An apparatus for treating or preventing venous deficiency, thrombus development, orthostatic intolerance, lymphedema, and / or edema comprising a sleeve wearable on a limb of a user; an upper bracket and a lower bracket releasably couplable to the limb; an actuator coupled to one of the upper or lower brackets; a shaft coupled to the actuator and the other of the upper or lower brackets; a plurality of cams fixedly coupled to, and longitudinally spaced along, the shaft; and a respective plurality of flexible elements each coupled to one of the plurality of cams and to the sleeve. Rotational motion of the actuator about an axis of rotation causes the plurality of cams, via the respective plurality of flexible elements, to induce a peristaltic pressure wave in the limb.

The invention relates to a post-operative compression garment designed to compress a part of a patient's body, characterised in that it comprises: at least one compression textile and a plurality of silicone tracks (1) arranged on a plurality of support strips arranged on a face of the compression textile intended to be in contact with the skin of the patient, the support strips having a common point in an upper portion of the garment, the distance between the support strips increasing at an increasing distance from the common point so that the silicone tracks adhere to the skin of the patient along a respective lymphatic drainage path of said part of the patient's body.

The application relates to the technical field of medical devices, in particular to a skin ultrasound contrast-based axillary sentinel lymph node puncture guiding method. The core of the method is as follows: after injecting an ultrasound contrast agent with a specific particle size through the skin, a preset low-mechanical-index high-frame-rate double-amplitude contrast imaging mode is adopted to dynamically track lymph drainage and sentinel lymph node development, and the enhancement characteristics are recorded; then, under the guidance of multimodal imaging which is fused with real-time contrast, elastic imaging and color Doppler, the target lymph node is accurately punctured and biopsied, and a tissue sample is obtained for pathological analysis. The application realizes integrated operation from sensitive development of the sentinel lymph node, function evaluation to accurate puncture, and provides a non-radiation high-precision puncture guiding method for accurate evaluation of the axillary lymph node state of breast cancer patients before operation.

This invention relates to a cannulation device and manufacturing method for draining intestinal lymphatic fluid in small animals. The device includes a catheter and a guidewire. The catheter includes an insertion section and a drainage section, the outer and inner diameters of which are smaller than those of the drainage section. The guidewire can be inserted along the catheter, and its outer diameter is smaller than the inner diameter of the insertion section. The insertion tip of the guidewire is blunt and rounded, and the tail end of the guidewire is provided with a handle. By using the cannulation device of this invention, the problems of difficult catheter insertion and significant damage to the mesenteric lymphatic vessels during pretreatment in existing intestinal lymphatic fluid drainage cannulation techniques are solved, reducing the difficulty of surgical operation, shortening the operation time, reducing tissue damage, and improving the success rate of surgery.

The Ultrasound Lymphatic Treatment System and associated Manual and Ultrasound-Enhanced Lymphatic Drainage Method provide an integrated solution for preoperative and postoperative lymphatic stimulation. The system comprises a programmable ultrasound delivery subsystem, manual drainage implements, and a protocol-driven control module with real-time sensor feedback. The method includes individualized patient evaluation, mapping of lymphatic zones, and sequential application of manual drainage and low-frequency ultrasound along anatomically validated pathways. The system generates a patient-specific lymphatic zone map and session ultrasound parameter set, enabling reproducible, zone-targeted therapy. Closed-loop regulation of ultrasound parameters and contact pressure ensures safety and efficacy. The invention standardizes the combination of manual and ultrasound modalities, accelerates edema resolution, reduces pain, and supports immune recovery, addressing the lack of coordinated, evidence-based lymphatic care in surgical patients.

This invention provides an artificial dura mater material, its preparation method, and its applications, belonging to the field of biomedical technology. Addressing the shortcomings of traditional synthetic dura mater, this invention utilizes poly(L-lactide-caprolactone) (PLCL) with a specific concentration of RAPA, processed using electrospinning. It exhibits low porosity and a dense texture, inducing rapid endothelialization of the dura mater in the early stages of traumatic brain injury. Subsequently, with the release of RAPA, the material's porosity increases, facilitating the proliferation and growth of newly formed dura mater cells. Simultaneously, RAPA can prevent excessive proliferation of new endothelial cells and scar hyperplasia. It can selectively inhibit pathological proliferation without impairing necessary lymphatic drainage; while maintaining the physical structural integrity of the dura mater, it can promote neurological function repair.

The application discloses a thyroid cancer lateral neck lymph node metastasis endoscope-assisted modified Miccoli precise treatment system, and the system is operated through the following method, the method comprises the following steps: constructing a patient individualized three-dimensional anatomical model through preoperative multi-modal image fusion, and extracting the spatial topological relationship of the cervical sheath, accessory nerve, cervical plexus branch and lymphatic drainage path; planning a minimally invasive access path based on the three-dimensional anatomical model, and setting a double-channel puncture point at the posterior edge of the sternocleidomastoid muscle and 2 cm above the clavicle, which is respectively used for inserting a 30° oblique vision endoscope and a variable-angle ultrasonic aspirator; collecting tissue displacement data in real time through an electromagnetic navigation probe during the operation, and dynamically registering the preoperative model to generate a corrected navigation guide map; and the application aims to solve the problems of insufficient cleaning range, unclear anatomical level, limited operation space and disconnection between intraoperative real-time navigation and postoperative verification of the traditional Miccoli operation in the treatment of lateral neck (II-IV area) lymph node metastasis.
