Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fluid drainage and collection device for bone stripping. Background Art

[0002] When the periosteum tissue is peeled off by a stripper, blood, tissue fluid and other effusions will seep out. In order to ensure the surgical field of view, a blood sucker needs to be added to absorb the effusions. In order to improve the convenience of surgical operation, the existing device will add a liquid suction component connected to the outside world in the bone stripping component to absorb the effusions. However, in the actual operation process, the following problems will occur:

[0003] 1. When the fluid absorption component absorbs the accumulated fluid, the skin at the wound site will be adsorbed on the outer wall of the bone stripping component under the action of suction, which will interfere with the separation of the periosteum and bone by the bone stripping component, thereby increasing the difficulty of the operation;

[0004] 2. Due to the limited size of the bone stripping component, when the patient has a large amount of fluid accumulation, the fluid absorption component may not be able to completely absorb the accumulated fluid, resulting in some accumulated fluid still remaining in the patient's wound, thereby interfering with the doctor's field of vision. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a fluid drainage and collection device for bone stripping, so as to avoid the wound being adsorbed on the outer wall of the bone stripping component due to suction during fluid aspiration, thereby preventing interference with the operation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fluid drainage and collection device for bone stripping, comprising a bone stripping component and a collection and drainage component with one end arranged in the bone stripping component; the bone stripping component comprises a stripping head, a connecting strip and an operating handle connected in sequence; the collection and drainage component comprises a drainage tube whose liquid inlet end sequentially passes through the operating handle and the connecting strip and extends to the inside of the stripping head, a liquid suction pump connected to the drainage tube, and a collection bag detachably connected to the liquid outlet end of the drainage tube; a cavity is provided inside the stripping head, and a plurality of liquid suction holes connected to the outside are provided on the shell wall of the cavity at intervals, a first channel is provided through the connecting strip along the length direction, a second channel connected to the first channel is provided through the operating handle along the length direction, and the liquid inlet end of the drainage tube sequentially passes through the first channel and the second channel and is connected to the liquid outlet end of the cavity; a liquid absorbent sponge is fixed to the inner wall of each of the liquid suction holes.

[0008] More preferably, an elastic ring is fixed on the outer side of the middle part of the drainage tube, and a pair of limiting rings are fixed parallel to the inner wall of one end of the second channel away from the first channel and are respectively arranged on both sides of the elastic ring and used to clamp the elastic ring.

[0009] More preferably, a one-way valve is provided between the drainage tube and the collecting bag to control the one-way flow of liquid from the drainage tube into the collecting bag.

[0010] More preferably, the liquid inlet end of the drainage tube is threadedly connected with a liquid outlet tube communicated with the cavity.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model uses the function of the liquid pump. When the bone stripping component is in action, the accumulated fluid at the periosteum will flow from the liquid suction hole, the cavity, and the drainage tube to the collection bag for collection in sequence, so that the space for storing the accumulated fluid in the device becomes larger, and when there is a lot of accumulated fluid, part of the accumulated fluid can only be accumulated in the working area of ​​the bone stripping component due to insufficient storage space, which interferes with the doctor's surgical field of view. At the same time, the blood and tissue fluid at the periosteum are collected to prevent the patient's accumulated fluid from contaminating the bed and other areas, thereby reducing the risk of the lower patient being infected by the fluid during surgery;

[0013] 2. The utility model can reduce the situation where the skin at the wound is adsorbed to the suction hole under the action of suction force, thereby reducing the interference of the suction pump on the wound when sucking liquid;

[0014] 3. The utility model has a detachable connection between the bone stripping component and the drainage tube, which can facilitate the disinfection and cleaning of the bone stripping component on the one hand, and on the other hand, the drainage tube can be matched with bone stripping components of different models to achieve the drainage effect, without the need to replace the corresponding drainage device according to the model of the bone stripping component, thereby improving the efficiency of the operation.
