Investigating the Impact of 'Admission-Discharge-Family Follow-up' Health Education on Insulin Injection Effectiveness and Compliance in Diabetes Patients.

Objective: To investigate the impact of comprehensive health education on insulin therapy outcomes in diabetic patients.

Methods: A total of 130 diabetes mellitus patients admitted to our hospital between January 2020 and January 2023 were enrolled. We used a randomization method to divide participants into two groups, one of which received the "admission-discharge-home follow-up" comprehensive health education program and the other which did not.

A dual-use imaging system for pre-clinical small animal radiation research.

The current cone beam computed tomography (CBCT) system on the small animal radiation research platform (SARRP) is less effective in localizing soft-tissue targets. On the contrary, molecular optical imaging techniques, such as bioluminescence tomography (BLT) and fluorescence tomography (FT), can provide high contrast soft tissue images to complement CBCT and offer functional information. In this study, we present a dual-use optical imaging system that enables BLT/FT for both on-board and stand-alone applications.

FBG-based sensorized light pipe for robotic intraocular illumination facilitates bimanual retinal microsurgery.

In retinal surgery, microsurgical instruments such as micro forceps, scissors and picks are inserted through the eye wall via sclerotomies. A handheld intraocular light source is typically used to visualize the tools during the procedure. Retinal surgery requires precise and stable tool maneuvers as the surgical targets are micro scale, fragile and critical to function.

IRIS: Integrated Robotic Intraocular Snake.

Retinal surgery is one of the most technically challenging surgical disciplines. Many robotic systems have been developed to enhance the surgical capabilities. However, very few of them provide the surgeon the dexterity within the patient's eye to enable more flexible, more advanced surgical procedures.

Toward robotically assisted membrane peeling with 3-DOF distal force sensing in retinal microsurgery.

Retinal microsurgery requires steady and precise manipulation of delicate eye tissues in a very small space. Physiological hand tremor and lack of force sensing are among the main technical challenges, limiting surgical performance. We present a system that consists of the cooperatively controlled Steady-Hand Eye Robot and a miniaturized 3-DOF force sensing instrument to address these limitations.

Development of A Miniaturized 3-DOF Force Sensing Instrument for Robotically Assisted Retinal Microsurgery and Preliminary Results.

Lack of force sensing is one of the most formidable technical challenges in retinal microsurgery. Incorporating high sensitivity force sensing into the ophthalmic tools has the potential to provide the surgeon useful force feedback and to enable safe robotic assistance. This paper presents a new design of a three degrees of freedom force sensing instrument based on fiber Bragg grating sensors.

A Multi-Function Force Sensing Instrument for Variable Admittance Robot Control in Retinal Microsurgery.

Robotic systems have the potential to assist vitreoretinal surgeons in extremely difficult surgical tasks inside the human eye. In addition to reducing hand tremor and improving tool positioning, a robotic assistant can provide assistive motion guidance using virtual fixtures, and incorporate real-time feedback from intraocular force sensing ophthalmic instruments to present tissue manipulation forces, that are otherwise physically imperceptible to the surgeon. This paper presents the design of an FBG-based, multi-function instrument that is capable of measuring mN-level forces at the instrument tip located inside the eye, and also the sclera contact location on the instrument shaft and the corresponding contact force.

A Novel Dual Force Sensing Instrument with Cooperative Robotic Assistant for Vitreoretinal Surgery.

Robotic assistants and smart surgical instruments have been developed to overcome many significant physiological limitations faced by vitreoretinal surgeons, one of which is lack of force perception below 7.5 mN. This paper reports the development of a new force sensor based on fiber Bragg grating (FBG) with the ability to sense forces at the tip of the surgical instrument located inside the eye and also provide information about instrument interaction with the sclera.

A submillimetric 3-DOF force sensing instrument with integrated fiber Bragg grating for retinal microsurgery.

Vitreoretinal surgery requires very fine motor control to perform precise manipulation of the delicate tissue in the interior of the eye. Besides physiological hand tremor, fatigue, poor kinesthetic feedback, and patient movement, the absence of force sensing is one of the main technical challenges. Previous two degrees of freedom (DOF) force sensing instruments have demonstrated robust force measuring performance.

Miniature fiber-optic force sensor for vitreoretinal microsurgery based on low-coherence Fabry-Pérot interferometry.

Vitreoretinal surgery requires delicate manipulation of retinal tissue. However, tool-to-tissue interaction forces in the order of sub-millinewton are usually below the human sensory threshold. A surgical force sensor (FS) compatible with conventional surgical tools may significantly improve the surgery outcome by preventing tissue damage.

A force-sensing microsurgical instrument that detects forces below human tactile sensation.

Purpose: To test the sensitivity and reproducibility of a 25-gauge force-sensing micropick during microsurgical maneuvers that are below tactile sensation.

Methods: Forces were measured during membrane peeling in a "raw egg" and the chick chorioallantoic membrane models (N = 12) of epiretinal membranes. Forces were also measured during posterior hyaloid detachment and creation of retinal tears during vitrectomy in live rabbits (n = 6).

Miniature fiber-optic force sensor based on low-coherence Fabry-Pérot interferometry for vitreoretinal microsurgery.

During vitreoretinal surgery, the surgeon manipulates retinal tissue with tool-to-tissue interaction forces below the human sensory threshold. A force sensor (FS) integrated with conventional surgical tools may significantly improve the surgery outcome by providing tactile feedback to the surgeon. We designed and built a surgical tool integrated with a miniature FS with an outer diameter smaller than 1 mm for vitreoretinal surgery based on low-coherence Fabry-Pérot (FP) interferometry.
