Objective: To observe the effect of moxibustion, catgut embedding and acupuncture on allergic symptoms and expression of interferon-γ (IFN-γ) and interleukin-4 (IL-4) of nasal mucosa in rats with allergic rhinitis (AR) based on acupoint injection, so as to explore their synergistic effect and related mechanism in relieving AR.

Methods: SD rats (half male half female) were randomly divided into normal control, model, acupoint injection (AI), AI+moxibustion, AI+catgut embedding and AI+acupuncture groups, with 8 rats in each group. The AR model was established by intraperitoneal injection of ovalbumin suspension (once every other day for 7 times), and intranasal drop of 0. Read More

Objective: To systematically review the occurrence of adverse events/adverse reactions (AEs/ARs) induced by acupoint catgut embedding therapy for psoriasis vulgaris (PV) and its safety.

Methods: Randomized controlled trials, controlled clinical trials, cohort studies, case-control studies, case-series, and case reports concerning the treatment of PV with acupoint catgut embedding therapy were searched from Chinese and English databases from their inception to January 7, 2021. The AEs/ARs related to acupoint catgut embedding therapy for PV were subjected to descriptive statistics, followed by the analysis of possible reasons. Read More

This human cadaver study investigated whether flexor tendon repairs performed with round-bodied needles had a higher risk of pull-out compared with those performed with cutting needles. Forty human cadaver tendons were repaired (20 with each type of needle), subjected to tensile traction testing and evaluated by failure load and mode of failure. The average failure load was 50 N (SD 13 N) for tendons repaired with round-bodied needles, compared with 49 N (SD 16 N) for tendons repaired with cutting needles. Read More

Wound closure with surgical sutures is a critical challenge for flexible endoscopic surgeries. Substantial efforts have been introduced to develop functional and smart surgical sutures to either monitor wound conditions or ease the complexity of knot tying. Although research interests in smart sutures by soft robotic technologies have emerged for years, it is challenging to develop a soft robotic structure that possesses a similar physical structure as conventional sutures while offering a self-tightening knot or anchor to close the wound.

Patients suffer from persistent ulnar wrist pain and distal radioulnar joint instability because of chronic triangular fibrocartilage complex (TFCC) foveal tear are treated with TFCC reconstruction. We performed an arthroscopic TFCC reconstruction using a palmaris longus tendon graft that provided a minimally invasive procedure. After confirming the TFCC foveal tear and stability between the TFCC remnant and radius, the bone tunnel was made in the ulna from the ulnar shaft to ulnar fovea. Read More

The CycleGAN framework allows for unsupervised image-to-image translation of unpaired data. In a scenario of surgical training on a physical surgical simulator, this method can be used to transform endoscopic images of phantoms into images which more closely resemble the intra-operative appearance of the same surgical target structure. This can be viewed as a novel augmented reality approach, which we coined Hyperrealism in previous work. Read More

This article presents a medical robotic system for deep orbital interventions, with a focus on Optic Nerve Sheath Fenestration (ONSF). ONSF is a currently invasive ophthalmic surgical approach that can reduce potentially blinding elevated hydrostatic intracranial pressure on the optic disc via an incision on the optic nerve. The prototype is a multi-arm system capable of dexterous manipulation and visualization of the optic nerve area, allowing for a minimally invasive approach. Read More

Despite focus on prevention of needlestick injuries, intraoperative injuries involving suture needles have increased in the past two decades. When interruptions occur during surgery, a practitioner's focus is disengaged, creating an "error space;" re-engagement of the practitioner takes exponentially longer as each subsequent interruption occurs during the procedure. Human factors studies focus on the interaction between individuals and the environment in which they work (eg, processes, equipment). Read More

Cecal ligation and puncture (CLP) is referred to as the "gold standard" rodent model for abdominal sepsis. CLP creates a continuously leaking, polymicrobial infectious focus in the abdomen. The abdominal cavity is opened under general anesthesia and analgesia and the cecum is exposed, ligated underneath the ileocecal valve, and punctured with a needle. Read More

The procedure involved an ab-externo scleral fixation technique using a double-armed 10-0 polypropylene suture with straight needles that require no scleral flaps. The IOLs are sutured to the sclera, the free suture ends are tied to the suture loops, and they are buried together under the sclera. Forty eyes of 37 patients were included. Read More

Inside-out meniscal repair is considered the gold standard for reparable tears of the medial and lateral menisci despite the recent popularity of all-inside devices. Accurate suture passage is required to perform a stable repair as well as to prevent inadvertent neurovascular injury from the suture needles. Placement of a deep soft-tissue retractor is necessary to identify and retrieve these needles prior to tying the sutures. Read More

Purpose: To describe a flapless/grooveless technique for four-point refixation of a dislocated intraocular lens (IOL) with four fenestrated haptics.

Methods: An intraocular suture looping technique was performed with the assistance of two 27-gauge needles. A looping needle was passed into the eye through paracentesis and was used to loop both fenestrated haptics on the same side with an 8-0 polypropylene thread. Read More

Technical advancements in meniscal repairs have greatly contributed to the ability to repair a variety of meniscal tears that were once thought untreatable. The gold-standard treatment for arthroscopic meniscal body repair remains an inside-out technique. The advantages of this technique are innate to the low-profile nature of the suture-passing construct, which allows for perpendicular access to tears with the benefit of multiple fixation points, in contrast to often bulkier all-inside repair devices.

The purpose of this study was to describe a new 33-gauge hypodermic needle-guided iris suturing technique for repair of iris defects and its adaptation for use to address a wide range of iris pathology in complex anterior segment reconstruction cases. This approach uses a 33-gauge hypodermic needle loaded with a 10-0 Prolene suture within its lumen, which is then used to directly introduce and manipulate the suture within the anterior chamber. Eliminating the need for a needle holder, this technique provides surgeons improved ergonomics and minimizes risk for trauma to adjacent tissues. Read More
