flow into the notch 101 and is not easy to accumulate on the support plate 102. The drain port 103 opened on one side of the notch 101 can discharge the sewage in time, so that the base 1 will not be submerged by a large amount of sewage, which will affect the debridement operation.

[0024] The splint 2 includes an arc-shaped abutment plate 201 and a threaded rod 202. The threaded rod 202 is arranged at the center of the rear end surface of the arc-shaped abutment plate 201. The threaded rod 201 passes through the boss 104 raised on the upper end surface of the base. A nut-style knob 4 is connected to one side of the boss 104 through a bearing. An internal thread is arranged inside the knob 4, which cooperates with the external thread on the threaded rod 202. The threaded rod 202 passes through the boss 104 and cooperates with the knob 4. The arc-shaped abutment plate 201 can fit the patient's limbs more closely, so that the patient's fracture is firmly fixed and the secondary injury to the patient caused by the fracture is reduced. The threaded rod 202 passes through the boss 104 and cooperates with the knob 4 axially connected to the boss 104 through threads. Medical personnel can rotate the knob 4 to adjust the distance between the two splints 2, and the operation is simple.

[0025] A soft pad 203 made of silicone material is arranged at the front end of the arc-shaped abutment plate 201. The soft pad 203 made of silicone material is used to pad the contact area between the abutment plate 201 and the patient's limbs to prevent further compression and friction damage.

[0026] Two traction rods 204 are provided at the rear end of the splint 2, passing through the traction platform 105 protruding from the upper end surface of the base 1. The traction rods 204 cooperate with the traction platform 105 to keep the splint 2 in a horizontal posture and prevent it from shaking at will, thereby making the splint 2 more firmly fixed.

[0027] The observation device 3 includes a rotating base 301, a first support rod 302, a second support rod 303 and an observation mirror 304. The rotating base 301 is connected to the boss 104 protruding from the upper end of the base through a bearing and can rotate relative to the boss 104. The first support rod 302 is hinged on the rotating base 301, and the other end of the first support rod 302 is connected to the second support rod 303 through a spherical joint. The other end of the second support rod 303 is fixedly connected to the observation mirror 304. The rotating base 301 can rotate relative to the boss 104, and the observation mirror 304 can freely adjust its posture through the first support rod 302, the second support rod 303 and the rotating base 301, so that medical personnel can observe the patient's wound area from multiple angles.

[0028] The lens material of the observation mirror 304 is selenium red glass (HB). There are differences in the spectral characteristics of normal tissue and inactivated tissue, and the difference is mainly reflected in the red light above 600nm. Selenium red glass (HB) can selectively transmit the red light of 600nm, and almost no light of other wavelengths will be transmitted. Medical personnel will see normal tissue as pale through selenium red glass (HB), and inactivated tissue will be obviously black, which is helpful for medical personnel to identify normal tissue and inactivated tissue.
