Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a pulse-type temperature-controlled flushing device for general surgical operations. Background Art

[0002] Surgery is the science that studies the occurrence, development, and clinical manifestations of surgical diseases, as well as their diagnosis, prevention, and treatment. It is a specialized department that primarily treats diseases through surgical resection and repair. With the application of microsurgical techniques, surgery has experienced significant development. The principles for establishing surgical specialties in hospitals are similar to those for internal medicine, and they usually correspond to internal medicine. Surgical diseases are categorized into five main categories: trauma, infection, tumor, deformity, and dysfunction.

[0003] When performing surgical irrigation, general surgeons often use a simple airbag to squeeze the prepared liquid medicine onto the patient's affected area. In addition, previous irrigation methods cannot effectively control the flow of the liquid medicine, which can easily cause irreparable damage to damaged cells and other tissues in the affected area. In addition, traditional irrigation methods cannot absorb tissue, fat and waste liquid while irrigation, which affects the doctor's ability to distinguish cell tissues in a complex surgical environment. At the same time, it is easy to increase the chance of wound infection. If the patient's body is infected, it will cause secondary damage to the patient's body.

[0004] Therefore, it is necessary to provide a new pulse temperature-controlled flushing device for general surgery to solve the above technical problems. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a pulse temperature-controlled flushing device for general surgery.

[0006] The pulsed temperature-controlled flushing device for general surgery provided by the present invention comprises a housing, a pulsed temperature-controlled flushing assembly, and a flushing liquid holder. The pulsed temperature-controlled flushing assembly and the flushing liquid holder are fixedly mounted on one side and the top of the housing, respectively. The flushing liquid holder is provided with a container for supplying flushing liquid, and the container is connected to the input end of the pulsed temperature-controlled flushing assembly.

[0007] The pulse-type temperature-controlled flushing assembly includes a peristaltic extrusion mechanism, a partition box, a temperature-controlled box, and a supply hose. One end of the supply hose is connected to the container, and the other end of the supply hose passes through the peristaltic extrusion mechanism and is located inside the partition box. The partition box is connected to the inner cavity of the temperature-controlled box. A flushing tube is inserted into the bottom of the temperature-controlled box. The peristaltic extrusion mechanism is fixedly installed on the outside of the partition box, and the output end of the peristaltic extrusion mechanism is in contact with the surface of the supply hose.

[0008] The interior of the partition box is divided into two independent temperature control chambers and a supply chamber by a partition. The temperature control chamber and the supply chamber are both connected to the inner cavity of the temperature control box. A temperature control component is provided inside the temperature control chamber.

[0009] Furthermore, a stabilizing component is provided on the outside of the partition box, and the stabilizing component includes a slider, a stabilizing column and a driving mechanism for driving the slider to move horizontally. The slider is slidably installed in a slide groove opened on one side of the partition box, one end of the stabilizing column is fixedly connected to one side of the slider, and the other end of the stabilizing column is located inside the partition box, and the surface of the supply hose is located between the stabilizing column and the partition.

[0010] Furthermore, the peristaltic extrusion mechanism includes a cover body, a strip plate and a rotating mechanism for driving the strip plate to rotate. The cover body is fixedly installed on the top of the partition box, and the outer side of the cover body is respectively provided with an inlet and an outlet connected to its inner cavity. One end of the supply hose passes through the inlet, strip plate and outlet in sequence. The rotating mechanism is fixedly installed on the outer side of the cover body, and the output end of the rotating mechanism is fixedly connected to one side of the strip plate. The strip plate is located inside the cover body, and both ends of the strip plate are rotatably connected to peristaltic rollers, and the surfaces of the two peristaltic rollers are in contact with the inner side of the supply hose.

[0011] Furthermore, the temperature control component includes an electric heating film, and the electric heating film is fixedly installed on the inner wall of the temperature control cavity.

[0012] Furthermore, the flushing liquid support is provided with a hanging ring, one end of which is connected to the top of the container.

[0013] Furthermore, a conical protective cover is fixedly connected to the bottom of the flushing pipe.

[0014] Furthermore, universal casters are provided at the four corners of the bottom of the shell.

[0015] Furthermore, the driving mechanism includes a mounting frame, an adjusting screw and a connecting block. The mounting frame is fixedly installed on the outside of the partition box, the adjusting screw is rotatably installed on the mounting frame, the adjusting screw is threadedly connected to the connecting block, and one end of the connecting block is fixedly connected to one side of the slider.

[0016] Furthermore, the rotating mechanism includes a driving motor, which is fixedly mounted on the outside of the cover, and an output end of the driving motor extends into the cover, and the output end of the driving motor is fixedly connected to the middle of the strip plate.

[0017] Compared with related technologies, the pulsed temperature-controlled irrigation device for general surgery provided by the present invention has the following beneficial effects:

[0018] 1. In the present invention, the driving motor drives the strip plate to rotate through the output shaft, and the peristaltic rollers at both ends of the strip plate periodically squeeze the supply hose. The supply hose is clamped between the peristaltic roller and the cover body, and generates intermittent pulse water flow as the strip plate rotates, simulating the pulsating characteristics of human blood flow and enhancing the flushing effect. The pulse frequency is controlled by the driving motor speed to adapt to different wound needs such as chronic wounds and joint replacements, and the flushing liquid temperature and pulse pressure are synchronously adjusted. At the same time, tissue, fat and waste liquid are sucked away, which can meet the differentiated needs of low-pressure cleaning of diabetic foot ulcers and high-pressure debridement of severely infected wounds.

[0019] 2. In the present invention, the interior of the partition box is divided into two independent temperature-controlled chambers and a supply chamber by a partition. The temperature-controlled chamber adjusts the liquid temperature of the supply chamber through heat conduction. The embedded sensor in the temperature control box monitors the temperature of the flushing liquid in real time. In a low-temperature environment, heating can prevent the formation of ice crystals in the tissue fluid. Especially when flushing the bone marrow cavity, the constant-temperature liquid reduces the curing speed of bone cement and improves the fixation strength of the prosthesis.

[0020] 3. In the present invention, the adjusting screw drives the slider to move horizontally through the connecting block, and the stabilizing column adjusts the clamping position of the supply hose as the slider moves. The stabilizing column and the partition cooperate to clamp the hose to avoid the shaking of the hose caused by pulse extrusion and ensure the stability of the pulse waveform.
