Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adjustable clamping and fixing device for a head drainage tube. Background Technique

[0002] Neurosurgery is a branch of surgery. Based on surgery as the main treatment method, it applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related affiliated organs, such as the skull, cerebral blood vessels, meninges, and scalp. It studies the causes and pathogenesis of diseases such as injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or functional disorders of these structures, such as epilepsy, Parkinson's disease, neuralgia, etc. Neurosurgery mainly treats diseases of the nervous system such as the brain and spinal cord caused by trauma. For example, the amount of intracerebral hemorrhage endangers life, a car accident causes brain trauma, or a brain tumor compresses and requires surgical treatment. In the neurosurgery departments of major hospitals, subcutaneous hydrops is a very common complication after craniotomy. The main reason is the leakage of cerebrospinal fluid, followed by inflammatory reactions and exudation of cellular tissues. When there is subcutaneous hydrops in the patient's scalp, a craniotomy needs to be performed on the patient to create a wound at the position where there is subcutaneous hydrops in the patient's scalp and perform external drainage of the hydrops.

[0003] At present, an adjustable clamping and fixing device for a head drainage tube, as described in the patent with publication number CN110559546A, includes a support mechanism. A circumferential side of the bottom of the support mechanism is provided with an elastic fixing ring. A bottom of the elastic fixing ring is provided with an elastic fixing mechanism. An outer surface of the support mechanism is provided with a ventilation mechanism. A center of an outer surface of the ventilation mechanism is provided with a tube-passing mechanism. A drainage tube is inserted through a center of the tube-passing mechanism. A fixing mechanism corresponding to the drainage tube is provided on one side of an outer surface of the ventilation mechanism. An elastic telescopic mechanism is provided at an end of the fixing mechanism close to a second tube-passing hole. During use, by designing the fixing mechanism and the elastic telescopic mechanism, the drainage tube can be effectively fixed to prevent the backflow of hydrops and accidental extubation. However, during the drainage process of this device, a head cap is worn on the patient's head, and the device is fixed to the patient's head through an elastic rope. However, since the head cap is fixed to the patient's head through the elastic rope, the head cap always presses on the patient's wound, which easily causes pain in the patient's wound and also affects the recovery of the wound. Content of the Utility Model

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: The adjustable clamping and fixing device for a head drainage tube has a reasonable structure and has the following advantages:

[0015] (1) By moving the second annular shell in the first annular shell and fixing the relative position between the second annular shell and the first annular shell through the cooperation between the fastening bolt and the internal thread limit hole, the first annular shell and the second annular shell are adapted to the patient's head. And through the action of the first cotton pad and the second cotton pad, the materials of the first cotton pad and the second cotton pad are soft, which can reduce the extrusion of the device on the patient's head, and thus replace the traditional head cap to press the patient's wound. The device can adjust the size of the device according to the size of the patient's head, and has strong practicability.

[0016] (2) After rotating the adjusting ring to a suitable position, rotate the fastening bolt again. The front end of the fastening bolt enters the avoidance hole, and at the same time, the convex platform cooperates with the limit counterbore to lock the position of the adjusting ring. Then, by moving the moving part, the moving part can move on the adjusting ring, and by rotating the adjusting bolt, the adjusting bolt will be inserted into the second sliding groove for fixation, so that the position of the moving part corresponds to the position of the drainage tube. Thus, the drainage tube can be passed through the clamping sleeve, and then by rotating the fixing bolt, the clamping ring will clamp the outside of the drainage tube to fix the drainage tube. The structure is simple and convenient to operate.

[0017] (3) By sleeve-fitting the protective cap body on the outer sides of the first annular shell and the second annular shell, not only the internal fixing device and drainage tube can be shielded, thus increasing the aesthetics of the device, but also the protective cap can be used to keep the patient warm.
