Description

Multifunctional debridement knife

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to multi-functional debridement sword.

Background

With the improvement of living standard of people, lower limb ulcers and chronic infection wounds are common wound types of vascular surgery, acute open injuries of orthopedics and pyogenic osteomyelitis are also common wounds needing debridement. The existing common forceps or tissue scissors for debridement debride necrotic tissues, due to the limited range of motion of equipment, deep tissues are easy to generate dead corners, some wounds with deep sinuses are deep and need to be subjected to light focusing by an assistant, some wounds need to be cleaned by hydrogen peroxide or normal saline, the deep wounds are generally difficult to be washed by enough liquid, the healing of the tissues and the wounds can be affected if the washed liquid is not discharged in time, and the psychological and economic burden of a patient can be increased due to the fact that the wounds are not healed for a long time.

SUMMERY OF THE UTILITY MODEL

The utility model provides a multifunctional debridement knife with the functions of illumination, flushing and suck back, which solves the disadvantages of the prior art.

In order to solve the technical problem, the utility model adopts the following technical scheme: the multifunctional debridement knife comprises a holding handle, wherein a debridement head is arranged at the front end of the holding handle, the rear end of the holding handle is connected with a negative pressure joint, a plurality of suction holes are formed in the outer surface of the debridement head, the interior of the debridement head is of a cavity structure, a cavity of the debridement head is connected with the negative pressure joint through a suction tube, and the suction tube is arranged in the holding handle; a cleaning containing pipe is fixed on the holding handle, a spray head is arranged at the front end of the cleaning containing pipe, and the rear end of the cleaning containing pipe is opened and connected with a compressed air bag;

the periphery of the front end part of the holding handle is provided with a plurality of LED lamps, a battery cavity is formed in the holding handle, a battery is assembled in the battery cavity of the holding handle and connected with the LED lamps through electric wires, a battery cover is installed at the battery cavity of the holding handle, and a switch used for controlling the LED lamps is further arranged on the holding handle.

The debridement head is conical in shape, and a plurality of scraping thorns are uniformly distributed on the outer surface of the debridement head.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the debridement head is conical, so that dead corners which cannot be touched by debridement of the traditional forceps can be greatly reduced, and the outer surface of the debridement head is provided with the scraping thorns, so that the debridement efficiency can be improved, and necrotic tissues and foreign matters can be more thoroughly removed; the debridement head is provided with suction holes, so that necrotic pus or physiological saline or hydrogen peroxide left during debridement can be sucked away in time to promote better healing of the wound; the head part of the holding handle is provided with a plurality of LED lamps which can provide visible brightness for deep tissues so as to avoid that a wound is not healed late due to omission of certain necrotic tissues; the device is also provided with a cleaning accommodating tube which can be filled with hydrogen peroxide or normal saline, can absorb 20ml of cleaning solution liquid and wash deep tissues so as to better clean foreign matters or necrotic tissues.
